                           AMENDMENT NO. 1999-1 TO THE
                         1993 EMPLOYEE STOCK BONUS PLAN

                  This Amendment No. 1999-1 is made to the Baker Hughes
Incorporated 1993 Employee Stock Bonus Plan ("the Plan"). Capitalized terms used
but not defined herein shall have the meanings ascribed to them in the Plan.

                  WHEREAS, Baker Hughes Incorporated (the "Company") has
determined that it is in its best interest and that of its stockholders to amend
the Plan as set forth herein;

                  NOW, THEREFORE, the Plan is amended as follows:

                  1. Clauses (ii) and (iii) of the first sentence of Paragraph 5
of the Plan are amended in their entirety to read as follows:

                  "(ii) the occurrence of a Change in Control other than an
                  event described only in clause (iii) of the definition of
                  Change in Control set forth in Paragraph 5 of the Plan, and
                  (iii) the termination of the eligible employee's employment if
                  (a) such eligible employee's employment is terminated by the
                  Company without Cause prior to a Change in Control (whether or
                  not a Change in Control ever occurs) and such termination was
                  at the request or direction of a Person who has entered into
                  an agreement with the Company the consummation of which would
                  constitute a Change in Control, (b) such eligible employee
                  terminates his or her employment for Good Reason prior to a
                  Change in Control (whether or not a Change in Control ever
                  occurs) and the circumstance or event which constitutes Good
                  Reason occurs at the request or direction of the Person
                  described in clause (a), (c) such eligible employee's
                  employment is terminated by the Company without Cause or by
                  the eligible employee for Good Reason and such termination or
                  the circumstance or event which constitutes Good Reason is
                  otherwise in connection with or in anticipation of a Change in
                  Control (whether or not a Change in Control ever occurs) or
                  (d) such eligible



                                       1


   2


                  employee's employment is terminated by the Company without
                  Cause or by the eligible employee for Good Reason, in either
                  case within 2 years following the occurrence of a Change in
                  Control described in clause (iii) of the definition of Change
                  in Control set forth in Paragraph 5 of the Plan."

                  2 The definition of Change in Control set forth in Paragraph 5
of the Plan is amended in its entirety to read as follows:

                           "A "Change in Control" shall be deemed to have
                  occurred if the event set forth in any one of the following
                  paragraphs shall have occurred:

                           (i) any Person is or becomes the Beneficial Owner,
                  directly or indirectly, of securities of the Company (not
                  including in the securities beneficially owned by such Person
                  any securities acquired directly from the Company or its
                  affiliates) representing 20% or more of the combined voting
                  power of the Company's then outstanding securities, excluding
                  any Person who becomes such a Beneficial Owner in connection
                  with a transaction described in clause (a) of paragraph (iii)
                  below; or

                           (ii) the following individuals cease for any reason
                  to constitute a majority of the number of directors then
                  serving: individuals who, on the date hereof, constitute the
                  Board of Directors of the Company and any new director (other
                  than a director whose initial assumption of office is in
                  connection with an actual or threatened election contest
                  relating to the election of directors of the Company) whose
                  appointment or election by the Board of Directors of the
                  Company or nomination for election by the Company's
                  stockholders was approved or recommended by a vote of at least
                  two-thirds (2/3) of the directors then still in office who
                  either were directors on the date hereof or whose appointment,
                  election or nomination for election was previously so approved
                  or recommended; or

                           (iii) there is consummated a merger or consolidation
                  of the Company or any direct or indirect subsidiary of the
                  Company with any other corporation, other than (a) a merger or
                  consolidation which would result in the voting 


                                       2

   3


                  securities of the Company outstanding immediately prior to
                  such merger or consolidation continuing to represent (either
                  by remaining outstanding or by being converted into voting
                  securities of the surviving entity or any parent thereof), in
                  combination with the ownership of any trustee or other
                  fiduciary holding securities under an employee benefit plan of
                  the Company or any subsidiary of the Company, at least 65% of
                  the combined voting power of the securities of the Company or
                  such surviving entity or any parent thereof outstanding
                  immediately after such merger or consolidation, or (b) a
                  merger or consolidation effected to implement a
                  recapitalization of the Company (or similar transaction) in
                  which no Person is or becomes the Beneficial Owner, directly
                  or indirectly, of securities of the Company (not including in
                  the securities Beneficially Owned by such Person any
                  securities acquired directly from the Company or its
                  Affiliates other than in connection with the acquisition by
                  the Company or its Affiliates of a business) representing 20%
                  or more of the combined voting power of the Company's then
                  outstanding securities; or

                           (iv) there is consummated a merger or consolidation
                  of the Company or any direct or indirect subsidiary of the
                  Company with any other corporation, other than a merger or
                  consolidation immediately following which the individuals who
                  comprise the Board immediately prior thereto constitute at
                  least a majority of the board of directors of the Company, the
                  entity surviving such merger or consolidation or any parent
                  thereof (or a majority plus one member where such board
                  comprises an odd number of members); or

                           (v) the stockholders of the Company approve a plan of
                  complete liquidation or dissolution of the Company or there is
                  consummated an agreement for the sale or disposition by the
                  Company of all or substantially all of the Company's assets,
                  other than a sale or disposition by the Company of all or
                  substantially all of the Company's assets to an entity, at
                  least 65% of the combined voting power of the voting
                  securities of which are owned by stockholders of the Company
                  in substantially the 


                                       3

   4


                  same proportions as their ownership of the Company immediately
                  prior to such sale.

                  Notwithstanding the foregoing, a "Change in Control" shall not
                  be deemed to have occurred by virtue of the consummation of
                  any transaction or series of integrated transactions
                  immediately following which the record holders of the common
                  stock of the Company immediately prior to such transaction or
                  series of transactions continue to have substantially the same
                  proportionate ownership in an entity which owns all or
                  substantially all of the assets of the Company immediately
                  following such transaction or series of transactions".

                  3 The second sentence of Paragraph 6 of the Plan is amended by
inserting immediately prior to the "." at the end thereof the following:

                  "other than an event described only in clause (iii) of the
                  definition of Change in Control set forth in Section 5 of the
                  Plan; and provided further, that the provisions of this
                  sentence shall be inapplicable to any sale of Option Shares by
                  an employee holding a Stock Award if such sale occurs at any
                  time following a Qualifying Termination."

                  4 Clause (ii) of Paragraph 7 of the Plan is amended in its
entirety to read as follows:

                  " (ii) the occurrence of a Change in Control other than an
                  event described only in clause (iii) of the definition of
                  Change in Control set forth in Section 5 of the Plan."

                  The effective date of this Amendment No. 1999-1 shall be
January 27, 1999; provided, however, that, in the event that (A) the Company is
party to a transaction which is otherwise intended to qualify for "pooling of
interests" accounting treatment, (B) such transaction constitutes a Change in
Control within the meaning of the Plan and (C) individuals who satisfy the
requirements in clauses (i) and (ii) below constitute at least two-thirds (2/3)
of the number of directors of the entity surviving such transaction or any
parent thereof: individuals who (i) immediately prior to such transaction
constitute the Board of Directors of the Company and (ii) on the date hereof
constitute the Board of Directors of the Company 



                                       4

   5

and any new director (other than a director whose initial assumption of office
is in connection with an actual or threatened election contest relating to the
election of directors of the Company) whose appointment or election by the Board
of Directors of the Company or nomination for election by the Company's
stockholders was approved or recommended, by a vote of at least two-thirds (2/3)
of the directors then still in office who either were directors on the date
hereof or whose appointment, election or nomination for election was previously
so approved or recommended then (a) this Amendment No. 1999-1 shall, to the
extent practicable, be interpreted so as to permit such accounting treatment,
and (b) to the extent that the application of clause (a) of this sentence does
not preserve the availability of such accounting treatment, then, to the extent
that any provision or combination of provisions of this Amendment No. 1999-1
disqualifies the transaction as a "pooling" transaction (including, if
applicable, this entire Amendment No. 1999-1), the Board of Directors of the
Company shall amend such provision or provisions if and to the extent necessary
(including declaring such provision or provisions to be null and void as of the
date hereof) so that such transaction may be accounted for as a "pooling of
interests." All determinations with respect to this paragraph shall be made by
the Company, based upon the advice of the accounting firm whose opinion with
respect to "pooling of interests" is required as a condition to the consummation
of such transaction. Except as herein modified, the Plan shall remain in full
force and effect.
