                                  Stockholders
                                  ------------

     Section 1.01 Annual Meeting. The Board of Directors by resolution shall
designate the time, place and date (which shall be, in the case of the first
annual meeting, not more than 13 months after the organization of the
Corporation and, in the case of all other annual meetings, not more than 13
months after the date of the last annual meeting) of the annual meeting of the
stockholders for the election of directors and the transaction of such other
business as may come before it.

     Section 1.02 Special Meetings. Special meetings of the stockholders, for
any purpose or purposes, may be called at any time by the Chairman, the
Vice-Chairman, the President, any Vice-President, the Treasurer or the Secretary
or by resolution of the Board of Directors and shall be called by the Secretary
upon receipt by the Secretary of a request to the Corporation in writing signed
by the holders of at least 35% of the Common Stock of the Corporation then
outstanding. Special meetings of stockholders shall be held at such place,
within or without the State of Delaware, as shall be fixed by the person or
persons calling the meeting and stated in the notice or waiver of notice of the
meeting.





     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 Article SIXTH of
the Certificate of Incorporation of the Corporation and Section 1.12 hereof)
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
original meeting. If the adjournment is for more than thirty 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 1.04 Quorum. At all meetings of the stockholders, the holders of
one-third of the stock issued and outstanding and entitled to vote thereat,
present in person or by proxy, shall constitute a quorum for the transaction of
any business.

     When a quorum is once present to organize a meeting, it is not broken by
the subsequent withdrawal of any stockholders.



                                      -2-






     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
meeting need not be by ballot. All elections and all other questions shall be
decided by a plurality of the votes cast, at a meeting at which a quorum is
present, except as expressly provided otherwise by the General Corporation Law
of the State of Delaware or the Certificate of Incorporation.

     Section 1.06 Voting Rights of Stockholders and Proxies. Each stockholder of
record entitled to vote in accordance with the laws of the State of Delaware,
the Certificate of Incorporation or these By-Laws, shall at every meeting of the
stockholders be entitled to one vote in person or by proxy for each share of
stock entitled to vote standing in his name on the 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



                                      -3-



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;

     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 entitled to notice of or to vote at any
meeting of 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



                                      -4-




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 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
who may be present. Upon the willful neglect or refusal of the directors to
produce such a list at any meeting for the election of directors, they shall be
ineligible for election to any office at such meeting.

     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



                                      -5-




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.

     Section 1.12 Consent in Lieu of Meeting. As provided in Article SIXTH of
the Certificate of Incorporation, any corporate action, with respect to which
the vote of the stockholders at a meeting thereof is required or permitted by
any provision of the General Corporation Law of the State of Delaware, the
Certificate of Incorporation of the Corporation, or these By-Laws, may be taken
without that vote and meeting, and that vote and meeting may be dispensed with,
if that corporate action has been consented to in writing by the holders of a
majority (or, if with respect to a particular corporate action the General
Corporation Law of the State of Delaware, the Certificate of Incorporation of
the Corporation or these By-Laws specifies a greater percentage, by the holders
of that percentage) of the stock that would have been entitled to vote upon that
action if a meeting were held. Prompt notice shall be given to all stockholders
of the taking of any corporate action pursuant to the provisions of that
paragraph unless that action has been consented to in writing by the holders of
all of the stock that would have been entitled to vote upon that action if a
meeting were held.

be managed by its Board of Directors.

     The Board of Directors, in addition to the powers and authority expressly
conferred upon it herein, by statute, by the Certificate of Incorporation of the
Corporation or otherwise, is hereby empowered to exercise all such powers as may
be exercised by the Corporation, except as expressly provided otherwise by the
statutes of the State of Delaware, by the Certificate of Incorporation of the
Corporation or by these By-Laws.

     Without prejudice to the generality of the foregoing, the Board of
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




                                      -7-




thereof shall be conclusive. In case the shares of stock of the Corporation to
be issued upon the exercise of such rights or options shall be shares having a
par value, the price or prices so to be received therefor shall not be less than
the par value thereof. In case the shares of stock so to be issued shall be
shares of stock without par value, the consideration therefor shall be
determined in the manner provided in Section 153 of the General Corporation Law
of the State of Delaware.

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
