NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       General

As used herein, "K N" or "the Company" refers to K N Energy, Inc. and its
consolidated subsidiaries unless the context otherwise requires. In the opinion
of Management, all adjustments necessary for a fair presentation of the results
for the unaudited interim periods have been made. Except as explicitly noted,
these adjustments consist solely of normal recurring accruals. Certain prior
period amounts have been reclassified to conform with the current presentation.

2.       Acquisitions and Divestiture

On April 23, 1998, K N announced that it had agreed to purchase partnership
interests in four independent power plants in Colorado from Denver-based Thermo
Cos. ("Thermo"), representing approximately 380 megawatts of electric generation
capacity and access to approximately 130 Bcf of natural gas reserves. These
generating facilities are located in Fort Lupton (272 megawatts) and Greeley
(108 megawatts) and sell their power output to Public Service Co. of Colorado
under long-term contracts. The purchase, subject to the completion of certain
agreements involving an existing partner in certain of the generating
facilities, is expected to be paid for over a three-year period, with the
initial payment of $35 million to be made using 100% K N common stock and the
remaining two payments (in 1999 and 2000) being a combination of cash and K N
common stock as agreed to by the parties, with the default mix being 50% stock
and 50% cash.

In March 1998, K N completed the sale of its Kansas retail natural gas
distribution properties, located in 58 Kansas communities and serving
approximately 30,000 residential, commercial and industrial customers, to
Midwest Energy, Inc., a customer-owned cooperative based in Hays, Kansas. K N
received approximately $24 million in cash in conjunction with the sale and
recorded a pre-tax gain of approximately $8.5 million (approximately $5.5
million or $0.15 per diluted share after tax). Concurrently with the sale, K N
received approximately $27.5 million in cash in exchange for the release of the
purchaser from certain contractual gas purchase obligations, which amount will
be amortized by K N over a period of years as the associated volumes are sold.

On January 30, 1998, pursuant to a definitive stock purchase agreement (the
"Agreement"), K N acquired all of the outstanding shares of capital stock of
MidCon Corp. ("MidCon") from Occidental Petroleum Corporation ("Occidental") for
$2.1 billion in cash and the assumption of a $1.39 billion note (the "Substitute
Note"), at which time MidCon became a wholly owned subsidiary of K N Energy,
Inc. (the "Acquisition"). The Substitute Note bears interest at 5.798%, is due
January 4, 1999, and is required to be collateralized by U.S. government
securities, letters of credit or a combination thereof. In conjunction with the
Acquisition, K N also assumed MidCon's obligation to lease the MidCon Texas
intrastate pipeline system under a 30-year operating lease, requiring average
annual lease payments of approximately $30 million. The Acquisition was
initially financed through a combination of commitments referred to as the bank
facility (see Note 3).

MidCon is engaged in the purchase, gathering, processing, transmission, storage
and sale of natural gas to utilities, municipalities, and industrial and
commercial users. Prior to the acquisition, MidCon also purchased electricity
from electric utilities and other electric power producers and marketers and
resold the electricity to wholesale and end-use customers. MidCon's pipeline
subsidiaries operate over 13,000 miles of natural gas pipelines located in the
center of the North American pipeline grid, with access to major supply and
market

                                                                       Form 10-Q

areas. MidCon is also one of the nation's largest natural gas storage operators
and owns and operates several natural gas gathering and natural gas processing
facilities.

The Acquisition was accounted for as a purchase for accounting purposes and,
accordingly, the MidCon assets acquired and liabilities assumed have been
preliminarily recorded at their respective estimated fair market values as of
the acquisition date. The final fair market values will be assigned after
completion of a more extensive review of the relevant assets, liabilities and
issues identified as of the acquisition date, and may differ materially from the
preliminary values. The preliminary allocation of purchase price resulted in the
recognition of a gas plant acquisition adjustment of approximately $4.3 billion,
representing the excess of the assigned fair market value of the assets of
Natural Gas Pipeline Company of America ("NGPL") over its historical cost for
ratemaking purposes. This gas plant acquisition adjustment, none of which is
currently being recognized for rate-making purposes, is being amortized over 36
years, approximately the estimated remaining useful life of NGPL's interstate
pipeline system and, for the quarter ended March 31, 1998, approximately $19.8
million was charged to expense (representing the two months subsequent to the
Acquisition). The assets, liabilities and results of operations of MidCon are
included with those of the Company beginning with the acquisition date.

The following pro forma information gives effect to the acquisition of MidCon as
if the business combination had occurred at the beginning of each period
presented. The pro forma adjustments which have been made are based on a
preliminary allocation of the purchase price to assets acquired and liabilities
assumed and do not reflect adjustments for anticipated operating efficiencies
and cost savings which K N expects to achieve in conjunction with the
acquisition. In addition, no pro forma adjustments have been made for the
post-acquisition refinancings completed by K N. This unaudited pro forma
information should be read in conjunction with the accompanying interim
Consolidated Financial Statements, Management's Discussion and Analysis of
Financial Condition and Results of Operations and with the previously-filed
unaudited pro forma consolidated financial statements and related notes. This
pro forma information is not necessarily indicative of the financial results
which would have occurred had the Acquisition taken place on the dates
indicated, nor is it necessarily indicative of future financial results.

In December 1997, K N acquired Interenergy Corporation ("Interenergy"), a
diversified energy company involved with natural gas gathering, processing and
marketing in the Rocky Mountain and mid-continent states. In a transaction
accounted for as a purchase, K N exchanged 544,604 shares of K N common stock
for all the outstanding shares of Interenergy and assumed Interenergy's debt.
Also in December 1997, K N purchased an equity interest in Red Cedar Gathering
Company ("Red Cedar"), a gathering system located in the northern San Juan Basin
on the Southern Ute Indian Reservation in La Plata County, Colorado.
Red Cedar is jointly-owned by the Southern Ute Indian Tribe.

In March 1997, K N completed its purchase of several Enron Corporation
subsidiaries that owned or operated the Bushton natural gas processing facility
located in Ellsworth County, Kansas, and other Hugoton Basin gathering assets
located in Kansas and Oklahoma. The Company assumed operation of these
facilities effective April 1, 1997, and has accounted for this transaction as a
purchase. K N leases the processing facilities at Bushton under operating leases
requiring semi-annual payments averaging $23.1 million per annum for the
remaining term of the leases. Under the terms of these leases, K N has the
option of terminating the leases and/or buying the assets at any time after
November 2003, and extending the leases beyond May 2012, the scheduled
termination date. In addition, K N may purchase the processing facilities upon
termination of the leases.

3.       Business Segments

K N Energy, Inc. has adopted a strategy of extracting profit from the energy
value stream which extends from the purchase or production of the fuel through
the sale of the energy to the end-user. Consistent with this strategy, K N
manages its business and has segregated its activities into three business
segments, "Upstream", "Midstream" and "Downstream", based on where in the value
stream such activities are conducted. In general, these segments are also
differentiated by the nature of their processes, their principal suppliers and
their target markets and customers. The Company's Upstream operations consist of
(i) natural gas gathering, (ii) natural gas processing and (iii) natural gas
liquids ("NGLs") extraction and marketing; Midstream operations consist of
transportation, storage and bundled sales transactions for K N's interstate and
intrastate pipelines; Downstream operations consist of energy marketing and
regulated natural gas distribution.

The accounting policies applied in the generation of segment information are
generally the same as those described in the summary of significant accounting
policies in K N's 1997 Report on Form 10-K except that, in general, items below
the "Operating Income" line are either not allocated to business segments or are
not considered by Management in its evaluation of business unit performance. In
addition, certain items included in operating income (such as the merger-related
costs included in the first quarter of 1998) are not allocated to individual
business segments. With adjustment for these items, K N currently evaluates
business segment performance primarily based on operating income in relation to
the level of capital employed. In general, intersegment sales are accounted for
at market prices, while asset transfers are made at either market value or, in
some instances, book value. For comparative purposes, prior period results and
balances have been reclassified to conform to the current presentation.

4.       Financing

The total amount of funds required by K N to complete the Acquisition, pay
related fees and expenses and to repay borrowings under K N's existing credit
facility was approximately $2,518 million which was financed through borrowings
under credit agreements dated January 30, 1998 (the "Bank Facility") among K N,
Morgan Guaranty Trust Company of New York and a syndicate of other lenders. A
working capital facility replaced the revolving credit agreement previously in
place (the "Pre-Acquisition Facility"). An acquisition facility was also part of
the overall Bank Facility structure. See Note 8(A) of Notes to Consolidated
Financial Statements on pages 41-42 of K N's 1997 Annual Report on Form 10-K for
additional information regarding the Bank Facility and the Pre-Acquisition
Facility. In addition to the working capital and acquisition components of the
Bank Facility explained preceding, K N assumed a short-term note for $1,395
million (the "Substitute Note") which, pursuant to the Agreement, was initially
collateralized by letters of credit issued under a commitment for that purpose
within the Bank Facility.

In March 1998, K N received net proceeds of approximately $624.6 million from an
underwritten public offering of 12,500,000 shares of K N common stock and
approximately $2,341.5 million from the concurrent underwritten public offerings
of senior debt securities of varying maturities totaling $2.35 billion. The net
proceeds from these offerings were used to refinance borrowings under the Bank
Facility and to purchase U.S. government securities to replace a portion of the
letters of credit that collateralized the Substitute Note.

Following are the principal amounts, maturity dates and coupon rates for the
senior debt securities issued:

The 2003 Senior Notes and the 2005 Senior Notes are not redeemable prior to
maturity. The 2008 Senior Notes, 2028 Senior Debentures and 2098 Senior
Debentures are redeemable as a whole or in part, at the option of the Company at
any time, at redemption prices defined in the associated prospectus supplement.
The Reset Put Securities due March 1, 2021 (the "2021 REPS") are subject to
mandatory redemption from the then-existing holders on March 1, 2001 either (i)
through the exercise of a call option by Morgan Stanley & Co. International
Limited (the "Callholder") or (ii) in the event the Callholder does not exercise
the call option, the automatic exercise of a mandatory put by First Trust
National Association on behalf of the holders. The $12 million of proceeds
received by K N from the Callholder as consideration for the call option are
being amortized as an adjustment to the effective interest rate on the 2021
REPS. If the Callholder elects to exercise the call option, the interest rate
will be reset at that time.

In April 1998, K N sold $175 million of 7.63% Capital Securities (the "Capital
Securities") due April 15, 2028, in an underwritten public offering. The sale
was effected through a wholly owned business trust, K N Capital Trust III (the
"Trust"). The Company used the net proceeds from the offering to purchase U.S.
government securities to replace a portion of the letters of credit that
collateralized the Substitute Note.

The financial statements of the Trust will be consolidated into the Company's
consolidated financial statements, with the Capital Securities treated as a
minority interest and included in the Company's consolidated balance sheet under
the caption "K N-Obligated Mandatorily Redeemable Preferred Capital Trust
Securities of Subsidiary Trust Holding Solely Debentures of K N."

5.       Comprehensive Income

Statement of Financial Accounting Standards No. 130, "Reporting of Comprehensive
Income", effective for fiscal years beginning after December 15, 1997, requires
that enterprises report a total for comprehensive income. Currently, the only
difference between "net income" and "comprehensive income" for K N is the
unrealized gain or loss on its investment in available-for-sale securities which
is recorded directly to stockholders' equity. For the quarters ended March 31,
1998 and 1997, the respective unrealized after-tax investment gain (loss) was
$1.8 million and $(1.4) million, resulting in comprehensive income of $24.3
million and $19.0 million, respectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

GENERAL

The following discussion should be read in conjunction with (i) the accompanying
interim Consolidated Financial Statements and related Notes and (ii) the
Consolidated Financial Statements, related Notes and Management's Discussion and
Analysis of Financial Condition and Results of Operations included in K N's 1997
Report on Form 10-K. Due to the seasonal variations in energy demand, among
other factors, the interim results which follow may not be indicative of the
results to be expected for an entire year. As discussed in Note 2 to the
accompanying interim Consolidated Financial Statements, the Company has engaged
in acquisition and divestiture transactions which affect the comparison of
results between periods.

Certain information contained herein may include forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. Although the Company believes that these
statements are based upon reasonable assumptions, it can give no assurance that
its goals will be achieved. Important factors that could cause actual results to
differ materially from those in the forward-looking statements contained herein
include, among other factors, the pace of deregulation of retail natural gas and
electricity markets in the United States, federal and state regulatory
developments, the timing and extent of changes in commodity prices for oil, gas,
NGLs, electricity, certain agricultural products and interest rates, the extent
of success in acquiring natural gas facilities, the timing and success of
efforts to develop power, pipeline and other projects, political developments in
foreign countries, and conditions of the capital markets and equity markets
during the periods covered by the forward-looking statements.


CONSOLIDATED FINANCIAL RESULTS

Consolidated net income for the first quarter of 1998 was $22.5 million, a $2.1
million (10.3%) increase from 1997 first-quarter net income of $20.4 million.
After deduction for preferred dividends, diluted earnings per share was $0.63
and $0.65 in the first quarter of 1998 and 1997, respectively, based on
respective weighted average common shares outstanding of 35.6 million and 31.2
million. The increased number of common shares outstanding in the first quarter
of 1998 was principally due to the early March 1998 public sale of $12.5 million
shares of common stock as described in Note 4 to the accompanying interim
Consolidated Financial Statements. Results for the first quarter of 1998
included (i) a pre-tax charge of approximately $4.4 million (approximately $2.7
million or $0.08 per diluted share after tax) due to costs attributable to the
acquisition and integration of MidCon, principally severance and relocation
costs associated with current or former K N employees and (ii) a pre-tax gain of
approximately $8.5 million (approximately $5.5 million or $0.15 per diluted
share after tax) from the sale of K N's Kansas natural gas distribution
properties (see Note 2 to the accompanying interim Consolidated Financial
Statements).

RESULTS OF OPERATIONS

Following is a discussion of (i) operating results by business segment, (ii)
"Other income (Deductions)" and (iii) "Income Taxes". In conjunction with the
adoption of Statement of Financial Accounting Standards No. 131, "Disclosure
About Segments of an Enterprise and Related Information", and reflecting the
Company's strategy of extracting margins from the various segments of the energy
value stream, the Company has segregated its results of operations into its
"Upstream", "Midstream" and "Downstream" components. The Company's Upstream
operations consist of (i) natural gas gathering, (ii) natural gas processing and
(iii) natural gas liquids

("NGLs") extraction and marketing activities; Midstream operations consist of
transportation, storage and bundled sales transactions for K N's interstate and
intrastate pipelines; Downstream activities consist of energy marketing and
regulated natural gas distribution. For comparative purposes, the Company's
previously reported results have been restated to conform to the current
presentation. Segment operating revenues, gas purchases, operations and
maintenance expenses and volumetric data given following are before intersegment
eliminations.

</TABLE>

Upstream operating income decreased from income of $8.3 million in the first
quarter of 1997 to a loss of $(8.3) million in the first quarter of 1998, a
decline of $16.6 million. Approximately $2.8 million (16.9%) of this unfavorable
variance was attributable to the first-quarter 1998 net results of Upstream
assets not owned or operated in the first quarter of 1997, including Bushton,
Interenergy and the gathering and processing assets of MidCon (see Note 2 to the
accompanying interim consolidated financial statements). The addition of these
assets was principally responsible for the increases in operating revenues,
operating expenses and volumes shown preceding, while the associated net
negative operating results were principally due to relatively low NGL prices as
discussed following which reduced margins from processing. With respect to the
$13.8 million negative variance associated with assets and operations included
in both quarters, approximately $8.7 million (63.0%) was attributable to a
decline in NGL prices from the first quarter of 1997 to the first quarter of
1998. Average NGL sales prices during these periods declined by approximately
$0.11 per gallon (26.8%). The remaining unfavorable variance was principally
attributable to reduced NGL recoveries at certain processing facilities 
and a refund of certain previously recorded gathering revenues.

Midstream operating income increased from $15.1 million in the first quarter of
1997 to $79.3 million in the first quarter of 1998, an increase of $64.2
million. This increase in operating income, as well as the significant increases
in operating revenues, operating expenses and volumes as shown preceding, was
principally attributable to the inclusion, in the first quarter of 1998, of two
months of operating results for the interstate and intrastate pipeline
operations of MidCon (see Note 2 to the accompanying interim Consolidated
Financial Statements) and a full quarter of results from the Pony Express
Pipeline, which was placed in service in the fourth quarter of 1997. These
incremental operations were responsible for approximately $71.1 million of
first-quarter 1998 operating income. The unfavorable variance of $6.9 million
associated with other operations in the Midstream segment was principally due to
a first-quarter 1998 decline in the profitability of certain Texas intrastate
pipeline operations due to a decline in sales volumes under certain contracts
resulting from (i) LDC unbundling and (ii) relatively warmer first-quarter 1998
weather. Additional unfavorable variance was attributable to the impact of
relatively warmer first-quarter 1998 weather on throughput and margins for the
remainder of K N's midstream operations.

</TABLE>

Downstream operating income decreased from $16.5 million in the first quarter of
1997 to $7.6 million in the first quarter of 1998, a decrease of $8.9 million
(53.9%), principally due to a decline of $6.7 million in operating income
attributable to limited sales of storage gas. Operating income for the first
quarter of 1998 also reflected a small positive contribution due to the addition
of the downstream activities of MidCon and Interenergy subsequent to their
acquisition (see Note 2 to the accompanying interim Consolidated Financial
Statements). In addition, the substantial increases in operating revenues,
operating expenses and volumes are largely due to the first-quarter 1998 impact
of these activities which were not a part of K N in the first quarter of 1997.
Activities included in both periods also experienced significant increases in
volume as well as associated operating revenues and expenses principally due to
intensified marketing efforts supported by an increased marketing staff. A small
decrease in the contribution from regulated retail activities reflected sales
volumes of approximately 6% below the first quarter of 1997, largely due to
warmer first-quarter 1998 weather.

</TABLE>

The increase of $42.6 million in interest expense from the first quarter of 1997
to the first quarter of 1998 is principally due to the incremental debt
associated with (i) the acquisition of MidCon effective January 30, 1998, (see
Note 2 to the accompanying interim Consolidated Financial Statements) and (ii)
the construction cost of the Pony Express Pipeline, which was placed in service
during the latter part of 1997. The increased first-quarter 1998 net expense
associated with "Minority Interests" was principally due to the dividend
requirement associated with the $100 million of Capital Trust Securities issued
in April 1997. The increase of $14.3 million in "Other, Net" from the first
quarter of 1997 to the first quarter of 1998 was principally due to (i) the
first-quarter 1998 gain of $8.5 million from K N's sale of its Kansas natural
gas distribution

properties, (ii) the increase of $2.6 million in interest income attributable to
earnings on the U.S. government securities held as collateral for the Substitute
Note issued in conjunction with the acquisition of MidCon and (iii) an increase
of $3.8 million in first-quarter 1998 income attributable to equity in the
earnings of unconsolidated subsidiaries (see Note 2 to the accompanying interim
Consolidated Financial Statements).

Of the $1.55 million increase in income tax expense from the first quarter of
1997 to the first quarter of 1998, approximately $1.35 million (87.2%) was
attributable to an increase in 1998 pre-tax income and the balance of
approximately $0.2 million (12.8%) was attributable to a minor increase in the
first-quarter 1998 effective tax rate.

LIQUIDITY AND CAPITAL RESOURCES

The following table illustrates the sources of the Company's invested capital
for the last three years and at March 31, 1998 and 1997. The balances at March
31, 1998 reflect the incremental capital associated with the acquisition of
MidCon, including the post-acquisition refinancings completed in the first
quarter of 1998. In addition, during April 1998, the Company issued $175 million
of Capital Trust Securities. For additional information on these financing
activities, see Note 4 to the accompanying interim Consolidated Financial
Statements.

The following discussion of cashflows should be read in conjunction with the
accompanying interim Consolidated Statement of Cash Flows and related
Supplemental Disclosures and with the Consolidated Statement of Cash Flows
included in the Company's 1997 Report on Form 10-K.

NET CASH FLOWS FROM OPERATING ACTIVITIES

"Net Cash Flows From Operating Activities" increased from approximately $43.3
million in the first quarter of 1997 to approximately $91.0 million in the
first quarter of 1998, an increase of approximately $47.7 million (110.2%).
This increase was principally attributable to (i) the increase in first-quarter
1998 earnings before non-cash charges and credits, largely due to the inclusion
of the results of operations of MidCon for two months (see Note 2 to the
accompanying interim Consolidated Financial Statements), (ii) the first-quarter
1998 receipt of $27.5 million in settlement of a gas contract and (iii) an
increase in first-quarter 1998 cash provided from miscellaneous working capital
items. These favorable variances were partially offset by cash used in the
first quarter of 1998 for miscellaneous non-working capital items.

NET CASH FLOWS FROM INVESTING ACTIVITIES

"Net Cash Flows Used in Investing Activities" increased from approximately
$154.3 million in the first quarter of 1997 to approximately $3.1 billion in
the first quarter of 1998, an increase of approximately $2.9 billion
principally due to (i) the $2.1 billion of net cash paid in the first quarter
of 1998 and (ii) the purchase of approximately $0.9 billion of U.S. government
securities to be held as collateral for the Substitute Note, in each case in
conjunction with the acquisition of MidCon (see Note 2 to the accompanying
interim Consolidated Financial Statements). Increased first-quarter 1998 cash
used for capital expenditures was largely offset by cash received from sales of
assets and reduced cash used for the purchase of investments.

NET CASH FLOWS FROM FINANCING ACTIVITIES

"Net Cash Flows From Financing Activities" increased from approximately $119.7
million in the first quarter of 1997 to approximately $3.0 billion in the first
quarter of 1998, an increase of approximately $2.9 billion. This increase
reflected the receipt of (i) approximately $2.36 billion in conjunction with the
public sale of debt securities and (ii) approximately $650 million in
conjunction with the public sale of common stock (in each case representing the
refinancing of acquisition debt associated with the purchase of MidCon), net of
associated issuance costs of approximately $45.9 million (see Notes 2 and 4 to
the accompanying interim Consolidated Financial Statements).

The Company's principal source of short-term liquidity is its bank facility
(see Note 8 (A) of Notes to Consolidated Financial Statements included in K N's
1997 Annual Report on Form 10-K) which makes available a total working capital
line of $1 billion. At March 31, 1998, the Company had borrowed $250 million
under this facility and had issued $135 million of commercial paper. The
Company believes its remaining capacity under this facility is adequate for its
expected short-term cash requirements.
