To The Secretary of State
State of New Jersey

Pursuant to the provisions of 14A:10-4.1 of the New Jersey Business Corporation
Act, it is hereby certified that:

     FIRST: The names of the merging corporations are OMR ACQUISITION
CORPORATION, which is a business corporation of the State of New Jersey, and OMR
SYSTEMS CORPORATION, which is a business corporation of the State of New Jersey.

     SECOND: The following is the Plan of Merger for merging OMR ACQUISITION
CORPORATION with and into OMR SYSTEMS CORPORATION as approved by the directors
and the shareholders entitled to vote of each of said merging corporations:

          1. OMR ACQUISITION CORPORATION and OMR SYSTEMS CORPORATION shall,
     pursuant to the provisions of the New Jersey Business Corporation Act, be
     merged with and into a single corporation, to wit, OMR SYSTEMS CORPORATION,
     which shall be the surviving corporation upon the effective date of the
     merger and which is sometimes hereinafter referred to as the "surviving
     corporation", and which shall continue to exist as said surviving
     corporation under the name OMR SYSTEMS CORPORATION pursuant to the
     provisions of the New Jersey Business Corporations Act. The separate
     existence of OMR ACQUISITION CORPORATION, which is sometimes hereinafter
     referred to as the "terminating corporation", shall cease upon said
     effective date in accordance with the provisions of said New Jersey
     Business Corporation Act.

          2. The by-laws of the terminating corporation upon the effective date
     of the merger will be the by-laws of the surviving corporation and will
     continue in full force and effect until changed, altered or amended as
     therein provided and in the manner prescribed by the provisions of the New
     Jersey Business Corporation Act.

          3. The directors and officers in office of the terminating corporation
     upon the effective date of the merger shall be the members of the first
     Board of Directors and the first officers of the surviving corporation, all
     of whom shall hold their directorships and offices until the election and
     qualification of their respective successors or until their tenure is
     otherwise terminated in accordance with the by-laws of the terminating
     corporation.


                                       1



          4. (a) Each share of common stock of the surviving corporation
     outstanding on the effective date of the merger shall, upon the effective
     date of the merger and without any action on the part of the holder
     thereof, be converted into the right to receive 29,035 fully paid, and
     nonassessable shares of Common Stock of Automatic Data Processing, Inc.
     (the indirect parent company of the terminating corporation), which shall,
     upon receipt, be validly issued and outstanding, fully paid, and
     nonassessable, and shall not be liable to any further call, nor shall the
     holder thereof be liable for any further payments with respect thereto.
     After the effective date of the merger, each holder of an outstanding
     certificate which prior thereto represented shares of Common Stock of OMR
     Systems Corporation shall be entitled, on surrender thereof to the transfer
     and exchange agent of Automatic Data Processing, to receive in exchange
     therefor a certificate or certificates representing the number of whole
     shares of Common Stock of Automatic Data Processing, Inc. to be exchanged
     for common stock of OMR Systems Corporation into which shares of Common
     Stock of OMR Systems Corporation so surrendered shall be converted as
     aforesaid. Until so surrendered, each such outstanding certificate (which
     prior to the effective date of the merger represented shares of Common
     Stock of OMR Systems Corporation) shall for all purposes evidence the
     ownership of the Common Stock of Automatic Data Processing into which such
     shares shall have been converted; provided, that dividends or other
     distributions which are payable in respect of shares of Automatic Data
     Processing, Inc. into which shares of OMR Systems Corporation shall have
     been converted shall be set aside by ADP and shall not be paid to holders
     of certificates representing such shares of Common Stock of OMR Systems
     Corporation until such certificates shall have been surrendered in exchange
     for certificates representing the Common Stock of Automatic Data
     Processing, Inc. On such surrender, the holder(s) of such shares shall be
     entitled to receive such dividends or other distributions without interest.
     Automatic Data Processing, Inc. shall not issue any fractional interest in
     shares to be exchanged for shares of Common Stock of OMR Systems
     Corporation in connection with the aforesaid conversion, and the value of
     fractional shares shall be paid in cash to the holders entitled thereto.

               (b) All shares of Common Stock of Automatic Data Processing into
     which shares of Common Stock of OMR Systems Corporation shall have been
     converted pursuant to this Plan of Merger shall be issued in full
     satisfaction of all rights pertaining to the shares of Common Stock of OMR
     Systems Corporation, as applicable, and all shares of Common Stock of OMR
     Systems Corporation shall be canceled.

               (c) If any certificate for shares of Common Stock of Automatic
     Data Processing, Inc. exchanged for shares of Common Stock of OMR Systems
     Corporation is to be reissued in a name other than that in which the
     certificate surrendered in exchange therefor is registered, it shall be a
     condition of the issuance therefor that the certificate so surrendered
     shall be properly endorsed and otherwise in proper form for transfer, that
     the transfer be in compliance with applicable federal and state securities
     laws.

               (d) The issued and outstanding shares of Common Stock of OMR
     Acquisition Corporation shall automatically be converted into 1000 shares
     of the surviving Corporation's common stock, no par value.
