                               ARTICLE 1. OFFICES


     The principal office of the corporation shall be located at the principal
place of business or such other place as the Board of Directors ("Board") may
designate. The corporation may have such other offices, either within or without
the State of Delaware, as the Board may designate or as the business of the
corporation may require from time to time.


                             ARTICLE 2. SHAREHOLDERS


2.1  ANNUAL MEETING.

     The annual meeting of the shareholders shall be held at such date, time and
location as the Board may designate, for the purpose of electing Directors and
transacting such other business as may properly come before the meeting.

2.2  SPECIAL MEETINGS.

     The Chairman of the Board, the President or the Board may call special
meetings of the shareholders for any purpose. Further, a special meeting of the
shareholders shall be held if the holders of not less than 50% of all the votes
entitled to be cast on any issue proposed to be considered at such special
meeting have dated, signed and delivered to the Secretary one or more written
demands for such meeting, describing the purpose or purposes for which it is to
be held.

2.3  MEETINGS BY COMMUNICATION EQUIPMENT.

     Shareholders may participate in any meeting of the shareholders by any
means of communication by which all persons participating in the meeting can
hear each other during the meeting. Participation by such means shall constitute
presence in person at a meeting.

<PAGE>

2.4  DATE, TIME AND PLACE OF MEETING.

     Except as otherwise provided herein, all meetings of shareholders,
including those held pursuant to demand by shareholders as provided herein,
shall be held on such date and at such time and place, within or without the
State of Delaware, designated by or at the direction of the Board.

2.5  NOTICE OF MEETING.

     Written notice stating the place, day and hour of the meeting and, in the
case of a special meeting, the purpose or purposes for which the meeting is
called shall be given by or at the direction of the Board, the Chairman of the
Board, the President or the Secretary to each shareholder entitled to notice of
or to vote at the meeting not less than 10 nor more than 60 days before the
meeting. Such notice may be transmitted by mail, private carrier, personal
delivery or communications equipment which transmits a facsimile of the notice
to like equipment which receives and reproduces such notice. If such notice is
mailed, it shall be deemed effective when deposited in the official government
mail, first-class postage prepaid, properly addressed to the shareholder at such
shareholder's address as it appears in the corporation's current record of
shareholders. Notice given in any other manner shall be deemed effective when
dispatched to the shareholder's address, telephone number or other number
appearing on the records of the corporation.

2.6  WAIVER OF NOTICE.

     Whenever any notice is required to be given to any shareholder under the
provisions of these Bylaws, the Certificate of Incorporation or the Delaware
General Corporation Law, a waiver thereof in writing, signed by the person or
persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting, shall be deemed equivalent to the
giving of such notice. Further, notice of the time, place and purpose of any
meeting will be deemed to be waived by any shareholder by attendance thereat in
person or by proxy, unless such shareholder at the beginning of the meeting
objects to holding the meeting or transacting business at the meeting.

2.7  FIXING OF RECORD DATE FOR DETERMINING SHAREHOLDERS.

     For the purpose of determining shareholders entitled (a) to notice of or to
vote at any meeting of shareholders or any adjournment thereof, (b) to demand a
special meeting, or (c) to receive payment of any dividend, or in order to make
a determination of shareholders for any other purpose, the Board may fix a
future date as the record date for any such determination. Such record date
shall be not more than 60 days, and in case of a meeting of shareholders not
less than 10 days prior to the date on which the particular action requiring
such determination is to be taken. If no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting, the
record date shall be the day immediately preceding the date on which notice of
the meeting is first given to shareholders. Such a determination shall apply to
any adjournment of the meeting unless the Board fixes a new record date. If no
record date is set for the determination of shareholders entitled to receive
payment of any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, the record date shall be the date the Board
adopted the resolution relating thereto or authorized such action.

2.8  VOTING RECORD.

     At least 10 days before each meeting of shareholders, an alphabetical list
of the shareholders entitled to notice of such meeting shall be made, with the
address of and number of shares held by each shareholder. This record shall be
kept at the principal office of the corporation for 10 days prior to such
meeting, and shall be kept open at such meeting, for the inspection of any
shareholder or any shareholder's agent.


                                        3
<PAGE>

2.9  QUORUM.

     A majority of the votes entitled to be cast on a matter by the holders of
shares that, pursuant to the Certificate of Incorporation or the Delaware
General Corporation Law, are entitled to vote and be counted collectively upon
such matter, represented in person or by proxy, shall constitute a quorum of
such shares at a meeting of shareholders. If less than a majority of such votes
are represented at a meeting, a majority of the votes so represented may adjourn
the meeting from time to time without further notice if the new date, time or
place is announced at the meeting before adjournment. Any business may be
transacted at a reconvened meeting that might have been transacted at the
meeting as originally called, provided a quorum is present or represented
thereat. Once a share is represented for any purpose at a meeting other than
solely to object to holding the meeting or transacting business thereat, it is
deemed present for quorum purposes for the remainder of the meeting and any
adjournment thereof (unless a new record date is or must be set for the
adjourned meeting) notwithstanding the withdrawal of enough shareholders to
leave less than a quorum.

2.10 MANNER OF ACTING.

     If a quorum is present, action on a matter shall be approved if the votes
cast in favor of the action by the shares entitled to vote and be counted
collectively upon such matter exceed the votes cast against such action by the
shares entitled to vote and be counted collectively thereon, unless the
Certificate of Incorporation or the Delaware General Corporation Law requires a
greater number of affirmative votes.

2.11 PROXIES.

     A shareholder may vote by proxy executed in writing by the shareholder or
by his or her attorney-in-fact or agent. Such proxy shall be effective when
received by the Secretary or other officer or agent authorized to tabulate
votes. A proxy shall become invalid 3 years after the date of its execution,
unless otherwise provided in the proxy. A proxy with respect to a specified
meeting shall entitle the holder thereof to vote at any reconvened meeting
following adjournment of such meeting but shall not be valid after the final
adjournment thereof.


                                        4
<PAGE>


2.12 VOTING OF SHARES.

     Except as otherwise provided in the Certificate of Incorporation, each
outstanding share entitled to vote with respect to a matter submitted to a
meeting of shareholders shall be entitled to one vote upon such matter.

2.13 VOTING FOR DIRECTORS.

     Each shareholder entitled to vote at an election of Directors may vote, in
person or by proxy, the number of shares owned by such shareholder for as many
persons as there are Directors to be elected and for whose election such
shareholder has a right to vote. Unless otherwise provided in the Certificate of
Incorporation, the candidates elected shall be those receiving the largest
number of votes cast, up to the number of Directors to be elected. Cumulative
voting for Directors is prohibited.

2.14 ACTION BY SHAREHOLDERS WITHOUT A MEETING.

     Any action which could be taken at a meeting of the shareholders may be
taken without a meeting if one or more written consents setting forth the action
so taken are 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
and delivered to the corporation. If not otherwise fixed by the Board, the
record date for determining shareholders entitled to take action without a
meeting is the first date on which a signed written consent setting forth the
action taken or proposed to be taken is delivered to the corporation. If no
record date has been fixed by the Board of Directors and prior action by the
Board of Directors is required by this chapter, the record date for determining
shareholders entitled to consent to corporate action in writing without a
meeting shall be at the close of business on the day on which the Board of
Directors adopts the resolution taking such prior action. Action taken by
written consent of shareholders without a meeting is effective when all required
consents are in the possession of the corporation, unless the consent specifies
a later effective date. Any such consent shall be inserted in the minute book as
if it were the minutes of a meeting of the shareholders. Prompt notice of the
taking of the corporate action without a meeting by LESS THAN UNANIMOUS WRITTEN
CONSENT shall be given to those shareholders or members, as the case may be, who
have not consented in writing.

     The Board shall be composed of no fewer than three and no more than eleven

resigns, or is removed, his or her term of office shall expire at the next
annual meeting of shareholders; provided, however, that a Director shall
continue to serve until his or her successor is elected and qualified or until
there is a decrease in the authorized number of Directors. Directors need not be
shareholders of the corporation or residents of the State of Delaware and need
not meet any other qualifications.

3.3  CHAIRMAN OF THE BOARD.

     The Board shall elect a director as chairman, which director shall be known
as the Chairman of the Board. The Chairman of the Board shall preside at all
meetings of the Board, and in addition, shall perform the following functions:

          a.   general planning and management of all functions of the Board of
               Directors;
          b.   organization of Board committees and assignments thereto;
          c.   recruitment and nomination of additional or successor directors;
          d.   determining the agenda for all Board meetings; and
          e.   development of Board members as appropriate for effectiveness on
behalf of shareholders.

The Chairman of the Board shall serve for a term of one (1) year  and shall be
elected at the annual meeting; PROVIDED, HOWEVER, that the initial Chairman of
the Board shall be elected by Written Consent of the Board of Directors and
shall serve until the next ensuing annual meeting.

3.6  MEETINGS BY COMMUNICATIONS EQUIPMENT.

     Members of the Board or any committee designated by the Board may
participate in a meeting of such Board or committee by, or conduct the meeting
through the use of, any means of communication by which all Directors
participating in the meeting can hear each other during the meeting.
Participation by such means shall constitute presence in person at a meeting.

3.7  NOTICE OF SPECIAL MEETINGS.

     Notice of a special Board or committee meeting stating the place, day and
hour of the meeting shall be given to a Director in writing or orally. Neither
the business to be transacted at, nor the purpose of, any special meeting need
be specified in the notice of such meeting.

     3.7.3      DELIVERY BY PRIVATE CARRIER.

     If notice is given by private carrier, the notice shall be deemed effective
when dispatched to a Director at his or her address shown on the records of the
corporation at least three days before the meeting.

     3.7.4      FACSIMILE NOTICE.

     If notice is delivered by wire or wireless equipment which transmits a

be deemed effective if personally given to the Director at least two days before

3.8  WAIVER OF NOTICE.

     3.8.1      IN WRITING.

     Whenever any notice is required to be given to any Director under the
provisions of these Bylaws, the Certificate of Incorporation or the Delaware
General Corporation Law, a waiver thereof in writing, signed by the person or
persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting, shall be deemed equivalent to the
giving of such notice. Neither the business to be transacted at, nor the purpose
of, any regular or special meeting of the Board or any committee designated by
the Board need be specified in the waiver of notice of such meeting.

     3.8.2      BY ATTENDANCE.

     A Director's attendance at or participation in a Board or committee meeting
shall constitute a waiver of notice of such meeting, unless the Director at the
beginning of the meeting, or promptly upon his or her arrival, objects to
holding the meeting or transacting business thereat and does not thereafter vote
for or assent to action taken at the meeting.

permitted by applicable law as it presently exists or may hereafter be amended,
any person who was or is made or is threatened to be made a party to or is
otherwise involved in any action, suit or proceeding, whether civil, criminal,
administrative, or investigative (a "Proceeding") by reason of the fact that he,
or a person for whom he is the legal representative, is or was a director,
officer, employee or agent of the corporation or is or was serving at the

directors or officers, or between the corporation and any other corporation,
partnership, association, or other organization in which one or more of its
directors or officers are directors or officers, or have a financial interest,
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 of
Directors or committee thereof which authorizes the contract or transaction, or

transaction are disclosed or are known to the Board of Directors or the
committee, and the Board of Directors or committee in good faith authorizes the

quorum; or (2) the material facts as to his relationship or interest and as to
the contract or transaction are disclosed or are known to the shareholders
entitled to vote thereon, and the contract or transaction is specifically
approved in good faith by vote of the shareholders; or (3) the contract or
transaction is fair as to the corporation as of the time it is authorized,
approved or ratified, by the Board of Directors, a committee thereof, or the
shareholders.  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 or transaction.
