                           AMENDED AND RESTATED BYLAWS

                                       OF

                               OPTIVA CORPORATION



                               SECTION 1. OFFICES

        The principal office of the corporation shall be located at the
principal place of business or such other place as the Board of Directors
("Board") may designate. The corporation may have such other offices, either
within or without the State of Washington, as the Board may designate or as the
business of the corporation may require from time to time.

                             SECTION 2. SHAREHOLDERS

2.1     ANNUAL MEETING

        The annual meeting of the shareholders shall be held each year within 90
to 180 days after the fiscal year end of the corporation at a date, time and
location determined by resolution of the Board of Directors, for the purpose of
electing Directors and transacting such other business as may properly come
before the meeting. At any time prior to the commencement of the annual meeting,
the Board may postpone the annual meeting for a period of up to one hundred
twenty (120) days from the date fixed for such meeting in accordance with this
Subsection 2.1.

2.2     SPECIAL MEETINGS

        The Chairman of the Board, the President or the Board may call special
meetings of the shareholders for any purpose. Further, a special meeting of the
shareholders shall be held if the holders of not less than 25% of all the votes
entitled to be cast on any issue proposed to be considered at such special
meeting have dated, signed and delivered to the Secretary one or more written
demands for such meeting, describing the purpose or purposes for which it is to
be held.

2.3     MEETINGS BY COMMUNICATION EQUIPMENT

        Shareholders may participate in any meeting of the shareholders by any
means of communication by which all persons participating in the meeting can
hear each other during the meeting. Participation by such means shall constitute
presence in person at a meeting.


                                     Page 1
<PAGE>   7

2.4     DATE, TIME AND PLACE OF MEETING

        Except as otherwise provided herein, all meetings of shareholders,
including those held pursuant to demand by shareholders as provided herein,
shall be held on such date and at such time and place, within or without the
State of Washington, designated by or at the direction of the Board.

2.5     BUSINESS FOR SHAREHOLDERS' MEETINGS

        2.5.1  BUSINESS AT ANNUAL MEETINGS

        In addition to the election of directors, other proper business may be
transacted at an annual meeting of shareholders, provided that such business is
properly brought before such meeting. To be properly brought before an annual
meeting, business must be (a) brought by or at the direction of the Board or (b)
brought before the meeting by a shareholder pursuant to written notice thereof,
in accordance with subsection 2.5.3 hereof, and received by the Secretary not
fewer than 60 nor more than 90 days prior to the date specified in subsection
2.1 hereof for such annual meeting (or if less than 60 days' notice or prior
public disclosure of the date of the annual meeting is given or made to the
shareholders, not later than the tenth day following the day on which the notice
of the date of the annual meeting was mailed or such public disclosure was
made). No business shall be conducted at any annual meeting of shareholders
except in accordance with this subsection 2.5.1. If the facts warrant, the
Board, or the chairman of an annual meeting of shareholders, may determine and
declare (a) that a proposal does not constitute proper business to be transacted
at the meeting or (b) that business was not properly brought before the meeting
in accordance with the provisions of this subsection 2.5.1 and, if, in either
case, it is so determined, any such business shall not be transacted. The
procedures set forth in this subsection 2.5.1 for business to be properly
brought before an annual meeting by a shareholder are in addition to, and not in
lieu of, the requirements set forth in Rule 14a-8 under Section 14 of the
Securities Exchange Act of 1934, as amended, or any successor provision.

        2.5.2  BUSINESS AT SPECIAL MEETINGS

        At any special meeting of the shareholders, only such business as is
specified in the notice of such special meeting given by or at the direction of
the person or persons calling such meeting, in accordance with subsection 2.4
hereof, shall come before such meeting.

        2.5.3  NOTICE TO CORPORATION

        Any written notice required to be delivered by a shareholder to the
corporation pursuant to subsection 2.4, subsection 2.5.1 or subsection 2.5.2
hereof must be given, either by personal delivery or by registered or certified
mail, postage prepaid, to the Secretary at the corporation's principal executive
offices. Any such shareholder notice shall set forth (i) the name and address of
the shareholder proposing such business; (ii) a representation that the
shareholder is entitled to vote at such meeting and a statement of the number of
shares of the 


                                     Page 2
<PAGE>   8

corporation which are beneficially owned by the shareholder; (iii) a
representation that the shareholder intends to appear in person or by proxy at
the meeting to propose such business; and (iv) as to each matter the shareholder
proposes to bring before the meeting, a brief description of the business
desired to be brought before the meeting, the reasons for conducting such
business at the meeting, the language of the proposal (if appropriate), and any
material interest of the shareholder in such business.

2.6     NOTICE OF MEETING

        Written notice stating the place, day and hour of the meeting and, in
the case of a special meeting, the purpose or purposes for which the meeting is
called shall be given by or at the direction of the Board, the Chairman of the
Board, the President or the Secretary to each shareholder entitled to notice of
or to vote at the meeting not less than 10 nor more than 60 days before the
meeting, except that notice of a meeting to act on an amendment to the Articles
of Incorporation, a plan of merger or share exchange, the sale, lease, exchange
or other disposition of all or substantially all of the corporation's assets
other than in the regular course of business or the dissolution of the
corporation shall be given not less than 20 nor more than 60 days before such
meeting. Such notice may be transmitted by mail, private carrier, personal
delivery, telegraph, teletype or communications equipment which transmits a
facsimile of the notice to like equipment which receives and reproduces such
notice. If these forms of written notice are impractical in the view of the
Board, the Chairman of the Board, the President or the Secretary, written notice
may be transmitted by an advertisement in a newspaper of general circulation in
the area of the corporation's principal office. If such notice is mailed, it
shall be deemed effective when deposited in the official government mail,
first-class postage prepaid, properly addressed to the shareholder at such
shareholder's address as it appears in the corporation's current record of
shareholders. Notice given in any other manner shall be deemed effective when
dispatched to the shareholder's address, telephone number or other number
appearing on the records of the corporation. Any notice given by publication as
herein provided shall be deemed effective five days after first publication.

2.7     WAIVER OF NOTICE

        Whenever any notice is required to be given to any shareholder under the
provisions of these Bylaws, the Articles of Incorporation or the Washington
Business Corporation Act, a waiver thereof in writing, signed by the person or
persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting, shall be deemed equivalent to the
giving of such notice. Further, notice of the time, place and purpose of any
meeting will be deemed to be waived by any shareholder by attendance thereat in
person or by proxy, unless such shareholder at the beginning of the meeting
objects to holding the meeting or transacting business at the meeting.

<PAGE>   9

2.8     FIXING OF RECORD DATE FOR DETERMINING SHAREHOLDERS

        For the purpose of determining shareholders entitled (a) to notice of or
to vote at any meeting of shareholders or any adjournment thereof, (b) to demand
a special meeting, or (c) to receive payment of any dividend, or in order to
make a determination of shareholders for any other purpose, the Board may fix a
future date as the record date for any such determination. Such record date
shall be not more than 70 days, and in case of a meeting of shareholders not
less than 10 days prior to the date on which the particular action requiring
such determination is to be taken. If no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting, the
record date shall be the day immediately preceding the date on which notice of
the meeting is first given to shareholders. Such a determination shall apply to
any adjournment of the meeting unless the Board fixes a new record date, which
it shall do if the meeting is adjourned to a date more than 120 days after the
date fixed for the original meeting. If no record date is set for the
determination of shareholders entitled to receive payment of any stock dividend
or distribution (other than one involving a purchase, redemption, or other
acquisition of the corporation's shares) the record date shall be the date the
Board authorizes the stock dividend or distribution.

2.9     VOTING RECORD

        At least 10 days before each meeting of shareholders, an alphabetical
list of the shareholders entitled to notice of such meeting shall be made,
arranged by voting group and by each class or series of shares therein, with the
address of and number of shares held by each shareholder. This record shall be
kept at the principal office of the corporation for 10 days prior to such
meeting, and shall be kept open at such meeting, for the inspection of any
shareholder or any shareholder's agent.

2.10    QUORUM

        A majority of the votes entitled to be cast on a matter by the holders
of shares that, pursuant to the Articles of Incorporation or the Washington
Business Corporation Act, are entitled to vote and be counted collectively upon
such matter, represented in person or by proxy, shall constitute a quorum of
such shares at a meeting of shareholders. If less than a majority of such votes
are represented at a meeting, a majority of the votes so represented may adjourn
the meeting from time to time without further notice if the new date, time or
place is announced at the meeting before adjournment. Any business may be
transacted at a reconvened meeting that might have been transacted at the
meeting as originally called, provided a quorum is present or represented
thereat. Once a share is represented for any purpose at a meeting other than
solely to object to holding the meeting or transacting business thereat, it is
deemed present for quorum purposes for the remainder of the meeting and any
adjournment thereof (unless a new record date is or must be set for the
adjourned meeting) notwithstanding the withdrawal of enough shareholders to
leave less than a quorum.



                                     Page 4
<PAGE>   10

2.11    MANNER OF ACTING

        If a quorum is present, action on a matter other than the election of
Directors shall be approved if the votes cast in favor of the action by the
shares entitled to vote and be counted collectively upon such matter exceed the
votes cast against such action by the shares entitled to vote and be counted
collectively thereon, unless the Articles of Incorporation or the Washington
Business Corporation Act requires a greater number of affirmative votes.

2.12    PROXIES

        A shareholder may vote by proxy executed in writing by the shareholder
or by his or her attorney-in-fact or agent. Such proxy shall be effective when
received by the Secretary or other officer or agent authorized to tabulate
votes. A proxy shall become invalid 11 months after the date of its execution,
unless otherwise provided in the proxy. A proxy with respect to a specified
meeting shall entitle the holder thereof to vote at any reconvened meeting
following adjournment of such meeting but shall not be valid after the final
adjournment thereof.

2.13    VOTING OF SHARES

        Except as provided in the Articles of Incorporation or in Section 2.13
hereof, each outstanding share entitled to vote with respect to a matter
submitted to a meeting of shareholders shall be entitled to one vote upon such
matter.

2.14    VOTING FOR DIRECTORS

        Each shareholder entitled to vote at an election of Directors may vote,
in person or by proxy, the number of shares owned by such shareholder for as
many persons as there are Directors to be elected and for whose election such
shareholder has a right to vote. Unless otherwise provided in the Articles of
Incorporation, the candidates elected shall be those receiving the largest
number of votes cast, up to the number of Directors to be elected.

2.15    ACTION BY SHAREHOLDERS WITHOUT A MEETING

        Any action which could be taken at a meeting of the shareholders may be
taken without a meeting if one or more written consents setting forth the action
so taken are signed by all shareholders entitled to vote on the action and are
delivered to the corporation. If not otherwise fixed by the Board, the record
date for determining shareholders entitled to take action without a meeting is
the date the first shareholder signs the consent. A shareholder may withdraw a
consent only by delivering a written notice of withdrawal to the corporation
prior to the time that all consents are in the possession of the corporation.
Action taken by written consent of shareholders without a meeting is effective
when all consents are in the possession of the corporation, unless the consent
specifies a later effective date. Any such consent shall be inserted in the
minute book as if it were the minutes of a meeting of the shareholders.

                          SECTION 3. BOARD OF DIRECTORS

3.1     GENERAL POWERS

        All corporate powers shall be exercised by or under the authority of,
and the business and affairs of the corporation shall be managed under the
direction of, the Board, except as may be otherwise provided in these Bylaws,
the Articles of Incorporation or the Washington Business Corporation Act.

3.2     NUMBER AND TENURE

        The Board shall be composed of not less than two nor more than seven
Directors, the specific number to be set by resolution of the Board. The number
of Directors may be changed from time to time by amendment to these Bylaws, but
no decrease in the number of Directors shall have the effect of shortening the
term of any incumbent Director.

        At the first election of Directors, whether at an annual meeting of
shareholders or otherwise (in either case, the "Next Director Election"), after
the closing of an initial public offering of equity securities of this
corporation pursuant to a registration statement filed with the Securities and
Exchange Commission under the Securities Act of 1933, as amended, the Board of
Directors shall be divided into three classes, with such classes to be as equal
in number as may be possible and with the designation or nomination of
individual Directors to such classes for election at such Next Director Election
being in the discretion of the Board of Directors. At the Next Director
Election, each Class 1 Director shall be elected to serve until the next ensuing
annual meeting of shareholders, each Class 2 Director shall be elected to serve
until the second ensuing annual meeting of shareholders and each Class 3
Director shall be elected to serve until the third ensuing annual meeting of
shareholders. At each annual meeting of shareholders following the Next Director
Election, a number of Directors equal to the number of Directors in the class
whose term expires at the time of such meeting shall be elected to serve for a
three year term expiring at the third ensuing annual meeting of shareholders;
provided, however, that, if necessary to maintain relative equality among the
classes of Directors due to vacancies or removals of Directors, Directors may be
elected to a class whose term expires prior to such third ensuing annual meeting
of shareholders. Notwithstanding any of the foregoing provisions of this

        Each person who was, is or is threatened to be made a named party to or
is otherwise involved (including, without limitation, as a witness) in any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative and whether 



                                    Page 18

formal or informal (hereinafter a "proceeding"), by reason of the fact that he
or she is or was a Director or officer of the corporation or, that being or
having been such a Director or officer or an employee of the corporation, he or
she is or was serving at the request of the corporation as a Director, officer,
partner, trustee, employee or agent of another corporation or of a partnership,
joint venture, trust, employee benefit plan or other enterprise (hereinafter an
"indemnitee"), whether the basis of a proceeding is alleged action in an
official capacity as such a Director, officer, partner, trustee, employee or
agent or in any other capacity while serving as such a Director, officer,
partner, trustee, employee or agent, shall be indemnified and held harmless by
the corporation against all expense, liability and loss (including counsel fees,
judgments, fines, ERISA excise taxes or penalties and amounts to be paid in
settlement) actually and reasonably incurred or suffered by such indemnitee in
connection therewith, and such indemnification shall continue as to an
indemnitee who has ceased to be a Director, officer, partner, trustee, employee
or agent and shall inure to the benefit of the indemnitee's heirs, executors and
administrators. Except as provided in subsection 10.2 of this Section with
respect to proceedings seeking to enforce rights to indemnification, the
corporation shall indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by such indemnitee only if a proceeding (or part
thereof) was authorized or ratified by the Board. The right to indemnification
conferred in this Section shall be a contract right.

10.2    RESTRICTIONS ON INDEMNIFICATION

        No indemnification shall be provided to any such indemnitee for acts or
omissions of the indemnitee finally adjudged to be intentional misconduct or a
knowing violation of law, for conduct of the indemnitee finally adjudged to be
in violation of Section 23B.08.310 of the Washington Business Corporation Act,
for any transaction with respect to which it was finally adjudged that such
indemnitee personally received a benefit in money, property or services to which
the indemnitee was not legally entitled or if the corporation is otherwise
prohibited by applicable law from paying such indemnification, except that if
Section 23B.08.560 or any successor provision of the Washington Business
Corporation Act is hereafter amended, the restrictions on indemnification set
forth in this subsection 10.2 shall be as set forth in such amended statutory
provision.

10.3    ADVANCEMENT OF EXPENSES

        The right to indemnification conferred in this Section shall include the
right to be paid by the corporation the expenses incurred in defending any
proceeding in advance of its final disposition (hereinafter an "advancement of
expenses"). An advancement of expenses shall be made upon delivery to the
corporation of an undertaking (hereinafter an "undertaking"), by or on behalf of
such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal that such indemnitee is not entitled to be indemnified for such expenses
under this subsection 10.3.

10.4    RIGHT OF INDEMNITEE TO BRING SUIT

        If a claim under subsection 10.1 or 10.3 of this Section is not paid in
full by the corporation within 60 days after a written claim has been received
by the corporation, except in the case of a claim for an advancement of
expenses, in which case the applicable period shall be 20 days, the indemnitee
may at any time thereafter bring suit against the corporation to recover the
unpaid amount of the claim. If successful in whole or in part, in any such suit
or in a suit brought by the corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the indemnitee shall be entitled to be
paid also the expense of prosecuting or defending such suit. The indemnitee
shall be presumed to be entitled to indemnification under this Section upon
submission of a written claim (and, in an action brought to enforce a claim for
an advancement of expenses, where the required undertaking has been tendered to
the corporation) and thereafter the corporation shall have the burden of proof
to overcome the presumption that the indemnitee is so entitled.

10.5    PROCEDURES EXCLUSIVE

        Pursuant to Section 23B.08.560(2) or any successor provision of the
Washington Business Corporation Act, the procedures for indemnification and
advancement of expenses set forth in this Section are in lieu of the procedures
required by Section 23B.08.550 or any successor provision of the Washington
Business Corporation Act.

10.6    NONEXCLUSIVITY OF RIGHTS

        The right to indemnification and the advancement of expenses 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 Articles of
Incorporation or Bylaws of the corporation, general or specific action of the
Board, contract or otherwise.

10.7    INSURANCE, CONTRACTS AND FUNDING

        The corporation may maintain insurance, at its expense, to protect
itself and any Director, officer, partner, trustee, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any 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 Washington Business Corporation Act. The corporation
may enter into contracts with any Director, officer, partner, trustee, employee
or agent of the corporation in furtherance of the provisions of this Section and
may create a trust fund, grant a security interest or use other means
(including, without limitation, a letter of credit) to ensure the payment of
such amounts as may be necessary to effect indemnification as provided in this
Section.

        The corporation may, by action of the Board, grant rights to
indemnification and advancement of expenses to employees and agents or any class
or group of employees and agents of the corporation (i) with the same scope and
effect as the provisions of this Section with respect to the indemnification and
advancement of expenses of Directors and officers of the corporation; (ii)
pursuant to rights granted pursuant to, or provided by, the Washington Business
Corporation Act; or (iii) as are otherwise consistent with law.

or domestic corporation of which a majority of the shares entitled to vote in
the election of its Directors is held by the corporation or (b) as a partner,
trustee or otherwise in an executive or management capacity in a partnership,
joint venture, trust or other enterprise of which the corporation or a wholly
owned subsidiary of the corporation is a general partner or has a majority
ownership shall be deemed to be so serving at the request of an executive
officer of the corporation and entitled to indemnification and advancement of
expenses under subsections 10.1 and 10.3 of this Section.

                             SECTION 11. AMENDMENTS

adopted by the Board, except that the Board may not repeal or amend any Bylaw
that the shareholders have expressly provided, in amending or repealing such
Bylaw, may not be amended or repealed by the Board. The shareholders may also
alter, amend and repeal these Bylaws or adopt new Bylaws. All Bylaws made by the
Board may be amended, repealed, altered or modified by the shareholders.

                SECTION 12. VOTING SHARES OF ANOTHER CORPORATION

        Shares of another corporation held by this corporation may be voted by
the president or vice-president, or by proxy appointment form executed by either
