APACHE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

These financial statements have been prepared by Apache Corporation (Apache or the Company) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC), and reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods, on a basis consistent with the annual audited financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies, and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These financial statements should be read in conjunction with the financial statements and the summary of significant accounting policies and notes thereto included in the Company's most recent annual report on Form 10-K.

Change in Accounting Principle - In December 2000, the staff of the SEC announced that commodity inventories should be carried at cost, not market value, despite longstanding industry practice. As a result, Apache changed its accounting for crude oil inventories in the fourth quarter of 2000, retroactive to the beginning of the year, and recognized a non-cash cumulative-effect charge to earnings effective January 1, 2000. Quarterly results for 2000 have been restated to reflect this change in accounting.

1. ACQUISITIONS AND DIVESTITURES

Acquisitions - In June 2000, Apache completed the acquisition of long-lived producing properties in the Permian Basin and South Texas from Collins & Ware, Inc. (Collins & Ware) for $320.7 million. The acquisition included estimated proved reserves of 83.7 million barrels of oil equivalent (MMboe) as of the acquisition date. One-third of the reserves are liquid hydrocarbons.

In August 2000, Apache completed the acquisition of a Delaware limited liability company (LLC) owned by subsidiaries of Occidental Petroleum Corporation (Occidental) and the related natural gas production for $321.2 million, plus future payments of approximately $44.0 million over four years. The Occidental properties are located in 32 fields on 93 blocks on the Outer Continental Shelf of the Gulf of Mexico. The acquisition included estimated proved reserves of 53.1 MMboe as of the acquisition date.

In December 2000, Apache completed the acquisition of Canadian properties from Canadian affiliates of Phillips Petroleum Company (Phillips) for $490.3 million. The acquisition included estimated proved reserves of approximately
70.0 MMboe as of the acquisition date. The properties comprise approximately 212,000 net developed acres and 275,000 net undeveloped acres, 786 square miles of 3-D seismic and 4,155 miles of 2-D seismic located in the Zama area of Northwest Alberta. The assets also include three sour gas plants with a total capacity of 150 million cubic feet (MMcf) per day, 13 compressor stations and 150 miles of owned and operated gas gathering lines.

On March 22, 2001, Apache completed the acquisition of substantially all of Repsol YPF's (Repsol) oil and gas concession interests in Egypt for approximately $446.9 million in cash, subject to normal post closing adjustments. The properties include interests in seven Western Desert concessions and have estimated proved reserves of 66 MMboe as of the acquisition date. The Company already holds interests in five of the seven concessions.

On March 27, 2001, Apache completed the acquisition of subsidiaries of Fletcher Challenge Energy (Fletcher) for approximately $465.0 million in cash and 1.64 million restricted shares of Apache common stock issued to Shell Overseas Holdings (valued at $61.04 per share), subject to normal post closing adjustments. The transaction included properties located in Canada's Western Sedimentary Basin and in Argentina and estimated proved reserves of 120.8 MMboe as of the acquisition date. Apache assumed a liability of $103.5 million representing the fair value of derivative instruments and fixed-price commodity contracts entered into by Fletcher.

On August 23, 2001, Apache completed the acquisition of properties located in Texas, Oklahoma and New Mexico with estimated proved reserves of 9.2 MMboe as of the acquisition date for approximately $42.5 million in cash and the assumption of certain liabilities, representing the fair value of derivative instruments of $9.2 million, subject to normal post closing adjustments.

Divestitures - During the nine months ended September 30, 2001, Apache sold
66.4 MMboe of proved reserves from largely marginal United States and Canadian properties, collecting cash of $233.3 million.

2. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Apache periodically enters into commodity derivatives contracts to manage its exposure to oil and gas price volatility. Commodity derivatives contracts, which are usually placed with major financial institutions that the Company believes are minimal credit risks, may take the form of futures contracts, swaps or options. The oil and gas reference prices upon which these commodity derivatives contracts are based, reflect various market indices that have a high degree of historical correlation with actual prices received by the Company. Realized gains and losses from the Company's price risk management activities are recognized in oil and gas production revenues when the associated production occurs and the resulting cash flows are reported as cash flows from operating activities.

Effective January 1, 2001, Apache adopted Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities". SFAS No. 133 establishes accounting and reporting standards requiring that all derivative instruments (including derivative instruments embedded in other contracts), as defined, be recorded in the balance sheet as either an asset or liability measured at fair value and

7

requires that changes in fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Hedge accounting treatment allows unrealized gains and losses to be deferred in other comprehensive income (for the effective portion of the hedge) until such time as the forecasted transaction occurs, and requires that a company formally document, designate, and assess the effectiveness of derivative instruments that receive hedge accounting treatment. Upon adoption, Apache formally documented and designated all hedging relationships and verified that its hedging instruments are effective in offsetting changes in actual prices received by the Company. Such effectiveness is monitored at least quarterly and any ineffectiveness is reported in other revenues (losses) in the statement of consolidated operations.

Apache's derivative positions break down into three general categories:
advances from gas purchasers, Apache hedging activity and derivatives inherited as part of the Fletcher and August 23, 2001 acquisitions. The carrying values at transition and September 30, 2001 are summarized below:

On the transition date, January 1, 2001, Apache recognized a derivative asset of $121.5 million reflecting the fair value of gas price swaps entered into in connection with certain advance payments received from gas purchasers in 1998 and 1997. Apache also recognized a derivative liability of $121.5 million as an embedded derivative in the contracts under which the advance payments were received. The liability reflects the obligation to deliver gas at market prices in excess of the contractual prices determined at the inception of these transactions.

The balance of Apache's derivative instruments relate to cash flow hedges on forecasted oil and gas sales, primarily entered into as the result of Apache's acquisition hedging strategy. On the transition date, the fair value of these derivative instruments represented a net liability of $116.2 million. The time value of zero-cost collars at September 30, 2001 was $23.9 million.

In connection with the Fletcher acquisition, Apache assumed liabilities for derivative instruments (fixed-price swaps and put options) and fixed-price physical contracts entered into by Fletcher. The $103.5 million fair value on the closing date was recorded as a cost of the Fletcher acquisition (see Note 1).

In connection with the acquisition completed August 23, 2001, Apache assumed liabilities for derivative instruments (fixed-price swaps and put options) with a fair value of $9.2 million on the closing date, which was recorded as a cost of the acquisition (see Note 1).

In early November 2001, due to credit issues surrounding the derivative market, Apache began to close out substantially all of its hedging positions. The Company does not expect to recognize a material gain or loss from the expected proceeds received in connection with termination of these positions.

4. DEBT

The Company's 9.25 percent notes due June 2002 are classified as long-term debt in the accompanying consolidated balance sheet as the Company has the ability and intent to refinance such amount on a long-term basis through either the issuance of commercial paper or borrowing under the U.S. portion of the global credit facility and the 364-day revolving credit facility.

5. STOCK DIVIDEND

On September 13, 2001, the Company's Board of Directors declared a 10 percent stock dividend payable on January 21, 2002 to shareholders of record on December 31, 2001. No fractional shares will be issued and payments will be made in lieu of fractional shares. In connection with the dividend, a reclassification was made to transfer $545 million from retained earnings to additional paid-in-capital in the accompanying consolidated balance sheet as of September 30, 2001. The following pro forma information shows the effect on the Company's consolidated results of operations as if the stock dividend were made on January 1, 2000.

6. MINORITY INTEREST

In August 2001, Apache entered into a series of financing transactions, described below, to raise a total of $440.7 million for investments, to pay down existing debt and increase financial flexibility.

Apache contributed interests in various fields valued at $923 million to new subsidiaries in connection with the financing transactions. Additionally, on August 7, 2001, Apache purchased $116.7 million in U.S. Government Agency Notes, maturing in October 2002, which were contributed to the subsidiaries. Unrelated institutional investors contributed $443 million ($440.7 million, net of issuance costs) to the various subsidiaries in exchange for preferred stock of the subsidiaries and a limited partner interest in one of the entities. The third party investors are entitled to receive a weighted average return of 123 basis points above the prevailing LIBOR interest rate. The preferred and limited partner interests are repayable from the assets of the subsidiaries with limited recourse to Apache.

The assets, liabilities and operations of the subsidiaries are included in Apache's consolidated financial statements at historical costs, with the preferred and limited partner interests of the subsidiaries reflected as a minority interest. The U.S. Government Agency Notes are accounted for as "held-to-maturity" securities shown as long-term investments in the accompanying balance sheet.

7. RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 142, "Goodwill and Other Intangible Assets." SFAS No. 142 establishes accounting and reporting standards discontinuing goodwill amortization and requiring a periodic review for impairments. Apache's goodwill represents the excess of the purchase price over the estimated fair value of the assets acquired and liabilities assumed in the Fletcher and Repsol acquisitions (see Note 1). The goodwill currently is being amortized on a straight-line basis over 20 years. Apache will continue to record amortization of approximately $2.5 million per quarter through December 31, 2001. The

10

Company will adopt SFAS No. 142 on January 1, 2002. No impairment of goodwill is currently anticipated; however, the Company will continue to assess recoverability of goodwill on an ongoing basis.

In June 2001, the FASB issued SFAS No. 143 "Accounting for Asset Retirement Obligations." The statement requires entities to record the fair value of legal obligations associated with the retirement of tangible long-lived assets in the period in which it is incurred. When the liability is initially recorded, the entity increases the carrying amount of the related long-lived asset. Over time, accretion of the liability is recognized each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. SFAS No. 143 is effective for fiscal years beginning after June 15, 2002, with earlier adoption encouraged. The Company is currently assessing the impact of adopting SFAS No. 143 on its financial condition and results of operations and has not determined the timing of adoption.

8. SUPPLEMENTAL CASH FLOW INFORMATION

NON-CASH INVESTING AND FINANCING ACTIVITIES

In January 2000, the Company acquired producing properties formerly owned by a subsidiary of Repsol for cash, plus assumed liabilities of $29.8 million.

In March 2001, the Company acquired substantially all of Repsol's oil and gas concession interests in Egypt for cash and the assumption of certain non-cash liabilities. The accompanying financial statements include the non-cash amounts detailed in Note 1.

In March 2001, the Company acquired subsidiaries of Fletcher for cash, 1.64 million restricted shares of common stock and the assumption of certain non-cash liabilities. The accompanying financial statements include the non-cash amounts detailed in Note 1.

In August 2001, the Company acquired properties located in Texas, Oklahoma and New Mexico for cash and the assumption of certain non-cash liabilities. The accompanying financial statements include the non-cash amounts detailed in Note 1.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

Record natural gas production and strong oil production both contributed to solid third quarter and nine-month results, mitigating the impact of declining commodity prices. On a barrel-of-oil-equivalent (Boe) basis, third quarter daily production increased 89,483 barrels of oil equivalent per day (Boe/d) to a record 359,979 Boe/d, 33 percent higher than the third quarter of last year. Following are the 2001 third quarter and nine-month highlights:

o Natural gas production rose to a record 1.2 billion cubic feet per day (Bcf/d) in the third quarter, slightly exceeding the record setting second quarter of 2001 and 35 percent above the prior-year period. Third quarter oil production increased 37,496 barrels of oil per day (Bbl/d) to 153,369 Bbl/d, 32 percent above the year-ago period. For the nine-month period, production rates of 1.1 Bcf/d and 143,311 Bbl/d were 40 percent and 25 percent ahead of 2000, respectively.

o Year-to-date income attributable to common stock of $630.1 million ($5.05 per basic common share) exceeded the prior year by $189.2 million, or 43 percent, while third quarter earnings of $151.9 million declined 23 percent from the comparable period. Record production mitigated the impact of a $.90 per thousand cubic feet (Mcf) decline in gas price realizations and a $4.96 per barrel decline in oil prices from third quarter 2000.

o Net cash provided by operating activities increased $588.4 million, or 61 percent, to $1.5 billion from the $1.0 billion generated during the first nine months of 2000.

Commodity Prices - Apache's third quarter realized oil price declined $4.96 to $24.15 per barrel from $29.11 in the third quarter of 2000, decreasing revenues by $52.9 million. Third quarter natural gas price realizations declined $.90 to $2.80 per Mcf from $3.70 per Mcf in the year-ago period, negatively impacting revenues by $72.6 million. For the nine-month period oil price realizations decreased $1.85 to $25.01 per barrel from $26.86 in 2000, decreasing revenues by $58 million. Year-to-date natural gas price realizations of $4.05 per Mcf exceeded the prior year by $.92, positively impacting revenues by $201.2 million.

Production - Oil production increased 25 percent during the first nine months of 2001 when compared to the same period last year, which positively impacted revenues by $195.2 million. The improvement was primarily the result of production from acquisitions completed since the first half of 2000, completion of the Gipsy/North Gipsy development in Australia and first production from the Legendre field in Australia. Gas production increased 40 percent during the first nine months of 2001 compared to the same period last year, positively impacting revenues by $350.3 million. The increase was primarily attributable to production from the acquisitions mentioned above and strong results from the Ladyfern area in Canada.

RESULTS OF OPERATIONS

Apache reported 2001 third quarter income attributable to common stock of $151.9 million compared to income of $197.3 million in the prior year. Basic net income per common share of $1.22 for the third quarter of 2001, decreased 26 percent from the $1.64 reported in 2000. The variance to the prior-year quarter was attributable to lower commodity prices, which offset higher volumes, and higher DD&A expense and lease operating costs.

For the first nine months of 2001, income attributable to common stock of $630.1 million, or $5.05 per basic common share, compared to $440.9 million, or $3.80 per share, in the comparable year-earlier period. The increase resulted primarily from increased oil and gas production revenues partially offset by higher DD&A expense, lease operating costs, severance and other taxes and impairments of unproved property costs in Poland and China.

For the third quarter of 2001, total revenues increased five percent to $652.4 million compared to $618.5 million in 2000. The increase was the result of a 35 percent increase in natural gas production, a 32 percent increase in oil production, partially offset by a 24 percent decrease in the average realized price for natural gas and a 17 percent decrease in the average realized price for oil. Crude oil, including natural gas liquids, contributed 54 percent and natural gas contributed 46 percent of oil and gas production revenues during the third quarter of 2001.

13

For the first nine months of 2001, total revenues increased 45 percent to $2.2 billion compared to $1.6 billion for the same period in 2000. Revenues from oil and gas production increased 45 percent over the same period in 2000, with crude oil, including natural gas liquids, contributing 45 percent and natural gas contributing 55 percent of oil and gas production revenues. The increase in oil and gas production revenues was the result of a 40 percent increase in gas production, a 29 percent increase in the average realized gas price and a 25 percent increase in oil production.

Volume and price information for the Company's oil and gas production is summarized in the following table:

THIRD QUARTER 2001 REVENUES COMPARED TO 2000

Natural gas sales for the third quarter of 2001 totaled $305.6 million, slightly more than the third quarter of 2000. Average realized natural gas prices decreased 24 percent, negatively impacting revenues by $72.6 million. The net result of derivative instruments increased the Company's realized gas price by $.18 per Mcf during the third quarter of 2001 and $.06 per Mcf for the same period in 2000.

Natural gas production increased 309.8 million cubic feet per day (MMcf/d), or 35 percent, on a worldwide basis, favorably impacting revenues by $79.7 million. Production from properties acquired from Phillips in December 2000 and Fletcher in March 2001, and strong results from the Ladyfern area were the primary contributors to the 207.6 MMcf/d, or 154 percent, gas production increase in Canada. The U.S. increased 47 MMcf/d primarily the result of production from properties acquired from Occidental in August 2000. Egypt increased 54.6 MMcf/d, or 110 percent, due to production from properties acquired from Repsol in March 2001.

The Company's crude oil sales for the third quarter of 2001 totaled $340.7 million, a 10 percent increase from the third quarter of 2000, due to increased production volumes. Average realized oil prices decreased $4.96 per barrel, negatively impacting revenues by $52.9 million. Realized losses from hedging positions negatively impacted the Company's realized oil price by $.47 per barrel during the third quarter of 2001 and $1.88 per barrel in the third quarter of 2000.

Oil production increased 32 percent compared to the prior year, favorably impacting revenues by $83.3 million. Canada increased 10,460 Bbl/d and Egypt increased 17,717 Bbl/d, primarily due to production from properties acquired from Phillips, Fletcher and Repsol, as mentioned above. Completion of the Gipsy/North Gipsy development and first production from the Legendre field were the primary contributors to the 10,308 Bbl/d increase in Australia.

Revenue from the sale of natural gas liquids totaled $12.6 million for the third quarter of 2001, compared to $14.8 million for the third quarter of 2000 in response to an 18 percent drop in realized prices.

YEAR-TO-DATE 2001 REVENUES COMPARED TO 2000

Natural gas sales for the first nine months of 2001 of $1.2 billion increased $551.5 million, or 81 percent, from the same period of 2000. Average realized natural gas prices increased 29 percent, positively affecting revenues by $201.2 million. U.S. natural gas production, which comprised 56 percent of the Company's worldwide gas production, sold at an average price of $4.61 per Mcf, 33 percent higher than in 2000, positively impacting natural gas revenues by $161.9 million. The net result of derivative instruments increased the Company's realized gas price by a $.04 per Mcf during the first nine months of 2001 and 2000.

Production from properties acquired from Phillips and Fletcher and strong results from the Ladyfern area were the primary contributors to the 154 MMcf/d gas production increase in Canada. The U.S. increased 108.7 MMcf/d due to the production from properties acquired from Collins & Ware and Occidental, and Egypt increased 43.7 MMcf/d due to producing properties acquired from Repsol.

For the first nine months of 2001, oil revenues of $978.3 million, increased $137.2 million, or 16 percent, from the same period in 2000 due to higher production. On a worldwide basis, average oil prices decreased $1.85 per barrel, or seven percent, to $25.01 per barrel negatively impacting oil revenues by $58 million. Realized losses from hedging positions negatively impacted the Company's realized oil price by $.57 per barrel during the first nine months of 2001 and $1.83 per barrel during the first nine months of 2000.

Oil production increased 11,337 Bbl/d in Canada, 2,968 Bbl/d in the U.S. and 8,689 Bbl/d in Egypt, primarily driven by production from properties acquired from Phillips, Fletcher, Repsol, Collins & Ware and Occidental as mentioned above. Completion of the Gipsy/North Gipsy development and first production from the Legendre field were the primary contributors to the 6,016 Bbl/d increase in Australia.

Natural gas liquids revenues for the first nine months of 2001 of $44.2 million increased $10.1 million, or 30 percent, from the same period in 2000. Natural gas liquids prices increased by $.35 per barrel, or two percent, and natural gas liquids production increased 1,891 barrels per day, or 28 percent.

EXPENSES

The Company's DD&A expense for the third quarter and first nine months of 2001 increased $63.1 million and $175.8 million, respectively, over the comparable periods of 2000. Full cost DD&A expense increased $.23 per Boe, from $5.82 per Boe in the third quarter of 2000 to $6.05 per Boe in 2001. For the nine months ended September 30, 2001, the full cost DD&A rate increased $.31 per Boe, from $5.70 per Boe to $6.01 per Boe. For the first nine months of 2001, the full cost DD&A rate for the U.S. increased $.44 per Boe from $6.13 per Boe to $6.57 per Boe, primarily the result of the acquisition of the Occidental properties in August 2000 and rising U.S. drilling and finding costs. The acquisition of the Phillips properties in December 2000 carry higher DD&A costs, which helped push the full cost DD&A rate in Canada from $5.55 per Boe to $5.87 per Boe.

During the second quarter of 2001, the Company recorded a nonrecurring $65 million impairment ($41 million after-tax) of unproved property costs in Poland and China.

Lease operating expense (LOE) for the third quarter and first nine months of 2001 increased $36.8 million and $108.4 million, respectively, over the comparable periods of 2000. On an equivalent barrel basis, LOE increased $.45 per Boe to $3.12 per Boe in the third quarter and $.52 per Boe to $3.20 per Boe in the first nine months of 2001 compared to the same periods in the prior year. The higher costs were partially attributable to the acquisition of Canadian and offshore oil properties, which carried a higher LOE per Boe rate than the Company's base production. Increased workover activities in the U.S. and Canada and rising fuel cost for electric power also contributed to the increase. The workovers accelerated production, allowing Apache to maximize the benefits of high oil and gas prices. Severance and other taxes increased $.6 million in the third quarter and $22.1 million in the first nine months of 2001 primarily due to the impact of higher oil and gas prices on severance taxes, which generally are based on a percentage of oil and gas production revenues. Also contributing to the increase were higher effective production tax rates due to a loss of incentives in Oklahoma and an increase in Canadian Large Corporation Tax due to the added production from the Fletcher acquisition properties.

G&A expense in the third quarter and first nine months of 2001 increased $4.7 million or 26 percent, and $17 million or 35 percent, respectively, from a year ago. The Company's overall infrastructure was enlarged to properly handle increased responsibilities associated with recent producing property acquisitions. On an equivalent barrel basis, G&A expenses decreased $.04, to $.69 per Boe, for the third quarter of 2001 as compared to $.73 per Boe for the same period in 2000.

Net financing costs for the third quarter remained flat, while first nine months of 2001 increased $8.9 million, or 11 percent, compared to a year ago. This increase is primarily due to higher gross interest expense, the result of a higher average outstanding debt balance related to acquisition activity in the second half of 2000 and the first quarter of 2001.

MARKET RISK

COMMODITY RISK

The Company's major market risk exposure continues to be the pricing applicable to its oil and gas production. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot prices applicable to its United States and Canadian natural gas production. Historically, prices received for oil and gas production have been volatile and unpredictable. Price volatility is expected to continue. See "Results of Operations" above.

In early November 2001, due to credit issues surrounding the derivative market, Apache began to close out substantially all of its hedging positions. The Company does not expect to recognize a material gain or loss from the expected proceeds received in connection with termination of these positions.

INTEREST RATE RISK

The Company considers its interest rate risk exposure to be minimal as a result of fixed interest rates on approximately 67 percent of the Company's debt. At September 30, 2001, total debt included $768 million of floating-rate debt. As a result, Apache's annual interest cost in 2001 will fluctuate based on short-term interest rates

16

on approximately 33 percent of it total debt outstanding at September 30, 2001. The Company did not have any open derivative contracts relating to interest rates at September 30, 2001.

Minority Interest - At September 30, 2001, the Company's minority interest included $443 million in contributions by unrelated institutional investors. The third party investors are entitled to receive a weighted average return of 123 basis points above the prevailing LIBOR interest rate. As a result, Apache's annual minority interest cost will fluctuate based on short-term LIBOR interest rates.

CASH FLOW, LIQUIDITY AND CAPITAL RESOURCES

CAPITAL COMMITMENTS

Apache's primary cash needs are for exploration, development and acquisition of oil and gas properties, repayment of principal and interest on outstanding debt, payment of dividends and capital obligations for affiliated ventures. The Company may also elect to use cash flow to pay down debt. Apache budgets capital expenditures based upon projected cash flow and routinely adjusts its capital expenditures in response to changes in oil and natural gas prices and corresponding changes in cash flow. The Company cannot accurately predict future oil and gas prices.

Capital Expenditures - A summary of oil and gas capital expenditures during the first nine months of 2001 and 2000 is presented below:

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

On March 22, 2001, Apache completed the acquisition of substantially all of Repsol's oil and gas concession interests in Egypt for approximately $446.9 million in cash, subject to normal post-closing adjustments. The properties include interests in seven Western Desert concessions and have estimated proved reserves of 66 MMboe as of the acquisition date. The Company already holds interests in five of the seven concessions. The transaction was funded through the issuance of commercial paper.

On March 27, 2001, Apache completed the acquisition of subsidiaries of Fletcher for approximately $465.0 million in cash and 1.64 million restricted shares of Apache common stock (valued at $61.04 per share), subject to normal post closing adjustments. The transaction included properties located in Canada's Western Sedimentary Basin and in Argentina and have estimated proved reserves of 120.8 MMboe as of the acquisition date. Apache assumed a liability of $103.5 million representing the fair value of derivative instruments and fixed-price commodity contracts entered into by Fletcher. The cash portion of the acquisition was funded through the issuance of commercial paper, as well as advances under the Canadian portion of the global credit facility.

CAPITAL RESOURCES AND LIQUIDITY

Net Cash Provided by Operating Activities - Apache's net cash provided by operating activities during the first nine months of 2001 totaled $1.5 billion, an increase of 61 percent from $961.1 million in the first nine months of

17

2000. This increase was primarily due to higher oil and gas revenues generated from properties acquired since the first half of 2000 and higher realized gas prices as compared to last year.

Liquidity - The Company had $67.9 million in cash and cash equivalents on hand at September 30, 2001, up from $37.2 million at December 31, 2000. Apache's ratio of current assets to current liabilities was 1.14 at September 30, 2001 and December 31, 2000.

Apache believes that cash on hand, net cash generated from operations, and unused committed borrowing capacity under its global credit facility will be adequate to satisfy the Company's financial obligations to meet future liquidity needs for the foreseeable future. As of September 30, 2001, Apache's available borrowing capacity under its global credit facility and 364-day credit facility was $771 million.

FUTURE TRENDS

Apache's strategy is to increase its oil and gas reserves, production, cash flow and earnings through a balanced growth program that involves:

o Exploiting our existing asset base through workovers and development wells to increase productive capacity.

o Drilling exploration wells to add new reserves.

o Acquiring properties to which we can add value.

EXPLOITING OUR EXISTING ASSET BASE THROUGH WORKOVERS AND DEVELOPMENT WELLS TO INCREASE PRODUCTIVE CAPACITY

Apache seeks to maximize the value of our existing asset base by conducting workovers and development drilling within known limits of previously recognized reservoirs to increase productive capacity and/or the efficiency or rate of existing fields.

DRILLING EXPLORATION WELLS TO ADD NEW RESERVES

Apache seeks to add new reserves through drilling exploratory wells in all our regions. Higher risk, higher reward exploration is conducted in Canada and select international core areas. Our international investments and exploration activities are a significant component of our long-term growth strategy. They complement our United States operations, which are more development oriented.

ACQUIRING PROPERTIES TO WHICH WE CAN ADD VALUE

Apache seeks to purchase reserves at reasonable prices by generally avoiding auction processes where we are competing against other buyers. Our aim is to follow each acquisition with a cycle of reserve enhancement, property consolidation and cash flow acceleration, facilitating asset growth and debt reduction.

A critical component in implementing our three-pronged growth strategy is maintenance of significant financial flexibility. We are committed to preserving a strong balance sheet and credit position that gives us the foundation required to pursue our growth initiatives.

FORWARD-LOOKING STATEMENTS AND RISK

Certain statements in this report, including statements of the future plans, objectives, and expected performance of the Company, are forward-looking statements that are dependent upon certain events, risks and uncertainties that may be outside the Company's control, and which could cause actual results to differ materially from those anticipated. Some of these include, but are not limited to, the market prices of oil and gas, economic and competitive conditions, inflation rates, legislative and regulatory changes, financial market conditions, political and economic uncertainties of foreign governments, future business decisions, and other uncertainties, all of which are difficult to predict.

There are numerous uncertainties inherent in estimating quantities of proved oil and gas reserves and in projecting future rates of production and the timing of development expenditures. The total amount or timing of

18

actual future production may vary significantly from reserves and production estimates. The drilling of exploratory wells can involve significant risks, including those related to timing, success rates and cost overruns. Lease and rig availability, complex geology and other factors can affect these risks. Although Apache makes use of futures contracts, swaps, options and fixed-price physical contracts to mitigate risk, fluctuations in oil and gas prices, or a prolonged continuation of low prices, may substantially adversely affect the Company's financial position, results of operations and cash flows.

Shares of Stock which may be issued upon exercise of Options shall be applied to reduce the maximum number of shares of Stock remaining available for use under the Plan. The Company shall at all times during the term of the Plan and while any Options are outstanding retain as authorized and unissued Stock, or as treasury Stock, at least the number of shares from time to time required under the provisions of the Plan, or otherwise assure itself of its ability to perform its obligations hereunder.

4.2 Other Shares of Stock. Any shares of Stock that are subject to an Option which expires or for any reason is terminated unexercised, and any shares of Stock that for any other reason are not issued to an Eligible Employee or are forfeited shall automatically become available for use under the Plan.

4.3 Adjustments for Stock Split, Stock Dividend, etc. If the Company shall at any time increase or decrease the number of its outstanding shares of Stock or change in any way the rights and privileges of such shares by means of the payment of a Stock dividend or any other distribution upon such shares payable in Stock, or through a Stock split, subdivision, consolidation, combination, reclassification or recapitalization involving the Stock then in relation to the Stock that is affected by one or more of the above events, the numbers, rights and privileges of the following shall be, in each case, equitably and proportionally adjusted to take into account the occurrence of any of the above events, (i) the shares of Stock as to which Options may be granted under the Plan; (ii) the shares of Stock then included in each outstanding Option granted hereunder; and (iii) the Option Price for each outstanding Option granted hereunder.

4.4 Dividend Payable in Stock of Another Corporation, Etc. If the Company shall at any time pay or make any dividend or other distribution upon the Stock payable in securities or other property (except money or Stock), a proportionate part of such securities or other property shall be set aside and delivered to any

4

Participant then holding an Option for the particular type of Stock for which the dividend or other distribution was made, upon exercise thereof. Prior to the time that any such securities or other property are delivered to a Participant in accordance with the foregoing, the Company shall be the owner of such securities or other property and shall have the right to vote the securities, receive any dividends payable on such securities, and in all other respects shall be treated as the owner. If securities or other property which have been set aside by the Company in accordance with this Section are not delivered to a Participant because an Option is not exercised, then such securities or other property shall remain the property of the Company and shall be dealt with by the Company as it shall determine in its sole discretion.

4.5 Other Changes in Stock. In the event there shall be any change, other than as specified in Sections 4.3 and 4.4, in the number or kind of outstanding shares of Stock or of any stock or other securities into which the Stock shall be changed or for which it shall have been exchanged, and if the Committee shall in its discretion determine that such change equitably requires an adjustment in the number or kind of shares subject to outstanding Options or which have been reserved for issuance pursuant to the Plan but are not then subject to an Option, then such adjustments shall be made by the Committee and shall be effective for all purposes of the Plan and on each outstanding Option that involves the particular type of stock for which a change was effected.

4.6 Rights to Subscribe. If the Company shall at any time grant to the holders of its Stock rights to subscribe pro rata for additional shares thereof or for any other securities of the Company or of any other corporation, there shall be reserved with respect to the shares then under Option to any Participant of the particular class of Stock involved the Stock or other securities which the Participant would have been entitled to subscribe for if immediately prior to such grant the Participant had exercised his entire Option. If, upon exercise of any such Option, the Participant subscribes for the additional shares of other securities, the aggregate Option Price shall be increased by the amount of the price that is payable by the Participant for such Stock or other securities.

4.7 General Adjustment Rules. No adjustment or substitution provided for in this
Section 4 shall require the Company to sell a fractional share of Stock under any Option, or otherwise issue a fractional share of Stock, and the total substitution or adjustment with respect to each Option shall be limited by deleting any fractional share. In the case of any such substitution or adjustment, the aggregate Option Price for the shares of Stock then subject to the Option shall remain unchanged but the Option Price per share under each such Option shall be equitably adjusted by the Committee to reflect the greater or lesser number of shares of Stock or other securities into which the Stock subject to the Option may have been changed.

5

4.8 Determination by the Committee, Etc. Adjustments under this Section 4 shall be made by the Committee, whose determinations with regard thereto shall be final and binding upon all parties.

SECTION 5

REORGANIZATION OR LIQUIDATION

In the event that the Company is merged or consolidated with another corporation and the Company is not the surviving corporation, or if all or substantially all of the assets or more than 20 percent of the outstanding voting stock of the Company is acquired by any other corporation, business entity or person, or in case of a reorganization (other than a reorganization under the United States Bankruptcy Code) or liquidation of the Company, and if the provisions of Section 9 do not apply, the Committee, or the board of directors of any corporation assuming the obligations of the Company, shall, as to the Plan and outstanding Options either (i) make appropriate provision for the adoption and continuation of the Plan by the acquiring or successor corporation and for the protection of any such outstanding Options by the substitution on an equitable basis of appropriate stock of the Company or of the merged, consolidated or otherwise reorganized corporation which will be issuable with respect to the Stock, provided that no additional benefits shall be conferred upon the Participants holding such Options as a result of such substitution, and the excess of the aggregate Fair Market Value of the shares subject to the Options immediately after such substitution over the aggregate Option Price thereof is not more than the excess of the aggregate Fair Market Value of the shares subject to such Options immediately before such substitution over the aggregate Option Price thereof, or (ii) upon written notice to the Participants, provide that all unexercised Options must be exercised within a specified number of days of the date of such notice or they will be terminated. In the latter event, the Committee shall accelerate the vesting dates of outstanding Options so that all Options become fully vested and exercisable prior to any such event.

6

SECTION 6

PARTICIPATION

Participants in the Plan shall be those Eligible Employees who, in the judgment of the Committee, are performing, or during the term of their incentive arrangement will perform, vital services in the management, operation and development of the Company or an Affiliated Corporation, and significantly contribute, or are expected to significantly contribute, to the achievement of long-term corporate economic objectives. Participants may be granted from time to time one or more Options; provided, however, that the grant of each such Option shall be separately approved by the Committee, and receipt of one such Option shall not result in automatic receipt of any other Option. Upon determination by the Committee that an Option is to be granted to a Participant, written notice shall be given to such person, specifying the terms, conditions, rights and duties related thereto. Each Participant shall, if required by the Committee, enter into an agreement with the Company, in such form as the Committee shall determine and which is consistent with the provisions of the Plan, specifying such terms, conditions, rights and duties. Options shall be deemed to be granted as of the date specified in the grant resolution of the Committee, which date shall be the date of any related agreement with the Participant. In the event of any inconsistency between the provisions of the Plan and any such agreement entered into hereunder, the provisions of the Plan shall govern.

SECTION 7

STOCK OPTIONS

7.1 Grant of Stock Options. Coincident with or following designation for participation in the Plan, a Participant may be granted one or more Options. In no event shall the exercise of one Option affect the right to exercise any other Option or affect the number of shares of Stock for which any other Option may be exercised, except as provided in subsection 7.2(j).

7.2 Stock Option Agreements. Each Option granted under the Plan shall be evidenced by a written stock option agreement which shall be entered into by the Company and the Participant to whom the Option is granted (the "Option Holder"), and which shall contain the following terms and conditions, as well as such other terms and conditions, not inconsistent therewith, as the Committee may consider appropriate in each case.

(a) Number of Shares. Each stock option agreement shall state that it covers a specified number of shares of the Stock, as determined by the Committee.

7

(b) Price. The price at which each share of Stock covered by an Option may be purchased shall be determined in each case by the Committee and set forth in the stock option agreement, but in no event shall the price be less than the Fair Market Value of the Stock on the date the Option is granted.

(c) Duration of Options; Employment Required For Exercise. Each stock option agreement shall state the period of time, determined by the Committee, within which the Option may be exercised by the Option Holder (the "Option Period"). The Option Period must end, in all cases, not more than ten years from the date an Option is granted. Except as otherwise provided in Sections 5 and 8 and subsection 7.2(d)(iv) hereof, each Option granted under the Plan shall become exercisable in increments such that 25 percent of the Option will become exercisable on each of the four subsequent one-year anniversaries of the date the Option is granted, but each such additional 25 percent increment shall become exercisable only if the Option Holder has been continuously employed by the Company from the date the Option is granted through the date on which each such additional 25 percent increment becomes exercisable.

(d) Termination of Employment, Death, Disability, Etc. Each stock option agreement shall provide as follows with respect to the exercise of the Option upon termination of the employment or the death of the Option Holder:

(i) If the employment of the Option Holder is terminated within the Option Period for cause, as determined by the Company, the Option shall thereafter be void for all purposes. As used in this subsection 7.2(d), "cause" shall mean a gross violation, as determined by the Company, of the Company's established policies and procedures, provided that the effect of this subsection
7.2(d) (i) shall be limited to determining the consequences of a termination and that nothing in this subsection 7.2(d) (i) shall restrict or otherwise interfere with the Company's discretion with respect to the termination of any employee.

(ii) If the Option Holder retires from employment by the Company or its affiliates on or after attaining age 60, the Option may be exercised by the Option Holder within 36 months following his or her retirement (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Option Holder's death during such 36-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of the Option Holder's retirement.

(iii) If the Option Holder becomes disabled (as determined pursuant to the Company's Long-Term Disability Plan), during the Option Period while still employed, or within the three-month period referred to in (v) below, or within the

8

36-month period referred to in (ii) above, the Option may be exercised by the Option Holder or by his or her guardian or legal representative, within twelve months following the Option Holder's disability, or within the 36-month period referred to in (ii) if applicable and if longer (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Option Holder's death during such twelve-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of the Option Holder's disability.

(iv) In the event of the Option Holder's death while still employed by the Company, each Option of the deceased Option Holder may be exercised by those entitled to do so under the Option Holder's will or under the laws of descent and distribution within twelve months following the Option Holder's death (provided that in any event such exercise must occur within the Option Period), but not thereafter, as to all shares of Stock which are subject to such Option, including each 25 percent increment of the Option, if any, which has not yet become exercisable at the time of the Option Holder's death. In the event of the Option Holder's death within the 36-month period referred to in (ii) above or within the twelve-month period referred to in (iii) above, each Option of the deceased Option Holder that is exercisable at the time of death may be exercised by those entitled to do so under the Option Holder's will or under the laws of descent and distribution within twelve months following the Option Holder's death or within the 36-month period referred to in (ii), if applicable and if longer (provided that in any event such exercise must occur within the Option Period). The provisions of this paragraph (iv) of subsection 7.2(d) shall be applicable to each Stock Option Agreement as if set forth therein word for word. Each Stock Option Agreement executed by the Company prior to the adoption of this provision shall be deemed amended to include the provisions of this paragraph and all Options granted pursuant to such Stock Option Agreements shall be exercisable as provided herein.

(v) If the employment of the Option Holder by the Company is terminated (which for this purpose means that the Option Holder is no longer employed by the Company or by an Affiliated Corporation) within the Option Period for any reason other than cause, retirement on or after attaining age 60, disability or the Option Holder's death, the Option may be exercised by the Option Holder within three months following the date of such termination (provided that such exercise must occur within the Option Period), but not thereafter. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of termination of employment.

9

(e) Transferability. Each stock option agreement shall provide that the Option granted therein is not transferable by the Option Holder except by will or pursuant to the laws of descent and distribution, and that such Option is exercisable during the Option Holder's lifetime only by him or her, or in the event of disability or incapacity, by his or her guardian or legal representative.

(f) Agreement to Continue in Employment. Each stock option agreement shall contain the Option Holder's agreement to remain in the employment of the Company, at the pleasure of the Company, for a continuous period of at least one year after the date of such stock option agreement, at the salary rate in effect on the date of such agreement or at such changed rate as may be fixed, from time to time, by the Company.

(g) Exercise, Payments, Etc.

(i) Each stock option agreement shall provide that the method for exercising the Option granted therein shall be by delivery to the Office of the Secretary of the Company or to the Administrative Agent of written notice specifying the number of shares of Stock with respect to which such Option is exercised and payment to the Company of the aggregate Option Price. Such notice shall be in a form satisfactory to the Committee and shall specify the particular Option (or portion thereof) which is being exercised and the number of shares of Stock with respect to which the Option is being exercised. The exercise of the Option shall be deemed effective upon receipt of such notice by the Office of the Secretary or by the Administrative Agent and payment is made to the Company of the aggregate Option Price (the "Exercise Date"); however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) below, the Exercise Date shall be deemed to be the date of such sale. If requested by the Company, such notice shall contain the Participant's representation that he or she is purchasing the Stock for investment purposes only and his or her agreement not to sell any stock so purchased in any manner that is in violation of the Securities Act of 1933, as amended, or any applicable state law, and such restriction, or notice thereof, shall be placed on the certificates representing the Stock so purchased. The purchase of such Stock shall take place upon delivery of such notice to the Office of the Secretary of the Company or to the Administrative Agent, at which time the aggregate Option Price shall be paid in full to the Company by any of the methods or any combination of the methods set forth in 7.2(g)(iii) below.

(ii) Except as referenced below in connection with the Deferred Delivery Plan, the shares of Stock to which the Participant is entitled as a result of the exercise of the Option shall be issued by the Company and (A) delivered by electronic means to an account designated by the Participant, or (B) delivered to the Participant in the form of a properly executed certificate or certificates

10

representing such shares of Stock. If shares of Stock and/or Depositary Shares are used to pay all or part of the aggregate Option Price, the Company shall issue and deliver to the Participant the additional shares of Stock, in excess of the aggregate Option Price or portion thereof paid using shares of Stock or Depositary Shares, to which the Participant is entitled as a result of the Option exercise. If the Participant exercising an Option (x) is eligible for participation in the Deferred Delivery Plan, (y) pays the aggregate Option Price pursuant to 7(g)(iii)(A), (B), (C), (D) or (E) below, and (z) has made an irrevocable election at least six months prior to the Exercise Date as required under the Deferred Delivery Plan, the income resulting from the Option exercise shall be deferred into the Participant's Deferred Delivery Plan account and no additional shares of Stock shall be delivered to the Participant.

(iii) the aggregate Option Price shall be paid by any of the following methods or any combination of the following methods:

(A) in cash, including the wire transfer of funds in U.S. dollars to one of the Company's bank accounts located in the United States, with such bank account to be designated from time to time by the Company;

(B) by personal, certified or cashier's check payable in U.S. dollars to the order of the Company;

(C) by delivery to the Company or the Administrative Agent of certificates representing a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, properly endorsed for transfer to the Company; provided that the shares of Stock used for this purpose must have been owned by the Participant for a period of at least six months;

(D) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of the number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the shares of Stock and/or Depositary Shares used for this purpose have been owned by the Participant for a period of at least six months;

(E) if the income resulting from the Option exercise is to be deferred into the Participant's Deferred Delivery Plan account, by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of vested Stock Units held in the Participant's Deferred Delivery Plan account, the equivalent aggregate Fair

11

Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the Stock Units used for this purpose were vested as of the Exercise Date; or

(F) by delivery to the Company or the Administrative Agent of a properly executed notice of exercise together with irrevocable instructions to a broker to promptly deliver to the Company, by wire transfer or check as noted in (A) and (B) above, the amount of the proceeds of the sale of all or a portion of the Stock or of a loan from the broker to the Option Holder necessary to pay the aggregate Option Price.

(iv) For purposes of the Plan, the income resulting from an Option exercise shall be based on the Fair Market Value of the Stock for the Exercise Date; however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) hereof, the Fair Market Value shall be deemed to be the per share sale price and the Exercise Date shall be deemed to be the date of such sale.

(h) Date of Grant. An option shall be considered as having been granted on the date specified in the grant resolution of the Committee.

(i) Tax Withholding. Each Stock Option Agreement shall provide that, upon exercise of the Option, the Participant shall make appropriate arrangements with the Company to provide for the amount of tax withholding required by Sections 3102 and 3402 or any successor section(s) of the Internal Revenue Code and applicable state and local income tax laws, including payment of such taxes in cash, by check or as provided in Section 13.2 hereof.

(j) Adjustment of Options. Subject to the provisions of Sections 4, 5, 7, 8 and 12, the Committee may make any adjustment in the number of shares covered by, or the terms of an outstanding Option and a subsequent granting of an Option, by amendment or by substitution of an outstanding Option; however, except as provided in Sections 4, 5, 8 and 12 hereof, the Committee may not adjust the exercise price of any outstanding Option. Such amendment or substitution may result in terms and conditions (including the number of shares covered, vesting schedule or exercise period) that differ from the terms and conditions of the original Option. The Committee may not, however, adversely affect the rights of any Participant to previously granted Options without the consent of such Participant. If such action is effected by amendment, the effective date of such amendment will be the date of the original grant.

7.3 Shareholder Privileges. No Option Holder shall have any rights as a shareholder with respect to any shares of Stock covered by an Option until the Option Holder becomes the holder of record of such Stock, and no adjustments

12

shall be made for dividends or other distributions or other rights as to which there is a record date preceding the date such Option Holder becomes the holder of record of such Stock, except as provided in Section 4.

SECTION 8

CHANGE OF CONTROL

8.1 In General. In the event of the occurrence of a change of control of the Company, as defined in Section 8.3 hereof, all outstanding Options shall become automatically vested, without further action by the Committee or the Board, so as to make all such Options fully vested and exercisable as of the date of such change of control.

8.2 Limitation on Payments. If the provisions of this Section 8 would result in the receipt by any Participant of a payment within the meaning of Section 280G of the Internal Revenue Code and the regulations promulgated thereunder and if the receipt of such payment by any Participant would, in the opinion of independent tax counsel of recognized standing selected by the Company, result in the payment by such Participant of any excise tax provided for in Sections 280G and 4999 of the Internal Revenue Code, then the amount of such payment shall be reduced to the extent required, in the opinion of independent tax counsel, to prevent the imposition of such excise tax; provided, however, that the Committee, in its sole discretion, may authorize the payment of all or any portion of the amount of such reduction to the Participant.

8.3 Definition. For purposes of the Plan, a "change of control" shall mean any of the events specified in the Company's Income Continuance Plan which constitute a change of control within the meaning of that Plan.

SECTION 9

RIGHTS OF EMPLOYEES, PARTICIPANTS

9.1 Employment. Nothing contained in the Plan or in any Option granted under the Plan shall confer upon any Participant any right with respect to the continuation of his or her employment by the Company or any Affiliated Corporation, or interfere in any way with the right of the Company or any Affiliated Corporation, subject to the terms of any separate employment agreement to the contrary, at any time to terminate such employment or to increase or decrease the compensation of the Participant from the rate in existence at the time of the grant of an Option. Whether an authorized leave of absence, or absence in military or government service, shall constitute a termination of employment shall be determined by the Committee at the time.

13

9.2 Nontransferability. No right or interest of any Participant in an Option granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Participant, either voluntarily or involuntarily, or subjected to any lien, directly or indirectly, by operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy. In the event of a Participant's death, a Participant's rights and interests in Options shall, to the extent provided in Section 7, be transferable by testamentary will or the laws of descent and distribution, and payment of any amounts due under the Plan shall be made to, and exercise of any Options may be made by, the Participant's legal representatives, heirs or legatees. If, in the opinion of the Committee, a person entitled to payments or to exercise rights with respect to the Plan is disabled from caring for his affairs because of mental condition, physical condition or age, payment due such person may be made to, and such rights shall be exercised by, such person's guardian, conservator or other legal personal representative upon furnishing the Committee with evidence of such status satisfactory to the Committee.

SECTION 10

GENERAL RESTRICTIONS

10.1 Investment Representations. The Company may require any person to whom an Option is granted, as a condition of exercising such Option, to give written assurances in substance and form satisfactory to the Company and its counsel to the effect that such person is acquiring the Stock subject to the Option for his own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with Federal and applicable state securities laws.

10.2 Compliance with Securities Laws. Each Option shall be subject to the requirement that, if at any time counsel to the Company shall determine that the listing, registration or qualification of the shares subject to such Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, is necessary as a condition of, or in connection with, the issuance or purchase of shares thereunder, such Option may not be accepted or exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained on conditions acceptable to the Committee. Nothing herein shall be deemed to require the Company to apply for or to obtain such listing, registration or qualification.

14

SECTION 11

OTHER EMPLOYEE BENEFITS

The amount of any income deemed to be received by a Participant as a result of an Option exercise shall not constitute "earnings" or "compensation" with respect to which any other employee benefits of such employee are determined including, without limitation benefits under any pension, profit sharing, life insurance or salary continuation plan.

SECTION 12

PLAN AMENDMENT, MODIFICATION AND TERMINATION

The Board may at any time terminate, and from time to time may amend or modify the Plan provided, however, that no amendment or modification may become effective without approval of the amendment or modification by the shareholders if shareholder approval is required to enable the Plan to satisfy any applicable statutory or regulatory requirements unless the Company, on the advice of counsel, determines that shareholder approval is otherwise necessary or desirable.

No amendment, modification or termination of the Plan shall in any manner adversely affect any Options theretofore granted under the Plan, without the consent of the Participant holding such Options.

The Committee shall have the authority to adopt such modifications, procedures and subplans as may be necessary or desirable to comply with the provisions of the laws (including, but not limited to, tax laws and regulations) of countries other than the United States in which the Company may operate, so as to assure the viability of the benefits of the Plan to Participants employed in such countries.

15

SECTION 13

(d) by the Company or the Administrative Agent withholding from the shares of Stock otherwise issuable to the Participant upon exercise of the Option, a number of shares of Stock, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required to be withheld. Any such elections by Participants to have shares of Stock withheld for this purpose will be subject to the following restrictions:

16

(i) all elections shall be made on or prior to the Exercise Date; and

(ii) all elections shall be irrevocable.

13.3 Excess Withholding. At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay additional or excess amounts of tax withholding, beyond the required amounts and up to the Participant's marginal tax rate:

(a) by delivery to the Company or the Administrative Agent of a number of Shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than such excess withholding amount, provided that such shares of Stock have been owned by the Participant for a period of at least six month; or

(b) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than such excess withholding amount, provided that such shares of Stock and/or Depositary Shares have been owned by the Participant for a period of at least six months.

13.4 Section 16 Requirements. If the Participant is an officer or director of the Company within the meaning of Section 16 or any successor section(s) of the 1934 Act ("Section 16"), the Participant must satisfy the requirements of such

Such conditions are hereby incorporated herein by reference and shall be set forth in the Stock Option Agreement with the Participant which describes the Option.

17

14.3 Governing Law. The Plan and all agreements hereunder shall be construed in accordance with and governed by the laws of the State of Texas.

DURATION OF THE PLAN

The Plan shall terminate at such time as may be determined by the Board of Directors, and no Option shall be granted after such termination. If not sooner terminated under the preceding sentence, the Plan shall fully cease and expire at midnight on September 18, 1995. Options outstanding at the time of the Plan termination may continue to be exercisable in accordance with the Stock Option Agreement pertaining to each such Option.

APACHE CORPORATION
1995 STOCK OPTION PLAN

(AS AMENDED AND RESTATED SEPTEMBER 13, 2001)

SECTION 1

INTRODUCTION

1.1 Establishment. Apache Corporation, a Delaware corporation (hereinafter referred to, together with its Affiliated Corporations (as defined in Section 2.1 hereof) as the "Company" except where the context otherwise requires), hereby establishes the Apache Corporation 1995 Stock Option Plan (the "Plan") for certain key employees of the Company. The Plan permits the grant of stock options to certain key employees of the Company.

1.2 Purposes. The purposes of the Plan are to provide the key management employees selected for participation in the Plan with added incentives to continue in the long-term service of the Company and to create in such employees a more direct interest in the future success of the operations of the Company by relating incentive compensation to increases in stockholder value, so that the income of the key management employees is more closely aligned with the interests of the Company's stockholders. The Plan is also designed to attract key employees and to retain and motivate participating employees by providing an opportunity for investment in the Company.

The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan, or in any agreement entered into hereunder, in the manner and to the extent it shall deem expedient and it shall be the sole and final judge of such expediency. No member of the Committee shall be liable for any action or determination made in good faith.

In accordance with this intent, the amount of income a Participant may receive from Options granted under the Plan shall be based solely on an increase in the value of the Stock after the date of the grant of the Option, or such other bases as may be permitted by applicable law. The Committee is authorized to take such additional action, if any, that may be required to ensure that the Plan satisfies the requirements of Section 162 and the regulations promulgated or revenue rulings published thereunder.

SECTION 4

STOCK SUBJECT TO THE PLAN

4.1 Number of Shares. Subject to Section 7.1 and to adjustment pursuant to
Section 4.3 hereof, two million five hundred thousand (2,500,000) shares of Stock are authorized for issuance under the Plan in accordance with the provisions of the Plan and subject to such restrictions or other provisions as the Committee may from time to time deem necessary. This authorization may be increased from time to time by approval of the Board and the stockholders of the Company if, on the advice of counsel for the Company, such stockholder approval is required. Shares of Stock which may be issued upon exercise of Options shall be applied to reduce the maximum number of shares of Stock remaining available for use under the Plan. The Company shall at all times during the term of the Plan and while any Options are outstanding retain as authorized and unissued Stock, or as Stock in the Company's treasury, at least the number of shares from time to time required under the provisions of the Plan, or otherwise assure itself of its ability to perform its obligations hereunder.

4

4.2 Other Shares of Stock. Any shares of Stock that are subject to an Option which expires, is forfeited, is cancelled, or for any reason is terminated unexercised, and any shares of Stock that for any other reason are not issued to a Participant or are forfeited shall automatically become available for use under the Plan.

4.3 Adjustments for Stock Split, Stock Dividend, etc. If the Company shall at any time increase or decrease the number of its outstanding shares of Stock or change in any way the rights and privileges of such shares by means of the payment of a Stock dividend or any other distribution upon such shares payable in Stock, or through a Stock split, subdivision, consolidation, combination, reclassification or recapitalization involving the Stock then in relation to the Stock that is affected by one or more of the above events, the numbers, rights and privileges of the following shall be, in each case, equitably and proportionally adjusted to take into account the occurrence of any of the above events, (i) the shares of Stock as to which Options may be granted under the Plan; (ii) the shares of Stock then included in each outstanding Option granted hereunder; and (iii) the Option Price for each outstanding Option granted hereunder.

4.4 Dividend Payable in Stock of Another Corporation, Etc. If the Company shall at any time pay or make any dividend or other distribution upon the Stock payable in securities or other property (except money or Stock), a proportionate part of such securities or other property shall be set aside and delivered to any Participant then holding an Option for the particular type of Stock for which the dividend or other distribution was made, upon exercise thereof. Prior to the time that any such securities or other property are delivered to a Participant in accordance with the foregoing, the Company shall be the owner of such securities or other property and shall have the right to vote the securities, receive any dividends payable on such securities, and in all other respects shall be treated as the owner. If securities or other property which have been set aside by the Company in accordance with this Section are not delivered to a Participant because an Option is not exercised, then such securities or other property shall remain the property of the Company and shall be dealt with by the Company as it shall determine in its sole discretion.

4.5 Other Changes in Stock. In the event there shall be any change, other than as specified in Sections 4.3 and 4.4 hereof, in the number or kind of outstanding shares of Stock or of any stock or other securities into which the Stock shall be changed or for which it shall have been exchanged, and if the Committee shall in its discretion determine that such change equitably requires an adjustment in the number or kind of shares subject to outstanding Options or which have been reserved for issuance pursuant to the Plan but are not then subject to an Option, then such adjustments shall be made by the Committee and shall be effective for all purposes of the Plan and on each outstanding Option that involves the particular type of stock for which a change was effected.

5

4.6 Rights to Subscribe. If the Company shall at any time grant to the holders of its Stock rights to subscribe pro rata for additional shares thereof or for any other securities of the Company or of any other corporation, there shall be reserved with respect to the shares then under Option to any Participant of the particular class of Stock involved the Stock or other securities which the Participant would have been entitled to subscribe for if immediately prior to such grant the Participant had exercised his entire Option. If, upon exercise of any such Option, the Participant subscribes for the additional shares or other securities, the aggregate Option Price shall be increased by the amount of the price that is payable by the Participant for such additional shares or other securities.

4.7 General Adjustment Rules. No adjustment or substitution provided for in this
Section 4 shall require the Company to sell a fractional share of Stock under any Option, or otherwise issue a fractional share of Stock, and the total substitution or adjustment with respect to each Option shall be limited by deleting any fractional share. In the case of any such substitution or adjustment, the aggregate Option Price for the shares of Stock then subject to the Option shall remain unchanged but the Option Price per share under each such Option shall be equitably adjusted by the Committee to reflect the greater or lesser number of shares of Stock or other securities into which the Stock subject to the Option may have been changed.

4.8 Determination by the Committee, Etc. Adjustments under this Section 4 shall be made by the Committee, whose determinations with regard thereto shall be final and binding upon all parties.

SECTION 5

REORGANIZATION OR LIQUIDATION

In the event that the Company is merged or consolidated with another corporation and the Company is not the surviving corporation, or if all or substantially all of the assets or more than 20 percent of the outstanding voting stock of the Company is acquired by any other corporation, business entity or person, or in case of a reorganization (other than a reorganization under the United States Bankruptcy Code) or liquidation of the Company, and if the provisions of Section 8 hereof do not apply, the Committee, or the board of directors of any corporation assuming the obligations of the Company, shall, as to the Plan and outstanding Options either (i) make appropriate provision for the adoption and continuation of the Plan by the acquiring or successor corporation and for the protection of any such outstanding Options by the substitution on an equitable basis of appropriate stock of the Company or of the merged, consolidated or otherwise reorganized corporation which will be issuable with respect to the Stock, provided that no

6

additional benefits shall be conferred upon the Participants holding such Options as a result of such substitution, and the excess of the aggregate Fair Market Value of the shares subject to the Options immediately after such substitution over the aggregate Option Price thereof is not more than the excess of the aggregate Fair Market Value of the shares subject to such Options immediately before such substitution over the aggregate Option Price thereof, or
(ii) upon written notice to the Participants, provide that all unexercised Options shall be exercised within a specified number of days of the date of such notice or such Options will be terminated. In the latter event, the Committee shall accelerate the vesting dates of outstanding Options so that all Options become fully vested and exercisable prior to any such event.

SECTION 6

PARTICIPATION

Participants in the Plan shall be those Eligible Employees who, in the judgment of the Committee, are performing, or during the term of their incentive arrangement will perform, vital services in the management, operation and development of the Company or an Affiliated Corporation, and significantly contribute, or are expected to significantly contribute, to the achievement of the Company's long-term corporate economic objectives. Participants may be granted from time to time one or more Options; provided, however, that the grant of each such Option shall be separately approved by the Committee, and receipt of one such Option shall not result in automatic receipt of any other Option. Upon determination by the Committee that an Option is to be granted to a Participant, written notice shall be given to such person, specifying the terms, conditions, rights and duties related thereto. Each Participant shall, if required by the Committee, enter into an agreement with the Company, in such form as the Committee shall determine and which is consistent with the provisions of the Plan, specifying such terms, conditions, rights and duties. Options shall be deemed to be granted as of the date specified in the grant resolution of the Committee, which date shall be the date of any related agreement with the Participant. In the event of any inconsistency between the provisions of the Plan and any such agreement entered into hereunder, the provisions of the Plan shall govern.

SECTION 7

STOCK OPTIONS

7.1 Grant of Stock Options. Coincident with or following designation for participation in the Plan, an Eligible Employee may be granted one or more Options. Grants of Options under the Plan shall be made by the Committee. In no event shall the exercise of one Option affect the right to exercise any other Option or affect the number of shares of Stock for which any other Option may be

7

exercised, except as provided in subsection 7.2(j) hereof. During the life of the Plan, no Eligible Employee may be granted Options which in the aggregate pertain to in excess of 25 percent of the total shares of Stock authorized under the Plan.

7.2 Stock Option Agreements. Each Option granted under the Plan shall be evidenced by a written stock option agreement which shall be entered into by the Company and the Participant to whom the Option is granted (the "Stock Option Agreement"), and which shall contain the following terms and conditions, as well as such other terms and conditions, not inconsistent therewith, as the Committee may consider appropriate in each case.

(a) Number of Shares. Each Stock Option Agreement shall state that it covers a specified number of shares of Stock, as determined by the Committee.

(b) Price. The price at which each share of Stock covered by an Option may be purchased shall be determined in each case by the Committee and set forth in the Stock Option Agreement, but in no event shall the price be less than the Fair Market Value of the Stock on the date the Option is granted.

(c) Duration of Options; Employment Required For Exercise. Each Stock Option Agreement shall state the period of time, determined by the Committee, within which the Option may be exercised by the Participant (the "Option Period"). The Option Period must end, in all cases, not more than ten years from the date an Option is granted. Except as otherwise provided in Sections 5 and 8 and subsection 7.2(d)(iv) hereof, each Option granted under the Plan shall become exercisable in increments such that 25 percent of the Option will become exercisable on each of the four subsequent one-year anniversaries of the date the Option is granted, but each such additional 25-percent increment shall become exercisable only if the Participant has been continuously employed by the Company from the date the Option is granted through the date on which each such additional 25-percent increment becomes exercisable.

(d) Termination of Employment, Death, Disability, Etc. Each Stock Option Agreement shall provide as follows with respect to the exercise of the Option upon termination of the employment or the death of the Participant:

(i) If the employment of the Participant by the Company is terminated within the Option Period for cause, as determined by the Company, the Option shall thereafter be void for all purposes. As used in this subsection 7.2(d), "cause" shall mean a gross violation, as determined by the Company, of the Company's established policies and procedures, provided that the effect of this subsection 7.2(d) shall be limited to determining the consequences of a termination and that nothing in this subsection 7.2(d) shall restrict or otherwise

8

interfere with the Company's discretion with respect to the termination of any employee.

(ii) If the Participant retires from employment by the Company on or after attaining age 60, the Option may be exercised by the Participant within 36 months following his or her retirement (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such 36-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of the Participant's retirement.

(iii) If the Participant becomes disabled (as determined pursuant to the Company's Long-Term Disability Plan or any successor plan), during the Option Period while still employed, or within the three-month period referred to in (v) below, or within the 36-month period referred to in (ii) above, the Option may be exercised by the Participant or by his or her guardian or legal representative, within twelve months following the Participant's disability, or within the 36-month period referred to in (ii) if applicable and if longer (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such twelve-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares of Stock as to which the Option had become exercisable on or before the date of the Participant's disability.

(iv) In the event of the Participant's death while still employed by the Company, each Option of the deceased Participant may be exercised by those entitled to do so under the Participant's will or under the laws of descent and distribution within twelve months following the Participant's death (provided that in any event such exercise must occur within the Option Period), but not thereafter, as to all shares of Stock which are subject to such Option, including each 25-percent increment of the Option, if any, which has not yet become exercisable at the time of the Participant's death. In the event of the Participant's death within the 36-month period referred to in (ii) above or within the twelve-month period referred to in (iii) above, each Option of the deceased Participant that is exercisable at the time of death may be exercised by those entitled to do so under the Participant's will or under the laws of descent and distribution within twelve months following the Participant's death or within the 36-month period referred to in (ii), if applicable and if longer (provided that in any event such exercise must occur within the Option Period). The provisions of this paragraph (iv) of subsection 7.2(d) shall be applicable to each Stock Option Agreement as if set forth therein word for word. Each Stock Option Agreement executed by the Company prior to the adoption of this provision shall be deemed amended to

9

include the provisions of this paragraph and all Options granted pursuant to such Stock Option Agreements shall be exercisable as provided herein.

(v) If the employment of the Participant by the Company is terminated (which for this purpose means that the Participant is no longer employed by the Company or by an Affiliated Corporation) within the Option Period for any reason other than cause, the Participant's retirement on or after attaining age 60, the Participant's disability or death, the Option may be exercised by the Participant within three months following the date of such termination (provided that such exercise must occur within the Option Period), but not thereafter. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of termination of the Participant's employment.

(e) Transferability. Each Stock Option Agreement shall provide that the Option granted therein is not transferable by the Participant except by will or pursuant to the laws of descent and distribution, and that such Option is exercisable during the Participant's lifetime only by him or her, or in the event of the Participant's disability or incapacity, by his or her guardian or legal representative.

(f) Agreement to Continue in Employment. Each Stock Option Agreement shall contain the Participant's agreement to remain in the employment of the Company, at the pleasure of the Company, for a continuous period of at least one year after the date of such Stock Option Agreement, at the salary rate in effect on the date of such agreement or at such changed rate as may be fixed, from time to time, by the Company.

(g) Exercise, Payments, Etc.

(i) Each Stock Option Agreement shall provide that the method for exercising the Option granted therein shall be by delivery to the Office of the Secretary of the Company or to the Administrative Agent of written notice specifying the number of shares of Stock with respect to which such Option is exercised and payment to the Company of the aggregate Option Price. Such notice shall be in a form satisfactory to the Committee and shall specify the particular Options (or portions thereof) which are being exercised and the number of shares of Stock with respect to which the Options are being exercised. The exercise of the Option shall be deemed effective on the date such notice is received by the Office of the Secretary or by the Administrative Agent and payment is made to the Company of the aggregate Option Price (the "Exercise Date"); however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) below, the Exercise Date shall be deemed to be the date of such sale. If requested by the Company, such notice shall contain the Participant's representation that he or she

10

is purchasing the Stock for investment purposes only and his or her agreement not to sell any Stock so purchased in any manner that is in violation of the Securities Act of 1933, as amended, or any applicable state law, and such restriction, or notice thereof, shall be placed on the certificates representing the Stock so purchased. The purchase of such Stock shall take place upon delivery of such notice to the Office of the Secretary of the Company or to the Administrative Agent, at which time the aggregate Option Price shall be paid in full to the Company by any of the methods or any combination of the methods set forth in 7.2(g)(iii) below.

(ii) Except as referenced below in connection with the Deferred Delivery Plan, the shares of Stock to which the Participant is entitled as a result of the exercise of the Option shall be issued by the Company and (A) delivered by electronic means to an account designated by the Participant, or (B) delivered to the Participant in the form of a properly executed certificate or certificates representing such shares of Stock. If shares of Stock and/or Depositary Shares are used to pay all or part of the aggregate Option Price, the Company shall issue and deliver to the Participant the additional shares of Stock, in excess of the aggregate Option Price or portion thereof paid using shares of Stock or Depositary Shares, to which the Participant is entitled as a result of the Option exercise. If the Participant exercising an Option (x) is eligible for participation in the Deferred Delivery Plan, (y) pays the aggregate Option Price pursuant to 7.2(g)(iii)(A), (B), (C), (D) or (E) below, and (z) has made an irrevocable election at least six months prior to the Exercise Date as required under the Deferred Delivery Plan, the income resulting from the Option exercise shall be deferred into the Participant's Deferred Delivery Plan account and no additional shares of Stock shall be delivered to the Participant.

(iii) the aggregate Option Price shall be paid by any of the following methods or any combination of the following methods:

(A) in cash, including the wire transfer of funds in U.S. dollars to one of the Company's bank accounts located in the United States, with such bank account to be designated from time to time by the Company;

(B) by personal, certified or cashier's check payable in U.S. dollars to the order of the Company;

(C) by delivery to the Company or the Administrative Agent of certificates representing a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, properly endorsed for transfer to the Company; provided that the shares of Stock used for this purpose must have been owned by the Participant for a period of at least six months;

11

(D) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership as of the Exercise Date of the number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the shares of Stock and/or Depositary Shares used for this purpose have been owned by the Participant for a period of at least six months;

(E) if the income resulting from the Option exercise is to be deferred into the Participant's Deferred Delivery Plan account, by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of vested Stock Units held in the Participant's Deferred Delivery Plan account, the equivalent aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the Stock Units used for this purpose were vested as of the Exercise Date; or

(F) by delivery to the Company or the Administrative Agent of a properly executed notice of exercise together with irrevocable instructions to a broker to promptly deliver to the Company, by wire transfer or check as noted in (A) and (B) above, the amount of the proceeds of the sale of all or a portion of the Stock or of a loan from the broker to the Participant necessary to pay the aggregate Option Price.

(iv) For purposes of the Plan, the income resulting from an Option exercise shall be based on the Fair Market Value of the Stock for the Exercise Date; however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) hereof, the Fair Market Value shall be deemed to be the per share sale price and the Exercise Date shall be deemed to be the date of such sale.

(h) Date of Grant. An Option shall be considered as having been granted on the date specified in the grant resolution of the Committee.

(i) Tax Withholding. Each Stock Option Agreement shall provide that, upon exercise of the Option, the Participant shall make appropriate arrangements with the Company to provide for the amount of tax withholding required by Sections 3102 and 3402 or any successor section(s) of the Internal Revenue Code and applicable state and local income tax laws, including payment of such taxes in cash, by check or as provided in Section 13.2 hereof.

(j) Adjustment of Options. Subject to the provisions of Sections 4, 5, 7, 8 and 12 hereof, the Committee may make any adjustment in the number of shares of Stock covered by, or the terms of an outstanding Option and a

12

subsequent granting of an Option, by amendment or by substitution for an outstanding Option; however, except as provided in Sections 4, 5, 8 and 12 hereof, the Committee may not adjust the Option Price of any outstanding Option. Such amendment or substitution may result in terms and conditions (including the number of shares of Stock covered, vesting schedule or Option Period) that differ from the terms and conditions of the original Option. The Committee may not, however, adversely affect the rights of any Participant to previously granted Options without the consent of such Participant. If such action is effected by amendment, the effective date of such amendment will be the date of grant of the original Option.

7.3 Stockholder Privileges. No Participant shall have any rights as a stockholder with respect to any shares of Stock covered by an Option until the Participant becomes the holder of record of such Stock. Except as provided in
Section 4 hereof, no adjustments shall be made for dividends or other distributions or other rights as to which there is a record date preceding the date on which such Participant becomes the holder of record of such Stock.

SECTION 8

CHANGE OF CONTROL

8.1 In General. In the event of the occurrence of a change of control of the Company, as defined in Section 8.3 hereof, all outstanding Options shall become automatically vested, without further action by the Committee or the Board, so as to make all such Options fully vested and exercisable as of the date of such change of control.

8.2 Limitation on Payments. If the provisions of this Section 8 would result in the receipt by any Participant of a payment within the meaning of Section 280G or any successor section(s) of the Internal Revenue Code, and the regulations promulgated thereunder, and if the receipt of such payment by any Participant would, in the opinion of independent tax counsel of recognized standing selected by the Company, result in the payment by such Participant of any excise tax provided for in Sections 280G and 4999 or any successor section(s) of the Internal Revenue Code, then the amount of such payment shall be reduced to the extent required, in the opinion of independent tax counsel, to prevent the imposition of such excise tax; provided, however, that the Committee, in its sole discretion, may authorize the payment of all or any portion of the amount of such reduction to the Participant.

8.3 Definition. For purposes of the Plan, a "change of control" shall mean any of the events specified in the Company's Income Continuance Plan or any successor plan which constitute a change of control within the meaning of such plan.

13

SECTION 9

RIGHTS OF EMPLOYEES, PARTICIPANTS

9.1 Employment. Nothing contained in the Plan or in any Option granted under the Plan shall confer upon any Participant any right with respect to the continuation of his or her employment by the Company or any Affiliated Corporation, or interfere in any way with the right of the Company or any Affiliated Corporation, subject to the terms of any separate employment agreement to the contrary, at any time to terminate such employment or to increase or decrease the level of the Participant's compensation from the level in existence at the time of the grant of an Option. Whether an authorized leave of absence, or absence in military or government service, shall constitute a termination of employment shall be determined by the Committee at the time.

9.2 Nontransferability. No right or interest of any Participant in an Option granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Participant, either voluntarily or involuntarily, or subjected to any lien, directly or indirectly, by operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy. In the event of a Participant's death, a Participant's rights and interests in Options shall, to the extent provided in Section 7 hereof, be transferable by testamentary will or the laws of descent and distribution, and payment of any amounts due under the Plan shall be made to, and exercise of any Options may be made by, the Participant's legal representatives, heirs or legatees. If in the opinion of the Committee, a person entitled to payments or to exercise rights with respect to the Plan is disabled from caring for his or her affairs because of mental condition, physical condition or age, payment due such person may be made to, and such rights shall be exercised by, such person's guardian, conservator or other legal personal representative upon furnishing the Committee with evidence of such status satisfactory to the Committee.

SECTION 10

GENERAL RESTRICTIONS

10.1 Investment Representations. The Company may require a Participant, as a condition of exercising an Option, to give written assurances in substance and form satisfactory to the Company and its counsel to the effect that such person is acquiring the Stock subject to the Option for his own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with federal and applicable state securities laws.

14

10.2 Compliance with Securities Laws. Each Option shall be subject to the requirement that, if at any time counsel to the Company shall determine that the listing, registration or qualification of the shares of Stock subject to such Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, is necessary as a condition of, or in connection with, the issuance or purchase of shares of Stock thereunder, such Option may not be accepted or exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained on conditions acceptable to the Committee. Nothing herein shall be deemed to require the Company to apply for or to obtain such listing, registration, qualification, consent or approval.

SECTION 11

OTHER EMPLOYEE BENEFITS

The amount of any income deemed to be received by a Participant as a result of an Option exercise shall not constitute "earnings" or "compensation" with respect to which any other employee benefits of such Participant are determined including, without limitation benefits under any pension, profit sharing, life insurance or salary continuation plan.

SECTION 12

PLAN AMENDMENT, MODIFICATION AND TERMINATION

The Board may at any time terminate, and from time to time may amend or modify the Plan provided, however, that no amendment or modification may become effective without approval of the amendment or modification by the Company's stockholders if stockholder approval is required to enable the Plan to satisfy any applicable statutory or regulatory requirements unless the Company, on the advice of counsel, determines that stockholder approval is otherwise necessary or desirable.

No amendment, modification or termination of the Plan shall in any manner adversely affect any Option theretofore granted under the Plan, without the consent of the Participant holding such Option.

The Committee shall have the authority to adopt such modifications, procedures and subplans as may be necessary or desirable to comply with the provisions of the laws (including, but not limited to, tax laws and regulations) of countries other than the United States in which the Company may operate, so as to assure the viability of the benefits of the Plan to Participants employed in such countries.

15

SECTION 13

WITHHOLDING

The Committee shall determine the form or forms of the Option Agreements with Participants which shall evidence the particular provisions, terms, conditions, rights and duties of the Company and the Participants with respect to Options granted pursuant to the Plan, which provisions need not be identical except as may be provided herein.

(b) The Committee may from time to time adopt such rules and regulations for carrying out the purposes of the Plan as it may deem proper and in the best interests of the Company. The Committee may appoint an Administrative Agent, who need not be a member of the Committee or an employee of the Company, to assist the Committee in administration of the Plan and to whom it may delegate such powers as the Committee deems appropriate, except that the Committee shall determine any dispute. The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan, or in any agreement entered into hereunder, in the manner and to the extent it shall deem expedient and it shall be the sole and final judge of such expediency. No member of the Committee shall be liable for any action or determination made in good faith. The determinations, interpretations and other actions of the Committee pursuant to the provisions of the Plan shall be binding and conclusive for all purposes and on all persons.

SECTION 4

STOCK SUBJECT TO THE PLAN

4.1 Number of Shares. Subject to Section 7.1 and Section 4.3, one million three hundred thousand (1,300,000) shares of Stock are authorized for issuance under the Plan in accordance with its terms and subject to such restrictions or other provisions as the Committee may from time to time deem necessary. This

4

authorization may be increased from time to time by approval of the Board and the stockholders of the Company if, on the advice of counsel for the Company, such stockholder approval is required. Shares of Stock which may be issued pursuant to the terms of the Options granted hereunder shall be applied to reduce the maximum number of shares of Stock remaining available for use under the Plan. The Company shall at all times during the term of the Plan and while any Options are outstanding retain as authorized and unissued Stock and/or Stock in the Company's treasury, at least the number of shares from time to time required under the provisions of the Plan, or otherwise assure itself of its ability to perform its obligations hereunder.

4.2 Other Shares of Stock. Any shares of Stock that are subject to an Option which expires, is forfeited, is canceled, or for any reason is terminated, and any shares of Stock that for any other reason are not issued to a Participant or are forfeited shall automatically become available for use under the Plan.

4.3 Adjustments for Stock Split, Stock Dividend, etc. If the Company shall at any time increase or decrease the number of its outstanding shares of Stock or change in any way the rights and privileges of such shares by means of the payment of a Stock dividend or any other distribution upon such shares payable in Stock, or through a Stock split, subdivision, consolidation, combination, reclassification or recapitalization involving the Stock then in relation to the Stock that is affected by one or more of the above events, the numbers, rights and privileges of the following shall be, in each case, equitably and proportionally adjusted to take into account the occurrence of any of the above events, (i) the shares of Stock as to which Options may be granted under the Plan; (ii) the shares of Stock then included in each outstanding Option granted hereunder; and (iii) the Option Price for each outstanding Option granted hereunder.

4.4 Dividend Payable in Stock of Another Corporation. If the Company shall at any time pay or make any dividend or other distribution upon the Stock payable in securities or other property (except money or Stock), a proportionate part of such securities or other property shall be set aside and delivered to any Participant then holding an Option for the particular type of Stock for which the dividend or other distribution was made, upon exercise thereof. Prior to the time that any such securities or other property are delivered to a Participant in accordance with the foregoing, the Company shall be the owner of such securities or other property, and in all other respects shall be treated as the owner. If securities or other property which have been set aside by the Company in accordance with this Section are not delivered to a Participant because an Option is not exercised, then such securities or other property shall remain the property of the Company and shall be dealt with by the Company as it shall determine in its sole discretion.

5

4.5 Other Changes in Stock. In the event there shall be any change, other than as specified in Sections 4.3 and 4.4 hereof, in the number or kind of outstanding shares of Stock or of any stock or other securities into which the Stock shall be changed or for which it shall have been exchanged, and if the Committee shall in its discretion determine that such change equitably requires an adjustment in the number or kind of shares subject to outstanding Options or which have been reserved for issuance pursuant to the Plan but are not then subject to an Option, then such adjustments shall be made by the Committee and shall be effective for all purposes of the Plan and on each outstanding Option that involves that particular type of stock for which a change was effected.

4.6 Rights to Subscribe. If the Company shall at any time grant to the holders of its Stock rights to subscribe pro rata for additional shares thereof or for any other securities of the Company or of any other corporation, there shall be reserved with respect to the shares then under Option to any Participant of the particular class of Stock involved the Stock or other securities which the Participant would have been entitled to subscribe for if immediately prior to such grant the Participant had exercised his entire Option. If, upon exercise of any such Option, the Participant subscribes for the additional shares or other securities, the aggregate Option Price shall be increased by the amount of the price that is payable by the Participant for such additional shares or other securities.

4.7 General Adjustment Rules. No adjustment or substitution provided for in this
Section 4 shall require the Company to sell a fractional share of Stock under any Option, or otherwise issue a fractional share of Stock, and the total substitution or adjustment with respect to each Option shall be limited by deleting any fractional share. In the case of any such substitution or adjustment, the aggregate Option Price for the shares of Stock then subject to the Option shall remain unchanged but the Option Price per share under each such Option shall be equitably adjusted by the Committee to reflect the greater or lesser number of shares of Stock or other securities into which the Stock subject to the Option may have been changed.

4.8 Determination by the Committee, etc. Adjustments under this Section 4 shall be made by the Committee, whose determinations with regard thereto shall be final and binding upon all parties.

6

SECTION 5

REORGANIZATION OR LIQUIDATION

In the event that the Company is merged or consolidated with another corporation and the Company is not the surviving corporation, or if all or substantially all of the assets or more than 20 percent of the outstanding voting stock of the Company is acquired by any other corporation, business entity or person, or in case of a reorganization (other than a reorganization under the United States Bankruptcy Code) or liquidation of the Company, and if the provisions of Section 8 hereof do not apply, the Committee, or the board of directors of any corporation assuming the obligations of the Company, shall, as to the Plan and outstanding Options either (i) make appropriate provision for the adoption and continuation of the Plan by the acquiring or successor corporation and for the protection of any such outstanding Options by the substitution on an equitable basis of appropriate stock of the Company or of the merged, consolidated or otherwise reorganized corporation which will be issuable with respect to the Stock, provided that no additional benefits shall be conferred upon the Participants holding such Options as a result of such substitution, and the excess of the aggregate Fair Market Value of the shares subject to such Options immediately after such substitution over the aggregate Option Price thereof is not more than the excess of the aggregate Fair Market Value of the shares subject to such Options immediately before such substitution over the aggregate Option Price thereof, or (ii) upon written notice to the Participants, provide that all unexercised Options shall be exercised within a specified number of days of the date of such notice or such Options will be terminated. In the latter event, the Committee shall accelerate the vesting dates of outstanding Options so that all Options become fully vested and exercisable prior to any such event.

SECTION 6

PARTICIPATION

Participants in the Plan receiving First Category Options may be any Eligible Employee in the discretion of the Committee. Participants in the Plan receiving Second Category Options shall be those Eligible Employees who, in the judgment of the Committee, are performing, or during the term of their incentive arrangement are expected to perform, important services in the management, operation and development of the Company or an Affiliated Corporation, and contribute, or are expected to contribute, to the achievement of the Company's long-term corporate economic objectives. Upon determination by the Committee

7

that an Option is to be granted to a Participant, written notice shall be given to such person, specifying the terms, conditions, rights and duties related thereto. Options shall be deemed to be granted as of the date specified in the granting resolution of the Committee, which date also shall be the date of the Option Agreement with the Participant. In the event of any inconsistency between the provisions of the Plan and any Option Agreement, the provisions of the Plan shall govern.

SECTION 7

OPTIONS

7.1 Grants. Each Participant may be granted only one Option under this Plan. Each Option granted by the Committee shall be evidenced by a written agreement entered into by the Company and the Participant to whom the Option is granted (the "Option Agreement"), which shall contain the terms and conditions set out in this Section 7, as well as such other terms and conditions, not inconsistent therewith, as the Committee may consider appropriate.

7.2 Option Agreements. There shall be two categories of Options issued under this Plan as follows:

(a) The first category of Option ("First Category") shall have a total of two hundred (200) shares of Stock issuable to a Participant upon exercise; and

(b) The second category of Option ("Second Category") shall vary by Participant and, as to any Participant, shall have a total number of shares of Stock issuable upon exercise which equals the sum of the Initial Amount and the Final Amount.

For purposes of this Plan, the term "Initial Amount" means such number of shares (rounded to the nearest full share) which equals not more than one (1) times such Participant's Base Salary divided by the difference between $50 and the Option Price. The term "Final Amount" means such number of shares (rounded to the nearest full share) which equals not more than one and one-half (1.5) times such Participant's Base Salary divided by the difference between $60 and the Option Price.

7.3 Common Terms. Subject to Section 7.2 and Section 7.5, each Option Agreement entered into by the Company and the Participants shall contain at least the following terms and conditions:

8

(a) Number of Shares. Each Option Agreement shall set forth a specified number of shares of Stock issuable upon exercise of the Option, as determined by the Committee pursuant to Section 7.2 hereof.

(b) Price. The exercise price (the "Option Price") at which each share of Stock covered by an Option may be purchased shall be the price specified in the granting resolution of the Committee.

(c) Duration. Each Option Agreement shall state the period of time, determined by the Committee, within which the Option may be exercised (the "Option Period"), which in no event may be greater than ten (10) years.

(d) Vesting. Subject to the provisions of Section 7.3(e) and Section 7.3(f), each Option shall become exercisable in full on the date occurring nine years and six months from the date of grant or such earlier date as the Committee may determine.

(e) Acceleration. Each Option may become exercisable earlier, in increments, upon the occurrence of a Price Threshold Date as follows:

(i) If the Initial Price Threshold Date occurs prior to January 1, 2000:

(A) One-half of the shares of Stock subject to the First Category Options become immediately exercisable as of such date, and

(B) The Initial Amount of shares of Stock subject to each Second Category Option become immediately exercisable as of such date.

(ii) If the Final Price Threshold Date occurs prior to January 1, 2000, the remaining portion of shares of Stock under each category of Option becomes immediately exercisable as of such date.

(f) Termination of Employment, Death, Disability, etc. Subject to the following provisions, each Option Agreement shall state that each Option and the right to acquire stock thereunder shall be subject to the condition that the Participant has remained a full-time employee of the Company from the date of grant of an Option until the applicable exercise date:

(i) If the employment of the Participant by the Company is terminated (which for this purpose means that the Participant is no longer employed by the Company or by an Affiliated Corporation) within the Option Period for any reason other than cause, the Participant's retirement on or after

9

attaining age 60, or the Participant's disability or death, the Option may be exercised by the Participant within three months following the date of such termination (provided that such exercise must occur within the Option Period), but not thereafter. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of termination of the Participant's employment. If the employment of the Participant is terminated within the Option Period for cause, as determined by the Company, any portion of any Option not previously exercised in accordance with this Section 7 shall thereafter be void for all purposes. As used in this subsection, "cause" shall mean a gross violation, as determined by the Company, of the Company's established policies and procedures, provided that the effect of this subsection 7.3(f) shall be limited to determining the consequences of a termination and that nothing in this subsection shall restrict or otherwise interfere with the Company's discretion with respect to the termination of any employee.

(ii) If the Participant retires from employment by the Company on or after attaining age 60, the Option may be exercised by the Participant within 36 months following his or her retirement (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such 36-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case:

(A) If the Participant is holding a First Category Option and the Participant's retirement occurs on or after January 1, 2000, the Option may be exercised as to all shares of Stock which are subject to the Option, including an increment of the Option, if any, which had not otherwise become exercisable on or before the date of the Participant's retirement, or

(B) If the Participant is holding a First Category Option and the Participant's retirement occurs prior to January 1, 2000, the Option may be exercised only as to the shares of Stock as to which the Option had become exercisable on or before the date of the Participant's retirement, or

(C) If the Participant is holding a Second Category Option, the Option may be exercised only as to the shares of Stock as to which the Option had become exercisable on or before the date of the Participant's retirement.

(iii) If the Participant becomes disabled (as determined pursuant to the Company's Long-Term Disability Plan or any successor plan), during the Option Period while still employed, or within the 36-month period referred to in
(ii) above, the Option may be exercised by the Participant or by his or her guardian or legal representative, within twelve months following the Participant's disability,

10

or within the 36-month period referred to in (ii) if applicable and if longer (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such twelve-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares of Stock as to which the Option had become exercisable on or before the date of the Participant's disability.

(iv) In the event of the Participant's death while still employed by the Company, each Option of the deceased Participant may be exercised by those entitled to do so under the Participant's will or under the laws of descent and distribution within twelve months following the Participant's death (provided that in any event such exercise must occur within the Option Period), but not thereafter, as to all shares of Stock which are subject to such Option, including any increment of the Option, if any, which has not yet become exercisable at the time of the Participant's death. In the event of the Participant's death within the 36-month period referred to in (ii) above or within the twelve-month period referred to (iii) above, each Option of the deceased Participant that is exercisable at the time of death may be exercised by those entitled to do so under the Participant's will or under the laws of descent and distribution within twelve months following the Participant's death or within the 36-month period referred to in (ii), if applicable and if longer (provided that in any event such exercise must occur within the Option Period).

(g) Transferability. Each Option Agreement shall state that the Option granted thereunder is not transferable by the Participant, except by will or pursuant to the laws of descent and distribution, and that such Option is exercisable during the Participant's lifetime only by him or her, or in the event of the Participant's disability or incapacity, by his or her guardian or legal representative.

(h) Exercise, Payments, etc.

(i) Each Option Agreement shall provide that the method for exercising the Option granted therein shall be by delivery to the Office of the Secretary of the Company or the Administrative Agent of written notice specifying the number of shares of Stock with respect to which such Option is exercised and payment to the Company of the aggregate Option Price. Such notice shall be in a form satisfactory to the Committee and shall specify the particular Option (or portion thereof) which is being exercised and the number of shares of Stock with respect to which the Option is being exercised. The exercise of the Option shall be deemed effective on the date such notice is received by the Office of the Secretary or the Administrative Agent and payment is made to the Company of

11

the aggregate Option Price (the "Exercise Date"); however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(b)(iii)(E) below, the Exercise Date shall be deemed to be the date of such sale. If requested by the Company, such notice shall contain the Participant's representation that he or she is purchasing the Stock for investment purposes only and his or her agreement not to sell or otherwise distribute any Stock so purchased in any manner that is in violation of the Securities Act of 1933, as amended, or any applicable state law, and such restriction, or notice thereof, shall be placed on the certificates representing the Stock so purchased. The purchase of such Stock shall take place upon delivery of such notice to the Office of the Secretary of the Company or to the Administrative Agent, at which time the Option Price shall be paid in full to the Company by any of the methods or any combination of the methods set forth in 7.2(h)(iii) below.

(ii) The shares of Stock to which the Participant is entitled as a result of the exercise of the Option shall be issued by the Company and (A) delivered by electronic means to an account designated by the Participant, or (B) delivered to the Participant in the form of a properly executed certificate or certificates representing such shares of Stock. If shares of Stock and/or Depositary Shares are used to pay all or part of the aggregate Option Price, the Company shall issue and deliver to the Participant the additional shares of Stock, in excess of the aggregate Option Price or portion thereof paid using shares of Stock or Depositary Shares, to which the Participant is entitled as a result of the Option exercise.

(iii) The aggregate Option Price shall be paid by any of the following methods or any combination of the following methods:

(A) in cash, including the wire transfer of funds in U.S. dollars to one of the Company's bank accounts located in the United States, with such bank account to be designated from time to time by the Company;

(B) by personal, certified or cashier's check payable in U.S. dollars to the order of the Company;

(C) by delivery to the Company or the Administrative Agent of certificates representing a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value (as of the Exercise Date) of which is not greater than the aggregate Option Price of the Option being exercised, properly endorsed for transfer to the Company; provided that the shares of Stock used for this purpose must have been owned by the Participant for a period of at least six months;

12

(D) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership as of the Exercise Date of the number of (1) shares of Stock and/or (2) Depositary Shares, the aggregate Fair Market Value (as of the Exercise Date) of which is not greater than the aggregate Option Price of the Option being exercised; provided that the shares of Stock and/or Depositary Shares used for this purpose must have been owned by the Participant for a period of at least six months; or

(E) by delivery to the Company or the Administrative Agent of a properly executed notice of exercise together with irrevocable instructions to a broker to promptly deliver to the Company, by wire transfer or check as noted in (A) and (B) above, the amount of the proceeds of the sale of all or a portion of the Stock or of a loan from the broker to the Participant necessary to pay the aggregate Option Price.

(iv) For purposes of the Plan, the income resulting from an Option exercise shall be based on the Fair Market Value of the Stock for the Exercise Date; however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(h)(iii)(E) hereof, the Fair Market Value shall be deemed to be the per share sale price and the Exercise Date shall be deemed to be the date of such sale.

7.4 Tax Withholding. Each Option Agreement shall provide that, upon exercise of the Option, the Participant shall make appropriate arrangements with the Company to provide for the amount of additional tax withholding required by Sections 3102 and 3402 or any successor section(s) of the Internal Revenue Code and applicable state and local income tax laws, including payment of such taxes in cash, by check or as provided in Section 13.2 hereof.

7.5 Subsequent Option Agreements. Following the initial grant of Options in 1996, additional Participants may be designated by the Committee for grant of Options substantially in accordance with the above terms and conditions, subject to such changes and modifications to reflect the circumstances of any subsequent grant as the Committee, in its discretion, deems appropriate.

7.6 Stockholder Privileges. No Participant shall have any rights as a stockholder with respect to any shares of Stock covered by an Option until the Participant becomes the holder of record of such Stock. No adjustments shall be made for dividends or other distributions or other rights as to which there is a record date preceding the date on which such Participant becomes the holder of record of such Stock.

13

SECTION 8

CHANGE OF CONTROL

8.1 In General. In the event of the occurrence of a change of control of the Company, as defined in Section 8.3 hereof, all outstanding Options shall become automatically vested, without further action by the Committee or the Board, so as to make all such Options fully vested and exercisable as of the date of such change of control.

8.2 Limitation on Payments. If the provisions of this Section 8 would result in the receipt by any Participant of a payment within the meaning of Section 280G or any successor section(s) of the Internal Revenue Code, and the regulations promulgated thereunder, and if the receipt of such payment by any Participant would, in the opinion of independent tax counsel of recognized standing selected by the Company, result in the payment by such Participant of any excise tax provided for in Sections 280G and 4999 or any successor section(s) of the Internal Revenue Code, then the amount of such payment shall be reduced to the extent required, in the opinion of independent tax counsel, to prevent the imposition of such excise tax; provided, however, that the Committee, in its sole discretion, may authorize the payment of all or any portion of the amount of such reduction to the Participant.

8.3 Definition. For purposes of the Plan, a "change of control" shall mean any of the events specified in the Company's Income Continuance Plan or any successor plan which constitute a change of control within the meaning of such plan.

SECTION 9

RIGHTS OF EMPLOYEES, PARTICIPANTS

9.1 Employment. Nothing contained in the Plan or in any Option granted under the Plan shall confer upon any Participant any right with respect to the continuation of his or her employment by the Company or any Affiliated Corporation, or interfere in any way with the right of the Company or any Affiliated Corporation, subject to the terms of any separate employment agreement to the contrary, at any time to terminate such employment or to increase or decrease the level of the Participant's compensation from the level in existence at the time of the grant of an Option. Whether an authorized leave of absence, or absence

14

in military or government service, shall constitute a termination of employment shall be determined by the Committee at the time.

9.2 Nontransferability. No right or interest of any Participant in an Option granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Participant, either voluntarily or involuntarily, or subjected to any lien, directly or indirectly, by operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy. In the event of a Participant's death, a Participant's rights and interests in Options shall, to the extent provided in Section 7 hereof, be transferable by testamentary will or the laws of descent and distribution, and payment of any amounts due under the Plan shall be made to, and exercise of any Options may be made by, the Participant's legal representatives, heirs or legatees. If in the opinion of the Committee, a person entitled to payments or to exercise rights with respect to the Plan is disabled from caring for his or her affairs because of mental condition, physical condition or age, payment due such person may be made to, and such rights shall be exercised by, such person's guardian, conservator or other legal personal representative upon furnishing the Committee with evidence of such status satisfactory to the Committee.

SECTION 10

GENERAL RESTRICTIONS

10.1 Investment Representations. The Company may require a Participant, as a condition of exercising an Option, to give written assurances in substance and form satisfactory to the Company and its counsel to the effect that such person is acquiring the Stock subject to the Option for his own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with federal and applicable state securities laws.

10.2 Compliance with Securities Laws. Each Option shall be subject to the requirement that, if at any time counsel to the Company shall determine that the listing, registration or qualification of the shares of Stock subject to such Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, is necessary as a condition of, or in connection with, the issuance or purchase of shares of Stock thereunder, such Option may not be accepted or exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained on conditions acceptable to the Committee. Nothing herein shall be

15

deemed to require the Company to apply for or to obtain such listing, registration, qualification, consent or approval.

SECTION 11

OTHER EMPLOYEE BENEFITS

The amount of any income deemed to be received by a Participant as a result of an Option exercise shall not constitute "earnings" or "compensation" with respect to which any other employee benefits of such Participant are determined including, without limitation, benefits under any pension, profit sharing, life insurance or salary continuation plan.

SECTION 12

PLAN AMENDMENT, MODIFICATION AND TERMINATION

The Board may at any time terminate, and from time to time may amend or modify the Plan provided, however, that no amendment or modification may become effective without approval of the amendment or modification by the Company's stockholders if stockholder approval is required to enable the Plan to satisfy any applicable statutory or regulatory requirements, unless the Company, on the advice of counsel, determines that stockholder approval is otherwise necessary.

No amendment, modification or termination of the Plan shall in any manner adversely affect any Option theretofore granted under the Plan, without the consent of the Participant holding such Option.

The Committee shall have the authority to adopt such modifications, procedures and subplans as may be necessary or desirable to comply with the provisions of the laws (including, but not limited to, tax laws and regulations) of countries other than the United States in which the Company may operate, so as to assure the viability of the benefits of the Plan to Participants employed in such countries.

16

13.1 Withholding Requirement. The Company's obligations to deliver shares of Stock upon the exercise of an Option shall be subject to the Participant's satisfaction of all applicable federal, state and local income and other tax withholding requirements.

13.2 Satisfaction of Required Withholding. At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay all such amounts of required tax withholding, or any part thereof:

(a) by the delivery to the Company or the Administrative Agent of a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value (as of the Exercise Date) of which is not greater than the amount required to be withheld, provided that such shares have been held by the Participant for a period of at least six months;

(b) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership as of the Exercise Date of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value (as of the Exercise Date) of which is not greater than the amount required to be withheld, provided that such shares of Stock and/or Depositary Shares have been owned by the Participant for a period of at least six months; or

(c) by the Company or the Administrative Agent withholding from the shares of Stock otherwise issuable to the Participant upon exercise of the Option, a number of shares of Stock, the aggregate Fair Market Value (as of the Exercise Date) of which is not greater than the amount required to be withheld. Any such elections by Participants to have shares of Stock withheld for this purpose will be subject to the following restrictions:

(i) all elections shall be made on or prior to the Exercise Date; and

(ii) all elections shall be irrevocable.

13.3 Excess Withholding. At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay additional or excess amounts of tax withholding, beyond the required amounts and up to the Participant's marginal tax rate:

17

(a) by delivery to the Company or the Administrative Agent of a number of Shares of Stock then owned by the Participant, the aggregate Fair Market Value (as of the Exercise Date) of which is not greater than such excess withholding amount, provided that such shares of Stock have been owned by the Participant for a period of at least six months; or

(b) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership as of the Exercise Date of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value (as of the Exercise Date) of which is not greater than such excess withholding amount, provided that such shares of Stock and/or Depositary Shares have been owned by the Participant for a period of at least six months.

13.4 Section 16 Requirements. If the Participant is an officer or director of the Company within the meaning of Section 16 or any successor section(s) of the 1934 Act ("Section 16"), the Participant must satisfy the requirements of such
Section 16 and any applicable rules and regulations thereunder with respect to the use of shares of Stock and/or Depositary Shares to satisfy such tax withholding obligation.

14.2 Federal Securities Laws Requirements. If, subsequent to the date of grant, a Participant becomes an officer or director of the Company within the meaning of Section 16, Options granted hereunder shall be subject to all conditions required under Rule 16b-3, or any successor rule(s) promulgated under the 1934 Act, to qualify the Option for any exemptions from the provisions of Section 16 available under such Rule. Such conditions are hereby incorporated herein by reference and shall be set forth in the Stock Option Agreement with the Participant which describes the Option.

14.3 Governing Law. The Plan and all Stock Option Agreements hereunder shall be construed in accordance with and governed by the laws of the State of Texas.

18

PLAN ADMINISTRATION

3.1 Administration by the Committee.

The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan, or in any agreement entered into hereunder, in the manner and to the extent it shall deem expedient and it shall be the sole and final judge of such expediency. No member of the Committee shall be liable for any action or determination made in good faith. The determination, interpretations and other actions of the Committee pursuant to the provisions of the Plan shall be binding and conclusive for all purposes and on all persons.

3.2 Compliance with Section 162(m).

In accordance with this intent, the amount of income a Participant may receive from Options granted under the Plan shall be based solely on an increase in the value of the Stock after the date of the grant of the Option, or such other bases as may be permitted by applicable law. The Committee is authorized to take such additional action, if any, that may be required to ensure that the Plan satisfies the requirements of Section 162(m) and the regulations promulgated or revenue rulings published thereunder.

SECTION 4

STOCK SUBJECT TO THE PLAN

4.1 Number of Shares. Subject to Section 7.1 and to adjustment pursuant to
Section 4.3 hereof, two million five hundred thousand (2,500,000) shares of Stock are authorized for issuance under the Plan in accordance with the provisions of the Plan and subject to such restrictions or other provisions as the Committee may from time to time deem necessary. This authorization may be increased from time to time by approval of the Board and the stockholders of the Company if, on the advice of counsel for the Company, such stockholder approval is required. Shares of Stock which may be issued upon exercise of Options shall be applied to reduce the maximum number of shares of Stock remaining available for use under the Plan. The Company shall at all times during the term of the Plan and while any Options are outstanding retain as authorized and

4

unissued Stock, or as Stock in the Company's treasury, at least the number of shares from time to time required under the provisions of the Plan, or otherwise assure itself of its ability to perform its obligations hereunder.

4.2 Other Shares of Stock. Any shares of Stock that are subject to an Option which expires, is forfeited, is cancelled, or for any reason is terminated unexercised, and any shares of Stock that for any other reason are not issued to a Participant or are forfeited shall automatically become available for use under the Plan.

4.3 Adjustments for Stock Split, Stock Dividend, etc. If the Company shall at any time increase or decrease the number of its outstanding shares of Stock or change in any way the rights and privileges of such shares by means of the payment of a Stock dividend or any other distribution upon such shares payable in Stock, or through a Stock split, subdivision, consolidation, combination, reclassification or recapitalization involving the Stock then in relation to the Stock that is affected by one or more of the above events, the numbers, rights and privileges of the following shall be, in each case, equitably and proportionally adjusted to take into account the occurrence of any of the above events, (i) the shares of Stock as to which Options may be granted under the Plan; (ii) the shares of Stock then included in each outstanding Option granted hereunder; and (iii) the Option Price for each outstanding Option granted hereunder.

4.4 Dividend Payable in Stock of Another Corporation, Etc. If the Company shall at any time pay or make any dividend or other distribution upon the Stock payable in securities or other property (except money or Stock), a proportionate part of such securities or other property shall be set aside and delivered to any Participant then holding an Option for the particular type of Stock for which the dividend or other distribution was made, upon exercise thereof. Prior to the time that any such securities or other property are delivered to a Participant in accordance with the foregoing, the Company shall be the owner of such securities or other property and shall have the right to vote the securities, receive any dividends payable on such securities, and in all other respects shall be treated as the owner. If securities or other property which have been set aside by the Company in accordance with this Section are not delivered to a Participant because an Option is not exercised, then such securities or other property shall remain the property of the Company and shall be dealt with by the Company as it shall determine in its sole discretion.

4.5 Other Changes in Stock. In the event there shall be any change, other than as specified in Sections 4.3 and 4.4 hereof, in the number or kind of outstanding shares of Stock or of any stock or other securities into which the Stock shall be changed or for which it shall have been exchanged, and if the

5

Committee shall in its discretion determine that such change equitably requires an adjustment in the number or kind of shares subject to outstanding Options or which have been reserved for issuance pursuant to the Plan but are not then subject to an Option, then such adjustments shall be made by the Committee and shall be effective for all purposes of the Plan and on each outstanding Option that involves the particular type of stock for which a change was effected.

4.6 Rights to Subscribe. If the Company shall at any time grant to the holders of its Stock rights to subscribe pro rata for additional shares thereof or for any other securities of the Company or of any other corporation, there shall be reserved with respect to the shares then under Option to any Participant of the particular class of Stock involved the Stock or other securities which the Participant would have been entitled to subscribe for if immediately prior to such grant the Participant had exercised his entire Option. If, upon exercise of any such Option, the Participant subscribes for the additional shares or other securities, the aggregate Option Price shall be increased by the amount of the price that is payable by the Participant for such additional shares or other securities.

4.7 General Adjustment Rules. No adjustment or substitution provided for in this
Section 4 shall require the Company to sell a fractional share of Stock under any Option, or otherwise issue a fractional share of Stock, and the total substitution or adjustment with respect to each Option shall be limited by deleting any fractional share. In the case of any such substitution or adjustment, the aggregate Option Price for the shares of Stock then subject to the Option shall remain unchanged but the Option Price per share under each such Option shall be equitably adjusted by the Committee to reflect the greater or lesser number of shares of Stock or other securities into which the Stock subject to the Option may have been changed.

4.8 Determination by the Committee, Etc. Adjustments under this Section 4 shall be made by the Committee, whose determinations with regard thereto shall be final and binding upon all parties.

SECTION 5

REORGANIZATION OR LIQUIDATION

In the event that the Company is merged or consolidated with another corporation and the Company is not the surviving corporation, or if all or substantially all of the assets or more than 20 percent of the outstanding voting stock of the Company is acquired by any other corporation, business entity or person, or in case of a reorganization (other than a reorganization under the United States

6

Bankruptcy Code) or liquidation of the Company, and if the provisions of Section 8 hereof do not apply, the Committee, or the board of directors of any corporation assuming the obligations of the Company, shall, as to the Plan and outstanding Options either (i) make appropriate provision for the adoption and continuation of the Plan by the acquiring or successor corporation and for the protection of any such outstanding Options by the substitution on an equitable basis of appropriate stock of the Company or of the merged, consolidated or otherwise reorganized corporation which will be issuable with respect to the Stock, provided that no additional benefits shall be conferred upon the Participants holding such Options as a result of such substitution, and the excess of the aggregate Fair Market Value of the shares subject to the Options immediately after such substitution over the aggregate Option Price thereof is not more than the excess of the aggregate Fair Market Value of the shares subject to such Options immediately before such substitution over the aggregate Option Price thereof, or (ii) upon written notice to the Participants, provide that all unexercised Options shall be exercised within a specified number of days of the date of such notice or such Options will be terminated. In the latter event, the Committee shall accelerate the vesting dates of outstanding Options so that all Options become fully vested and exercisable prior to any such event.

SECTION 6

PARTICIPATION

Participants in the Plan shall be those Eligible Employees who, in the judgment of the Committee, are performing, or during the term of their incentive arrangement will perform, vital services in the management, operation and development of the Company or an Affiliated Corporation, and significantly contribute, or are expected to significantly contribute, to the achievement of the Company's long-term corporate economic objectives. Participants may be granted from time to time one or more Options; provided, however, that the grant of each such Option shall be separately approved by the Committee, and receipt of one such Option shall not result in automatic receipt of any other Option. Upon determination by the Committee that an Option is to be granted to a Participant, written notice shall be given to such person, specifying the terms, conditions, rights and duties related thereto. Each Participant shall, if required by the Committee, enter into an agreement with the Company, in such form as the Committee shall determine and which is consistent with the provisions of the Plan, specifying such terms, conditions, rights and duties. Options shall be deemed to be granted as of the date specified in the grant resolution of the Committee, which date shall be the date of any related agreement with the Participant. In the event of any inconsistency between the provisions of the Plan and any such agreement entered into hereunder, the provisions of the Plan shall govern.

7

SECTION 7

STOCK OPTIONS

7.1 Grant of Stock Options. Coincident with or following designation for participation in the Plan, an Eligible Employee may be granted one or more Options. Grants of Options under the Plan shall be made by the Committee. In no event shall the exercise of one Option affect the right to exercise any other Option or affect the number of shares of Stock for which any other Option may be exercised, except as provided in subsection 7.2(j) hereof. During the life of the Plan, no Eligible Employee may be granted Options which in the aggregate pertain to in excess of 25 percent of the total shares of Stock authorized under the Plan.

7.2 Stock Option Agreements. Each Option granted under the Plan shall be evidenced by a written stock option agreement which shall be entered into by the Company and the Participant to whom the Option is granted (the "Stock Option Agreement"), and which shall contain the following terms and conditions, as well as such other terms and conditions, not inconsistent therewith, as the Committee may consider appropriate in each case.

(a) Number of Shares. Each Stock Option Agreement shall state that it covers a specified number of shares of Stock, as determined by the Committee.

(b) Price. The price at which each share of Stock covered by an Option may be purchased shall be determined in each case by the Committee and set forth in the Stock Option Agreement, but in no event shall the price be less than the Fair Market Value of the Stock on the date the Option is granted.

(c) Duration of Options; Employment Required For Exercise. Each Stock Option Agreement shall state the period of time, determined by the Committee, within which the Option may be exercised by the Participant (the "Option Period"). The Option Period must end, in all cases, not more than ten years from the date an Option is granted. Except as otherwise provided in Sections 5 and 8 and subsection 7.2(d)(iv) hereof, each Option granted under the Plan shall become exercisable in increments such that 25 percent of the Option will become exercisable on each of the four subsequent one-year anniversaries of the date the Option is granted, but each such additional 25-percent increment shall become exercisable only if the Participant has been continuously employed by the Company from the date the Option is granted through the date on which each such additional 25-percent increment becomes exercisable.

8

(d) Termination of Employment, Death, Disability, Etc. Each Stock Option Agreement shall provide as follows with respect to the exercise of the Option upon termination of the employment or the death of the Participant:

(i) If the employment of the Participant by the Company is terminated within the Option Period for cause, as determined by the Company, the Option shall thereafter be void for all purposes. As used in this subsection 7.2(d), "cause" shall mean a gross violation, as determined by the Company, of the Company's established policies and procedures, provided that the effect of this subsection 7.2(d) shall be limited to determining the consequences of a termination and that nothing in this subsection 7.2(d) shall restrict or otherwise interfere with the Company's discretion with respect to the termination of any employee.

(ii) If the Participant retires from employment by the Company on or after attaining age 60, the Option may be exercised by the Participant within 36 months following his or her retirement (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such 36-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of the Participant's retirement.

(iii) If the Participant becomes disabled (as determined pursuant to the Company's Long-Term Disability Plan or any successor plan), during the Option Period while still employed, or within the three-month period referred to in (v) below, or within the 36-month period referred to in (ii) above, the Option may be exercised by the Participant or by his or her guardian or legal representative, within twelve months following the Participant's disability, or within the 36-month period referred to in (ii) above if applicable and if longer (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such twelve-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares of Stock as to which the Option had become exercisable on or before the date of the Participant's disability.

(iv) In the event of the Participant's death while still employed by the Company, each Option of the deceased Participant may be exercised by those entitled to do so under the Participant's will or under the laws of descent and distribution within twelve months following the Participant's death (provided that in any event such exercise must occur within the Option Period), but not thereafter, as to all shares of Stock which are subject to such Option, including each 25-percent

9

increment of the Option, if any, which has not yet become exercisable at the time of the Participant's death. In the event of the Participant's death within the 36-month period referred to in (ii) above or within the twelve-month period referred to in (iii) above, each Option of the deceased Participant that is exercisable at the time of death may be exercised by those entitled to do so under the Participant's will or under the laws of descent and distribution within twelve months following the Participant's death or within the 36-month period referred to in (ii) above, if applicable and if longer (provided that in any event such exercise must occur within the Option Period). The provisions of this paragraph (iv) of subsection 7.2(d) shall be applicable to each Stock Option Agreement as if set forth therein word for word. Each Stock Option Agreement executed by the Company prior to the adoption of this provision shall be deemed amended to include the provisions of this paragraph and all Options granted pursuant to such Stock Option Agreements shall be exercisable as provided herein.

(v) If the employment of the Participant by the Company is terminated (which for this purpose means that the Participant is no longer employed by the Company or by an Affiliated Corporation) within the Option Period for any reason other than cause, the Participant's retirement on or after attaining age 60, or the Participant's disability or death, the Option may be exercised by the Participant within three months following the date of such termination (provided that such exercise must occur within the Option Period), but not thereafter. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of termination of the Participant's employment.

(e) Transferability. Each Stock Option Agreement shall provide that the Option granted therein is not transferable by the Participant except by will or pursuant to the laws of descent and distribution, and that such Option is exercisable during the Participant's lifetime only by him or her, or in the event of the Participant's disability or incapacity, by his or her guardian or legal representative.

(f) Agreement to Continue in Employment. Each Stock Option Agreement shall contain the Participant's agreement to remain in the employment of the Company, at the pleasure of the Company, for a continuous period of at least one year after the date of such Stock Option Agreement, at the salary rate in effect on the date of such agreement or at such changed rate as may be fixed, from time to time, by the Company.

10

(g) Exercise, Payments, Etc.

(i) Each Stock Option Agreement shall provide that the method for exercising the Option granted therein shall be by delivery to the Office of the Secretary of the Company or to the Administrative Agent of written notice specifying the number of shares of Stock with respect to which such Option is exercised and payment to the Company of the aggregate Option Price. Such notice shall be in a form satisfactory to the Committee and shall specify the particular Options (or portions thereof) which are being exercised and the number of shares of Stock with respect to which the Options are being exercised. The exercise of the Option shall be deemed effective on the date such notice is received by the Office of the Secretary or by the Administrative Agent and payment is made to the Company of the aggregate Option Price (the "Exercise Date"); however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) below, the Exercise Date shall be deemed to be the date of such sale. If requested by the Company, such notice shall contain the Participant's representation that he or she is purchasing the Stock for investment purposes only and his or her agreement not to sell any Stock so purchased in any manner that is in violation of the Securities Act of 1933, as amended, or any applicable state law, and such restriction, or notice thereof, shall be placed on the certificates representing the Stock so purchased. The purchase of such Stock shall take place upon delivery of such notice to the Office of the Secretary or to the Administrative Agent, at which time the aggregate Option Price shall be paid in full to the Company by any of the methods or any combination of the methods set forth in 7.2(g)(iii) below.

(ii) Except as referenced below in connection with the Deferred Delivery Plan, the shares of Stock to which the Participant is entitled as a result of the exercise of the Option shall be issued by the Company and (A) delivered by electronic means to an account designated by the Participant, or (B) delivered to the Participant in the form of a properly executed certificate or certificates representing such shares of Stock. If shares of Stock and/or Depositary Shares are used to pay all or part of the aggregate Option Price, the Company shall issue and deliver to the Participant the additional shares of Stock, in excess of the aggregate Option Price or portion thereof paid using shares of Stock or Depositary Shares, to which the Participant is entitled as a result of the Option exercise. If the Participant exercising an Option (x) is eligible for participation in the Deferred Delivery Plan, (y) pays the aggregate Option Price pursuant to 7.2(g)(iii)(A), (B), (C), (D) or (E) below, and (z) has made an irrevocable election at least six months prior to the Exercise Date as required under the Deferred Delivery Plan, the income resulting from the Option exercise shall be deferred into the Participant's Deferred Delivery Plan account and no additional shares of Stock shall be delivered to the Participant.

11

(iii) the aggregate Option Price shall be paid by any of the following methods or any combination of the following methods:

(A) in cash, including the wire transfer of funds in U.S. dollars to one of the Company's bank accounts located in the United States, with such bank account to be designated from time to time by the Company;

(B) by personal, certified or cashier's check payable in U.S. dollars to the order of the Company;

(C) by delivery to the Company or the Administrative Agent of certificates representing a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, properly endorsed for transfer to the Company; provided that the shares of Stock used for this purpose must have been owned by the Participant for a period of at least six months;

(D) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the shares of Stock and/or Depositary Shares used for this purpose have been owned by the Participant for a period of at least six months;

(E) if the income resulting from the Option Exercise is to be deferred into the Participant's Deferred Delivery Plan account, by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of vested Stock Units held in the Participant's Deferred Delivery Plan account, the equivalent aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the Stock Units used for this purpose were vested as of the Exercise Date; or

(F) by delivery to the Company or the Administrative Agent of a properly executed notice of exercise together with irrevocable instructions to a broker to promptly deliver to the Company, by wire transfer or check as noted in (A) and (B) above, the amount of the proceeds of the sale of all or a portion of the Stock or of a loan from the broker to the Participant necessary to pay the aggregate Option Price.

12

(iv) For purposes of the Plan, the income resulting from an Option exercise shall be based on the Fair Market Value of the Stock for the Exercise Date; however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) hereof, the Fair Market Value shall be deemed to be the per share sale price and the Exercise Date shall be deemed to be the date of such sale.

(h) Date of Grant. An Option shall be considered as having been granted on the date specified in the grant resolution of the Committee.

(i) Tax Withholding. Each Stock Option Agreement shall provide that, upon exercise of the Option, the Participant shall make appropriate arrangements with the Company to provide for the amount of tax withholding required by Sections 3102 and 3402 or any successor section(s) of the Internal Revenue Code and applicable state and local income tax laws, including payment of such taxes in cash, by check, or as provided in Section 13.2 hereof.

(j) Adjustment of Options. Subject to the provisions of Sections 4, 5, 7, 8 and 12 hereof, the Committee may make any adjustment in the number of shares of Stock covered by, or the terms of an outstanding Option and a subsequent granting of an Option, by amendment or by substitution for an outstanding Option; however, except as provided in Sections 4, 5, 8 and 12 hereof, the Committee may not adjust the Option Price of any outstanding Option. Such amendment or substitution may result in terms and conditions (including the number of shares of Stock covered, vesting schedule or Option Period) that differ from the terms and conditions of the original Option. The Committee may not, however, adversely affect the rights of any Participant to previously granted Options without the consent of such Participant. If such action is effected by amendment, the effective date of such amendment will be the date of grant of the original Option.

7.3 Stockholder Privileges. No Participant shall have any rights as a stockholder with respect to any shares of Stock covered by an Option until the Participant becomes the holder of record of such Stock. Except as provided in
Section 4 hereof, no adjustments shall be made for dividends or other distributions or other rights as to which there is a record date preceding the date on which such Participant becomes the holder of record of such Stock.

SECTION 8

CHANGE OF CONTROL

8.1 In General. In the event of the occurrence of a change of control of the Company as defined in Section 8.3 hereof, all outstanding Options shall become

13

automatically vested, without further action by the Committee or the Board, so as to make all such Options fully vested and exercisable as of the date of such change of control.

8.2 Limitation on Payments. If the provisions of this Section 8 would result in the receipt by any Participant of a payment within the meaning of Section 280G or any successor section(s) of the Internal Revenue Code, and the regulations promulgated thereunder, and if the receipt of such payment by any Participant would, in the opinion of independent tax counsel of recognized standing selected by the Company, result in the payment by such Participant of any excise tax provided for in Sections 280G and 4999 or any successor section(s) of the Internal Revenue Code, then the amount of such payment shall be reduced to the extent required, in the opinion of independent tax counsel, to prevent the imposition of such excise tax; provided, however, that the Committee, in its sole discretion, may authorize the payment of all or any portion of the amount of such reduction to the Participant.

8.3 Definition. For purposes of the Plan, a "change of control" shall mean any of the events specified in the Company's Income Continuance Plan or any successor plan which constitute a change of control within the meaning of such plan.

SECTION 9

RIGHTS OF EMPLOYEES, PARTICIPANTS

9.1 Employment. Nothing contained in the Plan or in any Option granted under the Plan shall confer upon any Participant any right with respect to the continuation of his or her employment by the Company or any Affiliated Corporation, or interfere in any way with the right of the Company or any Affiliated Corporation, subject to the terms of any separate employment agreement to the contrary, at any time to terminate such employment or to increase or decrease the level of the Participant's compensation from the level in existence at the time of the grant of an Option. Whether an authorized leave of absence, or absence in military or government service, shall constitute a termination of employment shall be determined by the Committee at the time.

9.2 Nontransferability. No right or interest of any Participant in an Option granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Participant, either voluntarily or involuntarily, or subjected to any lien, directly or indirectly, by operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy. In the event of a Participant's death, a Participant's rights and interests in Options shall, to the

14

extent provided in Section 7 hereof, be transferable by testamentary will or the laws of descent and distribution, and payment of any amounts due under the Plan shall be made to, and exercise of any Options may be made by, the Participant's legal representatives, heirs or legatees. If, in the opinion of the Committee, a person entitled to payments or to exercise rights with respect to the Plan is disabled from caring for his or her affairs because of mental condition, physical condition or age, payment due such person may be made to, and such rights shall be exercised by, such person's guardian, conservator or other legal personal representative upon furnishing the Committee with evidence of such status satisfactory to the Committee.

SECTION 10

GENERAL RESTRICTIONS

10.1 Investment Representations. The Company may require a Participant, as a condition of exercising an Option, to give written assurances in substance and form satisfactory to the Company and its counsel to the effect that such person is acquiring the Stock subject to the Option for his own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with federal and applicable state securities laws.

10.2 Compliance with Securities Laws. Each Option shall be subject to the requirement that, if at any time counsel to the Company shall determine that the listing, registration or qualification of the shares of Stock subject to such Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, is necessary as a condition of, or in connection with, the issuance or purchase of shares of Stock thereunder, such Option may not be accepted or exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained on conditions acceptable to the Committee. Nothing herein shall be deemed to require the Company to apply for or to obtain such listing, registration, qualification, consent or approval.

SECTION 11

OTHER EMPLOYEE BENEFITS

The amount of any income deemed to be received by a Participant as a result of an Option exercise shall not constitute "earnings" or "compensation" with respect to which any other employee benefits of such Participant are determined

15

including, without limitation benefits under any pension, profit sharing, life insurance or salary continuation plan.

SECTION 12

PLAN AMENDMENT, MODIFICATION AND TERMINATION

The Board may at any time terminate, and from time to time may amend or modify the Plan provided, however, that no amendment or modification may become effective without approval of the amendment or modification by the Company's stockholders if stockholder approval is required to enable the Plan to satisfy any applicable statutory or regulatory requirements unless the Company, on the advice of counsel, determines that stockholder approval is otherwise necessary or desirable.

No amendment, modification or termination of the Plan shall in any manner adversely affect any Option theretofore granted under the Plan, without the consent of the Participant holding such Option.

The Committee shall have the authority to adopt such modifications, procedures and subplans as may be necessary or desirable to comply with the provisions of the laws (including, but not limited to, tax laws and regulations) of countries other than the United States in which the Company may operate, so as to assure the viability of the benefits of the Plan to Participants employed in such countries.

SECTION 13

WITHHOLDING

13.1 Withholding Requirement. The Company's obligations to deliver shares of Stock upon the exercise of an Option, or to defer income resulting from an Option exercise into the Deferred Delivery Plan, shall be subject to the Participant's satisfaction of all applicable federal, state and local income and other tax withholding requirements.

13.2 Satisfaction of Required Withholding. At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay all such amounts of required tax withholding, or any part thereof:

(b) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required to be withheld, provided that such shares of Stock and/or Depositary Shares have been owned by the Participant for a period of at least six months;

(c) if the income resulting from the Option exercise is to be deferred into the Participant's Deferred Delivery Plan account, by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of vested Stock Units held in the Participant's Deferred Delivery Plan account, the equivalent aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required to be withheld, provided that such Stock Units were vested as of the Exercise Date; or

(d) by the Company or the Administrative Agent withholding from the shares of Stock otherwise issuable to the Participant upon exercise of the Option, a number of shares of Stock, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required to be withheld. Any such elections by Participants to have shares of Stock withheld for this purpose will be subject to the following restrictions:

(i) all elections shall be made on or prior to the Exercise Date; and

(ii) all elections shall be irrevocable.

13.3 Excess Withholding. At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay additional or excess amounts of tax withholding, beyond the required amounts and up to the Participant's marginal tax rate:

(a) by delivery to the Company or the Administrative Agent of a number of Shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than such excess withholding amount, provided that such shares of Stock have been owned by the Participant for a period of at least six months; or

(b) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of

17

which (as of the Exercise Date) is not greater than such excess withholding amount, provided that such shares of Stock and/or Depositary Shares have been owned by the Participant for a period of at least six months.

13.4 Section 16 Requirements. If the Participant is an officer or director of the Company within the meaning of Section 16 or any successor section(s) of the 1934 Act ("Section 16"), the Participant must satisfy the requirements of such
Section 16 and any applicable rules and regulations thereunder with respect to the use of shares of Stock, Depositary Shares and/or Stock Units to satisfy such tax withholding obligation.

If a Participant is an officer or director of the Company within the meaning of Section 16, Options granted hereunder shall be subject to all conditions required under Rule 16b-3, or any successor rule(s) promulgated under the 1934 Act, to qualify the Option for any exception from the provisions of Section 16 available under such Rule. Such conditions are hereby incorporated herein by reference and shall be set forth in the Stock Option Agreement with the Participant which describes the Option.

14.3 Governing Law. The Plan and all Stock Option Agreements hereunder shall be construed in accordance with and governed by the laws of the State of Texas.

The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan, or in any agreement entered into hereunder, in the manner and to the extent it shall deem expedient and it shall be the sole and final judge of such expediency. No member of the Committee shall be liable for any action or determination made in good faith. The determination, interpretations and other actions of the Committee pursuant to the provisions of the Plan shall be binding and conclusive for all purposes and on all persons.

SECTION 4

STOCK SUBJECT TO THE PLAN

4.1 Number of Shares. Subject to Sections 7.1 and 7.4 hereof and to adjustment pursuant to Section 4.3 hereof, one million five hundred thousand (1,500,000) shares of Stock are authorized for issuance under the Plan in accordance with the provisions of the Plan and subject to such restrictions or other provisions as the Committee may from time to time deem necessary. This authorization may be increased from time to time by approval of the Board and the stockholders of the Company if, on the advice of counsel for the Company, such stockholder approval is required. Shares of Stock which may be issued upon exercise of Options shall be applied to reduce the maximum number of shares of Stock remaining available for use under the Plan. The Company shall at all times during the term of the Plan and while any Options are outstanding retain as authorized and unissued Stock, or as Stock in the Company's treasury, at least the number of shares from time to time required under the provisions of the Plan, or otherwise assure itself of its ability to perform its obligations hereunder.

4.2 Other Shares of Stock. Any shares of Stock that are subject to an Option which expires, is forfeited, is cancelled, or for any reason is terminated unexercised, and any shares of Stock that for any other reason are not issued to a Participant or are forfeited shall automatically become available for use under the Plan.

4

4.3 Adjustments for Stock Split, Stock Dividend, etc. If the Company shall at any time increase or decrease the number of its outstanding shares of Stock or change in any way the rights and privileges of such shares by means of the payment of a Stock dividend or any other distribution upon such shares payable in Stock, or through a Stock split, subdivision, consolidation, combination, reclassification or recapitalization involving the Stock then in relation to the Stock that is affected by one or more of the above events, the numbers, rights and privileges of the following shall be, in each case, equitably and proportionally adjusted to take into account the occurrence of any of the above events, (i) the shares of Stock as to which Options may be granted under the Plan; (ii) the shares of Stock then included in each outstanding Option granted hereunder; and (iii) the Option Price for each outstanding Option granted hereunder.

4.4 Dividend Payable in Stock of Another Corporation, Etc. If the Company shall at any time pay or make any dividend or other distribution upon the Stock payable in securities or other property (except money or Stock), a proportionate part of such securities or other property shall be set aside and delivered to any Participant then holding an Option for the particular type of Stock for which the dividend or other distribution was made, upon exercise thereof. Prior to the time that any such securities or other property are delivered to a Participant in accordance with the foregoing, the Company shall be the owner of such securities or other property and shall have the right to vote the securities, receive any dividends payable on such securities, and in all other respects shall be treated as the owner. If securities or other property which have been set aside by the Company in accordance with this Section are not delivered to a Participant because an Option is not exercised, then such securities or other property shall remain the property of the Company and shall be dealt with by the Company as it shall determine in its sole discretion.

4.5 Other Changes in Stock. In the event there shall be any change, other than as specified in Sections 4.3 and 4.4 hereof, in the number or kind of outstanding shares of Stock or of any stock or other securities into which the Stock shall be changed or for which it shall have been exchanged, and if the Committee shall in its discretion determine that such change equitably requires an adjustment in the number or kind of shares subject to outstanding Options or which have been reserved for issuance pursuant to the Plan but are not then subject to an Option, then such adjustments shall be made by the Committee and shall be effective for all purposes of the Plan and on each outstanding Option that involves the particular type of stock for which a change was effected.

5

4.6 Rights to Subscribe. If the Company shall at any time grant to the holders of its Stock rights to subscribe pro rata for additional shares thereof or for any other securities of the Company or of any other corporation, there shall be reserved with respect to the shares then under Option to any Participant of the particular class of Stock involved the Stock or other securities which the Participant would have been entitled to subscribe for if immediately prior to such grant the Participant had exercised his entire Option. If, upon exercise of any such Option, the Participant subscribes for the additional shares or other securities, the aggregate Option Price shall be increased by the amount of the price that is payable by the Participant for such additional shares or other securities.

4.7 General Adjustment Rules. No adjustment or substitution provided for in this
Section 4 shall require the Company to sell a fractional share of Stock under any Option, or otherwise issue a fractional share of Stock, and the total substitution or adjustment with respect to each Option shall be limited by deleting any fractional share. In the case of any such substitution or adjustment, the aggregate Option Price for the shares of Stock then subject to the Option shall remain unchanged but the Option Price per share under each such Option shall be equitably adjusted by the Committee to reflect the greater or lesser number of shares of Stock or other securities into which the Stock subject to the Option may have been changed.

4.8 Determination by the Committee, Etc. Adjustments under this Section 4 shall be made by the Committee, whose determinations with regard thereto shall be final and binding upon all parties.

SECTION 5

REORGANIZATION OR LIQUIDATION

In the event that the Company is merged or consolidated with another corporation and the Company is not the surviving corporation, or if all or substantially all of the assets or more than 20 percent of the outstanding voting stock of the Company is acquired by any other corporation, business entity or person, or in case of a reorganization (other than a reorganization under the United States Bankruptcy Code) or liquidation of the Company, and if the provisions of Section 8 hereof do not apply, the Committee, or the board of directors of any corporation assuming the obligations of the Company, shall, as to the Plan and outstanding Options either (i) make appropriate provision for the adoption and continuation of the Plan by the acquiring or successor corporation and for the protection of any

6

such outstanding Options by the substitution on an equitable basis of appropriate stock of the Company or of the merged, consolidated or otherwise reorganized corporation which will be issuable with respect to the Stock, provided that no additional benefits shall be conferred upon the Participants holding such Options as a result of such substitution, and the excess of the aggregate Fair Market Value of the shares subject to the Options immediately after such substitution over the aggregate Option Price thereof is not more than the excess of the aggregate Fair Market Value of the shares subject to such Options immediately before such substitution over the aggregate Option Price thereof, or (ii) upon written notice to the Participants, provide that all unexercised Options shall be exercised within a specified number of days of the date of such notice or such Options will be terminated. In the latter event, the Committee shall accelerate the vesting dates of outstanding Options so that all Options become fully vested and exercisable prior to any such event.

SECTION 6

PARTICIPATION

Participants in the Plan shall be those Eligible Employees who, in the judgment of the Committee, are performing, or during the term of their incentive arrangement will perform, vital services in the management, operation and development of the Company or an Affiliated Corporation, and significantly contribute, or are expected to significantly contribute, to the achievement of the Company's long-term corporate economic objectives. Participants may be granted from time to time one or more Options; provided, however, that the grant of each such Option shall be separately approved by the Committee, and receipt of one such Option shall not result in automatic receipt of any other Option. Upon determination by the Committee that an Option is to be granted to a Participant, written notice shall be given to such person, specifying the terms, conditions, rights and duties related thereto. Each Participant shall, if required by the Committee, enter into an agreement with the Company, in such form as the Committee shall determine and which is consistent with the provisions of the Plan, specifying such terms, conditions, rights and duties. Options shall be deemed to be granted as of the date specified in the grant resolution of the Committee, which date shall be the date of any related agreement with the Participant. In the event of any inconsistency between the provisions of the Plan and any such agreement entered into hereunder, the provisions of the Plan shall govern.

7

SECTION 7

STOCK OPTIONS

7.1 Grant of Stock Options. Coincident with or following designation for participation in the Plan, an Eligible Employee may be granted one or more Options. Grants of Options under the Plan shall be made by the Committee. In no event shall the exercise of one Option affect the right to exercise any other Option or affect the number of shares of Stock for which any other Option may be exercised, except as provided in subsection 7.2(j) hereof. During the duration of the Plan, no Eligible Employee may be granted Options which in the aggregate cover in excess of 25 percent of the total shares of Stock authorized under the Plan.

7.2 Stock Option Agreements. Each Option granted under the Plan shall be evidenced by a written stock option agreement which shall be entered into by the Company and the Participant to whom the Option is granted (the "Stock Option Agreement"), and which shall contain the following terms and conditions, as well as such other terms and conditions, not inconsistent therewith, as the Committee may consider appropriate in each case:

(a) Number of Shares. Each Stock Option Agreement shall state that it covers a specified number of shares of Stock, as determined by the Committee.

(b) Price. The price at which each share of Stock covered by an Option may be purchased shall be determined in each case by the Committee and set forth in the Stock Option Agreement, but in no event shall the price be less than the Fair Market Value of the Stock on the date the Option is granted.

(c) Duration of Options; Employment Required For Exercise. Each Stock Option Agreement shall state the period of time, determined by the Committee, within which the Option may be exercised by the Participant (the "Option Period"). The Option Period must end, in all cases, not more than ten years from the date an Option is granted. Except as otherwise provided in Sections 5 and 8 and subsections 7.2(d)(iv) and 7.4(a) hereof, each Option granted under the Plan shall become exercisable in increments such that 25 percent of the Option becomes exercisable on each of the four subsequent one-year anniversaries of the date the Option is granted, provided that each such additional 25-percent increment shall become exercisable only if the Participant has been continuously employed by the Company from the date the Option is granted through the date on which each such additional 25-percent increment becomes exercisable.

8

(d) Termination of Employment, Death, Disability, Etc. Each Stock Option Agreement shall provide as follows with respect to the exercise of the Option upon termination of the employment or the death of the Participant:

(i) If the employment of the Participant by the Company is terminated within the Option Period for cause, as determined by the Company, the Option shall thereafter be void for all purposes. As used in this subsection 7.2(d), "cause" shall mean a gross violation, as determined by the Company, of the Company's established policies and procedures, provided that the effect of this subsection 7.2(d) shall be limited to determining the consequences of a termination and that nothing in this subsection 7.2(d) shall restrict or otherwise interfere with the Company's discretion with respect to the termination of any employee.

(ii) If the Participant retires from employment by the Company on or after attaining age 60, the Option may be exercised by the Participant within 36 months following his or her retirement (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such 36-month period, each Option may be exercised by those entitled to do so in the manner referred to in (iv) below. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of the Participant's retirement.

(iii) If the Participant becomes disabled (as determined pursuant to the Company's Long-Term Disability Plan or any successor plan), during the Option Period while still employed, or within the three-month period referred to in subsection 7.2(d)(v) below, or within the 36-month period referred to in subsection 7.2(d)(ii) above, the Option may be exercised by the Participant or by his or her guardian or legal representative, within twelve months following the Participant's disability, or within the 36-month period referred to in subsection 7.2(d)(ii) above if applicable and if longer (provided that such exercise must occur within the Option Period), but not thereafter. In the event of the Participant's death during such twelve-month period, each Option may be exercised by those entitled to do so in the manner referred to in subsection 7.2(d)(iv) below. In any such case, the Option may be exercised only as to the shares of Stock as to which the Option had become exercisable on or before the date of the Participant's disability.

(iv) In the event of the Participant's death while still employed by the Company, each Option of the deceased Participant may be exercised by those entitled to do so under the Participant's will or under the laws of descent and

9

distribution within twelve months following the Participant's death (provided that in any event such exercise must occur within the Option Period), but not thereafter, as to all shares of Stock which are subject to such Option, including each 25-percent increment of the Option, if any, which has not yet become exercisable at the time of the Participant's death. In the event of the Participant's death within the 36-month period referred to in subsection 7.2(d)(ii) above or within the twelve-month period referred to in subsection 7.2(d)(iii) above, each Option of the deceased Participant that is exercisable at the time of death may be exercised by those entitled to do so under the Participant's will or under the laws of descent and distribution within twelve months following the Participant's death or within the 36-month period referred to in subsection 7.2(d)(ii) above, if applicable and if longer (provided that in any event such exercise must occur within the Option Period). The provisions of this paragraph (iv) of subsection 7.2(d) shall be applicable to each Stock Option Agreement as if set forth therein word for word. Each Stock Option Agreement executed by the Company prior to the adoption of this provision shall be deemed amended to include the provisions of this paragraph and all Options granted pursuant to such Stock Option Agreements shall be exercisable as provided herein.

(v) If the employment of the Participant by the Company is terminated (which for this purpose means that the Participant is no longer employed by the Company or by an Affiliated Corporation) within the Option Period for any reason other than cause, the Participant's retirement on or after attaining age 60, or the Participant's disability or death, the Option may be exercised by the Participant within three months following the date of such termination (provided that such exercise must occur within the Option Period), but not thereafter. In any such case, the Option may be exercised only as to the shares as to which the Option had become exercisable on or before the date of termination of the Participant's employment.

(e) Transferability. Each Stock Option Agreement shall provide that the Option granted therein is not transferable by the Participant except by will or pursuant to the laws of descent and distribution, and that such Option is exercisable during the Participant's lifetime only by him or her, or in the event of the Participant's disability or incapacity, by his or her guardian or legal representative.

(f) Agreement to Continue in Employment. Each Stock Option Agreement shall contain the Participant's agreement to remain in the employment of the Company, at the pleasure of the Company, for a continuous period of at least one year after the date of such Stock Option Agreement, at the salary rate in

10

effect on the date of such agreement or at such changed rate as may be fixed, from time to time, by the Company.

(g) Exercise, Payments, Etc.

(i) Each Stock Option Agreement shall provide that the method for exercising the Option granted therein shall be by delivery to the Office of the Secretary of the Company or to the Administrative Agent of written notice specifying the number of shares of Stock with respect to which such Option is exercised and payment to the Company of the aggregate Option Price. Such notice shall be in a form satisfactory to the Committee and shall specify the particular Options (or portions thereof) which are being exercised and the number of shares of Stock with respect to which the Options are being exercised. The exercise of the Option shall be deemed effective on the date such notice is received by the Office of the Secretary or by the Administrative Agent and payment is made to the Company of the aggregate Option Price (the "Exercise Date"); however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) below, the Exercise Date shall be deemed to be the date of such sale. If requested by the Company, such notice shall contain the Participant's representation that he or she is purchasing the Stock for investment purposes only and his or her agreement not to sell any Stock so purchased in any manner that is in violation of the Securities Act of 1933, as amended, or any applicable state law, and such restriction, or notice thereof, shall be placed on the certificates representing the Stock so purchased. The purchase of such Stock shall take place upon delivery of such notice to the Office of the Secretary of the Company or to the Administrative Agent, at which time the aggregate Option Price shall be paid in full to the Company by any of the methods or any combination of the methods set forth in subsection 7.2(g)(iii) below.

(ii) Except as referenced below in connection with the Deferred Delivery Plan, the shares of Stock to which the Participant is entitled as a result of the exercise of the Option shall be issued by the Company and (A) delivered by electronic means to an account designated by the Participant, or (B) delivered to the Participant in the form of a properly executed certificate or certificates representing such shares of Stock. If shares of Stock and/or Depositary Shares are used to pay all or part of the aggregate Option Price, the Company shall issue and deliver to the Participant the additional shares of Stock, in excess of the aggregate Option Price or portion thereof paid using shares of Stock or Depositary Shares, to which the Participant is entitled as a result of the Option exercise. If the Participant exercising an Option (x) is eligible for participation in the Deferred Delivery Plan, (y) pays the aggregate Option Price pursuant to

11

subsection 7.2(g)(iii)(A), (B), (C), (D) or (E) below, and (z) has made an irrevocable election at least six months prior to the Exercise Date as required under the Deferred Delivery Plan, the income resulting from the Option exercise shall be deferred into the Participant's Deferred Delivery Plan account and no additional shares of Stock shall be delivered to the Participant.

(iii) the aggregate Option Price shall be paid by any of the following methods or any combination of the following methods:

(A) in cash, including the wire transfer of funds in U.S. dollars to one of the Company's bank accounts located in the United States, with such bank account to be designated from time to time by the Company;

(B) by personal, certified or cashier's check payable in U.S. dollars to the order of the Company;

(C) by delivery to the Company or the Administrative Agent of certificates representing a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, properly endorsed for transfer to the Company, provided that the shares of Stock used for this purpose must have been owned by the Participant for a period of at least six months;

(D) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the shares of Stock and/or Depositary Shares used for this purpose have been owned by the Participant for a period of at least six months;

(E) if the income resulting from the Option exercise is to be deferred into the Participant's Deferred Delivery Plan account, by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of vested Stock Units held in the Participant's Deferred Delivery Plan account, the equivalent aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the aggregate Option Price of the Option being exercised, provided that the Stock Units used for this purpose were vested as of the Exercise Date; or

12

(F) by delivery to the Company or the Administrative Agent of a properly executed notice of exercise together with irrevocable instructions to a broker to promptly deliver to the Company, by wire transfer or check as noted in subsection 7.2(g)(iii)(A) and (B) above, the amount of the proceeds of the sale of all or a portion of the Stock or of a loan from the broker to the Participant necessary to pay the aggregate Option Price.

(iv) For purposes of the Plan, the income resulting from an Option exercise shall be based on the Fair Market Value of the Stock for the Exercise Date; however, if payment of the aggregate Option Price is made pursuant to a sale of shares of Stock as contemplated by subsection 7.2(g)(iii)(F) hereof, the Fair Market Value shall be deemed to be the per share sale price and the Exercise Date shall be deemed to be the date of such sale.

(h) Date of Grant. An Option shall be considered as having been granted on the date specified in the grant resolution of the Committee.

(i) Tax Withholding. Each Stock Option Agreement shall provide that, upon exercise of the Option, the Participant shall make appropriate arrangements with the Company to provide for the amount of tax withholding required by Sections 3102 and 3402 or any successor section(s) of the Internal Revenue Code and applicable state and local income and other tax laws, including payment of such taxes in cash, by check, or as provided in Section 13.2 hereof.

(j) Adjustment of Options. Subject to the provisions of Sections 4, 5, 7, 8 and 12 hereof, the Committee may make any adjustment in the number of shares of Stock covered by, or the terms of an outstanding Option and a subsequent granting of an Option, by amendment or by substitution for an outstanding Option; however, except as provided in Sections 4, 5, 8 and 12 hereof, the Committee may not adjust the Option Price of any outstanding Option. Such amendment or substitution may result in terms and conditions (including the number of shares of Stock covered, vesting schedule or Option Period) that differ from the terms and conditions of the original Option. The Committee may not, however, adversely affect the rights of any Participant to previously granted Options without the consent of such Participant. If such action is effected by amendment, the effective date of such amendment will be the date of grant of the original Option.

7.3 Stockholder Privileges. No Participant shall have any rights as a stockholder with respect to any shares of Stock covered by an Option until the Participant becomes the holder of record of such Stock. Except as provided in
Section 4 hereof, no adjustments shall be made for dividends or other

13

distributions or other rights as to which there is a record date preceding the date on which such Participant becomes the holder of record of such Stock.

7.4 Reload Provisions.

(a) The Committee shall have the authority, but not an obligation, to include as a part of any Stock Option Agreement provisions under which the Participant shall be granted a further option (a "Reload Option") when the Participant exercises all or part of the Option represented by such Stock Option Agreement and pays all or part of the aggregate Option Price and/or required or excess tax withholding pursuant to subsections 7.2(g)(iii)(C), (D) or (E) and/or subsections 13.2(a), (b) or (c) and/or subsections 13.3(a) or (b) hereof. Any Option including such reload provisions shall become exercisable in increments such that 25 percent of the Option becomes exercisable on the dates six months, 12 months, 18 months and 24 months following the date the Option is granted, provided that each such additional 25-percent increment shall become exercisable only if the Participant has been continuously employed by the Company from the date the Option is granted through the date on which such additional 25-percent increment becomes exercisable.

(b) Any shares of Stock issued to a Participant as a result of an Option exercise which resulted in the grant of a Reload Option, may not be sold or otherwise disposed of until the term of the original Option has expired or the Participant is no longer employed by the Company or by an Affiliated Corporation. Any Stock Units acquired by a Participant as a result of the deferral of income (pursuant to subsection 7.2(g)(ii) hereof) in connection with an Option exercise which resulted in the grant of a Reload Option, may not be sold or otherwise disposed of until the shares of Stock relating to such Stock Units are distributed under the terms of the Deferred Delivery Plan.

(c) A Reload Option shall be granted, without further action of the Committee or the Participant, if one or more of the payment provisions referenced in subsection 7.4(a) above are used and if all of the following are satisfied as of the date of exercise of the underlying Option:

(i) the Participant has not previously been granted a Reload Option or there has been a period of more than six months since the Participant was last granted a Reload Option;

(ii) no shares of Stock have been sold or otherwise disposed of in breach of the provisions of subsection 7.4(b) above;

14

(iii) the Fair Market Value of the shares of Stock covered by the original Option being exercised is at least ten percent greater than the Option Price for such shares; and

(iv) there is a period of more than six months remaining in the term of the original Option.

(d) Each Reload Option:

(i) shall cover that certain number of shares of Stock equal to the shares or equivalent shares of Stock actually or constructively delivered to the Company as referenced in subsection 7.4(a) above;

(ii) shall be deemed to be granted as of the date on which the original Option is exercised and shall have an Option Price of 100 percent of Fair Market Value on such date;

(iii) shall become exercisable six months after the date of grant and shall have the same Expiration Date as the original Option; and

(iv) except as set forth in subsections 7.4(d)(i), (ii) and (iii) above, shall have the same terms and conditions as those of the original Option.

SECTION 8

CHANGE OF CONTROL

8.1 In General. In the event of the occurrence of a change of control of the Company, as defined in Section 8.3 hereof, all outstanding Options shall become automatically vested, without further action by the Committee or the Board, so as to make all such Options fully vested and exercisable as of the date of such change of control.

8.2 Limitation on Payments. If the provisions of this Section 8 would result in the receipt by any Participant of a payment within the meaning of Section 280G or any successor section(s) of the Internal Revenue Code, and the regulations promulgated thereunder, and if the receipt of such payment by any Participant would, in the opinion of independent tax counsel of recognized standing selected by the Company, result in the payment by such Participant of any excise tax provided for in Sections 280G and 4999 or any successor section(s) of the Internal Revenue Code, then the amount of such payment shall be reduced to the extent required, in the opinion of independent tax counsel, to prevent the

15

imposition of such excise tax; provided, however, that the Committee, in its sole discretion, may authorize the payment of all or any portion of the amount of such reduction to the Participant.

8.3 Definition. For purposes of the Plan, a "change of control" shall mean any of the events specified in the Company's Income Continuance Plan or any successor plan which constitute a change of control within the meaning of such plan.

SECTION 9

RIGHTS OF EMPLOYEES, PARTICIPANTS

9.1 Employment. Nothing contained in the Plan or in any Option granted under the Plan shall confer upon any Participant any right with respect to the continuation of his or her employment by the Company or any Affiliated Corporation, or interfere in any way with the right of the Company or any Affiliated Corporation, subject to the terms of any separate employment agreement to the contrary, at any time to terminate such employment or to increase or decrease the level of the Participant's compensation from the level in existence at the time of the grant of an Option. Whether an authorized leave of absence, or absence in military or government service, shall constitute a termination of employment shall be determined by the Committee at the time.

9.2 Nontransferability. No right or interest of any Participant in an Option granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Participant, either voluntarily or involuntarily, or subjected to any lien, directly or indirectly, by operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy. In the event of a Participant's death, a Participant's rights and interests in Options shall, to the extent provided in Section 7 hereof, be transferable by testamentary will or the laws of descent and distribution, and payment of any amounts due under the Plan shall be made to, and exercise of any Options may be made by, the Participant's legal representatives, heirs or legatees. If, in the opinion of the Committee, a person entitled to payments or to exercise rights with respect to the Plan is disabled from caring for his or her affairs because of mental condition, physical condition or age, payment due such person may be made to, and such rights shall be exercised by, such person's guardian, conservator or other legal personal representative upon furnishing the Committee with evidence of such status satisfactory to the Committee.

16

SECTION 10

GENERAL RESTRICTIONS

10.1 Investment Representations. The Company may require a Participant, as a condition of exercising an Option, to give written assurances in substance and form satisfactory to the Company and its counsel to the effect that such person is acquiring the Stock subject to the Option for his own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with federal and applicable state securities laws.

10.2 Compliance with Securities Laws. Each Option shall be subject to the requirement that, if at any time counsel to the Company shall determine that the listing, registration or qualification of the shares of Stock subject to such Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, is necessary as a condition of, or in connection with, the issuance or purchase of shares of Stock thereunder, such Option may not be accepted or exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained on conditions acceptable to the Committee. Nothing herein shall be deemed to require the Company to apply for or to obtain such listing, registration, qualification, consent or approval.

SECTION 11

OTHER EMPLOYEE BENEFITS

The amount of any income deemed to be received by a Participant as a result of an Option exercise shall not constitute "earnings" or "compensation" with respect to which any other employee benefits of such Participant are determined including, without limitation, benefits under any pension, profit sharing, life insurance or salary continuation plan.

17

SECTION 12

PLAN AMENDMENT, MODIFICATION AND TERMINATION

The Board may at any time terminate, and from time to time may amend or modify the Plan provided, however, that no amendment or modification may become effective without approval of the amendment or modification by the Company's stockholders if stockholder approval is required to enable the Plan to satisfy any applicable statutory or regulatory requirements unless the Company, on the advice of counsel, determines that stockholder approval is otherwise necessary or desirable.

No amendment, modification or termination of the Plan shall in any manner adversely affect any Option theretofore granted under the Plan, without the consent of the Participant holding such Option.

The Committee shall have the authority to adopt such modifications, procedures and subplans as may be necessary or desirable to comply with the provisions of the laws (including, but not limited to, tax laws and regulations) of countries other than the United States in which the Company may operate, so as to assure the viability of the benefits of the Plan to Participants employed in such countries.

SECTION 13

WITHHOLDING

13.1 Withholding Requirement. The Company's obligations to deliver shares of Stock upon the exercise of an Option, or to defer income resulting from an Option exercise into the Deferred Delivery Plan, shall be subject to the Participant's satisfaction of all applicable federal, state and local income and other tax withholding requirements.

13.2 Satisfaction of Required Withholding. At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay all such amounts of required tax withholding, or any part thereof:

(a) by the delivery to the Company or the Administrative Agent of a number of shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required

18

to be withheld, provided that such shares have been held by the Participant for a period of at least six months;

(b) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required to be withheld, provided that such shares of Stock and/or Depositary Shares have been owned by the Participant for a period of at least six months;

(c) if the income resulting from the Option exercise is to be deferred into the Participant's Deferred Delivery Plan account, by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of vested Stock Units held in the Participant's Deferred Delivery Plan account, the equivalent aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required to be withheld, provided that such Stock Units were vested as of the Exercise Date; or

(d) by the Company or the Administrative Agent withholding from the shares of Stock otherwise issuable to the Participant upon exercise of the Option, a number of shares of Stock, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than the amount required to be withheld. Any such elections by Participants to have shares of Stock withheld for this purpose will be subject to the following restrictions:

(i) all elections shall be made on or prior to the Exercise Date; and

(ii) all elections shall be irrevocable.

13.3 Excess Withholding. At the time the Committee grants an Option, it may, in its sole discretion, grant the Participant an election to pay additional or excess amounts of tax withholding, beyond the required amounts and up to the Participant's marginal tax rate:

(a) by delivery to the Company or the Administrative Agent of a number of Shares of Stock then owned by the Participant, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than such excess withholding amount, provided that such shares of Stock have been owned by the Participant for a period of at least six months; or

19

(b) by certification or attestation to the Company or the Administrative Agent of the Participant's ownership (as of the Exercise Date) of a number of shares of Stock and/or Depositary Shares, the aggregate Fair Market Value of which (as of the Exercise Date) is not greater than such excess withholding amount, provided that such shares of Stock and/or Depositary Shares have been owned by the Participant for a period of at least six months.

13.4 Section 16 Requirements. If the Participant is an officer or director of the Company within the meaning of Section 16 or any successor section(s) of the 1934 Act ("Section 16"), the Participant must satisfy the requirements of such
Section 16 and any applicable rules and regulations thereunder with respect to the use of shares of Stock, Depositary Shares and/or Stock Units to satisfy such tax withholding obligation.

SECTION 14

REQUIREMENTS OF LAW

14.1 Requirements of Law. The issuance of Stock and the payment of cash pursuant to the Plan shall be subject to all applicable laws, rules and regulations.

14.2 Federal Securities Laws Requirements. If a Participant is an officer or director of the Company within the meaning of Section 16, Options granted hereunder shall be subject to all conditions required under Rule 16b-3, or any successor rule(s) promulgated under the 1934 Act, to qualify the Option for any exception from the provisions of Section 16 available under such Rule. Such conditions are hereby incorporated herein by reference and shall be set forth in the Stock Option Agreement with the Participant which describes the Option.

14.3 Governing Law. The Plan and all Stock Option Agreements hereunder shall be construed in accordance with and governed by the laws of the State of Texas.

20

SECTION 15

DURATION OF THE PLAN

The Plan shall terminate at such time as may be determined by the Board, and no Option shall be granted after such termination. If not sooner terminated under the preceding sentence, the Plan shall fully cease and expire at midnight on February 10, 2005. Any Options outstanding at the time of the Plan termination shall continue to be exercisable in accordance with the Stock Option Agreement pertaining to each such Option.
