of the corporation.

          FOURTH: The Certificate of Incorporation of the corporation shall be
amended and restated to read in full as follows:

                                   ARTICLE I

          The name of the corporation is LogicVision, Inc.

                                   ARTICLE II

          The address of the registered office of the corporation in the State
of Delaware is 2711 Centerville Road, Suite 400, in the City of Wilmington,
County of New Castle. The name of its registered agent at such address is

                                  ARTICLE III

          The nature of the business or purposes to be conducted or promoted is

             ----------------
capital stock that the corporation shall have authority to issue is one hundred
and thirty million (130,000,000), of which one hundred and twenty-five million

<PAGE>

million (5,000,000) shares of the par value of one hundredth of one cent
($0.0001) each shall be Preferred Stock (the "Preferred Stock"). The number of
authorized shares of Common Stock or Preferred Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the then outstanding shares of
Common Stock, without a vote of the holders of the Preferred Stock, or of any
series thereof, unless a vote of any such Preferred Stock holders is required
pursuant to the provisions established by the Board of Directors of the
corporation (the "Board of Directors") in the resolution or resolutions
providing for the issue of such Preferred Stock, and if such holders of such
Preferred Stock are so entitled to vote thereon, then, except as may otherwise
be set forth in this Restated Certificate of Incorporation, the only stockholder
approval required shall be the affirmative vote of a majority of the combined
voting power of the Common Stock and the Preferred Stock so entitled to vote.

          B. Preferred Stock. The Preferred Stock may be issued in any number of
             ---------------
series, as determined by the Board of Directors. The Board of Directors is
expressly authorized to provide for the issue, in one or more series, of all or
any of the remaining shares of Preferred Stock and, in the resolution or
resolutions providing for such issue, to establish for each such series the
number of its shares, the voting powers, full or limited, of the shares of such
series, or that such shares shall have no voting powers, and the designations,
preferences and relative, participating, optional or other special rights of the
shares of such series, and the qualifications, limitations or restrictions
thereof. The Board of Directors is also expressly authorized (unless forbidden
in the resolution or resolutions providing for such issue) to increase or
decrease (but not below the number of shares of the series then outstanding) the
number of shares of any series subsequent to the issuance of shares of that
series. In case the number of shares of any such series shall be so decreased,
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.

          C. Common Stock.
             ------------

          1. Relative Rights of Preferred Stock and Common Stock. All
             ---------------------------------------------------
preferences, voting powers, relative, participating, optional or other special
rights and privileges, and qualifications, limitations, or restrictions of the
Common Stock are expressly made subject and subordinate to those that may be
fixed with respect to any shares of the Preferred Stock.

          2. Voting Rights. Except as otherwise required by law or this Restated
             -------------
Certificate of Incorporation, each holder of Common Stock shall have one vote in
respect of each share of stock held by such holder of record on the books of the
corporation for the election of directors and on all matters submitted to a vote
of stockholders of the corporation.

          3. Dividends. Subject to the preferential rights of the Preferred
             ---------
Stock, the holders of shares of Common Stock shall be entitled to receive, when
and if declared by the Board of Directors, out of the assets of the corporation
which are by law available therefor, dividends payable either in cash, in
property or in shares of capital stock.

          4. Dissolution, Liquidation or Winding Up. In the event of any
             --------------------------------------
dissolution, liquidation or winding up of the affairs of the corporation, after
distribution in full of the

                                      -2-

<PAGE>

preferential amounts, if any, to be distributed to the holders of shares of the
Preferred Stock, holders of Common Stock shall be entitled, unless otherwise
provided by law or this Restated Certificate of Incorporation, to receive all of
the remaining assets of the corporation of whatever kind available for
distribution to stockholders ratably in proportion to the number of shares of
Common Stock held by them respectively.

                                   ARTICLE V

          In furtherance and not in limitation of the powers conferred by the
laws of the State of Delaware:

          A. The Board of Directors is expressly authorized to adopt, amend or
repeal the by-laws of the corporation, provided, however, that the by-laws may
only be amended in accordance with the provisions thereof.

          B. Elections of directors need not be by written ballot unless the
by-laws of the corporation shall so provide.

          C. The books of the corporation may be kept at such place within or
without the State of Delaware as the by-laws of the corporation may provide or
as may be designated from time to time by the Board of Directors.

                                   ARTICLE VI

          No action required or permitted to be taken at any annual or special
meeting of the stockholders may be taken without a meeting and the power of
stockholders to consent in writing, without a meeting, to the taking of any
action is specifically denied. Special meetings of the stockholders of the
corporation may be called only by the Chairman of the Board or the Chief
Executive Officer of the corporation or by a resolution adopted by the
affirmative vote of a majority of the Board of Directors.

                                  ARTICLE VII

          A. Limitation on Liability. 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, except for liability (1) for any
breach of the director's duty of loyalty to the corporation or its stockholders;
(2) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law; (3) under Section 174 of the Delaware
General Corporation Law; or (4) for any transaction from which the director
derived an improper personal benefit.

          If the Delaware General Corporation Law hereafter is amended to
further eliminate or limit the liability of directors, then the liability of a
director of the corporation, in addition to the limitation on personal liability
provided herein, shall be limited to the fullest extent permitted by the amended
Delaware General Corporation Law.

          B. Indemnification. Each person who is or is made a party or is
             ---------------
threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal,

                                      -3-

<PAGE>

administrative or investigative (hereinafter a "proceeding"), by reason of the
fact that he or she, or a person of whom he or she is the legal representative,
is or was a director or officer of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to employee benefit plans, whether the basis of
such proceeding is alleged action in an official capacity as a director,
officer, employee or agent or in any other capacity while serving as a director,
officer, employee or agent, shall be indemnified and held harmless by the
corporation to the fullest extent authorized by the Delaware General Corporation
Law, as the same exists or may hereafter be amended (but, in the case of any
such amendment, only to the extent that such amendment permits the corporation
to provide broader indemnification rights than said law permitted the
corporation to provide prior to such amendment), against all expense, liability
and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or
penalties and amounts paid or to be paid in settlement) reasonably incurred or
suffered by such person in connection therewith and such indemnification shall
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that, except as provided in the second
paragraph hereof, the corporation shall indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person only if such proceeding (or part thereof) was authorized by the
Board of Directors of the corporation. The right to indemnification conferred in
this section shall be a contract right and shall include the right to be paid by
the corporation for any expenses incurred in defending any such proceeding in
advance of its final disposition; provided, however, that, if the Delaware
General Corporation Law requires, the payment of such expenses incurred by a
director or officer in his or her capacity as a director or officer (and not in
any other capacity in which service was or is rendered by such person while a
director or officer, including, without limitation, service to an employee
benefit plan) in advance of the final disposition of a proceeding, shall be made
only upon delivery to the corporation of an undertaking, by or on behalf of such
director or officer, to repay all amounts so advanced if it shall ultimately be
determined that such director or officer is not entitled to be indemnified under
this section or otherwise. The corporation may, by action of its Board of
Directors, provide indemnification to employees and agents of the corporation
with the same scope and effect as the foregoing indemnification of directors and
officers.

          If a claim under the first paragraph of this section is not paid in
full by the corporation within thirty (30) days after a written claim has been
received by the corporation, the claimant may at any time thereafter bring suit
against the corporation to recover the unpaid amount of the claim and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim. It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final disposition where the required
undertaking, if any is required, has been tendered to the corporation) that the
claimant has not met the standards of conduct which make it permissible under
the Delaware General Corporation Law for the corporation to indemnify the
claimant for the amount claimed, but the burden of proving such defense shall be
on the corporation. Neither the failure of the corporation (including its Board
of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law,

                                      -4-

<PAGE>

nor an actual determination by the corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

          The right to indemnification and the payment of expenses incurred in
defending a proceeding in advance of its final disposition conferred in this
section shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, provision of the Restated Certificate of
Incorporation, by-law, agreement, vote of stockholders or disinterested
directors or otherwise.

          C. Insurance. The corporation may maintain insurance, at its expense,
             ---------
to protect itself and any director, officer, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

          D. Repeal and Modification. Any repeal or modification of the
             -----------------------
foregoing provisions of this Article VIII shall not adversely affect any right
or protection of any director, officer, employee or agent of the corporation
existing at the time of such repeal or modification. To the fullest extent
permitted by applicable law, the Corporation is authorized to provide
indemnification of (and advancement of expenses to) agents of the Corporation
(and any other persons to which Delaware law permits the Corporation to provide
indemnification) through 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 the Corporation, its stockholders, and others.

                                  ARTICLE VIII

          The Board of Directors is expressly empowered to adopt, amend or
repeal the by-laws of the corporation; provided, however, that any adoption,
amendment or repeal of the by-laws of the corporation by the Board of Directors
shall require the approval of at least sixty-six and two-thirds percent
(66-2/3%) of the total number of authorized directors (whether or not there
exist any vacancies in previously authorized directorships at the time any
resolution providing for adoption, amendment or repeal is presented to the Board
of Directors). The stockholders shall also have the power to adopt, amend or
repeal the by-laws of the corporation, provided, however, that in addition to
any vote of the holders of any class or series of stock of the corporation
required by law or by this Restated Certificate of Incorporation, 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 stock
of the corporation entitled to vote generally in the election of directors,
voting together as a single class, shall be required for such adoption,
amendment or repeal by the stockholders of any provisions of the by-laws of the
corporation.

                                      -5-

<PAGE>

                                   ARTICLE IX

          Notwithstanding any other provision of this Restated Certificate of
Incorporation, 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 stock of the corporation entitled to vote generally in the
election of directors, voting together as a single class, shall be required to
amend in any respect or repeal this Article IX, or Articles VI, VII and VIII.

                                      * * *

          FIFTH: This Restated Certificate of Incorporation was duly adopted by
the Board of Directors of the corporation.

          SIXTH: This Restated Certificate of Incorporation was duly adopted by
the stockholders in accordance with the provisions of Sections 242 and 245 of
the General Corporation Law of the State of Delaware. Written consent of the

Incorporation in accordance with Section 228 of the General Corporation Law of
the State of Delaware.
