                           SUMMARY INFORMATION -- Q&A

     This prospectus supplement and the accompanying base prospectus should be
read together. This summary highlights selected information from this prospectus
supplement and the accompanying base prospectus to help you understand the
preferred securities. You should carefully read this prospectus supplement and
the accompanying base prospectus to understand fully the terms of the preferred
securities, as well as the tax and other considerations that are important to
you in making a decision about whether to invest in the preferred securities.
You should pay special attention to the "Risk Factors" section beginning on page
S-6 of this prospectus supplement to determine whether an investment in the
preferred securities is appropriate for you.

     For your convenience, we make reference to sections in this prospectus
supplement and the accompanying base prospectus for more detailed information
regarding some of the terms and concepts used throughout this prospectus
supplement.

WHAT ARE THE PREFERRED SECURITIES?

     Each preferred security represents an undivided beneficial interest in the
assets of the trust. The underwriters are offering                     preferred
securities at a public offering price of $25 for each preferred security. See
"Underwriting" in this prospectus supplement.

WHO IS THE TRUST?

     Consumers Energy Company Financing III is a Delaware business trust. The
trust will sell its preferred securities to the public and its common securities
to Consumers. The trust will use the proceeds from these sales to buy a series
of        % subordinated debentures due                from Consumers with the
same economic terms as the preferred securities.

     There will be four trustees of the trust. Two of the trustees are employees
or officers of Consumers, referred to as the "regular trustees." Bank of New
York will act as the property trustee of the trust and Bank of New York
(Delaware) will act as the Delaware trustee, in each case until removed or
replaced by the holder of the common securities. For the purposes of compliance
with the provisions of the Trust Indenture Act, Bank of New York will also act
as indenture trustee under the guarantee.

WHO IS CONSUMERS ENERGY COMPANY?

     Consumers is a public utility that provides natural gas and electricity to
almost six million of the nine and one-half million residents in Michigan's
Lower Peninsula. Consumers' electric operations include the generation,
purchase, transmission and distribution of electricity. It provides electric
services in 61 of the 68 counties of Michigan's Lower Peninsula. Consumers' gas
utility operation purchases, transports, stores and distributes natural gas. It
renders gas sales and delivery service in 54 of the 68 counties in Michigan's
Lower Peninsula. At year end 1998, Consumers provided service to 1.6 million
electric customers and 1.5 million gas customers. Consumers' consolidated
operating revenue in 1998 was $3.7 billion. Of Consumers' operating revenue, 70%
was generated from its electric utility business, 29% from its gas utility
business, and 1% from its non-utility business.

WHEN WILL YOU RECEIVE QUARTERLY DISTRIBUTIONS ON THE PREFERRED SECURITIES?

     If you purchase the preferred securities, you will be entitled to receive
cumulative cash distributions at an annual rate of      % of the liquidation
amount of $25 per preferred security. Distributions will accumulate from
               , 1999, and will be payable quarterly in arrears on
               ,                ,                , and                of each
year, beginning                1999.

WHEN CAN PAYMENT OF YOUR DISTRIBUTIONS BE DEFERRED?

     Consumers may, on one or more occasions, defer interest payments on the
debentures for up to 20 consecutive quarterly periods unless an event of default
under the debentures has occurred and is
                                       S-3
<PAGE>   6

continuing. See "Description of Securities -- Certain Terms of the
Debentures -- Option to Extend Interest Payment Period," in this prospectus
supplement. A deferral of interest payments cannot extend beyond the stated
maturity date of the debentures (which is                ).

     If Consumers defers interest payments on the debentures, the trust will
also defer its distributions on the preferred securities to you. During this
deferral period, distributions will continue to accumulate on the preferred
securities at an annual rate of      % of the liquidation amount of $25 per
preferred security. Also, the deferred distributions will themselves accumulate
distributions at an annual rate of      % (to the extent permitted by law). Once
Consumers makes all deferred interest payments on the debentures, with accrued
interest, it may again defer interest payments on the debentures if no event of
default under the debentures has then occurred and is continuing.

     During any period in which Consumers defers interest payments on the
debentures, Consumers will not be permitted to, with some exceptions:

     - pay a dividend or make any other payment or distribution on its capital
       stock;

     - redeem, purchase or make a liquidation payment on any of its capital
       stock; or

     - make a principal, premium or interest payment, or repurchase or redeem,
       any of its debt securities that rank equal with or junior to the
       debentures.

     If Consumers defers interest payments on the debentures, you will be
required to accrue interest income for United States federal income tax purposes
before you receive cash distributions. See "Certain United States Federal Income
Tax Consequences" and "Risk Factors -- Ability to defer distributions has tax
consequences for you and may affect the trading price of the preferred
securities" in this prospectus supplement.

WHEN CAN THE TRUST REDEEM THE PREFERRED SECURITIES?

     The trust will redeem all of the outstanding preferred securities when the
debentures are paid either at maturity on                     , or upon early
redemption.

     Consumers will pay the debentures at maturity on                     .
Consumers may redeem, before their maturity at a redemption price equal to 100%
of the principal amount being redeemed plus accrued and unpaid interest to the
date of redemption:

     - all or some of the debentures on one or more occasions any time on or
       after           ; or

     - all but not some of the debentures before                     , if
       certain changes in tax or investment company law occur or will occur
       within 90 days (each of which is a "special event". See "Special Event
       Redemption" in this prospectus supplement.

     If Consumers redeems any debentures before their maturity, the trust will
use the cash it receives on the redemption of the debentures to redeem,
proportionately, preferred securities and common securities having a total
liquidation amount equal to the total principal amount of the debentures
redeemed, unless an event of default under the amended and restated declaration
of trust, has occurred and is continuing. In such a case, the preferred
securities will be redeemed before any common securities. An event of default
with respect to the debentures or the guarantee constitutes an event of default
under the trust agreement. See "Description of Securities - Trust Preferred
Securities -- Effect of Obligations Under the Debt Securities and the
Guarantees" and "The Guarantees -- Events of Default" in the accompanying base
prospectus for a description of an event of default in respect of the debentures
and the guarantee, respectively. The redemption price will be equal to $25 per
security plus any accumulated distributions.

WHAT IS THE NATURE OF CONSUMERS' GUARANTEE OF THE PREFERRED SECURITIES?

     Consumers will fully and unconditionally guarantee the preferred securities
through a combination of its obligations:

     - to make payments on the debentures;

     - under its guarantee of the preferred securities; and

     - under the trust agreement and its junior subordinated indenture.

     If Consumers does not make a required payment on the debentures, the trust
will not have sufficient funds to make the related payment on the preferred
securities. The guarantee does not cover payments on the preferred securities
when the trust does not have sufficient funds to make such payments. Consumers'
obligations under the debentures are junior to its obligations to make payments
on its senior indebtedness and Consumers' obligations under the guarantee are
junior to its obligations to make payments on its senior indebtedness in the
same manner as the debentures. See "Risk Factors -- Consumers' obligations under
the debentures and the guarantee are subordinated" in this prospectus
supplement.

WHEN CAN THE DEBENTURES BE DISTRIBUTED TO YOU?

     Consumers, as the sponsor of the trust, has the right to dissolve the trust
at any time. If Consumers exercises this right to dissolve the trust, the trust,
after satisfying any creditors it has, will be liquidated by distribution of the
debentures to holders of the preferred securities and the common securities.

WHAT HAPPENS IF THE TRUST IS DISSOLVED AND THE DEBENTURES ARE NOT DISTRIBUTED?

     The trust may also be dissolved in circumstances where the debentures will
not be distributed to you. In those situations, after satisfying any of its
creditors, the trust will be obligated to pay in cash the liquidation amount of
$25 for each preferred security plus accumulated distributions to the date such
payment is made. The trust will be able to make this liquidation distribution
only if the debentures are paid or redeemed by Consumers.

WILL THE PREFERRED SECURITIES BE LISTED ON A STOCK EXCHANGE?

     The trust will apply to have the preferred securities listed on the New
York Stock Exchange under the symbol "       ." If approved for listing, trading
of the preferred securities on the New York Stock Exchange is expected to
commence within 30 days after the preferred securities are first issued. You
should be aware that the listing of the preferred securities will not
necessarily ensure that a liquid trading market will be available for the
preferred securities.

     If the trust distributes the debentures, Consumers will use its best
efforts to list them on the New York Stock Exchange or any other exchange or
other organization on which the preferred securities are then listed.

IN WHAT FORM WILL THE PREFERRED SECURITIES BE ISSUED?

     The preferred securities will be represented by one or more global
securities that will be deposited with, or on behalf of, and registered in the
name of, The Depository Trust Company, New York, New York ("DTC") or its
nominee. This means that you will not receive a certificate for your preferred
securities. Instead, you will hold your interest through DTC's book-entry
system. The trust expects that the preferred securities will be ready for
delivery through DTC on or about                     , 1999.

                                  RISK FACTORS

     Your investment in the preferred securities will involve certain risks. You
should carefully consider the following discussion of risks, and the other
information included or incorporated by reference in this prospectus supplement
and the accompanying base prospectus, before deciding whether an investment in
the preferred securities is suitable for you. The risks described below are not
the only ones facing the trust and Consumers. Additional risks not presently
known to the trust and Consumers or that they currently deem immaterial may also
impair Consumers' business.

               RISK FACTORS RELATING TO THE PREFERRED SECURITIES

CONSUMERS' OBLIGATIONS UNDER THE DEBENTURES AND THE GUARANTEE ARE SUBORDINATED

     Consumers' obligations under the debentures are unsecured and will rank
junior in priority of payment to Consumers' senior indebtedness. This means that
Consumers may not make any payments of principal or interest on the debentures
if it defaults on a payment on its senior indebtedness. Also, payments on the
debentures may be blocked for up to 180 days in the event of certain non-payment
defaults by Consumers on its senior indebtedness. For more information on the
subordination provisions, see "Certain Terms of the Debentures" in this
prospectus supplement. In the event of the bankruptcy, liquidation or
dissolution of Consumers, its assets would be available to pay obligations under
the debentures only after all payments had been made on its senior indebtedness.
At                     , 1999, as if on that date Consumers and the trust had
issued and sold the preferred securities and the debentures and applied the
estimated net proceeds thereof as described in this prospectus supplement, the
total amount of Consumers' senior indebtedness would have been approximately
$          . See "Capitalization" and "Use of Proceeds" in this prospectus
supplement.

     Consumers' obligations under the guarantee are unsecured and will rank in
priority of payment as follows:

     - junior to all of Consumers' senior indebtedness in the same manner as the
       debentures; and

     - equally with certain guarantees previously issued by Consumers with
       respect to certain preferred securities and with all other guarantees of
       securities issued by affiliates of Consumers similar to the preferred
       securities issued by the trust.

     This means that Consumers cannot make any payments on the guarantee if it
defaults on a payment of any of its senior indebtedness. In the event of the
bankruptcy, liquidation or dissolution of Consumers, its assets would be
available to pay obligations under the guarantee only after all payments had
been made on its senior indebtedness.

     Neither the debentures nor the guarantee will limit the ability of
Consumers and its subsidiaries to incur additional indebtedness, including
indebtedness that ranks senior in priority of payment to the debentures and the
guarantee.

     For more information, see "Certain Terms of the Debentures --
Subordination" in this prospectus supplement and "Description of
Securities -- The Guarantees" in the accompanying base prospectus.

THE GUARANTEE COVERS PAYMENTS ONLY IF THE TRUST HAS CASH AVAILABLE

     The ability of the trust to pay distributions on the preferred securities,
the redemption price of the preferred securities and the liquidation amount of
each preferred security is solely dependent upon Consumers making the related
payments on the debentures when due. If Consumers defaults on its obligation to
pay principal (including redemption payments) or interest on the debentures, the
trust will not have sufficient funds to pay distributions, the redemption price
or the liquidation amount of each preferred security. In those circumstances,
you will not be able to rely upon the guarantee for payment of these amounts
because the guarantee covers such payment only when the trust has sufficient
funds on hand but fails to make such payment.

                                       S-6
<PAGE>   9

     Instead, you may:

     - seek legal redress against Consumers directly or seek other remedies to
       collect your proportionate share of payments owed; or

     - rely on the property trustee to enforce the trust's rights under the
       debentures.

ABILITY TO DEFER DISTRIBUTIONS HAS TAX CONSEQUENCES FOR YOU AND MAY AFFECT THE
TRADING PRICE OF THE PREFERRED SECURITIES

     So long as no event of default under the debentures has occurred and is
continuing, Consumers may, on one or more occasions, defer interest payments to
the trust on the debentures as described in this prospectus supplement. See
"Certain Terms of the Debentures -- Option to Extend Interest Payment Period" in
this prospectus supplement. If Consumers defers interest payments on the
debentures, the trust will defer distributions on the preferred securities to
you during any deferral period. If Consumers defers interest payments on the
debentures, you will be required to accrue interest income, as original issue
discount or "OID," in respect of the deferred stated interest allocable to your
share of the preferred securities for United States federal income tax purposes.
As a result, you will include such income in gross income for United States
federal income tax purposes prior to the receipt of any cash distributions. In
addition, you will not receive cash from the trust related to such income if you
dispose of your preferred securities prior to the record date on which
distributions of such amounts are made.

     Consumers has no current intention of deferring interest payments on the
debentures. However, if Consumers exercises its right to do so in the future,
the preferred securities may trade at a price that does not fully reflect the
value of accrued but unpaid interest on the debentures. If you sell the
preferred securities during an interest deferral period, you may not receive the
same return on investment as someone else who continues to hold the preferred
securities. In addition, the existence of Consumers' right to defer payments of
interest on the debentures may mean that the market price for the preferred
securities (which represent an undivided beneficial interest in the debentures)
may be more volatile than other securities that do not have this right.

     See "Certain United States Federal Income Tax Consequences" in this
prospectus supplement for more information.

PREFERRED SECURITIES MAY BE REDEEMED BEFORE           , IF A SPECIAL EVENT
OCCURS

     Upon the occurrence of a Special Event before           , Consumers may
redeem all but not some of the debentures. The redemption price will equal 100%
of the principal amount of the debentures plus any accrued and unpaid interest
to the redemption date. The trust will use the cash it receives on any such
redemption of the debentures to redeem an equivalent liquidation amount of the
preferred securities and the common securities on a proportionate basis, unless
an event of default under the trust agreement has occurred and is continuing. In
such a case, the preferred securities will be redeemed before any common
securities.

     See "Certain Terms of the Preferred Securities -- Special Event Redemption"
in this prospectus supplement for more information.

PREFERRED SECURITIES MAY BE REDEEMED ON OR AFTER           , AT CONSUMERS OPTION

     At Consumers' option, some or all of the debentures may be redeemed at any
time on or after           at a redemption price equal to 100% of the principal
amount to be redeemed plus any accrued and unpaid interest to the redemption
date. See "Certain Terms of the Debentures -- Redemption" in this prospectus
supplement. You should assume that Consumers will exercise its redemption option
when prevailing interest rates at the time are lower than the interest rate on
the debentures, so that the redemption proceeds generally will not be able to be
reinvested in a comparable security at as high a rate. If Consumers exercises
such redemption option, the trust will use the cash it receives on the
redemption of the debentures to redeem an equivalent liquidation amount of the
preferred securities and the common
                                       S-7
<PAGE>   10

securities on a proportionate basis, unless an event of default under the trust
agreement has occurred and is continuing. In such a case, the preferred
securities will be redeemed before any common securities.

     See "Certain Terms of the Preferred Securities -- Redemption" in this
prospectus supplement for more information.

DISTRIBUTION OF DEBENTURES MAY HAVE A POSSIBLE ADVERSE EFFECT ON TRADING PRICE

     Consumers has the right to dissolve the trust at any time. If Consumers
exercises this right, the trust, after satisfying any creditors it has, will be
liquidated by distribution of the debentures to holders of the preferred
securities and the common securities. Under current United States federal income
tax laws, a distribution of debentures to you on the dissolution of the trust
would not be a taxable event to you. See "Certain United Stated Federal Income
Tax Consequences -- Receipt of Debentures or Cash Upon Liquidation of the Trust"
in this prospectus supplement for more information.

     Consumers has no current intention of causing the dissolution of the trust
and the distribution of the debentures. However, there are no restrictions on
its ability to do so at any time. Consumers anticipates that it would consider
exercising this right in the event that expenses associated with maintaining the
trust were substantially greater than currently expected, such as if a Special
Event occurred. Consumers cannot predict the other circumstances under which
this right would be exercised.

     Although Consumers will use its best efforts to list the debentures on the
New York Stock Exchange (or any other exchange or organization on which the
preferred securities are then listed) if they are distributed, we cannot assure
you that the debentures will be approved for listing or that a liquid trading
market for the debentures will be available.

     Consumers cannot predict the market prices for the debentures that may be
distributed. Accordingly, the debentures that you receive on a distribution, or
the preferred securities you hold pending such a distribution, may trade at a
discount to the price that you paid to purchase the preferred securities.

     Because you may receive debentures, you should make an investment decision
with regard to the debentures in addition to the preferred securities. You
should carefully review all the information regarding the debentures contained
in this prospectus supplement and the accompanying base prospectus. See "Certain
United States Federal Income Tax Consequences -- Receipt of Debentures or Cash
Upon Liquidation of the Trust" in this prospectus supplement for more
information.

LIMITED VOTING RIGHTS

     You will have limited voting rights. In general, unless an event of default
under the trust agreement has occurred and is continuing, only Consumers may
elect or remove any of the trustees, and in no event may holders of the
preferred securities remove the regular trustees.

     See "Consumers Energy Company Trusts" in the accompanying base prospectus
and "Certain Terms of the Preferred Securities -- Voting Rights" in this
prospectus supplement for more information.

                       RISK FACTORS RELATING TO CONSUMERS

CONSUMERS' COMPETITION AND REGULATORY RESTRUCTURING

     Federal and state regulation of electric and natural gas utilities,
interstate pipelines and independent electric power producers has changed
dramatically in the last two decades and could continue to change over the next
several years. In general, such regulatory changes have resulted and will
continue to result in increased competition in Consumers' domestic energy
businesses. Increased opportunities will present themselves as the changes
unfold.

     The regulatory changes have been particularly significant in Consumers'
natural gas businesses. As a result of these changes, gas distribution companies
like Consumers transport the natural gas commodity

                                       S-8
<PAGE>   11

which is sold to customers by competitors like gas producers, marketers and
others. Consumers' current gas commodity rates are frozen until March 2001,
under a pilot program which allows Consumers to earn a margin on the commodity
provided it can continue to purchase gas at prices below that allowed in its
rates. The full impact of competition remains to be seen, particularly if and
when Consumers' existing pilot program providing other gas suppliers direct
access to some of its customers is extended to all Consumers' gas customers by
way of legislation or regulatory action. Further changes in federal and state
regulation of the natural gas industry could also adversely affect Consumers'
gas utility business.

     Federal regulation of electric sales and transmission of electricity has
also changed significantly since the 1992 enactment of the Energy Policy Act.
This legislation and the Federal Energy Regulatory Commission regulations which
followed have effectively granted independent power producers and electricity
marketers "direct access" to the interstate electric transmission systems owned
by electric utilities. All electric utilities are required to offer transmission
services to new market entrants on a non-discriminatory basis. As a result,
wholesale electricity markets have become much more competitive and wholesale
prices have become more volatile, affecting both purchasers and sellers of power
at wholesale. While this has not adversely affected Consumers to date, and does
present Consumers with the potential opportunity to expand the market reach for
electric power sales by Consumers, the rapidly changing nature of the
marketplace creates the opportunity for competitors to market electricity to
Consumers' wholesale customers.

     In addition to the changes in federal regulation of the electric industry,
state regulation of the retail electric utility business is in the process of
undergoing significant changes. For example, the Michigan Public Service
Commission ("MPSC") issued several orders in 1997, 1998 and 1999 restructuring
the electric power industry in Michigan. Under these orders which Consumers has
voluntarily agreed to implement, Consumers will allow certain customers to elect
to purchase electric power directly from other suppliers, such as independent
power producers, power marketers and other utilities. Consumers will continue to
transmit and distribute such power purchases to the end-use retail customers.
Importantly, the orders provide for full recovery by Consumers of its stranded
costs. This electric customer choice program commenced in September 1999 and
will be phased in to cover 750 megawatts of Consumers' retail market by 2001. On
January 1, 2002, all of Consumers' electric customers will have this option. It
is not possible at this time to predict the extent to which Consumers' customers
will elect this option or what the ultimate financial impact will be to
Consumers.

     Several bills relative to electric industry restructuring were introduced
in the Michigan House of Representatives and Senate for consideration in the
1999-2000 legislative session. Although Consumers has not specifically supported
any of these bills, Consumers believes legislation is desirable to provide
statutory support for MPSC orders. Consumers is uncertain as to whether
legislation will be enacted and what effect any enacted legislation will have on
Consumers. Similar uncertainty exists with respect to the possibility that
federal legislation restructuring the electric power industry will be enacted. A
variety of bills changing existing federal regulation of the industry and,
potentially, affecting state regulation have been introduced in the Congress in
recent years. None has been enacted.

     Adverse federal or state legislation or adverse future rate determinations
by the MPSC could result in Consumers being unable to fully recover its current
investment in electric generating facilities and the cost of purchased power.

RISK OF YEAR 2000 NONCOMPLIANCE

     Many existing computer programs were designed and developed without
considering the upcoming change in the century, which could lead to the failure
of computer applications or create erroneous results by or at the year 2000. The
year 2000 issue is a broad business issue, whose impact extends beyond
traditional computer hardware and software to possible failure of automated
plant systems and instrumentation as well as to third party businesses. Also,
there can be no guarantee that suppliers, large customers and other third
parties of importance to Consumers' business operations will successfully
reprogram or replace, and test, all of their own computer hardware, software and
process control systems

                                       S-9
<PAGE>   12

to ensure such systems are year 2000 compliant. Failure by Consumers, any of the
entities listed above, or other institutions such as governments to become year
2000 compliant on a timely basis or to recover from system interruptions on a
timely basis could have a material adverse effect on Consumers' financial
position and results of operations.

RESULTS COULD DIFFER MATERIALLY FROM CERTAIN FORWARD-LOOKING STATEMENTS

     On one or more occasions, Consumers may make statements regarding
Consumers' assumptions, projections, expectations, intentions or beliefs about
future events. These statements are intended as forward-looking statements under
the Private Securities Litigation Reform Act of 1995. Consumers cautions that
these statements may and often do differ materially from actual results. Some of
the factors that could cause actual results to differ materially from those
expressed or implied in any forward-looking statements are:

     - ability to achieve operating synergies and revenue enhancements;

     - national, regional and local economic, competitive and regulatory
       conditions and developments;

     - capital and financial market conditions, including interest rates;

     - weather conditions;

     - adverse legislative, regulatory or legal decisions, including
       environmental laws and regulations;

     - the pace of deregulation of the natural gas and electric industries;

     - energy markets, including the timing and extent of changes in commodity
       prices for oil, coal, natural gas, natural gas liquids, electricity and
       certain related products;

     - the timing and success of business development efforts;

     - nuclear power performance and regulation;

     - technological developments in energy production, delivery and usage; and

     - other uncertainties, all of which are difficult to predict and many of
       which are beyond Consumers' control.

                              RECENT DEVELOPMENTS

     The MPSC issued an order on August 17, 1999 finding that it has
jurisdiction to approve rates, terms, and conditions for retail wheeling of
electricity (also known as "electric customer choice") if a utility voluntarily
chooses to offer that service. The MPSC issued this order after Consumers and
other parties submitted the briefs requested by the MPSC concerning the effects
of a June 29, 1999 Michigan Supreme Court decision. That Court found that the
MPSC does not have the statutory authority to order a mandatory retail wheeling
program. The August 17th order also requested that Consumers file a statement as
to whether it intended to continue with its electric customer choice program. On
September 1, 1999, Consumers filed a statement reaffirming its decision to
continue carrying out the electric customer choice program as previously
approved by the MPSC. The Association of Businesses Advocating Tariff Equity
("ABATE") and the Michigan Attorney General have each appealed the August 17th
order to the Michigan Court of Appeals. The issues raised by the MPSC's August
17th order could be resolved by the regulatory process, the appellate court or
by legislation codifying the retail wheeling and related stranded cost recovery
issues with the exact resolution being uncertain at this time.

     In March 1999, Consumers signed a long-term electric power sales agreement
to resell to PECO Energy Company until September 2007 its capacity and energy
purchases under the long-term Power Purchase Agreement between Consumers and the
Midland Cogeneration Venture Limited Partnership (the "MCV PPA"). In March 1999,
Consumers also filed an application with the MPSC for accounting and rate-making
approvals related to the PECO agreement. If used as an offset to electric
customers

                                      S-10
<PAGE>   13

stranded cost responsibility, Consumers estimates that there could be a
reduction of as much as $58 million (on a net present value basis) of stranded
cost related to the MCV PPA. In an order issued in April 1999, the MPSC
conditionally approved the requests for accounting and rate-making treatment
"but only to the extent that the resulting rates are lower than or equal to the
amount that they would be absent the PECO agreement." In response to Consumers'
and other parties' requests for clarification and rehearing, in an August 31,
1999 opinion, the MPSC partially granted the relief Consumers requested on
rehearing and attached certain additional conditions to its approval. Those
conditions relate to Consumers' continued decision to carry out the electric
customer choice program (which Consumers has affirmed as discussed above) and a
determination to revise Consumers' capacity solicitation process (which
Consumers has filed but is awaiting an MPSC decision). The August 31st opinion
is a companion order to a power supply cost reconciliation order issued on the
same date in another case. This order affects the level of frozen power supply
costs recoverable in rates during future years when the transaction with PECO
would be taking place. On September 30, 1999 Consumers filed motions for
clarification of the orders relating to the PECO agreement.

     On November 12, 1997 ABATE filed a complaint with the MPSC that alleged
Consumers' electric earnings are more than its authorized rate of return and
sought an immediate reduction in Consumers' electric rates. The MPSC staff
investigated the complaint and concluded in an April 1998 report that no formal
rate proceeding was warranted at that time. The MPSC has now scheduled this
matter for further proceedings that should lead to more definitive MPSC
resolution in the first quarter of 2000, absent prior agreement among the
parties. In those proceedings, ABATE and intervenors bear the burden of
convincing the MPSC to reduce electric rates, which will otherwise remain
unchanged. In its testimony filed in this case, ABATE claimed that Consumers'
had approximately $189 million in excess revenues for 1998. In its testimony
MPSC staff stated that 1998 book results show excess revenues of $118 million
when actual results were compared to the previously authorized electric return
on equity, but recognized that no definitive conclusion could be reached from
such a simplistic computation about the proper level of future retail electric
rates. The MPSC staff presentation anticipated Consumers would file testimony
and exhibits using traditional ratemaking adjustments and normalizations which
would negate ABATE's claim of excessive earnings. Consumers has filed such
testimony showing that after such normalizations, there is a revenue deficiency
of approximately $3 million. The MPSC staff offered several alternatives for the
MPSC to consider. They involved several different refunds or reductions which
the MPSC could consider separately or in combination, but which, if made would
not result in a permanent future reduction in electric rates in the amount being
sought by ABATE. Consumers believes that ABATE, through its testimony, has not
met its burden of proving that a reduction in rates is appropriate. It also
believes that ABATE's request for refunds from 1995 to present is inappropriate
or unlawful because no such retroactive rate adjustment has ever been granted by
the MPSC in the past. On October 13, 1999, the MPSC granted Consumers' request
to deny questioning in this case concerning its power supply costs, and stated
that such matters were sufficiently addressed and determined in an earlier MPSC
order whereby such costs were frozen.

     The MPSC issued an order on September 28, 1999 relating to the 1997-98
heating year finding that Consumers did not demonstrate that its decision to
increase spot market and short-term gas purchases beyond the levels filed in its
gas cost recovery plan was reasonable and prudent, and disallowed recovery of
approximately $6.5 million of gas costs. The MPSC concluded that Consumers must
refund approximately $11.6 million (including interest) to its customers during
the December 1999 billing cycle. Consumers established a reserve for the refund
in the third quarter of 1999. Consumers has not yet determined whether to seek a
rehearing with the MPSC or appeal the MPSC's order with the Michigan Court of
Appeals.

     Consumers' customers reached a record peak demand for electricity of 7,460
megawatts on July 30, 1999, surpassing the previous record of 7,315 MW by 2%.
Consumers satisfied this peak demand by utilizing its owned generating capacity
and long-term purchase contracts, and by taking actions such as exercising
rights under existing short-term option contracts, interrupting supply under its
interruptible contracts, exercising customer self-generation and load-shifting
options, and making public requests to its

                                      S-11
<PAGE>   14

customers to conserve energy. By carrying out these actions, none of Consumers'
customers experienced an involuntary reduction of firm load due to supply
shortages.

     In October 1999, Consumers announced that it is making progress in
discussions with its major commercial and industrial customers, which, if
successful, would result in agreement on the need for, and substance of,
electric restructuring legislation in Michigan and have the effect of resolving
Consumers' rate proceedings pending before the MPSC. While there are no
assurances that an agreement or legislation will result, Consumers is optimistic
that a positive outcome of the discussions can be achieved.

     The Federal Clean Air Act, as amended, limits emissions of sulfur dioxide
and nitrogen oxides and requires emissions and air quality monitoring. In 1997
the EPA revised the national air quality standards to impose further limitations
on nitrogen oxide and small particulate-related emissions. In May 1999, a United
States Court of Appeals ruled however, that the EPA's revision of the standards
was an unconstitutional delegation of legislative power. As a result, the
standards will not be implemented under the 1997 rule. The EPA has requested a
rehearing of this ruling.

     In September 1998, based in part upon the 1997 standards, the EPA
Administrator issued final regulations requiring the State of Michigan to
further limit nitrogen oxide emissions. The State of Michigan filed a lawsuit
objecting to the extent of the required emission reductions and requesting an
extension of the submission date. In May 1999, the United States Court of
Appeals for the District of Columbia granted an indefinite stay of the
submission date for the State of Michigan's implementation plan. Based upon the
recent court rulings, it is unlikely that the State of Michigan will establish
Consumers' nitrogen oxide emissions reduction target until late 1999. Until this
target is established, the estimated cost of compliance discussed below is
subject to revision.

     The preliminary estimate of capital expenditures to reduce nitrogen
oxide-related emissions to the level proposed by the State of Michigan for
Consumers' fossil-fueled generating units ranges from approximately $150 million
to $290 million, in 1999 dollars. If Consumers had to meet the EPA's mandated
requirements it is estimated that it will cost Consumers between approximately
$290 million and $500 million, in 1999 dollars. In both these cases the lower
estimate represents the capital expenditure level that would satisfactorily meet
the proposed emissions limits but would result in higher operating expense. The
higher estimate in the range includes expenditures that result in lower
operating costs while complying with the proposed emissions limit. Consumers
anticipates that these capital expenditures will be incurred between 1999 and
2004, or between 1999 and 2003 if the EPA's limits are imposed. Consumers may
need an equivalent amount of capital expenditures to comply with the new small
particulate standards some time after 2004 if those standards become effective.

                     CONSUMERS ENERGY COMPANY FINANCING III

GENERAL

     The trust is a statutory business trust created under Delaware law pursuant
to a declaration of trust and a certificate of trust, as filed with the
Secretary of State of the State of Delaware on October 12, 1999. The declaration
of trust will be amended and restated in its entirety, referred to as the
"declaration" or the "trust agreement," substantially in the form filed with the
SEC by Consumers and incorporated by reference into the registration statement
of which this prospectus supplement and the accompanying base prospectus form a
part. The declaration will be qualified as an indenture under the Trust
Indenture Act. Upon issuance of the preferred securities, the purchasers thereof
will own all of the preferred securities. Consumers will directly or indirectly
acquire common securities in a total liquidation amount equal to at least 3% of
the total capital of the trust and will own all of the issued and outstanding
common securities. The trust exists for the exclusive purposes of:

     - issuing the preferred securities and the common securities representing
       undivided beneficial interests in the assets of the trust;

                                      S-12
<PAGE>   15

     - investing the gross proceeds of the preferred securities and the common
       securities in the debentures; and

     - engaging in only those other activities necessary, appropriate,
       convenient or incidental thereto.

     The trust has a term of approximately 55 years, but may be terminated
earlier as provided in the declaration.

     Pursuant to the declaration, the number of trustees initially will be four.
Two of the trustees are employees or officers of Consumers. Bank of New York
will serve as property trustee under the declaration and as indenture trustee
for the purposes of the Trust Indenture Act. Bank of New York (Delaware) will
act as the Delaware trustee. The property trustee and the Delaware trustee may
at any time be removed or replaced by the holder of the common securities. For
purposes of compliance with the provisions of the Trust Indenture Act, Bank of
New York will also act as indenture trustee under the guarantee. See "The
Guarantees" in the base prospectus accompanying this prospectus supplement.

     The property trustee will hold title to the debentures for the benefit of
the trust and the holders of the preferred securities and common securities. So
long as the debentures are held by the trust, the property trustee will have the
power to exercise all rights, powers, and privileges of a holder of debentures
under the indenture. In addition, the property trustee will maintain exclusive
control of a segregated non-interest bearing bank account to hold all payments
made in respect of the debentures for the benefit of the holders of the
preferred securities and common securities. The property trustee will make
payments of distributions and payments on liquidation, redemption and otherwise
to the holders of the preferred securities and common securities out of funds
from the property account. The Bank of New York will hold the guarantee for the
benefit of the holders of the preferred securities. Consumers, as the direct or
indirect holder of all the common securities, will have the right to appoint,
remove or replace any trustee (subject to the limitations set forth in the
declaration) and to increase or decrease the number of trustees. Consumers will
pay all fees, expenses, debts and obligations (other than with respect to the
preferred securities and common securities) related to the trust and the
offering of the preferred securities.

     The rights of the holders of the preferred securities, including economic
rights, rights to information and voting rights are set forth in the
declaration, the Delaware Business Trust Act, the indenture and the Trust
Indenture Act. See "Certain Terms of the Preferred Securities" in this
prospectus supplement.

                              ACCOUNTING TREATMENT

     The financial statements of the trust will be reflected in Consumers'
consolidated financial statements, with the preferred securities shown as
"Company-obligated mandatorily redeemable preferred securities of subsidiaries
holding solely company subordinated notes." In a footnote to Consumers' audited
consolidated financial statements, there will be a statement that the trust is
wholly-owned by Consumers and that the sole asset of the trust is the debentures
(indicating the principal amount, interest rate and maturity date thereof).

                                USE OF PROCEEDS

     The proceeds from the sale of the preferred securities will be invested by
the trust in debentures of Consumers issued pursuant to the indenture described
herein. Consumers intends to use all of the net proceeds from the debentures to
repay short-term indebtedness. This short-term indebtedness was incurred on
April 1, 1999 for the redemption of Consumers' $2.08 Preferred Stock in an
aggregate amount of $200 million. As of October 7, 1999, the weighted average
interest rate of such short-term indebtedness was 6.04%.

                           DESCRIPTION OF SECURITIES

     This prospectus supplement and the accompanying base prospectus contain the
material terms and conditions for these securities, however, the summaries in
this prospectus supplement are not meant to be a complete description of the
preferred securities, the guarantee and the debentures. For more information,
refer to the trust agreement, the indenture and the guarantee. Forms of these
documents are filed as exhibits to the registration statement of which this
prospectus supplement and the accompanying base prospectus are a part. All terms
used in this prospectus supplement and the accompanying base prospectus that are
not defined in this prospectus supplement and the accompanying base prospectus
have the meanings given to them in the trust agreement, the indenture and the
guarantee.

CERTAIN TERMS OF THE PREFERRED SECURITIES

Distributions

     The preferred securities represent undivided beneficial interests in the
assets of the trust. The only assets of the trust will be the debentures.
Distributions on the preferred securities are cumulative and will accumulate
from                at the annual rate of      % of the $25 liquidation amount
of each preferred security. Distributions will be payable quarterly in arrears
on                ,                ,                and                of each
year, beginning             , 1999. Distributions not paid when

                                      S-15
<PAGE>   18

due will themselves accumulate distributions at the annual rate of      % (to
the extent permitted by law). When we refer to any payment of distributions, any
such additional distributions are included. The amount of distributions payable
for any full quarterly period will be computed on the basis of a 360-day year of
twelve 30-day months. The amount of distributions payable for any partial period
will be computed on the basis of the actual number of days elapsed in such
90-day quarterly period.

     If distributions are payable on a date that is not a business day (as
defined below), payment will be made on the next business day (and without any
interest or other payment in respect of such delay). However, if the next
business day is in the next calendar year, payment of distributions will be made
on the preceding business day. A "business day" means any day other than a
Saturday or a Sunday or a day on which banking institutions in New York, New
York are authorized or required by law or executive order to close.

Deferral of Distributions

     So long as no event of default has occurred and is continuing under the
debentures, Consumers may, on one or more occasions, defer interest payments on
the debentures to the trust for up to 20 consecutive quarterly periods. A
deferral of interest payments cannot extend beyond the stated maturity date of
the debentures on                . If Consumers defers interest payments on the
debentures, the trust will also defer quarterly distributions on the preferred
securities to you. During a deferral period, the amount of distributions due to
you would continue to accumulate and such deferred distributions will themselves
accumulate distributions at the rate stated above (to the extent permitted by
law).

     Once Consumers makes all deferred interest payments on the debentures, with
accrued interest, it may again defer interest payments on the debentures if no
event of default under the debentures has then occurred and is continuing.

     Consumers has no current intention of deferring interest payments on the
debentures. If Consumers defers interest payments on the debentures, Consumers
will be subject to certain restrictions relating to the payment of dividends on
or redemption of its capital stock and payments on its debt securities that rank
equal with or junior to the debentures. See "Certain Terms of the
Debentures -- Option to Extend Interest Payment Period" in this prospectus
supplement.

Payment of Distributions

     Distributions on the preferred securities will be payable to holders named
on the securities register of the trust on the relevant record date. As long as
the preferred securities are represented by a global security, the record date
for the payment of distributions will be one business day before the relevant
payment date. If the preferred securities are ever issued in certificated form,
the record date for the payment of distributions will be the                day
of the last month of each quarterly distribution period, even if that day is not
a business day.

     As long as the preferred securities are represented by a global security,
payments on the preferred securities will be made in immediately available funds
to DTC, the depositary for the preferred securities. If the preferred securities
are ever issued in certificated form, payment of distributions on the preferred
securities will be made by check mailed on or before the due date to the holders
thereof on the relevant record date.

                                      S-16
<PAGE>   19

Redemption

     Consumers will repay the debentures at maturity on                .
Consumers may, before their maturity, redeem:

     - all or some of the debentures on one or more occasions any time on or
       after                ; and

     - all but not some of the debentures before                , if certain
       changes in tax or investment company law occur or will occur within 90
       days (each of which is a "Special Event" more fully described below).

     When Consumers repays some or all of the debentures, either at maturity on
               or upon early redemption, the trust will use the cash it receives
upon the redemption of the debentures to redeem a like liquidation amount of the
preferred securities and, unless an event of default under the trust agreement
has occurred and is continuing, the common securities. The preferred securities
and common securities (if applicable) will be redeemed at a price equal to their
liquidation amount of $25 per security plus accumulated distributions, if any.
The redemption price for the debentures is 100% of their principal amount plus
accrued and unpaid interest to the date of redemption. See "Certain Terms of the
Debentures -- Redemption" in this prospectus supplement.

     If less than all the preferred securities and common securities are to be
redeemed in situations where common securities may be redeemed consistent with
the provisions described under "-- Subordination of Common Securities" in this
prospectus supplement, then the total liquidation amount of preferred securities
and common securities to be redeemed will be allocated proportionately based on
the liquidation amount of the preferred securities and the common securities.

Special Event Redemption

     Upon the occurrence of a Tax Event or an Investment Company Event as
defined below, Consumers may redeem all but not some of the debentures, within
90 days following the occurrence of the Special Event.

     "Tax Event" means that the trust has received an opinion of counsel
experienced in such matters to the effect that, as a result of any:

     - amendment to, or change (including any announced proposed change) in, the
       laws or regulations of the United States or any political subdivision or
       taxing authority affecting taxation; or

     - official or administrative pronouncement or action, or judicial decision,
       interpreting or applying such laws or regulations

where such change or amendment becomes effective, or such pronouncement, action
or decision is announced or occurs, on or after the date of this prospectus
supplement, there is more than an insubstantial risk that:

     - the trust is or, within 90 days of the date of such opinion, would be
       subject to United States federal income tax with respect to interest
       accrued or received on the debentures;

     - interest payable by Consumers on the debentures is not or, within 90 days
       of the date of such opinion, would not be deductible by Consumers in
       whole or in part for United States federal income tax purposes; or

     - the trust is or, within 90 days of the date of such opinion, would be
       subject to more than a minimal amount of other taxes, duties, assessments
       or other governmental charges.

     "Investment Company Event" means that the trust has received an opinion of
counsel experienced in such matters to the effect that, as a result of the
occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority, there is more than an insubstantial risk that
the trust is or will be considered an

                                      S-17
<PAGE>   20

"investment company" under the Investment Company Act of 1940 that is required
to be registered under this law, which change becomes effective on or after the
date of this prospectus supplement.

Redemption Procedures

     The trust will give you at least 30 days, but not more than 60 days,
written notice before any redemption of preferred securities. To the extent
funds are available for payment, the trust will irrevocably deposit with DTC
sufficient funds to pay the redemption amount for the preferred securities being
redeemed. The trust will also give DTC irrevocable instructions and authority to
pay the redemption amount in immediately available funds to the beneficial
owners of the global securities representing the preferred securities.
Distributions to be paid on or before the redemption date for any preferred
securities called for redemption will be payable to the holders on the record
dates for the related dates of distribution.

     Once notice of redemption is given and funds are irrevocably deposited,
distributions on the preferred securities will cease to accumulate immediately
prior to the close of business on the redemption date and all rights of the
holders of the preferred securities called for redemption will cease, except for
the right to receive the redemption amount (but without interest on such
redemption amount).

     If any redemption date is not a business day, then the redemption amount
will be payable on the next business day (and without any interest or other
payment in respect of any such delay).

     If payment of the redemption amount for any preferred securities called for
redemption is improperly withheld or refused and not paid either by the trust or
by Consumers, distributions on the preferred securities will continue to
accumulate at the applicable rate from the original redemption date scheduled to
the actual date of payment. In this case, the actual payment date will be
considered the redemption date for purposes of calculating the redemption
amount.

     In compliance with applicable law (including the United States federal
securities laws), Consumers or its affiliates may, at any time, purchase
outstanding preferred securities by tender, in the open market, or by private
agreement.

Events of Default

     An event of default under the indenture constitutes an event of default
under the declaration with respect to the preferred securities. However,
provided that pursuant to the declaration, the holder of the common securities
will be deemed to have waived any declaration event of default with respect to
the common securities until all declaration events of default with respect to
the preferred securities have been cured, waived or otherwise eliminated. Until
any declaration event of default with respect to the preferred securities has
been cured, waived or otherwise eliminated, the property trustee will be deemed
to be acting solely on behalf of the holders of the preferred securities and
only the holders of the preferred securities will have the right to direct the
property trustee with respect to certain matters under the declaration, and
therefore the indenture.

     Upon the occurrence of a declaration event of default, the indenture
trustee or the property trustee will have the right under the indenture to
declare the principal of and interest on the debentures to be immediately due
and payable.

Voting Rights

     Subject to the requirement of the property trustee obtaining a tax opinion
in certain circumstances set forth in the last sentence of this paragraph, the
holders of a majority in total liquidation amount of the preferred securities
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the property trustee, or direct the exercise of any
trust or power conferred upon

                                      S-18
<PAGE>   21

the property trustee under the declaration, including the right to direct the
property trustee, as holder of the debentures, to

     - exercise the remedies available under the indenture with respect to the
       debentures,

     - waive any past indenture event of default that is waivable under the
       indenture, or

     - exercise any right to rescind or annul a declaration that the principal
       of all the debentures shall be due and payable, or consent to any
       amendment, modification or termination of the indenture or the
       debentures, where such consent should be required.

     However, where a consent or action under the indenture would require the
consent or act of the holders of greater than a majority in principal amount of
debentures affected thereby, the property trustee may only give such consent or
take such action at the written direction of the holders of at least the
proportion in liquidation amount of the preferred securities which the relevant
super-majority represents of the total principal amount of the debentures
outstanding. The property trustee shall notify all holders of the preferred
securities of any notice of default received from the indenture trustee with
respect to the debentures. Except with respect to directing the time, method and
place of conducting a proceeding for a remedy, the property trustee shall not
take any of the actions described in the bullet points above unless the property
trustee has obtained an opinion of tax counsel to the effect that, as a result
of such action, the trust will not be classified as an association taxable as a
corporation for United States federal income tax purposes.

     In the event the consent of the property trustee, as the holder of the
debentures, is required under the indenture with respect to any amendment,
modification or termination of the indenture or the debentures, the property
trustee will request the direction of the holders of the preferred securities
with respect to such amendment, modification or termination. The property
trustee will then vote with respect to such amendment, modification or
termination as directed by a majority in liquidation amount of the preferred
securities voting together as a single class. However, where a consent under the
indenture would require the consent of a super-majority, the property trustee
may only give its consent at the direction of the holders of at least the
proportion in liquidation amount of the preferred securities which the relevant
super-majority represents of the total principal amount of the debentures
outstanding. The property trustee shall not take any such action in accordance
with the directions of the holders of the preferred securities unless the
property trustee has obtained an opinion of tax counsel to the effect that the
trust will not be classified as an association taxable as a corporation for
United States federal income tax purposes on account of such action.

Subordination of Common Securities

     Payment of distributions on, and the redemption and liquidation amount of,
the preferred securities and the common securities will be made proportionately
based on the total liquidation amounts of the preferred securities and the
common securities. However, if an event of default under the trust agreement has
occurred and is continuing, no payments may be made on the common securities
unless all unpaid amounts on the preferred securities have been provided for or
paid in full.

     If an event of default under the trust agreement has occurred and is
continuing, the common securities holder will be deemed to have waived any right
to take any action with respect to the event of default until the event of
default has been cured, waived or eliminated. Until any event of default has
been cured, waived or eliminated, the property trustee will act solely on behalf
of the holders of the preferred securities, and these holders will have the
right to direct the property trustee to act on their behalf.

Book-Entry-Only Issuance -- DTC

     The preferred securities will be represented by one or more global
securities that will be deposited with, or on behalf of, and registered in the
name of, DTC or its nominee. This means that the trust will not issue
certificates to you for the preferred securities. Each global security will be
issued to DTC which will keep a computerized record of its participants (for
example, a broker) whose clients have purchased
                                      S-19
<PAGE>   22

the preferred securities. Each participant will then keep a record of its
clients. Unless a global security is exchanged in whole or in part for a
certificated security, a global security may not be transferred. However, DTC,
its nominees and their successors may transfer a global security as a whole to
one another.

     Beneficial interests in a global security will be shown on, and transfers
of the global security will be made only through, records maintained by DTC and
its participants. DTC holds securities that its participants ("direct
participants") deposit with DTC. DTC also records the settlement among direct
participants of securities transactions, such as transfers and pledges, in
deposited securities through computerized records for direct participant's
accounts. This eliminates the need to exchange certificates. Direct participants
include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations.

     DTC's book-entry system is also used by other organizations such as
securities brokers and dealers, banks and trust companies that work through a
direct participant. The rules that apply to DTC and its participants are on file
with the Securities and Exchange Commission.

     DTC is owned by a number of its direct participants and by the New York
Stock Exchange, the American Stock Exchange and the National Association of
Securities Dealers.

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

     Purchases under the DTC System -- When you purchase preferred securities
through the DTC system, the purchases must be made by or through a direct
participant, who will receive credit for the preferred securities on DTC's
records. Because you actually own the preferred security, you are the beneficial
owner. Your ownership interest will be recorded only on the direct (or indirect)
participants' records. DTC has no knowledge of your individual ownership of the
preferred securities. DTC's records show only the identity of the direct
participants and the amount of the preferred securities held by or through them.
You will not receive a written confirmation of your purchase or sale or any
periodic account statement directly from DTC. You will receive these from your
direct (or indirect) participant. As a result, the direct (or indirect)
participants are responsible for keeping accurate account of the holdings of
their customers, like you.

     Payments under the DTC System -- The property trustee will wire payments on
the preferred securities to DTC's nominee. Consumers, the trust and the property
trustee will treat DTC's nominee as the owner and holder of each global security
representing preferred securities for all purposes. Accordingly, Consumers, the
trust and the property trustee will have no direct responsibility or liability
to pay amounts due on the global security to you or any other beneficial owners
in the global security.

     Any redemption notices will be sent by Consumers and the Trust directly to
DTC, who will in turn inform the direct participants, who will then contact you
as a beneficial owner. If less than all of the preferred securities are being
redeemed, DTC's practice is to choose by lot the amount of the interest of each
direct participant to be redeemed. The direct participant will then use an
appropriate method to allocate the redemption among its beneficial owners, like
you.

     It is DTC's current practice, upon receipt of any payment of distributions
or liquidation or redemption amount, to credit direct participants' accounts on
the payment date based on their holdings of beneficial interests in the global
securities as shown on DTC's records. In addition, it is DTC's current practice
to assign any consenting or voting rights to direct participants whose accounts
are credited with preferred securities on a record date, by using an omnibus
proxy. Payments by participants to owners of beneficial interests in the global
securities, and voting by participants, will be based on the customary practices
between the participants and owners of beneficial interests, as is the case with
securities held for the account of customers registered in "street name."
However, payments will be the responsibility of the participants and not of DTC,
the property trustee, Consumers or the trust.

     Year 2000 Issues -- DTC management is aware that some computer
applications, systems, and the like for processing data that are dependent upon
calendar dates, including dates before, on, and after January 1, 2000, may
encounter year 2000 problems. DTC has informed its participants and other
members of the financial community that it has developed and is implementing a
program so that its systems, as the same relate to the timely payment of
distributions (including principal and income payments) to securityholders,
book-entry deliveries, and settlement of trades within DTC, continue to function
appropriately. This program includes a technical assessment and a remediation
plan, each of which is complete. Additionally, DTC's plan includes a testing
phase, which is expected to be completed within appropriate time frames.

     DTC's ability to perform properly its services is also dependent upon other
parties, including issuers and their agents, as well as DTC's direct and
indirect participants and third party vendors from whom DTC licenses software
and hardware, and third party vendors on whom DTC relies for information or the
provision of services, including telecommunication and electrical utility
service providers, among others. DTC has informed the financial community that
it is contacting (and will continue to contact) third party vendors from whom
DTC acquires services to:

          (1) impress upon them the importance of such services being year 2000
     compliant; and

          (2) determine the extent of their efforts for year 2000 remediation
     (and, as appropriate, testing) of their services. In addition, DTC is in
     the process of developing such contingency plans as it deems appropriate.
     According to DTC, the foregoing information with respect to DTC has been
     provided to the financial community for informational purposes only and is
     not intended to serve as a representation, warranty or contract
     modification of any kind.

     Exchange of Global Securities -- Preferred securities represented by a
global security will be exchangeable for certificated securities with the same
terms in authorized denominations only if:

     - DTC is unwilling, unable or ineligible to continue as depositary and a
       successor depositary is not appointed by the trust within 90 days; or

     - Consumers decides to discontinue use of the system of book-entry transfer
       through DTC (or any successor depositary).

     If the book-entry-only system is discontinued, the property trustee will
keep the registration books for the preferred securities at its corporate office
and follow the practices and procedures discussed below.

Certificated Securities -- Registration and Transfer

     If the trust issues certificated securities, they will be registered in the
name of the securityholder. The preferred securities may be transferred or
exchanged, based on administrative procedures in the trust agreement, without
the payment of any service charge (other than any tax or other governmental
charge) by contacting the property trustee, Bank of New York, 101 Barclay
Street, 21W, New York, New York 10286, attention: Corporate Trust and Agency
Services -- Corporate Market Services.

CERTAIN TERMS OF THE DEBENTURES

     The debentures will be issued as a series pursuant to a supplemental
indenture or a resolution of Consumers' board of directors or a committee
thereof as provided for in the indenture.

Subordination

     The debentures are unsecured and are junior in right of payment to all of
Consumers' "senior indebtedness". Consumers may not make any payments of
principal (including redemption payments) or interest on the debentures if it
defaults on a payment on its senior indebtedness. Also, payments on the
debentures may be blocked for up to 180 days in the event of certain non-payment
defaults by Consumers on its senior indebtedness. See "Subordinated Debentures"
in the accompanying base prospectus for more detailed information.
                                      S-21
<PAGE>   24

     On any distribution of assets of Consumers to creditors upon any
liquidation, dissolution, winding-up, reorganization, assignment for the benefit
of creditors, marshalling of assets or liabilities or any bankruptcy, insolvency
or similar proceedings, all principal, premium, if any, and interest due or to
become due on all senior indebtedness must be paid in full before the holders of
the debentures are entitled to receive or retain any payment.

     Neither the debentures nor the guarantee will limit the ability of
Consumers and its subsidiaries to incur additional indebtedness, including
indebtedness that ranks senior in priority of payment to the debentures and the
guarantee. At June 30, 1999, as if on that date Consumers and the trust had
issued and sold the preferred securities and the debentures and applied the
estimated net proceeds thereof as described in this prospectus supplement, the
total amount of Consumers' senior indebtedness would have been approximately
$       . See "Capitalization" and "Use of Proceeds" in this prospectus
supplement.

Interest Rate and Maturity

     The debentures will mature on           and will bear interest, accruing
from                , at the annual rate of           % of their principal
amount, payable quarterly in arrears on           ,           ,           and
          of each year, beginning           . Interest payments not paid when
due will themselves accrue additional interest at the annual rate of   % (to the
extent permitted by law). When we refer to any payment of interest, interest
includes such additional interest and any additional amounts, as defined below.
The interest payment provisions for the debentures correspond to the
distribution provisions of the preferred securities. The debentures do not have
a sinking fund. This means that Consumers is not required to make any principal
payments prior to maturity.

Additional Sums

     If the trust is required to pay any taxes, duties, assessments or
governmental charges of whatever nature (other than withholding taxes) imposed
by the United States, or any other taxing authority, then Consumers will be
required to pay additional amounts on the debentures so that after the trust
pays any taxes, the trust will be in the same position it would have been if it
did not have to pay such taxes.

Redemption

     Consumers may redeem, before their maturity:

     - all or some of the debentures on one or more occasions any time on or
       after                ; or

     - all but not some of the debentures before                , upon the
       occurrence of a Special Event.

     If Consumers decides to redeem debentures in these circumstances, the
redemption price of each debenture redeemed will be equal to 100% of the
principal amount of such debenture plus accrued and unpaid interest on such
debenture to the date of redemption.

Distribution of Debentures

     If the property trustee distributes the debentures to the preferred
securities holders and common securities holder upon the dissolution and
liquidation of the trust, the debentures will be issued in denominations of $25
principal amount and integral multiples thereof. Consumers anticipates that the
debentures would be distributed in the form of one or more global securities and
DTC, or any successor depositary for the preferred securities, would act as
depositary for the debentures. The depositary arrangements for the debentures
would be substantially similar to those in effect for the preferred securities.

     For a description of DTC and the terms of the depositary arrangements
relating to payments, transfers, voting rights, redemption, other notices and
other matters, see "Certain Terms of the Preferred Securities -- Book-Entry-Only
Issuance -- DTC" in this prospectus supplement.

                                      S-22
<PAGE>   25

Option to Extend Interest Payment Period

     Consumers may, on one or more occasions, defer interest payments on the
debentures for up to 20 consecutive quarterly periods, if no event of default
has occurred and is continuing with respect to the debentures. A deferral of
interest payments cannot extend beyond the stated maturity date of the
debentures. No interest will be due and payable on the debentures until the end
of the deferral period unless the debentures are redeemed prior to such time.

     Consumers may pay at any time all or any portion of the interest accrued to
that point during a deferral period. At the end of the deferral period or at a
redemption or maturity date, Consumers will be obligated to pay all accrued and
unpaid interest.

     Once Consumers makes all interest payments on the debentures, with accrued
interest, it may again defer interest payments on the debentures if no event of
default under the debentures has then occurred and is continuing.

     During any deferral period and subject to certain exceptions, Consumers
will not be permitted to:

     - declare or pay any dividends or distributions or redeem, purchase,
       acquire or make a liquidation payment with respect to, any shares of its
       capital stock;

     - make any payment of principal, interest or premium, if any, on or repay
       or repurchase or redeem any debt securities issued by Consumers which
       rank equal with or junior to the debentures; or

     - make any guarantee payments with respect to any guarantee by Consumers of
       the debt securities of Consumers if such guarantee ranks equal with or
       junior to the debentures.

     Because the debentures to be issued to the trust will rank equal with all
other series of junior subordinated debt securities of Consumers initially
issued to the other trusts referred to in the accompanying base prospectus or to
certain other trusts, partnerships or other entities affiliated with Consumers,
during an interest deferral period, Consumers will not be permitted to make
payments on such other series of junior subordinated debt securities. Likewise,
if Consumers defers interest payments on any other of such series of junior
subordinated debt securities, it is not expected that Consumers will be
permitted to make payments on the debentures.

     The restrictions described in the bullet points above will also apply if
there occurs and is continuing a default or event of default under the indenture
of which Consumers has actual knowledge and in respect of which Consumers has
not taken reasonable steps to cure or if Consumers defaults on its obligations
under the guarantee.

     Consumers will give the trust, the regular trustees, the property trustee
and the indenture trustee notice if it decides to defer interest payments on the
debentures. As long as the debentures are held by the trust, Consumers will give
that notice at least one business day before the earlier of:

     - the next date distributions on the preferred securities are payable; or

     - the date the trust is required to give notice to the New York Stock
       Exchange (or any other applicable self-regulatory organization) or to
       holders of the preferred securities of the record date or the date
       distributions are payable.

     There is no limitation on the number of times that Consumers may elect to
begin an extension period. The regular trustees will give notice to the property
trustee and the holders of preferred securities if Consumers decides to defer
interest payments on the debentures.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

GENERAL

     In this section, we summarize certain of the material United States federal
income tax consequences of purchasing, holding and selling the preferred
securities. Except where we state otherwise, this summary deals only with
preferred securities held as capital assets (as defined in the Internal Revenue
Code of 1986) by a U.S. Holder (as defined below) who purchases the preferred
securities at their original offering price when the trust originally issues
them.

     We do not address all of the tax consequences that may be relevant to a
U.S. Holder. We also do not address, except as stated below, any of the tax
consequences to holders that may be subject to special tax treatment including
banks, thrift institutions, real estate investment trusts, personal holding
companies, tax-exempt organizations, regulated investment companies, insurance
companies, and brokers and dealers in securities or currencies. Further, we do
not address:

     - the United States federal income tax consequences to shareholders in, or
       partners or beneficiaries of, an entity that is a holder of the preferred
       securities;

     - the United States federal estate and gift or alternative minimum tax
       consequences of the purchase, ownership or sale of the preferred
       securities;

     - persons who hold the preferred securities in a "straddle" or as part of a
       "hedging," "conversion" or "constructive sale" transaction or whose
       "functional currency" is not the United States dollar; or

     - any state, local or foreign tax consequences of the purchase, ownership
       and sale of preferred securities.

     Accordingly, you should consult your tax advisor regarding the tax
consequences of purchasing, owning and selling the preferred securities in light
of your circumstances.

     A "U.S. Holder" is a preferred securities holder who or which is:

     - a citizen or resident of the United States;

     - a corporation or partnership created or organized in or under the laws of
       the United States, any state thereof or the District of Columbia (unless,
       in the case of a partnership, Treasury regulations provide otherwise);

     - an estate if its income is subject to United States federal income
       taxation regardless of its source; or

     - a trust if (1) a United States court can exercise primary supervision
       over its administration and (2) one or more United States persons have
       the authority to control all of its substantial decisions.

     This summary is based on the Internal Revenue Code, Treasury regulations
(proposed and final) issued under the Internal Revenue Code, and administrative
and judicial interpretations thereof, all as they currently exist as of the date
of this prospectus supplement. These income tax laws and regulations, however,
may change at any time, possibly on a retroactive basis. Any such changes may
affect this summary.

CLASSIFICATION OF THE DEBENTURES

     Consumers intends to take the position that the debentures will be
classified for United States federal income tax purposes as indebtedness of
Consumers under current law, and, by acceptance of a preferred security, each
holder covenants to treat the debentures as indebtedness and the preferred
securities as evidence of an indirect beneficial ownership interest in the
debentures. No assurance can be given, however, that such position of Consumers
will not be challenged by the Internal Revenue Service or, if challenged, that
such a challenge would not be successful. The remainder of this discussion
assumes that

                                      S-24
<PAGE>   27

the debentures will be classified as indebtedness of Consumers for United States
federal income tax purposes.

CLASSIFICATION OF THE TRUST

     In connection with the issuance of the preferred securities, tax counsel
for Consumers will render a legal opinion generally to the effect that, under
current law and assuming full compliance with the terms of the trust agreement,
the indenture, and certain other documents, and based on certain facts and
assumptions described in the opinion, the Trust will be classified for United
States federal income tax purposes as a grantor trust and will not be subject to
tax as a corporation. Accordingly, for United States federal income tax
purposes, you will generally be treated as the owner of an undivided interest in
the assets of the Trust, including the debentures. You will be required to
include in ordinary income for United States federal income tax purposes your
allocable share of interest (or OID, if any) paid or accrued on the debentures.

INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT

     Under the Treasury regulations relating to OID, a debt instrument will be
deemed to be issued with OID if there is more than a "remote" contingency that
periodic stated interest payments due on the instrument will not be timely paid.
Because the exercise by Consumers of its option to defer payments of stated
interest on the debentures would prevent Consumers from:

     - declaring dividends, or engaging in certain other capital transactions,
       with respect to its capital stock, or

     - making any payment on any debt securities issued by Consumers which rank
       equal with or junior to the debentures, Consumers believes that the
       likelihood of its exercising the option is "remote" within the meaning of
       the Treasury regulations.

     As a result, Consumers intends to take the position that the debentures
will not be deemed to be issued with OID. Based on this position, stated
interest payments on the debentures will be includible in your ordinary income
at the time that such payments are received or accrued in accordance with your
regular method of accounting. Because the Internal Revenue Service has not yet
addressed the Treasury regulations in any published rulings or other
interpretations, it is possible that the Internal Revenue Service could take a
position contrary to the position taken by Consumers. In that event, the
Internal Revenue Service may, for example, require you to include interest on
the debentures in your taxable income as it accrues rather than when you receive
payment even though you use the cash method of accounting for federal income tax
purposes.

EXERCISE OF DEFERRAL OPTIONS

     Under Treasury regulations, if Consumers were to exercise its option to
defer the payment of interest on the debentures, the debentures would be treated
as redeemed and reissued for OID purposes and the sum of the remaining interest
payments on the debentures would be treated as OID, which you would be required
to accrue and include in taxable income on an economic accrual basis (regardless
of your method of accounting for income tax purposes) over the remaining term of
the debentures (including any period of interest deferral), without regard to
the timing of payments under the debentures. The amount of interest income
includible in your taxable income would be determined on the basis of a constant
yield method over the remaining term of the debentures and the actual receipt of
future payments of stated interest on the debentures would no longer be
separately reported as taxable income. The total amount of OID that would accrue
during the deferred interest payment period would be approximately equal to the
amount of the cash payment due at the end of such period. Any OID included in
income would increase your adjusted tax basis in your preferred securities, and
your actual receipt of cash interest payments would reduce your basis in the
preferred securities.

                                      S-25
<PAGE>   28

CORPORATE U.S. HOLDERS

     Corporate U.S. Holders of the preferred securities will not be entitled to
a dividends-received deduction for any income from the preferred securities.

SALES OF PREFERRED SECURITIES

     If you sell your preferred securities, you will recognize gain or loss in
an amount equal to the difference between your adjusted tax basis in the
preferred securities and the amount realized from the sale (generally, your
selling price less any amount received in respect of accrued but unpaid interest
not previously included in your income). Your adjusted tax basis in the
preferred securities generally will equal:

     - the initial purchase price that you paid for the preferred securities
       plus

     - any accrued and unpaid distributions that you were required to treat as
       OID less any cash distributions received in respect of accrued OID.

     Gain or loss on the sale of preferred securities generally will be capital
gain or loss.

     The preferred securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest (or OID if the debentures are
treated as having been issued or reissued with OID) relating to the underlying
debentures. If you dispose of your preferred securities, you will be required to
include in ordinary income for United States federal income tax purposes any
portion of the amount realized that is attributable to accrued but unpaid,
interest (including OID, if any) through the date of sale. This income inclusion
will increase your adjusted tax basis in the preferred securities but may not be
reflected in the sale price. To the extent the sale price is less than your
adjusted tax basis, you will recognize a capital loss. Subject to certain
limited exceptions, capital losses cannot be applied to offset ordinary income
for United States federal income tax purposes.

RECEIPT OF DEBENTURES OR CASH UPON LIQUIDATION OF THE TRUST

     If Consumers dissolves the trust and causes the trust to distribute the
debentures on a proportionate basis to you, you will not be subject to tax.
Rather, you would have an adjusted tax basis in the debentures received in the
liquidation equal to the adjusted tax basis in your preferred securities
surrendered for the debentures. Your holding period for the debentures would
include the period during which you had held the preferred securities. If,
however, the trust is classified, for United States federal income tax purposes,
as an association that is subject to tax as a corporation at the time of the
liquidation, the distribution of the debentures would constitute a taxable event
to you and you would acquire a new holding period in the debentures received.

     If the debentures are redeemed for cash and the proceeds of the redemption
are distributed to you in redemption of your preferred securities, the
redemption would be treated as a sale of the preferred securities, in which gain
or loss would be recognized, as described immediately above.

INFORMATION REPORTING AND BACK-UP WITHHOLDING

     Generally, income on the preferred securities will be reported to you on an
Internal Revenue Service Form 1099, which should be mailed to you by January 31
following each calendar year. If you fail to supply your correct taxpayer
identification number or under-report your tax liability, the Internal Revenue
Service may require the property trustee or its agent to withhold federal income
tax at the rate of 31% from each interest payment. You will be permitted to
credit any withheld tax against your federal income tax liability.

                              ERISA CONSIDERATIONS

     Each fiduciary of a pension, profit-sharing or other employee benefit plan
subject to Title I of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA") (a "Plan"), should consider the fiduciary standards of ERISA
in the context of the Plan's particular circumstances before authorizing an
investment in the preferred securities with assets of the Plan. Accordingly,
among other factors, the fiduciary should consider whether the investment would
satisfy the prudence and diversification requirements of ERISA and would be
consistent with the documents and instruments governing the Plan.

     Section 406 of ERISA and Section 4975 of the Code prohibit Plans, as well
as individual retirement accounts and Keogh plans subject to Section 4975 of the
Code (also "Plans"), from engaging in certain transactions involving "plan
assets" with persons who are "parties in interest" under ERISA or "disqualified
persons" under the Code ("Parties in Interest") with respect to such Plan. A
violation of these "prohibited transaction" rules may result in an excise tax or
other liabilities under ERISA and/or Section 4975 of the Code for such persons,
unless exemptive relief is available under an applicable statutory or
administrative exemption.

     Employee benefit plans that are governmental plans (as defined in Section
3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and
foreign plans (as described in Section 4(b)(4) of ERISA) are not subject to the
requirements of ERISA or Section 4975 of the Code; however, such plans may be
subject to federal, state or local laws or regulations which affect their
ability to invest in the preferred securities. Any fiduciary of such a
governmental, church or foreign plan considering an investment in the preferred
securities should determine the need for, and, if necessary, the availability
of, any exemptive relief under such laws or regulations.

     Under a regulation (the "Plan Assets Regulation") issued by the U.S.
Department of Labor (the "DOL"), the assets of the trust may be deemed to be
"plan assets" of a Plan for purposes of ERISA and Section 4975 of the Code if
"plan assets" of the Plan were used to acquire an equity interest in the trust
and no exception were applicable under the Plan Assets Regulation. An "equity
interest" is defined under the Plan Assets Regulation as any interest in an
entity other than an instrument which is treated as indebtedness under
applicable local law and which has no substantial equity features and
specifically includes a beneficial interest in a trust.

     Pursuant to an exception contained in the Plan Assets Regulation, the
assets of the trust would not be deemed to be "plan assets" of investing Plans
if, immediately after the most recent acquisition of any equity interest in the
trust, less than 25% of the value of each class of equity interests in the trust
were held by Plans, other employee benefit plans not subject to ERISA or Section
4975 of the Code (such as governmental, church and foreign plans), and entities
holding assets deemed to be "plan assets" of any Plan (collectively, "Benefit
Plan Investors"), or if the preferred securities were "publicly-offered
securities" for purposes of the Plan Assets Regulation. No assurance can be
given that the value of the preferred securities held by Benefit Plan Investors
will be less than 25% of the total value of such preferred securities at the
completion of the initial offering or thereafter, and no monitoring or other
measures will be taken with respect to the satisfaction of the conditions of
this exception. In addition, no assurance can be given that the preferred
securities would be considered to be "publicly-offered securities" under the
Plan Assets Regulation. All of the common securities will be purchased and held
by Consumers.

     Certain transactions involving the trust could be deemed to constitute
direct or indirect prohibited transactions under ERISA and Section 4975 of the
Code with respect to a Plan if the preferred securities were acquired with "plan
assets" of such Plan and the assets of the trust were deemed to be "plan assets"
of Plans investing in the trust. For example, if Consumers were a Party in
Interest with respect to a Plan (either directly or by reason of ownership of
its subsidiaries), extensions of credit between Consumers and the trust (as
represented by the debentures and the guarantee) would likely be prohibited by
Section 406(a)(1)(B) of ERISA and Section 4975(c)(1)(B) of the Code, unless
exemptive relief were available under an applicable administrative exemption
(see below). In addition, if Consumers were considered to be a fiduciary with
respect to the trust as a result of certain powers it holds (such as the powers

including the optional redemption or acceleration of the debentures, could be
considered to be prohibited transactions under Section 406(b) of ERISA and
Section 4975(c)(1)(E) of the Code. In order to avoid such prohibited
transactions, each investing plan, by purchasing preferred securities, will be
deemed to have directed the trust to invest in the debentures and to have
appointed the property trustee.

     The DOL has issued five prohibited transaction class exemptions ("PTCEs")
that may provide exemptive relief if required for direct or indirect prohibited
transactions that may arise from the purchase or holding of the preferred
securities if assets of the trust were deemed to be "plan assets" of Plans
investing in the trust as described above. Those class exemptions are PTCE 96-23
(for certain transactions effected on behalf of a Plan by an in-house asset
manager), PTCE 95-60 (for certain transactions involving insurance company
general accounts), PTCE 91-38 (for certain transactions involving bank
collective investment funds), PTCE 90-1 (for certain transactions involving
insurance company separate pooled accounts), and PTCE 84-14 (for certain
transactions effected on behalf of a Plan by an independent qualified
professional asset manager).

     Because the preferred securities may be deemed to be equity interests in
the trust for purposes of ERISA and Section 4975 of the Code, the preferred
securities may not be purchased and should not be held by any Plan, any entity
whose underlying assets include "plan assets" by reason of any Plan's investment
in the entity (a "Plan Asset Entity") or any person investing "plan assets" of
any Plan, unless such purchaser or holder is eligible for the exemptive relief
available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or another applicable
exemption. Any purchaser or holder of the preferred securities or any interest
therein will be deemed to have represented by its purchase and holding thereof
that it either (a) is not a Plan or a Plan Asset Entity and is not purchasing
such securities on behalf of or with "plan assets" of any Plan, or (b) is
eligible for the exemptive relief available under PTCE 96-23, 95-60, 91-38, 90-1
or 84-14 or another applicable exemption with respect to such purchase or
holding.

     Due to the complexity of these rules and the penalties that may be imposed
upon persons involved in non-exempt prohibited transactions, it is particularly
important that fiduciaries or other persons considering purchasing the preferred
securities on behalf of or with "plan assets" of any Plan consult with their
counsel regarding the potential consequences if the assets of the trust were
deemed to be "plan assets" and the availability of exemptive relief under PTCE
96-23, 95-60, 91-38, 90-1 or 84-14 or any other applicable exemption.

     The discussion herein of ERISA is general in nature and is not intended to
be complete. Any fiduciary of a plan, governmental plan, church plan or a
foreign plan considering an investment in the preferred securities should
consult with its legal advisors regarding the consequences and advisability of
such investment.

     Insurance companies considering an investment in the preferred securities
should note that the Small Business Job Protection Act of 1996 added new Section
401(c) of ERISA relating to the status of the assets of insurance company
general accounts under ERISA and Section 4975 of the Code. Pursuant to Section
401(c), the DOL issued proposed regulations (the "Proposed General Account
Regulations") in December, 1997 with respect to insurance policies that are
supported by an insurer's general account. The Proposed General Account
Regulations are intended to provide guidance on which assets held by the insurer
constitute "plan assets" of an ERISA Plan for purposes of the fiduciary
responsibility provisions of ERISA and Section 4975 of the Code.

                                  UNDERWRITING

GENERAL

     Subject to the terms and conditions of an underwriting agreement, the trust
has agreed to sell to each of the underwriters named below, and each of the
underwriters, for whom Merrill Lynch, Pierce, Fenner & Smith Incorporated, A.G.
Edwards & Sons, Inc., First of Michigan Division of Fahnestock & Co. Inc.,
Morgan Stanley & Co. Incorporated, Prudential Securities Incorporated, and
Raymond James & Associates, Inc., are acting as the representatives, has
severally agreed to purchase from the trust, the number of preferred securities
set forth opposite its name below:

                        -----------                           --------------------
<S>                                                           <C>

Prudential Securities Incorporated..........................
Raymond James & Associates, Inc.............................
             Total..........................................
</TABLE>

     In the underwriting agreement the several underwriters have agreed, subject
to the terms and conditions set forth in that agreement, to purchase all of the
preferred securities offered hereby if any of the preferred securities are
purchased. In the event of default by an underwriter, the underwriting agreement
provides that, in certain circumstances, the purchase commitments of the
non-defaulting underwriters may be increased or the underwriting agreement may
be terminated.

     Consumers and the trust have agreed with the underwriters to indemnify them
against certain civil liabilities, including liabilities under the Securities
Act of 1933, or to contribute with respect to payments which the underwriters
may be required to make.

     Certain of the underwriters and their affiliates have in the past and may
in the future engage in transactions with, or perform services for, Consumers in
the ordinary course of their businesses.

     Consumers will pay all expenses, estimated to be approximately
$          associated with the offer and sale of the preferred securities.

COMMISSIONS AND DISCOUNTS

     The underwriters will offer the preferred securities directly to the public
initially at $25 per preferred security. The underwriters may also offer the
preferred securities to certain dealers at the above-mentioned offering price
less a concession of $.               per preferred security. The underwriters
may allow, and such dealers may reallow, a discount not in excess of
$.               per preferred security to certain dealers. After the initial
public offering, the public offering price, concession and discount may be
changed.

     Because the proceeds from the sale of the preferred securities and the
common securities will be used to purchase the debentures, Consumers has agreed
to pay to the underwriters an underwriting commission of $.       per preferred
security (or a total of $               ).

NEW YORK STOCK EXCHANGE LISTING

     Before this offering, there was no established public trading market for
the preferred securities. We plan to list the preferred securities on the New
York Stock Exchange under the symbol "       ." Trading of the preferred
securities on the New York Stock Exchange is expected to begin within 30 days of
the issuance of the preferred securities. In order to meet all of the
requirements for listing the preferred

                                      S-29
<PAGE>   32

securities on the New York Stock Exchange, the underwriters have agreed to sell
the preferred securities to a minimum of 400 beneficial holders. The
representatives have advised Consumers that they intend to make a market in the
preferred securities prior to the commencement of trading on the New York Stock
Exchange. However, the representatives are not obligated to do so and may
discontinue market making at any time without notice. We cannot give any
assurance that a liquid trading market for the preferred securities will be
available.

NO SALES OF SIMILAR SECURITIES

     Consumers and the trust have agreed that, during a period of    days from
the date of the pricing of the preferred securities, they will not offer, sell,
contract to sell, or otherwise dispose of any preferred securities, any other
beneficial interests of the trust, or any securities of Consumers, that are
substantially similar to the preferred securities, including the guarantee, and
including but not limited to any securities that are convertible into or
exchangeable for, or that represent the right to receive preferred securities or
any such substantially similar securities of either the trust or Consumers
(except the debentures and the preferred securities offered by this prospectus
supplement), without the prior consent of the representatives.

PRICE STABILIZATION AND SHORT POSITIONS

     In connection with the sale of the preferred securities, SEC rules permit
the underwriters to engage in transactions that stabilize the price of the
preferred securities. These transactions may include purchases for the purpose
of fixing or maintaining the price of the preferred securities.

     The underwriters may create a short position in the preferred securities in
connection with this offering. That means they may sell a larger number of the
preferred securities than is shown on the cover page of this prospectus
supplement. If they create a short position, the underwriters may purchase
preferred securities in the open market to reduce the short position.

     If the underwriters purchase the preferred securities to stabilize the
price or to reduce their short position, the price of the preferred securities
could be higher than it might be if they had not made such purchases. The
underwriters make no representation or prediction about any effect that the
purchases may have on the price of the preferred securities.

     The underwriters may suspend any of these activities at any time.

PENALTY BIDS

     The representatives also may impose a penalty bid on certain underwriters
and selling group members. This means that, if the representatives purchase
preferred securities in the open market to reduce the underwriters' short
position or to stabilize the price of the preferred securities, they may reclaim
the amount of the selling concession from the underwriters and selling group
members who sold those preferred securities as part of this offering.

securities, the enforceability of the trust agreement and the creation of the
trust will be passed upon on behalf of the trust by Richards, Layton & Finger,
P.A., Wilmington, Delaware, special Delaware counsel to the trust. The validity

1999, an attorney currently employed by Skadden, Arps, Slate, Meagher & Flom
LLP, and formerly employed by CMS Energy Corporation, owned approximately 50,326
shares of CMS Energy Common Stock, 2,000 shares of Class G Common Stock, 10

                                    EXPERTS

     The consolidated financial statements and schedule of Consumers as of
December 31, 1998 and 1997, and for each of the three years in the period ended
December 31, 1998 incorporated by reference in this prospectus supplement and
the accompanying base prospectus, have been audited by Arthur Andersen LLP,
independent public accountants, as indicated in their reports with respect
thereto, and are included herein in reliance upon the authority of said firm as
experts in accounting and auditing in giving said reports.

     With respect to the unaudited interim consolidated financial information
for the periods ended March 31 and June 30, 1999 and 1998, Arthur Andersen LLP
has applied limited procedures in accordance with professional standards for a
review of that information. However, their separate reports thereon state that
they did not audit and they did not express an opinion on that interim
consolidated financial information. Accordingly, the degree of reliance on their
reports on that information should be restricted in light of the limited nature
of the review procedures applied. In addition, the accountants are not subject
to the liability provisions of Section 11 of the Securities Act, for their
reports on the unaudited interim consolidated financial information because
these reports are not "reports" or a part of the registration statement prepared
or certified by the accountants within the meaning of Sections 7 and 11 of the
Securities Act.

     Future consolidated financial statements of Consumers and the reports
thereon of Arthur Andersen LLP also will be incorporated by reference in this
base prospectus in reliance upon the authority of that firm as experts in giving
those reports to the extent that said firm has audited said consolidated
financial statements and consented to the use of their reports thereon.

     - Consumers will guarantee the trust preferred securities such that the
       holders of the trust preferred securities, with respect to the payment of
       distributions and amounts upon liquidation, dissolution and winding-up,
       are at least in the same position with regard to the assets of Consumers

       trusts are wholly-owned by Consumers, that the sole assets of the trusts
       are the senior notes or the subordinated debentures of Consumers having a
       specified total principal amount, and, considered together, the back-up
       undertakings, including the guarantees, constitute a full and
       unconditional guarantee by Consumers of the trusts' obligations under the
       trust preferred securities issued by the trusts.

     - each trust is a newly created special purpose entity, has no operating
       history, no independent operations and is not engaged in, and does not
       propose to engage in, any activity other than as described under

                            CONSUMERS ENERGY COMPANY

     Consumers, formed in Michigan in 1968, is the successor to a corporation
organized in Maine in 1910 that did business in Michigan from 1915 to 1968.
Consumers was named Consumers Power Company from 1910 to the first quarter of
1997, when Consumers changed its name to Consumers Energy Company. Consumers is
the principal subsidiary of CMS Energy Corporation, a Michigan corporation.

     Consumers is a public utility that provides natural gas and electricity to
almost six million of the nine and one-half million residents in Michigan's
Lower Peninsula. Consumers' electric operations include the generation,
purchase, transmission and distribution of electricity. It provides electric
services in 61 of the 68 counties of Michigan's Lower Peninsula. Consumers' gas
utility operation purchases, transports, stores and distributes natural gas. It
renders gas sales and delivery service in 54 of the 68 counties in Michigan's
Lower Peninsula. At year end 1998, Consumers provided service to 1.6 million
electric customers and 1.5 million gas customers.

     Consumers' consolidated operating revenue in 1998 was $3.7 billion. Of
Consumers' operating revenue, 70% was generated from its electric utility
business, 29% from its gas utility business, and 1% from its non-utility
business.

     Consumers' electric generating system consists of five fossil-fueled plant
sites, one nuclear plant, one pumped storage hydroelectric facility, seven gas
combustion turbine plants and 13 hydroelectric plants. Consumers' owned and
operated a total of 6,190 megawatts ("MW") of electric generating capacity in
1998. In 1998, Consumers purchased 2,545 MW of net capacity, which amounted to
34% of Consumers' total system requirements, from other power producers, the
largest being a natural gas-fueled cogeneration facility ("MCV Facility")
operated by the Midland Cogeneration Venture Limited Partnership ("MCV
Partnership"). Consumers, through wholly-owned subsidiaries, owns a 49%
ownership interest in the MCV Partnership and lessor interest in the MCV
Facility. Total electric sales in 1998 were 40 billion kilowatt hours ("kWh"), a
6% increase over 1997 levels. Consumers' electric operating revenue in 1998 was
$2.6 billion, an increase of 3.6% from 1997.

     In 1998, Consumers' gas distribution and transmission system consisted of
23,392 miles of distribution mains and 1,165 miles of transmission lines
throughout the Lower Peninsula of Michigan. At December 31, 1998, Consumers
owned and operated six compressor stations with a total of 115,400 installed
horsepower. Consumers' gas operation is seasonal to the extent that peak demand
occurs in winter due to colder temperatures. Total deliveries of natural gas
sold by Consumers and from other sellers over Consumers' pipeline and
distribution network to ultimate customers, including the MCV Partnership,
totaled 360 billion cubic feet in 1998. Consumers' gas operating revenue in 1998
was $1.1 billion, a decrease of 12.7% from 1997.

Storage Company, a subsidiary of Consumers, relating, among other things, to the
construction of facilities and to service provided and rates charged by Michigan
Gas Storage. Some of Consumers' gas business is also subject to regulation of
FERC, including a blanket transportation tariff pursuant to which Consumers can

                        CONSUMERS ENERGY COMPANY TRUSTS

     Consumers Energy Company Financing III and Consumers Energy Company
Financing IV are statutory business trusts created under the Delaware Business
Trust Act by way of:

     - trust agreements executed by Consumers, as sponsor, and the trustees of
       the trusts and

     - the filing of certificates of trust with the Secretary of State of the
       State of Delaware.

     At the time of public issuance of the trust preferred securities, each
trust agreement will be amended and restated in its entirety and will be
qualified as an indenture under the Trust Indenture Act of 1939, as amended.
Consumers will directly or indirectly acquire common securities of each trust in
a total liquidation amount equal to approximately 3% of the total capital of the
trust. Each trust exists for the exclusive purposes of:

     - issuing the trust preferred securities and common securities representing
       undivided beneficial interests in the assets of the trust;

     - investing the gross proceeds of the common securities and the trust
       preferred securities in the senior notes or subordinated debentures; and

     - engaging in only those other activities necessary or incidental thereto.

     Each trust has a term of approximately 55 years, but may terminate earlier
as provided in the amended and restated trust agreement.

     The proceeds from the offering of the trust preferred securities and the
sale of the common securities may be used by each trust to purchase from
Consumers senior notes or subordinated debentures in a total principal amount
equal to the total liquidation preference of the common securities and the trust
preferred securities. The Consumers notes or debentures would bear interest at
an annual rate equal to the annual distribution rate of the common securities
and the trust preferred securities and would have certain
                                        4
<PAGE>   38

redemption terms which correspond to the redemption terms for the common
securities and the trust preferred securities. The senior notes will rank on an
equal basis with all other unsecured debt of Consumers except subordinated debt.
The subordinated debentures will rank subordinate in right of payment to all of
Consumers' senior indebtedness (as defined in this prospectus). Distributions on
the common securities and the trust preferred securities may not be made unless
each trust receives corresponding interest payments on the senior notes or the
subordinated debentures from Consumers. Consumers will irrevocably guarantee, on
a senior or subordinated basis, as applicable, and to the extent set forth in
the guarantee, with respect to each of the common securities and the trust
preferred securities, the payment of distributions, the redemption price,
including all accrued or deferred and unpaid distributions, and payment on
liquidation, but only to the extent of funds on hand. Each guarantee will be
unsecured and will be either equal to or subordinate to, as applicable, all
senior indebtedness, of Consumers. Upon the occurrence of certain events
(subject to the conditions to be described in an accompanying prospectus
supplement) each trust may be liquidated and the holders of the common
securities and the trust preferred securities could receive senior notes or
subordinated debentures in lieu of any liquidating cash distribution.

     Pursuant to the amended and restated trust agreements, the number of
trustees of each trust will initially be four. Two of the trustees will be
persons who are employees or officers of or who are affiliated with Consumers
and will be referred to as the regular trustees. The third trustee will be a
financial institution that is unaffiliated with Consumers, which trustee will
serve as property trustee under the applicable amended and restated trust
agreement and as indenture trustee for the purposes of compliance with the
provisions of the Trust Indenture Act of 1939. Initially, The Bank of New York,
a New York banking corporation, will be the property trustee until removed or
replaced by the holder of the common securities. For the purpose of compliance
with the provisions of the Trust Indenture Act of 1939, The Bank of New York
will also act as guarantee trustee. The fourth trustee, The Bank of New York
(Delaware), will act as the Delaware trustee for the purposes of the Delaware
Business Trust Act, until removed or replaced by the holder of the common
securities. See "Description of Securities -- The Guarantees."

     The property trustee will hold title to the applicable senior notes or
subordinated debenture for the benefit of the holders of the common securities
and the trust preferred securities and the property trustee will have the power
to exercise all rights, powers and privileges under the applicable indentures as
the holder of the senior notes or subordinated debenture. In addition, the
property trustee will maintain exclusive control of a segregated non-interest
bearing bank account to hold all payments made in respect of the senior notes or
subordinated debentures for the benefit of the holders of the common securities
and the trust preferred securities. The property trustee will make payments of
distributions and payments on liquidation, redemption and otherwise to the
holders of the common securities and the trust preferred securities out of funds
from the segregated non-interest bearing bank account. The guarantee trustee
will hold the guarantees for the benefit of the holders of the common securities
and the trust preferred securities. Consumers, as the direct or indirect holder
of all the common securities, will have the right to appoint, remove or replace
any of the trustees. Consumers will also have the right to increase or decrease
the number of trustees, as long as the number of trustees shall be at least
three, a majority of which shall be regular trustees. Consumers will pay all
fees and expenses related to the trusts and the offering of the common
securities and the trust preferred securities.

     The rights of the holders of the trust preferred securities, including
economic rights, rights to information and voting rights, are set forth in the
applicable amended and restated trust agreement, the Delaware Business Trust Act
and the Trust Indenture Act of 1939.

     The trustee for each trust in the State of Delaware is The Bank of New York
(Delaware), White Clay Center, Route 273, Newark, Delaware 19711.

     The principal place of business of each trust will be c/o Consumers Energy
Company, 212 West Michigan Avenue, Jackson, Michigan 49201.

                                USE OF PROCEEDS

     The proceeds received by each of the trusts from the sale of its trust
preferred securities or the common securities will be invested in the senior
notes or the subordinated debentures. As will be more specifically set forth in
the applicable prospectus supplement, Consumers will use those borrowed amounts
and the net proceeds from the sale of senior notes or subordinated debentures
offered hereby for its general corporate purposes, including capital
expenditures, investment in subsidiaries, working capital and repayment of debt.
Any specific allocation of the proceeds to a particular purpose that has been
made at the date of any prospectus supplement will be described in the
appropriate prospectus supplement.

DEBT SECURITIES

     Senior notes will be issued under a senior debt indenture. The subordinated
debentures will be issued under a subordinated debt indenture. The senior debt
indenture and the subordinated debt indenture are sometimes referred to in this
prospectus individually as an "indenture" and collectively as the "indentures".

     The following briefly summarizes the material provisions of the indentures
and the debt securities. You should read the more detailed provisions of the
applicable indenture, including the defined terms, for provisions that may be
important to you. You should also read the particular terms of a series of debt
securities, which will be described in more detail in the applicable prospectus
supplement. Copies of the indentures may be obtained from Consumers or the
applicable trustee.

     Unless otherwise provided in the applicable prospectus supplement, the
trustee under the senior debt indenture will be Chase Manhattan Bank and the
trustee under the subordinated debt indenture will be The Bank of New York.

General

     The indentures provide that debt securities of Consumers may be issued in
one or more series, with different terms, in each case as authorized on one or
more occasions by Consumers.

     Federal income tax consequences and other special considerations applicable
to any debt securities issued by Consumers at a discount will be described in
the applicable prospectus supplement.

     The applicable prospectus supplement relating to any series of debt
securities will describe the following terms, where applicable:

     - the title of the debt securities;

     - whether the debt securities will be senior or subordinated debt;

     - the total principal amount of the debt securities;

     - the percentage of the principal amount at which the debt securities will
       be sold and, if applicable, the method of determining the price;

     - the maturity date or dates;

     - the interest rate or the method of computing the interest rate;

     - the date or dates from which any interest will accrue, or how such date
       or dates will be determined, and the interest payment date or dates and
       any related record dates;

     - the location where payments on the debt securities will be made;

     - the terms and conditions on which the debt securities may be redeemed at
       the option of Consumers;

     - any obligation of Consumers to redeem, purchase or repay the debt
       securities at the option of a holder upon the happening of any event and
       the terms and conditions of redemption, purchase or repayment;

     - any provisions for the discharge of Consumers' obligations relating to
       the debt securities by deposit of funds or United States government
       obligations;

     - whether the debt securities are to trade in book-entry form and the terms
       and any conditions for exchanging the global security in whole or in part
       for paper certificates;

     - any material provisions of the applicable indenture described in this
       prospectus that do not apply to the debt securities;

                                        8
<PAGE>   42

     - any additional amounts with respect to the debt securities that Consumers
       will pay to a non-United States person because of any tax, assessment or
       governmental charge withheld or deducted and, if so, any option of
       Consumers to redeem the debt securities rather than paying these
       additional amounts;

     - any additional events of default; and

     - any other specific terms of the debt securities.

Concerning the Trustees

     Each of Chase Manhattan Bank, the trustee under the senior debt indenture
for the senior notes, and The Bank of New York, the trustee under the
subordinated debt indenture for the subordinated debentures, is one of a number
of banks with which Consumers and its subsidiaries maintain ordinary banking
relationships, including credit facilities.

Exchange and Transfer

     Debt securities may be presented for exchange. Registered debt securities
may be presented for registration of transfer at the offices and, subject to the
restrictions set forth in the debt security and in the applicable prospectus
supplement, without service charge, but upon payment of any taxes or other
governmental charges due in connection with the transfer, subject to any
limitations contained in the applicable indenture. Debt securities in bearer
form and any related coupons, will be transferable by delivery.

Payment

     Distributions on the debt securities in registered form will be made at the
office or agency of the applicable trustee in the Borough of Manhattan, the City
of New York or its other designated office. However, at the option of Consumers,
payment of any interest may be made by check or by wire transfer. Payment of any
interest due on debt securities in registered form will be made to the persons
in whose name the debt securities are registered at the close of business on the
record date for such interest payments. Payments made in any other manner will
be specified in the prospectus supplement.

Governing Law

     Each indenture and the debt securities will be governed by, and construed
in accordance with, the laws of the State of Michigan unless the laws of another
jurisdiction shall mandatorily apply. The rights, duties and obligations of the
subordinated note trustee are governed by and construed in accordance with the
laws of the State of New York.

SENIOR NOTES

General

     The following summaries of some important provisions of the senior note
indenture (including its supplements by such reference) do not purport to be
complete and are subject to, and qualified in their entirety by, all of the
provisions of the senior note indenture. The senior note indenture is
incorporated by reference in this prospectus and is available upon request to
the senior note trustee. In addition, capitalized terms used in this section and
not otherwise defined in this prospectus shall have the meaning given to them in
the senior note indenture.

Security; Release Date

     Until the release date (as described in the next paragraph), the senior
notes will be secured by one or more series of Consumers' first mortgage bonds
issued and delivered by Consumers to the senior note trustee. See "Description
of First Mortgage Bonds". Upon the issuance of a series of senior notes prior to

                                        9
<PAGE>   43

the release date, Consumers will simultaneously issue and deliver to the senior
note trustee, as security for all senior notes, a series of first mortgage bonds
that will have the same stated maturity date and corresponding redemption
provisions, and will be in the same total principal amount as the series of the
senior notes being issued. Any series of first mortgage bonds securing senior
notes may, but need not, bear interest. Any payment by Consumers to the senior
note trustee of principal of, interest and/or premium, if any, on a series of
first mortgage bonds will be applied by the senior note trustee to satisfy
Consumers' obligations with respect to principal of, interest and/or premium, if
any, on the corresponding senior notes.

     The "release date" will be the date that all first mortgage bonds of
Consumers issued and outstanding under a mortgage indenture with the Chase
Manhattan Bank as mortgage trustee, other than first mortgage bonds securing
senior notes, have been retired (at, before or after their maturity) through
payment, redemption or otherwise. On the release date, the senior note trustee
will deliver to Consumers, for cancellation, all first mortgage bonds securing
senior notes. Not later than 30 days thereafter, the senior note trustee will
provide notice to all holders of senior notes of the occurrence of the release
date. As a result, on the release date, the first mortgage bonds securing senior
notes will cease to secure the senior notes. The senior notes will then become
unsecured general obligations of Consumers and will rank equally with other
unsecured indebtedness of Consumers. Each series of first mortgage bonds that
secures senior notes will be secured by a lien on certain property owned by
Consumers. See "Description of First Mortgage Bonds -- Priority and Security."
Upon the payment or cancellation of any outstanding senior notes, the senior
note trustee will surrender to Consumers for cancellation an equal principal
amount of the related series of first mortgage bonds. Consumers will not permit,
at any time prior to the release date, the total principal amount of first
mortgage bonds securing senior notes held by the senior note trustee to be less
than the total principal amount of senior notes outstanding. Following the
release date, Consumers will cause the mortgage to be discharged and will not
issue any additional first mortgage bonds under the mortgage. While Consumers
will be precluded after the release date from issuing additional first mortgage
bonds, it will not be precluded under the senior note indenture or senior notes
from issuing or assuming other secured debt, or incurring liens on its property,
except to the extent indicated below under "-- Certain Covenants of
Consumers -- Limitation on Liens."

Events Of Default

     The following constitute events of default under senior notes of any
series:

          (1) failure to pay principal of and premium, if any, on any senior
     note of such series when due;

          (2) failure to pay interest on any senior note of such series when due
     for 60 days;

          (3) failure to perform any other covenant or agreement of Consumers in
     the senior notes of such series for 90 days after written notice to
     Consumers by the senior note trustee or the holders of at least 33% in
     total principal amount of the outstanding senior notes;

          (4) prior to the release date, a default under the mortgage; provided,
     however, that the waiver or cure of such default and the rescission and
     annulment of the consequences under the mortgage will be a waiver of the
     corresponding event of default under the senior note indenture and a
     rescission and annulment of the consequences under the senior note
     indenture; and

          (5) certain events of bankruptcy, insolvency, reorganization,
     assignment or receivership of Consumers.

     If an event of default occurs and is continuing, either the senior note
trustee or the holders of a majority in total principal amount of the
outstanding senior notes may declare the principal amount of all senior notes to
be due and payable immediately.

     The senior note trustee generally will be under no obligation to exercise
any of its rights or powers under the senior note indenture at the request or
direction of any of the holders of senior notes of such series unless those
holders have offered to the senior note trustee reasonable security or
indemnity. Subject to the provisions for indemnity and certain other limitations
contained in the senior note indenture, the

                                       10
<PAGE>   44

holders of a majority in principal amount of the outstanding senior notes of
such series generally will have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the senior note
trustee, or of exercising any trust or power conferred on the senior note
trustee. The holders of a majority in principal amount of the outstanding senior
notes of such series generally will have the right to waive any past default or
event of default (other than a payment default) on behalf of all holders of
senior notes of such series.

     No holder of senior notes of a series may institute any action against
Consumers under the senior note indenture unless:

          (1) that holder gives to the senior note trustee advance written
     notice of default and its continuance;

          (2) the holders of not less than a majority in total principal amount
     of senior notes of such series then outstanding affected by that event of
     default request the senior note trustee to institute such action;

          (3) that holder has offered the senior note trustee reasonable
     indemnity; and

          (4) the senior note trustee shall not have instituted such action
     within 60 days of such request.

     Furthermore, no holder of senior notes will be entitled to institute any
such action if and to the extent that that action would disturb or prejudice the
rights of other holders of senior notes of such series.

     Within 90 days after the occurrence of a default with respect to the senior
notes of a series, the senior note trustee must give the holders of the senior
notes of such series notice of any such default known to the senior note
trustee, unless cured or waived. The senior note trustee may withhold such
notice if it determines in good faith that it is in the interest of such holders
to do so except in the case of default in the payment of principal of, and
interest and/or premium, if any, on any senior notes of such series. Consumers
is required to deliver to the senior note trustee each year a certificate as to
whether or not, to the knowledge of the officers signing such certificate,
Consumers is in compliance with the conditions and covenants under the senior
note indenture.

Modification

     Consumers and the senior note trustee cannot modify and amend the senior
note indenture without the consent of the holders of a majority in principal
amount of the outstanding affected senior notes. Consumers and the senior note
trustee cannot modify and amend the senior note indenture without the consent of
the holder of each outstanding senior note of such series to:

          (1) change the maturity date of any senior note of such series;

          (2) reduce the rate (or change the method of calculation thereof) or
     extend the time of payment of interest on any senior note of such series;

          (3) reduce the principal amount of, or premium payable on, any senior
     note of such series;

          (4) change the coin or currency of any payment of principal of, and
     interest and/or premium on any senior note of such series;

          (5) change the date on which any senior note of such series may be
     redeemed or repaid at the option of its holder or adversely affect the
     rights of a holder to institute suit for the enforcement of any payment on
     or with respect to any senior note of such series;

          (6) impair the interest of the senior note trustee in the first
     mortgage bonds securing the senior notes of such series held by it or,
     prior to the release date, reduce the principal amount of any series of
     first mortgage bond securing the senior notes of such series to an amount
     less than the principal amount of the related series of senior notes or
     alter the payment provisions of such senior note mortgage bonds in a manner
     adverse to the holders of the senior notes; or

                                       11
<PAGE>   45

          (7) modify the senior notes of such series necessary to modify or
     amend the senior note indenture or to waive any past default to less than a
     majority.

     Consumers and the senior note trustee can modify and amend the senior note
indenture without the consent of the holders in certain cases, including:

          (1) to add to the covenants of Consumers for the benefit of the
     holders or to surrender a right conferred on Consumers in the senior note
     indenture;

          (2) to add further security for the senior notes of such series;

          (3) to add provisions enabling Consumers to be released with respect
     to one or more series of outstanding senior notes from its obligations
     under the covenants upon satisfaction of conditions with respect to such
     series of senior notes;

          (4) to supply omissions, cure ambiguities or correct defects which
     actions, in each case, are not prejudicial to the interests of the holders
     in any material respect; or

          (5) to make any other change that is not prejudicial to the holders of
     senior notes of such series in any material respect.

     A supplemental indenture which changes or eliminates any covenant or other
provision of the senior note indenture (or any supplemental indenture) which has
expressly been included solely for the benefit of one or more series of senior
notes, or which modifies the rights of the holders of senior notes of such
series with respect to such covenant or provision, will be deemed not to affect
the rights under the senior note indenture of the holders of senior notes of any
other series.

Defeasance and Discharge

     The senior note indenture provides that Consumers will be discharged from
any and all obligations in respect to the senior notes of such series and the
senior note indenture (except for certain obligations such as obligations to
register the transfer or exchange of senior notes, replace stolen, lost or
mutilated senior notes and maintain paying agencies) if, among other things,
Consumers irrevocably deposits with the senior note trustee, in trust for the
benefit of holders of senior notes of such series, money or certain United
States government obligations, or any combination of money or government
obligations. Through the payment of interest and principal on the deposits in
accordance with their terms must provide money in an amount sufficient, without
reinvestment, to make all payments of principal of, and any premium and interest
on, the senior notes on the dates such payments are due in accordance with the
terms of the senior note indenture and the senior notes of such series. But, if
all of the senior notes of such series are to be due within 90 days of such
deposit by redemption or otherwise, Consumers must also deliver to the senior
note trustee an opinion of counsel to the effect that the holders of the senior
notes of such series will not recognize income, gain or loss for federal income
tax purposes as a result of that defeasance or discharge of the senior note
indenture. Thereafter, the holders of senior notes must look only to the deposit
for payment of the principal of, and interest and any premium on, the senior
notes.

Consolidation, Merger and Sale or Disposition of Assets

     Consumers may consolidate with or merge into, or sell or otherwise dispose
of its properties as or substantially as an entirety if:

          (1) the new corporation is a corporation organized and existing under
     the laws of the United States of America, any state thereof, or the
     District of Columbia,

          (2) the new corporation assumes the due and punctual payment of the
     principal of and premium and interest on all the senior notes and the
     performance of every covenant of the senior note indenture to be performed
     or observed by Consumers and

          (3) if prior to the release date, the new corporation assumes
     Consumers' obligations under the mortgage indenture with respect to first
     mortgage bonds securing senior notes.
                                       12
<PAGE>   46

     The conveyance or other transfer by Consumers of:

          (1) all or any portion of its facilities for the generation of
     electric energy,

          (2) all of its facilities for the transmission of electric energy, or

          (3) all of its facilities for the distribution of natural gas, in each
     case considered alone or in any combination with properties described in
     (1), (2) or (3) of this sentence, will not be considered a conveyance or
     other transfer of all the properties of Consumers, as or substantially as
     an entirety.

Certain Covenants Of Consumers

     Limitation on Liens

     So long as any senior notes are outstanding, Consumers may not issue,
assume, guarantee or permit to exist after the release date any debt that is
secured by any mortgage, security interest, pledge or lien (each a "lien") of or
upon any operating property of Consumers, whether owned at the date of the
senior note indenture or thereafter acquired, without in any such case
effectively securing the senior notes (together with, if Consumers shall so
determine, any other indebtedness of Consumers ranking equally with the senior
notes) equally and ratably with such debt (but only so long as such debt is so
secured). The foregoing restriction will not apply to:

          (1) liens on any operating property existing at the time of its
     acquisition (which liens may also extend to subsequent repairs, alterations
     and improvements to such operating property);

          (2) liens on operating property of a corporation existing at the time
     such corporation is merged into or consolidated with, or such corporation
     disposes of its properties (or those of a division) as or substantially as
     an entirety to, Consumers;

          (3) liens on operating property to secure the cost of acquisition,
     construction, development or substantial repair, alteration or improvement
     of property or to secure indebtedness incurred to provide funds for any
     such purpose or for reimbursement of funds previously expended for any such
     purpose, provided such liens are created or assumed contemporaneously with,
     or within 18 months after, such acquisition or the completion of
     substantial repair or alteration, construction, development or substantial
     improvement;

          (4) liens in favor of any state or any department, agency or
     instrumentality or political subdivision of any state, or for the benefit
     of holders of securities issued by any such entity (or providers of credit
     enhancement with respect to such securities), to secure any debt
     (including, without limitation, obligations of Consumers with respect to
     industrial development, pollution control or similar revenue bonds)
     incurred for the purpose of financing all or any part of the purchase price
     or the cost of substantially repairing or altering, constructing,
     developing or substantially improving operating property of Consumers; or

          (5) any extension, renewal or replacement (or successive extensions,
     renewals or replacements), in whole or in part, of any lien referred to in
     clauses (1) through (4), provided, however, that the principal amount of
     debt secured thereby and not otherwise authorized by said clauses (1) to
     (4), inclusive, shall not exceed the principal amount of debt, plus any
     premium or fee payable in connection with any such extension, renewal or
     replacement, so secured at the time of such extension, renewal or
     replacement.

     These restrictions will not apply to the issuance, assumption or guarantee
by Consumers of debt secured by a lien which would otherwise be subject to the
foregoing restrictions up to a total amount which, together with all other
secured debt of Consumers (not including secured debt permitted under any of the
foregoing exceptions) and the value of sale and lease-back transactions existing
at such time (other than sale and lease-back transactions the proceeds of which
have been applied to the retirement of certain indebtedness, sale and lease-back
transactions in which the property involved would have been permitted to be
subjected to a lien under any of the foregoing exceptions in clauses (1) to (5)
and sale and

                                       13
<PAGE>   47

lease-back transactions that are permitted by the first sentence of "Limitation
on Sale and Lease-Back Transactions" below), does not exceed the greater of 15%
of Net Tangible Assets or 15% of Capitalization.

     Limitation on Sale and Lease-Back Transactions

     So long as senior notes are outstanding, Consumers may not enter into or
permit to exist after the release date any sale and lease-back transaction with
respect to any operating property (except for transactions involving leases for
a term, including renewals, of not more than 48 months), if the purchaser's
commitment is obtained more than 18 months after the later of the completion of
the acquisition, construction or development of such operating property or the
placing in operation of such operating property or of such operating property as
constructed or developed or substantially repaired, altered or improved. This
restriction will not apply if:

          (1) Consumers would be entitled under any of the provisions described
     in clauses (1) to (5) of the first sentence of the second paragraph under
     "Limitation on Liens" above to issue, assume, guarantee or permit to exist
     debt secured by a lien on such operating property without equally and
     ratably securing the senior notes,

          (2) after giving effect to such sale and lease-back transaction,
     Consumers could incur pursuant to the provisions described in the second
     sentence of the second paragraph under "Limitation on Liens," at least
     $1.00 of additional debt secured by liens (other than liens permitted by
     clause (1)), or

          (3) Consumers applies within 180 days an amount equal to, in the case
     of a sale or transfer for cash, the net proceeds (not exceeding the net
     book value), and, otherwise, an amount equal to the fair value (as
     determined by its Board of Directors) of the operating property so leased
     to the retirement of senior notes or other debt of Consumers ranking
     equally with, the senior notes, subject to reduction for senior notes and
     such debt retired during such 180-day period otherwise than pursuant to
     mandatory sinking fund or prepayment provisions and payments at stated
     maturity.

Voting Of Senior Note Mortgage Bonds Held By Senior Note Trustee

     The senior note trustee, as the holder of first mortgage bonds securing
senior notes, will attend any meeting of bondholders under the mortgage
indenture, or, at its option, will deliver its proxy in connection therewith as
it relates to matters with respect to which it is entitled to vote or consent.
So long as no event of default under the senior note indenture has occurred and
is continuing, the senior note trustee will vote or consent:

          (1) in favor of amendments or modifications of the mortgage indenture
     of substantially the same tenor and effect as follows:

           - to eliminate the maintenance and replacement fund and to recover
             amounts of net property additions previously applied in
             satisfaction thereof so that the same would become available as a
             basis for the issuance of first mortgage bonds;

           - to eliminate sinking funds or improvement funds and to recover
             amounts of net property additions previously applied in
             satisfaction thereof so that the same would become available as a
             basis for the issuance of first mortgage bonds;

           - to eliminate the restriction on the payment of dividends on common
             stock and to eliminate the requirements in connection with the
             periodic examination of the mortgaged and pledged property by an
             independent engineer;

           - to permit first mortgage bonds to be issued under the mortgage
             indenture in a principal amount equal to 70% of unfunded net
             property additions instead of 60%, to permit sinking funds
             improvement funds requirements (to the extent not otherwise
             eliminated) under the Mortgage to be satisfied by the application
             of net property additions in an amount equal to 70% of such
             additions instead of 60%, and to permit the acquisition of property
             subject to
                                       14
<PAGE>   48

             certain liens prior to the lien of the Mortgage if the principal
             amount of indebtedness secured by such liens does not exceed 70% of
             the cost of such property instead of 60%;

           - to eliminate requirements that Consumers deliver a net earnings
             certificate for any purpose under the mortgage indenture;

           - to raise the minimum dollar amount of insurance proceeds on account
             of loss or damage that must be payable to the senior note trustee
             from $50,000 to an amount equal to the greater of (A) $5,000,000
             and (B) three per centum (3%) of the total principal amount of
             first mortgage bonds outstanding;

           - to increase the amount of the fair value of property which may be
             sold or disposed of free from the lien of the mortgage indenture,
             without any release or consent by the senior note trustee, from not
             more than $25,000 in any calendar year to not more than an amount
             equal to the greater of (A) $5,000,000 and (B) three per centum
             (3%) of the total principal amount of first mortgage bonds then
             outstanding;

           - to permit certain mortgaged and pledged property to be released
             from the lien of the mortgage indenture if, in addition to certain
             other conditions, the senior note trustee receives purchase money
             obligations of not more than 70% of the fair value of such property
             instead of 60% and to eliminate the further requirement for the
             release of such property that the total principal amount of
             purchase money obligations held by the senior note trustee not
             exceed 20% of the principal amount of first mortgage bonds
             outstanding;

           - to eliminate the restriction prohibiting the mortgage trustee from
             applying cash held by it pursuant to the mortgage indenture to the
             purchase of bonds not otherwise redeemable at a price exceeding
             110% of the principal of such bonds, plus accrued interest; and

          (2) with respect to any other amendments or modifications of the
     mortgage indenture, as follows: the senior note trustee shall vote all
     first mortgage bonds securing senior notes then held by it, or consent with
     respect thereto, proportionately with the vote or consent of the holders of
     all other first mortgage bonds outstanding under the mortgage indenture,
     the holders of which are eligible to vote or consent. However, the senior
     note trustee will not vote in favor of, or consent to, any amendment or
     modification of the mortgage which, if it were an amendment or modification
     of the senior note indenture, would require the consent of senior notes
     holders (as described under "Modification,") without the prior consent of
     holders of senior notes which would be required for such an amendment or
     modification of the senior note indenture.

Concerning The Senior Note Trustee

     The Chase Manhattan Bank is both the senior note trustee under the senior
note indenture and the mortgage trustee under the mortgage indenture. Consumers
and its affiliates maintain depositary and other normal banking relationships
with The Chase Manhattan Bank. The Chase Manhattan Bank is also a lender to
Consumers and its affiliates. The senior note indenture provides that Consumers'
obligations to compensate the senior note trustee and reimburse the senior note
trustee for expenses, disbursements and advances will constitute indebtedness
which will be secured by a lien generally prior to that of the senior notes upon
all property and funds held or collected by the senior note trustee as such.

DESCRIPTION OF FIRST MORTGAGE BONDS

General

     The first mortgage bonds securing senior notes are to be issued under a
mortgage indenture as amended and supplemented by various supplemental
indentures with The Chase Manhattan Bank, as the mortgage trustee. The
statements herein concerning the mortgage indenture are an outline and do not
purport to be complete and are subject to, and qualified in their entirety by,
all of the provisions of the mortgage indenture, which is incorporated by
reference herein. They make use of defined terms and are

                                       15
<PAGE>   49

qualified in their entirety by express reference to the cited sections and
articles of the mortgage indenture a copy of which will be available upon
request to the senior note trustee.

     First mortgage bonds securing senior notes will be issued as security for
Consumers' obligations under the senior note indenture and will be immediately
delivered to and registered in the name of the senior note trustee. The first
mortgage bonds securing senior notes will be issued as security for senior notes
of a series and will secure the senior notes of that series until the release
date. The senior note indenture provides that the senior note trustee shall not
transfer any first mortgage bonds securing senior notes except to a successor
trustee, to Consumers (as provided in the senior note indenture) or in
compliance with a court order in connection with a bankruptcy or reorganization
proceeding of Consumers. The senior note trustee shall generally vote the first
mortgage bonds securing senior notes proportionately with what it believes to be
the vote of all other first mortgage bonds then outstanding except in connection
with certain amendments or modifications of the mortgage indenture, as described
under "Description of Senior Notes Voting of Senior Note Mortgage Bonds Held by
Senior Note Trustee."

     First mortgage bonds securing senior notes will correspond to the senior
notes of its related series in respect of principal amount, interest rate,
maturity date and redemption provisions. Upon payment of the principal or
premium, if any, or interest on senior notes of a series, the related first
mortgage bonds in a principal amount equal to the principal amount of such
senior notes will, to the extent of such payment of principal, premium or
interest, be deemed fully paid and the obligation of Consumers to make such
payment shall be discharged.

Priority And Security

     The first mortgage bonds securing senior notes of any series will rank
equally as to security with bonds of other series now outstanding or issued
later under the mortgage indenture. This security is a direct first lien on
substantially all of Consumers' property and franchises (other than certain
property expressly excluded from the lien (such as cash, bonds, stock and
certain other securities, contracts, accounts and bills receivables, judgments
and other evidences of indebtedness, stock in trade, materials or supplies
manufactured or acquired for the purpose of sale and/or resale in the usual
course of business or consumable in the operation of any of the properties of
Consumers, natural gas, oil and minerals, motor vehicles and certain real
property listed in Schedule A to the mortgage indenture)). This lien is subject
to excepted encumbrances (and certain other limitations) as defined and
described in the mortgage indenture. It is also subject to certain provisions of
Michigan law which provides that under certain circumstances, the State of
Michigan's lien against property on which it has incurred costs related to any
response activity that is subordinate to prior recorded liens can become
superior to such prior liens pursuant to court order. The mortgage indenture
permits, with certain limitations, the acquisition of property subject to prior
liens and, under certain conditions, permits the issuance of additional
indebtedness under such prior liens to the extent of 60% of net property
additions made by Consumers to the property subject to such prior liens.

Release And Substitution Of Property

     The mortgage indenture provides that, subject to various limitations,
property may be released from the lien thereof when sold or exchanged, or
contracted to be sold or exchanged, upon the basis of:

     - cash deposited with the mortgage trustee;

     - bonds or purchase money obligations delivered to the mortgage trustee;

     - prior lien bonds delivered to the mortgage trustee or reduced or assumed
       by the purchaser;

     - property additions acquired in exchange for the property released; or

     - upon a showing that unfunded net property additions exist. The mortgage
       indenture also permits the withdrawal of cash upon a showing that
       unfunded net property additions exist or against the deposit of bonds or
       the application thereof to the retirement of bonds.

                                       16
<PAGE>   50

Modification Of Mortgage

     The mortgage indenture, the rights and obligations of Consumers and the
rights of the bondholders may be modified by Consumers with the consent of the
holders of 75% in principal amount of the bonds and of not less than 60% of the
principal amount of each series affected. In general, however, no modification
of the terms of payment of principal or interest and no modification affecting
the lien or reducing the percentage required for modification is effective
against any bondholder without the bondholder's consent. Consumers has reserved
the right without any consent or other action by the holders of bonds of any
series created after September 15, 1993 or by the holder of any senior note or
exchange note, to amend the mortgage in order to substitute a majority in
principal amount of bonds outstanding under the mortgage for the 75% requirement
set forth above (and then only in respect of such series of outstanding bonds as
shall be affected by the proposed action) and to eliminate the requirement for a
series-by-series consent requirement.

Concerning The Mortgage Trustee

     The Chase Manhattan Bank is both the mortgage trustee under the mortgage
indenture and the senior note trustee under the senior note indenture. Consumers
and its affiliates maintain depositary and other normal banking relationships
with The Chase Manhattan Bank. The Chase Manhattan Bank is also a lender to
Consumers and its affiliates. The mortgage indenture provides that Consumers'
obligations to compensate the mortgage trustee and reimburse the trustee for
expenses, disbursements and advances will constitute indebtedness which will be
secured by a lien generally prior to that of the first mortgage bonds securing
senior notes upon all property and funds held or collected by the mortgage
trustee as such.

     The mortgage trustee or the holders of 20% in total principal amount of the
bonds may declare the principal due on default, but the holders of a majority in
total principal amount may annul such declaration and waive the default if the
default has been cured. Subject to certain limitations, the holders of a
majority in total principal amount may generally direct the time, method and
place of conducting any proceeding for the enforcement of the mortgage
indenture. No bondholder has the right to institute any proceedings for the
enforcement of the mortgage indenture unless that holder has given the mortgage
trustee written notice of a default, the holders of 20% of outstanding bonds
shall have tendered to the mortgage trustee reasonable security or indemnity
against costs, expenses and liabilities and requested the mortgage trustee to
take action, the mortgage trustee shall have declined to take action or failed
to do so within sixty days and no inconsistent directions shall have been given
by the holders of a majority in total principal amount of the bonds.

Defaults

     The mortgage defines the following as "defaults":

     - failure to pay principal when due;

     - failure to pay interest for sixty days;

     - failure to pay any installment of any sinking or other purchase fund for
       ninety days;

     - certain events in bankruptcy, insolvency or reorganization; and

     - failure to perform any other covenant for ninety days following written
       demand by the mortgage trustee for Consumers to cure such failure.

     Consumers has covenanted to pay interest on any overdue principal and (to
the extent permitted by law) on overdue installments of interest, if any, on the
bonds under the mortgage indenture at the rate of 6% per year. The mortgage
indenture does not contain a provision requiring any periodic evidence to be
furnished as to the absence of default or as to compliance with the terms
thereof. However, Consumers is required by law to furnish annually to the
trustee a certificate as to compliance with all conditions and covenants under
the mortgage indenture.

                                       17
<PAGE>   51

SUBORDINATED DEBENTURES

     The subordinated debentures will be issued under the subordinated debt
indenture and will rank subordinated and junior in right of payment, to the
extent set forth in the subordinated debt indenture, to all "senior
indebtedness" (as defined below) of Consumers.

     If Consumers defaults in the payment of any distributions on any senior
indebtedness when it becomes due and payable after any applicable grace period,
then, unless and until the default is cured or waived or ceases to exist,
Consumers cannot make a payment on account of or redeem or otherwise acquire the
subordinated debentures. The subordinated debt indenture provisions described in
this paragraph, however, do not prevent Consumers from making sinking fund
payments in subordinated debentures acquired prior to the maturity of senior
indebtedness or, in the case of default, prior to such default and notice
thereof. If there is any insolvency, bankruptcy, liquidation or other similar
proceeding relating to Consumers, its creditors or its property, then all senior
indebtedness must be paid in full before any payment may be made to any holders
of subordinated debentures. Holders of subordinated debentures must return and
deliver any payments received by them, other than in a plan of reorganization or
through a defeasance trust as described above, directly to the holders of senior
indebtedness until all senior indebtedness is paid in full.

     "Senior indebtedness" means distributions on the following, whether
outstanding on the date of execution of the subordinated debt indenture or
thereafter incurred, created or assumed:

     - indebtedness of Consumers for money borrowed by Consumers or evidenced by
       debentures (other than the subordinated debentures), notes, bankers'
       acceptances or other corporate debt securities or similar instruments
       issued by Consumers;

     - capital lease obligations of Consumers;

     - obligations of Consumers incurred for deferring the purchase price of
       property, with respect to conditional sales, and under any title
       retention agreement (but excluding trade accounts payable arising in the
       ordinary course of business);

     - obligations of Consumers with respect to letters of credit;

     - all indebtedness of others of the type referred to in the four preceding
       clauses assumed by or guaranteed in any manner by Consumers or in effect
       guaranteed by Consumers; or

     - renewals, extensions or refundings of any of the indebtedness referred to
       in the preceding three clauses unless, in the case of any particular
       indebtedness, renewal, extension or refunding, under the express
       provisions of the instrument creating or evidencing the same or the
       assumption or guarantee of the same, or pursuant to which the same is
       outstanding, such indebtedness or such renewal, extension or refunding
       thereof is not superior in right of payment to the subordinated debt
       securities.

     The subordinated debt indenture does not limit the total amount of senior
indebtedness that may be issued. As of June 30, 1999, senior indebtedness of
Consumers totaled approximately $2,728 million.

Certain Covenants

     If debt securities are issued to a trust or a trustee of such trust in
connection with the issuance of trust preferred securities of that trust,
Consumers will covenant that it will not (1) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of Consumers' capital stock or (2) make any payment of
principal, interest or premium, if any, on or repay or repurchase or redeem any
debt securities (including guarantees of indebtedness for money borrowed) of
Consumers that rank equal (in the case of subordinated debentures) with or
junior (in the case of senior and subordinated debentures) to that debt security
(other than (a) any dividend, redemption, liquidation, interest, principal or
guarantee payment by Consumers where the payment is made by way of securities
(including capital stock) that rank equal with or junior to the securities on

                                       18
<PAGE>   52

which such dividend, redemption, interest, principal or guarantee payment is
being made, (b) payments under the Consumers' guarantees of trust securities),
if at such time (1) there shall have occurred any event of which Consumers has
actual knowledge that (a) with the giving of notice or the lapse of time, or
both, would constitute an event of default under the indentures and (b) in
respect of which Consumers shall not have taken reasonable steps to cure, (2)
Consumers shall be in default with respect to its payment of any obligations
under the guarantees or (3) Consumers will have given notice of its selection of
an extension period as provided in the indentures with respect to the Debt
Securities and will not have rescinded such notice, or such extension period, or
any extension thereof, shall be continuing.

     Consumers will also covenant:

          (1) to maintain directly or indirectly 100% ownership of the common
     securities, provided that certain successors which are permitted pursuant
     to the indentures may succeed to Consumers' ownership of the common
     securities,

          (2) not to voluntarily dissolve, wind-up or liquidate the trust,
     except:

             (a) in connection with a distribution of the debt securities to the
        holders of the trust preferred securities in liquidation of such trust
        or

             (b) in connection with certain mergers, consolidations or
        amalgamations permitted by the amended and restated trust agreement, and

          (3) to use its reasonable efforts, consistent with the terms and
     provisions of the amended and restated trust agreement, to cause such trust
     to remain classified as a grantor trust and not as an association taxable
     as a corporation for United States federal income tax purposes.

Events of Default

     The subordinated debt indenture provides that events of default regarding
any series of subordinated debentures will be:

     - failure to pay required interest on any subordinated debentures of such
       series for 30 days;

     - failure to pay principal other than a scheduled installment payment or
       premium, if any, on any subordinated note of such series when due;

     - failure to make any required scheduled installment payment on
       subordinates notes of such series;

     - failure to perform for 60 days after notice any other covenant in the
       relevant indenture other than a covenant included in the relevant
       indenture solely for the benefit of a series of subordinated debentures
       other than such series;

     - certain events of bankruptcy or insolvency, whether voluntary or not; and

     - if subordinated debentures are issued, such trust is voluntarily or
       involuntarily dissolved, wound-up or terminated, except in connection
       with the distribution of subordinated debentures to the holders of the
       common securities and the trust preferred securities in liquidation of
       the trust, the redemption of all outstanding trust securities of the
       trust and certain mergers, consolidation or amalgamations permitted by
       the declaration of that trust.

     If an event of default regarding subordinated debentures of any series
issued should occur and be continuing, either the subordinated note trustee or
the holders of 25% in the principal amount of outstanding subordinated
debentures of such series may declare each subordinated note of that series due
and payable.

     Holders of a majority in principal amount of the outstanding subordinated
debentures of any series will be entitled to control certain actions of the
subordinated note trustee and to waive past defaults regarding such series. The
trustee generally will not be requested, ordered or directed by any of the
holders

                                       19
<PAGE>   53

of subordinated debentures, unless one or more of such holders shall have
offered to the trustee reasonable security or indemnity.

     Before any holder of any series of subordinated debentures may institute
action for any remedy, except payment on such holder's subordinated debentures
when due, the holders of not less than 25% in principal amount of the
subordinated debentures of that series outstanding must request the subordinated
note trustee to take action. Holders must also offer and give the satisfactory
security and indemnity against liabilities incurred by the trustee for taking
such action.

     Consumers is required to annually furnish the subordinated note trustee a
statement as to Consumers' compliance with all conditions and covenants under
the subordinated debt indenture. The subordinated debt indenture provides that
the subordinated note trustee may withhold notice to the holders of the
subordinated debentures of any series of any default affecting such series,
except payment on holders' subordinated debentures when due, if it considers
withholding notice to be in the interests of the holders of the subordinated
debentures of such series.

Consolidation, Merger or Sale of Assets

     The subordinated debt indenture provides that Consumers may consolidate
with or merge into, or sell, lease or convey its property as an entirety or
substantially as an entirety to, any other corporation if the new corporation
assumes the obligations of Consumers under the subordinated debentures and the
subordinated debt indenture and is organized and existing under the laws of the
United States of America, any U.S. state or the District of Columbia.

Modification of the Indenture

     The subordinated debt indenture permits Consumers and the subordinated note
trustee to enter into supplemental indentures without the consent of the holders
of the subordinated debentures to establish the form and terms of any series of
securities under the the subordinated debt indentures.

     The subordinated debt indenture also permits Consumers and the subordinated
note trustee, with the consent of the holders of at least a majority in total
principal amount of the subordinated debentures of all series then outstanding
and affected (voting as one class), to change in any manner the provisions of
the subordinated debt indenture or modify in any manner the rights of the
holders of the subordinated debentures of each such affected series. Consumers
and the relevant trustee may not, without the consent of the holder of each
subordinated debenture affected, enter into any supplemental indenture to:

     - change the time of payment of the principal;

     - reduce the principal amount of such subordinated debentures;

     - reduce the rate or change the time of payment of interest on such
       subordinated debentures;

     - impair the right to institute suit for the enforcement of any payment on
       any subordinated debentures when due.

     In addition, no such modification may reduce the percentage in principal
amount of the subordinated debentures of the affected series, the consent of
whose holders is required for any such modification or for any waiver provided
for in the subordinated debt indenture.

     Prior to the acceleration of the maturity of any subordinated debentures,
the holders, voting as one class, of a majority in total principal amount of the
subordinated debentures with respect to which a default or event of default has
occurred and is continuing, may, on behalf of the holders of all such affected
subordinated debentures, waive any past default or event of default and its
consequences, except a default or an event of default in respect of a covenant
or provision of the applicable indenture or of any subordinated debenture which
cannot be modified or amended without the consent of the holder of each
subordinated debentures affected.

Defeasance, Covenant Defeasance and Discharge

     The subordinated debt indenture provides that, at the option of Consumers,
Consumers will be discharged from all obligations in respect of the subordinated
debentures of a particular series then outstanding (except for certain
obligations to register the transfer of or exchange the subordinated debentures
of such series, to replace stolen, lost or mutilated subordinated debentures of
such series, to maintain paying agencies and to maintain the trust described
below).

     If Consumers in each case irrevocably deposits in trust with the relevant
trustee money, and/or securities backed by the full faith and credit of the
United States which, through the payment of the principal thereof and the
interest thereon in accordance with their terms, will provide money in an amount
sufficient to pay all the principal and interest on the subordinated debentures
of such series on the stated maturities of such subordinated debentures in
accordance with the terms thereof.

     To exercise this option, Consumers is required to deliver to the relevant
trustee an opinion of independent counsel to the effect that the exercise of
such option would not cause the holders of the subordinated debentures of such
series to recognize income, gain or loss for United States federal income tax
purposes as a result of such defeasance, and such holders will be subject to
United States federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such defeasance had not occurred.

TRUST PREFERRED SECURITIES

GENERAL

     Each trust may issue, on one or more occasion, trust preferred securities
having terms described in the prospectus supplement relating thereto. The
amended and restated trust agreement of each trust will authorize the
establishment of no more than one series of trust preferred securities, having
such terms, including distributions, redemption, voting, liquidation rights and
such other preferred, deferred or other special rights or such rights or
restrictions as shall be set forth therein or otherwise established by the
trustees pursuant thereto. Reference is made to the prospectus supplement
relating to the trust preferred securities for specific terms, including:

     - the distinctive designation and the number of trust preferred securities
       to be offered which will represent undivided beneficial interests in the
       assets of the trust;

     - the annual distribution rate and the dates or date upon which such
       distributions will be paid, provided, however distributions on the trust
       preferred securities will be paid quarterly in arrears to holders of
       trust preferred securities as of a record date on which the trust
       preferred securities are outstanding;

     - whether distributions on trust preferred securities would be deferred
       during any deferral of interest payments on the debt securities,
       provided, however that no such deferral, including extensions, if any,
       may exceed 20 consecutive quarters nor extend beyond the stated maturity
       date of the debt securities, and at the end of any such deferrals,
       Consumers will make all interest payments then accrued or deferred and
       unpaid (including any compounded interest);

     - the amount of any liquidation preference;

     - the obligation, if any, of the trust to redeem trust preferred securities
       through the exercise of Consumers of an option on the corresponding debt
       securities and the price or prices at which, the period or periods within
       which and the terms and conditions upon which trust preferred securities
       will be purchased or redeemed, in whole or in part, under to such
       obligation;

     - the period or periods within which and the terms and conditions, if any,
       including the price or prices or the rate or rates of conversion or
       exchange and the terms and conditions of any adjustments, upon which the
       trust preferred securities shall be convertible or exchangeable at the
       option of the holder of the trust preferred securities of other property
       or cash;

                                       21
<PAGE>   55

     - the voting rights, if any, of the trust preferred securities in addition
       to those required by law and in the amended and restated trust agreement,
       or set forth under a Consumers' guarantee (as defined below);

     - the additional payments, if any, which the trust will pay as a
       distribution as necessary so that the net amounts reserved by the trust
       and distributable to the holders of the trust preferred securities, after
       all taxes, duties, assessments or governmental charges of whatever nature
       (other than withholding taxes) have been paid will not be less than the
       amount that would have been reserved and distributed by the trust, and
       the amount the holders of the trust preferred securities would have
       reserved, had no such taxes, duties, assessments or governmental charges
       been imposed;

     - the terms and conditions, if any, upon which the debt securities may be
       distributed to holders of trust preferred securities; and

     - any other relative rights, powers, preferences, privileges, limitations
       or restrictions of the trust preferred securities not inconsistent with
       the amended and restated trust agreement or applicable law.

     All trust preferred securities offered hereby will be irrevocably
guaranteed by Consumers, on a senior or subordinated basis, as applicable, and
to the extent set forth below under "The Guarantees." Any applicable federal
income tax considerations applicable to any offering of the trust preferred
securities will be described in the prospectus supplement relating thereto. The
total number of trust preferred securities which the trust shall have authority
to issue will be pursuant to the terms of the amended and restated trust
agreement.

EFFECT OF OBLIGATIONS UNDER THE DEBT SECURITIES AND THE GUARANTEES

     As set forth in the amended and restated trust agreements, the sole purpose
of the trusts are to issue the common securities and the trust preferred
securities evidencing undivided beneficial interests in the assets of each of
the trusts, and to invest the proceeds from such issuance and sale to acquire
directly the debt securities from Consumers.

     As long as payments of interest and other payments are made when due on the
debt securities, such payments will be sufficient to cover distributions and
payments due on the common securities and the trust preferred securities because
of the following factors:

     - the total principal amount of debt securities will be equal to the sums
       of the total stated liquidation amount of the common securities and the
       trust preferred securities;

     - the interest rate and the interest and other payment dates on the debt
       securities will match the distribution rate and distribution and other
       payment dates for the common securities and the trust preferred
       securities;

     - Consumers will pay all, and each trust shall not be obligated to pay,
       directly or indirectly, all its costs, expenses, debt and obligations
       (other than with respect to the common securities and the trust preferred
       securities); and

     - the amended and restated trust agreement further provides that Consumers
       trustees will not take or cause or permit the trust to, among other
       things, engage in any activity that is not consistent with the purposes
       of the trust.

     Payments of distributions (to the extent funds for distributions are
available) and other payments due on the trust preferred securities (to the
extent funds for other payments are available) are guaranteed by Consumers as
and to the extent discussed under "The Guarantees" below. If Consumers does not
make interest payments on the debt securities purchased by the trust, it is
expected that the trusts will not have sufficient funds to pay distributions on
the trust preferred securities. The Consumers guarantees do not apply to any
payment of distributions unless and until the trusts have sufficient funds for
the payment of distributions and other payments on the trust preferred
securities only if and to the extent that Consumers

                                       22
<PAGE>   56

has made a payment of interest or principal on the debt securities held by the
trusts as their sole asset. The Consumers guarantees, when taken together with
Consumers' obligations under the debt securities and the related indenture and
its obligations under the applicable amended and restated trust agreement,
including its obligations to pay costs, expenses, debts and liabilities of the
trust (other than with respect to the common securities and the trust preferred
securities), provide a full and unconditional guarantee of amounts on the trust
preferred securities.

     If Consumers fails to make interest or other payments on the debt
securities when due (taking account of any extension period), the applicable
amended and restated trust agreements provide a mechanism whereby the holders of
the trust preferred securities may direct a property trustee to enforce its
rights under the debt securities. If a property trustee fails to enforce its
rights under the debt securities, a holder of trust preferred securities may, to
the fullest extent permitted by applicable law, institute a legal proceeding
against Consumers to enforce a property trustee's rights under the debt
securities without first instituting any legal proceeding against a property
trustee or any other person or entity. Notwithstanding the foregoing, if an
event of default has occurred and is continuing under the applicable amended and
restated trust agreement, and such event is attributable to the failure of
Consumers to pay interest or principal on the debt securities on the date such
interest or principal is otherwise payable (or in the case of redemption on the
redemption date), then a holder of trust preferred securities may institute
legal proceedings directly against Consumers to obtain payment. If Consumers
fails to make payments under the guarantees, the guarantees provide a mechanism
whereby the holders of the trust preferred securities may direct a guarantee
trustee to enforce its rights thereunder. Any holder of trust preferred
securities may institute a legal proceeding directly against Consumers to
enforce a guarantee trustee's rights under a guarantee without first instituting
a legal proceeding against the trust, the guarantee trustee, or any other person
or entity.

THE GUARANTEES

     Set forth below is a summary of information concerning the guarantees which
will be executed and delivered by Consumers for the benefit of the holders, from
time to time, of the trust preferred securities. Each guarantee will be
qualified as an indenture under the Trust Indenture Act of 1939. The Bank of New
York will act as indenture trustee under the guarantees for the purpose of
compliance with the provisions of the Trust Indenture Act of 1939. This summary
does not purport to be complete and is subject in all respects to the provisions
of, and is qualified in its entirety by reference to, the guarantees, which is
filed as an exhibit to the Registration Statement of which this prospectus forms
a part.

General

     Consumers will irrevocably agree to pay in full, on a senior or
subordinated basis, as applicable, to the extent set forth herein, the guarantee
payments (as described below) to the holders of the trust preferred securities,
as and when due, regardless of any defense, right of set-off or counterclaim
that the trust may have or assert other than the defense of payment. The
following payments with respect to the trust preferred securities, to the extent
not paid by or on behalf of the trust, will be subject to a guarantee by
Consumers of:

          (1) any accumulated and unpaid distributions required to be paid on
     the trust preferred securities, to the extent that the trust has funds on
     hand available therefor at such time;

          (2) the redemption price with respect to any trust preferred
     securities called for redemption to the extent that the trust has funds on
     hand available therefor at such time; or

          (3) upon a voluntary or involuntary dissolution, winding up or
     liquidation of the trust (unless the debt securities are distributed to
     holders of the trust preferred securities), the lesser of (a) the
     liquidation distribution, to the extent that the trust has funds on hand
     available the distribution at such time, and (b) the amount of assets of
     the trust remaining available for distribution to holders of trust
     preferred securities.

                                       23
<PAGE>   57

     Consumers' obligation to make a guarantee payment may be satisfied by
direct payment of the required amounts of Consumers to the holders of the trust
preferred securities or by causing the trust to pay such amount to such holders.

     The Consumers guarantees will be irrevocable guarantees, on a senior or
subordinated basis, as applicable, of the trust's obligations under the trust
preferred securities, but will apply only to the extent that the trust has funds
sufficient to make such payments, and are not guarantees of collection. If
Consumers does not make interest payments on the debt securities held by the
trust, the trust will not be able to pay distributions on the trust preferred
securities and will not have funds legally available therefor.

     Consumers has, through the guarantees, the applicable amended and restated
trust agreements, the senior notes, the subordinated debentures, and the
indentures, taken together, fully, irrevocably and unconditionally guaranteed
all of the trust's obligations under the trust preferred securities. No single
document standing alone or operating in conjunction with fewer than all of the
other documents constitutes such guarantee. It is only the combined operation of
these documents that has the effect of providing a full, irrevocable and
unconditional guarantee of the trust's obligations under the trust preferred
securities.

     Consumers has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the trust with respect to the common securities to
the same extent as the guarantees of the preferred securities, except that upon
the occurrence and during the continuation of a amended and restated trust
agreement Event of Default, holders of trust preferred securities shall have
priority over holders of common securities with respect to distributions and
payments on liquidation, redemption or otherwise.

Certain Covenants of Consumers

     Consumers will also covenant that it will not

          (1) declare or pay any dividends or distributions on, or redeem,
     purchase, acquire, or make a liquidation payment with respect to, any of
     Consumers' capital stock or

          (2) make any payment of principal, interest or premium, if any, on or
     repay or repurchase or redeem any debt securities (including guarantees of
     indebtedness for money borrowed) of Consumers that rank equal (in the case
     of subordinated debentures with or junior in the case of the senior and
     subordinated debentures) to the debt securities (other than (a) any
     dividend, redemption, liquidation, interest, principal or guarantee payment
     by Consumers where the payment is made by way of securities (including
     capital stock) that rank equal with or junior to the securities on which
     such dividend, redemption, interest, principal or guarantee payment is
     being made, (b) payments under the Consumers guarantees of the trust
     securities, (c) as a result of a reclassification of Consumers' capital
     stock or the exchange or conversion of one series or class of Consumers'
     capital stock for another series or class of Consumers' capital stock and
     (d) the purchase of fractional interests in shares of Consumers' capital
     stock pursuant to the conversion or exchange provisions of such capital
     stock or the security being converted or exchanged) if at such time (1)
     there shall have occurred any event of which Consumers has actual knowledge
     that (a) with the giving of notice or the lapse of time, or both, would
     constitute a event of default and (b) in respect of which Consumers shall
     not have taken reasonable steps to cure, (2) Consumers shall be in default
     with respect to its payment of any obligations under the guarantee or

          (3) Consumers shall have given notice of its selection of an extension
     period as provided in the indentures with respect to the debt securities
     and shall not have rescinded such notice, or such extension period, or any
     extension thereof, shall be continuing.

     Consumers also will covenant to:

          (1) maintain directly or indirectly 100% ownership of the common
     securities, provided that certain successors which are permitted pursuant
     to the indentures may succeed to Consumers' ownership of the common
     securities,

                                       24
<PAGE>   58

          (2) not voluntarily dissolve, wind-up or liquidate the trust, except:

           - in connection with a distribution of the debt securities to the
             holders of the trust preferred securities in liquidation of the
             trust, or

           - in connection with certain mergers, consolidations or amalgamations
             permitted by the amended and restated trust agreement, and

          (3) use its reasonable efforts, consistent with the terms and
     provisions of the applicable amended and restated trust agreement, to cause
     the trust to remain classified as a grantor trust and not as an association
     taxable as a corporation for United States federal income tax purposes.

Amendments and Assignment

     Except with respect to any changes which do not materially adversely affect
the rights of holders of the trust preferred securities (in which case no vote
will be required), the Consumers guarantees of the trust preferred securities
may not be amended without the prior approval of the holders of not less than a
majority in total liquidation amount of such outstanding trust preferred
securities. All guarantees and agreements contained in the guarantees shall bind
the successors, assigns, receivers, trustees and representatives of Consumers
and shall inure to the benefit of the holders of the trust preferred securities
then outstanding.

Termination of the Guarantees

     The Consumers guarantees of the trust preferred securities will terminate
and be of no further force and effect upon full payment of the redemption price
of the trust preferred securities, upon full payment of the amounts payable upon
liquidation of the trust or upon distribution of the debt securities to the
holders of the trust preferred securities in exchange for all of the trust
preferred securities. The guarantees will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of trust preferred
securities must restore payment of any sums paid under such trust preferred
securities or the guarantees.

Events of Default

     An event of default under a Consumers guarantee of the trust preferred
securities will occur upon the failure of Consumers to perform any of its
payment or other obligations thereunder. The holders of a majority in total
liquidation amount of the trust preferred securities have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to a guarantee trustee in respect of a guarantee or to direct the exercise of
any trust or power conferred upon a guarantee trustee under the guarantees.

     If a guarantee trustee fails to enforce a Consumers guarantee of the trust
preferred securities, any holder of the trust preferred securities may institute
a legal proceeding directly against Consumers to enforce its rights under such
guarantee without first instituting a legal proceeding against the trust, the
guarantee trustee or any other person or entity. In addition, any record holder
of trust preferred securities shall have the right, which is absolute and
unconditional, to proceed directly against Consumers to obtain guarantee
payments, without first waiting to determine if the guarantee trustee has
enforced a guarantee or instituting a legal proceeding against the trust, the
guarantee trustee or any other person or entity. Consumers has waived any right
or remedy to require that any action be brought just against the trust, or any
other person or entity before proceeding directly against Consumers.

                                       25
<PAGE>   59

Status of the Guarantees

     The Consumers guarantee of the trust preferred securities will constitute
unsecured obligations of Consumers and will rank:

          (1) equal to or subordinate and junior in right of payment to all
     other liabilities of Consumers, as applicable,

          (2) equal with the most senior preferred stock now or hereafter issued
     by Consumers and with any guarantee now or hereafter entered into by
     Consumers in respect of any preferred or preference stock of any affiliate
     of Consumers, and

          (3) senior to Consumers' common stock.

     The Consumers guarantee of the trust preferred securities will constitute a
guarantee of payment and not of collection (i.e., the guaranteed party may
institute a legal proceeding directly against the guarantor to enforce its
rights under the guarantee without first instituting a legal proceeding against
any other person or entity). The guarantees will be held for the benefit of the
holders of the trust preferred securities. The guarantees will not be discharged
except by payment of the guarantee payments in full to the extent not paid by
the trust or upon distribution of the debt securities to the holders of the
trust preferred securities. The guarantees do not place a limitation on the
amount of additional indebtedness that may be incurred by Consumers.

                                    EXPERTS

     The consolidated financial statements and schedule of Consumers as of
December 31, 1998 and 1997, and for each of the three years in the period ended
December 31, 1998 incorporated by reference in this prospectus, have been
audited by Arthur Andersen LLP, independent public accountants, as indicated in

                                       27
<PAGE>   61

their reports with respect thereto, and are included herein in reliance upon the
authority of said firm as experts in accounting and auditing in giving said
reports.

     With respect to the unaudited interim consolidated financial information
for the periods ended March 31 and June 30, 1999 and 1998, Arthur Andersen LLP
has applied limited procedures in accordance with professional standards for a
review of that information. However, their separate reports thereon state that
they did not audit and they did not express an opinion on that interim
consolidated financial information.

     Accordingly, the degree of reliance on their reports on that information
should be restricted in light of the limited nature of the review procedures
applied. In addition, the accountants are not subject to the liability
provisions of Section 11 of the Securities Act, for their reports on the
unaudited interim consolidated financial information because these reports are
not "reports" or a part of the registration statement prepared or certified by
the accountants within the meaning of Sections 7 and 11 of the Securities Act.

     Future consolidated financial statements of Consumers and the reports
thereon of Arthur Andersen LLP also will be incorporated by reference in this
prospectus in reliance upon the authority of that firm as experts in giving
those reports to the extent that said firm has audited said consolidated
financial statements and consented to the use of their reports thereon.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The following resolution was adopted by the Board of Directors of Consumers
on May 6, 1987:

     RESOLVED: That effective March 1, 1987 the Company shall indemnify to the
full extent permitted by law every person (including the estate, heirs and legal
representatives of such person in the event of the decease, incompetency,
insolvency or bankruptcy of such person) who is or was a director, officer,
partner, trustee, employee or agent of the Company, or is or was serving at the
request of the Company as a director, officer, partner, trustee, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against all liability, costs, expenses, including attorneys' fees,
judgments, penalties, fines and amounts paid in settlement, incurred by or
imposed upon the person connection with or resulting from any claim or any
threatened, pending or completed action, suit or proceeding whether civil,
criminal, administrative, investigative or of whatever nature, arising from the
person's service or capacity as, or by reason of the fact that the person is or
was, a director, officer, partner, trustee, employee or agent of the Company or
is or was serving at the request of the Company as a director, officer, partner,
trustee, employee or agent of another corporation partnership, joint venture,
trust or other enterprise. Such right of indemnification shall not be deemed
exclusive of any other rights to which the person may be entitled under statute,
bylaw, agreement, vote of shareholders or otherwise.

     Article XIII, Section 1 of Consumers Bylaws provides:

     The Company may purchase and maintain liability insurance, to the full
extent permitted by law, on behalf of any person who is or was a director,
officer, employee or agent of the Company, or is or was serving at the request
of the Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against such person and incurred by such person in any such capacity.

     Article V of Consumers Restated Articles of Incorporation, as amended
reads:

     A director shall not be personally liable to the Company or its
shareholders for monetary damages for breach of duty as a director except (i)
for a breach of the director's duty of loyalty to the Company or its
shareholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for a violation of
Section 551(1) of the Michigan Business Corporation Act, and (iv) any
transaction from which the director derived an improper personal benefit. No
amendment to or repeal of this Article V, and no modification to its provisions
by law, shall apply to, or have any effect upon, the liability or alleged
liability of any director of the Company for or with respect to any acts or
omissions of such director occurring prior to such amendment, repeal or
modification.

                                      II-1
<PAGE>   64

     Article VI of Consumers Restated Articles of Incorporation, as amended
reads:

     Each director and each officer of the Company shall be indemnified by the
Company to the fullest extent permitted by law against expenses (including
attorneys' fees), judgments, penalties, fines and amounts paid in settlement
actually and reasonably incurred by him or her in connection with the defense of
any proceeding in which he or she was or is a party or is threatened to be made
a party by reason of being or having been a director or an officer of the
Company. Such right of indemnification is not exclusive of any other rights to
which such director or officer may be entitled under any now or thereafter
existing statute, any other provision of these Articles, bylaw, agreement, vote
of shareholders or otherwise. If Business Corporation Act of the State of
Michigan is amended after approval by the shareholders of this Article VI to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Company shall be
eliminated or limited to the fullest extent permitted by the Business
Corporation Act of the State of Michigan, as so amended. Any repeal or
modification of this Article VI by the shareholders of the Company shall not
adversely affect any right or protection of a director of the Company existing
at the time of such repeal or modification.

     Sections 561 through 571 of the Michigan Business Corporation Act provides
Consumers with the power to indemnify directors, officers, employees and agents
against certain expenses and payments, and to purchase and maintain insurance on
behalf of directors, officers, employees and agents.

     Officers and directors are covered within specified monetary limits by
insurance against certain losses arising from claims made by reason of their
being directors or officers of Consumers or of Consumers' subsidiaries and
Consumers' officers and directors are indemnified against such losses by reason
of their being or having been directors of officers of another corporation,
partnership, joint venture, trust or other enterprise at Consumers' request. In
addition, Consumers has indemnified each of its present directors by contracts
that contain affirmative provisions essentially similar to those in Sections 561
through 571 of the Michigan Business Corporation Act cited above.

     Officers and directors and Regular Trustees of the trust are covered within
specified monetary limits by insurance against certain losses arising from
claims made by reason of their being directors or officers of Consumers or of
Consumers' subsidiaries and Consumers' officers and directors are indemnified
against such losses by reason of their being or having been directors of
officers or another corporation, partnership, joint venture, trust or other
enterprise at Consumers' request. In addition, Consumers has indemnified each of
its present directors by contracts that contain affirmative provisions
essentially similar to those in sections 561 through 571 of the Michigan
Business Corporation Act cited above.

     The amended and restated trust agreement provides that to the fullest
extent permitted by applicable law, Consumers shall indemnify and hold harmless
each of the Trustees, any Affiliate of the Trustees, any officer, director,
shareholder, employee, representative or agent of any Trustee and any employee
or agent of the trust or its Affiliates (each a "Indemnified Person"), from and
against any loss, damage, liability, tax, penalty, expense or claim of any kind
or nature whatsoever incurred by such Indemnified Person by reason the creation,
operation or termination of the trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by the amended and restated trust
agreement, except that no Indemnified Person shall be entitled to be indemnified
in respect of any loss, damage or claim incurred by such Indemnified Person by
reason of negligence or willful misconduct with respect to such acts or
omissions.

ITEM 17. UNDERTAKINGS.

     The undersigned registrants hereby undertake:

          (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

                                      II-4
<PAGE>   67

     arising after the effective date of the registration statement (or the most
     recent post-effective amendment thereof) which, individually or in the
     total, 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 total, the changes in volume and price represent no
     more than a 20% change in the maximum total offering price set forth in the
     "Calculation of Registration Fee" table in the effective registration
     statement; (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 (i) and (ii) do not apply if the registration
     statement is on Form S-3 or Form S-8, and 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 post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

          (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 this registration statement
     shall be deemed to be a new registration statement relating to the
     securities offered herein, and the offering of such securities at that time
     shall be deemed to be the initial bona fide offering thereof.

          (5) 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 Securities and Exchange Commission such indemnification
     is against public policy as expressed in the Act and is, therefore,
     unenforceable. In the event that as 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
     be governed by the final adjudication of such issue.

          (6) That (1) for purposes of determining any liability under the
     Securities Act of 1933, the information omitted from the form of prospectus
     filed as 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 as of the time it was declared
     effective; and (2) for the purpose of determining any liability under the
     Securities Act of 1933, each post-effective amendment that contains a form
     of prospectus 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.
