                         CERTIFICATE OF INCORPORATION

     Section 1.1  CONTENTS. The name, location of principal office and purposes
of the Corporation shall be as set forth in its Certificate of Incorporation.
These Bylaws, the powers of the Corporation and of its Directors and
stockholders, and all matters concerning the conduct and regulation of the
business of the Corporation shall be subject to such provisions in regard
thereto, if any, as are set forth in said Certificate of Incorporation. The
Certificate of Incorporation is hereby made a part of these Bylaws.

     Section 1.2  CERTIFICATE IN EFFECT. All references in these Bylaws to the
Certificate of Incorporation shall be construed to mean the Certificate of
Incorporation of the Corporation as from time to time amended, including (unless
the context shall otherwise require) all certificates and any agreement of
consolidation or merger filed pursuant to the Delaware General Corporation Law,
as amended.

                                   ARTICLE 2

                           MEETINGS OF STOCKHOLDERS

     Section 2.1  PLACE. All meetings of the stockholders may be held at such
place either within or without the State of Delaware as shall be designated from
time to time by the Board of Directors, the Chairman of the Board of Directors
or the President and stated in the notice of the meeting or in any duly executed
waiver of notice thereof.

     Section 2.2  ANNUAL MEETING. Annual meetings of stockholders, shall be held
on the second Tuesday of April in each year, if not a legal holiday, and, if a
legal holiday, then on the next secular day following, at 10:00 A.M., or at such
other date and time as shall be designated from time to time by the Board of
Directors, the Chairman of the Board of Directors or the President and stated in
the notice of the meeting. If such annual meeting has not been held on the day
herein provided therefor, a special meeting of the stockholders in lieu of the
annual meeting may be held, and any business transacted or elections held at
such special meeting shall have the same effect as if transacted or held at the
annual meeting, and in such case all references in these Bylaws, except in this
Section 2.2, to the annual meeting of the stockholders shall be deemed to refer
to such special meeting.

     Section 2.3  SPECIAL MEETINGS. Except as otherwise required by law and
subject to the rights of the holders of the Preferred Stock, special meetings of
stockholders of the Corporation may be called only by (i) the Board of Directors
pursuant
<PAGE>

to a resolution approved by a majority of the entire Board, (ii) the
Corporation's President or (iii) the Chairman of the Board of the Corporation.
Special meetings of the stockholders may be held at such time and date, and at
such place as shall be designated by the Board of Directors and set forth in the
notice of meeting required pursuant to Section 2.4. Notwithstanding anything
contained in these Bylaws to the contrary, this Section 2.3 shall not be
altered, amended or repealed except by an affirmative vote of the holders of at
least eighty percent (80%) of the combined voting power of the outstanding
shares of all capital stock entitled to vote for the election of directors. Only
such business as is set forth in the notice of a special meeting may be
transacted at such Special Meeting.

     Section 2.4  NOTICE OF MEETINGS.  A written notice of all meetings of
stockholders stating the place, date and hour of the meeting and, in the case of
a special meeting, the purpose or purposes for which the special meeting is
called, shall be given to each stockholder entitled to vote at such meeting.
Except as otherwise provided by law, such notice shall be given not less than
ten nor more than sixty days before the date of the meeting.  Business
transacted at any special meeting of stockholders shall be limited to the
purposes stated in the notice.

     Section 2.5  AFFIDAVIT OF NOTICE.  An affidavit of the Secretary or an
Assistant Secretary or the transfer agent of the Corporation that notice of a
stockholders meeting has been given shall, in the absence of fraud, be prima
facie evidence of the facts stated therein.

     Section 2.6  QUORUM.  The holders of a majority of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
Certificate of Incorporation.  If, however, such quorum shall not be present or
represented by proxy at any meeting of the stockholders, the stockholders
entitled to vote thereat, present in person or represented by proxy, shall have
power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, except as hereinafter provided, until a quorum
shall be present or represented.  At such adjourned meeting at which a quorum
shall be present or represented any business may be transacted which might have
been transacted at the original meeting.  If the adjournment is for more than
thirty 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 2.7  VOTING REQUIREMENTS. When a quorum is present at any meeting,
the vote of the holders of a majority of the stock having voting power present
in person or represented by proxy shall decide any question brought before such
meeting, unless the question is one upon which by express provision of any
applicable statute or of the Certificate of Incorporation, a different vote is
required in which case such express provision shall govern and control the
decision of such question.

                                      -2-

     Section 2.8  PROXIES AND VOTING.  Unless otherwise provided in the
Certificate of Incorporation, each stockholder shall at every meeting of the
stockholders be entitled to one vote in person or by proxy for each share of the
capital stock having voting power held by such stockholder, but no proxy shall
be voted on after three years from its date, unless the proxy provides for a
longer period.  Persons holding stock in a fiduciary capacity shall be entitled
to vote the shares so held, and persons whose stock is pledged shall be entitled
to vote the pledged shares, unless in the transfer by the pledgor on the books
of the Corporation he shall have expressly empowered the pledgee to vote said
shares, in which case only the pledgee, or his proxy, may represent and vote
such shares.  Shares of the capital stock of the Corporation owned by the
Corporation shall not be voted, directly or indirectly.

     Section 2.9  NO STOCKHOLDER ACTION WITHOUT MEETING. Any action required or
permitted to be taken by the stockholders of the Corporation shall be taken at a
duly called annual or special meeting of such holders and may not be taken by
any consent in writing by such holders. Notwithstanding anything contained in
these Bylaws to the contrary, this Section 2.9 shall not be altered, amended or
repealed except by an affirmative vote of the holders of at least eighty percent
(80%) of the combined voting power of the outstanding shares of all capital
stock entitled to vote for the election of directors.

     Section 2.10 STOCKHOLDER LIST. The officer who has charge of the stock
ledger of the Corporation shall prepare and make, at least ten 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.
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 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. The original or duplicate stock ledger shall be the only evidence as to
who are the stockholders entitled to examine such list, the stock ledger or the
books of the Corporation, or to vote in person or by proxy at any meeting of
stockholders.

     Section 2.11 RECORD DATE. In order that the Corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express 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 of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty nor less than ten days before the date of
such meeting, nor more than sixty days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the

                                      -3-
<PAGE>

Board of Directors may fix a new record date for the adjourned meeting. If no
record date is fixed by the Board of Directors:

     (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
by the Board of Directors is necessary, shall be the day on which the first
written consent is expressed.

     (c)  The record date for determining stockholders for any other purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto.

     Section 2.12  ADVANCE NOTICE OF STOCKHOLDER PROPOSED BUSINESS AT ANNUAL
MEETING. At an annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before the meeting. To be properly
brought before an annual meeting, business must be either (a) specified in the
notice of meeting (or any supplement thereto) given by or at the direction of
the Board of Directors, (b) otherwise properly brought before the meeting by or
at the direction of the Board of Directors, or (c) otherwise properly brought
before the meeting by a stockholder. In addition to any other applicable
requirements, for business to be properly brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
Corporation, not less than 120 days nor more than 150 days prior to the first
anniversary of the date of the Corporation's notice of annual meeting provided
with respect to the previous year's annual meeting; provided, that if no annual
meeting was held in the previous year or the date of the annual meeting has been
changed to be more than 30 calendar days earlier than or 60 calendar days after
such anniversary, notice by the stockholder, to be timely, must be so received
not more than 90 days nor later than the later of (i) 60 days prior to the
annual meeting or (ii) the close of business on the 10th day following the day
on which such notice of the date of the annual meeting was mailed or such public
disclosure was made, whichever first occurs. A stockholder's notice to the
Secretary shall set forth as to each matter the stockholder proposes to bring
before the annual meeting (i) a brief description of the business desired to be
brought before the annual meeting and the reasons for conducting such business
at the annual meeting, (ii) the name and record address of the stockholder
proposing such business, (iii) the class and number of shares of the Corporation
which are beneficially owned by the stockholder, and (iv) any material interest
of the stockholder in such business.

     Notwithstanding anything in the Bylaws to the contrary, no business shall
be conducted at the annual meeting except in accordance with the procedures set
forth in this Section 12; provided, however, that nothing in this Section 12
shall be deemed to

                                      -4-
<PAGE>

preclude discussion by any stockholder of any business properly brought before
the annual meeting in accordance with said procedure.

     The Chairman of an annual meeting shall, if the facts warrant, determine
and declare to the meeting that business was not properly brought before the
meeting in accordance with the provisions of this Section 12, and if he should
so determine, he shall so declare to the meeting and any such business not
properly brought before the meeting shall not be transacted.

     Notwithstanding anything contained in the Bylaws to the contrary, this
Section 12 shall not be altered, amended or repealed except by an affirmative
vote of the holders of at least eighty percent (80%) of the combined voting
power of the outstanding shares of all capital stock entitled to vote for the
election of directors.

                                   ARTICLE 3

                                   DIRECTORS

     Section 3.1  NUMBER; ELECTION AND TERM OF OFFICE. The Corporation's Board
shall consist of not less than three nor more than twelve members, with the
exact number to be fixed from time to time in accordance with a resolution
adopted by a majority of the entire Board. No decrease in the number of
directors shall have the effect of shortening the term of any incumbent
director. The Board shall be divided into three classes. The number of directors
elected to each class shall be as nearly equal in number as possible. Each
director in the first class shall be elected to an initial term expiring at the
next ensuing annual meeting of stockholders, each director in the second class
shall be elected to an initial term expiring at the annual meeting of
stockholders held one year thereafter and each director in the third class shall
be elected to an initial term expiring at the annual meeting of stockholders
held one year thereafter, in each case until his or her successor is duly
elected and qualified or until his or her earlier resignation, death, incapacity
or removal from office. Upon the expiration of the initial terms of office for
each class of directors, the successor directors of each class shall be elected
for a full term of three years, to serve until their successors are duly elected
and qualified or until their earlier resignation, death, incapacity or removal
from office. The Board shall apportion any increase or decrease in the number of
directors among the classes as nearly equal in number as possible.

     Section 3.2  DUTIES.  The business of the Corporation shall be managed by
or under the direction of its Board of Directors which may exercise all such
powers of the Corporation and do all such lawful acts and things as are not by
statute or by the Certificate of Incorporation or by these Bylaws directed or
required to be exercised or done by the stockholders.

     Section 3.3  COMPENSATION. Unless otherwise restricted by the Certificate
of Incorporation or these Bylaws, the Board of Directors shall have the
authority to fix the compensation of Directors. The Directors may be paid their
expenses, if any, of

                                      -5-
<PAGE>

attendance at each meeting of the Board of Directors and may be paid a fixed sum
for attendance at each meeting of the Board of Directors or a stated salary as
Directors. No such payment shall preclude any Director from serving the
Corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

     Section 3.4  RELIANCE ON BOOKS.  A member of the Board of Directors or a
member of any committee designated by the Board of Directors shall, in the
performance of his duties, be fully protected in relying in good faith upon the
books of account or reports made to the Corporation by any of its officers, or
by an independent certified public accountant, or by an appraiser selected with
reasonable care by the Board of Directors or by any committee, or in relying in
good faith upon other records of the Corporation.

     Section 3.5  STOCKHOLDER NOMINATIONS FOR DIRECTOR CANDIDATES. Only persons
who are nominated in accordance with the following procedures shall be eligible
for election as directors. Nominations of persons for election to the Board of
Directors of the Corporation may be made at a meeting of stockholders by or at
the direction of the Board of Directors by any nominating committee or person
appointed by the Board of Directors or by any stockholder of the Corporation
entitled to vote for the election of directors at the meeting who complies with
the notice procedures set forth in this Section 3.5. Such nominations, other
than those made by or at the direction of the Board of Directors, shall be made
pursuant to timely notice in writing to the Secretary of the Corporation. To be
timely, a stockholder's notice shall be delivered to or mailed and received at
the principal executive offices of the Corporation, not less than 120 days nor
more than 150 days prior to the first anniversary of the date of the
Corporation's notice of annual meeting provided with respect to the previous
year's annual meeting; provided, that if no annual meeting was held in the
previous year or the date of the annual meeting has been changed to be more than
30 calendar days earlier than or 60 calendar days after such anniversary, notice
by the stockholder, to be timely, must be so received not more than 90 days nor
later than the later of (i) 60 days prior to the annual meeting or (ii) the
close of business on the 10th day following the day on which such notice of the
date of the annual meeting was mailed or such public disclosure was made,
whichever first occurs. Such stockholder's notice to the Secretary shall set
forth (a) as to each person whom the stockholder proposes to nominate for
election or re-election as a director, (i) the name, age, business address and
residence address of the person, (ii) the principal occupation or employment of
the persons, (iii) the class and number of shares of capital stock of the
Corporation which are beneficially owned by the person, (iv) the consent of each
nominee to serve as a director of the Corporation if so elected, and (v) any
other information relating to the person that is required to be disclosed in
solicitations for proxies for election of directors pursuant to Rule 14a under
the Securities Exchange Act of 1934, as amended; and (b) as to the stockholder
giving the notice, (i) the name and record address of that stockholder, and (ii)
the class and number of shares of capital stock of the Corporation which are
beneficially owned by the stockholder. The Corporation may require any proposed
nominee to furnish such other information as may reasonably be required by the
Corporation to determine the eligibility

                                      -6-
<PAGE>

of such proposed nominee to serve as director of the Corporation. No person
shall be eligible for election as a director of the Corporation unless nominated
in accordance with the procedures set forth herein.

     Section 10.1   THIRD PARTY ACTIONS.  The Corporation shall indemnify any
Director or officer of the Corporation, and may indemnify any other person, who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the Corporation) by
reason of the fact that such person is or was a Director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorney's
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by the person in connection with such action, suit or proceeding if the
person acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the Corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.  The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he or she reasonably believed to be in
or not opposed to the best interests of the Corporation, and, with respect to
any criminal action or proceeding, had reasonable cause to believe that his or
her conduct was unlawful.

     Section 10.2   DERIVATIVE ACTIONS.  The Corporation shall indemnify any
Director or officer of the Corporation, and may indemnify any other person, who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action or suit by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that such person is or was a
Director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
the person in connection with the defense or settlement of such action or suit
if the person acted in good faith and in a manner he or she reasonably believed
to be in or not opposed to the best interests of the Corporation and except that
no indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

     Section 10.3   EXPENSES.  To the extent that any present or former Director
or officer of the Corporation has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in Sections 10.1 and 10.2,
or in defense of any

                                     -15-

claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection therewith.

     Section 10.4   AUTHORIZATION.  Any indemnification under Sections 10.1 and
10.2 (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
present or former Director, officer, employee or agent is proper in the
circumstances because such person has met the applicable standard of conduct set
forth in Sections 10.1 and 10.2.  Such determination shall be made, with respect
to a person who is a Director or officer at the time of such determination, (a)
by a majority vote of the Directors who are not parties to such action, suit or
proceeding ("disinterested Directors"), even though less than a quorum, or (b)
by a committee of disinterested Directors designated by a majority vote of the
disinterested Directors, even though less than a quorum, or (c) if there are no
disinterested Directors,, or if the disinterested Directors so direct, by
independent legal counsel in a written opinion, or (d) by the stockholders.

     Section 10.5   ADVANCE PAYMENT OF EXPENSES.  Expenses (including attorneys'
fees) incurred by a present or former executive officer or Director in defending
a civil, criminal, administrative or investigative action, suit or proceeding
shall be paid by the Corporation in advance of the final disposition of such
action, suit or proceeding upon receipt of an undertaking by or on behalf of
such officer or Director to repay such amount if it shall ultimately be
determined that he or she is not entitled to be indemnified by the Corporation
as authorized in this Article 10.  Such expenses incurred by other officers,
employees and agents may be so paid upon such terms and conditions, if any, as
the Board of Directors deems appropriate.

     Section 10.6   NON-EXCLUSIVENESS.  The indemnification and advancement of
expenses provided by this Article 10 shall not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may be
entitled under any bylaw, agreement, vote of stockholders or disinterested
Directors or otherwise, both as to action in his or her official capacity and as
to action in another capacity while holding such office, and shall continue as
to a person who has ceased to be a Director, officer, employee or agent and
shall inure to the benefit of the heirs, executors and administrators of such a
person.

     Section 10.7   INSURANCE.  The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a Director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against such person and incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the Corporation would
have the power to indemnify the person against such liability under the
provisions of this Article 10.

request of such constituent corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, in the same manner as hereinabove provided for any person who is or
was a Director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
