                             ABOUT THIS PROSPECTUS

     This prospectus is part of a registration statement that we filed with the
Securities and Exchange Commission, the "SEC," using a "shelf" registration
process. Under this shelf process, we may from time to time sell the debt
securities described in this prospectus in one or more offerings up to a total
dollar amount of $500,000,000.

     This prospectus provides you with a general description of the debt
securities we may offer. Each time we sell debt securities, we will provide a
prospectus supplement that will contain specific information about the terms of
that offering. The prospectus supplement may also add, update or change
information contained in this prospectus. If the terms of your debt securities
vary between this prospectus and the accompanying prospectus supplement, you
should rely on the information in the following order of priority:

     -  the prospectus supplement; and

     -  the prospectus.

     You should read both this prospectus and any prospectus supplement,
together with the additional information described under the heading "Where You
Can Find More Information."

     Unless otherwise indicated or unless the context requires otherwise, all
references in this prospectus to "NSTAR," "we," "us," "our" or similar
references mean NSTAR.

                      WHERE YOU CAN FIND MORE INFORMATION

Act of 1933 that registers the offer and sale of the securities described in
this prospectus. The registration statement, including the attached exhibits and

regulations of the SEC allow us to omit from this prospectus certain information
included in the registration statement.

     NSTAR is an energy delivery holding company serving approximately 1.3
million customers in Massachusetts, including more than one million electric

Edison Company, Commonwealth Electric Company, Cambridge Electric Light Company,
Canal Electric Company and Commonwealth Gas Company. Our nonutility operations
include telecommunications, district heating and cooling operations, liquefied

                                USE OF PROCEEDS

     Unless the prospectus supplement indicates otherwise, we anticipate adding
the net proceeds to be received from the sale of the debt securities to our
general funds, which may be used to:

     -  repay short-term debt;

     -  finance capital expenditures of non-regulated subsidiary companies;

     -  repurchase shares of our common stock; and

     -  provide working capital.

     Until all of the net proceeds are used, they may be temporarily invested in
short-term interest-bearing securities.

                         DESCRIPTION OF DEBT SECURITIES

     We will issue the debt securities under an indenture dated as of January
12, 2000, between us and Bank One Trust Company, N.A., as trustee. A copy of the
indenture is an exhibit to the registration statement that contains this
prospectus.

     The following summary of provisions of the indenture is not complete and is
subject to, and is qualified in its entirety by reference to, all of the
provisions of the indenture. The following summary describes the general terms
of the debt securities. The prospectus supplement will include the particular
terms of debt securities being offered which differ from or add to these general
terms.

     The debt securities will be unsecured and will rank equally with all other
unsecured and unsubordinated indebtedness of NSTAR. Because we are a holding
company, our rights and the rights of our creditors, including the holders of
the debt securities we are offering under this prospectus, to participate in the
assets of any of our subsidiaries upon the subsidiary's liquidation or
reorganization will be subject to the prior claims of the subsidiary's
creditors, except to the extent that we may ourselves be a creditor with
recognized claims against the subsidiary.

     The name "NSTAR" means the trustees, as trustees but not personally, under
the Declaration of Trust dated April 20, 1999, as amended from time to time. Any
obligation, agreement, or liability made, entered into, or incurred by or on
behalf of NSTAR, including the debt securities, binds only its trust estate. No
shareholder, director, trustee, officer or agent thereof assumes or shall be
held to any liability entered into on behalf of NSTAR.

GENERAL

     We may issue the debt securities from time to time, without limitation as
to aggregate principal amount and in one or more series. Neither the indenture
nor the debt securities will limit or otherwise restrict the amount of other
indebtedness, including secured indebtedness, which we may incur or other
securities which we or our subsidiaries may issue.

     The prospectus supplement will include the particular terms of the debt
securities, including:

     -  the title and series designation;

     -  the aggregate principal amount and the limit, if any, on the aggregate
        principal amount or initial public offering price of the debt securities
        of that series;

     -  any rate or rates (or method for establishing the rate or rates) at
        which the debt securities shall bear interest;

     -  the date from which any interest shall accrue;

     -  any interest payment dates;

                                        6
<PAGE>   8

     -  the stated maturity date or dates on which principal is payable;

     -  whether the debt securities are to be issued in global form;

     -  any sinking fund requirements;

     -  any provisions for redemption, and the redemption price or prices;

     -  the denominations in which the debt securities shall be issuable;

     -  whether the debt securities are denominated or payable in United States
        dollars or a foreign currency or units of two or more foreign
        currencies;

     -  the place or places where payments on the debt securities shall be made
        and the debt securities may be presented for registration of transfer or
        exchange;

     -  whether any of the debt securities will be subject to defeasance in
        advance of the date for redemption or the stated maturity date;

     -  if other than the full principal amount, the portion of the principal
        amount of the debt securities payable upon acceleration of the maturity
        of the debt securities;

     -  any index used to determine the amount of payment of principal of (and
        premium, if any) or interest on the debt securities;

     -  the person to whom any interest on the debt securities of the series
        shall be payable if other than the registered holder;

     -  any additional or different events of default that apply to debt
        securities of the series and any change in the right of the trustee or
        the required holders of those debt securities to declare the principal
        thereof due and payable;

     -  any additional or different covenants that apply to debt securities of
        the series; and

     -  any other terms of the debt securities.

     Please see the accompanying prospectus supplement for the terms of the
specific debt securities we are offering. We may deliver this prospectus before
or concurrently with the delivery of a prospectus supplement.

     We may issue debt securities as "original issue discount securities," which
bear either no interest or interest at a rate which at the time of issuance is
below market rates. These securities will be sold at a substantial discount
below their principal amount. In the event that the maturity of an original
issue discount security is accelerated, the amount payable to the holder upon
acceleration will be determined in accordance with the terms of that security
and the indenture, but will be an amount less than the amount payable at the
stated maturity of the principal of the security. The prospectus supplement will
describe special federal income tax and other considerations relating to
original issue discount securities.

     The covenants contained in the indenture and the debt securities will not
protect holders in the event of a sudden decline in our creditworthiness that
might result from a recapitalization, restructuring, or other highly leveraged
transaction.

REGISTRATION AND TRANSFER

     Unless otherwise indicated in the prospectus supplement, we will issue each
series of debt securities in registered form only, without coupons and in
denominations of $1,000 or integral multiples thereof. Holders may present debt
securities in registered form for registration of transfer or exchange for other
debt securities of the same series at the corporate trust office of the trustee.

     No service charge will be made for any registration of transfer or exchange
of the debt securities except to cover any tax or other governmental charge
payable in connection with the registration of transfer or exchange.
                                        7
<PAGE>   9

PAYMENT AND PLACE OF PAYMENT

     We will pay principal of and any premium and interest on the debt
securities at the corporate trust office of the trustee. However, at our option,
we may pay any interest by check mailed to the holders of registered debt
securities at their registered addresses.

EVENTS OF DEFAULT

     The following are "events of default" under the indenture with respect to
any series of debt securities:

     -  default in the payment of any principal or premium when due;

     -  default in the payment of any interest when due, which continues for 30
        days;

     -  default in the deposit of any sinking fund payment when due;

     -  default in the performance of any other obligation contained in the
        indenture for the benefit of debt securities of that series, which
        continues for 60 days after written notice;

     -  default in the payment of other indebtedness at its stated maturity;

     -  acceleration of other indebtedness in a principal amount of $10,000,000
        or more, which is not annulled within 90 days after written notice;

     -  specified events in bankruptcy, insolvency or reorganization; and

     -  any other event of default provided with respect to debt securities of
        that series.

     If an event of default under the indenture occurs and continues for any
series of debt securities, the trustee or the holders of at least 25% in
aggregate principal amount of the outstanding securities of that series may
declare the principal amount, or any lesser amount provided for in the debt
securities of that series, to be due and payable immediately. After the trustee
or the holders have accelerated a series of debt securities, but before the
trustee has obtained a judgment or decree for payment of money due, the holders
of a majority in aggregate principal amount of outstanding debt securities of
that series may, under specified circumstances, rescind and annul the
acceleration.

     The holders of a majority in principal amount of the outstanding debt
securities of any series may waive an event of default with respect to that
series, except a default:

     -  in the payment of any amounts due and payable under the debt securities
        of that series; or

     -  in an obligation contained in, or a provision of, the indenture which
        cannot be modified under the terms of the indenture without the consent
        of each holder of outstanding debt securities of the affected series.

     The holders of a majority in principal amount of the outstanding debt
securities of a series may 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 debt securities of that series,
provided that this direction is not in conflict with any rule of law or the
indenture. Before proceeding to exercise any right or power under the indenture
at the direction of the holders, the trustee is entitled to receive from those
holders reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in complying with the direction.

     A holder of any debt security of any series will have the right to
institute a proceeding with respect to the indenture or for any remedy
thereunder, if:

     -  that holder previously gave written notice to the trustee of a
        continuing event of default with respect to debt securities of that
        series;

     -  the holders of not less than 25% in aggregate principal amount of the
        outstanding debt securities of that series also shall have made written
        request to the trustee to institute the proceeding as trustee and
        offered the trustee indemnity satisfactory to the trustee;
                                        8
<PAGE>   10

     -  the trustee shall have failed to institute the proceeding within 60
        days; and

     -  the trustee shall not have received from the holders of a majority in
        principal amount of the outstanding debt securities of that series a
        direction inconsistent with such request during that 60-day period.

     However, any holder of a debt security has the absolute, unconditional
right to institute suit for any defaulted payment after the due date for payment
under that debt security.

     We are required to furnish to the trustee annually a statement as to the
performance of our obligations under the indenture and as to any default in such
performance.

MODIFICATION AND WAIVER

     The indenture may be modified and amended by us and the trustee through a
supplemental indenture, with the consent of holders of at least a majority in
principal amount of each series of debt securities affected. However, without
the consent of each holder of any debt security affected, we may not amend or
modify any indenture to:

     -  change the stated maturity date of the principal, or any installment of
        principal of or interest on, any debt security;

     -  reduce the principal amount of, the rate of interest on, or any premium
        payable upon the redemption of any debt security;

     -  reduce the amount of principal of an original issue discount security
        payable upon acceleration of its maturity;

     -  change the place or currency of payment of principal of, or any premium
        or interest on, any debt security;

     -  impair the right to institute suit for the enforcement of any payment
        with respect to any debt security;

     -  reduce the percentage in principal amount of debt securities of any
        series, the consent of whose holders is required to modify or amend the
        indenture or to waive compliance with certain provisions of the
        indenture; or

     -  reduce the percentage in principal amount of debt securities of any
        series, the consent of whose holders is required to waive any past
        default.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     We may consolidate or merge with or into any other corporation, and we may
convey, transfer or lease all or substantially all of our assets to any
corporation, provided that:

     -  the resulting corporation, if other than us, is a corporation organized
        and existing under the laws of the United States of America or any U.S.
        state and assumes all of our obligations on the debt securities under
        the indenture;

     -  we are not, or any successor corporation is not, immediately after any
        consolidation or merger, in default under the indenture; and

     -  other specified conditions are met.

REGARDING THE TRUSTEE

     Bank One Trust Company, N.A. is the trustee under the indenture. We and our
subsidiaries maintain banking relations with affiliates of the trustee in the
ordinary course of business.

                                        9
<PAGE>   11

DEFEASANCE

     We may terminate or "defease" our obligations under the indenture of any
series of debt securities provided that:

     -  we deposit irrevocably with the trustee as trust funds in trust either
        an amount in U.S. dollars sufficient to pay the entire amount of the
        debt securities, or U.S. government obligations which, through the
        payment of interest, principal or premium, will provide an amount
        sufficient to pay the entire amount of the debt securities;

     -  we deliver an opinion of counsel that the holders of the debt securities
        of the series will have no federal income tax consequences as a result
        of the deposit and defeasance;

     -  no event of default or event which, with notice or lapse of time or
        both, would become an event of default under the indenture may exist or
        be caused by the defeasance;

     -  the defeasance shall not cause a default under any of our other
        agreements or instruments; and

     -  other specified conditions are met.

GOVERNING LAW

     The indenture is, and the debt securities will be, governed by and
construed in accordance with the laws of The Commonwealth of Massachusetts.

                               GLOBAL SECURITIES

     We may issue the debt securities in whole or in part in the form of one or
more fully registered global securities, each a "global security" that will be
deposited with, or on behalf of, a depository. Unless otherwise indicated in the
prospectus supplement, the depository will be The Depository Trust Company
("DTC") and the debt securities will be registered in the name of Cede & Co. or
another nominee of DTC.

     The specific terms of the depository arrangement with respect to any debt
securities will be described in the prospectus supplement. We anticipate that
the following provisions will apply to all depository arrangements.

     So long as the depository or its nominee is the holder of a global
security, the depository or the nominee will be considered the sole owner or
holder of the debt securities represented by the global security for all
purposes under the indenture. Except as set forth below, owners of beneficial
interests in a global security representing debt securities:

     -  will not be entitled to have the debt securities registered in their
        names;

     -  will not receive or be entitled to receive physical delivery of the debt
        securities in definitive form; and

     -  will not be considered the owners or holders of the debt securities
        under the indenture.

     Accordingly, each person owning a beneficial interest in a global security
must rely on the procedures of the depository and, if that person is not a
participant in the depository, on the procedures of the participant through
which that person owns its interest, to exercise any rights of a holder under
the indenture. We understand that, under existing industry practices, if we
request 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 indenture, the depository will authorize the participants
holding the relevant beneficial interest to give or take that action, and the
participants will authorize beneficial owners owning through them to give or
take (or direct the participants to give or take) that action.

     Payments of principal of or any premium and interest on debt securities
represented by a global security will be made to the depository or its nominee
as the registered holder of the global security
                                       10
<PAGE>   12

representing the debt securities. Neither NSTAR, the trustee for the debt
securities, any paying agent for the debt securities nor the securities
registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in a global security for the debt securities or for maintaining,
supervising or reviewing any records relating to those beneficial ownership
interests.

     Global debt securities may be exchanged for definitive debt securities only
if:

     -  the depository has notified us that it is unwilling or unable to
        continue as depository for the global debt security or has ceased to be
        a clearing agency registered under the Securities Exchange Act of 1934;

     -  there shall have occurred and be continuing an event of default with
        respect to the debt securities represented by the global debt security;
        or

     -  we decide, in our discretion, that the global debt security shall be
        exchangeable.

     Unless and until it is exchanged in whole or in part for debt securities in
definitive form in the manner described above, a global security may not be
transferred except as a whole by the depository to a nominee of the depository,
by a nominee of the depository to the depository or another nominee of the
depository, or by the depository or any such nominee to a successor of the
depository or a nominee of such successor.

BOOK-ENTRY ISSUANCE

     DTC has advised us that:

          DTC is a limited purpose trust company organized under the New York
     Banking Law, a "banking organization" within the meaning of the New York
     Banking Law, a member of the Federal Reserve System, a "clearing
     corporation" within the meaning of the New York Uniform Commercial Code,
     and a "clearing agency" registered pursuant to the provisions of Section
     17A of the Securities Exchange Act of 1934.

          DTC holds securities that its participants deposit with DTC. DTC also
     facilitates the settlement among participants of securities transactions,
     such as transfers and pledges, in deposited securities through electronic
     computerized book-entry changes in participants' accounts. This eliminates
     the need for physical movement of securities certificates. Participants
     include securities brokers and dealers, banks, trust companies, clearing
     corporations and other organizations. DTC is owned by a number of its
     participants and by the New York Stock Exchange, Inc., the American Stock
     Exchange, Inc. and the National Association of Securities Dealers, Inc.
     Access to the DTC system is also available to others such as securities
     brokers and dealers, banks and trust companies that clear through or
     maintain custodial relationships with direct participants, either directly
     or indirectly ("indirect participants"). The rules applicable to DTC and
     its participants are on file with the SEC.

          Purchases of debt securities within the DTC system must be made by or
     through direct participants, which will receive a credit for the debt
     securities on DTC's records. The ownership interest of each actual
     purchaser of each debt security (a "beneficial owner") is in turn recorded
     on the direct and indirect participants' records. DTC will maintain
     accounts showing the debt security holdings of its participants, and these
     participants will in turn maintain accounts showing the debt security
     holdings of their customers. Some of these customers may themselves be
     securities intermediaries holding debt securities for their customers.
     Thus, each beneficial owner of a book-entry debt security will hold that
     debt security indirectly through a hierarchy of intermediaries, with DTC at
     the "top" and the beneficial owner's own securities intermediary at the
     "bottom."

          Beneficial owners will not receive written confirmation from DTC of
     their purchases. Instead, beneficial owners are expected to receive written
     confirmations providing details of the transactions, as well as periodic
     statements of their holdings, from the direct or indirect participants
     through which the beneficial owners purchased the debt securities.
     Transfers of ownership interests in the debt
                                       11
<PAGE>   13

     securities are accomplished by entries made on the books of participants
     acting on behalf of beneficial owners. Beneficial owners will not receive
     certificates representing their ownership interests in the debt securities,
     except in the event that use of the book-entry system for the debt
     securities is discontinued.

          DTC has no knowledge of the actual beneficial owners of the debt
     securities. DTC's records reflect only the identity of the direct
     participants to whose accounts those debt securities are credited, which
     may or may not be the beneficial owners. The participants and indirect
     participants will remain responsible for keeping account of their holdings
     on behalf of their customers.

          Conveyance of notices and other communications by DTC to direct
     participants, by direct participants to indirect participants, and by
     direct participants and indirect participants to beneficial owners, and the
     voting rights of direct participants, indirect participants and beneficial
     owners, will be governed by arrangements among them, subject to any
     statutory or regulatory requirements as may be in effect from time to time.

          Redemption notices will be sent to Cede & Co. (or other DTC nominee)
     as the registered holder of the debt securities. If less than all of the
     debt securities are being redeemed, DTC's current practice is to determine
     by lot the amount of the interest of each direct participant to be
     redeemed.

          Although voting with respect to the debt securities is limited to the
     holders of record of the debt securities, in those instances in which a
     vote is required, neither DTC nor Cede & Co. (or other DTC nominee) will
     itself consent or vote with respect to the debt securities. Under its usual
     procedures, DTC will mail an omnibus proxy to the trustee as soon as
     possible after the record date. An omnibus proxy assigns Cede & Co.'s
     consenting or voting rights to those direct participants to whose accounts
     the debt securities are credited on the record date, who are identified in
     a listing attached to the omnibus proxy.

          Redemption proceeds and distribution payments on the debt securities
     will be made by NSTAR or the trustee to Cede & Co. (or other DTC nominee)
     as registered holder of the debt securities. DTC's practice is to credit
     direct participants' accounts on the relevant payment date in accordance
     with their respective holdings shown on DTC's records unless DTC has reason
     to believe that it will not receive payments on that payment date. Payments
     by participants to beneficial owners will be governed by standing
     instructions and customary practices and will be the responsibility of
     participants and not of DTC, the trustee or NSTAR, subject to any
     applicable statutory or regulatory requirements. Payment of redemption
     proceeds and distributions to DTC is the responsibility of NSTAR or the
     trustee, and disbursements of those payments to the beneficial owners is
     the responsibility of direct and indirect participants.

          DTC may discontinue providing its services as securities depository
     with respect to any of the debt securities at any time by giving reasonable
     notice to the trustee and us. Under these circumstances, in the event that
     a successor securities depository is not obtained, definitive certificates
     representing such debt securities are required to be printed and delivered.
     Additionally, we, at our option, may decide to discontinue use of the
     system of book-entry transfers through DTC (or a successor depository). In
     that event, definitive certificates for such debt securities will be
     printed and delivered.

     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that we believe to be reliable, but we assume no
responsibility for the accuracy thereof. Neither we nor the trustee has any
responsibility for the performance by DTC or its participants of their
respective obligations as described herein or under the rules and procedures
governing their respective operations.

                              PLAN OF DISTRIBUTION

     We may sell securities:

     -  to the public through a group of underwriters managed or co-managed by
        one or more underwriters;

     -  directly to purchasers.

     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 from time to time;

     -  at market prices prevailing at the time of sale;

     -  at prices related to those prevailing market prices; or

     -  at negotiated prices.

     Each prospectus supplement will describe the method of distribution of the
securities and any applicable restrictions.

     The prospectus supplement with respect to the securities of a particular
series will describe the terms of the offering of the securities, including the
following:

     -  the name or names of any agents or underwriters;

     -  the public offering or purchase price;

     -  any discounts and commissions to be allowed or paid to the agent or
        underwriters;

     -  all other items constituting underwriting compensation;

     -  any discounts and commissions to be allowed or paid to dealers; and

     -  any exchanges on which the securities will be listed.

     Only the agents or underwriters named in the prospectus supplement are
agents or underwriters in connection with the securities being offered.

     We may agree to enter into an agreement to indemnify the agents and the
several underwriters against certain civil liabilities, including liabilities
under the Securities Act, or to contribute to payments the agents or the
underwriters may be required to make.

     Certain of the underwriters and their associates and affiliates may be
customers of, have borrowing relationships with, engage in other transactions
with, and/or perform services, including investment banking services, for us or
one or more of our affiliates in the ordinary course of business.

     The debt securities will be new issues of securities and will have no
established trading market. Unless otherwise indicated in the prospectus
supplement relating to a specific issuance of debt securities, the debt
securities will not be listed on a national securities exchange or the Nasdaq
National Market. We can give no assurance as to the liquidity of or the
existence of trading markets for the debt securities.

ITEM 15.  INDEMNIFICATION OF TRUSTEES AND OFFICERS.

     NSTAR's declaration of trust provides that, to the extent legally
permissible, each of NSTAR's trustees and officers shall be indemnified by the
trust estate against any loss, liability or expense, including amounts paid in
satisfaction of judgments, in compromise or as fines and penalties, and counsel
fees, imposed upon or reasonably incurred by such person in connection with the
defense or disposition of any action, suit or other proceeding, whether civil or
criminal, in which such person may be involved or with which such person may be
threatened, while in office or thereafter, by reason of such person's being or
having been such a trustee or officer, except with respect to any matter as to
which such person shall have been adjudicated in such action, suit or proceeding
not to have acted in good faith in the reasonable belief that his or her action
was in the best interests of NSTAR; provided, however, that as to any matter
disposed of by a compromise payment by such trustee or officer, pursuant to a
consent decree or otherwise, no indemnification either for said payment or for
any other expense shall be provided unless such compromise shall be approved as
in the best interests of NSTAR, after notice that it involves such
indemnification, (i) by a disinterested majority of the trustees then in office,
or (ii) by a majority of the disinterested trustees then in office, provided
that there has been obtained an opinion in writing of independent legal counsel
to the effect that such trustee or officer appears to have acted in good faith
in the reasonable belief that his or her action was in the best interests of
NSTAR, or (iii) by the vote, at a meeting duly called and held, of the holders
of a majority of the shares outstanding and entitled to vote thereon, exclusive
of any shares owned by any interested trustee or officer.

     No trustee, officer or agent of NSTAR shall be liable except for acts or
failures to act which at the time would impose liability on him or her if the
trust were a Massachusetts business corporation and he or she were a director,
officer or agent thereof, respectively. In determining what he or she reasonably
believes to be in the best interests of NSTAR, a trustee may consider the
interests of NSTAR's employees, suppliers, creditors and customers, the economy
of the state, region and nation, community and societal considerations, and the
long-term and short-term interests of NSTAR, its subsidiaries and its
shareholders, including the possibility that these interests may best be served
by the continued independence of NSTAR. Notwithstanding any provision of law or
any provision contained in the declaration of trust, a trustee shall not be
liable to NSTAR or any shareholder for monetary damages for breach of fiduciary
duty as a trustee except with respect to any matter as to which such liability
is imposed by applicable law and he or she shall have been adjudicated (i) to
have breached his or her duty of loyalty to NSTAR or its shareholders, (ii) to
have acted not in good faith, or omitted to act in good faith, (iii) to have
knowingly violated the law or intentionally engaged in misconduct, or (iv) to
have derived any improper personal benefit from a transaction.

                                      II-1
<PAGE>   18

     In discharging his or her duties, a trustee or officer of NSTAR, when
acting in good faith, shall be fully protected in relying upon the books of
account of NSTAR or of another organization in which he or she serves as
contemplated by the indemnification provisions of the declaration of trust,
reports made to NSTAR or to such other organization by any of its officers or
employees or by counsel, accountants, appraisers or other experts or consultants
selected with reasonable care by the trustees or similar governing body of such
other organization, or upon other records of NSTAR or of such other
organization. The rights of indemnification provided in the declaration of trust
shall not be exclusive of or affect any other rights to which any trustee or
officer may be entitled and such rights shall inure to the benefit of his or her
successors, heirs, executors, administrators and other legal representatives. As
used in the relevant provisions of the declaration of trust, the terms "trustee"
and "officer" include persons who serve at the request of NSTAR as directors,
officers, or trustees of another organization in which NSTAR has any direct or
indirect interest as a shareholder, creditor or otherwise.

     Expenses, including counsel fees, reasonably incurred by any trustee or
officer with respect to the defense or disposition of any action, suit or
proceeding referred to in the indemnification provisions of the declaration of
trust may be advanced by NSTAR prior to the final disposition of such action,
suit or proceeding, upon receipt of an undertaking by or on behalf of the
recipient to repay such amount unless it is ultimately determined that he or she
is entitled to indemnification. Nothing contained in these provisions affects
any rights of indemnification to which NSTAR personnel other than trustees and
officers may be entitled by contract or otherwise under law. No trustees shall
be obligated to give any bond or other security for the performance of any of
his or her duties.

     For the undertaking with respect to indemnification, see Item 17 herein.

     The form or forms of debt securities with respect to each offering of debt
securities registered hereunder will be filed as an exhibit to a Current Report
on Form 8-K of NSTAR and will be incorporated herein by reference.

ITEM 17.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein; and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under

                                      II-2
<PAGE>   19

Item 15 above, or otherwise, the Registrant has been advised that in the opinion
of the SEC 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 the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by the controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     The Registrant hereby also 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 of 1933;

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

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

     provided, however, that paragraphs (1)(i) and 1(ii) shall 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 Registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference in this Registration Statement.

          (2)  That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

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

of such documents is specifically required by any provision of this Indenture
relating to such particular application or request, no additional certificate or
opinion need be furnished.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than certificates
provided pursuant to Section 10.7) shall include

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

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


                                       -7-

<PAGE>   13



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

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

Section 1.3  FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

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

         Any certificate or opinion of any officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such 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 1.4  ACTS OF HOLDERS.

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

                                       -8-

<PAGE>   14



for any purpose of this Indenture and (subject to Section 6.1) conclusive in
favor of the Trustee and the Company, if made in the manner provided in this
Section.

         (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 manner which the Trustee deems sufficient.

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

         (d) 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, the
Company in reliance thereon, whether or not notation of such action is made upon
such Security or such other Security.

         (e) The Depositary selected pursuant to subsection (16) of Section 3.1,
as a Holder, may appoint agents and otherwise authorize participants to give or
take any request, demand, authorization, direction, notice, consent, waiver or
other action which a Holder is entitled to give or take hereunder.

Section 1.5  NOTICES, ETC., TO TRUSTEE OR 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 the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         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 office
         specified in the first paragraph of this instrument or at any other
         address previously furnished in writing to the Trustee by the Company.

Section 1.6  NOTICE TO HOLDERS; WAIVER.

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

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

Section 1.7  CONFLICT WITH TRUST INDENTURE ACT.

         If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required provision shall
control. If any provision hereof limits, qualifies or conflicts with the duties
imposed by Section 318(c) of the Trust Indenture Act such imposed duties shall
control. If any provision of the Indenture limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern the Indenture, such provision of such Act shall control. If
any provision of the 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 the Indenture as such provision of such Act is so modified or
excluded, as the case may be.

Section 1.8  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

Section 1.9  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 1.10  SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 1.11  BENEFITS OF INDENTURE.

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

Section 1.12  GOVERNING LAW.

         This Indenture and the Securities shall be governed by and construed in
accordance with the laws of The Commonwealth of Massachusetts.

Section 1.13  LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue on the amount then payable for
the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be.

                                    ARTICLE 2

Indenture, and may have such letters, numbers or other marks of identification

<PAGE>   20



         If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
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 series. With respect to Securities of
a series constituting a medium term note program, such Board Resolution may
provide general terms or parameters for Securities of such series and may
provide that the specific terms of particular Securities of such series, and the
Persons authorized to determine such terms or parameters, may be determined in
accordance with or pursuant to the Company Order referred to in Section 3.3.

Section 3.2  DENOMINATIONS.

         The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 3.1. In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

Section 3.3  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities 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 attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities;
provided, that, with respect to Securities of a series constituting a medium
term note program, the Trustee shall authenticate and deliver Securities of such
series for original issue from time to time in the aggregate principal amount
established for such series pursuant to such procedures acceptable to the
Trustee and to such recipients as may be specified from time to time by a
Company Order. The maturity dates, original issue dates, interest rates and any
other terms of the Securities of such series shall be determined by or pursuant
to such Company Order and procedures. If provided for in such procedures, such
Company Order may authorize authentication and delivery pursuant to oral
instructions from the Company or its duly authorized agent, which instructions
shall be promptly confirmed in writing.

                                      -15-

<PAGE>   21



         If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 2.1 and 3.1, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 6.1) shall be
fully protected in relying upon, an Opinion of Counsel stating,

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

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

                  (c) that such Securities, when authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company, enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         reorganization and other laws of general applicability relating to or
         affecting the enforcement of creditors' rights and to general equity
         principles.

Notwithstanding that 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 would adversely affect the Trustee's own
rights, duties or immunities under the Securities and this Indenture or
otherwise in a manner which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 3.1 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the Company Order and Opinion of Counsel
otherwise required pursuant to the preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents have been
delivered at or prior to the time of authentication upon original issuance of
the first Security of such series to be issued.

         With respect to Securities of a series constituting a medium term note
program, if the form and general terms of the Securities of such series have
been established by or pursuant to one or more Board Resolutions or by an
indenture supplemental hereto, as permitted by Sections 2.1 and 3.1 in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 6.1) shall be fully protected in
relying upon, in addition to the foregoing documents and Opinion of Counsel, or
in lieu of clause (c) above, an Opinion of Counsel stating that the Securities
have been duly authorized by the Company and, when duly executed by the Company
and completed and authenticated by the Trustee in accordance with

                                      -16-

<PAGE>   22



the Indenture and issued, delivered and paid for in accordance with any
applicable distribution agreement, will have been duly issued under the
Indenture and will constitute valid and binding obligations of the Company,
enforceable in accordance with their terms, subject to bankruptcy, insolvency,
reorganization and other laws of general applicability relating to or affecting
the enforcement of creditors' rights and to general equity principles.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.9 together with a written statement (which
need not comply with Section 1.2 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

Section 3.4  TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order from the Company, 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, with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as evidenced
by their execution of such Securities.

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

Section 3.5  REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

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

         Upon surrender for registration of transfer of any Security of any
series at an office or agency of the Company in a Place of Payment designated by
the Company pursuant to Section 10.2 for that series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series of any authorized denominations and of a
like aggregate principal amount and tenor, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

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

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) 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 for
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 3.4, 9.6 or 11.7 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.3 and ending
at the close of business on the day of such mailing, or (ii) to

                                      -18-

<PAGE>   24



register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

         Notwithstanding the foregoing, any Global Security shall be
exchangeable pursuant to this Section 3.5 for Securities registered in the names
of Persons other than the Depositary for such Security or its nominee only if
(i) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or if any time such Depositary
ceases to be a clearing agency registered under the Securities Exchange Act of
1934, as amended, (ii) the Company executes and delivers to the Trustee a
Company Order that such Global Security shall be so exchangeable or (iii) there
shall have occurred and be continuing an Event of Default of which the Trustee
has been notified with respect to the Securities. Any Global Security that is
exchangeable pursuant to the preceding sentence shall be exchangeable for
Securities registered in such names as the Depositary shall direct in writing in
an aggregate principal amount equal to the principal amount of the Global
Security with like tenor and terms.

         Notwithstanding any other provision in this Indenture, a Global
Security may not be transferred except as a whole by the Depositary with respect
to such Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.

Section 3.6  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

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

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of any of them harmless, then, in the absence of notice to the Company
or the Trustee that such Security has been acquired by a bona fide purchaser,
the Company shall execute and upon its request the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Security, a new
Security of the same series and of like tenor and principal amount, and bearing
a number not contemporaneously outstanding.

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

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be

                                      -19-

<PAGE>   25



imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

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

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

Section 3.7  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Unless otherwise provided as contemplated by Section 3.1 with respect
to any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

         Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
entitled to such interest 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 Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date (as defined below) for the
         payment of such Defaulted Interest, which shall be fixed in the
         following manner. The Company shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Security
         of such series and the date of the proposed payment, and at the same
         time the Company shall deposit with the Trustee an amount of money
         equal to the aggregate amount proposed to be paid in respect of such
         Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a special record date (the "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

                                      -20-

<PAGE>   26



         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
         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.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been so mailed, such Defaulted
         Interest shall be paid to the Persons in whose names the Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on such Special Record Date and shall no
         longer be payable pursuant to the following clause (2).

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

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

Section 3.8  PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 3.7) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

Section 3.9  CANCELLATION.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold and all Securities so delivered shall be promptly
canceled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as

                                      -21-

<PAGE>   27



provided in this Section, except as expressly permitted by this Indenture. All
canceled Securities held by the Trustee shall be disposed of as directed by a
Company Order from the Company.

Section 3.10  COMPUTATION OF INTEREST.

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

                           SATISFACTION AND DISCHARGE

Section 4.1  SATISFACTION AND DISCHARGE OF INDENTURE.

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

                  (1)  either

                           (A) all Securities theretofore authenticated and
                  delivered (other than (i) Securities which have been
                  destroyed, lost or stolen and which have been replaced or paid
                  as provided in Section 3.6 and (ii) Securities for whose
                  payment money has theretofore been deposited in trust or
                  segregated and held in trust by the Company and thereafter
                  repaid to the Company or discharged from such trust, as
                  provided in Section 10.3) have been delivered to the Trustee
                  for cancellation; or

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

                                    (i)  have become due and payable, or

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

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

                  and the Company, in the case of (i), (ii) or (iii) above, has
                  deposited or caused to be deposited with the Trustee as trust
                  funds in trust for the purpose an amount sufficient to pay and
                  discharge the entire indebtedness on such Securities not
                  theretofore delivered to the Trustee for cancellation, for
                  principal (and premium, 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; and

                  (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 have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last

if any) and interest for whose payment such money has been deposited with or
received by the Trustee as contemplated by Section 4.1, Section 13.2 or Section
13.3.

         warranty of the Company in this Indenture (other than a covenant or
         warranty a default in whose performance or whose breach is elsewhere in
         this Section specifically dealt with or which has expressly been
         included in this Indenture solely for the benefit of series of
         Securities other than that series), and continuance of such default or
         breach for a period of 60 days after there has been given, by

         there may be issued or by which there may be secured or evidenced any
         Indebtedness for money borrowed by the Company including this
         Indenture, whether such Indebtedness now exists or shall hereafter be
         created, which default is in payment thereof at its stated maturity or

         Officer of the Trustee shall have actual knowledge of such default or
         (B) the Trustee shall have received written notice thereof from the
         Company, from any Holder, from the holder of

                                      -24-

         indenture or other instrument; or

                  (6) the entry by a court having jurisdiction in the premises
         of (A) a decree or order for relief in respect of the Company in an

         creditors, or the admission by the Company in writing of its inability
         to pay its debts generally as they become due, or the taking of
         corporate action by the Company in furtherance of any such action; or

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

Subject to the provisions of Section 6.1 hereof, the Trustee shall not be deemed
to have knowledge of an Event of Default hereunder (except for those described
in paragraphs (1) through (3) above) unless a Responsible Officer has received
written notice thereof.

Section 5.2  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
any of the Securities of that series are Original Issue Discount

                                      -25-

Securities, such portion of the principal amount of such Securities as may be
specified in the terms thereof) of all of 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 Holders), and upon any such declaration such principal
amount (or specified amount) 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 and its consequences if

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

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

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

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

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

         and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 5.13.

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

         Upon receipt by the Trustee of any declaration of acceleration, or
rescission and annulment thereof, with respect to Securities of a series all or
part of which is represented by a Global Security, the Trustee shall establish a
record date for determining Holders of Outstanding Securities of such series
entitled to join in such declaration of acceleration, or rescission and
annulment, as the case may be, which record date shall be at the close of
business on the day the Trustee receives such declaration of acceleration, or
rescission and annulment, as the case may be. The Holders on such record date,
or their duly designated

                                      -26-

<PAGE>   32



proxies, and only such persons, shall be entitled to join in such declaration of
acceleration, or rescission and annulment, as the case may be, whether or not
such Holders remain Holders after such record date; provided, that unless such
declaration of acceleration, or rescission and annulment, as the case may be,
shall have become effective by virtue of the requisite percentage having been
obtained prior to the day which is 90 days after such record date, such
declaration of acceleration, or rescission and annulment, as the case may be,
shall automatically and without further action by any Holder be canceled and of
no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy
of a Holder, from giving, after expiration of such 90-day period, a new
declaration of acceleration, or rescission or annulment thereof, as the case may
be, that is identical to a declaration of acceleration, or rescission or
annulment thereof, which has been canceled pursuant to the provision to the
preceding sentence, in which event a new record date shall be established
pursuant to the provision of this Section 5.2.

Section 5.3  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         The Company covenants that if

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

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof; or

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

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

         If 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, may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

                                      -27-

<PAGE>   33



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

Section 5.4  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
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 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 of
         principal (and premium, 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.

Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.7.

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

Section 5.5  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

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

Section 5.6  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,
if any) or interest, upon presentation of the Securities 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 under
         Section 6.7;

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

                  THIRD:  To the Company.

Section 5.7  LIMITATION ON SUITS.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

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

                  (2) the Holders of not less than 25% in principal amount of
         the 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;


                                      -29-

<PAGE>   35



                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity 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 any provision of this Indenture to
affect, disturb or prejudice the rights of any other of such Holders, or to
obtain or to seek to obtain priority or preference over any other of such
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all of such Holders.

Section 5.8  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
             INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 3.7) interest on such Security on the Stated Maturity or Maturities
expressed in such Security (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 5.9  RESTORATION OF RIGHTS AND REMEDIES.

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

Section 5.10  RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or

                                      -30-

<PAGE>   36



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

Section 5.11  DELAY OR OMISSION NOT WAIVER.

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

Section 5.12  CONTROL BY HOLDERS.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
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, nor subject the Trustee to a material risk
         of personal liability in respect of which the Trustee has not received
         reasonably satisfactory indemnification, and

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

         Upon receipt by the Trustee of any such direction with respect to
Securities of a series all or part of which is represented by a Global Security,
the Trustee shall establish a record date for determining Holders of outstanding
Securities of such series entitled to join in such direction, which record date
shall be at the close of business on the day the Trustee receives such
direction. The Holders on such record date, or their duly designated proxies,
and only such persons, shall be entitled to join in such direction, whether or
not such Holders remain Holders after such record date; provided, that unless
such majority in principal amount shall have been obtained prior to the day
which is 90 days after such record date, such direction shall automatically and
without further action by any Holder be canceled and of no further effect.
Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from
giving, after expiration of such 90-day period, a new direction identical to a
direction which has been canceled pursuant to the provisions to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 5.12.

Section 5.13  WAIVER OF PAST DEFAULTS.

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

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

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

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

Section 5.14  UNDERTAKING FOR COSTS.

         Each party to this Indenture agrees, 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,
suffered 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
Company, 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,
if any) or interest on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

Section 5.15  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

                                      -32-

<PAGE>   38



granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

                                    ARTICLE 6

                                   THE TRUSTEE

Section 6.1  CERTAIN DUTIES AND RESPONSIBILITIES.

         (a)  Except during the continuance of an Event of Default,

                  (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 require ments
         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.

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

         (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, determined as provided in Section 5.12, 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

                                      -33-

<PAGE>   39



         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.

Section 6.2  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 by mail to
all Holders of Securities of such series, as their names and addresses appear in
the Security Register, 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,
if any) or interest on any Security of such series or in the payment of any
sinking fund installment with respect to 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 or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of Securities of such series.
For the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

Section 6.3  CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 6.1:

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

                  (b) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order,

<PAGE>   40



         expressly provided herein, and any resolution of the Company Trustees
         may be sufficiently evidenced by a Board Resolution;

                  (c) 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;

                  (d) 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;

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

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

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

Section 6.4  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. The Trustee

Registrar or any other agent of the Company or of the Trustee, in its individual
or any other capacity, may become the owner or pledgee of Securities and,

         The Company agrees

                  (1) to pay to the Trustee from time to time reasonable

         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

Section 6.8  DISQUALIFICATION; CONFLICTING INTERESTS.

         (a) If the Trustee has or shall acquire any conflicting interest, as
defined in subsection (c) of this Section, with respect to the Securities of any
series, and if the default, as defined in subsection (c) of this Section to
which such conflicting interest relates has not been cured or duly waived or
otherwise eliminated before the end of 90 days after the Trustee ascertains that
it has such conflicting interest, the Trustee shall, within such 90-day period,
either eliminate such conflicting interest, except as otherwise provided in
subsection (f) below, or resign with respect to the Securities of that series in
the manner and with the effect hereinafter specified in this Article.

         (b) In the event that the Trustee shall fail to comply with the
provisions of subsection (a) of this Section with respect to the Securities of
any series, the Trustee shall, within 10 days after the expiration of such
90-day period, transmit by mail to all Holders of Securities of that series, as
their names and addresses appear in the Security Register, notice of such
failure.

         (c) For the purposes of this Section, the Trustee shall be deemed to
have a conflicting interest with respect to the Securities of any series if a
default with respect to the Securities of such series has occurred and is
continuing (but irrespective of any period of grace or requirement of notice),
and

                  (1) the Trustee is trustee under this Indenture with respect
         to the Outstanding Securities of any series other than that series or
         is trustee under another indenture under which any other securities, or
         certificates of interest or participation in any other securities, of
         the Company are outstanding, unless such other indenture is a
         collateral trust indenture under which the only collateral consists of
         Securities issued under this Indenture, provided that there shall be
         excluded from the operation of this paragraph, the Securities of any
         series other than that series or any indenture or indentures under
         which other securities, or certificates of interest or participation in
         other securities, of the Company are outstanding, if

                           (i) this Indenture and any such other indenture or
                  indentures (and all series of securities issuable thereunder)
                  are wholly unsecured and rank equally and such other indenture
                  or indentures (and such series) are qualified or will be
                  hereafter qualified under the Trust Indenture Act, unless the
                  Commission shall have found and declared by order pursuant to
                  Section 305(b) or Section 307(c) of the Trust Indenture Act
                  that differences exist between the provisions of this
                  Indenture (or such series) and the provisions of such other
                  indenture or indentures (or such series) which are so likely
                  to involve a material conflict of interest as to make it
                  necessary in the public interest or for the protection of
                  investors to disqualify the Trustee from acting as such under
                  this Indenture with respect to the Securities of that series
                  and such other series or under any other indenture or
                  indentures, or

                                      -37-


<PAGE>   43



                           (ii) the Company shall have sustained the burden of
                  proving on application to the Commission and after opportunity
                  for hearing thereon that trusteeship under this Indenture with
                  respect to the Securities of that series and such other series
                  or such other indenture or indentures is not so likely to
                  involve a material conflict of interest as to make it
                  necessary in the public interest or for the protection of
                  investors to disqualify such Trustee from acting as such under
                  this Indenture with respect to the Securities of that series
                  or such other series or under such other indenture or
                  indentures;

                  (2) the Trustee or any of its directors or executive officers

         or indirectly controlled by or is under direct or indirect common
         control with the Company or an underwriter for the Company;

                  (4) the Trustee or any of its directors or executive officers
         is a director, officer, partner, employee, appointee or representative
         of the Company, or of an underwriter (other than the Trustee itself)
         for the Company who is currently engaged in the business of
         underwriting, except that (i) one individual may be a director or an
         executive officer, or both, of the Trustee and a director or an
         executive officer, or both, of the Company but may not be at the same
         time an executive officer of both the Trustee and the Company; (ii) if
         and so long as the number of directors of the Trustee in office is more
         than nine, one additional individual may be a director or an executive
         officer, or both, of the Trustee and a director of the Company; and
         (iii) the Trustee may be designated by the Company or by any
         underwriter for the Company to act in the capacity of transfer agent,
         registrar, custodian, paying agent, fiscal agent, escrow agent or
         depositary, or in any other similar capacity, or, subject to the
         provisions of paragraph (1) of this subsection, to act as trustee,
         whether under an indenture or otherwise;

                  (5) 10% or more of the voting securities of the Trustee is
         beneficially owned either by the Company or by any director, partner or
         executive officer thereof, or 20% or more of such voting securities is
         beneficially owned, collectively, by any two or more of such persons;
         or 10% or more of the voting securities of the Trustee is beneficially
         owned either by an underwriter for the Company or by any director,
         partner or executive officer thereof, or is beneficially owned,
         collectively, by any two or more such persons;

                  (6) the Trustee is the beneficial owner of, or holds as
         collateral security for an obligation which is in default (as defined
         below), (i) 5% or more of the voting securities, or 10% or more of any
         other class of security, of the Company, not including the Securities
         issued under this Indenture and securities issued under any

                                      -38-


<PAGE>   44



         other indenture under which the Trustee is also trustee, or (ii) 10% or
         more of any class of security of an underwriter for the Company;

                  (7) the Trustee is the beneficial owner of, or holds as

                  (8) the Trustee is the beneficial owner of, or holds as
         collateral security for an obligation which is in default (as defined
         below), 10% or more of any class of security of any person who, to the
         knowledge of the Trustee, owns 50% or more of the voting securities of
         the Company;

                  (9) the Trustee owns, on the date of default upon the
         Securities (but exclusive of any period of grace or requirement of
         notice) or any anniversary of such default while such default upon the
         Securities remains outstanding, in the capacity of executor,
         administrator, testamentary or inter vivos trustee, guardian, committee
         or conservator, or in any other similar capacity, an aggregate of 25%
         or more of the voting securities or of any class of security, of any
         person, the beneficial ownership of a specified percentage of which
         would have constituted a conflicting interest under paragraph (6), (7)
         or (8) of this subsection. As to any such securities of which the
         Trustee acquired ownership through becoming executor, administrator or
         testamentary trustee of an estate which included them, the provisions
         of the preceding sentence shall not apply for a period of two years
         from the date of such acquisition, to the extent that such securities
         included in such estate do not exceed 25% of such voting securities or
         25% of any such class of security. Promptly after the date of any such
         default upon the Securities and annually in each succeeding year that
         the Securities remain in default, the Trustee shall make a check of its
         holdings of such securities in any of the above-mentioned capacities as
         of such date. If the Company fails to make payment in full of the
         principal of (or premium, if any) or interest on any of the Securities
         when and as the same becomes due and payable, and such failure
         continues for 30 days thereafter, the Trustee shall make a prompt check
         of its holdings of such securities in any of the above-mentioned
         capacities as of the date of the expiration of such 30-day period, and
         after such date, notwithstanding the foregoing provisions of this
         paragraph, all such securities so held by the Trustee, with sole or
         joint control over such securities vested in it, shall, but only so
         long as such failure shall continue, be considered as though
         beneficially owned by the Trustee for the purposes of paragraphs (6),
         (7) and (8) of this subsection; or

                  (10) except under the circumstances described in paragraphs
         (1), (3), (4), (5) or (6) of Section 6.13(b), the Trustee shall be or
         shall become a creditor of the Company.

         For purposes of paragraph (1) of this subsection, and of Sections 5.12
and 5.13 of this Indenture, the term "series of securities" or "series" means a
series, class or group of securities issuable under an indenture pursuant to
whose terms holders of one such series may vote to direct the Trustee, or
otherwise take action pursuant to a vote of such holders, separately from
holders of another such series, provided, that "series of securities" or
"series" shall not include any series of Securities issuable under the Indenture
if all such series rank equally and are wholly unsecured.

         The specification of percentages in paragraphs (5) to (9), inclusive,
of this subsection shall not be construed as indicating that the ownership of
such percentages of the securities of a person is or is not necessary or
sufficient to constitute direct or indirect control for the purposes of
paragraph (3) or (7) of this subsection.

         For the purposes of paragraphs (6), (7), (8) and (9) of this subsection
only, (i) the terms "security" and "securities" shall include only such
securities as are generally known as corporate securities, but shall not include
any note or other evidence of indebtedness issued to evidence an obligation to
repay moneys lent to a person by one or more banks, trust companies or banking
firms, or any certificate of interest or participation in any such note or
evidence of indebtedness; (ii) an obligation shall be deemed to be "in default"
when a default in payment of principal shall have continued for 30 days or more
and shall not have been cured; and (iii) the Trustee shall not be deemed to be
the owner or holder of (A) any security which it holds as collateral security,
as trustee or otherwise, for any obligation which is not in default as defined
in clause (ii) above, or (B) any security which it holds as collateral security
under this Indenture, irrespective of any default hereunder, or (C) any security
which it holds as agent for collection, or as custodian, escrow agent or
depositary, or in any similar representative capacity.

         (d) For the purposes of this Section:

                  (1) The term "underwriter", when used with reference to the
         Company, means every person who, within one year prior to the time as
         of which the determination is made, has purchased from the Company with
         a view to, or has offered or sold for the Company in connection with,
         the distribution of any security of the Company outstanding at such
         time, or has participated or has had a direct or indirect participation
         in any such undertaking, or has participated or has had a participation
         in the direct or indirect underwriting of any such undertaking, but
         such term shall not include a person whose interest was limited to a
         commission from an underwriter or dealer not in excess of the usual and
         customary distributors' or sellers' commission.

                  (2) The term "director" means any director of a corporation or
         any individual performing similar functions with respect to any
         organization, whether incorporated or unincorporated.

         partnership, an association, a joint-stock company, a trust, an
         unincorporated organization or a government or political subdivision
         thereof. As used in this paragraph, the term "trust" shall include only
         a trust where the interest or interests of the beneficiary or
         beneficiaries are evidenced by a security.

                  (4) The term "voting security" means any security presently
         entitling the owner or holder thereof to vote in the direction or
         management of the affairs of a person, or any security issued under or
         pursuant to any trust, agreement or arrangement whereby a trustee or
         trustees or agent or agents for the owner or holder of such security
         are presently entitled to vote in the direction or management of the
         affairs of a person.

                  (5) The term "Company" means any obligor upon the Securities.

                  (6) The term "executive officer" means the president, every

         or unincorporated, but shall not include the chairman of the board of
         directors.

         (e) The percentages of voting securities and other securities specified
in this Section shall be calculated in accordance with the following provisions:

                  (1) A specified percentage of the voting securities of the
         Trustee, the Company or any other person referred to in this Section
         (each of whom is referred to as a "person" in this paragraph) means
         such amount of the outstanding voting securities of such person as
         entitles the holder or holders thereof to cast such specified
         percentage of the aggregate votes which the holders of all the
         outstanding voting securities of such person are entitled to cast in
         the direction or management of the affairs of such person.

                  (2) A specified percentage of a class of securities of a
         person means such percentage of the aggregate amount of securities of
         the class outstanding.

                  (3) The term "amount", when used in regard to securities,
         means the principal amount if relating to evidences of indebtedness,
         the number of shares if relating to capital shares and the number of
         units if relating to any other kind of security.

                  (4) The term "outstanding" means issued and not held by or for
         the account of the issuer. The following securities shall not be deemed
         outstanding within the meaning of this definition:

                           (i) securities of an issuer held in a sinking fund
                  relating to securities of the issuer of the same class;

                                      -41-


<PAGE>   47



                           (ii) securities of an issuer held in a sinking fund
                  relating to another class of securities of the issuer, if the
                  obligation evidenced by such other class of securities is not
                  in default as to principal or interest or otherwise;

                           (iii) securities pledged by the issuer thereof as
                  security for an obligation of the issuer not in default as to
                  principal or interest or otherwise; and

                           (iv) securities held in escrow if placed in escrow by
                  the issuer thereof;

         PROVIDED, HOWEVER, that any voting securities of an issuer shall be
         deemed outstanding if any person other than the issuer is entitled to
         exercise the voting rights thereof.

                  (5) A security shall be deemed to be of the same class as
         another security if both securities confer upon the holder or holders
         thereof substantially the same rights and privileges; PROVIDED,
         HOWEVER, that, in the case of secured evidences of indebtedness, all of
         which are issued under a single indenture, differences in the interest
         rates or maturity dates of various series thereof shall not be deemed
         sufficient to constitute such series different classes and PROVIDED,
         FURTHER, that, in the case of unsecured evidences or indebtedness,
         differences in the interest rates or maturity dates thereof shall not
         be deemed sufficient to constitute them securities of different
         classes, whether or not they are issued under a single indenture.

         (f) Except in the case of a default in the payment of the principal of
or interest on any Security or in the payment of any sinking or purchase fund
installment, the Trustee shall not be required to resign as provided by
subsection (a) of this Section if the Trustee shall have sustained the burden of
proving, on application to the Commission and after opportunity for hearing
thereon, that

                  (1) the default under this Indenture may be cured or waived
         during a reasonable period and under the procedures described in such
         application, and

                  (2) a stay of the Trustees' duty to resign will not be
         inconsistent with the interest of holders of the Securities. The filing
         of such an application shall automatically stay the performance of the
         duty to resign until the Commission orders otherwise.

Section 6.9  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000 and subject to supervision or examination by Federal or
State authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority,

                                      -42-


<PAGE>   48



then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

Section 6.10  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (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 6.11.

         (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 the
instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

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

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

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

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

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

         (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 by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

Section 6.11  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

         (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

                                      -44-


<PAGE>   50



successor Trustee with respect to the Securities of one or more series shall
execute and deliver an indenture supplemental hereto wherein each successor
Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and, upon
the execution and delivery of such supplemental indenture, the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall 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) and (b) of this Section, 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 6.12  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

                                      -45-


<PAGE>   51



authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

Section 6.13  PREFERENTIAL COLLECTION OF CLAIMS.

         (a) Subject to subsection (b) of this Section, if the Trustee shall be
or shall become a creditor, directly or indirectly, secured or unsecured, of the
Company within three months prior to a default, as defined in subsection (c) of
this Section, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the
Securities and the holders of other indenture securities, as defined in
subsection (c) of this Section:

                  (1) an amount equal to any and all reductions in the amount
         due and owing upon any claim as such creditor in respect of principal
         or interest, effected after the beginning of such three-month period
         and valid as against the Company and its other creditors, except any
         such reduction resulting from the receipt or disposition of any
         property described in paragraph (2) of this subsection, or from the
         exercise of any right of set-off which the Trustee could have exercised
         if a petition in bankruptcy had been filed by or against the Company
         upon the date of such default; and

                  (2) all property received by the Trustee in respect of any
         claims as such creditor, either as security therefor, or in
         satisfaction or composition thereof, or otherwise, after the beginning
         of such three-month period, or an amount equal to the proceeds of any
         such property, if disposed of, SUBJECT, HOWEVER, to the rights, if any,
         of the Company and its other creditors in such property or such
         proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

                  (A) to retain for its own account (i) payments made on account
         of any such claim by any Person (other than the Company) who is liable
         thereon, and (ii) the proceeds of the bona fide sale of any such claim
         by the Trustee to a third Person, and (iii) distributions made in cash,
         securities or other property in respect of claims filed against the
         Company in bankruptcy or receivership or in proceedings for
         reorganization pursuant to the Federal Bankruptcy Act or applicable
         State law;

                  (B) to realize, for its own account, upon any property held by
         it as security for any such claim, if such property was so held prior
         to the beginning of such three-month period;

                  (C) to realize, for its own account, but only to the extent of
         the claim hereinafter mentioned, upon any property held by it as
         security for any such claim, if such claim was created after the
         beginning of such three-month period and such property was received as
         security therefor simultaneously with the creation thereof, and if the
         Trustee

                                      -46-


<PAGE>   52



         shall sustain the burden of proving that at the time such property was
         so received the Trustee had no reasonable cause to believe that a
         default, as defined in subsection (c) of this Section, would occur
         within three months; or

                  (D) to receive payment on any claim referred to in paragraph
         (B) or (C), against the release of any property held as security for
         such claim as provided in paragraph (B) or (C), as the case may be, to
         the extent of the fair value of such property.

         For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such three-month period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any preexisting claim of the Trustee as such creditor, such claim shall have the
same status as such preexisting claim.

         If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned among
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law, the same percentage of their respective
claims, calculated before crediting to the claim of the Trustee anything on
account of the receipt by it from the Company of the funds and property in such
special account and before crediting to the respective claims of the Trustee and
the Holders and the holders of other indenture securities dividends on claims
filed against the Company in bankruptcy or receivership or in proceedings for
reorganization pursuant to the Federal Bankruptcy Act or applicable State law,
but after crediting thereon receipts on account of the indebtedness represented
by their respective claims from all sources other than from such dividends and
from the funds and property so held in such special account. As used in this
paragraph, with respect to any claim, the term "dividends" shall include any
distribution with respect to such claim, in bankruptcy or receivership or
proceedings for reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, whether such distribution is made in cash, securities or
other property, but shall not include any such distribution with respect to the
secured portion, if any, of such claim. The court in which such bankruptcy,
receivership or proceedings for reorganization are pending shall have
jurisdiction (i) to apportion among the Trustee, the Holders and the holders of
other indenture securities, in accordance with the provisions of this paragraph,
the funds and property held in such special account and proceeds thereof, or
(ii) in lieu of such apportionment, in whole or in part, to give to the
provisions of this paragraph due consideration in determining the fairness of
the distributions to be made to the Trustee and the Holders and the holders of
other indenture securities with respect to their respective claims, in which
event it shall not be necessary to

                                      -47-


<PAGE>   53



liquidate or to appraise the value of any securities or other property held in
such special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claims, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

         Any Trustee which has resigned or been removed after the beginning of
such three-month period shall be subject to the provisions of this subsection as
though such resignation or removal had not occurred. If any Trustee has resigned
or been removed prior to the beginning of such three-month period, it shall be
subject to the provisions of this subsection if and only if the following
conditions exist:

                  (i) the receipt of property or reduction of claim, which would
         have given rise to the obligation to account, if such Trustee had
         continued as Trustee, occurred after the beginning of such three-month
         period; and

                  (ii) such receipt of property or reduction of claim occurred
         within three months after such resignation or removal.

In any case commenced under the Bankruptcy Act of July 1, 1898, or any amendment
thereto enacted prior to November 6, 1978, all references to periods of three
months herein shall be deemed to be references to periods of four months.

         (b) There shall be excluded from the operation of subsection (a) of
this Section a creditor relationship arising from:

                  (1) the ownership or acquisition of securities issued under
         any indenture, or any security or securities having a maturity of one
         year or more at the time of acquisition by the Trustee;

                  (2) advances authorized by a receivership or bankruptcy court
         of competent jurisdiction or by this Indenture, for the purpose of
         preserving any property which shall at any time be subject to the lien
         of this Indenture or of discharging tax liens or other prior liens or
         encumbrances thereon, if notice of such advances and of the
         circumstances surrounding the making thereof is given to the Holders at
         the time and in the manner provided in this Indenture;

                  (3) disbursements made in the ordinary course of business in
         the capacity of trustee under an indenture, transfer agent, registrar,
         custodian, paying agent, fiscal agent or depositary, or other similar
         capacity;

                  (4) an indebtedness created as a result of services rendered
         or premises rented; or an indebtedness created as a result of goods or
         securities sold in a cash transaction, as defined in subsection (c) of
         this Section;

                                      -48-


<PAGE>   54



                  (5) the ownership of stock or of other securities of a
         corporation organized under the provisions of Section 25(a) of the
         Federal Reserve Act, as amended, which is directly or indirectly a
         creditor of the Company; or

                  (6) the acquisition, ownership, acceptance or negotiation of
         any drafts, bills of exchange, acceptances or obligations which fall
         within the classification of self-liquidating paper, as defined in
         subsection (c) of this Section.

         (c) For the purposes of this Section only:

                  (1) the term "default" means any failure to make payment in
         full of the principal of or interest on any of the Securities or upon
         the other indenture securities when and as such principal or interest
         becomes due and payable;

                  (2) the term "other indenture securities" means securities
         upon which the Company is an obligor outstanding under any other
         indenture (i) under which the Trustee is also trustee, (ii) which
         contains provisions substantially similar to the provisions of this
         Section, and (iii) under which a default exists at the time of the
         apportionment of the funds and property held in such special account;

                  (3) the term "cash transaction" means any transaction in which
         full payment for goods or securities sold is made within seven days
         after delivery of the goods or securities in currency or in checks or
         other orders drawn upon banks or bankers and payable upon demand;

                  (4) the term "self-liquidating paper" means any draft, bill of
         exchange, acceptance or obligation which is made, drawn, negotiated or

         merchandise and which is secured by documents evidencing title to,
         possession of, or a lien upon, the goods, wares or merchandise or the
         receivables or proceeds arising from the sale of the goods, wares or
         merchandise previously constituting the security, provided the security
         is received by the Trustee simultaneously with the creation of the
         creditor relationship with the Company arising from the making,
         drawing, negotiating or incurring of the draft, bill of exchange,
         acceptance or obligation;

                  (5) the term "Company" means any obligor upon the Securities;

Section 6.14  APPOINTMENT OF AUTHENTICATING AGENT.

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

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

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and the Company, and the Trustee shall terminate any such
agency promptly upon request by 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, upon request of the Company, shall
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall mail written notice of such appointment by first-class mail,
postage prepaid, to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, as their names and

                                      -50-


<PAGE>   56



addresses appear in the Security Register. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

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

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

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

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

Section 7.1  COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

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

                  (a) semi-annually (at intervals of not more than six months),
         not later than 15 days after each Regular Record Date (or, if there is
         no Regular Record Date relating to a series, semi-annually on dates set
         forth in the Board Resolution or supplemental indenture with respect to
         such series), a list, in such form as the Trustee may reasonably
         require, of the names and addresses of the Holders as of such date, and


                                      -51-


<PAGE>   57



                  (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;

EXCLUDING from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.

Section 7.2  PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

         (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.1 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 7.1 upon receipt of a new list so furnished.

         (b) If three or more Holders (herein referred to as "applicants") apply
in writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants desire to communicate with other Holders with respect to their rights
under this Indenture or under the Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit,
then the Trustee shall, within five business days after the receipt of such
application, at its election, either

                  (i) afford such applicants access to the information preserved
         at the time by the Trustee in accordance with Section 7.2(a), or

                  (ii) inform such applicants as to the approximate number of
         Holders whose names and addresses appear in the information preserved
         at the time by the Trustee in accordance with Section 7.2(a), and as to
         the approximate cost of mailing to such Holders the form of proxy or
         other communication, if any, specified in such application.

         If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appear in the information preserved
at the time by the Trustee in accordance with Section 7.2(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the

                                      -52-

                                    COVENANTS

Section 10.1  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

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

Section 10.2  MAINTENANCE OF OFFICE OR AGENCY.

         The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; PROVIDED, HOWEVER, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

Section 10.3  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 Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of (and
premium, if any) or interest

                                      -60-


<PAGE>   66



on any Securities of that series, deposit with a Paying Agent a sum sufficient
to pay the principal (and premium, 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 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 or the Company to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

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

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

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

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

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company in trust for the payment of the principal of (and premium, if
any) or interest on any Security of any series, and remaining unclaimed for two
years after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on Company Request of the Company or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to
the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on

repaid to the Company.

         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.

         The Company will cause all 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
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

Section 10.6  PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company will pay or discharge or cause to be paid or discharged,

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 10.5 and 10.6 with respect to
the Securities of any series if before the time for such compliance the Holders
of at least a majority in principal amount of the Outstanding Securities of such
series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

         The Company may set a record date for purposes of determining the
identity of Holders of Securities entitled to waive compliance pursuant to this
Section. Such record date shall be the later of (i) thirty days prior to the
first solicitation of such waiver or (ii) the date of the most recent list of
Holders furnished to the Trustee prior to such solicitation pursuant to Section

Section 11.2  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution. In case of any redemption at the election of the Company
of less than all the Securities of like tenor of any series, the Company shall,
at least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date 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

<PAGE>   69



         If less than all the Securities of like tenor of any series 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 like tenor of such series 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 such Securities of a denomination larger than the
minimum authorized denomination for such Securities.

         The Trustee shall promptly notify the Company 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 Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

Section 11.4  NOTICE OF REDEMPTION.

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

         All notices of redemption shall state:

         (1)  the Redemption Date,

         (2)  the Redemption Price,

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

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

         (5) the place or places where such Securities are to be surrendered for
payment of the Redemption Price, and

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

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

Section 11.5  DEPOSIT OF REDEMPTION PRICE.

         At least one Business Day 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, the Company shall segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date.

Section 11.6  SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and, from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; PROVIDED, HOWEVER, that installments of interest 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 3.7.

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

Section 11.7  SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by the 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 and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                  SINKING FUNDS

Section 12.1  APPLICABILITY OF ARTICLE.

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

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

Section 12.2  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

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

Section 12.3  REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 12.2 and will also deliver to the Trustee any such
Securities. Not less than 30 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 11.3 and cause notice of the
redemption thereof to be given in the name of and at the expense of the

                                      -66-


<PAGE>   72



Company in the manner provided in Section 11.4. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 11.6 and 11.7.

                                   ARTICLE 13

Section 13.1  APPLICABILITY OF ARTICLE; COMPANY'S OPTION TO EFFECT DEFEASANCE OR
COVENANT DEFEASANCE.

         If pursuant to Section 3.1 provision is made for either or both of (a)
defeasance of the Securities of a series under Section 13.2 or (b) covenant
defeasance of the Securities of a series under Section 13.3, then the provisions
of such Section or Sections, as the case may be, together with the other
provisions of this Article Thirteen, shall be applicable to the Securities of
such series, and the Company may at its option by or pursuant to a Board
Resolution, at any time, with respect to the Securities of such series, elect to
have either Section 13.2 (if applic able) or Section 13.3 (if applicable) be
applied to the Outstanding Securities of such series upon compliance with the
conditions set forth below in this Article Thirteen.

Section 13.2  DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of the option set forth in Section 13.1
applicable to this Section, the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of such series
on the date the conditions set forth below 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 the
Outstanding Securities of such series and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of Outstanding Securities of such series to receive, solely from the
trust fund described in Section 13.4 and as more fully set forth in such
Section, payments in respect of the principal of (and premium, if any) and
interest on such Securities when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 3.4, 3.5, 3.6, 10.2

series issued on registration of transfer or exchange and (D) this Article
Thirteen. Subject to compliance with this Article Thirteen, the Company may
exercise its option under this Section 13.2 notwithstanding the prior exercise
of its option under Section 13.3 with respect to the Securities of such series.

Section 13.3  COVENANT DEFEASANCE.

applicable to this Section, the Company shall be released from its obligations
under Sections 8.1(3), 10.5, 10.6 and 10.7 (and the failure to comply with any
such provisions shall not constitute a default or Event of Default under Section
5.1), and the occurrence of any event described in Section 5.1(4) shall not
constitute a default or Event of Default hereunder, with respect to the
Outstanding Securities of such series on and after the date the conditions set

purpose, such covenant defeasance means that, with respect to the Outstanding
Securities of such series, 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 with respect to it, whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or by reason of any reference in

payment of principal of or interest on the U.S. Government Obligation evidenced
by such depository receipt.

         (b) (i) No Event of Default or event which with notice or lapse of time
or both would become an Event of Default with respect to the Securities of such

referred to in subparagraph (a) above and (y) the Company shall provide to the
Trustee an Opinion of Counsel (which shall be nationally recognized counsel
experienced in bankruptcy matters) satisfactory to the Trustee to the effect
that no payments pursuant to the letter of credit to be made for the benefit of
the Holders of the Outstanding Securities to be defeased hereunder would be
subject to recapture, as a preference or otherwise, by any trustee in bankruptcy
of the Company, then this condition shall be satisfied without regard to the
period of time referred to in subsection (ii) above.

         (c) Such defeasance or covenant defeasance shall not cause the Trustee
for the Securities of such series to have a conflicting interest as defined in
Section 6.8 and for purposes of the Trust Indenture Act with respect to any
securities of the Company.

         (d) Such defeasance or covenant defeasance shall not result in a breach

applicable Federal income tax law, in either case to the effect that, and based
thereon such opinion shall confirm that, the Holders of the Outstanding
Securities of such series 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.

         (g) In the case of an election under Section 13.3, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of the Outstanding Securities of such series 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.

         (h) Such defeasance or covenant defeasance shall be effected in
compliance with any additional terms, conditions or limitations which may be
imposed on the Company in connection therewith pursuant to Section 3.1.

         (i) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the defeasance under Section 13.2 or
the covenant defeasance under Section 13.3, as the case may be, have been
complied with.

Section 13.5  DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 10.3, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee, collectively, for purposes of
this Section 13.5, the "Trustee") pursuant to Section 13.4 in respect of the
Outstanding Securities of such series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own paying agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due

law.

respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities of such series.

         Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 13.4 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof

defeasance.

     Re:  NSTAR -- $500,000,000
          aggregate amount of Securities
          ------------------------------

Ladies and Gentlemen:

     You have asked our opinion concerning the proposed issue by NSTAR (the
"Company") of unsecured debt securities (the "Securities"), to be issued in one
or more series under the Indenture between the Company and Bank One Trust
Company, N.A., as trustee (the "Indenture Trustee"), dated as of January 12,
2000 (the "Indenture"), such Securities to be issued at an aggregate initial
offering price not to exceed $500,000,000.

     We have acted as counsel for the Company in connection with the proposed
issue and sale of the Securities. We are familiar with the proceedings taken by
the Company in respect thereof and have examined originals or certified or
attested copies of such certificates, records and documents as we have deemed
necessary for the purposes of this opinion.

     Basing our opinion on the foregoing, we are of the opinion that:

     (1) when the Registration Statement relating to the Securities filed with
     the Securities and Exchange Commission under the Securities Act of 1933, as
     amended, has been declared effective, no further authorization, consent, or
     approval by any regulatory authority will be required for the valid
     issuance and sale of the Securities (except under the so-called "blue sky"
     or securities laws of the several states, as to the applicability of which
     we express no opinion);

     (2) when the Trustees of the Company or a committee designated thereby has
     determined the price and other terms and conditions relating to the issue
     and

NSTAR                                  -2-                   January 14, 2000


     sale of the Securities, the Securities will have been duly authorized by
     the Company;

     (3) upon the execution and filing with the Indenture Trustee of the proper
     papers, the Securities will be issuable under the terms of the Indenture;
     and

     (4) upon the execution, authentication and delivery of the Notes against
     payment therefor in accordance with the authorizations referred to in
     paragraphs (1), (2) and (3) above and in accordance with the Indenture, the
     Securities will be valid and legally binding obligations of the Company and
     the Securities will be entitled to the benefits of the Indenture together
     with other series of Securities (as defined in the Indenture) which may
     hereafter be issued thereunder pursuant to the terms thereof, subject to
     (i) bankruptcy, insolvency, reorganization, moratorium and similar laws
     affecting the rights and remedies of creditors and (ii) general principles
     of equity, regardless of whether applied in proceedings in equity or law.

     We understand that this opinion is to be used in connection with the
Company's Registration Statement relating to the Securities to be filed under
the Securities Act of 1933, as amended. We consent to the filing of this opinion
with and as part of said Registration Statement and the use of our name therein
and in the related Prospectus under the caption "Validity of Securities."


                                                     Very truly yours,

                  BANK ONE TRUST COMPANY, NATIONAL ASSOCIATION


FIRST. The title of this Association shall be BANK ONE TRUST COMPANY, NATIONAL
ASSOCIATION.

SECOND. The main office of the Association shall be in the City of Columbus,
County of Franklin, State of Ohio.

The business of the Association will be limited to the fiduciary powers and the
support of activities incidental to the exercise of those powers. The
Association will not expand or alter its business beyond that stated in this
article without the prior approval of the Comptroller of the Currency.

THIRD. The Board of Directors of this Association shall consist of not less than
five nor more than twenty-five persons, the exact number to be fixed and
determined from time to time by resolution of a majority of the full Board of
Directors or by resolution of a majority of the shareholders at any annual or
special meeting thereof. Each director shall own common or preferred stock of
the Association, or of a holding company owning the Association, with an
aggregate par, fair market or equity value of not less than $1,000, as of either
(i) the date of purchase, (ii) the date the person became a director, or (iii)
the date of that person's most recent election to the Board of Directors,
whichever is more recent. Any combination of common or preferred stock of the
Association or holding company may be used.

Any vacancy in the Board of Directors may be filled by action of a majority of
the remaining directors between meetings of shareholders. The Board of Directors
may not increase the number of directors between meetings of shareholders to a
number which: (1) exceeds by more than two the number of directors last elected
by shareholders where the number was 15 or less; or (2) exceeds by more than
four the number of directors last elected by shareholders where the number was
16 or more, but in no event shall the number of directors exceed 25.

Terms of directors, including directors selected to fill vacancies, shall expire
at the next regular meeting of shareholders at which directors are elected,
unless the directors resign or are removed from office.

Despite the expiration of a director's term, the director shall continue to
serve until his or her successor is elected and qualifies or until there is a
decrease in the number of directors and his or her position is eliminated.


<PAGE>   5


Honorary or advisory members of the Board of Directors, without voting power or
power of final decision in matters concerning the business of the Association,
may be appointed by resolution of a majority of the full Board of Directors, or
by resolution of shareholders at any annual or special meeting. Honorary or
advisory directors shall not be counted to determine the number of directors of
the Association or the presence of a quorum in connection with any board action,
and shall not be required to own qualifying shares.

FOURTH. There shall be an annual meeting of the shareholders to elect directors
and transact whatever other business may be brought before the meeting. It shall
be held at the main office or any other convenient place the Board of Directors
may designate, on the day of each year specified therefor in the Bylaws or, if
that day falls on a legal holiday in the state in which the Association is
located, on the next following banking day. If no election is held on the day
fixed or in the event of a legal holiday on the following banking day, an
election may be held on any subsequent day within 60 days of the day fixed, to
be designated by the Board of Directors or, if the directors fail to fix the
day, by shareholders representing two-thirds of the shares issued and
outstanding. In all cases at least 10 days advance notice of the meeting shall
be given to the shareholders by first class mail.

In all elections of directors, the number of votes each common shareholder may
cast will be determined by multiplying the number of shares such shareholder
owns by the number of directors to be elected. Those votes may be cumulated and
cast for a single candidate or may be distributed among two or more candidates
in the manner selected by the shareholder. On all other questions, each common
shareholder shall be entitled to one vote for each share of stock held by such
shareholder. If the issuance of preferred stock with voting rights has been
authorized by a vote of shareholders owning a majority of the common stock of
the association, preferred shareholders will have cumulative voting rights and
will be included within the same class as common shareholders, for purposes of
elections of directors.

A director may resign at any time by delivering written notice to the Board of
Directors, its chairperson, or to the Association, which resignation shall be
effective when the notice is delivered unless the notice specifies a later
effective date.

A director may be removed by shareholders at a meeting called to remove him or
her, when notice of the meeting stating that the purpose or one of the purposes
is to remove him or her is provided, if there is a failure to fulfill one of the
affirmative requirements for qualification, or for cause, provided, however,
that a director may not be removed if the number of votes sufficient to elect
him or her under cumulative voting is voted against his or her removal.

FIFTH. The authorized amount of capital stock of this Association shall be
eighty thousand shares of common stock of the par value of ten dollars ($10.00)
each; but said capital stock may be increased or decreased from time to time,
according to the provisions of the laws of the United States.

No holder of shares of the capital stock of any class of the Association shall
have any preemptive or preferential right of subscription to any shares of any
class of stock of the Association, whether now or hereafter authorized, or to
any obligations convertible into stock of the Association, issued or sold, nor
any right of subscription to any thereof other than such, if any, as the Board
of Directors, in its discretion, may from time to time


<PAGE>   6


determine and at such price as the Board of Directors may from time to time fix.
Unless otherwise specified in the Articles of Association or required by law,
(1) all matters requiring shareholder action, including amendments to the
Articles of Association, must be approved by shareholders owning a majority
voting interest in the outstanding voting stock, and (2) each shareholder shall
be entitled to one vote per share.

Unless otherwise specified in the Articles of Association or required by law,
all shares of voting stock shall be voted together as a class on any matters
requiring shareholder approval. If a proposed amendment would affect two or more
classes or series in the same or a substantially similar way, all the classes or
series so affected must vote together as a single voting group on the proposed
amendment.

Shares of the same class or series may be issued as a dividend on a pro rata
basis and without consideration. Shares of another class or series may be issued
as share dividends in respect of a class or series of stock if approved by a
majority of the votes entitled to be cast by the class or series to be issued
unless there are no outstanding shares of the class or series to be issued.
Unless otherwise provided by the Board of Directors, the record date for
determining shareholders entitled to a share dividend shall be the date the
Board of Directors authorizes the share dividend.

Unless otherwise provided in the Bylaws, the record date for determining
shareholders entitled to notice of and to vote at any meeting is the close of
business on the day before the first notice is mailed or otherwise sent to the
shareholders, provided that in no event may a record date be more than 70 days
before the meeting.

If a shareholder is entitled to fractional shares pursuant to preemptive rights,
a stock dividend, consolidation or merger, reverse stock split or otherwise, the
Association may: (a) issue fractional shares or; (b) in lieu of the issuance of
fractional shares, issue script or warrants entitling the holder to receive a
full share upon surrendering enough script or warrants to equal a full share;
(c) if there is an established and active market in the Association's stock,
make reasonable arrangements to provide the shareholder with an opportunity to
realize a fair price through sale of the fraction, or purchase of the additional
fraction required for a full share; (d) remit the cash equivalent of the
fraction to the shareholder; or (e) sell full shares representing all the
fractions at public auction or to the highest bidder after having solicited and
received sealed bids from at least three licensed stock brokers, and distribute
the proceeds pro rata to shareholders who otherwise would be entitled to the
fractional shares. The holder of a fractional share is entitled to exercise the
rights for shareholder, including the right to vote, to receive dividends, and
to participate in the assets of the Association upon liquidation, in proportion
to the fractional interest. The holder of script or warrants is not entitled to
any of these rights unless the script or warrants explicitly provide for such
rights. The script or warrants may be subject to such additional conditions as:
(1) that the script or warrants will become void if not exchanged for full
shares before a specified date; and (2) that the shares for which the script or
warrants are exchangeable may be sold at the option of the Association and the
proceeds paid to scriptholders.

The Association, at any time and from time to time, may authorize and issue debt
obligations, whether or not subordinated, without the approval of the
shareholders. Obligations classified as debt, whether or not subordinated, which
may be issued by the Association without the approval of shareholders, do not
carry voting rights on any issue, including an increase or decrease in the
aggregate number of the securities, or the exchange or reclassification of all
or part of securities into securities of another class or series.

SIXTH. The Board of Directors shall appoint one of its members president of this
Association, and one of its members chairperson of the board and shall have the
power to appoint one or more vice presidents, a secretary who shall keep minutes
of the directors' and shareholders' meetings and be responsible for
authenticating the records of the Association, and such other officers and
employees as may be required to transact the business of this Association. A
duly appointed officer may appoint one or more officers or assistant officers if
authorized by the Board of Directors in accordance with the Bylaws. The Board of
Directors shall have the power to:

(1)      Define the duties of the officers, employees, and agents of the
         Association.

(2)      Delegate the performance of its duties, but not the responsibility for
         its duties, to the officers, employees, and agents of the Association.

(3)      Fix the compensation and enter into employment contracts with its
         officers and employees upon reasonable terms and conditions consistent
         with applicable law.

         committees of the board.

(7)      Regulate the manner in which any increase or decrease of the capital of
         the Association shall be made, provided that nothing herein shall
         restrict the power of shareholders to increase or decrease the capital
         of the association in accordance with law, and nothing shall raise or
         lower from two-thirds the percentage for shareholder approval to
         increase or reduce the capital.

(8)      Manage and administer the business and affairs of the Association.

(9)      Adopt initial Bylaws, not inconsistent with law or the Articles of
         Association, for managing the business and regulating the affairs of

         Association reserve this power in whole or in part to shareholders.

(11)     Make contracts.

         perform.

the main office of this Association to any other place within the limits of the
City of Columbus, State of Ohio, without the approval of the shareholders; and
shall have the power to change the location of the main office of this
Association to any other place outside the limits of the City of Columbus, State
of Ohio, but not more than thirty miles beyond such limits, with the affirmative
vote of shareholders owning two-thirds of the stock of the Association, subject
to receipt of a certificate of approval from the Comptroller of the Currency.
The Board of Directors shall have the power to establish or change the location
of any branch or branches of the Association to any other location permitted
under applicable law without the approval of the shareholders, subject to
approval by the Office of the Comptroller of the Currency. The Board of
Directors shall have the power to establish or change the location of any
nonbranch office or facility of the Association without the approval of the
shareholders.

EIGHTH. The corporate existence of this Association shall continue until
termination according to the laws of the United States.

NINTH. The Board of Directors of this Association, or any shareholders owning,
in the aggregate, not less than 20 percent of the stock of this Association, may
call a special meeting of shareholders at any time. Unless otherwise provided by
the Bylaws or the laws of the United States, or waived by shareholders, a notice
of the time, place, and purpose of every annual and special meeting of the
shareholders shall be given by first-class mail, postage prepaid, mailed at
least 10, and no more than 60, days prior to the date of the meeting to each
shareholder of record at his/her address as shown upon the books of this
Association. Unless otherwise provided by the Bylaws, any action requiring
approval of shareholders must be effected at a duly called annual or special
meeting.

TENTH.  The Association shall provide indemnification as set forth below:

Every person who is or was a Director, officer or employee of the Association or
of any other corporation which he served as a Director, officer or employee at
the request of the Association as part of his regularly assigned duties may be
indemnified by the Association in accordance with the provisions of this Article
against all liability (including, without limitation, judgments, fines,
penalties, and settlements) and all reasonable expenses (including, without
limitation, attorneys' fees and investigative expenses) that may be incurred or
paid by him in connection with any claim, action, suit or proceeding, whether
civil, criminal or administrative (all referred to hereafter in this Article as
"Claims") or in connection with any appeal relating thereto in which he may
become involved as a party or otherwise or with which he may be threatened by
reason of his being or having been a Director, officer or employee of the
Association or such other corporation, or by reason of any action taken or
omitted by him in his capacity as such Director, officer or employee, whether or
not he continues to be such at the time such liability or expenses are incurred;
provided that nothing contained in this Article shall be construed to permit
indemnification of any such person who is adjudged guilty of, or liable for,
willful misconduct, gross neglect of duty or criminal acts, unless, at the time
such indemnification is sought, such indemnification in such instance is
permissible under applicable law and regulations, including published rulings of
the Comptroller of the Currency or other appropriate

<PAGE>   9


supervisory or regulatory authority; and provided further that there shall be no
indemnification of Directors, officers, or employees against expenses,
penalties, or other payments incurred in an administrative proceeding or action
instituted by an appropriate regulatory agency which proceeding or action
results in a final order assessing civil money penalties or requiring
affirmative action by an individual or individuals in the form of payments to
the Association.

Every person who may be indemnified under the provisions of this Article and who
has been wholly successful on the merits with respect to any Claim shall be
entitled to indemnification as of right. Except as provided in the preceding
sentence, any indemnification under this Article shall be at the sole discretion
of the Board of Directors and shall be made only if the Board of Directors or
the Executive Committee acting by a quorum consisting of Directors who are not
parties to such Claim shall find or if independent legal counsel (who may be the
regular counsel of the Association) selected by the Board of Directors or
Executive Committee whether or not a disinterested quorum exists shall render
their opinion that in view of all of the circumstances then surrounding the
Claim, such indemnification is equitable and in the best interests of the
Association. Among the circumstances to be taken into consideration in arriving
at such a finding or opinion is the existence or non-existence of a contract of
insurance or indemnity under which the Association would be wholly or partially
reimbursed for such indemnification, but the existence or non-existence of such
insurance is not the sole circumstance to be considered nor shall it be wholly
determinative of whether such indemnification shall be made. In addition to such
finding or opinion, no indemnification under this Article shall be made unless
the Board of Directors or the Executive Committee acting by a quorum consisting
of Directors who are not parties to such Claim shall find or if independent
legal counsel (who may be the regular counsel of the Association) selected by
the Board of Directors or Executive Committee whether or not a disinterested
quorum exists shall render their opinion that the Directors, officer or employee
acted in good faith in what he reasonably believed to be the best interests of
the Association or such other corporation and further in the case of any
criminal action or proceeding, that the Director, officer or employee reasonably
believed his conduct to be lawful. Determination of any Claim by judgment
adverse to a Director, officer or employee by settlement with or without Court
approval or conviction upon a plea of guilty or of NOLO CONTENDERE or its
equivalent shall not create a presumption that a Director, officer or employee
failed to meet the standards of conduct set forth in this Article. Expenses
incurred with respect to any Claim may be advanced by the Association prior to
the final disposition thereof upon receipt of an undertaking satisfactory to the
Association by or on behalf of the recipient to repay such amount unless it is
ultimately determined that he is entitled to indemnification under this Article.

The rights of indemnification provided in this Article shall be in addition to
any rights to which any Director, officer or employee may otherwise be entitled
by contract or as a matter of law. Every person who shall act as a Director,
officer or employee of this Association shall be conclusively presumed to be
doing so in reliance upon the right of indemnification provided for in this
Article.

meeting of the shareholders by the affirmative vote of the holders of a majority

amount of stock is required by law, and in that case by the vote of the holders
of such greater amount. The Association's Board of Directors may propose one or
more amendments to the Articles of Association for submission to the

                            MEETINGS OF SHAREHOLDERS


SECTION 1.01. ANNUAL MEETING. The regular annual meeting of the shareholders of
the Bank for the election of Directors and for the transaction of such business
as may properly come before the meeting shall be held at its main office, or
other convenient place duly authorized by the Board of Directors, on the same
day upon which any regular or special Board meeting is held from and including
the first Monday of January to, and including, the fourth Monday of February of
each year, or on the next succeeding banking day, if the day fixed falls on a
legal holiday. If from any cause, an election of Directors is not made on the
day fixed for the regular meeting of the shareholders or, in the event of a
legal holiday, on the next succeeding banking day, the Board of Directors shall
order the election to be held on some subsequent day, as soon thereafter as
practicable, according to the provisions of law; and notice thereof shall be

SECTION 1.03. SECRETARY OF MEETING OF SHAREHOLDERS. The Board of Directors may
designate a person to be the secretary of the meeting of shareholders. In the
absence of a presiding officer, as designated by these By-Laws, the Board of
Directors may designate a person to act as the presiding officer. In the event
the Board of Directors fails to designate a person to preside at a meeting of
shareholders and a secretary of such meeting, the shareholders present or
represented shall elect a person to preside and a person to serve as secretary
of the meeting. The secretary of the meeting of shareholders shall cause the
returns made by the judges of election and other proceedings to be recorded in
the minute books of the Bank. The presiding officer shall notify the

their signatures, the secretary of the meeting of shareholders of the result
thereof and the names of the Directors elected; provided, however, that upon
failure for any reason of any judge or judges of election, so appointed by the
Directors, to serve, the presiding officer of the meeting shall appoint other
shareholders or their proxies to fill the vacancies. The judges of election, at
the request of the chairman of the meeting, shall act as tellers of any other
vote by ballot taken at such meeting, and shall notify, in writing over their
signature, the secretary of the Board of Directors of the result thereof.

SECTION 1.05. PROXIES. In all elections of Directors, each shareholder of
record, who is qualified to vote under the provisions of Federal Law, shall have
the right to vote the number of shares of record in such shareholder's name for
as many persons as there are Directors to be elected, or to cumulate such shares
as provided by Federal Law. In deciding all other questions at meetings of
shareholders, each shareholder shall be entitled to one vote on each share of
stock of record in such shareholder's name. Shareholders may vote by proxy duly
authorized in writing. All proxies used at the annual meeting shall be secured
for that meeting only, or any adjournment thereof, and shall be dated, if not
dated by the shareholder, as of the date of the receipt thereof. No officer or
employee of this Bank may act as proxy.

SECTION 1.06. QUORUM. Holders of record of a majority of the shares of the
capital stock of the Bank, eligible to be voted, present either in person or by
proxy, shall constitute a quorum for the transaction of business at any meeting

than a quorum may, without further notice, adjourn the meeting from time to time
until a quorum is obtained. A majority of the votes cast shall decide every
question or matter submitted to the shareholders at any meeting, unless
otherwise provided by law or by the Articles of Association.

powers of office until such Director has taken the oath of such office.

SECTION 2.02. VACANCIES. Directors of the Bank shall hold office for one year or
until their successors are elected and qualified. Any vacancy in the Board shall
be filled by


<PAGE>   15


appointment of the remaining Directors, and any Director so appointed shall hold
office until the next election.

SECTION 2.03. ORGANIZATION MEETING. The Directors elected by the shareholders
shall meet for organization of the new Board of Directors at the time and place
fixed by the presiding officer of the annual meeting. If at the time fixed for
such meeting there is no quorum present, the Directors in attendance may adjourn
from time to time until a quorum is obtained. A majority of the number of
Directors elected by the shareholders shall constitute a quorum for the
transaction of business.

SECTION 2.04. REGULAR MEETINGS. The regular meetings of the Board of Directors
shall be held at such date, time and place as the Board may previously
designate, or should the Board fail to so designate, at such date, time and
place as the Chairman of the Board, Chief Executive Officer, or President may
fix. Whenever a quorum is not present, the Directors in attendance shall adjourn
the meeting to a time not later than the date fixed by the By-Laws for the next
succeeding regular meeting of the Board. Members of the Board of Directors may
participate in such meetings through use of conference telephone or similar
communications equipment, so long as all members participating in such meetings
can hear one another.

SECTION 2.05. SPECIAL MEETINGS. Special meetings of the Board of Directors shall
be held at the call of the Chairman of the Board, Chief Executive Officer, or
President, or at the request of two or more Directors. Any special meeting may
be held at such place and at such time as may be fixed in the call. Written or
oral notice shall be given to each Director not later than the day next
preceding the day on which the special meeting is to be held, which notice may
be waived in writing. The presence of a Director at any meeting of the Board of
Directors shall be deemed a waiver of notice thereof by such Director. Whenever
a quorum is not present, the Directors in attendance shall adjourn the special
meeting from day to day until a quorum is obtained. Members of the Board of
Directors may participate in such meetings through use of conference telephone
or similar communications equipment, so long as all members participating in
such meetings can hear one another.

SECTION 2.06. QUORUM. A majority of the Directors shall constitute a quorum at
any meeting, except when otherwise provided by law; but a lesser number may
adjourn any meeting, from time-to-time, and the meeting may be held, as
adjourned, without further notice. When, however, less than a quorum as herein
defined, but at least one-third and not less than two of the authorized number
of Directors are present at a meeting of the Directors, business of the Bank may
be transacted and matters before the Board approved or disapproved by the
unanimous vote of the Directors present.

SECTION 2.07. COMPENSATION. Each member of the Board of Directors shall receive
such fees for attendance at Board and Board committee meetings and such fees for
service as a Director, irrespective of meeting attendance, as from time to time
are fixed by resolution of the Board; provided, however, that payment hereunder
shall not be made to a Director for meetings attended and/or Board service which
are not for the Bank's sole


<PAGE>   16


benefit and which are concurrent and duplicative with meetings attended or Board
service for an affiliate of the Bank for which the Director receives payment;
and provided further that fees hereunder shall not be paid in the case of any
Director in the regular employment of the Bank or of one of its affiliates. Each
member of the Board of Directors, whether or not such Director is in the regular
employment of the Bank or of one of its affiliates, shall be reimbursed for
travel expenses incident to attendance at Board and Board committee meetings.

SECTION 2.08. EXECUTIVE COMMITTEE. There may be a standing committee of the
Board of Directors known as the Executive Committee which shall possess and
exercise, when the Board is not in session, all the powers of the Board that may
lawfully be delegated. The Executive Committee shall consist of at least three
Board members, one of whom shall be the Chairman of the Board, Chief Executive
Officer or the President. The other members of the Executive Committee shall be
appointed by the Chairman of the Board, the Chief Executive Officer, or the
President, with the approval of the Board, and who shall continue as members of
the Executive Committee until their successors are appointed, provided, however,
that any member of the Executive Committee may be removed by the Board upon a
majority vote thereof at any regular or special meeting of the Board. The
Chairman, Chief Executive Officer, or President shall fill any vacancy in the
Executive Committee by the appointment of another Director, subject to the
approval of the Board of Directors. The Executive Committee shall meet at the
call of the Chairman, Chief Executive Officer, or President or any two members
thereof at such time or times and place as may be designated. In the event of
the absence of any member or members of the Executive Committee, the presiding
member may appoint a member or members of the Board to fill the place or places
of such absent member or members to serve during such absence. Two members of
the Executive Committee shall constitute a quorum. When neither the Chairman of
the Board, the Chief Executive Officer, nor President are present, the Executive
Committee shall appoint a presiding officer. The Executive Committee shall
report its proceedings and the action taken by it to the Board of Directors.

SECTION 2.09. OTHER COMMITTEES. The Board of Directors may appoint such special
committees from time to time as are in its judgment necessary in the interest of
the Bank.

offices may be held by the same person except that no person shall hold the
office of Chairman of the Board, Chief Executive Officer and/or President and at
the same time also hold the office of Secretary.

(c) Except as provided in the case of the elected officers who are members of
the Board, all officers and employees, whether elected or appointed, shall hold

By-Laws, the Board assigns to the Chairman of the Board, the Chief Executive
Officer, the President, any Senior Managing Director, any Managing Director, the
Chief Financial Officer, and/or each of their respective designees the authority
to control all personnel, including elected and appointed officers and employees
of the Bank, to employ or direct the employment of such officers and employees
as he or she may deem necessary, including the fixing of salaries and the
dismissal of such officers and employees at pleasure, and to define and
prescribe the duties and responsibilities of all officers and employees of the
Bank, subject to such further limitations and directions as he or she may from
time to time deem appropriate.

(d) The Chairman of the Board, the Chief Executive Officer, the President, any
Senior Managing Director, any Managing Director, the Chief Financial Officer,

Financial Officer may appoint persons other than officers who are in employment
of the Bank to serve in management positions and in connection therewith, the
appointing officer may assign such title, salary, responsibilities and functions
as are deemed appropriate, provided, however, that nothing contained herein
shall be construed as placing any limitation on the authority of the Chairman of
the Board, the Chief Executive Officer, the President, any Senior Managing
Director, any Managing Director, or the Chief Financial Officer as provided in
this and other sections of these By-Laws.

(e) The Senior Managing Directors and the Managing Directors of the Bank shall

applicable law and regulations. Each Senior Managing Director and Managing
Director shall perform all duties incident to his or her office and such other
and further duties, as may from time to time be required by the Chief Executive
Officer, the President, the Board of Directors, or the shareholders. The
specification of authority in these By-Laws wherever and to whomever granted
shall not be construed to limit in any manner the general powers of delegation
granted to a Senior Managing Director or a Managing Director in conducting the
business of the Bank. In the absence of a Senior Managing Director or a Managing
Director, such officer as is designated by the Senior Managing Director or the
Managing Director shall be vested with all the powers and perform all the duties

The Managing Director shall fill any vacancy in the Investment Management and
Trust Committee by the appointment of another capable and experienced officer of
the Bank. Each Investment Management and Trust Committee shall meet at such

absence of any member or members of the Investment Management and Trust
Committee, the Managing Director may, in his or her discretion, appoint another
officer of the Bank to fill the place or places of such absent member or members
to serve during such absence. A majority of each Investment Management and Trust
Committee shall constitute a quorum. Each Investment Management and Trust
Committee shall carry out the policies of the Bank, as adopted by the Board of
Directors, which shall be formulated and executed in accordance with State and
Federal Law, Regulations of the Comptroller of the Currency, and sound fiduciary
principles. In carrying out the policies of the Bank, each Investment Management
and Trust Committee is hereby authorized to establish management teams whose
duties and responsibilities shall be specifically set forth in the policies of
the Bank. Each such management team shall report such proceedings and the
actions taken thereby to the Investment Management and Trust Committee. Each

thereby to the Board of Directors.

                          STOCKS AND STOCK CERTIFICATES


SECTION 4.01. STOCK CERTIFICATES. The shares of stock of the Bank shall be
evidenced by certificates which shall bear the signature of the Chairman of the
Board, the Chief Executive Officer, or the President (which signature may be
engraved, printed or impressed), and shall be signed manually by the Secretary,
or any other officer appointed by the Chief Executive Officer for that purpose.
In case any such officer who has signed or whose facsimile signature has been
placed upon such certificate shall have ceased to be such officer before such
certificate is issued, it may be issued by the Bank with the same effect as if
such officer had not ceased to be such at the time of its issue. Each such
certificate shall bear the corporate seal of the Bank, shall recite on its face
that stock represented thereby is transferable only upon the books of the Bank
when properly endorsed and shall recite such other information as is required by
law and deemed appropriate by the Board. The corporate seal may be facsimile
engraved or printed.

SECTION 4.02. STOCK ISSUE AND TRANSFER. The shares of stock of the Bank shall be
transferable only upon the stock transfer books of the Bank and, except as
hereinafter provided, no transfer shall be made or new certificates issued
except upon the surrender for cancellation of the certificate or certificates
previously issued therefor. In the case of the loss, theft, or destruction of
any certificate, a new certificate may be issued in place of such certificate
upon the furnishing of an affidavit setting forth the circumstances of such
loss, theft, or destruction and indemnity satisfactory to the Chairman of the
Board, the Chief Executive Officer, or the President. The Board of Directors or
the Chairman of the Board, Chief Executive Officer, or the President may
authorize the issuance of a new certificate therefor without the furnishing of
indemnity. Stock transfer books, in which all transfers of stock shall be
recorded, shall be provided. The stock transfer books may be closed for a
reasonable period and under such conditions as the Board of Directors may at any
time determine, for any meeting of shareholders, the payment of dividends or any
other lawful purpose. In lieu of closing the transfer books, the Board of
Directors may, in its discretion, fix a record date and hour constituting a
reasonable period prior to the day designated for the holding of any meeting of
the shareholders or the day appointed for the payment of any dividend, or for
any other purpose at the time as of which shareholders entitled to notice of and
to vote at any such meeting or to receive such dividend or to be treated as
shareholders for such other purpose shall be determined, and only shareholders
of record at such time shall be entitled to notice of or to vote at such meeting
or to receive such dividends or to be treated as shareholders for such other
purpose.
