                          The Williams Companies, Inc.
                   Notes to Consolidated Financial Statements
                                   (Unaudited)


1. General
- -------------------------------------------------------------------------------

   The accompanying interim consolidated financial statements of The Williams
Companies, Inc. (Williams) do not include all notes in annual financial
statements and therefore should be read in conjunction with the consolidated
financial statements and notes thereto in Williams' Annual Report on Form 10-K.
The accompanying financial statements have not been audited by independent
auditors but include all adjustments, both normal recurring and others, which,
in the opinion of Williams' management, are necessary to present fairly its
financial position at June 30, 1999, results of operations for the three and six
months ended June 30, 1999 and 1998, and cash flows for the six months ended
June 30, 1999 and 1998.

   Segment profit of operating companies may vary by quarter. Based on current
rate structures and/or historical maintenance schedules of certain of its
pipelines, Gas Pipeline experiences lower segment profits in the second and
third quarters as compared to the first and fourth quarters.


2. Basis of presentation
- -------------------------------------------------------------------------------

   In fourth-quarter 1998, Williams adopted Statement of Financial Accounting
Standards (SFAS) No. 131, "Disclosures about Segments of an Enterprise and
Related Information." Beginning January 1, 1999, Communications' 1998 segment
results have been restated to include the results of investments in certain
Brazilian and Australian telecommunications projects, which had previously been
reported in Other segment revenues and profit (loss). These investments, along
with businesses previously reported as Network Applications and certain
cost-basis investments previously reported in Network Services, are now
collectively managed and reported as Strategic Investments.

   Effective April 1, 1998, certain marketing activities were transferred from
other Energy Services segments to Energy Marketing & Trading and combined with
its energy risk trading operations. The income statement presentation relating
to certain of 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. Activity prior to this date is reflected on a "gross" basis
in the Consolidated Statement of Income. 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 are recorded in the Consolidated Balance Sheet at fair value
consistent with Energy Marketing & Trading's accounting policy.

   Certain other income statement, balance sheet, cash flow and segment asset
amounts have been reclassified to conform to the current classifications.


3. Rate refund liability reductions
- -------------------------------------------------------------------------------

   Based on second-quarter 1999 regulatory proceedings involving rate-of-return
methodology, three of the gas pipelines made reductions to certain rate refund
liabilities and related interest accruals totaling approximately $51 million, of
which $38.2 million is included in Gas Pipeline's segment revenues and segment
profit. In addition, $2.7 million is included in Midstream Gas & Liquids segment
revenues and segment profit, as a result of its management of certain regulated
gathering facilities. The balance of $10.6 million is included as a reduction of
interest accrued.


4. Asset impairments and other accruals
- -------------------------------------------------------------------------------

   Included in second-quarter 1999 other expense-net within segment costs and
expenses and Strategic Investments' segment loss are pre-tax charges totaling
$26.7 million relating to management's second-quarter decision and commitment to
sell certain network application businesses. The $26.7 million charge consists
of a $22.8 million impairment of the assets to fair value based on the expected
net sales proceeds and $3.9 million in exit costs consisting of contractual
obligations and employee-related costs. This transaction resulted in an income
tax provision of approximately $7.9 million, which reflects the impact of
goodwill not deductible for tax purposes. Segment losses for the operations
related to these assets for the three and six months ended June 30, 1999, are
$5.0 million and $9.1 million, respectively. Segment losses for the
corresponding periods in 1998 were $4.7 million and $9.6 million, respectively.
The sale of the audio and video conferencing business was completed on July 31,
1999, with no significant change required to the charges noted above.

   Included in other expense-net within segment costs and expenses and segment
profit for Petroleum Services for the three and six months ended June 30, 1998,
is a $15.5 million loss provision, including interest, for potential refunds to
customers as a result of an order from the Federal Energy Regulatory Commission
(see Note 12 for additional information).

5. Merger-related costs
- -------------------------------------------------------------------------------

   In connection with the 1998 acquisition of MAPCO Inc., Williams recognized
approximately $68 million in merger-related costs comprised primarily of outside
professional fees and early retirement and severance costs in the first and
second quarters of 1998. Approximately $42 million of these merger-related costs
is included in other expense-net within segment costs and expenses and as a
component of Energy Services' segment profit, and $26 million, unrelated to the
segments, is included in general corporate expenses.


6. Provision for income taxes
- -------------------------------------------------------------------------------

   The provision (benefit) for income taxes includes:

</TABLE>

   A federal tax refund of $321 million received in second-quarter 1999 is
reflected as a current federal benefit with an offsetting deferred federal
provision attributable to temporary differences between the book and tax basis
of certain assets.

   The effective income tax rate for 1999 is greater than the federal statutory
rate due primarily to the effects of state income taxes and the impact of
goodwill not deductible for tax purposes related to assets impaired during the
second quarter (see Note 4).

   The effective income tax rate for 1998 is greater than the federal statutory
rate due primarily to the effects of state income taxes.


7. Extraordinary loss
- -------------------------------------------------------------------------------

   In 1998, Williams 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).


8. Change in accounting principle
- -------------------------------------------------------------------------------

   Effective January 1, 1999, Williams adopted Statement of Position (SOP) 98-5,
"Reporting on the Costs of Start-Up Activities." The SOP requires that all
start-up costs be expensed as incurred, and the expense related to the initial
application of this SOP of $5.6 million (net of a $3.6 million benefit for
income taxes) is reported as the cumulative effect of a change in accounting
principle.

   Additionally, 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 was adopted first-quarter 1999. The effect of
initially applying the consensus at January 1, 1999, is immaterial to Williams'
results of operations and financial position.

   In June 1999, the Financial Accounting Standards Board (FASB) issued
interpretation No. 43, "Real Estate Sales, an interpretation of SFAS No. 66,"
which is effective for sales of real estate with property improvements or
integral equipment entered into after June 30, 1999. Under this interpretation,
sales-type lease accounting will not be appropriate for excess dark fiber
capacity transactions entered into after June 30, 1999, and, therefore, unless
title to the fibers under the lease transfers to the lessee, these transactions
will be accounted for as operating leases. Williams has not assessed the effects
of this FASB interpretation on its future operating results.

diluted earnings per common share. Inclusion of these shares would be
antidilutive.

NOTES PAYABLE

   In April 1999, Williams' communications business entered into a $1.4 billion
temporary short-term bank-credit facility, guaranteed by Williams.
Communications expects to replace this facility with a permanent bank-credit
facility in the third quarter of 1999. At June 30, 1999, $610 million was
outstanding under the temporary credit facility.

   During 1999, Williams increased its commercial paper program to $1.4 billion,
backed by a short-term bank-credit facility. At June 30, 1999, $1.2 billion of
commercial paper was outstanding under the program. Interest rates vary with
current market conditions.

   Williams also has a $1 billion credit agreement under which Northwest
Pipeline, Transcontinental Gas Pipe Line, Texas Gas Transmission, Williams
Communications Solutions, LLC and Williams Communications Group, Inc. have
access to varying amounts of the facility, while Williams has access to all
unborrowed amounts. Interest rates vary with current market conditions.

   Subsequent to June 30, 1999, Williams issued $700 million of 7.625 percent
fixed rate notes due 2019. The proceeds from this issuance were used to pay off
$450 million of obligations under William's $1 billion credit agreement and $237
million of commercial paper. As a result, $237 million of commercial paper is
classified as a non-current obligation for financial reporting purposes at June
30, 1999. An additional $150 million in current debt obligations have been
classified as non-current based on Williams' intent and ability to refinance on
a long-term basis. At June 30, 1999, the amount available on the $1 billion
credit agreement of $550 million is sufficient to complete the refinancing of
these obligations.


12.  Contingent liabilities and commitments
- -------------------------------------------------------------------------------

Rate and regulatory matters and related litigation

   Williams' interstate pipeline subsidiaries, including Williams Pipe Line,
have various regulatory proceedings pending. As a result of rulings in certain
of these proceedings, a portion of the revenues of these subsidiaries has been
collected subject to refund. The natural gas pipeline subsidiaries have accrued
approximately $189 million for potential refund as of June 30, 1999.

   In 1997, the Federal Energy Regulatory Commission (FERC) issued orders
addressing, among other things, the authorized rates of return for three of the
Williams interstate natural gas pipeline subsidiaries. All of the orders involve
rate cases that became effective between 1993 and 1995 and, in each instance,
these cases have been superseded by more recently filed rate cases. In the three
orders, the FERC continued its practice of utilizing a methodology for
calculating rates of return that incorporates a long-term growth rate component.
However, the long-term growth rate component used by the FERC is now a
projection of U.S. gross domestic product growth rates. Generally, calculating
rates of return utilizing a methodology which includes a long-term growth rate
component results in rates of return that are lower than they would be if the
long-term growth rate component were not included in the methodology. Each of
the three pipeline subsidiaries challenged its respective FERC order in an
effort to have the FERC change its rate-of-return methodology with respect to
these and other rate cases. On January 30, 1998, the FERC convened a public
conference to consider, on an industry-wide basis, issues with respect to
pipeline rates of return. In July 1998, the FERC issued orders in two of the
three pipeline subsidiary rate cases, again modifying its rate-of-return
methodology by adopting a formula that gives less weight to the long-term growth
component. Certain parties are appealing the FERC's action, because the most
recent formula modification results in somewhat higher rates of return compared
to the rates of return calculated under the FERC's prior formula. In June and
July 1999, the FERC applied the new methodology in the third pipeline subsidiary
rate case, as well as in a fourth case involving the same pipeline subsidiary.
As a result of these orders and developments in certain other regulatory
proceedings in the second quarter, each of the three gas pipeline subsidiaries
made reductions to its accrued liability for rate refunds to reflect
application of the new rate-of-return methodology (see Note 3).

   In 1992, the FERC issued Order 636, Order 636-A and Order 636-B. These
orders, which were challenged in various respects by various parties in
proceedings ruled on by the U.S. Court of Appeals for the D.C. Circuit, required
interstate gas pipeline companies to change the manner in which they provide
services. Williams' gas pipelines subsidiaries implemented restructurings in
1993.

   The only appeal challenging Northwest Pipeline's restructuring has been
dismissed. On April 14, 1998, all appeals concerning Transcontinental Gas Pipe
Line's restructuring were denied by the D.C. Circuit. Williams Gas Pipelines
Central's restructuring appeal was remanded to the FERC. The appeal of Texas
Gas' restructuring remains pending. On February 27, 1997, the FERC issued Order
No. 636-C in response to the D.C. Circuit's partial remand of the three previous
636 orders. In that order, the FERC reaffirmed that pipelines should be exempt
from sharing gas supply realignment costs. Rehearing of Order 636-C was denied
in Order 636-D. Orders 636-C and 636-D have been appealed.

   Recently, the FERC issued a Notice of Proposed Rulemaking (NOPR) and a Notice
of Inquiry (NOI), proposing revisions to regulatory policies for interstate
natural gas transportation service. In the NOPR, the FERC proposes to eliminate
the rate cap on short-term transportation services and implement regulatory
policies that are intended to maximize competition in the short-


                                       8

Notes (continued)

term transportation market, mitigate the ability of firms to exercise residual
monopoly power and provide opportunities for greater flexibility in the
provision of pipeline services and to revise certain other rate and certificate
policies. In the NOI, the FERC seeks comments on its pricing policies in the
existing long-term market and pricing policies for new capacity. Williams filed
comments on the NOPR and NOI in the second quarter of 1999.

   As a result of the Order 636 decisions described, each of the natural gas
pipeline subsidiaries has undertaken the reformation or termination of its
respective gas supply contracts. None of the pipelines has any significant
pending supplier take-or-pay, ratable take or minimum take claims. During
second-quarter 1999, Williams Gas Pipelines Central (Central) reached an
agreement with its customers, State Commissions and FERC staff concerning
recovery of certain gas supply realignment costs which arose from supplier
take-or-pay contracts.

   Current FERC policy associated with Orders 436 and 500 requires interstate
gas pipelines to absorb some of the cost of reforming gas supply contracts
before allowing any recovery through direct bill or surcharges to transportation
as well as sales commodity rates. Under Orders 636, 636-A, 636-B, 636-C and
636-D, costs incurred to comply with these rules are permitted to be recovered
in full, although a percentage of such costs must be allocated to interruptible
transportation service.

   Pursuant to a stipulation and agreement approved by the FERC, Central has
made 17 filings to recover take-or-pay and gas supply realignment costs of
$201.3 million from its customers. An intervenor filed a protest seeking to have
the FERC review the prudence of certain of the costs covered by these filings.
On July 31, 1996, the administrative law judge issued an initial decision
rejecting the intervenor's prudency challenge. On September 30, 1997, the FERC,
by a two-to-one vote, reversed the administrative law judge's decision and
determined that three contracts were imprudently entered into in 1982. Central
filed for rehearing, and management has vigorously defended the prudency of
these contracts. An intervenor also filed a protest seeking to have the FERC
decide whether non-settlement costs are eligible for recovery under Order No.
636. In January 1997, the FERC held that none of the non-settlement costs and
only 75 percent of settlement costs could be recovered by Central if the costs
were not eligible for recovery under Order No. 636. This order was affirmed on
rehearing in April 1997. On June 16, 1998, a FERC administrative law judge
issued an initial decision finding that Central had not met all the tests
necessary to show that these costs were eligible for recovery under Order No.
636. On July 20, 1998, Central filed exceptions to the administrative law
judge's decision. On May 29, 1998, the FERC approved an Order which permitted
Central to conduct a reverse auction of the gas purchase contracts which are the
subject of the prudence challenges outlined above. No party bid less than the
fixed maximum price in the approved auction and, as a result, the contracts were
not assigned. In accordance with the FERC's Orders, on September 30, 1998,
Central filed a request for authority to conduct a second reverse auction of the
contracts. Under the approved reverse auction, Central was granted authority to
assign the contracts to bidders at or below an aggregate reserve price of $112.6
million. If no unaffiliated bidders were willing to accept assignment on those
terms, Central was authorized to assign the contracts to an affiliate or a third
party and recover $112.6 million from its customers subject to the outcome of
the prudence and eligibility cases described above. The FERC also approved an
extension of the recovery mechanism for non-settlement costs through February 1,
1999.

   On January 21, 1999, Central assigned its obligations under the largest of
the three contracts to an unaffiliated third party and paid the third party $100
million. Central also agreed to pay the third party a total of $18 million in
installments over the next five years. Central received indemnities from the
third party and a release of its obligations under the contract. No parties
submitted bids at the second reverse auction, and in accordance with the tariff
provisions for the reverse auction, Central assigned the two smaller contracts
to an affiliate effective February 1, 1999. As a result of these assignments,
Central has no remaining above-market price gas contracts. Central has filed
with the FERC to recover all costs related to the three contracts.

   Central has been negotiating with the FERC and state regulators to resolve
the amount of costs which are recoverable from its customers. As a result of
these negotiations, Central expensed $58 million of costs previously expected to
be recovered and capitalized as a regulatory asset in 1998. At June 30, 1999,
Central had a $52.8 million regulatory asset representing an estimate of costs
to be recovered in the future. On April 21, 1999, Central reached an agreement
in principle with the FERC staff, the state commissions, and its customers on
all issues related to recovery of Central's remaining take-or-pay and gas supply
realignment costs. The settlement resolves all prudence, eligibility and
absorption issues at a level consistent with Central's established accruals at
June 30, 1999, and provides that Central would be allowed to recover the costs
allocated to its customers by means of a direct bill to be paid, in some
instances, over time. On June 18, 1999, Central filed a proposed stipulation and
agreement with the FERC which documents the April 21 settlement. One interested
party objected to the settlement, which is subject to FERC approval. The chief
administrative law judge dismissed the objection and certified the settlement as
"uncontested" to the FERC on July 28, 1999.

   In September 1995, Texas Gas received FERC approval of a settlement regarding
Texas Gas' recovery of gas supply realignment costs. Through June 30, 1999,
Texas Gas has paid approximately $76 million and expects to pay no more than $80
million for gas supply realignment costs, primarily as a result of contract
terminations. Texas Gas has recovered approximately $66 million, plus interest,
in gas supply realignment costs. On June 1, 1999, Texas Gas filed with the FERC
under the

                                       9
<PAGE>   11
Notes (continued)

provisions of Order No. 528 to recover 75 percent of approximately $1.8 million
in costs it has been required to pay pursuant to indemnifications for royalties.
Texas Gas began collecting these costs subject to refund effective July 1, 1999,
pursuant to a FERC order.

   The foregoing accruals are in accordance with Williams' accounting policies
regarding the establishment of such accruals which take into consideration
estimated total exposure, as discounted and risk-weighted, as well as costs and
other risks associated with the difference between the time costs are incurred
and the time such costs are recovered from customers. The estimated portion of
such costs recoverable from customers is deferred or recorded as a regulatory
asset based on an estimate of expected recovery of the amounts allowed by the
FERC policy. While Williams believes that these accruals are adequate and the
associated regulatory assets are appropriate, costs actually incurred and
amounts actually recovered from customers will depend upon the outcome of
various court and FERC proceedings, the success of settlement negotiations and
various other factors, not all of which are presently foreseeable.

   On July 15, 1998, Williams Pipe Line (WPL) received an Order from the 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 $170
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. On May 20, 1999,
WPL submitted an uncontested offer of settlement to the presiding administrative
law judge that, if approved by the FERC, would resolve all outstanding rate
issues on WPL from September 1, 1990 to the present. This settlement was
certified to the FERC as uncontested on June 23, 1999. WPL is currently awaiting
FERC action on the settlement.

Environmental matters

   Since 1989, Texas Gas and Transcontinental Gas Pipe Line have had studies
under way to test certain of their facilities for the presence of toxic and
hazardous substances to determine to what extent, if any, remediation may be
necessary. Transcontinental Gas Pipe Line has responded to data requests
regarding such potential contamination of certain of its sites. The costs of any
such remediation will depend upon the scope of the remediation. At June 30,
1999, these subsidiaries had reserves totaling approximately $26 million for
these costs.

   Certain Williams subsidiaries, including Texas Gas and Transcontinental Gas
Pipe Line, 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 does not believe that these
obligations or the PRP status of these subsidiaries will have a material adverse
effect on its financial position, results of operations or net cash flows.

   Transcontinental Gas Pipe Line, Texas Gas and Central have identified
polychlorinated biphenyl (PCB) contamination in air compressor systems, soils
and related properties at certain compressor station sites. Transcontinental Gas
Pipe Line, Texas Gas and Central have also been involved in negotiations with
the U.S. Environmental Protection Agency (EPA) and state agencies to develop
screening, sampling and cleanup programs. In addition, negotiations with certain
environmental authorities and other programs concerning investigative and
remedial actions relative to potential mercury contamination at certain gas
metering sites have been commenced by Central, Texas Gas and Transcontinental
Gas Pipe Line. As of June 30, 1999, Central had recorded a liability for
approximately $11 million, representing the current estimate of future
environmental cleanup costs to be incurred over the next six to ten years. Texas
Gas and Transcontinental Gas Pipe Line likewise had recorded liabilities for
these costs which are included in the $26 million reserve mentioned above.
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. Texas Gas, Transcontinental Gas Pipe Line and Central have
deferred these costs as incurred pending recovery through future rates and other
means.

   Transco received a letter stating that the U.S. Department of Justice (DOJ),
at the request of the EPA, intends to file a civil action against Transco
arising from its waste management practices at Transco's compressor stations and
metering stations in eleven states from Texas to New Jersey. DOJ stated in the
letter that its complaint will seek civil penalties and injunctive relief under
federal environmental laws. DOJ has offered to discuss settlement of the claim.
While no specific amount was proposed, DOJ stated that any settlement must
include an appropriate civil penalty for the alleged violations. Transco cannot
reasonably estimate the amount of its potential liability, if any, at this time.
However, Transco believes it has substantially addressed environmental

                                       10

<PAGE>   12
Notes (continued)

concerns on its system through ongoing voluntary remediation and management
programs.

   Energy Services (WES) also accrues environmental remediation costs for its
natural gas gathering and processing facilities, petroleum products pipelines,
retail petroleum, refining and propane marketing operations primarily related to
soil and groundwater contamination. At June 30, 1999, WES and its subsidiaries
had liabilities totaling approximately $38 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 June 30, 1999, WES and its subsidiaries
had receivables totaling $15 million.

   In connection with the 1987 sale of the assets of Agrico Chemical Company,
Williams agreed to indemnify the purchaser for environmental cleanup costs
resulting from certain conditions at specified locations, to the extent such
costs exceed a specified amount. At June 30, 1999, Williams had approximately
$11 million accrued for such excess costs. The actual costs incurred will depend
on the actual amount and extent of contamination discovered, the final cleanup
standards mandated by the EPA or other governmental authorities, and other
factors.

   A lawsuit was filed in May 1993, in a state court in Colorado in which
certain claims have been made against various defendants, including Northwest
Pipeline, contending that gas exploration and development activities in portions
of the San Juan Basin have caused air, water and other contamination. The
plaintiffs in the case sought certification of a plaintiff class. In June 1994,
the lawsuit was dismissed for failure to join an indispensable party over which
the state court had no jurisdiction. The Colorado court of appeals affirmed the
dismissal and remanded the case to Colorado district court for action consistent
with the appeals court's decision. Since June 1994, eight individual lawsuits
were filed against Northwest Pipeline and others in U.S. district court in
Colorado, making essentially the same claims. The district court stayed all of
the cases involving Northwest Pipeline until the plaintiffs exhausted their
remedies before the Southern Ute Indian Tribal Court. Some plaintiffs filed
cases in the Tribal Court, but none named Northwest Pipeline as a defendant. The
parties have now executed a settlement agreement which settles all Federal and
Tribal cases.

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 ("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. As of January 1999, the only lawsuit not fully
resolved was 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. 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 decisions, provided for aggregate payments of
approximately $13.6 million, the full amount of which has been previously
accrued. The releases from the last remaining plaintiffs were received in
February 1999.

   In 1991, the Southern Ute Indian Tribe (the Tribe) filed a lawsuit against
Williams Production Company (Williams Production), 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 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. After
the Court of Appeals decision, Williams Production entered into an agreement in
principle to settle the Tribe's claims against it. Under the agreement, Williams
has agreed to pay certain costs associated with production and transfer a
portion of its
                                       11

interest to the Tribe. The Tribe would release Williams Production from the
claims asserted in the lawsuit. Williams, Amoco and the Tribe continue to
negotiate the terms of this settlement in principle. The Supreme Court granted a
writ of certiorari in respect of the Court of Appeals affirmation of the
decision en banc, and on June 7, 1999, the Supreme Court reversed the decision
of the Court of Appeals and held that the Tribe did not own the coal seam gas
produced from certain coal strata on fee lands within the exterior boundaries of
the Tribe's reservation.

   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. 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 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 a part of a mediation.

   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 Gas Pipelines
Central, Kern River Gas Transmission, Northwest Pipeline, Williams Gas Pipeline
Company, Transcontinental Gas Pipe Line Corporation, Texas Gas, 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. On April 9, 1999, the United States
Department of Justice announced that it was declining to intervene in any of the
Grynberg qui tam cases, including the action filed against the Williams entities
in the United States District Court for the District of Colorado.

   Class actions have been filed against certain communications carriers which
challenge the carriers' rights to install and operate fiber-optic systems along
railroad rights of way. Approximately 15 percent of Williams Communications
Group's ("Communications") network is installed on railroad rights of way.
Communications is a party to litigation challenging its right to use railroad
rights of way over which it has installed approximately 28 miles of its network.
The plaintiff in this action is seeking to have this matter certified as a class
action. Communications cannot quantify the impact of such claims at this time.

   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 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' future financial position, results of operations or cash flow
requirements.

Other matters

   Energy Marketing & Trading has entered into certain contracts giving Williams
the right to receive fuel conversion and certain other services for purposes of
generating electricity. At June 30, 1999, annual estimated committed payments
under these contracts range from $40 million to $214 million, resulting in total
committed payments over the next 22 years of approximately $3.2 billion.

13.  Adoption of accounting standards
- -------------------------------------------------------------------------------

   The FASB has issued SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities." This standard as amended, effective for fiscal years
beginning after June 15, 2000, 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' results of
operations and financial position is still being evaluated.

15.  Segment disclosures
- -------------------------------------------------------------------------------

   Williams evaluates performance based upon segment profit or loss from
operations which includes revenues from external and internal customers, equity
earnings, operating costs and expenses, and depreciation, depletion and
amortization. Intersegment sales are generally accounted for as if the sales
were to unaffiliated third parties, that is, at current market prices.

   Williams' 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 certain
communications-related ventures, as well as corporate operations.

   The following table reflects the reconciliation of segment profit, per the
tables on pages 14 and 15, to operating income as reported in the Consolidated
Statement of Income for the three and six months ended June 30:

   The increase in Network Services' total assets, as noted on page 15, is due
primarily to the construction of its fiber-optic network.

   The increase in Strategic Investments' total assets, also noted on page 15
and the investment balance in the Consolidated Balance Sheet, is due primarily
to the additional investments in a Brazilian telecommunications project and the
increase in the carrying value of a publicly traded marketable equity security.

16. Communications initial public offering
- -------------------------------------------------------------------------------

   On April 9, 1999, Williams' communications business filed a registration
statement for an initial public equity offering which is expected to yield
proceeds of $500 million to $750 million, representing a minority interest in
its communications business. During the first quarter of 1999, Williams
announced that SBC Communications plans to acquire up to a 10 percent interest
in Williams' communications business for an investment up to $500 million.
During second-quarter 1999, Williams announced that two additional parties,
Intel and Telefonos de Mexico, had also agreed to invest in its communications
business. Communications has entered into agreements with the three companies to
receive up to a total of $725 million, subject to certain conditions. In
addition, Communications is expected to issue high-yield public debt of $1.3
billion in 1999. All of these transactions will occur simultaneously with the
public equity offering. Proceeds are expected to be reinvested in the continued
construction of Communications' national fiber-optic network and other expansion
opportunities.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations


Results of Operations

Second Quarter 1999 vs. Second Quarter 1998

CONSOLIDATED OVERVIEW

   Williams' revenues increased $212 million, or 12 percent, due primarily to
Communications' dark fiber capacity lease revenues and new business growth,
reductions to rate refund liabilities at Gas Pipeline and increased revenues at
Energy Services from electric power services activities, convenience store
sales, natural gas liquids activities, and fleet management and mobile computer
technology operations. Partially offsetting these increases were lower crude and
refined products revenues.

   Segment costs and expenses increased $254 million, or 17 percent, due
primarily to higher costs and expenses within Communications, including $26.7
million of asset impairment charges and exit costs, and increased costs at
Energy Services from electric power services activities, convenience stores and
fleet management and mobile computer technology operations. In addition,
second-quarter 1999 includes $10.5 million of expense associated with a
Williams-wide incentive program (of which $3.1 million is included in general
corporate expense). These increases were partially offset by lower crude and
refined products costs.

   Operating income decreased $40 million, or 18 percent, due primarily to a $64
million decrease at Communications, reflecting $26.7 million of asset impairment
charges and exit costs, losses from international ventures during initial
operations, and costs associated with infrastructure growth and improvement.
Partially offsetting this decrease was a $22 million increase at Gas Pipeline,
reflecting the net effect of 1999 and 1998 reductions to rate refund
liabilities.

   Income before income taxes, extraordinary loss and change in accounting
principle decreased $37 million, or 36 percent, due primarily to the decrease in
operating income.

GAS PIPELINE

   GAS PIPELINE'S revenues increased $25.3 million, or 6 percent, due primarily
to a total of $38 million of reductions to rate refund liabilities by three of
the gas pipelines resulting from second-quarter 1999 regulatory proceedings
involving rate-of-return methodology and $8 million from expansion projects and
new services. These increases were partially offset by lower rates, primarily
from transportation rate discounting and rate design, and $11 million of
favorable adjustments in 1998 from the settlement of rate case issues.

   Segment profit increased $22.2 million, or 14 percent, due primarily to the
$27 million net effect of the regulatory and rate issues discussed above,
partially offset by $5 million higher general and administrative expenses in
1999, including expenses related to information system initiatives.

   Based on current rate structures and/or historical maintenance schedules of
certain of its pipelines, Gas Pipeline experiences lower segment profits in the
second and third quarters as compared with the first and fourth quarters.

ENERGY SERVICES

   ENERGY MARKETING & TRADING'S operating results can be significantly impacted
by energy commodity price volatility. In addition, physical trading sales
revenues are reported net of the related purchase costs while non-trading
activities are not netted. As a result, net revenues (revenues less cost of
sales) is used to analyze Energy Marketing & Trading's operating results as
shown below:

</TABLE>

   Revenues decreased $28.3 million, or 5 percent, due primarily to $95 million
lower crude and refined products revenues. Partially offsetting this decrease
were $41 million higher electric power services revenues resulting from activity
in southern California initiated in June of 1998 and $27 million higher revenues
from natural gas liquids activities, which includes $7 million associated with a
petrochemical plant acquisition made on March 31, 1999 and increased physical
trading activity.

   Cost of sales decreased $48.4 million, or 10 percent, due primarily to $83
million lower costs for crude and refined products. Partially offsetting this
decrease was $21 million of costs associated with electric power services
activities in southern California initiated in June of 1998.

   Net revenues increased $20.1 million, or 37 percent, due primarily to $20
million higher electric power services margins resulting from activity in
southern California, including the recognition of $7 million of revenues
associated with a 1998 contractual dispute which was settled in the second
quarter of 1999, and $20 million higher natural gas liquids margins. The natural
gas liquids margin increase reflects improved per-unit margins experienced on
all natural gas liquids products and $7 million associated with the
petrochemical plant acquisition. Partially offsetting these increases were $12
million lower crude and refined products margins primarily due to higher trading
origination revenues in 1998, and $6 million lower margins from energy financing
activities.

   Segment profit increased $13.2 million, from $2.3 million in 1998, due
primarily to the $20 million increase in net revenues and a $5.6 million gain on
the sale of certain retail gas and electric assets, partially offset by $11
million higher selling, general and administrative expenses. The increase in
selling, general and administrative expenses reflects higher compensation levels
associated with improved operating performance, growth in electric power
services operations, the late 1998 Volunteer Energy acquisition and increased
activities in human resources development, investor/media/customer relations and
business development.

   EXPLORATION & PRODUCTION'S revenues increased $5.5 million, or 15 percent,
due primarily to $8 million associated with increases in both company-owned
production volumes and marketing volumes from Williams Coal Seam Gas Royalty
Trust (Royalty Trust) and royalty interest owners, and $5 million from the April
1999 acquisition of oil and gas producing properties. Company-owned production
has increased due mainly to a drilling program initiated in the San Juan basin
in 1998. These increases were partially offset by a $7 million decrease in the
recognition of income previously deferred from a 1997 transaction that
transferred certain nonoperating economic benefits to a third party.

   Segment profit decreased $1 million, or 12 percent, due primarily to $7
million decreased recognition of deferred income and $3 million higher operating
and maintenance expense, partially offset by the $4 million favorable effect of
the April 1999 acquisition and $5 million higher revenue from increased
company-owned production volumes.

   MIDSTREAM GAS & LIQUIDS' revenues increased $34.8 million, or 17 percent, due
primarily to unfavorable adjustments in 1998 of $12 million related to rates
placed into effect in 1997 for Midstream's regulated gathering activities
(offset in costs and operating expenses), a $3 million favorable rate adjustment
in 1999, $13 million higher natural gas liquids sales from processing activities
and $5 million higher natural gas liquids storage revenues following the
acquisition of a Kansas storage facility during the second quarter of 1999,
partially offset by $6 million lower equity earnings including a $4 million
adjustment on the Discovery pipeline project related to a prior year (offset in
interest capitalized). The $13 million higher natural gas liquids sales reflects
$7 million from a 24 percent increase in volumes sold and $6 million from a 17
percent increase in average natural gas liquids sales prices.

   Costs and operating expenses increased $27 million due primarily to the 1998
rate adjustments related to Midstream's regulated gathering activities and $8
million of higher fuel and replacement gas purchases.

   Segment profit decreased $1.2 million, or 2 percent, due primarily to the $6
million lower equity earnings discussed above, $5 million of costs associated
with a cancelled pipeline construction project, $3 million higher general and
administrative expenses and $4 million higher operating and maintenance
expenses. Partially offsetting these decreases were $5 million higher natural
gas liquids storage revenues, $4 million higher natural gas liquids margins, $3
million higher

                                       17

<PAGE>   19

gathering revenues, the $3 million favorable rate adjustment in 1999 and the
impact of a $3 million unfavorable litigation judgement in 1998.

   PETROLEUM SERVICES' revenues increased $28 million, or 4 percent, due
primarily to $33 million higher convenience store sales, $25 million higher
revenues from growth in fleet management and mobile computer technology
operations, and $8 million in revenues from a recently acquired petrochemical
plant. Partially offsetting these increases were $19 million lower pipeline
construction revenues following substantial completion of the project, $10
million lower refining revenues and $6 million lower ethanol sales revenues
reflecting lower average ethanol sales prices. The $33 million increase in
convenience store sales reflects $21 million from 17 percent higher gasoline and
diesel sales volumes, $3 million from slightly higher average sales prices and
$9 million higher merchandise sales. The average number of convenience stores
and per-store sales in second-quarter 1999 have increased as compared to 1998.
The $10 million decrease in refining revenues reflects a 2 percent decrease in
refined product volumes sold, partially offset by 3 percent higher average sales
prices.

   Costs and operating expenses increased $49 million, or 9 percent, due
primarily to $25 million higher costs from growth in fleet management and mobile
computer technology operations, $23 million higher refining costs, $13 million
higher convenience store external cost of sales and $7 million higher
convenience store operating costs, partially offset by $18 million lower
pipeline construction costs. Increased refining costs of $23 million reflect $24
million from a 9 percent increase in average per-unit cost of sales and $3
million higher operating costs at the Alaska refinery, partially offset by $4
million associated with a 2 percent decrease in volumes sold. The $13 million
increase in convenience store external cost of sales reflects $7 million higher
merchandise costs, increased volumes sold and higher average gasoline and diesel
purchase prices.

   Segment profit decreased $14.9 million, or 33 percent, due primarily to $13
million from lower per-unit refining margins, $10 million higher selling,
general and administrative expenses and $7 million higher convenience store
operating costs, partially offset by the impact of a $15.5 million accrual in
1998 for potential refunds to transportation customers.

COMMUNICATIONS

   COMMUNICATIONS SOLUTIONS' revenues increased $11.1 million, or 3 percent, due
primarily to $14 million higher sales from new systems and upgrades and $6
million of other revenue in 1999 associated with the sale of rights to future
cash flows from equipment lease renewals, partially offset by $9 million lower
customer service orders resulting, in part, from competitive pressures.

   Segment profit decreased $19 million, from an $11 million segment profit in
1998 to an $8 million segment loss in 1999, due primarily to $21 million higher
selling, general and administrative expenses. Selling, general and
administrative expenses increased primarily as a result of costs necessary to
improve managing and integrating complex business operations and systems
including $6 million of higher information and technology costs, $3 million of
process related consulting fees, $2 million higher depreciation expense and $2
million of severance costs. Also contributing to the selling, general and
administrative expense increase are a $2 million increase in the provision for
uncollectible trade receivables and $3 million of expense associated with a
Williams-wide incentive program.

   NETWORK SERVICES' revenues increased $58.1 million from $30.8 million in
1998, due primarily to $20 million of revenue in 1999 from dark fiber capacity
leases accounted for as sales-type leases on the newly constructed digital
fiber-optic network and $34 million from business growth from data and switched
voice services.

   Costs and operating expenses increased $57 million, from $27 million in 1998,
due primarily to $30 million of increased costs from providing data and switched
voice services which includes $18 million of higher leased capacity costs
associated with providing customer services prior to completion of the new
network. Also contributing to the increase are $12 million higher operations and
maintenance expenses on the newly completed portions of the network, $7 million
of construction costs associated with the dark fiber capacity leases and $4
million higher depreciation expense.

   Segment loss increased $13.8 million, from a $6.5 million loss in 1998 to a
$20.3 million loss in 1999, due primarily to a $15 million increase in selling,
general and administrative expenses primarily associated with expanding the
infrastructure in support of the network expansion, losses experienced from
providing customer services prior to completion of the new network and $4
million higher depreciation expense, partially offset by $13 million of profit
from the dark fiber capacity leases.

   STRATEGIC INVESTMENTS' revenues increased $10.3 million, or 21 percent, due
primarily to $8 million of revenue contributed by an Australian
telecommunications company acquired in August 1998 and $6 million associated
with business growth, partially offset by equity investment losses of $5 million
from ATL-Algar Telecom Leste S.A. (ATL), a Brazilian telecommunications business
in initial operations.

                                       18

<PAGE>   20
   Costs and operating expenses increased $9 million, or 18 percent, and
selling, general and administrative expenses increased $7 million, or 38
percent, due primarily to the Australian operations.

   Segment loss increased $31.5 million, from a $16.3 million loss in 1998 to a
$47.8 million loss in 1999, due primarily to $26.7 million of asset impairment
charges and exit costs in 1999 (included in other expense - net within segment
costs and expenses) relating to management's second-quarter 1999 decision and
commitment to sell the audio and video conferencing and closed-circuit video
broadcasting businesses (see Note 4 of Notes to Consolidated Financial
Statements) and $10 million of losses from the start-up activities of the
Australian and Brazilian communications operations.

CONSOLIDATED

   INTEREST ACCRUED increased $8.1 million, or 6 percent, due primarily to
higher borrowing levels including the commercial paper program, Williams
Communications Group's (Communications) short-term credit facility and the July
1998 issuance of additional public debt, partially offset by a $10.6 million
favorable adjustment related to the reduction of certain rate refund liabilities
(see Note 3) and lower average interest rates. Interest capitalized increased
$9.7 million, from $7.8 million in 1998, due primarily to adjustments totaling
$7 million related to Williams' equity investments in pipelines under
construction. Investing income decreased $4.1 million, or 42 percent, due
primarily to lower interest income on long-term notes receivable. Other income
(expense) - net is $5.5 million favorable as compared to 1998 due primarily to a
1998 litigation loss accrual related to assets previously sold.

   The $6.5 million, or 15 percent, increase in the provision for income taxes
is primarily a result of a higher effective income tax rate, partially offset by
lower pre-tax income. The effective income tax rate in 1999 is significantly
higher than the federal statutory rate due primarily to the impact of goodwill
not deductible for tax purposes related to assets impaired during the second
quarter of 1999 (see Note 4) and the effects of state income taxes. The
effective income tax rate in 1998 exceeds the federal statutory rate due
primarily to the effects of state income taxes.

Six Months Ended June 30, 1999 vs. Six Months Ended June 30, 1998

CONSOLIDATED OVERVIEW

   Williams' revenues increased $237 million, or 6 percent, due primarily to
Communications' dark fiber capacity lease revenues and new business growth,
increased revenues from retail natural gas and electric activities following a
late 1998 acquisition, higher electric power services revenues, increased
convenience store sales and reductions to rate refund liabilities at Gas
Pipeline. Partially offsetting these increases were the effects in 1999 of
reporting certain crude and refined products revenues and natural gas liquids
revenues net of costs within Energy Services (see Note 2).

   Segment costs and expenses increased $308 million, or 10 percent, due
primarily to higher costs and expenses within Communications, including $26.7
million of asset impairment charges and exit costs, and increased costs at
Energy Services from retail gas and electric activities following a late 1998
acquisition, electric power services and convenience stores. In addition,
second-quarter 1999 includes $10.5 million of expense associated with a
Williams-wide incentive program (of which $3.1 million is included in general
corporate expense). Partially offsetting these increases were the effects in
1999 of reporting certain crude and refined products costs and natural gas
liquids costs net in revenues within Energy Services (see Note 2), and the
effect in 1998 of MAPCO merger-related costs totaling $68 million (including $26
million within general corporate expenses).

   Operating income decreased $45 million, or 10 percent, due primarily to a $94
million decrease at Communications, reflecting $26.7 million of asset impairment
charges and exit costs, losses from international ventures during initial
operations, and costs associated with infrastructure growth and improvement, and
a $21 million decrease from International activities (included in the Other
segment operating loss), reflecting losses from start-up operations. Partially
offsetting these decreases was the effect in 1998 of MAPCO merger-related costs
totaling $68 million.

   Income before income taxes, extraordinary loss and change in accounting
principle decreased $60 million, or 27 percent, due primarily to lower operating
income and $23 million higher net interest expense reflecting continued
expansion and new projects.

GAS PIPELINE

   GAS PIPELINE'S revenues increased $50 million, or 6 percent, due primarily to
a total of $41 million of reductions to rate refund liabilities by three of the
gas pipelines resulting primarily from second-quarter 1999 regulatory
proceedings involving rate-of-return methodology. Revenues also increased by $27
million related to the settlement of historical gas exchange imbalances, which
are offset in costs and operating expenses, and $15 million from expansion
projects and new services. These increases were partially offset by lower
transportation rates, primarily from transportation rate discounting and rate
design, and $11 million of favorable adjustments in 1998 from the settlement of
rate case issues.

   Segment profit increased $14 million, or 4 percent, due primarily to the $30
million net effect of the regulatory and rate issues discussed above and $9
million in lower transportation expenses. These increases were partially offset
by $9 million higher general and administrative expenses,

                                       19
<PAGE>   21


$8 million in higher depreciation and amortization expense and a $3.4 million
gain in 1998 from the sale-in-place of natural gas from a decommissioned storage
field. General and administrative expenses increased primarily from information
system initiatives and a $2.3 million accrual for damages associated with two
pipeline ruptures in the northwest.

   Based on current rate structures and/or historical maintenance schedules of
certain of its pipelines, Gas Pipeline experiences lower segment profits in the
second and third quarters as compared with the first and fourth quarters.

ENERGY SERVICES

   ENERGY MARKETING & TRADING'S operating results can be significantly impacted
by energy commodity price volatility. In addition, physical trading sales
revenues are reported net of the related purchase costs while non-trading
activities are not netted. As a result, net revenues (revenues less cost of
sales) is used to analyze Energy Marketing & Trading's operating results as
shown below:

</TABLE>

   Revenues decreased $35.8 million, or 4 percent, due primarily to $144 million
lower crude and refined products revenues and $106 million lower natural gas
liquids trading revenues resulting primarily from the impact in the first
quarter of 1999 of reporting revenues on a net basis for certain operations
previously reported on a "gross" basis (see Note 2). Partially offsetting these
decreases were $113 million higher retail gas and electric revenues following
the late 1998 acquisition of Volunteer Energy and $94 million higher electric
power services revenues resulting from activity in southern California initiated
in June 1998.

   Cost of sales decreased $95.9 million, or 11 percent, due primarily to $145
million lower costs for crude and refined products and $123 million lower
natural gas liquids trading costs resulting primarily from the impact in the
first quarter of 1999 of reporting revenues on a net basis for certain
operations previously reported on a "gross" basis (see Note 2). Partially
offsetting these decreases were $107 million higher costs for retail gas and
electric operations following the late 1998 acquisition of Volunteer Energy and
$61 million higher costs associated with electric power services activity in
southern California initiated in June of 1998.

   Net revenues increased $60.1 million, or 48 percent, due primarily to $33
million higher electric power services margins resulting from activity in
southern California, including the recognition of $7 million of revenues
associated with a 1998 contractual dispute which was settled in the second
quarter of 1999. Net revenues also increased due to $17 million higher natural
gas liquids margins, $7 million higher retail propane margins reflecting an 8
percent increase in volumes sold, and $6 million higher margins from retail gas
and electric activities. The natural gas liquids margin increase reflects
improved per-unit margins experienced on all natural gas liquids products and $7
million associated with the acquisition of a petrochemical plant in early 1999.
The improved margins from retail gas and electric activities reflects, in
part, the effect of general and administrative expenses included in equity
losses in 1998 from partially owned companies that are now consolidated.

   Segment profit increased $38.4 million, from $17.8 million in 1998, due
primarily to the $60 million increase in net revenues and a $5.6 million gain on
the sale of certain retail gas and electric assets, partially offset by $27
million higher selling, general and administrative expenses. The increase in
selling, general and administrative expenses reflects higher compensation levels
associated with improved operating performance, growth in electric power
services operations, the Volunteer Energy acquisition and increased activities
in human resources development, investor/media/customer relations and business
development.

   EXPLORATION & PRODUCTION'S revenues decreased $7.6 million, or 10 percent,
due primarily to an $11 million decrease in the recognition of income previously
deferred from a 1997 transaction that transferred certain nonoperating economic
benefits to a third party and an $11 million reduction associated with lower
average natural gas sales prices mainly during the first quarter of 1999. These
decreases were partially offset by a $10 million increase associated with
increases in both company-owned production volumes and marketing volumes from
the Royalty Trust and royalty interest owners, and $5 million from the April
1999 acquisition of oil and gas producing properties. Company-owned production
has increased due mainly to a drilling program initiated in the San Juan basin
in 1998.

   Segment profit decreased $8.6 million, or 42 percent, due primarily to $11
million decreased recognition of deferred income, a $7 million unfavorable
effect of lower average natural gas sales prices for company-owned production
and $5 million higher operating and maintenance expenses. Partially offsetting
these decreases were $7 million higher

                                       20

<PAGE>   22

revenue from increased company-owned production volumes, the $4 million
favorable effect of the April 1999 acquisition and $3 million higher margins on
natural gas marketing activities.

   MIDSTREAM GAS & LIQUIDS' revenues increased $13.1 million, or 3 percent, due
primarily to unfavorable adjustments in 1998 of $12 million related to rates
placed into effect in 1997 for Midstream's regulated gathering activities
(offset in costs and operating expenses), a $3 million favorable rate adjustment
in 1999, $5 million higher natural gas liquids sales from processing activities,
and $5 million higher natural gas liquids storage revenues following the
acquisition of a Kansas storage facility during the second quarter of 1999.
Partially offsetting these increases were $10 million lower equity earnings
including a $4 million adjustment on the Discovery pipeline project related to a
prior year (offset in capitalized interest), and $7 million lower condensate
revenues related to a shift in the revenue mix from sales of condensate for
customers to providing gathering and transportation services under fee-based
contracts. The $5 million higher natural gas liquids sales reflects $13 million
from a 19 percent increase in volumes sold, partially offset by $8 million from
a 10 percent decrease in average natural gas liquids prices.

   Costs and operating expenses increased $21 million due primarily to the 1998
rate adjustments related to Midstream's regulated gathering activities and $3
million of higher fuel and replacement gas purchases.

   Segment profit decreased $20.9 million, or 17 percent, due primarily to the
$10 million lower equity earnings discussed above, $7 million higher general and
administrative expenses, $5 of costs associated with a cancelled pipeline
construction project and $8 million higher operating and maintenance expenses.
Partially offsetting these segment profit decreases were $5 million higher
natural gas storage revenues, the $3 million favorable rate adjustment in 1999
and the impact of a $3 million unfavorable litigation judgement in 1998.

   Midstream is in the process of evaluating its organization in a portion of
the Gulf Coast operations area. As a part of this organizational assessment,
Williams will be offering certain employees enhanced retirement benefits under
an early retirement incentive program in August 1999. Preliminary estimates
indicate that this program may result in a pre-tax charge to third-quarter 1999
operating results of approximately $2 million.

   PETROLEUM SERVICES' revenues increased $19.2 million, or 2 percent, due
primarily to $50 million higher convenience store sales, $37 million higher
revenues from growth in fleet management and mobile computer technology
operations and $8 million in revenues from a recently acquired petrochemical
plant. Partially offsetting these increases were $48 million lower refining
revenues, $17 million lower pipeline construction revenues following substantial
completion of the project and $14 million lower ethanol sales reflecting lower
average ethanol sales prices. The $50 million increase in convenience store
sales reflects $46 million from 20 percent higher gasoline and diesel sales
volumes and $19 million higher merchandise sales, partially offset by $15
million from lower average retail gasoline and diesel sales prices in the first
quarter of 1999. The average number of convenience stores and per-store sales in
1999 have increased as compared to 1998. The $48 million decrease in refining
revenues reflects an 8 percent decrease in average sales prices, partially
offset by a 3 percent increase in refined product volumes sold.

   Costs and operating expenses increased $40 million, or 4 percent, due
primarily to $36 million higher costs from growth in fleet management and mobile
computer technology operations, $29 million higher convenience store external
cost of sales and $15 million higher convenience store operating costs.
Partially offsetting these increases were $16 million lower refining costs, $16
million lower pipeline construction costs and $10 million lower ethanol
production costs. The $29 million increase in convenience store external cost of
sales reflects $13 million higher merchandise costs and a 20 percent increase in
gasoline and diesel sales volumes, partially offset by a 6 percent decrease in
average gasoline and diesel purchase prices. Decreased refining costs of $16
million reflects $39 million from lower average per-unit cost of sales,
partially offset by $15 million related to increased volumes sold and $8 million
higher operating costs at the refineries.

   Selling, general and administrative expenses increased $16 million due, in
part, to increased activities in human resources development,
investor/media/customer relations and business development.

   Segment profit decreased $15.5 million, or 20 percent, due primarily to $16
million higher selling, general and administrative expenses, $15 million higher
convenience store operating costs, $14 million from lower per-unit refinery
margins and $8 million higher refinery operating costs. These decreases to
segment profit were partially offset by the impact of a $15.5 million accrual in
1998 for potential refunds to transportation customers, $6 million higher
margins on convenience store merchandise sales, $5 million of margins from the
recently acquired petrochemical plant, $4 million higher margins from growth in
the terminalling and distribution operations and the recovery of $4 million of
environmental expenses previously incurred.

   The new products pipeline, which was expected to be in service in 1998, has
been delayed until early 2000 due to environmental assessment and related
mitigation.

COMMUNICATIONS

   COMMUNICATIONS SOLUTIONS' revenues increased $21 million, or 3 percent, due
primarily to $28 million higher new system sales and upgrades and $6 million of
other revenue in 1999 associated with the sale of rights to future cash flows
from equipment lease renewals, partially offset by $17 million lower customer
service orders resulting, in part, from competitive pressures.

   Segment profit decreased $31.1 million, from a $14.3 million segment profit
in 1998 to a $16.8 million segment loss in 1999, due primarily to $37 million
higher selling, general and administrative expenses, partially offset by $4
million realized on the sale of rights to future cash flows from equipment lease
renewals. Selling, general and administrative expenses increased due primarily
to costs necessary to improve managing and integrating complex business
operations and systems including $11 million of higher information technology
costs, $4 million of process related consulting fees, $3 million higher
depreciation expense and $2 million of severance costs. Also contributing to the
selling, general and administrative expense increase are a $10 million increase
in the provision for uncollectible trade receivables and $3 million of expense
associated with a Williams-wide incentive program.

   NETWORK SERVICES' revenues increased $145.4 million from $52 million in 1998,
due primarily to $72 million of revenue in 1999 from dark fiber capacity leases
accounted for as sales-type leases on the newly constructed digital fiber-optic
network and $66 million from business growth from data and switched voice
services.

   Costs and operating expenses increased $146 million, from $45 million in
1998, due primarily to $66 million of increased costs from providing data and
switched voice services which includes $47 million of higher leased capacity
costs associated with providing customer services prior to completion of the new
network. Also contributing to the increase are $48 million of construction costs
associated with the dark fiber capacity leases, $17 million higher operations
and maintenance expenses on the newly completed portions of the network and $7
million higher depreciation expense.

   Segment loss increased $23.1 million, from a loss of $14.4 million in 1998 to
a loss of $37.5 million in 1999, due primarily to a $22 million increase in
selling, general and administrative expenses primarily associated with expanding
the infrastructure in support of the network expansion, losses experienced from
providing customer services prior to completion of the new network and $7
million higher depreciation expense, partially offset by $24 million of profit
from the dark fiber capacity leases.

   As each phase of the on-going construction of the planned 32,000 mile
full-services 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, of
which 17,000 were lit. At June 30, 1999, the network had increased to 21,000
cable miles, of which 19,000 are lit. The remaining 11,000 miles are planned to
come online during the remainder of 1999 and 2000. As a result of the expansion
of the network and as a result of alliances with SBC Communications, Intel
Corporation and Telefonos de Mexico, a significant increase in revenues as well
as a significant change in the revenue mix is expected over the next few years.

   In June 1999, the Financial Accounting Standards Board (FASB) issued
interpretation No. 43, "Real Estate Sales, an interpretation of SFAS No. 66,"
which is effective for sales of real estate with property improvements or
integral equipment entered into after June 30, 1999. Under this interpretation,
sales-type lease accounting will not be appropriate for excess dark fiber
capacity transactions entered into after June 30, 1999, and, therefore, unless
title to the fibers under the lease transfers to the lessee, these transactions
will be accounted for as operating leases.  Williams has not assessed the
effects of this FASB interpretation on its future operating results.

   STRATEGIC INVESTMENTS' revenues increased $20.7 million, or 21 percent, due
primarily to $19 million of revenue contributed by an Australian
telecommunications company acquired in August 1998 and $14 million associated
with business growth, partially offset by equity investment losses of $13
million from ATL, a Brazilian telecommunications business in initial operations.

   Costs and operating expenses increased $19 million, or 20 percent, and
selling, general and administrative expenses increased $15 million, or 39
percent, due primarily to the Australian operations.

   Segment loss increased $40 million, from a $33.3 million loss in 1998 to a
$73.3 million loss in 1999, due primarily to $26.7 million of asset impairment
charges and exit costs in 1999 (included in other expense - net within segment
costs and expenses) relating to management's second-quarter 1999 decision and
commitment to sell the audio and video conferencing and closed-circuit video
broadcasting businesses (see Note 4) and $23 million of losses from the start-up
activities of the Australian and Brazilian communications operations, partially
offset by improved results and business growth in other areas.

OTHER

   OTHER segment loss of $22 million in 1999 compares to a segment loss of $3
million in 1998, due primarily to $21 million higher international equity

communications company in which Williams has an equity interest. The equity
losses result primarily from start-up operations of certain communications
ventures within this investment.

CONSOLIDATED

   GENERAL CORPORATE EXPENSES decreased $25.4 million, or 43 percent, due
primarily to MAPCO merger-related costs of $26 million included in 1998 general
corporate expenses. An additional $42 million of merger-related costs are
included in 1998 as a component of Energy Services' segment profit (see Note 5).
Interest accrued increased $33.4 million, or 14 percent, due primarily to higher
borrowing levels including the commercial paper program, Communications'
short-term credit facility and the July 1998 issuance of additional public debt,
partially offset by a $10.6 million favorable adjustment related to the
reduction of certain rate refund liabilities (see Note 3) and lower average
interest rates. Interest capitalized increased $10.9 million, or 68 percent, due
primarily to adjustments totaling $7 million related to Williams' equity
investments in pipelines under construction. Other income (expense) - net is
$7.4 million favorable as compared to 1998 due primarily to a 1998 litigation
loss accrual related to assets previously sold.

   The $.9 million, or 1 percent, increase in the provision for income taxes is
primarily a result of a higher effective income tax rate, substantially offset
by lower pre-tax income. The effective income tax rate in 1999 is significantly
higher than the federal statutory rate due primarily to the impact of goodwill
not deductible for tax purposes related to assets impaired during the second
quarter of 1999 (see Note 4) and the effects of state income taxes. The
effective income tax rate in 1998 exceeds the federal statutory rate due
primarily to the effects of state income taxes.

   The $4.8 million 1998 extraordinary loss results from the early
extinguishment of debt (see Note 7).

   The $5.6 million 1999 change in accounting principle relates to the adoption
of Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities"
(see Note 8).

FINANCIAL CONDITION AND LIQUIDITY

Liquidity

   Williams 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 the
commercial paper program, which can be utilized without limitation under
existing loan covenants. At June 30, 1999, Williams had access to $790 million
of liquidity including $550 million available under its $1 billion bank-credit
facility, $216 million of commercial paper availability, and cash-equivalent
investments. This compares with liquidity of $738 million at December 31, 1998,
and $530 million at June 30, 1998.

   Registration statements have been filed with the Securities and Exchange
Commission by Williams and Northwest Pipeline, Texas Gas Transmission and
Transcontinental Gas Pipe Line (each a wholly owned subsidiary of Williams).
Following a July 1999 issuance of $700 million of notes, approximately $755
million of shelf availability remains under these outstanding registration
statements and may be used to issue a variety of debt or equity securities.
Williams believes any additional financing arrangements can be obtained on
reasonable terms if required.

   On April 9, 1999, Williams' communications business filed a registration
statement for an initial public equity offering which is expected to yield
proceeds of $500 million to $750 million, representing a minority interest in
its communications business. During first-quarter 1999, Williams announced that
SBC Communications plans to acquire up to a 10 percent interest in its
communications business for an investment up to $500 million. During
second-quarter 1999, Williams announced that two additional parties, Intel and
Telefonos de Mexico, have also agreed to invest in its communications business.
Communications has entered into agreements with the three companies to receive
up to a total of $725 million, subject to certain conditions. In addition,
Communications is expected to issue high-yield public debt of $1.3 billion in
1999. All of these transactions are expected to occur simultaneously with the
public equity offering. Proceeds are expected to be reinvested in the continued
construction of Communications' national fiber-optic network and other expansion
opportunities. Williams' management has announced that it expects the initial
public equity offering to close in October 1999. In April 1999, Communications
entered into a $1.4 billion interim short-term bank-credit facility expected to
be replaced with a permanent bank-credit facility in September 1999. At June 30,
1999, $790 million remains available under this facility.

   During 1998, Williams entered into an operating lease agreement covering a
portion of its fiber-optic network designed to fund up to $750 million of
capital expenditures for the fiber-optic network. As of June 30, 1999, $449
million of costs have been incurred and the remaining capacity under the program
is $301 million.

   In 1999, capital expenditures and investments are estimated to be
approximately $5 billion. During 1999, Williams expects to finance capital
expenditures, investments and working-capital requirements through (1) cash
generated from operations, (2) Communications' initial equity and high-yield
debt offerings, (3) the use of the available portion of its $1 billion
bank-credit facility, Communications' $1.4 billion short-term bank-credit
facility and the asset lease program, (4) commercial

                                       23

paper, (5) short-term uncommitted bank lines, (6) private borrowings and (7)
debt or equity public offerings.

Financing Activities

   In January 1999, the commercial paper program increased to $1.4 billion from
$1 billion. The commercial paper program is backed by short-term bank-credit
facilities totaling $1.4 billion. At June 30, 1999, $1.2 billion of commercial
paper was outstanding under the program. In January 1999, Williams entered into
a $200 million adjustable rate term loan due 2004, and in July 1999, Williams
issued $700 million of 7.625 percent notes due 2019. During second-quarter
1999, $610 million of borrowings were made under the Communications' $1.4
billion interim short-term bank-credit facility. The proceeds were used for
general corporate purposes, including the repayment of outstanding debt.

   The consolidated long-term debt to debt-plus-equity ratio was 58.9 percent at
June 30, 1999, compared to 59.9 percent at December 31, 1998. If short-term
notes payable and long-term debt due within one year are included in the
calculations, these ratios would be 66.5 percent at June 30, 1999, and 64.7
percent at December 31, 1998.

Investing Activities

   During first-quarter 1999, Williams exercised an option to increase its
investment in ATL, a Brazilian telecommunications business, by an additional 35
percent equity interest for $265 million. This investment was funded through
borrowings under the $1 billion bank-credit facility. Also in first-quarter
1999, Williams purchased a company with a petrochemical plant and natural gas
liquids transportation, storage and other facilities for $163 million in cash.

Operating Activities

   The increase in receivables and accounts payable reflects increased power and
crude oil trading activity at Energy Marketing & Trading. The change in accounts
payable also reflects an $84 million payment pursuant to a wireless fiber
capacity agreement. The decrease in accrued liabilities is due primarily to the
payment in 1999 of $100 million in connection with the assignment of Williams'
obligations under a gas purchase contract to an unaffiliated third party (see
Note 12). The decrease in accrued rate refund liabilities reflects the payment
in 1999 of $113 million of rate refunds to natural gas transportation customers
and the second-quarter 1999 reductions to rate refund liabilities (see Note 3).
In addition, during 1999 Williams has received federal income tax refunds
totaling $380 million (see Note 6).


Other
- -----
Other Commitments

   Energy Marketing & Trading entered into certain contracts during 1998 and
1999 giving Williams the right to receive fuel conversion and certain other
services for purposes of generating electricity. At June 30, 1999, annual
estimated committed payments under these contracts range from $40 million to
$214 million, resulting in total committed payments over the next 22 years of
approximately $3.2 billion.

Environmental

   Transcontinental Gas Pipe Line (Transco) received a letter stating that the
U.S. Department of Justice (DOJ), at the request of the U.S. Environmental
Protection Agency, intends to file a civil action against Transco arising from
its waste management practices at Transco's compressor stations and metering
stations in eleven states from Texas to New Jersey. DOJ stated in the letter
that its complaint will seek civil penalties and injunctive relief under federal
environmental laws. DOJ has offered to discuss settlement of the claim. While no
specific amount was proposed, DOJ stated that any settlement must include an
appropriate civil penalty for the alleged violations. Transco cannot reasonably
estimate the amount of its potential liability, if any, at this time. However,
Transco believes it has substantially addressed environmental concerns on its
system through ongoing voluntary remediation and management programs.

Year 2000 Compliance

   Williams 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

                                       24

<PAGE>   26

designated as critical and are the major focus of this project. Some
non-critical systems may not be compliant by January 1, 2000.

   Renovation/replacement and testing/validation of critical systems has been
substantially completed, except for replacement of certain critical systems
scheduled for completion later in 1999. Testing and validation activities will
continue throughout the process as replacement systems come online and as
remediation of systems pursuant to an implemented contingency plan are
completed. The following table indicates the project status as of June 30, 1999,
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.

   Williams 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 has sent approximately
17,800 letters and questionnaires to third parties including customers, vendors
and service providers. Williams is evaluating responses as they are received or
otherwise investigating the status of these companies' year 2000 compliance
efforts. As of June 30, 1999, approximately 43 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 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.

   Williams is utilizing both internal resources and external contractors to
complete the year 2000 compliance project. Williams has a core group of 236
people involved in this enterprise-wide project. This includes 17 individuals
responsible for coordinating, organizing, managing, communicating, and
monitoring the project and another 219 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 an additional 500 to 1,200
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. Gas Pipeline has contracted with an external
contractor for a cost of up to $6 million for the remediation of the customer
service software. Within Energy Services, two external contractors are being
utilized at a total cost of approximately $2 million.

   Several previously planned system implementations have been or are scheduled
for completion during 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
are coming online in stages during 1999 and 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 in early 1998. Those applications have been
incorporated into the enterprise-wide project and remaining system replacements
are proceeding on schedule. In addition, the Petroleum Services business unit of
Energy Services is replacing its current ATLAS and revenue billing systems. The
new ATLAS system will be used to manage refined product pipeline transportation,
manage customer product inventories, authorize supplier and customer terminal
loading and track loading balances. The new revenue billing system will
interface with ATLAS to appropriately bill customers and account for the
transactions. Current plans are to implement these new systems before November
1, 1999. The Midstream Gas & Liquids business unit of Energy Services plans to
implement a new Gas Management and Gathering & Processing Accounting System
(GasKit). GasKit, which is targeted to be online for November 1999 business,
will integrate management of gas nominations and volume allocations with revenue
billing. Gas Pipeline completed implementation of a new telephone system in
1998, and a new common financial system was implemented July 1, 1999 at one of
the pipelines.

   Although all critical systems over which Williams has control are planned to
be compliant and tested before the year 2000, Williams has identified two areas
that would equate to a most reasonably

                                       25

<PAGE>   27

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 with and evaluation of third-party compliance plans and by
the development of contingency 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. In situations where planned system implementations
will not be in service timely or are delayed past an implementation date of
September 1, 1999, alternative steps are being taken to make existing systems
compliant. It is not possible to quantify the possible financial impact if this
most reasonably likely worst case scenario were to come to fruition.

   Significant focus on the contingency plan phase of the project has been
taking place in 1999. Guidelines for the contingency planning process were
issued in January 1999. 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. The following is
a discussion of contingency plans that have been developed to date. Gas
Pipeline's contingency plans include manning all operational stations
twenty-four hours a day, putting extra security measures into place and stocking
up on supplies. In addition, most of Gas Pipeline's compressor stations are
capable of independently generating electricity in the event of a loss of
electricity, and operation of the pipelines can be done manually in case there
is a loss of telecommunications capability. Because of the delay in the
implementation date of the new ATLAS and revenue billing systems at Petroleum
Services to October 1999, the contingency plan for those systems has been
implemented. That plan includes the modification and testing of the existing
ATLAS and revenue billing systems by the end of October 1999 to ensure that a
compliant system is in place in case the new systems' implementation date is
delayed further. Due to the delay in the implementation of the GasKit system at
Midstream Gas & Liquids from June 1999 to November 1999, the current system is
currently being assessed and is targeted to be year 2000 compliant by
November 15, 1999. Communications engaged an outside consultant to assist in
identifying potential impacts to its business areas and processes. This review
was completed in June 1999 and the information is now being used to enhance the
development of contingency plans at Communications. Contingency plans for the
corporate headquarters' data centers include onsite or on-call personnel to
monitor systems and resolve problems, backup generators in the event of loss of
electric power, and backup chiller systems/trailer mounted chillers in case of
the loss of chiller capability from the third-party supplier.

   Costs incurred for new software and hardware purchases are being capitalized
and other costs are being expensed as incurred. Williams currently estimates the
total cost of the enterprise-wide project, including any accelerated system
replacements, to be approximately $49 million. This $49 million has been or is
expected to be spent as follows:

   o  Prior to 1998 and during the first quarter of 1998, Williams was
      conducting the project awareness and inventory/assessment phases of the
      project and incurred costs totaling $3 million.

   o  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.

   o  The third and fourth quarters of 1998 focused on the
      renovation/replacement and testing/validation phases, and $10 million was
      incurred.

   o  During the first quarter of 1999, renovation/replacement and
      testing/validation continued, contingency planning began and $9 million
      was incurred.

   o  During the second quarter of 1999, the primary focus shifted to
      testing/validation and contingency planning, and $10 million was spent.

   o  The third and fourth quarters of 1999 will focus mainly on contingency
      planning and final testing with $13 million expected to be spent.

   o  Approximately $2 million is estimated to be spent during the first two
      quarters of 2000 for monitoring and problem resolution.

   Of the $34 million incurred to date, approximately $31 million has been
expensed, and approximately $3 million has been capitalized. Of the $15 million
of future costs necessary to complete the project within the schedule described,
approximately $12 million will be expensed and the remainder capitalized. This
estimate does not include Williams' 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

                                       26

<PAGE>   28

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 3.

   Quantitative and Qualitative Disclosures About Market Risk

   During the first quarter of 1999, Williams issued $200 million in adjustable
rate debt due in 2004 at an initial rate of approximately 5.3 percent.

   Subsequent to June 30, 1999, Williams issued $700 million of 7.625 percent
fixed rate notes due 2019.

   At June 30, 1999, Williams has preferred stock interests in certain
Brazilian ventures totaling $362 million. Estimating cash flows from these
investments is not practical given that the cash flows from or liquidation of
these investments are uncertain. The Brazilian economy has experienced
significant volatility in 1999 resulting in an approximate 32 percent reduction
in the Brazilian Real against the U.S. dollar. However, Williams believes the
fair value of these investments approximates the carrying value. An additional
20 percent reduction in the value of the Brazilian Real against the U.S. dollar
could result in up to a $72 million reduction in the fair value of these
investments. This analysis assumes a direct correlation in the fluctuation of
the Brazilian Real against the value of our investments. The ultimate duration
and severity of the conditions in Brazil remains uncertain, as does the
long-term impact on our interests in the ventures. Williams continues to monitor
currency fluctuations in this region and considers the employment of strategies
to hedge currency movements when cash flows from these investments warrant the
need for such consideration.
