SECTION 4. SUPPLEMENTAL THRIFT FEATURE ACCOUNT BENEFITS.

For each month in which Company Contributions to a Participant's account in the
Thrift Feature are, or would be, limited by the Pay Limitations and/or by a
voluntary salary reduction to the KEDCP, a Benefit amount shall be credited to
his or her Supplemental Thrift Feature Account no later than the end of the
month following the Valuation Date that Company contributions are made to the

investment funds and in the same proportions as the Participant has directed his
or her latest available investment allocation for Deposits to the Thrift
Feature.

SECTION 4.1 SUPPLEMENTAL THRIFT FEATURE ACCOUNT EARNINGS

The Supplemental Thrift Feature Account shall be eligible to be invested in the
same investment funds as are made available to Participants in the Thrift

value of such deemed investment funds in this Plan shall be determined to be the
same share value as the actual value of shares in the investment funds of the

though the deemed amounts were actually invested in the CPSP. However, to the
extent that earnings in the form of dividends on Company Stock in the CPSP are
eligible to be passed through to the Participant, such dividends will be deemed
to have been reinvested in the Company Stock Fund of this Plan, without regard
to whether the Participant has made a pass through election under the CPSP.

SECTION 5. SUPPLEMENTAL STOCK SAVINGS FEATURE ACCOUNT BENEFITS.

For each month in which a Semiannual Allocation or Supplemental Allocation (as
defined in the CPSP) to a Participant's account in the Stock Savings Feature is,
or would be, limited by the Pay Limitations and/or by a voluntary salary
reduction under the KEDCP, a Benefit amount shall be credited to his or her
Supplemental Stock Savings Feature Account. The amount to be credited shall be
calculated in shares in the Leveraged Stock Fund of this Plan as though the
Participant had made Supplemental Stock Savings Contributions and shall be equal
to (i) the Participant's Supplemental Stock Savings Contributions during the
applicable Allocation Period (as defined in the CPSP) multiplied by the
applicable Allocation Ratio, divided by (ii) the share value for the Leveraged
Stock Fund of the CPSP on the applicable Allocation Date. This amount shall be
credited no later than the end of the month following the Valuation Date that
the Semiannual Allocation or Supplemental Allocation to the Leveraged Stock Fund
would have been made had the Participant received a Semiannual Allocation or
Supplemental Allocation under the Stock Savings Feature. A share in the
Leveraged Stock Fund of the Supplemental Stock Savings Feature Account shall
have a value equivalent to a share in the Leveraged Stock Fund of the CPSP.

SECTION 5.1 SUPPLEMENTAL STOCK SAVINGS ACCOUNT FEATURE EARNINGS

After being initially invested in the Leveraged Stock Fund account, the amounts
in the Participant's Supplemental Stock Savings Feature Account shall thereafter
be eligible to be invested in the same investment funds as are made available to


                                      -10-
<PAGE>


Participants in the CPSP from time to time. While such investments shall consist
solely of book entries and shall not actually be invested in such funds, the
book entry share value of such deemed investment funds in this Plan shall be
determined to be the same share value as the actual value of shares in the
investment funds of the CPSP. The amounts deemed invested in this Plan shall be
valued at the same time and in the same manner as though they were actually
invested in the CPSP. Also, deemed investments in the Participant's Supplemental
Stock Savings Feature Account may be exchanged into other available investment
funds in the same manner, at the same times, and subject to the same limitations
as though the deemed amounts were actually invested in the CPSP. However, to the
extent that earnings in the form of dividends on Company Stock in the CPSP are
eligible to be passed through to the Participant, such dividends will be deemed
to have been reinvested in the Company Stock Fund of this Plan, without regard
to whether the Participant has made a pass through election under the CPSP.

SECTION 6. PAYMENT.

If a Participant terminates employment with the Affiliated Group for any reason
except death, Disability, Layoff during or after the year in which the
Participant reaches age 50, or Retirement, Benefits which the Participant is
eligible to receive under this Plan shall be paid in one lump sum cash payment
as soon as practicable following his or her termination. If a Participant dies
prior to Retirement, Benefits which the Participant is eligible to receive under
this Plan shall be paid in one lump sum cash payment to the Participant's
Beneficiary as soon as practicable after his or her death. If a Participant
Retires, is

becomes Disabled, Benefits which the Participant is eligible to receive under
this Plan shall be paid in one lump sum cash payment as soon as practicable
following the Participant's Retirement, Layoff, determination of Disability or
termination of employment; provided that such a Participant may indicate a
preference to defer part or all of such lump sum cash payment under the terms of
the KEDCP.

All lump sum cash payments shall be made only as of a Valuation Date and shall
be net of withholding for applicable taxes required by law.

The Chief Executive Officer of ConocoPhillips, with respect to Participants who
are not subject to Section 16 of the Exchange Act, and the Committee, with
respect to Participants who are subject to Section 16 of the Exchange Act, shall
consider such indication of preference and shall respectively decide in the
Chief Executive Officer's or the Committee's sole discretion whether to accept
or reject the preference expressed. In the event the Chief Executive Officer or
the Committee, as applicable, accepts such Participant's preference, the
Participant's Benefit from this Plan shall be credited as an Award under the
KEDCP as soon as practicable after the Participant's Retirement, Layoff or the
date the Participant is determined to be Disabled.
