                           INDUSTRIAL TRAINING CORPORATION

                                ARTICLES OF AMENDMENT



                      INDUSTRIAL TRAINING CORPORATION, a Maryland corporation,
     having its principal office in Montgomery County, Maryland (hereinafter
     called "the Corporation"), hereby certifies to the State Department of
     Assessments and Taxation that:

                      FIRST:  The charter of the corporation is hereby amended
     by deleting Articles SIXTH and SEVENTH and inserting the following in lieu
     thereof:

                      "SIXTH:  (1)  The number of directors shall not be less
     than three nor more than seven, the exact number of directors to be
     determined from time to time by resolution adopted by a majority of the
     entire Board, and such exact number shall be five until otherwise
     determined by resolution adopted by a majority of the entire Board.  As
     used in this Article SIXTH, "entire Board" means the total number of
     directors which the Corporation would have if there were no vacancies.  In
     the event that the Board is increased by such a resolution, the vacancy or
     vacancies so resulting shall, unless otherwise required by law, be filled
     by a vote of the majority of the directors then in office.  No decrease in
     the Board shall shorten the term of any incumbent directors.  Unless
     otherwise required by law, only the Board of Directors shall have the
     power to fix, increase or decrease the number of directors or fill any
     vacancies in the Board which may exist.

                                       (2)  The Board of Directors shall be
     divided into three classes as nearly equal in number as may be, with the
     term of office of Class I expiring at the annual meeting of shareholders
     in 1985, of Class II expiring at the annual meeting of shareholders in
     1986, and of Class III expiring at the annual meeting of shareholders in
     1987.  The following preset directors are hereby designated initial
     members of the classes as indicated below:

       Class I               Class II                Class III
       James H. Walton       John D. Sanders         George DeVaux
       Gerald H. Kaiz        Richard E. Thomas


                      (3)      At each annual meeting of shareholders, directors
     chosen to succeed those whose terms then expire shall be elected for a
     term of office expiring at the third succeeding annual meeting of
     shareholders after their election.  When the number of directors is
     increased by the Board and any newly created directorships are filled by
     the Board, there shall be no classification of the additional directors
     until the next annual meeting of shareholders.  Directors elected to fill
     a vacancy, subject to the foregoing, shall hold office for a term expiring
     at the annual meeting at which the term of the class to which they shall
     have been elected expires.







                      "SEVENTH:  The following provisions are here by adopted
     for the purpose of defining, limiting and regulating the powers of this
     Corporation and of its directors and stockholders:

                      "A.  The shareholders of this Corporation shall not have
     the preemptive right to acquire additional shares of the Corporation's
     stock."

                      "B.  Any or all of the directors may be removed by the
     shareholders only for cause and only by the affirmative vote of seventy
     percent (70%) of all the shares entitled to be voted in the election of
     directors (considered for this purpose as one class).  For the purposes
     hereof, and except as may otherwise be provided by law, 'cause' shall mean
     conviction for a felony, or an adjudication by a court of competent juris-
     diction of negligence by the director in the performance of his duty to
     the Corporation in a matter of substantial importance to the Corporation,
     and such conviction or adjudication is no longer subject to direct appeal.

                      "C.  (1)  Except as set forth in Section (4) of this
     Article SEVENTH C:

                      (a)  any merger or consolidation of the Corporation or
     any of its 'affiliates' with another corporation or the merger of any
     other corporation into the Corporation or any of its 'affiliates';

                      (b)  any sale, lease, exchange or other disposition of
     all or any 'substantial part' of the assets of the Corporation or any of
     its 'affiliates' to or with any other corporation, person or other entity;
     or

                      (c)  any sale, lease, exchange or other disposition to
     the Corporation or any of its 'affiliates' of any assets, cash, or
     securities of any other corporation, person or entity in exchange for
     securities of the Corporation or any of its 'affiliates', shall require
     the affirmative vote or consent of the holders of shares representing

                      (i)  at least seventh percent (70%) of the votes of all
     classes of stock of the Corporation entitled to vote in the election of
     directors, considered for the purposes of this Article as one class, and

                      (ii)     at least a majority of the votes of all such
     classes of stock of the Corporation, considered for the purposes of this
     Article as one class, which are not 'beneficially owned,' directly or
     indirectly, by such other corporation, person or other entity, if, as of
     the record date for the determination of stockholders entitled to notice
     thereof and to vote thereon or consent thereto, such other corporation,
     person or other entity is the 'beneficial owner', directly or indirectly,
     of shares possessing more than ten percent (10%) of the votes of the
     outstanding shares of stock of the Corporation entitled to vote in the
     election of directors, considered for the purposes of this Article SEVENTH
     C., as one class.  Such affirmative vote or consent shall be in lieu of
     any lesser vote or consent of the holders of the stock of the Corporation

                                        - 2 -







     otherwise required by law or any agreement or contract to which the
     Corporation is a party, and shall be in addition to any class vote to
     which any class of stock may be entitled,

                      (2)  For the purposes of this Article SEVENTH C., and
     without limiting the definition of 'beneficial owner' or 'beneficially
     own', any corporation, person or other entity shall be deemed to be the
     'beneficial owner' of or to 'beneficially own' any share of stock of the
     Corporation (a) which it has the right to acquire either immediately or at
     some future date pursuant to any agreement, or upon exercise of conversion
     rights, warrants or options, or otherwise, or (b) which is 'beneficially
     owned,' directly or indirectly (including shares deemed owned through
     application of the foregoing clause (a) of this Section (2), by any other
     corporation, person or other entity either with which it is or its
     'affiliates' or 'associates' has any agreement, arrangement or understand-
     ing for the purpose of acquiring, holding, voting or disposing of stock of
     the Corporation, or which is its 'affiliate' or 'associate' as those terms
     are defined in Rule 12b-2 of the General Rules and Regulations under the
     Securities Exchange Act of 1934 as in effect from time to time or any
     successor provision.  Also, for purposes of this Article SEVENTH C., the
     'outstanding' shares of any class of stock of the Corporation shall
     include shares deemed owned through application of the foregoing clauses
     (a) and (b) of this Section (2), but shall not include any other shares
     which may be issuable either immediately or at some future date pursuant
     to any agreement, or upon exercise of conversion rights, warrants or
     options, or otherwise.

                      (3)  The Board of Directors of the Corporation shall have
     the power and duty to determine for the purposes of this Article SEVENTH
     C., on the basis of information known to the Corporation, whether (a) any
     corporation, person or other entity 'beneficially owns,' directly or
     indirectly, more than ten percent (10%) of the shares of stock of the
     Corporation entitled to vote in the election of directors, (b) any
     corporation, person or other entity is an 'affiliate' or 'associate' of
     another, (c) any proposed sale, lease, exchange or other disposition of
     part of the assets of the Corporation or any of its 'affiliates' involves
     a 'substantial part' of the assets of the Corporation or such 'affiliate',
     and (d) the issuance of shares by the Corporation to a wholly-owned sub-
     sidiary is pat of a plan to transfer such shares to another corporation,
     person or other entity which is the 'beneficial owner' of more than ten
     percent (10%) of the outstanding voting shares of the Corporation, as
     referred to in Section (4) hereof.  Any such determination made in good
     faith shall be conclusive and binding for all purposes of this Article
     SEVENTH C.

                      (4)  (a)  The provisions of this Article SEVENTH C.,
     shall not apply to any transaction described in clauses (a), (b) or (c) of
     Section (1) hereof if (i) the Board of Directors of the Corporation shall
     have approved any transaction described in Section (1) hereof prior to the
     time that such other corporation, person or other entity shall become a
     'beneficial owner,' directly or indirectly, of shares possessing more than
     ten percent (10%) of the votes of all the outstanding shares of stock of

                                        - 3 -







     the Corporation entitled to vote in the election of directors, or (ii) all
     of the outstanding shares of all classes of stock of such other corpora-
     tion, whether or not entitled to vote in the election of directors, are
     owned of record or beneficially, directly or indirectly, by the
     Corporation and the Certificate of Incorporation of the Corporation is not
     amended in connection with such transaction (or, in the events of a con-
     solidation or a merger in which the Corporation is not the survivor, the
     certificate of incorporation of the consolidated or surviving corporation
     contains provisions substantially similar to those in this Article
     SEVENTH); provided, however, that nothing in this clause (ii) shall permit
     the Corporation to issue any of its shares of stock entitled to vote in
     the election of directors to a wholly-owned subsidiary if such issuance is
     pat of a plan to transfer such shares to another corporation, person or
     other entity which is the 'beneficial owner,' directly or indirectly, of
     more than ten percent (10%) of the outstanding shares of the stock of the
     Corporation, entitled to vote in the election of directors.

                      (b)  The provisions of this Article SEVENTH C., shall not
     apply to any transaction described in clauses (a), (b) or (c) of Section
     (1) hereof if the other corporation, person or entity, after acquiring
     40 percent or more of the issued and outstanding capital stock of the
     Corporation, extended an offer for a period of thirty days after such
     acquisition, to purchase all of the remaining issued and outstanding
     capital stock of the Corporation, at a per share price not less than the
     average price paid per share for the most expensive quartile of the capi-
     tal stock of the Corporation (the "Comparable Stock") acquired by such
     other corporation, person or entity, and upon purchase terms no less
     favorable to the remaining stockholders of the Corporation than was given
     by such corporation, person or entity to the previous holders of the
     Comparable Stock.

                      (5)  In the event any transaction referred to in Section
     (1) of this Article SEVENTH C., which required the vote of the holders of
     stock of the Corporation provided for therein is approved by the stock-
     holders in accordance with the provisions thereof, such transaction shall
     not be consummated unless each of the Corporation's stockholders, who
     indicate by written notice to the Corporation prior to the consummation of
     such transaction their opposition thereto, shall receive incident to the
     consummation of any such transaction, if they so elect, a price for their
     shares of stock of the Corporation which shall not be less than the high-
     est price previously paid at any time by such other corporation, person or
     other entity referred to in Section (1) for any of its shares of the
     Corporation's stock of that class.  Such price shall be paid in cash at
     the time of consummation of the subject transaction to each of the
     Corporation's stockholders who oppose the subject transaction as referred
     to hereinbefore for any or all of their shares of Common Stock of the
     Corporation which they may tender for purchase.

                      (6)  In deciding whether any proposed transaction
     described in Section (1) of this Article SEVENTH C., should be recommended
     for approval to the stockholders of the Corporation, the Board of
     Directors shall consider all relevant factors including, but not limited

                                        - 4 -







     to, the potential social and economic effects of the transaction on the
     Corporation's employees, customers, suppliers and the community within
     which the Corporation operates.


                      "D.  (1)  No action required to be taken or which may be
     taken at any annual or special meeting of stockholders of the Corporation
     may be taken without a meeting for which prior notice in accordance with
     the bylaws has been given, and the power of stockholders to consent in
     writing, without a meeting, to the taking of any action is specifically
     denied.

                      (2)  Except as otherwise required by law, special
     meetings of stockholders of the Corporation may be called only by the
     Board of Directors pursuant to a resolution approved by a majority of the
     entire Board.

                      "E.  Notwithstanding anything to the contrary contained
