                                 PLAN OF MERGER

1.01 A plan of merger under the provisions of Articles 5.01 and 5.03 of the
Texas Business Corporation Act (the "MCA"), and Section 252 of the Delaware
General Corporation Law (the "DGCL") is adopted as follows:

           (a)    At the Effective Time, Newco will be merged into the
                  Corporation (the "Merger"). The Corporation, as it exists from
                  and after the Effective Time, is sometimes referred to herein
                  as the "Surviving Corporation". The Surviving Corporation
                  shall do business in accordance with and be governed by the
                  laws of the State of Texas.

           (b)    Surviving Corporation's name will be "L-3 Communications
                  Avisys Corporation".

1.02 The Effective Time of the Merger shall be 11:59 pm, prevailing local time
in New York City, New York, on June 16th, 2004.

                                   ARTICLE II
                              TERMS AND CONDITIONS

2.01 At the Effective Time, the existence of Newco as a distinct entity will
cease. Thereafter, Surviving Corporation will succeed to the rights, title and
interest in and to all assets and property owned by Newco, without reversion or
impairment, without any further act, and without any transfer or assignment
having occurred, but subject to any liens or other encumbrances upon such assets
and property, Surviving Corporation will also be subject to all the debts and
obligations of Newco as the primary obligor, except as otherwise provided by law
or contract, and only Surviving Corporation shall be liable for such debts or
obligations.

2.02 Surviving Corporation will carry on business with the assets of the parties
to the Merger as in existence immediately prior to the Merger.


2.03 Pursuant to Article 5.04C of the Texas Business Corporation Act ("TBCA"),
the Surviving Corporation shall be responsible and obligated to pay all fees and
franchise taxes of Newco, if any.

                                  ARTICLE III
                                CONVERTING SHARES

3.01 At the Effective Time, each full share of the issued and outstanding common
stock of the Corporation will be cancelled and extinguished and automatically
converted into the right to receive (i) a sum per share of cash determined in
accordance with that certain Merger Agreement between L-3 Communications
Corporation, a Delaware corporation, Newco and the Corporation executed June 7,
2004 ("Merger Agreement"), and (ii) a pro-rata share of any contingent
consideration, if any, as more fully described in the Merger Agreement.

3.02 All shares of capital stock of the Corporation that are owned directly or
indirectly by the Corporation or by Newco immediately prior to the Effective
Time shall be canceled as of the Effective Time without conversion, and no
consideration shall be delivered in exchange therefor.

3.03 Shares of capital stock of the Corporation issued and outstanding
immediately prior to the Effective Time that are held by any holder who is
entitled to demand and properly demands appraisal of such shares pursuant to,
and who complies in all respects with, the provisions of Articles 5.11, 5.12,
and 5.13 of the TBCA (such statutory provisions, the "Appraisal Rights
Sections", and such shares, "Dissenting Shares") shall not be converted into the
right to receive consideration, but instead the holder of such Dissenting Shares
shall be entitled solely to payment by Corporation of the fair value of such
Dissenting Shares in accordance with the provisions of the Appraisal Rights
Sections. At the Effective Time, the Dissenting Shares shall no longer be
outstanding and shall automatically be cancelled and shall cease to exist, and
each holder of Dissenting Shares shall cease to have any rights with respect
thereto, except the right to receive the fair value of such shares in accordance
with the provisions of the Appraisal Rights Sections. Notwithstanding the
foregoing, if any holder fails to perfect or otherwise waives, withdraws or
loses the right to appraisal under the Appraisal Rights Sections, or a court of
competent jurisdiction determines that such holder is not entitled to the relief
provided by the Appraisal Rights Sections, then the right of such holder to be
paid the fair value of such Dissenting $hares under the Appraisal Rights
Sections shall cease and such Dissenting Shares shall be deemed to have been
converted at the Effective Time into, and shall have become, the right to
receive cash and, subject to the terms and conditions hereof, a pro-rata share
of any contingent consideration, if any, all as more fully described in the
Merger Agreement.

3.04 Also at the Effective Time, each share of common stock, par value $0.0001
per share, of Newco issued and outstanding immediately prior to the consummation
of the Merger contemplated herein shall be converted into one validly issued,
fully paid and nonassessable share of common stock, par value $0.01 per share,
of the Surviving Corporation. Each certificate evidencing ownership of shares'
of the common stock of Newco will thereafter evidence ownership of such shares
of capital stock of the Surviving Corporation.

                                   ARTICLE IV
