of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and 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 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, or if not

be produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

      SECTION 2.04. Special Meeting. Special meetings of the stockholders, for
any purpose or purposes, unless otherwise prescribed by statute or by the
Certificate of Incorporation, may be called by the Chairman of the Board or by
the President or by the Board of Directors or by written order of a majority of

special meeting of stockholders, stating the time, place and purpose or purposes
thereof, shall be given to each stockholder entitled to vote thereat, not less

      SECTION 2.06. Quorum. The holders of a majority of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at any meeting of stockholders for the
transaction of business except as otherwise provided by statute or by the

represented by proxy, whether or not a quorum is present, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented. If the adjournment

for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the meeting. At such adjourned
meeting at which a quorum shall be present or represented any business may be
transacted which might have been transacted at the meeting as originally

      SECTION 2.07. Voting. When a quorum is present at any meeting of the
stockholders, the vote of the holders of a majority of the stock having voting

by-laws, a different vote is required, in which case such express provision
shall govern and control the decision of such question. Every stockholder having
the right to vote shall be entitled to vote in person, or by proxy appointed by
an instrument in writing subscribed by such stockholder, bearing a date not more
than three years prior to voting, unless such instrument provides for a longer
period, and filed with the Secretary of the corporation before, or at the time

as proxies, unless such instrument shall provide the contrary, a majority of
such persons present at any meeting at which their powers thereunder are to be
exercised shall have and may exercise all the powers of voting or giving
consents thereby conferred, or if only one be present, then such powers may be
exercised by that one; or, if an even number attend and a majority do not agree
on any particular issue, each proxy so attending shall be entitled to exercise
such powers in respect of the same portion of the shares as he is of the proxies
representing such shares.

      SECTION 2.08. Consent of Stockholders. Whenever the vote of stockholders
at a meeting thereof is required or permitted to be taken for or in connection
with any corporate action by any provision of the statutes, the meeting and vote
of stockholders may be dispensed with if all the stockholders who would have
been entitled to vote upon the action if such meeting were held shall consent in
writing to such corporate action being taken; or on the written consent of the
holders of stock having not less than the minimum percentage of the vote
required by statute for the proposed corporate action, and provided that prompt
notice must be given to all stockholders of the taking of corporate action
without a meeting and by less than unanimous written consent.

      SECTION 2.09. Voting of Stock of Certain Holders. Shares standing in the
name of another

                                     - 2 -

provision, as the Board of Directors of such corporation may determine. Shares
standing in the name of a deceased person may be voted by the executor or
administrator of such deceased person, either in person or by proxy. Shares
standing in the name of a guardian, conservator or trustee may be voted by such
fiduciary, either in person or by proxy, but no such fiduciary shall be entitled
to vote shares held in such fiduciary capacity without a transfer of such shares
into the name of such fiduciary. Shares standing in the name of a receiver may
be voted by such receiver. A stockholder whose shares are pledged shall be
entitled to vote such shares, unless in the transfer by the pledger on the books
of the corporation, he has expressly empowered the pledgee to vote thereon, in
which case only the pledgee, or his proxy, may represent the stock and vote
thereon.

      SECTION 2.10. Treasury Stock. The corporation shall not vote, directly or
indirectly, shares of its own stock owned by it; and such shares shall not be
counted in determining the total number of outstanding shares.

the allotment of rights, or the date when any change, or conversion or exchange
of capital stock shall go into effect, or a date in connection with obtaining a
consent, as a record date for the determination of the stockholders entitled to
notice of, and to vote at, any such meeting and any adjournment thereof, or
entitled to receive payment of any such dividend or distribution, or to receive
any such allotment of rights, or to exercise the rights in respect of any such
change, conversion or exchange of capital stock, or to give such consent, and in
such case such stockholders and only such stockholders as shall be stockholders
of record on the date so fixed shall be entitled to such notice of, and to vote
at, any such meeting and any adjournment thereof, or to receive payment of such
dividend or distribution, or to receive such allotment of rights, or to exercise
such rights, or to give such consent, as the case may be, notwithstanding any
transfer of any stock on the books of the corporation after any such record date
fixed as aforesaid.

of any director elected by all of the stockholders having the right to vote as a
single class or (ii) any new directorship is created by an increase in the

meetings of the Board of Directors shall be given to each director at least 48
hours prior to the time of such meeting. Any director may waive notice of any
meeting. The attendance of a director at any meeting shall constitute a waiver
of notice of such meeting, except where a director attends a meeting for the
purpose of objecting to the transaction of any business because the meeting is
not lawfully called or convened. Neither the business to be transacted at, nor
the purpose of, any special meeting of the Board of Directors need be specified

of such committee, as the case may be, and such written consent is filed with
the minutes of proceedings of the Board or committee.

      SECTION 3.09. Compensation. Directors, as such, shall not be entitled to

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. Such committee
or committees shall have such name or names and such limitations of authority as
may be determined from time to time by resolution adopted by the Board of

qualifications, limitations or restrictions of such preferences and rights shall
be set forth in full or summarized on the face or back of the certificate which
the corporation shall issue to represent such class of stock; provided that,
except as otherwise provided by statute, in lieu of the foregoing requirements
there may be set forth on the face or back of the certificate which the
corporation shall issue to represent such class or series of stock, a statement
that the corporation will furnish to each stockholder who so requests the
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 rights. All certificates
surrendered to the corporation for transfer shall be canceled and no new
certificate shall be issued until the former certificate for a like number of
shares shall have been surrendered and cancelled, except that in the case of a
lost, stolen, destroyed or mutilated certificate a new one may be issued
therefor upon such terms and with such indemnity, if any, to the corporation as
the Board of Directors may prescribe. Certificates shall not be issued
representing fractional shares of stock.

      SECTION 8.02. Lost Certificates. The Board of Directors may direct a new
certificate or certificates to 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 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 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
with respect to the certificate or certificates alleged to have been lost,
stolen or destroyed, or both.

      SECTION 8.03. Transfers. Upon surrender to the corporation or the transfer
agent of the corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books. Transfers of shares shall be made only on the books
of the corporation by the registered holder thereof, or by his attorney
thereunto authorized by power of attorney and filed with the Secretary of the
corporation or the Transfer Agent.

      SECTION 8.04. Registered Stockholders. The corporation shall be entitled
to treat the holder of record of any share or shares of stock as the holder in
fact thereof and, accordingly, shall not be bound to recognize any equitable or
other 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 the State of Delaware.

                                   ARTICLE IX

                                    DIVIDENDS

      SECTION 9.01. Declaration. Dividends upon the capital stock of the
corporation, subject to the provisions of the Certificate of Incorporation, if
any, may be declared by the Board of Directors at any regular or special
meeting, pursuant to law. Dividends may be paid in cash, in property or in
shares of capital stock, subject to the provisions of the Certificate of
Incorporation.

      SECTION 9.02. 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
interest of the corporation, and the Directors may modify or abolish any such
reserve in the manner in which it was created.

                                 INDEMNIFICATION

      SECTION 10.01. 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 he is or was 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
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
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 conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement or 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 he
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
reasonable cause to believe that his conduct was unlawful.

      SECTION 10.02. Actions by or in the Right of the Corporation. 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 or suit by or in
the right of the corporation to procure a judgment in its favor by reason of the
fact that he is or was 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 expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery 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 or such other court
shall deem proper.

      SECTION 10.03. Mandatory Indemnification. 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
Sections 10.01 and 10.02, or in defense of any claim, issue or matter therein,
he shall be indemnified against expenses (including attorneys' fees) actually
and reasonably incurred by him in connection therewith.

      SECTION 10.04. Determination of Conduct. The determination that a
director, officer, employee or agent has met the applicable standard of conduct
set forth in Sections 10.01 and 10.02 (unless indemnification is ordered by a
court) shall be made (a) 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 (b) 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, or (c) by the stockholders.

      SECTION 10.05. Payment of Expenses in Advance. Expenses incurred in
defending a civil or criminal action, suit or proceeding shall be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the director,
officer, employee or agent to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation as
authorized in this Article X.

      SECTION 10.06. Indemnity Not Exclusive. The indemnification and
advancement of expenses provided by, or granted pursuant to, the other sections
of this Article X shall not be deemed exclusive of any other rights to which
those seeking indemnification or advancement of expenses may be entitled under
the Certificate of Incorporation, any other by-law, 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 such
office.

      its directors, officers, and employees or agents, so that any person who
      is or was a director, officer,

      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

            (e) "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
      opposed to the best interests of the corporation" as referred to in this

person.
