                             BLACK HILLS CORPORATION

GENERAL

       On December 22, 2000, we completed the formation of a holding company
that allows us to pursue, through separate subsidiaries, business
opportunities in markets that are both regulated and unregulated. The
securities offered by this prospectus are securities of the new holding
company, Black Hills Corporation.

OUR BUSINESS

       We are a diversified energy company operating in the United States
with three major business groups - electric utility, independent energy and
communications.

         ELECTRIC UTILITY

       Our electric utility group, which operates through Black Hills Power,
Inc., is engaged in the generation, purchase, transmission and sale of
electricity to approximately 58,000 customers, of which approximately 90% are
located in South Dakota, with the remainder located in Wyoming and Montana.
We meet the needs of our customers for electric power through our owned
generating capacity of coal-, oil- and natural gas-fired generating units
providing 393 megawatts of power, and through contract purchases.

       INDEPENDENT ENERGY

       Our independent energy group consists of three units:

       -      fuel production;

       -      fuel marketing and transportation; and

       -      independent power production.

       FUEL PRODUCTION. As of December 31, 1999, we had 277 million tons of
low-sulfur, sub-bituminous coal reserves at our Wyodak mine located near
Gillette, Wyoming that provides coal directly to three on-site electric
generation facilities. Our oil and gas exploration and production unit
operates approximately 298 oil and gas wells, all in Wyoming, and owns
working interests in another 309 wells located in California, Montana, North
Dakota, Texas, Wyoming, Louisiana and Oklahoma and operated by others. As of
December 31, 1999, we had reserves of 4.1 million barrels of oil and 19.5
billion cubic feet of natural gas, with approximately 60% of our current
production consisting of natural gas.

       FUEL MARKETING AND TRANSPORTATION. Our fuel marketing and
transportation unit offers wholesale natural gas, crude oil and coal
marketing and risk management products and services to customers in the East
Coast, Midwest, Southwest, Rocky Mountain, West Coast and Northwest regions
of the United States. Our customers include natural gas distribution
companies, municipalities, industrial users, oil and gas producers, electric
utilities and coal mines. Our average daily marketing volumes for the 12
months ended September 30, 2000 were 676,000 million British thermal units of
natural gas, 33,400 barrels of oil and 4,700 tons of coal.

                                       -4-

<PAGE>

       INDEPENDENT POWER PRODUCTION. Our independent power unit acquires,
develops and operates unregulated power plants. In July 2000, we expanded our
presence in the independent power business by completing the acquisition of
Indeck Capital, Inc. The acquisition and subsequent additions provide us with
varying interests in 15 operating independent gas-fired and hydroelectric
power plants in California, New York, Massachusetts, Colorado and Idaho with
a total net ownership interest of approximately 245 megawatts, and minority
interests in power-related funds with investments in over 35 power projects
throughout the United States and in various foreign countries. We have an
additional net ownership interest of approximately 230 megawatts of
generation capacity in various stages of development and construction.

       COMMUNICATIONS

       Our majority-owned communications unit, known as Black Hills FiberCom,
offers a full suite of local and long distance telephone service, expanded
cable television service, cable modem Internet access and high-speed data and
video services to residential and business customers.

OUR EXECUTIVE OFFICES

       We are incorporated in South Dakota and our headquarters and principal
executive offices are located at 625 Ninth Street, P.O. Box 1400, Rapid City,
South Dakota 57709.

               RATIOS OF EARNINGS TO FIXED CHARGES AND EARNINGS TO
                   FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

The following table sets forth our ratios of earnings to fixed charges and
earnings to fixed charges and preferred stock dividends. The ratios were
computed by dividing earnings by either fixed charges or combined fixed
charges and preferred stock dividends. For this purpose, earnings include
income before income taxes, fixed charges and distributed income of equity
investees (excluding capitalized interest and a minority interest in pre-tax
income of subsidiaries that have not incurred fixed charges). Fixed charges
include interest expense, amortization of debt expense and interest
capitalized during the period.

                      DESCRIPTION OF SENIOR DEBT SECURITIES

GENERAL

       The following description applies to the senior debt securities
offered by this prospectus. The senior debt securities will be direct,
unsecured obligations of Black Hills and will rank on a parity with all of
our outstanding unsecured senior indebtedness. The senior debt securities may
be issued in one or more series. The senior debt securities will be issued
under an indenture between us and the trustee specified in the applicable
prospectus supplement.

       The statements under this caption are brief summaries of certain
provisions contained in the indenture, do not claim to be complete and are
qualified in their entirety by reference to the indenture, a copy of which is
filed as an exhibit to the registration statement of which this prospectus
forms a part. Whenever defined terms are used but not defined in this
prospectus, those terms have the meanings given to them in the indenture.

       The following material describes certain general terms and provisions
of the senior debt securities to which any prospectus supplement may relate.
The particular terms of any senior debt security and the extent, if any, to
which these general provisions may apply to such senior debt securities will
be described in the prospectus supplement relating to the senior debt
securities.

       The indenture does not limit the aggregate principal amount of senior
debt securities which may be issued under it. Rather, the indenture provides
that senior debt securities of any series may be issued under it up to the
aggregate principal amount which we may authorize from time to time. Senior
debt securities may be denominated in any currency or currency unit we
designate. Neither the indenture nor the senior debt securities will limit or
otherwise restrict the amount of other debt which we may incur or the other
securities which we may issue.

       Senior debt securities of a series may be issuable in registered form
without coupons ("Registered Securities") or in the form of one or more
global securities in registered form (each a "Global Security").

       You must review the prospectus supplement for a description of the

            securities will be payable;

       -    the interest rate or rates, which may be fixed or variable, for

            option or (2) mandatorily pursuant to any sinking, purchase or
            similar fund or (3) at the option of the holder, and the
            redemption or repayment price or prices;

       -    the terms, if any, upon which the senior debt securities may be
            convertible into or exchanged for any other kind of our securities
            or indebtedness or of any other issuer or obligor and the terms
            and conditions upon which the conversion or exchange would be

       -    any other terms of the senior debt securities not inconsistent
            with the provisions of the indenture.

                                       -8-

<PAGE>

       If any of the senior debt securities are sold for one or more foreign
currencies or foreign currency units or if the principal of or any premium or
interest on any series of senior debt securities is payable in one or more
foreign currencies or foreign currency units, the restrictions, elections,
tax consequences, specific terms and other information with respect to that
issue of senior debt securities and those currencies or currency units will
be described in the applicable prospectus supplement.

       A judgment for money damages by courts in the United States, including
a money judgment based on an obligation expressed in a foreign currency, will
ordinarily be rendered only in U.S. dollars. New York statutory law provides
that a court shall render a judgment or decree in the foreign currency of the
underlying obligation and that the judgment or decree shall be converted into
U.S. dollars at the exchange rate prevailing on the date of entry of the
judgment or decree.

       Senior debt securities may be issued as original issue discount senior
debt securities which bear no interest or interest at a rate which at the
time of issuance is below market rates ("Original Issue Discount
Securities"), to be sold at a substantial discount below their stated
principal amount due at the stated maturity of the senior debt securities.
There may be no periodic payments of interest on Original Issue Discount
Securities. In the event of an acceleration of the maturity of any Original
Issue Discount Security, the amount payable to the holder of the Original
Issue Discount Security upon acceleration will be determined in accordance
with the prospectus supplement, the terms of the security and the indenture,
but will be an amount less than the amount payable at the maturity of the
principal of the Original Issue Discount Security. Federal income tax
considerations with respect to Original Issue Discount Securities will be
described in the applicable prospectus supplement.

REGISTRATION AND TRANSFER

       Unless otherwise indicated in the applicable prospectus supplement,
senior debt securities will be issued only as Registered Securities. Senior
debt securities issued as Registered Securities will not have interest
coupons.

       Registered Securities (other than a Global Security) may be presented
for transfer, with the form of transfer endorsed thereon duly executed, or
exchanged for other senior debt securities of the same series at the office
of the security registrar specified in the indenture. The indenture provides
that, with respect to Registered Securities having The City of New York as a
place of payment, we will appoint a security registrar or co-security
registrar located in The City of New York for such transfer or exchange.
Transfer or exchange will be made without service charge, but we may require
payment of any taxes or other governmental charges.

BOOK-ENTRY SENIOR DEBT SECURITIES

       Senior debt securities of a series may be issued in whole or in part
in the form of one or more Global Securities. Each Global Security will be
deposited with, or on behalf of, a depositary identified in the applicable
prospectus supplement. Global Securities will be issued in registered form
and in either temporary or permanent form. Until exchanged in whole or in
part for the individual securities which it represents, a Global Security may
not be transferred except as a whole by the depositary for the Global
Security to a nominee of the depositary or by a nominee of the depositary to
the depositary or another nominee of the depositary or by the depositary or
any nominee to a successor depositary or any nominee of the successor. The
specific terms of the depositary arrangement for a series of senior debt
securities will be described in the applicable prospectus supplement.

PAYMENT AND PAYING AGENTS

       Unless otherwise indicated in an applicable prospectus supplement,
payment of principal of and any premium and interest on Registered Securities
will be made at the office of such paying agent or paying agents as we may
designate from time to time. In addition, at our option, payment of any
interest may be made by:

           -      check mailed to the address of the person entitled to the
                  payment at the address in the applicable security register;
                  or

           -      wire transfer to an account maintained by the person
                  entitled to the payment as specified in the applicable
                  security register.

       Unless otherwise indicated in an applicable prospectus supplement,
payment of any installment of interest on Registered Securities will be made
to the person in whose name such senior debt security is registered at the
close of business on the regular record date for such payment.

CONSOLIDATION, MERGER OR SALE OF ASSETS

       The indenture relating to the senior debt securities provides that we
may, without the consent of the holders of any of the senior debt securities
outstanding under the indenture, consolidate with, merge into or transfer our
assets substantially as an entirety to any person, provided that:

           -      any successor assumes our obligations on the senior debt
                  securities and under the indenture; and

           -      after giving effect to the consolidation, merger or
                  transfer, no Event of Default (as defined in the indenture)
                  will have happened and be continuing.

       Any consolidation, merger or transfer of assets substantially as an
entirety, which meets the conditions described above, would not create an
Event of Default which would entitle holders of the senior debt securities,
or the trustee acting on their behalf, to take any of the actions described
below under "--Events of Default, Waivers, Etc."

LEVERAGED AND OTHER TRANSACTIONS

       The indenture and the senior debt securities do not contain provisions
which would protect holders of the senior debt securities in the event we
engaged in a highly leveraged or other transaction which could adversely affect
the holders of senior debt securities.

MODIFICATION OF THE INDENTURE

       The indenture provides that, with the consent of the holders of not
less than a majority in aggregate principal amount of the outstanding senior
debt securities of each affected series, modifications and alterations of the
indenture may be made which affect the rights of the holders of the senior
debt securities. However, no modification or alteration may be made without
the consent of the holder of each senior debt security affected which would,
among other things,

                                       -10-

<PAGE>

           -      modify the terms of payment of principal of or any premium
                  or interest on the senior debt securities; or

           -      reduce the percentage in principal amount of outstanding
                  senior debt securities required to modify or alter the
                  indenture.

EVENTS OF DEFAULT, WAIVERS, ETC.

       An "Event of Default" with respect to senior debt securities of any
series is defined in the indenture to include:

           (1)    default in the payment of principal of or any premium on
                  any of the outstanding senior debt securities of that
                  series when due;

           (2)    default in the payment of interest on any of the
                  outstanding senior debt securities of that series when due
                  and continuance of such default for 30 days;

           (3)    default in the performance of any of our other covenants in
                  the indenture with respect to the senior debt securities of
                  such series and continuance of such default for 90 days
                  after written notice;

           (4)    certain events of bankruptcy, insolvency or reorganization
                  relating to us; and

           (5)    any other event that may be specified in a prospectus
                  supplement with respect to any series of senior debt
                  securities.

       If an Event of Default with respect to any series of outstanding
senior debt securities occurs and is continuing, either the trustee or the
holders of not less than 25% in aggregate principal amount of the outstanding
senior debt securities of such series may declare the principal amount (or if
such senior debt securities are Original Issue Discount Securities, the
portion of the principal amount as may be specified in the terms of that
series) of all senior debt securities of that series to be immediately due
and payable. The holders of a majority in aggregate principal amount of the
outstanding senior debt securities of any series may waive an Event of
Default resulting in acceleration of the senior debt securities, but only if
all Events of Default with respect to senior debt securities of such series
have been remedied and all payments due, other than those due as a result of
acceleration, have been made.

       If an Event of Default occurs and is continuing, the trustee may, in
its discretion, and at the written request of holders of not less than a
majority in aggregate principal amount of the outstanding senior debt
securities of any series and upon reasonable indemnity against the costs,
expenses and liabilities to be incurred in compliance with such request and
subject to certain other conditions set forth in the indenture will, proceed
to protect the rights of the holders of all the senior debt securities of
such series. Prior to acceleration of maturity of the outstanding senior debt
securities of any series, the holders of a majority in aggregate principal
amount of the senior debt securities may waive any past default under the
indenture except a default in the payment of principal of or any premium or
interest on the senior debt securities of that series.

       The indenture provides that upon the occurrence of an Event of Default
specified in clauses (1) or (2) of the first paragraph in this subsection, we
will, upon demand of the trustee, pay to it, for the benefit of the holder of
any senior debt security, the whole amount then due and payable on the
affected senior

                                       -11-

<PAGE>

debt securities for principal, premium, if any, and interest, if any. The
indenture further provides that if we fail to pay such amount upon demand,
the trustee may, among other things, institute a judicial proceeding for the
collection of those amounts.

       The indenture also provides that notwithstanding any of its other
provisions, the holder of any senior debt security of any series will have
the right to institute suit for the enforcement of any payment of principal
of or any premium or interest on the senior debt securities when due and that
such right will not be impaired without the consent of such holder.

       We are required to file annually with the trustee a written statement
of our officers as to the existence or non-existence of defaults under the
indenture or the senior debt securities.

SATISFACTION AND DISCHARGE

       The indenture provides, among other things, that when all senior debt
securities not previously delivered to the trustee for cancellation (1) have
become due and payable or (2) will become due and payable at their stated
maturity within one year, we may deposit with the trustee funds, in trust,
for the purpose and in an amount sufficient to pay and discharge the entire
indebtedness on the senior debt securities not previously delivered to the
trustee for cancellation. Those funds will include all principal, premium, if
any, and interest, if any, to the date of the deposit or to the stated
maturity, as applicable. Upon such deposit, the indenture will cease to be of
further effect except as to our obligations to pay all other sums due under
the indenture and to provide the officers' certificates and opinions of
counsel required under the indenture. At such time we will be deemed to have
satisfied and discharged the indenture.

GOVERNING LAW

       The indenture and the senior debt securities will be governed by, and
construed in accordance with, the laws of the State of New York.

REGARDING THE TRUSTEE

       Information concerning the trustee for a series of senior debt
securities will be set forth in the prospectus supplement relating to such
series of senior debt securities.

       We may have normal banking relationships with the trustee in the
ordinary course of business.

           -      any additional covenants or events of default not currently
                  included in the indenture relating to the subordinated debt
                  securities; and

           -      any other terms of the subordinated debt securities not
                  inconsistent with the provisions of the indenture.

       If any of the subordinated debt securities are sold for one or more
foreign currencies or foreign currency units or if the principal of or any
premium or interest on any series of subordinated debt securities is payable
in one or more foreign currencies or foreign currency units, the
restrictions, elections, tax consequences, specific terms and other
information with respect to that issue of subordinated debt securities and
those currencies or currency units will be described in the applicable
prospectus supplement.

       A judgment for money damages by courts in the United States, including
a money judgment based on an obligation expressed in a foreign currency, will
ordinarily be rendered only in U.S. dollars. New York statutory law provides
that a court shall render a judgment or decree in the foreign currency of the
underlying obligation and that the judgment or decree shall be converted into
U.S. dollars at the exchange rate prevailing on the date of entry of the
judgment or decree.

       Subordinated debt securities may be issued as Original Issue Discount
Securities, to be sold at a substantial discount below their stated principal
amount due at the stated maturity of the subordinated debt securities. There
may be no periodic payments of interest on Original Issue Discount
Securities. In the event of an acceleration of the maturity of any Original
Issue Discount Security, the amount payable to the holder of the Original
Issue Discount Security upon acceleration will be determined in accordance
with the prospectus supplement, the terms of the security and the indenture,
but will be an amount less than the amount payable at the maturity of the
principal of the Original Issue Discount Security. Federal income tax
considerations with respect to Original Issue Discount Securities will be
described in the applicable prospectus supplement.

REGISTRATION AND TRANSFER

       Unless otherwise indicated in the applicable prospectus supplement,
subordinated debt securities will be issued only as Registered Securities.
Subordinated debt securities issued as Registered Securities will not have
interest coupons.

       Registered Securities (other than a Global Security) may be presented
for transfer, with the form of transfer endorsed thereon duly executed, or
exchanged for other subordinated debt securities of the same series at the
office of the security registrar specified in the indenture. The indenture
provides that, with respect to Registered Securities having The City of New
York as a place of payment, we will appoint a security registrar or
co-security registrar located in The City of New York for such transfer or
exchange. Transfer or exchange will be made without service charge, but we
may require payment of any taxes or other governmental charges.

BOOK-ENTRY SUBORDINATED DEBT SECURITIES

       Subordinated debt securities of a series may be issued in whole or in
part in the form of one or more Global Securities. Each Global Security will
be deposited with, or on behalf of, a depositary identified in the applicable
prospectus supplement. Global Securities will be issued in registered form
and in either temporary or permanent form. Until exchanged in whole or in
part for the individual

                                       -15-

<PAGE>

securities which it represents, a Global Security may not be transferred
except as a whole by the depositary for the Global Security to a nominee of
the depositary or by a nominee of the depositary to the depositary or another
nominee of the depositary or by the depositary or any nominee to a successor
depositary or any nominee of the successor. The specific terms of the
depositary arrangement for a series of subordinated debt securities will be
described in the applicable prospectus supplement.

PAYMENT AND PAYING AGENTS

       Unless otherwise indicated in an applicable prospectus supplement,
payment of principal of and any premium and interest on Registered Securities
will be made at the office of such paying agent or paying agents as we may
designate from time to time. In addition, at our option, payment of any
interest may be made by:

           -      check mailed to the address of the person entitled to the
                  payment at the address in the applicable security register;
                  or

           -      wire transfer to an account maintained by the person
                  entitled to the payment as specified in the applicable
                  security register.

       Unless otherwise indicated in an applicable prospectus supplement,
payment of any installment of interest on Registered Securities will be made
to the person in whose name such subordinated debt security is registered at
the close of business on the regular record date for such payment.

SUBORDINATION

       The subordinated debt securities will be subordinated and junior in
right of payment to some of our other indebtedness (which may include senior
indebtedness for money borrowed) to the extent described in the applicable
prospectus supplement.

CONSOLIDATION, MERGER OR SALE OF ASSETS

       The indenture relating to the subordinated debt securities provides
that we may, without the consent of the holders of any of the subordinated
debt securities outstanding under the indenture, consolidate with, merge into
or transfer our assets substantially as an entirety to any person, provided
that:

           -      any successor assumes our obligations on the subordinated
                  debt securities and under the indenture; and

           -      after giving effect to the consolidation, merger or
                  transfer, no Event of Default (as defined in the indenture)
                  will have happened and be continuing.

       Any consolidation, merger or transfer of assets substantially as an
entirety, which meets the conditions described above, would not create an
Event of Default which would entitle holders of the subordinated debt
securities, or the trustee acting on their behalf, to take any of the actions
described below under "--Events of Default, Waivers, Etc."

                                       -16-

<PAGE>

LEVERAGED AND OTHER TRANSACTIONS

       The indenture and the subordinated debt securities do not contain
provisions which would protect holders of the subordinated debt securities in
the event we engaged in a highly leveraged or other transaction which could
adversely affect the holders of subordinated debt securities.

MODIFICATION OF THE INDENTURE

       The indenture provides that, with the consent of the holders of not
less than a majority in aggregate principal amount of the outstanding
subordinated debt securities of each affected series, modifications and
alterations of the indenture may be made which affect the rights of the
holders of the subordinated debt securities. However, no modification or
alteration may be made without the consent of the holder of each subordinated
debt security affected which would, among other things,

           -      modify the terms of payment of principal of or any premium
                  or interest on the subordinated debt securities;

           -      adversely modify the subordination terms of the
                  subordinated debt securities; or

           -      reduce the percentage in principal amount of outstanding
                  subordinated debt securities required to modify or alter
                  the indenture.

EVENTS OF DEFAULT, WAIVERS, ETC.

       An "Event of Default" with respect to subordinated debt securities of
any series is defined in the indenture to include:

           (1)    default in the payment of principal of or any premium on
                  any of the outstanding subordinated debt securities of that
                  series when due;

           (2)    default in the payment of interest on any of the
                  outstanding subordinated debt securities of that series
                  when due and continuance of such default for 30 days;

           (3)    default in the performance of any of our other covenants in
                  the indenture with respect to the subordinated debt
                  securities of such series and continuance of such default
                  for 90 days after written notice;

           (4)    certain events of bankruptcy, insolvency or reorganization
                  relating to us; and

           (5)    any other event that may be specified in a prospectus
                  supplement with respect to any series of subordinated debt
                  securities.

       If an Event of Default with respect to any series of outstanding
subordinated debt securities occurs and is continuing, either the trustee or
the holders of not less than 25% in aggregate principal amount of the
outstanding subordinated debt securities of such series may declare the
principal amount (or if such subordinated debt securities are Original Issue
Discount Securities, the portion of the principal amount as may be specified
in the terms of that series) of all subordinated debt securities of that
series to be immediately due and payable. The holders of a majority in
aggregate principal amount of the outstanding subordinated debt securities of
any series may waive an Event of Default resulting in

                                       -17-

<PAGE>

acceleration of the subordinated debt securities, but only if all Events of
Default with respect to subordinated debt securities of such series have been
remedied and all payments due, other than those due as a result of
acceleration, have been made.

       If an Event of Default occurs and is continuing, the trustee may, in
its discretion, and at the written request of holders of not less than a
majority in aggregate principal amount of the outstanding subordinated debt
securities of any series and upon reasonable indemnity against the costs,
expenses and liabilities to be incurred in compliance with such request and
subject to certain other conditions set forth in the indenture will, proceed
to protect the rights of the holders of all the subordinated debt securities
of such series. Prior to acceleration of maturity of the outstanding
subordinated debt securities of any series, the holders of a majority in
aggregate principal amount of the subordinated debt securities may waive any
past default under the indenture except a default in the payment of principal
of or any premium or interest on the subordinated debt securities of that
series.

       The indenture provides that upon the occurrence of an Event of Default
specified in clauses (1) or (2) of the first paragraph in this subsection, we
will, upon demand of the trustee, pay to it, for the benefit of the holder of
any subordinated debt security, the whole amount then due and payable on the
affected subordinated debt securities for principal, premium, if any, and
interest, if any. The indenture further provides that if we fail to pay such
amount upon demand, the trustee may, among other things, institute a judicial
proceeding for the collection of those amounts.

       The indenture also provides that notwithstanding any of its other
provisions, the holder of any subordinated debt security of any series will
have the right to institute suit for the enforcement of any payment of
principal of or any premium or interest on the subordinated debt securities
when due and that such right will not be impaired without the consent of such
holder.

       We are required to file annually with the trustee a written statement
of our officers as to the existence or non-existence of defaults under the
indenture or the subordinated debt securities.

SATISFACTION AND DISCHARGE

       The indenture provides, among other things, that when all subordinated
debt securities not previously delivered to the trustee for cancellation (1)
have become due and payable or (2) will become due and payable at their
stated maturity within one year, we may deposit with the trustee funds, in
trust, for the purpose and in an amount sufficient to pay and discharge the
entire indebtedness on the subordinated debt securities not previously
delivered to the trustee for cancellation. Those funds will include all
principal, premium, if any, and interest, if any, to the date of the deposit
or to the stated maturity, as applicable. Upon such deposit, the indenture
will cease to be of further effect except as to our obligations to pay all
other sums due under the indenture and to provide the officers' certificates
and opinions of counsel required under the indenture. At such time we will be
deemed to have satisfied and discharged the indenture.

GOVERNING LAW

       The indenture and the subordinated debt securities will be governed
by, and construed in accordance with, the laws of the State of New York.

                                       -18-

REGARDING THE TRUSTEE

       Information concerning the trustee for a series of subordinated debt
securities will be set forth in the prospectus supplement relating to such
series of subordinated debt securities.

       We may have normal banking relationships with the trustee in the
ordinary course of business.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

       Our authorized capital stock consists of (a) 100,000,000 shares of
common stock, having a par value of $1 per share, and (b) 25,000,000 shares
of preferred stock, without par value. As of October 31, 2000, 22,938,955
shares of common stock and 4,000 shares of preferred stock were outstanding.

COMMON STOCK

       The holders of common stock are entitled to one vote for each share
held of record on all matters submitted to a vote of shareholders. Cumulative
voting for the election of directors is allowed. Subject to preferences that
may be applicable to any outstanding series of preferred stock, holders of
common stock are entitled to receive equally dividends as they may be
declared by our board of directors out of funds legally available for the
payment of dividends. In the event of our liquidation or dissolution, holders
of common stock are entitled to share equally in all assets remaining after
payment of liabilities and the liquidation preference of any outstanding
series of preferred stock.

       Holders of common stock have no preemptive rights and have no rights
to convert their common stock into any other securities. All of the
outstanding shares of common stock are, and the shares of common stock we
sell in any offering will be, duly authorized, validly issued, fully paid and
nonassessable.

PREFERRED STOCK

       Our board of directors has the authority, without further action by
our shareholders, to issue shares of undesignated preferred stock from time
to time in one or more series and to fix the related number of shares and the
designations, voting powers, preferences, optional and other special rights,
and restrictions or qualifications of that preferred stock. The particular
terms of any series of preferred stock will be described in the prospectus
supplement relating to that series of preferred stock. The rights,
preferences, privileges and restrictions or qualifications of different
series of preferred stock may differ from common stock and other series of
preferred stock with respect to dividend rates, amounts payable on
liquidation, voting rights, conversion rights, redemption provisions, sinking
fund provisions and other matters. The issuance of additional series of
preferred stock could:

           -      decrease the amount of earnings and assets available for
                  distribution to holders of common stock;

           -      adversely affect the rights and powers, including voting
                  rights, of holders of common stock; and

           -      have the effect of delaying, deferring or preventing a
                  change in control.

NO PAR PREFERRED STOCK, SERIES 2000-A. We currently have 4,000 shares of No
Par Preferred Stock, Series 2000-A issued and outstanding. The shares of
preferred stock currently issued and outstanding are cumulative, convertible,
no par shares and are non-voting except as generally discussed below or as
otherwise required by law. The holders of our preferred stock are entitled to
receive cumulative quarterly cash dividends at a rate equal to 1% per year
computed on the basis of $1,000 per share plus an amount equal to any
dividend payable with respect to our common stock, multiplied by the number
of shares of

                                       -20-

<PAGE>

common stock into which each share of preferred stock is convertible.
Dividends on our preferred stock must be paid or declared and set apart for
payment before any dividends may be paid or declared and set apart for
payment on our common stock. In addition, no dividend may be declared or paid
with respect to our common stock unless the same dividend is declared and
paid with respect to our preferred stock.

       We have the authority to redeem our preferred stock in whole or in
part, at any time. The redemption price for the preferred stock is $1,000 per
share plus all accrued and unpaid dividends. Each share of preferred stock is
convertible at the option of the shareholder into shares of our common stock
at any time prior to July 7, 2005 and, unless redeemed, will be automatically
converted into shares of our common stock on July 7, 2005. Each share of
preferred stock is convertible into 28.57 shares (the liquidation preference
amount of $1,000 divided by the conversion price of $35.00 per share). Upon
delivery to a shareholder of a notice of redemption, the conversion price
will be adjusted to equal the lesser of the conversion price then in effect
and the current market price of our common stock on the redemption notice
date.

       The holders of our preferred stock are not entitled to any right to
vote at any meeting of our shareholders for the election of directors except
that whenever dividends accrued on the preferred stock remain unpaid in an
amount equivalent to four quarterly dividends, but less than eight, the
holders of the preferred stock, voting separately as one class for such
purpose, will be entitled at the next succeeding annual meeting of
shareholders to elect that number of directors as will constitute one-third
of the then board members, and the holders of common stock will be entitled
to elect the remaining directors. Whenever the accrued and unpaid dividends
on the preferred stock become equivalent to or exceed eight quarterly
dividends, the holders of the preferred stock, voting separately as one class
for such purpose, will be entitled to elect at the next succeeding annual
meeting of shareholders the smallest number of directors necessary to
constitute a majority of our board, and the holders of common stock will be
entitled to elect the remaining directors. After the accrued and unpaid
dividends are paid, the holders of the preferred stock will be divested of
these voting rights at the next succeeding annual meeting of shareholders.

       The consent of the holders of two-thirds of the outstanding shares of
our preferred stock, voting separately as one class for such purpose, is
required before we may:

           -      create or increase the authorized amount of any other class
                  of stock which will rank prior to the preferred stock in
                  respect of dividends or assets;

           -      reclassify shares of stock of any class ranking junior to
                  the preferred stock in respect of dividends or assets,
                  wholly or partially into shares of stock of any class
                  ranking on a parity with or prior to the preferred stock in
                  respect of dividends or assets;

           -      sell all or substantially all of our property and assets
                  to, or merge or consolidate into or with, any other
                  company; or

           -      make any distribution out of capital or capital surplus,
                  other than dividends payable in stock ranking junior to the
                  preferred stock in respect of dividends and assets, to
                  holders of stock ranking junior to the preferred stock in
                  respect of dividends or assets.

REGISTRATION RIGHTS

       In conjunction with our acquisition of Indeck Capital, Inc. in July
2000, we entered into a registration rights agreement with various new
shareholders (namely, Gerald R. Forsythe, Michelle R.

                                       -21-

<PAGE>

Fawcett, Marsha Fournier, Melissa S. Forsythe, Monica Breslow, and John W.
Salyer, Jr.). A total of 1,651,033 shares of common stock (assuming
conversion of our outstanding shares of preferred stock into common stock)
are currently covered by the registration rights agreement. In the event that
the new shareholders receive additional shares of our common stock and
convertible preferred stock pursuant to the earn-out provisions related to
the acquisition of Indeck, the additional shares of common stock, including
shares received upon conversion of preferred stock, will be covered by
the registration rights agreement.

       The registration rights granted under the registration rights
agreement entitle the parties to demand, at any time after June 30, 2002, a
total of three registrations of common stock, one of which can be a shelf
registration. The parties also have "piggyback" registration rights. The
registration rights agreement also contains customary provisions regarding
the payment of expenses by us and mutual indemnification agreements between
us and the new shareholders for securities law violations.

ANTI-TAKEOVER EFFECTS OF SOUTH DAKOTA LAW AND PROVISIONS OF OUR CHARTER AND
BYLAWS

       South Dakota law and our articles of incorporation and bylaws contain
certain provisions that might be characterized as anti-takeover provisions.
These provisions may make it more difficult to acquire control of us or
remove our management.

CONTROL SHARE ACQUISITIONS. The control share acquisition provisions of the
South Dakota Domestic Public Corporation Takeover Act provide generally that
the shares of a publicly held South Dakota corporation acquired by a person
that exceed the thresholds of voting power described below will have the same
voting rights as other shares of the same class or series only if approved by:

           -      the affirmative vote of the majority of all outstanding
                  shares entitled to vote, including all shares held by the
                  acquiring person; and

           -      the affirmative vote of the majority of all outstanding
                  shares entitled to vote, excluding all interested shares.

Each time an acquiring person reaches a threshold, an election must be held
as described above before the acquiring person will have any voting rights
with respect to shares in excess of such threshold. The thresholds which
require shareholder approval before voting powers are obtained with respect
to shares acquired in excess of such thresholds are 20%, 33 1/3% and 50%,
respectively. We have elected in our articles of incorporation not to be
subject to these provisions of South Dakota law.

BUSINESS COMBINATIONS. We are subject to the provisions of Section 47-33-17
of the South Dakota Domestic Public Corporation Takeover Act. In general,
Section 47-33-17 prohibits a publicly held South Dakota corporation from
engaging in a "business combination" with an "interested shareholder" for a
period of four years after the date that the person became an interested
shareholder unless the business combination or the transaction in which the
person became an interested shareholder is approved in a prescribed manner.
After the four year period has elapsed, the business combination must still
be approved, if not previously approved in the manner prescribed, by the
affirmative vote of the holders of a majority of the outstanding voting
shares exclusive, in some instances, of those shares beneficially owned by
the interested shareholder. Generally, a "business combination" includes a
merger, a transfer of 10% or more of the corporation's assets, an issuance or
transfer of stock equal to 5% or more of the aggregate market value of all of
the corporation's outstanding shares, the adoption of a plan of liquidation
or dissolution, or other transaction resulting in a financial benefit to the
interested shareholder. Generally,

                                       -22-

<PAGE>

an "interested shareholder" is a person who, together with affiliates and
associates, owns 10% or more of the corporation's voting stock. This
provision may delay, defer or prevent a change in control of us without the
shareholders taking further action.

       The South Dakota Domestic Public Corporation Takeover Act further
provides that our board, in determining whether to approve a merger or other
change of control, may take into account both the long-term as well as
short-term interests of us and our shareholders, the effect on our employees,
customers, creditors and suppliers, the effect upon the community in which we
operate and the effect on the economy of the state and nation.

FAIR PRICE PROVISION. Our articles of incorporation require the affirmative
vote of the holders of 80% or more of the outstanding shares of our voting
stock to approve any "business transaction" with any "related person" or any
"business transaction" in which a "related person" has an interest. However,
if a majority of the members of our board who are not affiliated with the
related party approve the business transaction, or if the cash or fair market
value of any consideration received by our shareholders pursuant to a
business transaction meets certain enumerated requirements, then the 80%
voting requirement will not be applicable. Generally, a "business
transaction" includes a merger, asset or stock sale. Generally, a "related
person" is defined as any person or entity that owns 10% or more of our
outstanding voting stock. The likely effect of this provision is to delay,
defer or prevent a change in control of us.

BOARD COMPOSITION. Our articles of incorporation and bylaws provide for a
staggered board of directors divided into three classes, with the term of office
of one class expiring each year. Our articles of incorporation and bylaws also
provide that our directors may be removed only for cause and by the affirmative
vote of the majority of the total number of members of the board of directors,
without including the director who is the subject of the removal determination.
The likely effect of our staggered board of directors and the limitation on the
removal of directors is an increase in the time required for the shareholders to
change the composition of our board of directors.

AUTHORIZED BUT UNISSUED SHARES. The authorized but unissued shares of our
common stock and preferred stock are available for future issuance without
shareholder approval. These additional shares may be used for a variety of
corporate purposes, including future public offerings to raise additional
capital, corporate acquisitions and employee benefit plans. The existence of
authorized but unissued and unreserved common stock and preferred stock could
also render more difficult or discourage an attempt to obtain control of us
by means of a proxy contest, tender offer, merger or otherwise.

       Our board of directors has no present intention to issue any new
series of preferred stock; however, our board has the authority, without
further shareholder approval, to issue one or more series of preferred stock
that could, depending on the terms of the series, either impede or facilitate
the completion of a merger, tender offer or other takeover attempt. Although
our board of directors is required to make any determination to issue such
stock based on its judgment as to the best interest of our shareholders, our
board could act in a manner that would discourage an acquisition attempt or
other transaction that some, or a majority, of the shareholders might believe
to be in their best interests or in which shareholders might receive a
premium for their stock over the then market price of such stock. Our board
of directors does not intend to seek shareholder approval prior to any
issuance of stock, unless otherwise required by law or the rules of the stock
exchange on which our common stock is listed.

SHAREHOLDER ACTION BY WRITTEN CONSENT MUST BE UNANIMOUS. South Dakota law
provides that any action which may be taken at a meeting of shareholders may
be taken without a meeting if a written consent, setting forth the action
taken, is signed by all of the shareholders entitled to vote with respect to

                                       -23-

<PAGE>

the action taken. This provision prevents holders of less than all of our
common stock from unilaterally using the written consent procedure to take
shareholder action.

TRANSFER AGENT AND REGISTRAR

       The transfer agent and registrar for our common stock is Wells Fargo
Shareowner Services.

                                       -24-

                             DESCRIPTION OF WARRANTS

OFFERED WARRANTS

       We may issue warrants that are debt warrants or equity warrants. We
may offer warrants separately or together with one or more additional
warrants or debt or equity securities or any combination of those securities
in the form of units, as described in the applicable prospectus supplement.
If we issue warrants as part of a unit, the accompanying prospectus
supplement will specify whether those warrants may be separated from the
other securities in the unit prior to the warrants' expiration date.

       DEBT WARRANTS. We may issue, together with debt securities or
separately, warrants for the purchase of debt securities on terms to be
determined at the time of sale.

       EQUITY WARRANTS. We may also issue warrants to purchase, including
warrant spreads, on terms to be determined at the time of sale, shares of our
common or preferred stock.

GENERAL TERMS OF WARRANTS

       The applicable prospectus supplement will contain, where applicable,
the following terms of and other information relating to the warrants and

SIGNIFICANT PROVISIONS OF THE WARRANT AGREEMENTS

       We will issue the warrants under one or more warrant agreements to be
entered into between us and a bank or trust company, as warrant agent, in one
or more series, which will be described in the prospectus supplement for the
warrants. The following summaries of significant provisions of the warrant
agreements and the warrants are not intended to be comprehensive, and holders
of warrants should review the detailed description of the relevant warrant
agreement included in any prospectus supplement.

MODIFICATIONS WITHOUT CONSENT OF WARRANTHOLDERS. We and the warrant agent may
amend the terms of the warrants and the warrant certificates without the
consent of the holders to:

           -      cure any ambiguity;

           -      cure, correct or supplement any defective or inconsistent
                  provision; or

           -      amend the terms in any other manner which we may deem
                  necessary or desirable and which will not adversely affect
                  the interests of the affected holders in any material
                  respect.

ENFORCEABILITY OF RIGHTS OF WARRANTHOLDERS. The warrant agents will act
solely as our agents in connection with the warrant certificates and will not
assume any obligation or relationship of agency or trust for or with any
holders of warrant certificates or beneficial owners of warrants. Any holder
of warrant certificates and any beneficial owner of warrants may, without the
consent of any other person, enforce by appropriate legal action, on its own
behalf, its right to exercise the warrants evidenced by the warrant
certificates in the manner provided for in that series of warrants or
pursuant to the applicable warrant agreement. No holder of any warrant
certificate or beneficial owner of any warrants will be entitled to any of
the rights of a holder of the debt securities or any other warrant property,
if any, purchasable upon exercise of the warrants, including, without
limitation, the right to receive the payments

                                       -26-

<PAGE>

on those debt securities or other warrant property or to enforce any of the
covenants or rights in the relevant indenture or any other similar agreement.

REGISTRATION AND TRANSFER OF WARRANTS. Subject to the terms of the applicable
warrant agreement, warrants in registered, definitive form may be presented for
exchange and for registration of transfer at the corporate trust office of the
warrant agent for that series of warrants, or at any other office indicated in
the prospectus supplement relating to that series of warrants, without service
charge. However, the holder will be required to pay any taxes and other
governmental charges as described in the warrant agreement. The transfer or
exchange will be effected only if the warrant agent for the series of warrants
is satisfied with the documents of title and identity of the person making the
request.

NEW YORK LAW TO GOVERN. The warrants and each warrant agreement will be governed
by, and construed in accordance with, the laws of the State of New York.

                              PLAN OF DISTRIBUTION

         We may sell the securities offered by this prospectus:

         -    through underwriters or dealers;
         -    through agents;
         -    directly to purchasers; or
         -    through a combination of any of these methods of sale.

Any underwriter, dealer or agent may be deemed to be an "underwriter" within the
meaning of the Securities Act of 1933.

         The applicable prospectus supplement relating to the securities will
set forth:

         -    their offering terms, including the name or names of any
              underwriters, dealers or agents;
         -    the purchase price of the securities and the net proceeds we may
              receive from the sale;
         -    any underwriting discounts, commissions and other items
              constituting compensation to underwriters, dealers or agents;
         -    any initial public offering price;
         -    any discounts or concessions allowed or reallowed or paid by
              underwriters or dealers to other dealers; and
         -    any securities exchanges on which the securities may be listed.

         If underwriters or dealers are used in the sale, the securities will be
acquired by the underwriters or dealers for their own account and may be resold
from time to time in one or more transactions,

         -    at a fixed price or prices which may be changed, or
         -    at market prices prevailing at the time of sale, or
         -    at prices related to such prevailing market prices, or
         -    at negotiated prices.

The securities may be offered to the public either through underwriting
syndicates represented by one or more managing underwriters or directly by one
or more of such firms. Unless otherwise set forth in the applicable prospectus
supplement, the obligations of underwriters or dealers to purchase the offered
securities will be subject to certain conditions precedent, and the underwriters
or dealers will be obligated to purchase all the offered securities if any are
purchased. Any public offering price and any discounts or concessions allowed or
reallowed or paid by underwriters or dealers to other dealers may be changed
from time to time.

         Securities may be sold directly by us or through agents designated by
us from time to time. Any agent involved in the offer or sale of the securities
in respect of which this prospectus is delivered will be named, and any
commissions payable by us to the agent will be set forth, in the applicable
prospectus supplement. Unless otherwise indicated in the applicable prospectus
supplement, any such agent will be acting on a best efforts basis for the period
of its appointment.

         If so indicated in the applicable prospectus supplement, we will
authorize underwriters, dealers or agents to solicit offers from certain
specified institutions to purchase securities from us at the public offering
price set forth in the prospectus supplement pursuant to delayed delivery
contracts providing for payment and delivery on a specified date in the future.
Such contracts will be subject to any conditions set


                                      -28-
<PAGE>

forth in the applicable prospectus supplement and the prospectus supplement
will set forth the commission payable for solicitation of such contracts. The
underwriters and other persons soliciting such contracts will have no
responsibility for the validity or performance of any such contracts.

         Underwriters, dealers and agents may be entitled under agreements
entered into with us to indemnification by us against certain civil liabilities,
including liabilities under the Securities Act of 1933, or to contribution by us
to payments which they may be required to make. The terms and conditions of such
indemnification will be described in an applicable prospectus supplement.
Underwriters, dealers and agents may be customers of, engage in transactions
with, or perform services for, us in the ordinary course of business.

         Each class or series of securities will be a new issue of securities
with no established trading market, other than our common stock, which is listed
on the New York Stock Exchange. We may elect to list any other class or series
of securities on any exchange, but are not obligated to do so. Any underwriters
to whom securities are sold by us for public offering and sale may make a market
in such securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. No assurance can be
given as to the liquidity of the trading market for any securities.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 47-5-27 of the South Dakota Codified Laws provides generally
that a corporation may indemnify any person who was or is a party to or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative in
nature, other than an action by or in the right of the corporation, by reason of
the fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, limited liability
company, partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with the action,
suit or proceeding if that person acted in good faith and in a manner that
person reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe such conduct was unlawful. The Bylaws of the
Registrant provide that, with respect to actions, suits or proceedings other
than by or in the right of the Registrant, the Registrant shall indemnify an
officer or director against liability incurred by such person as authorized
under the South Dakota Codified Laws. With respect to actions or suits by or in
the right of the Registrant, the Bylaws of the Registrant provide that the
Registrant shall indemnify any officer or director for any action or proceeding
he is made a party to by reason of the fact that he is or was a director or
officer of the Registrant, against expenses (including attorneys' fees) actually
and reasonably incurred by him in connection with the action or suit, if he
acted in good faith and in a manner he reasonably believed to be within the
scope of his authority and in, or not opposed to, the best interests of the
Registrant, except for those claims, issues or matters as to which such officer
or director shall have been adjudged to be liable to the Registrant, unless such
indemnification is deemed proper by a court. In addition, the Registrant has
entered into specific agreements with the directors and officers of the
Registrant providing for indemnification of such persons under certain
circumstances.


                                      II-1
<PAGE>

         The Registrant's Articles of Incorporation also eliminate the liability
of the Registrant's directors for monetary damages for breach of their fiduciary
duty as directors. This provision, however, does not eliminate a director's
liability (a) for any breach of the director's duty of loyalty to the Registrant
or its shareholders, (b) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (c) for any
violation of Sections 47-5-15 to 47-5-19, inclusive, of the South Dakota
Codified Laws, which relate in part to certain unlawful dividend payments or
stock redemptions or repurchases, or (d) for any transaction from which the
director derived an improper personal benefit.

         The Registrant carries directors' and officers' liability insurance to
insure its directors and officers against liability for certain errors and
omissions and to defray costs of a suit or proceeding against an officer or
director.

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 this 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 this Registration Statement.
              Notwithstanding the foregoing, any increase or decrease in volume
              of securities offered (if the total dollar value of securities
              offered would not exceed that which was registered) and any
              deviation from the low or high end of the estimated maximum
              offering range may be reflected in the form of prospectus filed
              with the Commission pursuant to Rule 424(b) if, in the aggregate,
              the changes in volume and price represent no more than a 20%
              change in the maximum aggregate offering price set forth in the
              "Calculation of Registration Fee" table in this effective
              Registration Statement; and

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

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

              (2)    That, for the purpose of determining any liability under
       the Securities Act of 1933, each such post-effective amendment shall be
       deemed to be a new registration statement


                                      II-3
<PAGE>

       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.

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

       (h)    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 referred to in Item 15 of
this Registration Statement, or otherwise, the Registrant has been advised that
in the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than 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 Act and
will be governed by the final adjudication of such issue.

       (i)    The undersigned Registrant undertakes that:

              (1)    For purposes of determining any liability under the
       Securities Act of 1933, the information omitted from the form of
       prospectus filed as a part of this Registration Statement in reliance
       upon Rule 430A and contained in a form of prospectus filed by the
       Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the
       Securities Act shall be deemed to be part of this Registration Statement
