        CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION FOR
                 THE PURPOSE OF "SAFE HARBOR" PROVISIONS OF THE
                PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This quarterly report on Form 10-Q contains forward-looking  statements relating
to Chevron's  operations  that are based on management's  current  expectations,
estimates and projections  about the petroleum and chemicals  industries.  Words
such as "expects," "intends," "plans," "projects,"  "believes,"  "estimates" and
similar expressions are used to identify such forward-looking statements.  These
statements are not guarantees of future  performance  and involve certain risks,
uncertainties and assumptions that are difficult to predict.  Therefore,  actual
outcomes and results may differ  materially from what is expressed or forecasted
in such forward-looking statements.

Among the factors that could cause actual results to differ materially are crude
oil and natural gas prices;  refining margins and marketing  margins;  chemicals
prices and competitive  conditions affecting supply and demand for the company's
aromatics,  olefins and additives  products;  potential failure to achieve,  and
potential delays in achieving,  expected production from existing and future oil
and gas  development  projects;  potential  disruption  or  interruption  of the
company's  production,   manufacturing  or  transportation   facilities  due  to
accidents or political events;  potential disruption to the company's operations
due to untimely or incomplete  resolution of Year 2000 issues by the company and
other entities with which it has material relationships; potential liability for
remedial  actions  under  existing  or  future  environmental  regulations;  and
potential  liability  resulting from pending or future litigation.  In addition,
such statements could be affected by general domestic and international economic
and political conditions.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Interim Financial Statements

The accompanying  consolidated  financial  statements of Chevron Corporation and
its subsidiaries (the company) have not been audited by independent accountants,
except  for the  balance  sheet at  December  31,  1998.  In the  opinion of the
company's  management,  the interim data include all adjustments necessary for a
fair statement of the results for the interim periods. These adjustments were of
a normal recurring nature, except for the special items described in Note 2, and
the material reclassification described in Note 3.

Certain  notes and other  information  have been  condensed  or omitted from the
interim  financial  statements  presented in this Quarterly Report on Form 10-Q.
Therefore,  these financial  statements  should be read in conjunction  with the
company's 1998 Annual Report on Form 10-K.

The results for the three- and nine-month  periods ended September 30, 1999, are
not necessarily indicative of future financial results.


Note 2. Net Income

Net income for the third  quarter 1999  included net charges of $120 million for
special  items,  compared  with net  benefits  of $75  million in the 1998 third
quarter.  The 1999  third  quarter  included  charges of $79  million  for asset
write-downs;  $31  million for the  company's  share of a loss on the sale of an
investment  by Caltex,  a 50  percent-owned  affiliate;  and $10 million for net
environmental remediation provisions.

Net  income  for the first  nine  months of 1999  included  net  charges of $206
million from special  items,  compared  with net benefits of $103 million in the
comparable 1998 period. In addition to the third quarter special charges of $120
million noted above,  the nine-month  results  included  special charges of $146
million for previously announced staff reductions and other restructuring costs,
$86 million for net environmental remediation provisions,  $43 million for asset
write-offs and $23 million for a regulatory matter.  Partially  offsetting these
charges were $152 million from gains on asset  dispositions and $60 million from
favorable prior-year tax adjustments.

Foreign  currency  losses of $7 million and $26 million  were  included in third
quarter net income in 1999 and 1998,  respectively.  For the nine-month periods,
foreign  currency  losses were $48 million in 1999,  compared  with gains of $24
million in 1998.


Note 3. Information Relating to the Statement of Cash Flows

The "Net decrease  (increase) in operating  working  capital" is composed of the

</TABLE>

In June 1999,  the company  reclassified a reserve of  approximately  $1 billion
established for the Cities Service  litigation from "Deferred  credits and other
non-current  obligations" to "Accrued  liabilities." The remaining 1999 increase
in "Accounts payable and accrued liabilities" and the 1999 increase in "Accounts
and notes  receivable"  were largely due to higher 1999 prices for crude oil and
refined   products.   The  1998  decreases  in  "Accounts  payable  and  accrued
liabilities"  and "Accounts and notes  receivable" were largely related to lower
1998 prices for crude oil and refined products.

Included in "Proceeds from issuance of long-term  debt" of $702 million are cash
proceeds of $620  million  that the company  received  from its  Employee  Stock
Ownership Plan (ESOP) in exchange for the assumption of $620 million of existing
ESOP debt in July 1999. This transaction was recorded as an increase in cash and
a reduction in "Deferred Compensation."

The  Consolidated  Statement  of Cash  Flows  excludes  the  following  non-cash
transactions:

The  Rutherford-Moran  Oil  Corporation  and  another  interest  in Block B 8/32
offshore  Thailand  were  acquired in March  1999.  The  consideration  for this
acquisition  included 1.1 million shares of the company's  treasury stock valued
at $91 million.

Concurrent with the ESOP  transaction  described  above,  the ESOP borrowed $620
million of fixed-rate debt in July 1999,  guaranteed by Chevron Corporation,  to
refinance  the debt  assumed by Chevron.  This was recorded by the company as an
increase in its debt outstanding and in "Deferred compensation."

The company's ESOP repaid $70 million and $60 million of matured debt guaranteed
by Chevron Corporation in January of 1999 and 1998, respectively. These payments
were  recorded  by the  company as a reduction  in its debt  outstanding  and in
"Deferred  compensation."  In June 1999,  the ESOP  borrowed an  additional  $25
million,  which is guaranteed by Chevron  Corporation.  This was recorded by the
company as an increase in its debt outstanding and in "Deferred compensation."

Service  litigation  from "Other  liabilities" to "Current  liabilities"  and an
increase in short-term debt. Within "Other liabilities," the reduction from this
reclassification is offset by increases in other liability accounts. The primary
cause of the  reduction  in "Net  worth"  shown above was a third  quarter  1999
return of $2 billion of capital to Chevron Corporation in exchange for a loan.


Note 6. Summarized Financial Data - Chevron Transport Corporation Limited

Effective July 1, 1999, Chevron Transport  Corporation,  a Liberian corporation,
was merged into Chevron Transport  Corporation  Limited (CTC), which assumed all
of the assets and liabilities of Chevron Transport Corporation.  CTC, a Bermuda
corporation, is an indirect, wholly owned subsidiary of Chevron Corporation. CTC
is the principal operator of Chevron's international tanker fleet and is engaged
in the marine  transportation of crude oil and refined petroleum products.  Most
of CTC's  shipping  revenue is derived by providing  transportation  services to
other Chevron  companies.  Chevron  Corporation has guaranteed this subsidiary's
obligations in connection with certain debt securities where CTC is deemed to be
an  issuer.  In  accordance  with  the  Securities  and  Exchange   Commission's
disclosure  requirements for CTC, summarized  financial  information for CTC and
its consolidated subsidiaries is presented below. This summarized financial data
was derived from the financial  statements  prepared on a  stand-alone  basis in
conformity with generally accepted accounting principles.

The increase in gross revenues for the  three-month  and  nine-month  periods is

Note 8 - Employee Termination Benefits and Other Restructuring Costs

The company  recorded net before-tax  restructuring  charges of $180 million for
the nine months ending September 30, 1999 - comprised of $197 million of charges
for  employee  termination  benefits  offset by a net credit of $17  million for
other items.

Accrual and payment activity for the employee  termination benefits is presented
in the following table:

</TABLE>


The termination  benefit charges for the nine-month  period were classified $154
million  as  "Operating  expense"  and $43  million  as  "Selling,  general  and
administrative  expense."  The staff reduction  program is being implemented in
all of the company's  operating  segments  across  several  business  functions.
Employees affected are primarily U.S.-based.  All employees must be separated by
June 30, 2000.

Termination  benefits for 2,742 of the 3,138  employees - accrued in  accordance
with SFAS No. 88,  "Employers'  Accounting for Settlements  and  Curtailments of
Defined  Benefit  Plans and for  Termination  Benefits" - are  payable  from the
funded  assets of the company's  U.S. and Canadian  pension  plans.  Payments to
other employees are from company funds.



                                      -11-
<PAGE>

Included in the net  before-tax  credit of $17  million for other  restructuring
items in the nine-month period was a net before-tax credit of $28 million in the
third quarter.  The credits  included in these net amounts for both periods were
associated  mainly  with  restructuring-related  pension  settlement  gains  for
payments made to terminated  employees.  These credits were partially  offset by
charges for employee and office  relocations,  lease  termination  penalties and
other  items.  These  before-tax  charges for the third  quarter and  nine-month
periods  were $19 million and $43  million,  respectively.  Of the $43  million,
approximately one third remained unpaid at the end of the third quarter. Charges
and credits for these other restructuring costs were classified mainly as either
"operating expense" or "selling,  general and administrative expense." Items are
either  accrued or recognized as incurred under the guidelines of EITF Issue No.
94-3, "Liability Recognition for Certain Employee Termination Benefits and Other
Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)"
or SFAS No. 88, as applicable.

The  company's  net income for nine  months 1999 also  included  its $25 million
share of a restructuring charge recorded by Caltex in the second quarter.


Note 9 - Income Taxes

"Income  Tax  Expense"  for the third  quarter and first nine months of 1999 was
$525 million and $937 million, respectively, compared with $306 million and $855
million for the comparable 1998 periods.  The effective income tax rate for 1999
year to date  increased  to 43 percent  from 36 percent in the 1998 nine months.
The increase in the  effective  tax rates in 1999 was  primarily the result of a
higher  proportion of foreign  income that is taxed at higher  rates.  Partially
offsetting  this  increase  in  effective  rates  in  1999  were  higher  equity
affiliates'  after-tax  earnings as a proportion  of  before-tax  income and tax
credits  connected with the  utilization of capital loss benefits.  Prior period
tax adjustments lowered the effective tax rate in 1998 nine months.


Note 10.  Litigation

The company is a party, along with other oil companies, to numerous lawsuits and
claims,  including  actions  challenging  oil and gas royalty and  severance tax
payments  based on posted prices and actions  related to the use of the chemical
MTBE in certain oxygenated  gasolines.  Plaintiffs may seek to recover large and
sometimes  unspecified  amounts,  and some  matters  may remain  unresolved  for
several  years.  It is not  practical  to estimate a range of possible  loss for
these litigation matters,  and losses could be material with respect to earnings
in any given period.  However,  management is of the opinion that  resolution of
these  matters  will not result in any  significant  liability to the company in
relation to its consolidated  financial position or have a significant effect on
its liquidity.

The company is a defendant in a lawsuit that OXY U.S.A.  brought in its capacity
as successor in interest to Cities Service  Company.  The lawsuit claims damages
resulting from the allegedly improper termination of a tender offer made by Gulf
Oil  Corporation,  acquired by Chevron in 1984,  to purchase  Cities  Service in
1982. A 1996 trial  resulted in a judgment  against the company of $742 million,
including  interest that  continues to accrue while this matter is pending.  The
Oklahoma  Supreme Court  affirmed the lower court's  decision in March 1999, and
accordingly,  the company  recorded in its 1998 results a litigation  reserve of
$637 million  after-tax,  substantially  all of which pertained to this lawsuit,
for the  judgment  and accrued  interest  through  December  1998.  Interest was
accrued  subsequently and will continue to accrue until this matter is resolved.
At September 30, 1999,  the  before-tax  reserve  balance was  approximately  $1
billion.  In March  1999,  the company  filed a petition  for  rehearing  in the
Oklahoma  Supreme Court on the issue of damages and requested oral argument.  In
June 1999, the Oklahoma Supreme Court denied the company's  motion. In July, the
Oklahoma  Supreme  Court  granted  a motion  to stay the  judgment  pending  the
company's  appeal to the U.S.  Supreme  Court.  A petition for certiorari to the
U.S.  Supreme Court was filed in  September.  All briefs have been filed and the
parties are now waiting for the U.S.  Supreme  Court to decide  whether to grant
certiorari.  The ultimate outcome of this matter cannot be presently  determined
with certainty,  and is dependent on the U.S. Supreme Court's  evaluation of the
company's petition.

In a lawsuit in Los Angeles,  California,  brought in 1995, the company and five
other oil companies are  contesting  the validity of a patent  granted to Unocal
Corporation  (Unocal)  for certain  types of  reformulated  gasoline,  which the
company sells in California  during  certain  months of the year.  The first two
phases of the trial were concluded in October and November  1997,  with the jury
upholding the validity of the patent and  assessing  damages at the rate of 5.75
cents per gallon of gasoline sold in  infringement of the patent between March 1
and July 1, 1996. In the third



                                      -12-
<PAGE>

phase of the trial,  the judge  heard  evidence to  determine  if the patent was
enforceable.  In August 1998,  the judge ruled the patent was  enforceable.  The
defendants  filed an appeal in January 1999 and oral  arguments were made before
the court in July 1999.  While the  ultimate  outcome of this  matter  cannot be
determined with certainty,  the company believes  Unocal's patent is invalid and
any unfavorable rulings should be reversed upon appeal. Unocal continues to file
for additional patents for alternate  formulations.  However,  should the jury's
findings and Unocal's patents  ultimately be upheld, the company's exposure with
respect to future  reformulated  gasoline sales would depend on the availability
of alternate formulations and the industry's ability to recover additional costs
of production through prices charged to its customers. The company believes that
its ultimate  exposure in this matter will not  materially  affect its financial
position or  liquidity,  although the costs of resolution  from any  unfavorable
ruling could be material with respect to earnings in any given period.


Note 11. Other Contingencies and Commitments

The U.S. federal income tax and California income tax liabilities of the company
have been settled through 1990 and 1991, respectively.

In June 1997, Caltex Corporation received a claim from the U.S. Internal Revenue
Service  (IRS) for $292 million in excise  taxes,  $140 million in penalties and
$1.6 billion in interest.  The IRS claim  relates to crude oil sales to Japanese
customers  beginning in 1980. Caltex believes the underlying excise tax claim is
wrong and therefore the claim for penalties and interest is wrong.  In May 1998,
Caltex filed a complaint in the United States Court of Federal Claims asking the
Court to hold that Caltex owes nothing on the IRS claim. A decision by the Court
remains pending.  In February 1999,  Caltex renewed a letter of credit for $2.52
billion to the IRS that was required to pursue the claim.  In May 1999,  the IRS
agreed to reduce the  letter of  credit,  which is  guaranteed  by  Chevron  and
Texaco, to $200 million.

Settlement  of open tax years is not  expected to have a material  effect on the
consolidated  financial position or liquidity of the company and, in the opinion
of management,  adequate  provision has been made for income and franchise taxes
for all years under examination or subject to future examination.

The company and its subsidiaries have certain other contingent  liabilities with
respect to guarantees,  direct or indirect,  of debt of affiliated  companies or
others  and  long-term   unconditional  purchase  obligations  and  commitments,
throughput  agreements  and  take-or-pay  agreements,  some of which  relate  to
suppliers' financing arrangements.

The company is subject to loss contingencies  pursuant to environmental laws and
regulations that in the future may require the company to take action to correct
or ameliorate  the effects on the  environment  of prior  disposal or release of
chemical  or  petroleum  substances  by  the  company  or  other  parties.  Such
contingencies  may  exist for  various  sites  including,  but not  limited  to:
Superfund sites and refineries,  chemical plants, oil fields,  service stations,
terminals and land development  areas,  whether  operating,  closed or sold. The
amount of such future cost is indeterminable  due to such factors as the unknown
magnitude  of  possible  contamination,  the  unknown  timing  and extent of the
corrective  actions that may be required,  the  determination  of the  company's
liability in  proportion  to other  responsible  parties and the extent to which
such costs are  recoverable  from third parties.  While the company has provided
for known environmental  obligations that are probable and reasonably estimable,
the amount of future  costs may be  material  to results  of  operations  in the
period in which they are recognized.  The company does not expect these costs to
have a material  effect on its  consolidated  financial  position or  liquidity.
Also, the company does not believe its obligation to make such  expenditures has
had or will have any significant  impact on the company's  competitive  position
relative to other domestic or international petroleum or chemical concerns.

The company  utilizes various  derivative  instruments to manage its exposure to
price  risk  stemming  from  its  integrated  petroleum  activities.  All  these
instruments  are  commonly  used  in oil  and  gas  trading  activities  and are
relatively  straightforward,  involve little  complexity and are of a short-term
duration.  Most of the  activity  in these  instruments  is  intended to hedge a
physical  transaction;  hence,  gains and losses arising from these  instruments
offset,  and are  recognized  concurrently  with,  gains  and  losses  from  the
underlying  transactions.  The company  believes  it has no  material  market or
credit risks to its operations,  financial  position or liquidity as a result of
its commodities and other  derivatives  activities,  including  forward exchange
contracts and interest rate swaps.  Its control  systems are designed to monitor
and manage its  financial  exposures in  accordance  with  company  policies



                                      -13-
<PAGE>

and  procedures.  The results of operations  and  financial  position of certain
equity affiliates may be affected by their business activities involving the use
of derivative instruments.

The company's  operations,  particularly oil and gas exploration and production,
can be affected by changing economic,  regulatory and political  environments in
the various  countries,  including the United States,  in which it operates.  In
certain  locations,  host  governments have imposed  restrictions,  controls and
taxes, and, in others,  political  conditions have existed that may threaten the
safety of employees and the  company's  continued  presence in those  countries.
Internal unrest or strained  relations between a host government and the company
or other  governments may affect the company's  operations.  Those  developments
have, at times,  significantly  affected the company's  related  operations  and
results, and are carefully considered by management when evaluating the level of
current and future activity in such countries.

Areas in which the company has significant operations include the United States,
Canada,   Australia,   United  Kingdom,  Republic  of  Congo,  Angola,  Nigeria,
Democratic  Republic of Congo, Papua New Guinea,  China,  Indonesia,  Venezuela,
Argentina  and  Thailand.  The  company's  Caltex  affiliates  have  significant
operations in Indonesia, Korea, Australia, Thailand, the Philippines, Singapore,
and South Africa. The company's Tengizchevroil affiliate operates in Kazakhstan.


Note 12. Issuance of New Accounting Standards

In June 1998, the Financial  Accounting  Standards Board (FASB) issued Statement
No. 133,  "Accounting for Derivative  Instruments and Hedging  Activities"  (FAS
133).  In June 1999,  the FASB issued  Statement  No. 137,  which  deferred  the
effective  date of FAS  133,  making  the  statement  effective  for all  fiscal
quarters of fiscal years beginning  after June 15, 2000,  with earlier  adoption
encouraged.  The  company  anticipates  adoption  of the  provisions  of FAS 133
effective  January  1,  2001.  The  company  and its  affiliates  are  currently
evaluating  implementation of FAS 133 and the effects the Statement will have on
its financial statements and disclosures.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

               Third Quarter 1999 Compared With Third Quarter 1998
         And First Nine Months 1999 Compared With First Nine Months 1998

Financial Results
- -----------------
Net  income  for the  third  quarter  of 1999 was $582  million  ($0.88  diluted
earnings  per share),  an increase of 26 percent from net income of $461 million
($0.70  diluted  earnings  per share) for the 1998  third  quarter.  In the 1999
quarter, net income included special charges of $120 million,  compared with net
benefits of $75 million in the 1998 third quarter.  Special  charges in the 1999
third quarter included asset write-downs of $79 million,  $31 million for losses
on asset dispositions and $10 million for environmental remediation. In the 1998
quarter,  the company  received $105 million of proceeds from several  insurance
settlements  related to environmental cost recovery claims and recognized a gain
of $18 million  from the sale of a U.S. oil and gas  property.  These gains were
partially offset by the company's $43 million share of the costs associated with
the  reorganization of management and  administration  functions of Caltex,  the
company's 50 percent-owned  equity affiliate,  and a provision of $5 million for
environmental remediation.  Excluding special items, 1999 third quarter earnings
were $702 million, an 82 percent increase from earnings of $386 million in 1998.

Net income for the first nine months of 1999 was $1.261  billion  ($1.91 diluted
earnings per share), down from $1.545 billion ($2.35 diluted earnings per share)
for the 1998 nine months.  Net income for the year-to-date  periods included net
special charges of $206 million in 1999 and net special benefits of $103 million
in 1998.  Nine-month 1999 net income was reduced by charges for restructuring of
$146  million,  asset  write-downs  of $122 million,  environmental  remediation
provisions  of $96  million and  regulatory  issues of $23  million.  These were
partially  offset by gains of $121  million  from asset sales and the  favorable
effects of $60 million from  prior-year tax  adjustments.  The 1998  nine-months
benefited  $190  million  from  tax  adjustments  and  $80  million  from  claim
settlements, partially offset by asset write-downs of $68 million, restructuring
costs of $43  million,  losses on asset sales of $38  million and  environmental
remediation  provisions of $18 million.  Excluding these special  charges, nine
month  earnings were $1.467  billion in 1999 compared with $1.442 billion in the
first nine months of 1998.

Net income also included foreign exchange losses of $7 million in the 1999 third
quarter  compared with losses of $26 million in the third quarter of 1998.  Year
to date, foreign exchange  fluctuations reduced earnings $48 million in 1999 and
increased  earnings  $24  million  in 1998.  Changes  between  periods  occurred
primarily in Caltex's  Australian  operations  and in Chevron's  Australian  and
Canadian exploration and production businesses.

Chevron's worldwide  exploration and production  (upstream) earnings,  excluding
special items,  improved in the 1999 quarter,  benefiting  from higher crude oil
prices and from increases in production in  international  areas.  The company's
average U.S.  crude oil  realizations  of $18.11 per barrel in the third quarter
1999 were nearly $7 per barrel  higher  than the same period last year.  Average
U.S.  natural gas  realizations  of $2.48 per thousand  cubic feet were 56 cents
higher than in the 1998 third quarter.

Chevron's  refining,   marketing  and  transportation   (downstream)  businesses
suffered  significantly lower earnings in the third quarter,  compared with last
year. The company's U.S. downstream business experienced narrower margins as the
increases in crude oil prices outpaced refined products sales  realizations.  In
addition,  continuing  repairs to operating  units at the Richmond,  California,
refinery  had an  adverse  impact  on  earnings.  Earnings  from  the  company's
international  downstream  operations  remained  depressed in the third  quarter
1999,  primarily as earnings from the company's Caltex affiliate continued to be
impacted  by weak  refined  products  margins  in the  Asia-Pacific  region.  In
addition, in the third quarter 1999 the company recorded lower earnings from its
international shipping operations.

Operating Environment and Outlook
- ---------------------------------
Chevron's  earnings are affected  significantly  by fluctuations in the price of
crude oil and natural gas.  The average  spot price for West Texas  Intermediate
(WTI),  a  benchmark  crude oil,  was  $21.73  per barrel for the  quarter - the
highest  level  since the first  quarter of 1997 and 54 percent  higher than the
same period last year. For the first nine months of 1999, the average spot price
of WTI was $17.58 per barrel,  18 percent higher than the same period last year.
Crude oil prices  remain at levels  higher  than last year,  as the price of WTI
averaged $22.64 per barrel during



                                      -15-
<PAGE>

October  1999.  Average U.S.  natural gas prices for the third quarter 1999 were
significantly  higher than last year's quarter.  Chevron's average U.S. natural
gas realizations increased 29 percent to $2.48 per thousand cubic feet.

Chevron's  third quarter 1999 worldwide net oil equivalent  production was 1.545
million  barrels per day, an increase of 4 percent over the third  quarter 1998.
Liquids production from  international  operations  continues to increase,  up 3
percent in the third  quarter to 792,000  barrels per day and 5 percent  year to
date,  compared with the  corresponding  periods last year. The company  expects
international  liquids  production to increase  during the fourth  quarter 1999,
primarily as a result of the  acquisition of Petrolera  Argentina San Jorge,  an
oil and gas exploration and production  company in Argentina,  late in September
1999.

The rise in crude oil and natural gas prices were the primary  driver for higher
comparative  earnings for the company's  exploration and production  operations,
offsetting  increases  in  exploration  expenses.  While  prices are expected to
remain  volatile  during the fourth  quarter 1999,  they are likely to remain at
levels  exceeding  last year's  fourth  quarter if cutbacks in OPEC and non-OPEC
production continue.

Certain countries in which Chevron has producing  operations have mandated crude
oil production cuts to help boost sales prices of crude oil. To date,  Chevron's
production has not been materially affected by these reductions, and the company
believes  that  in the  current  industry  environment,  the net  effect  of any
curtailments  directed by host countries would not be significant to its overall
production  levels.  However,  such  curtailments  or limits may have an adverse
effect  on the level of new  production  from  current  and  future  development
projects.  In  addition,   civil  unrest,  political  uncertainty  and  economic
conditions may affect the company's  producing  operations.  Community  protests
have disrupted the company's  production in the past,  most recently in Nigeria.
The company continues to monitor  developments closely in the countries in which
it operates.

Higher prices for crude oil  contributed  to narrower  margins in the downstream
business,  except on the U.S. West Coast where  industry  margins  strengthened.
Operational problems at the company's Richmond,  California,  refinery prevented
Chevron  from fully  realizing  the  benefits of the higher  west coast  refined
products  margins.   Refinery  problems  restricted   production  of  oxygenated
gasoline,  mandated  by  California,  making it  necessary  for the  company  to
purchase  products from third parties to meet its customers'  requirements.  The
company  estimates  these  refinery  upsets  adversely  impacted  third  quarter
earnings by about $40 million.  U.S.  downstream  earnings in the fourth quarter
1999 will continue to be affected by lower  production  capacity at the Richmond
refinery,  although the impact is expected to be less than in the third quarter.
Repairs to a fluid  catalytic  cracker were  completed by mid-August  1999,  but
repairs to a  hydrocracker  are not expected to be  completed  before the end of
1999. The company has business  interruption  insurance  coverage and expects to
recover  some  of the  losses  attributable  to the  incidents  at its  Richmond
refinery. In addition, the company continues to pursue business interruption and
property  damage claims for 1998 storm damages to its  Pascagoula,  Mississippi,
refinery. The timing and amount of recovery from these claims are uncertain.

Caltex operations in the Far East,  particularly Korea, continued to suffer from
weak  refined  product  margins  -resulting  from  higher  feedstock  costs  and
competitive  price  discounting - and have failed to fully recover  rising crude
oil  costs in the  prices  for  refined  products.  Caltex  may  continue  to be
adversely  affected by these  conditions  through the  remainder  of 1999 as the
Asia-Pacific markets continue to experience surplus  manufacturing  capacity and
related oversupply conditions.

Earnings of Chevron's  chemicals  operations  are  expected to remain  depressed
because of continued  downward  pressure on industry margins as higher feedstock
costs are not yet being fully  reflected in commodity  chemical  product prices.
The low  margins are a result of industry  manufacturing  over-capacity,  higher
prices for feedstocks and reduced Asian demand for U.S.-manufactured products.

Although the recent  increases in crude oil and natural gas prices have improved
the overall economic environment in which the company operates,  Chevron remains
focused on efforts to improve its efficiency.  On a per-barrel basis,  operating
expenses,  after  adjustments  for special items and  operations  that have been
disposed  of,  were $5.01 per barrel  for the first  nine  months,  down about 7
percent from the 1998 comparable period. Excluding the costs associated with the
company's  growth  components -  international  exploration  and  production and
international  chemicals - the  company's  cost  structure  declined  about $400
million below last year.

Significant Developments
- ------------------------
In September,  Chevron acquired 100 percent of Petrolera Argentina San Jorge, an
oil and gas  exploration  and producing  company in Argentina.  Included in this
acquisition  was an interest in the major export  pipeline to the Atlantic coast
of Argentina  and  exploration  acreage in key  petroleum  basins in  Argentina,
Colombia,  Ecuador,  Peru,  Bolivia and Chile. San Jorge's recent gross operated
production  reached  78,000  barrels of oil and 40 million cubic feet of gas per
day. In October,  this  company  announced a new oil  discovery in the Rio Negro
Province, Argentina. The discovery, the seventh since January 1999, tested 3,880
barrels per day of 39-degree API oil.  Chevron holds a 37.5 percent  interest in
this discovery.

Also in October,  Chevron took over  operatorship in Thailand of Block B8/32, in
which it acquired an approximate 52 percent  interest  earlier this year.  Gross
production  of natural gas reached  over 140 million  cubic feet per day in late
September,  while  production of liquids is expected to reach 30,000 barrels per
day by the end of this year.

In  the  Caspian  Sea  area,   gross   liquids   production   at  the  company's
Tengizchevroil joint venture in Kazakhstan averaged over 215,000 barrels per day
in the third  quarter,  up from  183,000  barrels per day in last  year's  third
quarter.  Essential to the goal of expanding production from the Tengiz field to
700,000  barrels  per  day by  2010  is the  completion  of the  pipeline  under
construction  by the  Caspian  Pipeline  Consortium,  in which  Chevron has a 15
percent interest.  Commitments exceeding $1.5 billion for material purchases and
contract  services  have  been made to date to build  this link from the  Tengiz
field to the Black Sea.  Over $500 million has been expended on the project thus
far. Pipeline completion is scheduled for 2001.

Chevron was appointed the Managing Sponsor of a six-company  consortium that was
selected by the Governments of Benin,  Ghana,  Nigeria,  and Togo to develop the
West African Gas Pipeline. This pipeline will be developed to link gas producers
in  Western  Nigeria  with  power  generation  plants  in the  other  countries,
initially delivering an estimated 120 million cubic feet of natural gas per day.
This pipeline will help reduce air pollution by reducing gas flaring  associated
with existing oil production in Nigeria and by delivering natural gas to replace
more polluting fuels.

Chevron  announced in September a  significant  natural gas  discovery  offshore
Western  Australia  at the  Geryon  prospect.  Geryon  is  operated  by the West
Australian  Petroleum Pty. Ltd. Joint Venture,  of which Chevron is a 25 percent
participant.

In August,  Chevron and two other partners  announced they had reached agreement
to jointly develop The Athabasca Oil Sands Project in Alberta,  Canada,  subject
to final corporate  approvals of each of the partners.  The project is scheduled
to begin  producing  150,000  barrels of synthetic crude oil per day in 2002 and
Chevron will have a 20 percent stake.

Year 2000 Problem
- -----------------
The Year 2000 problem is the result of computer systems and other equipment with
embedded  chips or  processors  using two digits,  rather than four, to define a
specific year and potentially  being unable to process  accurately  certain data
before,  during  or  after  2000.  This  could  result  in  system  failures  or
miscalculations, causing disruptions to various activities and operations.

Chevron has established a  corporate-level  Year 2000 project team to coordinate
the efforts of teams in the company's operating units and corporate  departments
to address the Year 2000 issue in three  major  areas:  information  technology,
embedded systems and supply chain.  Information technology includes the computer
hardware,  systems  and  software  used  throughout  the  company's  facilities.
Embedded systems exist in automated equipment and associated software, which are
used  in  the  company's  exploration  and  production  facilities,  refineries,
transportation operations, chemical plants and other business operations. Supply
chain  includes the third  parties with which  Chevron  conducts  business.  The
company also is monitoring  the Year 2000 efforts of its equity  affiliates  and
joint-venture partners.  Progress reports on the Year 2000 project are presented
regularly to the  company's  senior  management  and  periodically  to the Audit
Committee of the company's Board of Directors.

The company is addressing the Year 2000 issue in three overlapping  phases:  (1)
identification  and assessment of all critical  equipment,  software systems and
business  relationships  that may require  modification or replacement  prior to
2000;  (2)  resolution  of critical  items  through  remediation  and testing of
modifications,  replacement,  or



                                      -17-
<PAGE>

development of alternative  business processes;  and (3) development and testing
of contingency  and business  continuation  plans for critical items to mitigate
any disruptions to the company's operations.

Chevron's  plans called for all critical items to be addressed prior to 2000. By
September  30,  1999  all  three  phases  of  Chevron's   Year  2000  project  -
identification and assessment, remediation and testing, and contingency planning
- - were essentially complete. Because of the scope of its operations, the company
believes it is impractical to eliminate all potential Year 2000 problems  before
they arise. As a result, the company expects that for non-mission-critical items
and those  mission-critical  items for which  temporary "work arounds" have been
developed, Year 2000 remedial efforts will continue into the year 2000.

In the normal  course of  business,  the company  has  developed  and  maintains
extensive  contingency plans to respond to equipment  failures,  emergencies and
business  interruptions.  However,  contingency planning for Year 2000 issues is
complicated by the  possibility of multiple and  simultaneous  incidents,  which
could  significantly  impede efforts to respond to emergencies and resume normal
business functions.  Such incidents may be outside of the company's control, for
example, if mission-critical third parties do not successfully address their own
material Year 2000 problems.

The company has enhanced  existing  plans,  where  necessary,  and in some cases
developed  new  plans  specifically  designed  to  mitigate  the  impact  on its
operations of potential  failures  relating to the Year 2000 issue.  These plans
are designed to continue safe operations,  protect the environment,  protect the
company's  assets and enable the resumption of any  interrupted  operations in a
timely and efficient  manner.  The company has dedicated  significant  resources
toward validating that contingency plans developed in individual operating units
are consistent and complementary across the company.  Additionally,  the company
is implementing  plans designed to mitigate the risk of supply outages occurring
in its businesses  that may result from potential  increases in customer  demand
prior to January 1, 2000. In the third quarter  1999,  the company  successfully
completed  a test of its  Corporate  Year 2000  Information  Center,  which will
monitor the Year 2000 status of the  company's  facilities  around the world.  A
variety of potential  Year 2000  scenarios  were  developed.  The company tested
processes and procedures to manage both the  information  flow and its responses
to these different situations.  As part of its contingency planning, the company
will place  emergency  response teams at key locations  around the world in late
December and early January.

The company  utilizes  both  internal  and  external  resources in its Year 2000
efforts.  The cumulative total cost to achieve Year 2000 compliance is currently
estimated at $175 million,  mostly for  expense-type  items, not all of which is
incremental  to the company's  operations.  Approximately  $145 million had been
spent through  September 30, 1999. The majority the future  expenditures will be
incurred  during  the  remainder  of 1999 with some  expenditures  in 2000.  The
foregoing  amounts  include the  company's  share of  expenditures  by its major
affiliates.

As part of the Securities and Exchange  Commission's  reporting  requirements on
the Year 2000  problem,  companies  must  include a  description  of their "most
reasonably  likely  worst-case  scenarios" from potential Year 2000 issues.  For
Chevron,  its business  diversity  is expected to reduce the risk of  widespread
disruptions to its worldwide  operations from Year 2000-related  incidents.  The
company does not expect unusual risks to public safety or to the  environment to
arise from potential Year 2000-related failures. While the company believes that
the impact of any individual Year 2000 failure most likely will be localized and
limited to specific facilities or operations, it is not yet able to fully assess
the likelihood of significant business interruptions occurring in one or more of
its operations around the world. Such  interruptions  could delay  manufacturing
and  delivery  of refined  products  and  chemicals  products  by the company to
customers.  The company could also face  interruptions in its ability to produce
crude oil and natural  gas.  While not  expected,  failures to address  multiple
critical  Year  2000  issues,   including  failures  to  implement   appropriate
contingency plans in a timely manner,  could materially and adversely affect the
company's  results of operations or liquidity in any one period.  The company is
currently  unable to predict the aggregate  financial or other  consequences  of
such potential interruptions.

The  foregoing  disclosure  is  based  on the  company's  current  expectations,
estimates  and  projections,  which  could  ultimately  prove to be  inaccurate.
Because of  uncertainties,  the  actual  effects  of Year 2000  problems  on the
company may be different  from the company's  current  assessment.  Factors that
could affect the company's ability to be Year 2000 compliant by the end of 1999,
many of which are outside its control,  include:  failures to achieve compliance
by customers,  suppliers,  governmental entities and others, and failures by the
company to identify all critical  Year 2000  issues,  or to develop  appropriate
contingency  plans for all Year 2000  issues  that  ultimately  may



                                      -18-
<PAGE>

arise.  The  foregoing  disclosure  is made  pursuant to the  Federal  Year 2000
Information and Readiness Disclosure Act.

Other Contingencies and Significant Litigation
- ----------------------------------------------
The company is a defendant in a lawsuit that OXY U.S.A.  brought in its capacity
as successor in interest to Cities Service  Company.  The lawsuit claims damages
resulting from the allegedly improper termination of a tender offer made by Gulf
Oil  Corporation,  acquired by Chevron in 1984,  to purchase  Cities  Service in
1982. A 1996 trial  resulted in a judgment  against the company of $742 million,
including  interest that  continues to accrue while this matter is pending.  The
Oklahoma  Supreme Court  affirmed the lower court's  decision in March 1999, and
accordingly,  the company recorded in 1998 results a litigation  reserve of $637
million after-tax, substantially all of which pertained to this lawsuit, for the
judgment  and accrued  interest  through  December  1998.  Interest  was accrued
subsequently  and will  continue  to accrue  until this matter is  resolved.  At
September 30, 1999, the before-tax reserve balance was approximately $1 billion.
In March 1999,  the  company  filed a petition  for  rehearing  in the  Oklahoma
Supreme Court on the issue of damages and requested oral argument. In June 1999,
the Oklahoma  Supreme Court denied the company's  motion.  In July, the Oklahoma
Supreme Court granted a motion to stay the judgment pending the company's appeal
to the U.S.  Supreme Court. A petition for certiorari to the U.S.  Supreme Court
was filed in  September.  All  briefs  have been filed and the  parties  are now
waiting for the U.S.  Supreme Court to decide whether to grant  certiorari.  The
ultimate  outcome of this matter cannot be presently  determined with certainty,
and is  dependent  on the  U.S.  Supreme  Court's  evaluation  of the  company's
petition.

In a lawsuit in Los Angeles,  California,  brought in 1995, the company and five
other oil companies are  contesting  the validity of a patent  granted to Unocal
Corporation  (Unocal)  for certain  types of  reformulated  gasoline,  which the
company sells in California  during  certain  months of the year.  The first two
phases of the trial were concluded in October and November  1997,  with the jury
upholding the validity of the patent and  assessing  damages at the rate of 5.75
cents per gallon of gasoline sold in  infringement of the patent between March 1
and July 1, 1996. In the third phase of the trial,  the judge heard  evidence to
determine  if the  patent is  enforceable,  and in August  1998,  ruled that the
patent was enforceable.  The defendants filed an appeal in January 1999 and oral
arguments were made before the court in July 1999. While the ultimate outcome of
this matter cannot be determined with certainty,  the company believes  Unocal's
patent is invalid and any  unfavorable  rulings  should be reversed upon appeal.
Unocal  continues to file for  additional  patents for  alternate  formulations.
However,  should the jury's findings and Unocal's patents  ultimately be upheld,
the company's exposure with respect to future reformulated  gasoline sales would
depend on the availability of alternate  formulations and the industry's ability
to recover the  additional  costs of production  through  prices  charged to its
customers.  The company believes that its ultimate  exposure in this matter will
not materially affect its financial position or liquidity, although the costs of
resolution  from any  unfavorable  ruling  could be  material  with  respect  to
earnings in any given period.

In June 1997, Caltex Corporation received a claim from the U.S. Internal Revenue
Service  (IRS) for $292 million in excise  taxes,  $140 million in penalties and
$1.6 billion in interest.  The IRS claim  relates to crude oil sales to Japanese
customers  beginning in 1980. Caltex believes the underlying excise tax claim is
wrong and therefore the claim for penalties and interest is wrong.  In May 1998,
Caltex filed a complaint in the United States Court of Federal Claims asking the
Court to hold that Caltex owes nothing on the IRS claim. A decision by the Court
remains pending.  In February 1999,  Caltex renewed a letter of credit for $2.52
billion to the IRS that was  required  to pursue the claim.  In May 1999 the IRS
agreed to reduce the  letter of  credit,  which is  guaranteed  by  Chevron  and
Texaco, to $200 million.

The company is a party to numerous  lawsuits and claims,  including,  along with
other oil companies,  actions  challenging oil and gas royalty and severance tax
payments  based on posted  prices and others  related to the use of the chemical
MTBE in certain oxygenated  gasolines.  The company believes that the resolution
of these matters will not materially affect its financial position or liquidity,
although costs  associated with their  resolution could be material with respect
to earnings in any given period.

The company  utilizes various  derivative  instruments to manage its exposure to
price  risk  stemming  from  its  integrated  petroleum  activities.  All  these
instruments  are  commonly  used  in oil  and  gas  trading  activities  and are
relatively  straightforward,  involve little  complexity and are of a short-term
duration.  Most of the  activity  in these  instruments  is  intended to hedge a
physical  transaction;  hence,  gains and losses arising from these  instruments
offset,  and are  recognized  concurrently  with,  gains  and  losses  from  the
underlying  transactions.  The company  believes  it has no  material  market or
credit risks to its operations,  financial  position or liquidity as a result of
its



                                      -19-
<PAGE>

commodities  and  other  derivatives  activities,   including  forward  exchange
contracts and interest rate swaps.  Its control  systems are designed to monitor
and manage its  financial  exposures in  accordance  with  company  policies and
procedures.  The results of operations and financial  position of certain equity
affiliates  may be affected by their  business  activities  involving the use of
derivative instruments.

The company's  operations,  particularly oil and gas exploration and production,
can be affected by changing economic,  regulatory and political  environments in
the  various  countries,  including  the United  States,  in which it  operates.
Political  uncertainty  and civil  unrest may, at times,  threaten the safety of
employees  and  the  company's  continued  presence  in  a  country.  Management
carefully  considers  these  factors  when  evaluating  the level of current and
future activity in such countries.

The company and its affiliates  continue to review and analyze their  operations
and may close, abandon, sell, exchange, acquire or restructure assets to achieve
operational   or  strategic   benefits  and  to  improve   competitiveness   and
profitability. In addition, the company receives claims from, and submits claims
to, customers,  trading partners,  host governments,  contractors,  insurers and
suppliers.  The amounts of these claims,  individually and in the aggregate, may
be significant  and take lengthy  periods to resolve.  The company also suspends
the costs of exploratory  wells pending a final  determination of the commercial
potential of the related oil and gas fields.  The ultimate  disposition of these
well costs is  dependent  on the  results  of future  drilling  activity  and/or
development decisions.  If the company decides not to continue development,  the
costs of these wells are expensed.  These activities,  individually or together,
may result in gains or losses in future periods.

Employee Staff Reductions and Restructurings
- --------------------------------------------
During the second quarter of 1999,  Chevron began implementing a staff reduction
program  and  other  restructuring  activities  across  the  company.  While the
programs affect the activities of all the company's business  segments,  most of
the net costs relate to the termination and relocation of U.S.-based employees.

For the nine-month 1999 period, net income included  restructuring costs of $141
million, including termination benefits for approximately 3,100 employees. These
restructuring   costs   include   accrued   employee    termination    benefits,
restructuring-related pension settlement gains and other items. Also included is
$25 million for Chevron's share of restructuring  charges recorded by its Caltex
affiliate.  The net-income  effect of these costs in millions of dollars and the
estimated number of employees  (excluding Caltex employees) to be terminated are
presented by business segment in the following table:

</TABLE>

The staff  reductions  began in the second quarter 1999 and will be completed by
the end of the second  quarter  2000.  The company  will also  continue to incur
restructuring  costs that benefit  ongoing  operations. In addition,  actuarial
gains  will be  recognized  that are  associated  with  payments  made  from the
company's  pension  plans for the  terminated  employees.  These  items  will be
included in net income as they occur.

Review of Operations
- --------------------
Total  revenues  for the quarter were $10.2  billion,  an increase of 32 percent
from $7.7 billion in last year's third quarter. For the nine-month period, total
revenues were $25.6 billion,  up 10 percent from $23.3 billion in the comparable
1998  period.   Revenue  increases  were  mainly  the  result  of  higher  sales
realizations for refined products, crude oil and natural gas.

                                      -20-
<PAGE>

Total  "Operating  expenses" and "Selling,  general and  administrative"  (SG&A)
expenses,  adjusted  for special  items,  were $1.449  billion in the 1999 third
quarter  compared  with $1.632  billion in last year's third  quarter.  For nine
months,  total operating  expenses and SG&A expenses,  excluding  special items,
declined  $164  million  to $4.557  billion  despite  an  increase  in crude oil
production.  The company  continues  to keep tight  control  over its  operating
expenses.

Third quarter 1999 "Depreciation, depletion and amortization" (DD&A) expenses of
$767  million  were $204  million  higher than the 1998 third  quarter.  For the
nine-month period, DD&A expenses of $1.966 billion were $292 million higher than
the 1998 period.  DD&A related to asset write-downs  increased  expenses by $156
million  for the third  quarter  and $211  million  for the first nine months of
1999.

"Income  Tax  Expense"  for the third  quarter and first nine months of 1999 was
$525 million and $937 million, respectively, compared with $306 million and $855
million for the comparable 1998 periods.  The effective income tax rate for 1999
year to date  increased  to 43 percent  from 36 percent in the 1998 nine months.
The increase in the  effective  tax rates in 1999 was  primarily the result of a
higher  proportion of foreign  income that is taxed at higher  rates.  Partially
offsetting  the  increase  in  effective   rates  in  1999  were  higher  equity
affiliates'  after-tax  earnings as a proportion  of  before-tax  income and tax
credits  connected with the  utilization of capital loss benefits.  Prior period
tax adjustments lowered the effective tax rate in 1998 nine months.

Worldwide  exploration  and  production net income was $555 million in the third
quarter of 1999,  more than double the $263 million for the  corresponding  1998
period.  Net income of $1.037  billion  in the first nine  months of 1999 was 30
percent higher than the $798 million earned in the 1998 period. U.S. exploration
and production  third quarter 1999 net income was $233 million,  more than twice
the $102 million earned in last year's third quarter.  Nine-month net income was
$378 million in 1999, compared with $293 million earned in the 1998 nine months.
Special items for the 1999 third quarter included write-downs of $45 million for
oil and gas  properties in the Gulf of Mexico.  In addition to the third quarter
write-downs, earnings in the 1999 nine months were reduced by special charges of
$26 million for  restructuring  costs, $23 million for litigation and regulatory
issues and $3 million for environmental remediation provisions. The 1998 quarter
and  year-to-date  net income included  special benefits of $18 million from the
sale of an oil and gas property in the U.S.  Gulf of Mexico.  Excluding  special
items in all  periods,  1999 third  quarter  earnings  more than tripled to $278
million.  Nine-month  earnings were $475 million,  compared with $275



                                      -22-
<PAGE>

million in 1998.  The improved 1999 results were  primarily the result of higher
crude oil and natural gas prices and lower operating expenses.

The company's  average 1999 third quarter U.S. crude oil  realizations of $18.11
per barrel increased $6.80 over last year's third quarter.  Average U.S. natural
gas  realizations of $2.48 per thousand cubic feet were 56 cents higher than the
1998 third quarter.  On a year-to-date  basis,  1999 crude oil realizations were
$14.20 per  barrel,  21 percent  higher  than the $11.72 per barrel  obtained in
1998, and natural gas prices were $2.06 per thousand cubic feet, slightly higher
than the $2.03 per thousand  cubic feet obtained last year. The higher crude oil
prices were  primarily  a result of  production  cutbacks  by OPEC and  non-OPEC
producing countries.

Net U.S.  liquids  production  averaged  321,000  barrels  per day in the  third
quarter of 1999 and 313,000 barrels per day for the first nine months.  In 1998,
liquids  production  averaged  323,000  barrels per day in the third quarter and
332,000  barrels  per day for the  year-to-date  period.  Net U.S.  natural  gas
production  was 1.664  billion  cubic feet per day in the 1999 third quarter and
1.659  billion  cubic feet per day for nine months,  compared with 1.703 billion
cubic feet per day and 1.765 billion cubic feet per day,  respectively,  for the
corresponding 1998 periods. The lower U.S. production of liquids and natural gas
resulted from new production  having been more than offset by property sales and
normal  field  production  declines in both the third  quarter-  and  nine-month
periods.  Also a factor in the production  volume change between periods was the
adverse effect on third quarter 1998 production  caused by September 1998 storms
in the Gulf of Mexico.

International  exploration  and production net income for the 1999 third quarter
was $322 million,  double the $161 million  earned in the third quarter of 1998.
Net income of $659  million in the first nine months of 1999 was 30 percent more
than the $505 million earned in the 1998 period.  There were no special items in
the third  quarters of 1999 or 1998.  There was no impact from special  items on
earnings in the 1999 nine  months as a gain on an asset sale offset  charges for
restructuring  costs.  Earnings in the 1998 nine  months  were  reduced a net $3
million when a loss related to an asset swap was mostly  offset by favorable tax
adjustments.  The increase in 1999 earnings reflected significantly higher crude
oil and  natural  gas prices and higher  crude-oil  liftings  compared  with the
corresponding 1998 periods. Higher exploration expenses, including a $42 million
write-off of an exploratory well in China, reduced earnings by about $70 million
in the 1999 third  quarter,  compared with the 1998 quarter.  For the nine-month
periods,  higher  exploration  expenses in 1999 partially offset the benefits of
higher crude oil and natural gas prices by approximately $55 million.

The company's 1999 average third quarter international crude oil realizations of
$19.63  per  barrel  increased  $8.16,  or 71  percent,  compared  with the 1998
quarter.  Average third quarter  international natural gas realizations of $1.89
per  thousand  cubic feet were 12 cents,  or 6 percent,  lower than in the third
quarter of last year. On a year-to-date  basis, 1999 crude oil realizations were
$15.11 per  barrel,  23 percent  higher  than the $12.26 per barrel  obtained in
1998.  Natural gas prices  were $1.83 per  thousand  cubic feet,  a decline of 5
percent from $1.93 per thousand cubic feet last year.

Net international liquids production of 792,000 barrels per day increased 24,000
barrels per day from last year's third quarter,  and nine months  production was
799,000  barrels per day  compared  with  759,000  barrels per day in 1998.  The
year-to-date  production  increases  were  primarily  in Angola  and  Kazakhstan
partially offset by declines in Australia and Nigeria.

Net natural gas  production  for the 1999 third quarter  increased 46 percent to
929 million  cubic feet per day, and  increased 41 percent to 867 million  cubic
per day for nine months.  The increases  reflect  higher  production in the U.K.
North Sea - where the  Britannia  Field  began  producing  in  August  1998;  in
Thailand - as a result of the company's  Rutherford-Moran  acquisition  in early
1999; and in Kazakhstan and western Canada.

Earnings also included  foreign  exchange losses of $3 million in the 1999 third
quarter  compared with gains of $8 million in the third quarter of 1998. Year to
date,  foreign  exchange  fluctuations  reduced earnings $31 million in 1999 and
increased  earnings $31 million in 1998.  These  changes  occurred  primarily in
Chevron's Australian and Canadian businesses.

Worldwide refining,  marketing and transportation operations reported net income
of $76 million in the 1999 third quarter,  about half of the $142 million earned
in last year's third quarter. The 1999 nine-month net income was $415 million, a
31 percent decrease from the corresponding 1998 period. U.S. refining, marketing
and



                                      -23-

transportation  net income was $97 million in the 1999 third  quarter,  compared
with $188 million in the 1998 quarter.  Nine-month  net income for 1999 was $288
million  compared with $458 million in the 1998 nine months.  Net income for the
third quarter of 1999 included special charges of $10 million for  environmental
remediation. There were no special items in the 1998 third quarter. On a year to
date  basis,  1999 net  income  was  reduced  by a net  charge  of $14  million.
Provisions for environmental  remediation ($65 million) and reorganization costs
($24 million), were partially offset by a gain on the sale of pipeline interests
($75 million). Nine-month 1998 results were reduced $13 million by environmental
remediation provisions.

The company's  refined  products margins declined as raw material cost increases
outpaced  product  realizations.  In addition,  unplanned  unit shutdowns at the
Richmond,   California,   refinery  had  an  adverse  impact  on  earnings.  The
hydrocracker is under repair from damages incurred in a March 1999 fire, and the
fluid  catalytic  cracker was taken out of operation  for repairs in the current
quarter  as  well.  Third  quarter  1998  earnings  were  reduced  by  insurance
deductible costs for damages to the Pascagoula,  Mississippi, refinery and other
facilities resulting from Hurricane Georges.

Total refined  product  sales volumes were 1.357 million  barrels per day in the
third quarter of 1999, up 3 percent from the comparable  quarter last year. Year
to date refined  products sales volumes of 1.305 million barrels per day were up
4 percent from 1.254 million  barrels per day last year.  Chevron-branded  motor
gasoline  sales also  improved by 3 percent over last year's  quarter to 559,000
barrels  per day.  Through  the first nine  months of this year,  branded  motor
gasoline sales have increased 5 percent when compared with the same 1998 period.

The company's  average refined product prices were $29.48 per barrel in the 1999
third quarter, compared with $21.91 in the 1998 quarter. Average refined product
prices  were  $25.43  and $22.73 in the  year-to-date  periods of 1999 and 1998,
respectively.

International  refining,  marketing and transportation  operations  incurred net
losses  of $21  million  and $46  million  in the third  quarter  1999 and 1998,
respectively.  The net loss for the third quarter of 1999 included the company's
$31  million  share of  Caltex's  loss  from the sale of its  investment  in the
Japanese refiner, Koa Oil Company. The 1998 third quarter included the company's
$43  million  share of costs  associated  with the  reorganization  of  Caltex's
management  and  administration  functions.  Net  income in the 1999  nine-month
period was $127  million,  compared with $146 million in the  comparable  period
last year. In addition to the third quarter  special item discussed  above,  the
1999  nine-month  period  included a special  gain of $60 million for  favorable
Korean  tax  adjustments,  partially  offset by $30  million  for  restructuring
charges attributable to both Caltex and Chevron operations. Results for the 1998
nine months  included a special charge of $25 million for the company's share of
the cumulative  effect from Caltex's adoption of a new accounting  standard,  in
addition  to the third  quarter  special  charge  discussed  above.  Net  income
included  foreign  currency  gains of $1  million  in the  third  quarter  1999,
compared  with  losses  of $26  million  in the 1998  quarter.  1999  nine-month
earnings included foreign currency losses of $15 million, compared with gains of
$2 million in the 1998 nine months.

Refined  products trade sales volumes were 892,000  barrels per day in the third
quarter 1999, up 13 percent from the comparable  quarter last year. Year to date
sales  volumes  were up about 12  percent to 902,000  barrels  per day.  In both
periods, the increased volumes occurred primarily in Caltex's operations.

Net Income from Caltex operations contains the effects from special items, other
non-recurring  items, and foreign currency gains and losses. The following table
identifies the effects of these items:

As indicated by the table  above,adjusted  net income from Caltex operations has
declined in both 1999 periods,  despite  increased sales volumes  primarily from
trading of crude oil and refined  products.  This was primarily due to depressed
refined  products  refining and sales  margins in the  Asia-Pacific  region.  In
particular,  results from Caltex's Korean operations suffered from lower refined
products  sales  margins in the third  quarter  and first  nine  months of 1999,
compared  with the  corresponding  year-ago  periods.  The  Asia-Pacific  market
continues to experience  competitive price discounting and has failed to recover
rising crude oil costs in the prices for refined products.

In addition to the decline in adjusted  Caltex  earnings in both  periods  shown
above,  earnings from the company's  international  shipping operations were $12
million  lower in the third  quarter  1999 and $25  million  lower for 1999 nine
months, compared with the corresponding periods last year.

Chemicals  net income was $31 million in the 1999 third  quarter,  compared with
$14 million in last year's third  quarter.  Net income for the first nine months
of 1999 was $41  million  compared  with $124  million  in 1998.  There  were no
special  items for the 1999  third  quarter,  but  year-to-date  charges  of $43
million for asset write-offs,  $28 million for environmental remediation and $20
million for restructuring  charges reduced nine-month net income by $91 million.
Net income for the third quarter and nine months of 1998 included  charges of $5
million for environmental remediation provisions. Excluding special items in all
periods, third quarter 1999 chemicals net income was $31 million,  compared with
$19 million in the 1998 quarter and $132 million  compared with $129 million for
the first nine months of 1999 and 1998,  respectively.  The increase in earnings
excluding  special  charges for the third quarter was the result of improvements
in margins for the company's major chemical  products,  primarily  polyethylene,
where higher selling prices  improved  margins despite a slight decline in sales
volume. Additionally, operating expenses fell between periods.

All Other activities include coal operations,  interest expense, interest income
on cash and  marketable  securities,  real estate and insurance  activities  and
corporate center costs. These activities  incurred net charges of $80 million in
the third quarter of 1999, compared with income of $42 million in the comparable
prior-year  quarter.  The third quarter of 1999 included a special charge for an
adjustment  to the  carrying  value of the  company's  coal  assets,  which  are
currently  under  negotiation  for  sale.  In  the  1998  quarter,  the  company
recognized  special  gains of $105  million  reflecting  proceeds  from  several
settlements with various insurers related to environmental cost recovery claims.

Year-to-date  charges were $232 million in 1999, compared with net income of $19
million in last year's first nine months.  Special items  included in nine month
1999  results  included  an asset  sale gain of $60  million  and  restructuring
charges of $29 million,  in addition to the third quarter write-down of the coal
assets.  Special items of $174 million in the first nine months of 1998 included
favorable  prior-year  income tax related  adjustments of $137 million and asset
write-offs of $68 million in addition to the third quarter special gains.

Excluding special items,  ongoing charges from activities other than coal in the
third  quarter of 1999 were $53 million  compared  with $82  million  last year.
Income tax benefits and gains associated with pension plan activity in 1999 were
partially  offset by higher net interest  expense.  Charges for nine months were
$258 million  compared with $191 million last year.  Higher  charges in the 1999
nine months were primarily the result of higher interest  expense on higher debt
levels in 1999. The net costs in 1998 included  recoveries of certain prior-year
claims and lower costs of variable  components of employee  compensation  plans.
Third quarter coal earnings,  excluding  special items, were $7 million compared
with $19 million in the 1998 quarter.  Year-to-date earnings,  excluding special
items, were $29 million compared with $37 million in 1998.

Liquidity and Capital Resources
- -------------------------------
Cash and cash  equivalents  totaled $703 million at September  30, 1999 - a $134
million  increase  from  year-end  1998.  In addition  to cash from  operations,
increases in long- and short-term debt funded the company's capital expenditures
and dividend payments to shareholders.

On October  27,  1999,  Chevron  declared a  quarterly  dividend of 65 cents per
share, an increase of 4 cents a share from the preceding quarter.

In March 1999,  Chevron  purchased  the  Rutherford-Moran  Oil  Corporation  and
another interest in Block 8/32, offshore Thailand, for approximately 1.1 million
shares  of its  treasury  stock,  $57  million  in cash  and the  assumption



                                      -25-
<PAGE>

of outstanding debt of $341 million.  Concurrent with the purchase, $202 million
of that debt was retired and the  remaining  $139 million was called and retired
in April 1999.  The company  financed these  retirements  through an increase in
short-term debt.

In September 1999, the company completed the acquisition of Petrolera  Argentina
San Jorge, a  privately-held  oil and gas exploration and production  company in
Argentina.  This  acquisition  was financed  with a  combination  of cash and an
increase in short-term debt.

The  company's  debt and capital lease  obligations  totaled  $8.317  billion at
September  30,  1999,  up $759  million or 10  percent  from  $7.558  billion at
year-end 1998.  Newly issued  long-term debt and capital lease  obligations  for
nine months 1999 totaled $728  million.  This increase was primarily due to $620
million  of  long-term  debt  issued  in July by the  company's  Employee  Stock
Ownership  Plan  (ESOP) at an average  rate of 7.42% and  guaranteed  by Chevron
Corporation.  The  proceeds  from the  issuance  of debt  were  paid to  Chevron
Corporation  in exchange for  Chevron's  assumption  of the existing  ESOP 8.11%
long-term  debt of $620  million.  Chevron  used the  cash  proceeds  to  reduce
existing short-term debt, primarily commercial paper. The additions to long-term
debt  were  partially  offset  by  scheduled  and  unscheduled   long-term  debt
repayments of $81 million and a scheduled non-cash retirement in January of ESOP
debt of $70 million.  These changes in long-term debt exclude the assumption and
retirement of long-term debt included in the Rutherford-Moran transaction. There
was a net increase of $182 million in  short-term  debt  (excluding  the current
portion of long-term  debt due for  repayment  in 12 months or less),  primarily
commercial  paper and  short-term  debt assumed in  acquisitions,  from year-end
1998.

Although the company  benefits from lower interest rates on short-term debt, its
proportionately  large amount of  short-term  debt has kept its ratio of current
assets to current  liabilities at relatively  low levels.  This ratio was .75 at
September  30,  1999,  down from .88 at year-end  1998.  A major  factor in this
reduction is an increase in current liabilities of $2.675 billion. This increase
was primarily due to the June 1999  reclassification  from noncurrent to current
of an  accrual of about $1 billion  established  in 1998 for the Cities  Service
litigation, an increase of $620 million in third-party accounts payable balances
in line with the 1999 increases in crude oil and refined  products  prices,  the
increase in short-term  debt and an increase in the current portion of long-term
debt.  Interest  will  continue  to accrue on the amount of the  judgment in the
Cities  Service  case until the matter is  resolved.  The company  continues  to
pursue the Cities Service matter in the courts.

The company's short-term debt,  consisting primarily of commercial paper and the
current portion of long-term debt, totaled $6.185 billion at September 30, 1999.
This amount includes $2.725 billion with termination  dates beyond one year that
was reclassified as long-term since the company has both the intent and ability,
as  evidenced  by revolving  credit  agreements,  to refinance it on a long-term
basis. The company's  practice has been to continually  refinance its commercial
paper, maintaining levels it believes to be economically attractive.

At October 31, 1999,  Chevron had $3.750 billion in committed credit  facilities
with various major banks,  $2.725 billion of which had termination  dates beyond
one year.

The company's debt ratio (total debt : total debt plus stockholders' equity) was
32 percent at  September  30,  1999,  about the same as at  year-end  1998.  The
company  continually  monitors its spending level, market conditions and related
interest rates to maintain what it believes to be reasonable debt levels to fund
its operating and capital expenditure activities.

In October,  the company issued $500 million of new 6.625%  long-term  debt. The
newly  issued debt will mature in 2004.  The cash  proceeds  from the debt issue
were used to reduce existing short-term debt,  primarily  commercial paper. This
debt issue reduced the company's existing "shelf" registrations on file with the
Securities and Exchange Commission to $800 million from $1.3 billion at December
31, 1998.

In December 1997,  Chevron's Board of Directors approved the repurchase of up to
$2 billion of its outstanding  common stock for use in its employee stock option
programs.  To date,  the company has purchased  6.4 million  shares at a cost of
about $484  million  under the  repurchase  program.  There has been no activity
under that program in 1999.

Worldwide  capital  and  exploratory  expenditures  for the first nine months of
1999, including the company's share of affiliates' expenditures,  totaled $4.781
billion,  up 25 percent  from $3.815  billion  spent in the first nine months of


                                      -26-
<PAGE>

1998.  Expenditures for international  exploration and production  activities in
the 1999 period were $3.024  billion or about 63 percent of total  expenditures,
reflecting the company's continued emphasis on increasing  international oil and
gas production.  1999 expenditures  include two significant  acquisitions in the
international  exploration  and  production  segment - Petrolera  Argentina  San
Jorge,  acquired  in the  third  quarter  1999,  and  the  Rutherford-Moran  Oil
Corporation, acquired in the first quarter 1999. The company's other segments in
the aggregate have incurred lower  expenditures in 1999,  compared with 1998, as
the  company  restricts  spending  in  these  areas  to fund  its  international
exploration  and  production  prospects.  Spending  outside  the  United  States
accounted  for 70 percent of total  expenditures  in nine months 1999,  compared
with 50  percent  in 1998.  The C&E  expenditures  for the full year 1999 in the
international  exploration and production  segment will be dependent upon, among
other factors, the ability of our partners, some of which are national petroleum
companies, to fund their share of project expenditures.
