shall be held for the election of directors at such date, time and place, either

transacted at the annual meeting.

            Section 1.2. Special Meetings. Special meetings of stockholders for
any purpose or purposes may be called at any time by the Board of Directors, or
by a committee of the Board of Directors which has been duly designated by the
Board of Directors, and whose powers and authority, as expressly provided in a
resolution of the Board of Directors, include the power to call such meetings,
but such special meetings may not be called by any other person or persons.

            Section 1.3. Notice of Meetings. Whenever stockholders are required
or permitted to take any action at a meeting, a written notice of the meeting
shall be given 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. Unless otherwise provided by law, the written notice of any meeting
shall be given not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting. If
mailed, such notice shall be deemed to be given when deposited in the mail,
postage prepaid, directed to the stockholder at his address as it appears on
the records of the corporation.

            Section 1.4. Adjournments. Any meeting of stockholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such 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 (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 of record entitled to vote at the meeting.



            Section 1.5. Quorum. At each meeting of stockholders, except where
otherwise provided by law or the Certificate of Incorporation or these by-laws,
the holders of a majority of the outstanding shares of stock entitled to vote at
the meeting, present in person or by proxy, shall constitute a quorum. In the
absence of a quorum, the stockholders so present may, by majority vote, adjourn
the meeting from time to time in the manner provided in Section 1.4 of these
by-laws until a quorum shall attend. Shares of its own 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 vole 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 1.6. Organization. Meetings of stockholders shall be
presided over by the Chairman of the Board, if any, or in his absence by the
Vice Chairman of the Board, if any, or in his absence by the President, or in
his absence by a Vice President, or in the absence of the foregoing persons by a
chairman designated by the Board of Directors, or in the absence of such
designation by a chairman chosen at the meeting. The Secretary shall act as
secretary of the meeting, but in his absence the chairman of the meeting may
appoint any person to act as secretary of the meeting.

            Section 1.7. Voting; Proxies. Except as otherwise provided by 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
him which has voting power upon the matter in question. Each stockholder
entitled to vote at a meeting of stockholders may authorize another person or
persons to act for him by proxy, but no such proxy shall be voted or acted upon
after three (3) 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 so long as, it is coupled with an interest
sufficient in law to support an irrevocable power. A stockholder may revoke any
proxy that 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 the Secretary of the corporation. Voting at
meetings of stockholders need not be by written ballot and need not be conducted
by inspectors unless the holders of a majority of the outstanding shares of all
classes of stock entitled to vote thereon present in person or by proxy at such
meeting shall so determine. At all meetings of stockholders for the election of
Directors a plurality of the votes cast shall be sufficient to elect. All other
elections and questions shall, unless otherwise provided by law or by the
Certificate of Incorporation or these by-laws, be decided by the vote of the
holders of a majority of the shares of stock entitled to vote thereon present in
person or represented by proxy at such meeting.

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
entitled to exercise any rights in respect of any change, conversion or exchange

may fix a record date, which record date shall not precede the date upon which
the resolution fixing the record date is adopted by the Board of Directors and

vote at any meeting of stockholders or adjournment thereof, shall not be more
than sixty (60) nor less than ten (10) days before the date of such meeting; (2)
in the case of determination of stockholders entitled to express consent to
corporate action in writing without a meeting, shall not be more than ten (10)
days from the date upon which the resolution fixing the record date is adopted
by the Board of Directors; and (3) in the case of any other action, shall not be
more than sixty (60) days prior to such other action. If no record date is
fixed: (a) the record date for determining stockholders entitled to notice of or
to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held; (b) the record date for determining stockholders entitled to express
consent to corporate action in writing without a meeting when no prior action of
the Board of Directors is required by law, shall be the first date on which any
signed written consent setting forth the action taken or proposed to be taken is
delivered to the corporation in accordance with applicable law; or, if prior
action by the Board of Directors is required by law, shall be at the close of
business on the day on which the Board of Directors adopts the resolution taking

shall prepare and make, at least ten (10) days before every meeting of
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.

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 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 the meeting is to be held.
The list shall also 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 is
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. The stock ledger shall be me only

corporation, or to vote in person or by proxy at any meeting of stockholders.

restricted by the Certificate of Incorporation, any action required or permitted
to be taken at any annual or special meeting of the stockholders may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

convened. Neither the business to be transacted at, nor the purpose of any

shall be void or voidable solely for this reason, or solely because the Director
or Officer is present at or participates in the meeting of the Board or
committee thereof which authorizes the contract or transaction, or solely
because his or their votes are counted for such purpose, if: (1) the material
facts as to his relationship or interest and as to the contract or transaction

thereof, or the stockholders. Common or interested Directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or
of a committee which authorizes the contract of transaction.
