the written request of two directors.

         SECTION 7. Waiver. Attendance of a director at any meeting shall
constitute a waiver of notice of such meeting, except where a director attends
for the express 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 regular or special meeting of the Board
of Directors need be specified in the notice or waiver of notice of such

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

         SECTION 10. Telephonic Communications. Unless otherwise restricted by
the Certificate of Incorporation or these by-laws, members of the Board of

equipment by means of which all persons participating in the meeting can hear

Directors when required.

         SECTION 12. Removal of Directors. Unless otherwise restricted by the

                                    ARTICLE V
                                  CAPITAL STOCK

         SECTION 1. Certificates for Shares. Every owner of stock of the
Corporation shall be entitled to have a certificate or certificates in such form
as the Board of Directors shall prescribe certifying the number of shares of
stock owned by him, except as provided below. The certificates shall be signed
by hand or by facsimile in the name of the Corporation by such officer or
officers as the Board shall appoint. The Board of Directors may provide by
resolution that the stock of the Corporation shall be uncertificated shares.
Notwithstanding the adoption of such a resolution by the Board, every holder of
uncertificated shares shall, upon request, be entitled to receive a certificate,
signed by such officers, designated by the Corporation and complying with the
statute, representing the number of shares in registered certificate form. A
record shall be kept of the names of the persons owning any such stock, whether
certificated or uncertificated, and the number of shares owned by each such
person.



         SECTION 2. Lost, Stolen or Destroyed Certificates. The Board of
Directors may direct a new certificate or certificates or uncertified shares 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 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 or uncertified shares, Board of Directors, in its discretion and as
a condition precedent to the issuance thereof, may prescribe such terms and
conditions as it deems adequate to protect the Corporation from any claim that
may be raised against it with respect to any such certificate or certificates or
uncertified shares alleged to have been lost, stolen or destroyed.

         SECTION 3. Transfer of Shares. Upon surrender to the secretary of the
Corporation, or, if a transfer agent for the Corporation has been named by the
Board of Directors, to the transfer agent, of a certificate representing shares
duly endorsed or accompanied by proper evidence of succession, assignation 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 the books of the Corporation.

         SECTION 4. Fixing Record Date. In order that the Corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
the stockholders or any adjournment thereof, or to express consent to corporate
action in writing without a meeting, or entitled to receive payment of any
dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of any
stock or for the purpose of any other lawful action, the Board of Directors may
fix, in advance, a record date, which shall not be more than sixty nor less than
ten days before the date of such meeting, nor more than sixty days prior to any
other action. 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.

         SECTION 5. 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 to hold
liable for calls and assessments a person registered on its books as the owner
of shares, and 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.

         SECTION 6. Signing Authority. Except as provided below, all contracts,
agreements, assignments, transfers, deeds, stock powers or other instruments of
the Corporation may be executed and delivered by the president or any
vice-president or by such other officer or officers, or agent or agents, of the
Corporation as shall be thereunto authorized from time to time either by the
Board of Directors or by power of attorney executed by any person pursuant to
authority granted by the Board of Directors, and the



secretary or any assistant secretary, may affix the seal of the Corporation
thereto and attest same. Certificates issued upon request to holders of
uncertificated stock shall be signed by (i) the president or any vice-president
and (ii) the secretary, or an assistant secretary.

Certificate of incorporation.

         SECTION 2. Reserves. Before payment of any dividend, there may be set

Notice to directors may also be given by telegram.

         Whenever any notice is required to be given under the provisions of
statute, the Certificate of Incorporation or of these by-laws, a waiver thereof
in writing signed by the person or persons entitled to such notice, whether

stockholders at which a quorum is present or represented, by the affirmative
vote of a majority of the shares entitled to vote, provided notice of the
proposed alteration, amendment or repeal be contained in the notice of such
