the President and stated in the notice of the meeting. The purposes for which
the annual meeting is to be held, in addition to those prescribed by law, by

stockholders, stating the place, date and hour thereof, and the purposes for

calling the meeting at least seven days before the meeting to each stockholder
entitled to vote thereat and to each stockholder, who by law, by the Articles
of Organization or by these By-Laws is entitled to such notice, by leaving such
notice with him or at his residence or usual place of business, or by mailing
it postage prepaid and addressed to such stockholder at his address as it
appears upon the books of the corporation. No notice need be given to any
stockholder if a written waiver of notice, executed before or after the meeting
by the stockholder or his attorney thereunto authorized, is filed with the
records of the meeting.

                 6. VOTING AND PROXIES. Each stockholder shall have one vote

executed by one of them unless at or prior to exercise of the proxy the
corporation receives a specific written notice to the contrary from any one of
them.   A proxy purporting to be executed by or on behalf of a stockholder

larger vote is required by law, the Articles of Organization or these
By-laws, shall decide any matter to be voted on by the stockholders. Any
election by stockholders shall be determined by a plurality of the votes cast
by the stockholders entitled to vote at the election. No ballot shall be
required for such election unless requested by a stockholder present or
represented at the meeting and entitled to vote in the election. The
corporation shall not directly or indirectly vote any share of its stock.

                 8. ACTION WITHOUT MEETING. Any action to be taken by 
stockholders may be taken without a meeting if all stockholders entitled to 
vote on the matter consent to the action by a writing filed with the records 
of the meetings of stockholders. Such consent shall be treated for all 
purposes as a vote at a meeting.

the election of Directors, provided that the Directors of a class elected by
a particular class of stockholders may be removed only by the vote of the
holders of a majority of the shares of such class or (b) for cause by vote of
a majority of the Directors then in office. A Director may be removed for
cause only after reasonable notice and opportunity to be heard before the body
proposing to remove him.

                7. MEETINGS. Regular meetings of the Directors may be held 
without call or notice at such places and at such times the Directors may 
from time to time determine, provided that any Director who is absent when
such determination is made shall be given notice of the determination. A
regular meeting of the Directors may be held without a call or notice at the
same place as the annual meeting of stockholders, or the special meeting held
in lieu thereof, following such meeting of stockholders.
                Special meetings of the Directors may be held at any time and
place designated in a call by the President, Treasurer or two or more
Directors.

Director if a written waiver of notice, executed by him before or after the
meeting, is filed with the records of the meeting, or to any Director who
attends the meeting without protesting prior thereto or at its commencement
the lack of notice to him. A notice or waiver of notice of a Director's
meeting need not specify the purposes of the meeting.

which a quorum is present, the vote of a majority of those present, unless a
different vote is specified by law, by the Articles of Organization, or by
these By-Laws, shall be sufficient to decide such matter.

                 11. ACTION BY CONSENT. Any action by the Directors
may be taken without a meeting if a written consent thereto is signed by all
the Directors and filed with the records of the Directors' meetings Such
consent shall be treated as a vote of the Directors for all purposes.

                 12. COMMITTEES. The Directors may, by vote of a majority of
the Directors then in office, elect from their number an executive or other
committees and may by like vote delegate thereto some or all of their powers
except those which by law, the Articles of Organization or these By-Laws they
are prohibited from delegating. Except as the Directors may otherwise
determine, any such committee may make rules for the conduct of its business,

                  1. CERTIFICATES OF STOCK. Each stockholder shall be entitled 
to a certificate of the capital stock of the corporation in such form as may 
be prescribed from time to time by the Directors. The certificate shall be 
signed by the President or a Vice President, and by the Treasurer or an 
Assistant Treasurer, but when a certificate is countersigned by a transfer
agent or a registrar, other than a Director, officer or employee of the
corporation, such signatures may be facsimiles. In case any officer who has
signed or whose facsimile signature has been placed on such certificate shall
have ceased to be such officer before such certificate is issued, it may be
issued by the corporation with the same effect as if he were such officer at
the time of its issue.
                  Every certificate for shares of stock which are subject to 
any restriction on transfer pursuant to the Articles of Organization, the 
By-Laws or any agreement to which the corporation is a party, shall have 
                



   7
the restriction noted conspicuously on the certificate and shall also set forth
on the face or back either the full text of the restriction or a statement of
the existence of such restriction and a statement that the corporation will
furnish a copy to the holder of such certificate upon written request and
without charge. Every certificate issued when the corporation is authorized
to issue more than one class or series of stock shall set forth on its face
or back either the full text of the preferences, voting powers, qualifications
and special and relative rights of the shares of each class and series
authorized to be issued or a statement of the existence of such preferences,
powers, qualifications and rights, and a statement that the corporation will
furnish a copy thereof to the holder of such certificate upon written request
and without charge.

                 2. TRANSFERS. Subject to any restrictions on transfer which
may be set forth in this Article IV, shares of stock may be transferred on
the books of the Corporation or by the surrender to the Corporation or its
transfer agent of the certificate therefor properly endorsed or accompanied by 
written assignment and power of attorney properly executed, with necessary 
transfer stamp affixed, and with such proof of the authenticity of signature 
as the Corporation or its transfer agent may reasonably require. Except as may
be otherwise required by law, by the Articles of Organization or by these 
By-Laws, the Corporation shall be entitled to treat the record holder of stock 
as shown on its books as the owner of such stock for all purposes, including 
the payment of dividends and the right to vote with respect thereto, regardless 
of any transfer, pledge or other disposition of such stock, until the shares 
have been transferred on the books of the Corporation in accordance with the 
requirements of these By-Laws.
                 It shall be the duty of each stockholder to notify the 
Corporation of his post office address.

                 3. RECORD DATE. The Directors may fix in advance a
time of not more than sixty days preceding the date of any meeting of
stockholders, or the date for the payment of any dividend or the making of
any distribution to stockholders, or the last day on which the consent or
dissent of stockholders may be effectively expressed for any purpose, as the
record date for determining the stockholders having the right to notice of
and to vote at such meeting, and any adjournment thereof, or the right to
receive such dividend or distribution or the right to give such consent or
dissent.   In such case only stockholders of record on such record date shall
have such right, notwithstanding any transfer of stock on the books of the
corporation, after the record date. Without fixing such record date, the
Directors may for any of such purposes close the transfer books for all or
any part of such period.

                 4. REPLACEMENT OF CERTIFICATES. In case of the alleged loss 
or destruction or the mutilation of a certificate of stock, a duplicate   
certificate may be issued in place thereof, upon such terms as the Directors 
may prescribe.

the corporation, or at an office of its transfer agent or of the Clerk. Said 
copies and records need not all be kept in the same office. They shall be 
available at all reasonable times to the inspection of any stockholder for any 
proper purpose but not to secure a list of stockholders for the purpose of

to "control share acquisitions" of the corporation or of shares of the
corporation's capital stock within the meaning of said Chapter 110D.
