      1.1.2. Stage 2: Specific Training in Mexico

            In this Stage 2, NSM will deploy its trainees groups A, B and C to
            Mexico for the practical training, in which the trainees will learn
            directly in the HYL installations the operation and maintenance
            aspects.

            The expected composition of the groups A and B is specified in the
            paragraph 1.1.3. The duration of the Specific Training in Mexico for
            each position will be defined and confirmed later by NSM and HYL.

            The composition of the third group C will be also defined later.
            However, the positions for this group will be within those specified
            in paragraph 1.1.3. The number of trainees for this group will be
            about 40 persons.

            During this stage, the trainee will observe and participate in the
            execution of activities in accordance to the position for which he
            is designated.

- --------------------------------------------------------------------------------
Agreement for Training of NSM Personnel: Appendix A                       Page 6


            At this stage, HYL will provide additional teaching material to
            complete the whole set of, in accordance to the scope of each
            position.

            Periodically, HYL will evaluate the trainees performance and will
            inform NSM of the observations and trainee notes.

            The training will be performed in English.

            The development of the training will be made following the
            requirements of the training methodology described in paragraph 2.0
            of this Appendix "A".

NSM Agreement: Appendix B                                                Page 19


TRAINING EXECUTION METHOD

To assure that the training is effective, the following method is used (Figure
No. 2):

o     DESIGN STAGE

      Initial Evaluation:

      At this step, an evaluation is made to know what is the knowledge of the
      trainee.

      Program Definition:

      With the information obtained of the initial evaluation, a program
      containing the topics that require more attention is prepared.

      In the scheme of the figure No. 3 is shown in detail this stage.

      In the scheme of the figures No. 4 and 5, is shown in detail this stage.

o     BASIC TRAINING STAGE

      Classroom and homework:

      General explanations of the topic are given in the classroom. Homework is
      normally asked during this stage.

      Field knowledge:

      Combined with the classrooms, visits and explanations at site are carried
      out.

      Workshop:

      For specific themes, frequently the workshop sessions are made for deep
      analysis.

o     CONTROL PROCESS
 
      Instructor Evaluation:

      of the trainee, and decides if he or she continues to the next training
      stage.

- --------------------------------------------------------------------------------
NSM Agreement: Appendix B                                                Page 20


o     PRACTICAL TRAINING STAGE

      Cold simulation and/or shadow training:

      The trainee directly observes the operation or maintenance activities
      together with the operator of the equipment, and affirms his knowledge of
      the matter. In some cases, simulators are run for the training.

      Foreman evaluation:

      At this stage, the foreman responsible for the activities in the plant
      evaluates the trainee and makes a decision as to whether he is ready to
      continue to the next stage.

      Hands On training stage:

      If the foreman evaluation is approved, then the trainee, under foreman and
      operator supervision, executes the operation or maintenance activities of
      the trainee position.

o     CONTROL PROCESS

      Final evaluation:

      An evaluation of his performance and a written report and for each
      trainee, is made is delivered to the customer training responsible.
