                           CALIPER TECHNOLOGIES CORP.

                            (A DELAWARE CORPORATION)

                                    ARTICLE I

                                   ARTICLE III

                             STOCKHOLDERS' MEETINGS

         SECTION 4.        PLACE OF MEETINGS. Meetings of the stockholders of
the corporation shall be held at such place, either within or without the State
of Delaware, as may be designated from time to time by the Board of Directors,
or, if not so designated, then at the office of the corporation required to be

         SECTION 5.        ANNUAL MEETINGS.

                  (a)      The annual meeting of the stockholders of the
corporation, for the purpose of election of directors and for such other
business as may lawfully come before it, shall be held on such date and at such
time as may be designated from time to time by the Board of Directors.
Nominations of persons for election to the Board of Directors of the corporation
and the proposal of business to be considered by the stockholders may be made at
an annual meeting of stockholders: (i) pursuant to the corporation's notice of
meeting of stockholders; (ii) by or at the direction of the Board of Directors;
or (iii) by any stockholder of the corporation who was a

                                       1.

<PAGE>

stockholder of record at the time of giving of notice provided for in the
following paragraph, who is entitled to vote at the meeting and who complied
with the notice procedures set forth in Section 5.

                  (b)      At an annual meeting of the stockholders, only such
business shall be conducted as shall have been properly brought before the
meeting. For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (c) of Section 5(a) of these
Bylaws, (i) the stockholder must have given timely notice thereof in writing to
the Secretary of the corporation, (ii) such other business must be a proper
matter for stockholder action under the Delaware General Corporation Law
("DGCL"), (iii) if the stockholder, or the beneficial owner on whose behalf any
such proposal or nomination is made, has provided the corporation with a
Solicitation Notice (as defined in this Section 5(b)), such stockholder or
beneficial owner must, in the case of a proposal, have delivered a proxy
statement and form of proxy to holders of at least the percentage of the
corporation's voting shares required under applicable law to carry any such
proposal, or, in the case of a nomination or nominations, have delivered a proxy
statement and form of proxy to holders of a percentage of the corporation's
voting shares reasonably believed by such stockholder or beneficial owner to be
sufficient to elect the nominee or nominees proposed to be nominated by such
stockholder, and must, in either case, have included in such materials the
Solicitation Notice, and (iv) if no Solicitation Notice relating thereto has
been timely provided pursuant to this section, the stockholder or beneficial
owner proposing such business or nomination must not have solicited a number of
proxies sufficient to have required the delivery of such a Solicitation Notice
under this Section 5. To be timely, a stockholder'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 ninetieth (90th) day nor earlier than the
close of business on the one hundred twentieth (120th) day prior to the first
anniversary of the preceding year's annual meeting; provided, however, that in
the event that the date of the annual meeting is advanced more than thirty (30)
days prior to or delayed by more than thirty (30) days after the anniversary of
the preceding year's annual meeting, notice by the stockholder to be timely must
be so delivered not earlier than the close of business on the one hundred
twentieth (120th) day prior to such annual meeting and not later than the close
of business on the later of the ninetieth (90th) day prior to such annual
meeting or the tenth (10th) day following the day on which public announcement
of the date of such meeting is first made. In no event shall the public
announcement of an adjournment of an annual meeting commence a new time period
for the giving of a stockholder's notice as described above. Such stockholder's
notice shall set forth: (A) as to each person whom the stockholder proposed 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 Securities Exchange Act of 1934, as
amended (the "1934 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); (B) as to any other business that the
stockholder 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
stockholder and the beneficial owner, if any, on whose behalf the proposal is
made; and (C) as to the stockholder giving the notice and the beneficial owner,
if any, on whose behalf the nomination or proposal is made (i) the name and
address of such stockholder, as they appear on the corporation's books,

                                       2.

<PAGE>

and of such beneficial owner, (ii) the class and number of shares of the
corporation which are owned beneficially and of record by such stockholder and
such beneficial owner, and (iii) whether either such stockholder or beneficial
owner intends to deliver a proxy statement and form of proxy to holders of, in
the case of the proposal, at least the percentage of the corporation's voting
shares required under applicable law to carry the proposal or, in the case of a
nomination or nominations, a sufficient number of holders of the corporation's
voting shares to elect such nominee or nominees (an affirmative statement of
such intent, a "Solicitation Notice").

                  (c)      Notwithstanding anything in the second sentence of
Section 5(b) of these Bylaws to the contrary, in the event that the number of
directors to be elected to the Board of Directors of the Corporation is
increased and there is no public announcement naming all of the nominees for
director or specifying the size of the increased Board of Directors made by the
corporation at least one hundred (100) days prior to the first anniversary of
the preceding year's annual meeting, a stockholder's notice required by this
Section 5 shall also be considered timely, but only with respect to nominees for
any new positions created by such increase, if it shall be delivered to the
Secretary at the principal executive offices of the corporation not later than
the close of business on the tenth (10th) day following the day on which such
public announcement is first made by the corporation.

                  (d)      Only such persons who are nominated in accordance
with the procedures set forth in this Section 5 shall be eligible to serve as
directors and only such business shall be conducted at a meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 5. Except as otherwise provided by law, the Chairman
of the meeting shall have the power and duty to determine whether a nomination
or any business proposed to be brought before the meeting was made, or proposed,
as the case may be, in accordance with the procedures set forth in these Bylaws
and, if any proposed nomination or business is not in compliance with these
Bylaws, to declare that such defective proposal or nomination shall not be
presented for stockholder action at the meeting and shall be disregarded.

                  (e)      Notwithstanding the foregoing provisions of this
Section 5, in order to include information with respect to a stockholder
proposal in the proxy statement and form of proxy for a stockholder's meeting,
stockholders must provide notice as required by the regulations promulgated
under the 1934 Act. Nothing in these Bylaws shall be deemed to affect any rights
of stockholders to request inclusion of proposals in the corporation proxy
statement pursuant to Rule 14a-8 under the 1934 Act.

                  (f)      For purposes of this Section 5, "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 1934 Act.

         SECTION 6.        SPECIAL MEETINGS.

                  (a)      Special meetings of the stockholders of the
corporation may be called, for any purpose or purposes, by (i) the Chairman of
the Board of Directors, (ii) the Chief Executive

                                       3.

<PAGE>

Officer, (iii) the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized directors (whether or not there exist
any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board of Directors for adoption), or (iv) by the
holders of shares entitled to cast not less than ten percent (10%) of the votes
at the meeting; provided, however, that following registration of any of the
classes of equity securities of the corporation pursuant to the provisions of
the Securities Exchange Act of 1934, as amended, special meetings of the
stockholders may only be called as set forth in (i), (ii) or (iii) above, except
as otherwise required below.

         At any time or times that the corporation is subject to Section 2115(b)
of the California General Corporation Law ("CGCL"), stockholders holding five
percent (5%) or more of the outstanding shares shall have the right to call a
special meeting of stockholders only as set forth in Section 18(c) herein.

                  (b)      If a special meeting is properly called by any person
or persons other than the Board of Directors, the request shall be in writing,
specifying the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or by telegraphic or
other facsimile transmission to the Chairman of the Board of Directors, the
Chief Executive Officer, or the Secretary of the corporation. No business may be
transacted at such special meeting otherwise than specified in such notice. The
Board of Directors shall determine the time and place of such special meeting,
which shall be held not less than thirty-five (35) nor more than one hundred
twenty (120) days after the date of the receipt of the request. Upon
determination of the time and place of the meeting, the officer receiving the
request shall cause notice to be given to the stockholders entitled to vote, in
accordance with the provisions of Section 7 of these Bylaws. If the notice is
not given within one hundred (100) days after the receipt of the request, the
person or persons properly requesting the meeting may set the time and place of
the meeting and give the notice. Nothing contained in this paragraph (b) shall
be construed as limiting, fixing, or affecting the time when a meeting of
stockholders called by action of the Board of Directors may be held.

                  (c)      Nominations of persons for election to the Board of
Directors may be made at a special meeting of stockholders at which directors
are to be elected pursuant to the corporation's notice of meeting (i) by or at
the direction of the Board of Directors or (ii) by any stockholder of the
corporation who is a stockholder of record at the time of giving notice provided
for in these Bylaws who shall be entitled to vote at the meeting and who
complies with the notice procedures set forth in this Section 6(c). In the event
the corporation calls a special meeting of stockholders for the purpose of
electing one or more directors to the Board of Directors, any such stockholder
may nominate a person or persons (as the case may be), for election to such
position(s) as specified in the corporation's notice of meeting, if the
stockholder's notice required by Section 5(b) of these Bylaws shall be delivered
to the Secretary at the principal executive offices of the corporation not
earlier than the close of business on the one hundred twentieth (120th) day
prior to such special meeting and not later than the close of business on the
later of the ninetieth (90th) day prior to such meeting or the tenth (10th) day
following the day on which public announcement is first made of the date of the
special meeting and of the nominees proposed by the Board of Directors to be
elected at such meeting. In no

                                       4.

<PAGE>

event shall the public announcement of an adjournment of a special meeting
commence a new time period for the giving of a stockholder's notice as described
above.

         SECTION 7.        NOTICE OF MEETINGS. Except as otherwise provided by
law or the Certificate of Incorporation, written notice of each meeting of
stockholders shall be given not less than ten (10) nor more than sixty (60) days
before the date of the meeting to each stockholder entitled to vote at such
meeting, such notice to specify the place, date and hour and purpose or purposes
of the meeting. Notice of the time, place and purpose of any meeting of
stockholders may be waived in writing, signed by the person entitled to notice
thereof, either before or after such meeting, and will be waived by any
stockholder by his attendance thereat in person or by proxy, except when the
stockholder attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened. Any stockholder so waiving notice of such
meeting shall be bound by the proceedings of any such meeting in all respects as
if due notice thereof had been given.

         SECTION 8.        QUORUM. At all meetings of stockholders, except where
otherwise provided by statute or by the Certificate of Incorporation, or by
these Bylaws, the presence, in person or by proxy duly authorized, of the
holders of a majority of the outstanding shares of stock entitled to vote shall
constitute a quorum for the transaction of business. In the absence of a quorum,
any meeting of stockholders may be adjourned, from time to time, either by the
chairman of the meeting or by vote of the holders of a majority of the shares
represented thereat, but no other business shall be transacted at such meeting.
The stockholders present at a duly called or convened meeting, at which a quorum
is present, may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum. Except as
otherwise provided by statute, the Certificate of Incorporation or these Bylaws,
in all matters other than the election of directors, the affirmative vote of the
majority of shares present in person or represented by proxy at the meeting and
entitled to vote on the subject matter shall be the act of the stockholders.
Except as otherwise provided by statute, the Certificate of Incorporation or
these Bylaws, directors shall be elected by a plurality of the votes of the
shares present in person or represented by proxy at the meeting and entitled to
vote on the election of directors. Where a separate vote by a class or classes
or series is required, except where otherwise provided by the statute or by the
Certificate of Incorporation or these Bylaws, a majority of the outstanding
shares of such class or classes or series, present in person or represented by
proxy, shall constitute a quorum entitled to take action with respect to that
vote on that matter and, except where otherwise provided by the statute or by
the Certificate of Incorporation or these Bylaws, the affirmative vote of the
majority (plurality, in the case of the election of directors) of the votes cast
by the holders of shares of such class or classes or series shall be the act of
such class or classes or series.

         SECTION 9.        ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS. Any
meeting of stockholders, whether annual or special, may be adjourned from time
to time either by the chairman of the meeting or by the vote of a majority of
the shares casting votes. When a meeting is adjourned to another time or place,
notice need not be given of the adjourned meeting if the time and place thereof
are announced at the meeting at which the adjournment is taken. At the adjourned
meeting, the corporation may transact any business which might have been

                                       5.

<PAGE>

transacted at the original meeting. If the adjournment is for more than thirty
(30) days or if after the adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.

         SECTION 10.       VOTING RIGHTS. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 12 of
these Bylaws, shall be entitled to vote at any meeting of stockholders. Every
person entitled to vote shall have the right to do so either in person or by an
agent or agents authorized by a proxy granted in accordance with Delaware law.
An agent so appointed need not be a stockholder. No proxy shall be voted after
three (3) years from its date of creation unless the proxy provides for a longer
period.

         SECTION 11.       JOINT OWNERS OF STOCK. If shares or other securities
having voting power stand of record in the names of two (2) or more persons,
whether fiduciaries, members of a partnership, joint tenants, tenants in common,
tenants by the entirety, or otherwise, or if two (2) or more persons have the
same fiduciary relationship respecting the same shares, unless the Secretary is
given written notice to the contrary and is furnished with a copy of the
instrument or order appointing them or creating the relationship wherein it is
so provided, their acts with respect to voting shall have the following effect:
(a) if only one (1) votes, his act binds all; (b) if more than one (1) votes,
the act of the majority so voting binds all; (c) if more than one (1) votes, but
the vote is evenly split on any particular matter, each faction may vote the
securities in question proportionally, or may apply to the Delaware Court of
Chancery for relief as provided in the DGCL, Section 217(b). If the instrument
filed with the Secretary shows that any such tenancy is held in unequal
interests, a majority or even-split for the purpose of subsection (c) shall be a
majority or even-split in interest.

         SECTION 12.       LIST OF STOCKHOLDERS. The Secretary shall prepare and
make, at least ten (10) days before every meeting of stockholders, a complete
list of the stockholders entitled to vote at said meeting, arranged in
alphabetical order, showing the address of each stockholder and the number of
shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not
specified, at the place where the meeting is to be held. The list shall be
produced and kept at the time and place of meeting during the whole time thereof
and may be inspected by any stockholder who is present.

         SECTION 13.       ACTION WITHOUT MEETING.

                  (a)      Unless otherwise provided in the Certificate of
Incorporation, any action required by statute to be taken at any annual or
special meeting of the stockholders, or any action which may be taken at any
annual or special meeting of the stockholders, may be taken without a meeting,
without prior notice and without a vote, if a consent in writing, setting forth
the action so taken, shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted.

                                       6.

<PAGE>

                  (b)      Every written consent shall bear the date of
signature of each stockholder who signs the consent, and no written consent
shall be effective to take the corporate action referred to therein unless,
within sixty (60) days of the earliest dated consent delivered to the
corporation in the manner herein required, written consents signed by a
sufficient number of stockholders to take action are delivered to the
corporation by delivery to its registered office in the State of Delaware, its
principal place of business or an officer or agent of the corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to a corporation's registered office shall be by hand or
by certified or registered mail, return receipt requested.

                  (c)      Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing. If the action which is consented
to is such as would have required the filing of a certificate under any section
of the DGCL if such action had been voted on by stockholders at a meeting
thereof, then the certificate filed under such section shall state, in lieu of
any statement required by such section concerning any vote of stockholders, that
written consent has been given in accordance with Section 228 of the DGCL.

                  (d)      Notwithstanding the foregoing, no such action by
written consent may be taken following the closing of the initial public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended (the "1933 Act"), covering the offer and sale of Common
Stock of the corporation (the "Initial Public Offering").

         SECTION 14.       ORGANIZATION.

                  (a)      At every meeting of stockholders, the Chairman of the
Board of Directors, or, if a Chairman has not been appointed or is absent, the
President, or, if the President is absent, a chairman of the meeting chosen by a
majority in interest of the stockholders entitled to vote, present in person or
by proxy, shall act as chairman. The Secretary, or, in his absence, an Assistant
Secretary directed to do so by the President, shall act as secretary of the
meeting.

                  (b)      The Board of Directors of the corporation shall be
entitled to make such rules or regulations for the conduct of meetings of
stockholders as it shall deem necessary, appropriate or convenient. Subject to
such rules and regulations of the Board of Directors, if any, the chairman of
the meeting shall have the right and authority to prescribe such rules,
regulations and procedures and to do all such acts as, in the judgment of such
chairman, are necessary, appropriate or convenient for the proper conduct of the
meeting, including, without limitation, establishing an agenda or order of
business for the meeting, rules and procedures for maintaining order at the
meeting and the safety of those present, limitations on participation in such
meeting to stockholders of record of the corporation and their duly authorized
and constituted proxies and such other persons as the chairman shall permit,
restrictions on entry to the meeting after the time fixed for the commencement
thereof, limitations on the time allotted to questions or comments by
participants and regulation of the opening and closing of the polls for
balloting on matters which are to be voted on by ballot. Unless and to the
extent determined by the Board of Directors or the chairman of the meeting,
meetings of stockholders shall not be required to be held in accordance with
rules of parliamentary procedure.

                                       7.

                                   ARTICLE IV

                                    DIRECTORS

         SECTION 15.       NUMBER AND TERM OF OFFICE. The authorized number of
directors of the corporation shall be fixed in accordance with the Certificate
of Incorporation. Directors need not be stockholders unless so required by the
Certificate of Incorporation. If for any cause, the directors shall not have
been elected at an annual meeting, they may be elected as soon thereafter as
convenient at a special meeting of the stockholders called for that purpose in
the manner provided in these Bylaws.

         SECTION 16.       POWERS. The powers of the corporation shall be
exercised, its business conducted and its property controlled by the Board of
Directors, except as may be otherwise provided by statute or by the Certificate
of Incorporation.

         SECTION 17.       CLASSES OF DIRECTORS.

                  (a)      Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances,
following the closing of the Initial Public Offering, the directors shall be
divided into three classes designated as Class I, Class II and Class III,
respectively. Directors shall be assigned to each class in accordance with a
resolution or resolutions adopted by the Board of Directors. At the first annual
meeting of stockholders following the closing of the Initial Public Offering,
the term of office of the Class I directors shall expire and Class I directors
shall be elected for a full term of three years. At the second annual meeting of
stockholders following the Initial Public Offering, the term of office of the
Class II directors shall expire and Class II directors shall be elected for a
full term of three years. At the third annual meeting of stockholders following
the Initial Public Offering, the term of office of the Class III directors shall
expire and Class III directors shall be elected for a full term of three years.
At each succeeding annual meeting of stockholders, directors shall be elected
for a full term of three years to succeed the directors of the class whose terms
expire at such annual meeting. During such time or times that the corporation is
subject to Section 2115(b) of the CGCL, this Section 17(a) shall become
effective and apply only when the corporation is a "listed" corporation within
the meaning of Section 301.5 of the CGCL.

                  (b)      In the event that the corporation (i) is subject to
Section 2115(b) of the CGCL and (ii) is not a "listed" corporation or ceases to
be a "listed" corporation under Section 301.5 of the CGCL, Section 17(a) of
these Bylaws shall not apply and all directors shall be elected at each annual
meeting of stockholders to hold office until the next annual meeting.

                  (c)      No person entitled to vote at an election for
directors may cumulate votes to which such person is entitled, unless, at the
time of such election, the corporation (i) is subject to Section. 2115(b) of the
CGCL and (ii) is not a "listed" corporation or ceases to be a "listed"
corporation under Section 301.5 of the CGCL. During this time, every stockholder
entitled to vote at an election for directors may cumulate such stockholder's
votes and give one candidate a number of votes equal to the number of directors
to be elected multiplied by the number of votes to which such stockholder's
shares are otherwise entitled, or distribute the stockholder's votes on the same
principle among as many candidates as such stockholder thinks fit. No
stockholder,

                                       8.

<PAGE>

however, shall be entitled to so cumulate such stockholder's votes unless (i)
the names of such candidate or candidates have been placed in nomination prior
to the voting and (ii) the stockholder has given notice at the meeting, prior to
the voting, of such stockholder's intention to cumulate such stockholder's
votes. If any stockholder has given proper notice to cumulate votes, all
stockholders may cumulate their votes for any candidates who have been properly
placed in nomination. Under cumulative voting, the candidates receiving the
highest number of votes, up to the number of directors to be elected, are
elected.

         Notwithstanding the foregoing provisions of this section, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

         SECTION 18.       VACANCIES.

                  (a)      Unless otherwise provided in the Certificate of
Incorporation, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by stockholders, be filled only
by the affirmative vote of a majority of the directors then in office, even
though less than a quorum of the Board of Directors. Any director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the director for which the vacancy was created or occurred and
until such director's successor shall have been elected and qualified. A vacancy
in the Board of Directors shall be deemed to exist under this Section 18 in the
case of the death, removal or resignation of any director.

                  (b)      If at the time of filling any vacancy or any newly
created directorship, the directors then in office shall constitute less than a
majority of the whole board (as constituted immediately prior to any such
increase), the Delaware Court of Chancery may, upon application of any
stockholder or stockholders holding at least ten percent (10%) of the total
number of the shares at the time outstanding having the right to vote for such
directors, summarily order an election to be held to fill any such vacancies or
newly created directorships, or to replace the directors chosen by the directors
then in offices as aforesaid, which election shall be governed by Section 211 of
the DGCL.

                  (c)      At any time or times that the corporation is subject
to Section 2115(b) of the CGCL, if, after the filling of any vacancy, the
directors then in office who have been elected by stockholders shall constitute
less than a majority of the directors then in office, then

                           (1)      Any holder or holders of an aggregate of
five percent (5%) or more of the total number of shares at the time outstanding
having the right to vote for those directors may call a special meeting of
stockholders; or

                           (2)      The Superior Court of the proper county
shall, upon application of such stockholder or stockholders, summarily order a
special meeting of stockholders, to be held

                                       9.

<PAGE>

to elect the entire board, all in accordance with Section 305(c) of the CGCL.
The term of office of any director shall terminate upon that election of a
successor.

         SECTION 19.       RESIGNATION. Any director may resign at any time by
delivering his written resignation to the Secretary, such resignation to specify
whether it will be effective at a particular time, upon receipt by the Secretary
or at the pleasure of the Board of Directors. If no such specification is made,
it shall be deemed effective at the pleasure of the Board of Directors. When one
or more directors shall resign from the Board of Directors, effective at a
future date, a majority of the directors then in office, including those who
have so resigned, shall have power to fill such vacancy or vacancies, the vote
thereon to take effect when such resignation or resignations shall become
effective, and each Director so chosen shall hold office for the unexpired
portion of the term of the Director whose place shall be vacated and until his
successor shall have been duly elected and qualified.

         SECTION 20.       REMOVAL.

                  (a)      During such time or times that the corporation is
subject to Section 2115(b) of the CGCL, the Board of Directors or any individual
director may be removed from office at any time without cause by the affirmative
vote of the holders of at least a majority of the outstanding shares entitled to
vote on such removal; provided, however, that unless the entire Board is
removed, no individual director may be removed when the votes cast against such
director's removal, or not consenting in writing to such removal, would be
sufficient to elect that director if voted cumulatively at an election which the
same total number of votes were cast (or, if such action is taken by written
consent, all shares entitled to vote were voted) and the entire number of
directors authorized at the time of such director's most recent election were
then being elected.

                  (b)      Following any date on which the corporation is no
longer subject to Section 2115(b) of the CGCL and subject to any limitations
imposed by law, Section 20(a) above shall no longer apply and removal shall be
as provided in Section 141(k) of the DGCL.

         SECTION 21.       MEETINGS.

                  (a)      ANNUAL MEETINGS. The annual meeting of the Board of
Directors shall be held immediately before or after the annual meeting of
stockholders and at the place where such meeting is held. No notice of an annual
meeting of the Board of Directors shall be necessary and such meeting shall be
held for the purpose of electing officers and transacting such other business as
may lawfully come before it.

                  (b)      REGULAR MEETINGS. Unless otherwise restricted by the
Certificate of Incorporation, regular meetings of the Board of Directors may be
held at any time or date and at any place within or without the State of
Delaware which has been designated by the Board of Directors and publicized
among all directors. No formal notice shall be required for regular meetings of
the Board of Directors.

                  (c)      SPECIAL MEETINGS. Unless otherwise restricted by the
Certificate of Incorporation, special meetings of the Board of Directors may be
held at any time and place

                                      10.

<PAGE>

within or without the State of Delaware whenever called by the Chairman of the
Board, the President or any two of the directors.

                  (d)      TELEPHONE MEETINGS. Any member of the Board of
Directors, or of any committee thereof, may participate in a meeting by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and participation in a
meeting by such means shall constitute presence in person at such meeting.

                  (e)      NOTICE OF MEETINGS. Notice of the time and place of
all special meetings of the Board of Directors shall be orally or in writing, by
telephone, including a voice messaging system or other system or technology
designed to record and communicate messages, facsimile, telegraph or telex, or
by electronic mail or other electronic means, during normal business hours, at
least twenty-four (24) hours before the date and time of the meeting, or sent in
writing to each director by first class mail, charges prepaid, at least three
(3) days before the date of the meeting. Notice of any meeting may be waived in
writing at any time before or after the meeting and will be waived by any
director by attendance thereat, except when the director attends the meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.

                  (f)      WAIVER OF NOTICE. The transaction of all business at
any meeting of the Board of Directors, or any committee thereof, 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 be present and if, either before
or after the meeting, each of the directors not present shall sign a written
waiver of notice. All such waivers shall be filed with the corporate records or
made a part of the minutes of the meeting.

         SECTION 22.       QUORUM AND VOTING.

                  (a)      Unless the Certificate of Incorporation requires a
greater number and except with respect to indemnification questions arising
under Section 43 hereof, for which a quorum shall be one-third of the exact
number of directors fixed from time to time in accordance with the Certificate
of Incorporation, a quorum of the Board of Directors shall consist of a majority
of the exact number of directors fixed from time to time by the Board of
Directors in accordance with the Certificate of Incorporation; provided,
however, at any meeting whether a quorum be present or otherwise, a majority of
the directors present may adjourn from time to time until the time fixed for the
next regular meeting of the Board of Directors, without notice other than by
announcement at the meeting.

                  (b)      At each meeting of the Board of Directors at which a
quorum is present, all questions and business shall be determined by the
affirmative vote of a majority of the directors present, unless a different vote
be required by law, the Certificate of Incorporation or these Bylaws.

         SECTION 23.       ACTION WITHOUT MEETING. Unless otherwise restricted
by the Certificate of Incorporation or these Bylaws, any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if all

                                      11.

<PAGE>

members of the Board of Directors or committee, as the case may be, consent
thereto in writing, and such writing or writings are filed with the minutes of
proceedings of the Board of Directors or committee.

         SECTION 24.       FEES AND COMPENSATION. Directors shall be entitled to
such compensation for their services as may be approved by the Board of
Directors, including, if so approved, by resolution of the Board of Directors, a
fixed sum and expenses of attendance, if any, for attendance at each regular or
special meeting of the Board of Directors and at any meeting of a committee of
the Board of Directors. Nothing herein contained shall be construed to preclude
any director from serving the corporation in any other capacity as an officer,
agent, employee, or otherwise and receiving compensation therefor.

         SECTION 25.       COMMITTEES.

                  (a)      EXECUTIVE COMMITTEE. The Board of Directors may
appoint an Executive Committee to consist of one (1) or more members of the
Board of Directors. The Executive Committee, to the extent permitted by law and
provided in the resolution of the Board of Directors shall have and may exercise
all the powers and authority of the Board of Directors in the management of the
business and affairs of the corporation, and may authorize the seal of the
corporation to be affixed to all papers which may require it; but no such
committee shall have the power or authority in reference to (i) approving or
adopting, or recommending to the stockholders, any action or matter expressly
required by the DGCL to be submitted to stockholders for approval, or (ii)
adopting, amending or repealing any bylaw of the corporation.

                  (b)      OTHER COMMITTEES. The Board of Directors may, from
time to time, appoint such other committees as may be permitted by law. Such
other committees appointed by the Board of Directors shall consist of one (1) or
more members of the Board of Directors and shall have such powers and perform
such duties as may be prescribed by the resolution or resolutions creating such
committees, but in no event shall any such committee have the powers denied to
the Executive Committee in these Bylaws.

                  (c)      TERM. Each member of a committee of the Board of
Directors shall serve a term on the committee coexistent with such member's term
on the Board of Directors. The Board of Directors, subject to any requirements
of any outstanding series of preferred Stock and the provisions of subsections
(a) or (b) of this Bylaw, may at any time increase or decrease the number of
members of a committee or terminate the existence of a committee. The membership
of a committee member shall terminate on the date of his death or voluntary
resignation from the committee or from the Board of Directors. The Board of
Directors may at any time for any reason remove any individual committee member
and the Board of Directors may fill any committee vacancy created by death,
resignation, removal or increase in the number of members of the committee. The
Board of Directors may designate one or more directors as alternate members of
any committee, who may replace any absent or disqualified member at any meeting
of the committee, and, in addition, in the absence or disqualification of any
member of a committee, the member or members thereof present at any meeting and
not disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.

transaction of any business because the meeting is not lawfully called or

the act of such committee.

           EXECUTION OF CORPORATE INSTRUMENTS AND VOTING OF SECURITIES
                            OWNED BY THE CORPORATION

         SECTION 32.       EXECUTION OF CORPORATE INSTRUMENTS. The Board of
Directors may, in its discretion, determine the method and designate the
signatory officer or officers, or other person or persons, to execute on behalf
of the corporation any corporate instrument or document, or to sign on behalf of

contracts on behalf of the corporation, except where otherwise provided by law
or these Bylaws, and such execution or signature shall be binding upon the

         SECTION 33.       VOTING OF SECURITIES OWNED BY THE CORPORATION. All

                                 SHARES OF STOCK

         SECTION 34.       FORM AND EXECUTION OF CERTIFICATES. Certificates for
the shares of stock of the corporation shall be in such form as is consistent
with the Certificate of Incorporation and applicable law. Every holder of stock
in the corporation shall be entitled to have a certificate signed by or in the
name of the corporation by the Chairman of the Board of Directors, or the
President or any Vice President and by the Treasurer or Assistant Treasurer or
the Secretary or Assistant Secretary, certifying the number of shares owned by
him in the corporation. Any or all of the signatures on the certificate may be
facsimiles. 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 such officer, transfer agent, or registrar before such certificate is
issued, it may be issued with the same effect as if he were such officer,
transfer agent, or registrar at the date of issue. Each certificate shall state
upon the face or back thereof, in full or in summary, all of the powers,
designations, preferences, and rights, and the limitations or restrictions of
the shares authorized to be issued or shall, except as otherwise required by
law, set forth on the face or back a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, designations,
preferences and relative, participating, optional, or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights. Within a reasonable time after
the issuance or transfer of uncertificated stock, the corporation shall send to
the registered owner thereof a written notice containing the information
required to be set forth or stated on certificates pursuant to this section or
otherwise required by law or with respect to this section a statement that the
corporation will furnish without charge to each stockholder who so requests the
powers, designations, preferences and relative participating, optional or other
special rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights. Except as
otherwise expressly provided by law, the rights and obligations of the holders
of certificates representing stock of the same class and series shall be
identical.

         SECTION 35.       LOST CERTIFICATES. A new certificate or certificates
shall be issued in place of any certificate or certificates theretofore issued
by the corporation alleged to have been lost, stolen, or destroyed, upon the
making of an affidavit of that fact by the person claiming the

                                      16.

<PAGE>

certificate of stock to be lost, stolen, or destroyed. The corporation may
require, as a condition precedent to the issuance of a new certificate or
certificates, the owner of such lost, stolen, or destroyed certificate or
certificates, or his legal representative, to agree to indemnify the corporation
in such manner as it shall require or to give the corporation a surety bond in
such form and amount as it may direct as indemnity against any claim that may be
made against the corporation with respect to the certificate alleged to have
been lost, stolen, or destroyed.

         SECTION 36.       TRANSFERS.

                  (a)      Transfers of record of shares of stock of the
corporation shall be made only upon its books by the holders thereof, in person
or by attorney duly authorized, and upon the surrender of a properly endorsed
certificate or certificates for a like number of shares.

                  (b)      The corporation shall have power to enter into and
perform any agreement with any number of stockholders of any one or more classes
of stock of the corporation to restrict the transfer of shares of stock of the
corporation of any one or more classes owned by such stockholders in any manner
not prohibited by the DGCL.

         SECTION 37.       FIXING RECORD DATES.

                  (a)      In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, the Board of Directors may fix, in advance, a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted by the Board of Directors, and which record
date shall, subject to applicable law, not be more than sixty (60) nor less than
ten (10) days before the date of such meeting. If no record date is fixed by the
Board of Directors, the record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; provided, however, that the Board of Directors may fix a new
record date for the adjourned meeting.

                  (b)      In order that the corporation may determine the
stockholders entitled to receive payment of any dividend or other distribution
or allotment of any rights or the stockholders entitled to exercise any rights
in respect of any change, conversion or exchange of stock, or for the purpose of
any other lawful action, the Board of Directors may fix, in advance, a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted, and which record date shall be not more than
sixty (60) days prior to such action. If no record date is fixed, the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating thereto.

         SECTION 38.       REGISTERED STOCKHOLDERS. The corporation shall be
entitled to recognize the exclusive right of a person registered on its books as
the owner of shares to receive dividends, and to vote as such owner, and shall
not be bound to recognize any equitable or other

                                      17.

claim to or interest in such share or shares on the part of any other person
whether or not it shall have express or other notice thereof, except as
otherwise provided by the laws of Delaware.

                       OTHER SECURITIES OF THE CORPORATION

         SECTION 39.       EXECUTION OF OTHER SECURITIES. All bonds, debentures
and other corporate securities of the corporation, other than stock certificates
(covered in Section 34), may be signed by the Chairman of the Board of
Directors, the President or any Vice President, or such other person as may be
authorized by the Board of Directors, and the corporate seal impressed thereon
or a facsimile of such seal imprinted thereon and attested by the signature of
the Secretary or an Assistant Secretary, or the Chief Financial Officer or
Treasurer or an Assistant Treasurer; provided, however, that where any such
bond, debenture or other corporate security shall be authenticated by the manual
signature, or where permissible facsimile signature, of a trustee under an
indenture pursuant to which such bond, debenture or other corporate security
shall be issued, the signatures of the persons signing and attesting the
corporate seal on such bond, debenture or other corporate security may be the
imprinted facsimile of the signatures of such persons. Interest coupons
appertaining to any such bond, debenture or other corporate security,
authenticated by a trustee as aforesaid, shall be signed by the Treasurer or an
Assistant Treasurer of the corporation or such other person as may be authorized
by the Board of Directors, or bear imprinted thereon the facsimile signature of
such person. In case any officer who shall have signed or attested any bond,
debenture or other corporate security, or whose facsimile signature shall appear
thereon or on any such interest coupon, shall have ceased to be such officer
before the bond, debenture or other corporate security so signed or attested
shall have been delivered, such bond, debenture or other corporate security
nevertheless may be adopted by the corporation and issued and delivered as
though the person who signed the same or whose facsimile signature shall have
been used thereon had not ceased to be such officer of the corporation.

                                   ARTICLE IX

                                    DIVIDENDS

         SECTION 40.       DECLARATION OF DIVIDENDS. Dividends upon the capital
stock of the corporation, subject to the provisions of the Certificate of
Incorporation and applicable law, if any, may be declared by the Board of
Directors pursuant to law at any regular or special meeting. Dividends may be
paid in cash, in property, or in shares of the capital stock, subject to the
provisions of the Certificate of Incorporation and applicable law.

         SECTION 41.       DIVIDEND RESERVE. Before payment of any dividend,
there may be set aside out of any funds of the corporation available for
dividends such sum or sums as the Board of Directors from time to time, in their
absolute discretion, think proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the corporation, or for such other purpose as the Board of Directors
shall think conducive to the interests of the corporation, and the Board of
Directors may modify or abolish any such reserve in the manner in which it was
created.

                                   ARTICLE XI

                                 INDEMNIFICATION

         SECTION 43.       INDEMNIFICATION OF DIRECTORS, EXECUTIVE OFFICERS,
OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS.

                  (a)      DIRECTORS AND EXECUTIVE OFFICERS. The corporation
shall indemnify its directors and executive officers (for the purposes of this
Article XI, "executive officers" shall have the meaning defined in Rule 3b-7
promulgated under the 1934 Act) to the fullest extent not prohibited by the DGCL
or any other applicable law; provided, however, that the corporation may modify
the extent of such indemnification by individual contracts with its directors
and executive officers; and, provided, further, that the corporation shall not
be required to indemnify any director or executive officer in connection with
any proceeding (or part thereof) initiated by such person unless (i) such
indemnification is expressly required to be made by law, (ii) the proceeding was
authorized by the Board of Directors of the corporation, (iii) such
indemnification is provided by the corporation, in its sole discretion, pursuant
to the powers vested in the corporation under the DGCL or any other applicable
law or (iv) such indemnification is required to be made under subsection (d).

                  (b)      OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS. The
corporation shall have power to indemnify its other officers, employees and
other agents as set forth in the DGCL or any other applicable law.

                  (c)      EXPENSES. The corporation shall advance to any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he is or was a
director or executive officer of the corporation, or is or was serving at the
request of the corporation as a director or executive officer of another
corporation, partnership, joint venture, trust or other enterprise, prior to the
final disposition of the proceeding, promptly following request therefor, all
expenses incurred by any director or executive officer in connection with such
proceeding upon receipt of an undertaking by or on behalf of such person to
repay said amounts if it should be determined ultimately that such person is not
entitled to be indemnified under this Section 43 or otherwise.

         Notwithstanding the foregoing, unless otherwise determined pursuant to
paragraph (e) of this Section 43, no advance shall be made by the corporation to
an executive officer of the corporation (except by reason of the fact that such
executive officer is or was a director of the corporation in which event this
paragraph shall not apply) in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, if a determination is reasonably and

                                      19.

<PAGE>

promptly made (i) by the Board of Directors by a majority vote of a quorum
consisting of directors who were not parties to the proceeding, or (ii) if such
quorum is not obtainable, or, even if obtainable, a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, that
the facts known to the decision-making party at the time such determination is
made demonstrate clearly and convincingly that such person acted in bad faith or
in a manner that such person did not believe to be in or not opposed to the best
interests of the corporation.

                  (d)      ENFORCEMENT. Without the necessity of entering into
an express contract, all rights to indemnification and advances to directors and
executive officers under this Bylaw shall be deemed to be contractual rights and
be effective to the same extent and as if provided for in a contract between the
corporation and the director or executive officer. Any right to indemnification
or advances granted by this Section 43 to a director or executive officer shall
be enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor. The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim. In connection with any claim for indemnification, the
corporation shall be entitled to raise as a defense to any such action that the
claimant has not met the standards of conduct that make it permissible under the
DGCL or any other applicable law for the corporation to indemnify the claimant
for the amount claimed. In connection with any claim by an [executive] officer
of the corporation (except in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
executive officer is or was a director of the corporation) for advances, the
corporation shall be entitled to raise a defense as to any such action clear and
convincing evidence that such person acted in bad faith or in a manner that such
person did not believe to be in or not opposed to the best interests of the
corporation, or with respect to any criminal action or proceeding that such
person acted without reasonable cause to believe that his conduct was lawful.
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 has met the applicable standard of
conduct set forth in the DGCL or any other applicable law, 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 claimant has not met the applicable standard of conduct.

                  (e)      NON-EXCLUSIVITY OF RIGHTS. The rights conferred on
any person by this Bylaw shall not be exclusive of any other right which such
person may have or hereafter acquire under any applicable statute, provision of
the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office. The corporation is
specifically authorized to enter into individual contracts with any or all of
its directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law, or by any other applicable law.

                                      20.

<PAGE>

                  (f)      SURVIVAL OF RIGHTS. The rights conferred on any
person by this Bylaw shall continue as to a person who has ceased to be a
director, officer, employee or other agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

                  (g)      INSURANCE. To the fullest extent permitted by the
DGCL or any other applicable law, the corporation, upon approval by the Board of
Directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this Section 43.

                  (h)      AMENDMENTS. Any repeal or modification of this
Section 43 shall only be prospective and shall not affect the rights under this
Bylaw in effect at the time of the alleged occurrence of any action or omission
to act that is the cause of any proceeding against any agent of the corporation.

                  (i)      SAVING CLAUSE. If this Bylaw or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the corporation shall nevertheless indemnify each director and executive officer
to the full extent not prohibited by any applicable portion of this Section 43
that shall not have been invalidated, or by any other applicable law. If this
Section 43 shall be invalid due to the application of the indemnification
provisions of another jurisdiction, then the corporation shall indemnify each
director and executive officer to the full extent under any other applicable
law.

                  (j)      CERTAIN DEFINITIONS. For the purposes of this Bylaw,
the following definitions shall apply:

                           (1)      The term "proceeding" shall be broadly

any constituent of a constituent) absorbed in a consolidation or merger which,
if its separate existence had continued, would have had power and authority to
indemnify its directors, officers, and employees or agents, so that any person
who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, shall stand in the same position under
the provisions of this Section 43 with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

                                      21.

                           (4)      References to a "director," "executive
officer," "officer," "employee," or "agent" of the corporation shall include,
without limitation, situations where such person is serving at the request of
the corporation as, respectively, a director, executive officer, officer,
employee, trustee or agent of another corporation, partnership, joint venture,
trust or other enterprise.

                           (5)      References to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not

43.

                                   ARTICLE XII

                                     NOTICES

         SECTION 44.       NOTICES.

                  (a)      NOTICE TO STOCKHOLDERS. Whenever, under any
provisions of these Bylaws, notice is required to be given to any stockholder,
it shall be given in writing, timely and duly deposited in the United States
mail, postage prepaid, and addressed to his last known post office address as
shown by the stock record of the corporation or its transfer agent.

                  (b)      NOTICE TO DIRECTORS. Any notice required to be given
to any director may be given by the method stated in subsection (a), or by
overnight delivery service, facsimile, telex or telegram, except that such
notice other than one which is delivered personally shall be sent to such
address as such director shall have filed in writing with the Secretary, or, in
the absence of such filing, to the last known post office address of such
director.

                  (c)      AFFIDAVIT OF MAILING. An affidavit of mailing,
executed by a duly authorized and competent employee of the corporation or its
transfer agent appointed with respect to the class of stock affected, specifying
the name and address or the names and addresses of the stockholder or
stockholders, or director or directors, to whom any such notice or notices was
or were given, and the time and method of giving the same, shall in the absence
of fraud, be prima facie evidence of the facts therein contained.

                  (d)      TIME NOTICES DEEMED GIVEN. All notices given by mail
or by overnight delivery service, as above provided, shall be deemed to have
been given as at the time of mailing, and all notices given by facsimile, telex
or telegram shall be deemed to have been given as of the sending time recorded
at time of transmission.

                  (e)      METHODS OF NOTICE. It shall not be necessary that the
same method of giving notice be employed in respect of all directors, but one
permissible method may be

                                      22.

employed in respect of any one or more, and any other permissible method or
methods may be employed in respect of any other or others.

                  (f)      FAILURE TO RECEIVE NOTICE. The period or limitation
of time within which any stockholder may exercise any option or right, or enjoy
any privilege or benefit, or be required to act, or within which any director
may exercise any power or right, or enjoy any privilege, pursuant to any notice
sent him in the manner above provided, shall not be affected or extended in any
manner by the failure of such stockholder or such director to receive such
notice.

                  (g)      NOTICE TO PERSON WITH WHOM COMMUNICATION IS UNLAWFUL.
Whenever notice is required to be given, under any provision of law or of the
Certificate of Incorporation or Bylaws of the corporation, to any person with
whom communication is unlawful, the giving of such notice to such person shall
not be required and there shall be no duty to apply to any governmental
authority or agency for a license or permit to give such notice to such person.
Any action or meeting which shall be taken or held without notice to any such
person with whom communication is unlawful shall have the same force and effect
as if such notice had been duly given. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the DGCL, the certificate shall state, if such is the fact and if
notice is required, that notice was given to all persons entitled to receive
notice except such persons with whom communication is unlawful.

                  (h)      NOTICE TO PERSON WITH UNDELIVERABLE ADDRESS. Whenever
notice is required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings or of the
taking of action by written consent without a meeting to such person during the
period between such two consecutive annual meetings, or (ii) all, and at least
two, payments (if sent by first class mail) of dividends or interest on
securities during a twelve-month period, have been mailed addressed to such
person at his address as shown on the records of the corporation and have been
returned undeliverable, the giving of such notice to such person shall not be
required. Any action or meeting which shall be taken or held without notice to
such person shall have the same force and effect as if such notice had been duly
given. If any such person shall deliver to the corporation a written notice
setting forth his then current address, the requirement that notice be given to
such person shall be reinstated. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the DGCL, the certificate need not state that notice was not given
to persons to whom notice was not required to be given pursuant to this
paragraph.

                                  ARTICLE XIII

                                   AMENDMENTS

         SECTION 45.       AMENDMENTS. Subject to paragraph (h) of Section 43 of
the Bylaws, the Bylaws may be altered or amended or new Bylaws adopted by the
affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of the
voting power of all of the then-outstanding shares of the voting stock of the
corporation entitled to vote. The Board of Directors shall also have the power
to adopt, amend, or repeal Bylaws.

                                      23.

                                LOANS TO OFFICERS

         SECTION 46.       LOANS TO OFFICERS. The corporation may lend money to,
or guarantee any obligation of, or otherwise assist any officer or other
employee of the corporation or of its subsidiaries, including any officer or
employee who is a Director of the corporation or its subsidiaries, whenever, in
the judgment of the Board of Directors, such loan, guarantee or assistance may
reasonably be expected to benefit the corporation. The loan, guarantee or other
assistance may be with or without interest and may be unsecured, or secured in
such manner as the Board of Directors shall approve, including, without
limitation, a pledge of shares of stock of the corporation. Nothing in these
Bylaws shall be deemed to deny, limit or restrict the powers of guaranty or
warranty of the corporation at common law or under any statute.
