                         FEDERAL TECHNOLOGY CORPORATION
                            (a Virginia Corporation)

Microdyne and FTC agree to merge (the "Merger").

     Second: The name and place of incorporation of each party to these Articles

     Fifth: The terms and conditions of the transaction set forth in these

Articles in the manner and by the vote required by its Charter and the laws of
the state of its incorporation. The manner of approval was as follows:

          (a) The Board of Directors of Microdyne at a meeting held on February
     5, 1991, and the Board of Directors or FTC by written consent dated March
     7, 1991 signed by all Directors and filed with the minutes of proceedings
     of the board of Directors of FTC, adopted a resolution which declared that
     the proposed Merger was advisable on substantially the terms and conditions
     set forth or referred to in the resolution and directed





     that the proposed Merger be submitted for consideration, in the case of
     Microdyne, at a special meeting of the stockholders and, in the case of
     FTC, by unanimous consent of its stockholders.

          (b) Notice which stated that a purpose of the meeting was to act on
     the proposed Merger was given by Microdyne as required by law. Notice which
     stated that a purpose of the meeting was to act on the proposed Merger was
     waived by the stockholders of FTC.

     at a special meeting of stockholders held June 20, 1991 by the affirmative
     vote of at least a majority of all the votes entitled to be cast on the

     stock of all classes of FTC is $200.

     Eighth: The manner and basis of converting or exchanging issued stock of
the merging corporations into different stock of a corporation or other

          (a) Each issued and outstanding share of the Common Stock of FTC at
     the Effective Time (as defined in Article NINTH) (other than Dissenters'
     Stock (as defined below)) shall cease to be outstanding and shall be
     converted into 20,152,506 shares of Common Stock of Microdyne (the
     "Exchange Ratio") (9,250,000 shares in the aggregate). No fractional shares
     of Microdyne Common Stock shall be issued in the Merger and all fractional
     share interests shall be canceled. At the Effective Time, all rights with
     respect to FTC Common Stock existing pursuant to stock options granted by
     FTC under the FTC Long-Term Incentive Plan ("FTC Options") which are
     outstanding at the Effective Time, whether or not then exercisable, shall
     be converted into and become rights with respect to Microdyne Common Stock,
     and Microdyne shall assume each of such FTC Options which will thereafter
     be


                                    2


     governed by the terms of the FTC Stock Option Plan and the stock option
     agreement by which it is evidenced. From and after the Effective Time (i)
     each such FTC Option may be exercised solely for shares of Microdyne Common
     Stock, (ii) the number of shares of Microdyne Common Stock subject to such
     FTC Option shall be equal to the number of shares of FTC Common Stock
     subject to such FTC Option immediately prior to the Effective Time times
     the Exchange Ratio, and (iii) the per share exercise price under each FTC
     option shall be adjusted by dividing the per share exercise price, under
     each such FTC Option by the Exchange Ratio.

          (b) Each issued and outstanding share of Common Stock of Microdyne at
     the Effective Time shall remain outstanding as one share of Common Stock of
     Microdyne.

          (c) (i) Prior to the Effective Time provided in Article NINTH,
     Microdyne shall enter into an Exchange Agent Agreement with Crestar Bank
     (the "Exchange Agent").

               (ii) Promptly after the Effective Time, the Exchange Agent, shall
          mail to each record holder, as of the Effective Time, of an
          outstanding certificate or certificates which immediately prior to the
          Effective Time represented shares of Common Stock of FTC (the
          "Certificates") a form letter of transmittal and instructions for use
          in effecting the surrender of the Certificates in exchange for
          Microdyne Common Stock as provided in Article EIGHTH.

               (iii) Upon surrender to an Exchange Agent of a Certificate
          representing Common Stock of FTC, together with such letter of
          transmittal duly executed, the holder of such Certificate shall be
          entitled to receive in exchange therefor the number of shares of
          Common Stock of Microdyne provided in Article EIGHTH. In addition,
          Certificates surrendered for exchange by any person who is an
          "affiliate" of FTC for purposes of Rule 145(c) under the Securities
          Act of 1933 shall not be exchanged for certificates representing
          shares of Microdyne Common Stock until Microdyne has received a
          written agreement from such person in form and substance satisfactory
          to Microdyne providing that such person will not dispose of Microdyne
          Common Stock received in the Merger except in compliance with the
          Securities Act of 1933 and the rules and regulations thereunder. If
          Microdyne Common Stock is to be issued to a person other than the
          person in whose name the Certificate surrendered is registered, it
          shall be a condition of issuance that the Certificate representing
          Common Stock of FTC so surrendered shall be properly endorsed or
          otherwise in proper form for transfer and that the person requesting
          such transfer shall pay any transfer or other taxes required by reason
          of the payment to a person other than the registered holder of the
          Certificate surrendered or established to the satisfaction of the
          Surviving Corporation that such tax has been paid or is not
          applicable. Until surrendered in accordance with the provisions
          hereof, each Certificate representing FTC Common Stock shall represent
          for all purposes only the right to receive the number of shares of
          Microdyne Common Stock provided in Article EIGHTH.

               (iv) After the Effective Time, there shall be no transfers on the
          stock transfer books of the Surviving Corporation of the shares of FTC
          Common Stock. If, after the Effective Time, Certificates (other than
          Certificates at that time representing Dissenters'

                                       3


          Stock) are presented to the Surviving Corporation, they shall be
          canceled and exchanged for shares of Microdyne Common Stock as
          provided in Article EIGHTH.

               (v) Former shareholders of FTC shall be entitled to vote after
          the Effective Time at any meeting of Microdyne shareholders the number
          of shares of Microdyne Common Stock into which their respective shares
          of FTC Common Stock are converted, regardless of whether such holders
          have exchanged their certificates representing FTC Common Stock for
          certificates representing Microdyne Common Stock in accordance with
          the provisions of this Article EIGHTH. Whenever a dividend is declared
          by Microdyne on the Microdyne Common Stock, the record date for which
          is at or after the Effective Time, the declaration shall include
          dividends on all shares issuable pursuant to these Articles of Merger,
          but beginning 12 months after the Effective Time no dividend or other
          distribution payable to the holders of record of Microdyne Common
          Stock as of any time after the Effective Time shall be paid to the
          holder of any certificate representing shares of FTC Common Stock
          issued and outstanding at the Effective Time until such holder
          physically surrenders such certificate for exchange as provided in
          this Article EIGHTH. However, upon surrender of a Certificate, the
          Microdyne Common Stock certificate to be issued pursuant to this
          Article EIGHTH together with all such withheld dividends or other
          distributions, without interest, shall be delivered and paid with
          respect to each share represented by such certificate.

               (vi) Shares of FTC Common Stock issued and outstanding
          immediately prior to the Effective Time which are held by a
          stockholder who has the right (to the extent such right is available
          by law) to demand and receive payment of the fair value of his shares
          of FTC Common Stock pursuant to Section 13.1-730 of the Virginia Stock
          Corporation Act ("Dissenters' Stock") shall be canceled and shall not
          be converted into the consideration provided in this Article EIGHTH

          dissent or shall have effectively withdrawn or lost such right under
          the Virginia Stock Corporation Act, as the case may be. If such holder
          shall have so failed to perfect or shall have effectively withdrawn or
          lost such right, his shares of FTC Common Stock shall thereupon be
          deemed to have been converted into, at the Effective Time, the right
          to receive Microdyne Common Stock as provided in this Article EIGHTH.

     Ninth: (a) The Merger Agreement may be terminated at any time prior to the
