the Preferred Securities, in each case out of funds held by the Trust, will be
irrevocably guaranteed by the Company to the extent described herein (the
"Guarantee"). Certain payments in respect of the Common Securities may also be
guaranteed by the Company. See "Description of the Guarantee." Unless otherwise
set forth in the applicable Prospectus Supplement, the obligations of the
Company under the Guarantee will be senior unsecured obligations of the Company
and will rank pari passu with all of the Company's other senior unsecured
obligations. Concurrently with the issuance by the Trust of the Preferred
Securities, the Trust will invest the proceeds thereof and any contributions
made in respect of the Common Securities in the Trust Debentures, which will
have terms corresponding to the terms of
 
                                        2

(continued from previous page)
the Preferred Securities. The Trust Debentures will be the sole assets of the
Trust, and payments under the Trust Debentures and those made by the Company in
respect of fees and expenses incurred by the Trust will be the only revenue of
the Trust. Upon the occurrence of certain events as are described herein and in
the accompanying Prospectus Supplement, the Company may redeem the Trust
Debentures and cause the redemption of the Trust Securities. In addition, if
provided in the applicable Prospectus Supplement, the Company may dissolve the
Trust at any time and, after satisfaction of the liabilities to creditors of the
Trust as provided by applicable law, cause the Trust Debentures to be
distributed to the holders of the Trust Securities in liquidation of their
interest in the Trust.
 
     Taken together, the Company's obligations under the Trust Debentures, the
Debenture Indenture (as defined herein), the Declaration (as defined herein) and
the Guarantee, in the aggregate, have the effect of providing a full,
irrevocable and unconditional guarantee of payments of distributions and other
amounts due on the Preferred Securities. See "Relationship Among the Preferred
Securities, the Trust Debentures and the Guarantee."

                                   THE TRUST
 
     The Trust is a statutory business trust created under Delaware law pursuant
to (i) a declaration of trust, dated as of January 15, 1998, and entered into by
the Company, as sponsor (the "Sponsor") and the trustee named herein and (ii)
the filing of a certificate of trust with the Secretary of State of the State of
Delaware on January 15, 1998. The declaration will be amended and restated in
its entirety (as so amended and restated, the "Declaration"), substantially in
the form filed as an exhibit to the Registration Statement of which this
Prospectus forms a part, as of the date the Preferred Securities of such Trust
are initially issued. The Declaration will be qualified under the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"). Upon issuance of
the Preferred Securities, the purchasers thereof will own all of the Preferred
Securities. K N Energy will directly or indirectly acquire all of the Common
Securities, which will have an aggregate liquidation amount equal to 3% of the
total capital of the Trust. The Preferred Securities rank pari passu, and
payments will be made thereon on a pro rata basis, with the Common Securities,
except that upon the occurrence and during the continuance of a Declaration
Event of Default, the rights of the holders of the Common Securities to receive
payments of periodic distributions and payments upon liquidation, redemption and
otherwise will be subordinated to the rights of the holders of the Preferred
Securities. The Trust exists for the exclusive purposes of (i) issuing the Trust
Securities representing undivided beneficial interests in the assets of the
Trust, (ii) investing the gross proceeds of the Trust Securities in the Trust
Debentures and (iii) engaging in only those other activities necessary or
incidental thereto.
 
     The Trust's business and affairs will be conducted by the KN Trustees (as
defined below) and the administrators ("Administrators"), as set forth in the
Declaration. Pursuant to the Declaration, the number of KN Trustees will
initially be two. One trustee will be a financial institution that maintains its
principal place of business in the State of Delaware (the "Delaware Trustee").
The other trustee (the "Institutional Trustee" and, together with the Delaware
Trustee, the "KN Trustees") will be a financial institution that is unaffiliated
with K N Energy and will serve as institutional trustee under the Declaration
and as indenture trustee for the purposes of compliance with the provisions of
the Trust Indenture Act. Initially, Wilmington Trust Company, a Delaware banking
corporation, will be both the Delaware Trustee and the Institutional Trustee
until removed or replaced by the holder of the Common Securities (or in certain
circumstances the holders of a majority in liquidation amount of the Preferred
Securities). Wilmington Trust Company will act as trustee (the "Guarantee
Trustee") under the Guarantee and as Debenture Trustee (as defined herein) under
the Debenture Indenture (as defined herein). The Administrators will be three
individuals who are employees or officers of or affiliated with K N Energy and
will act as administrators with respect to the Trust. The Administrators will be
selected by the holders of a majority in liquidation amount of the Common
Securities. The Administrators will have only those ministerial duties set forth
in the Declaration with respect to accomplishing the purposes of the Trust and
are not intended to be trustees or fiduciaries with respect to the Trust or the
holders of Preferred Securities.
 
                                        5
<PAGE>   9
 
     The Institutional Trustee will hold title to the Trust Debentures for the
benefit of the holders of the Trust Securities, and the Institutional Trustee
will have the power to exercise all rights, powers and privileges under the
Debenture Indenture as the holder of the Trust Debentures. In addition, the
Institutional Trustee will maintain exclusive control of a segregated
non-interest bearing bank account (the "Property Account") to hold all payments
made in respect of the Trust Debentures for the benefit of the holders of the
Trust Securities. The Institutional Trustee will make payments of distributions
and payments on liquidation, redemption and otherwise to the holders of the
Trust Securities out of funds from the Property Account. The Guarantee Trustee
will hold the Guarantee for the benefit of the holders of the Preferred
Securities. K N Energy, as the direct or indirect holder of all the Common
Securities, will have the right to appoint, remove or replace any Administrator
and to increase or decrease the number of Administrators. Holders of the Common
Securities will have the right to replace the Institutional Trustee (or, upon
the occurrence and continuance of an event of default under the Declaration, the
holders of a majority in liquidation amount of the Preferred Securities),
provided that the successor Institutional Trustee shall be a corporation with
trust powers organized under the laws of the United States or any State thereof
with a combined capital and surplus of at least $500 million. Pursuant to the
Debenture Indenture, K N Energy, as borrower, will pay all fees and expenses
related to the Trust and the offering of the Trust Securities. See "Description
of the Trust Debentures -- Miscellaneous."
 
     The rights of the holders of the Preferred Securities, including economic
rights, rights to information and voting rights, are set forth in the
Declaration and the Delaware Business Trust Act (the "Trust Act"). The principal
place of business of the Trust is c/o K N Energy, Inc., 370 Van Gordon Street,
P.O. Box 281304, Lakewood, Colorado 80228-8304, and its telephone number is
(303) 989-1740.
 
                                USE OF PROCEEDS
 
     Except as may otherwise be described in the Prospectus Supplement relating
to an offering of Securities, the net proceeds from the sale of the Securities
(including Trust Debentures issued to the Trust in connection with the
investment by the Trust of all of the proceeds from the sale of the Preferred
Securities) offered pursuant to this Prospectus and such Prospectus Supplement
(the "Offered Securities") will be used by the Company to refinance indebtedness
incurred in connection with the Acquisition. The remainder of the net proceeds
will be used for general corporate purposes. Any specific allocation of the net
proceeds of an offering of Securities by the Company to a specific purpose will
be determined at the time of such offering and will be described in the related
Prospectus Supplement.
 
                      RATIOS OF EARNINGS TO FIXED CHARGES
 
     The following table sets forth the Company's consolidated ratios of
earnings to fixed charges for the periods shown.

     The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings are the sum of net income, taxes
and fixed charges. Fixed charges are interest, amortization of debt discount,
premium and expense, preferred stock dividends of a subsidiary, and the
estimated interest portion of rental charges. The allowance for borrowed funds
used during construction recognized for gas utility operations has been added to
fixed charges and is included in earnings.

                    DESCRIPTION OF THE PREFERRED SECURITIES
 
     The Trust may issue only one series of Preferred Securities having terms
described in the Prospectus Supplement relating thereto. The Declaration
authorizes the Administrators of the Trust to issue on behalf of the Trust one
series of Preferred Securities. The Declaration will be qualified as an
indenture under the Trust Indenture Act. The Preferred Securities will have such
terms, including distributions, redemption, voting, liquidation rights and such
other preferred, deferred or other special rights or such restrictions as shall
be set forth in the Declaration or made part of the Declaration Indenture by the
Trust Indenture Act or the Trust Act. Reference is made to any Prospectus
Supplement relating to the Preferred Securities of the Trust for specific terms,
including (i) the specific designation of the Preferred Securities, (ii) the
number of Preferred Securities, (iii) the annual distribution rate (or method of
calculation thereof) for Preferred Securities, the date or dates upon which such
distributions shall be payable and the record date or dates for the payment of
such distributions, (iv) whether distributions of Preferred Securities shall be
cumulative, and, in the case of Preferred Securities having such cumulative
distribution rights, the date or dates or method of determining the date or
dates from which distributions of Preferred Securities shall be cumulative, (v)
the amount or amounts which shall be paid out of the assets of the Trust to the
holders of Preferred Securities upon voluntary or involuntary dissolution,
winding-up or termination of the Trust, (vi) the obligation or right, if any, of
the Trust to purchase or redeem Preferred Securities and the price or prices at
which, the period or periods within which and the terms and conditions upon
which Preferred Securities shall or may be purchased or redeemed, in whole or in
part, pursuant to such obligation or right, (vii) the voting rights, if any, of
Preferred Securities in addition to those required by law, including the number
of votes per Preferred Security and any requirement for the approval by the
holders of Preferred Securities, as a condition to specified actions or
amendments to the Declaration, (viii) the terms and conditions, if any, upon
which Preferred Securities issued by the Trust may be converted into Common
Stock of the Company, including the conversion price per share and the
circumstances, if any, under which such conversion right will expire, (ix) the
terms and conditions, if any, upon which the Trust Debentures may be distributed
to holders of Trust Securities, (x) if applicable, any securities exchange upon

Guarantee." Certain United States federal income tax considerations applicable
to the offering of the Preferred Securities will be described in the Prospectus
Supplement relating thereto.
 
     In connection with the issuance of the Preferred Securities, the Trust will
issue Common Securities. The Declaration authorizes the Administrators of the
Trust to issue on behalf of the Trust the Common Securities having such terms
including distributions, redemption, voting, liquidation rights or such
restrictions as shall be set forth therein. The terms of the Common Securities
issued by the Trust will be substantially identical to the terms of the
Preferred Securities issued by the Trust and the Common Securities will rank
pari passu, and payments will be made thereon on a pro rata basis with the
Preferred Securities except that if an event of default under the Declaration (a
"Declaration Event of Default") occurs and is continuing, the rights of the
holders of the Common Securities to payments in respect of distributions and
payments upon liquidation, redemption and maturity will be subordinated to the
rights of the holders of the Preferred Securities. Except in certain limited
circumstances, the Common Securities issued by the Trust will also carry the
right to vote and to appoint, remove or replace any of the KN Trustees of the
Trust. All of the Common Securities of the Trust will be directly or indirectly
owned by the Company.
 
                      DESCRIPTION OF THE TRUST DEBENTURES
 
     The Trust Debentures are to be issued under an indenture, as supplemented
or amended from time to time (as so supplemented or amended, the "Debenture

which is filed as an exhibit to the Registration Statement of which this

Indenture. Such transfer or exchange will be effected upon the Security
Registrar or such transfer agent, as the case may be, being satisfied with the
documents of title and the identity of the person making the request. If the
applicable Prospectus Supplement refers to any transfer agents (in addition to
the Securities Registrar) initially designated by the Company with respect to
the Trust Debentures, the Company may at any time rescind the designation of any
such transfer agent or approve a change in the location through which any such
transfer agent acts, provided that the Company maintains a transfer agent in
each Place of Payment for the Trust Debentures. The Company may at any time
designate additional transfer agents with respect to the Trust Debentures.

     In the event of any redemption, neither the Company nor the Debenture
Trustee shall be required to (i) issue, register the transfer of or exchange of
the Trust Debentures during a period beginning at the opening of business 15
days before the day of selection for redemption of the Trust Debentures, and
ending at the close of business on the day of mailing of the relevant notice of
redemption or (ii) transfer or exchange any Trust Debentures so selected for
redemption, except, in the case of any Trust Debentures being redeemed in part,
any portion thereof not to be redeemed.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
     Unless otherwise set forth in the applicable Prospectus Supplement, the
Company shall have the right, at any time and from time to time during the term
of the Trust Debentures, to defer the payment of interest for such number of
consecutive interest payment periods as may be specified in the applicable
Prospectus Supplement, subject to the terms, conditions and covenants, if any,
specified in such Prospectus Supplement, provided that such Extension Period may
not extend beyond the Stated Maturity of the final installment of principal of
the Trust Debentures. Certain material U.S. federal income tax consequences and
special considerations applicable to the Trust Debentures will be described in
the applicable Prospectus Supplement.
 
CERTAIN COVENANTS
 
     The Debenture Indenture contains certain covenants regarding, among other
matters, corporate existence, payment of taxes and reports to holders of the
Trust Debentures. If and to the extent indicated in the applicable Prospectus
Supplement, these covenants may be removed or additional covenants added with
respect to the Trust Debentures.
 
DEBENTURE INDENTURE EVENTS OF DEFAULT
 
     The Debenture Indenture provides that any one or more of the following
described events, which has occurred and is continuing, constitutes a "Debenture
Indenture Event of Default" with respect to the Trust Debentures: (i) failure
for 30 days to pay interest on the Trust Debentures, including any compound
interest, in respect thereof or, any additional interest, if any, when due;
provided that a valid extension of an interest payment period will not
constitute a default in the payment of interest for this purpose; (ii) failure
to pay principal of or premium, if any, on the Trust Debentures when due whether
at maturity, upon redemption, by declaration or otherwise; (iii) failure to
observe or perform any other covenant contained in the Debenture Indenture for
90 days after notice to K N Energy by the Debenture Trustee or by the holders of
not less than 25% in aggregate outstanding principal amount of the Trust
Debentures; (iv) the dissolution, winding up or termination of the Trust, except
in connection with the distribution of Trust Debentures to the holders of
Preferred Securities in liquidation of the Trust upon the redemption of all
outstanding Preferred Securities or in connection with certain mergers,
consolidations or amalgamations permitted by the Declaration; or (v) certain
events in bankruptcy, insolvency or reorganization of K N Energy.
 
     If any Debenture Indenture Event of Default shall occur and be continuing,
the Debenture Trustee or the holders of not less than 25% in aggregate principal
amount of the outstanding Trust Debentures may declare the principal of and
interest on the Trust Debentures due and payable immediately; provided, that,
after such acceleration, but before a judgment or decree based on acceleration,
the holders of a majority in aggregate principal amount of outstanding Trust
Debentures may, under certain circumstances, rescind and annul such acceleration
if all Debenture Indenture Events of Default, other than the nonpayment of
accelerated principal, have been cured or waived as provided in the Debenture
Indenture.
 
     A default under any other indebtedness of K N Energy would not constitute a
Debenture Indenture Event of Default under the Trust Debentures.
 
     Subject to the provisions of the Debenture Indenture relating to the duties
of the Debenture Trustee in case a Debenture Indenture Event of Default occurs
and is continuing, the Debenture Trustee will be under no obligation to exercise
any of its rights or powers under the Debenture Indenture at the request or
direction of any holders of Trust Debentures, unless such holders shall have
offered to the Debenture Trustee reasonable indemnity. Subject to such
provisions for the indemnification of the Debenture Trustee, the holders of a
 
                                       10
<PAGE>   14
 
majority in aggregate principal amount of the outstanding Trust Debentures will
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Debenture Trustee, or exercising any trust or
power conferred on the Debenture Trustee.
 
     No holder of any Trust Debentures will have any right to institute any
proceeding with respect to the Debenture Indenture or for any remedy thereunder,
unless such holder shall have previously given to the Debenture Trustee written
notice of a continuing Debenture Indenture Event of Default and, if the
Institutional Trustee is not the sole holder of Trust Debentures, unless the
holders of at least 25% in aggregate principal amount of the outstanding Trust
Debentures shall also have made written request, and offered reasonable
indemnity, to the Debenture Trustee to institute such proceeding as Debenture
Trustee, and the Debenture Trustee shall not have received from the holders of a
majority in aggregate principal amount of the outstanding Trust Debentures a
direction inconsistent with such request. However, such limitations do not apply
to a suit instituted by a holder of a Trust Debenture for enforcement of payment
of the principal of or interest on such Trust Debenture on or after the
respective due dates expressed in such Trust Debenture.
 
     The Debenture Indenture contains provisions permitting the holders of a
majority in aggregate principal amount of the Trust Debentures, on behalf of all
of the holders of the Trust Debentures, to waive any past default in the
performance of any of the covenants contained in the Debenture Indenture, except
a default in the payment of principal or interest on any of the Trust
Debentures.
 
MODIFICATIONS AND AMENDMENTS OF THE DEBENTURE INDENTURE
 
     The Debenture Indenture contains provisions permitting K N Energy and the
Debenture Trustee, with the consent of the holders of not less than a majority
in aggregate principal amount of the outstanding Trust Debentures, to modify the
Debenture Indenture or the rights of the holders of Trust Debentures; provided,
however, that no such modification may, without the consent of the holder of
each outstanding Trust Debenture affected thereby, (i) extend the Stated
Maturity of the Trust Debentures or reduce the principal amount thereof, or
reduce the rate or extend the time for payment of interest thereon, or reduce
any premium payable upon the redemption thereof, or adversely affect the
subordination provisions of the Debenture Indenture, or (ii) reduce the
percentage in aggregate principal amount of outstanding Trust Debentures, the
holders of which are required to consent to any such supplemental indenture.
 
     In addition, K N Energy and the Debenture Trustee may execute, without the
consent of any holder of Trust Debentures, any supplemental indenture (i) to
cure any ambiguities, (ii) to comply with the Trust Indenture Act and (iii) for
certain other customary purposes.
 
SATISFACTION AND DISCHARGE; DEFEASANCE
 
     Unless otherwise specified in the applicable Prospectus Supplement, when,
among other things, all Trust Debentures not previously delivered to the
Debenture Trustee for cancellation (i) have become due and payable or (ii) will
become due and payable at their Stated Maturity within one year, and the Company
deposits or causes to be deposited with the Debenture Trustee, as trust funds in
trust for the purpose, an amount in the currency or currencies in which the
Trust Debentures are payable sufficient to pay and discharge the entire
indebtedness on the Trust Debentures not previously delivered to the Debenture
Trustee for cancellation, for the principal (and premium, if any) and interest
to the date of the deposit or to the Stated Maturity, as the case may be, then
the Debenture Indenture will cease to be of further effect (except as to the
Company's obligations to pay all other sums due pursuant to the Debenture
Indenture and to provide the officers' certificates and opinions of counsel
described therein), and the Company will be deemed to have satisfied and
discharged the Debenture Indenture.
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Company may elect either (a) to terminate (and be deemed to have satisfied) all
its obligations with respect to any series of Trust Debentures (except for the
obligations to register the transfer or exchange of such Trust Debentures, to
replace mutilated, destroyed, lost or stolen Trust Debentures, to maintain an
office or agency in respect of the Trust Debentures, to compensate and indemnify
the Debenture Trustee ("defeasance")) or (b) to be released from its obligations
with respect to certain covenants, ("covenant defeasance"), upon the deposit
with the
 
                                       11
<PAGE>   15
 
Debenture Trustee, in trust for such purpose, of money and/or U.S. Government
Obligations (as defined in the Debenture Indenture) which through the payment of
principal and interest in accordance with their terms will provide money, in an
amount sufficient (in the opinion of a nationally recognized firm of independent
public accountants) to pay principal of, interest on and any other amounts
payable in respect of the outstanding Trust Debentures. Such a trust may be
established only if, among other things, the Company has delivered to the
Debenture Trustee an opinion of counsel (as specified in the Debenture
Indenture) with regard to certain matters, including an opinion to the effect
that the holders of such Trust Debentures will not recognize income, gain or
loss for federal income tax purposes as a result of such deposit and discharge
and will be subject to federal income tax on the same amounts and in the same
manner and at the same times as would have been the case if such deposit and
defeasance or covenant defeasance, as the case may be, had not occurred.
 
INFORMATION CONCERNING THE DEBENTURE TRUSTEE
 
     The Debenture Trustee, prior to default, undertakes to perform only such
duties as are specifically set forth in the Debenture Indenture and, after
default, shall exercise the same degree of care as a prudent individual would
exercise in the conduct of his or her own affairs. Subject to such provision,
the Debenture Trustee is under no obligation to exercise any of the powers
vested in it by the Debenture Indenture at the request of any holder of Trust
Debentures, unless offered reasonable indemnity by such holder against the
costs, expenses and liabilities that might be incurred thereby. The Debenture
Trustee is not required to expend or risk its own funds or otherwise incur
personal financial liability in the performance of its duties if the Debenture
Trustee reasonably believes that repayment or adequate indemnity is not
reasonably assured to it.
 
     The Debenture Indenture also contains limitations on the right of the
Debenture Trustee, as a creditor of K N Energy, to obtain payment of claims in
certain cases or to realize on certain property received in respect of any such
claim as security or otherwise. In addition, the Debenture Trustee may be deemed
to have a conflicting interest and may be required to resign as Debenture
Trustee if at the time of a default under the Debenture Indenture it is a
creditor of K N Energy. K N Energy may from time to time maintain deposit
accounts and conduct its banking transactions with the Debenture Trustee in the
ordinary course of business.
 
     Wilmington Trust Company is also the trustee under the indenture relating
to the 1997 Subordinated Trust Debentures. Pursuant to the Trust Indenture Act,
should a default occur with respect to either the 1997 Trust Subordinated
Debentures or the Trust Debentures, then Wilmington Trust Company would be
required to resign as trustee under one of the indentures within 90 days of such
default, unless such default were cured, duly waived or otherwise eliminated.
 
GOVERNING LAW
 
     The Debenture Indenture and the Trust Debentures will be governed by, and
construed in accordance with, the laws of the State of New York.
 
MISCELLANEOUS
 
     The Debenture Indenture will provide that K N Energy will pay all fees and
expenses related to (i) the offering of the Trust Securities and the Trust
Debentures, (ii) the organization, maintenance and dissolution of the Trust,
(iii) the retention of the K N Trustees and Administrators and (iv) the
enforcement by the Institutional Trustee of the rights of the holders of the
Preferred Securities.
 
     K N Energy will have the right at all times to assign any of its respective
rights or obligations under the Debenture Indenture to a direct or indirect
wholly-owned subsidiary of K N Energy; provided, that, in the event of any such
assignment, K N Energy will remain liable for all of their respective
obligations. Subject to the foregoing, the Debenture Indenture will be binding
upon and inure to the benefit of the parties thereto and their respective
successors and assigns. The Debenture Indenture provides that it may not
otherwise be assigned by the parties thereto.

                          DESCRIPTION OF THE GUARANTEE
 
     Set forth below is a summary of information concerning the Guarantee, which
will be executed and delivered by K N Energy for the benefit of the holders from
time to time of Preferred Securities. The Guarantee will be qualified under the
Trust Indenture Act. Wilmington Trust Company, as the Guarantee Trustee, will
hold the Guarantee for the benefit of the holders of the Preferred Securities.
The following summary is not necessarily complete, and reference is hereby made
to the copy of the form of the Guarantee (including the definitions therein of
certain terms), which is filed as an exhibit to the Registration Statement of
which this Prospectus forms a part, and to the Trust Indenture Act. Whenever
particular defined terms of the Guarantee are referred to in this Prospectus,
such defined terms are incorporated herein by reference.
 
GENERAL
 
     Pursuant to and to the extent set forth in the Guarantee, unless otherwise
specified in the applicable Prospectus Supplement, K N Energy will agree to pay
in full to the holders of the Preferred Securities (except to the extent paid by
the Trust), as and when due, regardless of any defense, right of set off or
counterclaim that the Trust may have or assert, the following payments (the
"Guarantee Payments"), without duplication: (i) any accumulated and unpaid
distributions that are required to be paid on the Preferred Securities to the
extent the Trust has funds available therefor, (ii) the Redemption Price, plus
accumulated and unpaid distributions, with respect to any Preferred Securities
called for redemption by the Trust, to the extent the Trust has funds available
therefor and (iii) upon a voluntary or involuntary liquidation, dissolution,
winding-up or termination of the Trust (other than in connection with the
distribution of Trust Debentures to the holders of Trust Securities or the
redemption of all the Preferred Securities), the lesser of (a) the aggregate of
the liquidation amount and all accumulated and unpaid distributions on the
Preferred Securities to the date of payment to the extent the Trust has funds
available therefor and (b) the amount of assets of the Trust remaining available
for distribution to holders of Preferred Securities upon the liquidation of the
Trust. The holders of a majority in 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 Guarantee Trustee or to direct the
exercise of any trust or power conferred upon the Guarantee Trustee under the
Guarantee. If the Guarantee Trustee fails to enforce the Guarantee, any holder
of Preferred Securities may directly institute a legal proceeding against K N
Energy to enforce the obligations of K N Energy under the Guarantee without
first instituting a legal proceeding against the Trust, the Guarantee Trustee or
any other person or entity. If K N Energy were to default on its obligation to
pay amounts payable on the Trust Debentures, the Trust would lack available
funds for the payment of distributions or amounts payable on redemption of the
Preferred Securities or otherwise, and in such event holders of the Preferred
Securities would not be able to rely upon the Guarantee for payment of such
amounts. Instead, a holder of the Preferred Securities would be required to rely
on the enforcement (1) by the Institutional Trustee of its rights, as registered
holder of the Trust Debentures, against K N Energy pursuant to the terms of the
Trust Debentures or (2) by such holder of Preferred Securities of its right
against K N Energy to enforce payment on the Trust Debentures. See "Description
of the Trust Debentures." The Declaration provides that each holder of Preferred
Securities, by acceptance thereof, if any, agrees to the provisions of the
Guarantee, including the subordination provisions thereof, if any, and the
Debenture Indenture.
 
     The Guarantee will not apply to any payment of distributions or Redemption
Price, or to payments upon the dissolution, winding-up or termination of the
Trust, except to the extent the Trust shall have funds available therefor. If K
N Energy does not make interest payments on the Trust Debentures, the Trust will
not pay distributions on the Preferred Securities and will not have funds
available therefor. See "Description of the Trust Debentures." Unless otherwise
set forth in the applicable Prospectus Supplement, the Guarantee, when taken
together with K N Energy's obligations under the Trust Debentures, the Debenture
Indenture and the Declaration, including its obligations under the Debenture
Indenture to pay costs, expenses, debts and liabilities of the Trust (other than
with respect to the Trust Securities) will provide a full and unconditional
guarantee on a senior unsecured basis by K N Energy of payments due on the
Preferred Securities.
 
     K N Energy has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Trust with respect to the Common Securities
(the "Common Securities Guarantee") to the same extent as
 
                                       13
<PAGE>   17
 
the Guarantee, except that upon the occurrence and during the continuation of a
Declaration Event of Default, holders of Preferred Securities shall have
priority over holders of Common Securities with respect to distributions and
payments on liquidation, redemption or otherwise.
 
CERTAIN COVENANTS OF K N ENERGY
 
     In the Guarantee, K N Energy will covenant that, so long as any Preferred
Securities remain outstanding, if (i) K N Energy has exercised its option to
defer interest payments on the Trust Debentures by extending the interest
payment period and such extension shall be continuing, (ii) K N Energy shall be
in default with respect to its payment or other obligations under the Guarantee
or (iii) there shall have occurred and be continuing any event that, with the
giving of notice, would constitute a Declaration Event of Default, then K N
Energy (a) shall not declare or pay dividends on, make distributions with
respect to, or redeem, purchase or acquire, or make a liquidation payment with
respect to, any of its capital stock (other than (1) purchases or acquisitions
of shares of K N Energy Common Stock in connection with satisfaction by K N
Energy or any of its subsidiaries of their respective obligations under any
shares of, or options, warrants or rights to subscribe for the purchase of
shares of benefit plans for directors, officers, agents or employees or the
Company's dividend reinvestment or director, officer, agent or employee stock
purchase plans, (2) as a result of a reclassification of K N Energy's capital
stock or the exchange or conversion of one class or series of K N Energy's
capital stock for another class or series of capital stock, (3) the purchase of
fractional interests in shares of K N Energy's capital stock pursuant to the
conversion or exchange provisions of such K N Energy capital stock or the
security being convened or exchanged for K N Energy capital stock, (4) dividends
and distributions in shares of, or options, warrants or rights to subscribe for
the purchase of shares of capital stock of the Company and (5) any declaration
of a dividend in connection with the implementation or extension of a
stockholders' rights plan, or the issuance of stock under any such plan
(including the existing such plan) in the future, or the redemption or
repurchase of any such rights pursuant thereto)), (b) shall not make any payment
of interest, principal or premium, if any, on, or repay, repurchase or redeem,
any debt securities issued by K N Energy that rank pari passu with or junior to
the Trust Debentures and (c) shall not make any guarantee payments with respect
to the foregoing (other than payments pursuant to the 1997 Guarantee (as defined
herein) or the Guarantee or other guarantees of similarly situated trusts or
other financing vehicles of the Company).
 
AMENDMENTS AND ASSIGNMENT
 
     Except with respect to any changes that do not materially adversely affect
the rights of holders of Preferred Securities (in which case no vote will be
required) the Guarantee may be amended only with the prior approval of the
holders of at least a majority in liquidation amount of all the outstanding
Preferred Securities. The manner of obtaining any such approval of holders of
the Preferred Securities will be as set forth in the applicable Prospectus
Supplement. All guarantees and agreements contained in the Guarantee shall bind
the successors, assigns, receivers, trustees and representatives of K N Energy
and shall inure to the benefit of the holders of the Preferred Securities then
outstanding. Except in certain circumstances, K N Energy may not assign its
rights or delegate its obligations under the Guarantee without the prior
approval of the holders of at least a majority in liquidation amount of the
Preferred Securities then outstanding.
 
TERMINATION OF THE GUARANTEE
 
     The Guarantee will terminate as to each holder of Preferred Securities upon
(i) full payment of the Redemption Price and accumulated and unpaid
distributions with respect to all Preferred Securities, (ii) upon distribution
of the Trust Debentures held by the Trust to the holders of the Preferred
Securities or (iii) upon liquidation of the Trust and will terminate completely
upon full payment of the amounts payable in accordance with the Declaration.
 
EVENTS OF DEFAULT
 
     An event of default under the Guarantee will occur upon the failure of K N
Energy to perform any of its payment or other obligations thereunder.
 
                                       14
<PAGE>   18
 
     The holders of a majority in liquidation amount of Preferred Securities
relating to the Guarantee have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under the Preferred Securities. If the
Guarantee Trustee fails to enforce the Guarantee, any holder of Preferred
Securities relating to such Guarantee may institute a legal proceeding directly
against K N Energy to enforce the Guarantee Trustee's rights under the
Guarantee, without first instituting a legal proceeding against the Trust, the
Guarantee Trustee or any other person or entity. Notwithstanding the foregoing,
if K N Energy has failed to make a guarantee payment, a holder of Preferred
Securities may directly institute a proceeding against K N Energy for
enforcement of the Guarantee for such payment. K N Energy waives any right or
remedy to require that any action be brought first against the Trust or any
other person or entity before proceeding directly against K N Energy.
 
STATUS OF THE GUARANTEE
 
     Unless otherwise set forth in the applicable Prospectus Supplement, the
Guarantee will constitute an unsecured obligation of K N Energy and will rank
(i) pari passu in right of payment to all other senior unsecured obligations of
K N Energy, (ii) senior to the most senior preferred or preference stock now or
hereafter issued by K N Energy and with any guarantee now or hereafter entered
into by K N Energy in respect of any preferred or preference stock of any
affiliate of K N Energy, and (iii) senior to K N Energy Common Stock and the
1997 Guarantee (as defined herein). The terms of the Preferred Securities
provide that each holder of Preferred Securities issued by the Trust by
acceptance thereof agrees to the other terms of the Guarantee relating thereto.
 
     The Guarantee will constitute a guarantee of payment and not of collection
(that is, the guaranteed party may institute a legal proceeding directly against
the guarantor to enforce its rights under the guarantee without instituting a
legal proceeding against any other person or entity).
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, prior to the occurrence of a default with respect to
the Guarantee, undertakes to perform only such duties as are specifically set
forth in the Guarantee and, after default with respect to the Guarantee, shall
exercise the same degree of care as a prudent man would exercise in the conduct
of his own affairs. Subject to such provision, the Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by the Guarantee at the
request of any holder of Preferred Securities unless it is offered reasonable
indemnity against the costs, expenses and liabilities that might be incurred
thereby.
 
     Wilmington Trust Company is also the trustee under the 1997 Guarantee.
Pursuant to the Trust Indenture Act, should a default occur with respect to
either the 1997 Guarantee, or the Guarantee, then Wilmington Trust Company would
be required to resign as trustee under one of the guarantees within 90 days of
such default, unless such default were cured, duly waived or otherwise
eliminated.
 
GOVERNING LAW
 
     The Guarantee will be governed by, and construed in accordance with, the
laws of the State of New York.
 
                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
                     THE TRUST DEBENTURES AND THE GUARANTEE
 
     As set forth in the Declaration, the sole purpose of the Trust is to issue
the Trust Securities evidencing undivided beneficial ownership interests in the
assets of the Trust, and to invest the proceeds from such issuance and sale in
the Trust Debentures.
 
     As long as payments of interest and other payments are made when due on the
Trust Debentures, such payments will be sufficient to cover distributions and
payments due on the Trust Securities because of the following factors: (i) the
aggregate principal amount of Trust Debentures will be equal to the sum of the
aggregate stated liquidation amount of the Trust Securities; (ii) the interest
rate and the interest and other
 
                                       15
<PAGE>   19
 
payment dates on the Trust Debentures will match the distribution rate and
distribution and other payment dates for the Preferred Securities; (iii)
pursuant to the Debenture Indenture, K N Energy, as borrower, shall pay, and the
Trust shall not be obligated to pay, directly or indirectly, all costs,
expenses, debts and obligations of the Trust (other than with respect to the
Trust Securities); and (iv) the Declaration further provides that the K N
Trustees shall 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 therefor are available) and
other payments due on the Preferred Securities (to the extent funds therefor are
available) are guaranteed by K N Energy as and to the extent set forth under
"Description of the Guarantee." If K N Energy does not make interest payments on
the Trust Debentures purchased by the Trust, it is expected that the Trust will
not have sufficient funds to pay distributions on the Preferred Securities. The
Guarantee is a full guarantee on a subordinated basis with respect to the
Preferred Securities issued by the Trust from the time of its issuance but does
not apply to any payment of distributions unless and until the Trust has
sufficient funds for the payment of such distributions. The Guarantee covers the
payment of distributions and other payments on the Preferred Securities only if
and to the extent that K N Energy has made a payment of interest or principal on
the Trust Debentures held by the Trust as its sole asset. The Guarantee, when
taken together with K N Energy's obligations under the Trust Debentures, the
Debenture Indenture and the Declaration, including its obligations to pay costs,
expenses, debts and liabilities of the Trust (other than with respect to the
Trust Securities), provides a full and unconditional guarantee on a subordinated
basis of amounts payable on the Preferred Securities.
 
     Notwithstanding anything to the contrary in the Debenture Indenture, the
Company has the right to set-off any payment it is otherwise required to make
thereunder with and to the extent the Company has theretofore made, or is
concurrently on the date of such payment making, a payment under the Guarantee.
 
     If the Guarantee Trustee fails to enforce the Guarantee, a holder of any
Preferred Security may institute a legal proceeding directly against the Company
to enforce its rights under the Guarantee without first instituting a legal
proceeding against the Guarantee Trustee, the Trust or any other person or
entity.
 
     The Trust's Preferred Securities evidence undivided beneficial ownership
interests in the assets of the Trust, and the Trust exists for the sole purpose
of issuing the Preferred Securities and Common Securities and investing the
proceeds thereof in Trust Debentures. A principal difference between the rights
of a holder of a Preferred Security and a holder of a Trust Debenture is that a
holder of a Trust Debenture will accrue, and (subject to the permissible
extension of the interest period) is entitled to receive, interest on the
principal amount of Trust Debentures held, while a holder of Preferred
Securities is only entitled to receive distributions if and to the extent the
Trust has funds available for the payment of such distributions.
 
     Upon any voluntary or involuntary dissolution of the Trust involving the
liquidation of the Trust Debentures, the holders of Preferred Securities of the
Trust will be entitled to receive, out of assets held by the Trust, the
Liquidation Distribution in cash. See "Description of the Preferred Securities."
Upon any voluntary or involuntary liquidation or bankruptcy of the Company, the
Institutional Trustee as holder of the Trust Debentures would be entitled to
receive payment in full of principal and interest, before any stockholders of
the Company receive payments or distributions.
 
                       DESCRIPTION OF THE DEBT SECURITIES
 
     The Debt Securities will constitute either senior or subordinated debt of
the Company and will be issued, in the case of Debt Securities that will be
senior debt ("Senior Debt Securities"), under an Indenture dated as of November
20, 1993 (the "Senior Debt Indenture"), between the Company and First Trust
National Association, as successor trustee, and, in the case of Debt Securities
that will be subordinated debt ("Subordinated Debt Securities"), under a
Subordinated Indenture dated as of May 15, 1996 (the "Subordinated Debt
Indenture"), between the Company and First Trust National Association, as
trustee. The Senior Debt Indenture and the Subordinated Debt Indenture are
sometimes hereinafter referred to individually as the "Debt Indenture" and
collectively as the "Debt Indentures." First Trust National Association (and any
successor thereto as trustee under the Debt Indentures) is hereinafter referred
to as the "Debt Trustee."

The Debt Indentures are incorporated by reference in the Registration Statement.
The following summaries of certain provisions of the Debt Indentures and the
Debt Securities do not purport to be complete and such summaries are subject to
the detailed provisions of the applicable Debt Indenture to which reference is
hereby made for a full description of such provisions, including the definition
of certain terms used herein. Section references in parentheses below are to
sections in both Debt Indentures unless otherwise indicated. Wherever particular
sections or defined terms of the applicable Debt Indenture are referred to, such
sections or defined terms are incorporated herein by reference as part of the
statement made, and the statement is qualified in its entirety by such
reference. The Debt Indentures are substantially identical, except for certain
covenants of the Company and provisions relating to subordination and
conversion.
 
     The Debt Securities may be issued from time to time in one or more series.
The following description of the Debt Securities sets forth certain general
terms and provisions of the Debt Securities of all series. The particular terms
of each series of Debt Securities offered by any Prospectus Supplement (the
"Offered Debt Securities") will be described therein.
 
     The Company's Trust Debentures are separately described in this Prospectus
under the caption "Description of the Trust Debentures."
 
PROVISIONS APPLICABLE TO BOTH SENIOR AND SUBORDINATED DEBT SECURITIES
 
     General.  The Debt Securities will be unsecured senior or subordinated
obligations of the Company and may be issued from time to time in one or more
series. The Debt Indentures do not limit the amount of Debt Securities,
debentures, notes or other types of indebtedness that may be issued by the
Company or any of its subsidiaries nor do they restrict transactions between the
Company and its affiliates or the payment of dividends or other distributions by
the Company to its stockholders. The rights of the Company's creditors,
including holders of Debt Securities, will be limited to the assets of the
Company and will not be an obligation of any of its Subsidiaries. In addition,
other than as may be set forth in any Prospectus Supplement, the Debt Indentures
do not and the Debt Securities will not contain any covenants or other
provisions that are intended to afford holders of the Debt Securities special
protection in the event of either a change of control of the Company or a highly
leveraged transaction by the Company.
 
     Reference is made to the Prospectus Supplement for the following terms of
and information relating to the Offered Debt Securities (to the extent such
terms are applicable to such Offered Debt Securities): (i) the title of the
Offered Debt Securities; (ii) classification as either Senior Debt Securities or
Subordinated Debt Securities; (iii) whether the Offered Debt Securities that
constitute Subordinated Debt Securities are convertible into Common Stock and,
if so, the terms and conditions upon which such conversion will be effected
including the initial conversion price or conversion rate and any adjustments
thereto in addition to or different from those described herein, the conversion
period and other conversion provisions in addition to or in lieu of those
described herein; (iv) any limit on the aggregate principal amount of the
Offered Debt Securities; (v) whether the Offered Debt Securities are to be
issuable as Registered Securities or Bearer Securities or both, whether any of
the Offered Debt Securities are to be issuable initially in temporary global
form and whether any of the Offered Debt Securities are to be in permanent
global form; (vi) the price or prices (expressed as a percentage of the
aggregate principal amount thereof) at which the Offered Debt Securities will be
issued; (vii) the date or dates on which the Offered Debt Securities will
mature; (viii) the rate or rates per annum (or the method by which such will be
determined) at which the Offered Debt Securities will bear interest, if any, and
the date from which any such interest will accrue; (ix) the Interest Payment
Dates on which any such interest on the Offered Debt Securities will be payable,
the Regular Record Date for any interest payable on any Offered Debt Securities
which are Registered Securities on any Interest Payment Date and the extent to
which, or the manner in which, any interest payable on a temporary global
Offered Debt Security on an Interest Payment Date will be paid; (x) any
mandatory or optional sinking fund or analogous provisions; (xi) each office or
agency where, subject to the terms of the Debt Indentures as described below
under "Payment and Paying Agents", the principal of and any premium and interest
on the Offered Debt Securities will be payable and each office or agency where,
subject to the terms of the Debt Indentures as described below under "-- Form,
Exchange, Registration and Transfer", the Offered Debt Securities may be
presented for registration of transfer or exchange; (xii) the right of the
Company to redeem the Offered Debt
 
                                       17
<PAGE>   21
 
Securities at its option and the period or periods, if any, within which and the
price or prices at which the Offered Debt Securities may, pursuant to any
optional or mandatory redemption provisions, be redeemed, in whole or in part,
and the other detailed terms and provisions of any such optional or mandatory
redemption; (xiii) the denominations in which any Offered Debt Securities which
are Registered Securities will be issuable, if other than denominations of
$1,000 and any integral multiple thereof, and the denomination or denominations
in which any Offered Debt Securities which are Bearer Securities will be
issuable, if other than the denomination of $5,000; (xiv) the currency or
currencies (including composite currencies) in which payment of principal of and
any premium and interest on the Offered Debt Securities is payable; (xv) any
index used to determine the amount of payments of principal of and any premium
and interest on the Offered Debt Securities; (xvi) information with respect to
book-entry procedures, if any; (xvii) any applicable United States federal
income tax consequences; and (xviii) any other terms of the Offered Debt
Securities not inconsistent with the provisions of the Debt Indentures. (Section
301) Any such Prospectus Supplement will also describe any special provisions
for the payment of additional amounts with respect to the Offered Debt
Securities.
 
     Debt Securities may be issued as Original Issue Discount Securities. An
Original Issue Discount Security is a Debt Security, including any Zero-Coupon
Security, which is issued at a price lower than the amount payable upon the
Stated Maturity thereof and which provides that upon redemption or acceleration
of the maturity thereof an amount less than the amount payable upon the Stated
Maturity thereof and determined in accordance with the terms of such Debt
Security shall become due and payable. Special United States federal income tax
considerations applicable to Debt Securities issued at an original issue
discount, including Original Issue Discount Securities, and special United
States tax considerations and other terms and restrictions applicable to any
Debt Securities which are issued in bearer form, offered exclusively to United
States Aliens or denominated in other than United States dollars, will be set
forth in a Prospectus Supplement relating thereto.
 
     Form, Exchange, Registration and Transfer.  Debt Securities of a series may
be issuable in definitive form solely as Registered Securities, solely as Bearer
Securities or as both Registered Securities and Bearer Securities. Unless
otherwise indicated in an applicable Prospectus Supplement, Bearer Securities
will have interest coupons attached. (Section 201) The Debt Indentures also
provide that Debt Securities of a series may be issuable in temporary or
permanent global form. (Section 201)
 
     Registered Securities of any series will be exchangeable for other
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor. In addition, if Debt Securities of
any series are issuable as both Registered Securities and Bearer Securities, at
the option of the Holder, and subject to the terms of the applicable Debt
Indenture, Bearer Securities (with all unmatured coupons, except as provided
below, and all matured coupons in default) of such series will be exchangeable
for Registered Securities of the same series of any authorized denominations and
of a like aggregate principal amount and tenor. Bearer Securities surrendered in
exchange for Registered Securities between a Regular Record Date or a Special
Record Date and the relevant date for payment of interest shall be surrendered
without the coupon relating to such date for payment of interest, and interest
accrued as of such date will not be payable in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such coupon when due in accordance with the terms of the
applicable Debt Indenture. Bearer Securities will not be issued in exchange for
Registered Securities. (Section 305)
 
     Debt Securities may be presented for exchange as provided above, and
Registered Securities may be presented for registration of transfer (with the
form of transfer endorsed thereon duly executed), at the office of the Security
Registrar or at the office of any transfer agent designated by the Company for
such purpose with respect to any series of Debt Securities and referred to in an
applicable Prospectus Supplement, without service charge and upon payment of any
taxes and other governmental charges as described in the Debt Indentures. Such
transfer or exchange will be effected upon the Security Registrar or such
transfer agent, as the case may be, being satisfied with the documents of title
and identity of the person making the request. The Debt Trustee will serve
initially as Security Registrar. (Section 305) If a Prospectus Supplement refers
to any transfer agents (in addition to the Security Registrar) initially
designated by the Company with respect to any series of Debt Securities, the
Company may at any time rescind the designation of any such transfer agent or
 
                                       18
<PAGE>   22
 
approve a change in the location through which any such transfer agent acts,
except that, if Debt Securities of a series are issuable solely as Registered
Securities, the Company will be required to maintain a transfer agent in each
Place of Payment for such series and, if Debt Securities of a series are also
issuable as Bearer Securities, the Company will be required to maintain (in
addition to the Security Registrar) a transfer agent in a Place of Payment for
such series located outside the United States. The Company may at any time
designate additional transfer agents with respect to any series of Debt
Securities. (Section 1002)
 
     In the event of any redemption in part, the Company shall not be required
to (i) issue, register the transfer of or exchange Debt Securities of any series
during a period beginning at the opening of business 15 days prior to the
selection of Debt Securities of that series for redemption and ending on the
close of business on (A) if Debt Securities of the series are issuable only as
Registered Securities, the day of mailing of the relevant notice of redemption
and (B) if Debt Securities of the series are issuable as Bearer Securities, the
date of the first publication of the relevant notice of redemption or, if
Securities of the series are also issuable as Registered Securities and there is
no publication, the mailing of the relevant notice of redemption; (ii) register
the transfer of or exchange any Registered Security, or portion thereof, called
for redemption, except the unredeemed portion of any Registered Security being
redeemed in part; or (iii) exchange any Bearer Security called for redemption,
except to exchange such Bearer Security for a Registered Security of that series
and like tenor which is immediately surrendered for redemption. (Section 305)
 
     Payment and Paying Agents.  Unless otherwise indicated in an applicable
Prospectus Supplement, payment of principal of and any premium and interest on
Bearer Securities will be payable, subject to any applicable laws and
regulations, at the offices of such Paying Agents outside the United States as
the Company may designate from time to time, in the manner indicated in such
Prospectus Supplement. (Section 1002) Unless otherwise indicated in an
applicable Prospectus Supplement, payment of interest on Bearer Securities on
any Interest Payment Date will be made only against surrender to the Paying
Agent of the coupon relating to such Interest Payment Date. (Section 1001) No
payment with respect to any Bearer Security will be made at any office or agency
of the Company in the United States or by check mailed to any address in the
United States or by transfer to any account maintained with a bank located in
the United States. Notwithstanding the foregoing, payments of principal of and
any premium and interest on Bearer Securities denominated and payable in U.S.
dollars will be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment of the full amount
thereof in U.S. dollars at all offices or agencies outside the United States is
illegal or effectively precluded by exchange controls or other similar
restrictions. (Section 1002)
 
     Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of and any premium and interest on Registered Securities will be
made at the office of such Paying Agent or Paying Agents as the Company may
designate from time to time, except that at the option of the Company payment of
any interest may be made by check mailed on or before the due date to the
address of the Person entitled thereto as such address shall appear in the
Security Register. (Sections 307, 1002) Unless otherwise indicated in an
applicable Prospectus Supplement, payment of any installment of interest on
Registered Securities will be made to the Person in whose name such Registered
Security is registered at the close of business on the Regular Record Date for
such interest. (Section 307)
 
     Unless otherwise indicated in an applicable Prospectus Supplement, the Debt
Trustee, at its corporate trust office in Chicago, Illinois, will act as Paying
Agent for payments with respect to Debt Securities which are issuable solely as
Registered Securities and the Company will maintain a Paying Agent outside the
United States for payments with respect to Debt Securities (subject to
limitations described above in the case of Bearer Securities) which are issuable
solely as Bearer Securities or as both Registered Securities and Bearer
Securities. Any Paying Agents outside the United States and any other Paying
Agents in the United States initially designated by Company for the Debt
Securities will be named in an applicable Prospectus Supplement. The Company may
at any time designate additional Paying Agents or rescind the designation of any
Paying Agent or approve a change in the office through which any Paying Agent
acts, except that, if Debt Securities of a series are issuable solely as
Registered Securities, the Company will be required to maintain a Paying Agent
in each Place of Payment for such series and, if Debt Securities of a series are
issuable as Bearer Securities, the Company will be required to maintain (i) a
Paying Agent in the Borough of Manhattan, The
 
                                       19
<PAGE>   23
 
City of New York for principal payments with respect to any Registered
Securities of the series (and for payments with respect to Bearer Securities of
the series in the circumstances described above, but not otherwise), and (ii) a
Paying Agent in a Place of Payment located outside the United States where Debt
Securities of such series and any coupons appertaining thereto may be presented
and surrendered for payment. (Section 1002)
 
     All monies paid by the Company to a Paying Agent for the payment of
principal of and any premium or interest on any Debt Security which remain
unclaimed at the end of two years after such principal, premium or interest
shall have become due and payable will (subject to applicable escheat laws) be
repaid to the Company, and the Holder of such Debt Security or any coupon will
thereafter look only to the Company for payment thereof. (Section 1003)
 
     Global Debt Securities.  Debt Securities of a series may be issued in whole
or in part in the form of one or more global Debt Securities that will be
deposited with, or on behalf of, a depository identified in the Prospectus
Supplement relating to such series. Global Debt Securities may be issued in
either registered or bearer form and in either temporary or permanent form.
(Section 203) Unless and until it is exchanged in whole or in part for the
individual Debt Securities represented thereby, a global Debt Security may not
be transferred except as a whole by the depository for such global Debt Security
to a nominee of such depository or by a nominee of such depository to such
depository or another nominee of such depository or by the depository or any
nominee to a successor depository or any nominee of such successor.
 
     The specific terms of the depository arrangement with respect to a series
of Debt Securities and certain limitations and restrictions relating to a series
of Bearer Securities in the form of one or more global Debt Securities will be
described in the Prospectus Supplement relating to such series.
 
     Events of Default.  Any one of the following events constitutes an Event of
Default under each Debt Indenture with respect to Debt Securities of any series:
(a) failure to pay any interest on any Debt Security of that series when due,
continued for 30 days; (b) failure to pay principal of or any premium on any
Debt Security of that series when due; (c) failure to deposit any sinking fund
payment, when due, in respect of any Debt Security of that series; (d) failure
to perform any other covenant of the Company in such Debt Indenture (other than
a covenant included in such Debt Indenture solely for the benefit of series of
any Debt Securities other than that series), continued for 90 days after written
notice as provided in such Debt Indenture; (e) certain events in bankruptcy,
insolvency or reorganization involving the Company; and (f) any other Event of
Default provided with respect to Debt Securities of that series. (Section 501)
 
     If an Event of Default with respect to Debt Securities of any series at the
time Outstanding occurs and is continuing, either the Debt Trustee or the
Holders of at least 25% in aggregate principal amount of the Outstanding
Securities of that series by notice as provided in the applicable Debt Indenture
may declare the principal amount (or, if the Debt Securities of that series are
Original Issue Discount Securities, such portion of the principal amount as may
be specified in the terms of that series) of all the Debt Securities of that
series to be due and payable immediately. At any time after a declaration of
acceleration with respect to Debt Securities of any series has been made, but
before a judgment or decree for payment of money has been obtained by the Debt
Trustee, the Holders of a majority in aggregate principal amount of the
Outstanding Securities of that series may, under certain circumstances, rescind
and annul such acceleration. (Section 502)
 
     Each Debt Indenture provides that, subject to the duty of the Debt Trustee
during default to act with the required standard of care, the Debt Trustee is
under no obligation to exercise any of its rights or powers under such Debt
Indenture at the request or direction of any of the Holders, unless such Holders
shall have offered to the Debt Trustee reasonable indemnity. (Sections 601, 603)
Subject to such provisions for the indemnification of the Debt Trustee, the
Holders of a majority in aggregate principal amount of the Outstanding
Securities of any series have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Debt Trustee, or
exercising any trust or power conferred on the Debt Trustee, with respect to the
Debt Securities of that series; provided, however, that the Debt Trustee is not
obligated to take any action unduly prejudicial to Holders not joining in such
direction or involving the Debt Trustee in personal liability. (Section 512)
 
                                       20
<PAGE>   24
 
     The Company is required to furnish to the Debt Trustee annually a statement
as to the performance by the Company of its obligations under each Debt
Indenture and as to any default in such performance. (Section 1007)
 
     Defeasance.  If so specified with respect to any particular series of Debt
Securities issued under an Debt Indenture, the Company may discharge its
indebtedness and its obligations or certain of its obligations under such Debt
Indenture with respect to such series by depositing funds or obligations issued
or guaranteed by the United States of America with the Debt Trustee. (Sections
1301-1303)
 
     Defeasance and Discharge.  Each Debt Indenture provides that, if so
specified with respect to the Debt Securities of any series issued under such
Debt Indenture (other than convertible Subordinated Debt Securities), the
Company will be discharged from any and all obligations in respect of the Debt
Securities of such series (except for certain obligations relating to temporary
Debt Securities and exchange of Debt Securities, registration of transfer or
exchange of Debt Securities of such series, replacement of stolen, lost or
mutilated Debt Securities of such series, maintenance of paying agencies to hold
moneys for payment in trust and payment of additional amounts, if any, required
in consequence of United States withholding taxes imposed on payments to
non-United States persons) upon the deposit with the Trustee, in trust, of money
and/or U.S. Government Obligations which through the payment of interest and
principal in respect thereof in accordance with their terms will provide money
in an amount sufficient to pay the principal of (and premium, if any), and each
installment of interest on, the Debt Securities of such series on the Stated
Maturity of such payments in accordance with the terms of such Debt Indenture
and the Debt Securities of such series. (Sections 1302, 1304) Such a trust may
only be established if, among other things, the Company has delivered to the
Debt Trustee an Opinion of Counsel to the effect that (i) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling, or (ii) since the date of such Debt Indenture there has been a change in
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of such series
will not recognize income, gain or loss for United States federal income tax
purposes as a result of such deposit, defeasance and discharge, and will be
subject to United States federal income tax on the same amounts and in the same
manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred. (Section 1304) In the event of any
such defeasance and discharge of Debt Securities of such series, Holders of such
series would be entitled to look only to such trust fund for payment of
principal of and any premium and any interest on their Debt Securities until
Maturity.
 
     Covenant Defeasance.  Each Debt Indenture also provides that, if so
specified with respect to the Debt Securities of any series issued thereunder,
the Company may omit to comply with certain restrictive covenants, including (in
the case of the Senior Debt Indenture) the covenant described under "Limitation
on Liens" below, but excluding (in the case of the Subordinated Debt Indenture)
any applicable obligation of the Company respecting the conversion of Debt
Securities of such series into Common Stock, and any such omission shall not be
an Event of Default with respect to the Debt Securities of such series, upon the
deposit with the Debt Trustee, in trust, of money and/or U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of (and premium, if any), and each installment
of interest on, the Debt Securities of such series on the Stated Maturity of
such payments in accordance with the terms of such Debt Indenture and the Debt
Securities of such series. The obligations of the Company under such Debt
Indenture and the Debt Securities of such series other than with respect to such
covenants shall remain in full force and effect. (Section 1303) Such a trust may
be established only if, among other things, the Company has delivered to the
Debt Trustee an Opinion of Counsel to the effect that the Holders of such series
will not recognize income, gain or loss for United States federal income tax
purposes as a result of such deposit and defeasance of certain obligations and
will be subject to United States federal income tax on the same amounts and in
the same manner and at the same time as would have been the case if such deposit
and defeasance had not occurred. (Section 1304)
 
     Although the amount of money and U.S. Government Obligations on deposit
with the Debt Trustee would be intended to be sufficient to pay amounts due on
the Debt Securities of such series at the time of their Stated Maturity, in the
event the Company exercises its option to omit compliance with the covenants
 
                                       21
<PAGE>   25
 
defeased with respect to the Debt Securities of any series as described above,
and the Debt Securities of such series are declared due and payable because of
the occurrence of any Event of Default, such amount may not be sufficient to pay
amounts due on the Debt Securities of such series at the time of the
acceleration resulting from such Event of Default. The Company shall in any
event remain liable for such payments as provided in the applicable Debt
Indenture.
 
     Federal Income Tax Consequences Relating to Defeasance and Covenant
Defeasance.  Under current United States federal income tax law, defeasance and
discharge would likely be treated as a taxable exchange of Debt Securities to be
defeased for an interest in the defeasance trust. As a consequence, a holder
would recognize gain or loss equal to the difference between the holder's cost
or other tax basis for such Debt Securities and the value of the holder's
interest in the defeasance trust, and thereafter would be required to include in
income the holder's share of the income, gain or loss of the defeasance trust.
Under current United States federal income tax law, covenant defeasance would
ordinarily not be treated as a taxable exchange of such Debt Securities.
 
     Meetings, Modification and Waiver.  Modifications and amendments of either
Debt Indenture may be made by the Company and the Debt Trustee with the consent
of the Holders of a majority in aggregate principal amount of the Outstanding
Securities of each series affected by such modification or amendment; provided,
however, that no such modification or amendment may, without consent of the
Holder of each Outstanding Security affected thereby, (a) change the Stated
Maturity of the principal of, or any installment of principal of or interest on,
any Debt Security, (b) change the Redemption Date with respect to any Debt
Security, (c) reduce the principal amount of, or premium or interest on, any
Debt Security, (d) change any obligation of the Company to pay additional
amounts, (e) reduce the amount of principal of an Original Issue Discount
Security payable upon acceleration of the Maturity thereof, (f) change the coin
or currency in which any Debt Security or any premium or interest thereon is
payable, (g) change the redemption right of any Holder, (h) impair the right to
institute suit for the enforcement of any payment on or with respect to any Debt
Security or any conversion right with respect thereto, (i) reduce the percentage
in principal amount of Outstanding Securities of any series, the consent of
whose Holders is required for modification or amendment of such Debt Indenture
or for waiver of compliance with certain provisions of such Debt Indenture or
for waiver of certain defaults, (j) reduce the requirements contained in such
Debt Indenture for quorum or voting, (k) change any obligation of the Company to
maintain an office or agency in the places and for the purposes required by such
Debt Indenture, (l) adversely affect the right to convert Subordinated Debt
Securities, if applicable, or (m) modify any of the above provisions. (Section
902)
 
     The Subordinated Debt Indenture may not be amended to alter the
subordination of any outstanding Subordinated Debt Securities without the
consent of each holder of Senior Indebtedness (as defined below under
"-- Provisions Applicable Solely to Subordinated Debt Securities") then
outstanding that would be adversely affected thereby. (Section 907 of the
Subordinated Debt Indenture)
 
     The Holders of a majority in aggregate principal amount of the Outstanding
Securities of each series may, on behalf of all Holders of that series, waive,
insofar as that series is concerned, compliance by the Company with certain
restrictive provisions of the Debt Indenture under which such series has been
issued. (Section 1008) The Holders of a majority in aggregate principal amount
of the Outstanding Securities of each series may, on behalf of all Holders of
that series, waive any past default under the applicable Debt Indenture with
respect to any Debt Securities of that series, except a default (a) in the
payment of principal of, or premium, if any, or any interest on any Debt
Security of such series or (b) in respect of a covenant or provision of such
Debt Indenture which cannot be modified or amended without the consent of the
Holder of each Outstanding Security of such series affected. (Section 513)
 
     Each Debt Indenture provides that in determining whether the Holders of the
requisite principal amount of the Outstanding Securities have given any request,
demand, authorization, direction, notice, consent or waiver thereunder or are
present at a meeting of the Holders for quorum purposes, (i) the principal
amount of an Original Issue Discount Security that is deemed to be Outstanding
will be the amount of the principal that would be due and payable as of the date
of such determination upon acceleration of the Maturity thereof, and (ii) the
principal amount of a Debt Security denominated in a foreign currency or
currency units will be the
 
                                       22
<PAGE>   26
 
U.S. dollar equivalent, determined on the date of original issuance of such Debt
Security, of the principal amount of such Debt Security or, in the case of an
Original Issue Discount Security, the U.S. dollar equivalent, determined on the
date of original issuance of such Security, of the amount determined as provided
in (i) above. (Section 101)
 
     Each Debt Indenture contains provisions for convening meetings of the
Holders of a series if Debt Securities of that series are issuable as Bearer
Securities. (Section 1401) A meeting may be called at any time by the Trustee,
and also, upon request, by the Company or the Holders of at least 10% in
aggregate principal amount of the Outstanding Securities of such series, in any
such case upon notice given in accordance with "-- Notices" below. (Section
1402) Except for any consent which must be given by the Holder of each
Outstanding Security affected thereby, as described above, any resolution
presented at a meeting (or adjourned meeting at which a quorum is present) may
be adopted by the affirmative vote of the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series; provided,
however, that any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action which may be made, given or
taken by the Holders of a specified percentage, which is less than a majority,
in aggregate principal amount of the Outstanding Securities of a series may be
adopted at a meeting (or adjourned meeting duly reconvened at which a quorum is
present) by the affirmative vote of the Holders of such specified percentage in
aggregate principal amount of the Outstanding Securities of that series. Any
resolution passed or decision taken at any meeting of Holders of any series duly
held in accordance with the applicable Debt Indenture will be binding on all
Holders of that series and related coupons. The quorum at any meeting, and at
any reconvened meeting, will be Persons holding or representing a majority in
aggregate principal amount of the Outstanding Securities of a series. (Section
1404)
 
     Consolidation, Merger and Sale of Assets.  The Company, without the consent
of the Holders of any of the outstanding Debt Securities under either Debt
Indenture, may consolidate with or merge into, or convey, transfer or lease its
assets substantially as an entirety to, any Person which is a corporation,
partnership or trust organized and validly existing under the laws of any
domestic jurisdiction, provided that any successor Person assumes the Company's
obligations on the Securities and under such Debt Indenture, that after giving
effect to the transaction no Event of Default, and no event which, after notice
or lapse of time, would become an Event of Default, shall have occurred and be
continuing, and that certain other conditions are met. (Section 801)
 
     Notices.  Except as otherwise provided in the Debt Indentures, notices to
Holders of Bearer Securities will be given by publication at least twice in a
daily newspaper in The City of New York and in such other city or cities as may
be specified in such Bearer Securities. Notices to Holders of Registered
Securities will be given by mail to the addresses of such Holders as they appear
in the Security Register. (Section 106)
 
     Title.  Title to any Bearer Securities (including Bearer Securities in
permanent global form) and any coupons appertaining thereto will pass by
delivery. The Company, the Debt Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any coupon
and the registered owner of any Registered Security as the owner thereof
(whether or not such Debt Security or coupon shall be overdue and
notwithstanding any notice to the contrary) for the purpose of making payment
and for all other purposes. (Section 308)
 
     Replacement of Securities and Coupons.  Any mutilated Debt Security or a
Debt Security with a mutilated coupon appertaining thereto will be replaced by
the Company at the expense of the Holder upon surrender of such Debt Security to
the Debt Trustee. Debt Securities or coupons that became destroyed, stolen or
lost will be replaced by the Company at the expense of the Holder upon delivery
to the Debt Trustee of the Debt Security and coupons or evidence of destruction,
loss or theft thereof satisfactory to the Company and the Debt Trustee; in the
case of any coupon which becomes destroyed, stolen or lost, such coupon will be
replaced by issuance of a new Debt Security in exchange for the Debt Security to
which such coupon appertains. In the case of a destroyed, lost or stolen Debt
Security or coupon, an indemnity satisfactory to the Debt Trustee and the
Company may be required at the expense of the Holder of such Debt Security or
coupon before a replacement Debt Security will be issued. (Section 306)
 
                                       23

     Governing Law.  The Debt Indentures, the Debt Securities and coupons will
be governed by, and construed in accordance with, the laws of the State of New
York. (Section 113)
 
     Regarding the Trustee.  First Trust National Association, the Debt Trustee
under each Debt Indenture, is also trustee under another indenture under which
several issues of the Company's debt securities are outstanding.
 
     Each Debt Indenture contains certain limitations on the right of the Debt
Trustee, should it become a creditor of the Company, to obtain payment of claims
in certain cases, or to realize for its own account on certain property received
in respect of any such claim as security or otherwise. (Section 613) The Debt
Trustee is permitted to engage in certain other transactions; however, if it
acquires any conflicting interest (as described in the Debt Indentures), it must
eliminate such conflict or resign. (Section 608)
 
     Pursuant to the Trust Indenture Act, should a default occur with respect to
either the Senior Debt Securities or the Subordinated Debt Securities, First
Trust National Association would be required to resign as Debt Trustee under one
of the Debt Indentures within 90 days of such default unless such default were
cured, duly waived or otherwise eliminated.
 
PROVISIONS APPLICABLE SOLELY TO SENIOR DEBT SECURITIES
 
     General.  Senior Debt Securities will be issued under the Senior Debt
Indenture, and each series will rank pari passu as to the right of payment of
principal and any premium and interest with each other series issued thereunder
and will rank senior to all series of Subordinated Debt Securities that may be
issued.
 
     Certain Definitions.  For purposes of the following discussion, the
following definitions are applicable (Section 101 of the Senior Debt Indenture):
 
     "Net Tangible Assets" means the total amount of assets appearing on a
consolidated balance sheet of the Company and its Subsidiaries less, without
duplication: (a) all current liabilities (excluding any thereof which are
extendible or renewable by their terms or replaceable or refundable pursuant to
enforceable commitments at the option of the obligor thereon without requiring
the consent of the obligee to a time more than 12 months after the time as of
which the amount thereof is being computed and excluding current maturities of
long-term debt and preferred stock); (b) all reserves for depreciation and other
asset valuation reserves but excluding reserves for deferred federal income
taxes arising from accelerated depreciation or otherwise; (c) all goodwill,
trademarks, trade names, patents and unamortized debt discount and expense and
other like intangible assets carried as an asset and (d) all appropriate
adjustments on account of minority interests of other Persons holding common
stock in any Subsidiary.
 
     "Person" means any individual, corporation, partnership, joint venture,
trust, unincorporated organization or government or any agency or political
subdivision thereof.
 
     "Principal Property" means any natural gas pipeline, natural gas
distribution system, natural gas gathering system or natural gas storage
facility located in the United States, except any such property that in the
opinion of the Board of Directors is not of material importance to the business
conducted by the Company and its consolidated Subsidiaries taken as a whole.
 
     "Principal Subsidiary" means any Subsidiary which owns a Principal
Property.
 
     "Subsidiary" means a corporation more than 50% of the outstanding stock of
which is owned, directly or indirectly, by the Company or by one or more
Subsidiaries, or by the Company and one or more other Subsidiaries. For the
purposes of this definition, "voting stock" means stock which ordinarily has
voting power for the election of directors, whether at all times or only so long
as no senior class of stock has such voting power by reason of any contingency.
 
     Limitation on Liens.  The Company covenants in the Senior Debt Indenture
that it will not, nor will it permit any Subsidiary to, issue, assume or
guarantee any debt for money borrowed ("Debt") if such Debt is secured by a
mortgage, pledge, security interest or lien (a "mortgage" or "mortgages") upon
any Principal Property of the Company or any Principal Subsidiary or upon any
shares of stock or indebtedness of any
 
                                       24
<PAGE>   28
 
Principal Subsidiary (whether such Principal Property, shares or indebtedness
was owned on the date of the Senior Debt Indenture or thereafter acquired)
without in any such case effectively providing that the Senior Debt Securities
shall be secured equally and ratably with (or prior to) such Debt, except that
the foregoing restrictions shall not apply to: (a) mortgages on any property
acquired, constructed or improved by the Company or any Principal Subsidiary
after the date of the Senior Debt Indenture which are created within 180 days
after such acquisition (or in the case of property constructed or improved,
after the completion and commencement of commercial operation of such property,
whichever is later) to secure or provide for the payment of the purchase price
or cost thereof, provided that in the case of such construction or improvement
the mortgages shall not apply to any property theretofore owned by the Company
or any Subsidiary other than theretofore unimproved real property; (b) existing
mortgages on property acquired (including mortgages on any property acquired
from a Person which is consolidated with or merged with or into the Company or a
Subsidiary) or mortgages outstanding at the time any corporation becomes a
Subsidiary; (c) mortgages in favor of domestic or foreign governmental bodies to
secure advances or other payments pursuant to any contract or statute or to
secure indebtedness incurred to finance the purchase price or cost of
constructing or improving the property subject to such mortgages, including
mortgages to secure Debt of the pollution control or industrial revenue bond
type; (d) mortgages in favor of the Company or any Principal Subsidiary; or (e)
any extension, renewal or replacement (or successive extensions, renewals or
replacements), in whole or in part, of any mortgage referred to in any of the
foregoing clauses (a)-(d). (Section 1006 of the Senior Debt Indenture)
 
     Notwithstanding the foregoing, the Company and any Subsidiary may, without
securing the Senior Debt Securities, issue, assume or guarantee secured Debt
(which would otherwise be subject to the foregoing restrictions) in an aggregate
amount which, together with all other such Debt, does not exceed 10% of the Net
Tangible Assets, as shown on a consolidated balance sheet as of a date not more
than 90 days prior to the proposed transaction prepared by the Company in
accordance with generally accepted accounting principles. (Section 1006 of the
Senior Debt Indenture)
 
PROVISIONS APPLICABLE SOLELY TO SUBORDINATED DEBT SECURITIES
 
     Subordination.  The Subordinated Debt Securities will be subordinate and
junior in right of payment, to the extent set forth in the Subordinated Debt
Indenture, to all Senior Indebtedness (as defined below) of the Company. If the
Company should default in the payment of any principal of or premium or interest
on any Senior Indebtedness when the same becomes due and payable, whether at
Stated Maturity or a date fixed for prepayment or by declaration of acceleration
or otherwise, then, upon written notice of such default to the Company by the
holders of such Senior Indebtedness or any trustee therefor and subject to
certain rights of the Company to dispute such default and subject to proper
notification of the Trustee, unless and until such default has been cured or
waived or ceases to exist, no direct or indirect payment (in cash, property,
securities, by set-off or otherwise) will be made or agreed to be made for
principal of, premium, if any, or interest, if any, on the Subordinated Debt
Securities, or in respect of any redemption, retirement, purchase or other
acquisition of the Subordinated Debt Securities other than those made in capital
stock of the Company (or cash in lieu of fractional shares thereof) pursuant to
any conversion right of the Subordinated Debt Securities or otherwise made in
capital stock of the Company. (Sections 1601, 1604 and 1605 of the Subordinated
Debt Indenture)
 
     "Senior Indebtedness" is defined in Section 101 of the Subordinated Debt
Indenture as Indebtedness (as defined below) of the Company outstanding at any
time except (a) any Indebtedness as to which, by the terms of the instrument
creating or evidencing the same, it is provided that such Indebtedness is not
senior in right of payment to the Subordinated Debt Securities, (b) the
Subordinated Debt Securities, (c) any Indebtedness of the Company to a
wholly-owned Subsidiary of the Company, (d) interest accruing after the filing
of a petition initiating certain bankruptcy or insolvency proceedings unless
such interest is an allowed claim enforceable against the Company in a
proceeding under federal or state bankruptcy laws and (e) trade accounts
payable. "Indebtedness" is defined in Section 101 of the Subordinated Debt
Indenture as, with respect to any Person, (a) (i) the principal of and premium
and interest, if any, on indebtedness for money borrowed of such Person
evidenced by bonds, notes, debentures or similar obligations, including any
guaranty
 
                                       25
<PAGE>   29
 
by such Person of any indebtedness for money borrowed of any other Person,
whether any such indebtedness or guaranty is outstanding on the date of the
Subordinated Debt Indenture or is thereafter created, assumed or incurred, (ii)
the principal of and premium and interest, if any, on indebtedness for money
borrowed, incurred, assumed or guaranteed by such Person in connection with the
acquisition by it or any of its subsidiaries of any other business, properties
or other assets and (iii) lease obligations which such Person capitalizes in
accordance with Statement of Financial Accounting Standards No. 13 promulgated
by the Financial Accounting Standards Board or such other generally accepted
accounting principles as may be from time to time in effect, (b) any other
indebtedness of such Person, including any indebtedness representing the balance
deferred and unpaid of the purchase price of any property or interest therein,
including any such balance that constitutes a trade account payable, and any
guaranty, endorsement or other contingent obligation of such Person in respect
of any indebtedness of another, which is outstanding on the date of the
Subordinated Debt Indenture or is thereafter created, assumed or incurred by
such Person and (c) any amendments, modifications, refundings, renewals or
extensions of any indebtedness or obligation described as Indebtedness in clause
(a) or (b) above.
 
     If (i) without the consent of the Company a court shall enter (A) an order
for relief with respect to the Company under the United States federal
bankruptcy laws, (B) a judgment, order or decree adjudging the Company a
bankrupt or insolvent, or (C) an order for relief for reorganization,
arrangement, adjustment or composition of or in respect of the Company under the
United States federal bankruptcy laws or state insolvency laws or (ii) the
Company shall institute proceedings for the entry of an order for relief with
respect to the Company under the United States federal bankruptcy laws or for an
adjudication of insolvency, or shall consent to the institution of bankruptcy or
insolvency proceedings against it, or shall file a petition seeking, or seek or
consent to reorganization, arrangement, composition or similar relief under any
applicable law, or shall consent to the filing of such petition or to the
appointment of a receiver, custodian, liquidator, assignee, trustee,
sequestrator or similar official in respect of the Company or of substantially
all of its property, or the Company shall make a general assignment for the
benefit of creditors, then all Senior Indebtedness (including any interest
thereon accruing after the commencement of any such proceedings) will first be
paid in full before any payment or distribution, whether in cash, securities or
other property, is made on account of the principal of, premium, if any, or
interest, if any, on the Subordinated Debt Securities. In such event, any
payment or distribution on account of the principal of, premium, if any, or
interest, if any, on the Subordinated Debt Securities, whether in cash,
securities or other property (other than securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment the payment
of which is subordinate, at least to the extent provided in the subordination
provisions with respect to the Subordinated Debt Securities, to the payment of
all Senior Indebtedness then outstanding and to any securities issued in respect
thereof under any such plan of reorganization or readjustment), which would
otherwise (but for the subordination provisions) be payable or deliverable in
respect of the Subordinated Debt Securities will be paid or delivered directly
to the holders of Senior Indebtedness in accordance with the priorities then
existing among such holders until all Senior Indebtedness (including any
interest thereon accruing after the commencement of any such proceedings) has
been paid in full. If any payment or distribution on account of the principal
of, premium, if any, or interest, if any, on the Subordinated Debt Securities of
any character, whether in cash, securities or other property (other than
securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in the subordination provisions with respect to the
Subordinated Debt Securities, to the payment of all Senior Indebtedness then
outstanding and to any securities issued in respect thereof under any such plan
of reorganization or readjustment), shall be received by the Debt Trustee or any
Holder of any Subordinated Debt Securities in contravention of any of the terms
of the Subordinated Debt Indenture, such payment or distribution will be
received in trust for the benefit of, and will be paid over or delivered and
transferred to, the holders of the Senior Indebtedness then outstanding in
accordance with the priorities then existing among such holders for application
to the payment of all Senior Indebtedness remaining unpaid, to the extent
necessary to pay all such Senior Indebtedness in full. In the event of any such
proceeding, after payment in full of all sums owing with respect to Senior
Indebtedness, the Holders of Subordinated Debt Securities, together with the
holders of any other obligations of the Company ranking on a parity with the
Subordinated Debt Securities, will be entitled to be repaid from the remaining
assets of the Company the amounts at that time
 
                                       26
<PAGE>   30
 
due and owing on account of unpaid principal of or any premium or interest on
the Subordinated Debt Securities and such other obligations before any payment
or other distribution, whether in cash, property or otherwise, shall be made on
account of any capital stock or obligations of the Company ranking junior to the
Subordinated Debt Securities and such other obligations. (Section 1601 of the
Subordinated Debt Indenture)
 
     The Prospectus Supplement respecting any series of Subordinated Debt
Securities will set forth any subordination provisions applicable to such series
in addition to or different from those described above.
 
     By reason of such subordination, in the event of the insolvency of the
Company, Holders of Senior Indebtedness and holders of other obligations of the
Company that are not subordinated to Senior Indebtedness may receive more,
ratably, than Holders of the Subordinated Debt Securities. Such subordination
will not prevent the occurrence of an Event of Default or limit the right of
acceleration in respect of the Subordinated Debt Securities.
 
     Conversion.  The Subordinated Debt Indenture may provide for a right of
conversion of Subordinated Debt Securities into Common Stock (or cash in lieu
thereof). (Sections 301 and 1501 of the Subordinated Debt Indenture) The
following provisions will apply to Debt Securities that are convertible
Subordinated Debt Securities unless otherwise provided in the Prospectus
Supplement for such Debt Securities.
 
     The Holder of any convertible Subordinated Debt Securities will have the
right exercisable at any time set forth in the Prospectus Supplement, unless
previously redeemed or otherwise purchased by the Company, to convert such
Subordinated Debt Securities into shares of Common Stock at the conversion price
or conversion rate set forth in the Prospectus Supplement, subject to
adjustment. (Section 1502 of the Subordinated Debt Indenture) The holder of
convertible Subordinated Debt Securities may convert any portion thereof which
is $1,000 in principal amount or any integral multiple thereof. (Section 1502 of
the Subordinated Debt Indenture)
 
     In certain events, the conversion price or conversion rate will be subject
to adjustment as set forth in the Subordinated Debt Indenture. Such events
include the issuance of shares of Common Stock of the Company as a dividend or
distribution on the Common Stock; subdivisions, combinations and
reclassifications of the Common Stock; the issuance to all holders of Common
Stock of rights or warrants entitling the holders thereof (for a period not
exceeding 45 days) to subscribe for or purchase shares of Common Stock at a
price per share less than the then current market price per share of Common
Stock (as determined pursuant to the Subordinated Debt Indenture); and the
distribution to substantially all holders of Common Stock of evidences of
indebtedness, equity securities (including equity interests in the Company's
Subsidiaries) other than Common Stock, or other assets (excluding cash dividends
paid from surplus) or subscription rights or warrants (other than those referred
to above). No adjustment of the conversion price or conversion rate will be
required unless an adjustment would require a cumulative increase or decrease of
at least 1% in such price or rate. (Section 1504 of the Subordinated Debt
Indenture) Certain adjustments in the conversion price or conversion rate in
accordance with the foregoing provisions may result in constructive
distributions to either holders of the Subordinated Debt Securities or holders
of Common Stock which would be taxable pursuant to Treasury Regulations issued
under section 305 of the Internal Revenue Code of 1986, as amended. The amount
of any such taxable constructive distribution would be the fair market value of
the Common Stock which is treated as having been constructively received, such
value being determined as of the time the adjustment resulting in the
constructive distribution is made.
 
     Fractional shares of Common Stock will not be issued upon conversion, but,
in lieu thereof, the Company will pay a cash adjustment based on the then
current market price for the Common Stock. (Section 1503 of the Subordinated
Debt Indenture) Upon conversion, no adjustments will be made for accrued
interest or dividends, and therefore convertible Subordinated Debt Securities
surrendered for conversion between the record date for an interest payment and
the Interest Payment Date (except convertible Subordinated Debt Securities
called for redemption on a redemption date during such period) must be
accompanied by payment of an amount equal to the interest thereon which the
registered holder is to receive. (Sections 1504 and 1502 of the Subordinated
Debt Indenture)

     In the case of any consolidation or merger of the Company (with certain
exceptions) or any conveyance, transfer or lease of the properties and assets of
the Company substantially as an entirety to any Person, each Holder of
convertible Subordinated Debt Securities, after the consolidation, merger,
conveyance, transfer or lease, will have the right to convert such convertible
Subordinated Debt Securities only into the kind and amount of securities, cash
and other property which the Holder would have been entitled to receive upon or
in connection with such consolidation, merger, conveyance, transfer or lease, if
the Holder had held the Common Stock issuable upon conversion of such
convertible Subordinated Debt Securities immediately prior to such
consolidation, merger, conveyance, transfer or lease. (Section 1505 of the
Subordinated Debt Indenture)

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     K N is currently authorized by its Restated Articles of Incorporation, as
amended (the "K N Charter") to issue 50,000,000 shares of Common Stock, of which
32,024,557 were outstanding on December 31, 1997; 200,000 shares of Class A
Preferred Stock, no par value ("Class A Preferred Stock"), of which 70,000
shares were outstanding as Class A $5.00 Cumulative Preferred Stock on such
date; and 2,000,000 shares of Class B Preferred Stock, no par value ("Class B
Preferred Stock"), none of which were outstanding on such date.
 
     The Board of Directors of K N is authorized by the K N Charter to provide,
without further stockholder action, for the issuance of one or more series of
Class A Preferred Stock and Class B Preferred Stock. The Board of Directors has
the power to fix various terms with respect to each such series, including
voting power, designations, preferences, dividend rates, conversion and exchange
provisions, redemption provisions and, in the case of the Class B Preferred
Stock, the amounts which holders are entitled to receive upon any liquidation,
dissolution or winding up of K N. Class A Preferred Stock and Class B Preferred
Stock will rank prior to the Common Stock with respect to both dividends and
distribution of assets on liquidation, dissolution or winding up of K N.
 
     In the event of any liquidation, dissolution or winding up of K N, whether
voluntary or involuntary, the holders of shares of Class A Preferred Stock of
each series shall be entitled to receive in full out of the assets of K N the
sum of $100 per share of Class A Preferred Stock, plus any arrearages in
dividends thereon to the date fixed for the payment in liquidation, before any
distribution shall be made to the holders of shares of any stock junior to the
Class A Preferred Stock. K N may, at the option of the Board of Directors,
redeem the whole or any part of the Class A Preferred Stock, or of any series
thereof at any time or from time to time within the period during which such
stock is, according to the K N Charter, or the resolutions of the Board of
Directors providing for the issue thereof, redeemable, by paying the redemption
price thereof, including any arrearages in dividends thereon to the date fixed
for redemption. The Class A $5.00 Cumulative Preferred Stock is redeemable, in
whole or in part, at the option of K N at any time, or from time to time, at the
price of $105 per share plus accrued and unpaid dividends. This series has no
sinking fund requirements. Holders of shares of Class A $5.00 Cumulative
Preferred Stock are entitled to receive, when and as declared by the Board of
Directors of K N, cumulative preferential cash dividends at the annual rate of
$5.00 per share prior to the payment of any dividends or other distributions on
(or purchase or redemption of) the Class B Preferred Stock or the Common Stock.
 
     In the event of any liquidation, dissolution or winding up of K N, whether
voluntary or involuntary, the holders of shares of Class B Preferred Stock of
each series shall be entitled to receive, subject to the prior rights of the
holders of shares of Class A Preferred Stock, the full preferential amount fixed
by the K N Charter, or by the resolutions of the Board of Directors providing
for the issue thereof, including any arrearages in dividends thereon to the date
fixed for the payment in liquidation, before any distribution shall be made to
the holders of shares of any stock junior to the Class B Preferred Stock.
Dividends may not be declared or paid or set apart for payment on any series of
Class B Preferred Stock, unless there shall be no arrearages in dividends on any
series of Class A Preferred Stock entitled to cumulative dividends for any past
dividend period and dividends in full for the current dividend period have been
paid or declared or set aside for payment on all Class A Preferred Stock.
 
     In addition, the holders of the Class A Preferred Stock then outstanding
have the right to vote separately as a class with respect to (i) certain
amendments to the K N Charter or the By-Laws of K N which adversely affect the
voting powers, rights or preferences of the holders of shares of Class A
Preferred Stock, (ii) the creation of any class of stock or any security
convertible into or exchangeable for or evidencing the right to purchase any
stock ranking prior to or on a parity with, either as to dividends or upon
liquidation, the Class A Preferred Stock, or (iii) certain mergers or
consolidations of K N with or into any other corporation. For such actions to be
taken by K N, including increasing the authorized amount of any class of stock
ranking prior to the Class A Preferred Stock, the affirmative vote of the
holders of at least 50% of the shares of the Class A Preferred Stock then
outstanding would be required. The affirmative vote of at least 50% of the
shares of any
 
                                       29
<PAGE>   33
 
series of Class A Preferred Stock then outstanding is required for K N to amend
the K N Charter or resolutions of the Board of Directors of K N providing for
the issue of such series of Class A Preferred Stock so as to affect adversely
the powers, preferences or rights of holders of Class A Preferred Stock of such
series. The holders of Class B Preferred Stock then outstanding also have the
right to a separate vote regarding (a) the events described in the first
sentence of this paragraph with regard to such Class B Preferred Stock,
requiring the affirmative vote of at least 50% of the shares of Class B
Preferred Stock then outstanding, and (b) amendments to the K N Charter, or to
resolutions of K N's Board of Directors providing for the issue of any series of
Class B Preferred Stock so as to affect adversely the powers, preferences or
rights of the holders of such series, requiring the affirmative vote of at least
50% of the shares of such series then outstanding.
 
     If dividends are in arrears on the shares of any series of Class A
Preferred Stock to which the following provisions are made applicable pursuant
to the K N Charter or resolutions of K N's Board of Directors providing for the
issue of any such series (i) in an aggregate amount equal to three but less than
six full quarterly dividends, then the holders of the shares of all such series
of Class A Preferred Stock have the exclusive right, voting separately as a
class and without regard to series, to elect directors constituting one-third of
K N's Board of Directors or (ii) in an aggregate amount equal to six full
quarterly dividends, then such holders have the exclusive right, voting
separately as a class and without regard to series, to elect directors
constituting one-half of K N's Board of Directors plus one additional director,
in each case until all arrearages in dividends and dividends in full for the
current quarterly period have been paid on or declared and set aside for payment
on the shares of such series. These provisions are applicable to the Class A
$5.00 Cumulative Preferred Stock. The holders of any outstanding Class B
Preferred Stock would have the right to elect directors of K N similar to the
Class A $5.00 Cumulative Preferred Stock in the event of nondeclaration of
dividends, for the periods described above, on the Class B Preferred Stock if
the holders of the Class A $5.00 Cumulative Preferred Stock are not then
entitled to elect directors as described above.
 
     All outstanding shares of Common Stock are, and any shares of Common Stock
newly issued under any Prospectus Supplement will be, validly issued, fully paid
and nonassessable. Holders of K N Common Stock and Class A $5.00 Cumulative
Preferred Stock are entitled to one vote for each share on all matters voted on
by stockholders. Holders of Common Stock, Class A Preferred Stock and Class B
Preferred Stock have no preemptive rights to subscribe for or purchase any
additional securities issued by K N. Subject to the preferential rights of the
holders of the Class A Preferred Stock and Class B Preferred Stock, the holders
of Common Stock are entitled to receive any dividends which may be declared by
the Board of Directors out of funds legally available therefor and to share pro
rata in the net assets of K N upon liquidation, dissolution or winding up.
Shares of Common Stock have no cumulative voting rights or redemption, sinking
fund or conversion privileges.
 
ANTI-TAKEOVER MATTERS
 
     Charter and Bylaws.  Certain provisions of the K N Charter and the By-Laws
of K N could have the effect of preventing a change in control of K N in certain
situations. These provisions generally provide for (a) the classification of the
Board of Directors of K N into three classes of as nearly an equal number as
possible, having staggered terms of three years each; (b) the removal of
directors only for cause or by unanimous vote of the remaining members of the
Board of Directors; (c) the filling of any vacancy on the Board of Directors by
the remaining directors then in office; (d) the limitation of the number of
directors to a minimum of nine and a maximum of 15, with the exact number to be
determined by the Board of Directors; (e) increasing the stockholder vote
required to amend, repeal or adopt any provision inconsistent with the foregoing
provisions under (a), (b) and (d) above to two-thirds of the outstanding voting
securities of K N; (f) the requirement that certain business combinations or
transactions involving K N and any beneficial owner of more than 5% of the
outstanding voting securities of K N be approved by holders of at least
twothirds of the outstanding voting securities of K N, including those held by
such beneficial owner, unless the business combination or transaction is (I)
approved by the Board of Directors before such beneficial owner became a holder
of more than 5% of K N's outstanding voting securities or (II) approved by
sufficient members of the Board of Directors to constitute a majority of the
members of the full Board of Directors in office prior to the time such
beneficial owner became a holder of more than 5% of K N's voting securities, or
(III) with an entity
 
                                       30
<PAGE>   34
 
of which a majority of the outstanding shares of voting securities is owned by K
N and its subsidiaries; (g) increasing the stockholder vote required to amend,
repeal or adopt any provision inconsistent with the foregoing provision under
(f) above to two-thirds or more of the then outstanding shares of voting
securities of K N; (h) the requirement that certain business combinations or
transactions involving K N and any beneficial owner of 10% or more of the
outstanding voting securities of K N be approved by holders of at least 80% of
the outstanding voting securities of K N, including those held by such
beneficial owner, unless (I) the business combination or transaction is approved
by three-fourths of the Board of Directors then in office who are not associated
with or related to anyone who beneficially owns, and do not themselves own, 10%
or more of K N's voting securities or (II) certain conditions relating generally
to the fairness of the price to be received by stockholders of K N in such
business combination or transaction are satisfied; (i) increasing the
stockholder vote required to amend, repeal or adopt any provision inconsistent
with the foregoing provision under (h) above to 80% or more of the outstanding
voting securities of K N unless approved by an affirmative vote of three-fourths
of the Board of Directors then in office who are not associated with or related
to anyone who beneficially owns, and do not themselves own, 10% or more of K N's
voting securities; (j) certain procedural requirements for stockholder
nominations to the Board of Directors; and (k) the requirement that special
meetings of stockholders may only be called by stockholders owning 51% or more
of the outstanding voting securities of K N, by a majority of the Board of
Directors, the Chairman of the Board of Directors or the President of K N.
 
     Shareholder Rights Plan.  On August 17, 1995, the Board of Directors of K N
declared a dividend of one preferred share purchase right (a "Right") with
respect to each outstanding share of Common Stock held of record on September
15, 1995 or issued thereafter and prior to the date the Rights become
exercisable. Until the Rights become exercisable, they will be evidenced by
certificates for shares of Common Stock and will automatically trade with the
Common Stock. If and when the Rights become exercisable, Rights certificates
will be distributed and the Rights will become separately tradable. The full
terms of the Rights are set forth in the Rights Agreement, dated as of August
21, 1995 (the "Rights Agreement"), between the Company and The Bank of New York,
as Rights Agent. A copy of the Rights Agreement is filed as an exhibit to the
Registration Statement.
 
     Each Right entitles the holder thereof to purchase from the Company one
one-thousandth of a share of Class B Junior Participating Series Preferred
Stock, without par value (the "Preferred Shares"), for a price of $80 per one
onethousandth of a Preferred Share (the "Purchase Price"), subject to
adjustment. The Rights become exercisable upon the earlier of (i) ten business
days following a public announcement that a person or group of affiliated or
associated persons has acquired beneficial ownership of 20% or more of the
outstanding voting shares of the Company or (ii) ten business days following the
commencement or announcement of an intention to commence a tender or exchange
offer the consummation of which would result in the beneficial ownership by a
person or group of 20% or more of the outstanding voting shares of the Company.
The Rights will expire on the later of September 15, 2005 or the third
anniversary of the date on which the Rights became exercisable (the "Final
Expiration Date"), unless the Final Expiration Date is extended or the Rights
are earlier redeemed or exchanged by the Company as described below.
 
     If a person or group were to acquire 20% or more of the voting shares of
the Company, each Right then outstanding (other than Rights beneficially owned
by the acquiring person, which would become null and void) would become a right
to buy that number of shares of Common Stock (or, under certain circumstances,
the equivalent number of one onethousandths of a Preferred Share) that at the
time of such acquisition would have a market value of two times the Purchase
Price of the Right. If the Company were acquired in a merger or other business
combination transaction or more than 50% of its consolidated assets or earning
power were sold, proper provision will be made so that holder of a Right will
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase Price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction would have a market
value of two times the Purchase Price of the Right.
 
     At any time after the acquisition by a person or group of beneficial
ownership of 20% or more of the outstanding voting shares of the Company and
before the acquisition by a person or group of 50% or more of the outstanding
voting shares of the Company, the Board of Directors may, at its option, issue
shares of
 
                                       31
<PAGE>   35
 
Common Stock (or Preferred Shares) in mandatory redemption of, and in exchange
for, all or part of the then outstanding and exercisable Rights (other than
Rights owned by such person or group, which would become null and void) at an
exchange ratio of one share of Common Stock (or one one-thousandth of a
Preferred Share) for each Right, subject to adjustment. In addition, the Company
is entitled to redeem all of the outstanding Rights at a price of $0.01 per
Right at any time prior to the first public announcement that a person or group
has become the beneficial owner of 20% or more of the outstanding voting shares
of the Company.
 
     Until a Right is exercised, the holder thereof, as such, has no rights as a
stockholder of the Company, including, without limitation, the right to vote or
to receive dividends.
 
KANSAS BUSINESS COMBINATION ACT
 
     K N is subject to Sections 17-12,100 et seq. of the Kansas Statutes
Annotated (the "K.S.A."), which imposes a three-year moratorium on business
combinations between a Kansas corporation and an "interested stockholder" (in
general, a stockholder owning 15% or more of a corporation's outstanding voting
stock) or an affiliate or associate thereof unless (a) prior to an interested
stockholder becoming such, the board of directors of the corporation has
approved either the business combination or the transaction by which the
interested stockholder became such; (b) upon consummation of the transaction
resulting in an interested stockholder becoming such, the interested stockholder
owns 85% of the voting stock that was outstanding at the time the transaction
commenced (excluding, from the calculation of outstanding shares, shares
beneficially owned by management, directors and certain employees stock plans);
or (c) on or after the date an interested stockholder becomes such, the business
combination is approved by (i) the Board of Directors and (ii) the affirmative
vote of the holders of at least 66 2/3% of the outstanding shares (other than
those shares beneficially owned by the interested stockholder) at a meeting of
stockholders.
 
KANSAS CONTROL SHARE ACQUISITIONS ACT
 
     K N is also subject to Sections 17-1286 et seq. of the K.S.A. (the "Kansas
Control Share Acquisitions Act"), which applies to public corporations
incorporated in Kansas that have certain other connections with the state. The
Kansas Control Share Acquisitions Act relates principally to the acquisition of
"control shares" in such a corporation. Under the Kansas Control Share
Acquisitions Act, a control share acquisition is one that, except for the
operation of the Act, would raise the acquiring person's voting power in the
election of directors of the subject corporation to or above any of three
thresholds: one-fifth or more but less than one-third of all voting power;
one-third or more but less than a majority of all voting power; and at least a
majority of all voting power. Whenever a control share acquisition occurs, the
acquiring person has no voting rights with respect to those shares unless both a
majority of all outstanding shares and a majority of all such shares excluding
all "interested shares" (in general, shares beneficially controlled by the
acquiring person or any officer or inside director of the subject corporation)
approve the acquisition. If the control shares are accorded voting rights, then
dissenters' rights are available under the Kansas Control Share Acquisitions Act
to stockholders who did not vote in favor of the control share acquisition and
who comply with certain prescribed procedures. If the stockholders vote not to
accord voting rights to the control shares, however, then the issuing
corporation has a 60-day option to redeem all such shares at market value.
 
OTHER MATTERS
 
     The Bank of New York serves as registrar and transfer agent for the Common
Stock and for the Class A $5.00 Cumulative Preferred Stock.
 
        DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS
 
     The Company may issue Stock Purchase Contracts, including contracts
obligating holders to purchase from the Company, and the Company to sell to the
holders, a specified number of shares of Common Stock at a future date or dates.
The consideration per share of Common Stock may be fixed at the time the Stock
Purchase Contracts are issued or may be determined by reference to a specific
formula set forth in the Stock
 
                                       32
<PAGE>   36
 
Purchase Contracts. The Stock Purchase Contracts may be issued separately or as
Stock Purchase Units consisting of a Stock Purchase Contract and Debt
Securities, Preferred Securities or debt obligations of third parties, including
U.S. Treasury securities, securing the holders' obligations to purchase the
Common Stock under the Stock Purchase Contracts. The Stock Purchase Contracts
may require the Company to make periodic payments to the holders of the Stock
Purchase Units or vice versa, and such payments may be unsecured or prefunded on
some basis. The Stock Purchase Contracts may require holders to secure their
obligations thereunder in a specified manner.
 
     The applicable Prospectus Supplement will describe the terms of any Stock
Purchase Contracts or Stock Purchase Units. The description in the Prospectus
Supplement will not necessarily be complete, and reference will be made to the
Stock Purchase Contracts, and, if applicable, collateral arrangements and
depositary arrangements, relating to such Stock Purchase Contracts or Stock
Purchase Units. Certain material United States federal income tax considerations
applicable to the Stock Purchase Units and the Stock Purchase Contracts will be
discussed in the Prospectus Supplement relating thereto.
 
                              BOOK-ENTRY ISSUANCE
 
     Unless otherwise specified in the applicable Prospectus Supplement, The
Depositary Trust Company ("DTC") will act as depositary for Securities issued in
the form of Global Securities. Such Securities will be issued only as
fully-registered securities registered in the name of Cede & Co. (DTC's
nominee). One or more fully-registered Global Securities will be issued for such
Securities representing in the aggregate the total number of such Securities,
and will be deposited with or on behalf of DTC.
 
     DTC is a limited purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its Participants deposit with DTC. DTC also facilitates
the settlement among Participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. Direct Participants include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations ("Direct Participants"). DTC is owned by a number of its
Direct Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others such as securities brokers and
dealers, banks and trust companies that clear through or maintain custodial
relationships with Direct Participants, either directly or indirectly ("Indirect
Participants"). The rules applicable to DTC and its Participants are on file
with the Commission.
 
     Purchases of Securities within the DTC system must be made by or through
Direct Participants, which will receive a credit for such Securities on DTC's
records. The ownership interest of each actual purchaser of each Security
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect
Participants' records. Beneficial Owners will not receive written confirmation
from DTC of their purchases, but Beneficial Owners are expected to receive
written confirmations providing details of the transactions, as well as periodic
statements of their holdings, from the Direct or Indirect Participants through
which the Beneficial Owners purchased Securities. Transfers of ownership
interests in Securities issued in the form of Global Securities are to be
accomplished by entries made on the books of Participants acting on behalf of
Beneficial Owners. Beneficial Owners will not receive certificates representing
their ownership interests in such Securities, except in the event that use of
the book-entry system for such Securities is discontinued.
 
     DTC has no knowledge of the actual Beneficial Owners of the Securities
issued in the form of Global Securities; DTC's records reflect only the identity
of the Direct Participants to whose accounts such Securities are credited, which
may or may not be the Beneficial Owners. The Participants will remain
responsible for keeping account of their holdings on behalf of their customers.
 
                                       33
<PAGE>   37
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices shall be sent to Cede & Co. as the registered holder of
Securities issued in the form of Global Securities. If less than all of a series
of such Securities are being redeemed, DTC's current practice is to determine by
lot the amount of the interest of each Direct Participant to be redeemed.
 
     Although voting with respect to Securities issued in the form of Global
Securities is limited to the holders of record of such Securities, in those
instances in which a vote is required, neither DTC nor Cede & Co. will itself
consent or vote with respect to such Securities. Under its usual procedures, DTC
would mail an omnibus proxy (the "Omnibus Proxy") to the issuer of such
Securities as soon as possible after the record date. The Omnibus Proxy assigns
Cede & Co.'s consenting or voting rights to those Direct Participants to whose
accounts such Securities are credited on the record date (identified in a
listing attached to the Omnibus Proxy).
 
     Payments in respect of Securities issued in the form of Global Securities
will be made by the issuer of such Securities to DTC. DTC's practice is to
credit Direct Participants' accounts on the relevant payment date in accordance
with their respective holdings shown on DTC's records unless DTC has reason to
believe that it will not receive payments on such payment date. Payments by
Participants to Beneficial Owners will be governed by standing instructions and
customary practices and will be the responsibility of such Participant and not
of DTC, the Institutional Trustee, either Trust or the Company, subject to any
statutory or regulatory requirements as may be in effect from time to time.
Payments to DTC are the responsibility of the issuer of the applicable
Securities, disbursement of such payments to Direct Participants is the
responsibility of DTC, and disbursements of such payments to the Beneficial
Owners is the responsibility of Direct and Indirect Participants.
 
     DTC may discontinue providing its services as depositary with respect to
any Securities at any time by giving reasonable notice to the issuer of such
Securities. In the event that a successor depositary is not obtained, individual
Security certificates representing such Securities are required to be printed
and delivered. The Company, at its option, may decide to discontinue use of the
system of book-entry transfers through DTC (or a successor depositary).
 
     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Trust and the Company believe to be
accurate, but the Trust and the Company assume no responsibility for the
accuracy thereof. Neither the Trust nor the Company has any responsibility for
the performance by DTC or its Participants of their respective obligations as
described herein or under the rules and procedures governing their respective
operations.
 
                              PLAN OF DISTRIBUTION
 
     Any of the Securities being offered hereby may be sold in any one or more
of the following ways from time to time: (i) through agents; (ii) to or through
underwriters; (iii) through dealers; and (iv) directly by the Company or, in the
case of Preferred Securities, by the Trust to purchasers.
 
     The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices.
 
     Offers to purchase Securities may be solicited by agents designated by the
Company from time to time. Any such agent involved in the offer or sale of the
Securities in respect of which this Prospectus is delivered will be named, and
any commissions payable by the Company or the Trust to such agent will be set
forth, in the applicable Prospectus Supplement. Unless otherwise indicated in
such Prospectus Supplement, any such agent will be acting on a reasonable best
efforts basis for the period of its appointment. Any such agent may be
 
                                       34
<PAGE>   38
 
deemed to be an underwriter, as that term is defined in the Securities Act, of
the Securities so offered and sold.
 
     If Securities are sold by means of an underwritten offering, the Company
and, in the case of an offering of Preferred Securities, the Trust will execute
an underwriting agreement with an underwriter or underwriters at the time an
agreement for such sale is reached, and the names of the specific managing
underwriter or underwriters, as well as any other underwriters, the respective
amounts underwritten and the terms of the transaction, including commissions,
discounts and any other compensation of the underwriters and dealers, if any,
will be set forth in the applicable Prospectus Supplement which will be used by
the underwriters to make resales of the Securities in respect of which this
Prospectus is being delivered to the public. If underwriters are utilized in the
sale of any Securities in respect of which this Prospectus is being delivered,
such Securities will be acquired by the underwriters for their own account and
may be resold from time to time in one or more transactions, including
negotiated transactions, at fixed public offering prices or at varying prices
determined by the underwriters at the time of sale. Securities may be offered to
the public either through underwriting syndicates represented by managing
underwriters or directly by one or more underwriters. If any underwriter or
underwriters are utilized in the sale of Securities, unless otherwise indicated
in the applicable Prospectus Supplement, the underwriting agreement will provide
that the obligations of the underwriters are subject to certain conditions
precedent and that the underwriters with respect to a sale of such Securities
will be obligated to purchase all such Securities if any are purchased.
 
     The Company or the Trust, as applicable, may grant to the underwriters
options to purchase additional Securities, to cover over-allotments, if any, at
the initial public offering price (with additional underwriting commissions or
discounts), as may be set forth in the Prospectus Supplement relating thereto.
If the Company or the Trust, as applicable, grants any over-allotment option,
the terms of such over-allotment option will be set forth in the Prospectus
Supplement for such Securities.
 
     If a dealer is utilized in the sale of the Securities in respect of which
this Prospectus is delivered, the Company or the Trust, as applicable, will sell
such Securities to the dealer as principal. The dealer may then resell such
Securities to the public at varying prices to be determined by such dealer at
the time of resale. Any such dealer may be deemed to be an underwriter, as such
term is defined in the Securities Act, of the Securities so offered and sold.
The name of the dealer and the terms of the transaction will be set forth in the
Prospectus Supplement relating thereto.
 
     Offers to purchase Securities may be solicited directly by the Company or
the Trust, as applicable, and the sale thereof may be made by the Company or the
Trust directly to institutional investors or others, who may be deemed to be
underwriters within the meaning of the Securities Act with respect to any resale
thereof. The terms of any such sales will be described in the Prospectus
Supplement relating thereto.
 
     Securities may also be offered and sold, if so indicated in the applicable
Prospectus Supplement, in connection with a remarketing upon their purchase, in
accordance with a redemption or repayment pursuant to their terms, or otherwise,
by one or more firms ("remarketing firms"), acting as principals for their own
accounts or as agents for the Company or the Trust, as applicable. Any
remarketing firm will be identified and the terms of its agreement, if any, with
the Company or the Trust and its compensation will be described in the
applicable Prospectus Supplement. Remarketing firms may be deemed to be
underwriters, as that term is defined in the Securities Act, in connection with
the Securities remarketed thereby.
 
     If so indicated in the applicable Prospectus Supplement, the Company or the
Trust, as applicable, may authorize agents and underwriters to solicit offers by
certain institutions to purchase Securities from the Company or the Trust at the
public offering price set forth in the applicable Prospectus Supplement pursuant
to delayed delivery contracts providing for payment and delivery on the date or
dates stated in the applicable Prospectus Supplement. Such delayed delivery
contracts will be subject to only those conditions set forth in the applicable
Prospectus Supplement. A commission indicated in the applicable Prospectus
supplement will be paid to underwriters and agents soliciting purchases of
Securities pursuant to delayed delivery contracts accepted by the Company or the
Trust, as applicable.

<PAGE>   39
 
     Agents, underwriters, dealers and remarketing firms may be entitled under
relevant agreements with the Company or the Trust, as applicable, to
indemnification by the Company or the Trust against certain liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which such agents, underwriters, dealers and remarketing firms may
be required to make in respect thereof.
 
     Each series of Securities will be a new issue and, other than the Common
Stock, which is listed on the New York Stock Exchange, will have no established
trading market. The Company may elect to list any series of Securities on an
exchange, and in the case of the Common Stock, on any additional exchange, but,
unless otherwise specified in the applicable Prospectus Supplement, the Company
shall not be obligated to do so. No assurance can be given as to the liquidity
of the trading market for any of the Securities.
 
     Agents, underwriters, dealers and remarketing firms may be customers of,
engage in transactions with, or perform services for, the Company and its
subsidiaries in the ordinary course of business.
 
                                 LEGAL MATTERS

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     K N is currently authorized by its Restated Articles of Incorporation, as
amended (the "K N Charter") to issue 50,000,000 shares of Common Stock, of which
32,024,557 were outstanding on December 31, 1997; 200,000 shares of Class A
Preferred Stock, no par value ("Class A Preferred Stock"), of which 70,000
shares were outstanding as Class A $5.00 Cumulative Preferred Stock on such
date; and 2,000,000 shares of Class B Preferred Stock, no par value ("Class B
Preferred Stock"), none of which were outstanding on such date.
 
     The Board of Directors of K N is authorized by the K N Charter to provide,
without further stockholder action, for the issuance of one or more series of
Class A Preferred Stock and Class B Preferred Stock. The Board of Directors has
the power to fix various terms with respect to each such series, including
voting power, designations, preferences, dividend rates, conversion and exchange
provisions, redemption provisions and, in the case of the Class B Preferred
Stock, the amounts which holders are entitled to receive upon any liquidation,
dissolution or winding up of K N. Class A Preferred Stock and Class B Preferred
Stock will rank prior to the Common Stock with respect to both dividends and
distribution of assets on liquidation, dissolution or winding up of K N.
 
     In the event of any liquidation, dissolution or winding up of K N, whether
voluntary or involuntary, the holders of shares of Class A Preferred Stock of
each series shall be entitled to receive in full out of the assets of K N the
sum of $100 per share of Class A Preferred Stock, plus any arrearages in
dividends thereon to the date fixed for the payment in liquidation, before any
distribution shall be made to the holders of shares of any stock junior to the
Class A Preferred Stock. K N may, at the option of the Board of Directors,
redeem the whole or any part of the Class A Preferred Stock, or of any series
thereof at any time or from time to time within the period during which such
stock is, according to the K N Charter, or the resolutions of the Board of
Directors providing for the issue thereof, redeemable, by paying the redemption
price thereof, including any arrearages in dividends thereon to the date fixed
for redemption. The Class A $5.00 Cumulative Preferred Stock is redeemable, in
whole or in part, at the option of K N at any time, or from time to time, at the
price of $105 per share plus accrued and unpaid dividends. This series has no
sinking fund requirements. Holders of shares of Class A $5.00 Cumulative
Preferred Stock are entitled to receive, when and as declared by the Board of
Directors of K N, cumulative preferential cash dividends at the annual rate of
$5.00 per share prior to the payment of any dividends or other distributions on
(or purchase or redemption of) the Class B Preferred Stock or the Common Stock.
 
     In the event of any liquidation, dissolution or winding up of K N, whether
voluntary or involuntary, the holders of shares of Class B Preferred Stock of
each series shall be entitled to receive, subject to the prior rights of the
holders of shares of Class A Preferred Stock, the full preferential amount fixed
by the K N Charter, or the resolutions of the Board of Directors providing for
the issue thereof, including any arrearages in dividends thereon to the date
fixed for the payment in liquidation, before any distribution shall be made to
the holders of shares of any stock junior to the Class B Preferred Stock.
Dividends may not be declared or paid or set apart for payment on any series of
Class B Preferred Stock, unless there shall be no arrearages in dividends on any
series of Class A Preferred Stock entitled to cumulative dividends for any past
dividend period and dividends in full for the current dividend period have been
paid or declared or set aside for payment on all Class A Preferred Stock.
 
     In addition, the holders of the Class A Preferred Stock then outstanding
have the right to vote separately as a class with respect to (i) certain
amendments to the K N Charter or the By-Laws of K N which adversely affect the
voting powers, rights or preferences of the holders of shares of Class A
Preferred Stock, (ii) the creation of any class of stock or any security
convertible into or exchangeable for or evidencing the right to purchase any
stock ranking prior to or on a parity with, either as to dividends or upon
liquidation, the Class A Preferred Stock, or (iii) certain mergers or
consolidations of K N with or into any other corporation. For such actions to be
taken by K N, including increasing the authorized amount of any class of stock
ranking prior to the Class A Preferred Stock, the affirmative vote of the
holders of at least 50% of the shares of the Class A Preferred Stock then
outstanding would be required. The affirmative vote of at least 50% of the
shares of any
 
                                        4
<PAGE>   44
 
series of Class A Preferred Stock then outstanding is required for K N to amend
the K N Charter or resolutions of the Board of Directors of K N providing for
the issue of such series of Class A Preferred Stock so as to affect adversely
the powers, preferences or rights of holders of Class A Preferred Stock of such
series. The holders of Class B Preferred Stock then outstanding also have the
right to a separate vote regarding (a) the events described in the first
sentence of this paragraph with regard to such Class B Preferred Stock,
requiring the affirmative vote of at least 50% of the shares of Class B
Preferred Stock then outstanding, and (b) amendments to the K N Charter, or to
resolutions of K N's Board of Directors providing for the issue of any series of
Class B Preferred Stock so as to affect adversely the powers, preferences or
rights of the holders of such series, requiring the affirmative vote of at least
50% of the shares of such series then outstanding.
 
     If dividends are in arrears on the shares of any series of Class A
Preferred Stock to which the following provisions are made applicable pursuant
to the K N Charter or resolutions of K N's Board of Directors providing for the
issue of any such series (i) in an aggregate amount equal to three but less than
six full quarterly dividends, then the holders of the shares of all such series
of Class A Preferred Stock have the exclusive right, voting separately as a
class and without regard to series, to elect directors constituting one-third of
K N's Board of Directors or (ii) in an aggregate amount equal to six full
quarterly dividends, then such holders have the exclusive right, voting
separately as a class and without regard to series, to elect directors
constituting one-half of K N's Board of Directors plus one additional director,
in each case until all arrearages in dividends and dividends in full for the
current quarterly period have been paid on or declared and set aside for payment
on the shares of such series. These provisions are applicable to the Class A
$5.00 Cumulative Preferred Stock. The holders of any outstanding Class B
Preferred Stock would have the right to elect directors of K N similar to the
Class A $5.00 Cumulative Preferred Stock in the event of nondeclaration of
dividends, for the periods described above, on the Class B Preferred Stock if
the holders of the Class A $5.00 Cumulative Preferred Stock are not then
entitled to elect directors as described above.
 
     All outstanding shares of Common Stock are, and any shares of Common Stock
newly issued under any Prospectus Supplement will be, validly issued, fully paid
and nonassessable. Holders of K N Common Stock and Class A $5.00 Cumulative
Preferred Stock are entitled to one vote for each share on all matters voted on
by stockholders. Holders of Common Stock, Class A Preferred Stock and Class B
Preferred Stock have no preemptive rights to subscribe for or purchase any
additional securities issued by K N. Subject to the preferential rights of the
holders of the Class A Preferred Stock and Class B Preferred Stock, the holders
of Common Stock are entitled to receive any dividends which may be declared by
the Board of Directors out of funds legally available therefor and to share pro
rata in the net assets of K N upon liquidation, dissolution or winding up.
Shares of Common Stock have no cumulative voting rights or redemption, sinking
fund or conversion privileges.
 
ANTI-TAKEOVER MATTERS
 
     Charter and By-laws.  Certain provisions of the K N Charter and the By-Laws
of K N could have the effect of preventing a change in control of K N in certain
situations. These provisions generally provide for (a) the classification of the
Board of Directors of K N into three classes of as nearly an equal number as
possible, having staggered terms of three years each; (b) the removal of
directors only for cause or by unanimous vote of the remaining members of the
Board of Directors; (c) the filling of any vacancy on the Board of Directors by
the remaining directors then in office; (d) the limitation of the number of
directors to a minimum of nine and a maximum of 15, with the exact number to be
determined by the Board of Directors; (e) increasing the stockholder vote
required to amend, repeal or adopt any provision inconsistent with the foregoing
provisions under (a), (b) and (d) above to two-thirds of the outstanding voting
securities of K N; (f) the requirement that certain business combinations or
transactions involving K N and any beneficial owner of more than 5% of the
outstanding voting securities of K N be approved by holders of at least
two-thirds of the outstanding voting securities of K N, including those held by
such beneficial owner, unless the business combination or transaction is (I)
approved by the Board of Directors before such beneficial owner became a holder
of more than 5% of K N's outstanding voting securities or (II) approved by
sufficient members of the Board of Directors to constitute a majority of the
members of the full Board of Directors in office prior to the time such
beneficial owner became a holder of more than 5% of K N's voting securities, or
(III) with an entity
 
                                        5
<PAGE>   45
 
of which a majority of the outstanding shares of voting securities is owned by K
N and its subsidiaries; (g) increasing the stockholder vote required to amend,
repeal or adopt any provision inconsistent with the foregoing provision under
(f) above to two-thirds or more of the then outstanding shares of voting
securities of K N; (h) the requirement that certain business combinations or
transactions involving K N and any beneficial owner of 10% or more of the
outstanding voting securities of K N be approved by holders of at least 80% of
the outstanding voting securities of K N, including those held by such
beneficial owner, unless (I) the business combination or transaction is approved
by three-fourths of the Board of Directors then in office who are not associated
with or related to anyone who beneficially owns, and do not themselves own, 10
percent or more of K N's voting securities or (II) certain conditions relating
generally to the fairness of the price to be received by stockholders of K N in
such business combination or transaction are satisfied; (i) increasing the
stockholder vote required to amend, repeal or adopt any provision inconsistent
with the foregoing provision under (h) above to 80% or more of the outstanding
voting securities of K N unless approved by an affirmative vote of three-fourths
of the Board of Directors then in office who are not associated with or related
to anyone who beneficially owns, and do not themselves own, 10% or more of K N's
voting securities; (j) certain procedural requirements for stockholder
nominations to the Board of Directors; and (k) the requirement that special
meetings of stockholders may only be called by stockholders owning 51% or more
of the outstanding voting securities of K N, by a majority of the Board of
Directors, the Chairman of the Board of Directors or the President of K N.
 
     Shareholder Rights Plan.  On August 17, 1995, the Board of Directors of K N
declared a dividend of one preferred share purchase right (a "Right") with
respect to each outstanding share of Common Stock held of record on September
15, 1995 or issued thereafter and prior to the date the Rights become
exercisable. Until the Rights become exercisable, they will be evidenced by
certificates for shares of Common Stock and will automatically trade with the
Common Stock. If and when the Rights become exercisable, Rights certificates
will be distributed and the Rights will become separately tradable. The full
terms of the Rights are set forth in the Rights Agreement dated as of August 21,
1995 (the "Rights Agreement"), between the Company and The Bank of New York, as
Rights Agent, a copy of which is filed as an exhibit to the Registration
Statement.
 
     Each Right entitles the holder thereof to purchase from the Company one
one-thousandth of a share of Class B Junior Participating Series Preferred
Stock, without par value (the "Preferred Shares"), for a price of $80 per one
one-thousandth of a Preferred Share (the "Purchase Price"), subject to
adjustment. The Rights become exercisable upon the earlier of (i) ten business
days following a public announcement that a person or group of affiliated or
associated persons has acquired beneficial ownership of 20% or more of the
outstanding voting shares of the Company or (ii) ten business days following the
commencement or announcement of an intention to commence a tender or exchange
offer the consummation of which would result in the beneficial ownership by a
person or group of 20% or more of the outstanding voting shares of the Company.
The Rights will expire on the later of September 15, 2005 or the third
anniversary of the date on which the Rights became exercisable (the "Final
Expiration Date"), unless the Final Expiration Date is extended or the Rights
are earlier redeemed or exchanged by the Company as described below.
 
     If a person or group were to acquire 20% or more of the voting shares of
the Company, each Right then outstanding (other than Rights beneficially owned
by the acquiring person, which would become null and void) would become a right
to buy that number of shares of Common Stock (or, under certain circumstances,
the equivalent number of one one-thousandths of a Preferred Share) that at the
time of such acquisition would have a market value of two times the Purchase
Price of the Right. If the Company were acquired in a merger or other business
combination transaction or more than 50% of its consolidated assets or earning
power were sold, proper provision will be made so that holder of a Right will
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase Price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction would have a market
value of two times the Purchase Price of the Right.
 
     At any time after the acquisition by a person or group of beneficial
ownership of 20% or more of the outstanding voting shares of the Company and
before the acquisition by a person or group of 50% or more of the outstanding
voting shares of the Company, the Board of Directors may, at its option, issue
shares of
 
                                        6
<PAGE>   46
 
Common Stock (or Preferred Shares) in mandatory redemption of, and in exchange
for, all or part of the then outstanding and exercisable Rights (other than
Rights owned by such person or group, which would become null and void) at an
exchange ratio of one share of Common Stock (or one one-thousandth of a
Preferred Share) for each Right, subject to adjustment. In addition, the Company
is entitled to redeem all of the outstanding Rights at a price of $0.01 per
Right at any time prior to the first public announcement that a person or group
has become the beneficial owner of 20% or more of the outstanding voting shares
of the Company.
 
     Until a Right is exercised, the holder thereof, as such, has no rights as a
stockholder of the Company, including, without limitation, the right to vote or
to receive dividends.
 
KANSAS BUSINESS COMBINATION ACT
 
     K N is subject to Sections 17-12,100 et seq. of the Kansas Statutes
Annotated (the "K.S.A."), which imposes a three-year moratorium on business
combinations between a Kansas corporation and an "interested stockholder" (in
general, a stockholder owning 15% or more of a corporation's outstanding voting
stock) or an affiliate or associate thereof unless (a) prior to an interested
stockholder becoming such, the board of directors of the corporation has
approved either the business combination or the transaction by which the
interested stockholder became such; (b) upon consummation of the transaction
resulting in an interested stockholder becoming such, the interested stockholder
owns 85% of the voting stock that was outstanding at the time the transaction
commenced (excluding, from the calculation of outstanding shares, shares
beneficially owned by management, directors and certain employees stock plans);
or (c) on or after the date an interested stockholder becomes such, the business
combination is approved by (i) the Board of Directors and (ii) the affirmative
vote of the holders of at least 66 2/3% of the outstanding shares (other than
those shares beneficially owned by the interested stockholder) at a meeting of
stockholders.
 
KANSAS CONTROL SHARE ACQUISITIONS ACT
 
     K N is also subject to Sections 17-1286 et seq. of the K.S.A. (the "Kansas
Control Share Acquisitions Act"), which applies to public corporations
incorporated in Kansas that have certain other connections with the state. The
Kansas Control Share Acquisitions Act relates principally to the acquisition of
"control shares" in such a corporation. Under the Kansas Control Share
Acquisitions Act, a control share acquisition is one that, except for the
operation of the Act, would raise the acquiring person's voting power in the
election of directors of the subject corporation to or above any of three
thresholds: one-fifth or more but less than one-third of all voting power;
one-third or more but less than a majority of all voting power; and at least a
majority of all voting power. Whenever a control share acquisition occurs, the
acquiring person has no voting rights with respect to those shares unless both a
majority of all outstanding shares and a majority of all such shares excluding
all "interested shares" (in general, shares beneficially controlled by the
acquiring person or any officer or inside director of the subject corporation)
approve the acquisition. If the control shares are accorded voting rights, then
dissenters' rights are available under the Kansas Control Share Acquisitions Act
to stockholders who did not vote in favor of the control share acquisition and
who comply with certain prescribed procedures. If the stockholders vote not to
accord voting rights to the control shares, however, then the issuing
corporation has a 60-day option to redeem all such shares at market value.
 
OTHER MATTERS
 
     The Bank of New York serves as registrar and transfer agent for the Common
Stock and for the Class A $5.00 Cumulative Preferred Stock.
 
                              SELLING STOCKHOLDER
 
     The Selling Stockholder is a Delaware corporation wholly owned by Cabot
Corporation ("Cabot") having its principal office in Boston, Massachusetts. On
July 13, 1994, K N acquired American Oil and Gas Corporation ("AOG") in a
stock-for-stock merger (the "Merger") accounted for as a pooling of interests.
Cabot was the largest stockholder of AOG prior to the Merger, owning
approximately 34.4% of the
 
                                        7
<PAGE>   47
 
outstanding shares of common stock of AOG at the time of the Merger plus
warrants to purchase approximately an additional 5.3% of such shares. Beginning
in June 1997, Cabot made capital contributions of all of its shares of Common
Stock to the Selling Stockholder.
 
     Cabot acquired its interest in AOG in 1989 when it sold its Texas gas
pipeline business to AOG. In connection with that transaction, Cabot and AOG
entered into a Standstill and Registration Rights Agreement, which, among other
things, entitled Cabot to three representatives on the board of directors of
AOG. At the time of the Merger, two nominees of Cabot were among AOG's eight
directors. Such Standstill and Registration Rights Agreement ceased to have
effect upon consummation of the Merger. Also in connection with the 1989
transaction, Cabot and AOG agreed to a liability sharing arrangement primarily
covering certain contingent liabilities and potential gas contract losses of the
acquired business. Pursuant to this liability sharing arrangement, Cabot and AOG
agreed to bear an equal amount of such liabilities up to $20 million each; Cabot
agreed to be solely responsible for these liabilities above that amount. All
matters pertaining to the liability sharing arrangement with Cabot were settled
in April 1997, and all final payments required thereby have been made. The
Company's final liability under the liability sharing arrangement with Cabot was
$5.6 million, which was previously recorded in connection with the acquisition
of AOG.
 
     AOG has asserted certain claims related to environmental matters against
Cabot under acquisition agreements related to assets previously owned by Cabot
or one or more of its subsidiaries (including assets acquired by AOG in the 1989
transaction referred to above and assets acquired by AOG from another company
which had previously purchased them from Cabot or one or more of its
subsidiaries). In January 1998, K N and Cabot agreed to submit such claims to
binding arbitration.
 
     Before its acquisition of AOG, K N had no material relationship with Cabot
or the Selling Stockholder. Pursuant to its merger agreement with AOG, at the
time of the Merger K N elected a designee of Cabot, John G. L. Cabot, as a
non-voting advisory director of K N, and agreed that for so long as Cabot
continued to own beneficially at least 10% of K N's voting Securities, Cabot
would have the right to designate one such advisory director. In addition, it
was agreed that if Cabot's beneficial ownership in K N was reduced below 10% but
continued over 5%, then the Board of Directors of K N would appoint Cabot's
advisory director as a full director with voting rights, and Cabot will be
entitled to have one designee for election to the Board of Directors of K N. In
April 1996, R. Gordon Shearer replaced John G. L. Cabot as Cabot's advisory
director, and in August 1996, when Cabot's beneficial ownership of K N voting
stock fell below 10%, Mr. Shearer was elected a director of K N. Mr. Shearer
resigned as a director in December 1997.

                              PLAN OF DISTRIBUTION
 
GENERAL
 
     The Selling Stockholder may sell Common Stock to or through underwriters or
dealers, and also may sell Common Stock directly to other purchasers or through
agents.
 
     The distribution of the Common Stock may be effected from time to time in
one or more transactions at a fixed price or prices, which may be changed, or at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices. If so indicated in the
Prospectus Supplement, the Selling Stockholder may sell Common Stock on the NYSE
or in the over-the-counter market, by methods that include block trades,
exchange or secondary distributions in accordance with NYSE rules and ordinary
brokerage transactions.
 
     In connection with the sale of Common Stock, underwriters may receive
compensation from the Selling Stockholder or purchasers of Common Stock for whom
they may act as agents in the form of discounts, concessions or commissions.
Underwriters, dealers and agents that participate in the distribution of Common
Stock may be deemed to be underwriters, and any discounts or commissions
received by them from the Selling Stockholder and any profit on the resale of
Common Stock by them may be deemed to be underwriting discounts and commissions
under the Securities Act. Any such person who may be deemed to be an underwriter
will be identified, and any such compensation received from the Selling
Stockholder, as the case may be, will be described, in the Prospectus
Supplement.
 
     Under agreements which may be entered into by the Company or the Selling
Stockholder, underwriters, dealers and agents who participate in the
distribution of Common Stock may be entitled to indemnification by the Company
or the Selling Stockholder, as the case may be, against or contribution toward
certain liabilities, including liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock will be passed upon for the Company by
Simpson Thacher & Bartlett (a partnership which includes professional
corporations), who may rely on the opinion of Polsinelli, White, Vardeman &
Shalton, Kansas City, Missouri, as to matters of Kansas law, and will be passed
upon for any agents, dealers or underwriters by counsel named in the applicable
Prospectus Supplement. Certain legal matters will be passed upon for the Selling
Stockholder by counsel named in the applicable Prospectus Supplement.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 17-6305 of the Kansas General Corporation Law provides that a
Kansas corporation shall have power to indemnify any person who was or is a
party, or is threatened to be made a party, to any threatened, pending or
completed action or suit (including an action by or in the right of the
corporation to procure a judgment in its favor) or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
person is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses actually and reasonably incurred by such
person in connection with the defense or settlement of such action or suit by or
in the right of the corporation, including attorney fees, and against expenses,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding, including
attorney fees, if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the
corporation; and, with respect to any criminal action or proceeding, had no
reasonable cause to believe such person's conduct was unlawful. Article Ninth of
the articles of incorporation of the Company requires the Company to provide
substantially the same indemnification of its directors and officers as that
authorized by the Kansas General Corporation Law.
 
     The Company has insurance policies which, among other things, include
liability insurance coverage for directors and officers, with a $200,000
corporate reimbursement deductible clause, under which directors and officers
are covered against "loss" arising from any claim or claims which may be made
against a director or officer by reason of any "wrongful act" in their
respective capacities as directors and officers. "Loss" is defined so as to
exclude, among other things, fines or penalties, as well as matters deemed
uninsurable under the law pursuant to which the policy is to be construed.
"Wrongful act" is defined to include any actual or alleged breach of duty,
neglect, error, misstatement, misleading statement or omission done or
wrongfully attempted. The policy also contains other specific definitions and
exclusions and provides an aggregate of $20,000,000 of insurance coverage.

ITEM 17.  UNDERTAKINGS.
 
     (a) The Company hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement; notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20 percent change
        in the maximum aggregate 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 paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
     the registration statement is on Form S-3, Form S-8 or Form F-3, 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
     Commission by the Company pursuant to Section 13 or Section 15(d) of the
     Exchange Act that are incorporated by reference in the registration
     statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered
 
                                      II-3
<PAGE>   52
 
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
          (4) For purposes of determining any liability under the Securities
     Act, 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.
 
          (5) For the purpose of determining any liability under the Securities
     Act, 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.
 
     (b) The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to any charter provision, by-law, contract, arrangement,
statute, or otherwise, the Company has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the successful defense of any action, suit or proceeding) is asserted
against the Company by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in the
opinion of counsel the matter has been settled by controlling precedent, submit
to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

         The Seller hereby represents and warrants to the Buyer as follows:

         2.1  Organization and Qualification.

              2.1.1 The Seller is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware.

              2.1.2 MidCon is a corporation duly organized, validly existing and

<PAGE>   10
MidCon is duly qualified as a foreign corporation to do business, and is in good
standing, in each jurisdiction where both (a) the character of its properties
owned or held under lease or the nature of its activities makes such
qualification necessary and (b) the failure to qualify would have a Material
Adverse Effect on MidCon and its Subsidiaries, taken as a whole. The Seller has
delivered to the Buyer a complete and correct copy of the Certificate of
Incorporation and By-laws of MidCon, each as in effect on the date hereof.

         2.2 Authority. The Seller has full corporate power to execute and
deliver this Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby on the part of the Seller have been duly and
validly authorized by the Seller's Board of Directors, and no other corporate
proceedings on the part of the Seller are necessary, as a matter of law or
otherwise, for the consummation of the transactions contemplated hereby. This
Agreement has been duly and validly executed and delivered by the Seller and is
a valid and binding agreement of the Seller, enforceable against it in
accordance with its terms.

         2.3  Noncontravention. Except as provided on Schedule 2.3, the
execution and delivery of this Agreement, the consummation of the transactions
contemplated hereby and the performance by the Seller of its obligations
hereunder will not:

         (a)  conflict with or result in any breach of any provision of the
Certificate of Incorporation or By-laws of the Seller, MidCon or any Significant
Subsidiary;


                                       3
<PAGE>   11
         (b)  require any consent, approval, order, authorization or permit of,
or registration, filing with or notification to, any Governmental Entity or any
private third party, except for filings, consents, approvals, orders,
authorizations or permits which (i) are required under the HSR Act; (ii) are
required by the FERC; (iii) are required by the Texas Railroad Commission; (iv)
are required by the Kansas Corporation Commission; (v) will not result in a
Material Adverse Effect on MidCon and its Subsidiaries, taken as a whole; or
(vi) will not prevent the consummation of the transactions contemplated hereby,
if not made or acquired;

         (c)  result in any violation or breach of, or constitute a default
under (or give rise to any right of termination, cancellation or acceleration or
guaranteed payments under or to a loss of a material benefit or result in the
creation or imposition of a lien under), any of the terms, conditions or
provisions of any note, lease, mortgage, indenture, license, agreement or other
instrument or obligation to which the Seller is a party or by which the
properties or assets of the Seller may be bound, or, to the Seller's Knowledge,
to which MidCon or any of its Significant Subsidiaries is a party or by which
the properties or assets of MidCon or its Significant Subsidiaries may be bound,
except for such violations, breaches, defaults, or rights of termination,
cancellation or acceleration, or losses which would not result in a Material
Adverse Effect on MidCon and its Subsidiaries, taken as a whole;

         (d)  violate the provisions of any order, writ, injunction, judgment,
decree, statute, rule or regulation applicable to the Seller, or to the Seller's
Knowledge, to MidCon or any of its Significant Subsidiaries, that would result
in a Material Adverse Effect on MidCon and its Subsidiaries, taken as a whole;
or


                                       4
<PAGE>   12
         (e)  result in the creation of any Encumbrance upon the Shares under
any agreement or instrument to which the Seller is a party or by which the
Seller is bound, or, to Seller's Knowledge, upon any of the properties or assets
of MidCon or any of its Significant Subsidiaries under any agreement or
instrument to which MidCon or its Significant Subsidiaries is a party or by
which MidCon or its Significant Subsidiaries is bound.

         2.4  MidCon's Capitalization. MidCon has an authorized capitalization
consisting solely of 1,400,000 shares of common stock, par value $.01 per share
("Common Stock"). There are 1,400,000 shares of Common Stock issued and
outstanding, all of which are owned, beneficially and of record, by the Seller
(the "Shares") free and clear of all Encumbrances except as set forth on
Schedule 2.3. The Shares have been validly issued, are fully paid and
nonassessable. No agreement or other document grants or imposes on any Shares
any right, preference, privilege or restriction with respect to the transaction
contemplated hereby (including, without limitation, any right of first refusal).

         2.5  Utility Status. Neither the Seller, MidCon nor any of its
Significant Subsidiaries is a "Holding Company" or a "Public Utility Company" or
a "Gas Utility Company" as those terms are defined in the PUHCA.

         2.6  Waiver by the MidCon ESOP Trust. The Seller has obtained a written
waiver by the MidCon ESOP Trust of all its rights to exchange the CMIC Preferred
Stock for, or to cause a third party to acquire, the Shares pursuant to the
MidCon ESOP Agreements.


                                       5
<PAGE>   13
         2.7  Finders and Brokers. No broker, finder or investment banker is
entitled to any brokerage, finder's or other similar fee or commission in
connection with the transactions contemplated by this Agreement as a result of
arrangements made by or on behalf of the Seller or MidCon other than (a) Merrill
Lynch & Co. and Credit Suisse First Boston Corporation, the fees of whom will be
paid by the Seller and (b) the agreements with the MidCon ESOP Trustee and its
advisors, which fees and expenses will be paid by MidCon.

         2.8  Investment Purpose. The Seller is acquiring the Substitute Note
for its own account and not with a view to any sale or distribution thereof in
violation of any securities laws. The Seller has no present intention of
selling, distributing or otherwise disposing of any portion of the Substitute
Note in violation of any such laws. The Seller acknowledges that the Substitute
Note has not been registered or qualified under the Securities Act or any state
securities laws and may not be sold, assigned, pledged or otherwise disposed of
in the absence of such registration unless an exemption from such registration
is available.

         2.9  MidCon Significant Subsidiaries. Schedule 2.9 sets forth for each
Significant Subsidiary (i) its name and jurisdiction of organization, (ii) the
number of shares of authorized capital stock of each class of its capital stock,
(iii) the number of issued and outstanding shares of each class of its capital
stock, (iv) the names of the holders of shares of each class of stock and the
number of shares held by such holder, and (v) the number of shares of its
capital stock held in treasury. Each of the Significant Subsidiaries is a
corporation, validly existing and in good standing under the laws of its
jurisdiction of incorporation, is qualified to do business as a foreign
corporation and is in good standing in each jurisdiction in which the character
of such 


                                       6
<PAGE>   14
Subsidiary's properties or the nature of its business makes such qualification
necessary, except in jurisdictions, if any, where the failure to be so qualified
would not result in a Material Adverse Effect on MidCon and its Subsidiaries,
taken as a whole. Each of the Significant Subsidiaries has the requisite
corporate power to own, use or lease its properties and to carry on its business
as it is now being conducted. All the issued and outstanding shares of capital
stock of each Significant Subsidiary have been duly authorized and are validly
issued, fully paid and nonassessable; and except as set forth on Schedule 2.9,
there are no outstanding or authorized rights of any Person that could require
any Significant Subsidiary to issue, sell or otherwise cause to become
outstanding any of its capital stock.

         2.10 Financial Statements. Schedule 2.10 sets forth the audited
consolidated financial statements of MidCon and its consolidated Subsidiaries
(including any related notes and schedules) for each of the three years ended
December 31, 1994, 1995 and 1996 and for the ten months ended October 31, 1997
(collectively, the "Financial Statements"). The Financial Statements have been
prepared in accordance with GAAP applied on a consistent basis and present
fairly in all material respects the consolidated financial position of MidCon
and its consolidated Subsidiaries as of the date thereof, and the consolidated
results of operations and cash flows of MidCon and its consolidated Subsidiaries
for the periods presented therein (except as may be indicated in the notes
thereto and subject, in the case of financial statements for the ten-month
period ended October 31, 1997, to normal and recurring year-end adjustments and
the absence of amounts for the comparable period in 1996).


                                       7
<PAGE>   15
         2.11 Seller's SEC Reports. The Seller files reports, statements and
schedules with the SEC pursuant to the Securities Exchange Act (collectively,
the "SEC Reports"). None of the SEC Reports, to the extent they refer to MidCon
and its Subsidiaries, contain, as of their respective dates, any untrue
statement of a material fact, or omit, as of their respective dates, to state a
fact required to be stated therein or necessary in order to make the statements
made therein, in each case, as it relates to MidCon and its Subsidiaries, in
light of the circumstances under which they were made, not misleading.

         2.12 Absence of Certain Changes or Events. Except as contemplated by
this Agreement, or as disclosed in the Financial Statements or Schedule 2.12, to
the Seller's Knowledge, since October 31, 1997, (a) MidCon and its Significant
Subsidiaries have conducted their respective businesses only in the ordinary
course, consistent with past practice during the immediately preceding twelve
month period, and (b) as of the date hereof there has not occurred or arisen any
event that has had or, insofar as reasonably can be foreseen, is likely in the
future to have, a Material Adverse Effect on MidCon and its Subsidiaries, taken
as a whole, other than events or developments generally affecting the industry
in which MidCon and its Subsidiaries operate.

         2.13 Litigation. Except as recorded or disclosed in the Financial
Statements or Schedule 2.13, to the Seller's Knowledge, as of the date hereof,

pending or threatened against MidCon or any of its Significant Subsidiaries
which would have a Material Adverse Effect on MidCon and its Subsidiaries, taken
as a whole.

<PAGE>   16
         2.14 Compliance with Law. Except as recorded or disclosed in the
Financial Statements or Schedule 2.14, to the Seller's Knowledge, neither MidCon
nor any of its Significant Subsidiaries is in violation of any federal, state,
local or foreign law, ordinance, regulation, judgment, order or decree, the
violation of which would have a Material Adverse Effect on MidCon and its
Subsidiaries, taken as a whole.

         2.15 Employees and Employee Benefit Matters. To the Seller's Knowledge,
(i) each "employee benefit plan", as defined in Section 3(3) of ERISA,
maintained by MidCon or its Significant Subsidiaries complies in all material
respects with all applicable requirements of ERISA and of the Code, and other

agents has, with respect to any employee benefit plan maintained by MidCon or
its Significant Subsidiaries, engaged in any "prohibited transaction," as such
term is defined in Section 4975 of the Code or Section 406 of ERISA, which would
result in any taxes or penalties on prohibited transactions under Section 4975
of the Code or under Section 502(i) of ERISA, which would have a Material
Adverse Effect on MidCon and its Subsidiaries, taken as a whole.

         2.16 Contracts. Schedule 2.16 sets forth a true and complete list of
each of the following contracts that are currently in effect and to which MidCon
or any of its Significant Subsidiaries is a party, or by which any of their

                                       10
<PAGE>   18
or default under any such contract, except such as would not have a Material
Adverse Effect on MidCon and its Subsidiaries, taken as a whole.

                  5.1.2    The Cash Management Agreement.

                           (a) Pre-closing Adjustment. The Seller shall, and
shall cause MidCon to, adjust the MidCon Loan and the OPC Loan balances
immediately prior to the Closing as follows:

                               (i) An amount equal to the net amount, if any, by
which the Current Assets of MidCon exceed the sum of (A) the Current Liabilities
of MidCon plus (B) twenty million dollars ($20 million) each as of December 31,
1997 as shown on the 1997 Financial Statements, shall be added to the balance of
the C Facility Loans under the Cash Management Agreement thereby constituting a
distribution by MidCon to the Seller evidenced as a payable by MidCon.


                                       23
<PAGE>   31
                               (ii) An amount equal to the net amount, if any,
by which the sum of (A) the Current Liabilities of MidCon plus (B) twenty
million dollars ($20 million) exceed the Current Assets of MidCon each as at
December 31, 1997 as shown on the 1997 Financial Statements, shall be added to
the balance of the B Facility Loans under the Cash Management Agreement, thereby
constituting a contribution to MidCon by the Seller evidenced as a receivable of
MidCon.

         In connection with determining Current Assets and Current Liabilities
as of December 31, 1997, any and all adjustments in accordance with GAAP to
reflect the consequences of the transactions pursuant to this Agreement shall be
excluded; provided, however, the Current Liabilities at December 31, 1997 shall
include all amounts payable by MidCon to the MidCon ESOP Trustee arising from
the sale of the Shares and shall exclude the principal on the ESOP Note payable
after December 31, 1997.

                           (b) Loan Balances at Closing. The balance of each of
the OPC Loans and the MidCon Loans as at Closing shall be calculated by
including all amounts accrued but not yet payable for the period elapsed up to
the Closing Date, which amounts will include (i) the accrued interest on the
Dividend Note although due after the Closing, (ii) the payment by, or on behalf
of, MidCon to the MidCon ESOP Trustee and its advisors, and (iii) the amount of
Taxes of all sorts accrued pursuant to Article VI.

                           (c) Payment for Loan Balances. Within 30 days after
the Closing, the Seller shall pay the amount, if any, by which the OPC Loans
outstanding as of the Closing exceed the MidCon Loans outstanding at such date
(each determined in accordance with 


                                       24
<PAGE>   32
Section 5.1.2(b)), plus accrued interest in accordance with the provisions of
the Cash Management Agreement (subject to the modifications pursuant to the
following) to the date of payment, as if a "Mandatory Prepayment" existed
pursuant to Section 5.6 of the Cash Management Agreement. The Seller shall, and
shall cause MidCon to, enter into an agreement that, except as provided in the
preceding sentence, (i) shall, at the Closing, terminate each of the respective
Facilities, all management of cash pursuant thereto and the covenants
thereunder, and (ii) shall terminate the Cash Management Agreement fully upon
completion of the foregoing payment so that it no longer governs the payment of
any amounts payable after the Closing pursuant to the contracts, agreements or
arrangements outstanding after the Closing Date by and between MidCon and its
Subsidiaries on the one hand and the Seller and its Subsidiaries (other than
MidCon and its Subsidiary) on the other hand and such amounts shall be payable
as provided in the contract, agreement or arrangement governing such payment.

                  5.1.3 Intercompany Agreements. The Seller shall, and shall
cause its Subsidiaries to, perform the Intercompany Agreements, as amended,
which continue in effect after the Closing.

                  5.1.4 Originator Receivables Sales Agreement. Immediately
prior to the Closing, the Seller shall cause its Subsidiaries to terminate the
Originator Receivables Sales Agreement as to MidCon and its Subsidiaries and
shall cause MidCon and its Subsidiaries to repurchase all of the receivables
previously sold by MidCon and its Subsidiaries to Occidental Receivables, Inc.
that have not been collected prior to the date of such repurchase.

                  5.1.5 Insurance. The Seller, at the Closing, shall cause
MidCon and its Subsidiaries to enter into a release substantially in the form of
Exhibit 5.1.5(a) (the "Insurance Release Agreement") with the Seller and its
Subsidiary, OPCAL Insurance, Inc. ("OPCAL"), for the release of the Seller and
OPCAL from any and all liability under policies underwritten by OPCAL and its
predecessor, Piper Indemnity, as more fully described in the Insurance Release
Agreement. At the Closing, the Seller, OPCAL and the insurance companies to be
parties thereto shall enter into a novation agreement substantially in the form
of Exhibit 5.1.5(b) (the "Insurance Novation Agreement") substituting the Buyer
for the Seller as indemnitor of the insurance companies with regard to the
specified fronting policies previously issued for MidCon and its Subsidiaries.
Except as provided in the preceding two sentences, the Seller shall cause each
of MidCon and its Subsidiaries to continue to have rights as an insured under
the Seller's insurance policies, subject, however, to the terms and conditions
set forth in each applicable insurance policy. MidCon and its Subsidiaries shall
no longer be an insured under the Seller's insurance for any occurrence after
the Closing.

                  5.1.6 1997 Financial Statements. The Seller shall cause MidCon
to provide the Buyer with the audited consolidated financial statements of
MidCon and its consolidated Subsidiaries (including any related notes and
schedules) for the year ended December 31, 1997 (the "1997 Financial
Statements") on or before February 15, 1998. The 1997 Financial Statements shall
be prepared in accordance with GAAP applied on a consistent basis and present
fairly in all material respects the consolidated financial position of MidCon
and its consolidated Subsidiaries as at December 31, 1997, and the consolidated
results of operations 


                                       26
<PAGE>   34
and cash flow of MidCon and its consolidated Subsidiaries for the periods
presented therein (except as may be indicated in the notes thereto).

         5.2      Covenants by the Buyer.

                  5.2.1 Payment of the Loan Balance. Within 30 days after the
Closing, the Buyer shall cause MidCon to pay the amount, if any, by which the
MidCon Loans outstanding as of the Closing exceed the OPC Loans outstanding at
such date (each determined in accordance with Section 5.1.2(b)), plus accrued
interest in accordance with the provisions of the Cash Management Agreement
(subject to the modification described in Section 5.1.2(c)) to the date of
payment to be prepaid as if a "Mandatory Prepayment" existed pursuant to Section
5.6 of the Cash Management Agreement.

                  5.2.2 ESOP Note and MidCon ESOP Plan.

                        The Buyer agrees that it shall not demand repayment of,
otherwise discharge, or permit any payment in respect of, the ESOP Note until a
date after the Closing Date and thereafter shall cooperate with the Seller in
the resolution of the MidCon ESOP Plan, including furnishing records necessary
in its administration.

                  5.2.3 Employees and Employee Benefit Plans.

                  (a) Effective as of the Closing Date, the Buyer shall cause
MidCon or its Subsidiaries to continue to compensate each Salaried Employee who
remains an employee of the Buyer or its Subsidiaries at salaries or hourly
rates, as the case may be, no lower than the lesser of (i) the salaries or
hourly rates of MidCon or its Subsidiaries in effect immediately 


                                       27
<PAGE>   35
prior to the Closing Date or (ii) the salaries or hourly rates payable to the
Buyer's employees in either case in similar jobs and locations.

                  (b) Notwithstanding subpart (a), if the Buyer or any of its
Subsidiaries terminates any Salaried Employee within three months of the
Closing, the Buyer or its Subsidiaries shall pay the terminated Salaried
Employee severance benefits no less than those provided under the Termination
Allowance Plan in effect on the date of this Agreement, provided, however, that
such severance benefits shall only be payable to the extent that such benefits
would have been payable under such Termination Allowance Plan. After a three
month period subsequent to the Closing, a Salaried Employee who is terminated
shall be entitled to severance benefits not less than those provided to
employees of the Buyer or its Subsidiaries with like job status and service.

                  (c) Except as provided in subsection (b) to this Section

and each Former Salaried Employee with "Buyer Benefit Plans", which shall mean
the benefit plans and programs under (i) Employee Plans and Agreements effective
immediately prior to the Closing Date, (ii) the Buyer's benefit plans and
programs applicable to employees of the Buyer in similar jobs, or (iii) a
combination of Employee Plans and Agreements and the Buyer's plans and programs,
the determination of which shall be at the sole discretion of the Buyer,
provided however, that such combination of Employee Plans and Agreements and the
Buyer's plans and programs shall be, at a minimum, comparable in type and
aggregate value to those plans and programs provided by the Buyer's benefit
plans and programs applicable to employees of the Buyer in 


                                       28
<PAGE>   36
similar jobs. In addition, the Buyer shall cause such Buyer Benefit Plans to
comply in form and operation in all material respects with the requirements of
ERISA and the Code.

                  (d) From and after the Closing, each Salaried Employee and
each Former Salaried Employee shall be eligible to participate in the Buyer
Benefit Plans in accordance with the terms and conditions thereof. Under such
Buyer Benefit Plans, which are Employee Welfare Benefit Plans, Salaried
Employees and Former Salaried Employees and their eligible dependents, if a

applicable, of the Seller or its Subsidiaries immediately prior to the Closing
(i) shall participate in such Buyer Benefit Plans as of the Closing Date, and
(ii) shall be deemed to satisfy any pre-existing condition limitations under
group medical, dental, life insurance or disability plans that shall be provided
after the Closing Date. In addition, amounts paid by such Salaried Employees and
Former Salaried Employees towards deductibles and copayment limitations under
the health plans of the Seller or its Subsidiaries shall be counted toward
meeting any similar deductible and copayment limitations under the health plans
that shall be provided under the Buyer Benefit Plans.

                  (e) The Buyer and its Subsidiaries shall recognize all service
credited for each of the Salaried Employees and Former Salaried Employees on the
records of the Seller or its Subsidiaries for purposes of eligibility for
benefits and vesting under the Buyer Benefit Plans and the level of benefits
under the Buyer Benefit Plans, but specifically excluding any benefit accrual
under any Buyer Benefit Plan that is a defined benefit pension plan.

<PAGE>   37
                  (f) From and after the Closing, Salaried Employees shall be
entitled to retain and take any vacation time accrued on MidCon's records as
payable to any Salaried Employee for which vacation time has not been taken
prior to the Closing Date.

                  (g) From and after the Closing, the Buyer shall, or shall
cause MidCon or its Subsidiaries, as applicable, to, comply with all the terms,
conditions, obligations, and benefits set forth in the Union Contract.

                  (h) From and after the Closing Date, MidCon and its
Subsidiaries shall cease participation in any and all Employee Plans and
Agreements sponsored or maintained by the Seller or its Subsidiaries. Except as
set forth on Schedule 5.2.3, the Buyer agrees that it shall cause MidCon and its
Subsidiaries, (i) to be solely responsible and to pay for, and (ii) to indemnify
and hold the Seller and its Subsidiaries harmless from, any and all costs,
damages, losses, expenses or other liabilities arising out of or relating to any
and all claims for welfare benefits (including health care continuation coverage
and retiree welfare benefits) under any of the Employee Plans and Agreements or
otherwise by any Employee, Former Salaried Employee, Former Union Employee or
dependent or beneficiary thereof, irrespective of when such claims were
incurred.

                  (i) Representatives of the Buyer shall be entitled to meet
with the Employees at mutually agreeable times prior to the Closing to explain
and answer questions about the conditions, policies and benefits of employment
by the Buyer or its Subsidiaries after the Closing. The Seller shall cooperate
with the Buyer until Closing in communicating to such Employees any additional
information concerning employment after the Closing which such 


                                       30
<PAGE>   38
Employees may seek, or which the Buyer may desire to provide, and during normal
business hours shall allow additional meetings by representatives of the Buyer
with such Employees upon the reasonable requests of the Buyer. In addition,
after the Closing, the Seller and the Buyer agree to furnish each other with
appropriate records for each of the Employees as may be necessary to assist in
proper benefit administration.

                  (j) The Buyer hereby assumes all liability for any alleged
failure to give, or to cause MidCon or any of its Subsidiaries to give, all
notices required by the U.S. Worker Adjustment and Retraining Notification Act
of 1988, as amended (the "WARN Act"), and any similar state law or regulation by
reason of events occurring after the Closing. The Buyer shall indemnify and hold
harmless the Seller and its Affiliates with respect to any and all claims
asserted under the WARN Act or any similar law or regulation because of a "plant
closing" or "mass layoff" with respect to MidCon or any of its Subsidiaries
occurring after the Closing. For purposes of this Agreement, the Closing Date
shall be the "effective date" for purposes of the WARN Act.

                  5.2.4 Intercompany Agreements. After the Closing, the Buyer
shall cause MidCon and its Subsidiaries to perform their obligations under any
Intercompany Agreements which continue in effect after the Closing.

                  5.2.5 Substitution of Undertakings. At the Closing, the Buyer
shall execute and deliver the Insurance Novation Agreement as more fully

terminated, released and discharged, on or prior to the Closing Date, in a
manner reasonably satisfactory to the Seller, any commitments, guarantees and
indemnities (including letters of credit, bonds, promissory notes, commitments,
or obligations of whatsoever nature to any Governmental Entity or any other
Person) of the Seller and each of its Affiliates for the direct and indirect
benefit of MidCon or any of its Subsidiaries as set forth on Schedule 5.2.5 and
all such other commitments, guarantees and indemnities provided by Seller in
accordance with the Cash Management Agreement (collectively "Commitments"). For
any Commitments for which the Buyer does not obtain a termination, discharge or
obtain a release of Seller and its Affiliates at or prior to the Closing, the
Buyer shall after the Closing cause MidCon to pay to the Seller the following
(for purposes of this Section 5.2.5 initial capitalized terms not defined in
this Agreement and "Letter of Credit" shall have the meaning set forth in the
Cash Management Agreement):

                           (a) A fee in an amount equal to 0.5% per annum on the
Average Balance of each outstanding Letter of Credit;

                           (b) A fee equal to 0.5% per annum on the Average
Balance of each Guarantee;

                           (c) All costs and expenses incurred by the Seller
under any Letters of Credit for MidCon Consol; and


                                       32
<PAGE>   40
                           (d) The amount of payments made by the Seller to or
on behalf of MidCon Consol under any Guarantee or Letter of Credit.

days after the last day of the month in which such costs and expenses were paid
or fees incurred and payments pursuant to clause (d) shall be made at the time
such payment is made by the Seller.

         The Buyer shall continue to use all commercially reasonable efforts to
obtain, in a manner satisfactory to the Seller, all terminations, releases and
discharges of any remaining Commitments as soon as practicable after the
Closing. The Seller shall have no obligation to extend or replace any of the
Commitments.

         The Buyer agrees to cause MidCon to indemnify and hold harmless the
Seller after the Closing from and against any and all claims, damages, losses,
liabilities, costs or expenses (including, without limitation, attorneys' fees
and costs) which the Seller may incur (or which may be claimed against the
Seller by any Person whomsoever) by reason of or in connection with the
guarantee, delivery or transfer of or payment under any Commitment, including
any claims, damages, losses, liabilities, costs or expenses which the Seller may
incur by reason of or in connection with the failure of any bank issuing any
such Letter of Credit to fulfill or to comply with its obligations under any
such Letter of Credit.

                           (a) The Buyer agrees that all rights to

its Subsidiaries as provided in their respective Certificates or Articles of
Incorporation or By-laws or otherwise, in each case, in effect as of the date
hereof with respect to matters occurring prior to the Closing Date shall survive
the Closing and shall continue in full force and effect. After the Closing Date,
the Buyer shall cause MidCon to indemnify, defend and hold harmless the present

liabilities, fees and expenses (including reasonable fees and disbursements of
counsel) and judgments, fines, losses, claims, liabilities and amounts paid in
settlement (provided that any such settlement is effected with the prior written
consent of the Buyer) arising out of actions or omissions occurring at or prior

its Subsidiaries Certificate or Articles of Incorporation or By-laws, in each
case as in effect at the date hereof, including provisions therein relating to
the advancement of expenses incurred in the defense of any action or suit;
provided, that nothing herein shall impair any rights or obligations of any
present or former directors or officers of MidCon or any of its Subsidiaries.

                           (b) The Buyer shall, or shall cause MidCon to, pay

                           (c) In the event MidCon, the Buyer or any of their
successors or assigns (i) consolidates with or merges into any other Person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any Person, then, and in each such case, proper
provisions shall be made so that the successors and assigns of MidCon or the
Buyer, as the case may be, shall assume the obligations of MidCon and the Buyer
set forth in this Section 5.2.6.

                           (d) The provisions of this Section 5.2.6 are intended

his or her heirs and representatives.

         5.3      Covenants of Both Parties.

                  5.3.1 Access and Information. The Seller shall afford to the
Buyer, and to the Buyer's accountants, counsel and other representatives, full
access, during normal business hours during the period prior to the Closing
Date, to all of MidCon's and its Subsidiaries' properties, books, contracts,
commitments and records and, during such period, Seller shall furnish promptly

received by MidCon or its Subsidiaries during such period pursuant to the
requirements of the FERC, and (b) all other information concerning the business,

<PAGE>   43
                  5.3.2 Further Action, Reasonable Efforts; Consents and
Approvals. Upon the terms and subject to the conditions hereof, each of the
Parties hereto shall use its commercially reasonable efforts to take, or cause
to be taken, all appropriate action, and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to cause
the conditions set forth in Section 4.2, Section 4.3 and Section 4.4 to be
satisfied and to consummate and make effective the transactions contemplated
hereby, including, without limitation, using commercially reasonable efforts to
obtain all licenses, permits, orders, declarations, consents, approvals,
authorizations, certificates, qualifications and orders of, and make all filings
and required submissions with, all Governmental Entities, and all shareholders,
lenders and partners of, and parties to contracts with, any of the Seller, the
Buyer, MidCon or any other Persons, in each case, as are necessary or desirable
for the consummation of the transactions contemplated hereby (collectively
"Consents"). The Seller shall, as soon as possible after the date hereof, but in
any event prior to the Closing, deliver to the Buyer copies of all Consents
obtained by the Seller. The Buyer shall, as soon as possible prior to the
Closing, deliver to the Seller copies of all Consents obtained by the Buyer. In
case at any time after the Closing Date any further action is necessary or
desirable to carry out the purposes of this Agreement, the Buyer and the Seller
shall use their commercially reasonable efforts to take all such action. Prior
to the Closing, each Party shall use its best efforts not to take any action, or
enter into any transaction, that would cause any of its representations or
warranties contained in this Agreement to be untrue.

                  5.3.3 Notice of Revisions. A Party (the "Notifying Party") may
elect at any time prior to the Closing to notify the other Party (the "Notified
Party") of any revisions to 


                                       36
<PAGE>   44
such Party's representations or warranties or a Schedule referred to therein. If
the Notified Party does not terminate this Agreement pursuant to Section 7.1
within five (5) Business Days after receipt of such notice, such written notice
will be deemed to qualify the representations and warranties, or amend the
Schedules, contained in Article II or III, as applicable, and to have cured any
misrepresentation or breach of representation, warranty or covenant that
otherwise might have existed hereunder by reason of the matter covered by such
revision. Notwithstanding the foregoing, if the Notifying Party delivers a
notice of revision pursuant to this Section less than five (5) Business Days
prior to the Closing Date, then the Closing Date automatically shall be extended
to the date which is five (5) Business Days from the date of the notice of
revision or if not a Business Day, then the Business Day immediately following
that date.

                  5.3.4 Substitute Note. At the Closing, the Seller shall assign
to the Buyer (a) the ESOP Note, and (b) by execution and delivery to the Buyer
of the Term Loan Assignment Agreement, all of the Seller's rights and
obligations under the Term Loan Agreement and, in exchange therefor, at the
Closing the Buyer shall execute and deliver to the Seller the Term Loan
Assignment Agreement and shall issue to the Seller either (i) a Substitute Note,
the prompt and complete payment and performance in full of which shall be
secured by Government Securities maturing as to principal and interest in such
amounts and at such times as are sufficient (without consideration of any
reinvestment of such interest and after payment of all Taxes or other charges or
assessments in respect of such Government Securities payable by the Buyer) to
provide U.S. legal tender to pay the principal of, and each installment of
interest on, such Substitute Note at least one day before the date on which any
such payment is


                                       37
<PAGE>   45
due and payable in accordance with the terms of such Substitute Note, (ii) a
Substitute Note, the payment of all interest and principal of which is secured
by one or more letters of credit, in form and substance satisfactory to the
Seller, issued by a bank or group of banks with each such bank either (a) having
an investment grade credit rating by either Standard & Poor's Corporation or
Moody's Investors Service, Inc., so long as neither of the above rating agencies
has provided a credit rating below investment grade, (b) having been agreed to
by the Seller or (c) if a bank is not such an investment grade credit, its
portion of the letter of credit can be fronted by a bank having such investment
grade credit or (iii) any combination of the foregoing, as the Buyer may elect,
provided that the aggregate original principal amount of all such Substitute
Notes is equal to the sum of (x) the outstanding unpaid principal balance of the
ESOP Note as of the Closing Date and (y) all accrued and unpaid interest on the
ESOP Note to and including the Closing Date. If the Buyer elects to deliver a
Substitute Note at the Closing that is secured by Government Securities, at the
Closing, the Buyer shall execute and deliver to the Seller a security agreement
and a control agreement, each in form and substance satisfactory to the Seller,
which provide the Seller with a valid, perfected, first priority security
interest in such Government Securities.

            5.3.5 Interim Services Agreement. The Seller and MidCon shall
terminate the Services Agreement effective as of the Closing with amounts due
thereunder accrued up to the Closing as provided in Section 5.1.2(b). The Seller

Seller and to the Buyer, in their respective sole discretion.



            5.3.6 Pipeline Lease and the Buyer's Pipeline Lease Guaranty. At the
Closing, the Buyer shall execute and deliver to the Seller a written guaranty
(the "Buyer's Pipeline Lease Guaranty"), pursuant to which the Buyer shall
irrevocably and unconditionally guarantee to the Pipeline Lessor the full and
timely performance, payment and discharge by the Pipeline Lessee of all
obligations and liabilities of the Pipeline Lessee under the Pipeline Lease. The
Buyer's Pipeline Lease Guaranty shall be substantially in the form of the
Pipeline Lease Guaranty, with the Buyer as guarantor; provided, however that
Section 11 thereof shall be of no force or effect as long as the Pipeline Lease
Guaranty is in full force and effect. At the request of the Buyer, the Seller
shall cause the Pipeline Lessor to agree to a termination of the Pipeline Lease
Guaranty if, concurrently therewith, the Buyer's Pipeline Lease Guaranty is
amended to include the Buyer's Pipeline Covenants for the benefit of the
Pipeline Lessor.

      At or prior to the Closing, the Seller shall cause the Pipeline Lessor and
the Pipeline Lessee to amend the Pipeline Lease to:

      (a) provide the Pipeline Lessee with an option to purchase the Leased
Property at a price equal to its fair market value upon termination of the
Pipeline Lease, and on other terms and conditions reasonably satisfactory to the
Buyer and the Seller and set forth in such amendment. The fair market value of
the Leased Property shall be determined by agreement between the Pipeline Lessor
and the Pipeline Lessee or if the Pipeline Lessor and the Pipeline Lessee can
not agree within a specific period before the date on which the Pipeline Lease
is to


                                       39
<PAGE>   47
terminate, then by a team of three independent appraisers each having
appropriate industry experience to make such a valuation, with one appraiser to
be selected by each of the Pipeline Lessor and the Pipeline Lessee, and the
third to be selected by the first two appraisers. The determination of the fair
market value shall be the value agreed by at least two of the appraisers;

      (b) permit assignment of the Pipeline Lease by the Pipeline Lessee if (i)
no event of default under the Pipeline Lease, and no event that, with the giving
of notice or the lapse of time or both, would be such an event of default, shall
have occurred and be continuing, (ii) the Pipeline Lessee pays the costs and
expenses of the Pipeline Lessor in reviewing such proposed assignment, and (iii)
the Person to whom the Pipeline Lessee assigns its rights under the Pipeline
Lease (the "Assignee") satisfies the following criteria: (x) fifty percent (50%)
or more of the Assignee's outstanding equity and voting interests is owned,
directly or indirectly, by the Pipeline Lessee or the Buyer; or (y) (1) the
Assignee is not affiliated with the Pipeline Lessee or the Buyer, (2) the
Assignee, or an entity that absolutely and unconditionally guarantees the
Assignee's obligations under the Pipeline Lease (the "Assignee's Guarantor"),
has a tangible net worth of not less than $100,000,000, and either has an Above
Investment Grade Credit Rating or, in the reasonable opinion of the Pipeline
Lessor, satisfies the minimum financial criteria then in effect for an Above
Investment Grade Credit Rating;

      (c) provide that the Pipeline Lessee and the Buyer shall be fully
discharged from their obligations under the Pipeline Lease and the Buyer's
Pipeline Lease Guaranty, respectively, with respect to events and obligations
occurring after the date of an assignment in


                                       40
<PAGE>   48
accordance with the foregoing clause (b) upon delivery to the Pipeline Lessor of
an assumption agreement, in form and substance reasonably satisfactory to the
Pipeline Lessor, pursuant to which the Assignee assumes all of the Pipeline
Lessee's liabilities and obligations under the Pipeline Lease including, without
limitation, all liability for the payment of any rent, termination values and
any other amounts owing by the Pipeline Lessee under the Pipeline Lease, which
assumption agreement shall include the Buyer's Pipeline Covenants for the
benefit of the Pipeline Lessor unless the Assignee's Guarantor delivers to the
Pipeline Lessor a written guaranty, in form and substance reasonably
satisfactory to the Pipeline Lessor, that includes the Buyer's Pipeline
Covenants for the benefit of the Pipeline Lessor.

      "Buyer's Pipeline Covenants" shall mean financial covenants that are at
least as restrictive as those contained in any indenture, bond, promissory note,
loan or credit agreement or other evidence of indebtedness of the Buyer from
time to time outstanding.

      "Leased Property" shall have the meaning set forth in the Pipeline
Lease.

      "Investment Grade Credit Rating" means, with respect to any Person, that
the credit rating assigned to such Person's senior unsubordinated long term
indebtedness by at least two Rating Agencies is at least BBB- (or its
equivalent) or better.

that the credit rating assigned to such Person's senior unsubordinated long term

      "Rating Agencies" shall mean any of Standard & Poor's Ratings Group,
Duff & Phelps Credit Rating Co. and Moody's Investors Service.

      Upon the incorporation by reference of covenants referred to in the
preceding sentence, the Seller shall cause MidCon to be fully discharged from
its obligations under the Pipeline Lease Guaranty.

            5.3.7 MidCon Power Services Corp. Unless the Seller and the Buyer
shall enter into mutually satisfactory arrangements with regard to the
operations and contracts of MidCon Power Services Corp. on or before the
Closing, the Seller shall cause (a) MidCon Gas Services Corp. to declare a
dividend of, and transfer immediately prior to the Closing, all of the
outstanding capital stock of MidCon Power Services Corp. to MidCon and (b)
MidCon to declare a dividend of, and transfer immediately prior to the Closing,
all of the outstanding capital stock of MidCon Power Services Corp. to the
Seller after transferring all employees, any tangible assets and any cash of
that corporation to MidCon Management Corp. The Seller and the Buyer hereby
agree to transfer to the Buyer the capital stock so transferred to the Seller
upon receipt of the FERC approval of the transfer of such capital stock
ownership to the Buyer. As a result of any such transfer, MidCon Power Services
Corp. shall be deleted from Schedule 2.9 and the Seller can amend the remaining
Schedules to reflect the transactions between MidCon and its Subsidiaries and
MidCon Power Services Corp. In the event, in the Seller's reasonable judgment
FERC approval of any of the transactions contemplated by this Section 5.3.7 is
necessary, which determination shall be made no later than December 31, 1997,
the Seller shall advise the Buyer of such conclusion together with supporting
basis therefor and the Parties agree to use their best efforts to agree whether
such conclusion is


                                       42
<PAGE>   50
correct. If such approval is required the Parties agree to file the documents
which are required to be filed with FERC as quickly as possible.

                                   ARTICLE VI

                                      TAXES

      6.1 Section 338(h)(10) Election. There will be no election under Section
338(h)(10) of the Code with respect to the purchase and sale of the Shares.

      6.2 Tax Sharing Agreement. The Seller shall cause the Tax Sharing
Agreement between the Seller and MidCon to be terminated as of the Closing Date;
provided, however, that notwithstanding such termination of the Tax Sharing
Agreement, its provisions will remain in effect with respect to any period of
time during the taxable year in which the termination occurs, for which period
the income of MidCon and its Subsidiaries must be included in the federal Tax
Returns or any state Tax Returns of the Seller. With respect to any matters
covered by this Article VI, the provisions and conditions set forth in this
Agreement shall control over any conflicting or contradicting provision or
condition in the Tax Sharing Agreement.

      6.3 Federal Income Tax Returns and Combined State Income Tax Returns for
Periods Through the Closing Date. The Seller will include the income of MidCon
and its Subsidiaries (including any deferred income triggered into income by
Reg. Sec. 1.1502-13 and Reg. Sec. 1.1502-14 and any excess loss accounts taken
into income under Reg. Sec. 1.1502-19) on the Seller's consolidated federal
income Tax Return and each combined state income


                                       43
<PAGE>   51
Tax Returns for all periods through the Closing Date and pay any federal and
state income Taxes attributable to such income. The allocation of such Tax
liability between the Seller, on one hand, and MidCon and its Subsidiaries, on
the other hand, will be governed by the provisions of the Tax Sharing Agreement.
MidCon and its Subsidiaries will furnish Tax information to the Seller for
inclusion in the Seller's federal consolidated income Tax Return and each
combined state income Tax Return for the period which ends on the Closing Date
in accordance with MidCon's past custom and practice, and the Buyer will bear
the cost of complying with this provision. The income of MidCon and its
Subsidiaries will be allocated between the period up to and including the
Closing Date and the period after the Closing Date by closing the books of
MidCon and its Subsidiaries as of the end of the Closing Date.

      6.4 No Adjustment of MidCon Tax Liability for the Taxable Year Ending
December 31, 1997. The liability of MidCon and its Subsidiaries for consolidated
federal and combined state income Taxes with respect to the Taxable Year ending
December 31, 1997, as recorded on the 1997 Financial Statements, shall not be
adjusted to reflect the actual Tax liability reported on the applicable Tax
Returns as filed, and the provisions of Section V of the Tax Sharing Agreement
to the contrary shall not apply. For purposes of calculating the Tax liability
of MidCon and its Subsidiaries under the Tax Sharing Agreement for any Tax year
for which the Tax Sharing Agreement remains in effect under Section 6.2 of this
Agreement, tax attributes which carry forward from the Tax year ending December
31, 1997, shall not be adjusted to reflect amounts reported on the applicable
Tax Returns as filed.

the Seller Affiliated Group for the taxable period ending on the Closing
Date, including any portion of deferred income triggered into income by Reg.
Sec. 1.1502-13 and Reg. Sec. 1.1502-14 and excess loss accounts taken into
income under Reg. Sec. 1.1502-19 to be borne by MidCon and its Subsidiaries,
with such amount to be determined by applying the provisions of the Tax
Sharing Agreement.

      6.6 Separate State, Local, Foreign Income Tax Returns. The Seller shall
file, or cause to be filed, all separate state, local and foreign income Tax
Returns for MidCon and its Subsidiaries for which the Tax year ends on the
Closing Date. The Buyer will file, or cause to be filed, all separate state,
local and foreign income Tax Returns for MidCon and its Subsidiaries for which

liability for taxes on or measured by net income required to be reported on any
state, local or foreign Tax Return required to be filed by any of MidCon and its
Subsidiaries after the Closing Date which includes tax items for a period which
begins before and ends after the Closing shall be allocated between the portion
of such period ending on the Closing Date and the portion of such period
beginning on the date after the Closing Date on the basis of the taxable income
or loss of MidCon and its Subsidiaries as determined from the books and records
of the relevant entity for such partial period.

<PAGE>   53
      6.7 Sales and Property Taxes. The amount of any liability for real and
personal property taxes, business license taxes, ad valorem taxes or any similar
taxes based on the ownership of property payable with respect to assets of the
Business for a period which begins before and ends after the Closing Date shall

the portion beginning on the day after the Closing Date on a per diem basis. The
amount of any liability for sales taxes, gross receipts taxes, ad valorem taxes,
transfer taxes or other similar taxes based on the proceeds of identifiable
transactions or units of production payable by any of MidCon and its
Subsidiaries after the Closing Date for a period which begins before and ends
after the Closing Date shall be apportioned between the portion of such period
ending on the Closing Date and the portion of such period beginning on the day
after the Closing Date on the basis of the actual activities of MidCon and its
Subsidiaries as determined from the books and records of the relevant entity for
such partial period.

      6.8 State Franchise Taxes. The Buyer shall file, or cause to be filed, all
separate state franchise Tax Returns for MidCon and its Subsidiaries for which
the franchise tax measurement period begins before and ends after the Closing
Date. The Seller shall be responsible for any liability attributable to that
portion of such measurement period ending on the Closing Date. The Buyer shall

      6.9 Adjustment Upon Leaving Consolidation. Section VII of the Tax Sharing
Agreement is incorporated by reference and any payments thereunder shall be made
within sixty (60) days after the filing of the applicable federal and state Tax
Returns. Adjustments to or additional payments shall be made, as needed, by
reason of amended returns, claims for refund or audits by a taxing authority
with respect to any Tax year for which the Tax Sharing Agreement remains in
effect after the Closing Date.

      6.10 Sales and Transfer Taxes with Respect to this Transaction. All sales,
gross receipts, or other similar transfer taxes, if any (including all stock

transactions contemplated hereby shall be borne by the Buyer. The Buyer shall at
its expense file all necessary tax returns and other documentation in respect to
any such taxes.

      6.11 Cooperation. The Seller and the Buyer shall (i) each provide the
other, and the Buyer shall cause MidCon and its Subsidiaries to provide the
Seller, with such assistance as may reasonably be requested by any of them in
connection with the preparation of any Tax Return, audit or other examination by
any taxing authority or judicial or administrative proceedings relating to
liability for Taxes, (ii) each retain and provide the other with any material
records or information which may be relevant to such Tax Return, audit or
examination, proceeding or determination, and (iii) each provide the other with
any amount required to be shown on any Tax Return of the other for any period.
The Party requesting assistance hereunder shall reimburse the other for
reasonable out-of-pocket expenses incurred in providing such assistance to the
extent such expenses exceed an aggregate amount of



                                       47
<PAGE>   55
$50,000. Without limiting the generality of the foregoing, the Buyer shall
retain, and shall cause MidCon and its Subsidiaries to retain until the
applicable statutes of limitations (including any extensions) have expired,
copies of all Tax Returns, supporting work schedules and other records or
information in its possession which may be relevant to such returns for all
taxable periods from January 1, 1990 to the Closing Date, inclusive, and shall
not destroy or otherwise dispose of any such records without first providing the
Seller with an opportunity to review and copy the same. Following the Closing
Date, the Seller shall forward to the Buyer all Tax statements received by the
Seller with respect to the assets of the Business for any period that begins
before and ends after the Closing Date within thirty (30) days after its receipt
thereof.

      6.12 Tax Proceedings. Following the Closing Date, the Seller shall control
the conduct of all stages of any audit or other administrative or judicial
proceeding with respect to Taxes reported on any Tax Return filed by the Seller
or any Affiliate of the Seller or on any Tax Return filed by MidCon and its
Subsidiaries for any taxable period ending on or prior to the Closing Date. The
Buyer shall control the conduct of all other audits or administrative or
judicial proceedings with respect to the Tax liability of any of MidCon and its
Subsidiaries.

      6.13 Carrybacks. Except for carrybacks into the Seller's consolidated Tax
Return for the annual tax period ending December 31, 1997, the Seller shall
within 30 days pay to the Buyer any Tax refund resulting from a carryback of a
post-acquisition Tax attribute of any of MidCon and Subsidiaries into the Seller
consolidated Tax Return in all cases where MidCon and Subsidiaries cannot elect
to waive a carryback. Such Tax attributes will be considered to


                                       48
<PAGE>   56
produce a refund (or reduce Tax liability) only after all Tax attributes of the
Seller and other members of the Seller Affiliated Group have been used or deemed
used. The Seller shall cooperate with MidCon and its Subsidiaries in obtaining
such refunds, including through the filing of amended Tax Returns or refund
claims. The Buyer agrees to indemnify the Seller for any Taxes resulting from
the disallowance of such post-acquisition Tax attribute on audit or otherwise.

year tax returns which have been filed prior to the date hereof as they relate
specifically to MidCon without prior consultation with the Buyer.

            (a)   The Buyer and the Seller may terminate this Agreement by
mutual written consent.

            (b) Subject to the provisions of Section 7.2, (i) by the Seller if

have been satisfied or waived by the Termination Date and (ii) by the Buyer if
one or more of the conditions set forth in Section 4.2 or Section 4.4 shall not

condition, which is to be


                                       50

the failure to obtain any Consent from a Governmental Entity pursuant to the HSR
Act), the Buyer shall pay the Seller the amount of $100 million which the
Parties agree reflects compensation for the Seller's loss of opportunity to sell
the Shares to another person in a timely manner, and

            (ii) if this Agreement is terminated by the Buyer because of the
Seller's failure to perform or comply with any covenant, or satisfy any
condition, which is to be performed or complied with or satisfied at or prior to
the Closing (which shall not include the failure to obtain any necessary Consent
from a Governmental Entity pursuant to the HSR Act or by the FERC), the Seller
shall pay the Buyer the amount of $50 million which the Parties agree reflects
compensation for the Buyer's loss of opportunity to purchase the Shares in a
timely manner.

      Each Party's right of termination under Section 7.1 is in addition to any
other rights it may have under this Agreement or otherwise, and the exercise of
a right of termination will not be an election of remedies except if the Party
shall receive the compensation provided in the preceding sentence.

attorneys, accountants or other agents and experts reasonably incident to
matters indemnified against and the enforcement of such indemnity; provided,
however, that neither Buyer Indemnitees nor Seller Indemnitees shall be entitled

damages. The losses, liabilities, damages, costs and expenses included in the
indemnity provided for by each of the foregoing Sections of this Article VIII
are herein collectively called "Damages".


                                       55
<PAGE>   63
            8.4.2 The amount claimed by an Indemnified Person to be owing as
described in each such Section, together with a list identifying to the extent
reasonably possible each separate item of loss, liability, damage, cost or
expense for which payment is so claimed, shall be set forth by such Person in a
statement delivered to the indemnifying Party setting forth the details of and
the basis for such claim ("Claim Notice") and shall be paid by such indemnifying
Party, as and to the extent required herein, within 30 days after receipt of
such Claim Notice or, if the indemnifying Party raises reasonable objection
thereto within such 30 days, then whenever a determination as to whether the
Indemnified Person is entitled to indemnification hereunder shall have occurred

brought against any Indemnified Person by any third party, which action, suit or
proceeding, if determined adversely to the interests of such Indemnified Person,
would entitle such Indemnified Person to indemnity pursuant to the provisions of
Section 8.2 or Section 8.3, if the Claim Notice has been timely given pursuant
to Section 8.4.3, such Indemnified Person shall reasonably promptly notify the
indemnifying Party of the same in writing, but any failure to so notify shall
not relieve the applicable indemnifying Party from any liability which it may
have to such Indemnified Person under such Section 8.2 or Section 8.3 unless
such failure would prejudice materially the rights of the Party entitled to
receive such notification. The Person seeking indemnification pursuant to the
provisions of this Article VIII shall have the right, at its sole cost and
expense, to participate in any legal action for which indemnification shall be
sought. However, the Party from whom indemnification shall be sought shall have
