      SECTION 3.3. Election Qualification and Term of Office of Directors.
Directors shall be elected at each annual meeting of stockholders to hold office

holders of any class or series of stock having a preference over the common
stock as to dividends or upon liquidation, nominations for the election of
directors may be made by the board of directors or by any stockholder entitled

election of directors at a meeting may nominate persons for election as
directors only if written notice of such stockholder's intent to make such
nomination is given, either by personal delivery or by United States mail,
postage prepaid, to the secretary of the corporation not later than (i) with
respect to an election to be held at an annual meeting of stockholders, ninety
days in advance of such meeting, and (ii) with respect to an election to be held
at a special meeting of stockholders for the election of directors, the close of
business on the seventh day following the

                                     - 5 -

date on which notice of such meeting is first given to stockholders. Each such
notice shall set forth: (a) the name and address of the stockholder who intends
to make the nomination and of the person or persons intended to be nominated;
(b) a representation that the stockholder is a holder of record of stock of the
corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting to nominate the person or persons specified in the
notice; (c) a description of all arrangements or understandings between the
stockholder and each nominee and any other person or persons (naming such person
or persons) pursuant to which the nomination or nominations are to be made by
the stockholder; (d) such other information regarding each nominee proposed by
such stockholder as would have been required to be included in a proxy statement
filed pursuant to the proxy rules of the Securities and Exchange Commission had
each nominee been nominated, or intended to be nominated, by the board of
directors; and (e) the consent of each nominee to serve as a director of the
corporation if so elected. The chairman of the meeting may refuse to acknowledge
the nomination of any person not made in compliance with the foregoing
procedure.

      SECTION 3.5. First Meetings. The first meeting of each newly elected board
of directors shall be held immediately after and at the same location as (unless
otherwise notified) the annual meeting of stockholders and no notice of such
meeting shall be necessary to the newly elected directors in order legally to

failure of the stockholders to fix the time or place of such first meeting of
the newly elected board of directors, or in the event such meeting is not held
at the time and place so fixed by the stockholders, the meeting may be held at
such time and place as shall be specified in a notice given as hereinafter
provided for special meetings of the board of directors, or as shall be
specified in a written waiver signed by all of the directors.

determined by the board at the annual meeting of the board.

      SECTION 3.7. Special Meetings. Special meetings of the board may be called
by the chairman of the board or the president, and shall be called by the
president or secretary on the written request of two directors unless the board
consists of only one director, in which case special meetings shall be called by
the president or secretary in like manner and on like notice on the written
request of the sole director.

      SECTION 3.8. Quorum, Vote Necessary for Action. Except as may be otherwise
specifically provided by statute, by the certificate of incorporation or these
bylaws, at all meetings of the board, a majority of the entire board of
directors shall constitute a quorum for the transaction of business and the act
of a majority of the directors present at any meeting at which there is a quorum
shall be the act of the board of directors. If a quorum shall not be present at
any meeting of the board of directors, the directors present thereat may adjourn
the meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

      SECTION 3.9. 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 members of the board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of the proceedings of the board or committee.

      SECTION 3.10. Telephone and Similar Meetings. Unless otherwise restricted

participate in a meeting of the board of directors, or any committee, by means
of conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other, and such
participation in a meeting shall constitute presence in person at the meeting.

      SECTION 3.11. Notice of Meetings. Notice of regular meetings of the board
of directors or of any adjourned meeting thereof need not be given. Notice of
each special meeting of the board shall be mailed to each director, addressed to
such director at such director's residence or usual place of business (or such
other place as such director may direct in writing to the Secretary of the
Company), at least two days before the day on which the meeting is to be held or
shall be sent to such director at such place by telegraph or telecopy or be
given personally or by telephone, not later than the day before the meeting is
to be held, but notice need not be given to any director who shall, either
before or after the meeting, submit a signed waiver of such notice or who shall
attend such meeting without protesting, prior to or at its commencement, the
lack of notice to such director. Every such notice shall state the time and
place but need not state the purpose of the meeting.

      SECTION 3.12. Chairman of the Board. The board of directors may choose a
chairman of the board among its members. The chairman of the board shall, if
there be such a position, preside at meetings of the board of directors and, if
present, and in the absence of the president, preside at meetings of the
stockholders. Except as otherwise provided by resolution of the board, the
chairman of the board shall be ex-officio a member of all committees of the
board.

of its meetings and management of the affairs of the corporation as the board
may deem proper.

      SECTION 3.14. Resignations. Any director of the corporation may at any
time resign by giving written notice to the board of directors, the chairman of
the board, the president or the secretary of the corporation. Such resignation
shall take effect at the time specified therein or, if the time be not
specified, upon receipt thereof; and, unless otherwise specified therein, the
acceptance of such resignation shall not be necessary to make it effective.

      SECTION 3.15. Removal of Directors. Unless otherwise restricted by
statute, by the certificate of incorporation or by these Bylaws, any director or
the entire board of directors may be removed, with or without cause by the
holders of a majority of the shares then entitled to vote at an election of
directors.

      SECTION 3.16. Vacancies. Subject to the rights of the holders of any class
or series of stock having a preference over the common stock of the corporation
as to dividends or upon liquidation, any vacancies on the board of directors
resulting from death, resignation, removal or other cause, shall only be filled
by the affirmative vote of a majority of the remaining directors then in office,
even though less than a quorum of the board of directors, or by a sole remaining
director, and newly created directorships resulting from any increase in the
number of directors shall be filled by the board of directors, or if not so
filled, by the stockholders at the next annual meeting thereof or at a special
meeting called for that purpose in accordance with SECTION 2.5 of ARTICLE II of
these Bylaws. Any director elected in accordance with the preceding sentence of

                          INDEMNIFICATION OF DIRECTORS,
                         OFFICERS, EMPLOYEES AND AGENTS

      SECTION 7.1. Third-Party Actions. The corporation shall indemnify 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 (other than an action by or in the
right of the corporation) by reason of the fact that such person is or was a
director or officer of the corporation, or is or was serving at the request of
the corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise, against all expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which such
person reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, that such
person had reasonable cause to believe that his or her conduct was unlawful.

      The corporation may indemnify any employee or agent of the corporation, or
any employee or agent serving at the request of the corporation as an employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, in the manner and to the extent that it shall indemnify any director
or officer under this SECTION 7.1.

a director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against all expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection with the defense or settlement of such
action or suit if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made with respect to any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of such person's duty to
the corporation unless and only to the extent that the Court of Chancery of
Delaware or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery of Delaware or such
other court shall deem proper.

      SECTION 7.3. Determination of Indemnification. Any indemnification under
SECTION 7.1 or 7.2 of this ARTICLE 7 (unless ordered by a court) shall be made

that indemnification of the director, officer, employee or agent is proper in
the circumstances because such person has met the applicable standard of conduct
set forth in SECTION 7.1 or 7.2 of this ARTICLE 7. Such determination shall be
made (i) by the board of directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (ii) if
such a quorum is not obtainable, or,

                                     - 18 -

even if obtainable, a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion, or (iii) by the stockholders.

      SECTION 7.4. Right to Indemnification. Notwithstanding the other
provisions of this ARTICLE 7, to the extent that a director, officer, employee
or agent of the Corporation has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in SECTION 7.1 or 7.2 of
this ARTICLE 7, or in defense of any claim, issue or matter therein, such person
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection therewith.

      SECTION 7.5. Advance of Expenses. Expenses incurred in defending a civil
or criminal action, suit or proceeding may be paid by the corporation on behalf
of a director, officer, employee or agent in advance of the final disposition of
such action, suit or proceeding as authorized by the board of directors in the
specific case upon receipt of an undertaking by or on behalf of the director,
officer, employee or agent to repay such amount unless it shall ultimately be
determined that such person is entitled to be indemnified by the corporation as
authorized in this ARTICLE 7.

      SECTION 7.6. Indemnification Not Exclusive. The indemnification provided
by this ARTICLE 7 shall not be deemed exclusive of any other rights to which any
person seeking indemnification may be entitled under any law, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in such
person's official capacity and as to action in another capacity while holding
such office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

as a director, officer, employee or agent of another corporation, partnership,

such person and incurred by such person in any such capacity, or arising out of
such person's status as such, whether or not the corporation would have the
power to indemnify such person against liability under the provisions of this
ARTICLE 7.

      SECTION 7.8. Definitions of Certain Terms. For purposes of this ARTICLE 7,
references to "the corporation" shall include, in addition to the resulting
corporation, any constituent corporation (including 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, 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 Article 7 with respect to the resulting or surviving corporation as such
person would have with respect to such constituent corporation if its separate
existence had continued.

      For purposes of this ARTICLE 7, 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; 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,

which such director shall be liable under Section 174 of Title 8 of the Delaware
Code (relating to the Delaware General Corporation Law) or any amendment thereto
or successor provision thereto or shall be liable by reason that, in addition to
any and all other requirements for such liability, he (i) shall have breached
his duty of loyalty to the Corporation or its stockholders, (ii) shall not have
acted in good faith, (iii) shall have acted in a manner involving intentional
misconduct or a knowing violation of law or, in failing to act, shall have acted
in a manner involving intentional misconduct or a knowing violation of law or
(iv) shall have derived an improper personal benefit.

claiming the certificate of stock to be lost, stolen or destroyed. When
authorizing such issue of a new certificate or certificates, the board of
directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require and/or to give the corporation a bond in such sum as it may
direct as indemnity against any claim that may be made against the corporation

transaction upon its books.

therefor, whether or not such participation or vote was necessary for the
authorization of such contract or transaction.

in good faith authorizes or ratifies the contract or transaction by a majority

determining whether a quorum is present but not in calculating the majority
necessary to carry the vote; or
