ITEM 1.  BUSINESS.

                                  INTRODUCTION

   Colorado is a Delaware corporation organized in 1927. All of Colorado's
outstanding common stock is owned by Coastal Natural Gas, which is a wholly-
owned subsidiary of Coastal. Colorado owns and operates an interstate natural
gas pipeline system and also has gas and oil exploration and production
operations. At December 31, 1994, the Company had 1,110 employees.

   The revenues and operating profit of the Company by industry segment for each
of the three years in the period ended December 31, 1994, and the related
identifiable assets as of December 31, 1994, 1993 and 1992, are set forth in
Note 12 of Notes to Consolidated Financial Statements included herein.



                               NATURAL GAS SYSTEM


OPERATIONS

GENERAL

   The Company is involved in the production, gathering, processing,
transportation, storage and sale of natural gas. Colorado purchases and produces
natural gas and makes sales of such gas at the wellhead principally to local gas
distribution companies for resale. Separately, Colorado contracts to gather,
process, transport and store natural gas owned by third parties.

   Colorado's gas transmission system extends from gas production areas in the
Texas Panhandle, western Oklahoma and western Kansas, northwesterly through
eastern Colorado to the Denver area, and from production areas in Montana,
Wyoming and Utah, southeasterly to the Denver area. The Company's gas gathering
and processing facilities are located throughout the production areas adjacent
to its transmission system. Most of the Company's gathering facilities connect
directly to its transmission system, but some gathering systems are connected to
other pipelines. The Company also has certain gathering facilities located in
New Mexico. Colorado owns four underground gas storage fields; three located in
Colorado, and one in Kansas.

   The Company's principal pipeline facilities at December 31, 1994 consisted of
6,356 miles of pipeline and 66 compressor stations with approximately 348,000
installed horsepower.  At December 31, 1994, the design peak day delivery
capacity of the transmission system was approximately 2.0 Bcf per day. The
underground storage facilities have a working capacity of approximately 29 Bcf
and a peak day delivery capacity of approximately 769 MMcf.

GAS SALES, STORAGE AND TRANSPORTATION

   Beginning in October 1993, Colorado implemented Order 636 on its system and
as a result, Colorado's gas sales contracts have been unbundled and such sales
are now made at the producer wellhead.  Colorado's gas sales contracts extend
through September 30, 1996, but provide for reduced customer purchases to be
made each year. Under Order 636, Colorado's certificate to sell gas for resale
allows sales to be made at negotiated prices and not at prices established by
the FERC. Colorado is also authorized to abandon all sales for resale at such
time as the contracts expire and without prior FERC approval. Effective October
1, 1993, Colorado formed an unincorporated Merchant Division to conduct most of
the Company's sales activity in the Order 636 environment. The gas sales volumes
reported include those sales which continue to be made by Colorado together with
those of its Merchant Division.

                                       1
<PAGE>
 
   Effective October 1, 1993, Colorado assigned an undivided interest in a
portion of its company-owned leases to a new subsidiary. The subsidiary
contracts to sell the production to Colorado's Merchant Division, which utilizes
the gas primarily for its sales to Colorado's traditional customers. The reserve
volumes reported represent those interests retained by Colorado together with
those assigned to the new subsidiary.

   Gas sales revenues were $139 million in 1994, compared to $223 million in
1993 and $261 million in 1992. The decreases are due largely to the fact that
prior to the mandated restructuring under Order 636, the costs of providing
gathering, storage and transportation services for sales customers were
recovered as part of the total resale rate and were classified as part of gas
sales revenue. Subsequent to restructuring, these costs are now recovered under
separate rates for each service.

   Colorado has engaged in "open access" transportation and storage of gas owned
by third parties for several years. In addition, prior to October 1, 1993,
Colorado provided storage and transportation services as part of its "bundled"
sales service. As a result of Order 636, the Company has "unbundled" these
services from its sales services and continues to provide these services to
third parties under individual contracts. Such services are at negotiated rates
that are within minimum and maximum levels approved by the FERC. Also, pursuant
to Order 636, the Company, on September 30, 1993, sold all of its working gas
except for 3.8 Bcf which it retained for operational needs.

   Colorado's deliveries for the years 1994, 1993 and 1992 are as follows:

     1992             428               1,169
</TABLE>

GAS GATHERING AND PROCESSING

   Colorado provides gathering and processing services on an "unbundled" or
stand-alone basis. The Company contracts for these services under terms which
are negotiated. With respect to gathering, the Company is limited to charging
rates which are between minimum and maximum levels approved by the FERC.
Processing terms are not subject to FERC approval, but Colorado is required to
provide "open access" to its processing facilities.

   Colorado has approximately 3,000 miles of gathering lines and approximately
110,200 horsepower of compression in its gathering operations. Colorado owns and
operates six gas processing plants which recovered approximately 88 million
gallons of liquid hydrocarbons in 1994, compared to 86 million gallons in 1993
and 77 million gallons in 1992, and 4,300 long tons of sulfur in 1994, compared
to 4,400 long tons in 1993 and 3,600 long tons in 1992. Additionally, in 1994,
Colorado processed approximately 6 million gallons of liquid hydrocarbons owned
by others compared to 12 million in 1993 and 10 million in 1992. These plants,
with a total operating capacity of approximately 697 MMcf daily, recover mainly
propane, butanes, natural gasoline, sulfur and other by-products, which are sold
to refineries, chemical plants and other customers.

COMPETITION

   Colorado has historically competed with interstate and intrastate pipeline
companies in the sale, transportation and storage of gas and with independent
producers, brokers, marketers and other pipelines in the gathering, processing
and sale of gas within its service areas. On October 1, 1993, the Company
implemented Order 636 on its system and as a consequence its gas sales contracts
have been unbundled at the producer wellhead. Order 636 also mandated
implementation of capacity release and secondary delivery point options allowing
a pipeline's firm transportation customers to compete with the pipeline for
interruptible transportation.  Additional information on Order 636 is included
under "Regulations Affecting Gas System" included herein.

                                       2
<PAGE>
 
   Natural gas competes with other forms of energy available to customers,
primarily on the basis of price. These competitive forms of energy include
electricity, coal, propane and fuel oils. Changes in the availability or price
of natural gas or other forms of energy, as well as changes in business
conditions, conservation, legislation or governmental regulations, capability to
convert to alternate fuels, changes in rate structure, taxes and other factors
may affect the demand for natural gas in the areas served by Colorado.


GAS SYSTEM RESERVES

GENERAL

   Colorado, through its unincorporated Merchant Division, continues to make
natural gas sales to a number of customers. In 1995, Colorado has sales contract
commitments of approximately 65,000 MMcf. Colorado will meet its sales
commitments primarily with purchases from third parties under existing contracts
and with production of Company-owned reserves. Colorado will also make monthly
spot gas purchases, if needed.

RESERVES

   The table below represents estimates of the Company's owned reserves as of
December 31, 1994, 1993, and 1992 (Bcf), as prepared by Huddleston, Colorado's
independent engineers.
<TABLE> 
<CAPTION> 

                                              1994     1993    1992

   Owned or controlled by Colorado..........   383     433     478
</TABLE> 


   The estimates of controlled gas reserves include quantities economically
recoverable over the productive life of existing wells and quantities estimated
to be recoverable in the future, either from completions in other productive
zones of existing wells or from additional wells to be drilled in proven
reservoirs currently controlled by Colorado. The independent engineers'
estimates of reserves are based upon new analyses or upon a review of earlier
analyses updated by production and field performance.

   At December 31, 1994, Colorado maintained under its own account 2 Bcf of
natural gas in underground working storage for system balancing. The Company has
an additional 38 Bcf of base gas in its four owned storage fields.

RESERVES DEDICATED TO A PARTICULAR CUSTOMER

   Colorado is committed to sell gas to Mesa Operating Company ("Mesa"), a
customer, under a 1928 agreement as amended, from specific owned gas reserves in
the West Panhandle Field of Texas. Under an amendment which became effective
January 1, 1991, a cumulative 23% of the total net production may be taken for
customers other than Mesa. Effective October 1, 1993, an undivided interest in
the West Panhandle Field leases, related to this 23% of the total net production
not committed to Mesa, was assigned by Colorado to a new subsidiary. The reserve
volumes reported represent those retained by Colorado as well as those assigned
to the new subsidiary.


REGULATIONS AFFECTING GAS SYSTEM

GENERAL

   Under the NGA, the FERC has jurisdiction over Colorado as to rates and
charges for the transportation and storage of natural gas and the construction
of new facilities, extension or abandonment of service and facilities, accounts
and records, depreciation and amortization policies and certain other matters.
In addition, the FERC has certificate authority over gas sales for resale in
interstate commerce, but under Order 636, had determined that it will not
regulate sales rates. Additionally, the FERC has asserted rate-regulation (but
not certificate regulation) over

                                       3
<PAGE>
 
gathering. Colorado is challenging the FERC's assertion of rate jurisdiction
over gathering, but has agreed in a settlement that for three years beginning
October 1, 1993, Colorado will post in its tariff the minimum and maximum
gathering rates which will be established and approved by the FERC. Colorado,
where required, holds certificates of public convenience and necessity issued by
the FERC covering its jurisdictional facilities, activities and services.

   Colorado is also subject to regulation with respect to safety requirements in
the design, construction, operation and maintenance of its interstate gas
transmission and storage facilities by the Department of Transportation.
Operations on United States government land are regulated by the Department of
the Interior.

   FERC Order Nos. 500 and 528 allowed regulated pipelines, including Colorado,
to recover, through a fixed charge, from 25% to 50% of the cost of payments made
to producers to extinguish outstanding claims under existing gas purchase
contracts or to secure reformation of existing contracts. Fixed charges are paid
by pipeline sales customers without regard to volumes of gas purchased. Under
this election, however, an amount equivalent to the amount included in the fixed
charge must be borne by the pipeline. Colorado has incurred costs related to
contract reformation and settlements of take-or-pay claims, a portion of which
has been recovered under Order Nos. 500 and 528.

   On April 8, 1992, the FERC issued Order 636 which required significant
changes in the services provided by interstate natural gas pipelines. The
Company and numerous other parties have sought judicial review of aspects of
Order 636. The case is currently in the briefing phase before the United States
Court of Appeals for the D.C. Circuit. Notwithstanding those appeals, the
Company has successfully complied with the requirements of Order 636.

   On July 2, 1993, the Company submitted to the FERC an unanimous offer of
settlement which resolved all the Order 636 restructuring issues which had been
raised in its restructuring proceedings. That settlement was ultimately approved
(except for minor issues), and the Company's restructured services became
effective October 1, 1993.   As of October 1, 1993, the Company separated all of
its services and separately contracts for each service on a stand-alone or
"unbundled" basis. Gathering, storage and transportation services are provided
at negotiated  rates established between minimum and maximum levels approved by
the FERC, while gas processing rates are not subject to FERC regulations.

RATE MATTERS

   Colorado's gas sales for resale contracts extend through September 30, 1996,
but provide for reduced customer purchases to be made each year. Under Order
636, Colorado's certificate to sell gas for resale allows sales to be made at
negotiated prices and not at prices established by the FERC. Colorado is also
authorized to abandon all sales for resale without prior FERC approval at such
time as the contracts expire. Pursuant to Order 636, Colorado's gas sales have
been unbundled at the producer wellhead. Effective October 1, 1993, Colorado
formed an unincorporated Merchant Division to conduct most of the Company's
sales activity in the Order 636 environment. The gas sales volumes reported
include those sales which continue to be made by Colorado together with those of
its Merchant Division.

   On March 31, 1993, Colorado filed at FERC under Docket RP93-99 to increase
its rates by approximately $26.5 million annually. Such rates (adjusted to
reflect Colorado's Order 636 program) became effective subject to refund on
October 1, 1993. On November 10, 1994, the FERC approved a settlement offer
submitted by the Company which resolved all of the issues in the proceeding. The
Company has implemented the rates established in the settlement for prospective
application and will be required to make refunds as a result of the approval of
the settlement. Such refunds will be distributed in March 1995. The Company has
fully accrued for these refunds and therefore such refunds will not have an
adverse effect on its consolidated financial position or results of operations.

   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. 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.

GAS AND OIL EXPLORATION AND PRODUCTION

   The Company has domestic gas and oil production operations. The gas is
delivered primarily to Colorado's interstate gas pipeline system while the crude
oil and condensate are sold at the wellhead to oil purchasing companies at
prevailing market prices. The production of gas and oil is subject to regulation
in states in which the Company operates.

   At December 31, 1994, the gas and oil properties of the Company included
leasehold interests covering 471,047 acres (353,978 net acres), of which 385,978
acres (320,852 net acres) were producing and 85,069 acres (33,126 net acres)
were undeveloped. The net producing acreage, held by production, is concentrated
principally in Texas (78%), Oklahoma (8%), Wyoming (6%) and Utah (6%). The net
undeveloped acreage, not held by production, is principally in Wyoming (45%),
Montana (22%) and Colorado (19%).

   The Company drilled 19 gross (7.68 net) gas wells, 22 gross (12.53 net) gas
wells, and 39 gross (34.41 net) gas wells in 1994, 1993 and 1992, respectively.

   Information on Company-owned reserves of oil and gas is included herein under
"Supplemental Information on Oil and Gas Producing Activities (Unaudited)" in
Item 14(a)1 included herein.



                                 ENVIRONMENTAL

   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. The Company anticipates annual capital
expenditures of $1 to $2 million  over the next several years aimed at
maintaining compliance with such laws and regulations. Additionally, appropriate
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", as reauthorized, imposes liability, without regard to
fault or the legality of the original act, for disposal of a "hazardous
substance." The Company is not presently, and has not been in the past, a
potentially responsible party

                                       5

("PRP") in any "Superfund" waste disposal sites.  However, the Company has
received notice from a committee formed from a group of 55 companies who are
named as PRPs at one site requesting the Company pay a de minimis share
(approximately $36,000) of the associated clean-up costs.

   There are additional areas of environmental remediation responsibilities
which may fall upon the Company. The states have regulatory programs that
mandate waste clean-up. The Clean Air Act Amendments of 1990 include new
permitting regulations which will result in increased operating expenditures.

   Future information and developments will require the Company to continually
reassess the expected impact of all applicable environmental laws and
regulations. Compliance with all applicable environmental protection laws  and
regulations is not expected to have a material adverse impact on the Company's
liquidity, consolidated financial position or results of operations.



                               OTHER DEVELOPMENTS

   In March 1994, the Company sold its interest in Natural Fuels Corporation to
CIC Stock Corporation, an affiliate.

ITEM 2.  PROPERTIES.

   Information on properties of Colorado is included in Item 1, "Business,"
included herein.

   The real property owned by the Company in fee consists principally of sites
for compressor and metering stations and microwave and terminal facilities. With
respect to the four owned storage fields, the Company holds title to gas storage
rights representing ownership of, or has long-term leases on, various subsurface
strata and surface rights and also holds certain additional mineral rights.
Under the NGA, the Company may acquire by the exercise of the right of eminent
domain, through proceedings in U.S. District Courts or in state courts,
necessary rights-of-way to construct, operate and maintain pipelines and
necessary land or other property for compressor and other stations and equipment
necessary to the operation of pipelines.

ITEM 3.  LEGAL PROCEEDINGS.

   In December 1992, certain of Colorado's natural gas lessors in the West
Panhandle Field filed a complaint in the U.S. District Court for the Northern
District of Texas, claiming underpayment, breach of fiduciary duty, fraud and
negligent misrepresentation. Management believes that Colorado has numerous
defenses to the lessors' claims, including (i) that the royalties were properly
paid, (ii) that the majority of the claims were released by written agreement,
and (iii) that the majority of the claims are barred by the statute of
limitations. Trial has been set for March 22, 1995.

   Other lawsuits and other proceedings which have arisen in the ordinary course
of business are pending or threatened against Colorado 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 of the above 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. Additional information regarding legal proceedings is set
forth in Notes 3 and 10 of Notes to Consolidated Financial Statements included
herein.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

(1)  Does not include the value of perquisites and other personal benefits
     because the aggregate amount of such compensation, if any, does not exceed
     the lesser of $50,000 or 10 percent of annual salary and bonus for any
     named individual.

(2)  Salary amounts for Messrs. Wyatt, Arledge and Cordes for 1992 and 1993
     include directors' fees paid during these periods which were previously
     reported under "All Other Compensation." Directors' fees for members of
     management of Coastal were eliminated in September, 1993. There was no
     salary change for Mr. Wyatt during 1994; the reduced base pay level for
     1994 was due to the September 1993 salary reduction (reported in the 1994
     Coastal Proxy Statement) being in effect for all of 1994.

(3)  Due to Coastal's practice of paying bi-weekly, there is one extra pay
     period reflected in the 1992 salary. Normally there are 26 pay periods, but
     approximately once every 11 years there are 27 pay periods; 1992 was such a
     year.

(4)  Although 1993 bonus awards were not finalized by Coastal's Compensation
     and Executive Development Committee until after the 1994 Coastal Proxy
     Statement had been prepared, all awards were based solely on 1993
     performance. Bonuses for 1992 were paid in equal installments over a three-
     year period, provided the employee was still employed on the anniversary
     date of the award. The 1994 bonuses were based on the following factors:
     the individual's position; the individual's responsibility and the
     individual's ability to impact Coastal's financial success.

(5)  The options do not carry any stock appreciation rights.

(6)  All Other Compensation for 1994 consists of:  (i) Coastal contributions to
     the Coastal Thrift Plan (O. S. Wyatt, Jr. $12,000; David A. Arledge
     $12,000; James F. Cordes $12,000; James A. King $4,232 and Sam F. Willson,
     Jr. $12,000) and (ii) certain payments in lieu of Thrift Plan contributions
     (O. S. Wyatt, Jr. $55,928; David A. Arledge $32,310; James F. Cordes
     $35,378; James A. King $2,645 and Sam F. Willson, Jr. $14,725). These
     payments are made to all employees of Coastal and its subsidiaries who
     participate in the Thrift Plan who must discontinue their Thrift Plan
     participation due to federal statutory limits.

   Mr. Cordes is employed pursuant to a five-year employment contract expiring

the employment contract, he will be entitled to receive for the remainder of the
term the salary, employee benefits, perquisites, salary increases, bonuses and
other incentive compensation which he would have received had he not been
terminated. Such reasons are a significant change in title, duties, authorities
or reporting responsibilities, a reduction in salary or benefits or a move of
the location of his office to a location not acceptable to him.

                COMPENSATION AND EXECUTIVE DEVELOPMENT COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION

   The following report has been provided by Coastal's Compensation and
Executive Development Committee (the "Committee") of the Board of Directors in
accordance with current Securities and Exchange Commission ("S.E.C.") proxy
statement disclosure requirements. The members of the Committee include John M.
Bissell (Chairman), Roy D. Chapin, Jr., and Jerome S. Katzin.

   This material states Coastal's current overall compensation philosophy and
program objectives. Detailed descriptions of Coastal's compensation programs are
provided as well as the information on Coastal's 1994 pay levels for the CEO.

OVERALL OBJECTIVES OF THE EXECUTIVE COMPENSATION PROGRAM

   Coastal's compensation philosophy and program objectives are directed by two
primary guiding principles. First, the program is intended to provide fully
competitive levels of compensation - at expected levels of performance - in
order to attract, motivate and retain talented executives. Second, the program
is intended to create an alignment of interests between Coastal's executives and
shareowners such that a significant portion of each executive's compensation is
directly linked to maximizing shareholder value.

   In support of this philosophy, the executive compensation program is designed
to reward performance that is directly relevant to Coastal's short-term and
long-term success. As such, Coastal attempts to provide both short-term and
long-term incentive pay that varies based on corporate and individual
performance.

   To accomplish these objectives, the Committee has structured the executive
compensation program with three primary underlying components: base salary,
annual incentives, and long-term incentives (i.e., stock options). The following
sections describe Coastal's plans by element of compensation and discuss how
each component relates to Coastal's overall compensation philosophy.

   In reviewing this information, reference is often made to the use of
competitive market data as criteria for establishing targeted compensation
levels. Coastal targets the market 50th percentile for its total compensation
program and actual total compensation rates are generally consistent with that
target. (However, Coastal's competitive pay posture varies by pay element, as
described below.) Several market data sources are used by Coastal, including
energy industry norms for the publicly traded peer companies included in
Coastal's shareholder return performance graphs, as reflected in these
companies' proxy statements. In addition, we utilize published survey data and
data obtained from independent consultants that are for general industry
companies similar in size (i.e., revenues) to Coastal. The published surveys
include data on over 40 companies of comparable size to  Coastal, as measured by
revenues. Greater emphasis is placed on the published data and data obtained
from consultants than on the data for proxy peers, since the published data and
consulting data are reflective of company size.

BASE SALARY PROGRAM

   Coastal's base salary program is based on a philosophy of providing base pay
levels that fall between the market 50th and 75th percentiles. Coastal
periodically reviews its executive pay levels to assure consistency with the
external market. Generally, Coastal's actual base salary levels for 1994 for
executives as a group were consistent with the targeted percentiles. We believe
it is crucial to provide strongly competitive salaries over time in order to
attract and retain executives who are highly talented.

                                       13
<PAGE>
 
   Annual salary adjustments for Coastal are based on several factors: general
levels of market salary increases, individual performance, competitive base
salary levels, and Coastal's overall financial results. Coastal reviews
performance qualitatively considering total shareholder returns, the level of
earnings, return on equity, return on total capital and individual business unit
performance. These criteria are assessed qualitatively and are not weighted. All
base salary increases are based on a philosophy of pay-for-performance and
perceptions of an individual's long-term value to Coastal. As a result,
employees with higher levels of performance sustained over time will be paid
correspondingly higher salaries.

THE ANNUAL BONUS PLAN

   Coastal's Annual Bonus Plan is intended to (1) reward key employees based on
company/business unit and individual performance; (2) motivate key employees;
and (3) provide competitive cash compensation opportunities to plan
participants. Under the plan, target award opportunities vary by individual
position and are expressed as a percent of base salary. The individual target
award opportunities, which are slightly below market median levels, are then
aggregated into a total target pool which is adjusted as described below. The
amount a particular executive may earn is directly dependent on the individual's
position, responsibility, and ability to impact Coastal's financial success.

   The actual bonus pool is established each year by modifying the target pool
based on Coastal's overall performance against measures established by the
Committee. In fiscal year 1994, the key performance measure considered was
earnings before interest and taxes ("EBIT") against plan. This measure was
weighted 50% of the total bonus program. In 1994 Coastal's EBIT performance
significantly improved over 1993 performance. This 1994 EBIT achievement was
above threshold standards (minimum performance level for bonus payment) but
below a very aggressive plan, resulting in the EBIT portion of the bonus paid
being below target. The remaining 50% of the annual bonus opportunity in 1994 is
a discretionary annual bonus pool. As a result, no formula performance measures
were used in establishing the size of awards under this portion of the plan.
However, in establishing the size of the discretionary bonus pool, the Committee
considered Coastal's Return on Equity relative to industry peers (using the same
peers included in the shareholder return graphs), Return on Total Capital
compared to industry peers, the EBIT performance of each business unit, progress
made toward improving Coastal's operational and financial performance, and the
need to reward unique individual contributions. These measures were not formally
weighted by the Committee. The size of the discretionary bonus pool element was
established above threshold but below target based on the qualitative
performance assessment described above. As a result, actual bonus payments for
1994 were below target and median market levels.

   Individual awards from the established bonus pool are recommended by senior
management, with advice and consent from the Committee. Individual awards from
the pool are based on business unit and individual employee performance, future
potential, and competitive considerations. All individual performance
assessments are conducted in a non-formula fashion without specific goal
weightings. The total bonus awards made may not exceed the amount of funds in
the bonus pool.

LONG-TERM INCENTIVE PLAN

   Coastal's Long-Term Incentive Plan ("LTIP") is designed to focus executive
efforts on the long-term goals of Coastal and to maximize total return to
Coastal's shareholders. While Coastal's LTIP allows the Committee to use a
variety of long-term incentive devices, the Committee has relied solely on stock
option awards to provide long-term incentive opportunities in recent years.

   Stock options align the interests of employees and shareholders by providing
value to the executive through stock price appreciation only. All stock options
have a ten year term before expiration and are fully exercisable within 7 years
of the grant date.

   No stock options were granted to the Named Executive Officers in 1994 since
Coastal made larger than normal grants to key executives in December 1993.
However, it is anticipated that stock option awards will be made periodically at
the discretion of the Committee in the future. As in past years, the number of
shares actually granted

                                       14
<PAGE>
 
to a particular participant is also based on Coastal's financial success, its
future business plans, and the individual's position and level of responsibility
within Coastal. All of these factors are assessed subjectively and are not
weighted.

1994 CHIEF EXECUTIVE OFFICER PAY

   As previously described, the Committee considers several factors in
developing an executive's compensation package. For the CEO, these include
competitive market practices (consistent with the philosophy described for other
executives), experience, achievement of strategic goals, and the financial
success of Coastal (considering the factors described under the annual bonus
plan above).

   Mr. Wyatt received no salary increase in 1994. The Committee took no action
regarding Mr. Wyatt's base salary, in spite of significantly improved Coastal
performance during the year. This lack of any adjustment is not a reflection of
performance; rather, it is based on considering strong input from the CEO, who
wants to see continued improvement in shareholder returns before receiving any
base salary increase.

   Mr. Wyatt's bonus for 1994 performance was $200,000. This bonus award was
below targeted levels (and below market median levels) since Coastal's aggregate
performance on the measures described in the annual bonus section of this report
was below the aggressive Coastal targets (but above 1993 levels).

   The Committee granted no stock options to Mr. Wyatt in 1994 (consistent with
past practices), considering the strongly expressed opinion of the CEO. Mr.
Wyatt and the Committee considered Mr. Wyatt's current level of stock ownership
in reaching this decision.

$1 MILLION PAY DEDUCTIBILITY CAP

   Under Section 162(m) of the Internal Revenue Code, public companies are
precluded from receiving a tax deduction on compensation paid to executive
officers in excess of $1 million. To address the $1 million pay deductibility
cap issue, Coastal's 1994 LTIP was structured so that stock option awards (which
are intended to be the primary long-term incentive vehicle for the present time)
qualify for an exemption from the $1 million pay deductibility limit.

   Also, at the present time, the CEO is the only executive whose base salary
plus target bonus exceeds $1 million. In order to preserve Coastal's tax
deduction for the CEO's base salary plus bonus, Coastal has established a
nonqualified deferred compensation program for Mr. Wyatt. Under this program,
any annual incentive awards that  bring Mr. Wyatt's cash compensation to a level
over $1 million will be deferred so that payments occur after Mr. Wyatt is no
longer a Named Executive Officer, thus preserving the deductibility of the pay
for Coastal.

(A) Compensation covered under the Pension Plan for employees of Coastal and the
    Coastal Replacement Pension Plan generally includes only base salary and is
    limited to $150,000 for 1994.

(B) Federal legislation has reduced the benefit which may be earned due to
    future service; however, benefits previously earned may not be reduced. At
    December 31, 1994 each of the individuals named in the Summary Compensation
    Table had covered salary for future benefit accrual of $150,000 and the
    following years of credited service and pension payable at age 65 (or
    current age, if over 65): Mr. Wyatt, 39 years, $469,834; Mr. Arledge, 14
    years, $54,181; Mr. Cordes, 17 years, $74,523; Mr. King, 2 years, $9,474
    (not vested) and Mr. Willson, 22 years, $98,357.

(C) The normal form of retirement income is a straight life annuity. Benefits
    payable under the Pension Plan are subject to offset by 1.5% of applicable
    monthly social security benefits multiplied by the number of years of
    credited service (up to 33 years).

   The Employee Retirement Income Security Act of 1974, as amended by subsequent
legislation, limits the retirement benefits payable under the tax-qualified
Pension Plan. Where this occurs, Coastal will provide to certain executives,
including persons named in the Summary Compensation Table, additional
nonqualified retirement benefits under a Coastal Replacement Pension Plan. These
benefits, plus payments under the Pension Plan, will not exceed the maximum
amount which Coastal would have been required to provide under the Pension Plan
before application of the legislative limitations, and are reflected in the
above table and footnote (B).

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


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

                        LIQUIDITY AND CAPITAL RESOURCES

   The Company uses the following consolidated ratios to measure liquidity and
ability to meet future funding needs and debt service requirements.
<TABLE>

                                                                            1994   1993    1992

<S>                                                                        <C>     <C>    <C>
   Cash flow from operating activities to capital expenditures and debt
   service requirements..................................................  374.5%  80.0%  105.2%
 
   Debt to total capitalization..........................................   30.3%  33.3%   27.1%
 
   Times interest earned (before tax)....................................    7.4    6.5     7.2
</TABLE>

   The Company's primary needs for cash are capital expenditures and debt
service requirements. Capital expenditures, debt retirements and other cash
needs in each of the years 1992 through 1994 and the sources of capital used to
finance these expenditures are summarized in the Statement of Consolidated Cash
Flows. Management believes the Company's stable financial position and earnings
ability will enable it to continue to generate and obtain capital for financing
needs in the foreseeable future.

   Cash flow from operating activities amounted to $195.7 million in 1994 and
$77.6 million in 1993. Pre-payments for gas supply and settlement of natural gas
contract disputes required investments of $28 thousand in 1994 and $7.1 million
in 1993. Liquidity needs were met in 1994 by internally generated funds.

   The Company has adopted a capital expenditure budget of approximately $71.3
million for 1995, an increase from the capital additions of $52.3 million in
1994. The anticipated increase in 1995 is the result of a $24.6 million increase
for natural gas projects partially offset by a $5.6 million decrease for
exploration and production projects. Alternatives to finance capital
expenditures and other cash needs are primarily limited by the terms of a
Coastal Natural Gas debt instrument. As of December 31, 1994, the Company and
certain affiliates could incur approximately $770 million of additional
indebtedness. For the Company and such affiliates to incur indebtedness for
borrowed money in excess of this amount, approximately $350 million of
indebtedness under this agreement would need to be retired.

   The Company participates in a program which matches short-term cash excesses
and requirements of participating affiliates, thus minimizing borrowings from
outside sources. At December 31, 1994, the Company had advanced $220.7 million
to associated companies at a market rate of interest. Such amount is repayable
on demand.

   The Company is responding to the extensive changes in the natural gas
industry by continuing to take steps to operate its facilities at their maximum
efficient capacity, renegotiating the remaining gas purchase contracts which are
above market in an effort to lower its cost of gas and reduce take-or-pay
obligations, pursuing innovative marketing strategies and applying strict cost-
cutting measures.

   The Company adopted FAS No. 112, "Employers' Accounting for Postemployment
Benefits", effective January 1, 1994. This standard covers the accounting for
estimated costs of benefits provided to former or inactive employees before
their retirement. The effect of this new standard did not have a material effect
on the Company's consolidated financial position or results of operations.

   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. The Company anticipates annual capital
expenditures of $1 to $2 million over the next several years aimed at
maintaining compliance with such laws and regulations. Additionally, appropriate
governmental authorities may enforce the laws and regulations with a variety of
civil and criminal enforcement measures, including monetary penalties and
remediation requirements.

                                      F-1
<PAGE>
 
   The Comprehensive Environmental Response, Compensation and Liability Act,
also known as "Superfund", as reauthorized, imposes liability, without regard to
fault or the legality of the original act, for disposal of a "hazardous
substance." The Company is not presently, and has not been in the past, a
potentially responsible party ("PRP") in any "Superfund" waste disposal sites.
However, the Company has received notice from a committee formed from a group of
55 companies who are named as PRPs at one site requesting the Company pay a de
minimis share (approximately $36,000) of the associated clean-up costs.

   There are additional areas of environmental remediation responsibilities
which may fall upon the Company. The states have regulatory programs that
mandate waste clean-up. The Clean Air Act Amendments of 1990 include new
permitting regulations which will result in increased operating expenditures.

   Future information and developments will require the Company to continually
reassess the expected impact of all applicable environmental laws and
regulations. Compliance with all applicable environmental protection laws and
regulations is not expected to have a material adverse impact on the Company's
liquidity, consolidated financial position or results of operations.

NATURAL GAS

   On April 8, 1992, the FERC issued Order 636 which required significant
changes in the services provided by interstate natural gas pipelines (see Note
10 of the Notes to Consolidated Financial Statements). The Company's
restructured services became effective October 1, 1993, and the Company now
offers a wide range of "unbundled" storage, transportation and balancing
services. Colorado's gas sales contracts have been unbundled and such sales are
now made at the producer wellhead. Gas sales contracts extend through September
30, 1996, but provide for reduced customer purchases to be made each year.

   1994 Versus 1993. Revenues from natural gas operations decreased in 1994 due
to lower average sales prices of $59 million, the $35 million sale of storage
gas inventory in 1993 pursuant to the implementation of Order 636, an $11
million decrease resulting from reduced sales volumes, increased reservations of
$17 million and reduced extracted products revenue of $4 million offset by
increased transportation and gathering revenues of $55 million and increased
contract storage revenue of $7 million.

   1993 Versus 1992. Revenues from natural gas operations increased in 1993 due
to the $35 million sale of storage gas inventory, increased transportation and
gathering revenues of $34 million and increased extracted products revenue of $4
million offset by lower sales prices of $23 million and a $15 million decrease
resulting from reduced sales volumes.

   The daily average volumes of natural gas sold were 259 MMcf, 272 MMcf and 287
MMcf for 1994, 1993 and 1992, respectively. However, over the remaining life of
Colorado's current gas sales contracts (most of which extend through September
30, 1996), it is expected that customers will reduce their contractual sales
entitlement pursuant to the provisions of Order 636. At this time, however, the
magnitude of those conversions cannot be estimated with reasonable certainty.
Transportation volumes increased by 9% in 1994 over the 1993 level and are
expected to increase slightly in 1995.

                                      F-2
<PAGE>
 
EXPLORATION AND PRODUCTION

   1994 Versus 1993. Revenues from exploration and production increased in 1994
as natural gas volumes generated a $9 million increase and other increases of $2
million were partially offset by decreased natural gas sales prices of $5
million.

   1993 Versus 1992. Revenues from exploration and production increased in 1993
as natural gas volumes generated a $4 million increase and natural gas prices
increased by $1 million, partially offset by decreases of $1 million.

OTHER INCOME - NET

   The increase in 1994 and the decrease in 1993 primarily reflect changes in
interest income resulting from loans to affiliated companies.

COST OF GAS SOLD

   1994 Versus 1993.  The decrease is due primarily to reduced average gas
purchase rates of $24 million, reduced purchase volumes of $9 million, decreased
gas used costs of $19 million, decreased transportation, gathering and exchange
gas costs of $15 million and storage gas costs associated with the 1993 sale of
storage gas inventory pursuant to Order 636, net of injection/withdrawals in the
amount of $11 million, partially offset by other increases of $3 million.

   1993 Versus 1992. The increase in 1993 was due primarily to increased
transportation, gathering and exchange gas costs of $17 million and storage gas
costs associated with the sale of storage gas inventory pursuant to Order 636,
net of injection/withdrawals in the amount of $11 million, partially offset by
other decreases of $1 million.

OPERATION AND MAINTENANCE

   1994 Versus 1993. Operation and maintenance expenses increased in 1994 due
primarily to increased gas used in operations of $19 million partially offset by
decreased gas and gas liquids handling of $3 million, decreased production taxes
of $3 million and other decreases of $2 million.

   1993 Versus 1992. Operation and maintenance expenses increased in 1993 due
primarily to increased property and production taxes of $3 million, increased
professional services of $2 million, increased gas used costs of $2 million and
other increases of $1 million.

DEPRECIATION, DEPLETION AND AMORTIZATION

   1994 Versus 1993.  Depreciation, depletion and amortization increased $5
million in 1994 due primarily to increased production volumes in the exploration
and production segment and an increase in the natural gas segment's depreciable
plant.

   1993 Versus 1992. Depreciation, depletion and amortization increased $8
million in 1993 due primarily to an increase in the natural gas segment's
depreciable plant and increased production volumes in the exploration and
production segment.

OPERATING PROFIT

   The following table reflects the increase (decrease) in operating profit
experienced by segment during the past two years (millions of dollars):

NATURAL GAS

   1994 Versus 1993. The natural gas segment's operating profit increase in 1994
is due to decreased gas related costs of $75 million and an increase in other
income of $5 million partially offset by decreased operating revenues of $64
million and increased operation and maintenance expenses of $11 million.

   1993 Versus 1992. The natural gas segment's operating profit decrease in 1993
is due to increased gas related costs of $27 million, increased operation and
maintenance expenses of $6 million, increased depreciation, depletion and
amortization expenses of $6 million and other increases of $3 million partially
offset by increased operating revenues of $35 million.

EXPLORATION AND PRODUCTION

   1994 Versus 1993. The exploration and production segment's operating profit
increase in 1994 is due to increased revenues of $6 million, partially offset by
a $4 million increase in depreciation, depletion and amortization.

   1993 Versus 1992. The exploration and production segment's operating profit
was unchanged from 1992 as increased revenues of $4 million were offset by
increases of $2 million for operation and maintenance expenses and $2 million
for depreciation, depletion and amortization.

INTEREST EXPENSE

   The decrease in both 1994 and 1993 is primarily due to lower average debt
outstanding partially offset by increases in other financial expenses.

TAXES ON INCOME

   Income taxes fluctuated primarily as a result of changing levels of income
before taxes and changes in the effective income tax rate. The effective federal
income tax rate for the Company was 33% in 1994 and 32% in 1993 and 1992.

Board of Directors and Stockholders
Colorado Interstate Gas Company
Colorado Springs, Colorado


   We have audited the accompanying consolidated balance sheets of Colorado
Interstate Gas Company (an indirect wholly-owned subsidiary of The Coastal
Corporation) and subsidiaries as of December 31, 1994 and 1993, and the related
consolidated statements of earnings, retained earnings and additional paid-in
capital and cash flows for each of the three years in the period ended December
31, 1994. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

   In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Colorado Interstate Gas Company and
subsidiaries as of December 31, 1994 and 1993, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1994 in conformity with generally accepted accounting principles.

   As discussed in Note 8 to the consolidated financial statements, in 1993 the
Company changed its method of accounting for postretirement benefits other than
pensions to conform with Statement of Financial Accounting Standards No. 106.

                COLORADO INTERSTATE GAS COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. Summary of Significant Accounting Policies

- -  Basis of Presentation

   Colorado is a subsidiary of Coastal Natural Gas, a wholly-owned subsidiary of
Coastal. The stock of the Company was contributed by Coastal to Coastal Natural
Gas effective April 30, 1982. The financial statements presented herewith are
presented on the basis of historical cost and do not reflect the basis of cost
to Coastal Natural Gas.

   The Company is regulated by and subject to the regulations and accounting
procedures of the FERC. Colorado meets the criteria and, accordingly, follows
the reporting and accounting requirements of FAS No. 71, "Accounting for the
Effects of Certain Types of Regulation."

- -  Principles of Consolidation

   The Consolidated Financial Statements include the accounts of the Company and
its subsidiaries after eliminating all significant intercompany transactions.

- -  Statement of Cash Flows

   For purposes of this Statement, cash equivalents include time deposits,
certificates of deposit and all highly liquid instruments with original
maturities of three months or less. The Company made cash payments for interest,
net of amounts capitalized, of $17.5 million, $20.3 million and $20.7 million in
1994, 1993 and 1992, respectively. Cash payments for income taxes amounted to
$41.9 million, $40.5 million and $22.5 million in 1994, 1993 and 1992,
respectively.

- -  Inventories

   Materials and supplies inventories are carried principally at average cost.
Gas stored underground is carried at last-in, first-out cost ("LIFO"). The
excess of replacement cost over the carrying value of gas in underground storage
carried by the LIFO method, which is classified as Plant, Property and
Equipment, was $31.2 million and $52.6 million at December 31, 1994 and 1993,
respectively.

- -  Plant, Property and Equipment

   Property additions and betterments are capitalized at cost. In accordance
with accounting requirements of the FERC, an allowance for equity and borrowed
funds used during construction is included in the cost of the natural gas
segment's additions and betterments. This cost amounted to $1.9 million, $1.2
million and $2.4 million in 1994, 1993 and 1992, respectively. All costs
incurred in the acquisition, exploration and development of gas and oil
properties, including unproductive wells, are capitalized under the full-cost
method of accounting.

   The Company generally provides for depreciation on a straight-line basis,
although the unit-of-production method is used for depreciation, depletion and
amortization of certain natural gas properties. The depreciation rates for
production and gathering, products extraction, storage, and transmission plant
are 1.55 percent, 3.85 percent, 2.90 percent, and 2.60 percent, respectively.
The unit-of-production method is utilized for depreciation, depletion and
amortization of oil and gas properties. The average amortization rate per
equivalent unit of a thousand cubic feet of gas production for oil and gas
properties was $0.96 for the year 1994 and $1.00 for the years 1993 and 1992.

   The cost of minor property units replaced or retired, net of salvage, is
credited to plant accounts and charged to accumulated depreciation, depletion
and amortization. Since provisions for depreciation, depletion and amortization
expense are made on a composite basis, no adjustments to accumulated
depreciation, depletion and amortization are made in connection with retirements
or other dispositions occurring in the ordinary course of business. Gain or loss
on sales of major property units is credited or charged to income.

- -  Income Taxes

   The Company follows the liability method of accounting for deferred federal
income taxes as required by the provisions of FAS No. 109, "Accounting for
Income Taxes." The Company is a member of a consolidated group which files a
consolidated federal income tax return. Members of the consolidated group with
taxable income are charged with the amount of income taxes as if they filed
separate federal income tax returns, and members providing deductions and
credits which result in income tax savings are allocated credits for such
savings.

- -  Gain or Loss on Reacquired Debt

   As required by the FERC, gain or loss on reacquired debt is deferred and
amortized over the remaining life of the related long-term indebtedness.

- -  Revenue Recognition

   The Company recognizes revenues for the sale of their products in the period
of delivery. Revenue for services are recognized in the period the services are
provided.

- -  Reclassification of Prior Period Statements

   Certain minor 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 results of operations or
financial position.

2. Long-Term Debt

   Balances at December 31 were as follows (thousands of dollars):

   10% Senior Debentures, due 2005...................  $179,225    $179,145
                                                       ========    ========
</TABLE> 

   The 10% Senior Debentures, due 2005, are not redeemable prior to maturity and
have no sinking fund provisions.

   Alternatives to finance capital expenditures and other cash needs are
primarily limited by the terms of a Coastal Natural Gas debt instrument. As of
December 31, 1994, the Company and certain affiliates could incur approximately
$770 million of additional indebtedness. For the Company and such affiliates to
incur indebtedness for borrowed money in excess of this amount, approximately
$350 million of indebtedness under this agreement would need to be retired.

3. Take-or-Pay Obligations

   The Consolidated Balance Sheet includes assets of $5.7 million and $13.2
million at December 31, 1994 and 1993, respectively, relating to prepayments for
gas under gas purchase contracts with producers and settlement payment amounts
relative to the restructuring of gas purchase contracts as negotiated with
producers. As a result of the implementation of Order 636 by the Company on
October 1, 1993 (see Note 10 of Notes to Consolidated Financial Statements), gas
sales are made at negotiated prices and are not subject to regulatory price
controls. This does not affect the recoverability or the results of pending
take-or-pay litigation or any take-or-pay or contractual reformation settlements
that the Company may achieve with respect to periods before October 1, 1993. A
portion of the costs associated with take-or-pay incurred prior to October 1,
1993, may continue to be recovered pursuant to FERC's Order No. 528.

   A few gas producers have instituted litigation arising out of take-or-pay
claims against the Company. In the Company's experience, producers' claims are
generally vastly overstated and do not consider all adjustments provided for in
the contract or allowed by law. The Company has resolved the majority of the
exposure with its suppliers for approximately 11% of the amounts claimed. At
December 31, 1994, the Company estimated that unresolved asserted and unasserted
producers' claims amounted to approximately $18.0 million. The remaining
disputes will be settled where possible and litigated if settlement is not
possible.

                                      F-11
<PAGE>
 
   At December 31, 1994, the Company was committed to make future purchases
under certain take-or-pay contracts with fixed, minimum or escalating price
provisions. Based on contracts in effect at that date, and before considering
reductions provided in the contracts or applicable law, such commitments are
estimated to be $.8 million, $.7 million, $.7 million, $.6 million and $.6
million for the years 1995-1999, respectively, and $2.9 million thereafter. Such
commitments have not been adjusted for all amounts which may be assigned or
released, or for the results of future litigation or negotiation with producers.

   The Company has made provisions, which it believes are adequate, for payments
to producers that may be required for settlement of take-or-pay claims and
restructuring of future contractual commitments. In determining the net loss
relating to such provisions, the Company has also made accruals for the
estimated portion of such payments which would be recoverable pursuant to FERC-
approved settlements with customers. Such provisions and accruals were not
material to the Company for the years 1994, 1993 and 1992.

4. Common Stock and Other Stockholders' Equity

   All of the Company's common stock is owned by Coastal Natural Gas.

   Certain provisions of the preferred stock resolutions restrict the payment of
dividends on common stock; however, all $364.8 million of retained earnings were
available for dividends on the common stock of the Company at December 31, 1994.

5. Mandatory Redemption Preferred Stock

   The Company's Mandatory Redemption Preferred Stock consists of the following:

   5.50% Cumulative Preferred Stock (Third Series) - Of the 150,000 shares
authorized and issued, 5,560 were outstanding as of December 31, 1994. The
remaining stock outstanding is due in 1997 at par value with an annual dividend
rate of 5.5%.

   The outstanding series of the Company's Mandatory Redemption Preferred Stock
is a $100 par value, cumulative, non-convertible and non-voting issue. If at any
time dividends on the Mandatory Redemption Preferred Stock shall be in arrears
in an amount equal to six quarterly dividends, holders of the Mandatory
Redemption Preferred Stock, voting as a class, will have the right to elect not
less than one-fourth of the Company's Board of Directors until all accrued and
unpaid dividends on the Mandatory Redemption Preferred Stock are paid in full.
In addition, if at any time dividends shall be in arrears in an aggregate amount
equal to eight full quarterly dividends, holders of these securities, voting as
a class, will have the right to elect such number of Directors as shall be
necessary to constitute a minimum majority of the Board of Directors until all
accrued and unpaid dividends on the Mandatory Redemption Preferred Stock are
paid in full.

6. Fair Value of Financial Instruments

   The estimated fair value amounts of the Company's financial instruments have
been determined by the Company, using appropriate market information and
valuation methodologies. Considerable judgment is required to develop the
estimates of fair value, thus, the estimates provided herein are not necessarily
indicative of the amounts that could be realized in a current market exchange.

   The carrying values of cash and the notes receivable from affiliates are
reasonable estimates of their fair values. The estimated value of the Company's
long-term debt and mandatory redemption preferred stock is based on interest
rates at December 31, 1994 and 1993, respectively, for new issues with similar
remaining maturities.

   Coastal and the Internal Revenue Service ("IRS") Appeals Office have settled
all contested adjustments to federal income tax returns filed for the years 1982
through 1984. Coastal's federal income tax returns filed for the years 1985
through 1987 have been examined by the IRS, and Coastal has received notice of
proposed adjustments to the returns for each of those years. Coastal currently
is contesting certain of these adjustments with the IRS Appeals Office.
Examinations of Coastal's federal income tax returns for 1988, 1989 and 1990 are
currently in progress. It is the opinion of management that adequate provisions
for federal income taxes have been reflected in the Company's consolidated
financial statements.

   Provisions for federal income taxes were different from the amount computed
by applying the statutory U.S. federal income tax rate to earnings before tax.
The reasons for these differences are (thousands of dollars):

8. Benefit Plans

   The Company participates in the non-contributory pension plan of Coastal (the
"Plan") which covers substantially all employees. The Plan provides benefits
based on final average monthly compensation and years of service. As of December
31, 1994, the Plan did not have an unfunded accumulated benefit obligation.
Colorado made no contributions to the Plan for 1994, 1993 or 1992. Assets of the
Plan are not segregated or restricted by participating subsidiaries and pension
obligations for Company employees would remain the obligation of the Plan if the
Company were to withdraw.

   The Company also makes contributions to a thrift plan, which is a trusteed,
voluntary and contributory plan for eligible employees of the Company. The
Company's contributions, which are based on matching employee contributions,
amounted to approximately $2.8 million for each of the years 1994 and 1993 and
$2.6 million for 1992.

   The Company provides certain health care and life insurance benefits for
retired employees. Effective January 1, 1993, the Company adopted FAS No. 106,
"Employers' Accounting for Postretirement Benefits Other Than Pensions" ("FAS
No. 106"). FAS No. 106 requires the Company to accrue the estimated cost of
retiree benefit payments during the years the employee provides services. The
Company previously expensed the cost of these benefits, which are principally
health care, as claims were incurred. FAS No. 106 allows recognition of the
cumulative effect of the liability in the year of the adoption or the
amortization of the obligation over a period of up to twenty years. The Company
elected to recognize the initial postretirement benefit obligation of
approximately $18.2 million over a period of twenty years. Recognition of FAS
No. 106 cost is determined by currently effective rates as filed with the FERC.
The difference between actuarially determined FAS No. 106 costs and the level of
costs collected in rates is reflected as a deferred regulatory amount.

Net postretirement benefit cost consisted of the following components:
 
 Service cost - benefits earned during the period..............................  $   .3   $   .2
 Interest cost on accumulated postretirement benefit obligation................     1.2      1.5

 Net postretirement benefit cost...............................................  $  3.2   $   .8

</TABLE>

   The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation was 12.0% in 1994, declining gradually to 6.0%
by the year 2005. The assumed health care cost trend rate used in measuring the
accumulated postretirement benefit obligation was 16.0% in 1993. A one
percentage point increase in the assumed health care cost trend rate for each
year would increase the accumulated postretirement benefit obligation as of
December 31, 1994 and the net postretirement health care cost by approximately
4.01%. The assumed discount rate used in determining the accumulated
postretirement benefit obligation was 8.75%.

   The Company adopted FAS No. 112, "Employers' Accounting for Postemployment
Benefits" effective January 1, 1994. This standard covers the accounting for
estimated costs of benefits provided to former or inactive employees before
their retirement. The implementation of the new standard did not have a material
effect on the Company's consolidated financial position or results of
operations.

9. Commitments

   The Company and its subsidiaries had rental expense of approximately $7.3
million, $9.0 million and $9.7 million in 1994, 1993 and 1992, respectively
(excluding leases covering natural resources). The aggregate minimum lease
payments under existing noncapitalized long-term leases are estimated to be $4.5
million, $3.6 million,  $1.7 million, $1.6 million, and $.9 million for the
years 1995-1999, respectively, and $1.1 million thereafter.

   The Company has executed a service agreement with WIC, an affiliate,
providing for the availability of pipeline transportation capacity through
January 1, 2004. Under the service agreement, the Company is required to make
minimum payments on a monthly basis. The estimated amounts of minimum annual
payments are as follows (thousands of dollars):

                   Later years..   14,700

   The Company expensed approximately $4.6 million related to the minimum
payments under this agreement in 1994.

10.  Litigation and Regulatory Matters

- -  Litigation

   In December 1992, certain of Colorado's natural gas lessors in the West
Panhandle Field filed a complaint in the U.S. District Court for the Northern
District of Texas, claiming underpayment, breach of fiduciary duty, fraud and
negligent misrepresentation. Management believes that Colorado has numerous
defenses to the lessors' claims, including (i) that the royalties were properly
paid, (ii) that the majority of the claims were released by written agreement,
and (iii) that the majority of the claims are barred by the statute of
limitations. Trial has been set for March 22, 1995.

   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 of the above 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.

- -  Rate Matters

   Colorado's gas sales for resale contracts extend through September 30, 1996,
but provide for reduced customer purchases to be made each year. Under Order
636, Colorado's certificate to sell gas for resale allows sales to be made at
negotiated prices and not at prices established by the FERC. Colorado is also
authorized to abandon all sales for resale without prior FERC approval at such
time as the contracts expire. Pursuant to Order 636, Colorado's gas sales have
been unbundled at the producer wellhead. Effective October 1, 1993, Colorado
formed an unincorporated Merchant Division to conduct most of the Company's
sales activity in the Order 636 environment. The gas sales volumes reported
include those sales which continue to be made by Colorado together with those of
its Merchant Division.

   On March 31, 1993, Colorado filed at FERC under Docket RP93-99 to increase
its rates by approximately $26.5 million annually. Such rates (adjusted to
reflect Colorado's Order 636 program) became effective subject to refund on
October 1, 1993. On November 10, 1994, the FERC approved a settlement offer
submitted by the Company which resolved all of the issues in the proceeding. The
Company has implemented the rates established in the settlement for prospective
application and will be required to make refunds as a result of the approval of
the settlement. Such refunds will be distributed in March 1995. The Company has
fully accrued for these refunds and therefore such refunds will not have an
adverse effect on its consolidated financial position or results of operations.

   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. 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.

12.  Segment Reporting

   Natural gas system operations and gas and oil exploration and production are
the two segments of the Company's operations.

   Natural gas system operations involve the production, purchase, gathering,
storage, transportation and sale of natural gas, principally to and for public
utilities, industrial customers, other pipelines, and other gas customers, as
well as the operation of natural gas liquids extraction plants.

   Gas and oil exploration and production operations involve primarily the
development and production of natural gas, crude oil, condensate and natural gas
liquids.

   Operating revenues by segment include both sales to unaffiliated customers,
as reported in the Company's statement of consolidated earnings, and
intersegment sales, which are accounted for on the basis of contract, current
market, or internally established transfer prices. The intersegment sales are
from the exploration and production segment to the natural gas segment.

   Operating profit is total revenues less interest income from affiliates and
operating expenses. Operating expenses exclude income taxes, corporate general
and administrative expenses and interest.

   Identifiable assets by segment are those assets that are used in the
Company's operations in each segment.

   Services provided by the Company at cost for affiliated companies were $8.3
million for 1994, $7.9 million for 1993 and $8.1 million for 1992. Services
provided by affiliated companies for the Company at cost were $7.7 million for
1994, $8.1 million for 1993 and $7.9 million for 1992. The services provided by
the Company to affiliates, and by affiliates to the Company, primarily reflect
the allocation of costs relating to the sharing/operating of facilities and
general and administrative functions. Such costs are allocated using a three
factor formula consisting of revenue, property and payroll, or other methods
which have been applied on a reasonable and consistent basis.

   In 1989, the Company entered into two separate five-year lease agreements
with ANR Western Storage Company, an affiliate, for the rental of certain
pipeline facilities. Rental expense of approximately $1.4 million for 1994, $1.5
million in 1993 and $1.6 million in 1992 was recorded in conjunction with the
terms of the lease agreements.

   In 1992, the Company entered into a five-year lease agreement with ANR
Production Company, an affiliate, for the rental of certain pipeline facilities.
Annual rental expense of approximately $.2 million was recorded in 1994, 1993
and 1992 in conjunction with the terms of the lease agreement.

   The Company participates in a program which matches short-term cash excesses
and requirements of participating affiliates, thus minimizing total borrowings
from outside sources. At December 31, 1994, the Company had advanced $220.7
million to associated companies at a market rate of interest. Such amount is
repayable on demand.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
 AND GAS RESERVE QUANTITIES

   Future cash inflows from the sale of proved reserves and estimated production
and development costs, as calculated by the Company's independent engineers, are
discounted at 10% after they are reduced by the Company's estimate for future
income taxes. The calculations are based on year-end prices and costs, statutory
tax rates and nonconventional fuel source tax credits that relate to existing
proved oil and gas reserves in which the Company has mineral interests.

   The standardized measure is not intended to represent the market value of
reserves and, in view of the uncertainties involved in the reserve estimation
process, including the instability of energy markets, may be subject to future
revisions (thousands of dollars):
