Employees' Investment Plan
Financial Statements and Additional Information
November 30, 1998 and 1997

                       Report of Independent Accountants



To the Participants, Investment Plan Committee
and Benefits Funds Committee of the Caterpillar Inc.
Employees' Investment Plan

In our opinion, the accompanying statements of net assets available for plan
benefits and the related statements of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
plan benefits of the Caterpillar Inc. Employees' Investment Plan (the Plan) at
November 30, 1998 and 1997, and the changes in net assets available for plan
benefits for the years ended November 30, 1998 and 1997, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Plan's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedules of assets
held for investment purposes and of reportable (5%) transactions are presented
for the purpose of additional analysis and are not a required part of the basic
financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974 (ERISA).  The fund
information in the statements of net assets available for plan benefits and the
statements of changes in net assets available for plan benefits is presented for
purposes of additional analysis rather than to present the net assets available
for plan benefits and changes in net assets available for plan benefits of each
fund.  These supplemental schedules and fund information are the responsibility
of the Plan's management.  The supplemental schedules and fund information have
been subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

The schedule of assets held for investment purposes that accompanies the Plan's
financial statements does not disclose the historical cost of certain plan
assets held by a Plan custodian.  Disclosure of this information is required by
ERISA.

NOTE 1 - PLAN DESCRIPTION:
- -------------------------

The following description of the Caterpillar Inc. Employees' Investment Plan
(the Plan) provides only general information. Employees should refer to the Plan
agreement for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution plan established by Caterpillar Inc. (the
Company) to enable eligible employees of the Company and its subsidiaries (the
employers) which adopt the Plan to accumulate funds.

Participation

Generally, employees of participating employer companies, other than those
employed under collective bargaining agreements, who meet certain age, service
and citizenship or residency requirements are eligible to participate in the
plan. Participation commences upon an eligible employee's filing of an
application with the Investment Plan Committee. Participating eligible employees
(the participants) may acquire ownership interests in the Company through
purchases of its common stock (Part 1). Additionally, the participants may elect
to defer a portion of their compensation until retirement under the Special
Investment Supplement of the Plan (Part 2).

Participant accounts

Accounts are maintained separately for Part 1 and Part 2 for each participant.
The participant's separate account under Part 1 is credited with the
participant's contribution, the employer's contribution and an allocation of
Plan earnings. The participant's account under Part 2 of the Plan is credited
with the participant's contribution as defined below and an allocation of Plan
earnings. Allocations of earnings are based on participant account balances, as
defined. The benefit to which a participant is entitled is the benefit that can
be provided from the participant's accounts.

Loan provisions

The Plan provides for participant loans against eligible participants' Part 2
separate account balances. Eligible employees obtain participant loans by filing
a loan application with the Company and receiving approval thereof. Loan amounts
are generally limited to the lesser of $50,000 or 50% of the individual
participant's account balance, within certain regulatory restrictions. Loan
repayment terms may range from 6 to 117 months depending on the type of loan and
bear interest at the prime interest rate plus 1% rounded to the nearest whole
percent. Repayments, including interest, are made through after-tax payroll
deductions and are credited to the individual participant's account balance.
Loan transactions are treated as a transfer to (from) the applicable investment
fund (from) to the Loan fund.

Contributions

 Part 1 -

Participant contributions are made through after-tax payroll deductions based on
a percentage (2%-6%) of total earnings as elected by the employee. Participants
with 25 or more years of service with the employers may contribute an additional
1%-4% of earnings.

                                      -6-
<PAGE>

Employer contributions are 50%, 66-2/3% or 80% of participant contributions (up
to 6% of earnings) based on the participant's years of service.

 Part 2 -

Participant contributions are made through a pretax compensation deferral as
elected by the participants and are contributed to the Plan by the employer.
During 1998, the compensation deferral was limited to (a) the greater of $6,000
or 4% of the participant's compensation (limited by the Internal Revenue Code to
$10,000 in 1998) for participants earning in excess of $80,000 or (b) $10,000
for participants earning less than $80,000.

During 1997, the compensation deferral was limited to (a) the greater of $5,000
or 4% of the participant's compensation (limited by the Internal Revenue Code to
$9,500 in 1997) for participants earning in excess of $75,000 or (b) $9,500 for
participants earning less than $75,000.

Investment programs

 Part 1 -

Employer contributions are invested entirely in Caterpillar Inc. common stock.
Participants may elect to have their contributions invested as follows: (1) 100%
in Caterpillar Inc. common stock or (2) 50% in Caterpillar Inc. common stock and
50% in a Collective Government Short-Term Investment Fund. The Collective
Government Short-Term Investment Fund is managed by The Northern Trust Company.

 Part 2 -

Participants may elect to have their contributions invested in any combination
of the funds shown on the accompanying statements of changes in net assets
available for plan benefits with fund information, including a self-directed
fund option which allows participants to invest in various other mutual funds
outside of the Preferred Group of Mutual Funds. Contributions to and withdrawals
from this self-directed fund occur through transfers to/from other elected
funds. State Street Bank serves as custodian for funds invested through this
self-directed fund option.

Interfund transfers

Transfers of assets between investment funds are recorded on a net basis in the
statement of changes in net assets available for plan benefits with fund
information.

Vesting and distribution provisions

 Part 1 -

Participants are fully vested at all times in Caterpillar Inc. common stock or
units of the Collective Government Short-Term Investment Fund purchased with
participant contributions.

Participants begin vesting in shares purchased with employer contributions
generally after the end of the second year of plan participation. Participants
generally vest at the rate of 33% per year, resulting in full vesting by
participants in employer contributions after five years of service with the
Company. Any amounts not vested at withdrawal which are forfeited will be
applied to reduce the amount of future employer contributions to the Plan.
Shares become fully vested upon retirement, permanent disability or death.


                                      -7-
<PAGE>

While an employee, a participant may elect to withdraw all participant purchased
shares of common stock, his share of the government short-term investment fund
and all earnings on participant contributions as provided by the Plan. Employer
contributions may also be withdrawn based on vested status as provided by the
Plan. Upon termination of employment, participants may elect (with spousal
consent, if applicable) to receive their shares by immediate distribution or a
deferred distribution. If termination is due to retirement or disability,
participants may elect (with spousal consent, if applicable) various annuity
payments.

 Part 2 -

Participants are fully vested in their participant contributions. Upon
termination of employment for any reason, including death, retirement or total
and permanent disability, or upon Plan termination, the balance or balances in
participants' accounts are distributable.

Administration

The Plan is administered by the Investment Plan Committee, which is responsible
for nonfinancial matters, and the Benefits Funds Committee, which is responsible
for financial aspects of the Plan. Caterpillar Inc. and the Benefit Funds
Committee have entered into trust agreements with The Northern Trust Company to
receive contributions, administer the assets of the Plan and distribute
withdrawals pursuant to the Plan.

Plan termination

In the event the Plan is terminated or partially terminated, each participant in
Part 1 shall also have a fully vested interest in the assets attributable to
employer contributions.

Federal income tax status

The Internal Revenue Service has determined and informed the Company by letter
dated March 8, 1990, that the Plan and related trust are designed in accordance
with applicable sections of the Internal Revenue Code (IRC). The Plan has been
amended subsequent to amendments covered by the determination letter; however,
the Plan administrator and the Plan's legal counsel believe that the Plan is
designed and is currently being operated in compliance with the applicable
requirements of the IRC.

NOTE 2 - SUMMARY OF SIGNIFICANT
- -------------------------------
         ACCOUNTING POLICIES:
         -------------------

Basis of accounting

The Plan's accounts are maintained on the accrual basis of accounting.

Investments

The Plan's investments are stated at fair value. The Caterpillar Inc. common
stock is valued at quoted market prices. The fair value of the Plan's investment
in the Collective Government Short-Term Investment Fund and the 401(k) Master
Trust (Note 4) is based upon the beginning of the year value of the Plan's
investment plus actual contributions, transfers and allocated investment income
less actual withdrawals. Shares of registered investment companies included in
the self-directed fund option are valued at quoted market prices which represent
the net asset value of shares held by the Plan at year end. Income from
investments is recorded as earned.

                                      -8-
<PAGE>

Contributions

Contributions to the Caterpillar Common Stock Fund under Part 1 of the Plan are
made directly to the trust and shares are immediately purchased by the trust on
the open market.

Administrative expenses

Administrative costs, including trustee fees and certain investment costs, are
paid by the Company.

Use of estimates in the preparation
of financial statements

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets, liabilities, income and benefit payments.
Actual results could differ from those estimates. The Company believes the
techniques and assumptions used in establishing these amounts are appropriate.

NOTE 3 - UNIT VALUES:
- --------------------

Part 2 of the Plan assigns units to participants directing investments to the
Caterpillar Common Stock Fund. The unit values assigned by the Plan reflect the
current values of the individual fund. Total units held (in thousands) by the
Plan and their respective unit values at each month end are as follows:

NOTE 4 - MASTER TRUST:
- ---------------------

Under a Master Trust agreement with The Northern Trust Company (the Trustee),
Part 2 of the Caterpillar Inc. Employees' Investment Plan (EIP 2), the Solar
Turbines Incorporated Savings and Investment Plan and the Caterpillar Inc. Tax
Deferred Savings Plan pool their investments in the Caterpillar Inc. 401(k)
Master Trust (the Master Trust) in exchange for a percentage of participation in
the Trust.

The Master Trust invests in the Preferred Group of Mutual Funds, registered
investment companies which are sponsored by Caterpillar Investment Management
Ltd. (CIML), a wholly-owned subsidiary of the Company. The options available to
the participants through the Preferred Group of Mutual Funds are comprised of
the following:

      Preferred Stable Principal Fund
      Preferred Short-Term Government Fund       Preferred Value Fund
      Preferred Growth Fund                      Preferred Fixed Income Fund
      Preferred Money Market Fund                Preferred International Fund
      Preferred Asset Allocation Fund            Preferred Small Cap Fund

                                      -9-
<PAGE>

CIML manages the Preferred Small Cap Fund and the Preferred Short-Term
Government Fund; however, during the period November 1, 1997 through March 31,
1998, the Preferred Short-Term Government Fund was managed by an unrelated third
party. All other funds are managed by unrelated investment managers. Caterpillar
Securities, Inc., a wholly-owned subsidiary of CIML, distributes the shares of
the mutual funds to the Master Trust.

The percentage of the Plan's participation in the Master Trust was determined
based on the November 30, 1998 and 1997 market values of net assets, as
accumulated by the Trustee for the investment funds of each plan.  At November
30, 1998 and 1997, the Plan's pro rata interest in the quoted market values of
net assets of each of the funds of the Master Trust was as follows:

Tax Deferred Savings Plan
Financial Statements and Additional Information
December 31, 1998 and 1997

<PAGE>

                       Report of Independent Accountants


To the Participants and Plan Administrator of the
Caterpillar Inc. Tax Deferred Savings Plan

In our opinion, the accompanying statements of net assets available for plan
benefits and the related statements of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
plan benefits of the Caterpillar Inc. Tax Deferred Savings Plan (the Plan) at
December 31, 1998 and 1997, and the changes in net assets available for plan
benefits for the years ended December 31, 1998 and 1997, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Plan's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment purposes and of reportable (5%) transactions are presented for
the purpose of additional analysis and are not a required part of the basic
financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974 (ERISA). The fund
information in the statements of net assets available for plan benefits and the
statements of changes in net assets available for plan benefits is presented for
purposes of additional analysis rather than to present the net assets available
for plan benefits and changes in net assets available for plan benefits of each
fund. These supplemental schedules and fund information are the responsibility
of the Plan's management. The supplemental schedules and fund information have
been subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

The schedules of assets held for investment purposes and of reportable (5%)
transactions that accompany the Plan's financial statements do not disclose the
historical cost of certain plan assets, and certain related sales transactions,
held by a Plan custodian.  Disclosure of this information is required by ERISA.

NOTE 1 - PLAN DESCRIPTION:
- -------------------------

The following description of the Caterpillar Inc. Tax Deferred Savings Plan (the
Plan) provides only general information.  Employees should refer to the Plan
agreement for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution plan established by Caterpillar Inc. (the
Company) to enable eligible employees of the Company and its subsidiaries (the
employers) which adopt the Plan to accumulate funds.

Participation

Employees under collective bargaining agreements to which the Plan is extended
who meet certain age, service and citizenship or residency requirements are
eligible to participate in the Plan.  Participation commences upon an eligible
employee's filing of an application with the Company.  Participating eligible
employees (the participants) elect to defer a portion of their compensation
until retirement.

Participant accounts

Accounts are maintained separately for each participant.  The participant's
separate account is credited with the participant's contribution as defined
below and an allocation of Plan earnings.  Allocations of earnings are based on
participant account balances, as defined.  The benefit to which a participant is
entitled is the benefit that can be provided from the participant's account.

Loan provisions

The Plan provides for participant loans against eligible participants' separate
account balances.  Eligible employees obtain participant loans by filing a loan
application with the Company and receiving approval thereof.  Loan amounts are
generally limited to the lesser of $50,000 or 50% of the individual
participant's account balance, within certain regulatory restrictions.  Loan
repayment terms may range from 6 to 117 months depending on the type of loan and
bear interest at the prime interest rate plus 1% rounded to the nearest whole
percent.  Repayments, including interest, are made through after-tax payroll
deductions and are credited to the individual participant's account balance.
Loan transactions are treated as a transfer to (from) the investment fund (from)
to the Loan Fund.

Contributions

Participant contributions are made through a pretax compensation deferral as
elected by the participants and are contributed to the Plan by the employer.
During 1998, the compensation deferral was limited to (a) the greater of $6,000
or 4% of the participant's compensation (limited by the Internal Revenue Code to
$10,000 in 1998) for participants earning in excess of $80,000 or (b) $10,000
for participants earning less than $80,000.

During 1997, the compensation deferral was limited to (a) the greater of $5,000
or 4% of the participant's compensation (limited by the Internal Revenue Code to
$9,500 in 1997) for participants earning in excess of $75,000 or (b) $9,500 for
participants earning less than $75,000.

Investment programs

Participants may elect to have their contributions invested in any combination
of the funds shown on the accompanying statements of changes in net assets
available for plan benefits with fund information, including a self-directed
fund option which allows participants to invest in various other mutual funds
outside of the Preferred Group of Mutual Funds.  Contributions to and
withdrawals from this self-directed fund occur through transfers to/from other
elected funds.  State Street Bank serves as custodian for funds invested through
this self-directed fund option.

Interfund transfers

Transfers of assets between investment funds are recorded on a net basis in the
statement of changes in net assets available for plan benefits with fund
information.

Vesting, distribution and plan termination

Participants are fully vested in their participant contributions.  Upon
termination of employment for any reason, including death, retirement or total
and permanent disability, or upon Plan termination, the balance or balances in
participants' accounts are distributable.

Administration

The Plan is administered by the Vice President - Human Services Division of
Caterpillar Inc., and the Benefits Funds Committee of Caterpillar Inc. is
responsible for financial aspects of the Plan.  Caterpillar Inc. and the Benefit
Funds Committee have entered into a trust agreement with The Northern Trust
Company to receive contributions, administer the assets of the Plan and
distribute withdrawals pursuant to the Plan.

Federal income tax status

The Internal Revenue Service has determined and informed the Company by letter
in February 1988, that the Plan and related trust are designed in accordance
with applicable sections of the Internal Revenue Code (IRC).  The Plan has been
amended subsequent to the amendments covered by the determination letter;
however, the Plan administrator and the Plan's legal counsel believe that the
Plan is designed and is currently being operated in compliance with the
applicable requirements of the IRC.


NOTE 2 - SUMMARY OF SIGNIFICANT
- -------------------------------
         ACCOUNTING POLICIES:
         -------------------

Basis of accounting

The Plan's accounts are maintained on the accrual basis of accounting.

Investments

The fair value of the Plan's investment in the 401(k) Master Trust (Note 4) is
based upon the beginning of the year value of the Plan's investment plus actual
contributions, transfers and allocated investment income less actual
withdrawals.  Shares of registered investment companies included in the self-
directed fund option are valued at quoted market prices which represent the net
asset value of shares held by the Plan at year end.  Income from investments is
recorded as earned.

Administrative expenses

Administrative costs, including trustee fees and certain investment costs, are
paid by the Company.

                                      -7-
<PAGE>

Use of estimates in the preparation
of financial statements

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets, liabilities, income and benefit payments.
Actual results could differ from those estimates.  The Company believes the
techniques and assumptions used in establishing these amounts are appropriate.

NOTE 3 - UNIT VALUES:
- --------------------

The Plan assigns units to participants directing investments to the Caterpillar
Common Stock Fund.  The unit values assigned by the Plan reflect the current
values of the individual fund.  Total units held (in thousands) by the Plan and
their respective unit values at each month end are as follows:

NOTE 4 - MASTER TRUST:
- ---------------------

Under a Master Trust agreement with The Northern Trust Company (the Trustee),
Part 2 of the Caterpillar Inc. Employees' Investment Plan (EIP 2), the Solar
Turbines Incorporated Savings and Investment Plan and the Caterpillar Inc. Tax
Deferred Savings Plan pool their investments in the Caterpillar Inc. 401(k)
Master Trust (the Master Trust) in exchange for a percentage of participation in
the Master Trust.

The Master Trust invests in the Preferred Group of Mutual Funds, registered
investment companies which are sponsored by Caterpillar Investment Management
Ltd. (CIML), a wholly-owned subsidiary of the Company.  The options available to
the participants through the Preferred Group of Mutual Funds are comprised of
the following:

      Preferred Stable Principal Fund
      Preferred Short-term Government Fund        Preferred Value Fund
      Preferred Growth Fund                       Preferred Fixed Income Fund
      Preferred Money Market Fund                 Preferred International Fund
      Preferred Asset Allocation Fund             Preferred Small Cap Fund

CIML manages the Preferred Small Cap Fund and the Preferred Short-Term
Government Fund; however, during the period November 1, 1997 through March 31,
1998, the Preferred Short-Term Government Fund was managed by an unrelated third
party. All other funds are managed by unrelated investment managers. Caterpillar
Securities, Inc., a wholly-owned subsidiary of CIML, distributes the shares of
the mutual funds to the Master Trust.

                                      -8-
<PAGE>

The percentage of the Plan's participation in the Master Trust was determined
based on the December 31, 1998 and 1997 market values of net assets, as
accumulated by the Trustee for the investment funds of each plan.  At December
31, 1998 and 1997, the Plan's pro rata interest in the quoted market values of
net assets of each of the funds of the Master Trust was as follows:

Investment valuation

The Master Trust's investments are stated at fair value.  Common stock and cash

     Financial Statements and Additional Information

                       Report of Independent Accountants


To the Participants and Plan Administrator of the
Solar Turbines Incorporated Savings and Investment Plan

In our opinion, the accompanying statements of net assets available for plan
benefits and the related statements of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
plan benefits of the Solar Turbines Incorporated Savings and Investment Plan
(the Plan) at December 31, 1998 and 1997, and the changes in net assets
available for plan benefits for the years ended December 31, 1998 and 1997, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Plan's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedules of assets
held for investment purposes and of reportable (5%) transactions are presented
for the purpose of additional analysis and are not a required part of the basic
financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974 (ERISA).  The fund
information in the statements of net assets available for plan benefits and the
statements of changes in net assets available for plan benefits is presented for
purposes of additional analysis rather than to present the net assets available
for plan benefits and changes in net assets available for plan benefits of each
fund.  These supplemental schedules and fund information are the responsibility
of the Plan's management.  The supplemental schedules and fund information have
been subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

The schedules of assets held for investment purposes and of reportable (5%)
transactions that accompany the Plan's financial statements do not disclose the
historical cost of certain plan assets, and certain related sales transactions,
held by a Plan custodian.  Disclosure of this information is required by ERISA.

NOTE 1 - PLAN DESCRIPTION:
- -------------------------

The following description of the Solar Turbines Incorporated Savings and
Investment Plan (the Plan) provides only general information.  Employees should
refer to the Plan agreement for a more complete description of the Plan's
provisions.

General

The Plan is a defined contribution plan established by Solar Turbines
Incorporated (the Company), a 100%-owned subsidiary of Caterpillar Inc., to
enable eligible employees of the Company and its subsidiaries (the employers) to
accumulate funds.

Participation

Hourly employees of the Company who meet certain age, service and citizenship or
residency requirements are eligible to participate in the Plan.  Participation
commences upon an eligible employee's filing of an application with the Company.
Participating eligible employees (the participants) may elect to defer a portion
of their compensation until retirement.

Participant accounts

Accounts are maintained separately for each participant.  The participant's
separate account is credited with the Participant's contribution as defined
below and an allocation of Plan earnings.  Allocations of earnings are based on
participant account balances, as defined.  The benefit to which a participant is
entitled is the benefit that can be provided from the participant's account.

Loan provisions

The Plan provides for participant loans against eligible participants' separate
account balances.  Eligible employees obtain participant loans by filing a loan
application with the Company and receiving approval thereof.  Loan amounts are
generally limited to the lesser of $50,000 or 50% of the individual
participant's account balance, within certain regulatory restrictions.  Loan
repayment terms may range from 6 to 117 months depending on the type of loan and
bear interest at the prime interest rate plus 1% rounded to the nearest whole
percent.  Repayments, including interest, are made through after-tax payroll
deductions and are credited to the individual participant's account balance.
Loan transactions are treated as a transfer to (from) the investment fund (from)
to the Loan Fund.

Contributions

Participant contributions are made through a pretax compensation deferral as
elected by the participants and are contributed to the Plan by the employer.
During 1998, the compensation deferral was limited to (a) the greater of $6,000
or 4% of the participant's compensation (limited by the Internal Revenue Code to
$10,000 in 1998) for participants earning in excess of $80,000 or (b) $10,000
for participants earning less than $80,000.

During 1997, the compensation deferral was limited to (a) the greater of $5,000
or 4% of the participant's compensation (limited by the Internal Revenue Code to
$9,500 in 1997) for participants earning in excess of $75,000 or (b) $9,500 for
participants earning less than $75,000.

Investment Programs

Participants may elect to have their contributions invested in any combination
of the funds shown on the accompanying statements of changes in net assets
available for plan benefits with fund information, including a self-directed
fund option which allows participants to invest in various other mutual funds
outside of the Preferred Group of Mutual Funds.  Contributions to and
withdrawals from this self-directed fund occur through transfers to/from other
elected funds.  State Street Bank serves as custodian for funds invested through
this self-directed fund option.

Interfund transfers

Transfers of assets between investment funds are recorded on a net basis in the
statement of changes in net assets available for plan benefits with fund
information.

Vesting, distribution and plan termination

Participants are fully vested in their participant contributions.  Upon
termination of employment for any reason, including death, retirement or total
and permanent disability, or upon Plan termination, the balance or balances in
participants' accounts are distributable.

Administration

The Plan is administered by the Vice President - Human Services Division of
Caterpillar Inc., and the Benefits Funds Committee of Caterpillar Inc. is
responsible for financial aspects of the Plan.  Caterpillar Inc. and the Benefit
Funds Committee have entered into a trust agreement with The Northern Trust
Company to receive contributions, administer the assets of the Plan and
distribute withdrawals pursuant to the Plan.

Federal income tax status

The Internal Revenue Service has determined and informed the Company by letter
dated May 30, 1986, that the Plan and related trust are designed in accordance
with applicable sections of the Internal Revenue Code (IRC).  The Plan has been
amended subsequent to the amendments covered by the determination letter;
however, the Plan administrator and the Plan's legal counsel believe that the
Plan is designed and is currently being operated in compliance with the
applicable requirements of the IRC.

NOTE 2 - SUMMARY OF SIGNIFICANT
- -------------------------------
         ACCOUNTING POLICIES:
         -------------------

Basis of accounting

The Plan's accounts are maintained on the accrual basis of accounting.

Investments

The fair value of the Plan's investment in the 401(k) Master Trust (Note 4) is
based upon the beginning of the year value of the Plan's investment plus actual
contributions, transfers and allocated investment income less actual
withdrawals.  Shares of registered investment companies included in the self-
directed fund option are valued at quoted market prices which represent the net
asset value of shares held by the Plan at year end.  Income from investments is
recorded as earned.

Administrative expenses

Administrative costs, including trustee fees and certain investment costs, are
paid by Caterpillar Inc.

                                      -7-
<PAGE>

Use of estimates in the preparation
of financial statements

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets, liabilities, income and benefit payments.
Actual results could differ from those estimates.  The Company believes the
techniques and assumptions used in establishing these amounts are appropriate.


NOTE 3 - UNIT VALUES:
- --------------------


The Plan assigns units to participants directing investments to the Caterpillar
Common Stock Fund.  The unit values assigned by the Plan reflect the current
values of the individual funds.  Total units held (in thousands) by the Plan and
their respective unit values at each month end are as follows:

NOTE 4 - MASTER TRUST:
- ---------------------

Under a Master Trust agreement with The Northern Trust Company (the Trustee),
Part 2 of the Caterpillar Inc. Employees' Investment Plan (EIP 2), the Solar
Turbines Incorporated Savings and Investment Plan and the Caterpillar Inc. Tax
Deferred Savings Plan pool their investments in the Caterpillar Inc. 401(k)
Master Trust (the Master Trust) in exchange for a percentage of participation in
the Master Trust.


The Master Trust invests in the Preferred Group of Mutual Funds, registered
investment companies  which are sponsored by Caterpillar Investment Management
Ltd. (CIML), a wholly-owned subsidiary of Caterpillar Inc.  The options
available to the participants through the Preferred Group of Mutual Funds are
comprised of the following:


      Preferred Stable Principal Fund
      Preferred Short-term Government Fund   Preferred Value Fund
      Preferred Growth Fund                  Preferred Fixed Income Fund
      Preferred Money Market Fund            Preferred International Fund
      Preferred Asset Allocation Fund        Preferred Small Cap Fund

CIML manages the Preferred Small Cap Fund and the Preferred Short-term
Government Fund; however, during the period November 1, 1997 through March 31,
1998, the Preferred Short-Term Government Fund was managed by an unrelated third
party. All other funds are managed by unrelated investment managers. Caterpillar
Securities, Inc., a wholly-owned subsidiary of CIML, distributes the shares of
the mutual funds to the Master Trust.

                                      -8-
<PAGE>

The percentage of the Plan's participation in the Master Trust was determined
based on the December 31, 1998 and 1997 market values of net assets, as
accumulated by the Trustee for the investment funds of each plan.  At December
31, 1998 and 1997, the Plan's pro rata interest in the quoted market values of
net assets of each of the funds of the Master Trust was as follows:
