                           INCORPORATION BY REFERENCE

reference the documents listed below and any future filings Minnesota Power
makes with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities
Exchange Act of 1934, until Minnesota Power sells all of the Securities
described in this prospectus. Information that Minnesota Power files in the

                           SAFE HARBOR STATEMENT UNDER
              THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

     In connection with the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995, Minnesota Power is hereby filing cautionary
statements identifying important factors that could cause Minnesota Power's
actual results to differ materially from those projected in forward-looking
statements (as that term is defined in the Private Securities Litigation Reform
Act of 1995) made by or on behalf of Minnesota Power which are made in this
prospectus or any supplement to this prospectus, in presentations, in response
to questions or otherwise. Any statements that express, or involve discussions


<PAGE>


as to, expectations, beliefs, plans, objectives, assumptions or future events or
performance (often, but not always, through the use of words or phrases such as
"anticipates," "believes," "estimates," "expects," "intends," "plans,"
"projects," "will likely," "result," "will continue" or similar expressions) are
not statements of historical facts and may be forward-looking.

     Forward-looking statements involve estimates, assumptions and uncertainties
and are qualified in their entirety by reference to, and are accompanied by, the
following important factors, which are difficult to predict, contain
uncertainties, are beyond the control of Minnesota Power and may cause actual
results to differ materially from those contained in those forward-looking
statements:

     o    prevailing governmental policies and regulatory actions, including
          those of Congress, state legislatures, the Federal Energy Regulatory
          Commission, the Minnesota Public Utilities Commission, the Florida
          Public Service Commission, the North Carolina Utilities Commission and
          the Public Service Commission of Wisconsin, with respect to allowed
          rates of return, industry and rate structure, acquisition and disposal
          of assets and facilities, operation and construction of plant
          facilities, recovery of purchased power, and present or prospective
          wholesale and retail competition (including but not limited to retail
          wheeling and transmission costs);

     o    economic and geographic factors including political and economic
          risks;

     o    changes in and compliance with environmental and safety laws and
          policies;

     o    weather conditions;

     o    population growth rates and demographic patterns;

     o    competition for retail and wholesale customers;

     o    pricing and transportation of commodities;

     o    market demand, including structural market changes;

     o    changes in tax rates or policies or in rates of inflation;

     o    changes in project costs;

     o    unanticipated changes in operating expenses and capital expenditures;

     o    capital market conditions;

     o    competition for new energy development opportunities; and

     o    legal and administrative proceedings (whether civil or criminal) and
          settlements that influence the business and profitability of Minnesota
          Power.

     Any forward-looking statement speaks only as of the date on which that
statement is made, and Minnesota Power undertakes no obligation to update any
forward-looking statement to reflect events or circumstances after the date on
which that statement is made or to reflect the occurrence of unanticipated
events. New factors emerge from time to time and it is not possible for
management to predict all of those factors, nor can it assess the impact of each
of those factors on the business or the extent to which any factor, or
combination of factors, may cause actual results to differ materially from those
contained in any forward-looking statement.

     exchange of its investment in Capital Re stock for the ACE shares,
     including a $24.1 million, or $0.35 per share charge in the second quarter.

ELECTRIC SERVICES

     Electric Services generate, transmit, distribute and market electricity. In
addition, Electric Services include coal mining, telecommunications,
engineering, operating and maintenance services, and economic development
projects in and near Minnesota Power's service area. As of June 30, 2000,
Minnesota Power was supplying retail electric service to 130,000 customers in
153 cities, towns and communities, and outlying rural areas of northeastern
Minnesota. Minnesota Power's wholly owned subsidiary, Superior Water, Light and
Power Company, was providing electric, natural gas, and water services to 14,000
electric customers, 11,000 natural gas customers and 10,000 water customers in
northwestern Wisconsin as of June 30, 2000.

     BNI Coal, Ltd., another wholly owned subsidiary of Minnesota Power, owns
and operates a lignite mine in North Dakota. Two electric generating
cooperatives, Minnkota Power Cooperative, Inc. and Square Butte Electric
Cooperative, presently consume virtually all of BNI Coal's production of lignite
coal under cost-plus coal supply agreements extending to 2027. Under an
agreement with Square Butte, Minnesota Power purchases approximately 71 percent


                                       3
<PAGE>


of the output from the Square Butte unit which is capable of generating up to
455 MW. Minnkota Power has an option to extend its coal supply agreement to
2042.

     Other wholly owned subsidiaries of Minnesota Power within the Electric
Services business segment include:

     o    Electric Outlet, Inc., doing business as Electric Odyssey, which is a

          housing projects located in Minnesota Power's service territory.

     Minnesota Power has large power contracts to sell power to eleven
industrial customers (five taconite producers, four paper and pulp mills, and
two pipeline companies) each requiring 10 megawatts or more of generating
capacity. These contracts require the payment of minimum monthly demand charges
that cover the fixed costs associated with having capacity available to serve
each of these customers, including a return on common equity. Each contract
continues past the contract termination date unless the required four-year
advance notice of cancellation has been given.

AUTOMOTIVE SERVICES

     Automotive Services includes several subsidiaries which are integral parts
of the vehicle redistribution business. ADESA Corporation, a wholly owned
subsidiary of Minnesota Power, is the second largest vehicle auction network in
North America. Headquartered in Indianapolis, Indiana, ADESA owns, or leases,
and operates 45 vehicle auction facilities in the United States and Canada
through which used cars and other vehicles are sold to franchised automobile
dealers and licensed used car dealers. Sellers at ADESA's auctions include
domestic and foreign auto manufacturers, car dealers, automobile fleet/lease
companies, banks and finance companies.

          fleet operations; and

     o    AutoVIN, Inc., 90 percent owned, which provides professional field
          information service to the automotive industry, including vehicle
          condition reporting, inventory verification auditing, program
          compliance auditing and facility inspection.

WATER SERVICES

     Water Services include Florida Water Services Corporation, Heater
Utilities, Inc., Instrumentation Services, Inc., Vibration Correction Services,
Inc., and Americas' Water Service Corporation, each a wholly owned subsidiary of
Minnesota Power. Florida Water, the largest investor owned water supplier in
Florida, owns and operates water and wastewater treatment facilities within that
state. As of June 30, 2000, Florida Water served 148,000 water customers and


                                       4

INVESTMENTS

     Investments consist of an actively traded securities portfolio,
intermediate-term investments and real estate operations. As of June 30, 2000,
Minnesota Power had approximately $113.7 million invested in a trading and
available-for-sale securities portfolio. Since 1985 Minnesota Power has invested
$27.9 million in venture capital funds that seek long-term capital appreciation
by making investments in companies developing advanced technologies to be used
by the electric utility industry. In addition, through subsidiaries, Minnesota
Power owns Cape Coral Holdings, Inc. and 80 percent of Lehigh Acquisition
Corporation, real estate companies that own various real estate properties and
operations in Florida.

                                 USE OF PROCEEDS

     Unless otherwise stated in the prospectus supplement, Minnesota Power will
add the net proceeds from sales of the Securities to its general funds.
Minnesota Power uses its general funds for general corporate purposes,
including, without limitation, acquisitions made by or on behalf of Minnesota
Power or its subsidiaries, to repay short-term borrowings and to redeem or
repurchase outstanding long-term debt obligations. Minnesota Power will
temporarily invest any proceeds that it does not need to use immediately in
short-term instruments.

                 CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES

     Minnesota Power has calculated ratios of earnings to fixed charges as
follows:

                         YEAR ENDED DECEMBER 31,
               ------------------------------------------
                                                             SIX MONTHS ENDED
                                                             ----------------

     Minnesota Power has calculated supplemental ratios of earnings to fixed
charges as follows:

                         YEAR ENDED DECEMBER 31,
               ------------------------------------------
                                                             SIX MONTHS ENDED

     The supplemental ratio of earnings to fixed charges includes Minnesota
Power's obligation under a contract with Square Butte which extends through
2027, pursuant to which Minnesota Power is entitled to approximately 71 percent
of the output of a 455-megawatt coal-fired generating unit. Minnesota Power is
obligated to pay its pro rata share of Square Butte's costs based on output
entitlement from the unit. Minnesota Power's payment obligation is suspended if
Square Butte fails to deliver any power, whether produced or purchased, for a
period of one year. Square Butte's fixed costs consist primarily of debt


                                       5

service. Variable operating costs include the price of coal purchased from BNI
Coal under a long-term contract.

                       DESCRIPTION OF FIRST MORTGAGE BONDS

     General. The first mortgage bonds are to be issued under Minnesota Power's
Mortgage and Deed of Trust, dated as of September 1, 1945, with Irving Trust
Company (now The Bank of New York) and Richard H. West (Douglas J. MacInnes,
successor), as mortgage trustees ("Mortgage Trustee" or "Mortgage Trustees"), as
supplemented by twenty supplemental indentures (herein collectively referred to
as the "Mortgage"), all of which are exhibits to the registration statement. The
statements herein with respect to the first mortgage bonds offered by this
prospectus and the Mortgage are merely an outline and do not purport to be
complete. They make use of terms defined in the Mortgage and are qualified in
their entirety by express reference to the cited articles and sections of the
Mortgage. All first mortgage bonds issued or to be issued under the Mortgage,
including the first mortgage bonds offered by this prospectus, are referred to
herein as "First Mortgage Bonds."

     Reference is made to a prospectus supplement relating to each series of
First Mortgage Bonds offered by this prospectus for the following specific terms
of that series, among others:

     o    the designation of the series of First Mortgage Bonds and aggregate
          principal amount of the First Mortgage Bonds;

     o    the percentage or percentages of their principal amount at which the
          series will be issued;

     o    the date or dates on which the series will mature;

     o    the rate or rates at which the series will bear interest;

     o    the times at which such interest will be payable; and

     o    redemption terms or other specific terms.

     Form and Exchanges. The First Mortgage Bonds offered by this prospectus
will be issued in definitive fully registered form without coupons in
denominations of $1,000 and multiples thereof and will be transferable and
exchangeable without charge (except for stamp taxes, if any, or other
governmental charges) at The Bank of New York, in The City of New York.

     Interest, Maturity and Payment. Reference is made to the prospectus
supplement for the interest rate or rates of the First Mortgage Bonds offered by
this prospectus and the dates on which such interest is payable. Principal and
interest are payable at The Bank of New York, in The City of New York.

     Redemption and Purchase of First Mortgage Bonds. The First Mortgage Bonds
may be redeemable mandatorily or at the option of Minnesota Power upon 30 days
notice at predetermined prices. If the First Mortgage Bonds are redeemable,
Minnesota Power may use certain deposited cash and/or proceeds of released
property to effect the redemption. Reference is made to the prospectus
supplement for the redemption terms of the First Mortgage Bonds offered by this
prospectus.

     If at the time notice of redemption is given the redemption moneys are not
on deposit with The Bank of New York, as Mortgage Trustee, the redemption may be
made subject to their receipt before the date fixed for redemption.

     Cash deposited under any provisions of the Mortgage (with certain
exceptions) may generally be applied to the purchase of First Mortgage Bonds of
any series. (See Mortgage, Article X.)


                                       6
<PAGE>


     Sinking or Improvement Fund. Reference is made to the prospectus supplement
concerning whether or not the First Mortgage Bonds offered by this prospectus
are entitled to the benefit of a sinking or improvement fund or other provision
for amortization prior to maturity. None of the currently outstanding First
Mortgage Bonds has sinking fund or improvement fund provisions.

     Replacement Fund. The First Mortgage Bonds offered by this prospectus are
not entitled to the benefit of any replacement fund.

     Special Provisions for Retirement of First Mortgage Bonds. If, during any
12 month period, mortgaged property is disposed of by order of or to any
governmental authority resulting in the receipt of $5 million or more as
proceeds, Minnesota Power (subject to certain conditions) must apply such
proceeds, less certain deductions, to the retirement of First Mortgage Bonds.
(See Mortgage, Section 64.) Reference is made to the prospectus supplement for
information concerning whether the First Mortgage Bonds offered by this
prospectus are redeemable for this purpose and, if so, at what redemption
prices.

     Security. The First Mortgage Bonds offered by this prospectus and any other
First Mortgage Bonds now or hereafter issued under the Mortgage will be secured
by the Mortgage, which constitutes, in the opinion of General Counsel for
Minnesota Power, a first lien on all of the electric generating plants and other
materially important physical properties of Minnesota Power and substantially
all other properties described in the Mortgage as owned by Minnesota Power,
subject to

     o    leases of minor portions of Minnesota Power's property to others for
          uses which, in the opinion of such counsel, do not interfere with
          Minnesota Power's business,

     o    leases of certain property of Minnesota Power not used in its electric
          utility business, and

     o    excepted encumbrances, minor defects and irregularities,

but such counsel has not examined title to or passed upon title to reservoir
lands, easements or rights of way, any property not costing in excess of
$25,000, or lands or rights held for flowage, flooding or seepage purposes, or
riparian rights. There are excepted from the lien:

     o    cash and securities;

     o    merchandise, equipment, materials or supplies held for sale or other
          disposition;

     o    aircraft, automobiles and other vehicles, and materials and supplies
          for repairing and replacing the same;

     o    timber, minerals, mineral rights and royalties; and

     o    receivables, contracts, leases and operating agreements.

     The Mortgage contains provisions that impose the lien of the Mortgage on
property acquired by Minnesota Power after the date of the Mortgage, other than
the excepted property, subject to pre-existing liens. However, if Minnesota
Power consolidates or merges with or conveys or transfers all or substantially
all of the mortgaged property to another corporation, the lien created by the
Mortgage will generally not cover the property of the successor company, other
than the property it acquires from Minnesota Power and improvements,
replacements and additions to that property. (See Mortgage, Section 87.)

     The Mortgage provides that the Mortgage Trustees shall have a lien upon the
mortgaged property, prior to the First Mortgage Bonds, for the payment of their
reasonable compensation, expenses and disbursements and for indemnity against
certain liabilities. (See Mortgage, Section 96.)


                                       7
<PAGE>


     No stocks or properties of subsidiaries are subject to the Mortgage.

     Issuance of Additional First Mortgage Bonds. The maximum principal amount
of First Mortgage Bonds which may be issued under the Mortgage is not limited.
First Mortgage Bonds of any series may be issued from time to time on the basis
of:

     (1)  60 percent of property additions after adjustments to offset
          retirements;

     (2)  retirement of First Mortgage Bonds or qualified lien bonds; and

     (3)  deposit of cash.

     With certain exceptions in the case of (2) above, the issuance of First
Mortgage Bonds requires adjusted net earnings before income taxes for 12 out of
the preceding 15 months of at least twice the annual interest requirements on
all First Mortgage Bonds at the time outstanding, including the additional
issue, and on all indebtedness of prior rank. Such adjusted net earnings are
computed after provision for retirement and depreciation of property equal to
$750,000 plus, for each of the 12 calendar months selected for the net earnings
test, 1/12th of 2 percent of the net additions to depreciable mortgaged property
made after June 30, 1945 and prior to the beginning of the calendar year within
which that calendar month is included. It is expected that the First Mortgage
Bonds offered by this prospectus will be issued upon the basis of the retirement
of First Mortgage Bonds or property additions.

     Property additions generally include electric, gas, steam or hot water
property acquired after June 30, 1945, but may not include securities, aircraft,
automobiles or other vehicles, or property used principally for the production
or gathering of natural gas. There was available, as of June 30, 2000, unfunded
net property additions of approximately $77 million.

     Minnesota Power has the right to amend the Mortgage without any consent or
other action by holders of any series of First Mortgage Bonds, including the
holders of First Mortgage Bonds offered by this prospectus, so as to include
nuclear fuel as well as similar or analogous devices or substances as property
additions.

     The Mortgage contains certain restrictions upon the issuance of First
Mortgage Bonds against property subject to liens and upon the increase of the
amount of such liens. (See Mortgage, Sections 4-8, 20-30, and 46; Fifth
Supplemental, Section 2.)

     Release and Substitution of Property. Property may be released upon the
basis of:

     (1)  deposit of cash or, to a limited extent, purchase money mortgages;

     (2)  property additions, after adjustments in certain cases to offset
          retirement and after making adjustments for qualified lien bonds
          outstanding against property additions; and/or

     (3)  waiver of the right to issue First Mortgage Bonds without applying any
          earnings test.

     Cash may be withdrawn upon the bases stated in (2) and (3) above.

     When property released is not funded property, property additions used to
effect the release may again, in certain cases, become available as credits
under the Mortgage, and the waiver of the right to issue First Mortgage Bonds to
effect the release may, in certain cases, cease to be effective as such a
waiver. Similar provisions are in effect as to cash proceeds of such property.
The Mortgage contains special provisions with respect to qualified lien bonds
pledged, and disposition of moneys received on pledged prior lien bonds. (See
Mortgage, Sections 5, 31, 32, 37, 46-50, 59-63, 100 and 118.)

     Dividend Covenant. Minnesota Power covenants that it will not declare or
pay dividends, other than dividends payable in common stock, on or make any
other distributions on or acquire, unless without cost to it, any of its common
stock unless


                                       8
<PAGE>


     o    the provisions for depreciation and retirement of property during the
          period beginning September 1, 1945 to the date of the proposed
          payment, distribution or acquisition, plus

     o    earned surplus of Minnesota Power, including current net income
          available to be transferred to earned surplus, remaining:

          (1)  after such payment, distribution or acquisition; and

          (2)  after deducting any remainder of the amount of earned surplus of
               Minnesota Power as of August 31, 1945, after deducting from such
               amount the charges to earned surplus subsequent to August 31,
               1945, other than charges occasioned by dividends (other than
               dividends payable in common stock) on its common stock or
               occasioned by other distributions on or acquisitions of its
               common stock and other than charges to earned surplus with
               corresponding credits to reserve for depreciation and retirement
               of property;

shall be at least equal to

     o    $1,000,000 plus, for each calendar year 1947 through 1996, $750,000
          plus 2 percent of net additions to depreciable mortgaged property made
          after June 30, 1945 through that calendar year. (See Mortgage, Section
          39.) None of Minnesota Power's retained earnings as of June 30, 2000
          were restricted as a result of such provisions.

     Modification of the Mortgage. The rights of bondholders may be modified
with the consent of the holders of 70 percent of the First Mortgage Bonds and,
if less than all series of First Mortgage Bonds are affected, the consent also
of the holders of 70 percent of the First Mortgage Bonds of each series
affected. Minnesota Power has reserved the right without any consent or other
action by the holders of any series of First Mortgage Bonds, including the
holders of First Mortgage Bonds offered by this prospectus, to amend the
Mortgage so as to substitute 66-2/3 percent for 70 percent in the foregoing
provisions. In general, no modification of the terms of payment of principal and
interest, no modification of the obligations of Minnesota Power under Section 64
and no modification affecting the lien or reducing the percentage required for
modification, is effective against any bondholder without his consent. (See
Mortgage, Article XIX; Fifth Supplemental, Section 3.)

     Defaults and Notice Thereof. Defaults are defined as being:

     o    default in payment of principal;

     o    default for 60 days in payment of interest or of installments of funds
          for retirement of First Mortgage Bonds;

     o    certain defaults with respect to qualified lien bonds and certain
          events in bankruptcy, insolvency or reorganization; and

     o    default of 90 days after notice in other covenants. (See Mortgage,
          Section 65.)

     The Mortgage Trustees may withhold notice of default, except in payment of
principal, interest or funds for retirement of First Mortgage Bonds, if they
think it is in the interest of the bondholders. (See Mortgage, Section 66.)
Under the Trust Indenture Act of 1939, Minnesota Power is required to provide to
the Mortgage Trustees an annual statement by an appropriate officer as to
Minnesota Power's compliance with all conditions and covenants under the
Mortgage.

     The Bank of New York, as Mortgage Trustee, or the holders of 25 percent of
the First Mortgage Bonds may declare the principal and interest due on default,
but a majority may annul such declaration if the default has been cured. (See
Mortgage, Section 67.) No holder of First Mortgage Bonds may enforce the lien of
the Mortgage without giving the Mortgage Trustees written notice of a default
and unless holders of 25 percent of the First Mortgage Bonds have requested the
Trustees to act and offered them reasonable opportunity to act and indemnity


                                       9
<PAGE>


satisfactory to the Mortgage Trustees and they shall have failed to act. (See
Mortgage, Section 80.) The holders of a majority of the First Mortgage Bonds may
direct the time, method and place of conducting any proceedings for any remedy
available to the Mortgage Trustees, or exercising any trust or power conferred
upon the Mortgage Trustees, but the Mortgage Trustees are not required to follow
such direction if not sufficiently indemnified for expenditures. (See Mortgage,
Section 71.)

                         DESCRIPTION OF DEBT SECURITIES

     General. The following description sets forth certain general terms and
provisions of Minnesota Power's unsecured debt securities that Minnesota Power
may offer by this prospectus ("Debt Security" or "Debt Securities"). Minnesota
Power will describe the particular terms of the Debt Securities, and provisions
that vary from those described below, in one or more prospectus supplements.

     The Debt Securities will be Minnesota Power's direct unsecured general
obligations. The Debt Securities will be senior debt securities. Minnesota Power
may issue the Debt Securities from time to time in one or more series. Minnesota
Power will issue the Debt Securities under one or more separate Indentures
("Indenture") between Minnesota Power and a trustee ("Indenture Trustee") to be
specified in the prospectus supplement.

     The following descriptions of the Debt Securities and the Indenture are
summaries and are qualified by reference to the Indenture. The form of the
Indenture is being filed as an exhibit to the registration statement, and you
should read the Indenture for provisions that may be important to you.
References to certain sections of the Indenture are included in parentheses.
Whenever particular provisions or defined terms in the Indenture are referred to
under this "Description of Debt Securities," such provisions or defined terms
are incorporated by reference herein. The Indenture will be qualified under the
Trust Indenture Act of 1939. You should refer to the Trust Indenture Act of 1939
for provisions that apply to the Debt Securities.

     The Debt Securities will rank equally with all of Minnesota Power's other
senior, unsecured and unsubordinated debt.

     The prospectus supplement relating to any series of Debt Securities being
offered will include specific terms relating to that offering. These terms will
include any of the following terms that apply to that series:

     o    the title of the Debt Securities;

     o    the total principal amount of the Debt Securities;

     o    the date or dates on which the principal of the Debt Securities will
          be payable and how it will be paid;

     o    the rate or rates at which the Debt Securities will bear interest, or
          how such rate or rates will be determined;

     o    the date or dates from which interest on the Debt Securities will
          accrue, the interest payment dates on which interest will be paid, and
          the record dates for interest payments;

     o    the percentage, if less than 100 percent, of the principal amount of
          the Debt Securities that will be payable if the maturity of the Debt
          Securities is accelerated;

     o    any date or dates on which, and the price or prices at which, the Debt
          Securities may be redeemed at the option of Minnesota Power and any
          restrictions on such redemptions;

     o    any sinking fund or other provisions or options held by holders of
          Debt Securities that would obligate Minnesota Power to repurchase or
          otherwise redeem the Debt Securities;


                                       10
<PAGE>


     o    any changes or additions to the Events of Default under the Indenture
          or changes or additions to the covenants of Minnesota Power under the
          Indenture;

     o    if the Debt Securities will be issued in denominations other than
          $1,000;

     o    if payments on the Debt Securities may be made in a currency or
          currencies other than United States dollars;

     o    any convertible feature or options regarding the Debt Securities;

     o    any rights or duties of another person to assume the obligations of
          Minnesota Power with respect to the Debt Securities;

     o    any collateral, security, assurance or guarantee for the Debt
          Securities;

     o    any rights to change or eliminate any provision of the Indenture or to
          add any new provision to the Indenture without the consent of the
          holders of the securities of such series; and

     o    any other terms of the Debt Securities not inconsistent with the terms
          of the Indenture.

(See Indenture, Section 301.)

     The Indenture does not limit the principal amount of Debt Securities that
may be issued. The Indenture allows Debt Securities to be issued up to the
principal amount that may be authorized by Minnesota Power.

     Debt Securities may be sold at a discount below their principal amount.
United States federal income tax considerations applicable to Debt Securities
sold at an original issue discount may be described in the prospectus
supplement. In addition, certain United States federal income tax or other
considerations applicable to any Debt Securities which are denominated or
payable in a currency or currency unit other than United States dollars may be
described in the prospectus supplement.

     Except as may otherwise be described in the prospectus supplement, the
covenants contained in the Indenture will not afford holders of Debt Securities
protection in the event of a highly-leveraged or similar transaction involving
Minnesota Power or in the event of a change in control.

     Payment and Paying Agents. Except as may be provided in the prospectus
supplement, interest, if any, on each Debt Security payable on each interest
payment date will be paid to the person in whose name such Debt Security is
registered as of the close of business on the regular record date for the
interest payment date. However, interest payable at maturity will be paid to the
person to whom the principal is paid. If there has been a default in the payment
of interest on any Debt Security, the defaulted interest may be paid to the
holder of such Debt Security as of the close of business on a date to be fixed
by the Indenture Trustee, which will be between 10 and 15 days prior to the date
proposed by Minnesota Power for payment of such defaulted interest or in any
other manner permitted by any securities exchange on which such Debt Security
may be listed, if the Indenture Trustee finds it practicable. (See Indenture,
Section 307.)

     Unless otherwise specified in the prospectus supplement, principal of, and
premium, if any, and interest, if any, on the Debt Securities at maturity will
be payable upon presentation of the Debt Securities at the corporate trust
office of the Indenture Trustee, in The City of New York, as Paying Agent for
Minnesota Power. Minnesota Power may change the place of payment on the Debt
Securities, may appoint one or more additional Paying Agents, including
Minnesota Power, and may remove any Paying Agent, all at the discretion of
Minnesota Power. (See Indenture, Section 602.)

     Registration and Transfer. Unless otherwise specified in the prospectus
supplement, the transfer of Debt Securities may be registered, and Debt
Securities may be exchanged for other Debt Securities of the same series of
authorized denominations and with the same terms and principal amount, at the
corporate trust office of the Indenture Trustee in The City of New York.


                                       11
<PAGE>


Minnesota Power may change the place for registration of transfer and exchange
of the Debt Securities and may designate additional places for such registration
and exchange. Unless otherwise provided in the prospectus supplement, no service
charge will be made for any transfer or exchange of the Debt Securities.
However, Minnesota Power may require payment to cover any tax or other
governmental charge that may be imposed. Minnesota Power will not be required to
execute or to provide for the registration of transfer of, or the exchange of,
(a) any Debt Security during a period of 15 days prior to giving any notice of
redemption or (b) any Debt Security selected for redemption except the
unredeemed portion of any Debt Security being redeemed in part. (See Indenture,
Section 305.)

     Satisfaction and Discharge. Minnesota Power will be discharged from its
obligations on the Debt Securities of a particular series, or any portion of the
principal amount of the Debt Securities of such series, if it irrevocably
deposits with the Indenture Trustee sufficient cash or government securities to
pay the principal, or portion of principal, interest, any premium and any other
sums when due on the Debt Securities of such series at their maturity, stated
maturity date, or redemption. (See Indenture, Section 701.)

     The Indenture will be deemed satisfied and discharged when no Debt
Securities remain outstanding and when Minnesota Power has paid all other sums
payable by Minnesota Power under the Indenture. (See Indenture, Section 702.)

     All moneys Minnesota Power pays to the Indenture Trustee or any Paying
Agent on Debt Securities which remain unclaimed at the end of two years after
payments have become due will be paid to or upon the order of Minnesota Power.
Thereafter, the holder of such Debt Security may look only to Minnesota Power
for payment thereof. (See Indenture, Section 603.)

     Limitation on Liens. Unless otherwise specified in a prospectus supplement
with respect to a particular series of Debt Securities, Minnesota Power will not
create or allow any liens, other than permitted liens, to be created on any of
its property, other than excepted property, without making effective provision
whereby:

     o    the outstanding Debt Securities shall be equally and ratably secured;
          or

     o    secured obligations shall be delivered to the Indenture Trustee in an
          amount equal to the outstanding Debt Securities.

The term permitted liens includes, among others:

     o    non-delinquent or contested tax or construction liens;

     o    judgment liens in an aggregate amount less than $10 million or subject
          to appeal;

     o    easements, leases, title defects that do not impair Minnesota Power's
          intended use of property;

     o    governmental rights, mineral, timber or production rights, joint
          ownership rights;

     o    liens fully secured by deposited money or investment securities,
          purchase money liens and liens on property at the time of acquisition;

     o    liens securing tax-exempt financing, non-recourse liens related to the
          acquisition or construction of additional property;

     o    the lien of the Mortgage or any successor indenture secured by First
          Mortgage Bonds; and

     o    any other liens in an aggregate amount not exceeding 2.5 percent of
          Minnesota Power's consolidated assets.

The term excepted property includes, among others:


                                       12
<PAGE>


     o    cash, shares of stock, interests in partnerships, bonds, notes,
          evidence of indebtedness and other securities, including investments
          in its subsidiaries;

     o    contracts, leases, accounts receivable, patents, trademarks,
          intangibles, vehicles, rolling stock, aircraft, inventory;

     o    fuel and other consumables, minerals, timber, natural gas production
          and gathering assets, hydroelectric assets; and

     o    leaseholds.

(See Indenture, Section 608.)

     Consolidation, Merger, and Sale of Assets. Under the terms of the
Indenture, Minnesota Power may not consolidate with or merge into any other
entity or convey, transfer or lease its properties and assets substantially as
an entirety to any entity, unless:

     o    the surviving or successor entity is organized and validly existing
          under the laws of any domestic jurisdiction and it expressly assumes
          Minnesota Power's obligations on all Debt Securities and under the
          Indenture;

     o    immediately after giving effect to the transaction, no Event of
          Default and no event which, after notice or lapse of time or both,
          would become an Event of Default shall have occurred and be
          continuing; and

     o    Minnesota Power shall have delivered to the Indenture Trustee an
          officer's certificate and an opinion of counsel as to compliance with
          the foregoing.

     The terms of the Indenture do not restrict Minnesota Power in a merger in
which Minnesota Power is the surviving entity. (See Indenture, Section 1101.)

     Events of Default. "Event of Default" when used in the Indenture with
respect to any series of Debt Securities, means any of the following:

     o    failure to pay interest, if any, on any Debt Security of the
          applicable series for 30 days after it is due;

     o    failure to pay the principal of or premium, if any, on any Debt
          Security of the applicable series when due, whether at maturity or
          upon earlier redemption;

     o    failure to perform any other covenant in the Indenture, other than a
          covenant that does not relate to that series of Debt Securities, that
          continues for 90 days after Minnesota Power receives written notice
          from the Indenture Trustee, or Minnesota Power and the Indenture
          Trustee receive a written notice from 33 percent of the holders of the
          Debt Securities of such series; however, the Indenture Trustee or the
          Indenture Trustee and the holders of such principal amount of Debt
          Securities of this series can agree to an extension of the 90 day
          period and such an agreement to extend will be automatically deemed to
          occur if Minnesota Power is diligently pursuing action to correct the
          default;

     o    certain events in bankruptcy, insolvency or reorganization of
          Minnesota Power; or

     o    any other event of default included in any supplemental indenture or
          officer's certificate for a specific series of Debt Securities.

(See Indenture, Section 801.)


                                       13
<PAGE>


     The Indenture Trustee may withhold notice to the holders of Debt Securities
of any default, except default in the payment of principal, premium or interest,
if it considers such withholding of notice to be in the interests of the
holders. An Event of Default for a particular series of Debt Securities does not
necessarily constitute an Event of Default for any other series of Debt
Securities issued under the Indenture.

Remedies

     Acceleration of Maturity. If an Event of Default with respect to fewer than
all the series of Debt Securities occurs and continues, either the Indenture
Trustee or the holders of at least 33 percent in principal amount of the Debt
Securities of any such series may declare the entire principal amount of all the
Debt Securities of such series, together with accrued interest, to be due and
payable immediately. However, if the Event of Default is applicable to all
outstanding Debt Securities under the Indenture, only the Indenture Trustee or
holders of at least 33 percent in principal amount of all outstanding Debt
Securities of all series, voting as one class, and not the holders of any one
series, may make such a declaration of acceleration.

     At any time after a declaration of acceleration with respect to the Debt
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained, the Event of Default giving rise to
such declaration of acceleration will be considered waived, and such declaration
and its consequences will be considered rescinded and annulled, if:

     o    Minnesota Power has paid or deposited with the Indenture Trustee a sum
          sufficient to pay:

          (1)  all overdue interest, if any, on all Debt Securities of the
               series;

          (2)  the principal of and premium, if any, on any Debt Securities of
               the series which have otherwise become due and interest, if any,
               that is currently due;

          (3)  interest, if any, on overdue interest; and

          (4)  all amounts due to the Indenture Trustee under the Indenture; or

     o    any other Event of Default with respect to the Debt Securities of that
          series has been cured or waived as provided in the Indenture.

     There is no automatic acceleration, even in the event of bankruptcy,
insolvency or reorganization of Minnesota Power. (See Indenture, Section 802.)

     Right to Direct Proceedings. Other than its duties in case of an Event of
Default, the Indenture Trustee is not obligated to exercise any of its rights or
powers under the Indenture at the request, order or direction of any of the
holders, unless the holders offer the Indenture Trustee a reasonable indemnity.
(See Indenture, Section 903.) If they provide a reasonable indemnity, the
holders of a majority in principal amount of any series of Debt Securities will
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Indenture Trustee, or exercising any power
conferred upon the Indenture Trustee. However, if the Event of Default relates
to more than one series, only the holders of a majority in aggregate principal
amount of all affected series will have the right to give this direction. (See
Indenture, Section 812). The Indenture Trustee is not obligated to comply with
directions that conflict with law or other provisions of the Indenture.

     Limitation on Right to Institute Proceedings. No holder of Debt Securities
of any series will have any right to institute any proceeding under the
Indenture, or to exercise any remedy under the Indenture, unless:

     o    the holder has previously given to the Indenture Trustee written
          notice of a continuing Event of Default;

     o    the holders of a majority in aggregate principal amount of the
          outstanding Debt Securities of all series in respect of which an Event
          of Default shall have occurred and be continuing have made a written


                                       14
<PAGE>


          request to the Indenture Trustee, and have offered reasonable
          indemnity to the Indenture Trustee to institute proceedings; and

     o    the Indenture Trustee has failed to institute any proceeding for 60
          days after notice and has not received any direction inconsistent with
          the written request of holders during such period.

(See Indenture, Section 807.)

     No Impairment of Right to Receive Payment. However, the limitations
described in the preceding paragraph do not apply to a suit by a holder of a
Debt Security for payment of the principal of or premium, if any, or interest,
if any, on a Debt Security on or after the applicable due date. (See Indenture,
Section 808.)

     Annual Notice to Indenture Trustee. Minnesota Power will provide to the
Indenture Trustee an annual statement by an appropriate officer as to Minnesota
Power's compliance with all conditions and covenants under the Indenture. (See
Indenture, Section 606.)

     Modification and Waiver. Minnesota Power and the Indenture Trustee may
enter into one or more supplemental indentures without the consent of any holder
of Debt Securities for any of the following purposes:

     o    to evidence the assumption by any permitted successor of the covenants
          of Minnesota Power in the Indenture and in the Debt Securities;

     o    to add additional covenants of Minnesota Power or to surrender any
          right or power of Minnesota Power under the Indenture;

     o    to add additional Events of Default;

     o    to change, eliminate, or add any provision to the Indenture; provided,
          however, if the change, elimination, or addition will adversely affect
          the interests of the holders of Debt Securities of any series, other
          than any series the terms of which permit such change, elimination or
          addition, in any material respect, such change, elimination, or
          addition will become effective only as to such series:

          (1)  when the consent of the holders of Debt Securities of such series
               has been obtained in accordance with the Indenture; or

          (2)  when no Debt Securities of such series remain outstanding under
               the Indenture;

     o    to provide collateral security for all or part of the Debt Securities;

     o    to establish the form or terms of Debt Securities of any other series
          as permitted by the Indenture;

     o    to provide for the authentication and delivery of bearer securities
          and coupons attached thereto;

     o    to evidence and provide for the acceptance of appointment of a
          successor Indenture Trustee;

     o    to provide for the procedures required for use of a noncertificated
          system of registration for the Debt Securities of all or any series;

     o    to change any place where principal, premium, if any, and interest
          shall be payable, Debt Securities may be surrendered for registration
          of transfer or exchange and notices to Minnesota Power may be served;
          or

     o    to cure any ambiguity or inconsistency or to make any other provisions
          with respect to matters and questions arising under the Indenture;
          provided that such action shall not adversely affect the interests of
          the holders of Debt Securities of any series in any material respect.


                                       15
<PAGE>


(See Indenture, Section 1201.)

     The holders of at least a majority in aggregate principal amount of the
Debt Securities of all series then outstanding may waive compliance by Minnesota
Power with certain restrictive provisions of the Indenture. (See Indenture,
Section 607.) The holders of not less than a majority in principal amount of the
outstanding Debt Securities of any series may waive any past default under the
Indenture with respect to that series, except a default in the payment of
principal, premium, if any, or interest and certain covenants and provisions of
the Indenture that cannot be modified or be amended without the consent of the
holder of each outstanding Debt Security of the series affected. (See Indenture,
Section 813.)

     If the Trust Indenture Act of 1939 is amended after the date of the
Indenture in such a way as to require changes to the Indenture, the Indenture
will be deemed to be amended so as to conform to such amendment of the Trust
Indenture Act of 1939. Minnesota Power and the Indenture Trustee may, without
the consent of any holders, enter into one or more supplemental indentures to
evidence such an amendment. (See Indenture, Section 1201.)

     The consent of the holders of a majority in aggregate principal amount of
the Debt Securities of all series then outstanding is required for all other
modifications to the Indenture. However, if less than all of the series of Debt
Securities outstanding are directly affected by a proposed supplemental
indenture, then the consent only of the holders of a majority in aggregate
principal amount of all series that are directly affected will be required. No
such amendment or modification may:

     o    change the stated maturity of the principal of, or any installment of
          principal of or interest on, any Debt Security, or reduce the
          principal amount of any Debt Security or its rate of interest or
          change the method of calculating such interest rate or reduce any
          premium payable upon redemption, or change the currency in which
          payments are made, or impair the right to institute suit for the
          enforcement of any payment on or after the stated maturity of any Debt
          Security, without the consent of the holder;

     o    reduce the percentage in principal amount of the outstanding Debt
          Securities of any series whose consent is required for any
          supplemental indenture or any waiver of compliance with a provision of
          the Indenture or any default thereunder and its consequences, or
          reduce the requirements for quorum or voting, without the consent of
          all the holders of the series; or

     o    modify certain of the provisions of the Indenture relating to
          supplemental indentures, waivers of certain covenants and waivers of
          past defaults with respect to the Debt Securities of any series,
          without the consent of the holder of each outstanding Debt Security
          affected thereby.

     A supplemental indenture which changes the Indenture solely for the benefit
of one or more particular series of Debt Securities, or modifies the rights of
the holders of Debt Securities of one or more series, will not affect the rights
under the Indenture of the holders of the Debt Securities of any other series.
(See Indenture, Section 1202.)

     The Indenture provides that Debt Securities owned by Minnesota Power or
anyone else required to make payment on the Debt Securities shall be disregarded
and considered not to be outstanding in determining whether the required holders
have given a request or consent. (See Indenture, Section 101.)

     Minnesota Power may fix in advance a record date to determine the required
number of holders entitled to give any request, demand, authorization,
direction, notice, consent, waiver or other such act of the holders, but
Minnesota Power shall have no obligation to do so. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other act of the holders may be given before or after such record date, but
only the holders of record at the close of business on that record date will be
considered holders for the purposes of determining whether holders of the
required percentage of the outstanding Debt Securities have authorized or agreed
or consented to such request, demand, authorization, direction, notice, consent,
waiver or other act of the holders. For that purpose, the outstanding Debt
Securities shall be computed as of the record date. Any request, demand,
authorization, direction, notice, consent, election, waiver or other act of a
holder shall bind every future holder of the same Debt Securities and the holder
of every Debt Security issued upon the registration of transfer of or in
exchange of such Debt Securities. A transferee will be bound by acts of the


                                       16
<PAGE>


Indenture Trustee or Minnesota Power taken in reliance thereon, whether or not
notation of such action is made upon such Debt Security. (See Indenture, Section
104.)

     Resignation of the Indenture Trustee. The Indenture Trustee may resign at
any time by giving written notice to Minnesota Power or may be removed at any
time by act of the holders of a majority in principal amount of all series of
Debt Securities then outstanding delivered to the Indenture Trustee and
Minnesota Power. No resignation or removal of the Indenture Trustee and no
appointment of a successor Indenture Trustee will be effective until the
acceptance of appointment by a successor Indenture Trustee. So long as no Event
of Default or event which, after notice or lapse of time, or both, would become
an Event of Default has occurred and is continuing and except with respect to
the Indenture Trustee appointed by act of the holders, if Minnesota Power has
delivered to the Indenture Trustee a resolution of its Board of Directors
appointing a successor Indenture trustee and such successor has accepted such
appointment in accordance with the terms of the respective Indenture, the
Indenture Trustee will be deemed to have resigned and the successor will be
deemed to have been appointed as Indenture trustee in accordance with such
Indenture. (See Indenture, Section 910.)

     Notices. Notices to holders of Debt Securities will be given by mail to the
addresses of such holders as they may appear in the security register therefor.
(See Indenture, Section 106.)

     Title. Minnesota Power, the Indenture Trustee, and any agent of Minnesota
Power or the Indenture Trustee, may treat the person in whose name Debt
Securities are registered as the absolute owner thereof, whether or not such
Debt Securities may be overdue, for the purpose of making payments and for all
other purposes irrespective of notice to the contrary. (See Indenture, Section
308.)

     Governing Law. Each Indenture and the Debt Securities will be governed by,
and construed in accordance with, the laws of the State of New York. (See
Indenture, Section 112.)

     Regarding the Indenture Trustee. The Indenture Trustee will be specified in
the prospectus supplement. In addition to acting as Indenture Trustee, the
Indenture Trustee may act as trustee under various indentures and trusts of
Minnesota Power and its affiliates.

                              PLAN OF DISTRIBUTION

     Minnesota Power may sell the Securities:

     o    through underwriters or dealers;

     o    through agents; or

     o    directly to one or more purchasers.

     Through Underwriters or Dealers. If Minnesota Power uses underwriters in
the sale, the underwriters will acquire the Securities for their own account.
The underwriters may resell the Securities in one or more transactions,
including negotiated transactions, at a fixed public offering price or at
varying prices determined at the time of sale. The underwriters may sell the
Securities directly or through underwriting syndicates represented by managing
underwriters. Unless otherwise stated in the prospectus supplement relating to
any series of Securities, the obligations of the underwriters to purchase the
Securities will be subject to certain conditions, and the underwriters will be
obligated to purchase all of the Securities if they purchase any of them. If
Minnesota Power uses a dealer in the sale, Minnesota Power will sell the
Securities to the dealer as principal. The dealer may then resell those
Securities at varying prices determined at the time of resale.

     Any initial public offering price and any discounts or concessions allowed
or reallowed or paid to dealers may be changed from time to time.


                                       17
<PAGE>


     Through Agents. Minnesota Power may designate one or more agents to sell
the Securities. Unless stated in a prospectus supplement, the agents will agree
to use their best efforts to solicit purchases for the period of their
appointment.

     Directly. Minnesota Power may sell the Securities directly to one or more
purchasers. In this case, no underwriters or agents would be involved.

     General Information. A prospectus supplement will state the name of any
underwriter, dealer or agent and the amount of any compensation, underwriting
discounts or concessions paid, allowed or reallowed to them. A prospectus
supplement will also state the proceeds to Minnesota Power from the sale of the
Securities, any initial public offering price and other terms of the offering of
the Securities.

     Minnesota Power may authorize agents, underwriters or dealers to solicit
offers by certain institutions to purchase the Securities from Minnesota Power
at the public offering price and on terms described in the related prospectus
supplement pursuant to delayed delivery contracts providing for payment and
delivery on a specified date in the future.

     Minnesota Power may have agreements to indemnify agents, underwriters and
dealers against certain civil liabilities, including liabilities under the
Securities Act of 1933.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 302A.521 of the Minnesota Business Corporation Act generally
provides for the indemnification of directors, officers or employees of a
corporation made or threatened to be made a party to a proceeding by reason of
the former or present official capacity of the person against judgments,
penalties and fines (including attorneys' fees and disbursements) where such
person, among other things, has not been indemnified by another organization,
acted in good faith, received no improper personal benefit and with respect to
any criminal proceeding, had no reasonable cause to believe his conduct was
unlawful.

     Article IX of the Articles of Incorporation of Minnesota Power contains the
following provision:

     "No director of this Corporation shall be personally liable to this
     Corporation or its stockholders for monetary damages for breach of
     fiduciary duty by that director as a director; provided, however, that this
     Article IX shall not eliminate or limit the liability of a director: (a)
     for any breach of the director's duty of loyalty to this Corporation or its
     stockholders; (b) for acts or omissions not in good faith or that involve
     intentional misconduct or a knowing violation of the law; (c) under
     Minnesota Statutes Section 302A.559 or 80A.23; (d) for any transaction from
     which the director derived an improper personal benefit; or (e) for any act
     or omission occurring prior to the date when this Article IX becomes
     effective. If, after the stockholders approve this provision, the Minnesota
     Business Corporation Act, Minnesota Statutes Chapter 302A, is amended to
     authorize corporate action further eliminating or limiting the personal
     liability of directors, then the liability of a director of this
     Corporation shall be deemed eliminated or limited to the fullest extent
     permitted by the Minnesota Business Corporation Act, as so amended. No
     amendment to or repeal of this Article IX shall apply to or have any affect
     on the liability or alleged liability of any director of this Corporation
     for or with respect to any acts or omissions of such director occurring
     prior to that amendment or repeal."

     Section 13 of the Bylaws of Minnesota Power contains the following
provisions relative to indemnification of directors and officers:

     "The Corporation shall reimburse or indemnify each present and future
     Director and officer of the Corporation (and his or her heirs, executors
     and administrators) for or against all expenses reasonably incurred by such
     Director or officer in connection with or arising out of any action, suit
     or proceeding in which such Director or officer may be involved by reason
     of being or having been a Director or officer of the Corporation. Such
     indemnification for reasonable expenses is to be to the fullest extent
     permitted by the Minnesota Business Corporation Act, Minnesota Statutes
     Chapter 302A. By affirmative vote of the Board of Directors or with written
     approval of the Chairman and Chief Executive Officer, such indemnification
     may be extended to include agents and employees who are not Directors or


                                      II-1
<PAGE>


     officers of the Corporation, but who would otherwise be indemnified for
     acts and omissions under Chapter 302A of the Minnesota Business Corporation
     Act, if such agent or employee were an officer of the Corporation."

     "Reasonable expenses may include reimbursement of attorneys' fees and
     disbursements, including those incurred by a person in connection with an
     appearance as a witness."

     "Upon written request to the Corporation and approval by the Chairman and
     Chief Executive Officer, an agent or employee for whom indemnification has
     been extended, or an officer or Director may receive an advance for
     reasonable expenses if such agent, employee, officer or Director is made or
     threatened to be made a party to a proceeding involving a matter for which
     indemnification is believed to be available under Minnesota Statutes
     Chapter 302A."

     "The foregoing rights shall not be exclusive of other rights to which any
     Director or officer may otherwise be entitled and shall be available
     whether or not the Director or officer continues to be a Director or
     officer at the time of incurring such expenses and liabilities."

     Minnesota Power has insurance covering its expenditures which might arise
in connection with the lawful indemnification of its directors and officers for
their liabilities and expenses, and insuring officers and directors of Minnesota
Power against certain other liabilities and expenses.

ITEM 17.  UNDERTAKINGS.

a.   The undersigned registrant hereby undertakes:

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

          (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

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

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

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the SEC
by the registrant pursuant to Section 13 or Section 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in the 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.


                                      II-5
<PAGE>


     (4)  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 the 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.

b.   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 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 Securities Act of
1933 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 controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

                                POWER OF ATTORNEY

     Each person whose signature appears below hereby authorizes any agent for
service named in this registration statement to execute in the name of each such
person, and to file with the SEC, any and all amendments, including
post-effective amendments, to this registration statement, and appoints any such

individually and in each capacity stated below and file any such amendments to
this registration statement and the registrant hereby also appoints each such
agent for service as its attorney-in-fact with like authority to sign and file
any such amendments in its name and behalf.

                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the registrant

fully-registered form without coupons, registered in such names and in such

Company shall have the right to deliver the Securities registered in the name of

          3. Registration Statement and Prospectus; Public Offering. The Company
             ------------------------------------------------------
has filed with the Securities and Exchange Commission (the "Commission"),
pursuant to the provisions of the Securities Act of 1933, as amended (the
"Securities Act"), and the published rules and regulations adopted by the
Commission under it (the "Rules and Regulations"), a registration statement on
Form S-3, including a prospectus ("Registration Statement No. 333-[      ]"),
                                                                   ------
relating to the registration of $   ,000,000 principal amount of its First
                                 ---
Mortgage Bonds and Debt Securities, and such registration statement was declared
effective on [           , 2000]. The term "preliminary prospectus" means any
              -----------
preliminary prospectus (as referred to in Rule 430 of the Rules and Regulations)
included at any time as a part of the Registration Statement. Copies of such
registration statement and any amendments thereto and of each preliminary
prospectus included as part of Registration Statement No. 333-[______] have been
delivered to the Underwriter. Registration Statement No. 333-[______], as it may
be amended to the date of this Agreement, including financial statements and all
exhibits, and the prospectus, as supplemented by a prospectus supplement
relating to the Securities, proposed to be filed pursuant to Rule 424 is
hereinafter respectively called the "Registration Statement" and the
"Prospectus." References herein to the term "Effective Date" shall be deemed to
refer to the later of the time and date the Registration Statement was declared
effective or the time and date of the filing of the Company's most recent Annual
Report on Form 10-K if such filing is made prior to the Closing Date. Any
reference herein to the Registration Statement, any preliminary prospectus or
the Prospectus includes the documents incorporated by reference (the
"Incorporated Documents") therein pursuant to Item 12 of Form S-3 under the
Securities Act and filed under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), on or before the Effective Date or date of such
preliminary prospectus or the Prospectus, as the case may be, and any reference
herein to "amend," "amendment" or "supplement" with respect to the Registration
Statement, any preliminary prospectus or the Prospectus includes the filing of
any document under the Exchange Act after the Effective Date or the date of any
preliminary prospectus or the Prospectus, as the case may be, and incorporated
in such document by reference if such filing is made prior to the Closing Date.

          The Company understands that the Underwriter proposes to make a public
offering of the Securities, as described in the Prospectus, as soon after the
date of this Agreement as the Underwriter deems advisable. The Company confirms
that the Underwriter and dealers have been authorized to distribute each
preliminary prospectus, if any, and are authorized to distribute the Prospectus
and any amendments or supplements to it.

          4. Representations of the Company. The Company represents to the
             ------------------------------
Underwriter as follows:

          (a) The Company meets the requirements for use of Form S-3 under the

Statement and, at the date of the filing of the Prospectus, and at the Closing
Date, the Prospectus, as each may be amended or supplemented, and the
[1 Mortgage] [2 Indenture] fully complied or will fully comply in all material
respects with the applicable provisions of the Securities Act, the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"), and the Rules and
Regulations, or pursuant to the Rules and Regulations will be deemed to comply
therewith; on said Effective Date and Closing Date the Registration Statement,
as it may be amended or supplemented, did not and will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading; on
said date of filing of the Prospectus and the Closing Date, the Prospectus, as
it may be amended or supplemented, will not contain an untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; and on said date of filing of the Prospectus and the
Closing Date, the Incorporated Documents will fully comply in all material
respects with the applicable provisions of the Exchange Act and the rules and
regulations of the Commission under the Exchange Act (the "Exchange Act Rules
and Regulations"), and, when read together with the Prospectus, as it may be
amended or supplemented, will not contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading; except that this representation does
not apply to (1) statements or omissions made in reliance on and in conformity
with information relating to the Underwriter furnished in writing to the Company
by the Underwriter expressly for use in the Registration Statement or the
Prospectus, as they may be amended or supplemented or (2) the portion of the
Registration Statement constituting the respective Statements of Eligibility, or
amendments thereto, of The Bank of New York and Douglas J. MacInnes, as
Trustees, with respect to the Mortgage, or the portion of the Registration
Statement constituting the Statement of Eligibility, or amendments thereto, of
[               ], with respect to the Indenture, under the Trust Indenture Act
 ---------------
except statements or omissions made in reliance on and in conformity with
information furnished in writing to the Trustee by or on behalf of the Company
for use in such Statements of Eligibility or any amendments thereto. For

preliminary prospectus, any preliminary prospectus supplement, the Registration
Statement or the Prospectus.

          (c) The Company and its Material Subsidiaries (as defined below) have
good and sufficient title to all real material property and good and sufficient
title to all material personal property owned by them, in each case free and
clear of all liens, encumbrances and defects except such as are described in the
Prospectus or such as do not materially interfere with the use made and proposed
to be made of such property by the Company and its Material Subsidiaries; and
any material real property and buildings held under lease by the Company and its
Material Subsidiaries are held by them under valid, subsisting and enforceable
leases with such exceptions as are not material and do not materially interfere
with the use made and proposed to be made of such property and buildings by the
Company and its Material Subsidiaries (as used in this Agreement, the term
"Material Subsidiary" means a significant subsidiary under Rule 1-02(w) of
Regulation S-X of the Commission).

          (d) The Company has been duly incorporated and is validly existing as
a corporation in good standing under the laws of Minnesota, with power and
authority (corporate and other) to own its properties and conduct its business
as described in the Prospectus, and there is no jurisdiction wherein the
character of the properties owned or held under lease by the Company or the
nature of the business transacted by the Company would expose the Company to any
material liability or disability by reason of the failure to qualify the Company
as a foreign corporation in any such jurisdiction; and each Material Subsidiary
of the Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of its jurisdiction of
incorporation, and there is no jurisdiction wherein the character of the
properties owned or held under lease by any Material Subsidiary or the nature of
the business transacted by such Material Subsidiary would expose such Material
Subsidiary to any material liability or disability by reason of the failure to
qualify such Material Subsidiary as a foreign corporation in any such
jurisdiction.

          (e) Since the respective dates as of which information is given in the
Registration Statement and the Prospectus, as they may be amended or
supplemented, there has not been any material adverse change in the management,
business, properties, financial condition or results of operations of the
Company and its subsidiaries taken as a whole, and there has not been any
material transaction entered into by the Company or its Material Subsidiaries,
other than transactions in the ordinary course of business and transactions set
forth in or contemplated by the Registration Statement and the Prospectus, as
they may be amended or supplemented, which is material to the Company and its
subsidiaries, taken as a whole. The Company and its Material Subsidiaries have
no contingent obligation which is not disclosed in the Registration Statement
and the Prospectus, as they may be amended or supplemented, which is material to
the Company and its subsidiaries, taken as a whole.

          (f) Any Incorporated Documents filed and incorporated by reference
prior to the Closing Date will, when they are filed with the Commission, conform
in all material respects with the requirements of the Exchange Act and the
Exchange Act Rules and Regulations.

          (g) The Company has full corporate power and authority to enter into
this Agreement. This Agreement has been duly authorized, executed and delivered
by the Company and is a valid and binding agreement of the Company enforceable
against it in accordance with its terms.

          (h) The performance of this Agreement and the consummation of the
transactions contemplated hereby this Agreement and the fulfillment of its terms
will not result in a breach of any of the terms or provisions of, or constitute
a default under, any indenture, mortgage, deed of trust, or other material
agreement or instrument to which the Company is now a party.

          (i) The statements set forth in the Prospectus under the captions
[1 "Description of New Bonds" and "Certain Terms of the Offered Bonds."]
[2 "Description of the Debt Securities" and "Certain Terms of the Offered Debt
Securities"] constitute a summary of the securities, documents and instruments
therein described, are accurate and fairly present the information contained
therein in all material respects.

          (j) The Securities, when issued and delivered as provided in this
Agreement, will constitute legal, valid and binding obligations of the Company
in accordance with their terms except as the same (1) may be subject to


- ------------------------
1    For use in connection with First Mortgage Bond.
2    For use in connection with Debt Securities.


                                       4

bankruptcy, insolvency, reorganization, moratorium or other laws relating to or
affecting the enforcement of creditors' rights and (2) may be limited by general
principles of equity (whether such enforceability is considered in a proceeding
in equity or in law).

          (k) The description of the Securities in the Registration Statement
and the Prospectus, as they may be amended or supplemented, is, and at the
Closing Date will be, complete and accurate in all respects.

          (l) The Company has filed a Petition for Certification of Capital
Structure with the Minnesota Public Utilities Commission ("Minnesota
Commission") pursuant to the Minnesota Public Utilities Act with respect to the
issuance and sale by the Company of the Securities. The Minnesota Commission has
entered an authorizing order approving the capital structure including the
issuance and sale of the Securities. Apart from such authorizing order of the
Minnesota Commission, no consent, approval, authorization or order of, or any
filing or declaration with, any court or governmental agency or body is required
for the consummation by the Company of the transactions on its part herein
contemplated, except such as have been obtained under the Securities Act or the
Rules and Regulations.

          (m) The Company is not, and after giving effect to the offering and
sale of the Securities will not be, an "investment company", as such term is
defined in the Investment Company Act of 1940, as amended.

          (n) Except as set forth in the Registration Statement and the
Prospectus, there are no legal or governmental proceedings pending to which the
Company or any of its Material Subsidiaries is a party or to which any property
of the Company or any of its Material Subsidiaries is subject, which, if
determined adversely to the Company or any of its Material Subsidiaries would in
the Company's reasonable judgment individually or in the aggregate have a
material adverse effect on the management, business, properties, financial
condition or results of operations of the Company and its subsidiaries taken as
a whole; and, to the best of the Company's knowledge, no such proceedings are
threatened or contemplated by governmental authorities or threatened by others.

          5. Agreements of the Company. (a) The Company will not file any
             -------------------------
amendment or supplement to the Registration Statement or the Prospectus unless a
copy has first been submitted to the Underwriter a reasonable time before its
filing and the Underwriter has not reasonably objected to it in writing within a
reasonable time after receiving the copy.

          (b) The Company will promptly advise the Underwriter (i) of the
initiation or threatening of any proceedings for, or receipt by the Company of
any notice with respect to, the suspension of the qualification of the
Securities for sale in any jurisdiction or the issuance of any order by the
Commission suspending the effectiveness of the Registration Statement and (ii)
of receipt by the Company or any representative or attorney of the Company of
any other communication from the Commission relating to the Company, the
Registration Statement, any preliminary prospectus or the Prospectus or to the
transactions contemplated by this Agreement. The Company will make every
reasonable effort to prevent the issuance of an order suspending the
effectiveness of the Registration Statement and, if any such order is issued, to
obtain its lifting as soon as possible.


                                       5
<PAGE>


          (c) The Company will furnish to the Underwriter without charge one
signed copy, or one conformed copy certified by an officer of the Company, of
each of the Registration Statement and of any amendments thereto (including all
exhibits filed with any such document) and as many conformed copies of the
Registration Statement as the Underwriter may reasonably request.

          (d) During such period as a prospectus is required by law to be
delivered by the Underwriter or a dealer, the Company will deliver, without
charge, to the Underwriter and to dealers, at such office or offices as the
Underwriter may designate, as many copies of the Prospectus as the Underwriter
may reasonably request, and, during such period (not exceeding nine months)
after the Effective Date if any event occurs as a result of which it is
necessary to amend or supplement the Prospectus in order to make the statements
in it, in the light of the circumstances existing when the Prospectus is
delivered to a purchaser, not misleading in any material respect, or if during
such period it is necessary to amend or supplement the Prospectus to comply with
the Securities Act or the Rules and Regulations, the Company will promptly
prepare, submit to the Underwriter, file, subject to paragraph (a) of this
Section, with the Commission and deliver, without charge, to the Underwriter and
to dealers (whose names and addresses the Underwriter will furnish to the
Company) to whom Securities may have been sold by the Underwriter, and to other
dealers on request, amendments or supplements to the Prospectus so that the
statements in the Prospectus, as so amended or supplemented, will not, in the
light of the circumstances existing when the Prospectus is delivered to a
purchaser, be misleading in any material respect and will comply with the
Securities Act and the Rules and Regulations; provided that should such event
relate solely to the activities of the Underwriter, then the Underwriter shall
assume the expense of preparing and furnishing any such amendment or supplement.
In case the Underwriter is required to deliver a Prospectus after the expiration
of nine months from the Effective Date, the Company, upon the request of the
Underwriter, will furnish to the Underwriter, at the expense of the Underwriter,
a reasonable quantity of an amendment or supplement complying with Section 10(a)
of the Securities Act. Delivery by the Underwriter of any such amendments or
supplements to the Prospectus will not constitute a waiver of any of the
conditions in Section 6.

          (e) The Company will make generally available to the Company's
security holders, as soon as practicable but in no event later than the last day
of the 15th full calendar month following the calendar quarter in which the
Effective Date falls, an earnings statement satisfying the provisions of Section
11(a) of the Securities Act and Rule 158 of the Rules and Regulations.

          (f) The Company will take such actions as the Underwriter reasonably
designates in order to qualify the Securities for offer and sale under the
securities or "blue sky" laws of such jurisdictions as the Underwriter
reasonably designates.

          (g) The Company will pay, or reimburse if paid by the Underwriter,
whether or not the transactions contemplated by this Agreement are consummated
or this Agreement is terminated, all costs and expenses incident to the
performance of the obligations of the Company under this Agreement, including
costs and expenses relating to (i) the preparation, printing and filing of the
Registration Statement and exhibits thereto, each preliminary prospectus, the
Prospectus, all amendments and supplements to the Registration Statement and the

delivery of it to the Trustees, in the counties where the mortgaged property of
the Company is located,] (ii) the authorization and issuance of the Securities
and the preparation and delivery of the forms of the Securities sold by the
Company to the Underwriter, (iii) the registration or qualification of the
Securities for offer and sale under the securities or "blue sky" laws of the
jurisdictions referred to in Section 5(f) and the determination of the legality
of the Securities for investment, including the reasonable fees and
disbursements of counsel for the Underwriter (not to exceed $     ) in that
                                                             -----
connection, and the preparation and printing of preliminary and supplemental
"blue sky" memoranda and legal investment memoranda, (iv) except as provided in
Section 5(d), the furnishing (including costs of shipping and mailing) to the
Underwriter and to dealers of copies of the Registration Statement, each
preliminary prospectus, the Prospectus, and all amendments or supplements to the
Prospectus, and of the other documents required by this Section to be so
furnished, (v) any fees charged by securities rating services for rating the
Securities, (vi) all transfer taxes, if any, with respect to the sale and
delivery of the Securities by the Company to the Underwriter, and (vii) the fees
and expenses of the Trustees, and Paying Agent or Registrar under the
[1         ] Supplemental Indenture] [2             ] and the reasonable fees
  ---------                            -------------
and disbursements of counsel for any Trustee in connection with the
[1[         ] Supplemental Indenture] [2             ] or the Securities.
   ---------                            -------------

          6. Conditions of the Underwriter's Obligation. The obligation of the
             ------------------------------------------
Underwriter to purchase the Securities is subject to the accuracy, on the date
of this Agreement and on the Closing Date, of the representations of the Company
in this Agreement, to the accuracy and completeness of all statements made by

have been made.

          (b) No stop order suspending the effectiveness of the Registration

          (c) Since the respective dates as of which such information is given

supplemented, (i) there must not have been any material change in the capital
stock or long-term debt of the Company and its subsidiaries, taken as a whole,
(ii) there must not have been any material adverse change in the management,

                                       7
<PAGE>


or incorrect in any material respect any statement or information contained in
the Prospectus or that is not reflected in the Prospectus but should be
reflected in it in order to make the statements or information in it not
misleading in any material respect; and in the judgment of the Underwriter, any
such development referred to in clause (i), (ii) or (iii) makes it impracticable
to consummate the sale and delivery of the Bonds by the Underwriter at the
initial public offering price.

          (d) The Underwriter must receive on the Closing Date a certificate,
dated such date, of the chief executive officer, the chief operating officer or
the chief financial officer of the Company certifying that (i) the signer has

effectiveness of the Registration Statement or prohibiting the sale of the
Securities has been issued and no proceedings for such purpose are pending
before or threatened by the Commission, (v) there has been no document required
to be filed under the Exchange Act and the Exchange Act Rules and Regulations
that upon such filing would be deemed to be an Incorporated Document that has
not been so filed, and (vi) the Company has performed all agreements that this

          (e) Since the date of this Agreement, there must not have been any
decreases in the rating of the Company's Securities by Moody's Investors
Service, Inc. or Standard & Poor's Rating Services.

          (f) The Underwriter must receive on the Closing Date opinions dated
the Closing Date substantially in the form of Annex A and B to this Agreement
from Thelen Reid & Priest LLP, counsel to the Company, and Philip R. Halverson,
Esq., general counsel of the Company, respectively.

          (g) The Underwriter must receive on the Closing Date from Morrison
Cohen Singer & Weinstein, LLP, its counsel, an opinion dated the Closing Date
with respect to the Company, the Securities, the Registration Statement, the
Prospectus, the [1[        ] Supplemental Indenture] [2                  ], this
                   --------                            ------------------
Agreement and the form and sufficiency of all proceedings taken in connection
with the sale and delivery of the Securities. Such opinion and proceedings shall
be satisfactory in all respects to the Underwriter. The Company must have
furnished to such counsel such documents as they may reasonably request for the
purpose of enabling them to render such opinion.

          (h) The Underwriter must receive on the Closing Date a signed letter,
dated the Closing Date, from PricewaterhouseCoopers LLP to the effect that (i)
they are independent public accountants with respect to the Company within the
meaning of the Securities Act and the applicable published rules and regulations
thereunder, (ii) in their opinion, the consolidated financial statements audited


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

by them and incorporated by reference in the Prospectus comply as to form in all
material respects with the applicable accounting requirements of the Securities
Act and the Exchange Act and the published rules and regulations thereunder with
respect to registration statements on Form S-3, (iii) on the basis of a reading
of the unaudited consolidated financial statements of the Company incorporated
by reference in the Prospectus, the latest available unaudited consolidated
financial data of the Company since the close of the Company's most recent
audited fiscal year, the minutes and consents of the Board of Directors since
the end of the most recent audited fiscal year, and inquiries of officials of
the Company who have responsibility for financial and accounting matters (it
being understood that the foregoing procedures do not constitute an audit made
in accordance with generally accepted auditing standards and would not
necessarily reveal matters of significance with respect to the comments made in
such letter, and, accordingly, that PricewaterhouseCoopers LLP makes no
representations as to the sufficiency of such procedures for the Underwriter's
purposes), nothing has come to their attention which caused them to believe that
(1) the unaudited consolidated financial statements of the Company incorporated
by reference in the Prospectus (a) do not comply as to form in all material
respects with the applicable accounting requirements of the Exchange Act as it
applies to Form 10-Q and the published rules and regulations thereunder or (b)
are not stated on a basis substantially consistent with that of the audited
consolidated financial statements of the Company incorporated by reference in
the Prospectus, (2) at the date of the latest available unaudited financial data
read by them and at a specified date not more than five days prior to the
Closing Date there was any change in the capital stock or long-term debt of the
Company and its subsidiaries, or any decrease in the Company's consolidated net
current assets or shareholders' equity, in each case as compared with amounts
shown in the most recent consolidated financial information incorporated by
reference in the Prospectus, except in all instances for changes or decreases
which the Prospectus, as amended or supplemented, discloses have occurred or may
occur, or which are disclosed in such letter, or (3) for the period from the
date of the most recent audited consolidated financial statements to the date of
the latest available unaudited financial data read by them and for the period
from the date of the latest available unaudited financial data read by them to a
specified date not more than five days prior to the Closing Date, there were any
decreases, as compared with the corresponding period in the preceding year, in
consolidated operating revenues or in the total or per average share amounts of
net income, except in all instances for decreases which the Prospectus, as
amended or supplemented, discloses have occurred or may occur, or which are
disclosed in such letter, and (4) they have carried out certain procedures and
made certain findings, as specified in such letter, with respect to certain
amounts included or incorporated by reference in the Registration Statement and
the Prospectus and such other items as the Underwriter may reasonably request.

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement will comply with this Agreement only if they are in
form and scope satisfactory to counsel for the Underwriter.

          7. Indemnification. (a) The Company shall indemnify and hold harmless
             ---------------
the Underwriter, the directors, officers, employees and agents of the
Underwriter, and each person, if any, who controls the Underwriter, within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act,
against any and all losses, claims, damages and liabilities, joint or several
(including, as and when incurred, any investigative, legal or other expenses
reasonably incurred in connection with, and any amount paid in settlement of,
any action, suit or proceeding or any claim asserted), to which they, or any of


                                       9
<PAGE>


them, may become subject under the Securities Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities arise out of or are based
on any untrue statement or alleged untrue statement of a material fact contained
in any preliminary prospectus, the Registration Statement or the Prospectus or
any amendment or supplement to the Registration Statement or the Prospectus
(including any Incorporated Document), or the omission or alleged omission to
state in it a material fact required to be stated in it or necessary to make the
statements in it not misleading; provided, however, that the Company will not be
liable to the extent that such loss, claim, damage, or liability arises from the
sale of the Securities in the public offering to any person by the Underwriter
and is based on an untrue statement or omission or alleged untrue statement or
omission (1) made in reliance on and in conformity with information furnished in
writing to the Company by the Underwriter expressly for use in the Registration
Statement or the Prospectus or (2) in a preliminary prospectus if the Prospectus
corrects the untrue statement or omission or alleged untrue statement or
omission which is the basis of the loss, claim, damage or liability for which
indemnification is sought and a copy of the Prospectus was not sent or given to
such person at or before the confirmation of the sale to such person in any case
where such delivery is required by the Securities Act, unless such failure to
deliver the Prospectus was a result of noncompliance by the Company with Section
5(d). This indemnity agreement will be in addition to any liability that the
Company might otherwise have.

          (b) The Underwriter shall indemnify and hold harmless the Company, its
officers and directors, and each person, if any, who controls any thereof within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act, to the same extent as the foregoing indemnity from the Company to the
Underwriter, but only insofar as losses, claims, damages or liabilities arise
out of or are based on any untrue statement or omission or alleged untrue
statement or omission made in or in reliance on and in conformity with
information furnished in writing to the Company by the Underwriter expressly for
use in the Registration Statement or the Prospectus , as set forth in the last
sentence of Section 4(b). This indemnity agreement will be in addition to any
liability that the Underwriter might otherwise have.

          (c) Any party that proposes to assert the right to be indemnified
under this Section 7 will, promptly after receipt of notice of commencement of
any action against such party in respect of which a claim is to be made against
an indemnifying party or parties under this Section 7, notify in writing each
such indemnifying party of the commencement of such action, enclosing a copy of
all papers served, but the omission so to notify such indemnifying party will
not relieve it from any liability that it may have to any indemnified party
otherwise than under this Section 7. If any such action is brought against any
indemnified party and it notifies the indemnifying party of its commencement,
the indemnifying party will be entitled to participate in, and, to the extent
that it elects by delivering written notice to the indemnified party promptly
after receiving notice of the commencement of the action from the indemnified
party, jointly with any other indemnifying party similarly notified, to assume
the defense of the action, with counsel satisfactory to the indemnified party,
and, after notice from the indemnifying party to the indemnified party of its
election to assume the defense, the indemnifying party will not be liable to the
indemnified party for any legal or other expenses except as provided below and
except for the reasonable costs of investigation subsequently incurred by the
indemnified party in connection with the defense. The indemnified party will
have the right to employ its counsel in any such action, but the fees and


                                       10
<PAGE>


expenses of such counsel will be at the expense of such indemnified party unless
(i) the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (ii) the indemnified party has been advised
by such counsel employed by it that there may be legal defenses available to it
involving potential conflict with the interests of an indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (iii) the indemnifying
party has not in fact employed counsel to assume the defense of such action
within a reasonable time after receiving notice of the commencement of the
action, in each of which cases the fees and expenses of counsel will be at the
expense of the indemnifying party or parties. It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements and other charges of more than one separate counsel admitted to
practice in such jurisdiction at any one time for all such indemnified party or
parties. All such fees, disbursements and other charges will be reimbursed by
the indemnifying party promptly as they are incurred. An indemnifying party will
not be liable for any settlement of any action or claim effected without its
written consent (which consent will not be unreasonably withheld). No
indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (ii) does not include a statement as to, or an admission of, fault,
culpability or a failure to act, by or on behalf of any indemnified party.

          8. Contribution. In order to provide for just and equitable
             ------------
contribution in the circumstances in which the indemnification provided for
under the foregoing provisions of Section 7 is applicable in accordance with its
terms but for any reason is held to be unavailable from the Company or the
Underwriter, the Company and the Underwriter shall contribute to the amount paid
or payable as a result of losses, claims, liabilities, expenses and damages
(including any investigative, legal and other expenses reasonably incurred in
connection with, and any amount paid in settlement of, any action, suit or
proceeding or any claim asserted) to which the Company and the Underwriter may
be subject in such proportion as shall be appropriate to reflect (i) the
relative benefits received by the Company on the one hand and the Underwriter on
the other, (ii) the relative fault of the Company, on the one hand, and the
Underwriter, on the other, with respect to the statements or omissions which
resulted in such loss, claim, liability, expense or damage, or action in respect
thereof, as well as (iii) any other relevant equitable considerations with
respect to such offering. Such relative benefits shall be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Company bear to the total underwriting discounts and commissions received
by the Underwriter as set forth in the Prospectus. Such relative fault shall be
determined by reference, among other things, to whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company or by the
Underwriter, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriter agree that it would not be just and equitable if
contributions pursuant to this Section 8 were to be determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to herein. The amount paid or payable by


                                       11
<PAGE>


an indemnified party as a result of the loss, claim, liability, expense or
damage, or action in respect thereof, referred to above in this Section 8 shall
be deemed to include, for purpose of this Section 8, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 8, the Underwriter shall not be required to contribute any amount in
excess of the underwriting discounts received by it, except that insofar as
losses, claims, damages and liabilities arise from the sale of the Securities in
the public offering to any person by the Underwriter and are based on any untrue
statement or omission or alleged untrue statement or omission made in or in
reliance on and in conformity with information furnished in writing to the
Company by the Underwriter expressly for use in the Registration Statement, any
preliminary prospectus or preliminary prospectus supplement or the Prospectus,
as set forth in the last sentence of Section 4(b), the Underwriter shall not be
required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which the
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person found guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 8, any person who
controls a party to this Agreement within the meaning of the Act will have the
same rights to contribution as that party, and each officer of the Company who
signed the Registration Statement will have the same rights to contribution as
the Company, subject in each case to the provisions hereof. Any party entitled
to contribution, promptly after receipt of notice of commencement of any action
against such party in respect of which a claim for contribution may be made
under this Section 8, will notify any such party or parties from whom
contribution may be sought, but the omission so to notify will not relieve the
party or parties from whom contribution may be sought from any other obligation
it or they may have under this Section 8. No party will be liable for
contribution with respect to any action or claim settled without its written
consent (which consent will not be unreasonably withheld).

          9. Termination. This Agreement may be terminated by the Underwriter by
             -----------
notifying the Company at any time

                    (a) on or before the Closing Date if, in the judgment of the
          Underwriter, payment for the delivery of the Securities is rendered
          impracticable or inadvisable because (1) trading in the equity
          securities of the Company is suspended by the Commission or by the New
          York Stock Exchange, (2) additional material governmental
          restrictions, not in force on the date of this Agreement, are imposed
          upon trading in securities generally or minimum or maximum prices have
          been generally established on the New York Stock Exchange or on the
          American Stock Exchange, or trading in securities generally has been
          suspended or limited on either such Exchange or a general banking
          moratorium has been established by Federal or New York authorities, or
          (3) any outbreak or material escalation of hostilities or other
          calamity or crisis occurs the effect of which is such as to make it
          impracticable to market the Securities, or

                    (b) at or before the Closing Date, if any of the conditions
          specified in Section 6 have not been fulfilled when and as required by
          this Agreement.

Dear Sirs:

          Reference is made to the sale by Minnesota Power, Inc. ("Company") of
[$        ] principal amount of its [1 First Mortgage Bonds,   % Series Due
  --------                                                  --

Series Due [           , 20  ] (the "Debt Securities" or the "Securities")].
            -----------    --
[1 The Bonds will be issued under the Company's Mortgage and Deed of Trust,
dated as of September 1, 1945, to Irving Trust Company (now The Bank of New
York) and Richard H. West (Douglas J. MacInnes, successor), as Trustees, as
amended and supplemented by all indentures supplemental thereto,
including a [            ] Supplemental Indenture thereto dated as of
             ------------
[            , 200 ] (said Mortgage and Deed of Trust, as so supplemented,
 ------------     -
being hereinafter called the "Mortgage")]. [2 The Debt Securities will be
issued under the Company's Indenture (For Unsecured Debt Securities,
dated as of [            , 200 ] to The Bank of New York, as Trustee, as
             ------------     -
                                       ]. We advise you that we have acted as
- ---------------------------------------
counsel to the Company in connection with such issuance and sale and have
participated in the preparation of (a) [1 the Mortgage] [2 the Indenture]; (b)
Registration Statement No. 333-[      ], as filed by the Company with the
                                ------
Securities and Exchange Commission for the registration of the Company's First
Mortgage Bonds and Debt Securities under the Securities Act of 1933, as amended
(the "Securities Act"), and for the qualification under the Trust Indenture Act
of 1939, as amended (the "Trust Indenture Act") of the Mortgage and of the
Indenture (such registration statement, as amended at the Effective Date (as
such term is defined in the Agreement referred to below), being hereinafter
referred to as the "Registration Statement"); (c) the prospectus constituting
part of the Registration Statement, as amended and supplemented by a prospectus
supplement relating to the Securities ("Prospectus"); and (d) the Underwriting
Agreement dated [             , 200 ] between the Company and you ("Agreement").
                 -------------     -
In addition, we have reviewed the petition filed by the Company with the
Minnesota Public Utilities Commission seeking authorization to issue the
Securities, and the order issued by said Commission in response to said
petition.

          We have reviewed all corporate proceedings taken by the Company in
respect of the authorization of the [1 Mortgage] [2 Indenture] and the issuance
and sale of the Securities thereunder.

2    For use in connection with Debt Securities.


<PAGE>


          Upon the basis of our familiarity with these transactions, we are of
the opinion that:

          1. The [1 Mortgage] [2 Indenture] has been duly and validly authorized
by all necessary corporate action, has been duly and validly executed and
delivered, and is a valid and binding mortgage of the Company enforceable in
accordance with its terms, except as limited or affected by bankruptcy,
insolvency, reorganization, receivership, moratorium or other laws affecting
enforcement of [1mortgagees' and] other creditors' rights and remedies generally
and general principles of equity.

          2. The Securities are legal, valid and binding obligations of the
Company enforceable in accordance with their terms, except as limited or
affected by bankruptcy, insolvency, reorganization, receivership, moratorium or
other laws affecting enforcement of mortgagees' and other creditors' rights and
remedies generally [2 and are entitled to the benefit of the security afforded
by the Mortgage].

          3. An authorizing order has been issued by the Minnesota Public
Utilities Commission certifying the Company's capital structure and authorizing
the issuance and sale of the Securities, and to the best of our knowledge, said
order is still in full force and effect; and no further approval, authorization,
consent or order of any public board or body (other than in connection or in
compliance with the provisions of the securities or "blue sky" laws of any
jurisdiction) is legally required for the authorization of the issuance and sale
of the Securities.

          4. The Registration Statement and the Prospectus (except as to the
financial statements, statement of income and other financial or statistical
data contained therein, upon which we do not pass) comply as to form in all
material respects with the requirements of the Securities Act and the applicable
instructions, rules and regulations of the Securities and Exchange Commission
thereunder; the Registration Statement have each become, and at the date hereof
each of the Registration Statement is, effective under the Securities Act, and
to the best of our knowledge no proceedings for a stop order with respect
thereto are pending or threatened under Section 8 of the Securities Act.

          5. The [1 Mortgage] [2 Indenture] is duly qualified under the Trust
Indenture Act.

          6. The statements set forth in the Prospectus under the captions
[1 "Description of New Bonds" and "Certain Terms of the Offered Bonds."]
[2 "Description of the Debt Securities" and "Certain Terms of the Offered Debt
Securities"] constitute a summary of the securities, documents and instruments
therein described, are accurate and fairly present the information contained
therein in all material respects.

          7. The Agreement has been duly and validly authorized, executed and
delivered by the Company and is a valid and legally binding obligation of the
Company.

          8. The Company is not an "investment company", as such term is defined
in the Investment Company Act of 1940, as amended.

          In passing upon the forms of the Registration Statement and the
Prospectus, we necessarily assume the correctness and completeness of the
statements made or included therein by the Company and take no responsibility
therefor, except insofar as such statements relate to us and as set forth in the
Prospectus under the heading "Legal Opinions" and in paragraph 6 above. In the
course of the preparation by the Company of the Registration Statement and the
Prospectus, we have had conferences with certain of its officers and
representatives, with other counsel for the Company and with
PricewaterhouseCoopers LLP, the independent certified public accountants who
examined certain of the Company's financial statements incorporated by reference
in the Registration Statement. Our examination of the Registration Statement and
the Prospectus, and our discussions in the above-mentioned conferences did not
disclose to us any information which gives us reason to believe that, at the
Effective Date, the Registration Statement contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading or that the
Prospectus at the time it was filed electronically with the Commission pursuant
to Rule 424, and the Prospectus, as amended or supplemented at the date hereof,
contained or contains an untrue statement of a material fact or omitted or omits
to state a material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading. We do
not express any opinion or belief as to the financial statements, statement of
income or other financial or statistical data contained in the Registration
Statement or in the Prospectus.

          We are members of the New York Bar and do not hold ourselves out as
experts on the laws of Minnesota. As to all matters of Minnesota law (and as to
the incorporation of the Company, titles to property, franchises [1 and the lien
of the Mortgage], upon which we do not pass), we have relied with your consent
upon the opinion of even date herewith addressed to you by Philip R. Halverson,
Esq., Vice President, General Counsel and Secretary of the Company.

                                        Very truly yours,


                                        THELEN REID & PRIEST LLP

          I have reviewed all corporate proceedings taken by the Company in
respect of the authorization of the [1 Mortgage] [2 Indenture] and the issuance
and sale of the Securities thereunder.

          Upon the basis of my familiarity with these transactions and with the
Company's properties and affairs generally, I am of the opinion that:

          1. The [1 Mortgage] [2 Indenture] has been duly and validly authorized
by all necessary corporate action, has been validly executed and delivered, and
is a valid and binding mortgage of the Company enforceable in accordance with
its terms, except as limited or affected by bankruptcy, insolvency,
reorganization, receivership, moratorium or other laws affecting enforcement of
[1 mortgagees' and other] creditors' rights and remedies generally and general
principles of equity.

          2. The Securities are legal, valid and binding obligations of the
Company enforceable in accordance with their terms, except as limited or
affected by bankruptcy, insolvency, reorganization, receivership, moratorium or
other laws affecting enforcement of mortgagees' and other creditors' rights and
remedies generally and general principles of equity [1 and are entitled to the
benefit of the security afforded by the Mortgage].

          3. An authorizing order has been issued by the Minnesota Public
Utilities Commission certifying the Company's capital structure and authorizing
the issuance and sale of the Securities, and to the best of my knowledge, said
order is still in full force and effect; and no further approval, authorization,
consent or order of any public board or body (other than in connection or in
compliance with the provisions of the securities or "blue sky" laws of any
jurisdiction) is legally required for the authorization of the issuance and sale
of the Securities.

          4. The Registration Statement and the Prospectus (except as to the
financial statements, statement of income and other financial or statistical
data contained therein, upon which I do not pass) comply as to form in all
material respects with the requirements of the Securities Act and the applicable
instructions, rules and regulations of the Securities and Exchange Commission
thereunder; the Registration Statement have each become, and at the date hereof
each of the Registration Statement is, effective under the Securities Act and to
the best of my knowledge no proceedings for a stop order with respect thereto
are pending or threatened under Section 8 of the Securities Act.

          5. The [1 Mortgage] [2 Indenture] is duly qualified under the Trust
Indenture Act.

          6. The statements set forth in the Prospectus under the captions
[1 "Description of New Bonds" and "Certain Terms of the Offered Bonds."]
[2 "Description of the Debt Securities" and "Certain Terms of the Offered Debt
Securities"] constitute a summary of the securities, documents and instruments
therein described, are accurate and fairly present the information contained
therein in all material respects.

          7. The Agreement has been duly and validly authorized, executed and
delivered by the Company and is a valid and legally binding obligation of the
Company.


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

                                      A-2

          8. The Company is a validly organized and existing corporation under
the laws of the State of Minnesota and is duly qualified to do business, and is
doing business, in that State.

          9. The Company is a public utility corporation duly authorized by its
Articles of Incorporation to conduct the business which it is now conducting as
set forth in the Prospectus and the Company holds valid and subsisting
franchises, licenses and permits authorizing it to carry on the utility business
in which it is engaged.

          10. Each Material Subsidiary (as defined in the Agreement) of the
Company is a validly organized and existing corporation under the laws of the
State of its incorporation and is duly qualified to do business, and is doing
business, in such State and in each other State in which the failure to qualify
as a foreign corporation would be material to the Company and its subsidiaries,
taken as a whole.

          11. [1 The Company has good and sufficient title to all the properties
specifically described in the granting clauses of the Mortgage as owned by it,
subject only to excepted encumbrances as defined in the Mortgage and other
defects which the Company has the right to cure by condemnation proceedings if
the property is necessary for utility purposes, and which, in my opinion, do not
impair the use of such properties by the Company, except properties retired and
properties previously released from the lien of the Mortgage, and except that
the Company's practice is not to require examination of title, and I have not
examined title, to land upon which the Company has merely a transmission or
distribution line right of way or easement, reservoir lands, lands or rights
held for flowage, flooding or seepage purposes, riparian rights, or other
properties certified by the Company as costing $25,000 or less, titles to which
lands, rights or properties could, if necessary for utility purposes, be
perfected or obtained by condemnation proceedings. The description of all the
properties so specifically described in the Mortgage is adequate to constitute
the Mortgage a lien thereon, and said properties constitute all of the electric
generating plants and other materially important physical properties and
substantially all the other properties of the Company (other than those
expressly excepted). The Mortgage constitutes a valid, direct and first mortgage
lien upon the properties of the Company specifically described in the granting
clauses of the Mortgage or upon the interest of the Company therein and upon the
interest of the Company in all other properties described in the Mortgage and
intended to be subject to the lien thereof, subject only to excepted
encumbrances and defects as above stated, and will constitute a valid mortgage
lien upon all permanent physical properties and franchises (other than those
expressly excepted) acquired by the Company after the date of the [         ]
                                                                   ---------
Supplemental Indenture upon such acquisition, subject, however, to encumbrances
and liens, if any, existing or placed thereon at the date of acquisition thereof
by the Company, except that in the case of real estate or interests in real
estate the title to which is registered, the Mortgage becomes a lien thereon
upon the registration of said Mortgage against the appropriate certificates of
title.]

          12. Other than as stated in the Registration Statement and the
Prospectus there are no pending legal proceedings to which the Company or any
Material Subsidiary is a party or of which property of the Company or any
Material Subsidiary is the subject, which depart from the ordinary routine
litigation incident to the kind of business conducted by the Company or any such


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

Material Subsidiary, and which is material to the Company and its subsidiaries,
taken as a whole, and, to the best of my knowledge, no such proceedings are
known to be contemplated by governmental authorities.

          13. The portions of the answers to the items of the Registration
Statement and the portions of the information contained in the Prospectus, which
are stated therein to have been made on my authority as General Counsel of the
Company, have been reviewed by me and, as to matters of law and legal
conclusions, are correct.

          14. Neither the execution by the Company of the [1[          ]
                                                             ----------
Supplemental Indenture nor the issue and sale by the Company of the Bonds]
[2                                  nor the issue and sale by the Company of the
  ---------------------------------
Debt Securities] as contemplated by the Agreement nor the consummation by the
Company of the other transactions contemplated by the Agreement conflicts with,
or results in a breach of, the charter or by-laws of the Company or any Material
Subsidiary or any agreement or instrument known to me to which the Company or
any Material Subsidiary is a party or by which the Company or any Material
Subsidiary is bound, any law or regulation or, so far as is known to me, any
order or regulation of any court, governmental instrumentality or arbitrator,
and which conflict or breach is material to the Company and its subsidiaries,
taken as a whole.

          15. To the best of my knowledge, the Company is not currently in
breach of, or in default under, any material written agreement or instrument to
which it is a party or by which it or its property is bound or affected, and
which breach or default is material to the Company and its subsidiaries, taken
as a whole.

          In passing upon the forms of the Registration Statement and the
Prospectus, I necessarily assume the correctness and completeness of the
statements made or included therein by the Company and take no responsibility
therefor, except insofar as such statements relate to me and as set forth in the
Prospectus under the headings "Experts" and "Legal Opinions" and in paragraphs 6
and 13 above. In the course of the preparation by the Company of the
Registration Statement and the Prospectus, I had conferences with certain of its
officers and representatives, with other counsel for the Company and with
PricewaterhouseCoopers LLP, the independent certified public accountants who
examined certain of the Company's financial statements incorporated by reference
in the Registration Statement. My examination of the Registration Statement and
the Prospectus, and my discussions in the above-mentioned conferences did not
disclose to me any information which gives me reason to believe that, at the
Effective Date, the Registration Statement contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading or that the
Prospectus at the time it was filed electronically with the Commission pursuant
to Rule 424, and the Prospectus, as amended or supplemented at the date hereof,
contained or contains an untrue statement of a material fact or omitted or omits
to state a material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading. I do
not express any opinion or belief as to the financial statements, statement of
income or other financial or statistical data included in the Registration
Statement or in the Prospectus.

for in this Indenture relating to the proposed action (including any covenants

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

Company, unless such counsel knows, or in the exercise of reasonable care should

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

          Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted. Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Company which could not have been taken had the
original document or instrument not contained such error or omission, the action
so taken shall not be invalidated or otherwise rendered ineffective but shall be
and remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith. Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Company entitled to the benefits of this Indenture equally and ratably with all
other Outstanding Securities, except as aforesaid.

SECTION 104.   ACTS OF HOLDERS.

          (a) Any request, demand, authorization, direction, notice, consent,
     election, waiver or other action provided by this Indenture to be made,
     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 or, alternatively, may be embodied
     in and evidenced by the record of Holders voting in favor thereof, either
     in person or by proxies duly appointed in writing, at any meeting of
     Holders duly called and held in accordance with the provisions of Article
     Thirteen, or a combination of such instruments and any such record. Except
     as herein otherwise expressly provided, such action shall become effective
     when such instrument or instruments or record or both are delivered to the
     Trustee and, where it is hereby expressly required, to the Company. Such
     instrument or instruments and any such record (and the action embodied
     therein and evidenced thereby) are herein sometimes referred to as the

<PAGE>
                                       9


     "Act" of the Holders signing such instrument or instruments and so voting
     at any such meeting. Proof of execution of any such instrument or of a
     writing appointing any such agent, or of the holding by any Person of a
     Security, shall be sufficient for any purpose of this Indenture and
     (subject to Section 901) conclusive in favor of the Trustee and the
     Company, if made in the manner provided in this Section. The record of any
     meeting of Holders shall be proved in the manner provided in Section 1306.

          (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 or may be proved in any other manner which the Trustee
     and the Company deem sufficient. Where such execution is by a signer acting
     in a capacity other than his or her individual capacity, such certificate
     or affidavit shall also constitute sufficient proof of his or her
     authority.

          (c) The principal amount (except as otherwise contemplated in clause
     (y) of the first proviso to the definition of Outstanding) and serial
     numbers of Securities held by any Person, and the date of holding the same,
     shall be proved by the Security Register.

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

          (e) Until such time as written instruments shall have been delivered
     to the Trustee with respect to the requisite percentage of principal amount
     of Securities for the action contemplated by such instruments, any such
     instrument executed and delivered by or on behalf of a Holder may be
     revoked with respect to any or all of such Securities by written notice by
     such Holder or any subsequent Holder, proven in the manner in which such
     instrument was proven.

          (f) Securities of any series authenticated and delivered after any Act
     of Holders may, and shall if required by the Trustee, bear a notation in
     form approved by the Trustee as to any action taken by such Act of Holders.
     If the Company shall so determine, new Securities of any series so modified
     as to conform, in the opinion of the Trustee and the Company, to such
     action may be prepared and executed by the Company and authenticated and
     delivered by the Trustee in exchange for Outstanding Securities of such
     series.

          (g) If the Company shall solicit from Holders any request, demand,
     authorization, direction, notice, consent, waiver or other Act, the Company
     may, at its option, fix in advance a record date for the determination of
     Holders entitled to give such request, demand, authorization, direction,
     notice, consent, waiver or other Act, but the Company shall have no
     obligation to do so. If such a record date is fixed, such request, demand,

<PAGE>
                                       10


     authorization, direction, notice, consent, waiver or other Act may be given
     before or after such record date, but only the Holders of record at the
     close of business on the record date shall be deemed to be Holders for the
     purposes of determining whether Holders of the requisite proportion of the
     Outstanding Securities have authorized or agreed or consented to such
     request, demand, authorization, direction, notice, consent, waiver or other

SECTION 106.   NOTICE TO HOLDERS OF SECURITIES; WAIVER.

          Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently
given, and shall be deemed given, to Holders if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at the
address of such Holder as it appears in the Security Register, not later than
the latest date, if any, and not earlier than the earliest date, if any,
prescribed for the giving of such notice.

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

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

SECTION 107.   CONFLICT WITH TRUST INDENTURE ACT.

          If any provision of this Indenture limits, qualifies or conflicts with
another provision hereof which is required or deemed to be included in this
Indenture by, or is otherwise governed by, any of the provisions of the Trust
Indenture Act, such other provision shall control; and if any provision hereof
otherwise conflicts with the Trust Indenture Act, the Trust Indenture Act shall
control.

SECTION 108.   EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 109.   SUCCESSORS AND ASSIGNS.

          All covenants and agreements in this Indenture by the Company and
Trustee shall bind their respective successors and assigns, whether so expressed
or not.

SECTION 110.   SEPARABILITY CLAUSE.

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

SECTION 111.   BENEFITS OF INDENTURE.

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

SECTION 112.   GOVERNING LAW.

          This Indenture and the Securities shall be governed by and construed
in accordance with the internal laws of the State of New York, except to the
extent that the law of any other jurisdiction shall be mandatorily applicable.

SECTION 113.   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
other than a provision in Securities of any series, or in the Board Resolution
or Officer's Certificate which establishes the terms of the Securities of such
series, which specifically states that such provision shall apply in lieu of
this Section) 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, in each case with the same
force and effect, and in the same amount, as if made on the Interest Payment
Date or Redemption Date, or at the Stated Maturity, as the case may be, and, if
such payment is made or duly provided for on such Business Day, no interest
shall accrue on the amount so payable for the period from and after such
Interest Payment Date, Redemption Date or Stated Maturity, as the case may be,
to such Business Day.

     terms of such series, as provided in Sections 201 and 301;

          (b) a Company Order requesting the authentication and delivery of such

     indenture or Board Resolution, all as contemplated by Sections 201 and 301,
     either (i) establishing such terms or (ii) in the case of Securities of a
     series subject to a Periodic Offering, specifying procedures, acceptable to
     the Trustee, by which such terms are to be established (which procedures

          Trustee and issued and delivered by the Company in the manner and
          subject to any conditions specified in such Opinion of Counsel, will
          have been duly issued under this Indenture and will constitute valid
          and legally binding obligations of the Company, entitled to the
          benefits provided by this Indenture, and enforceable in accordance
          with their terms, except as the same may be limited by laws relating
          to or affecting generally the enforcement of creditors' rights,
          including, without limitation, bankruptcy and insolvency laws and to
          general principles of equity (regardless of whether such
          enforceability is considered in a proceeding in equity or at law);

          provided, however, that, with respect to Securities of a series
          subject to a Periodic Offering, the Trustee shall be entitled to
          receive such Opinion of Counsel only once at or prior to the time of
          the first authentication and delivery of such Securities (provided

          of all Securities of such series) and that, in lieu of the opinions
          described in clauses (ii) and (iii) above, Counsel may opine that:

                    been established pursuant to a Company Order or Orders or
                    pursuant to such procedures acceptable to the Trustee as may
                    be specified from time to time by a Company Order or Orders,
                    all as contemplated by and in accordance with the instrument
                    or instruments delivered pursuant to clause (a) above, such
                    terms will have been duly authorized by the Company and will
                    have been established in conformity with the provisions of
                    this Indenture; and

                              (y) such Securities, when authenticated and
                    delivered by the Trustee in accordance with this Indenture
                    and the Company Order or Orders or specified procedures

                    by the Company in the manner and subject to any conditions
                    specified in such Opinion of Counsel, will have been duly
                    issued under this Indenture and will constitute valid and
                    legally binding obligations of the Company, entitled to the
                    benefits provided by the Indenture, and enforceable in
                    accordance with their terms, except as the same may be
                    limited by laws relating to or affecting generally the
                    enforcement of creditors' rights, including, without
                    limitation, bankruptcy and insolvency laws, and to general
                    principles of equity (regardless of whether such
                    enforceability is considered in a proceeding in equity or at
                    law).

          With respect to Securities of a series subject to a Periodic Offering,
the Trustee may conclusively rely, as to the authorization by the Company of any
of such Securities, the form and terms thereof and the legality, validity,
binding effect and enforceability thereof, and compliance of the authentication
and delivery thereof with the terms and conditions of this Indenture, upon the
Opinion of Counsel and other documents delivered pursuant to Sections 201 and
301 and this Section, as applicable, at or prior to the time of the first
authentication of Securities of such series unless and until such opinion or
other documents have been superseded or revoked or expire by their terms. In
connection with the authentication and delivery of Securities of a series
subject to a Periodic Offering, the Trustee shall be entitled to assume that the
Company's instructions to authenticate and deliver such Securities do not
violate any applicable law or any applicable rule, regulation or order of any
Governmental Authority having jurisdiction over the Company.

          If the form or terms of the Securities of any series have been
established by or pursuant to a Board Resolution or an Officer's Certificate as
permitted by Sections 201 or 301, the Trustee shall not be required to
authenticate such Securities if the issuance of such Securities pursuant to this
Indenture will materially or 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.

          Unless otherwise specified as contemplated by Section 301 with respect
to any series of Securities, each Security shall be dated the date of its
authentication.

          Unless otherwise specified as contemplated by Section 301 with respect
to any series of Securities, 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

<PAGE>
                                       20


for herein executed by the Trustee or an Authenticating Agent by manual
signature of an authorized signatory thereof, 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 to the Company, or any Person
acting on its behalf, but shall never have been issued and sold by the Company,
and the Company shall deliver such Security to the Security Registrar for
cancellation as provided in Section 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Officer's
Certificate or an Opinion of Counsel) stating that such Security has never been
issued and sold by the Company, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits hereof.

SECTION 304.   TEMPORARY SECURITIES.

          Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, 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; provided, however, that temporary
Securities need not recite specific redemption, sinking fund, conversion or
exchange provisions.

          Unless otherwise specified as contemplated by Section 301 with respect
to the Securities of any series, after the preparation of definitive Securities
of such series, the temporary Securities of such series shall be exchangeable,
without charge to the Holder thereof, for definitive Securities of such series
upon surrender of such temporary Securities at the office or agency of the
Company maintained pursuant to Section 602 in a Place of Payment for such
Securities. Upon such surrender of temporary Securities for such exchange, the
Company shall, except as aforesaid, execute and the Trustee shall authenticate
and deliver in exchange therefor definitive Securities of the same series, of
authorized denominations and of like tenor and aggregate principal amount.

          Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder.

SECTION 305.   REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

          The Company shall cause to be kept in each office designated pursuant
to Section 602, with respect to the Securities of each series, a register (all
registers kept in accordance with this Section being 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 of
such series and the registration of transfer thereof. The Company shall
designate one Person to maintain the Security Register for the Securities of
each series on a consolidated basis, and such Person is referred to herein, with
respect to such series, as the "Security Registrar." Anything herein to the

<PAGE>
                                       21


contrary notwithstanding, the Company may designate one or more of its offices
as an office in which a register with respect to the Securities of one or more
series shall be maintained, and the Company may designate itself the Security
Registrar with respect to one or more of such series. The Security Register
shall be open for inspection by the Trustee and the Company at all reasonable
times.

          Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, upon surrender for registration of
transfer of any Security of such series at the office or agency of the Company
maintained pursuant to Section 602 in a Place of Payment for such 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 authorized denominations and of like tenor and aggregate
principal amount.

          Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, any Security of such series may be
exchanged at the option of the Holder, for one or more new Securities of the
same series, of authorized denominations and of like tenor and aggregate
principal amount, upon surrender of the Securities to be exchanged at any 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 delivered upon any registration of transfer or exchange
of Securities shall be 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, the Trustee or the
Security Registrar) be duly endorsed or shall be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Trustee or the
Security Registrar, as the case may be, duly executed by the Holder thereof or
his attorney duly authorized in writing.

          Unless otherwise specified as contemplated by Section 301 with respect
to Securities of any series, no service charge shall be made for any
registration of transfer or exchange of Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 406 or 1206 not
involving any transfer.

          The Company shall not be required to execute or to provide for the
registration of transfer of or the exchange of (a) Securities of any series
during a period of 15 days immediately preceding the date of the mailing of any
notice of redemption of such Securities called for redemption or (b) any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

<PAGE>
                                       22


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

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

          If there shall be delivered to the Company and the Trustee (a)
evidence to their satisfaction of the ownership of and the destruction, loss or
theft of any Security and (b) such security or indemnity as may be reasonably
required by them to save each of them and any agent of either of them harmless,
then, in the absence of notice to the Company or the Trustee that such Security
is held by a Person purporting to be the owner of such Security, the Company
shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of the same series, and
of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

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

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
reasonable 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 other than
the Holder of such new Security, and any such new Security shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Securities of such series duly issued hereunder.

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

SECTION 307.   PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

          Unless otherwise specified as contemplated by Section 301 with respect
to the Securities of any series, interest on any Security which is payable, and
is punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

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

<PAGE>
                                       23


such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (a) or (b) below:

          (a) 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 date (herein called a "Special Record Date") for the payment of such
     Defaulted Interest, which shall be fixed in the following manner. The
     Company shall notify the Trustee in writing of the amount of Defaulted
     Interest proposed to be paid on each Security of such series and the date
     of the proposed payment, and at the same time the Company shall deposit
     with the Trustee an amount of money equal to the aggregate amount proposed
     to be paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit on or prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     clause provided. Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days after the receipt by the Trustee of the notice of the
     proposed payment. The Trustee shall promptly notify the Company of such
     Special Record Date and, in the name and at the expense of the Company,
     shall promptly 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 the address
     of such Holder 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.

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

SECTION 308.   PERSONS DEEMED OWNERS.

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the absolute owner of
such Security for the purpose of receiving payment of principal of and premium,
if any, and (subject to Sections 305 and 307) interest, if any, on such Security

<PAGE>
                                       24


and for all other purposes whatsoever, whether or not such Security be overdue,
and neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

SECTION 309.   CANCELLATION BY SECURITY REGISTRAR.

          All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Security
Registrar, be delivered to the Security Registrar and, if not theretofore
canceled, shall be promptly canceled by the Security Registrar. The Company may
at any time deliver to the Security Registrar for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever or which the Company shall not have issued and
sold, and all Securities so delivered shall be promptly canceled by the Security
Registrar. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Securities held by the Security
Registrar shall be disposed of in accordance with a Company Order delivered to
the Security Registrar and the Trustee, and the Security Registrar shall
promptly deliver a certificate of disposition to the Trustee and the Company
unless, by a Company Order, similarly delivered, the Company shall direct that
canceled Securities be returned to it. The Security Registrar shall promptly
deliver evidence of any cancellation of a Security in accordance with this
Section 309 to the Trustee and the Company.

SECTION 310.   COMPUTATION OF INTEREST.

          Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year consisting of twelve 30-day months and
for any period shorter than a full month, on the basis of the actual number of
days elapsed in such period.

SECTION 311.   PAYMENT TO BE IN PROPER CURRENCY.

          In the case of the Securities of any series denominated in any
currency other than Dollars or in a composite currency (the "Required
Currency"), except as otherwise specified with respect to such Securities as
contemplated by Section 301, the obligation of the Company to make any payment
of the principal thereof, or the premium, if any, or interest, if any, thereon,
shall not be discharged or satisfied by any tender by the Company, or recovery
by the Trustee, in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the Trustee timely holding
the full amount of the Required Currency then due and payable. If any such
tender or recovery is in a currency other than the Required Currency, the
Trustee may take such actions as it considers appropriate to exchange such
currency for the Required Currency. The costs and risks of any such exchange,
including without limitation the risks of delay and exchange rate fluctuation,
shall be borne by the Company, the Company shall remain fully liable for any
shortfall or delinquency in the full amount of Required Currency then due and
payable, and in no circumstances shall the Trustee be liable therefor except in
the case of its negligence or willful misconduct.

                                  ARTICLE FOUR

                            REDEMPTION OF SECURITIES

SECTION 401.   APPLICABILITY OF ARTICLE.

          Securities of any series which are redeemable before their Stated
Maturity (or, if the principal of the Securities of any series is payable in
installments, the Stated Maturity of the final installment of the principal
thereof) shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of such
series) in accordance with this Article.

SECTION 402.   ELECTION TO REDEEM; NOTICE TO TRUSTEE.

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or an Officer's Certificate. The Company shall,
at least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of such Securities
to be redeemed. In the case of any redemption of Securities (a) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture or (b) pursuant to an election of the
Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officer's Certificate
evidencing compliance with such restriction or condition.

SECTION 403.   SELECTION OF SECURITIES TO BE REDEEMED.

          If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected by the Trustee from the
Outstanding Securities of such series not previously called for redemption, by
such method as shall be provided for any particular series, or, in the absence
of any such provision, 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 such series or
any integral multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of such series; provided, however, that if, as indicated in an
Officer's Certificate, the Company shall have offered to purchase all or any
principal amount of the Securities then Outstanding of any series, and less than
all of such Securities as to which such offer was made shall have been tendered
to the Company for such purchase, the Trustee, if so directed by Company Order,
shall select for redemption all or any principal amount of such Securities which
have not been so tendered.

          The Trustee shall promptly notify the Company and the Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected to be redeemed in part, 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.

<PAGE>
                                       26


SECTION 404.   NOTICE OF REDEMPTION.

          Notice of redemption shall be given in the manner provided in Section
106 to the Holders of the Securities to be redeemed not less than 30 nor more
than 60 days prior to the Redemption Date.

          All notices of redemption shall state:

          (a) the Redemption Date,

          (b) the Redemption Price, or the formula pursuant to which the
     Redemption Price is to be determined if the Redemption Price cannot be
     determined at the time the notice is given,

          (c) if less than all the Securities of any series are to be redeemed,
     the identification of the particular Securities to be redeemed and the
     portion of the principal amount of any Security to be redeemed in part and,
     in the case of any such Security of such series to be redeemed in part,
     that, on and after the Redemption Date, upon surrender of such Security, a
     new Security or Securities of such series in principal amount equal to the
     remaining unpaid principal amount thereof will be issued as provided in
     Section 406,

          (d) that on the Redemption Date the Redemption Price, together with
     accrued interest, if any, to the Redemption Date, 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,

          (e) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price and accrued interest, if any, unless it
     shall have been specified as contemplated by Section 301 with respect to
     such Securities that such surrender shall not be required,

          (f) that the redemption is for a sinking or other fund, if such is the
     case,

          (g) the CUSIP numbers, if any, assigned to such Securities; provided
     however, that such notice may state that no representation is made as to
     the correctness of CUSIP numbers, and the redemption of such Securities
     shall not be affected by any defect in or omission of such number, and

          (h) such other matters as the Company shall deem desirable or
     appropriate.

          Unless otherwise specified with respect to any Securities in
accordance with Section 301, with respect to any notice of redemption of
Securities at the election of the Company, unless, upon the giving of such
notice, such Securities shall be deemed to have been paid in accordance with
Section 701, such notice may state that such redemption shall be conditional
upon the receipt by the Paying Agent or Agents for such Securities, on or prior
to the date fixed for such redemption, of money sufficient to pay the principal
of and premium, if any, and interest, if any, on such Securities and that if
such money shall not have been so received such notice shall be of no force or
effect and the Company shall not be required to redeem such Securities. In the

<PAGE>
                                       27


event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Paying Agent or Agents for the Securities
otherwise to have been redeemed shall promptly return to the Holders thereof any
of such Securities which had been surrendered for payment upon such redemption.

          Notice of redemption of Securities to be redeemed at the election of
the Company, and any notice of non-satisfaction of a condition for redemption as
aforesaid, shall be given by the Company or, at the Company's request, by the
Security Registrar in the name and at the expense of the Company. Notice of
mandatory redemption of Securities shall be given by the Security Registrar in
the name and at the expense of the Company.

SECTION 405.   SECURITIES PAYABLE ON REDEMPTION DATE.

          Notice of redemption having been given as aforesaid, and the
conditions, if any, set forth in such notice having been satisfied, the
Securities or portions thereof 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, in the case of an unconditional notice of redemption,
the Company shall default in the payment of the Redemption Price and accrued
interest, if any) such Securities or portions thereof, if interest-bearing,
shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with such notice, such Security or portion thereof shall be paid
by the Company at the Redemption Price, together with accrued interest, if any,
to the Redemption Date; provided, however, that no such surrender shall be a
condition to such payment if so specified as contemplated by Section 301 with
respect to such Security; and provided, further, that except as otherwise
specified as contemplated by Section 301 with respect to such Security, any
installment of interest on any Security the Stated Maturity of which installment
is on or prior to the Redemption Date shall be payable to the Holder of such
Security, or one or more Predecessor Securities, registered as such at the close
of business on the related Regular Record Date according to the terms of such
Security and subject to the provisions of Section 307.

SECTION 406.   SECURITIES REDEEMED IN PART.

          Upon the surrender of any Security which is to be redeemed only in
part 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), the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security, without
service charge, a new Security or Securities of the same series, of any
authorized denomination requested by such Holder and of like tenor and in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered.

                                       28


                                  ARTICLE FIVE

                                  SINKING FUNDS

SECTION 501.   APPLICABILITY OF ARTICLE.

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

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of 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 502. Each sinking fund payment shall be applied to the
redemption of Securities of the series in respect of which it was made as
provided for by the terms of such Securities.

SECTION 502.   SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

          The Company (a) may deliver to the Trustee Outstanding Securities
(other than any previously called for redemption) of a series in respect of
which a mandatory sinking fund payment is to be made and (b) may apply as a
credit Securities of such series which have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities or Outstanding Securities purchased by the Company, in each case
in satisfaction of all or any part of such mandatory sinking fund payment with
respect to the Securities of such series; provided, however, that no Securities
shall be applied in satisfaction of a mandatory sinking fund payment if such
Securities shall have been previously so applied. Securities so applied 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 mandatory sinking fund payment shall be reduced
accordingly.

SECTION 503.   REDEMPTION OF SECURITIES FOR SINKING FUND.

          Not less than 45 days prior to each sinking fund payment date for the
Securities of any series, the Company shall deliver to the Trustee an Officer's
Certificate specifying:

          (a) the amount of the next succeeding mandatory sinking fund payment
     for such series;

          (b) the amount, if any, of the optional sinking fund payment to be
     made together with such mandatory sinking fund payment;

          (c) the aggregate sinking fund payment;

<PAGE>
                                       29


          (d) the portion, if any, of such aggregate sinking fund payment which
     is to be satisfied by the payment of cash; and

          The Company shall pay the principal of and premium, if any, and
interest, if any, on the Securities of each series in accordance with the terms
of such Securities and this Indenture.

SECTION 602.   MAINTENANCE OF OFFICE OR AGENCY.

          The Company shall maintain in each Place of Payment for the Securities
of each series an office or agency where payment of such Securities shall be
made, where the registration of transfer or exchange of such Securities may be
effected and where notices and demands to or upon the Company in respect of such
Securities and this Indenture may be served. The Company shall give prompt
written notice to the Trustee of the location, and any change in the location,

any series, or shall fail to furnish the Trustee with the address thereof,

thereof may be effected and notices and demands in respect thereof may be served
at the Corporate Trust Office of the Trustee, and the Company hereby appoints

          The Company may also from time to time designate one or more other
offices or agencies with respect to the Securities of one or more series, for
any or all of the foregoing purposes and may from time to time rescind such
designations; provided, however, that, unless otherwise specified as
contemplated by Section 301 with respect to the Securities of such series, no
such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency for such purposes in each Place of
Payment for such Securities in accordance with the requirements set forth above.

<PAGE>
                                       30

to the Holders in the manner specified in Section 106, of any such designation
or rescission and of any change in the location of any such other office or
agency.

          Anything herein to the contrary notwithstanding, any office or agency
required by this Section may be maintained at an office of the Company, in which
event the Company shall perform all functions to be performed at such office or
agency.

SECTION 603.   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 the Securities of any series, it shall, on or before each due date of
the principal of and premium, if any, and interest, if any, on any of such
Securities, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal and premium or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided. The Company shall promptly notify the Trustee of any
failure by the Company (or any other obligor on such Securities) to make any
payment of principal of or premium, if any, or interest, if any, on such
Securities.

          Whenever the Company shall have one or more Paying Agents for the
Securities of any series, it shall, on or before each due date of the principal
of and premium, if any, and interest, if any, on such Securities, deposit with
such Paying Agents sums sufficient (without duplication) to pay the principal
and premium 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 shall promptly notify the
Trustee of any failure by it so to act.

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

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

          (b) give the Trustee notice of any failure by the Company (or any
     other obligor upon such Securities) to make any payment of principal of or
     premium, if any, or interest, if any, on such Securities; and

          (c) 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 and furnish to the Trustee such
     information as it possesses regarding the names and addresses of the
     Persons entitled to such sums.

<PAGE>
                                       31


          The Company may at any time pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent, such sums to be held by the Trustee upon the same trusts as those
upon which such sums were held by the Company or such Paying Agent and, if so
stated in a Company Order delivered to the Trustee, in accordance with the
provisions of Article Seven; 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, if any, on any Security 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, or, if then held by the
Company, shall be discharged from such trust; and, upon such payment or
discharge, the Holder of such Security shall, as an unsecured general creditor
and not as a Holder of an Outstanding Security, look only to the Company for
payment of the amount so due and payable and remaining unpaid, 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 payment to the Company, may at the expense of the Company cause to be
mailed, on one occasion only, notice to such Holder that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such mailing, any unclaimed balance of such money then
remaining will be paid to the Company.

common with others, make reasonable effort to cause) to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as,

in connection therewith may be properly conducted; provided, however, that

term, provision or condition set forth in (a) Section 602 or any additional
covenant or restriction specified with respect to the Securities of any series,
as contemplated by Section 301, if before the time for such compliance the
Holders of at least a majority in aggregate principal amount of the Outstanding
Securities of all series with respect to which compliance with Section 602 or
such additional covenant or restriction is to be omitted, considered as one
class, shall, by Act of such Holders, either waive such compliance in such

compliance the Holders of at least a majority in principal amount of Securities
Outstanding under this Indenture shall, by Act of such Holders, either waive

provision or condition; but, in the case of (a) or (b), 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.

          expressly understood that such Secured Obligations (x) may, but need
          not, bear interest, (y) may, but need not, contain provisions for the

     by making advances or incurring an obligation, give value to enable the
     grantor of such Lien to acquire rights in or the use of such property;

     Persons described in clause (a) or (b) above, provided that such Lien may

     purposes; or

          (4) otherwise constitutes a purchase money mortgage or a purchase
     money security interest under applicable law;

                           SATISFACTION AND DISCHARGE

SECTION 701.   DEFEASANCE.

          Any Security or Securities, or any portion of the principal amount
thereof, shall be deemed to have been paid for all purposes of this Indenture,
and the entire indebtedness of the Company in respect thereof shall be deemed to
have been satisfied and discharged, if there shall have been irrevocably
deposited with the Trustee or any Paying Agent (other than the Company), in
trust:

          (a) money in an amount which shall be sufficient, or

          (b) in the case of a deposit made prior to the Maturity of such
     Securities or portions thereof, Government Obligations, which shall not
     contain provisions permitting the redemption or other prepayment thereof at
     the option of the issuer thereof, the principal of and the interest on
     which when due, without any regard to reinvestment thereof, will provide
     moneys which, together with the money, if any, deposited with or held by
     the Trustee or such Paying Agent, shall be sufficient, or

          (c) a combination of (a) or (b) which shall be sufficient,

to pay when due the principal of and premium, if any, and interest, if any, due
and to become due on such Securities or portions thereof on or prior to
Maturity; provided, however, that in the case of the provision for payment or
redemption of less than all the Securities of any series, such Securities or
portions thereof shall have been selected by the Trustee as provided herein and,
in the case of a redemption, the notice requisite to the validity of such
redemption shall have been given or irrevocable authority shall have been given
by the Company to the Trustee to give such notice, under arrangements
satisfactory to the Trustee; and provided, further, that the Company shall have
delivered to the Trustee and such Paying Agent:

               (x) if such deposit shall have been made prior to the Maturity of
          such Securities, a Company Order stating that the money and Government
          Obligations deposited in accordance with this Section shall be held in
          trust, as provided in Section 703; and

               (y) if Government Obligations shall have been deposited, an
          Opinion of Counsel that the obligations so deposited constitute
          Government Obligations and do not contain provisions permitting the
          redemption or other prepayment at the option of the issuer thereof,
          and an opinion of an independent public accountant of nationally
          recognized standing, selected by the Company, to the effect that the
          requirements set forth in clause (b) above have been satisfied; and

               (z) if such deposit shall have been made prior to the Maturity of
          such Securities, an Officer's Certificate stating the Company's
          intention that, upon delivery of such Officer's Certificate, its

<PAGE>
                                       42


          indebtedness in respect of such Securities or portions thereof will
          have been satisfied and discharged as contemplated in this Section.

          Upon the deposit of money or Government Obligations, or both, in
accordance with this Section, together with the documents required by clauses
(x), (y) and (z) above, the Trustee shall, upon receipt of a Company Request,
acknowledge in writing that the Security or Securities or portions thereof with
respect to which such deposit was made are deemed to have been paid for all
purposes of this Indenture and that the entire indebtedness of the Company in
respect thereof has been satisfied and discharged as contemplated in this
Section. In the event that all of the conditions set forth in the preceding
paragraph shall have been satisfied in respect of any Securities or portions
thereof except that, for any reason, the Officer's Certificate specified in
clause (z) shall not have been delivered, such Securities or portions thereof
shall nevertheless be deemed to have been paid for all purposes of this
Indenture, and the Holders of such Securities or portions thereof shall
nevertheless be no longer entitled to the benefits of this Indenture or of any
of the covenants of the Company under Article Six (except the covenants
contained in Sections 602 and 603) or any other covenants made in respect of
such Securities or portions thereof as contemplated by Section 301, but the
indebtedness of the Company in respect of such Securities or portions thereof
shall not be deemed to have been satisfied and discharged prior to Maturity for
any other purpose, and the Holders of such Securities or portions thereof shall
continue to be entitled to look to the Company for payment of the indebtedness
represented thereby; and, upon Company Request, the Trustee shall acknowledge in
writing that such Securities or portions thereof are deemed to have been paid
for all purposes of this Indenture.

          If payment at Stated Maturity of less than all of the Securities of
any series is to be provided for in the manner and with the effect provided in
this Section, the Security Registrar shall select such Securities, or portions
of principal amount thereof, in the manner specified by Section 403 for
selection for redemption of less than all the Securities of a series.

          In the event that Securities which shall be deemed to have been paid
for purposes of this Indenture, and, if such is the case, in respect of which
the Company's indebtedness shall have been satisfied and discharged, all as
provided in this Section do not mature and are not to be redeemed within the 60
day period commencing with the date of the deposit of moneys or Government
Obligations, as aforesaid, the Company shall, as promptly as practicable, give a
notice, in the same manner as a notice of redemption with respect to such
Securities, to the Holders of such Securities to the effect that such deposit
has been made and the effect thereof.

          Notwithstanding that any Securities shall be deemed to have been paid
for purposes of this Indenture, as aforesaid, the obligations of the Company and
the Trustee in respect of such Securities under Sections 304, 305, 306, 404, 503
(as to notice of redemption), 602, 603, 907 and 915 and this Article Seven shall
survive.

          The Company shall pay, and shall indemnify the Trustee or any Paying
Agent with which Government Obligations shall have been deposited as provided in
this Section against, any tax, fee or other charge imposed on or assessed
against such Government Obligations or the principal or interest received in
respect of such Government Obligations, including, but not limited to, any such
tax payable by any entity deemed, for tax purposes, to have been created as a
result of such deposit.

<PAGE>
                                       43


          Anything herein to the contrary notwithstanding, (a) if, at any time
after a Security would be deemed to have been paid for purposes of this
Indenture, and, if such is the case, the Company's indebtedness in respect
thereof would be deemed to have been satisfied or discharged, pursuant to this
Section (without regard to the provisions of this paragraph), the Trustee or any
Paying Agent, as the case may be, shall be required to return the money or
Government Obligations, or combination thereof, deposited with it as aforesaid
to the Company or its representative under any applicable Federal or State
bankruptcy, insolvency or other similar law, such Security shall thereupon be
deemed retroactively not to have been paid and any satisfaction and discharge of
the Company's indebtedness in respect thereof shall retroactively be deemed not
to have been effected, and such Security shall be deemed to remain Outstanding
and (b) any satisfaction and discharge of the Company's indebtedness in respect
of any Security shall be subject to the provisions of the last paragraph of
Section 603.

SECTION 702.   SATISFACTION AND DISCHARGE OF INDENTURE.

          This Indenture shall upon Company Request cease to be of further
effect (except as hereinafter expressly provided), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

          (a) no Securities remain Outstanding hereunder; and

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

provided, however, that if, in accordance with the last paragraph of Section
701, any Security, previously deemed to have been paid for purposes of this
Indenture, shall be deemed retroactively not to have been so paid, this
Indenture shall thereupon be deemed retroactively not to have been satisfied and
discharged, as aforesaid, and to remain in full force and effect, and the
Company shall execute and deliver such instruments as the Trustee shall
reasonably request to evidence and acknowledge the same.

          Notwithstanding the satisfaction and discharge of this Indenture as
aforesaid, the obligations of the Company and the Trustee under Sections 304,
305, 306, 404, 503 (as to notice of redemption), 602, 603, 907 and 915 and this
Article Seven shall survive.

          Upon satisfaction and discharge of this Indenture as provided in this
Section, the Trustee shall assign, transfer and turn over to the Company,
subject to the lien provided by Section 907, any and all money, securities and
other property then held by the Trustee for the benefit of the Holders of the
Securities other than money and Government Obligations held by the Trustee
pursuant to Section 703 and shall execute and deliver to the Company such
instruments as, in the judgment of the Company, shall be necessary, desirable or
appropriate to effect or evidence the satisfaction and discharge of this
Indenture.

SECTION 703.   APPLICATION OF TRUST MONEY.

          Neither the Government Obligations nor the money deposited pursuant to
Section 701, nor the principal or interest payments on any such Government
Obligations, shall be withdrawn or used for any purpose other than, and shall be
held in trust for, the payment of the principal of and premium, if any, and

<PAGE>
                                       44


interest, if any, on the Securities or portions of principal amount thereof in
respect of which such deposit was made, all subject, however, to the provisions
of Section 603; provided, however, that, so long as there shall not have
occurred and be continuing an Event of Default any cash received from such
principal or interest payments on such Government Obligations, if not then
needed for such purpose, shall, to the extent practicable, be invested in
Government Obligations of the type described in clause (b) in the first
paragraph of Section 701 maturing at such times and in such amounts as shall be
sufficient to pay when due the principal of and premium, if any, and interest,
if any, due and to become due on such Securities or portions thereof on and
prior to the Maturity thereof, and interest earned from such reinvestment shall
be paid over to the Company as received, free and clear of any trust, lien or
pledge under this Indenture except the lien provided by Section 907; and
provided, further, that, so long as there shall not have occurred and be
continuing an Event of Default, any moneys held in accordance with this Section
on the Maturity of all such Securities in excess of the amount required to pay
the principal of and premium, if any, and interest, if any, then due on such
Securities shall be paid over to the Company free and clear of any trust, lien
or pledge under this Indenture except the lien provided by Section 907; and
provided, further, that if an Event of Default shall have occurred and be
continuing, moneys to be paid over to the Company pursuant to this Section shall
be held until such Event of Default shall have been waived or cured.

applicable to all Outstanding Securities or an Event of Default specified in
Section 801(d) or (e) shall have occurred and be continuing, either the Trustee
or the Holders of not less than 33% in principal amount of all Securities then
Outstanding (considered as one class), and not the Holders of the Securities of
any one of such series, may declare the principal amount (or, if any of the
Securities are Discount Securities, such portion of the principal amount as may

<PAGE>
                                       46


be specified in the terms thereof as contemplated by Section 301) of all
Outstanding Securities and interest accrued thereon to be due and payable
immediately. As a consequence of each such declaration (herein referred to as a
declaration of acceleration) with respect to Securities of any series, the
principal amount (or specified portion thereof in the case of Discount
Securities) of such Securities and interest accrued thereon shall become due and
payable immediately.

          At any time after such a declaration of acceleration with respect to
Securities of any series shall have been made and before a judgment or decree
for payment of the money due shall have been obtained by the Trustee as
hereinafter in this Article provided, the Event or Events of Default giving rise
to such declaration of acceleration shall, without further act, be deemed to
have been waived, and such declaration and its consequences shall, without
further act, be deemed to have been rescinded and annulled, if

          (a) the Company shall have paid or deposited with the Trustee a sum
     sufficient to pay

               (1) all overdue interest, if any, on all Securities of such
          series;

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

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

               (4) all amounts due to the Trustee under Section 907; and

          (b) any other Event or Events of Default with respect to Securities of
     such series, other than the nonpayment of the principal of Securities of
     such series which shall have become due solely by such declaration of
     acceleration, shall have been cured or waived as provided in Section 813.

          No such rescission shall affect any subsequent Event of Default or
impair any right consequent thereon.

SECTION 803.   COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

          If an Event of Default described in clause (a) or (b) of Section 801
shall have occurred and be continuing, the Company shall, upon demand of the
Trustee, pay to it, for the benefit of the Holders of the Securities of the
series with respect to which such Event of Default shall have occurred, the
whole amount then due and payable on such Securities for principal and premium,
if any, and interest, if any, and, to the extent permitted by law, interest on
premium, if any, and on any overdue principal and interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover any amounts due to the Trustee under
Section 907. Unless otherwise specified pursuant to Section 301 with respect to
any series of Securities, the rate or rates at which Securities shall bear

<PAGE>
                                       47


interest on overdue principal, premium, if any, and interest, if any, shall be,
to the extent permitted by law, the same rate or rates at which such Securities
shall bear interest prior to Maturity.

          If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, 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.

          If an Event of Default with respect to Securities of any series shall
have occurred and be 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 804.   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,

          (a) to file and prove a claim for the whole amount of principal,
     premium, if any, and interest, if any, 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 amounts due to the Trustee under Section 907) and of the Holders
     allowed in such judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amounts due it under Section 907.

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

                                       48


SECTION 805.   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 in respect of which such judgment has been
recovered.

SECTION 806.   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, if any, upon presentation of the Securities in respect of
which or for the benefit of which such money shall have been collected 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
     907;

          SECOND: To the payment of the amounts then due and unpaid upon the
     Securities for principal of and premium, if any, and interest, if any, 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, premium, if any,
     and interest, if any, respectively; and

          THIRD: To the payment of the remainder, if any, to the Company or to
     whomsoever may be lawfully entitled to receive the same or as a court of
     competent jurisdiction may direct.

SECTION 807.   LIMITATION ON SUITS.

          No Holder 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:

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

          (b) the Holders of not less than a majority in aggregate principal
     amount of the Outstanding Securities of such series in respect of which an
     Event of Default shall have occurred and be continuing 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;

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

<PAGE>
                                       49


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

          (e) no direction inconsistent with such written request shall have
     been given to the Trustee during such 60-day period by the Holders of a
     majority in aggregate principal amount of the Outstanding Securities of all
     series in respect of which an Event of Default shall have occurred and be
     continuing, considered as one class;

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

SECTION 808.   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
307) interest, if any, 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 809.   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 shall have been
discontinued or abandoned for any reason, or shall have 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, and Trustee and such
Holder shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and such Holder
shall continue as though no such proceeding had been instituted.

SECTION 810.   RIGHTS AND REMEDIES CUMULATIVE.

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

SECTION 811.   DELAY OR OMISSION NOT WAIVER.

          No delay or omission of the Trustee or of any Holder 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

<PAGE>
                                       50


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 812.   CONTROL BY HOLDERS OF SECURITIES.

          If an Event of Default shall have occurred and be continuing in
respect of a series of Securities, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of such 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, however,
that if an Event of Default shall have occurred and be continuing with respect
to more than one series of Securities, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all such series, considered as
one class, shall have the right to make such direction, and not the Holders of
the Securities of any one of such series; and provided, further, that such
direction shall not be in conflict with any rule of law or with this Indenture.
The Trustee may take any other action, deemed proper by the Trustee, which is
not inconsistent with any such direction. Before proceeding to exercise any
right or power hereunder at the direction of such Holders, the Trustee shall be
entitled to receive from such Holders reasonable security or indemnity against
the costs, expenses and liabilities which might be incurred by it in compliance
with any such direction.

SECTION 813.   WAIVER OF PAST DEFAULTS.

          The Holders of not less than a majority in aggregate 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

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

          (b) in respect of a covenant or provision hereof which under Section
     1202 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 and
all Events 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 814.   UNDERTAKING FOR COSTS.

          The Company and the Trustee agree, and each Holder 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,

<PAGE>
                                       51


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; all in the
manner, to the extent and except as otherwise provided in the Trust Indenture
Act; 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
aggregate principal amount of the Outstanding Securities of all series in
respect of which such suit may be brought, considered as one class, or to any
suit instituted by any Holder for the enforcement of the payment of the
principal of or premium, if any, or interest, if any, 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 815.   WAIVER OF 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 stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  ARTICLE NINE

                                   THE TRUSTEE

SECTION 901.   CERTAIN DUTIES AND RESPONSIBILITIES.

          (a) The Trustee shall have and be subject to all the duties and
     responsibilities specified with respect to an indenture trustee in the
     Trust Indenture Act and no implied covenants or obligations shall be read
     into this Indenture against the Trustee. For purposes of Sections 315(a)
     and 315(c) of the Trust Indenture Act, the term "default" is hereby defined
     as an Event of Default which has occurred and is continuing.

          (b) 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.

          (c) Notwithstanding anything contained in this Indenture to the
     contrary, the duties and responsibilities of the Trustee under this
     Indenture shall be subject to the protections, exculpations and limitations
     on liability afforded to an indenture trustee under the provisions of the
     Trust Indenture Act. For the purposes of Sections 315(b)(2) and 315(d)(2)
     of the Trust Indenture Act, the term "responsible officer" is hereby
     defined as a Responsible Officer and the chairman or vice chairman of the
     board of directors, the chairman or vice chairman of the executive
     committee of the board of directors, the president, any vice president, any
     assistant vice president, the secretary, any assistant secretary, the
     treasurer, any assistant treasurer, the cashier, any assistant cashier, any

<PAGE>
                                       52


     trust officer or assistant trust officer, the controller and any assistant
     controller of the Trustee, or any other officer of the Trustee customarily
     performing functions similar to those performed by a Responsible Officer or
     any of the above designated officers and also means, with respect to a
     particular corporate trust matter, any other officer to whom such matter is
     referred because of his or her knowledge of and familiarity with the
     particular subject.

          (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 902.   NOTICE OF DEFAULTS.

          The Trustee shall give notice of any default hereunder with respect to
the Securities of any series to the Holders of Securities of such series in the
manner and to the extent required to do so by the Trust Indenture Act, unless
such default shall have been cured or waived; provided, however, that in the
case of any default of the character specified in Section 801(c), no such notice
to Holders shall be given until at least 45 days after the occurrence thereof.
For the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time, or both, would become, an Event of Default.

SECTION 903.   CERTAIN RIGHTS OF TRUSTEE.

          Subject to the provisions of Section 901 and to the applicable
provisions of the Trust Indenture Act:

          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting in good faith 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 reasonably 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, or as
     otherwise expressly provided herein, and any resolution of the Board of
     Directors 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 Officer's 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;

<PAGE>
                                       53


          (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 Holder pursuant to this Indenture, unless such Holder shall have
     offered to the Trustee reasonable security or indemnity against the costs,
     expenses and liabilities which might be incurred by it in compliance with
     such request or direction;

          (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 (subject to applicable legal requirements) be entitled to examine,
     during normal business hours, the books, records and premises of the
     Company, personally or by agent or attorney;

          (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;

          (h) the Trustee shall not be charged with knowledge of any default or
     Event of Default, as the case may be, with respect to the Securities of any
     series for which it is acting as Trustee unless either (1) a Responsible
     Officer of the Trustee shall have actual knowledge of the default or Event
     of Default, as the case may be, or (2) written notice of such default or
     Event of Default, as the case may be, shall have been given to the Trustee
     by the Company, any other obligor on such Securities or by any Holder of
     such Securities; and

          (i) the rights, privileges, protections, immunities and benefits given
     to the Trustee, including, without limitation, its right to be indemnified,
     are extended to, and shall be enforceable by, the Trustee in each of its
     capacities hereunder.

SECTION 904.   NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

          The recitals contained herein and in the Securities (except the
Trustee's certificates of authentication) shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 905.   MAY HOLD SECURITIES.

          Each of the Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 908 and 913, may otherwise deal with the Company with the same rights
it would have if it were not the Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.

<PAGE>
                                       54


SECTION 906.   MONEY HELD IN TRUST.

          Money held by the Trustee in trust hereunder need not be segregated
from other funds, except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
expressly provided herein or otherwise agreed with, and for the sole benefit of,
the Company.

SECTION 907.   COMPENSATION AND REIMBURSEMENT.

          The Company shall

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

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

          (c) indemnify the Trustee for, and hold it harmless from and against,
     any loss, liability or expense reasonably incurred by it arising out of or
     in connection with the acceptance or administration of the trust or trusts
     hereunder or the performance of its duties hereunder, including the
     reasonable costs and expenses of defending itself against any claim or
     liability in connection with the exercise or performance of any of its
     powers or duties hereunder, except to the extent any such loss, liability
     or expense may be attributable to its negligence, wilful misconduct, bad
     faith or breach of its obligations under this Indenture.

          As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such other than
property and funds held in trust under Section 703 (except as otherwise provided
in Section 703). "Trustee" for purposes of this Section shall include any
predecessor Trustee; provided, however, that the negligence, wilful misconduct
or bad faith of any Trustee hereunder shall not affect the rights of any other
Trustee hereunder.

          In addition to the rights provided to the Trustee pursuant to the
provisions of the immediately preceding paragraph of this Section 907, when the
Trustee incurs expenses or renders services in connection with an Event of
Default specified in Section 801(d) or Section 801(e), the expenses (including
the reasonable charges and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
applicable Federal or State bankruptcy, insolvency or other similar law.

          The provisions of this Section 907 shall survive the termination of

SECTION 908.   DISQUALIFICATION; CONFLICTING INTERESTS.

          If the Trustee shall have or acquire any conflicting interest within
the meaning of the Trust Indenture Act, it shall either eliminate such
conflicting interest or resign to the extent, in the manner and with the effect,
and subject to the conditions, provided in the Trust Indenture Act and this
Indenture. For purposes of Section 310(b)(1) of the Trust Indenture Act and to
the extent permitted thereby, the Trustee, in its capacity as trustee in respect
of the Securities of any series, shall not be deemed to have a conflicting
interest arising from its capacity as trustee in respect of the Securities of
any other series.

SECTION 909.   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

          There shall at all times be a Trustee hereunder which shall be

          (a) a corporation organized and doing business under the laws of the
     United States, any State or Territory 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, or

          (b) if and to the extent permitted by the Commission by rule,
     regulation or order upon application, a corporation or other Person
     organized and doing business under the laws of a foreign government,
     authorized under such laws to exercise corporate trust powers, having a
     combined capital and surplus of at least $50,000,000 or the Dollar
     equivalent of the applicable foreign currency and subject to supervision or
     examination by authority of such foreign government or a political
     subdivision thereof substantially equivalent to supervision or examination
     applicable to United States institutional trustees,

and, in either case, qualified and eligible under this Article and the Trust
Indenture Act. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of such supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. 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 910.   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 911.

          (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 911
     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.

<PAGE>
                                       56


          (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 908 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 909 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

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

then, in any such case, (x) the Company by a Board Resolution may remove the
Trustee with respect to all Securities or (y) subject to Section 814, any Holder
who has been a bona fide Holder 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
     (other than as contemplated in clause (y) in subsection (d) of this
     Section), 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 911. 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 911,
     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 911, any Holder who
     has been a bona fide Holder of a Security of such series for at least six
     months may, on behalf of itself 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.

<PAGE>
                                       57


          (f) So long as no event which is, or after notice or lapse of time, or
     both, would become, an Event of Default shall have occurred and be
     continuing, and except with respect to a Trustee appointed by Act of the
     Holders of a majority in principal amount of the Outstanding Securities
     pursuant to subsection (e) of this Section, if the Company shall have
     delivered to the Trustee (i) a Board Resolution appointing a successor
     Trustee, effective as of a date specified therein, and (ii) an instrument
     of acceptance of such appointment, effective as of such date, by such
     successor Trustee in accordance with Section 911, the Trustee shall be
     deemed to have resigned as contemplated in subsection (b) of this Section,
     the successor Trustee shall be deemed to have been appointed by the Company
     pursuant to subsection (e) of this Section and such appointment shall be
     deemed to have been accepted as contemplated in Section 911, all as of such
     date, and all other provisions of this Section and Section 911 shall be
     applicable to such resignation, appointment and acceptance except to the
     extent inconsistent with this subsection (f).

          (g) 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 911.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

          (a) In case of the appointment hereunder of a successor Trustee with
     respect to the Securities of all series, every such successor Trustee so
     appointed shall execute, acknowledge and deliver to the Company and to the
     retiring Trustee an instrument accepting such appointment, and thereupon
     the resignation or removal of the retiring Trustee shall become effective
     and such successor Trustee, without any further act, deed or conveyance,
     shall become vested with all the rights, powers, trusts and duties of the
     retiring Trustee; but, on the request of the Company or the successor
     Trustee, such retiring Trustee shall, upon payment of all sums owed to it,
     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 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

<PAGE>
                                       58


     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, upon payment of all sums owed to it, 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 instruments which fully vest in and confirm to such successor
     Trustee all such rights, powers and trusts referred to in subsection (a) or
     (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 912.   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

          Any Person into which the Trustee may be merged or converted or with
which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any Person
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 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 913.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

          If the Trustee shall be or become a creditor of the Company or any
other obligor upon the Securities (other than by reason of a relationship
described in Section 311(b) of the Trust Indenture Act), the Trustee shall be
subject to any and all applicable provisions of the Trust Indenture Act
regarding the collection of claims against the Company or such other obligor.
For purposes of Section 311(b) of the Trust Indenture Act:

     orders drawn upon banks or bankers and payable upon demand;

          (b) the term "self-liquidating paper" means any draft, bill of
     exchange, acceptance or obligation which is made, drawn, negotiated or
     incurred by the Company for the purpose of financing the purchase,
     processing, manufacturing, shipment, storage or sale of goods, wares 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.

SECTION 914.   CO-TRUSTEES AND SEPARATE TRUSTEES.

          At any time or times, for the purpose of meeting the legal
requirements of any applicable jurisdiction, the Company and the Trustee shall
have power to appoint, and, upon the written request of the Trustee or of the
Holders of at least 33% in principal amount of the Securities then Outstanding,
the Company shall for such purpose join with the Trustee in the execution and
delivery of all instruments and agreements necessary or proper to appoint, one
or more Persons approved by the Trustee either to act as co-trustee, jointly
with the Trustee, or to act as separate trustee, in either case with such powers
as may be provided in the instrument of appointment, and to vest in such Person
or Persons, in the capacity aforesaid, any property, title, right or power
deemed necessary or desirable, subject to the other provisions of this Section.
If the Company does not join in such appointment within 15 days after the
receipt by it of a request so to do, or if an Event of Default shall have
occurred and be continuing, the Trustee alone shall have power to make such
appointment.

          Should any written instrument or instruments from the Company be
required by any co-trustee or separate trustee so appointed to more fully
confirm to such co-trustee or separate trustee such property, title, right or
power, any and all such instruments shall, on request, be executed, acknowledged
and delivered by the Company.

          Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following conditions:

          (a) the Securities shall be authenticated and delivered, and all
     rights, powers, duties and obligations hereunder in respect of the custody
     of securities, cash and other personal property held by, or required to be
     deposited or pledged with, the Trustee hereunder, shall be exercised
     solely, by the Trustee;

          (b) the rights, powers, duties and obligations hereby conferred or
     imposed upon the Trustee in respect of any property covered by such
     appointment shall be conferred or imposed upon and exercised or performed
     either by the Trustee or by the Trustee and such co-trustee or separate
     trustee jointly, as shall be provided in the instrument appointing such
     co-trustee or separate trustee, except to the extent that under any law of
     any jurisdiction in which any particular act is to be performed, the
     Trustee shall be incompetent or unqualified to perform such act, in which

<PAGE>
                                       60


     event such rights, powers, duties and obligations shall be exercised and
     performed by such co-trustee or separate trustee;

          (c) the Trustee at any time, by an instrument in writing executed by
     it, with the concurrence of the Company, may accept the resignation of or
     remove any co-trustee or separate trustee appointed under this Section,
     and, if an Event of Default shall have occurred and be continuing, the
     Trustee shall have power to accept the resignation of, or remove, any such
     co-trustee or separate trustee without the concurrence of the Company. Upon
     the written request of the Trustee, the Company shall join with the Trustee
     in the execution and delivery of all instruments and agreements necessary
     or proper to effectuate such resignation or removal. A successor to any
     co-trustee or separate trustee so resigned or removed may be appointed in
     the manner provided in this Section;

          (d) no co-trustee or separate trustee hereunder shall be personally
     liable by reason of any act or omission of the Trustee, or any other such
     trustee hereunder; and

          (e) any Act of Holders delivered to the Trustee shall be deemed to
     have been delivered to each such co-trustee and separate trustee.

SECTION 915.   APPOINTMENT OF AUTHENTICATING AGENT.

          The Trustee may appoint an Authenticating Agent or Agents with respect
to the Securities of one or more series, which shall be authorized to act on
behalf of the Trustee to authenticate Securities of such series issued upon
original issuance and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 306, and Securities so authenticated
shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Indenture to the authentication and delivery
of Securities by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States, any State or territory 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

<PAGE>
                                       61


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 to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company. Upon receiving such a notice of
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 may appoint a successor Authenticating
Agent which shall be acceptable to the Company. Any successor Authenticating
Agent upon acceptance of its appointment hereunder shall become vested with all
the rights, powers and duties of its predecessor hereunder, 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.

          The provisions of Sections 308, 904 and 905 shall be applicable to
each Authenticating Agent.

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

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


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

                                             Authorized Signatory

          If all of the Securities of a series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested by the Company in writing (which writing
need not comply with Section 102 and need not be accompanied by an Opinion of

<PAGE>
                                       62


Counsel), shall appoint, in accordance with this Section and in accordance with
such procedures as shall be acceptable to the Trustee, an Authenticating Agent
having an office in a Place of Payment designated by the Company with respect to
such series of Securities.

          Upon any consolidation by the Company with or merger by the Company
into any other Person conveyance, or other transfer or lease of the properties
and assets of the Company substantially as an entirety in accordance with
Section 1101, the successor Person by such consolidation or into which the
Company is merged or the Person to which such conveyance, transfer or lease is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein, and thereafter, except in
the case of a lease, the predecessor Person shall be relieved of all obligations
and covenants under this Indenture and the Securities Outstanding hereunder.

                                 ARTICLE TWELVE

                             SUPPLEMENTAL INDENTURES

SECTION 1201.  SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.

          (d) to change or eliminate any provision of this Indenture or to add
     any new provision to this Indenture; provided, however, that if such
     change, elimination or addition shall adversely affect the interests of the
     Holders of Securities of any series (other than any series the terms of
     which permit such change, elimination or addition) Outstanding on the date
     of such indenture supplemental hereto in any material respect, such change,
     elimination or addition shall become effective with respect to such series
     only pursuant to the provisions of Section 1202 hereof or when no Security
     of such series remains Outstanding; or

          (e) to provide collateral security for all or part of the Securities;

     of the vote or consent of, the holders thereof, and for any and all other
     matters incidental thereto; or

          (h) to evidence and provide for the acceptance of appointment
     hereunder by a separate or successor Trustee with respect to the Securities
     of one or more series and to add to or change any of the provisions of this
     Indenture as shall be necessary to provide for or facilitate the
     administration of the trusts hereunder by more than one Trustee, pursuant
     to the requirements of Section 911(b); or

          (i) to provide for the procedures required to permit the Company to
     utilize, at its option, a noncertificated system of registration for all,
     or any series of, the Securities; or

          (j) to change any place or places where (1) the principal of and

     shall be payable, (2) all or any series of Securities may be surrendered
     for registration of transfer, (3) all or any series of Securities may be
     surrendered for exchange and (4) notices and demands to or upon the Company
     in respect of all or any series of Securities and this Indenture may be

          (k) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision

     Indenture, provided that such other changes or additions shall not
     adversely affect the interests of the Holders of Securities of any series
     in any material respect.

          Without limiting the generality of the foregoing, if the Trust
Indenture Act as in effect at the date of the execution and delivery of this
Indenture or at any time thereafter shall be amended and

               (x) if any such amendment shall require one or more changes to
          any provisions hereof or the inclusion herein of any additional
          provisions, or shall by operation of law be deemed to effect such

<PAGE>
                                       65


          changes or incorporate such provisions by reference or otherwise, this
          Indenture shall be deemed to have been amended so as to conform to
          such amendment to the Trust Indenture Act, and the Company and the
          Trustee may, without the consent of any Holders, enter into an
          indenture supplemental hereto to effect or evidence such changes or
          additional provisions; or

               (y) if any such amendment shall permit one or more changes to, or
          the elimination of, any provisions hereof which, at the date of the
          execution and delivery hereof or at any time thereafter, are required
          by the Trust Indenture Act to be contained herein, this Indenture
          shall be deemed to have been amended to effect such changes or
          elimination, and the Company and the Trustee may, without the consent
          of any Holders, enter into an indenture supplemental hereto to
          evidence such amendment hereof.

SECTION 1202.  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

          With the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of all series then Outstanding
under this Indenture, considered as one class, by Act of said Holders delivered
to the Company and the Trustee, the Company, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture or modifying
in any manner the rights of the Holders of Securities of such series under the
Indenture; provided, however, that if there shall be Securities of more than one
series Outstanding hereunder and if a proposed supplemental indenture shall
directly affect the rights of the Holders of Securities of one or more, but less
than all, of such series, then the consent only of the Holders of a majority in
aggregate principal amount of the Outstanding Securities of all series so
directly affected, considered as one class, shall be required; and provided,
further, that no such supplemental indenture shall:

          (a) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon (or the amount of any
     installment of interest thereon) or change the method of calculating such
     rate or reduce any premium payable upon the redemption thereof, or reduce
     the amount of the principal of a Discount Security that would be due and
     payable upon a declaration of acceleration of the Maturity thereof pursuant
     to Section 802, or change the coin or currency (or other property), in
     which any Security or any premium or the interest thereon is payable, or
     impair the right to institute suit for the enforcement of any such payment
     on or after the Stated Maturity of any Security (or, in the case of
     redemption, on or after the Redemption Date), without, in any such case,
     the consent of the Holder of such Security, or

          (b) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of the Holders of which is required
     for any such supplemental indenture, or the consent of the Holders of which
     is required for any waiver of compliance with any provision of this
     Indenture or of any default hereunder and its consequences, or reduce the
     requirements of Section 1304 for quorum or voting, without, in any such

<PAGE>
                                       66


     case, the consent of the Holders of each Outstanding Security of such
     series, or

          (c) modify any of the provisions of this Section, Section 607 or
     Section 813 with respect to the Securities of any series, except to
     increase the percentages in principal amount referred to in this Section or
     such other Sections or to provide that other provisions of this Indenture
     cannot be modified or waived without the consent of the Holder of each
     Outstanding Security affected thereby; provided, however, that this clause
     shall not be deemed to require the consent of any Holder with respect to
     changes in the references to "the Trustee" and concomitant changes in this
     Section, or the deletion of this proviso, in accordance with the
     requirements of Sections 911(b) and 1201(h).

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

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof. A waiver by a
Holder of such Holder's right to consent under this Section shall be deemed to
be a consent of such Holder.

SECTION 1203.  EXECUTION OF SUPPLEMENTAL INDENTURES.

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 901) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties, immunities or liabilities under this Indenture or
otherwise.

SECTION 1204.  EFFECT OF SUPPLEMENTAL INDENTURES.

          Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby. Any supplemental indenture permitted by this Article may
restate this Indenture in its entirety, and, upon the execution and delivery
thereof, any such restatement shall supersede this Indenture as theretofore in
effect for all purposes.

SECTION 1205.  CONFORMITY WITH TRUST INDENTURE ACT.

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

<PAGE>
                                       67


SECTION 1206.  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

          Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

SECTION 1207.  MODIFICATION WITHOUT SUPPLEMENTAL INDENTURE.

          If the terms of any particular series of Securities shall have been
established in a Board Resolution or an Officer's Certificate as contemplated by
Section 301, and not in an indenture supplemental hereto, additions to, changes
in or the elimination of any of such terms may be effected by means of a
supplemental Board Resolution or Officer's Certificate, as the case may be,
delivered to, and accepted by, the Trustee; provided, however, that such
supplemental Board Resolution or Officer's Certificate shall not be accepted by
the Trustee or otherwise be effective unless all conditions set forth in this
Indenture which would be required to be satisfied if such additions, changes or
elimination were contained in a supplemental indenture shall have been
appropriately satisfied. Upon the acceptance thereof by the Trustee, any such
supplemental Board Resolution or Officer's Certificate shall be deemed to be a
"supplemental indenture" for purposes of Section 1204 and 1206.

                                ARTICLE THIRTEEN

                   MEETINGS OF HOLDERS; ACTION WITHOUT MEETING

SECTION 1301.  PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

          A meeting of Holders of Securities of one or more, or all, series may
be called at any time and from time to time pursuant to this Article to make,
give or take any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be made, given or taken by
Holders of Securities of such series.

SECTION 1302.  CALL, NOTICE AND PLACE OF MEETINGS.

          (a) The Trustee may at any time call a meeting of Holders of
     Securities of one or more, or all, series for any purpose specified in
     Section 1301, to be held at such time and at such place in the Borough of
     Manhattan, The City of New York, as the Trustee shall determine, or, with
     the approval of the Company, at any other place. Notice of every such
     meeting, setting forth the time and the place of such meeting and in
     general terms the action proposed to be taken at such meeting, shall be
     given, in the manner provided in Section 106, not less than 21 nor more
     than 180 days prior to the date fixed for the meeting.

          (b) If the Trustee shall have been requested to call a meeting of the
     Holders of Securities of one or more, or all, series by the Company or by
     the Holders of 33% in aggregate principal amount of all of such series,

<PAGE>
                                       68


     considered as one class, for any purpose specified in Section 1301, by
     written request setting forth in reasonable detail the action proposed to
     be taken at the meeting, and the Trustee shall not have given the notice of
     such meeting within 21 days after receipt of such request or shall not
     thereafter proceed to cause the meeting to be held as provided herein, then
     the Company or the Holders of Securities of such series in the amount above
     specified, as the case may be, may determine the time and the place in the
     Borough of Manhattan, The City of New York, or in such other place as shall
     be determined or approved by the Company, for such meeting and may call
     such meeting for such purposes by giving notice thereof as provided in
     subsection (a) of this Section.

          (c) Any meeting of Holders of Securities of one or more, or all,
     series shall be valid without notice if the Holders of all Outstanding
     Securities of such series are present in person or by proxy and if
     representatives of the Company and the Trustee are present, or if notice is
     waived in writing before or after the meeting by the Holders of all
     Outstanding Securities of such series, or by such of them as are not
     present at the meeting in person or by proxy, and by the Company and the
     Trustee.

SECTION 1303.  PERSONS ENTITLED TO VOTE AT MEETINGS.

          To be entitled to vote at any meeting of Holders of Securities of one
or more, or all, series a Person shall be (a) a Holder of one or more

instrument in writing as proxy for a Holder or Holders of one or more
Outstanding Securities of such series by such Holder or Holders. The only
Persons who shall be entitled to attend any meeting of Holders of Securities of
any series shall be the Persons entitled to vote at such meeting and their
counsel, any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

SECTION 1304.  QUORUM; ACTION.

          The Persons entitled to vote a majority in aggregate principal amount
of the Outstanding Securities of the series with respect to which a meeting
shall have been called as hereinbefore provided, considered as one class, shall
constitute a quorum for a meeting of Holders of Securities of such series;
provided, however, that if any action is to be taken at such meeting which this
Indenture expressly provides may be taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of such series, considered as one class, the Persons
entitled to vote such specified percentage in principal amount of the
Outstanding Securities of such series, considered as one class, shall constitute
a quorum. In the absence of a quorum within one hour of the time appointed for
any such meeting, the meeting shall, if convened at the request of Holders of
Securities of such series, be dissolved. In any other case the meeting may be
adjourned for such period as may be determined by the chairman of the meeting
prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for such
period as may be determined by the chairman of the meeting prior to the
adjournment of such adjourned meeting. Except as provided by Section 1305(e),
notice of the reconvening of any meeting adjourned for more than 30 days shall
be given as provided in Section 1302(a) not less than 10 days prior to the date

<PAGE>
                                       69


on which the meeting is scheduled to be reconvened. Notice of the reconvening of
an adjourned meeting shall state expressly the percentage, as provided above, of
the principal amount of the Outstanding Securities of such series which shall
constitute a quorum.

          Except as limited by Section 1202, any resolution presented to a
meeting or adjourned meeting duly reconvened at which a quorum is present as
aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in aggregate principal amount of the Outstanding Securities of the
series with respect to which such meeting shall have been called, considered as
one class; provided, however, that, except as so limited, any resolution with
respect to any action which this Indenture expressly provides may be taken by
the Holders of a specified percentage, which is less than a majority, in
principal amount of the Outstanding Securities of such series, considered as one
class, may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders
of such specified percentage in principal amount of the Outstanding Securities
of such series, considered as one class.

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

SECTION 1305.  ATTENDANCE AT MEETINGS; DETERMINATION OF VOTING RIGHTS;
               CONDUCT AND ADJOURNMENT OF MEETINGS.

          (a) Attendance at meetings of Holders of Securities may be in person
     or by proxy; and, to the extent permitted by law, any such proxy shall
     remain in effect and be binding upon any future Holder of the Securities
     with respect to which it was given unless and until specifically revoked by
     the Holder or future Holder of such Securities before being voted.

          (b) Notwithstanding any other provisions of this Indenture, the
     Trustee may make such reasonable regulations as it may deem advisable for
     any meeting of Holders of Securities in regard to proof of the holding of
     such Securities and of the appointment of proxies and in regard to the
     appointment and duties of inspectors of votes, the submission and
     examination of proxies, certificates and other evidence of the right to
     vote, and such other matters concerning the conduct of the meeting as it
     shall deem appropriate. Except as otherwise permitted or required by any
     such regulations, the holding of Securities shall be proved in the manner
     specified in Section 104 and the appointment of any proxy shall be proved
     in the manner specified in Section 104. Such regulations may provide that
     written instruments appointing proxies, regular on their face, may be
     presumed valid and genuine without the proof specified in Section 104 or
     other proof.

          (c) The Trustee shall, by an instrument in writing, appoint a
     temporary chairman of the meeting, unless the meeting shall have been
     called by the Company or by Holders as provided in Section 1302(b), in
     which case the Company or the Holders of Securities of the series calling
     the meeting, as the case may be, shall in like manner appoint a temporary
     chairman. A permanent chairman and a permanent secretary of the meeting

<PAGE>
                                       70


     shall be elected by vote of the Persons entitled to vote a majority in
     aggregate principal amount of the Outstanding Securities of all series
     represented at the meeting, considered as one class.

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

          (e) Any meeting duly called pursuant to Section 1302 at which a quorum
     is present may be adjourned from time to time by Persons entitled to vote a
     majority in aggregate principal amount of the Outstanding Securities of all
     series represented at the meeting, considered as one class; and the meeting
     may be held as so adjourned without further notice.

SECTION 1306.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

          The vote upon any resolution submitted to any meeting of Holders shall
be by written ballots on which shall be subscribed the signatures of the Holders
or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities, of the series with respect to which the
meeting shall have been called, held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports of all
votes cast at the meeting. A record of the proceedings of each meeting of
Holders shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1302 and, if
applicable, Section 1304. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

SECTION 1307.  ACTION WITHOUT MEETING.

          In lieu of a vote of Holders at a meeting as hereinbefore contemplated
in this Article, any request, demand, authorization, direction, notice, consent,
waiver or other action may be made, given or taken by Holders by written
instruments as provided in Section 104.

         IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

SECTION 1401.  LIABILITY SOLELY CORPORATE.

          No recourse shall be had for the payment of the principal of or
premium, if any, or interest, if any, on any Securities, or any part thereof, or
for any claim based thereon or otherwise in respect thereof, or of the
indebtedness represented thereby, or upon any obligation, covenant or agreement
under this Indenture, against any incorporator, stockholder, officer or
director, as such, past, present or future of the Company or of any predecessor
or successor corporation (either directly or through the Company or a
predecessor or successor corporation), whether by virtue of any constitutional
provision, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly agreed and understood that this
Indenture and all the Securities are solely corporate obligations, and that no
personal liability whatsoever shall attach to, or be incurred by, any
incorporator, stockholder, officer or director, past, present or future, of the
Company or of any predecessor or successor corporation, either directly or
indirectly through the Company or any predecessor or successor corporation,
because of the indebtedness hereby authorized or under or by reason of any of
the obligations, covenants or agreements contained in this Indenture or in any
of the Securities or to be implied herefrom or therefrom, and that any such
personal liability is hereby expressly waived and released as a condition of,
and as part of the consideration for, the execution of this Indenture and the
issuance of the Securities.

provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company

Trustee shall not have received from the Holders of a majority in aggregate
principal amount of Securities of all series at the time Outstanding in respect
of which an Event of Default shall have occurred and be continuing a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder of
this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

(1)     The supplemental ratio of earnings to fixed charges includes Minnesota
        Power's obligation under a contract with Square Butte Electric
        Cooperative which extends through 2027, pursuant to which Minnesota
        Power is entitled to approximately 71% of the output of a 455-megawatt
        coal-fired generating unit. Minnesota Power is obligated to pay its pro
        rata share of Square Butte's costs based on output entitlement from the
        unit. Minnesota Power's payment obligation is suspended if Square Butte
        fails to deliver any power, whether produced or purchased, for a period
        of one year. Square Butte's fixed costs consist primarily of debt
        service. Variable operating costs include the price of coal purchased
        from BNI Coal, Ltd., under a long-term contract.
