Assistant Secretary or the transfer agent of the Corporation shall, after giving
such notice, make an affidavit stating that notice has been given, which shall

business to be properly brought before an annual meeting by a stockholder, such
stockholder must have given timely notice thereof in proper written form to the

tenth (10th) day following the day on which public announcement of the date of
such meeting is first made; provided further that for purposes of the annual
meeting of stockholders held following the end of the fiscal year ending on

deemed to be February 14.

                  (B) To be in proper written form, a stockholder's notice to
the Secretary must set forth as to each matter such stockholder proposes to
bring before the annual meeting (1) a brief description of the business desired

the meeting.

                  (iii) No business shall be conducted at the annual meeting of
stockholders except business brought before the annual meeting in accordance
with the procedures set forth in this Section 2.03, provided, however, that,
once business has been properly brought before the annual meeting in accordance
with such procedures, nothing in this Section 2.03 shall be deemed to preclude
discussion by any stockholder of any such business. If the chairman of an annual
meeting determines that business was not properly brought before the annual
meeting in accordance with the foregoing procedures, the chairman shall declare
to the meeting that the business was not properly brought before the meeting and
such business shall not be transacted.

                  (ii) In addition to any other applicable requirements, for a
nomination to be made by a stockholder, such stockholder must have given timely
notice thereof in proper written form to the Secretary of the Corporation.

                  (A) To be timely, a stockholder's notice shall be delivered to
the secretary at the principal executive offices of the corporation not less
than sixty (60) days nor more than ninety (90) days prior to the first
anniversary of the preceding year's annual meeting; provided, however, that in
the event that the date of the annual meeting is advanced by more than thirty
(30) days or delayed by more than sixty (60) days from such anniversary date,
notice by the stockholder to be timely must be delivered not earlier than the
(90th) day prior to such annual meeting and not later than the close of business

promulgated thereunder; and (2) as to the stockholder giving notice (v) the name
and record address of such stockholder, (w) the class or series and number of
shares of capital stock of the Corporation which are owned beneficially or of
record by such stockholder, (x) a description of all arrangements or
understandings between such stockholder and each proposed nominee and any other

defective nomination shall be disregarded.

                  Section 2.04. Adjournments.
                  ------------- ------------  Whenever a meeting of
stockholders, annual or special, is adjourned to another date, time or place,
notice need not be given of the adjourned meeting if the date, time and place
thereof are announced at the meeting at which the adjournment is taken. If the
adjournment is for more than 30 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 entitled to vote thereat. At the adjourned meeting,
any business may be transacted which might have been transacted at the original
meeting.

                  Section 2.05. Quorum.
                  ------------- ------  At each meeting of stockholders, except
where otherwise required by law, the Certificate of Incorporation or these
Bylaws, the holders of a majority of the outstanding shares of stock entitled to
vote on a matter at the meeting, present in person or represented by proxy,
shall constitute a quorum. For purposes of the foregoing, where a separate vote
by class or classes is required for any matter, the holders of a majority of the
outstanding shares of such class or classes, present in person or represented by
proxy, shall constitute a quorum to take action with respect to that vote on
that matter. Two or more classes or series of stock shall be considered a single
class if the holders thereof are entitled to vote together as a single class at
the meeting. In the absence of a quorum of the holders of any class of stock
entitled to vote on a matter, the meeting of such class may be adjourned from
time to time in the manner provided by these Bylaws until a quorum of such class
shall be so present or


                                      -4-
   9
represented. Shares of its own capital stock belonging on the record date for
the meeting 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; provided, however, that the
foregoing shall not limit the right of the Corporation to vote stock, including
but not limited to its own stock, held by it in a fiduciary capacity.

                  Section 2.06. Organization.
                  ------------- ------------  The Chairman of the Board shall
act as chairman at all meetings of stockholders at which he or she is present,
and as such chairman shall call such meetings of stockholders to order and
preside thereat. If the Chairman of the Board shall be absent from any meeting
of stockholders, the duties otherwise provided in this Section 2.06 to be
performed by him or her at such meeting, shall be performed at such meeting by a
chairman designated by the Board, or in the absence of such designation, by a
chairman chosen at the meeting. The Secretary of the Corporation shall act as
secretary at all meetings of the stockholders, but in his or her absence the
chairman of the meeting may appoint any person present to act as secretary of
the meeting.

                  Section 2.07. Inspectors of Elections.
                  ------------- -----------------------  Prior to any meeting of
stockholders, the Board, or a Chairman of the Board designated by the Board,
shall appoint one or more inspectors to act at such meeting and make a written
report thereof and may designate one or more persons as alternate inspectors to
replace any inspector who fails to act. If no inspector or alternate is able to
act at the meeting of stockholders, the person presiding at the meeting shall
appoint one or more inspectors to act at the meeting. Each inspector, before
entering upon the discharge of his or her duties, shall take and sign an oath
faithfully to execute the duties of inspector with strict impartiality and
according to the best of his or her ability. The inspectors shall ascertain the
number of shares outstanding and the voting power of each, determine the shares
represented at the meeting and the validity of proxies and ballots, count all
votes and ballots, determine and retain for a reasonable period a record of the
disposition of any challenges made to any determination by the inspectors and
certify their determination of the number of shares represented at the meeting
and their count of all votes and ballots. The inspectors may appoint or retain
other persons to assist them in the performance of their duties. The date and
time of the opening and closing of the polls for each matter upon which the
stockholders will vote at a meeting shall be announced at the meeting. No
ballot, proxy or vote, nor any revocation thereof or change thereto, shall be
accepted by the inspectors after the closing of the polls. In determining the
validity and counting of proxies and ballots, the inspectors shall be limited to
an examination of the proxies, any envelopes submitted therewith, any
information provided by a stockholder who submits a proxy by telegram, cablegram
or other electronic transmission from which it can be determined that the proxy
was authorized by the stockholder, ballots and the regular books and record of
the Corporation, and they may also consider other reliable information for the
limited purpose of reconciling proxies and ballots submitted by or on behalf of
banks, brokers, their nominees or similar persons which represent more votes
than the holder of a proxy is authorized by the record owner to cast or more
votes than the stockholder holds of record. If the inspectors consider other
reliable information for such purpose, they shall, at the time they make their
certification, specify the precise information considered by them,


                                      -5-
   10
including the person or persons from whom they obtained the information, when
the information was obtained, the means by which the information was obtained
and the basis for the inspectors' belief that such information is accurate and
reliable.

                  Section 2.08. Fixing of Record Date. The Board may fix a date
                  ------------- ---------------------
not more than sixty (60) days nor less than ten (10) days prior to the date of
any meeting of stockholders, as a record date for the determination of the
stockholders entitled to notice of and to vote at such meeting and any
adjournment thereof, and in such case such stockholders and only such
stockholders of record on the date so fixed shall be entitled to notice of, and
to vote at, such meeting and any adjournment thereof, notwithstanding any
transfer of any stock on the books of the Corporation after any such record date
fixed as aforesaid. No record date shall precede the date on which the Board
establishes such record date. The Secretary shall prepare and make or cause to
be prepared and made, at least ten (10) days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at such
meeting, arranged in alphabetical order and showing the address of each such
stockholder and the number of shares registered in the name of each such
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 (10) days prior to the meeting, either at a place, specified in
the notice of the meeting, within the city where the meeting is to be held, or,
if not so specified, at the place where the meeting is to be held. Such list
shall be produced and kept at the time and place of the meeting during the whole
time thereof, and subject to the inspection of any stockholder who may be
present.

                  Section 2.09. Voting; Proxies. Unless otherwise provided in
                  ------------- ---------------
the Certificate of Incorporation, each stockholder entitled to vote at any
meeting of stockholders shall be entitled to one vote for each share of stock
held by such stockholder which has voting power upon the matter in question. If
the Certificate of Incorporation provides for more or less than one vote for any
share on any matter, every reference in these Bylaws to a majority or other
proportion of shares of stock shall refer to such majority or other proportion
of the votes of such shares of stock. Each stockholder entitled to vote at a
meeting of stockholders may authorize another person or persons to act for such
stockholder by proxy, but no such proxy shall be voted or acted upon after three
years from its date, unless the proxy provides for a longer period. A duly
executed proxy shall be irrevocable if it states that it is irrevocable and if,
and only as long as, it is coupled with an interest sufficient in law to support
an irrevocable power, regardless of whether the interest with which it is
coupled is an interest in the stock itself or an interest in the Corporation
generally. A stockholder may revoke any proxy which is not irrevocable by
attending the meeting and voting in person or by filing an instrument in writing
revoking the proxy or another duly executed proxy bearing a later date with a
Secretary. Voting at meetings of stockholders need not be by written ballot

without cause at any time, unless otherwise provided in the resolution of the

to the contractual rights of such officer, if any, with the Corporation, but the

rights. Any vacancy occurring in any office of the Corporation by death,
resignation, removal or otherwise may be filled by the Board at any regular or
special meeting or by an officer authorized by the Board to appoint a person to
hold such office.

                  Section 5.03. Powers and Duties.

Board and any committees in a book to be kept for that purpose. The Board may
require any officer, agent or employee to give security for the faithful

                  Section 6.01. Stock Certificates; Uncertificated Shares.
                  ------------- ----------------------------------------- (a)
The shares of stock in the Corporation shall be represented by certificates,
provided that the Board of the Corporation may provide by resolution or
resolutions that some or all of any or all classes or series of its stock shall
be uncertificated shares. Any such resolution shall not apply to any such shares
represented by a certificate theretofore issued until such certificate is
surrendered to the Corporation. Notwithstanding the adoption of such a
resolution or resolutions by the Board of the Corporation, every holder of stock
represented by certificates, and upon request every holder of uncertificated
shares, shall be entitled to have a certificate signed by or in the name of the
Corporation by the Chairman of the Board or the President or a Vice President,
and by a Treasurer, Assistant Treasurer, Secretary or Assistant Secretary,
representing the number of shares of stock in the Corporation owned by such
holder. If such certificate is manually signed by one or more officers or
manually countersigned by a transfer agent or by a registrar, any other
signature on the certificate may be a facsimile. In case any officer, transfer
agent or registrar who has signed or whose facsimile signature has been placed
upon a certificate shall have ceased to be such officer, transfer agent or
registrar before such certificate is issued, it may be issued by the Corporation
with the same effect as if such person were such officer, transfer agent or
registrar at the date of issue. Certificates representing shares of stock of the
Corporation may bear such legends regarding restrictions on transfer or other
matters as any officer or officers of the Corporation may determine to be
appropriate and lawful.

                  (b) If the Corporation is authorized to issue more than one
class of stock or more than one series of any class, the powers, designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications or restrictions of
such preferences and/or rights shall be set forth in full or summarized on the
face or back of the certificate which the Corporation shall issue to represent
such class or series of stock, provided that, except as otherwise required by
law, in lieu of the foregoing requirements, there may be set forth on the face
or back of the certificate which the Corporation shall issue to represent such
class or series of stock a statement that the Corporation will furnish without
charge to each stockholder who so requests the powers, designations, preferences
and relative, participating, optional or other special rights of such class or
series of stock and the qualifications, limitations or restrictions of such
preferences and/or rights. Within a reasonable time after the issuance or
transfer of uncertificated shares of any class or series of stock, the
Corporation shall send to the registered owner thereof a written notice
containing the information required by law to be set forth or stated on
certificates representing shares of such class or series or a statement that the
Corporation will furnish without charge to each stockholder who so requests the
powers, designations, preferences and relative, participating, optional or other
special rights of such class or series and the qualifications, limitations or
restrictions of such preferences and/or rights.

                  (c) Except as otherwise expressly provided by law, the rights
and obligations of the holders of uncertificated shares and the rights and
obligations of the holders of certificates representing stock of the same class
and series shall be identical.

                  Section 6.02. Transfers of Stock.
                  ------------- ------------------ Transfers of stock shall be
made on the books of the Corporation by the person named in the certificate, or
by an attorney lawfully constituted in writing, and upon surrender and
cancellation of a certificate or certificates for a like number of shares of the
same class or series of stock, duly endorsed or accompanied by proper evidence
of succession, assignment or authority to transfer, and with such proof of the
authenticity of the signatures as the Corporation or its agents may reasonably
require and with all required stock transfer tax stamps affixed thereto and
canceled or accompanied by sufficient funds to pay such taxes.

                  Section 6.03. Lost Certificates.
                  ------------- ----------------- In case any certificate of
stock shall be lost, stolen or destroyed, the Board, in its discretion, or any
officer or officers thereunto duly authorized by the Board, may authorize the
issue of a substitute certificate in place of the certificate so lost, stolen or
destroyed; provided, however, that, in each such case, the applicant for a
substitute certificate shall furnish evidence to the Corporation, which it
determines in its discretion is satisfactory, of the loss, theft or destruction
of such certificate and of the ownership thereof, and also such security or
indemnity as may be required by it.

                  Section 6.04. Determination of Holders of Record for Certain
                  ------------- ----------------------------------------------
Purposes.
- -------- In order to determine the stockholders or other holders of securities
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 capital stock or other securities or for the purpose
of any other lawful action, the Board may fix, in advance, a record date, not
more than sixty (60) days prior to the date of payment of such dividend or other
distribution or allotment of such rights or the date when any such rights in
respect of any change, conversion or exchange of stock or securities may be
exercised, and in such case only holders of record on the date so fixed shall be
entitled to receive payment of such dividend or other distribution or to receive
such allotment of rights, or to exercise such rights, notwithstanding any
transfer of any stock or other securities on the books of the Corporation after
any such record date fixed as aforesaid. No record date shall precede the date
on which the Board establishes such record date.
