                                FIRST AMENDMENT
                              OF ESI PENSION PLAN
                              -------------------

          This First Amendment of ESI Pension Plan (the "Plan") is adopted by
ITT Educational Services, Inc. (the "Employer").

                                  Background
                                  ----------

          The Employer originally established the Plan effective June 9, 1998.

          The Employer now wishes to amend the Plan as permitted under Section
12.01of the Plan.

                                   Amendment
                                   ---------

          Effective June 9, 1998, Plan is amended as follows:

             The definition of "Beneficiary" at Section 2.01 is amended to read
as follows:

               "Beneficiary" means the person or persons designated pursuant to
          Section 7.15 to receive benefits under the Plan after a Member's
          death.

                    A new Section 7.15 is added to the Plan to read as follows:

               Section 7.15. Beneficiaries. A Member's Beneficiary will be
               ------------  -------------
          determined pursuant to this Section.

                    (a) Except as provided pursuant to a Qualified Joint and
               Survivor Annuity or a Qualified Preretirement Survivor Annuity,
               the Member's Beneficiary will be the person or persons, including
               a trustee, designated in writing by a Member pursuant to
               practices of, or rules prescribed by, the Committee, as the
               recipient of a benefit payable under the Plan following the
               Member's death. To be effective, a Beneficiary designation must
               be filed with the Committee during the Member's life.

                    (b) If no person has been designated as the Beneficiary of a
               Member, or if no person so designated survives the Member, then
               the Beneficiary will be determined as follows:

                        (1) If the Member is survived by a Spouse, the Spouse
                    will be the Member's Beneficiary.

                                      -1-

                         (2) If the Member is not survived by a Spouse, the
                    Member's estate will be the Member's Beneficiary.

     If any amount becomes payable under the Plan to a Beneficiary who survives
     the Member but dies before receiving the benefit due him, and if the Member
     has not named a contingent Beneficiary who survives the Member, that amount
     will be paid in a lump sum as soon as administratively feasible following
     the Beneficiary's death to the Beneficiary's estate.

          This First Amendment of the Plan is executed this 20th day of March,
2000.
