                      SECOND AMENDED AND RESTATED BYLAWS



ARTICLE I - STOCKHOLDERS

    Section 1.   Annual Meeting.

    An annual meeting of the stockholders, for the election of directors to
succeed those whose terms expire and for the transaction of such other business
as may properly come before the meeting, shall be held at such place, on such
date, and at such time as the Board of Directors shall fix each year.


    Section 2.   Special Meetings.

    Subject to the rights of the holders of any class or series of preferred
stock of the Corporation, special meetings of stockholders of the Corporation
may be called only by the Board of Directors pursuant to a resolution adopted by
a majority of the total number of directors authorized.  Special meetings of the
stockholders may be held at such place within or without the State of Delaware
as may be stated in such resolution.

    Section 3.   Notice of Meetings.

    Written notice of the place, date, and time of all meetings of the
stockholders shall be given, not less than ten (10) nor more than sixty (60)
days before the date on which the meeting is to be held, to each stockholder
entitled to vote at such meeting, except as otherwise provided herein or
required by law (meaning, here and hereinafter, as required from time to time by
the Delaware General Corporation Law or the Certificate of Incorporation of the
Corporation, as amended and restated from time to time).

    When a meeting is adjourned to another place, date or time, written notice
need not be given of the adjourned meeting if the place, date and time thereof
are announced at the meeting at which the adjournment is taken; provided,
however, that if the date of any adjourned meeting is more than thirty (30) days
after the date for which the meeting was originally noticed, or if a new record
date is fixed for the adjourned meeting, written notice of the place, date, and
time of the adjourned meeting shall be given in conformity herewith.  At any
adjourned meeting, any business may be transacted which might have been
transacted at the original meeting.

    Section 4.   Quorum.

    At any meeting of the stockholders, the holders of a majority of all of the
shares of the stock entitled to vote at the meeting, present in person or by
proxy, shall constitute a quorum for all purposes, unless or except to the
extent that the presence of a larger number may be required by law. Where a
separate vote by a class or classes is required, a majority of the shares of
such class or

                                       1

<PAGE>

classes present in person or represented by proxy shall constitute a quorum
entitled to take action with respect to that vote on that matter.

     If a quorum shall fail to attend any meeting, the chairman of the meeting
or the holders of a majority of the shares of stock entitled to vote who are
present, in person or by proxy, may adjourn the meeting to another place, date,
or time.

     Section 5.   Organization and Conduct of Business.

     The Chairman of the Board of Directors or, in his or her absence, the Chief
Executive Officer of the Corporation or, in his or her absence, the President
or, in his or her absence, such person as the Board of Directors may have
designated, shall call to order any meeting of the stockholders and shall
preside at and act as chairman of the meeting.  In the absence of the Secretary
of the Corporation, the secretary of the meeting shall be such person as the
chairman of the meeting appoints.  The chairman of any meeting of stockholders
shall determine the order of business and the procedures at the meeting,
including such regulation of the manner of voting and the conduct of discussion
as he or she deems to be appropriate.

     Section 6.    Notice of Stockholder Business and Nominations.

     A.   Annual Meetings of Stockholders.

          Nominations of persons for election to the Board of Directors and the
proposal of business to be considered by the stockholders may be made at an
annual meeting of stockholders (a) pursuant to the Corporation's notice of
meeting, (b) by or at the direction of the Board of Directors or (c) by any
stockholder of the Corporation who was a stockholder of record at the time of
giving of notice provided for in this Section, who is entitled to vote at the
meeting and who complies with the notice procedures set forth in this Section.


     B.   Special Meetings of Stockholders.

     Only such business shall be conducted at a special meeting of stockholders
as shall have been brought before the meeting pursuant to the notice of meeting
given pursuant to Section 2 above. Nominations of persons for election to the
Board of Directors may be made at a special meeting of stockholders at which
directors are to be elected (a) by or at the direction of the Board of Directors
or (b) provided that the Board of Directors has determined that directors shall
be elected at such meeting, by any stockholder of the Corporation who is a
stockholder of record at the time of giving of notice of the special meeting,
who shall be entitled to vote at the meeting and who complies with the notice
procedures set forth in this Section.

     C.   Certain Matters Pertaining to Stockholder Business and Nominations.

          (1)  For nominations or other business to be properly brought before
an annual meeting by a stockholder pursuant to clause (c) of paragraph A of this
Section or a special meeting pursuant to paragraph B of this Section, the
stockholder must have given timely notice thereof in writing to the Secretary of
the Corporation and such other business must otherwise be a proper matter for
stockholder action. To be timely, a stockholder's notice pertaining to an annual
meeting

                                       2

<PAGE>

shall be delivered to the Secretary at the principal executive offices of the
Corporation not later than the close of business on the sixtieth (60) day nor
earlier than the close of business on the ninetieth (90th) day 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 more than thirty (30)
days before or more than sixty (60) days after such an anniversary date, notice
by the stockholder to be timely must be so delivered not earlier than the close
of business on the ninetieth (90) day prior to such annual meeting and not later
than the close of business on the later of the sixtieth (60th) day prior to such
annual meeting or the close of business on the tenth (10th) day following the
day on which public announcement of the date of such meeting is first made by
the Corporation. Such stockholder's notice for an annual meeting or a special
meeting shall set forth: (a) as to each person whom the stockholder proposes to
nominate for election or reelection as a director, all information relating to
such person that is required to be disclosed in solicitations of proxies for
election of directors, or is otherwise required, in each case, pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as amended (the
"Exchange Act") (including such person's written consent to being named in the
proxy statement as a nominee and to serving as a director if elected); (b) as to
any other business that the stockholder proposes to bring before the meeting, a
brief description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting and any material interest in
such business of such stockholder and the beneficial owner, if any, on whose
behalf the proposal is made; and (c) as to the stockholder giving the notice and
the beneficial owner, if any, on whose behalf the nomination or proposal is made
(i) the name and address of such stockholder, as they appear on the
Corporation's books, and of such beneficial owner and (ii) the class and number
of shares of the Corporation that are owned beneficially and held of record by
such stockholder and such beneficial owner. A stockholder shall also comply with
all applicable requirements of the Exchange Act (or any successor provision),
and the rules and regulations thereunder with respect to the matters set forth
in these Bylaws.


          (2)  Notwithstanding anything in the second sentence of paragraph C
(1) of this Section to the contrary, in the event that the number of directors
to be elected to the Board of Directors of the Corporation is increased and
there is no public announcement by the Corporation naming all of the nominees
for director or specifying the size of the increased Board of Directors at least
seventy (70) days prior to the first anniversary of the preceding year's annual
meeting (or, if the annual meeting is held more than thirty (30) days before or
sixty (60) days after such anniversary date, at least seventy (70) days prior to
such annual meeting), a stockholder's notice required by this Section shall also
be considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive office of the Corporation not later than the close of
business on the tenth (10th) day following the day on which such public
announcement is first made by the Corporation.

          (3)  In the event the Corporation calls a special meeting of
stockholders for the purpose of electing one or more directors to the Board of
Directors, any such stockholder may nominate a person or persons (as the case
may be), for election to such position(s) as specified in the Corporation's
notice of meeting, if the stockholder's notice required by paragraph C(1) of
this Section shall be delivered to the Secretary at the principal executive
offices of the Corporation not earlier than the ninetieth (90th) day prior to
such special meeting nor later than the close of business on the later of the
sixtieth (60th) day prior to such special meeting, or the tenth (10th) day
following

                                       3

<PAGE>

the day on which public announcement is first made of the date of the special
meeting and of the nominees proposed by the Board of Directors to be elected at
such meeting.

     D.   General.

          (1)  Only such persons who are nominated in accordance with the
procedures set forth in this Section shall be eligible to serve as directors and
only such business shall be conducted at a meeting of stockholders as shall have
been brought before the meeting in accordance with the procedures set forth in
this Section. Except as otherwise provided by law or these Bylaws, the chairman
of the meeting shall have the power and duty to determine whether a nomination
or any business proposed to be brought before the meeting was made or proposed,
as the case may be, in accordance with the procedures set forth in this Section
and, if any proposed nomination or business is not in compliance herewith, to
declare that such defective proposal or nomination shall be disregarded.

          (2)  For purposes of this Section, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission pursuant to Section 13,
14 or 15(d) of the Exchange Act.

          (3)  Notwithstanding the foregoing provisions of this Section, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to the matters set
forth herein. Nothing in this Section shall be deemed to affect any rights (i)
of stockholders to request inclusion of proposals in the Corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act or (ii) of the holders
of any series of Preferred Stock to elect directors under specified
circumstances.

     Section 7.   Proxies and Voting.

          At any meeting of the stockholders, every stockholder entitled to vote
may vote in person or by proxy authorized by an instrument in writing or by a
transmission permitted by law filed in accordance with the procedure established
for the meeting. Any copy, facsimile telecommunication or other reliable
reproduction of the writing or transmission created pursuant to this Section may
be substituted or used in lieu of the original writing or transmission for any
and all purposes for which the original writing or transmission could be used,
provided that such copy, facsimile telecommunication or other reproduction shall
be a complete reproduction of the entire original writing or transmission.

          All voting, including on the election of directors but excepting where
otherwise required by law, may be by voice vote.  Any vote not taken by voice
shall be taken by ballots, each of which shall state the name of the stockholder
or proxy voting and such other information as may be required under the
procedure established for the meeting.  The Corporation may, and to the extent
required by law, shall, in advance of any meeting of stockholders, appoint one
or more inspectors to act at the meeting and make a written report thereof.  The
Corporation may designate one or more persons as alternate inspectors to replace
any inspector who fails to act.  If

                                       4

<PAGE>

no inspector or alternate is able to act at a meeting of stockholders, the
person presiding at the meeting may, and to the extent required by law, shall,
appoint one or more inspectors to act at the meeting. Each inspector, before
entering upon the discharge of his duties, shall take and sign an oath
faithfully to execute the duties of inspector with strict impartiality and
according to the best of his ability.

     Except as otherwise provided in the terms of any class or series of
Preferred Stock of the Corporation, all elections at any meeting of stockholders
shall be determined by a plurality of the votes cast, and except as otherwise
required by law, all other matters determined by stockholders at a meeting shall
be determined by a majority of the votes cast affirmatively or negatively.

     Section 8.   Action Without Meeting.

     Any action required or permitted to be taken by the stockholders of the
Corporation may be effected only at a duly called annual or special meeting of
stockholders of the Corporation and may not be effected by written consent.

     Section 9.   Stock List.

     A complete list of stockholders entitled to vote at any meeting of
stockholders, arranged in alphabetical order for each class of stock and showing
the address of each such stockholder and the number of shares registered in his
or her name, shall be open to the examination of any such 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 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 stock list shall also be kept at the place of the meeting during the
whole time thereof and shall be open to the examination of any such stockholder
who is present.  Such list shall presumptively determine the identity of the
stockholders entitled to vote at the meeting and the number of shares held by
each of them.


                         ARTICLE II - BOARD OF DIRECTORS

     Section 1. General Powers, Number, Election, Tenure and Qualification.

     A.   The business and affairs of the Corporation shall be managed by or
under the direction of its Board of Directors.

     B.   Subject to the rights of the holders of any series of Preferred Stock
then outstanding to elect additional directors under specified circumstances,
the number of directors shall be fixed from time to time exclusively by the
Board of Directors pursuant to a resolution adopted by a majority of the Board.

                                       5

<PAGE>

     C.   On or prior to the Effective Time, as defined in Article FOURTH of the
Corporation's Restated Certificate of Incorporation, the Board of Directors of
the Corporation shall divide the directors into three classes, as nearly equal
in number as reasonably possible, with the term of office of the first class to
expire at the annual meeting of stockholders or any special meeting in lieu
thereof in 2001, the term of office of the second class to expire at the annual
meeting of stockholders or any special meeting in lieu thereof in 2002, and the
term of office of the third class to expire at the annual meeting of
stockholders or any special meeting in lieu thereof in 2003. At each annual
meeting of stockholders or special meeting in lieu thereof following such
initial classification, directors elected to succeed those directors whose terms
expire shall be elected for a term of office to expire at the third succeeding
annual meeting of stockholders or special meeting in lieu thereof after their
election and until their successors are duly elected and qualified.

     Section 2.   Vacancies and Newly Created Directorships.

     Subject to the rights of the holders of any series of Preferred Stock then
outstanding, newly created directorships resulting from any increase in the
authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the directors
then in office even though less than a quorum, or by a sole remaining director.
In the event of any increase or decrease in the authorized number of directors,
(i) each director then serving as such shall nevertheless continue as a director
of the class of which he is a member until the expiration of his current term or
his prior death, retirement, removal or resignation and (ii) the newly created
or eliminated directorships resulting from such increase or decrease shall if
reasonably possible be apportioned by the Board of Directors among the three
classes of directors so as to ensure that no one class has more than one
director more than any other class.  To the extent reasonably possible,
consistent with the foregoing rule, any newly created directorships shall be
added to those classes whose terms of office are to expire at the latest dates
following such allocation and newly eliminated directorships shall be subtracted
from those classes whose terms of office are to expire at the earliest dates
following such allocation, unless otherwise provided for from time to time by
resolution adopted by a majority of the directors then in office, although less
than a quorum.  In the event of a vacancy in the Board of Directors, the
remaining directors, except as otherwise provided by law, may exercise the
powers of the full Board of Directors until the vacancy is filled.

     Section 3.   Resignation and Removal.

     Any director may resign at any time upon written notice to the Corporation
at its principal place of business or to the Chairman of the Board, Chief
Executive Officer, President or Secretary.  Such resignation shall be effective
upon receipt unless it is specified to be effective at some other time or upon
the happening of some other event.  Subject to the rights of the holders of any
series of Preferred Stock then outstanding, any director, or the entire Board of
Directors, may be removed from office at any time only for cause.  A director
may be removed for cause by the holders of a majority of the shares of the
Corporation then entitled to vote at an election of a director and only after a
reasonable notice and opportunity to be heard before the stockholders.

                                       6

<PAGE>

     Section 4.   Regular Meetings.

     Regular meetings of the Board of Directors shall be held at such place or
places, on such date or dates, and at such time or times as shall have been
established by the Board of Directors and publicized among all directors.  A
written notice of each regular meeting shall not be required.

     Section 5.   Special Meetings.

     Special meetings of the Board of Directors may be called by the Chairman of
the Board of Directors or the Chief Executive Officer, and shall be called by
the Secretary if requested by a majority of the Board of Directors, and shall be
held at such place, on such date, and at such time as he or she or they shall
fix.  Notice of the place, date, and time of each such special meeting shall be
given to each director by whom it is not waived by mailing written notice not
less than three (3) days before the meeting or orally, by telegraph, telex,
cable or telecopy given not less than twenty-four (24) hours before the meeting.
Unless otherwise indicated in the notice thereof, any and all business may be
transacted at a special meeting.

     Section 6.   Quorum.

     At any meeting of the Board of Directors, a majority of the total number of
members of the Board of Directors shall constitute a quorum for all purposes.
If a quorum shall fail to attend any meeting, a majority of those present may
adjourn the meeting to another place, date, or time, without further notice or
waiver thereof.

     Section 7.   Action by Consent.

     Unless otherwise restricted by the Certificate of Incorporation or these
Bylaws, any action required or permitted to be taken at any meeting of the Board
of Directors or of any committee thereof may be taken without a meeting, if all
members of the Board or committee, as the case may be, consent thereto in
writing, and the writing or writings are filed with the minutes of proceedings
of the Board or committee.

     Section 8.   Participation in Meetings By Conference Telephone.

     Members of the Board of Directors, or of any committee thereof, may
participate in a meeting of such Board or committee by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other and such participation shall
constitute presence in person at such meeting.

     Section 9.  Conduct of Business.

     At any meeting of the Board of Directors, business shall be transacted in
such order and manner as the Board may from time to time determine, and all
matters shall be determined by the vote of a majority of the directors present,
except as otherwise provided herein or required by law.

                                       7

     Section 10.  Powers.

     The Board of Directors may, except as otherwise required by law, exercise
all such powers and do all such acts and things as may be exercised or done by
the Corporation, including, without limiting the generality of the foregoing,
the unqualified power:


          (1)  To declare dividends from time to time in accordance with law;

          (2)  To purchase or otherwise acquire any property, rights or
               privileges on such terms as it shall determine;

          (3)  To authorize the creation, making and issuance, in such form as
               it may determine, of written obligations of every kind,
               negotiable or non-negotiable, secured or unsecured, to borrow
               funds and guarantee obligations, and to do all things necessary
               in connection therewith;

          (4)  To remove any officer of the Corporation with or without cause,
               and from time to time to devolve the powers and duties of any
               officer upon any other person for the time being;

          (5)  To confer upon any officer of the Corporation the power to
               appoint, remove and suspend subordinate officers, employees and
               agents;

          (6)  To adopt from time to time such stock, option, stock purchase,

    Section 2.   Waiver of Notice.

    A written waiver of any notice, signed by a stockholder, director, officer,

given to such stockholder, director, officer, employee or agent.  Neither the
business nor the purpose of any meeting need be specified in such a waiver.
Attendance of a director or stockholder at a meeting without protesting prior
thereto or at its commencement the lack of notice shall also constitute a waiver

            ARTICLE VII - INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 1.   Right to Indemnification.

    Each person who was or is made a party or is threatened to be made a party
to or is otherwise involved (including, without limitation, as a witness) in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was a director or an officer
of the Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, or of a
partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "Indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a

                                       14

<PAGE>

director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than such law permitted
the Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such Indemnitee in connection therewith; provided, however, that,
except as provided in Section 3 of this Article with respect to proceedings to
enforce rights to indemnification or as otherwise required by law, the
Corporation shall not be required to indemnify or advance expenses to any such
Indemnitee in connection with a proceeding (or part thereof) initiated by such
Indemnitee unless such proceeding (or part thereof) was authorized by the Board
of Directors of the Corporation.

     Section 2.  Right to Advancement of Expenses.

     The right to indemnification conferred in Section 1 of this Article shall
include the right to be paid by the Corporation the expenses (including
attorney's fees) incurred in defending any such proceeding in advance of its
final disposition; provided, however, that, if the Delaware General Corporation
Law requires, an advancement of expenses incurred by an Indemnitee in his
capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such Indemnitee, including, without limitation,
service to an employee benefit plan) shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such Indemnitee, to repay all
amounts so advanced if it shall ultimately be determined by final judicial
decision from which there is no further right to appeal that such Indemnitee is
not entitled to be indemnified for such expenses under this Section 2 or
otherwise.  The rights to indemnification and to the advancement of expenses
conferred in Sections 1 and 2 of this Article shall be contract rights and such
rights shall continue as to an Indemnitee who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the Indemnitee's
heirs, executors and administrators.  Any repeal or modification of any of the
provisions of this Article shall not adversely affect any right or protection of
an Indemnitee existing at the time of such repeal or modification.

     Section 3.  Right of Indemnitees to Bring Suit.

     If a claim under Section 1 or 2 of this Article is not paid in full by the
Corporation within sixty (60) days after a written claim has been received by
the Corporation, except in the case of a claim for an advancement of expenses,
in which case the applicable period shall be twenty (20) days, the Indemnitee
may at any time thereafter bring suit against the Corporation to recover the
unpaid amount of the claim.  If successful in whole or in part in any such suit,
or in a suit brought by the Corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the Indemnitee shall also be entitled
to be paid the expenses of prosecuting or defending such suit.  In (i) any suit
brought by the Indemnitee to enforce a right to indemnification hereunder (but
not in a suit brought by the Indemnitee to enforce a right to an advancement of
expenses) it shall be a defense that, and (ii) in any suit brought by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the Corporation shall be entitled to recover such expenses upon a
final adjudication that, the Indemnitee has not met any applicable standard for

                                       15

<PAGE>

indemnification set forth in the Delaware General Corporation Law.  Neither the
failure of the Corporation (including its board of directors, independent legal
counsel, or its stockholders) to have made a determination prior to the
commencement of such suit that indemnification of the Indemnitee is proper in
the circumstances because the Indemnitee has met the applicable standard of
conduct set forth in the Delaware General Corporation Law, nor an actual
determination by the Corporation (including its board of directors, independent
legal counsel, or its stockholders) that the Indemnitee has not met such
applicable standard of conduct, shall create a presumption that the Indemnitee
has not met the applicable standard of conduct or, in the case of such a suit
brought by the Indemnitee, be a defense to such suit.  In any suit brought by
the Indemnitee to enforce a right to indemnification or to an advancement of
expenses hereunder, or brought by the Corporation to recover an advancement of
expenses pursuant to the terms of an undertaking, the burden of proving that the
Indemnitee is not entitled to be indemnified, or to such advancement of
expenses, under this Article or otherwise shall be on the Corporation.

     Section 4.  Non-Exclusivity of Rights.

     The rights to indemnification and to the advancement of expenses conferred
in this Article shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, the Corporation's Certificate of
Incorporation as amended from time to time, these Bylaws, any agreement, any
vote of stockholders or disinterested directors or otherwise.

     Section 5.  Insurance.

     The Corporation may maintain insurance, at its expense, to protect itself
and any director, officer, employee or agent of the Corporation or another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the Corporation would have the power
to indemnify such person against such expense, liability or loss under the
Delaware General Corporation Law.

     Section 6.  Indemnification of Employees and Agents of the Corporation.

     The Corporation may, to the extent authorized from time to time by the
Board of Directors, grant rights to indemnification and to the advancement of
expenses to any employee or agent of the Corporation to the fullest extent of
the provisions of this Article with respect to the indemnification and
advancement of expenses of directors and officers of the Corporation.

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 or
committee thereof which

                                       16

    Board of Directors or the committee, and the Board or committee in good
    faith authorizes the contract or transaction by the affirmative votes of a
    majority of the disinterested directors, even though the disinterested
    directors be less than a quorum; or

           (b)   The material facts as to his or her relationship or interest
    and as to the contract or transaction are disclosed or are known to the
    stockholders entitled to vote thereon, and the contract or transaction is
    specifically approved in good faith by vote of the stockholders; or

           (c)   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 stockholders.

    Section 2.   Quorum.

    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

the seal may be kept and used by the Treasurer or by an Assistant Secretary or
Assistant Treasurer.

    Section 3.   Reliance upon Books, Reports and Records.

    Each director, each member of any committee designated by the Board of
Directors, and each officer of the Corporation shall, in the performance of his
or her duties, be fully protected in relying in good faith upon the books of
account or other records of the Corporation and upon such information, opinions,
reports or statements presented to the Corporation by any of its officers or
employees, or committees of the Board of Directors so designated, or by any
other person as to matters which such director or committee member reasonably
believes are within such other person's professional or expert competence and
who has been selected with reasonable care by or on behalf of the Corporation.
