Item 1. Financial Statements.

     The financial statements of ANR Pipeline Company and its subsidiaries (the
"Company" or "ANR Pipeline") are presented herein and are unaudited, except for
balances as of December 31, 1999, and therefore are subject to year-end
adjustments; however, all adjustments which are, in the opinion of management,
necessary for a fair statement of the results of operations for the periods
covered have been made. The adjustments which have been made are of a normal
recurring nature. Such results are not necessarily indicative of results to be
expected for the year due to seasonal variations and market conditions affecting
natural gas deliveries.

                      ANR PIPELINE COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   Summary of Significant Accounting Policies

     For additional information relative to operations and financial position,
reference is made to the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 1999. Certain reclassifications of prior period
statements have been made to conform with current reporting practices. The
effect of the reclassifications was not material to the Company's consolidated
financial position, results of operations or cash flows.

     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("FAS 133"), as amended by Statement of Financial Accounting
Standards No. 137, to be effective for all fiscal quarters of fiscal years
beginning after June 15, 2000. FAS 133 requires that an entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The accounting for changes
in the fair value of a derivative will depend on the intended use of the
derivative and the resulting designation. The Company is currently evaluating
the impact, if any, of FAS 133.

     The Company may periodically enter into futures contracts to hedge the
price risk of natural gas anticipated to be sold to end users. The Company
defers the impact of changes in the market value of these contracts until such
time as the hedged transaction is completed. At that time, the impact of the
changes in the fair market value of these contracts is recognized in income.

     Supplemental information relative to the Statement of Consolidated Cash
Flows includes the following: The Company made cash payments for interest, net
of interest capitalized, of $5.8 million and $5.5 million for the three-month
periods ended March 31, 2000 and 1999, respectively. Cash payments for income
taxes amounted to $13.4 million and $18.9 million for the three-month periods
ended March 31, 2000 and 1999, respectively.

2.   Income Taxes

     Provisions for income taxes were as follows (millions of dollars):

3.   Common Stock

     All of the issued and outstanding common stock of the Company is owned by
American Natural Resources Company, a wholly owned subsidiary of Coastal Natural
Gas Company. Coastal Natural Gas Company is a wholly owned subsidiary of The
Coastal Corporation ("Coastal"). Therefore, earnings and cash dividends per
common share have no significance and are not presented.

4.   Litigation, Environmental and Regulatory Matters

     Litigation Matters

     In October 1996, Coastal, along with certain of its affiliates, including
ANR Pipeline, was named as a defendant in a suit filed by several former and
current African American employees in the U.S. District Court, Southern District
of Texas (the "Texas suit"). The Texas suit alleges racially discriminatory
employment policies and practices. Coastal and its affiliates vigorously deny
these allegations and have filed responsive pleadings. Plaintiffs' counsel are
seeking to have the Texas suit certified as a class action of all former and
current African American employees and initially claimed compensatory and
punitive damages of $400 million. In February 1999, in response to Coastal's
motion to deny class certification, plaintiffs' counsel obtained permission from
the Court to delete all claims for compensatory and punitive damages and to seek
equitable relief only.

     In January 1998, the plaintiffs in the Texas suit amended their suit to
exclude ANR Pipeline employees from the potential class. A new suit was then
filed in state court in Wayne County, Michigan, seeking to have the Michigan
suit certified as a class action of African American employees of ANR Pipeline
and seeking unspecified damages as well as attorneys and expert fees. The
Company has filed responsive pleadings denying these allegations. In August
1999, the court denied plaintiffs' motion to have the Michigan suit certified as
a class action. Plaintiffs filed with the Michigan Court of Appeals an
application for leave to appeal the denial of the class certification. On
November 5, 1999, the Michigan Court of Appeals denied the application for leave
to appeal.

     Two legal proceedings, one in federal court and the other in state court,
have been instituted against a number of gas pipeline companies and their
affiliates, including ANR Pipeline, Coastal and several of Coastal's other
subsidiaries. The plaintiffs in each suit seek damages for the alleged
undermeasurement of the heating value and the volume of natural gas. In the
federal proceeding, Jack Grynberg filed 77 separate False Claim Act suits in
September 1997 against natural gas transmission companies and producers,
gatherers, and processors of natural gas, seeking unspecified damages which
could include treble damages for the maximum period permitted by law
(potentially as much as ten years) and penalties of up to $10,000 per false
claim. In addition to the measurement claims, these suits also allege that the
defendants undervalued the gas in paying royalties. The Coastal defendants were
sued in the U.S. District Courts of Colorado and the Eastern District of
Michigan. In April 1999, the U.S. Department of Justice notified the Company
that the United States would not intervene in these cases at that time. The
MultiDistrict Litigation Panel has consolidated the Grynberg suits with several
other Grynberg cases for pre-trial proceedings in Wyoming. The defendants filed
a motion to dismiss which was argued in March 2000, and the parties are awaiting
the Court's decision.

     In the state proceedings, the Quinque Operating Company, on behalf of
itself and subclasses of gas producers, royalty owners, overriding royalty
owners, and state taxing authorities, in May 1999 instituted a legal proceeding
in State Court in Stevens County, Kansas against over 200 gas companies,
including ANR Pipeline and several other Coastal subsidiaries. The Quinque suit
seeks unspecified actual, punitive and treble damages for the alleged
undermeasurement of all natural gas measured in the United States from
non-federal and non-Indian lands since 1974. The plaintiffs are seeking
certification of a national class of all similarly situated gas producers,
royalty owners, overriding royalty owners, and state taxing authorities. The
suit was removed to the U.S. District Court for the District of Kansas. The
plaintiffs filed a motion to remand the case back to the state court. The
MultiDistrict Litigation Panel has transferred the Quinque suit to Wyoming and
consolidated it with the Grynberg proceedings as a result of a motion filed by
several of the defendants in the Quinque suit.

     Numerous other lawsuits and other proceedings which have arisen in the
ordinary course of business are pending or threatened against the Company or its
subsidiaries. Although no assurances can be given and no determination can be
made at this time as to the outcome of any particular lawsuit or proceeding, the
Company believes there are meritorious defenses to substantially all such claims
and that any liability which may finally be determined should not have a
material adverse effect on the Company's consolidated financial position or
results of operations.

     Environmental Matters

     The Company's operations are subject to extensive and evolving federal,
state and local environmental laws and regulations which may affect such
operations and costs as a result of their effect on the construction, operation
and maintenance of its pipeline facilities. Compliance with such laws and
regulations can be costly. Additionally, governmental authorities may enforce
the laws and regulations with a variety of civil and criminal enforcement
measures, including monetary penalties and remediation requirements.

     The Comprehensive Environmental Response, Compensation and Liability Act,
also known as "Superfund," imposes liability for the release of a "hazardous
substance" into the environment. Superfund liability is imposed without regard
to fault and even if the waste disposal was in compliance with the then current
laws and regulations. With the joint and several liability imposed under
Superfund, a potentially responsible party ("PRP") may be required to pay more
than its proportional share of such costs. The Company has been named as a PRP
in three Superfund waste disposal sites. At these sites, there is sufficient
information to estimate total cleanup costs of approximately $52 million and the
Company estimates its pro-rata exposure, to be paid over a period of several
years, is approximately $1.3 million and has made appropriate provisions.

     In Michigan, where the Company has extensive operations, the Environmental
Response Act requires individuals (including corporations) who have caused
contamination to remediate the contamination to regulatory standards. Owners or
operators of contaminated property who did not cause the contamination are not
required to remediate the contamination, but must exercise due care in their use
of the property so that the contamination is not exacerbated and the property
does not pose a threat to human health. ANR Pipeline estimates that its costs to
comply with the Michigan regulations will be approximately $6.2 million, which
will be expended over a period of several years and for which appropriate
provisions have been made.

     In October 1998, the U. S. Environmental Protection Agency ("EPA")
announced a "Finding of Significant Contribution and Rulemaking for Certain
States in the Ozone Transport Assessment Group Region for Purposes of Reducing
Regional Transport of Ozone" ("NOx SIP Call"). The NOx SIP Call requires 22
states, including eight states in which ANR Pipeline operates, and the District
of Columbia to submit state implementation plans ("SIP Plans"), with each state
showing how it intends to reduce NOx emissions from sources located within its
borders to specified levels. Under the schedule proposed by the EPA in the NOx
SIP Call, states had until September 1999 to submit SIP Plans to the EPA, and
reduction measures would have to be in place by May 1, 2003. The NOx SIP Call
provided that if a state failed to submit compliant SIP Plans by the September
1999 deadline, the EPA would impose reductions upon specific sources within the
state. The NOx SIP Call is the subject of legal proceedings instituted by nine
of the affected states and numerous affected industries. In a May 1999 order,
the U. S. District Court, District of Columbia stayed, until further order of
the court, the date by which states must submit compliant SIP Plans. ANR
Pipeline operates compressor engines that emit nitrogen oxide and is, therefore,
potentially subject to any state or EPA rules issued under the NOx SIP Call.
Until the legal proceedings referenced above are resolved, final rules are
determined and the states have submitted compliant SIP Plans, the Company will
not be able to reasonably estimate the amount of any obligation resulting from
the NOx SIP Call.

     Future information and developments, including legislative and enforcement
developments, will require the Company to continually reassess the expected
impact of these environmental matters. However, the Company has evaluated its
total environmental exposure based on currently available data, including its
potential joint and several liability, and believes that compliance with all
applicable laws and regulations will not have a material adverse impact on the
Company's consolidated financial position or results of operations.

     Regulatory Matters

     On July 29, 1998, the Federal Energy Regulatory Commission ("FERC") issued
a "Notice of Proposed Rulemaking," in which the FERC has proposed a number of
significant changes to the industry, including, among other things, removal of
price caps in the short-term market (less than one year), capacity auctions,
changed reporting obligations, the ability to negotiate terms and conditions of
all services, elimination of the requirement of a matching


                                      - 7 -

<PAGE>

term cap on the renewal of existing contracts and a review of its policies for
approving capacity construction. On the same day, the FERC also issued a "Notice
of Inquiry" soliciting industry input on various matters affecting the pricing
of long-term service and certificate pricing in light of changing market
conditions. On February 9, 2000, the FERC issued a final rule implementing
certain of the changes that were discussed in these two proposals. Among other
things, the final rule: (a) removes the price ceilings for short-term secondary
market capacity releases for a trial period through September 30, 2002; (b)
permits pipelines to propose seasonally and term-differentiated rates; (c)
revises requirements relating to pipeline scheduling procedures, capacity
segmentation and penalties; (d) narrows the right-of-first-refusal granted to
long-term shippers to retain their capacity; and (e) expands pipeline reporting
requirements. ANR Pipeline, its affiliates and others have sought clarification
of certain aspects of the final rule.

     On September 15, 1999, the FERC issued a Policy Statement addressing the
certification and pricing of new pipeline construction projects. Under the
Policy Statement, applicants must first satisfy a threshold pricing requirement
of demonstrating that their projects can be constructed without subsidies from
existing customers. Second, the applicants must show that any adverse impacts of
the project on identified interests (existing customers of the applicant, other
existing pipelines and their captive customers, landowners and the surrounding
communities) are outweighed by its benefits, i.e., a balancing of adverse
impacts and benefits. On October 19, 1999, ANR Pipeline and its affiliates
sought clarification and/or rehearing of the Policy Statement insofar as it does
not apply directly to those projects filed for approval under the FERC's
"optional certificate" regulations. Other parties also sought rehearing of this
and other aspects of the Policy Statement. On February 9, 2000, the FERC issued
an order which, among other things, held that the Policy Statement balancing
criteria would apply to new optional certificate applications while it receives
comments on a companion FERC notice proposing to eliminate the current optional
certificate regulations.

     Certain regulatory issues remain unresolved among the Company, its
customers, its suppliers and the FERC. The Company has made provisions which
represent management's assessment of the ultimate resolution of these issues. As
a result, the Company anticipates that these regulatory matters will not have a
material adverse effect on its consolidated financial position or results of
operations. While the Company estimates the provisions to be adequate to cover
potential adverse rulings on these and other issues, it cannot estimate when
each of these issues will be resolved.

5.   Merger

     Coastal and El Paso Energy Corporation ("El Paso Energy") announced on
January 18, 2000 the execution of definitive agreements for the merger of
Coastal and El Paso Energy. On May 5, 2000, the merger was approved by the
shareholders of Coastal and El Paso Energy. Each share of Coastal common stock
and Class A common stock will be converted on a tax-free basis (except for cash
paid in lieu of fractional shares) into 1.23 shares of El Paso Energy common
stock. The outstanding convertible preferred stock of Coastal will be exchanged
tax free (except for cash paid in lieu of fractional shares) for El Paso Energy
common stock on the same basis as if the preferred stock had been converted into
Coastal common stock immediately prior to the merger. It is expected that the
merger will be completed during the fourth quarter of 2000 and be accounted for
as a pooling of interests. The merger is subject to various conditions,
particularly federal regulatory approval.

Item 2.    Management's Discussion and Analysis of Financial Condition and
           Results of Operations.

     This report includes certain forward-looking statements. The
forward-looking statements reflect the Company's expectations, objectives and
goals with respect to future events and financial performance and are based on
assumptions and estimates which the Company believes are reasonable. However,
actual results could differ materially from anticipated results. Important
factors which may affect the actual results include, but are not limited to,
commodity prices, political developments, market and economic conditions,
industry competition, the weather, changes in financial markets and changing
legislation and regulations. The forward-looking statements contained in this
Report are intended to qualify for the safe harbor provisions of Section 21E of
the Securities Exchange Act of 1934, as amended.

     The Notes to Consolidated Financial Statements contain information that is
pertinent to the following analysis.

     The information required by this Item is presented in a reduced disclosure
format pursuant to General Instruction (H) of Form 10-Q.

                              Results of Operations

     The change in the Company's earnings for the three-month period ended March
31, 2000 in comparison to the corresponding period in 1999 is a result of the
following:

     Revenues. Other revenues decreased by $8.3 million for the three-month
period ending March 31, 2000 as compared to the same period in 1999. The
decrease was primarily due to the gain on the sale of certain assets in 1999 of
$8.1 million.

     Operation and Maintenance. Operation and maintenance expenses increased by
$18.6 million for the three-month period ending March 31, 2000 as compared to
the same period in 1999. The increase is primarily the result of a $15 million
benefit recorded in the first quarter of 1999, related to revisions of certain
gas costs, gas transportation costs and environmental cleanup cost accruals. The
remainder is largely due to higher use tax expenses resulting primarily from
favorable settlements for prior years in certain states recognized in the first
quarter of 1999.

     Taxes on Income. Taxes on income decreased by $9.6 million for the
three-month period ending March 31, 2000 as compared to the same period in 1999
primarily due to lower pre-tax income.
