                                     PART I

ITEMS 1 AND 2 .   BUSINESS AND PROPERTIES

BUSINESS ENVIRONMENT

      Northwest Pipeline Corporation ("Pipeline") is wholly owned by The
Williams Companies, Inc. ("Williams").

      Pipeline owns and operates an interstate natural gas pipeline system,
including facilities for mainline transmission and gas storage.  Pipeline's
transmission and storage activities are subject to regulation by the Federal
Energy Regulatory Commission ("FERC") under the Natural Gas Act of 1938
("Natural Gas Act") and under the Natural Gas Policy Act of 1978 ("NGPA"), and,
as such, its rates and charges for the transportation of natural gas in
interstate commerce, the extension, enlargement or abandonment of its
jurisdictional facilities, and its accounting, among other things, are subject
to regulation.

      Pipeline has significant future opportunities to provide service to meet
the demands of growing gas markets.  Pipeline's geographical position allows
access to the incremental sources of supply required for these markets.

TRANSMISSION

      Pipeline owns and operates a pipeline system for the mainline
transmission of natural gas.  This system extends from the San Juan Basin in
northwestern New Mexico and southwestern Colorado through Colorado, Utah,
Wyoming, Idaho, Oregon and Washington to a point on the Canadian border near
Sumas, Washington.  At December 31, 1994, Pipeline's system, having an
aggregate mainline deliverability of almost 2.5 Bcf* of gas per day, was
composed of approximately 3,900 miles of mainline and branch transmission
pipelines, and 43 mainline compressor stations with a combined capacity of
approximately 291,000 horsepower.

      Pipeline operates under an open-access transportation certificate wherein
gas is transported for third party shippers.  Pipeline's transportation
services represented 100% of its total throughput in 1994, reflecting the
implementation of FERC's Order No. 636 during 1993.





- --------------------
*     The term "Mcf" means thousand cubic feet, "MMcf" means million cubic feet
and "Bcf" means billion cubic feet.  All volumes of natural gas are stated at a
pressure base of 14.73 pounds per square inch absolute at 60 degrees
Fahrenheit.  The term "MMBtu" means one million British Thermal Units and
"TBtu" means one trillion British Thermal Units.





                                     -1-
<PAGE>   4
      In 1994, Pipeline transported natural gas for a total of 101 customers.
Pipeline provides services for markets in California, New Mexico, Colorado,
Utah, Nevada, Wyoming, Idaho, Oregon and Washington. Transportation customers
include distribution companies, municipalities, interstate and intrastate
pipelines, gas marketers and direct industrial users.  The three largest
transportation customers of Pipeline in 1994 accounted for approximately 14.4%,
11.4% and 10.3%, respectively, of total transportation volumes.  No other
customer accounted  for  more than  10% of  total  volumes moved on  Pipeline's
mainline system.  Pipeline's firm transportation agreements are generally
long-term agreements with various expiration dates and account for the major
portion of Pipeline's business.  Additionally, Pipeline offers interruptible
transportation service under agreements that are generally short term.

      No other interstate natural gas pipeline company presently provides
significant service to Pipeline's primary gas consumer market area.  However,
competition with other interstate carriers exists for expansion markets.
Competition also exists with alternate fuels.  Electricity and distillate fuel
oil are the primary alternate energy sources in the residential and commercial
markets.  In the industrial markets, high sulfur residual fuel oil is the main
alternate fuel source.

      Pipeline believes that strong economies in the Pacific Northwest and the
growing preference for natural gas in response to environmental concerns
support future expansions of its mainline capacity.  In August 1993, Pipeline
filed applications for FERC approval to build additional mainline expansions
totaling 360 MMcf of gas per day of system capacity.  In order to assure
unneeded capacity was not constructed, in March 1994 Pipeline allowed expansion
shippers to reduce their contracted level of service.  As a result, Pipeline
filed an amended certificate reducing the expansions to 164 MMcf of gas per day
of increased system capacity at an estimated cost of $99.5 million to be in
service by the end of 1995.  Most of the expansion shippers reducing their
contracted level of service were able to obtain needed service through readily
available firm segmented capacity releases under FERC Order No. 636 which
Pipeline implemented on November 1, 1993.  Other opportunities include the
construction of $15 million of lateral and meter station expansions to meet
existing customers' shifting demand patterns under FERC Order No. 636.

GAS STORAGE

      Underground gas storage facilities enable Pipeline to balance daily
receipts and deliveries and provide storage services to certain major
customers.

      Pipeline has a contract with a third party, under which gas storage
services are provided to Pipeline in an underground storage reservoir in the
Clay Basin Field located in Daggett County, Utah.  Pipeline injects its own gas
into the storage reservoir  and is authorized to utilize the Clay Basin Field
at a seasonal storage level of 6.1 Bcf of working gas, with a firm delivery
capability of 51 MMcf of gas per day.

      Pipeline owns a one-third interest in the Jackson Prairie underground
storage facility located near Chehalis, Washington, with the remaining
interests owned by two of Pipeline's distribution customers.  The authorized
seasonal storage capacity of the facility is 15.1 Bcf of working gas.  The
facility provides peak day deliveries to Pipeline of up to 450 MMcf per day on
a firm basis and up to an additional 72 MMcf per day on a best-efforts basis.
Certain of Pipeline's major customers own the working gas stored at the
facility.

      Pipeline also owns and operates a liquefied natural gas ("LNG") storage
facility located near Plymouth, Washington, which provides standby service for
Pipeline's customers during extreme peaks in demand.  The facility has a total
LNG storage capacity equivalent to 2.4 Bcf of gas, liquefaction capability of
12 MMcf per day and regasification capability of 300 MMcf per day.  Certain of
Pipeline's major customers own the gas stored at the LNG plant.

CONTRACT REFORMATION AND GAS SUPPLY CONTRACT ISSUES

      Pursuant to FERC policy, Pipeline filed to recover a portion of contract
reformation costs through direct bills to former sales customers and through
surcharges to transportation as well as sales commodity rates.  The total
amount of contract reformation costs authorized by FERC to be collected by
Pipeline by means of a direct bill mechanism was $34 million.  All amounts have
been recovered at December 31, 1994.

      FERC initially approved Pipeline's use of a mechanism to direct bill
Pipeline's contract reformation costs, but when challenged on appeal, sought a
remand to reassess its order concerning the billing mechanism.  Pipeline has
received an order from FERC that requires Pipeline to reallocate such contract
reformation costs using a different method.  Although reallocation will require
refunds of certain amounts, it is expected that Pipeline will be permitted to
recover substantially all of these costs from other customers.

      In 1989, the FERC issued an order to Pipeline instituting a formal
investigation related to the assignment by Pipeline of certain gas supply
contracts to an affiliate.  Pipeline was ordered to show cause why the
assignments did not violate certain federal statutes and FERC regulations.  By
order dated October 5, 1992, the FERC set the matter for an expedited hearing
before an Administrative Law Judge ("ALJ").  The ALJ issued a decision in favor
of Pipeline on May 13, 1993.  On April 6, 1994, the FERC issued an order
terminating all proceedings and affirming the ALJ's May 13, 1993 decision in
favor of Pipeline.

OTHER REGULATORY MATTERS

      Pipeline's transportation of natural gas in interstate commerce is
subject to regulation by FERC under the Natural Gas Act or the NGPA.  Pipeline
holds certificates of public convenience and necessity issued by FERC
authorizing it to own and operate all pipelines, facilities and properties
considered jurisdictional for which certificates are required under the Natural
Gas Act.

      Pipeline is subject to the Natural Gas Pipeline Safety Act of 1968, as
amended by Title I of the Pipeline Safety Act of 1979, which regulates safety
requirements in the design, construction, operation and maintenance of
interstate gas transmission facilities.

      On April 1, 1993, Pipeline began collecting new rates, subject to refund,
under the provisions of its rate case filed October 1, 1992.  On July 28, 1994,
Pipeline received an initial decision from an ALJ on this rate case.  This
decision will be considered by the FERC prior to its issuance of a final order.
Pipeline has raised exceptions with the FERC to the ALJ decision and is
awaiting the FERC's final order.  Pipeline believes the outcome of the final
order is not likely to have a significant effect on net income.

      On November 1, 1994, Pipeline began collecting new rates, subject to
refund, under the provisions of its rate case filed April 29, 1994.  This new
filing seeks a revenue increase for a projected deficiency caused by increased
costs and loss of cost recovery assigned to a transportation contract
terminated subsequent to the rate case filed on October 1, 1992.

OWNERSHIP OF PROPERTY

      Pipeline's system is owned in fee.  However, a substantial portion of
Pipeline's system is constructed and maintained pursuant to rights-of-way,
easements, permits, licenses or consents on and across properties owned by
others.  The compressor stations of Pipeline, with appurtenant facilities, are
located in whole or in part upon lands owned by Pipeline and upon sites held
under leases or permits issued or approved by public authorities.  The LNG
plant is located on lands owned in fee by Pipeline.  Pipeline's debt indentures
restrict the sale or disposal of a major portion of its pipeline system.

EMPLOYEES

      At December 31, 1994, Pipeline employed 540 persons, none of whom are
represented under collective bargaining agreements.  No strike or work stoppage
in any of Pipeline's operations has occurred in the past and relations with
employees are good.

ENVIRONMENTAL MATTERS

      Pipeline is subject to the National Environmental Policy Act and other
federal and state legislation regulating the environmental aspects of its
business.  Management believes that Pipeline is in substantial compliance with
existing environmental requirements.  Pipeline believes that, with respect to
any capital expenditures required to meet applicable standards and regulations,
FERC would grant the requisite rate relief so that, for the most part, such
expenditures and a return thereon would be permitted to be recovered.  Pipeline
believes that compliance with applicable environmental requirements is not
likely to have a material effect upon Pipeline's earnings or competitive
position.  Refer to Note 1 of Notes to Financial Statements for a summary of
accounting policy on environmental matters.

ITEM 3.  LEGAL PROCEEDINGS

      Various suits and claims, including those referred to in Note 10 of Notes
to Financial Statements and above under "Contract Reformation and Gas Supply
Contract Issues" and "Other Regulatory Matters", arising in the ordinary course
of business, are pending against Pipeline.  While the ultimate effect of such
actions cannot be ascertained at this time, in the opinion of management of
Pipeline and its counsel, the possible liabilities (after consideration of
amounts accrued, insurance coverage or other indemnification arrangements)
which may result from such actions are not likely to have a materially adverse
financial effect upon Pipeline in the future.

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

      Since Pipeline meets the conditions set forth in General Instruction
(J)(1)(a) and (b) of Form 10-K, this information is omitted.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
           MATTERS

      Pipeline is wholly owned by Williams.

      The payment of dividends by Pipeline on its common stock is restricted
under various debt agreements.  Under the most restrictive provisions, the
amount of Pipeline's retained earnings available for dividends on its common
stock as of December 31, 1994, was approximately $150.5 million.  In 1994 and
1993, Pipeline paid cash dividends on common stock of $30 million and $18
million, respectively.

ITEM 6.  SELECTED FINANCIAL DATA

      Since Pipeline meets the conditions set forth in General Instruction
(J)(1)(a) and (b) of Form 10-K, this information is omitted.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

      This analysis discusses financial results of Pipeline's operations for
the years 1992 through 1994.

RESULTS OF OPERATIONS

Year Ended December 31, 1994 vs. Year Ended December 31, 1993

      Operating revenues decreased $38.1 million, or 14% due primarily to the
absence of natural gas sales and completion of contract reformation surcharge
billings early in 1994, partially offset by expanded firm transportation
service.  Natural gas sales were eliminated following the implementation,
during the fourth quarter of 1993, of FERC Order No. 636 which converted
remaining sales customers to firm transportation service.

      Operating expenses decreased $44.5 million, or 25%, primarily due to the
absence of gas purchase volumes as a result of implementation of FERC Order No.
636, the completion of contract reformation and lower maintenance expenses,
partially offset by higher operation expenses, depreciation and amortization,
and taxes other than income taxes.

      Operating income increased $6.5 million, or 7%, primarily due to higher
revenues from expanded firm transportation service and lower maintenance
expenses partially offset by higher operation expenses, depreciation and
amortization, and taxes other than income taxes.

      Other income decreased $6.9 million, or 86%, primarily due to a decrease
in the allowance for equity funds used during construction associated with
Pipeline's mainline expansion completed and placed into service April 1, 1993,
a decrease in interest income from short-term investing and a reserve related
to rate issues.

      Interest on long-term debt decreased $1.8 million as the result of
retiring certain sinking fund debt obligations in 1994.  Other interest expense
decreased $1.8 million primarily due to the absence of deferred carrying
charges on contract reformation costs.

Year Ended December 31, 1993 vs. Year Ended December 31, 1992

      Operating revenues increased $25.1 million, or 10%, due primarily to
increased firm transportation service and higher average transportation rates,
partially offset by lower natural gas sales volumes arising from conversion to
transportation service.  Firm transportation service increased due primarily to
a mainline expansion, supported by 15- year firm transportation service
contracts being placed into service on April 1, 1993.  Additionally, Pipeline
placed new, increased transportation rates into effect on April 1, 1993
(subject to refund) that reflected the new mainline expansion and a straight
fixed variable rate design that tends to moderate seasonal swings in operating
revenues.

      Operating expenses decreased $6.8 million, or 4%, primarily due to lower
natural gas purchase volumes and lower amortization of contract reformation
costs, partially offset by increased operation and maintenance expenses,
increased depreciation and amortization expenses and increased taxes other than
income taxes.  Operation and maintenance expenses increased $3 million due
primarily to higher employee related expenses and pipeline maintenance costs.
Depreciation and amortization increased $6.8 million as a result of completion
of the mainline expansion and other capital projects.  Taxes other than income
taxes increased $1.6 million due primarily to higher property taxes reflecting
the completion of the mainline expansion and other capital projects.
Amortization of contract reformation costs decreased $3.9 million due to full
amortization of the balance of direct billed contract reformation in 1992 and
disallowance of certain contract reformation costs by the FERC, offset by a
similar decrease in operating revenues.

      Operating income increased $31.9 million, or 47%, primarily due to
increased firm transportation service and higher average transportation rates.

      Other income reflects a $4 million decrease in the equity component of
the allowance for funds used during construction attributed to the completion
of Pipeline's mainline expansion and other capital projects.

      Interest on long-term debt increased $12 million due to issuance of $150
million in debentures during the third quarter of 1992 and the allocation of
interest expense to discontinued operations in 1992.  Other interest expense
increased $2.6 million primarily due to the amortization of previously deferred
carrying costs on contract reformation.

      The increase in the effective tax rate is a result of the cumulative
effect of the 1% increase in the Federal income tax rate.

FINANCIAL CONDITION AND LIQUIDITY

Capital Expenditures and Financing

      Pipeline's expenditures for property, plant and equipment additions for
continuing operations amounted to $62.6 million, $175.7 million and $297.6
million for 1994, 1993 and 1992, respectively.  Funds necessary to complete
capital projects are expected to come from several sources, including
Pipeline's operations and available cash.  In addition, Pipeline expects to be
able to obtain financing, when necessary, on reasonable terms.  To allow
flexibility in the timing of issuance of long-term securities, financing may be
provided on an interim basis with bank debt and from sources discussed below.

      Pipeline believes that strong economies in the Pacific Northwest and the
growing preference for natural gas in response to environmental concerns
support future expansions of its mainline capacity.  In August 1993, Pipeline
filed applications for FERC approval to build additional mainline expansions
totaling 360 MMcf of gas per day of system capacity.  In order to assure
unneeded incremental capacity was not constructed, in March 1994 Pipeline
allowed expansion shippers to reduce their contracted level of service.  As a
result, Pipeline filed an amended certificate reducing the expansions to 164
MMcf of gas per day of increased system capacity at an estimated cost of $99.5
million to be in service by the end of 1995.  Most of the expansion shippers
reducing their contracted level of service were able to obtain needed service
through readily available firm segmented capacity releases under FERC Order No.
636 that Pipeline implemented on November 1, 1993.  Other opportunities include
the construction of $15 million of lateral and meter station expansions to meet
existing customer's shifting demand patterns under Order No. 636.

      Pipeline participated in a $600 million Revolving Credit Agreement with
Williams and two affiliated companies.  Pipeline's maximum borrowing
availability, subject to prior borrowing by other affiliated companies, was
$300 million, none of which was used by Pipeline at December 31, 1994 or 1993.
Interest rates vary with current market conditions.  The agreement contains
restrictions that limit, under certain circumstances, the issuance of
additional debt, the attachment of liens on any assets and any change of
ownership of Pipeline.  Effective February 23, 1995, this agreement was
renegotiated to an $800 million Revolving Credit Agreement with Williams and
three affiliated companies, with Pipeline's maximum borrowing availability,
subject to prior borrowing by other affiliated companies, increasing to $400
million.  Other terms and restrictions remain essentially the same.

      Pipeline has also arranged various uncommitted lines-of-credit at market
interest rates.  Pipeline's credit facilities are subject to Pipeline's
continued credit worthiness.

OTHER

      Pipeline owns and operates an interstate natural gas pipeline system
including facilities for mainline transmission and gas storage.  Pipeline's
transmission and storage activities are subject to regulation by the FERC under
the Natural Gas Act of 1938 and under the Natural Gas Policy Act  of 1978, and,
as such, its rates and charges for the transportation, the extension,
enlargement or abandonment of its jurisdictional facilities, and its
accounting, among other things, are subject to regulation.

      Pipeline is also subject to the National Environmental Policy Act and
other Federal and state legislation regulating the environmental aspects of its
business.  Management believes that Pipeline is in substantial compliance with
existing environmental requirements.  Pipeline believes that, with respect to
any capital expenditures required to meet applicable standards and regulations,
FERC would grant the requisite rate relief so that, for the most part, such
expenditures and a return thereon would be permitted to be recovered.  Pipeline
believes that compliance with applicable environmental requirements is not
likely to have a material effect upon Pipeline's earnings or competitive
position.

      On April 1, 1993, Pipeline began collecting new rates, subject to refund,
under the provisions of its rate case filed October 1, 1992.  On July 28, 1994,
Pipeline received an initial decision from an ALJ on this rate case.  This
decision will be considered by the FERC prior to its issuance of a final order.
Pipeline has raised exceptions with the FERC to the ALJ decision and is
awaiting the FERC's final order.  Pipeline believes the outcome of the final
order is not likely to have a significant effect on net income.

      On November 1, 1994, Pipeline began collecting new rates, subject to
refund, under the provisions of its rate case filed April 29, 1994.  This new
filing seeks a revenue increase for a projected deficiency caused by increased
costs and loss of cost recovery assigned to a transportation contract
terminated subsequent to the rate case filed on October 1, 1992.

      See Note 3 of Notes to Financial Statements for fair value of financial
instruments and Note 8 for the effects of a new accounting standard on other
postretirement and postemployment benefits.

Effect of Inflation

      Pipeline generally has experienced increased costs in recent years due to
the effect of inflation on the cost of labor, material and supplies, and plant
and equipment.  A portion of the increased labor and material and supplies cost
can directly affect income through increased maintenance and operating costs.
The cumulative impact of inflation over a number of years has resulted in
increased costs for current replacement of productive facilities.  The majority
of Pipeline's plant and equipment and inventory is subject to ratemaking
treatment, and under current FERC practices, recovery is limited to historical
costs.  While amounts in excess of historical cost are not recoverable under
current FERC practices, Pipeline believes it will be allowed to recover and
earn a return based on increased actual cost incurred when existing facilities
are replaced.  Cost based regulation along with competition and other market
factors limit Pipeline's ability to price services or products based upon
inflation's effect on costs.

Contingencies

information about regulatory and judicial developments which cause operating
and financial uncertainties.

                         REPORT OF INDEPENDENT AUDITORS




The Board of Directors
Northwest Pipeline Corporation


     We have audited the accompanying balance sheet of Northwest Pipeline
Corporation as of December 31, 1994 and 1993, and the related statements of
income, cash flows and capitalization 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, the financial statements referred to above present fairly,
in all material respects, the financial position of Northwest Pipeline
Corporation at December 31, 1994 and 1993, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1994, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

================================================================================

(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Northwest Pipeline Corporation ("Pipeline") is wholly owned by The
Williams Companies, Inc. ("Williams").


Property, Plant and Equipment

      Property, plant and equipment ("plant"), consisting principally of
natural gas transmission facilities, is recorded at original cost.
Expenditures which materially increase values or capacities or extend useful
lives of plant are capitalized.  Routine maintenance, repairs and renewal costs
are charged to income as incurred.  Gains or losses from the ordinary sale or
retirement of plant are charged or credited to accumulated depreciation and
amortization ("D&A").

      Depreciation is provided by the straight-line method for transmission
plant over its useful life.  The composite annual D&A rate was 2%, 2.13% and
3.05% for 1994, 1993 and 1992, respectively.

Allowance for Borrowed and Equity Funds Used During Construction

      Allowance for funds used during construction ("AFUDC") represents the
estimated cost of borrowed and equity funds applicable to utility plant in
process of construction.  Recognition is made of this item as a cost of utility
plant because it constitutes an actual cost of construction under established
regulatory practices.  The Federal Energy Regulatory Commission ("FERC") has
prescribed a formula to be used in computing separate allowances for borrowed
and equity AFUDC.

      The composite rate used to capitalize AFUDC was approximately 11.8% for
1994 and 1993 and 12.2% for 1992.  Equity AFUDC of $1.3 million, $6.1 million
and $10.1 million for 1994, 1993 and 1992, respectively, is reflected in other
income.

Income Taxes

      Pipeline is included in Williams' consolidated federal income tax return.
Pipeline's Federal income tax provisions are computed as though separate tax
returns are filed.  Deferred income taxes are computed using the liability
method and are provided on all temporary differences between the financial
basis and the tax basis of Pipeline's assets and liabilities.

Deferred Charges

      Pipeline amortizes deferred charges over varying periods consistent with
FERC approved accounting treatment for such deferred items.  Unamortized debt
expense, debt discount and gains or losses on reacquired long-term debt are
amortized by the bonds outstanding method over the related debt repayment
periods.

                   NOTES TO FINANCIAL STATEMENTS - CONTINUED
================================================================================

Deferred Credits

      The regulatory liability, recorded as a result of new accounting
principles for income taxes was adjusted to reflect the increase in the Federal
income tax rate from 34 percent to 35 percent in 1993.  This liability of $10.2
million and $11.3 million at December 31, 1994 and 1993, respectively, is
reflected in other deferred credits.  The regulatory liability is being
amortized over the lives of the related depreciable assets.

Cash and Cash Equivalents

      Cash and cash equivalents include demand and time deposits, certificates
of deposit and other marketable securities with a term to maturity of three
months or less when acquired.

Revenue Recognition

      Pipeline recognizes revenues for the transportation of natural gas based
upon contractual terms and the related transported volume through month end.
Pursuant to FERC regulations, a portion of the revenues being collected may be
subject to possible refunds upon final orders in pending cases.  Pipeline
establishes financial reserves for such contingencies based on the facts and
circumstances of the pending case.

Environmental Matters

      Pipeline is subject to Federal, state, and local environmental laws and
regulations.  Environmental expenditures are expensed or capitalized depending
on their future economic benefit and potential for rate recovery.  Pipeline
believes that, with respect to any expenditures required to meet applicable
standards and regulations, FERC would grant the requisite rate relief so that,
for the most part, such expenditures would be permitted to be recovered.
Pipeline believes that compliance with applicable environmental requirements is
not likely to have a material effect upon Pipeline's financial position.

Interest Payments

      Cash payments for interest were $28.9 million, $26.8 million and $16.5
million, net of $1 million, $4.7 million and $5.7 million of interest
capitalized in 1994, 1993 and 1992, respectively.  Of these amounts, $4.5
million, net of $1.6 million of interest capitalized was allocated to

      Pipeline's long-term debt for this period cannot be specifically sourced
to gathering and processing even though these assets were financed
historically, at least in part, with overall debt obligations of Pipeline.
Therefore, the amount of interest allocated to discontinued operations for
purposes of this restatement is based on the ratio of all gathering and
processing assets, net of all gathering and processing liabilities to total
assets, net of total liabilities (except long-term debt).


(3)   DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of SFAS No. 107,
Disclosures About Fair Value of Financial Instruments.  The estimated fair
value amounts have been determined by Pipeline, using available market
information and appropriate valuation methodologies.  However, considerable
judgement is necessarily required in interpreting market data to develop the
estimates of fair value.  Accordingly, the estimates presented herein are not
necessarily indicative of the amounts that Pipeline could realize in a current
market exchange.  The use and complexity of different market assumptions and/or
estimation methodologies may have a material effect on the estimated fair value
amounts.

================================================================================


      The following methods and assumptions were used to estimate the fair
value of each class of financial instruments for which it is practicable to
estimate that value:

Cash and cash equivalents, advances to parent, accounts receivable, and
accounts payable - The carrying amount of these items are assumed to be
indicative of their fair value.

Long-term debt - The fair value of Pipeline's publicly traded long-term debt is
valued using year-end traded market prices.  Private debt is valued based on
the prices of similar securities with similar terms and credit ratings.
Pipeline used the expertise of an outside investment banking firm to estimate
the  fair value of long-term debt.

      The carrying amount and estimated fair value of Pipeline's long term
debt, including current maturities, were $306.3 million and $314.3 million,
respectively, at December 31, 1994, and $319.3 million and $351.5 million,
respectively, at December 31, 1993.


(4)   REVENUES ATTRIBUTABLE TO MAJOR CUSTOMERS

      During some or all of the periods presented, more than 10% of Pipeline's
operating revenues were generated from each of the following customers who are
large distribution companies.

      Pipeline's major customers are located in the Pacific Northwest.  As a
general policy, collateral is not required for receivables, but customers'
financial condition and credit worthiness are regularly evaluated and
historical losses have been minimal.  A portion of the revenues reflected above
(subsequent to April 1, 1993) may be subject to refund due to Pipeline's
pending rate cases as discussed in Note 10.

      The provision for income taxes from discontinued operations was allocated
based on Pipeline's overall effective tax rate for the respective periods.  Net
cash payments, including discontinued operations, made to Williams for income
taxes were $22.7 million, $36.2 million and $47.3 million in 1994, 1993 and
1992, respectively.

(6)   RETAINED EARNINGS

Noncash Dividends

      On December 31, 1992, Pipeline transferred its gathering and processing
properties and certain other assets and liabilities to Processing.  On the same
date, the stock of Processing was transferred by dividend to Pipeline's parent,
Williams.  The assets and liabilities transferred consisted of all the
gathering and processing properties of Pipeline and related liabilities, net of
associated deferred income tax liabilities.  The total amount of this dividend
was $163.1 million.

      On December 31, 1993, Pipeline transferred certain aircraft and computer
assets, net of associated deferred income tax liabilities, to Williams by
dividend.  These assets, which are not included in the accompanying balance
sheet as of December 31, 1993, had a net book value of $1.4 million.

      On January 31, 1994, Pipeline transferred certain telecommunication and
measurement assets, net of associated deferred income tax liabilities, to
Williams by dividend.  These assets, which are not included in the accompanying
balance sheet as of December 31, 1994, had a net book value of $.9 million.

      On September 30, 1994, Pipeline transferred certain gas transmission
assets located in Oklahoma, net of associated deferred income tax liabilities,
to Williams by dividend.  These assets, which are not included in the
accompanying balance sheet as of December 31, 1994, had a net book value of $.7
million.

Restrictions

      Pipeline's debt indentures contain provisions limiting common stock
dividends.  Under the most restrictive provisions, the amount of Pipeline's
retained earnings available for dividends on its common stock as of December
31, 1994, was approximately $150.5 million.

(7)   LONG-TERM DEBT, LEASES AND BANKING ARRANGEMENTS

Debt Covenants

      The terms of Pipeline's debt indentures preclude the issuance of mortgage
bonds.  The indentures contain provisions for the acceleration of repayment or
the reset of interest rates under certain conditions.  Pipeline's debt
indentures also contain restrictions which, under certain circumstances, limit
the issuance of additional debt, restrict the payment of cash dividends and
restrict the disposal of a major portion of its natural gas pipeline system.

Long-Term Debt

      On April 29, 1993, Pipeline called the balance of its outstanding 8.75%
Series A Debentures, due 1996, under terms of the optional prepayment
provisions in the debenture agreement.  On the prepayment date of June 1, 1993,
the debenture holders were paid the principal amount of $8.7 million plus early
redemption premiums of $.2 million.  The prepayment was in addition to the May
31, 1993 sinking fund payment of $5.8 million and an optional, partial sinking
fund payment of $2.9 million.  The redemption premium and the unamortized debt
expense associated with the 8.75% Series A Debentures, totaling approximately
$.2 million, will be amortized over the original life of the debt as required
by the FERC.

      On April 29, 1993, Pipeline also called $5 million of its outstanding 9%
Series B Debentures, due 2001, under terms of the optional prepayment
provisions in the debenture agreement.  No early redemption premium was
required.  The prepayment was in addition to the May 31, 1993 sinking fund
payment of $5 million.

      On April 27, 1994, Pipeline called $2.5 million of its outstanding 9%
Series B Debentures and $1.9 million of its outstanding 9.25% Series C
Debentures, due 2001 and 2006, respectively, under terms of the optional
prepayment provisions in the debenture agreement.  No early redemption premium
was required.  The prepayment was in addition to the May 31, 1994 sinking fund
payments of $5 million for the 9% Series and $1.9 million for the 9.25% Series.

Line-of-Credit Arrangements

     Pipeline participated in a $600 million Revolving Credit Agreement with
Williams and two affiliated companies.  Pipeline's maximum borrowing
availability, subject to prior borrowing by other affiliated companies, was
$300 million, none of which was used by Pipeline at December 31, 1994 or 1993.
Interest rates vary with current market conditions.  The agreement contains
restrictions that limit, under certain circumstances, the issuance of
additional debt, the attachment of liens on any assets and any change of
ownership of Pipeline.  Effective February 23, 1995, this agreement was
renegotiated to an $800 million Revolving Credit Agreement with Williams and
three affiliated companies, with Pipeline's maximum borrowing availability,
subject to prior borrowing by other affiliated companies, increasing to $400
million.  Other terms and restrictions remain essentially the same.

     Pipeline has also arranged various uncommitted lines-of-credit at market
interest rates.  Pipeline's credit facilities are subject to Pipeline's
continued credit worthiness.

Leases

      Pipeline's leasing arrangements include mostly premise and equipment
leases that are classified as operating leases.

      The major operating lease is a leveraged lease which became effective
during 1982 for Pipeline's headquarters building.  The agreement has an initial
term of approximately 27 years, with options for consecutive renewal terms of
approximately 9 years and 10 years.  The major component of the lease payment
is set through the initial and first renewal terms of the lease except for a
potential one time adjustment in 1995 to track an allowed interest rate change
on a portion of the lessor's debt.  Various purchase options exist under the
building lease, including options involving adverse regulatory development.

      Following are the estimated future  minimum yearly rental payments
required under operating leases which have initial or remaining noncancelable
lease terms in excess of one year:

      Operating lease rental expense, net of amounts applicable to discontinued
operations for 1992 amounted to $4.6 million, $4.3 million and $3.4 million for
1994, 1993 and 1992, respectively.  Capital lease payments for the periods
presented are not significant.

(8)   EMPLOYEE BENEFIT PLANS

      Pipeline's employees are covered by Williams' noncontributory defined
benefit pension plan.  Benefits are based on years of service and average final
compensation.  Pension costs are funded to satisfy minimum requirements
prescribed by the Employee Retirement Income Security Act of 1974.  Pipeline
accrued pension expense of $.5 million in 1994 and $1.1 million in each of the
years 1993 and 1992.  Such accrued expenses have been or are being funded
currently.

================================================================================

      Substantially all retirees who were hired prior to January 1, 1992, are
provided medical benefits.   Employees hired after January 1, 1992 will not be
provided postretirement medical benefits.  As of January 1, 1993, Northwest
Pipeline adopted SFAS No. 106, "Employers' Accounting for Postretirement
Benefits Other than Pensions".  During 1994, 1993 and 1992 the expense of
providing medical benefits to retirees was approximately $2.8 million, $2.8
million and $1.7 million, respectively.  Included in 1994 and 1993 expenses is
the amortization of Pipeline's estimated transition obligation of $19.2 million
which is being amortized prospectively over 20 years.

      In December 1992, FERC issued a Statement of Policy allowing natural gas
pipelines to recognize, as a component of jurisdictional cost-based rates,
prudently incurred SFAS No. 106 costs, provided that amounts accrued under SFAS
No. 106 are fully funded with an irrevocable external trust fund and that
income tax deductions for contributions to the trust fund are maximized.
Northwest Pipeline has complied with this Statement of Policy.

      Effective January 1, 1994 Pipeline adopted Statement of Financial
Accounting Standards ("SFAS") No. 112, "Employers' Accounting for
Postemployment Benefits", which requires the accrual of benefits provided to
former or inactive employees after regular employment but before retirement.
The adoption of the new standard had no effect on Pipeline's net income and had
no significant effect on Pipeline's balance sheet.

      Williams maintains various defined contribution plans covering
substantially all employees.  Company contributions are based on employees'
compensation and, in part, match employee contributions.  All Company
contributions are invested in Williams stock.  Contributions by Pipeline to
these plans totaled $1.8 million for each of the years 1994, 1993 and 1992.

(9)   RELATED PARTY TRANSACTIONS

      Williams' corporate overhead expenses allocated to Pipeline were $4.6
million, $4.2 million and $6.4 million for 1994, 1993 and 1992, respectively,
of which $2.4 million was allocated to discontinued operations for 1992.  Such
expenses have been allocated to Pipeline by Williams, primarily based on the
Massachusetts formula, which is a FERC approved method utilizing a combination
of operating revenues, gross payroll and gross plant for the allocation base.
In addition, Williams or an affiliate has provided executive, data processing,
legal, aviation, internal audit and other administrative services to Pipeline
on a direct charge basis which amounted to $3.4 million, $4.9 million and $5.4
million for 1994, 1993 and 1992, respectively, of which $2 million was charged
to discontinued operations in 1992.  Corporate overhead allocated and direct
administrative services, representative of the amounts allocated/charged to
discontinued operations, continue to be allocated/charged to Processing since
the transfer described in Note 2.  In addition, Pipeline received interest
income from advances to parent of $1.2 million and $2.3 million during 1994 and
1992, respectively.  There were no advances to parent during 1993.

      During the periods presented, Pipeline's revenues reflect gas sales,
transportation and exchange transactions with subsidiaries of Williams.
Combined revenues for these activities totaled $3.4 million, $4.8 million and
$16.8 million for 1994, 1993 and 1992, respectively.  Liquids products
extracted from Pipeline's gas processing plants (discontinued operations) were
marketed by a subsidiary of Williams for a fee.  Such commissions were $2.1
million in 1992.

      Pipeline has entered into various other transactions with certain related
parties, the amounts of which were not significant.  These transactions and the
above described transactions are charged on the basis of commercial
relationships and prevailing market prices or general industry practices.

(10)  CONTINGENT LIABILITIES AND COMMITMENTS

Contract Reformation

      Pursuant to FERC policy, Pipeline filed to recover a portion of contract
reformation costs through direct bills to former sales customers and through
surcharges to transportation as well as sales commodity rates.  The total
amount of contract reformation costs authorized by FERC to be collected by
Pipeline by means of a direct bill mechanism was $34 million.  All amounts have
been recovered at December 31, 1994.

      FERC initially approved Pipeline's use of a mechanism to direct bill
Pipeline's contract reformation costs, but when challenged on appeal, sought a
remand to reassess its order concerning the billing mechanism.  Pipeline has
received an order from FERC that requires Pipeline to reallocate such contract
reformation costs using a different method.  Although reallocation will require
refunds of certain amounts, it is expected that Pipeline will be permitted to
recover substantially all of these costs from other customers.

Pending Rate Cases

      On April 1, 1993, Pipeline began collecting new rates, subject to refund,
under the provisions of its rate case filed October 1, 1992.  On July 28, 1994,
Pipeline received an initial decision from an Administrative Law Judge ("ALJ")
on this rate case.  This decision will be considered by the FERC prior to its
issuance of a final order.  Pipeline has raised exceptions with the FERC to the
ALJ decision and is awaiting the FERC's final order.  Pipeline believes the
outcome of the final order is not likely to have a significant effect on net
income.

      On November 1, 1994, Pipeline began collecting new rates, subject to
refund, under the provisions of its rate case filed April 29, 1994.  This new
filing seeks a revenue increase for a projected deficiency caused by increased
costs and loss of cost recovery assigned to a transportation contract
terminated subsequent to the rate case filed on October 1, 1992.

================================================================================

Other Regulatory Matters

       In 1989, the FERC issued an order to Pipeline instituting a formal
investigation related to the assignment by Pipeline of certain gas supply
contracts to an affiliate.  Pipeline was ordered to show cause why the
assignments did not violate certain federal statutes and FERC regulations.  By
order dated October 5, 1992, the FERC set the matter for an expedited hearing
before an Administrative Law Judge ("ALJ").  The ALJ issued a decision in favor
of Pipeline on May 13, 1993.  On April 6, 1994, the FERC issued an order
terminating all proceedings and affirming the ALJ's May 13, 1993 decision in
favor of Pipeline.

Other Legal Matters

       In addition to the foregoing, various other proceedings are pending
against Pipeline incidental to its operations.

Summary of Contingent Liabilities

       Management believes that the ultimate resolution of the foregoing
matters, after consideration of amounts accrued, insurance coverage or other
indemnification arrangements, is not likely to have a materially adverse
financial effect upon Pipeline in the future.


Other Matters

       Commitments for construction and acquisition of property, plant and
equipment are approximately $19.1 million at December 31, 1994.

       During 1994 Pipeline sold, with limited recourse, certain receivables.
Until the expiration of the arrangement in July 1994, net proceeds to Pipeline
were limited to $40 million, none of which was utilized at the expiration date
or at December 31, 1993.  During 1994, Pipeline utilized this facility at
varying times up to $18 million.

transportation service.
