     The undersigned, Robert H. Hunsberger and Vito E. Palermo, hereby certify
that:

     1.   They are the duly elected and acting President and Secretary,
respectively, of Metawave Communications Corporation, a Delaware corporation.

     2.   The Certificate of Incorporation of this corporation was originally
filed with the Secretary of State of Delaware on July 7, 1995.

     3.   The Certificate of  Incorporation of this corporation shall be amended
and restated to read in full as follows:

                                   "ARTICLE I
                                        
     The name of this corporation is Metawave Communications Corporation (the
"Corporation").

                                   ARTICLE II

     The address of the Corporation's registered office in the State of Delaware
is 1209 Orange Street, in the City of Wilmington, County of New Castle.  The
name of its registered agent at such address is The Corporation Trust Company.

                                  ARTICLE III

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

                                   ARTICLE IV

     (A)  CLASSES OF STOCK.  The 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 One
Hundred Sixty Five Million (165,000,000)] shares, each with a par value of
$0.001 per share.  One Hundred Fifty Million (150,000,000) shares shall be
Common Stock and Fifteen Million (15,000,000) shares shall be Preferred Stock.

     (B)  The Preferred Stock may be issued from time to time in one or more
series.  The Board of Directors is hereby authorized, within the limitations and
restrictions stated in this Certificate of Incorporation, to determine or alter
the rights, preferences, privileges and restrictions granted to or imposed upon
any wholly unissued series of Preferred Stock and the number of shares
constituting any such series and the designation thereof, 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 so
decreased, the shares constituting such decrease shall resume the status which
they had prior to the adoption of the resolution originally fixing the number of
shares of such series.

                                   ARTICLE V

     The number of directors of the Corporation shall be fixed from time to time
by a bylaw or amendment thereof duly adopted by at least 66 2/3% of the Board of
Directors.

                                   ARTICLE VI

     In the event of a vacancy in the Board of Directors, the remaining
directors, except as otherwise provided by law, may exercise the powers of the
full Board of Directors until the vacancy is filled.  Vacancies in the Board of
Directors and newly created directorships resulting from any increase in the
authorized number of directors shall be filled by a vote of the majority of the
directors then in office, though less than a quorum, or by a sole remaining
director.  Any director or the entire Board of Directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of directors.

                                  ARTICLE VII
                                        
     In the election of directors, each holder of shares of any class or series
of capital stock of the Corporation shall be entitled to one vote for each share
held.  No stockholder will be permitted to cumulate votes at any election of
directors.

                                  ARTICLE VIII

     No action shall be taken by the stockholders of the Corporation other than
at an annual or special meeting of the stockholders, upon due notice and in
accordance with the provisions of the Corporation's bylaws.

                                   ARTICLE IX

     The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Amended and Restated Certificate of Incorporation,
in the manner now or hereafter prescribed by statute, and all rights conferred
upon stockholders herein are granted subject to this reservation.

                                   ARTICLE X
                                        
     The Board of Directors of the Corporation is expressly authorized to make,
alter or repeal Bylaws of the Corporation.  In addition to any requirements of
law and any other provisions hereof (and notwithstanding the fact that approval
by a lesser vote may be permitted by law or 

                                      -2-

 
any other provision hereof), the affirmative vote of the holders of at least 
66 2/3% of the voting power of the then outstanding shares of stock of all
classes and all series of the Corporation entitled to vote generally in the
election of directors, voting together as a single class, shall be required to
amend, alter, repeal, or adopt any provision inconsistent with, this Article X
or Article V hereof.

                                   ARTICLE XI

     Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide. The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of the Corporation.

                                  ARTICLE XII

     The Corporation shall have perpetual existence.

                                  ARTICLE XIII

     (A)  To the fullest extent permitted by the General Corporation Law of
Delaware, as the same may be amended from time to time, a director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director.
If the General Corporation Law of Delaware is hereafter amended to authorize,
with the approval of a corporation's stockholders, further reductions in the
liability of the Corporation's directors for breach of fiduciary duty, then a
director of the Corporation shall not be liable for any such breach to the
fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     (B)  Any repeal or modification of the foregoing provisions of this Article
XIII shall not adversely affect any right or protection of a director of the
Corporation with respect to any acts or omissions of such director occurring
prior to such repeal or modification.

                                  ARTICLE XIV

     (A)  To the fullest extent permitted by applicable law, the Corporation is
also authorized to provide indemnification of (and advancement of expenses to)
such agents (and any other persons to which Delaware law permits the Corporation
to provide indemnification) though bylaw provisions, agreements with such agents
or other persons, vote of stockholders or disinterested directors or otherwise,
in excess of the indemnification and advancement otherwise permitted by Section
145 of the Delaware General Corporation Law, subject only to limits created by
applicable Delaware law (statutory or non-statutory), with respect to actions
for breach of duty to a corporation, its stockholders, and others.

     (B)  Any repeal or modification of any of the foregoing provisions of this
Article XIV shall not adversely affect any right or protection of a director,
officer, agent or other person 

                                      -3-

 
existing at the time of, or increase the liability of any director of the
Corporation with respect to any acts or omissions of such director, officer or
agent occurring prior to such repeal or modification."

                                  *    *    *

                                      -4-

 
     The foregoing Amended and Restated Certificate of Incorporation has been
duly adopted by this Corporation's Board of Directors and stockholders in
