Name                                                              SHARES
Grantee                                                           Shares Granted

Pursuant to action taken by the Compensation Committee of the Board of Directors
of Baker Hughes Incorporated, a Delaware corporation (the "Company"), for the
purposes of administration of the Baker Hughes Incorporated Long Term Incentive
Plan (the "Plan"), the above-named Grantee is hereby granted an incentive stock
option (within the meaning of Section 422(b) of the Internal Revenue Code) to
purchase the above number of shares of the Company's $1 par value per share
common stock at the exercise price of $21.00 for each share subject to this
option, payable at the time of exercise. Subject to the terms of the Plan and
this Stock Option Agreement regarding exercise, this option will vest and become
exercisable with respect to increments of thirty-three and one-third percent
(33-1/3%) of the shares subject to this option on the first day of October in
each of the years 1999, 2000 and 2001, provided the Grantee remains employed by
the Company or its subsidiaries. This option may not be exercised after October
1, 2008.

The following provisions will apply in the event of Grantee's termination of
employment:

                  1. If Grantee's employment is terminated for any reason (other
         than fraud, theft, embezzlement, conflict of interest, death,
         retirement or disability, which is covered by paragraphs 2, 3 and 4
         below), this option will wholly and completely terminate on the date of
         termination of employment, to the extent it is not then exercisable;
         however, to the extent the option is exercisable, Grantee shall have
         three months from the date of termination of employment to exercise the
         option but in no event later than October 1, 2008.

                  2. If Grantee's employment is terminated because of fraud,
         theft or embezzlement committed against the Company or one of its
         subsidiaries, or for conflict of interest as provided in the Plan, this
         option will wholly and completely terminate on the date of termination
         of employment.

                  3. In the event of the retirement (such that the Grantee's age
         plus years of service with the Company equals or exceeds 65) or
         disability of the Grantee, all granted but unvested options shall
         immediately vest upon the Grantee's retirement or disability. The
         Grantee shall have three years from the date of termination of
         employment due to retirement or disability to exercise this option (but
         in no event later than October 1, 2008).

                  4. Upon the death of the Grantee in active service, all
         granted but unvested options shall immediately vest upon the Grantee's
         death and otherwise shall be exercisable for a period of one year
         following Grantee's death (but in no event later than October 1, 2008).

Cashless exercise, in accordance with the terms of the Plan, shall be available
to Grantee for the shares subject to this option.

To the extent the exercise of this option results in taxable income to Grantee,
the Company is authorized to withhold from any remuneration payable to Grantee
any tax required to be withheld by reason of such taxable income.

This option is granted under and is subject to all of the provisions of the
Plan. This option is not transferable by the Grantee otherwise than by will or
by the laws of descent and distribution, and is exercisable during the Grantee's
lifetime only by the Grantee.

         Date of Grant:             October 1, 1998
