                              CORAL SYSTEMS, INC.


                                     I.

         The name of this corporation is Coral Systems, Inc.

                                     II.

         The address of the registered office of the Corporation in the State
of Delaware is: 

                          The Corporation Trust Company 
                          1209 Orange Street 
                          Wilmington, DE  19801 
                          County of New Castle


                                    III.

         The purpose of the Corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.


                                     IV.

         This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares which the corporation is authorized to issue is thirty 
million (30,000,000) shares, (i) twenty-five million (25,000,000) shares of 
which shall be Common Stock (the "Common Stock"), five million (5,000,000) 
shares of which shall be Preferred Stock (the "Preferred Stock").  The Common 
Stock and the Preferred Stock shall have a par value of one-tenth of one cent 
($.001).

         The Preferred Stock may be issued from time to time in one or more
series.  The Board of Directors is hereby authorized, by filing a certificate
(a "Preferred Stock Designation") pursuant to the Delaware General Corporation
Law, to fix or alter from time to time the designation, powers, preferences and
rights of the shares of each such series and the qualifications, limitations or
restrictions of any wholly unissued series of Preferred Stock, and to establish
from time to time the number of shares constituting any such series or any of
them; and to increase or decrease the number of shares of any series subsequent
to the issuance of shares of that series, but not below the number of shares of
such series then outstanding.  In case the number of shares of any series shall
be decreased in accordance with the foregoing sentence, the shares constituting
such decrease shall resume the status that they had prior to the adoption of
the resolution originally fixing the number of shares of such series.





                                     1

                                     V.

         For the management of the business and for the conduct of the affairs
of the Corporation, and in further definition, limitation and regulation of the
powers of the Corporation, of its directors and of its stockholders or any
class thereof, as the case may be, it is further provided that:

         A.
                 1.       The management of the business and the conduct of the
affairs of the Corporation shall be vested in its Board of Directors.  The
number of directors which shall constitute the whole Board of Directors shall
be fixed exclusively by one or more resolutions adopted by the Board of
Directors.

                 2.       Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances,
following the closing of the initial public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the "1933
Act"), covering the offer and sale of Common Stock to the public (the "Initial
Public Offering"), the directors shall be divided into three classes designated
as Class I, Class II and Class III, respectively. Directors shall be assigned
to each class in accordance with a resolution or resolutions adopted by the
Board of Directors.  At the first annual meeting of stockholders following the
closing of the Initial Public Offering, the term of office of the Class I
directors shall expire and Class I directors shall be elected for a full term
of three years.  At the second annual meeting of stockholders following the
Initial Public Offering, the term of office of the Class II directors shall
expire and Class II directors shall be elected for a full term of three years.
At the third annual meeting of stockholders following the Initial Public
Offering, the term of office of the Class III directors shall expire and Class
III directors shall be elected for a full term of three years.  At each
succeeding annual meeting of stockholders, directors shall be elected for a
full term of three years to succeed the directors of the class whose terms
expire at such annual meeting.
         Notwithstanding the foregoing provisions of this Article, each
director shall serve until his successor is duly elected and qualified or until
his death, resignation or removal.  No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

                 3.       Subject to the rights of the holders of any series of
Preferred Stock, no director shall be removed without cause.  Subject to any
limitations imposed by law, the Board of Directors or any individual director
may be removed from office at any time with cause by the affirmative vote of
the holders of a majority of the voting power of all the then-outstanding
shares of voting stock of the Corporation entitled to vote at an election of
directors (the "Voting Stock").

                 4.       Subject to the rights of the holders of any series of
Preferred Stock, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors, shall,
unless (i) the Board of Directors determines by resolution that any such
vacancies or newly created directorships shall be filled by the stockholders,
or (ii) as otherwise provided by





                                     2

law, be filled only by the affirmative vote of a majority of the directors then
in office, even though less than a quorum of the Board of Directors, and not by
the stockholders.  Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the director
for which the vacancy was created or occurred and until such director's
successor shall have been elected and qualified.

         B.
                 1.       Subject to paragraph (h) of Section 43 of the Bylaws,
the Bylaws may be altered or amended or new Bylaws adopted by the affirmative
vote of at least sixty-six and two-thirds percent (66-2/3%) of the voting power
of all of the then-outstanding shares of the Voting Stock.  The Board of
Directors shall also have the power to adopt, amend, or repeal Bylaws.

                 2.       The directors of the Corporation need not be elected
by written ballot unless the Bylaws so provide.

                 3.       No action shall be taken by the stockholders of the
Corporation except at an annual or special meeting of stockholders called in
accordance with the Bylaws, and following the closing of the Initial Public
Offering, no action shall be taken by the stockholders by written consent.

                 4.       Special meetings of the stockholders of the
Corporation may be called, for any purpose or purposes, by (i) the Chairman of
the Board of Directors, (ii) the Chief Executive Officer or (iii) the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously
authorized directorships at the time any such resolution is presented to the
Board of Directors for adoption).

                 5.       Advance notice of stockholder nominations for the
election of directors and of business to be brought by stockholders before any
meeting of the stockholders of the Corporation shall be given in the manner
provided in the Bylaws of the Corporation.

                 6.       At all meetings of stockholders, one-third of the
votes entitled to be cast on any matter by each voting group to vote on a
matter, represented in person or by proxy, shall constitute a quorum of that
voting group for action on that matter.

                 7.       Except as provided by law, no stockholder of the
Corporation shall have any preemptive or, unless expressly agreed to in writing
by the Corporation, any other right to subscribe for any additional unissued or
treasury shares of stock or for other securities of any class, or for rights,
warrants or options to purchase stock, or for scrip, or for securities of any
kind convertible into stock or carrying stock purchase warrants or privileges.


                                     VI.

         A.      A director of the corporation shall not be personally liable
to the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders,





                                     3
   5



(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 174 of the
Delaware General Corporation Law, or (iv) for any transaction from which the
director derived an improper personal benefit.  If the Delaware General
Corporation Law is amended after approval by the stockholders of this Article
to authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director shall be eliminated or
limited to the fullest extent permitted by the Delaware General corporation
Law, as so amended.

         B.      Any repeal or modification of this Article VI shall be
prospective and shall not affect the rights under this Article VI in effect at
the time of the alleged occurrence of any act or omission to act giving rise to
liability or indemnification.

                                        VII.

         A.      The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, except as provided in paragraph
B of this Article VII, and all rights conferred upon the stockholders herein
are granted subject to this reservation.

         B.      Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser
vote or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the Voting Stock required by law, this
Certificate of Incorporation or any Preferred Stock Designation, following the
Initial Public Offering the affirmative vote of the holders of at least
sixty-six and two-thirds percent (66-2/3%) of the voting power of all of the
then-outstanding shares of the Voting Stock, voting together as a single class,
shall be required to alter, amend or repeal Articles V, VI, and VII (other than
any amendment of such Articles in connection with a restatement of the
Certificate of Incorporation).
