         SECTION 1.03. NOTICE OF MEETINGS OF STOCKHOLDERS. Whenever stockholders
are required or permitted to take any action at a meeting, written notice of the
meeting shall be given (unless that notice shall be waived or unless the meeting
is to be dispensed with in accordance with the provisions of the General
Corporation Law of the State of Delaware and Article SIXTH of the Certificate of
Incorporation of the Corporation) which shall state the place, date and hour of
the meeting and, in the case of a special meeting, the purpose or purposes for
which the meeting is called. The written notice of any meeting shall be given,
personally or by mail, not less than ten nor more than sixty days before the
date of the meeting to each stockholder entitled to vote at such meeting. If
mailed, such notice is given when deposited in the United States mail, postage
prepaid, directed to the stockholder at his address as it appears on the records
of the Corporation.

         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 transacted at the

                                                                              3


given to each stockholder of record entitled to vote at the meeting.

by the subsequent withdrawal of any stockholders.

         The stockholders present may adjourn the meeting despite the absence of
a quorum and at any such adjourned meeting at which the requisite amount of
voting stock shall be represented, the Corporation may transact any business
which might have been transacted at the original meeting had a quorum been there
present.

         SECTION 1.05. METHOD OF VOTING. The vote upon any question before the

         SECTION 1.06. VOTING RIGHTS OF STOCKHOLDERS AND PROXIES. Each

books of the Corporation, but no proxy shall be voted on after three years from
its date, unless the proxy provides for a longer period.

         SECTION 1.07. OWNERSHIP OF ITS OWN STOCK. Shares of its own capital
stock belonging to the Corporation or to another corporation, if a majority of
the shares entitled to vote in the election of directors of such other
corporation is held, directly or indirectly, by the Corporation, shall neither
be entitled to vote nor be counted for quorum purposes. Nothing in this section
shall be construed as limiting the right of any corporation to vote stock,
including but not limited to its own stock, held by it in a fiduciary capacity.

         SECTION 1.08. VOTING BY FIDUCIARIES AND PLEDGORS. Persons holding stock
in a fiduciary capacity shall be entitled to vote the shares so held. Persons
whose stock is pledged shall be entitled to vote, unless in the transfer by the
pledgor 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
such stock and vote thereon.

         If shares or other securities having voting power stand of record in
the names of two or more persons, whether fiduciaries, members of a partnership,
joint tenants, tenants in common, tenants by the entirety or otherwise, or if
two or more persons have the same fiduciary relationship respecting the same
shares, unless the Secretary of the Corporation 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:

         (1) If only one votes, his act binds all;

         (2) If more than one vote, the act of the majority so voting binds all;

         (3) If more than one vote, but the vote is evenly split on any
particular matter, each faction may vote the securities in question
proportionally, or any person voting the shares, or a beneficiary, if any, may
apply to the Court of Chancery or such other court as may have jurisdiction to
appoint an additional person to act with the persons so voting the shares, which
shall then be voted as determined by a majority of such persons and the person
appointed by the Court. If the instrument so filed shows that any such tenancy
is held in unequal interests, a majority or even-split for the purpose of this
subsection shall be a majority or even-split in interest.

         SECTION 1.09. FIXING DATE FOR DETERMINATION OF STOCKHOLDERS OF RECORD.
In order to determine the stockholders (i) entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, or (ii) entitled to

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. If no record date is fixed
by the Board of Directors, the record date shall be determined in accordance
with the provisions of the General Corporation Law of the State of Delaware.

         SECTION 1.10. LIST OF STOCKHOLDERS. The officer who has charge of the
stock ledger of the Corporation shall prepare and make, at least ten days before
every meeting of the 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 of
the meeting or, if not so specified, at the place where said meeting is to be
held), and the list shall be produced and kept at the time and place of the
meeting during the whole time thereof, and may be inspected by any stockholder

         SECTION 1.11. STOCKHOLDER'S RIGHT OF INSPECTION. Stockholders of
record, in person or by attorney or other agent, shall have the right, upon
written demand under oath stating the purpose thereof, during the usual hours
for business to inspect for any proper purpose the Corporation's stock ledger, a
list of its stockholders, and its other books and records, and to make copies or
extracts therefrom. A proper purpose shall mean a purpose reasonably related to
such person's interest as a stockholder. In every instance where an attorney or
other agent shall be the person who seeks the right to inspection, the demand
under oath shall be accompanied by a power of attorney or such other writing
which authorizes the attorney or other agent to so act on behalf of the
stockholder. The demand under oath shall be directed to the Corporation at its
registered office in this State or at its principal place of business.

         The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list required by Section
1.10 or the books of the Corporation, or to vote in person or by proxy at any
meeting of the stockholders.

Directors, by resolution or resolutions, may create and issue, whether or not in
connection with the issue and sale of any shares of stock or other securities of
the Corporation, rights or options entitling the holders thereof to purchase
from the Corporation any shares of its capital stock of any class or classes or
any other securities of the Corporation, such rights or options to be evidenced
by or in such instrument or instruments as shall be approved by the Board of
Directors. The terms upon which, including the time or times, which may be
limited or unlimited in duration, at or within which, and the price or prices at
which, any such rights or options may be issued and any such shares or other
securities may be purchased from the Corporation upon the exercise of any such
right or option shall be such as shall be fixed and stated in the resolution or
resolutions adopted by the Board of Directors providing for the creation and
issue of such rights or options, and, in every case, set forth or incorporated
by reference in the instrument or instruments evidencing such rights or options.
In the absence of actual fraud in the transaction, the judgment of the directors
as to the consideration for the issuance of such rights or options and the
sufficiency thereof shall be conclusive. In case the shares of stock of the

otherwise provided therein, the acceptance of such resignation shall not be
necessary to make it effective.

         SECTION 2.05. VACANCIES AND NEWLY CREATED DIRECTORSHIPS. Vacancies and
newly created directorships resulting from any increase in the authorized number
of directors may be filled by a majority of the directors then in office, though
less than a quorum, or by a sole remaining director, in each case as such
director or directors may be directed by the stockholders of the Corporation,
and the directors so chosen shall hold office until their successors shall be
elected and qualified, or until their earlier resignation or removal, provided,
however, that the stockholders removing any director may at the same meeting
fill the vacancy caused by such removal, and provided further that if the
directors fail to fill any such vacancy, the stockholders may at any special
meeting called for such purpose, by written consent or otherwise, fill such
vacancy. When one or more directors shall resign from the Board, 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, in each
case as such directors may be directed by the stockholders of the Corporation,

certificate have been acquired by a bona fide purchaser; (2) files with the
Corporation a bond sufficient (in the judgment of the directors) or with respect
to institutional investors an agreement, to indemnify the Corporation against
any claim that may be made against it on account of the alleged loss or theft of
that certificate or the issuance of a new certificate; and (3) satisfies any
other requirements imposed by the directors that are reasonable under the
circumstances. A new certificate may be issued without requiring any bond when,
in the judgment of the directors, it is proper so to do.

Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the stockholders need be specified in any written waiver of
notice.

         Attendance of a person at a meeting of stockholders shall constitute a
waiver of notice of such meeting, 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.

of America, or by any rule, regulation, proclamation or executive order issued
under any such law, then 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; and any
action or meeting which shall be taken or held without notice to any such person
or without giving or without applying for a license or permit to give any such
notice to any such person with whom communication is made unlawful as aforesaid,
shall have the same force and effect as if such notice had been given as

Delaware, or under the provisions of the Certificate of Incorporation of the
Corporation or of these By-Laws. In the

of a certificate under any of the other sections of this title, the certificate

given to all persons entitled to receive notice except such persons with whom
communication is unlawful.

benefit the Corporation. The loan, guaranty 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 this Section contained shall be deemed to
