PART I

ITEM 1. BUSINESS

(A) GENERAL DEVELOPMENT OF BUSINESS

Williams Holdings of Delaware, Inc. was incorporated under the laws of the State of Delaware in 1994. The principal executive offices of Williams Holdings are located at One Williams Center, Tulsa, Oklahoma 74172 (telephone (918) 573-2000). Unless the context otherwise requires, references to Williams Holdings herein include its subsidiaries. Williams Holdings is a wholly owned subsidiary of The Williams Companies, Inc. (Williams).

On March 24, 1999, Williams disclosed that its Board of Directors had authorized the merger of Williams Holdings with and into Williams and the assumption by Williams of liabilities and obligations of Williams Holdings. Management expects the merger to be completed in the second or third quarter of 1999.

On November 19, 1998, Williams announced that its board of directors had authorized an initial public offering of a minority interest in its communications subsidiary, Williams Communications Group, Inc. Williams expects to file a registration statement for this offering with the Securities and Exchange Commission in the second quarter of 1999. In addition, on February 8, 1999, Williams announced it had entered into an agreement with SBC Communications under which SBC would acquire the lesser of the number of shares of common stock valued at $500 million or ten percent of the common stock of Williams Communications in a private placement expected to occur simultaneously with the initial public offering.

On March 28, 1998, Williams acquired MAPCO Inc. in a stock-for-stock transaction based upon a fixed exchange ratio of 1.665 shares of Williams common stock and .555 associated preferred stock purchase rights for each share of MAPCO common stock and associated preferred stock purchase rights. See Note 2 to Notes to Consolidated Financial Statements. Management believes the acquisition furthers its strategy of seeking growth through strategic acquisitions and alliances and that MAPCO's assets and operations complement Williams' existing lines of business. Williams operates the MAPCO businesses through Williams Energy Services.

A business description of each of Williams Energy's business units follows.

EXPLORATION & PRODUCTION

Williams Energy, through its wholly owned subsidiary Williams Production Company in its Exploration & Production unit (E&P), owns and operates producing natural gas leasehold properties in the United States. In addition, E&P is actively exploring for oil and gas.

Oil and gas properties. E&P's properties are located primarily in the Rocky Mountains and Gulf Coast areas. Rocky Mountain properties are located in the San Juan Basin in New Mexico and Colorado, in Wyoming, and in Utah. Gulf Coast properties are located in Louisiana, east and south Texas, and offshore Gulf of Mexico.

Gas Reserves. At December 31, 1998, 1997, and 1996, E&P had proved developed natural gas reserves of 476 Bcf, 362 Bcf, and 323 Bcf, respectively, and proved undeveloped reserves of 232 Bcf, 238 Bcf, and 208 Bcf, respectively. Of E&P's total proved reserves, 90 percent are located in the San Juan Basin of Colorado and New Mexico. No major discovery or other favorable or adverse event has caused a significant change in estimated gas reserves since year end.

Customers and Operations. At December 31, 1998, the gross and net developed leasehold acres owned by E&P totaled 312,939 and 131,303, respectively, and the gross and net undeveloped acres owned were 444,916 and 111,926, respectively. At December 31, 1998, E&P owned interests in 3,393 gross producing wells (632 net) on its leasehold lands.

Operating Statistics. The following tables summarize drilling activity for the periods indicated:

The majority of E&P's gas production is currently being sold in the spot market at market prices. Total net production sold during 1998, 1997, and 1996 was 43.2 Bcf, 37.1 Bcf, and 31.0 Bcf, respectively. The average production costs, including production taxes, per Mcf of gas produced were $.37, $.42, and $.23, in

3

1998, 1997, and 1996, respectively. The average wellhead sales price per Mcf was $1.31, $1.62, and $.98, respectively, for the same periods.

In 1993 E&P conveyed a net profits interest in certain of its properties to the Williams Coal Seam Gas Royalty Trust. Williams subsequently sold Trust Units to the public in an underwritten public offering. Williams Holdings owns 3,568,791 Trust Units representing 36.8 percent of outstanding Units. Substantially all of the production attributable to the properties conveyed to the Trust was from the Fruitland coal formation and constituted coal seam gas. Production information reported herein includes E&P's interest in these Units.

MIDSTREAM GAS & LIQUIDS

Williams Energy, through Williams Field Services Group, Inc. and its subsidiaries (Midstream Gas & Liquids), owns and operates natural gas gathering, processing, treating, transportation, fractionation, and storage facilities located in northwestern New Mexico, southwestern Colorado, southwestern Wyoming, eastern Utah, northwestern Oklahoma, Kansas, northern Missouri, eastern Nebraska, Iowa, southern Minnesota, Tennessee, and also in areas offshore and onshore in Texas, Alabama, Mississippi, and Louisiana. Midstream Gas & Liquids also operates gathering facilities, owned by Transcontinental Gas Pipe Line Corporation, an affiliated interstate natural gas pipeline company, that are currently regulated by the FERC.

As a result of the MAPCO merger in 1998, Williams Energy acquired an approximately 4.8 percent investment interest in Alliance Pipeline. Effective January 1, 1999, this interest was transferred to subsidiaries of the Williams Companies, Inc. Alliance consists of two proposed segments, a Canadian segment and a United States segment. Alliance has filed applications for approval with the FERC in the United States and the National Energy Board (NEB) in Canada, to construct and operate an approximately 1,800 mile natural gas pipeline system extending from northeast British Columbia to the Chicago, Illinois, area market center, where it will interconnect with the North American pipeline grid. On September 17, 1998, the FERC granted a Certificate of Public Convenience and Necessity (CPCN) for the United States portion of the Alliance pipeline, and on December 3, 1998, the NEB granted a CPCN for the Canadian portion. Construction is expected to begin in the spring of 1999 with an anticipated in-service date of October 2000. Total estimated cost of the Alliance project is approximately $3 billion. At December 31, 1998, Williams Energy had invested approximately $19 million in Alliance.

Expansion Projects. During 1998 Midstream Gas & Liquids continued to expand its operations in the Gulf Coast region through the Mobile Bay and Discovery projects. Discovery, a 50 percent owned joint venture, began operations during 1997 with the completion of its 150-mile gas gathering system, Larose cryogenic plant with 600 MMcf per day of capacity, and Paradis fractionation facility with 42,000 bbl per day of capacity. Construction on the Mobile Bay gathering and processing facilities has remained on schedule, with the processing plant's commissioning and performance testing expected to begin in the second quarter of 1999. Contracts are currently in place to supply approximately 70 percent of the processing plant's 600 MMcf per day of capacity. Liquids from this plant will be handled by three separate joint ventures including the Tri-States Pipeline, a 16.7 percent owned system with a capacity of 80,000 bbl per day, Wilprise Pipeline, a 33 percent owned system with capacity of 75,000 bbl per day, and a 26.7 percent owned fractionation facility with a capacity of 60,000 bbl per day. In addition, Midstream Gas & Liquids began construction on an expansion of its Rocky Mountain natural gas liquids pipeline which will increase capacity from 75,000 bbl per day to 125,000 bbl per day through construction of a 412-mile pipeline parallel to the existing Mid-America System. Completion is expected in July 1999.

Customers and Operations. Facilities owned and operated by Midstream Gas & Liquids consist of approximately 7,500 miles of gathering pipelines and owns or operates ten gas treating plants and 11 gas processing plants (one of which is partially owned), and approximately 10,300 miles of natural gas liquids pipeline, of which approximately 1,600 miles are partially owned. The aggregate daily inlet capacity is approximately 7.9 Bcf for the gathering systems and 6.7 Bcf for the gas processing, treating, and dehydration facilities. Midstream Gas & Liquids' pipeline operations provide customers with one of the nation's largest NGL transportation systems, while gathering and processing customers have direct access to interstate pipelines, including affiliated pipelines, which provide access to multiple markets.

4

During 1998 Midstream Gas & Liquids gathered gas for 288 customers, processed gas for 140 customers, and provided transportation to 87 customers. The two largest customers accounted for approximately 24 percent and 11 percent, respectively, of total gathered volumes, and the largest customer accounted for approximately 23 percent of processed volumes. The two largest transportation customers accounted for 23 percent and 12 percent, respectively, of transportation volumes. No other customer accounted for more than ten percent of gathered, processed, or transported volumes. Midstream Gas & Liquids' gathering and processing agreements with large customers are generally long-term agreements with various expiration dates. These long-term agreements account for the majority of the gas gathered and processed by Midstream Gas & Liquids. The natural gas liquids transportation contracts are tariff-based and generally short-term in nature with some long-term contracts for system-connected processing plants.

Operating Statistics. The following table summarizes gathering, processing, natural gas liquid sales, and transportation volumes for the periods indicated.

                                                              1998    1997    1996

PETROLEUM SERVICES

Williams Energy, through wholly owned subsidiaries in its Petroleum Services unit, owns and operates a petroleum products pipeline system, two ethanol production plants (one of which is partially owned), and petroleum products terminals and provides services and markets products related thereto. Included in this business unit are two refineries, 256 convenience stores/travel centers, trucking and rail operations for propane and refined products, mobile information management systems, and fleet fuel management services.

Transportation. A subsidiary in the Petroleum Services unit, Williams Pipe Line Company, owns and operates a petroleum products pipeline system which covers an 11-state area extending from Oklahoma to North Dakota and Minnesota and Illinois. The system is operated as a common carrier offering transportation and terminalling services on a nondiscriminatory basis under published tariffs. The system transports refined products and liquefied petroleum gases.

At December 31, 1998, the system traverses approximately 7,100 miles of right-of-way and includes approximately 9,100 miles of pipeline in various sizes up to 16 inches in diameter. The system includes 77 pumping stations, 22.4 million barrels of storage capacity, and 39 delivery terminals. The terminals are equipped to deliver refined products into tank trucks and tank rail cars. The maximum number of barrels that the system can transport per day depends upon the operating balance achieved at a given time between various segments of the system. Because the balance is dependent upon the mix of products to be shipped and the demand levels at the various delivery points, the exact capacity of the system cannot be stated. In 1998 total system shipments averaged 614 thousand barrels per day.

An affiliate of Williams Pipe Line, Longhorn Enterprises of Texas, Inc. (LETI), owns a 31.5 percent interest in Longhorn Partners Pipeline, LP, a joint venture formed to construct and operate a refined products pipeline from Houston to El Paso, Texas. Pipeline construction is nearly complete, but operations are not expected to commence until the third quarter of 1999, pending review and approval of an environmental assessment. Williams Pipe Line has designed and constructed and will operate the pipeline, and LETI has contributed a total of $92.4 million to the joint venture.

On February 25, 1999, Williams Energy announced it had reached an agreement to purchase Union Texas Petrochemicals Corporation, a wholly owned subsidiary of ARCO, with a closing expected on March 31, 1999. UTP's assets include a 215-mile light hydrocarbon transportation and 85-mile olefin pipeline and storage network, which connects, either directly or indirectly, most major natural gas liquids producers and olefin consumers in Louisiana. UTP also is the leading merchant marketer of ethylene in Louisiana and

5

owns and operates a 5/12th interest in a 1.25 billion pounds per year ethylene plant near Geismar, Louisiana. In connection with the acquisition, the Energy Marketing & Trading unit anticipates entering into a financial agreement, backed by an A credit-rated third party, intended to manage the risks related to the earnings volatility typically associated with ethylene production. The expected cost of this transaction is $166.5 million.

The operating statistics set forth below relate to the system's operations for the periods indicated:

                                                           1998      1997      1996

Terminal Services and Development. Williams Energy, through its wholly owned subsidiary Williams Energy Ventures, provides independent terminal services to the refining and marketing industries via distribution of petroleum products through wholly owned and joint interest terminals. WEV owns and/or operates 29 strategically located independent terminals covering a thirteen-state area in the South, Southeast, Southwest, and Midwest.

The terminals are supplied with refined products and ethanol by barge, tanker, truck, rail, and various common carrier pipelines. WEV provides scheduling and inventory management, access to an expanded transportation and information services network, additive injection services, and custom terminalling services such as octane and oxygenate blending. On a selective basis, WEV provides temporary leased storage.

In 1996 WEV acquired a 45.5 percent interest in eight Southeastern terminals and in 1998 increased that ownership percentage to 68.94 percent. In late 1997 WEV acquired a terminal in Dallas, Texas, and in 1998 acquired a terminal in Atlanta, Georgia. In early 1999 WEV purchased 12 terminals in the Southeast from Amoco and two Memphis, Tennessee, area terminals from Truman Arnold Companies. These acquisitions have allowed WEV to increase its core business and to offer multi-market terminal services to its customers.

Terminal barrels delivered for the periods indicated are noted below.

Distribution Services. Petroleum Services, through its distribution services group, provides petroleum trucking, propane trucking, and rail car operations for Williams Energy and third parties. The petroleum

6

trucking operation, operated out of Memphis, Tennessee, under the name "GENI Transport," works with local jobbers to supply their retail outlets and with several of Williams Energy's Energy Marketing & Trading unit's wholesale customers to develop transportation arrangements. GENI Transport is also the primary transportation provider to Petroleum Services' retail petroleum group. The propane trucking and rail car operations are the primary transportation providers for the Energy Marketing & Trading unit's retail propane group.

Refining. Petroleum Services, through its subsidiaries, owns and operates two refineries: the North Pole, Alaska, refinery and the Memphis, Tennessee, refinery.

North Pole Refinery. The North Pole Refinery includes the refinery located at North Pole, Alaska, and a terminal facility at Anchorage, Alaska. The refinery, the largest in the state, is located approximately two miles from its supply point for crude oil, the Trans-Alaska Pipeline System (TAPS). The refinery's processing capability is approximately 215,000 barrels per day. At maximum crude throughput, the refinery can produce 67,000 barrels per day of refined products. These products are jet fuel, gasoline, diesel fuel, heating oil, fuel oil, naphtha, and asphalt. Williams Energy's Energy Marketing & Trading unit markets these refined products in Alaska, Western Canada, and the Pacific Rim principally to wholesale, commercial, industrial, and governmental customers and Petroleum Services' retail petroleum group. The retail petroleum group accounted for about eight percent of the North Pole Refinery's 1998 product sales volume and 64 percent of the North Pole Refinery's gasoline production. Petroleum Services completed construction of a third crude unit at the refinery that can produce an additional 17,000 barrels per day of refined products, including 14,000 barrels per day of jet fuel. The new crude unit construction was completed in October 1998 at a cost of $74.5 million.

Average daily throughput and barrels processed and transferred by the North Pole Refinery are noted below:

                                                   1998      1997      1996

Barrels Processed and Transferred (bbl).........   44,561    42,201    43,392

The North Pole Refinery's crude oil is purchased through Williams Energy's Energy Marketing & Trading unit from the state of Alaska or is purchased or received on exchanges from crude oil producers. The refinery has a long-term agreement with the state of Alaska for the purchase of royalty oil, which is scheduled to expire on December 31, 2003. The agreement provides for the purchase of up to 35,000 barrels per day (approximately 17 percent of the refinery's supply) of the state's royalty share of crude oil produced from Prudhoe Bay, Alaska. These volumes, along with crude oil either purchased from crude oil producers or received under exchange agreements or other short-term supply agreements with the state of Alaska, are utilized as throughput in the production of products at the refinery. Approximately 34 percent of the throughput is refined and sold as finished product and the remainder of the throughput is returned to the TAPS and either delivered to repay exchange obligations or sold.

Memphis Refinery. The Memphis Refinery is the only refinery in the state of Tennessee and has a throughput capacity of approximately 140,000 barrels per day. In January 1998 Petroleum Services completed construction of a splitter, increasing the refinery's capacity for propylene production from 2,000 barrels per day to 6,000 barrels per day. In November 1998 Petroleum Services commissioned an expansion of its East Crude Unit, increasing crude production capacity by approximately 20,000 barrels per day to 140,000 barrels per day. Williams Energy is currently in the process of making significant plant modifications for further increasing the refinery's crude oil flexibility. In late 1998 a $123 million project to increase crude processing capacity of the refinery to 160,000 barrels per day and construct a 36,000 barrels per day continuous catalyst regeneration reformer was approved. Both projects are slated for completion in the year 2000 and will enable the refinery to produce 100 percent of customer demand for premium gasoline in the mid-South region of the United States while significantly enhancing crude flexibility.

7

The Memphis Refinery produces gasoline, low sulfur diesel fuel, jet fuel, K-1 kerosene, propylene, No. 6 fuel oil, propane, and elemental sulfur. These products are exchanged or marketed primarily in the Mid-South region of the United States by Williams Energy's Energy Marketing & Trading unit to wholesale customers, such as industrial, governmental, and commercial consumers, jobbers, independent dealers, other refiner/marketers, and to Petroleum Services' retail petroleum group.

The Memphis Refinery has access to crude oil from the Gulf Coast via common carrier pipeline and by river barges. In addition to domestic crude oil, the Memphis Refinery has the capability of receiving and processing certain foreign crudes. During 1998, following the MAPCO merger, Williams Energy's Energy Marketing & Trading unit purchased all of the crude oil processed at the Memphis Refinery. Although this method of purchase reduces the financial effect of volatile crude oil market prices, the financial results of the Memphis Refinery may be significantly impacted by changes in the market prices for crude oil and refined products. Petroleum Services cannot with any assurance predict the future of crude oil and product prices or their impact on its financial results.

Average daily barrels processed and transferred by the Memphis Refinery are noted below:

Retail Petroleum. Petroleum Services, primarily under the brand names "Williams TravelCenters" and "MAPCO Express," is engaged in the retail marketing of gasoline, diesel fuel, other petroleum products, convenience merchandise, and restaurant and fast food items. The retail petroleum group operates 29 interstate TravelCenter locations and 227 convenience stores. The TravelCenter sites consist of 11 modern facilities providing gasoline and diesel fuel, merchandise, and restaurant offerings for both traveling consumers and professional drivers, and 18 locations providing fuel and merchandise. The convenience store sites are primarily concentrated in the vicinities of Nashville and Memphis, Tennessee, and the state of Alaska. MAPCO Express stores represent 38 percent of the convenience store market in Alaska. All of the motor fuel sold by Williams TravelCenters and MAPCO Express stores is supplied either by exchanges, directly from either the Memphis or North Pole Refineries or through Williams Energy's Energy Marketing & Trading unit.

Convenience merchandise and fast food accounted for approximately 57 percent of the retail petroleum group's gross margins in 1998 and 55 percent in 1997. Gasoline and diesel sales volumes for the periods indicated are noted below:

ENERGY MARKETING & TRADING

Williams Energy, through subsidiaries, primarily Williams Energy Marketing & Trading Company and its subsidiaries (EM&T), is a national energy services provider that buys, sells, and transports a full suite of energy commodities, including natural gas, electricity, refined products, natural gas liquids, crude oil, propane, liquefied natural gas, and liquefied petroleum gas on a wholesale and retail level, serving over 300,000 customers. In addition, EM&T provides price-risk management services through a variety of financial instruments including exchange-traded futures, as well as over-the-counter forwards, options, and swap agreements related to various energy commodities and provides capital services to the diverse energy industry. See Note 16 of Notes to Consolidated Financial Statements.

EM&T markets natural gas throughout North America and grew its total volumes (physical and notional) to an average of 27.7 Bcf per day in 1998. EM&T's core business has traditionally been natural gas marketing in the Gulf Coast and Eastern regions of the United States, using the pipeline systems owned by Williams, but also includes marketing on approximately 50 non-Williams' pipelines. EM&T's natural gas customers include producers, industrials, local distribution companies, utilities, and other gas marketers.

8

In February 1999 EM&T and AES Ironwood, L.L.C. executed an amended and restated 20-year power purchase agreement under which EM&T is to provide fuel to and market up to approximately 655 megawatts of electricity output from a generating facility to be built and owned by AES in Southern Pennsylvania. In December 1998 EM&T reached agreement with Hoosier Energy Rural Electric Cooperative, Inc. to supply a part of its wholesale energy needs and manage its energy portfolio.

In May 1998 EM&T and The AES Corporation signed a 15-year agreement under which EM&T provides fuel to and markets up to approximately 4,000 megawatts of electricity output from three southern California generating sites with 14 units owned and operated by AES. During 1998 EM&T marketed 16.9 GW per hour (physical and notional) of electricity.

In 1998 EM&T provided supply, distribution, and related risk management services to petroleum producers, refiners, and end-users in the United States and various international regions. During 1998 EM&T's total crude and petroleum products (physical and notional) marketed averaged 2,153 Mbbl per day. During 1998 EM&T also marketed natural gas liquids with total volumes (physical and notional) averaging 480.3 Mbbl per day.

EM&T markets and distributes propane and appliances to approximately 300,000 customers at the retail level. Propane is used principally as a fuel in various domestic, commercial, industrial, agricultural, and vehicle motor fuel applications. Residential customers, who account for the majority of sales, use propane for home heating, cooking, and other domestic purposes. The primary agricultural use is crop drying. Commercial and industrial sales include fuel for shopping centers and industrial plants. During 1998 EM&T marketed 262.6 million gallons of propane.

EM&T is currently refocusing its retail natural gas and electric business to concentrate on large end-use customers and away from sales to commercial and residential customers. See Note 5 of Notes to Consolidated Financial Statements.

Operating Statistics. The following table summarizes marketing and trading volumes for the periods indicated, including propane totals during 1996, 1997, and a portion of 1998 during which Williams did not own MAPCO:

REGULATORY MATTERS

Midstream Gas & Liquids. In May 1994 after reviewing its legal authority in a Public Comment Proceeding, the FERC determined that while it retains some regulatory jurisdiction over gathering and processing performed by interstate pipelines, pipeline-affiliated gathering and processing companies are outside its authority under the Natural Gas Act. An appellate court has affirmed the FERC's determination and the United States Supreme Court has denied requests for certiorari. As a result of these FERC decisions, some of the individual states in which Midstream Gas & Liquids conducts its operations have considered whether to impose regulatory requirements on gathering companies. Kansas, Oklahoma, and Texas currently regulate gathering activities using complaint mechanisms under which the state commission may resolve disputes involving an individual gathering arrangement. Other states may also consider whether to impose regulatory requirements on gathering companies.

In February 1996 Midstream Gas & Liquids and Transco filed applications with the FERC to spindown all of Transco's gathering facilities to Midstream Gas & Liquids. The FERC subsequently denied the request in September 1996. Midstream Gas & Liquids and Transco sought rehearing in October 1996. In August 1997 Midstream Gas & Liquids and Transco filed a second request for expedited treatment of the rehearing request.

9

The FERC has yet to rule on this request for rehearing. In February 1998 Midstream Gas & Liquids and Transco filed a separate application to spindown an onshore gathering system located in Texas, the Tilden/ McMillen gathering system, which was also one of the subjects of the pending rehearing request. The FERC has not ruled on this request. In June 1998 the FERC issued a Notice of Inquiry into its policy related to pipeline facilities located on the Outer Continental Shelf. No policy or rule has been issued from that proceeding.

Midstream Gas & Liquids' natural gas liquids group is subject to various federal, state, and local environmental and safety laws and regulations. Midstream Gas & Liquids' pipeline operations are subject to the provisions of the Hazardous Liquid Pipeline Safety Act. In addition, the tariff rates, shipping regulations, and other practices of the Mid-America, Rio Grande, and Seminole pipelines are regulated by the FERC pursuant to the provisions of the Interstate Commerce Act applicable to interstate common carrier petroleum and petroleum products pipelines. The tariff rates and practices of the ammonia system are regulated by the Surface Transportation Board under the provisions of the Interstate Commerce Commission Termination Act of 1995 applicable to pipeline carriers. Both of these statutes require the filing of reasonable and nondiscriminatory tariff rates and subject Midstream Gas & Liquids to certain other regulations concerning its terms and conditions of service. The Mid-America, Rio Grande, and Seminole pipelines also file tariff rates covering intrastate movements with various state commissions. The United States Department of Transportation has prescribed safety regulations for common carrier pipelines. The pipeline systems are subject to various state laws and regulations concerning safety standards, exercise of eminent domain, and similar matters.

Petroleum Services. Williams Pipe Line, as an interstate common carrier pipeline, is subject to the provisions and regulations of the Interstate Commerce Act. Under this Act, Williams Pipe Line is required, among other things, to establish just, reasonable, and nondiscriminatory rates, to file its tariffs with the FERC, to keep its records and accounts pursuant to the Uniform System of Accounts for Oil Pipeline Companies, to make annual reports to the FERC, and to submit to examination of its records by the audit staff of the FERC. Authority to regulate rates, shipping rules, and other practices and to prescribe depreciation rates for common carrier pipelines is exercised by the FERC. The Department of Transportation, as authorized by the 1995 Pipeline Safety Reauthorization Act, is the oversight authority for interstate liquids pipelines. Williams Pipe Line is also subject to the provisions of various state laws applicable to intrastate pipelines.

On December 31, 1989, a rate cap, which resulted from a settlement with several shippers and had effectively frozen Williams Pipe Line's rates for the previous five years, expired. Williams Pipe Line filed a revised tariff on January 16, 1990, with the FERC and the state commissions. The tariff set an average increase in rates of 11 percent and established volume incentives and proportional rate discounts. Certain shippers on the Williams Pipe Line system and a competing pipeline carrier filed protests with the FERC alleging that the revised rates were not just and reasonable and were unlawfully discriminatory. Williams Pipe Line elected to bifurcate this proceeding in accordance with the then-current FERC policy. Phase I of the FERC's bifurcated proceeding provided Williams Pipe Line the opportunity to justify its rates and rate structure by demonstrating that its markets were workably competitive. Rates to markets that were not deemed workably competitive in Phase I required cost justification in Phase II. Subsequent rate increases filed by Williams Pipe Line were stayed pending ultimate resolution of Phase II.

In the Phase I proceeding, the FERC found all but 12 of Williams Pipe Line's markets to be workably competitive and, thus, eligible for market-based rates. On July 15, 1998, the FERC issued its decision in Phase II finding that Williams Pipe Line failed to demonstrate that the rates at issue for the 12 less competitive markets were just and reasonable and that Williams Pipe Line must roll back those rates to pre-1990 levels and pay refunds with interest to its shippers. Williams Pipe Line sought rehearing of the July 15, 1998, order and has been granted leave to stay the order's refund requirement until the FERC acts on rehearing. A shipper has appealed the Phase I order in the United States Court of Appeals for the District of Columbia Circuit and the appeal has been stayed pending the completion of Phase II. Williams Pipe Line took appropriate reserves in 1998 for the July 15, 1998, order, but continues to believe that subsequently revised tariffs will be found lawful. See Note 17 of Notes to Consolidated Financial Statements.

10

Environmental regulations and changing crude supply patterns continue to affect the refining industry. The industry's response to environmental regulations and changing supply patterns will directly affect volumes and products shipped on the Williams Pipe Line system. Environmental Protection Agency regulations, driven by the Clean Air Act, require refiners to change the composition of fuel manufactured. A pipeline's ability to respond to the effects of regulation and changing supply patterns will determine its ability to maintain and capture new market shares. Williams Pipe Line has successfully responded to changes in diesel fuel composition and product supply and has adapted to new gasoline additive requirements. Reformulated gasoline regulations have not yet significantly affected Williams Pipe Line. Williams Pipe Line will continue to attempt to position itself to respond to changing regulations and supply patterns but cannot predict how future changes in the marketplace will affect its market areas.

Energy Marketing & Trading. Management believes that EM&T's activities are conducted in substantial compliance with the marketing affiliate rules of FERC Order 497. Order 497 imposes certain nondiscrimination, disclosure, and separation requirements upon interstate natural gas pipelines with respect to their natural gas trading affiliates. EM&T has taken steps to ensure it does not share employees or officers with affiliated interstate natural gas pipelines and does not receive information from affiliated interstate natural gas pipelines that is not also available to unaffiliated natural gas trading companies.

COMPETITION

Exploration & Production. Williams Energy unit competes with a wide variety of independent producers as well as integrated oil and gas companies for markets for its production. E&P has three general phases of operations: acquiring non-producing properties, developing non-producing properties, and operating producing properties. In the process of acquiring minerals, the primary methods of competition are on acquisition price and terms such as duration of the mineral lease, the amount of the royalty payment, and special conditions related to rights to use the surface of the land under which the mineral interest lies. In the process of developing non-producing properties, E&P does not face significant competition. In the operating phase, the primary method of competition involves operating efficiencies related to the cost to produce the hydrocarbons from the reservior.

Midstream Gas & Liquids. Williams Energy competes for gathering and processing business with interstate and intrastate pipelines, producers, and independent gatherers and processors. Numerous factors impact any given customer's choice of a gathering or processing services provider, including rate, term, timeliness of well connections, pressure obligations, and the willingness of the provider to process for either a fee or for liquids taken in-kind. Competition for the natural gas liquids pipelines include other pipelines, tank cars, trucks, barges, local sources of supply (refineries, gasoline plants, and ammonia plants), and other sources of energy such as natural gas, coal, oil, and electricity. Factors that influence customer transportation decisions include rate, location, and timeliness of delivery.

Petroleum Services. Williams Energy's operations are subject to competition because Williams Pipe Line operates without the protection of a federal certificate of public convenience and necessity that might preclude other entrants from providing like service in its area of operations. Further, Williams Pipe Line must plan, operate, and compete without the operating stability inherent in a broad base of contractually obligated or owner-controlled usage. Because Williams Pipe Line is a common carrier, its shippers need only meet the requirements set forth in its published tariffs in order to avail themselves of the transportation services offered by Williams Pipe Line.

Competition exists from other pipelines, refineries, barge traffic, railroads, and tank trucks. Competition is affected by trades of products or crude oil between refineries that have access to the system and by trades among brokers, traders, and others who control products. These trades can result in the diversion from the Williams Pipe Line system of volume that might otherwise be transported on the system. Shorter, lower revenue hauls may also result from these trades. Williams Pipe Line also is exposed to interfuel competition whereby an energy form shipped by a liquids pipeline, such as heating fuel, is replaced by a form not transported by a liquids pipeline, such as electricity or natural gas. While Williams Pipe Line faces competition from a variety of sources throughout its marketing areas, the principal competition is other

11

pipelines. A number of pipeline systems, competing on a broad range of price and service levels, provide transportation service to various areas served by the system. The possible construction of additional competing products or crude oil pipelines, conversions of crude oil or natural gas pipelines to products transportation, changes in refining capacity, refinery closings, changes in the availability of crude oil to refineries located in its marketing area, or conservation and conversion efforts by fuel consumers may adversely affect the volumes available for transportation by Williams Pipe Line.

Williams Energy's ethanol operations compete in local, regional, and national fuel additive markets with one large ethanol producer, numerous smaller ethanol producers, and other fuel additive producers, such as refineries.

The principal competitive forces affecting Williams Energy's refining businesses are feedstock costs, refinery efficiency, refinery product mix, and product distribution. Some of Memphis Refinery's competitors can more easily process sour crudes, and accordingly, are more flexible in the crudes which they can process. Williams Energy has no crude oil reserves and does not engage in crude oil exploration, and it must therefore obtain its crude oil requirements from unaffiliated sources. Williams Energy believes that it will be able to obtain adequate crude oil and other feedstocks at generally competitive prices for the foreseeable future.

The principal competitive factors affecting Williams Energy's retail petroleum business are location, product price and quality, appearance and cleanliness of stores, and brand-name identification. Competition in the convenience store industry is intense. Within the travel center industry, Williams TravelCenters are recognized as leaders in customer service by the local consumer, traveling consumer, and professional driver. Averaging 10,000 square feet, the facilities seamlessly blend these customer groups, resulting in greater revenue and income diversification than traditional convenience stores. Williams Energy intends to construct ten new travel centers in 1999, in addition to six sites currently scheduled to open during the first and second quarters in 1999.

Energy Marketing & Trading. Williams Energy's operations directly compete with large independent energy marketers, marketing affiliates of regulated pipelines and utilities, propane wholesalers and retailers, and natural gas producers. The financial trading business competes with other energy-based companies offering similar services as well as certain brokerage houses. This level of competition contributes to a business environment of constant pricing and margin pressure.

OWNERSHIP OF PROPERTY

The majority of Williams Energy's ownership interests in exploration and production properties are held as working interests in oil and gas leaseholds.

Williams Energy's gathering and processing facilities and natural gas liquids pipelines are owned in fee. Midstream Gas & Liquids constructs and maintains gathering and natural gas liquids pipeline systems pursuant to rights-of-way, easements, permits, licenses, and consents on and across properties owned by others. The compressor stations and gas processing and treating facilities are located in whole or in part on lands owned by subsidiaries of Williams Energy or on sites held under leases or permits issued or approved by public authorities.

Williams Energy owns its petroleum pipeline system in fee. However, a substantial portion of the system is operated, constructed, and maintained pursuant to rights-of-way, easements, permits, licenses, or consents on and across properties owned by others. The terminals, pump stations, and all other facilities of the system are located on lands owned in fee or on lands held under long-term leases, permits, or contracts. The North Pole Refinery is located on land leased from the state of Alaska under a long-term lease scheduled to expire in 2025 and renewable at that time by Williams Energy. The Anchorage, Alaska, terminal is located on land leased from the Alaska Railroad Corporation under two long-term leases. The Memphis Refinery is located on land owned by Williams Energy. Williams Energy owns approximately one-half of the properties upon which its Retail Petroleum stores are located and leases the remainder from third parties. Williams Energy management believes its assets are in such a condition and maintained in such a manner that they are adequate and sufficient for the conduct of business.

12

The primary assets of Williams Energy's energy marketing and trading unit are its term contracts, employees, related systems and technological support, and 180 retail propane outlets located in 18 states including Alabama, Arkansas, Colorado, Florida, Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Mississippi, North Carolina, Ohio, Oklahoma, South Dakota, Tennessee, and Wisconsin.

ENVIRONMENTAL MATTERS

Williams Energy is subject to various federal, state, and local laws and regulations relating to environmental quality control. Management believes that Williams Energy's operations are in substantial compliance with existing environmental legal requirements. Management expects that compliance with existing environmental legal requirements will not have a material adverse effect on the capital expenditures, earnings, and competitive position of Williams Energy. See Note 17 of Notes to Consolidated Financial Statements.

The EPA has named Williams Pipe Line as a potentially responsible party as defined in Section 107(a) of the Comprehensive Environmental Response, Compensation, and Liability Act, for a site in Sioux Falls, South Dakota. The EPA placed this site on the National Priorities List in July 1990. In April 1991 Williams Pipe Line and the EPA executed an administrative consent order under which Williams Pipe Line agreed to conduct a remedial investigation and feasibility study for this site. The EPA issued its "No Action" Record of Decision in 1994, concluding that there were no significant hazards associated with the site subject to two additional years of monitoring for arsenic in certain existing monitoring wells. Williams Pipe Line completed monitoring in the second quarter of 1997 and submitted a report of results to the EPA, which published a Notice of Intent to delete the Sioux Falls site in the January 4, 1999, Federal Register. The public comment period has ended with no significant comments needing to be addressed. Williams Pipe Line expects a closure letter from the EPA in the near future, which will effectively complete the EPA's interest in the site.

Groundwater monitoring and remediation are ongoing at both refineries and air and water pollution control equipment is operating at both refineries to comply with applicable regulations. The Clean Air Act Amendments of 1990 continue to impact Williams Energy's refining businesses through a number of programs and provisions. The provisions include Maximum Achievable Control Technology rules which are being developed for the refining industry, controls on individual chemical substances, new operating permit rules and new fuel specifications to reduce vehicle emissions. The provisions impact other companies in the industry in similar ways and are not expected to adversely impact Williams Energy's competitive position.

WILLIAMS COMMUNICATIONS GROUP, INC.

Williams Communications is comprised of three business units: Network, which owns and operates Williams Communications' fiber optic network; Solutions, which provides customer-premise voice and data equipment, sales, and services including installation, integration, and maintenance; and Applications, which provides video services and other multimedia services for the broadcast industry, advertising distribution, business television applications, audio-, and video-conferencing services for businesses. In Canada, Solutions operates through its subsidiary, WilTel Communications (Canada), Inc. In 1998 Williams Communications sold the product business segment of Williams Learning Network, Inc. and withdrew from the Business Channel partnership. See Note 5 of Notes to Consolidated Financial Statements. Williams Communications also enters into strategic alliances and makes strategic investments in order to secure long-term, high volume customer contracts and gain additional capabilities to better serve its customers.

Williams Communications and its subsidiaries own approximately 19,000-route miles of fiber optic communications network (with an additional 13,000-route miles planned or under construction), maintain 120 offices primarily across North America, but also in London, Singapore, and Australia, and service approximately 100,000 customer sites. In addition, Williams Communications owns four teleports in the United States and has rights to capacity on domestic and international satellite transponders. Williams Communications employed approximately 8,300 employees as of December 31, 1998.

                                                               ========

A business description of each of Williams Communications' business units follows.

NETWORK

The Network unit of Williams Communications, through Williams Communications, Inc., owns and operates approximately 19,000-route miles of fiber optic communications network, 10,000-route miles of which are restricted until July 1, 2001, to multi-media applications including Internet services, and 4,300-route miles of which are not restricted and were acquired from IXC Communications. Network has constructed an unrestricted network along a 1,600 mile route from Houston to Washington, D.C., in proximity to pipeline right-of-way owned by an affiliated company. In addition, Williams Communications, Inc. also owns an interest in a joint venture constructing a 1,600 mile fiber optic network on a route connecting Portland, Salt Lake City, and Las Vegas with a dark fiber agreement extending the network to Los Angeles. "Dark fibers" are optical fibers contained within fiber-optic cables installed along Williams' rights-of-way, which do not have transmission equipment attached. Purchasers of the right to use dark fibers connect their own transmission equipment and transmit their own communications signals over the fibers. Williams Communications, Inc. has also acquired a 350-mile fiber network in Florida and plans to construct additional fiber to connect the Florida network to its existing network in the Southeast and to construct a new fiber route in the midwest region of the United States from Chicago westward. Network has ultimate plans for a 32,000-route mile network.

In January 1998 upon the expiration of the non-compete agreement related to Williams' 1995 sale of its network services operations, Williams Communications announced that it was re-entering the long-distance communications market as a wholesale provider of telecommunications services. Network serves companies that are communications carriers, including long distance telephone companies, local telephone service providers, Internet service providers, and utilities entering the telecommunications market. Network provides these customers with a full range of carrier services, including nationwide transmission of telecommunications signals, Internet transmission services, the origination and termination of a long distance call, local access services, consulting, and operational assistance services.

Customers. Network's customers are primarily other carriers. Network is a carrier to other telecommunications companies, providing dedicated line and switched services to other carriers over its owned or leased fiber optic network facilities. Network's customers currently include regional bell operating companies, Internet service providers, other local service providers, utilities, and competitive local access providers and other providers who desire high speed connectivity to the Internet; asynchronous transfer mode (ATM), which is a switching and transmission technology based on sending various types of information, including voice, data, and video, in packets; or frame relay; private lines; or long distance voice services on a wholesale basis. Sales to Intermedia Communications Inc. accounted for approximately 82.5 percent of Network's revenues in 1998. Sales to the next three largest customers accounted for approximately 13.5 percent of Network's revenues in 1998.

Strategic Alliances. Effective January 1998 Network entered into an agreement with US West, which provides that the two companies will work together to provide data networking services and vertical applications to a variety of customers. US West has agreed to use Network on a preferred provider basis

14

through 2002 and is required to purchase at least $36.6 million of services and equipment from Network over the five-year term.

Network also entered into an agreement with Concentric Network Corporation to provide wholesale communications services. Williams Communications owns approximately 16 percent of Concentric. Under the agreement with Concentric, Concentric has agreed to purchase either services or equipment from Network or Solutions, respectively, valued at a minimum of $21 million over the five-year contract term. Concentric has also agreed that Network or Solutions, respectively, will be its preferred provider for these services and equipment.

In April 1998 Intermedia Communications Inc. purchased a 20-year indefeasible right of use for Network's nationwide transmission capacity with a value of approximately $450 million. An indefeasible right of use is an exclusive, indefeasible right to use the specified property for a term essentially representing the economic life of the property. The $450 million represents the present value of the minimum amount Intermedia will pay over the life of the agreement. Network will provide Intermedia with transmission capacity at rates up to 9.952 billion bits per second.

In October 1998 Network purchased shares of preferred stock of UniDial Communications, Inc. for a purchase price of $27 million. Dividends begin to accrue at the rate of ten percent per annum beginning October 1, 1999. The shares are convertible into shares of common stock under certain circumstances, with Network's resulting percentage of UniDial being subject to various formulas and timing elements. UniDial markets a variety of long distance and other communications products including frame relay, Internet, and conferencing services. UniDial has agreed to use Network as a preferred provider and has also agreed to allow Solutions to sell UniDial's products and services at competitive prices and for UniDial to handle the billing and collection relating to Solution's sales of their services.

On December 17, 1998, Network entered into two agreements with WinStar Wireless, Inc., a provider of communications services that uses wireless technology to provide high capacity local exchange and Internet access services to companies located in buildings not served by fiber optic cable. The agreements give Network a 25-year right to use approximately two percent of WinStar's wireless capacity in exchange for installment payments totaling $400 million over approximately two years, and give WinStar a 25-year right to use four strands of Network's fiber over 15,000-route miles in exchange for a seven year $476 million obligation.

In February 1999 Network entered into a strategic alliance with SBC Communications under which Network will be SBC's preferred provider for domestic voice and data long distance services for 20 years, SBC will be Network's preferred provider for selected international wholesale services, toll-free operator, calling card, and directory assistance services for 20 years, Solutions will sell SBC's products to its customers, and SBC may sell Network's services to its customers. Additionally, SBC agreed to make an equity investment by purchasing the lesser of $500 million or ten percent of the common stock of Williams Communications at the time of the initial public offering.

SOLUTIONS

The Solutions unit of Williams Communications, operated primarily through Williams Communications Solutions, LLC (WCS), provides services and sells and installs equipment for the voice, video, and data networks of its customers. WCS was formed in April 1997 following the merger of subsidiaries of Williams Communications and Northern Telecom, Inc. Williams Communications now holds a 70 percent interest in WCS, and Northern Telecom owns the remaining 30 percent. Williams Communications continues to address challenges following the combination related to integration of software systems, related processes, and business issues.

Williams Communications, through subsidiaries including WCS, serves customers at approximately 100,000 business locations throughout the United States consisting of small, medium, and large businesses and governmental, educational, and non-profit institutions. Solutions' customer base ranges from large, publicly-held corporations and the federal government to small, privately-owned entities. Solutions' top 25 customers

15

combined accounted for approximately 12 percent of its revenue in 1998. Solutions' employs approximately 6,400 employees, including sales employees, billable engineers, design specialists, and service technicians.

Solutions also helps its customers reduce the complexity and cost of their communications decisions by combining components from a variety of manufacturers into the communications solutions required by its customers. Solutions' broad range of voice, video, and data solutions allow Solutions to serve as a single-source provider for its customers' communications needs. Solutions distributes the products and services of a number of leading communications suppliers including Nortel, SBC Communications, Cisco Systems, Lucent Technologies, NEC, US West, and Bell Atlantic. Solutions also provides service and maintenance support for these products.

Operating Statistics. The following table summarizes the results of operations for the Solutions unit of Williams Communications for the periods indicated (dollars in millions):

Segment profit (loss)..................................   $  (54.1)  $   47.3   $ 14.3

In 1998 Solutions derived approximately 56 percent of its revenues from its existing customer base through system modifications and maintenance and approximately 43 percent from the sale of new telecommunications systems to its existing customer base and new customers. Solutions' three largest suppliers accounted for approximately 91 percent of equipment sold in 1998. A single manufacturer, Northern Telecom, supplied approximately 83 percent of all equipment sold. In this case, WCS is the largest independent distributor in the United States of certain of this company's products. The distribution agreement with this supplier is scheduled to expire at the end of 2000. Management believes there is minimal risk as to the availability of products from suppliers.

APPLICATIONS

Vyvx

Vyvx, an unincorporated business unit of Williams Communications, Inc., offers broadcast-quality television and multimedia transmission services nationwide by means of Network's 19,000-mile multimedia network, four satellite teleport facilities located near Atlanta, Denver, Los Angeles, and New York, and satellite transponders capacity. Vyvx primarily provides backhaul or point-to-point transmission of sports, news, and other programming between two or more customer locations. With satellite facilities, Vyvx provides point-to-multipoint transmission service. Vyvx's customers include all of the major broadcast and cable networks. Vyvx is also engaged in the business of advertising distribution and is exploring other multimedia communication opportunities.

Conferencing

Global Access, offers multi-point videoconferencing and audio-conferencing, as well as single point to multi-point business television services. Global Access enables Williams Communications to provide customers with integrated media conferences, bringing together voice and video by utilizing Williams Communications' existing fiber-optic and satellite services.

In 1998 Williams Communications withdrew from The Business Channel, a joint venture with the Public Broadcast Services (PBS). See Note 5 of Notes to Consolidated Financial Statements.

REGULATORY MATTERS

Network. Williams Communications, Inc. is subject to Federal Communications Commission regulations as a common carrier with regard to certain of its transmission services and is subject to the laws of certain states governing public utilities. An FCC rulemaking to eliminate domestic, common carrier tariffs has been stayed pending judicial review. In the interim, the FCC is requiring such carriers to operate under traditional tariff rules. Operations of intrastate microwave communications, satellite earth stations, and certain other related transmission facilities are also subject to FCC licensing and other regulations. These regulations do not significantly impact Williams Communications, Inc.'s operations. In 1997 the FCC began implementation of the Universal Service Fund contemplated in the Telecommunications Act of 1996. Williams Communications, Inc. is required to contribute to this fund based upon certain revenues. Although Williams Communications, Inc. intends to pass on such charges to its customers, FCC rulings raise questions about the right of companies like Williams Communications, Inc. to do so.

Solutions. The equipment WCS sells must meet the requirements of Part 68 of the FCC rules governing the equipment registration, labeling and connection of equipment to telephone networks. WCS relies on the equipment manufacturers' compliance with these requirements for its own compliance regarding the equipment it distributes. These regulations have a minimal impact on WCS' operations.

COMPETITION

Network. In the market for network transmission services, Williams Communications faces competition from three major facilities-based long distance fiber optic network companies. In addition, several other companies have just completed or are in the process of constructing regional and nationwide fiber optic networks that will compete with Williams Communications in the wholesale network market. Because Williams Communications has focused its efforts on the market for wholesale network services, it does not compete with these networks in the retail sector of the market. Network intends to compete by being the lowest cost provider in the market for technologically advanced network services and by pursuing only wholesale opportunities. By avoiding the retail market, it seeks to avoid the situation of competing with its customers who purchase wholesale services for resale in the retail market.

Federal telecommunications reform legislation enacted in February 1996 is designed to increase competition both in the long distance market and local exchange market by significantly liberalizing current restrictions on market entry. In particular, the legislation establishes procedures permitting Regional Bell Operating Companies to provide long distance services including, but not limited to, video transmission services, subject to certain restrictions and conditions precedent. Moreover, electric and gas utilities may provide telecommunications services, including long distance services, through separate subsidiaries. The legislation also calls for elimination of federal tariff filing requirements and relaxation of regulation over common carriers. At this time, management cannot predict the impact such legislation may have on Networks' operations.

The Regional Bell Operating companies continue to seek regulatory approval to provide national long distance services. As courts or regulators remove restrictions on the Regional Bell Operating Companies, they will be both important potential customers and important potential competitors of Network. If Regional Bell Operating Companies are permitted to compete in the market for long-distance services, they will require nationwide fiber networks to provide services. If any such Regional Bell Operating Company chooses to contract with Williams Communications for use of its network, it could create opportunities for Williams Communications to sell fiber or to lease long distance, high volume capacity. If any such Regional Bell Operating Company chooses either to construct its own network or to contract with one of Williams Communications' competitors, it would be in a position to provide nationwide long distance services in direct competition with Williams Communications.

Solutions. For the Solutions business, Williams Communications is the largest independent provider of integrated communications solutions to businesses throughout North America. Though 30 percent owned by Northern Telecom, Solutions maintains strong relationships with other manufacturers of products that it sells to its customers. Solutions' competitors include communications equipment distributors, network integrators,

17

and manufacturers of equipment (including in some instances those manufacturers whose products Solutions also sells). WCS has many competitors ranging from Lucent Technologies, Siemens, and Cisco Systems to small individually-owned companies that sell and service customer-premise equipment. Because WCS sells and installs equipment manufactured by third parties and provides maintenance services on the equipment it sells, it seeks to compete by giving customers their choice of high quality, technologically advanced equipment along with high quality service.

Applications. Vyvx's video and multimedia transmission operations compete primarily with companies offering video or multimedia transmission services by means of satellite facilities and to a lesser degree with companies offering transmission services via microwave facilities or fiber-optic cable. Vyvx competes by providing high quality services in its niche market.

OWNERSHIP OF PROPERTY

Network. Williams Communications owns part of the fiber-optic transmission facilities and leases the remainder. Approximately 10,000-route miles of its owned facilities are comprised of a single fiber, which is on a portion of the fiber optic network of MCI WorldCom, Inc. and is restricted until July 1, 2001, to multimedia content usage. Williams Communications retained this fiber when a predecessor of MCI WorldCom purchased Williams Communications' network services operations in 1995. Williams Communications carries signals by means of its own fiber-optics facilities, as well as carrying signals over fiber-optic facilities leased from third-party interexchange carriers and the various local exchange carriers. Williams Communications holds its satellite transponder capacity under various agreements. Williams Communications owns part of its teleport facilities and holds the remainder under either a management agreement or long-term facilities leases.

Network intends to obtain capacity primarily by means of the fiber optic networks Williams Communications is constructing or plans to construct or acquire, as well as acquiring dark fiber rights on fiber optic facilities of other carriers. Network obtains dark fiber rights in the form of the purchase or lease of "indefeasible rights of use" or "IRUs" in specific fiber strands. Purchased IRUs have many of the characteristics of ownership, including many of the associated risks, but the owner of the fiber optic cable retains legal title to the fibers. Specifically, an IRU is an exclusive, indefeasible right to use the specified property for a term essentially representing the economic life of the property. The grant of an IRU transfers the risks and rewards of ownership but does not convey title, ownership, or rights of possession in the network, the individual fibers comprising the network, the related right-of-way agreements, or any other real or personal property. The transferee of an IRU typically has a right to retake possession at the end of the contract term, which generally exceeds 20 years.

ENVIRONMENTAL MATTERS

Williams Communications is subject to federal, state, and local laws and regulations relating to the environmental aspects of its business. Management believes that Williams Communications' operations are in substantial compliance with existing environmental legal requirements. Management expects that compliance with such existing environmental legal requirements will not have a material adverse effect on the capital expenditures, earnings, and competitive position of Williams Communications.

WILLIAMS INTERNATIONAL COMPANY

Williams International Company, through subsidiaries, has made direct investments in energy and telecommunications projects primarily in South America and Australia and continues to explore and develop additional projects for international investment. Williams International also has investments in energy, telecommunications, and infrastructure development funds in Asia and Latin America.

El Furrial. Williams International owns a 67 percent interest in a venture near the El Furrial field in eastern Venezuela that constructs, owns, and operates medium and high pressure gas compression facilities for Petroleos de Venezuela (PDVSA), the state owned petroleum corporation of Venezuela.

18

The medium pressure facility compresses 130 MMcf per day of raw natural gas from 100 to 1,200 p.s.i.g. for delivery into a natural gas processing plant owned by PDVSA. The high pressure facility compresses 450 MMcf per day of processed natural gas from 1,100 to 7,500 p.s.i.g. for injection into PDVSA's El Furrial producing field.

The medium pressure facility began operations in November 1997. The high pressure facility began operations in September 1998. An expansion of the high pressure facility to 650 MMcf per day is underway, and Williams International anticipates that the expansion will be complete in the second half of 1999.

Jose Terminal. In November 1998 a consortium in which Williams International owns 45 percent, entered into an agreement with PDVSA to purchase the Jose Terminal, an 800,000 Bbp per day petroleum storage and shiploading facility in northeastern Venezuela, for a 20-year renewable term. As part of the transaction, PDVSA, directly and indirectly through its partners, has committed to store and shipload an average of 873,000 Bbp per day of crude oil during the first 20 years of the transaction. The interim operations began in the first quarter of 1999, and formal closing is expected in the second quarter of 1999.

Apco Argentina. Williams International also owns an interest in Apco Argentina Inc., an oil and gas exploration and production company with operations in Argentina. Apco Argentina's principal business is its 47.6 percent interest in the Entre Lomas concession in southwest Argentina. It also owns a 45 percent interest in the Canadon Ramirez concession and a 1.5 percent interest in the Acambuco concession.

At December 31, 1998, 1997, and 1996, estimated developed, proved reserves net to Apco Argentina were 15.5, 23.7, and 24.2 million barrels, respectively, of oil, condensate, and plant products, and 26.8, 35.8, and 44.3 Bcf, respectively, of natural gas. Estimated undeveloped, proved reserves net to Apco Argentina were 5.1, 9.5, and 10.5 million barrels, respectively, of oil, condensate, and plant products, and 700 MMcf, 800 MMcf, and 2.5 Bcf, respectively, of natural gas.

At December 31, 1998, the gross and net developed concession acres owned by Apco Argentina totaled 37,140 acres and 17,093 acres, respectively, and the gross and net undeveloped concession acres owned were 504,860 acres and 115,493 acres, respectively. At December 31, 1998, Apco Argentina owned interests in 452 gross producing wells and 212 net producing wells on its concession acreage.

Total net production sold during 1998, 1997, and 1996 was 1.7, 1.8, and 1.6 million barrels, respectively, of oil, condensate, and plant products, and 7.7, 7.7, and 8.4 Bcf, respectively, of natural gas. The average production costs, including all costs of operations such as remedial well workovers and depreciation of property and equipment, per barrel of oil produced were $9.09, $8.27, and $8.15, respectively, and per Mcf of natural gas produced were $.23, $.21, and $.22, respectively. The average wellhead sales price per barrel of oil sold were $12.71, $19.52, and $20.87, respectively, and per Mcf of natural gas sold were $1.33, $1.34, and $1.33, respectively, for the same periods.

Lightel and Brazilian Cellular Project. Williams International owns a 20 percent equity interest in Lightel, S.A., a company that owns interests in a local exchange carrier, a cable television company, and cellular telephone companies in Brazil. In April 1998 Williams International participated in Lightel's acquisition of licenses to provide cellular telephone service in the States of Sao Paulo, Rio de Janeiro, and Espirito Santo by issuing convertible debt to Lightel to help fund the investment and by directly investing in ATL -- Algar Telecom Leste, S.A. which holds the Rio de Janeiro and Espirito Santo concession in exchange for a 30 percent equity ownership interest in ATL. Construction on the cellular network began in 1998 and is expected to be complete in the first quarter of 1999. In February 1999 Williams International exercised its right of first refusal to acquire an additional 35 percent equity interest in ATL. It anticipates completing the transaction before the end of the first quarter of 1999.

PowerTel. In August 1998 Williams International closed a transaction under which it will eventually own an approximate 45 percent direct and 2.4 percent indirect interest in PowerTel Limited (a publicly traded corporation in which three Australian electric utilities will own a 30 percent interest) to build, own, and operate a fiber optic telecommunications network in Australia serving the cities of Brisbane, Sydney, and Melbourne, as well as other cities. Engineering and construction work on the network began in the fourth quarter of 1998, and commercial operations are expected to commence midyear 1999.

19

MetroCom. In March 1999 Williams International plans to acquire a 19.9 percent equity interest in Metrocom, S.A., a Chilean company formed by Metrogas, S.A., to build, own, and operate a telecommunications network providing high-quality, low-cost local, Internet, data, and voice services to businesses and residences in the Santiago metropolitan area, focusing on the commercial and high-end residential markets. Metrogas, S.A., whose shareholders consist of several large international and Chilean electric utilities and energy companies, is installing a natural gas distribution network in Santiago along with telecommunications ducts for the installation of the fiber optic network. The estimated cost of the investment is approximately U.S. $24.5 million.

OTHER INFORMATION

Williams Holdings believes that it has adequate sources and availability of raw materials to assure the continued supply of its services and products for existing and anticipated business needs. At December 31, 1998, Williams Holdings had approximately 17,450 full-time employees, of whom approximately 1,312 were represented by unions and covered by collective bargaining agreements. In September 1998 Williams created three new companies in order to streamline payroll processing and reduce costs. In connection with this, Williams transferred its employees to one of these companies, and the employees are now jointly employed by Williams and one of these new companies. This change had no impact on Williams' management structure or on its employees' seniority and benefits. Williams considers its relations with its employees to be generally good.

ITEM 2. PROPERTIES

See Item 1(c) for description of properties.

ITEM 3. LEGAL PROCEEDINGS

For information regarding certain proceedings pending before federal regulatory agencies, see Note 17 of Notes to Consolidated Financial Statements. Williams Holdings is also subject to other ordinary routine litigation incidental to its businesses.

Environmental matters

Certain Williams Holdings' subsidiaries have been identified as potentially responsible parties (PRP) at various Superfund and state waste disposal sites. In addition, these subsidiaries have incurred, or are alleged to have incurred, various other hazardous materials removal or remediation obligations under environmental laws. Although no assurances can be given, Williams Holdings does not believe that the PRP status of these subsidiaries will have a material adverse effect on its financial position, results of operations or net cash flows.

The Midstream Gas & Liquids unit of Williams Energy had recorded an aggregate liability of approximately $10 million, representing the current estimate of future environmental and remediation costs. Williams Energy also accrues environmental remediation costs for its petroleum products pipelines, retail petroleum, refining, and propane marketing operations primarily related to soil and groundwater contamination. At December 31, 1998, Williams Energy and its subsidiaries had reserves, in addition to the reserves listed above, totaling approximately $31 million. Williams Energy recognizes receivables related to environmental remediation costs from state funds as a result of laws permitting states to reimburse certain expenses associated with underground storage tank problems and repairs. At December 31, 1998, Williams Energy and its subsidiaries had receivables totaling $14 million. Actual costs incurred will depend on the actual number of

21

contaminated sites identified, the actual amount and extent of contamination discovered, the final cleanup standards mandated by the EPA and other governmental authorities and other factors.

Other legal matters

On April 7, 1992, a liquefied petroleum gas explosion occurred near an underground salt dome storage facility located near Brenham, Texas, and owned by an affiliate of MAPCO Inc., Seminole Pipeline Company. MAPCO Inc., as well as Seminole, Mid-America Pipeline Company, MAPCO Natural Gas Liquids Inc., and other non-MAPCO entities were named as defendants in civil action lawsuits filed in state district courts located in four Texas counties. Seminole and the above-mentioned subsidiaries of MAPCO Inc. have settled in excess of 1,600 claims in these lawsuits. The only lawsuit remaining is the Dallmeyer case which was tried before a jury in Harris County, Texas. In Dallmeyer, the judgment rendered in March 1996 against defendants Seminole and MAPCO Inc. and its subsidiaries totaled approximately $72 million, which included nearly $65 million of punitive damages awarded to the 21 plaintiffs. Both plaintiffs and defendants have appealed the Dallmeyer judgment to the Court of Appeals for the Fourteenth District of Texas in Harris County. The defendants seek to have the judgment modified in many respects, including the elimination of punitive damages as well as a portion of the actual damages awarded. If the defendants prevail on appeal, it will result in an award significantly less than the judgment. The plaintiffs have cross-appealed and seek to modify the judgment to increase the total award plus interest to exceed $155 million. In February and March 1998, the defendants entered into settlement agreements involving 17 of the 21 plaintiffs to finally resolve their claims against all defendants for an aggregate payment of approximately $10 million. These settlements have satisfied and reduced the judgment on appeal by approximately $42 million. As to the remaining four plaintiffs, the Court of Appeals issued its decision on October 15, 1998, which, while denying all of the plaintiffs' cross-appeal issues, affirmed in part and reversed in part the trial court's judgment. The defendants had entered into settlement agreements with the remaining plaintiffs which, in light of the decision, Williams believes will provide for aggregate payments of approximately $13.6 million, the full amount of which has been previously accrued.

In 1991 the Southern Ute Indian Tribe filed a lawsuit against Williams Production Company, a wholly owned subsidiary of Williams, and other gas producers in the San Juan Basin area, alleging that certain coal strata were reserved by the United States for the benefit of the Tribe and that the extraction of coal-seam gas from the coal strata was wrongful. The Tribe sought compensation for the value of the coal-seam gas. The Tribe also sought an order transferring to the Tribe ownership of all of the defendants' equipment and facilities utilized in the extraction of the coal-seam gas. In September 1994 the court granted summary judgment in favor of the defendants and the Tribe lodged an interlocutory appeal with the U.S. Court of Appeals for the Tenth Circuit. Williams Production agreed to indemnify the Williams Coal Seam Gas Royalty Trust against any losses that may arise in respect of certain properties subject to the lawsuit. On July 16, 1997, the Court of Appeals reversed the decision of the District Court, held that the Tribe owns the coal-seam gas produced from certain coal strata on fee lands within the exterior boundaries of the Tribe's reservation, and remanded the case to the District Court for further proceedings. On September 16, 1997, Amoco Production Company, the class representative for the defendant class (of which Williams Production is a part), filed its motion for rehearing en banc before the Court of Appeals. On July 20, 1998, the Court of Appeals sitting en banc affirmed the panel's decision. The U.S. Supreme Court has granted a writ of certiorari in respect of this decision.

In late March 1999 Williams Production, BP Amoco, and the Tribe announced that they are in settlement negotiations to finalize the terms of an agreement in connection with the claims asserted against Williams. Under the proposed settlement, Williams Production will convert its net profits interest in the production from the oil and gas leases in dispute into a working interest. A portion of Williams Production's working interest will then be transferred to the Tribe effective January 1, 1999. The Tribe will release Williams Production from all other claims asserted in the lawsuit. This pending settlement agreement does not address key issues still being pursued on appeal to the Supreme Court, including the ownership of the natural gas in the coal formation, tribal severance tax payments, and other matters. The Supreme Court is expected to render its decision by mid-1999. The details of this settlement are still being negotiated, and it must be

22

approved by the District Court after an opportunity for review and comment. Williams believes the parties will be successful in reaching a final agreement on the partial settlement in principal and that it will be approved by the District Court.

In 1998 the United States Department of Justice informed Williams that Jack Grynberg, an individual, had filed claims in the United States District Court for the District of Colorado under the False Claims Act against Williams and certain of its wholly owned subsidiaries including Williams Field Services Company and Williams Production Company. Mr. Grynberg has also filed claims against approximately 300 other energy companies and alleges that the defendants violated the False Claims Act in connection with the measurement and purchase of hydrocarbons. The relief sought is an unspecified amount of royalties allegedly not paid to the federal government, treble damages, civil penalty, attorneys' fees, and costs.

In addition to the foregoing, various other proceedings are pending against Williams or its subsidiaries which are incidental to their operations.

Summary

While no assurances may be given, Williams Holdings does not believe that the ultimate resolution of the foregoing matters, taken as a whole and after consideration of amounts accrued, insurance coverage, recovery from customers, or other indemnification arrangements, will have a materially adverse effect upon Williams Holdings' future financial position, results of operations, or cash flow requirements.

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

RESULTS OF OPERATIONS

1998 vs. 1997

CONSOLIDATED OVERVIEW. Williams Holdings' revenues decreased $578 million, or 9 percent, due primarily to the $384 million impact in 1998 of reporting certain revenues net of costs within Energy Services (see Note 1 of Notes to Consolidated Financial Statements) and lower petroleum products and natural gas liquids sales prices. Favorably effecting revenues were higher revenues from Communications' equipment sales and services activities and excess fiber sales, higher power services revenues and increased petroleum products sales volumes.

Segment costs and expenses decreased $258 million, or 4 percent, due primarily to the $384 million impact in 1998 of reporting certain costs net in revenues within Energy Services (see Note 1) and lower purchase prices for petroleum products. Partially offsetting these decreases were higher costs and expenses within Communications, costs associated with increased petroleum products sales volumes, higher power services costs and $77 million of higher charges in 1998 as compared to 1997. The 1998 charges include $37 million of asset impairments, $51 million of MAPCO merger-related expenses, a $16 million accrual for potential transportation rate refunds and a $23 million accrual for modification of an employee benefit program associated with vesting of paid time off. Included in 1997 are charges totaling $50 million for asset impairments.

Operating income decreased $308 million, or 70 percent, reflecting the change in revenues and segment costs and expenses discussed above and comprised primarily of a $176 million decrease at Energy Services and a $117 million decrease at Communications. Income from continuing operations before extraordinary loss and income taxes decreased $451 million, or 99 percent, due primarily to the lower operating income, $43 million higher interest expense resulting from continued expansion and new projects, the effect of a $45 million gain in 1997 on the sale of interest in subsidiary and the effect of a $66 million gain in 1997 on the sale of assets.

ENERGY MARKETING & TRADING'S revenues decreased $337.7 million, or 15 percent, due primarily to the $384 million impact in 1998 of reporting revenues on a net basis for certain natural gas liquids trading operations previously reported on a "gross" basis (see Note 1) and $95 million lower crude and refined products marketing and trading revenues. In addition, revenues associated with natural gas origination, price-risk management and physical trading decreased $50 million reflecting lower margins, the unfavorable market movement against the natural gas portfolio and the adverse market and supply conditions which resulted from Hurricane Georges in September 1998, partially offset by the $24 million favorable effect of certain contract settlements and terminations. Retail propane revenues decreased $59 million due to the $35 million effect of lower volumes following unseasonably warm weather in 1998 as compared to 1997 and the $24 million effect of lower average propane sales prices. Partially offsetting these decreases were $243 million higher power services revenues including $220 million from new power activity in southern California and additional business growth.

Costs and operating expenses decreased $407 million, or 19 percent, due primarily to the $384 million impact in 1998 of reporting revenues on a net basis for certain natural gas liquids trading operations previously reported on a "gross" basis (see Note 1) and $104 million lower product purchases associated with the marketing and trading of crude and refined products. In addition, retail propane cost of sales decreased $55 million due to the $21 million effect of lower volumes and the $34 million effect of lower average propane purchase costs. These decreases were partially offset by $156 million of costs related to new power activity in southern California.

Segment profit decreased $14.4 million, or 27 percent, due primarily to the $50 million decline in revenues from natural gas trading activities discussed above, $43 million of additional losses from retail natural gas and electric activities and the effect of a $6 million recovery in 1997 of an account previously written off as a bad debt. The $43 million of losses from retail natural gas and electric activities includes $17 million of credit losses and $14 million of asset impairments (included in other (income) expense -- net). The $14 million asset impairment is associated with the company's decision to change focus from selling to small

F-2

commercial and residential customers to large end users (see Note 5). The retail natural gas and electric losses also reflect costs incurred to penetrate new markets. Offsetting these decreases were $60 million of higher electric power marketing and trading profits, $17 million lower retail propane operating expenses and $7 million higher natural gas liquids trading profits.

EXPLORATION & PRODUCTION'S revenues increased $9.2 million, or 7 percent, due primarily to the recognition of $22 million of additional deferred income resulting from a 1997 transaction that transferred certain nonoperating economic benefits to a third party and $8 million from a 14 percent increase in company- owned production, partially offset by the $25 million effect of lower average natural gas sales prices for company-owned production and for sales of volumes from the Williams Coal Seam Gas Royalty Trust (Royalty Trust) and royalty interest owners.

Segment profit decreased $3.1 million, or 10 percent, due primarily to $13 million higher depreciation, depletion and amortization, $6 million higher nonproducing leasehold amortization, $2 million higher dry hole costs and $2 million of leasehold impairment costs, partially offset by the $22 million increased recognition of deferred income.

MIDSTREAM GAS & LIQUIDS' revenues decreased $143.8 million, or 15 percent, due primarily to $60 million lower natural gas liquids sales from processing activities reflecting a decline in average liquids sales prices, and the $44 million effect of the shutdown of the Canadian liquids marketing operations in late 1997. Revenues also declined due to $18 million lower natural gas liquids pipeline transportation revenues reflecting 3 percent lower shipments, the passthrough of $9 million lower operating costs to customers and the effect of an $8 million receipt in 1997 of business interruption insurance proceeds, slightly offset by $9 million higher gathering revenues and $8 million associated with a 4 percent increase in natural gas liquids sales volumes.

Costs and operating expenses decreased $88 million, or 15 percent, due primarily to the $50 million effect of the shutdown of the Canadian liquids marketing operations, $9 million lower costs passed through to customers, $15 million lower fuel and replacement gas purchases, and lower natural gas liquids pipeline transportation costs.

Other (income) expense -- net in 1998 includes a loss of approximately $9 million related to the retirement of certain assets and $6 million of unfavorable litigation loss provisions, partially offset by a $6 million gain from the settlement of product imbalances.

Segment profit decreased $60.2 million, or 22 percent, due primarily to $45 million of lower per-unit liquids margins, decreased pipeline transportation shipments, the $9 million loss related to the retirement of certain assets and the effect of an $8 million business interruption insurance receipt in 1997, slightly offset by $9 million higher gathering revenues.

PETROLEUM SERVICES' revenues decreased $20.5 million, or 1 percent, due primarily to a $213 million decrease in revenues from refining operations and $17 million lower product sales from transportation activities, significantly offset by $107 million higher pipeline construction revenue, $54 million higher convenience store sales, and $37 million higher revenues from fleet management and mobile computer technology operations initiated in mid-1997. The $213 million decline in refining revenues reflects $386 million from lower average sales prices, partially offset by $173 million from a 13 percent increase in refined product volumes sold. The $54 million increase in convenience store sales is due primarily to the May 1997 EZ-Serve acquisition, additional travel centers and increased per-store merchandise sales. Increases of $101 million in gasoline and diesel sales volumes and $47 million higher merchandise sales were partially offset by a $94 million impact of lower average retail gasoline and diesel sales prices.

Costs and expenses increased $27 million, or 1 percent, due primarily to $102 million of pipeline construction costs, $46 million higher convenience store merchandise purchases and operating costs resulting from the EZ-Serve acquisition, additional travel centers and increased per-store sales, $41 million higher costs from fleet management and mobile computer technology operations, $24 million higher general and administrative expenses and a $15.5 million accrual for potential transportation rate refunds to customers (included in other (income) expense -- net) (see Note 17). Substantially offsetting these increases were a $194 million decrease from refining operations and $15 million lower cost of product sales from transportation

F-3

activities. The $24 million increase in general and administrative expenses is due, in part, to increased activities in human resources development, investor/media/customer relations and business development. The $194 million decrease from refining operations reflects a $343 million decrease due to lower average crude oil purchase prices, partially offset by a $143 million increase related to an increase in processed barrels sold and $7 million higher operating costs at the Memphis refinery. Convenience store gasoline and diesel cost of sales remained flat as a $90 million increase from higher sales volumes was offset by lower average purchase prices.

Segment profit decreased $47.5 million, or 24 percent, due primarily to the $15.5 million accrual for potential refunds to transportation customers, $13 million lower refinery gross margins, $7 million higher operating costs due to increased production levels at the Memphis refinery, approximately $24 million higher general and administrative expenses and a $4.4 million accrual for modification of an employee benefit program associated with vesting of paid time off, partially offset by $6 million higher product transportation revenues, $7 million increased profits from convenience store operations and $5 million from pipeline construction activities.

COMMUNICATIONS SOLUTIONS' revenues increased $160.3 million, or 13 percent, due primarily to the April 30, 1997, combination of the Nortel customer premise equipment sales and services operations, which contributed an additional $196 million of revenue during the first four months of 1998. A $30 million increase in maintenance contract revenues was more than offset by $46 million lower new system sales and $31 million lower customer service orders due, in part, to competitive pressures.

Costs and operating expenses increased $116 million, or 13 percent, and selling, general and administrative expenses increased $138 million, or 53 percent, due primarily to the combination with Nortel. Included in the overall increase in selling, general and administrative expenses are $23 million of increased information systems costs associated with expansion and enhancement of the infrastructure and continued costs of maintaining multiple systems while common systems are being developed, $36 million higher selling costs including the effects of large increases in sales and support staff and higher sales commissions in anticipation of a higher revenue base than actually achieved, $12 million increased provision for bad debts, and a $6 million accrual for modification of an employee benefit program associated with vesting of paid time off.

Segment profit decreased $101.4 million from a $47.3 million segment profit in 1997 to a $54.1 million segment loss in 1998, due primarily to the increase in selling, general and administrative costs as described above, $6 million related to information systems cancellations and $7 million of obsolete equipment write-downs, severance and contract loss accruals.

NETWORK APPLICATIONS' revenues decreased $9.1 million, or 4 percent, due primarily to the $14 million effect of the decision to exit the learning content business in November 1997. Partially offsetting this decline was a $9 million increase in audio and video conferencing and business television revenues.

Costs and operating expenses increased $9 million, or 5 percent, due primarily to $8 million higher costs of providing network services following the transfer of fiber assets to Network Services in October 1997 and the $7 million effect of increased audio and video conferencing and business television activities, partially offset by $8 million lower costs as a result of the decision to exit the learning content business in November 1997. A $10 million, or 11 percent, decrease in selling, general and administrative expenses was also due to the decision to exit the learning content business.

Other (income) expense -- net in 1998 includes a $23.2 million write-down related to the abandonment of a venture involved in the technology and transmission of business information for news and educational purposes (see Note
5). Other (income) expense -- net in 1997 includes charges totaling $49.8 million related to the decision and formulation of a plan to sell the learning content business ($28 million), and the write-down of assets and development costs associated with certain advanced applications (see Note 5). During 1998, a substantial portion of the learning content business was sold at its approximate carrying value.

Segment loss decreased $14.1 million from a $108.7 million segment loss in 1997 to a $94.6 million segment loss in 1998, due primarily to the effect of $49.8 million of charges in 1997, partially offset by the $23.2 million write-down in 1998, $7 million higher network access costs and a $3 million accrual for modification of an employee benefit program associated with vesting of paid time off.

F-4

NETWORK SERVICES' revenues increased $151.9 million from $43 million in 1997, due primarily to $64 million of revenue in 1998 from the sale of excess fiber capacity on the newly constructed digital fiber-optic network, $49 million of revenues from providing fiber services to new long-term customers and $27 million higher revenue following the transfer of fiber assets from Network Applications in October 1997.

Costs and operating expenses increased $136 million from $32 million in 1997, due primarily to $38 million of cost of sales of excess fiber capacity, $55 million of leased capacity costs associated with providing customer services prior to completion of the new network, and $17 million higher operating expenses. Selling, general and administrative expenses increased $45 million due primarily to the expansion of the infrastructure to support the new national digital fiber-optic network, including $8 million of increased information systems costs and $8 million for a new national advertising campaign.

Segment profit decreased $29.6 million from a $3.3 million segment profit in 1997 to a $26.3 million segment loss in 1998, due primarily to the cost of expanding the infrastructure in support of the network expansion and losses experienced from providing customer services prior to completion of the new network, partially offset by $26 million of profit from selling excess fiber capacity.

As each phase of the ongoing construction of the planned 32,000 mile full-service wholesale communications network goes into service, revenues and costs are expected to increase. During 1998, 9,000 miles of new network were added increasing the network to 19,000 cable miles at December 31, 1998. The remaining 13,000 miles are planned to come online during 1999 and 2000. This business is expected to contribute an increasing percentage of consolidated revenues but is not expected to contribute significantly to segment profit until 2001. The February 8, 1999, announcement by Williams of a 20-year agreement with SBC Communications, under which Network Services will become the preferred provider of nationwide long-distance voice and data services for SBC Communications, will contribute to the expected network revenue increase in 2000. Additional sales of excess dark fiber capacity along the new network are expected to generate increasing revenues and segment profit during 1999 and 2000.

OTHER segment loss of $14.5 million in 1998 compares to $12.7 million of segment profit in 1997. The 1998 segment loss includes equity losses of $14.8 million from investing activities in a Brazilian communication business in which Williams has a 30 percent interest. This business is constructing a cellular phone network scheduled to be in operation during 1999. In addition, 1998 includes $8 million higher general and administrative expenses as compared to 1997 and $5.6 million of write-downs of international cost investments to market.

GENERAL CORPORATE EXPENSES decreased $11.6 million, or 16 percent, due primarily to expense savings realized following the MAPCO merger, largely offset by MAPCO merger-related costs of $21 million in 1998 compared to $10 million in 1997. An additional $51 million of merger-related costs are included as a component of Energy Services' segment profit (see Note 19). Interest accrued increased $49.8 million, or 38 percent, due primarily to higher borrowing levels including Williams Holdings' commercial paper program and advances from affiliates, partially offset by the $9 million effect of a lower average interest rate. Interest capitalized increased $7.3 million, or 38 percent, due primarily to increased capital expenditures for the fiber-optic network, the Venezuelan gas injection plant and international investment activities. Investing income decreased $3.6 million, or 8 percent, due primarily to $14 million lower interest earned on advances to Williams largely offset by higher interest income on advances to affiliates and long-term notes receivable. For information concerning the $44.5 million gain on sale of interest in subsidiary in 1997, see Note 2. The $66 million gain on sales of assets in 1997 results from the sale of Williams Holdings' interest in the liquids and condensate reserves in the West Panhandle field of Texas (see Note 5). Minority interest in (income) loss of consolidated subsidiaries in 1998 is $30.2 million favorable as compared to 1997 due primarily to losses experienced by Williams Communications Solutions, LLC which has a 30 percent interest held by minority shareholders. Other income (expense) -- net is $15.7 million unfavorable as compared to 1997 due primarily to 1998 litigation accruals and loss provisions totaling $11 million related to assets previously sold, and the effect of a 1997 gain of $4 million on the termination of interest-rate swap agreements.

The $139.2 million, or 90 percent, decrease in the provision for income taxes on continuing operations is primarily a result of lower pre-tax income, partially offset by a higher effective income tax rate in 1998. The

F-5

effective income tax rate in 1998 exceeds the federal statutory rate due primarily to the effects of state income taxes and the effects of non-deductible costs, including goodwill. The effective tax rate in 1997 is less than the federal statutory rate due primarily to the effect of the non-taxable gain recognized in 1997 (see Note 2) and income tax credits from coal-seam gas production, partially offset by the effects of state income taxes.

The 1998 and 1997 losses on discontinued operations are attributable to loss provisions for contractual obligations related to the sale of the net assets of the MAPCO coal business in 1996 (see Note 3).

The 1998 and 1997 extraordinary losses result from the early extinguishment of debt (see Note 7).

1997 vs. 1996

CONSOLIDATED OVERVIEW. Williams Holdings' revenues increased $1.4 billion, or 26 percent, due primarily to increased marketing of crude oil and refined products and higher revenues at Communications reflecting increased business activity and revenue contributed by acquisitions, including the 1997 combination of the Nortel customer premise equipment sales and services operations. Partially offsetting these increases was the $141 million impact in 1997 of reporting certain revenues net of costs within Energy Services (see Note 1).

Segment costs and expenses increased $1.4 billion, or 31 percent, due primarily to costs associated with the increased marketing of crude oil and refined products, higher costs and expenses at Communications and $50 million for asset impairments, partially offset by the $141 million impact in 1997 of reporting certain costs net in revenues within Energy Services (see Note 1).

Operating income decreased $95 million, or 18 percent, reflecting the change in revenues and segment costs and expenses discussed above and comprised primarily of a $63 million decrease at Communications and a $20 million decrease at Energy Services. Income from continuing operations before extraordinary loss and income taxes decreased $75 million, or 14 percent, reflecting the lower operating income, increased interest accrued resulting from higher capital expenditures and the effect of the $37 million gain in 1996 on sales of assets, partially offset by a $45 million gain in 1997 on the sale of interest in subsidiary and a $66 million gain in 1997 on the sale of assets.

ENERGY MARKETING & TRADING'S revenues increased $276.4 million, or 14 percent, due primarily to a $488 million increase in marketing of crude oil and refined products from the Memphis refinery. This increase reflects increased demand for petroleum products, aggressive marketing in the Memphis and Ohio River Valley areas and $183 million from the inclusion of Lexas Oil operations, which prior to July 1997 were unconsolidated. Partially offsetting this increase was a $125 million decrease in revenues from energy trading and price-risk management activities, $77 million lower marketing of natural gas liquids associated with Midstream's natural gas liquids transportation activities and a $16 million decrease in revenues from the propane marketing business. The $125 million decrease in revenues from energy trading and price-risk management activities resulted from the 1997 reporting on a net margin basis of certain natural gas and gas liquids marketing operations previously not considered to be included in trading operations. Excluding this decrease, energy trading and price-risk management revenues increased $16 million due primarily to the initial income recognition from long-term electric power contracts, increased physical and notional natural gas volumes of 22 percent and 44 percent, respectively, higher petroleum trading volumes, revenues from new project financing services for energy producers and the sale of excess transportation capacity, partially offset by lower natural gas trading margins as a result of decreased price volatility. The $77 million decrease in marketing of natural gas liquids results mainly from significantly lower natural gas liquids sales prices. The $16 million decrease in revenues from the propane marketing business resulted from the $24 million effect of the sale of certain propane and liquid fertilizer assets in 1996, partially offset by increased propane sales volumes primarily from acquisitions.

Costs and operating expenses increased $335 million, or 19 percent, due primarily to $526 million of additional costs associated with the marketing of crude oil and refined products from the Memphis refinery, $23 million of increased operating expenses associated with propane marketing acquisitions and growth initiatives and a $16 million increase in propane purchase costs relating to increased volumes, partially offset by the $141 million effect of the 1997 reporting on a net margin basis of certain natural gas and gas liquids

F-6

marketing operations previously not considered to be included in trading operations, $73 million lower costs of marketing natural gas liquids associated with Midstream's natural gas liquids transportation activities and $21 million associated with the sale of certain propane and liquid fertilizer assets. Selling, general and administrative expenses increased $32 million, or 52 percent, due primarily to propane business acquisitions and the expenses associated with expansion of certain business growth platforms.

Segment profit decreased $85.1 million, or 61 percent, due primarily to $38 million lower gross margins on the marketing of crude oil and refined products from the Memphis refinery, $32 million higher selling, general and administrative expenses, $23 million of increased operating expenses associated with propane marketing acquisitions and growth initiatives, and $10 million lower gross margins on propane marketing operations, partially offset by the $16 million increase in net energy trading and price-risk management revenues and a $6 million recovery of an account previously written off as a bad debt.

EXPLORATION & PRODUCTION'S revenues increased $47.7 million, or 58 percent, due primarily to the $20 million effect of higher average natural gas sales prices for company-owned production, the $14 million effect of higher average natural gas sales prices from the sale of volumes from the Royalty Trust and royalty interest owners, and the $9 million effect of a 21 percent increase in company-owned production volumes.

Costs and operating expenses increased $23 million, or 32 percent, due primarily to higher Royalty Trust natural gas purchase prices, increased production activities and higher dry hole costs.

Segment profit increased $27.5 million, from $2.8 million in 1996, due primarily to the increase in average natural gas sales prices and company-owned production volumes, partially offset by higher expenses associated with increased activity levels.

MIDSTREAM GAS & LIQUIDS' revenues increased $155.2 million, or 20 percent, due primarily to $53 million related to a full year of Canadian marketing operations in 1997 as compared to four months in 1996, $44 million of higher natural gas liquids sales from processing activities, the receipt of $8 million of business interruption insurance proceeds related to a 1996 claim, and higher gathering, processing and condensate revenues of $40 million, $5 million and $11 million, respectively. These increases were slightly offset by the impact of the January 1997 sale of the West Panhandle operations. The $44 million increase in natural gas liquids sales from processing activities is due to a 37 percent increase in volumes, slightly offset by lower average sales prices. Gathering revenues increased as a result of a 16 percent increase in volumes following the transfer of Williams Gas Pipelines Central (a wholly-owned subsidiary of Williams Holdings' parent) gathering assets to Midstream Gas & Liquids in the last half of 1996.

Costs and operating expenses increased $154.4 million, or 35 percent, due primarily to higher fuel and replacement gas purchases associated with gathering and processing activities, the $52 million impact of a full year of Canadian marketing operations, costs associated with the gathering assets transferred to Midstream Gas & Liquids from Williams Gas Pipelines Central and higher operating and maintenance and depreciation expenses, slightly offset by the $13 million effect of the sale of the West Panhandle operations.

Other (income) expense -- net for 1996 includes a $20 million gain from the property insurance coverage associated with construction of replacement gathering facilities and $6 million of gains from the sale of two small gathering systems, partially offset by $5 million of environmental remediation accruals.

Segment profit decreased $23.2 million, or 8 percent, due primarily to the $30 million effect of lower per-unit liquids margins, an $18 million impact of the sale of the West Panhandle operations, and $12 million lower insurance recoveries in 1997 as compared to 1996, partially offset by the $24 million effect of increased liquids volumes sold and the transfer of gathering assets from Williams Gas Pipelines Central.

PETROLEUM SERVICES' revenues increased $100.8 million, or 4 percent, due primarily to a $27 million increase in ethanol sales, $25 million from new fleet management and mobile computer technology operations, a $24 million increase in product sales from transportation activities and $18 million higher retail sales revenues. Ethanol sales increased as a result of 22 percent higher sales volumes, partially offset by lower average ethanol sales prices. Ethanol production was reduced during the second half of 1996 due to unfavorable market conditions. The retail sales increase reflects higher gasoline and merchandise sales

F-7

following the EZ-Serve convenience stores acquisition, partially offset by lower diesel sales. A 5 percent increase in processed volumes sold was offset by slightly lower average refined product sales prices. Products pipeline shipments and average rates were comparable to 1996.

Costs and operating expenses increased $33.6 million, or 1 percent, due primarily to a $35 million increase in retail costs following the EZ-Serve convenience stores acquisition, $33 million associated with the new fleet management and mobile computer technology operations, $23 million higher product purchases associated with transportation activities, $15 million higher operating expenses associated with increased refinery throughput and maintenance activity, and $9 million higher costs from increased ethanol production, largely offset by $84 million lower crude oil costs at the refineries.

Segment profit increased $60.8 million, or 43 percent, due primarily to a $71 million increase from petroleum refining operations and a $15 million increase related to increased ethanol sales volumes and per-unit margins, partially offset by an $18 million decrease from retail operations and $9 million of losses associated with the new fleet management and mobile computer technology operations. The $71 million petroleum refining increase reflects higher per-unit margins and 5 percent higher volumes processed, partially offset by $10 million of higher costs associated with increased maintenance activity. The retail operations decrease reflects the additional costs associated with the implementation of strategic growth initiatives and lower per-unit margins on gasoline sales.

COMMUNICATIONS SOLUTIONS' revenues increased $638.4 million, or 112 percent, due primarily to acquisitions which contributed revenues of approximately $556 million, including $536 million from the April 30, 1997, combination of the Nortel customer premise equipment sales and services operations. Additionally, increased business activity resulted in a $119 million revenue increase in new system sales, partially offset by a $46 million decrease in system modification revenues.

Costs and operating expenses increased $460 million, or 105 percent, due primarily to the $393 million impact of the combination with Nortel. In addition, costs and operating expenses increased due to $50 million of higher costs associated with increased new systems sales activity and $16 million of higher costs related to system modification activity. Selling, general and administrative expenses increased $148 million, or 129 percent, due primarily to the combination with Nortel in addition to costs associated with expanding the infrastructure for future growth.

Segment profit increased $33 million from $14.3 million in 1996, due primarily to the combination with Nortel, partially offset by increased expenses associated with expanding the infrastructure.

NETWORK APPLICATIONS' revenues increased $84.7 million, or 65 percent, due primarily to 1997 acquisitions which contributed revenues of approximately $81 million.

Costs and operating expenses increased $83 million, or 86 percent, due primarily to the $68 million impact of acquisitions and higher expenses for developing and expanding video transmission services. Selling, general and administrative expenses increased $46 million, or 94 percent, due primarily to acquisitions and higher expenses for expanding the infrastructure for future growth.

Other (income) expense -- net in 1997 includes charges totaling $49.8 million related to the decision and formulation of a plan to sell the learning content business ($28 million), and the write-down of assets and development expenses associated with certain advanced applications (see Note 5).

Segment loss increased $93.6 million to $108.7 million, due primarily to the $49.8 million in charges described above and the expense of developing infrastructure while integrating the most recent acquisitions.

NETWORK SERVICES' revenues increased $31.9 million to $43 million in 1997, reflecting $14 million contributed by a March 1997 acquisition, $11 million from fiber assets transferred from Network Applications in late 1997 and internal growth.

Costs and operating expenses increased $27 million from $5 million in 1996, reflecting a $15 million effect of the transfer of fiber assets from Network Applications late in 1997 and $8 million from the March 1997 acquisition.

F-8

Segment profit decreased $2.5 million, or 43 percent, due primarily to an increase in selling, general and administrative expenses.

GENERAL CORPORATE EXPENSES increased $20.5 million, or 41 percent, due primarily to higher employee compensation expense, $10 million of costs related to the MAPCO acquisition, and a higher cost allocation percentage from Williams resulting from the combination of customer-premise equipment sales and service operations with Nortel and an increased level of other operations. Interest accrued increased $38.6 million, or 41 percent, due primarily to higher borrowing levels including increased borrowing under the $1 billion bank-credit facility and commercial paper program, partially offset by a lower average interest rate. The lower average interest rate reflects lower rates on new 1997 borrowings as compared to previously outstanding borrowings. Interest capitalized increased $14.5 million, from $4.8 million in 1996, due primarily to capital expenditures for the Discovery pipeline project and Communications' fiber-optic network. Investing income increased $5.2 million, or 13 percent, due primarily to interest earned on increased advances to Williams. For information concerning the $44.5 million 1997 gain on sale of interest in subsidiary, see Note 2. The $66 million 1997 gain on sales of assets results from the sale of Williams Holdings' interest in the liquids and condensate in the West Panhandle field of Texas (see Note 5). The $36.5 million 1996 gain on sales of assets results from the sale of the fertilizer and Iowa propane assets and the sale of certain communication rights (see Note 5). The $18.2 million minority interest in income of consolidated subsidiaries in 1997 is related primarily to the 30 percent interest held by Williams Communications Solutions, LLC's minority shareholder (see Note 2). The $17.4 million unfavorable change in other income (expense) -- net in 1997 is due primarily to $9 million of costs associated with Williams Holdings' sales of receivables program started in 1997, and the effects of gains realized on the sale of corporate aircraft in 1996 and $5 million of favorable accrual adjustments in 1996.

The provision for income taxes on continuing operations decreased $16.6 million, or 10 percent. The effective income tax rate in 1997 is less than the federal statutory rate due primarily to the effect of the non-taxable gain recognized in 1997 (see Note 2) and income tax credits from coal-seam gas production, partially offset by the effects of state income taxes. The effective tax rate in 1996 is less than the federal statutory rate due primarily to income tax credits from research activities and coal-seam gas production, partially offset by the effects of state income taxes. In addition, the 1996 tax provision includes recognition of favorable state income tax adjustments of $6 million.

On September 10, 1996, Williams Holdings sold the net assets of the MAPCO coal business to Alliance Coal Corporation for $236 million in cash. The sale resulted in losses in 1997 and 1996 which are reported as discontinued operations along with the operating results for 1996 (see Note 3).

The 1997 extraordinary loss results from the early extinguishment of debt (see Note 7).

FINANCIAL CONDITION AND LIQUIDITY

MAPCO Acquisition

On March 28, 1998, Williams (Williams Holdings' parent) completed the acquisition of MAPCO Inc. by exchanging 1.665 shares of Williams common stock for each outstanding share of MAPCO common stock. In addition, outstanding MAPCO employee stock options were converted into 5.7 million shares of Williams common stock. Upon completion, 98.8 million shares of Williams common stock were issued. MAPCO was engaged in the NGL pipeline, petroleum refining and marketing, and propane marketing businesses. Upon completion of the merger, Williams transferred its interest in MAPCO to Williams Holdings, and MAPCO became part of the Energy Services business unit.

The merger constituted a tax-free reorganization and has been accounted for as a pooling of interests. Accordingly, all prior period financial information presented includes the combined results of operations, financial condition and liquidity of MAPCO and Williams Holdings.

F-9

Liquidity

Williams Holdings considers its liquidity to come from two sources:
internal liquidity, consisting of available cash investments, and external liquidity, consisting of borrowing capacity from available bank-credit facilities and its commercial paper program, which can be utilized without limitation under existing loan covenants, as amended in January 1999. Williams Holdings is a participant in Williams' $1 billion bank-credit facility and has access to the entire $1 billion facility, subject to borrowing by other affiliated companies. At December 31, 1998, Williams Holdings had access to $361 million of liquidity including $306 million available under the $1 billion bank-credit facility. This compares with liquidity of $165 million at December 31, 1997, and $290 million at December 31, 1996.

During 1998, Williams Holdings increased its commercial paper program to $1 billion from $650 million. The commercial paper program is backed by short-term bank-credit facilities totaling $1 billion. At December 31, 1998, $903 million of commercial paper was outstanding under the program. In January 1999, Williams Holdings' commercial paper program was increased to $1.4 billion with the short-term bank-credit facilities increased to the same amount.

In addition, Williams Holdings and its subsidiaries had net amounts receivable from Williams totaling $1 billion at December 31, 1998, excluding parent company debentures with a face value of $360 million (see Note 4), compared to $231 million at December 31, 1997, and $124 million at December 31, 1996. The increase in amounts receivable from Williams at December 31, 1998 from December 31, 1997, reflects additional advances to the parent under Williams' cash-management system, primarily due to proceeds from Williams Holdings' commercial paper program, long-term debt issuances and proceeds from the sale of limited partnership member interest.

Williams Holdings believes its parent can meet its cash needs. Williams has access to $738 million of liquidity at December 31, 1998 including $306 million available under its $1 billion bank-credit facility previously discussed, as compared to liquidity of $166 million and $630 million at December 31, 1997 and 1996, respectively. The lower liquidity level at December 31, 1997, reflected the use of the $1 billion bank-credit facility to provide interim financing related to a debt restructuring program. This restructuring program was completed during the first quarter of 1998 and a significant portion of the $1 billion bank-credit facility was repaid with the proceeds from long-term financings.

At December 31, 1998, Williams Holdings has $595 million of shelf availability remaining under registration statements filed with the Securities and Exchange Commission. These registration statements may be used to issue a variety of debt or equity securities. Interest rates and market conditions will affect amounts borrowed, if any, under these arrangements. In addition, Williams Holdings uses short-term uncommitted bank lines to manage liquidity. Williams Holdings believes any additional financing arrangements can be obtained on reasonable terms if required.

On November 19, 1998, Williams Holdings announced that it intends to sell a minority interest in its communications business. The initial equity offering is expected to be filed in the second quarter of 1999 and yield proceeds of $500 million to $750 million. In addition, Williams Holdings expects Communications to issue high-yield public debt of approximately $1.3 billion to $1.5 billion in 1999. On February 8, 1999, Williams Holdings announced that, simultaneously with the public equity offering, SBC Communications plans to acquire up to a 10 percent interest in Williams Holdings' communications business for an investment of up to $500 million. Proceeds from these transactions will be reinvested in the continued construction of Williams Holdings' national fiber-optic network and other expansion opportunities.

During 1998, Williams Holdings entered into an agreement described as a securitized asset lease program designed to fund up to $750 million of capital expenditures for the fiber-optic network. A total of $463 million remains available under this agreement. See Note 12 for additional information.

Williams Holdings had a net working-capital deficit of $640 million at December 31, 1998, compared with $352 million at December 31, 1997. The increase in the working-capital deficit at December 31, 1998, as compared to prior year-end is primarily a result of short-term borrowings under the commercial paper program. Williams Holdings manages its borrowings to keep cash and cash equivalents at a minimum and has

F-10

relied on bank-credit facilities to provide flexibility for its cash needs. As a result, it historically has reported negative working capital.

During 1999, Williams Holdings expects to finance capital expenditures, investments and working-capital requirements through cash generated from operations, Communications' initial equity and high-yield debt offerings, and the use of the available portion of its $1 billion bank-credit facility and asset lease program, commercial paper, short-term uncommitted bank lines, private borrowings, advances from its parent or debt offerings.

Operating Activities

Cash provided by continuing operating activities was: 1998 -- $86 million; 1997 -- $560 million; and 1996 -- $390 million. Cash provided by operating activities in 1997 includes $200 million of proceeds from the sale of receivables program begun in 1997. Energy trading assets and liabilities increased in 1998 due primarily to increased physical power trading activity.

Financing Activities

Net cash provided by financing activities was: 1998 -- $2.3 billion; 1997 -- $575 million; and 1996 -- $265 million. Long-term debt proceeds, net of principal payments, were $567 million, $122 million and $573 million during 1998, 1997 and 1996, respectively. Notes payable proceeds, net of notes payable payments, were $210 million and $542 million during 1998 and 1997, respectively. Notes payable payments, net of notes payable proceeds, were $161 million during 1996. The increase in net new borrowings during 1998, 1997 and 1996 reflects borrowings to fund capital expenditures, investments and acquisition of businesses.

Long-term debt, at December 31, 1998, was $2.9 billion, including $948 million in advances from affiliates, compared with $1.5 billion at December 31, 1997, and $1.4 billion at December 31, 1996. At December 31, 1997 and 1996, $162 million and $129 million, respectively, in current debt obligations were classified as non-current obligations based on Williams Holdings' intent and ability to refinance on a long-term basis. The 1998 increase in long-term debt is due primarily to $425 million of public debt issued and $948 million of advances from affiliates. The long-term debt to debt-plus-equity ratio was 42.6 percent at December 31, 1998 compared to 30.2 percent and 31.1 percent at December 31, 1997 and 1996, respectively. If short-term notes payable and long-term debt due within one year are included in the calculations, these ratios would be 51.1 percent, 39.5 percent and 31.8 percent, respectively.

Williams Holdings paid cash dividends to Williams of $14 million, $114 million and $148 million in 1998, 1997 and 1996, respectively, and received cash capital contributions from Williams of $213 million, $10 million and $2 million in 1998, 1997 and 1996, respectively.

During 1998, Williams Holdings received proceeds of $200 million from the sale of a limited partnership minority interest to an outside investor (see Note 13).

Investing Activities

Net cash used by investing activities was: 1998 -- $2.4 billion; 1997 -- $1.2 billion; and 1996 -- $590 million. Capital expenditures of Energy Services, primarily to expand and modernize gathering and processing facilities and refineries, were $701 million in 1998, $451 million in 1997, and $398 million in 1996. Capital expenditures of Communications were $304 million in 1998, $276 million in 1997, and $67 million in 1996. The 1998 and 1997 expenditures include the expansion of the fiber-optic network. Budgeted capital expenditures and investments for all business units for 1999 are estimated to be approximately $4.4 billion, including $2.2 billion for the fiber-optic network expansion and expenditures to expand and modernize gathering and processing facilities, refineries and other international investment activities. Capital expenditures for 1999 and 2000 for the fiber-optic network are expected to total $3.4 billion.

During 1998, Williams Holdings made a $100 million advance and a $150 million investment in a telecommunications business in Brazil. In addition, during 1998 Williams Holdings made an $85 million investment in a Texas refined petroleum products pipeline joint venture.

F-11

Subsequent to December 31, 1998, Williams Holdings exercised an option to increase its investment in the Brazilian cellular phone venture. Negotiations are currently underway, and the company could invest up to $265 million, which is included in budgeted capital expenditures above, during the first quarter of 1999.

On April 30, 1997, Williams Holdings and Northern Telecom (Nortel) combined their customer-premise equipment sales and services operations into a limited liability company, Williams Communications Solutions, LLC. In addition, Williams Holdings paid $68 million to Nortel. See Note 2 for additional information. During 1997, Williams Holdings also purchased a 20 percent interest in a foreign telecommunications business for $65 million in cash and made a $59 million cash investment in the 50 percent owned Discovery pipeline project. During 1996 Williams Holdings acquired various communications technology businesses totaling $165 million in cash.

During 1997, Williams Holdings received proceeds of $66 million from the sale of interests in the West Panhandle field. During 1996, Williams Holdings received proceeds of $236 million from the sale of its MAPCO coal operations (see Note 3).

Other Commitments

During 1998, Energy Marketing & Trading entered into a 15-year contract giving Williams Holdings the right to receive fuel conversion services for purposes of generating electricity. This contract also gives Williams Holdings the right to receive installed capacity as well as certain ancillary services. Annual committed payments under the contract range from $140 million to $165 million, resulting in total committed payments of approximately $2.3 billion. Williams Holdings' intent is to resell power generated as a result of this service into markets in the western region of the United States. Williams Holdings also intends to resell capacity and ancillary services into such markets as the opportunities arise.

Subsequent event

On March 18, 1999, Williams' board of directors approved the merger of Williams Holdings with Williams. Upon completion of the merger, which is expected to be in the second or third quarter of 1999, Williams will assume all liabilities and obligations of Williams Holdings.

NEW ACCOUNTING STANDARDS

See Note 1 for the effects of Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities," Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities" and Emerging Issues Task Force Issue No. 98-10, "Accounting for Contracts Involved in Energy Trading and Risk Management Activities."

EFFECTS OF INFLATION

Williams Holdings' cost increases in recent years have benefited from relatively low inflation rates during that time. Approximately 62 percent of Williams Holdings' property, plant and equipment was acquired or constructed during the last seven years, a period of relatively low inflation. Within Energy Services, operating costs are influenced to a greater extent by specific price changes in oil and gas and related commodities than by changes in general inflation. Crude, refined product and natural gas liquids prices are particularly sensitive to OPEC production levels and/or the market perceptions concerning the supply and demand balance in the near future. See Market Risk Disclosures in Item 7a for additional information concerning the impact of commodity price risk. The activities of Communications have historically not been significantly affected by the effects of inflation.

ENVIRONMENTAL

Williams Holdings is a participant in certain environmental activities in various stages involving assessment studies, cleanup operations and/or remedial processes. The sites are being monitored by Williams Holdings, other potentially responsible parties, the U.S. Environmental Protection Agency (EPA), or other

F-12

governmental authorities in a coordinated effort. In addition, Williams Holdings maintains an active monitoring program for its continued remediation and cleanup of certain sites connected with its refined products pipeline activities. Williams Holdings has both joint and several liability in some of these activities and sole responsibility in others. Current estimates of the most likely costs of such cleanup activities, after payments by other parties, are approximately $47 million, all of which is accrued at December 31, 1998. Williams Holdings expects to seek recovery of approximately $14 million of accrued costs from states in accordance with laws permitting reimbursement of certain expenses associated with underground storage tank containment problems and repairs. Williams Holdings will fund these costs from operations and/or available bank-credit facilities. The actual costs incurred will depend on the final amount, type and extent of contamination discovered at these sites, the final cleanup standards mandated by the EPA or other governmental authorities, and other factors.

YEAR 2000 COMPLIANCE

Williams and its wholly-owned subsidiaries, which includes Williams Holdings, initiated an enterprise-wide project in 1997 to address the year 2000 compliance issue for both traditional information technology areas and non-traditional areas, including embedded technology which is prevalent throughout the company. This project focuses on all technology hardware and software, external interfaces with customers and suppliers, operations process control, automation and instrumentation systems, and facility items. The phases of the project are awareness, inventory and assessment, renovation and replacement, testing and validation. The awareness and inventory/assessment phases of this project as they relate to both traditional and non-traditional information technology areas have been substantially completed. During the inventory and assessment phase, all systems with possible year 2000 implications were inventoried and classified into five categories: 1) highest, business critical, 2) high, compliance necessary within a short period of time following January 1, 2000, 3) medium, compliance necessary within 30 days from January 1, 2000, 4) low, compliance desirable but not required, and 5) unnecessary. Categories 1 through 3 were designated as critical and are the major focus of this project. Renovation/replacement and testing/validation of critical systems is expected to be completed by June 30, 1999, except for replacement of certain critical systems scheduled for completion by September 1, 1999. Some non-critical systems may not be compliant by January 1, 2000.

Testing and validation activities have begun and will continue throughout the process. Year 2000 test labs are in place and operational. As expected, few problems have been detected during testing for items believed to be compliant. The following table indicates the project status for traditional information technology and non-traditional areas by business unit. The tested category indicates the percentage that has been fully tested or otherwise validated as compliant. The untested category includes items that are believed to be compliant but which have not yet been validated. The not compliant category includes items which have been identified as not year 2000 compliant. The unknown category includes items identified during the assessment phase which require additional follow-up to determine whether they are compliant.

                    BUSINESS UNIT                      TESTED   UNTESTED   NOT COMPLIANT   UNKNOWN

Williams Holdings initiated a formal communications process with other companies in 1998 to determine the extent to which those companies are addressing year 2000 compliance. In connection with this process, Williams Holdings has sent approximately 10,000 letters and questionnaires to third parties including customers, vendors and service providers. Additional communications are being mailed during 1999. Williams Holdings is evaluating responses as they are received or otherwise investigating the status of these companies'

F-13

year 2000 compliance efforts. As of December 31, 1998, approximately 38 percent of the companies contacted have responded and virtually all of these have indicated that they are already compliant or will be compliant on a timely basis. Where necessary, Williams Holdings will be working with key business partners to reduce the risk of a break in service or supply and with non-compliant companies to mitigate any material adverse effect on Williams Holdings.

Williams Holdings expects to utilize both internal resources and external contractors to complete the year 2000 compliance project. Williams Holdings has a core group of 106 people involved in this enterprise-wide project. This includes 13 individuals responsible for coordinating, organizing, managing, communicating, and monitoring the project and another 93 staff members responsible for completing the project. Depending on which phase the project is in and what area is being focused on at any given point in time, there can be up to an additional 1,000 employees who are also contributing a portion of their time to the completion of this project. The Communications business unit has contracted with an external contractor at a cost of approximately $3 million to assist in all phases and various areas of the project. Within Energy Services, two external contractors are being utilized at a total cost of approximately $1 million.

Several previously planned system implementations are scheduled for completion on or before September 1, 1999, which will lessen possible year 2000 impacts. For example, a new year 2000 compliant payroll/human resources system, was implemented January 1, 1999. It replaced multiple human resources administration and payroll processing systems previously in place. The Communications business unit has a major service information management system implementation and other system implementations currently in process necessary to integrate the operations of its many components acquired in past acquisitions. These systems will address the year 2000 compliance issues in certain areas. Within the Energy Services business unit, major applications had been replaced or were being replaced by MAPCO prior to its acquisition by Williams Holdings. Those applications have been incorporated into the enterprise-wide project and remaining system replacements are proceeding on schedule. In situations where planned system implementations will not be in service timely, alternative steps are being taken to make existing systems compliant.

Although all critical systems over which Williams Holdings has control are planned to be compliant and tested before the year 2000, Williams Holdings has identified two areas that would equate to a most reasonably likely worst case scenario. First is the possibility of service interruptions due to non-compliance by third parties. For example, power failures along the communications network or transportation systems would cause service interruptions. This risk should be minimized by the enterprise-wide communications effort and evaluation of third-party compliance plans. Another area of risk for non-compliance is the delay of system replacements scheduled for completion during 1999. The status of these systems is being closely monitored to reduce the chance of delays in completion dates. It is not possible to quantify the possible financial impact if this most reasonably likely worst case scenario were to come to fruition.

Initial contingency planning began during 1998; however, significant focus on that phase of the project will take place in 1999. Guidelines for that process were issued in January 1999 in the form of a formal business continuity plan. Contingency plans are being developed for critical business processes, critical business partners, suppliers and system replacements that experience significant delays. These plans are expected to be defined by August 31, 1999 and implemented where appropriate.

Costs incurred for new software and hardware purchases are being capitalized and other costs are being expensed as incurred. Williams Holdings currently estimates the total cost of the enterprise-wide project, including any accelerated system replacements, to be approximately $42 million. Prior to 1998 and during the first quarter of 1998, Williams Holdings was conducting the project awareness and inventory/assessment phases of the project and incurred costs totaling $2 million. During the second quarter of 1998, $2 million was spent on the renovation/replacement and testing/validation phases and completion of the inventory/assessment phase. The third and fourth quarters of 1998 focused on the renovation/replacement and testing/validation phases, and $7 million was incurred. During the first-quarter 1999, renovation/replacement and testing/validation will continue, contingency planning will begin and $11 million is expected to be spent. During the second quarter of 1999, the primary focus is expected to shift to testing/validation and contingency planning, and $10 million is expected to be spent. The third and fourth quarters of 1999 will focus mainly on

F-14

contingency planning and final testing with $10 million expected to be spent. Of the $11 million incurred to date, approximately $9 million has been expensed, and approximately $2 million has been capitalized. Of the $31 million of future costs necessary to complete the project within the schedule described, approximately $28 million will be expensed and the remainder capitalized. This estimate does not include Williams Holdings' potential share of year 2000 costs that may be incurred by partnerships and joint ventures in which the company participates but is not the operator. The costs of previously planned system replacements are not considered to be year 2000 costs and are, therefore, excluded from the amounts discussed above.

The preceding discussion contains forward-looking statements including, without limitation, statements relating to the company's plans, strategies, objectives, expectations, intentions, and adequate resources, that are made pursuant to the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Readers are cautioned that such forward-looking statements contained in the year 2000 update are based on certain assumptions which may vary from actual results. Specifically, the dates on which the company believes the year 2000 project will be completed and computer systems will be implemented are based on management's best estimates, which were derived utilizing numerous assumptions of future events, including the continued availability of certain resources, third-party modification plans and other factors. However, there can be no guarantee that these estimates will be achieved, or that there will not be a delay in, or increased costs associated with, the implementation of the year 2000 project. Other specific factors that might cause differences between the estimates and actual results include, but are not limited to, the availability and cost of personnel trained in these areas, the ability to locate and correct all relevant computer code, timely responses to and corrections by third parties and suppliers, the ability to implement interfaces between the new systems and the systems not being replaced, and similar uncertainties. Due to the general uncertainty inherent in the year 2000 problem, resulting in large part from the uncertainty of the year 2000 readiness of third parties, the company cannot ensure its ability to timely and cost effectively resolve problems associated with the year 2000 issue that may affect its operations and business, or expose it to third-party liability.

ITEM 7A. MARKET RISK DISCLOSURES

INTEREST RATE RISK

Affiliate Debentures

Williams Holdings holds an investment in Williams convertible debentures with a face value of $360 million, bearing interest at a fixed rate of 6 percent and maturing in 2005 (see Note 4). The fair value of Williams Holdings' investment is based on the prices of similar securities with similar terms and credit ratings (see Note 15).

Due From Parent

Williams Holdings has interest rate risk exposure related to the advances from and to Williams depending on the cash position of each subsidiary and/or for other specified business requirements (see Notes 15 and 16). Amounts are payable on demand, however, the net amount due from Williams at December 31, 1998, is classified as long-term as there is no expectation that Williams Holdings and its subsidiaries will demand payment in the next year. Interest rates for these advances vary with current market conditions. Accordingly fair value is estimated to approximate historically recorded amounts.

Debt

Williams Holdings' interest rate risk exposure primarily results from its debt portfolio which is influenced by short-term rates, primarily LIBOR-based borrowings from commercial banks and the issuance of commercial paper, and long-term U.S. Treasury rates. To mitigate the impact of fluctuations in interest rates, Williams Holdings targets to maintain a significant portion of its debt portfolio, including debt with Williams, in fixed rate debt. Williams Holdings also utilizes interest-rate swaps to change the ratio of its fixed and variable rate debt portfolio based on management's assessment of future interest rates, volatility of the yield curve and Williams Holdings' ability to access the capital markets in a timely manner. Williams Holdings periodically enters into interest rate forward contracts to establish an effective borrowing rate for anticipated

F-15

long-term debt issuances. The maturity of Williams Holdings' long-term debt portfolio is influenced by the life of its operating assets.

At December 31, 1998, the amount of Williams Holdings' fixed and variable rate debt was at targeted levels. Williams Holdings has traditionally maintained an investment grade credit rating as one aspect of managing its interest rate risk. In order to fund its 1999 capital expenditure plan, Williams Holdings will need to access various sources of liquidity, which will likely include traditional borrowing and leasing markets, while its Telecommunications business also anticipates accessing high yield debt markets and equity markets.

The following table provides information as of December 31, 1998, about Williams Holdings' external notes payable, long-term debt and interest-rate swaps that are subject to interest rate risk. For notes payable and long-term debt, the table presents principal cash flows and weighted-average interest rates by expected maturity dates. For interest-rate swaps, the table presents notional amounts and weighted-average interest rates by contractual maturity dates. Notional amounts are used to calculate the contractual cash flows to be exchanged under the interest-rate swaps.

Debt With Affiliates

Williams Holdings has approximately $1 billion of long-term debt, including the current portion, with other Williams subsidiaries at December 31, 1998, bearing interest at a fixed rate of 5.57 percent and maturing in 2002. The fair value of the debt approximates the carrying value (see Notes 15 and 16).

COMMODITY PRICE RISK

Energy Marketing & Trading has trading operations that incur commodity price risk as a consequence of providing price risk management services to third-party customers. The trading operations have commodity price risk exposure associated with the crude oil, natural gas, refined products, natural gas liquids and electricity energy markets in the United States and the natural gas markets in Canada. The trading operations enter into energy contracts which include forward contracts, futures contracts, option contracts, swap agreements, commodity inventories and short- and long-term purchase and sale commitments which involve the physical delivery of an energy commodity. These energy contracts are valued at fair value and unrealized gains and losses from changes in fair value are recognized in income. The trading operations are subject to risk from changes in energy commodity market prices, the portfolio position of its financial instruments and physical commitments, the liquidity of the market in which the contract is transacted, changes in interest rates and credit risk. Energy Marketing & Trading manages market risk on a portfolio basis subject to the parameters established in its trading policy. A Risk Control Group, independent of the trading operations,

F-16

monitors compliance with the established trading policy and measures the risk associated with the trading portfolio.

Energy Marketing & Trading measures the market risk in its trading portfolio on a daily basis utilizing a value at risk methodology to estimate the potential one day loss from adverse changes in the fair value of its trading operations. At December 31, 1998, the value at risk for the trading operations was $8 million. Value at risk requires a number of key assumptions and is not necessarily representative of actual losses in fair value that could be incurred from the trading portfolio. Energy Marketing & Trading's value-at-risk model includes all financial instruments and physical positions and commitments in its trading portfolio and assumes that as a result of changes in commodity prices, there is a 97.5 percent probability that the one day loss in the fair value of the trading portfolio will not exceed the value at risk. The value-at-risk model uses historical simulation to estimate hypothetical movements in future market prices assuming normal market conditions based upon historical market prices. Value-at-risk does not consider that changing our trading portfolio in response to market conditions could affect market prices and could take longer to execute than the one-day holding period assumed in the value-at-risk model.

FOREIGN CURRENCY RISK

Williams Holdings has investments in companies whose operations are located in foreign countries, of which $95 million are accounted for using the cost method. Fair value for the cost-method investments is deemed to approximate their carrying amount, because estimating cash flows by year is not practicable given that the time frame for selling these investments is uncertain. Williams Holdings' financial results could be affected if the investments incur a permanent decline in value as a result of changes in foreign currency exchange rates and the economic conditions in foreign countries. Williams Holdings attempts to mitigate these risks by investing in different countries and business segments. Approximately 69 percent of the cost-method investments are in Asian countries and 27 percent in South American countries. Approximately 50 percent of the Asian investments and approximately 25 percent of the South American investments are in countries whose currencies have recently suffered significant devaluations and volatility. The ultimate duration and severity of the conditions in Asia and South America remain uncertain as does the long-term impact on Williams Holdings' investments.

REPORT OF INDEPENDENT AUDITORS

To the Board of Directors
Williams Holdings of Delaware, Inc.

We have audited the accompanying consolidated balance sheet of Williams Holdings of Delaware, Inc. as of December 31, 1998 and 1997, and the related consolidated statements of operations, stockholder's equity, and cash flows for each of the three years in the period ended December 31, 1998. Our audits also included the financial statement schedule listed in the Index at Item 14(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits. We did not audit the financial statements and schedules of MAPCO Inc., a wholly owned subsidiary (see Note 2), which statements reflect total assets constituting 26% of the related consolidated financial statement total for 1997, and which reflect net income constituting approximately 33% and 30% of the related consolidated financial statement totals for the years ended December 31, 1997 and 1996, respectively. Those statements and schedules were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to data included for MAPCO Inc. for those periods, is based solely on the report of the other auditors.

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 and the report of other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Williams Holdings of Delaware, Inc. at December 31, 1998 and 1997, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 1998, in conformity with generally accepted accounting principles. Also, in our opinion, based on our audits and the report of other auditors, the financial statement schedule referred to above, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of business

Williams Holdings of Delaware, Inc. (Williams Holdings) is a wholly owned subsidiary of The Williams Companies, Inc. (Williams). Operations of Williams Holdings are located principally in the United States and are organized into two industry groups: Energy Services and Communications.

Energy Services includes four operating segments: Energy Marketing & Trading, Exploration & Production, Midstream Gas & Liquids, and Petroleum Services. Energy Marketing & Trading offers price-risk management services and buys, sells and arranges for transportation/transmission of energy commodities -- including natural gas and gas liquids, crude oil and refined products, and electricity -- to local distribution companies and large industrial and commercial customers in North America and retail propane marketing in the upper midwest and southwest regions. Exploration & Production includes hydrocarbon exploration and production activities in the Rocky Mountain and Gulf Coast regions. Midstream Gas & Liquids is comprised of natural gas gathering and processing facilities in the Rocky Mountain, midwest and Gulf Coast regions, natural gas liquids pipelines in the Rocky Mountain, southwest, midwest and Gulf Coast regions and an anhydrous ammonia pipeline in the midwest. Petroleum Services includes petroleum refining and marketing in Alaska and the southeast, a petroleum products pipeline and ethanol production and marketing operations in the midwest region.

Communications consists of three operating segments: Communications Solutions, Network Applications, and Network Services. Communications Solutions includes consulting, installation and maintenance of customer-premise voice, data and video equipment and services for customers throughout North America. Network Applications' operations are located principally in the United States and include video, advertising distribution, and other multimedia transmission services (via terrestrial and satellite links) for the broadcast industry as well as business audio and video conferencing services. Network Services provides fiber-optic construction, transmission and management services throughout the United States.

Basis of presentation

Williams Holdings adopted Statement of Financial Accounting Standards (SFAS) No. 131, "Disclosures about Segments of an Enterprise and Related Information," during the fourth quarter of 1998. SFAS No. 131 establishes standards for reporting information about operating segments and related disclosures about products and services, geographic areas, and major customers. Prior year financial statements and notes were reclassified to conform to the requirements of SFAS No. 131. (See Note 19 for segment disclosures.)

Certain balance sheet and cash flow amounts for 1997 have been reclassified to conform to current classifications.

On March 28, 1998, Williams completed the acquisition of MAPCO Inc. (see Note 2). Upon completion of the merger, Williams transferred its interest in MAPCO to Williams Holdings, and MAPCO became part of the Energy Services business unit. The transaction has been accounted for as a pooling of interests and, accordingly, the consolidated financial statements and notes reflect the results of operations, financial position and cash flows as if the companies had been combined throughout the periods presented. The restated 1997 annual financial statements were filed with the Securities and Exchange Commission in a Form 8-K dated May 18, 1998. MAPCO was engaged in the natural gas liquids pipeline, petroleum refining and marketing and propane marketing businesses. Effective April 1, 1998, certain marketing activities of natural gas liquids (previously reported in Midstream Gas & Liquids) and petroleum refining (previously reported in Petroleum Services) were transferred to Energy Marketing & Trading and combined with its energy risk trading operations. As a result, revenues and segment profit amounts for 1997 and 1996 have been reclassified and reported within Energy Marketing & Trading. These marketing activities are reported through first-quarter 1998 on a "gross" basis in the Consolidated Statement of Operations as revenues and segment costs within

WILLIAMS HOLDINGS OF DELAWARE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Energy Marketing & Trading. Concurrent with completing the combination of such activities with the energy risk trading operations of Energy Marketing & Trading, the related contract rights and obligations of certain of these operations were recorded in the Consolidated Balance Sheet on a market-value basis consistent with Energy Marketing & Trading's accounting policy, and the statement of operations presentation relating to these operations was changed effective April 1, 1998, on a prospective basis, to reflect these revenues net of the related costs to purchase such items.

On April 30, 1997, Williams Holdings and Northern Telecom (Nortel) combined their customer-premise equipment sales and service operations into a limited liability company, Williams Communications Solutions, LLC (LLC) (see Note 2). Communications Solutions' revenues and segment profit amounts for 1997 include the operating results of the LLC beginning May 1, 1997.

Principles of consolidation

The consolidated financial statements include the accounts of Williams Holdings and its majority-owned subsidiaries. Companies in which Williams Holdings and its subsidiaries own 20 percent to 50 percent of the voting common stock, or otherwise exercise sufficient influence over operating and financial policies of the company, are accounted for under the equity method.

Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and cash equivalents

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

Inventory valuation

Inventories are stated at cost, which is not in excess of market, except for certain assets held for energy trading activities by Energy Marketing & Trading, which are primarily stated at fair value. The cost of inventories is primarily determined using the average-cost method, except for certain crude oil, refined products, and general merchandise inventories which are determined using the last-in, first-out (LIFO) method.

Investments

Williams Holdings' investment in subordinated debentures of Williams is classified as "available for sale" and is recorded at current market value with unrealized gains and losses reported net of income taxes as a component of other accumulated comprehensive income in stockholder's equity. Average cost is used to determine realized gains and losses. Williams Holdings' investment in Williams warrants is recorded at cost since the warrants are not traded on a securities exchange. As such, the fair value of the warrants is not readily determinable under generally accepted accounting principles, and Williams Holdings has no current intention of exercising the warrants in the future.

Property, plant and equipment

Property, plant and equipment is recorded at cost. Depreciation is provided primarily on the straight-line method over estimated useful lives. Gains or losses from the ordinary sale or retirement of property, plant and

F-25

WILLIAMS HOLDINGS OF DELAWARE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

equipment for the regulated pipelines are credited or charged to accumulated depreciation; other gains or losses are recorded in net income (loss).

Goodwill and other intangible assets

Goodwill, which represents the excess of cost over fair value of assets of businesses acquired, is amortized on a straight-line basis over periods from 10 to 30 years. Other intangible assets are amortized on a straight-line basis over periods from three to 11 years. Accumulated amortization at December 31, 1998 and 1997 was $128.9 million and $72.2 million, respectively. Amortization of intangible assets was $49.7 million, $29.2 million and $15.2 million in 1998, 1997 and 1996, respectively.

Revenue recognition

Revenues generally are recorded when services have been performed or products have been delivered. Communications Solutions primarily uses the percentage-of-completion method of recognizing revenues for services provided. At December 31, 1998 and 1997, costs in excess of billings, included in trade receivables, were $185.9 million and $144.6 million, respectively, and billings in excess of costs, included in accrued liabilities, were $49.4 million and $48.1 million, respectively. Network Services records revenues related to the sale of portions of its fiber-optic network upon completion of the construction of the respective network segments and upon acceptance of the fiber by the purchaser. Certain of Energy Marketing & Trading's activities are accounted for at fair value as described in Energy Trading Activities.

Energy trading activities

Energy Marketing & Trading has trading operations that enter into energy contracts to provide price-risk management services to its third-party customers. Energy contracts include forward contracts, futures contracts, option contracts, swap agreements, commodity inventories and short- and long-term purchase and sale commitments which involve physical delivery of an energy commodity. These energy contracts are valued at fair value and, with the exception of commodity inventories, are recorded in energy trading assets and energy trading liabilities in the Consolidated Balance Sheet. The net change in the fair value representing unrealized gains and losses is recognized in income currently and is recorded as revenues in the Consolidated Statement of Operations. Fair value, which is subject to change in the near term, reflects management's estimates using valuation techniques that reflect the best information available in the circumstances. This information includes various factors such as quoted market prices, estimates of market prices in the absence of quoted market prices, contractual volumes, estimated volumes under option and other arrangements that result in varying volumes, other contract terms, liquidity of the market in which the contract is transacted, credit considerations, time value and volatility factors underlying the positions. Energy Marketing & Trading reports its trading operations' physical sales transactions net of the related purchase costs, consistent with fair value accounting for such trading activities.

Williams Holdings also enters into energy derivative financial instruments and derivative commodity instruments (primarily futures contracts, option contracts and swap agreements) to hedge against market price fluctuations of certain commodity inventories and sales and purchase commitments. Unrealized and realized gains and losses on these hedge contracts are deferred and recognized in income in the same manner as the hedged item. These contracts are initially and regularly evaluated to determine that there is a high correlation between changes in the fair value of the hedge contract and fair value of the hedged item.

Impairment of long-lived assets

Williams Holdings evaluates the long-lived assets, including related intangibles, of identifiable business activities for impairment when events or changes in circumstances indicate, in management's judgment, that the carrying value of such assets may not be recoverable. The determination of whether an impairment has

F-26

WILLIAMS HOLDINGS OF DELAWARE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

occurred is based on management's estimate of undiscounted future cash flows attributable to the assets as compared to the carrying value of the assets. If an impairment has occurred, the amount of the impairment recognized is determined by estimating the fair value for the assets and recording a provision for loss if the carrying value is greater than fair value.

For assets identified to be disposed of in the future, the carrying value of these assets is compared to the estimated fair value less the cost to sell to determine if an impairment is required. Until the assets are disposed of, an estimate of the fair value is redetermined when related events or circumstances change.

Interest-rate derivatives

Williams Holdings enters into interest-rate swap agreements to modify the interest characteristics of its long-term debt. These agreements are designated with all or a portion of the principal balance and term of specific debt obligations. These agreements involve the exchange of amounts based on a fixed interest rate for amounts based on variable interest rates without an exchange of the notional amount upon which the payments are based. The difference to be paid or received is accrued and recognized as an adjustment of interest expense. Gains and losses from terminations of interest-rate swap agreements are deferred and amortized as an adjustment of the interest expense on the outstanding debt over the remaining original term of the terminated swap agreement. In the event the designated debt is extinguished, gains and losses from terminations of interest-rate swap agreements are recognized in income.

Williams Holdings enters into interest-rate forward contracts to lock in underlying treasury rates on anticipated long-term debt issuances. The settlement amounts upon termination of the contracts are deferred and amortized as an adjustment to interest expense of the issued long-term debt over the term of the referenced security underlying the settled forward contract.

Capitalization of interest

Williams Holdings capitalizes interest on major projects during construction. Interest is capitalized on borrowed funds at rates that approximate the average interest rate on related debt.

Income taxes

The operations of Williams Holdings and its subsidiaries, except for MAPCO Inc., are included in Williams' consolidated federal income tax return. MAPCO filed a separate consolidated federal income tax return during the period prior to the merger. Subsequent to the date of the merger, MAPCO's operations will be included in Williams' consolidated federal income tax return.

The provision for income taxes is computed on a separate-company basis for Williams Holdings. Prior to the merger, income taxes were computed separately for the Williams Holdings and MAPCO consolidated groups and then combined. Williams Holdings makes payments to Williams under the same timing and minimum amount requirements as if the payments are being made directly to the taxing authorities. 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 Williams Holdings' assets and liabilities.

Related party transactions

Williams charges its subsidiaries, including Williams Holdings and its subsidiaries, for certain corporate general and administrative expenses which are directly identifiable or allocable to the subsidiaries and other general corporate expenses utilizing a combination of revenues, property at cost and payroll for the allocation base. Williams Holdings, as a separate corporate entity, does not receive such an allocation because it has no revenues, property or employees. Management believes that the method used for these allocations is reasonable.

New accounting standards

The Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 is effective for fiscal years beginning after June 15, 1999. This standard requires that all derivatives be recognized as assets or liabilities in the balance sheet and that those instruments be measured at fair value. The effect of this standard on Williams Holdings' results of operations and financial position will be evaluated in 1999.

The American Institute of Certified Public Accountants issued Statement of Position (SOP) 98-5, "Reporting on the Costs of Start-Up Activities," effective for fiscal years beginning after December 15, 1998. The SOP requires that all start-up costs be expensed and that the effect of adopting the SOP be reported as the cumulative effect of a change in accounting principle. Williams Holdings will adopt this SOP effective January 1, 1999. The effect of adopting the SOP on Williams Holdings' results of operations and financial position is not expected to be material.

The Emerging Issues Task Force (EITF) reached a consensus on Issue No. 98-10, "Accounting for Contracts Involved in Energy Trading and Risk Management Activities," which is effective for fiscal years beginning after December 15, 1998. The effect of initially applying the Consensus must be reported as a cumulative effect of a change in accounting principle, and financial statements for periods prior to initial application of the Consensus may not be restated. The EITF concluded that energy trading contracts should be recorded at fair value in the balance sheet, with changes in fair value included in earnings. Energy Marketing & Trading records its energy contracts at estimated fair value, except for certain types of contracts that are not currently considered to be trading in nature. The effect of the Consensus on Williams Holdings' results of operations and financial position has yet to be determined.

NOTE 2. ACQUISITIONS

MAPCO

On March 28, 1998, Williams completed the acquisition of MAPCO Inc. by exchanging 1.665 shares of Williams common stock for each outstanding share of MAPCO common stock. In addition, outstanding MAPCO employee stock options were converted into 5.7 million shares of Williams common stock. Upon completion, 98.8 million shares of Williams common stock valued at $3.1 billion, based on the closing price of Williams common stock on March 27, 1998, were issued. Upon completion of the merger, Williams transferred its interest in MAPCO to Williams Holdings, and MAPCO became part of the Energy Services business unit.

The merger constituted a tax-free reorganization and has been accounted for as a pooling of interests. Accordingly, all prior period consolidated financial statements presented include the combined results of operations, financial position and cash flows of MAPCO and Williams Holdings. Intercompany transactions between Williams Holdings and MAPCO prior to the merger have been eliminated, and no material adjustments were necessary to conform MAPCO's accounting policies.

In connection with the merger, Williams Holdings has recognized approximately $72 million in merger-related costs in 1998, comprised primarily of outside professional fees and early retirement and severance costs. Approximately $51 million of these merger-related costs is included in other (income) expense-net as a component of segment profit within Energy Services for 1998 (see Note 19), and approximately $21 million, unrelated to segments, is included in general corporate expenses. During 1997, payments of $32.6 million were made for non-compete agreements. These costs are being amortized over one to three years from the merger completion date.

Nortel

On April 30, 1997, Williams Holdings and Nortel combined their customer-premise equipment sales and service operations into a limited liability company, Williams Communications Solutions, LLC. In addition, Williams Holdings paid $68 million to Nortel. Williams Holdings has accounted for its 70 percent interest in the operations that Nortel contributed to the LLC as a purchase business combination and, beginning May 1, 1997, has included the results of operations of the acquired company in Williams Holdings' Consolidated Statement of Operations. Accordingly, the acquired assets and liabilities, including $168 million in accounts receivable, $68 million in accounts payable and accrued liabilities and $150 million in debt obligations, were recorded based on an allocation of the purchase price, with substantially all of the cost in excess of historical carrying values allocated to goodwill.

Williams Holdings recorded the 30 percent reduction in its operations contributed to the LLC as a sale to the minority shareholder of the LLC. Williams Holdings recognized a gain of $44.5 million based on the excess of the fair value over the net book value (approximately $71 million) of its operations conveyed to the LLC minority interest. Income taxes were not provided on the gain, because the transaction did not affect the difference between the financial and tax bases of identifiable assets and liabilities.

If the transaction occurred on January 1, 1996, Williams Holdings' unaudited pro forma revenues for the years ended 1997 and 1996 would have been $6,768 million and $5,894 million, respectively. The pro forma effect of the transaction on Williams Holdings' net income (loss) is not significant. Pro forma financial information is not necessarily indicative of results of operations that would have occurred if the transaction had occurred on January 1, 1996, or of future results of operations of the combined companies.

NOTE 3. DISCONTINUED OPERATIONS

On September 10, 1996, substantially all of the net assets of the MAPCO coal business were sold to Alliance Coal Corporation, a corporation formed by The Beacon Group Energy Investment Fund, L.P. ("Beacon"), for $236 million in cash. The sale resulted in losses of $14.3 million, $6.3 million and $47.2 million in 1998, 1997 and 1996, respectively (net of income tax benefits of $7.4 million, $.7 million and $30 million, respectively). The losses in 1998 and 1997 include cost accruals for contractual obligations related to financial performance of the assets sold to Beacon and a 1997 income tax adjustment to the 1996 loss amount.

NOTE 5. ASSET SALES, WRITE-OFFS AND OTHER ACCRUALS

Included in the 1998 segment profit for all of the respective business units and general corporate expenses are accruals totaling approximately $23 million related to the modification of Williams' employee benefit program associated with vesting of paid time off.

Included in the 1998 other (income) expense-net and segment profit for Energy Marketing & Trading are asset impairments totaling approximately $14 million related to the decision to focus its retail natural gas and electric business from sales to small commercial and residential customers to large end users. The impairment primarily reflects the reduction in value of a software system and certain intangible assets associated specifically with retail energy applications that will no longer be utilized by Energy Marketing & Trading and for which management estimates the fair value to be insignificant.

Included in the 1998 other (income) expense-net and segment profit for Petroleum Services is a $15.5 million loss provision, including interest, for potential refunds to customers from a recent order from the Federal Energy Regulatory Commission (see Note 17 for additional information).

Included in the 1998 other (income) expense-net in segment costs and expenses and Network Applications' segment loss is a $23.2 million loss related to a venture involved in the technology and transmission of business information for news and educational purposes. The loss occurred as a result of Williams Holdings' re-evaluation and decision to exit the venture as Williams Holdings decided against making further investments in the venture. The loss was recorded in the third quarter, and Williams Holdings abandoned the venture during the fourth quarter. The loss primarily consists of $17 million from impairing the total carrying amount of the investment and $5 million from recognition of contractual obligations that will continue after the abandonment. During the fourth quarter of 1998, $2 million of contractual obligations was paid. Williams Holdings' share of losses from the venture was $3.7 million in 1998 and $2.3 million in 1997.

Included in the 1997 other (income) expense-net in segment costs and expenses and Network Applications' segment loss are impairments and other charges totaling $49.8 million. In the fourth quarter of 1997, Communications made the decision and committed to a plan to sell the learning content business, which resulted in a loss of $28 million. The loss consisted of a $21 million impairment of the assets to fair value less cost to sell and recognition of $7 million in exit costs primarily consisting of employee-related costs and contractual obligations. Fair value was based on management's estimate of the expected net proceeds to be received. During 1998, the learning content business was sold with a resulting $2 million reduction in 1998 expenses. During 1998, $5 million of exit costs was paid. The results of operations and the effect of suspending amortization for the learning content business included in consolidated net income (loss) are not significant for any of the periods presented.

Additionally in the fourth quarter of 1997, Communications' management evaluated certain Network Applications' business activities because of indications that their carrying values may not be recoverable. This resulted in impairments of $17 million, based upon management's estimate as to the ultimate recovery of these evaluated activities.

In 1997, Williams Holdings sold its interest in the natural gas liquids and condensate reserves in the West Panhandle field of Texas for $66 million in cash. The sale resulted in a $66 million pre-tax gain on the transaction because the related reserves had no book value.

In 1996, Williams Holdings recognized a pre-tax gain of $15.7 million from the sale of certain communication rights for approximately $38 million.

Also in 1996, Williams Holdings sold its Iowa propane and liquid fertilizer assets as well as its remaining liquid fertilizer assets in Arkansas, Illinois, Indiana, Minnesota, Ohio and Wisconsin for $43 million in cash, resulting in a pre-tax gain of $20.8 million.

WILLIAMS HOLDINGS OF DELAWARE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Cash refunds for income taxes (net of payments) from Williams and certain federal and state taxing authorities were $3 million in 1998. Cash payments for income taxes (net of refunds) to Williams and certain federal and state taxing authorities were $108 million and $371 million in 1997 and 1996, respectively.

NOTE 7. EXTRAORDINARY LOSS

During 1998, Williams Holdings paid $54.4 million to redeem higher interest rate debt for a $4.8 million net loss (net of a $2.6 million benefit for income taxes).

During 1997, Williams Pipe Line, a subsidiary of Williams Holdings, paid approximately $55 million to redeem $50 million of debt with a stated interest rate of 9.78 percent, resulting in a loss of $3.6 million (net of a $2.4 million benefit for income taxes).

NOTE 8. EMPLOYEE BENEFIT PLANS

Substantially all of Williams Holdings' employees are covered by non-contributory defined-benefit pension plans. Williams Pipe Line and Pekin Energy, subsidiaries of Williams Holdings, have separate plans for their union employees. At December 31, 1997 and 1996, MAPCO had separate plans covering substantially all of its employees including certain employees of the coal business sold in 1996 (see Note 3). During 1998, one of the MAPCO plans merged into a Williams plan, and the other plan transferred to Williams. Effective August 1, 1997, separate plans were established for the Williams Communications Solutions, LLC union employees and the Williams Communications Solutions, LLC salaried employees (LLC plans). Substantially all of the remaining Williams Holdings' employees are covered by Williams' non-contributory defined-benefit pension plans in which Williams Holdings is included. Williams Holdings is also included in Williams' health care plan that provides postretirement medical benefits to certain retired employees. Contributions for pension and postretirement medical benefits related to Williams Holdings' participation in the Williams plans were $10 million in 1998, $3 million in 1997, and $29 million in 1996. The change in contributions from year to year is due to a change in the rate of pension contributions during the periods. Contributions in excess of the minimum funding requirements were made in 1996, and the resulting credit balances were used to reduce the required pension contributions in 1997.

The lease term will include an interim term, during which the covered network assets will be constructed, that is anticipated to end no later than December 31, 1999 and a base term. The interim and base terms are expected to total five years and, if renewed, could total seven years.

Williams Holdings has an option to purchase the covered network assets during the lease term at an amount approximating the lessor's cost. Williams Holdings provides a residual value guarantee, the present value of which is equal to a maximum of 89.9 percent of the cost of the assets under lease. The residual value guarantee is reduced by the present value of actual lease payments. In the event that Williams Holdings does not exercise its purchase option, Williams Holdings expects the fair market value of the covered network assets to substantially reduce Williams Holdings' obligation under the residual value guarantee. Williams Holdings' disclosures for future minimum annual rentals under non-cancelable operating leases do not include amounts for the residual value guarantee. As of December 31, 1998, $287 million of costs have been incurred by the lessor.

NOTE 13. MINORITY INTEREST

During 1998, Williams Holdings formed separate legal entities and contributed various assets to a newly-formed limited partnership, Castle Associates L.P. ("Castle"), as a part of a transaction that generated funds for Williams' and Williams Holdings' general corporate use. An outside investor purchased from Williams Holdings a non-controlling preferred interest in the newly formed entity for $200 million. The assets and liabilities of Castle are consolidated for financial reporting purposes. The outside investor's interest of $200 million is reflected in "Minority interest in consolidated subsidiaries" in the Consolidated Balance Sheet. The transaction did not result in any gain or loss for Williams Holdings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

The preferred interest holders in Castle are entitled to a priority return based on a variable rate structure, currently approximately seven percent, in addition to their participation in the operating results of the partnership.

The Castle limited partnership agreement and associated operating documents included certain restrictive covenants and guarantees of Williams Holdings and certain of its subsidiaries. These restrictions are similar to those in the Williams Holdings' credit agreement and other debt instruments.

NOTE 14. STOCK-BASED COMPENSATION

Williams has several plans providing for common-stock-based awards to its employees and employees of its subsidiaries. The plans permit the granting of various types of awards including, but not limited to, stock options, stock-appreciation rights, restricted stock and deferred stock. Awards may be granted for no consideration other than prior and future services or based on certain financial performance targets being achieved. The purchase price per share for stock options and the grant price for stock-appreciation rights may not be less than the market price of the underlying stock on the date of grant. Depending upon terms of the respective plans, stock options become exercisable after three or five years, subject to accelerated vesting if certain future stock prices or specific financial performance targets are achieved. Stock options expire ten years after grant.

Williams' employee stock-based awards are accounted for under provisions of Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to Employees" and related interpretations. Williams' fixed plan common stock options do not result in compensation expense, because the exercise price of the stock options equals the market price of the underlying stock on the date of grant.

SFAS No. 123, "Accounting for Stock-Based Compensation," requires that companies who continue to apply APB Opinion No. 25 disclose pro forma net income
(loss) assuming that the fair-value method in SFAS No. 123 had been applied in measuring compensation cost. Pro forma net income (loss) for Williams Holdings was $(74.4) million, $261.4 million and $320.5 million for 1998, 1997 and 1996, respectively. Reported net income (loss) was $(29.4) million, $291.1 million and $326.2 million for 1998, 1997 and 1996, respectively. Pro forma amounts for 1998 include the previously unrecognized compensation expense related to the MAPCO options converted at the time of the merger (see Note 2) and the remaining total compensation expense from the awards made in 1997, as these awards fully vested in 1998 as a result of the accelerated vesting provision. Pro forma amounts for 1997 include compensation expense from approximately 65 percent of the awards made in 1996, as these awards fully vested in 1997 as a result of the accelerated vesting provision. Since compensation expense from stock options is recognized over the future years' vesting period for pro forma disclosure purposes, and additional awards generally are made each year, pro forma amounts may not be representative of future years' amounts.

The following summary reflects stock options related to 1998, 1997 and 1996:

                                                              1998    1997    1996

NOTE 15. FINANCIAL INSTRUMENTS

Fair-value methods

The following methods and assumptions were used by Williams Holdings in estimating its fair-value disclosures for financial instruments:

Cash and cash equivalents and notes payable: The carrying amounts reported in the balance sheet approximate fair value due to the short-term maturity of these instruments.

Notes and other non-current receivables: For those notes with interest rates approximating market or maturities of less than three years, fair value is estimated to approximate historically recorded amounts.

Due from parent and long-term debt with affiliates: The amounts bear interest at rates approximating market; therefore, fair value is estimated to approximate historically recorded amounts.

Investment in Williams debentures: The fair value of Williams Holdings' investment is based on the prices of similar securities with similar terms and credit ratings. Williams Holdings used the expertise of an outside investment banking firm to estimate fair value.

Investments-cost, advances to affiliates and other: Fair value is estimated to approximate historically recorded amounts as the operations underlying these investments are in their developmental phases.

Long-term debt: The fair value of Williams Holdings' long-term debt is valued using indicative year-end traded bond market prices for publicly traded issues, while private debt is valued based on the prices of similar securities with similar terms and credit ratings. At December 31, 1998 and 1997, 64 percent and 54 percent, respectively, of Williams Holdings' long-term debt was publicly traded. Williams Holdings used the expertise of an outside investment banking firm to estimate the fair value of long-term debt.

Interest-rate swap: Fair value is determined by discounting estimated future cash flows using forward interest rates derived from the year-end yield curve. Fair value was calculated by the financial institution that is the counterparty to the swap.

Interest-rate locks: Fair value is determined using year-end traded market prices for the referenced U.S. Treasury securities underlying the contracts. Fair value was calculated by the financial institutions that are parties to the locks.

Energy-related trading and hedging: Energy-related trading includes forwards, options, swaps and purchase and sales commitments. Energy-related hedging includes options and swaps. Fair value reflects management's best estimates using valuation techniques that reflect the best information available in the circumstances. This information includes various factors such as quoted market prices, estimates of market prices in absence of quoted market prices, contractual volumes, estimated volumes under option and other arrangements that result in varying volumes, other contract terms, liquidity of the market in which the contract is transacted, credit considerations, time value and volatility factors underlying the positions.

The 1998 average fair value of the energy-related trading assets and liabilities is $485 million and $518 million, respectively. The 1997 average fair value of the energy-related trading assets and liabilities is $258 million and $345 million, respectively.

Off-balance-sheet credit and market risk

Williams Holdings is a participant in the following transactions and arrangements that involve financial instruments that have off-balance-sheet risk of accounting loss. It is not practicable to estimate the fair value of these off-balance-sheet financial instruments because of their unusual nature and unique characteristics.

In 1997, Williams Holdings entered into agreements to sell, on an ongoing basis, certain of their accounts receivables. At December 31, 1998 and 1997, $185 million and $200 million, respectively, have been sold under these agreements.

In connection with the 1995 sale of its network services operations, Williams has been indemnified by LDDS against any losses related to retained guarantees of $113 million and $135 million at December 31, 1998 and 1997, respectively, for lease rental obligations.

Williams Holdings has issued other guarantees and letters of credit with off-balance-sheet risk that total approximately $81 million and $54 million at December 31, 1998 and 1997, respectively. Williams Holdings believes it will not have to perform under these agreements, because the likelihood of default by the primary party is remote and/or because of certain indemnifications received from other third parties.

Energy trading activities

Williams Holdings, through Energy Marketing & Trading, provides price-risk management services associated with the energy industry to its customers. These services are provided through a variety of energy contracts including forward contracts, futures contracts, option contracts, swap agreements and purchase and sale commitments. See Note 1 for a description of the accounting for these trading activities. The net gain from trading activities was $112.6 million, $125.8 million and $99.2 million in 1998, 1997 and 1996, respectively.

Energy Marketing & Trading enters into contracts which involve physical delivery of an energy commodity. Prices under these contracts are both fixed and variable. These contracts involve both firm commitments requiring fixed volumes and option and other arrangements that result in varying volumes. Swap arrangements call for Energy Marketing & Trading to make payments to (or receive payments from) counterparties based upon the differential between a fixed and variable price or variable prices for different locations. Energy Marketing & Trading buys and sells financial option contracts which give the buyer the right to exercise the options and receive the difference between a predetermined strike price and a market price at the date of exercise. The prices used for forwards, swap, option and physical contracts consider exchange quoted prices or management's estimates based on the best information available. Energy Marketing & Trading also enters into futures contracts, which are commitments to either purchase or sell a commodity at a future date for a specified price and are generally settled in cash, but may be settled through delivery of the underlying commodity. The market prices for futures contracts are based on exchange quotations.

Energy Marketing & Trading is subject to market risk from changes in energy commodity market prices, the portfolio position of its financial instruments and physical commitments, the liquidity of the market in which the contract is transacted, and changes in interest rates and credit risk.

Energy Marketing & Trading manages market risk on a portfolio basis through established trading policy guidelines, which are monitored on an ongoing basis. Energy Marketing & Trading attempts to minimize credit-risk exposure to trading counterparties and brokers through formal credit policies and monitoring procedures. In the normal course of business, collateral is not required for financial instruments with credit risk.

The notional quantities for trading activities at December 31 are as follows:

The direct costs charged to Williams Holdings' subsidiaries are reflected in selling, general and administrative expenses, and the direct costs charged to Williams Holdings (parent) related to the MAPCO merger (see Note 2) are reflected in general corporate expenses. Allocated parent company expenses are included in general corporate expenses in the Consolidated Statement of Operations.

Williams Holdings and its subsidiaries maintain promissory notes with Williams for both advances from and advances to Williams depending on the cash position of each subsidiary. Amounts outstanding are payable on demand; however, the net amount outstanding at December 31, 1998, has been classified as long-term as there are no expectations for Williams and Williams Holdings and its subsidiaries to demand payment in the next year. The agreements do not require commitment fees. Interest is payable monthly, and rates vary with market conditions. The interest rates were 5.83 percent and 6.29 percent at December 31, 1998 and 1997, respectively.

Interest accrued includes $22 million in 1998 resulting from advances from Williams. Investing income includes $22 million, $36 million and $31 million for 1998, 1997 and 1996, respectively, resulting from advances to Williams.

During 1998, Williams Holdings utilized advances from other Williams' subsidiaries to repay external debt obligations and to fund additional capital expenditures. The advances are due in 2002, and the interest rate was 5.57 percent at December 31, 1998. The balance at December 31, 1998 was approximately $1 billion including $65.4 million classified as current. Interest accrued in 1998 includes $14.4 million related to these advances.

During 1998, two of Williams Holdings' subsidiaries issued two separate notes totaling $198 million to Williams. The notes are payable on demand, however, amounts outstanding have been classified as long-term as these subsidiaries are not expected to demand payment from Williams within the next year. Interest rates vary with market conditions. The interest rate for these notes at December 31, 1998, was 6.5 percent.

Williams Holdings' subsidiaries have transactions primarily with the following affiliates: Northwest Pipeline, Williams Gas Pipelines Central, Transcontinental Gas Pipe Line and Texas Gas. Energy Marketing & Trading's revenues include natural gas sales to affiliates of $332 million, $429 million and $499 million for 1998, 1997 and 1996, respectively. Energy Marketing & Trading also incurred costs and operating expenses, including transportation and certain other costs, from affiliates of $93 million, $96 million and $157 million for 1998, 1997 and 1996, respectively. These sales and costs are included in Energy Marketing & Trading revenues consistent with a "net" basis of reporting these activities. Transactions with affiliates are at prices that generally apply to unaffiliated parties.

NOTE 17. CONTINGENT LIABILITIES AND COMMITMENTS

Rate and regulatory matters

Williams Pipe Line (WPL) has various regulatory proceedings pending. On July 15, 1998, WPL received an Order from the Federal Energy Regulatory Commission (FERC) which affirmed an administrative law judge's 1996 initial decision regarding rate-making proceedings for the period September 15, 1990 through May 1, 1992. The FERC has ruled that WPL did not meet its burden of establishing that its transportation rates in its 12 noncompetitive markets were just and reasonable for the period and has ordered refunds. WPL continues to believe it should prevail upon appeal regarding collected rates for that period. However, due to this FERC decision, WPL accrued $15.5 million, including interest, in the second quarter of 1998, for potential refunds to customers for the issues described above. Since May 1, 1992, WPL has collected and recognized as revenues $151 million in noncompetitive markets that are in excess of tariff rates previously approved by the FERC and that are subject to refund with interest. WPL believes that the tariff rates collected in these markets during this period will be justified in accordance with the FERC's cost-basis guidelines and will be making the appropriate filings with the FERC to support this position.

Environmental matters

Certain Williams Holdings' subsidiaries have been identified as potentially responsible parties (PRP) at various Superfund and state waste disposal sites. In addition, these subsidiaries have incurred, or are alleged to have incurred, various other hazardous materials removal or remediation obligations under environmental laws. Although no assurances can be given, Williams Holdings does not believe that the PRP status of these subsidiaries will have a material adverse effect on its financial position, results of operations or net cash flows.

The Midstream Gas & Liquids unit of Energy Services (WES) had recorded an aggregate liability of approximately $10 million, representing the current estimate of future environmental and remediation costs. WES also accrues environmental remediation costs for its petroleum products pipeline, retail petroleum, refining and propane marketing operations primarily related to soil and groundwater contamination. At December 31, 1998, WES and its subsidiaries had reserves, in addition to other reserves listed above, totaling approximately $31 million. WES recognizes receivables related to environmental remediation costs from state funds as a result of laws permitting states to reimburse certain expenses associated with underground storage tank problems and repairs. At December 31, 1998, WES and its subsidiaries had receivables totaling $14 million. Actual costs incurred will depend on the actual number of contaminated sites identified, the actual amount and extent of contamination discovered, the final cleanup standards mandated by the EPA and other governmental authorities and other factors.

Other legal matters

In 1998, certain royalty owners in a producing field in Cameron Parish, Louisiana, brought suit against a Williams Holdings subsidiary and other working interest owners seeking additional royalties or lease cancellation. An amended petition later added a second Williams Holdings subsidiary, Williams and additional working interest owners. All other defendants have been dismissed or have settled with plaintiffs. In their recently amended damage claim, the plaintiffs asserted royalty underpayments plus interest of approximately $12 million. The claimed damages are attributable to all working interests for a period of about 15 years. One of the two Williams Holdings subsidiaries sued owned a one-half interest in the field and served as operator for approximately eight years. The other subsidiary purchased produced gas from the field. Plaintiffs also request punitive damages equal to double the alleged damages and attorneys' fees. Williams Holdings believes all royalties due from its subsidiaries were properly paid, that the field was properly operated, and that it is not responsible for any amounts due from any other working interests or for the period after its subsidiary had sold its interest and terminated its status as operator of the field. The litigation pending in Cameron Parish, Louisiana, has recently been settled for payments aggregating approximately $9 million, for which reserves have been fully accrued.

On April 7, 1992, a liquefied petroleum gas explosion occurred near an underground salt dome storage facility located near Brenham, Texas and owned by an affiliate of MAPCO Inc., Seminole Pipeline Company ("Seminole"). MAPCO Inc., as well as Seminole, Mid-America Pipeline Company, MAPCO Natural Gas Liquids Inc., and other non-MAPCO entities were named as defendants in civil action lawsuits filed in state district courts located in four Texas counties. Seminole and the above-mentioned subsidiaries of MAPCO Inc. have settled in excess of 1,600 claims in these lawsuits. The only lawsuit remaining is the Dallmeyer case which was tried before a jury in Harris County. In Dallmeyer, the judgment rendered in March 1996 against defendants Seminole and MAPCO Inc. and its subsidiaries totaled approximately $72 million which included nearly $65 million of punitive damages awarded to the 21 plaintiffs. Both plaintiffs and defendants have appealed the Dallmeyer judgment to the Court of Appeals for the Fourteenth District of Texas in Harris County. The defendants seek to have the judgment modified in many respects, including the elimination of punitive damages as well as a portion of the actual damages awarded. If the defendants prevail on appeal, it will result in an award significantly less than the judgment. The plaintiffs have cross-appealed and seek to modify the judgment to increase the total award plus interest to exceed $155 million. In February and March 1998, the defendants entered into settlement agreements involving 17 of the 21 plaintiffs to finally resolve their claims against all defendants for an aggregate payment of approximately $10 million. These settlements have satisfied and reduced the judgment on appeal by approximately $42 million. As to the remaining four plaintiffs, the Court of Appeals issued its decision on October 15, 1998, which, while denying all of the plaintiffs' cross-appeal issues, affirmed in part and reversed in part the trial court's judgment. The defendants had entered into settlement agreements with the remaining plaintiffs which, in light of the decision, Williams Holdings believes will provide for aggregate payments of approximately $13.6 million, the full amount of which has been previously accrued.

In 1991, the Southern Ute Indian Tribe (the Tribe) filed a lawsuit against Williams Production Company (Williams Production), a wholly owned subsidiary of Williams Holdings, and other gas producers in the San Juan Basin area, alleging that certain coal strata were reserved by the United States for the benefit of the Tribe and that the extraction of coal-seam gas from the coal strata was wrongful. The Tribe seeks compensation for the value of the coal-seam gas. The Tribe also seeks an order transferring to the Tribe ownership of all of the defendants' equipment and facilities utilized in the extraction of the coal-seam gas. In September 1994, the court granted summary judgment in favor of the defendants, and the Tribe lodged an interlocutory appeal with the U.S. Court of Appeals for the Tenth Circuit. Williams Production agreed to indemnify the Williams Coal Seam Gas Royalty Trust (Trust) against any losses that may arise in respect of certain properties subject to the lawsuit. On July 16, 1997, the U.S. Court of Appeals for the Tenth Circuit reversed the decision of the district court, held that the Tribe owns the coal-seam gas produced from certain coal strata on fee lands within

the exterior boundaries of the Tribe's reservation, and remanded the case to the district court for further proceedings. On September 16, 1997, Amoco Production Company, the class representative for the defendant class (of which Williams Production is a part), filed its motion for rehearing en banc before the Court of Appeals. On July 20, 1998, the Court of Appeals sitting en banc affirmed the panel's decision. The Supreme Court has granted a writ of certiorari in respect of this decision.

Williams Communications, Inc. filed suit on March 20, 1998, against WorldCom Network Services, Inc. (WorldCom) in district court in Tulsa County in order to prevent WorldCom from disconnecting any Williams' equipment on the WorldCom network. This suit sought a declaratory judgment that the single fiber retained by Williams Holdings on the WorldCom network could be used for specified multimedia uses, and that WorldCom was required to permit Williams Holdings to purchase additional fiber either acquired or constructed by WorldCom. WorldCom had denied Williams Holdings' claim and had asserted various counterclaims for monetary damages, rescission and injunctive relief. This lawsuit was settled on July 9, 1998. The settlement resolves all claims for monetary damages, permitted uses of Williams Holdings' fiber on the WorldCom network and Williams Holdings' right to purchase additional fiber on WorldCom fiber builds. There was no significant financial impact to Williams Holdings as a result of the settlement.

In connection with agreements to resolve take-or-pay and other contract claims and to amend gas purchase contracts, Transcontinental Gas Pipe Line and Texas Gas each entered into certain settlements with producers which may require the indemnification of certain claims for additional royalties which the producers may be required to pay as a result of such settlements. Transco Energy Company and Transco Gas Supply Company (wholly owned subsidiaries of Williams Holdings) have also been named as defendants in certain of these lawsuits. As a result of such settlements, Transcontinental Gas Pipe Line is currently defending two lawsuits brought by producers. In one of the cases, a jury verdict found that Transcontinental Gas Pipe Line was required to pay a producer damages of $23.3 million including $3.8 million in attorneys' fees. Transcontinental Gas Pipe Line is pursuing an appeal. In the other case, a producer has asserted damages, including interest calculated through December 31, 1997, of approximately $6 million. Producers have received and may receive other demands, which could result in additional claims. Indemnification for royalties will depend on, among other things, the specific lease provisions between the producer and the lessor and the terms of the settlement between the producer and either Transcontinental Gas Pipe Line or Texas Gas. Texas Gas may file to recover 75 percent of any such additional amounts it may be required to pay pursuant to indemnities for royalties under the provisions of FERC Order 528.

In connection with the sale of certain coal assets in 1996, MAPCO entered into a Letter Agreement with the buyer providing for indemnification by MAPCO for reductions in the price or tonnage of coal delivered under a certain pre-existing Coal Sales Agreement dated December 1, 1986. The Letter Agreement is effective for reductions during the period July 1, 1996, through December 31, 2002, and provides for indemnification for such reductions as incurred on a quarterly basis. The buyer has stated it is entitled to indemnification from MAPCO for amounts of $7.8 million through June 30, 1998, and may claim indemnification for additional amounts in the future. MAPCO has filed for declaratory relief as to certain aspects of the buyer's claims. MAPCO also believes it would be entitled to substantial set-offs and credits against any amounts determined to be due and has accrued a liability representing an estimate of amounts it expects to incur in satisfaction of this indemnity. The parties are currently pursuing settlement negotiations as part of a mediation.

In 1998, the United States Department of Justice informed Williams Holdings that Jack Grynberg, an individual, had filed claims in the United States District Court for the District of Colorado under the False Claims Act against Williams Holdings and certain of its wholly owned subsidiaries including Williams Field Services Company and Williams Production Company. Mr. Grynberg has also filed claims against approximately 300 other energy companies and alleges that the defendants violated the False Claims Act in connection with the measurement and purchase of hydrocarbons. The relief sought is an unspecified amount

of royalties allegedly not paid to the federal government, treble damages, a civil penalty, attorneys' fees, and costs.

In addition to the foregoing, various other proceedings are pending against Williams Holdings or its subsidiaries which are incidental to their operations.

Summary

While no assurances may be given, Williams Holdings does not believe that the ultimate resolution of the foregoing matters, taken as a whole and after consideration of amounts accrued, insurance coverage or other indemnification arrangements, will have a materially adverse effect upon Williams Holdings' future financial position, results of operations or cash flow requirements.

Other matters

During the second quarter of 1998, Energy Marketing & Trading entered into a 15-year contract giving Williams Holdings the right to receive fuel conversion services for purposes of generating electricity. This contract also gives Williams Holdings the right to receive installed capacity and certain ancillary services. Annual committed payments under the contract range from $140 million to $165 million, resulting in total committed payments of approximately $2.3 billion.

depreciation, depletion and amortization. The accounting policies of the segments are the same as those described in Note 1, Summary of Significant Accounting Policies. Intersegment sales are generally accounted for as if the sales were to unaffiliated third parties, that is, at current market prices.

Williams Holdings' reportable segments are strategic business units that offer different products and services. The segments are managed separately because each segment requires different technology, marketing strategies and industry knowledge. Other includes investments in international energy and communications-related ventures, as well as corporate operations.

The following table reflects the reconciliation of segment profit, per the table on the following page, to operating income as reported on the Consolidated Statement of Operations.

(ii) the Borrower may not select Eurodollar Rate Advances for any Borrowing if the aggregate amount of such Borrowing is less than $20,000,000;

(iii) if the Majority Banks shall notify the Agent that either (A) the Eurodollar Rate for any Interest Period for any Eurodollar Rate Advances will not adequately reflect the cost to such Banks of making or funding their respective Eurodollar Rate Advances for such Interest Period, or (B) that U.S. dollar deposits for the relevant amounts and Interest Period for their respective Advances are not available to them in the London interbank market, or it is otherwise impossible to have Eurodollar Rate Advances, the Agent shall forthwith so notify the Borrower and the Banks, whereupon (I) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (II) the obligations of the Banks to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent, at the request of the Majority Banks, shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and, except as provided in Section 2.2(b)(v), each Advance comprising any requested A Borrowing shall be a Base Rate Advance;

(iv) if the Agent is unable to determine the Eurodollar Rate for Eurodollar Rate Advances, the obligation of the Banks to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and, except as provided in Section 2.2(b)(v), each Advance comprising any requested A Borrowing shall be a Base Rate Advance; and

(v) if the Borrower has requested a proposed A Borrowing consisting of Eurodollar Rate Advances and as a result of circumstances referred to in Section 2.2(b)(iii) or (iv) such A Borrowing would not consist of Eurodollar Rate Advances, the Borrower may, by notice given not later than 3:00 P.M.

(c) Each Notice of A Borrowing shall be irrevocable and binding on the Borrower, except as set forth in Section 2.2(b)(v). In the case of any A Borrowing which the related Notice of A Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Bank against any loss, cost or expense incurred by such Bank as a result of any failure to fulfill on or before the date specified in such Notice of A Borrowing for such A Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (including loss of reasonably anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund the A Advance to be made by such Bank as part of such A Borrowing when such A Advance, as a result of such failure, is not made on such date. A certificate in reasonable detail as to the basis for and the amount of such loss, cost or expense submitted to the Borrower and the Agent by such Bank shall be prima facie evidence

A certificate in reasonable detail as to the basis for and the amount of such loss, cost or expense submitted to the Borrower and the Agent by such Bank shall be prima facie evidence of the amount of such loss, cost or expense.

(d) Unless the Agent shall have received notice from a Bank prior to the date of any A Borrowing that such Bank will not make available to the Agent such Bank's ratable portion of such A Borrowing, the Agent may assume that such Bank has made such portion available to the Agent on the date of such A Borrowing in accordance with subsection (a) of this Section 2.2 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made such ratable portion available to the Agent, such Bank and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to A Advances comprising such A Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank's A Advance as part of such A Borrowing for purposes of this Agreement.

(e) The failure of any Bank to make the A Advance to be made by it as part of any A Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its A Advance on the date of such A Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the A Advance to be made by such other Bank on the date of any A Borrowing.

(b) If any Bank determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Bank or any corporation controlling such Bank and that the amount of such capital is increased by or based upon the existence of such Bank's commitment to lend to the Borrower hereunder and other commitments of this type, then, upon demand by such Bank (with a copy of such demand to the Agent), the Borrower shall immediately pay to the Agent for the account of such Bank, from time to time as specified by such Bank, additional amounts sufficient to compensate such Bank or such corporation in the light of such circumstances, to the extent that such Bank reasonably determines such increase in capital to be allocable to the existence of such Bank's commitment to lend hereunder. A certificate as to the amount of such additional amounts, submitted to the Borrower and the Agent by such Bank, shall be prima facie evidence of the amount of such additional amounts. No Bank shall have any right to recover any additional amounts under this Section 2.11(b) for any period more than 90 days prior to the date such Bank notifies the Borrower of any such compliance.

(c) In the event that any Bank makes a demand for payment under
Section 2.7 or this Section 2.11, the Borrower may within ninety (90) days of such demand, if no Event of Default or event which, with the giving of notice or lapse of time or both, would constitute an Event of Default then exists, replace such Bank with another commercial bank in accordance with all of the provisions of the last sentence of Section 8.6(a) (including execution of an appropriate Transfer Agreement); provided that (i) all obligations of such Bank to lend hereunder shall be terminated and

18

the Notes payable to such Bank and all other obligations owed to such Bank hereunder shall be purchased in full without recourse at par plus accrued interest at or prior to such replacement, (ii) such replacement bank shall be reasonably satisfactory to the Agent and the Majority Banks, (iii) such replacement bank shall, from and after such replacement, be deemed for all purposes to be a "Bank" hereunder with a Commitment in the amount of the Commitment of such Bank immediately prior to such replacement (plus, if such replacement bank is already a Bank prior to such replacement the respective Commitment of such Bank to the Borrower prior to such replacement), as such amount may be changed from time to time pursuant hereto, and shall have all of the rights, duties and obligations hereunder of the Bank being replaced, and
(iv) such other actions shall be taken by the Borrower, such Bank and such replacement bank as may be appropriate to effect the replacement of such Bank with such replacement bank on terms such that such replacement bank has all of the rights, duties and obligations hereunder as such Bank (including, without limitation, execution and delivery of new Notes to such replacement bank, redelivery to the Borrower in due course of the Notes of the Borrower payable to such Bank and specification of the information contemplated by Schedule I as to such replacement bank).

Section 2.12 Illegality. Notwithstanding any other provision of this Agreement, if any Bank shall notify the Agent that the introduction of or any change in or in the interpretation of any law or regulation shall make it unlawful, or that any central bank or other governmental authority shall assert that it is unlawful, for any Bank or its Eurodollar Lending Office to perform its obligations hereunder to make, or Convert a Base Rate Advance into, a Eurodollar Rate Advance or to continue to fund or maintain any Eurodollar Rate Advance, then, on notice thereof to the Borrower by the Agent, (i) the obligation of each of the Banks to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent, at the request of the Majority Banks, shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and (ii) the Borrower shall forthwith prepay in full all Eurodollar Rate Advances of all Banks then outstanding together with all accrued interest thereon and all amounts payable pursuant to Section 8.4(b), unless each Bank shall determine in good faith in its sole opinion that it is lawful to maintain the Eurodollar Rate Advances made by such Bank to the end of the respective Interest Periods then applicable thereto or unless the Borrower, within five Business Days of notice from the Agent, Convert all Eurodollar Rate Advances of all Banks then outstanding into Base Rate Advances in accordance with Section 2.19.

Section 2.13 Payments and Computations.

(a) The Borrower shall make each payment hereunder and under the Notes to be made by it not later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars to the Agent at its New York address referred to in Section 8.2 in same day funds, without deduction, counterclaim or offset of any kind. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or commitment fees ratably (other than amounts payable pursuant to Section 2.7, 2.11, 2.14, 2.16 or 8.4(b)) to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank to such Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. In no event shall any Bank be entitled

19

to share any fee paid to the Agent pursuant to Section 2.3(b), any auction fee paid to the Agent pursuant to Section 2.16(a)(i) or any other fee paid to the Agent, as such.

(b) The Borrower hereby authorizes each Bank, if and to the extent payment owed to such Bank by the Borrower is not made when due hereunder or under any Note held by such Bank, to charge from time to time against any or all of the Borrower's accounts with such Bank any amount so due.

(c) (i) All computations of interest based on clause (a) or clause (b) of the definition herein of Base Rate and of commitment fees shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and
(ii) all computations of interest based on the Eurodollar Rate, the Federal Funds Rate or clause (c) of the definition herein of Base Rate shall be made by the Agent, and all computations of interest pursuant to Section 2.7 shall be made by a Bank, on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or commitment fees are payable. Each determination by the Agent (or, in the case of Section 2.7, by a Bank) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment fee, as the case may be; provided, however, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due by the Borrower to any Bank hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank hereunder. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at the Federal Funds Rate.

Section 2.14 Taxes.

(a) Any and all payments by the Borrower hereunder or under the Notes shall be made, in accordance with Section 2.13, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings with respect thereto, and all liabilities with respect thereto, excluding in the case of each Bank and the Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Bank or the Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction

20

of such Bank's Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14) such Bank or the Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made by the Borrower hereunder or under the Notes executed by it or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or such Notes (hereinafter referred to as "Other Taxes").

(c) The Borrower will indemnify each Bank and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.14) owed and paid by such Bank or the Agent, as the case may be, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Bank or the Agent, as the case may be, makes written demand therefore.

(d) Within 30 days after the date of the payment of Taxes by or at the direction of the Borrower, the Borrower will furnish to the Agent, at its address referred to in Section 8.2, the original or a certified copy of a receipt evidencing payment thereof. Should any Bank or the Agent ever receive any refund, credit or deduction from any taxing authority to which such Bank or the Agent would not be entitled but for the payment by the Borrower of Taxes as required by this Section 2.14 (it being understood that the decision as to whether or not to claim, and if claimed, as to the amount of any such refund, credit or deduction shall be made by such Bank or the Agent, as the case may be, in its sole discretion), such Bank or the Agent, as the case may be, thereupon shall repay to the Borrower an amount with respect to such refund, credit or deduction equal to any net reduction in taxes actually obtained by such Bank or the Agent, as the case may be, and determined by such Bank or the Agent, as the case may be, to be attributable to such refund, credit or deduction.

(e) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.14 shall survive the payment in full of principal and interest hereunder and under the Notes.

Section 2.15 Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary or involuntary, or through the exercise of any right of set-off or otherwise) on account of the A Advances made by it (other than pursuant to Section 2.7, 2.11, 2.14 or 8.4(b)) in excess of its ratable share of payments on account of the A Advances obtained by all the Banks, such Bank shall

21

forthwith purchase from the other Banks such participations in the A Advances owed to them as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them, provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, such purchase from each Bank shall be rescinded and such Bank shall repay to the purchasing Bank the purchase price to the extent of such Bank's ratable share (according to the proportion of (i) the amount of the participation purchased from such Bank as a result of such excess payment to (ii) the total amount of such excess payment) of such recovery together with an amount equal to such Bank's ratable share (according to the proportion of (i) the amount of such Bank's required repayment to (ii) the total amount so recovered from the purchasing Bank) of any interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.15 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation.

Section 2.16 The B Advances.

(a) Each Bank severally agrees that the Borrower may make B Borrowings under this Section 2.16 from time to time on any Business Day during the period from the date hereof until the earlier of (1) the Termination Date or (2) the date occurring thirty (30) days prior to the Stated Termination Date in the manner set forth below; provided that, following the making of each B Borrowing, the aggregate amount of the Advances then outstanding to the Borrower shall not exceed the aggregate amount of the Commitments of the Banks (computed without regard to any B Reduction).

(i) The Borrower may request a B Borrowing under this Section 2.16 by delivering to the Agent, by telecopier, telex or cable, confirmed immediately in writing, a notice of a B Borrowing (a "Notice of B Borrowing"), in substantially the form of Exhibit B-2 hereto, specifying the date and aggregate amount of the proposed B Borrowing, the maturity date for repayment of each B Advance to be made as part of such B Borrowing (which maturity date may not be earlier than the date occurring 14 days after the date of such B Borrowing or later than the earlier of (x) 6 months after the date of such B Borrowing or
(y) the Stated Termination Date), the interest payment date or dates relating thereto, and any other terms to be applicable to such B Borrowing (including, without limitation, the basis to be used by the Banks in determining the rate or rates of interest to be offered by them as provided in paragraph (ii) below and prepayment terms, if any, but excluding any waiver or other modification to any of the conditions set forth in Article III), not later than 10:00 A.M. (New York City time) (A) at least one (1) Business Day prior to the date of the proposed B Borrowing, if the Borrower shall specify in the Notice of B Borrowing that the rates of interest to be offered by the Banks shall be fixed rates per annum and (B) at least five (5) Business Days prior to the date of the proposed B Borrowing, if the Borrower shall instead specify in the Notice of B Borrowing the basis to be used by the Banks in determining the rates of interest to be offered by them. The Agent shall in turn promptly notify each Bank of each request for a B Borrowing received by it from the Borrower by sending such Bank

22

a copy of the related Notice of B Borrowing. Each time that the Borrower gives a Notice of B Borrowing, the Borrower shall pay to the Agent an auction fee equal to $2000.

(ii) Each Bank may, if in its sole discretion it elects to do so, irrevocably offer to make one or more B Advances to the Borrower as part of such proposed B Borrowing at a rate or rates of interest specified by such Bank in its sole discretion, by notifying the Agent (which shall give prompt notice thereof to the Borrower), before 10:00
A.M. (New York City time) (x) on the date of such proposed B Borrowing, in the case of a Notice of B Borrowing delivered pursuant to clause (A) of paragraph (i) above, and (y) three Business Days before the date of such proposed B Borrowing in the case of a Notice of B Borrowing delivered pursuant to clause (B) of paragraph (i) above, of the minimum amount and maximum amount of each B Advance which such Bank would be willing to make as part of such proposed B Borrowing (which amounts may, subject to the proviso to the first sentence of this Section 2.16(a), exceed such Bank's Commitment to the Borrower), the rate or rates of interest therefor and such Bank's Applicable Lending Office with respect to such B Advance; provided that if the Agent in its capacity as a Bank shall, in its sole discretion, elect to make any such offer, it shall notify the Borrower of such offer before 9:45 A.M. (New York City time) on the date on which notice of such election is to be given to the Agent by the other Banks. If any Bank shall elect not to make such an offer, such Bank shall so notify the Agent, before 10:00 A.M. (New York City time) on the date on which notice of such election is to be given to the Agent by the other Banks, and such Bank shall not be obligated to, and shall not, make any B Advance as part of such B Borrowing; provided that the failure by any Bank to give such notice shall not cause such Bank to be obligated to make any B Advance as part of such proposed B Borrowing.

(iii) The Borrower shall, in turn, before 11:00 A.M. (New York City time) (x) on the date of such proposed B Borrowing in the case of a Notice of B Borrowing delivered pursuant to clause (A) of paragraph (i) above and (y) three Business Days before the date of such proposed B Borrowing in the case of a Notice of B Borrowing delivered pursuant to clause (B) of paragraph (i) above, either

(A) cancel such B Borrowing by giving the Agent notice to that effect, or

(B) accept one or more of the offers made by any Bank or Banks pursuant to paragraph (ii) above, in order of the lowest to highest rates of interest or margins (or, if two or more Banks bid at the same rates of interest, and the amount of accepted offers is less than the aggregate amount of such offers, the amount to be borrowed from such Banks as part of such B Borrowing shall be allocated among such Banks pro rata on the basis of the maximum amount offered by such Banks at such rates or margin in connection with such B Borrowing), in any aggregate amount up to the aggregate amount initially requested by the Borrower in the relevant Notice of B Borrowing, by giving notice to the Agent of the amount of each B Advance (which amount shall be equal to or greater than the minimum amount, and equal to or less than the maximum amount, notified to the Borrower by the Agent on behalf of such Bank for such B Advance pursuant to paragraph ii above) to be made by each

23

Bank as part of such B Borrowing, and reject any remaining offers made by Banks pursuant to paragraph (ii) above by giving the Agent notice to that effect.

(iv) If the Borrower notifies the Agent that such B Borrowing is canceled pursuant to paragraph (iii)(A) above, the Agent shall give prompt notice thereof to the Banks and such B Borrowing shall not be made.

(v) If the Borrower accepts one or more of the offers made by any Bank or Banks pursuant to paragraph (iii)(B) above, the Agent shall in turn promptly notify (A) each Bank that has made an offer as described in paragraph (ii) above, of the date and aggregate amount of such B Borrowing and whether or not any offer or offers made by such Bank pursuant to paragraph (ii) above have been accepted by the Borrower, (B) each Bank that is to make a B Advance as part of such B Borrowing, of the amount of each B Advance to be made by such Bank as part of such B Borrowing, and (C) each Bank that is to make a B Advance as part of such B Borrowing, upon receipt, that the Agent has received forms of documents appearing to fulfill the applicable conditions set forth in Article III. Each Bank that is to make a B Advance as part of such B Borrowing shall, before 12:00 noon (New York City time) on the date of such B Borrowing specified in the notice received from the Agent pursuant to clause (A) of the preceding sentence or any later time when such Bank shall have received notice from the Agent pursuant to clause (C) of the preceding sentence, make available for the account of its Applicable Lending Office to the Agent at its New York address referred to in Section 8.2 such Bank's portion of such B Borrowing, in same day funds. Upon fulfillment of the applicable conditions set forth in Article III and after receipt by the Agent of such funds, the Agent will make such funds available to the Borrower at the Agents aforesaid address. Promptly after each B Borrowing the Agent will notify each Bank of the amount of the B Borrowing, the consequent B Reduction and the dates upon which such B Reduction commenced and will terminate.

(b) Each B Borrowing shall be in an aggregate amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof. The Borrower agrees that it will not request a B Borrowing unless, upon the making of such B Borrowing, the limitations set forth in the proviso to the first sentence of Section 2.16(a) are complied with.

(c) Within the limits and on the conditions set forth in this Section 2.16, the Borrower may from time to time borrow under this Section 2.16, repay or prepay pursuant to subsection (d) below, and reborrow under this Section 2.16; provided that a B Borrowing shall not be made by the Borrower within three Business Days of the date of another B Borrowing.

(d) The Borrower shall repay to the Agent for the account of each Bank which has made a B Advance to the Borrower, or each other holder of a B Note of the Borrower, on the maturity date of each B Advance made to the Borrower (such maturity date being that specified by the Borrower for repayment of such B Advance in the related Notice of B Borrowing delivered pursuant to subsection
(a)(i) above and provided in the B Note evidencing such B Advance) the then unpaid principal amount of such B Advance. The Borrower shall not have any right to prepay any principal

24

amount of any B Advance unless, and then only on the terms specified by the Borrower for such B Advance in the related Notice of B Borrowing delivered pursuant to subsection (a)(i) above and set forth in the B Note evidencing such B Advance.

(e) The Borrower shall pay interest on the unpaid principal amount of each B Advance made to the Borrower from the date of such B Advance to the date the principal amount of such B Advance is repaid in full, at the rate of interest for such B Advance specified by the Bank making such B Advance in its notice with respect thereto delivered pursuant to subsection (a)(ii) above, payable on the interest payment date or dates specified by the Borrower for such B Advance in the related Notice of B Borrowing delivered pursuant to subsection (a)(i) above, as provided in the B Note evidencing such B Advance.

(f) The indebtedness of the Borrower resulting from each B Advance made to the Borrower as part of a B Borrowing shall be evidenced by a separate B Note of the Borrower payable to the order of the Bank making such B Advance.

(g) The failure of any Bank to make the B Advance to be made by it as part of any B Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its B Advance on the date of such B Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the B Advance to be made by such other Bank on the date of any B Borrowing.

Section 2.17 Optional Termination. Notwithstanding anything to the contrary in this Agreement, if (i) any Person (other than a trustee or other fiduciary holding securities under an employee benefit plan of TWC or of any Subsidiary of TWC) or two or more Persons acting in concert (other than any group of employees of TWC or of any of its Subsidiaries) shall have acquired beneficial ownership (within the meaning of Rule l3d-3 of the Securities and Exchange Commission under the Securities Exchange Act of 1934), directly or indirectly, of securities of TWC (or other securities convertible into such securities) representing 20% or more of the combined voting power of all securities of TWC entitled to vote in the election of directors, other than securities having such power only by reason of the happening of a contingency, or (ii) during any period of up to 24 consecutive months, commencing before or after the date of this Agreement, individuals who at the beginning of such 24-month period were directors of TWC or who were elected by individuals who at the beginning of such period were such directors or by individuals elected in accordance with this clause (ii) shall cease for any reason to constitute a majority of the board of directors of TWC, or (iii) any Person (other than TWC or a Wholly-Owned Subsidiary of TWC) or two or more Persons acting in concert shall have acquired by contract or otherwise, or shall have entered into a contract or arrangement which upon consummation will result in its or their acquisition of, the power to exercise, directly or indirectly, a controlling influence over the management or policies of the Borrower; then the Agent shall at the request, or may with the consent, of the holders of at least 66-2/3% in principal amount of the A Notes then outstanding or, if no A Notes are then outstanding, Banks having at least 66-2/3% of the Commitments, by notice to the Borrower, declare all of the Commitments and the obligation of each Bank to make Advances to be terminated, whereupon all of the Commitments and each such obligation shall forthwith terminate, and the Borrower shall not have any further right to borrow hereunder.

25

Section 2.18 Extension of Termination Date. By notice given to the Agent and the Banks, at least thirty days but not more than forty-five days before January 1 of any year after 1999, the Borrower may request the Banks to extend the Stated Termination Date for an additional period to a date which is 364 days after the then current Stated Termination Date. Within thirty days after receipt of such request, each Bank that agrees, in its sole and absolute discretion, to so extend the Stated Termination Date shall notify the Borrower and the Agent that it so agrees, and if all Banks so agree the Stated Termination Date shall be so extended.

Section 2.19 Voluntary Conversion of Advances. The Borrower may on any Business Day, if no Event of Default then exists, upon notice (which shall be irrevocable) given to the Agent not later than 11:00 A.M. (x) in the case of a proposed Conversion into Eurodollar Rate Advances, on the third Business Day prior to the date of the proposed conversion, and (y) in the case of a proposed Conversion into Base Rate Advances, on the date of the proposed Conversion, and subject to the provisions of Sections 2.2 and 2.12, Convert all Advances of one Type comprising the same A Borrowing into Advances of the other Type; provided that (i) no Conversion of any Eurodollar Rate Advances shall occur on a day other than the last day of an Interest Period for such Eurodollar Rate Advances, except as contemplated by Section 2.12, and (ii) Advances may not be Converted into Eurodollar Rate Advances if the aggregate unpaid principal amount of the Advances is less than $20,000,000. Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the A Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the Interest Period for each such Advance.

Section 2.20 Automatic Provisions.

Without limitation of the foregoing, each Bank agrees to reimburse the Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, any Note or this Agreement to the extent that the Agent is not reimbursed for such expenses by the Borrower.

Section 7.6 Successor Agent. The Agent may resign at any time as Agent under this Agreement by giving written notice thereof to the Banks and the Borrower and may be removed at any time with or without cause by the Majority Banks.

45

such Bank shall remain responsible for the performance thereof, (iii) such Bank shall remain the holder of any such Note or Notes for all purposes under this Agreement, and (iv) the Borrower, the other Banks and the Agent shall continue to deal solely with and directly with such Bank in connection with such Bank's rights and obligations under this Agreement; and (2) no Bank shall assign or grant a participation that conveys to the assignee or participant the right to vote or consent under this Agreement, other than the right to vote upon or consent to (i) any increase in the amount of any Commitment of such Bank; (ii) any reduction of the principal amount of, or interest to be paid on, such Bank's Advance or Advances or Note or Notes; (iii) any reduction of any fee or other amount payable hereunder to such Bank; or (iv) any postponement of any date fixed for any payment of principal of, or interest on, such Bank's Advance or Advances or Note or Notes or any fee or other amount payable hereunder to such Bank.

46

part of each A Advance to the Borrower equal to the amount of such Advance multiplied by a fraction, the numerator of which is the amount of such portion of such assigning Bank's Commitment so assumed and the denominator of which is the amount of the Commitment of such assigning Bank (without giving effect to any B Reduction) immediately prior to such assumption, shall be transferred to such assignee and evidenced by such assignee's A Note from the Borrower, and the balance of such A Advance shall be evidenced by such assigning Bank's new A Note from the Borrower delivered pursuant to clause (iv)(b) of this sentence;
(vii) if such assignee is not a "Bank" hereunder prior to such assignment, such assignee shall become a party to this Agreement as a Bank and shall be deemed to be a "Bank" hereunder and the amount of all or such portion, as the case may be, of the Commitment so assumed shall be deemed to be the amount set opposite such assigning Bank's name on Schedule IV for purposes of this Agreement and
(viii) if such assignee is not a Bank hereunder prior to such assignment, such assignee shall be deemed to have specified the offices of such assignee named in the respective Transfer Agreement as its "Domestic Lending Office" and "Eurodollar Lending Office" for all purposes of this Agreement and to have specified for purposes of Section 8.2 the notice information set forth in such Transfer Agreement; and the Agent shall promptly after execution of any Transfer Agreement by the Agent and the other parties thereto notify the Banks of the parties to such Transfer Agreement and the amounts of the assigning Bank's Commitment assumed thereby.

(b) If the Borrower does not consent to a proposed assignment by a Bank pursuant to the last sentence of Section 8.6(a), the Borrower may, within 15 days of its receipt of a request that it consent to such assignment, nominate by notice to the Agent and such Bank a bank which, if it is not a Bank, is acceptable to the Agent, and which unconditionally offers in writing (with a copy to the Agent) to purchase and assume, to the extent of the amount of such proposed assignment, in accordance with all of the provisions of the last sentence of Section 8.6(a) (including execution of an appropriate Transfer Agreement), all of such Bank's rights and obligations (including, without limitation, its Commitment) hereunder and interest in the Advances owing to such Bank and the Notes held by such Bank without recourse at par plus interest accrued thereon to the date of such purchase on a date therein specified (not less than three nor greater than five Business Days after such nomination). Such Bank at its option may elect to accept or not accept such purchase offer. If a Bank accepts such an offer and the bank first nominated by the Borrower pursuant to this Section 8.6(b) fails to purchase such rights and interest on such specified date in accordance with the terms of such offer, the Borrower may, within 15 days of such failure, repeat the process contemplated by the first sentence of this Section 8.6(b) by nominating another bank for purposes of this Section 8.6(b) by notice to the Agent and such Bank. If (i) the Borrower does not so nominate such a bank, within 15 days of its receipt of such request that it consent to such assignment, or (ii) the Borrower fails to nominate another bank following such a failure to purchase or (iii) such second nominated bank fails to purchase in accordance with the terms of an offer complying with the first sentence of this Section 8.6(b), the Borrower shall be deemed to have relinquished its right to consent to such assignment. If such Bank elects to not accept such a purchase offer under this Section 8.6(b) as to a particular proposed assignment, the Borrower shall not be deemed to have relinquished its right to consent to such assignment.

47

(c) The Borrower agrees to promptly execute the Transfer Agreement pertaining to any assignment as to which approval by the Borrower of the assignee is not required by clause (I) of the last paragraph of Section 8.6(a).

(d) Any Bank may assign, as collateral or otherwise, any of its rights (including, without limitation, rights to payments of principal of and/or interest on the Notes) under this Agreement or any of the Notes to any Federal Reserve Bank without notice to or consent of the Borrower or the Agent.

Section 8.7 Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

Section 8.8 Interest. It is the intention of the parties hereto that the Agent and each Bank shall conform strictly to usury laws applicable to it, if any. Accordingly, if the transactions with the Agent or any Bank contemplated hereby would be usurious under applicable law, then, in that event, notwithstanding anything to the contrary in the Notes, this Agreement or any other agreement entered into in connection with or as security for this Agreement or the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received by the Agent or such Bank, as the case may be, under the Notes, this Agreement or under any other agreement entered into in connection with or as security for this Agreement or the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law and any excess shall be canceled automatically and, if theretofore paid, shall at the option of the Agent or such Bank, as the case may be, be credited by the Agent or such Bank, as the case may be, on the principal amount of the obligations owed to the Agent or such Bank, as the case may be, by the Borrower or refunded by the Agent or such Bank, as the case may be, to the Borrower, and (ii) in the event that the maturity of any Note or other obligation payable to the Agent or such Bank, as the case may be, is accelerated or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to the Agent or such Bank, as the case may be, may never include more than the maximum amount allowed by such applicable law and excess interest, if any, to the Agent or such Bank, as the case may be, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall, at the option of the Agent or such Bank, as the case may be, be credited by the Agent or such Bank, as the case may be, on the principal amount of the obligations owed to the Agent or such Bank, as the case may be, by the Borrower or refunded by the Agent or such Bank, as the case may be, to the Borrower.

Section 8.9 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Section 8.10 Survival of Agreements, Representations and Warranties, Etc. All warranties, representations and covenants made by the Borrower or any officer of the Borrower herein or in any

48

certificate or other document delivered in connection with this Agreement shall be considered to have been relied upon by the Banks and shall survive the issuance and delivery of the Notes and the making of the Advances regardless of any investigation. The indemnities and other payment obligations of the Borrower contained in this Agreement, and the indemnities by the Banks in favor of the Agent and its officers, directors, employees and agents, will survive the repayment of the Advances and the termination of this Agreement.

Section 8.11 Borrower's Right to Apply Deposits. In the event that any Bank is placed in receivership or enters a similar proceeding, the Borrower may, to the full extent permitted by law, make any payment due to such Bank hereunder, to the extent of finally collected unrestricted deposits of the Borrower in U.S. dollars held by such Bank, by giving notice to the Agent and such Bank directing such Bank to apply such deposits to such indebtedness. If the amount of such deposits is insufficient to pay such indebtedness then due and owing in full, the Borrower shall pay the balance of such insufficiency in accordance with this Agreement.

Section 8.12 Confidentiality. Each Bank agrees that it will use best efforts, to the extent not inconsistent with practical business requirements, not to disclose without the prior consent of the Borrower (other than to employees, auditors, accountants, counsel or other professional advisors of the Agent or any Bank) any information with respect to the Borrower or its Subsidiaries which is furnished pursuant to this Agreement and which (i) the Borrower in good faith considers to be confidential and (ii) is either clearly marked confidential or is designated by the Borrower to the Agent or the Banks in writing as confidential, provided that any Bank may disclose any such information (a) as has become generally available to the public, (b) as may be required or appropriate in any report, statement or testimony submitted to or required by any municipal, state or Federal regulatory body having or claiming to have jurisdiction over such Bank or submitted to or required by the Board of Governors of the Federal Reserve System or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, (c) as may be required or appropriate in response to any summons or subpoena in connection with any litigation, (d) in order to comply with any law, order, regulation or ruling applicable to such Bank, (e) to the prospective transferee in connection with any contemplated transfer of any of the Notes or any interest therein by such Bank, provided that such prospective transferee executes an agreement with or for the benefit of the Borrower containing provisions substantially identical to those contained in this Section 8.12, and provided further that if the contemplated transfer is a grant of a participation in a Note (and not an assignment), no such information shall be authorized to be delivered to such participant pursuant to this clause (e) except (i) such information delivered pursuant to
Section 4.1(e) or Section 5.1(b) (other than paragraph (iv) thereof), and (ii) if prior notice of the delivery thereof is given to the Borrower, such information as may be required by law or regulation to be delivered, (f) in connection with the exercise of any remedy by such Bank pertaining to this Agreement, any of the Notes or any other document delivered in connection herewith, (g) in connection with any litigation involving such Bank pertaining to this Agreement, any of the Notes or any other document delivered in connection herewith, (h) to any Bank or the Agent, or (i) to any affiliate of any Bank, provided that such affiliate executes an agreement with or for the benefit of the Borrower containing provisions substantially identical to those contained in this Section 8.12.

h) Any Lien arising by reason of deposits with or the giving of any form of security to any governmental agency or any body created or approved by law or governmental regulation for any purpose at any time as required by law or governmental regulation (i) as a condition to the transaction by TWC or any of its Subsidiaries of any business or the exercise by TWC or any of its Subsidiaries of any privilege or license,
(ii) to enable TWC or any of its Subsidiaries to maintain self-insurance or to participate in any fund for liability on any insurance risks or (iii) in connection with workmen's compensation, unemployment insurance, old age pensions or other social security with respect to TWC or any of its Subsidiaries to share in the privileges or benefits required for companies participating in such arrangements.

January ___, 1999

To each of the Banks parties to the Amended and Restated Credit Agreement, dated as of January 26, 1999, by and among
Williams Holdings of Delaware, Inc.,
the Banks parties thereto and Citibank, N.A., as Agent for the Banks

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.1(d) of the Amended and Restated Credit Agreement, dated as of January 26, 1999 (the "Credit Agreement"), by and among Williams Holdings of Delaware, Inc., a Delaware corporation (the "Borrower"), the Banks parties thereto and Citibank, N.A., as Agent for the Banks. Terms defined in the Credit Agreement are used herein as therein defined.

I am General Counsel of TWC, and I have acted as counsel for the Borrower in connection with the preparation, execution and delivery of the Credit Agreement and the A Notes.

In that connection, either I or the attorneys acting under my supervision have examined:

(1) Original counterparts of the Credit Agreement executed by the Agent and the Borrower and the ___ original A Notes dated January 26, 1999 executed by the Borrower ("Executed Notes").

(2) The documents furnished by the Borrower pursuant to Section 3.1 of the Credit Agreement.

(3) The Certificate of Incorporation of the Borrower and all amendments thereto (the "Charter" of the Borrower).

(4) The by-laws of the Borrower and all amendments thereto (the "By-laws").

(5) Certificates of the Secretary of State of the State of Delaware, dated ____________, 1999, attesting to the continued corporate existence and good standing of the Borrower in that State.

I have also examined the originals, or copies certified to my satisfaction, of such corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments, and other documents, as I have deemed necessary as a basis for the


_______________________, 1999

Page 2

opinions expressed below. As to questions of fact material to such opinions, I have, when relevant facts were not independently established by me, relied upon certificates of officers of the Borrower or of public officials. I have assumed
(i) the genuineness of all signatures of the Banks and the Agent, (ii) the capacity of the signing officers of each of the Banks and the Agent, (iii) the authenticity of all documents submitted to me as original and the conformity with the authentic originals of all documents submitted to me as copies and (iv) the due execution and delivery, pursuant to due authorization, of the Credit Agreement by the Banks and the Agent and the enforceability (subject to limitations on enforceability of the types referred to in paragraphs (a) through
(c) of this opinion) of the Credit Agreement against the Banks and the Agent.

Based upon the following and upon such investigation as I have deemed necessary, I am of the following opinion:

(1) The Borrower is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware.

(2) The execution, delivery, and performance by the Borrower of the Credit Agreement, the Executed Notes executed by the Borrower, and the Notes to be executed by the Borrower and the consummation of the transactions contemplated by the Credit Agreement are within the Borrower's corporate powers, (a) have been duly authorized by all necessary corporate action, (b) do not contravene (i) the Charter or the By-laws of the Borrower,
(ii) any law, rule, or regulation applicable to the Borrower (including, without limitation, Regulation X of the Board of Governors of the Federal Reserve System) or (iii) any contractual or legal restriction and (c) will not result in or require the creation or imposition of any Lien prohibited by the Credit Agreement. With respect to the Notes to be executed after the date hereof by the Borrower, this opinion is limited to the law, the Charter and By-laws of the Borrower and restrictions in effect on the date hereof. The Credit Agreement has been duly executed and delivered by the Borrower and the Executed Notes have been duly executed and delivered by the Borrower. The Borrower has duly executed and delivered to the Agent an A Note payable to each Bank.

(3) No authorization, approval, or other action by, and no notice to or filing with, any governmental authority or regulatory body is required for the due execution, delivery, and performance by the Borrower of the Credit Agreement and the respective Notes or the consummation of the transactions contemplated by the Credit Agreement, except in the case of such performance for (A) such authorizations, approvals, actions, notices, and filings which have been made or obtained and (B) such authorizations, approvals, actions, notices, and filings that are required by the terms of the Credit Agreement (such as filings made under the Securities Exchange

Page C-2

_______________________, 1999

Page 3

Act of 1934) which would not customarily be made or obtained prior to the time when they are required.

(4) Each of the Executed Notes executed by, and the other Notes when funded and when executed and delivered by, the Borrower and the Credit Agreement constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their respective terms.

(5) Except as set forth in the Public Filings, to my knowledge there are no pending or overtly threatened actions or proceedings against the Borrower or any of its Subsidiaries before any court, governmental agency or arbitrator that purport to affect the legality, validity, binding effect, or enforceability of the Credit Agreement or any of the Notes or that could reasonably be expected to have a materially adverse effect upon the financial condition or operations of the Borrower and its Subsidiaries, taken as a whole.

(6) The Borrower is not an "investment company" or a company "controlled" by an "investment company" within the meaning off the Investment Company Act of 1940, as amended. The Borrower is not a "holding company," or a "subsidiary company" of a "holding company," or an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding company," or a "public utility" within the meaning of the Public Utility Holding Company Act of 1935, as amended.

(7) In any action or proceeding arising out of or relating to the Credit Agreement or any of the Notes in any court of the State of Oklahoma or in any Federal court sitting in the State of Oklahoma, assuming (i) proper venue, jurisdiction, and a full and proper presentation of the issue and the law to the court,
(ii) such action or proceeding is not dismissed on the basis of an inconvenient forum and (iii) that the court properly applies Oklahoma law, such court would (a) recognize and give effect to the provisions of Section 8.7 of the Credit Agreement and (b) construe the Credit Agreement and the Notes in accordance with the internal laws of the State of New York. Subject to the foregoing and without limiting the generality thereof, a court of the State of Oklahoma or a Federal court sitting in the State of Oklahoma would apply the usury law of the State of New York, and would not apply the usury law of the State of Oklahoma, to the Credit Agreement and the Notes. However, if a court were to hold that the Credit Agreement or any of the Notes are governed by, or to be construed in accordance with, the laws of the State of Oklahoma, the Credit Agreement, the Executed Notes, and the other Notes, when executed, delivered and funded, would be, under the laws of the State of Oklahoma, legal, valid and binding obligations of the Borrower signatory thereto and enforceable against the Borrower in accordance with their respective terms.

(vi) clauses that incorporate by reference a document or instrument or agreement not in existence on the date hereof to the extent that any such document, instrument, or agreement is the basis of an effort to enforce the Notes or Credit Agreement, insofar as any of the foregoing are contained in the Credit Agreement or the Notes.

(g) My opinion in paragraph 1 above as to the due qualification and good standing of the Borrower is based solely on certificates, dated as of _______________, 1999 from the Secretary of State of the State of Delaware certifying as to such matters.

This opinion is solely for the benefit of the Banks and the Agent, their respective successors, assigns, participants, and other transferees and counsel for the Persons referred to in this sentence, and may be relied upon only by such Persons and such counsel.

[The Assignee is already a Bank under the Credit Agreement with a Commitment of $___________ to the Borrower prior to the assumption contemplated hereby.] [The Assignee is hereby approved by the Agent [and the Borrower] for purposes of the assignment and assumption contemplated hereby.] As contemplated by such Section 8.6, it is hereby agreed that:

(i) the Assignor is hereby released from all of its obligations under the Credit Agreement with respect to or arising as a result of the Assigned Portions of its Commitment assigned hereby;

(ii) the Assignee hereby becomes obligated for the Assigned Portions of such Commitment and all other obligations of the Assignor (including, without limitation, obligations to the Agent under Section 7.5 of the Credit Agreement or otherwise) under the Credit Agreement with respect to or arising as a result of the Assigned Portions of such Commitments;

(iii) the Assignee is hereby assigned the right to vote or consent under the Credit Agreement and the other rights and obligations of the Assignor under the Credit Agreement, in each case to the extent of the Assigned Portions of such Commitment;

[(vi)    $__________ of the Assignor's outstanding A Advances to the
         Borrower are hereby transferred to the Assignee, which amounts
         represent [the aggregate amount of all of the Assignor's
         outstanding A Advances to the Borrower respectively,] [the
         amount of the assigned portions of the outstanding A Advances
         of the Assignor to the Borrower being hereby assigned to
         Assignee a portion of each such A Advance with the assigned
         portion of each such A Advance being equal to the amount of
         such A Advance multiplied by a fraction, the numerator of

         hereby by the Assignee and the denominator of which is the
         amount of the Assignor's Commitments (without giving effect to
         any B Reduction) immediately prior to such assumption]; [and]

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of MAPCO Inc.:

We have audited the consolidated balance sheet of MAPCO Inc. and subsidiaries as of December 31, 1997, and the related consolidated statements of income, changes in stockholders' equity, and cash flows for each of the two years in the period ended December 31, 1997 (none of which are presented herein). Our audits also included the financial statement schedules listed at Item 14(a)2 in the MAPCO Inc. 1997 Annual Report on Form 10-K (not presented herein). These financial statements and financial statement schedules are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedules 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of MAPCO Inc. and subsidiaries at December 31, 1997, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 1997, in conformity with generally accepted accounting principles. Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly in all material respects the information set forth therein.

As discussed in Note 16 to the MAPCO Inc. consolidated financial statements (Note 17 to the consolidated financial statements of Williams Holdings of Delaware, Inc.), MAPCO Inc. is a defendant in litigation relating to an LPG explosion in April 1992, that occurred near an underground salt dome storage facility located near Brenham, Texas.

Effective October 1, 1997, MAPCO Inc. changed its method of accounting for business process reengineering activities to conform to the consensus reached by the Emerging Issues Task Force in Issue No. 97-13.
