                                  ARTICLE I

                                   Offices

          Section 1. PRINCIPAL EXECUTIVE OFFICE. The principal executive
office of the corporation is hereby fixed and located at 9999 Willow Creek
Road, San Diego, California 92131. The Board of Directors is hereby granted
full power and authority to change the principal executive office from one
location to another. Any such change shall be noted on the Bylaws by the
secretary, opposite this section, or this section may be amended to state the
new location.

          Section 2. OTHER OFFICES. Other business offices may at any time be
established by the Board of Directors at any place or places where the
corporation is qualified to do business.

                                  ARTICLE II

                           Meetings of Shareholders

          Section 1. PLACE OF MEETINGS. All annual or other meetings of
shareholders shall be held at the principal executive office of the
corporation, or at any other place within or without the State of California
which may be designated by the Board of Directors.

          Section 2. ANNUAL MEETINGS. The annual meetings of shareholders
shall be held on such dates and at such times as shall be designated by the
Board of Directors and stated in the notice of the meeting given to each
shareholder as provided below. At such meetings, directors shall be elected,
reports of the affairs of the corporation shall be considered, and any other
business may be transacted which is within the powers of the shareholders.
Written notice of each annual meeting shall be given to each shareholder
entitled to vote, either personally or by mail or other means of written
communication, charges prepaid, addressed to such shareholder at its address
appearing on the books of the corporation or given to the corporation for the
purpose of notice. If any notice or report addressed to the shareholder at
the address of such shareholder appearing on the books of the corporation is
returned to the corporation by the United States Postal Service marked to
indicate that the United States Postal Service is unable to deliver the
notice or report to the shareholder at such address, all future notices or
reports shall be deemed to have been duly given without further mailing if
the same shall be available for the shareholder upon written demand of the
shareholder at the principal executive office of the corporation for a period
of one year from the date of the giving of the notice or report to all other
shareholders. If a shareholder gives no address, notice shall be deemed to
have been given if sent by mail or other means of written communication
addressed to the place where the principal executive office of the
corporation is situated, or if published at least once in some newspaper of
general circulation in the county in which the principal executive office is
located.




          All such notices shall be given to each shareholder entitled
thereto not less than ten (10) days nor more than sixty (60) days before each
annual meeting. Any such notice shall be deemed to have been given at the
time when delivered personally or deposited in the mail or sent by other
means of written communication. An affidavit of mailing of any such notice in
accordance with the foregoing provisions, executed by the secretary,
assistant secretary or any transfer agent of the corporation, shall be prima
facie evidence of the giving of the notice.

          Such notices shall specify:

               (a)  the place, the date, and the hour of such meeting;

               (b)  those matters which the Board, at the time of the mailing
     of the notice, intends to present for action by the shareholders at the
     meeting;

               (c)  if directors are to be elected, the names of nominees
     intended at the time of the notice to be presented by management for
     election;

               (d)  the general nature of a proposal, if any, to take action
     with respect to approval of (i) a contract or other transaction with an
     interested director, (ii) amendment of the Articles of Incorporation,
     (iii) a reorganization of the corporation as defined in Section 181 of
     the California General Corporation Law, (iv) voluntary dissolution of
     the corporation, or (v) a distribution in dissolution other than in
     accordance with the rights of outstanding preferred shares, if any; and

               (e)  such other matters, if any, as may be expressly required
     by statute.

          Section 3. SPECIAL MEETINGS. Special meetings of the shareholders
for the purpose of taking any action permitted by the shareholders under the
General Corporation Law and the Articles of Incorporation of this
corporation, may be called at any time only by the Board of Directors, the
Chairman of the Board, the Chief Executive Officer or the President, or by
one or more shareholders entitled to cast not less than ten percent (10%) of
the votes at the meeting. Upon request in writing that a special meeting of
shareholders be called for any proper purpose, directed to the chairman of
the Board, president, vice president or secretary by any person (other than
the Board) entitled to call a special meeting of shareholders, the officer
forthwith shall cause notice to be given to shareholders entitled to vote
that a meeting will be held at a time requested by the person or persons
calling the meeting, not less than thirty-five (35) nor more than sixty (60)
days after receipt of the request. Except in special cases where other
express provision is made by statute, notice of such special meetings shall
be given in the same manner as for the annual meeting of shareholders. In
addition to the matters required by items (a) and, if applicable, (c) of the
preceding Section, notice of any special meeting shall specify the general
nature of the business to be transacted, and no other business may be
transacted at such meeting.

          Section 4. QUORUM. The presence in person or by proxy of the persons
entitled to vote a majority of the shares at any meeting shall constitute a
quorum for the transaction of business at that meeting. The shareholders present
at a duly called or held meeting at which a quorum is present may continue to do
business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.


                                       2



          Section 5. ADJOURNED MEETING AND NOTICE THEREOF. Any shareholders'
meeting, annual or special, whether or not a quorum is present, may be
adjourned from time to time by the vote of a majority of the shares, the
holders of which are either present in person or by proxy thereat, but in the
absence of a quorum no other business may be transacted at such meeting,
except as provided in Section 4 above. When any shareholders' meeting, either
annual or special, is adjourned for forty-five days or more, or if after
adjournment a new record date is fixed for the adjourned meeting, notice of
the adjourned meeting shall be given as in the case of an original meeting.
Except as provided above, it shall not be necessary to give any notice of the
time and place of the adjourned meeting or of the business to be transacted
thereat, other than by announcement of the time and place of the adjourned
meeting at the meeting at which the adjournment is taken.

          Section 6. VOTING. Unless a record date for voting purposes be
fixed as provided in Section 1 of Article V of these Bylaws, then, subject to
the provisions of Sections 702 and 704, inclusive, of the Corporations Code
of California (relating to voting of shares held by a fiduciary, in the name
of a corporation, or in joint ownership) only persons in whose names shares
entitled to vote stand on the stock records of the corporation at the close
of business on the business day next preceding the day on which notice of the
meeting is given or if such notice is waived, at the close of business on the
business day next preceding the day on which the meeting of shareholders is
held, shall be entitled to vote at such meeting, and such day shall be the
record date for such meeting. Such vote may be viva voce or by ballot;
provided, however, that all elections for directors must be by ballot upon
demand made by a shareholder at any election and before the voting begins. If
a quorum is present, except with respect to election of directors, the
affirmative vote of the majority of the shares represented at the meeting and
entitled to vote on any matter shall be the act of the shareholders, unless
the vote of a greater number or voting by classes is required by the General
Corporation Law or the Articles of Incorporation.

          Section 7. NO CUMULATIVE VOTING. No holder of any class of stock of
this corporation shall be entitled to cumulate votes at any election of
directors of this corporation. This provision shall become effective only
when this corporation becomes a listed corporation within the meaning of
Section 301.5 of the California General Corporation Law.

          Section 8. VALIDATION OF DEFECTIVE CALLED OR NOTICED MEETINGS. The
transactions of any meeting of shareholders, either annual or special,
however called and noticed, shall be as valid as though had at a meeting duly
held after regular call and notice, if a quorum be present either in person
or by proxy, and if, whether before or after the meeting, each of the persons
entitled to vote, not present in person or by proxy, or who, though present,
has, at the beginning of the meeting, properly objected to the transaction of
any business thereat because the meeting was not lawfully called or convened,
or to particular matters of business legally required to be included in the
notice, but not so included, signs a written waiver of notice, or a consent
to the holding of such meeting, or an approval of the minutes thereof. All
such waivers, consents or approvals shall be filed with the corporate records
or made a part of the minutes of the meeting.

          Section 9. PROXIES. Every person entitled to vote shall have the
right to do so whether in person or by one or more agents authorized by a
written proxy executed by such person or such person's duly authorized agent
and filed with the secretary of the corporation. Any proxy duly executed is
not revoked and continues in full force and effect until (i) an


                                       3



instrument revoking it or a duly executed proxy bearing a later date is filed
with the secretary of the corporation prior to the vote pursuant thereto, (ii)
the person executing the proxy attends the meeting and votes in person, or (iii)
written notice of the death or incapacity of the maker of the proxy is received
by the corporation before the vote pursuant thereto is counted; provided that no
proxy shall be valid after the expiration of eleven (11) months from the date of
its execution, unless the person executing it specifies therein the length of
time for which such proxy is to continue in force.

          Section 10. INSPECTORS OF ELECTION. In advance of any meeting of
shareholders, the Board of Directors may appoint any person other than nominees
for office as inspectors of election to act at such meeting or any adjournment
thereof. If inspectors of election be not so appointed, the chairman of any such
meeting may, on the request of any shareholder or its proxy, shall make such
appointment at the meeting. The number of inspectors shall be either one or
three. If appointed at a meeting on the request of one or more shareholders or
proxies, the majority of shares represented in person or by proxy shall
determine whether one or three inspectors are to be appointed. In case any
person appointed as inspector fails to appear or fails or refuses to act, the
vacancy may, and on the request of any shareholder or a shareholder's proxy
shall, be filled by appointment by the Board of Directors in advance of the
meeting, or at the meeting by the chairman of the meeting.

          The duties of such inspectors shall be as prescribed by Section 707
of the General Corporation Law and shall include determining the number of
shares outstanding and the voting power of each, the shares represented at
the meeting, the existence of a quorum, the authenticity, validity and effect
of proxies; receiving votes or ballots; hearing and determining all
challenges and questions in any way arising in connection with the right to
vote; counting and tabulating all votes; determining when the polls close;
determining the result; and such acts as may be proper to conduct the
election or vote with fairness to all shareholders. In the determination of
the validity and effect of proxies, the dates contained on the forms of proxy
shall presumptively determine the order of execution of the proxies,
regardless of the postmark dates on the envelopes in which they are mailed.

          The inspectors of election shall perform their duties impartially,
in good faith, to the best of their ability and as expeditiously as is
practical. If there be three inspectors of election, the decision, act or
certificate of a majority is effective in all respects as the decision, act
or certificate of all. Any report or certificate made by the inspectors of
election is prima facie evidence of the facts stated therein.

          Section 11. NOTICE OF BUSINESS. At any meeting of shareholders,
only such business shall be conducted as shall have been brought before the
meeting (a) by or at the direction of the Board of Directors, (b) in
accordance with Rule 14a-8 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or (c) by any shareholder of the corporation
who was a shareholder of record at the time of giving of notice provided for
in this bylaw, who is entitled to vote at the meeting and who complies with
the notice procedures set forth in this bylaw. For business to be properly
brought before a meeting by a shareholder pursuant to clause (c) of this
bylaw, the shareholder must have given timely notice thereof in writing to
the Secretary of the corporation and such other business must otherwise be a
proper matter for shareholder action. To be timely, a shareholder's notice
shall be delivered to the


                                       4



Secretary at the principal executive offices of the Corporation not later
than the close of business on the 60th day nor earlier than the close of
business on the 90th day prior to the meeting; PROVIDED, HOWEVER, that if less
than 70 days' notice of the date of the meeting is given by the corporation,
notice by the shareholder to be timely must be so delivered no later than the
10th day following the day on which public announcement of the date of such
meeting is first made by the corporation. In no event shall the public
announcement of an adjournment of a meeting commence a new time period for
the giving of a shareholder's notice as described above. Such shareholder's
notice shall set forth (i) as to any business that 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 and any material interest in such business of such shareholder
and the beneficial owner, if any, on whose behalf the proposal is made; and
(ii) as to the shareholder giving the notice and the beneficial owner, if
any, on whose behalf the proposal is made (x) the name and address of such
shareholder, as they appear on the corporation's books, and of such
beneficial owner and (y) the class and number of shares of stock of the
corporation which are owned beneficially and of record by such shareholder
and such beneficial owner. If notice has not been given pursuant to this
Section, the chairman of the meeting may declare to the meeting that the
proposed business was not properly brought before the meeting, and such
business may not be transacted at the meeting. The foregoing provisions of
this Section do not relieve any shareholder of any obligation to comply with
all applicable requirements of the Exchange Act and rules and regulations
thereunder. For purposes of these bylaws, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document
publicly filed by the corporation with the Securities and Exchange Commission
pursuant to Section 13, 14 or 15(d) of the Exchange Act.

          Section 12. NOMINATION OF DIRECTORS. At any meeting of
shareholders, a person may be a candidate for election to the Board only if
such person is nominated (a) by or at the direction of the Board, (b) by any
nominating committee or person appointed by the Board, or (c) by a
shareholder of record entitled to vote at such meeting who complies with the
notice procedures set forth in this Section and has given timely notice of
such nomination in writing to the Secretary of the corporation. To be timely,
a shareholder's notice shall be delivered to the Secretary at the principal
executive offices of the corporation not later than the close of business on
the 60th day nor earlier than the close of business on the 90th day prior to
the meeting; PROVIDED, HOWEVER, that if less than 70 days notice of the date
of the meeting is given by the corporation, notice by the shareholder to be
timely must be so delivered no later than the 10th day following the day on
which public announcement of the date of such meeting is first made by the
corporation. In no event shall the public announcement of an adjournment of
an annual meeting commence a new time period for the giving of a
shareholder's notice as described above. Such shareholder's notice shall set
forth as to each person whom the shareholder proposes to nominate for
election or reelection as a director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
directors in an election contest, or is otherwise required, in each case
pursuant to Regulation 14A under the Exchange Act and Rule 14a-11
thereunder (including such person's written consent to being named in the
proxy statement as a nominee and to serving as a director if elected). The
corporation may require such other information to be furnished respecting any
proposed nominee as may be reasonably necessary to determine whether the
proposed nominee has, or represents, interests which are opposed to or in
conflict with the interests of the corporation. No person


                                       5



shall be eligible for election as a director at any meeting unless nominated in
accordance with this Section.

                                 ARTICLE III

                                  Directors

          Section 1. POWERS. Subject to limitations of the Articles of
Incorporation and the California General Corporation Law as to action to be
authorized or approved by the shareholders, and subject to the duties of
directors as prescribed by these Bylaws, all corporate powers shall be
exercised by or under the authority of, and the business and affairs of the
corporation shall be controlled by, the Board of Directors. Without prejudice
to such general powers, but subject to the same limitations, it is hereby
expressly declared that the directors shall have the following powers, to wit:

          FIRST - To select and remove all the officers, agents and employees
of the corporation, prescribe such powers and duties for them as may not be
inconsistent with law, with the Articles of Incorporation or these Bylaws,
fix their compensation and require from them security for faithful service.

          SECOND - To conduct, manage and control the affairs and business of
the corporation, and to make such rules and regulations therefor not
inconsistent with law, or with the Articles of Incorporation or these Bylaws,
as they may deem best.

          THIRD - To change the principal executive office and principal
office for the transaction of business of the corporation from one location
to another as provided in Article I, Section 1, hereof; to fix and locate
from time to time one or more subsidiary offices of the corporation within or
without the State of California, as provided in Article I, Section 2, hereof;
to designate any place within or without the State of California for the
holding of any shareholders' meeting or meetings; and to adopt, make and use
a corporate seal, and to prescribe the forms of certificates of stock, and to
alter the form of such seal and of such certificates from time to time, as in
their judgment they may deem best, provided such seal and such certificates
shall at all times comply with the provisions of law.

          FOURTH - To authorize the issue of shares of stock of the
corporation from time to time, upon such terms as may be lawful.

          FIFTH - To borrow money and incur indebtedness for the purposes of
the corporation, and to cause to be executed and delivered therefor, in the
corporate name, promissory notes, bonds, debentures, deeds of trust,
mortgages, pledges, hypothecations or other evidences of debt and securities
therefor.

          SIXTH - By resolution adopted by a majority of the authorized
number of directors, to designate an executive and other committees, each
consisting of two or more directors, to serve at the pleasure of the Board,
and to prescribe the manner in which proceedings of such committees shall be
conducted. Unless the Board of Directors shall otherwise prescribe the manner
of proceedings of any such committee, meetings of such committee may be
regularly scheduled in advance and may be called at any time by any two
members thereof; otherwise, the


                                       6



provisions of these Bylaws with respect to notice and conduct of meetings of the
Board shall govern. Any such committee, to the extent provided in a resolution
of the Board, shall have all of the authority of the Board, except with respect
to:

          (i)   the approval of any action for which the General Corporation Law
          or the Articles of Incorporation also require shareholder approval;

          (ii)  the filling of vacancies on the Board or in any committee;

          (iii) the fixing of compensation of the directors for serving on the
          Board or on any committee;

          (iv)  the adoption, amendment or repeal of bylaws;

          (v)   the amendment or repeal of any resolution of the Board;

          (vi)  any distribution to the shareholders, except at a rate or in a
          periodic amount or within a price range determined by the Board;

          (vii) the appointment of other committees of the Board or the members
          thereof.

          Section 2. NUMBER AND QUALIFICATION OF DIRECTORS. The authorized
number of directors shall be not less than five (5) nor more than nine (9)
until changed by Amendment of the Articles of Incorporation or by a Bylaw
duly adopted by approval of the outstanding shares. The exact number of
directors shall be fixed, within the limits specified, by amendment of the
next sentence duly adopted either by the Board of Directors or the
shareholders. The exact number of directors shall be seven (7) until changed
as provided in this Section 2.

          Section 3. ELECTION AND TERM OF OFFICE. This section shall become
effective only when this corporation becomes a listed corporation within the
meaning of Section 301.5 of the California General Corporation Law.

          In the event that the authorized number of directors shall be fixed
with at least six (6) but less than nine (9) directors, the Board of
Directors shall be divided into two classes, designated Class I and Class II,
effective as of the first annual meeting following the effective date of this
Bylaw (the "Initial Annual Meeting"). Each class shall consist of one-half of
the directors or as close an approximation as possible. The initial term of
office of the directors of Class I shall expire at the annual meeting to be
held during the fiscal year following the Initial Annual Meeting, and the
initial term of office of the directors of Class II shall expire at the
annual meeting to be held during the second fiscal year following the Initial
Annual Meeting. At each annual meeting, commencing with the first annual
meeting following the Initial Annual Meeting, each of the successors to the
directors of the class whose term shall have expired at such annual meeting
shall be elected for a term running until the second annual meeting next
succeeding his or her election and until his or her successor shall have been
duly elected and qualified.

          In the event that the authorized number of directors shall be fixed
at nine (9) or more, the Board of Directors shall be divided into three
classes, designated Class I, Class II and


                                       7



Class III, effective as of the first annual meeting coinciding with or following
the division into three classes (the "Effective Date"). Each class shall consist
of one-third of the directors or as close an approximation as possible. The
initial term of office of the directors of Class I shall expire at the annual
meeting to be held during the first fiscal year following the Effective Date,
the initial term of office of the directors of Class II shall expire at the
annual meeting to be held during second fiscal year following the Effective Date
and the initial term of office of the directors of Class III shall expire at the
annual meeting to be held during the third fiscal year following the Effective
Date. At each annual meeting, commencing with the first annual meeting following
the Effective Date, each of the successors to the directors of the class whose
term shall have expired at such annual meeting shall be elected for a term
running until the third annual meeting next succeeding his or her election and
until his or her successor shall have been duly elected qualified.

          Notwithstanding the rule that the classes shall be as nearly equal in
number of directors as possible, in the event of any change in the authorized
number of directors, each director then continuing to serve as such shall
nevertheless continue as a director of the class of which he or she is a member
until the expiration of his or her current term, or his or her prior death,
resignation or removal.

          At each annual election, the directors chosen to succeed those
whose terms then expire shall be of the same class as the directors they
succeed, unless, by reason of any intervening changes in the authorized
number of directors, the Board of Directors shall designate one or more
directorships whose term then expires as directorships of another class in
order more nearly to achieve equality of number of directors among the
classes.

          This section only may be amended or repealed by the approval of the
Board of Directors and the outstanding shares (as defined in Section 152 of
the California General Corporation Law) voting as a single class,
notwithstanding Section 903 of the California General Corporation Law.

          Section 4. VACANCIES. A vacancy in the Board of Directors shall be
deemed to exist in the case of the death, resignation or removal of any
director, if a director has been declared of unsound mind by order of court
or convicted of a felony, if the authorized number of directors be increased,
or if the shareholders fail, at any annual or special meeting of shareholders
at which any director or directors are elected, to elect the full authorized
number of directors to be voted for at that meeting. No reduction of the
authorized number of directors shall have the effect of removing any director
prior to the expiration of his or her term of office.

          Subject to any provision contained in the Articles of
Incorporation, vacancies in the Board of Directors, except for a vacancy
created by the removal of a director, may be filled by a majority of the
remaining directors, though less than a quorum, or by a sole remaining
director; and each director so elected shall hold office until his or her
successor is elected at an annual or special meeting of the shareholders.
Subject to any provision contained in the Articles of Incorporation, a
vacancy in the Board of Directors created by the removal of a director may
only be filled by the vote of a majority of the shares entitled to vote
represented at a duly held meeting at which a quorum is present.


                                       8



          Subject to any provision contained in the Articles of Incorporation,
the shareholders may elect a director or directors at any time to fill any
vacancy or vacancies not filled by the directors. Any such election shall
require the vote of a majority of the shares entitled to vote represented at
a duly held meeting at which a quorum is present.

          Any director may resign effective upon giving written notice to the
chairman of the Board, the president, the secretary of the Board or the Board
of Directors of the corporation, unless the notice specifies a later time for
the effectiveness of such resignation. If the Board of Directors accepts the
resignation of a director tendered to take effect at a future time, the Board
or, subject to any provision contained in the Articles of Incorporation, the
shareholders shall have the power to elect a successor to take office when
the resignation is to become effective.

          Section 5. PLACE OF MEETING. Regular meetings of the Board of
Directors shall be held at any place within or without the State of
California which has been designated from time to time by resolution of the
Board or by written consent of all members of the Board. In the absence of
such designation, regular meetings shall be hold at the principal executive
office of the corporation. Special meetings of the Board may be held either
at a place so designated or at the principal executive office of the
corporation.

          Section 6. ORGANIZATION MEETING. Immediately following each annual
meeting of shareholders, the Board of Directors shall hold a regular meeting
at the place of said annual meeting or at such other place as shall be fixed
by the Board, for the purpose of organization of the newly elected Board,
election of officers, and the transaction of other business. Call and notice
of such meetings are hereby dispensed with.

          Section 7. OTHER REGULAR MEETINGS. Other regular meetings of the
Board of Directors shall be hold without call as provided in a resolution
adopted by the Board from time to time; provided, however, should said day
fall upon a legal holiday, then said meeting shall be held at the same time
on the next day thereafter ensuing which is a full business day. Notice of
all such regular meetings of the Board of Directors is hereby dispensed with.

          Section 8. SPECIAL MEETINGS. Special meetings of the Board of
Directors for any purpose or purposes may be called at any time by the
chairman of the Board, the president, any vice president or the secretary, or
by any two directors, or by one or more shareholders holding not less than
25% of any series of Preferred Stock of the corporation.

          Written notice of the time and place of special meetings shall be
delivered personally to each director or communicated to each director by
telephone or by telegraph or mail, charges prepaid, addressed to him or her
at his or her address as it is shown upon the records of the corporation or,
if it is not so shown on such records or is not readily ascertainable, at the
place at which meetings of the directors are regularly held. In case such
notice is mailed or telegraphed, it shall be deposited in the United States

be so delivered at least twenty-four (24) hours prior to the time of the
holding of the meeting. Such mailing,


                                       9



telegraphing or delivery, personally or by telephone, as above provided, shall
be due, legal and personal notice to each such director.

          Section 9. ACTION WITHOUT A MEETING. Any action by the Board of
Directors may be taken without a meeting if all members of the Board shall
individually or collectively consent in writing to such action. Such written
consent or consents shall be filed with the minutes of the proceedings of the
Board and shall have the same force and effect as a unanimous vote of such
directors at a meeting duly called and held.

          Section 10. ACTION AT A MEETING: QUORUM AND REQUIRED VOTE. Presence
of a majority of the authorized number of directors at a meeting of the Board
of Directors constitutes a quorum for the transaction of business, except as
hereinafter provided. Members of the Board may participate in a meeting
through use of conference telephone or similar communications equipment, so
long as all members participating in such meeting can hear one another.
Participation in a meeting as permitted in the preceding sentence constitutes
presence in person at such meeting.

          Every act or decision done or made by a majority of the directors
at a meeting duly hold at which a quorum is present shall be regarded as the
act of the Board of Directors, unless a greater number, or the same number
after disqualifying one or more directors from voting, is required by law, by
the Articles of Incorporation, or by these Bylaws. A meeting at which a
quorum is initially present may continue to transact business notwithstanding
the withdrawal of directors, provided that any action taken is approved by at
least a majority of the required quorum for such meeting.

          Section 11. VALIDATION OF DEFECTIVELY CALLED OR NOTICED MEETINGS.
The transactions of any meeting of the Board of Directors, however called or
noticed or wherever held, shall be as valid as though had at a meeting duly
held after regular call and notice, if a quorum is present and if, either
before or after the meeting, each of the directors not present or who, though
present, has, prior to the meeting or at its commencement, protested the lack
of proper notice, signs a written waiver of notice or a consent to holding
such meeting or an approval of the minutes thereof. All such waivers,
consents or approvals shall be filed with the corporate records or made a
part of the minutes of the meeting.

          Section 12. ADJOURNMENT. A quorum of the directors may adjourn any
directors' meeting to meet again at a stated day and hour; provided, however,
that in the absence of a quorum a majority of the directors present at any
directors' meeting, either regular or special, may adjourn from time to time
until the time fixed for the next regular meeting of the Board.

          Section 13. NOTICE OF ADJOURNMENT. If the meeting is adjourned for
more than twenty-four (24) hours, notice of any adjournment to another time
or place shall be given prior to the time of the adjourned meeting to the
directors who were not present at the time of adjournment. Otherwise, notice
of the time and place of holding an adjourned meeting need not be given to
absent directors if the time and place be fixed at the meeting adjourned.

          Section 14. FEES AND COMPENSATION. Directors and members of
committees may receive such compensation, if any, for their services, and

of the Board of Directors.

          Section 15. INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND
OTHER AGENTS.

          (a)   INDEMNIFICATION OF DIRECTORS AND OFFICERS. Each person who
          was or is a party or is threatened to be made a party to or is
          involved in any threatened, pending or completed action, suit or
          proceeding, formal or informal, whether brought in the name of the
          corporation or otherwise and whether of a civil, criminal,
          administrative or investigative nature (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 an alleged
          action or inaction in an official capacity or in any other capacity
          while serving as a director or officer, shall, subject to the terms
          of any agreement between the corporation and such person, be
          indemnified and held harmless by the corporation to the fullest
          extent permissible under California law and the corporation's
          Articles of Incorporation, against all costs, charges, expenses,
          liabilities and losses (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 or officer and shall
          inure to the benefit of his or her heirs, executors and
          administrators; provided, however, that (a) 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
          the corporation, (b) the corporation shall indemnify any such
          person seeking indemnification in connection with a proceeding (or
          part thereof) other than a proceeding by or in the name of the
          corporation to procure a judgment in its favor only if any
          settlement of such a proceeding is approved in writing by the
          corporation, (c) no such person shall be indemnified (i) except to
          the extent that the aggregate of losses to be indemnified exceeds
          the amount of such losses for which the director or officer is paid
          pursuant to any directors' and officers' liability insurance policy
          maintained by the corporation; (ii) on account of any suit in which
          judgment is rendered against such person for an accounting of
          profits made from the purchase or sale by such person of securities
          of the corporation pursuant to the provisions of Section 16(b) of
          the Securities Exchange Act of 1934 and amendments thereto or
          similar provisions of any federal state or local statutory law;
          (iii) if a court of competent jurisdiction finally determines that
          any indemnification hereunder is unlawful; and (iv) as to
          circumstances in which indemnity is expressly prohibited by the
          Law, and (d) no such person shall be indemnified with regard to any
          action brought by or in the right of the corporation for breach of
          duty to the corporation and its shareholders (i) for acts or
          omissions involving intentional misconduct or knowing and culpable
          violation of law; (ii)


                                      11



          for acts or omissions that the director or officer believes to be
          contrary to the best interests of the corporation or its
          shareholders or that involve the absence of good faith on the part
          of the director or officer; (iii) for any transaction from which
          the director or officer derived an improper personal benefit; (iv)
          for acts or omissions that show a reckless disregard for the
          director's or officer's duty to the corporation or its shareholders
          in circumstances in which the director or officer was aware, or
          should have been aware, in the ordinary course of performing his or
          her duties, of a risk of serious injury to the corporation or its
          shareholders; (v) for acts or omissions that constitute an
          unexcused pattern of inattention that amounts to an abdication of
          the director's or officer's duties to the corporation or its
          shareholders; and (vi) for costs, charges, expenses, liabilities
          and losses arising under Section 310 or 316 of the General
          Corporation Law of California (the "Law"). The right to
          indemnification conferred in this Section 15 shall be a contract
          right and shall include the right to be paid by the corporation
          expenses incurred in defending any proceeding in advance of its
          final disposition; provided, however, that if the Law permits 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, such advances 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 to the corporation if it shall be
          ultimately determined that such person is not entitled to be
          indemnified.

          (b)   INDEMNIFICATION OF EMPLOYEES AND AGENTS. A person who was or
          is a party or is threatened to be made a party to or is involved in
          any proceeding by reason of the fact that he or she is or was an
          employee or agent of the corporation or is or was serving at the
          request of the corporation as an employee or agent of another
          enterprise, including service with respect to employee benefit
          plans, whether the basis of such action is an alleged action or
          inaction in an official capacity or in any other capacity while
          serving as an employee or agent, may, subject to the terms of any
          agreement between the corporation and such person, be indemnified
          and held harmless by the corporation to the fullest extent
          permitted by California law and the corporation's Articles of
          Incorporation, against all costs, charges, expenses, liabilities
          and losses (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. The immediately preceding sentence is not
          intended to be and shall not be considered to confer a contract
          right on any employee or agent (other than directors and officers)
          of the corporation.

          (c)   RIGHT OF DIRECTORS AND OFFICERS TO BRING SUIT. If a claim
          under Paragraph (a) of this Section 15 is not paid in full by the
          corporation within 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
          also be entitled to be paid the expense of prosecuting such claim.
          Neither the failure of the


                                      12



          corporation (including its Board of Directors, independent legal
          counsel, or its shareholders) to have made a determination prior to
          the commencement of such action that indemnification of the
          claimant is permissible in the circumstances because he or she has
          met the applicable standard of conduct, if any, nor an actual
          determination by the corporation (including its Board of Directors,
          independent legal counsel, or its shareholders) that the claimant
          has not met the applicable standard of conduct, shall be a defense
          to the action or create a presumption for the purpose of an action
          that the claimant has not met the applicable standard of conduct.

          (d)   SUCCESSFUL DEFENSE. Notwithstanding any other provision of
          this Section 15, to the extent that a director or officer has been
          successful on the merits or otherwise (including the dismissal of
          an action without prejudice or the settlement of a proceeding or
          action without admission of liability) in defense of any proceeding
          referred to in paragraph (a) of this Section 15 or in defense of
          any claim, issue or matter therein, he or she shall be indemnified
          against expenses (including attorneys' fees) actually and
          reasonably incurred in connection therewith.

          (e)   NON-EXCLUSIVITY OF RIGHTS. The right to indemnification
          provided by this Section 15 shall not be exclusive of any other
          right which any person may have or hereafter acquire under any
          statute, bylaw, agreement, vote of shareholders or disinterested
          directors or otherwise.

          (f)   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 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 Law.

          (g)   EXPENSES AS A WITNESS. To the extent that any director or
          officer of the corporation is by reason of such position, or a
          position with another entity at the request of the corporation, a
          witness in any action, suit or proceeding, he or she shall be
          indemnified against all costs and expenses actually and reasonably
          incurred by him or her on his or her behalf in connection
          therewith.

          (h)   INDEMNITY AGREEMENTS. The corporation may enter into
          agreements with any director, officer, employee or agent of the
          corporation providing for indemnification to the fullest extent
          permissible under the Law and the corporation's Articles of
          Incorporation.

          (i)   SEPARABILITY. Each and every paragraph, sentence, term and
          provision of this Section 15 is separate and distinct so that if
          any paragraph, sentence, term or provision hereof shall be held to
          be invalid or unenforceable for any reason, such invalidity or
          unenforceability shall not affect the validity or enforceability of
          any other paragraph, sentence, term or provision hereof. To the
          extent required, any


                                      13



          paragraph, sentence, term or provision of this Section 15 may be
          modified by a court of competent jurisdiction to preserve its
          validity and to provide the claimant with, subject to the
          limitations set forth in this Section 15 and any agreement between
          the corporation and claimant, the broadest possible indemnification
          permitted under applicable law.

          (j)   EFFECT OF REPEAL OR MODIFICATION. Any repeal or modification of
          this Section 15 shall not adversely affect any right of
          indemnification of a director or officer existing at the time of
          such repeal or modification with respect to any action or omission
          occurring prior to such repeal or modification.

prior fiscal year. The corporation shall use its best efforts to deliver the
statement or statements requested to the person making such request within
thirty days after the receipt thereof. A copy of any such statements shall be
kept on file in the principal executive office of the corporation for twelve
(12) months, and they shall be exhibited at all reasonable times to any
shareholder demanding an examination of them or a copy thereof shall be
mailed to such shareholder.

          The corporation shall, upon the written request of any shareholder,
mail to the shareholder a copy of the last annual, semi-annual or quarterly
income statement which it has prepared, together with a balance sheet as of
the and of the same period. The financial statements referred to in this
Section shall be accompanied by the report thereon, if there be any, of any
independent accountants engaged by the corporation in respect thereof or, if
there be no such report, the certificate of an authorized officer of the
corporation that such financial statements were prepared without audit from
the books and records of the corporation.

          Section 5. CERTIFICATES FOR SHARES. Every holder of shares in the
corporation shall be entitled to have a certificate signed in the name of the
corporation by the chairman or vice chairman of the Board or the president or
any vice president and by the chief financial officer or


                                      17



an assistant treasurer or the secretary or any assistant secretary, certifying
the number of shares and the class or series of shares owned by the
shareholder. Any of the signatures on the certificate may be facsimile,
provided that in such event at least one signature, including that of either
officer or the corporation's registrar or transfer agent, if any, shall be
manually signed. In case any officer, transfer agent or registrar who has
signed or whose facsimile signature has been placed upon a certificate shall
have ceased to be an officer, transfer agent or registrar before such
certificate is issued, it may nevertheless be issued by the corporation with
the same effect as if such person were an officer, transfer agent or registrar
at the date of issue. Any such certificate shall also contain such legend or
other statement as may be required by Section 418 of the General Corporation
Law, the Corporate Securities Law of 1968, the federal securities laws, these
Bylaws, and any agreement between the corporation and the issuee thereof.

          Certificates for shares may be issued prior to full payment under
such restrictions and for such purposes as the Board of Directors or these
Bylaws may provide; provided, however, that any such certificate so issued
prior to full payment shall state on the face thereof the amount remaining
unpaid and the terms of payment thereof.

          No new certificate for shares shall be issued in lieu of an old
certificate unless the latter is surrendered and cancelled at the same time;
provided, however, that a new certificate will be issued without surrender
and cancellation of the old certificate if (1) the old certificate is lost,
apparently destroyed or wrongfully taken; (2) the request for issuance of a
new certificate is made within a reasonable time after the owner of the old
certificate has notice of its loss, destruction or theft; (3) the request for
issuance of a new certificate is made prior to the receipt of notice by the
corporation that the old certificate has been acquired by a bona fide
purchaser; (4) the owner of the old certificate files a sufficient indemnity
bond with or provides other adequate security to the corporation; and (5) the
owner satisfies any other reasonable requirements imposed by the corporation.
In the event of the issuance of a new certificate, the rights and liabilities
of the corporation, and of the holders of the old and new certificates, shall
be governed by the provisions of Sections 8104 and 8405 of the California
Uniform Commercial Code.

          Section 6. REPRESENTATION OF SHARES OF OTHER CORPORATIONS. The
president or any vice president and the secretary or any assistant secretary
of this corporation are authorized to vote, represent and exercise on behalf
of this corporation all rights incident to any and all shares of any other
corporation or corporations standing in the name of this corporation. The
authority granted to said officers to vote or represent on behalf of this
corporation any and all shares held by this corporation in any other
corporation or corporations may be exercised either by such officers in
person or by any other person authorized so to do by proxy or power of
attorney duly executed by said officers.

          Section 7. INSPECTION OF BYLAWS. The corporation shall keep in its
principal executive office in California, or, if its principal executive
office is not in California, then at its principal business office in
California (or otherwise provide upon written request of any shareholder) the
original or a copy of these Bylaws as amended or otherwise altered to date,
certified by the secretary of the corporation, which shall be open to
inspection by the shareholders at all reasonable times during office hours.

          Section 8. CONSTRUCTION AND DEFINITIONS. Unless the context

foregoing, the masculine gender includes the feminine and neuter, the
singular includes the plural and the plural number includes the singular, and
the term "person" includes a corporation or other entity as well as a natural
