shareholders, whether annual or special, stating the time when and place where
it is to be held, shall be served either personally or by mail, not less than
fifteen nor more than fifty days before the meeting, upon each shareholder of
record entitled to vote at such meeting, and to any other shareholder to whom
the giving of notice may be required by law. Notice of a special meeting shall
also state the purpose or purposes for which the meeting is called, and shall
indicate that it is being issued by, or at the direction of, the person or
persons calling the meeting. If, at any meeting, action is proposed to be taken
that would, if taken, entitle shareholders to receive payment for their shares
pursuant to Statute, the notice of such meeting shall include a statement of
that purpose and to that effect. If mailed, such notice shall be directed to
each such shareholder at his address, as it appears on the records of the
shareholders of the Corporation, unless he shall have previously filed with the
Secretary of the Corporation a written request that notices intended for him be
mailed to some other address, in which case, it shall be mailed to the address
designated in such request.

(b) Notice of any meeting need not be given to any person who may become a
shareholder of record after the mailing of such notice and prior to the meeting,
or to any shareholder who attends such meeting, in person or by proxy, or to any
shareholder who, in person or by proxy, submits a signed waiver of notice either
before or after such meeting. Notice of any adjourned meeting of shareholders
need not be given, unless otherwise required by statute.

meetings in person or by proxy of shareholders holding of record a majority of
the total number of shares of the Corporation then issued and outstanding and
entitled to vote,

                                  By-Laws - 2
<PAGE>

shall be necessary and sufficient to constitute a quorum for the transaction of
any business. The withdrawal of any shareholder after the commencement of a
meeting shall have no effect on the existence of a quorum, after a quorum has
been established at such meeting.

(b) Despite the absence of a quorum at any annual or special meeting of
shareholders, the shareholders, by a majority of the votes cast by the holders
of shares entitled to vote thereon, may adjourn the meeting. At any such
adjourned meeting at which a quorum is present, any business may be transacted
at the meeting as originally called if a quorum had been present.

thereon.

(b) Except as otherwise provided by statute or by the Certificate of
Incorporation, at each meeting of shareholders, each holder of record of stock
of the Corporation entitled to vote thereat, shall be entitled to one vote for
each share of stock registered in his name on the books of the Corporation.

(c) Each shareholder entitled to vote or to express consent or dissent without a
meeting, may do so by proxy; provided, however, that the instrument authorizing
such proxy to act shall have been executed in writing by the shareholder
himself, or by his attorney-in-fact thereunto duly authorized in writing. No
proxy shall be valid after the expiration of eleven months from the date of its
execution, unless the person executing it shall have specified therein the
length of time it is to continue in force. Such instrument shall be exhibited to
the Secretary at the meeting and shall be filed with the records of the
Corporation.

<PAGE>

(d) Any resolution in writing, signed by all of the shareholders entitled to
vote thereon, shall be and constitute action by such shareholders to the effect
therein expressed, with the same force and effect as if the same has been duly
passed by unanimous vote at a duly called meeting of shareholders and such
resolution so signed shall be inserted in the Minute Book of the Corporation
under its proper date.

                       ARTICLE III - BOARD OF DIRECTORS

notice, whether before or after the meeting. Notice of any adjourned meeting
shall not be required to be given.

Section 5 - Chairman:

had been passed by unanimous vote at a duly called meeting of the Board.

Section 8 - Vacancies:

number of directors, or by reason of the death, resignation, disqualification,

removal was effected) or inability to act of any director, or otherwise, shall
be filled for the unexpired portion of the term by a majority vote of the
remaining directors, though less than a quorum, at any regular meeting or
special meeting of the Board of Directors called for that purpose.

Section 9 - Resignation:

<PAGE>

be in such form as shall be adopted by the Board of Directors, and shall be
numbered and registered in the order issued. They shall bear the holder's name
and the number of shares, and shall be signed by (i) the Chairman of the Board
or the President or a Vice President, and (ii) the Secretary or Treasurer, or
any Assistant Secretary or Assistant Treasurer, and shall bear the corporate
seal.

(b) No certificate representing shares shall be issued until the full amount of
consideration therefor has been paid, except as otherwise permitted by law.

(c) To the extent permitted by law, the Board of Directors may authorize the
issuance of certificates for fractions of a share which shall entitle the holder
to exercise voting rights, receive dividends and participate in liquidating
distributions, in proportion to the fractional holdings; or it may authorize the
payment in cash of the fair value of fractions of a share as of the time when
those entitled to receive such fractions are determined; or it may authorize the
issuance, subject to such conditions as may be permitted by law, or scrip in
registered or bearer form over the signature of an officer or agent of the
Corporation, exchangeable as therein provided for full shares, but such scrip
shall not entitle the holder to any rights of a shareholder, except as therein
provided.

Section 2 - Lost or Destroyed Certificates:

The holder of any certificate representing shares of the Corporation shall
immediately notify the Corporation of any loss or destruction of the certificate
representing the same. The Corporation may issue a new certificate in the place
of any certificate theretofore issued by it, alleged to have been lost or
destroyed. On production of such evidence of loss or destruction as the Board of
Directors in its discretion may require, the Board of Directors may, in its
discretion, require the owner of the lost or destroyed certificate, or his legal
representatives, to give the Corporation a bond in such sum as the Board may
direct, and with such surety or sureties as may be satisfactory to the Board, to
indemnify the Corporation against any claims, loss, liability or damage it may
suffer on account of the issuance of the new certificate. A new certificate may
be issued without requiring any such evidence or bond when, in the judgment of
the Board of Directors, it is proper to do so.

authenticity of the signature and of authority to transfer and of payment of
transfer taxes as the Corporation or its agents may require.

(b) The Corporation shall be entitled to treat the holder of record of any
shares as the absolute owner thereof for all purposes and, accordingly, shall
not be bound to recognize any legal, 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 expressly
provided by law.

Section 4 - Record Date:

Directors, except that the Board of Directors shall have no power to change the
quorum for meetings of shareholders or of the Board of Directors, or to change
any provisions of the by-laws with respect to the removal of directors or the
filling of vacancies in the Board resulting from the removal by the
shareholders. If any by-law regulating an impending election of directors is

suit or proceeding, or in connection with any appeal therein that such officer,
director or employee is liable for negligence or misconduct in the performance

other rights to which any officer or director or employee may be entitled apart
