                                 Stockholders
                                 ------------

     SECTION 1.  Annual Meeting.  The annual meeting of stockholders (any such
                 --------------
meeting being referred to in these By-laws as an "Annual Meeting") shall be held
at the hour, date and place within or without the United States which is fixed
by the majority of the Board of Directors, the Chairman of the Board, if one is
elected, or the President, which time, date and place may subsequently be
changed at any time by vote of the Board of Directors.  If no Annual Meeting has
been held for a period of thirteen months after the Corporation's last Annual
Meeting, a special meeting in lieu thereof may be held, and such special meeting
shall have, for the purposes of these By-laws or otherwise, all the force and
effect of an Annual Meeting.  Any and all references hereafter in these By-laws
to an Annual Meeting or Annual Meetings also shall be deemed to refer to any
special meeting(s) in lieu thereof.

     SECTION 2.  Special Meetings.  Except as otherwise required by law and
                 ----------------
subject to the rights, if any, of the holders of any series of preferred stock,
special meetings of the stockholders of the Corporation may be called only by
the President, the Chief Executive Officer, the Chairman of the Board, if one is
elected, or the Board of Directors pursuant to a resolution approved by the
affirmative vote of a majority of the directors then in office.

     SECTION 3.  Notice of Stockholder Business and Nominations.
                 ----------------------------------------------

     (a) Annual Meetings of Stockholders.
         -------------------------------

          (1)  Nominations of persons for election to the Board of Directors of
     the Corporation and the proposal of business to be considered by the
     stockholders may be made at an Annual Meeting (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
     By-law, who is entitled to vote at the meeting and who complied with the
     notice procedures set forth in this By-law.


          (2) For nominations or other business to be properly brought before an
     Annual Meeting by a stockholder pursuant to clause (c) of paragraph (a)(1)
     of this By-law, the stockholder must have given timely notice thereof in
     writing to the Secretary of the Corporation, such other business must be a
     proper matter for stockholder action, and such stockholder be present at
     such meeting, either in person or by representative. To be timely, a
     stockholder's notice shall be delivered to the Secretary at the principal
     executive offices of the Corporation not later than the close of business
     on the 90th day nor earlier than the close of business on the 120th 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 30 days before or more than 60 days after such anniversary date,
     notice by the stockholder to be timely must be so delivered not earlier
     than the close of business on the 120th day prior to such Annual Meeting
     and not later than the close of business on the later of the 90th day prior
     to such Annual Meeting or the 10th day following the day on which public
     announcement of the date of such meeting is first made.  Notwithstanding
     anything to the contrary provided herein, for the first Annual Meeting
     following the initial public offering of common stock of the Corporation, a
     stockholder's notice shall be timely if delivered to, or mailed to and
     received by, the Corporation at its principal executive office not later
     than the close of business on the later of the 90th day prior to the
     scheduled date of such Annual Meeting or the 10th day following the day on
     which public announcement of the date of such Annual Meeting is first made
     or sent by the Corporation.  In no event shall the public announcement of
     an adjournment of an Annual Meeting commence a new time period for the
     giving of a stockholder's notice as described above.  Such stockholder's
     notice 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 in an election contest, or is
     otherwise required, in each case pursuant to Regulation 14A under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act") and Rule
     14a-11 thereunder (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, any material interest in such business of such stockholder and the
     beneficial owner, if any, on whose behalf the proposal is made, and the
     names and addresses of other stockholders known by the stockholder
     proposing such business to support such proposal, and the class and number
     of shares of the Corporation's capital stock beneficially owned by such
     other stockholders; 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 which are owned beneficially and of
     record by such stockholder and such beneficial owner.

                                       2


          (3) Notwithstanding anything in the second sentence of paragraph
     (a)(2) of this By-law 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 naming all of the nominees
     for director or specifying the size of the increased Board of Directors
     made by the Corporation at least 100 days prior to the first anniversary of
     the preceding year's Annual Meeting, a stockholder's notice required by
     this By-law 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 offices of the
     Corporation not later than the close of business on the 10th day following
     the day on which such public announcement is first made by the Corporation.

     (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 Corporation's notice of meeting.  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 pursuant to the
Corporation's notice of meeting (a) by or at the direction of the Board of
Directors or (b) by any stockholder of the Corporation who is a stockholder of
record at the time of giving of notice provided for in this By-law, who shall be
entitled to vote at the meeting and who complies with the notice procedures set
forth in this By-law.  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 (a)(2) of
this By-law shall be delivered to the Secretary at the principal executive
offices of the Corporation not earlier than the close of business on the 120th
day prior to such special meeting and not later than the close of business on
the later of the 90th day prior to such special meeting or the 10th day
following 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.  In no event shall the public announcement of an
adjournment of a special meeting commence a new time period for the giving of a
stockholder's notice as described above.

     (c)  General.
          -------

          (1)  Only such persons who are nominated in accordance with the
     procedures set forth in this By-law 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 By-law.  If the Board of Directors or a
     designated committee thereof determines that any stockholder proposal or
     nomination was not made in a timely fashion in accordance with the
     provisions of this By-law or that the information provided in a
     stockholder's notice does not satisfy the information requirements of this
     By-law in any material respect, such proposal or nomination shall not be
     presented for action at the Annual Meeting in question.  If neither the
     Board of Directors nor such committee makes a determination as to the

                                       3


     validity of any stockholder proposal or nomination in the manner set forth
     above, the presiding officer of the Annual Meeting shall determine whether
     the stockholder proposal or nomination was made in accordance with the
     terms of this By-law.  If the presiding officer determines that any
     stockholder proposal or nomination was not made in a timely fashion in
     accordance with the provisions of this By-law or that the information
     provided in a stockholder's notice does not satisfy the information
     requirements of this By-law in any material respect, such proposal or
     nomination shall not be presented for action at the Annual Meeting in
     question.  If the Board of Directors, a designated committee thereof or the
     presiding officer determines that a stockholder proposal or nomination was
     made in accordance with the requirements of this By-law, the presiding
     officer shall so declare at the Annual Meeting and ballots shall be
     provided for use at the meeting with respect to such proposal or
     nomination.

          (2) For purposes of this By-law, "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 (including, without limitation, a Form 8-K) pursuant to Section
     13, 14 or 15(d) of the Exchange Act.

          (3) Notwithstanding the foregoing provisions of this By-law, 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 in this By-law.  Nothing in this By-law shall be deemed
     to affect any rights of (i) stockholders to request inclusion of proposals
     in the Corporation's proxy statement pursuant to Rule 14a-8 under the
     Exchange Act or (ii) the holders of any series of preferred stock to elect
     directors under specified circumstances.

     SECTION 4.  Matters to be Considered at Special Meetings.  Only those
                 --------------------------------------------
matters set forth in the notice of the special meeting may be considered or
acted upon at a special meeting of stockholders of the Corporation, unless
otherwise provided by law.

     SECTION 5.  Notice of Meetings; Adjournments.  A written notice of each
                 --------------------------------
Annual Meeting stating the hour, date and place of such Annual Meeting shall be
given by the Secretary or an Assistant Secretary (or other person authorized by
these By-laws or by law) not less than 10 days nor more than 60 days before the
Annual Meeting, to each stockholder entitled to vote thereat and to each
stockholder who, by law or under the Certificate of Incorporation of the
Corporation (as the same may hereafter be amended and/or restated, the
"Certificate") or under these By-laws, is entitled to such notice, by delivering
such notice to him or by mailing it, postage prepaid, addressed to such
stockholder at the address of such stockholder as it appears on the
Corporation's stock transfer books.  Such notice shall be deemed to be given
when hand delivered to such address or deposited in the mail so addressed, with
postage prepaid.

                                       4


     Notice of all special meetings of stockholders shall be given in the same
manner as provided for Annual Meetings, except that the written notice of all
special meetings shall state the purpose or purposes for which the meeting has
been called.

     Notice of an Annual Meeting or special meeting of stockholders need not be
given to a stockholder if a written waiver of notice is signed before or after
such meeting by such stockholder or if such stockholder attends such meeting,
unless such attendance was for the express purpose of objecting at the beginning
of the meeting to the transaction of any business because the meeting was not
lawfully called or convened.  Neither the business to be transacted at, nor the
purpose of, any Annual Meeting or special meeting of stockholders need be
specified in any written waiver of notice.

     The Board of Directors may postpone and reschedule any previously scheduled
Annual Meeting or special meeting of stockholders and any record date with
respect thereto, regardless of whether any notice or public disclosure with
respect to any such meeting has been sent or made pursuant to Section 3 of this
Article I of these By-laws or otherwise.   In no event shall the public
announcement of an adjournment, postponement or rescheduling of any previously
scheduled meeting of stockholders commence a new time period for the giving of a
stockholder's notice under Section 3 of this Article I of these By-laws.

     When any meeting is convened, the presiding officer may adjourn the meeting
if (a) no quorum is present for the transaction of business, (b) the Board of
Directors determines that adjournment is necessary or appropriate to enable the
stockholders to consider fully information which the Board of Directors
determines has not been made sufficiently or timely available to stockholders,
or (c) the Board of Directors determines that adjournment is otherwise in the
best interests of the Corporation.  When any Annual Meeting or special meeting
of stockholders is adjourned to another hour, date or place, notice need not be
given of the adjourned meeting other than an announcement at the meeting at
which the adjournment is taken of the hour, date and place to which the meeting
is adjourned; provided, however, that if the adjournment is for more than 30
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote thereat and each stockholder who, by law or under the
Certificate or these By-laws, is entitled to such notice.

     SECTION 6.  Quorum.  A majority of the shares entitled to vote, present in
                 ------
person or represented by proxy, shall constitute a quorum at any meeting of
stockholders.  If less than a quorum is present at a meeting, the holders of
voting stock representing a majority of the voting power present at the meeting
or the presiding officer may adjourn the meeting from time to time, and the
meeting may be held as adjourned without further notice, except as provided in
Section 5 of this Article I.  At such adjourned meeting at which a quorum is
present, any business may be transacted which might have been transacted at the
meeting as originally noticed.  The stockholders present at a duly constituted
meeting may continue to

                                       5


transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.

     SECTION 7.  Voting and Proxies.  Stockholders shall have one vote for each
                 ------------------
share of stock entitled to vote owned by them of record according to the books
of the Corporation, unless otherwise provided by law or by the Certificate.
Stockholders may vote either in person or by written proxy, but no proxy shall
be voted or acted upon after three years from its date, unless the proxy
provides for a longer period.  Proxies shall be filed with the Secretary of the
meeting before being voted.  Except as otherwise limited therein or as otherwise
provided by law, proxies shall entitle the persons authorized thereby to vote at
any adjournment of such meeting, but they shall not be valid after final
adjournment of such meeting.  A proxy with respect to stock held in the name of
two or more persons shall be valid if executed by or on behalf of any one of
them unless at or prior to the exercise of the proxy the Corporation receives a
specific written notice to the contrary from any one of them. A proxy purporting
to be executed by or on behalf of a stockholder shall be deemed valid, and the
burden of proving invalidity shall rest on the challenger.

     SECTION 8.  Action at Meeting.  When a quorum is present, any matter before
                 -----------------
any meeting of stockholders shall be decided by the affirmative vote of the
majority of shares present in person or represented by proxy at such meeting and
entitled to vote on such matter, except where a larger vote is required by law,
by the Certificate or by these By-laws.  Any election by stockholders shall be
determined by a plurality of the votes (of the shares present in person or
represented by proxy at the meeting and entitled to vote on the election of
directors), except where a larger vote is required by law, by the Certificate or
by these By-laws.  The Corporation shall not directly or indirectly vote any
shares of its own stock; provided, however, that the Corporation may vote shares
which it holds in a fiduciary capacity to the extent permitted by law.

     SECTION 9.  Stockholder Lists.  The Secretary or an Assistant Secretary (or
                 -----------------
the Corporation's transfer agent or other person authorized by these By-laws or
by law) shall prepare and make, at least 10 days before every Annual Meeting or
special 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 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 hour, date and place of
the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

     SECTION 10.  Presiding Officer.  The Chairman of the Board, if one is
                  -----------------
elected, or if not elected or in his or her absence, the President, shall
preside at all Annual Meetings or

                                       6


special meetings of stockholders and shall have the power, among other things,
to adjourn such meeting at any time and from time to time, subject to Sections 5
and 6 of this Article I. The order of business and all other matters of
procedure at any meeting of the stockholders shall be determined by the
presiding officer.

     SECTION 11.  Voting Procedures and Inspectors of Elections.  The
                  ---------------------------------------------
Corporation 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 no inspector or alternate is able to act at
a meeting of stockholders, the presiding officer shall appoint one or more
inspectors to act at the meeting.  Any inspector may, but need not, be an
officer, employee or agent of the Corporation.  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 perform such duties as are
required by the General Corporation Law of the State of Delaware, as amended
from time to time (the "DGCL"), including the counting of all votes and ballots.
The inspectors may appoint or retain other persons or entities to assist the
inspectors in the performance of the duties of the inspectors.  The presiding
officer may review all determinations made by the inspectors, and in so doing
the presiding officer shall be entitled to exercise his or her sole judgment and
discretion and he or she shall not be bound by any determinations made by the
inspectors.  All determinations by the inspectors and, if applicable, the
presiding officer, shall be subject to further review by any court of competent
jurisdiction.


                                  ARTICLE II
                                  ----------

                                   Directors
                                   ---------

     SECTION 1.  Powers.  The business and affairs of the Corporation shall be
                 ------
managed by or under the direction of the Board of Directors except as otherwise
provided by the Certificate or required by law.

     SECTION 2.  Number and Terms.  The number of directors of the Corporation
                 ----------------
shall be fixed by resolution duly adopted from time to time by the Board of
Directors.  The directors shall hold office in the manner provided in the
Certificate.

     SECTION 3.  Qualification.  No director need be a stockholder of the
                 -------------
Corporation.

     SECTION 4.  Vacancies.  Subject to the rights, if any, of the holders of
                 ---------
any series of preferred stock to elect directors and to fill vacancies in the
Board of Directors relating thereto, any and all vacancies in the Board of
Directors, however occurring, including, without limitation, by reason of an
increase in size of the Board of Directors, or the death, resignation,
disqualification or removal of a director, shall be filled solely by the
affirmative vote of a

                                       7


majority of the remaining directors then in office, even if less than a quorum
of the Board of Directors. Any director appointed in accordance with the
preceding sentence shall hold office for the remainder of the full term of the
class of directors in which the new directorship was created or the vacancy
occurred and until such director's successor shall have been duly elected and
qualified or until his or her earlier resignation or removal. Subject to the
rights, if any, of the holders of any series of preferred stock to elect
directors, when the number of directors is increased or decreased, the Board of
Directors shall determine the class or classes to which the increased or
decreased number of directors shall be apportioned; provided, however, that no
decrease in the number of directors shall shorten the term of any incumbent
director. 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 5.  Removal.  Directors may be removed from office in the manner
                 -------
provided in the Certificate.

     SECTION 6.  Resignation.  A director may resign at any time by giving
                 -----------
written notice to the Chairman of the Board, if one is elected, the President or
the Secretary.  A resignation shall be effective upon receipt, unless the
resignation otherwise provides.

     SECTION 7.  Regular Meetings.  The regular annual meeting of the Board of
                 ----------------
Directors shall be held, without notice other than this Section 7, on the same
date and at the same place as the Annual Meeting following the close of such
meeting of stockholders.  Other regular meetings of the Board of Directors may
be held at such hour, date and place as the Board of Directors may by resolution
from time to time determine without notice other than such resolution.

     SECTION 8.  Special Meetings.  Special meetings of the Board of Directors
                 ----------------
may be called, orally or in writing, by or at the request of a majority of the
directors, the Chairman of the Board, if one is elected, or the President.  The
person calling any such special meeting of the Board of Directors may fix the
hour, date and place thereof.

     SECTION 9.  Notice of Meetings.  Notice of the hour, date and place of all
                 ------------------
special meetings of the Board of Directors shall be given to each director by
the Secretary or an Assistant Secretary, or in case of the death, absence,
incapacity or refusal of such persons, by the Chairman of the Board, if one is
elected, or the President or such other officer designated by the Chairman of
the Board, if one is elected, or the President.  Notice of any special meeting
of the Board of Directors shall be given to each director in person, by
telephone, or by facsimile, telex, telecopy, telegram, or other written form of
electronic communication, sent to his or her business or home address, at least
24 hours in advance of the meeting, or by written notice mailed to his or her
business or home address, at least 48 hours in advance of the meeting.  Such
notice shall be deemed to be delivered when hand delivered to such address, read
to such director by telephone, deposited in the mail so addressed, with postage
thereon

                                       8


prepaid if mailed, dispatched or transmitted if faxed, telexed or telecopied, or
when delivered to the telegraph company if sent by telegram.

     When any Board of Directors meeting, either regular or special, is
adjourned for 30 days or more, notice of the adjourned meeting shall be given as
in the case of an original meeting.  It shall not be necessary to give any
notice of the hour, date or place of any meeting adjourned for less than 30 days
or of the business to be transacted thereat, other than an announcement at the
meeting at which such adjournment is taken of the hour, date and place to which
the meeting is adjourned.

     A written waiver of notice signed before or after a meeting by a director
and filed with the records of the meeting shall be deemed to be equivalent to
notice of the meeting.  The attendance of a director at a meeting shall
constitute a waiver of notice of such meeting, except where a director attends a
meeting for the express purpose of objecting at the beginning of the meeting to
the transaction of any business because such meeting is not lawfully called or
convened.  Except as otherwise required by law, by the Certificate or by these
By-laws, neither the business to be transacted at, nor the purpose of, any
meeting of the Board of Directors need be specified in the notice or waiver of
notice of such meeting.

     SECTION 10.  Quorum.  At any meeting of the Board of Directors, a majority
                  ------
of the directors then in office shall constitute a quorum for the transaction of
business, but if less than a quorum is present at a meeting, a majority of the
directors present may adjourn the meeting from time to time, and the meeting may
be held as adjourned without further notice, except as provided in Section 9 of
this Article II.  Any business which might have been transacted at the meeting
as originally noticed may be transacted at such adjourned meeting at which a
quorum is present.

     SECTION 11.  Action at Meeting.  At any meeting of the Board of Directors
                  -----------------
at which a quorum is present, a majority of the directors present may take any
action on behalf of the Board of Directors, unless otherwise required by law, by
the Certificate or by these By-laws.

     SECTION 12.  Action by Consent.  Any action required or permitted to be
                  -----------------
taken at any meeting of the Board of Directors may be taken without a meeting if
all members of the Board of Directors consent thereto in writing.  Such written
consent shall be filed with the records of the meetings of the Board of
Directors and shall be treated for all purposes as a vote at a meeting of the

requesting such advance or advances from time to time, whether prior to or after
final disposition of such Proceeding.  Such statement or statements shall
reasonably evidence the Expenses incurred by such Director and shall be preceded
or accompanied by an undertaking by or on behalf of such Director to repay any
Expenses so advanced if it shall ultimately be determined that such Director is
not entitled to be indemnified against such Expenses.

Prior to Final Disposition.

          -----------------------
Board of Directors of the Corporation, advance any or all Expenses incurred by
or on behalf of any Officer in connection with any Proceeding in which such is
involved by reason of such Officer's Corporate Status upon the receipt by the
Corporation of a statement or statements from such Officer requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding.  Such statement or statements shall reasonably
evidence the Expenses incurred by such Officer and shall be preceded or
accompanied by an undertaking by or on behalf of such to repay any Expenses so
advanced if it shall ultimately be determined that such Officer is not entitled
to be indemnified against such Expenses.

     (b)  Advancement to Non-Officer Employees. The Corporation may, at the
          ------------------------------------
discretion of the Board of Directors or of any Officer who is authorized to act
on behalf of the Corporation, advance any or all Expenses incurred by or on

Corporate Status upon the receipt by the Corporation of a statement or
statements from such Non-Officer Employee requesting such advance or advances
from time to time, whether prior to or after final disposition of such
Proceeding.  Such statement or statements shall reasonably evidence the Expenses
incurred by such Non-Officer Employee and shall be preceded or accompanied by an
undertaking by or on behalf of such Non-Officer Employee to repay any Expenses
so advanced if it shall ultimately be determined that such Non-Officer Employee
is not entitled to be indemnified against such Expenses.

Article V is in effect, and any repeal or modification thereof shall not affect
any rights or obligations then existing with respect to any state of facts then
or theretofore existing or any Proceeding theretofore or thereafter brought
based in whole or in part upon any such state of facts.  If a claim for
indemnification or advancement of Expenses hereunder by a Director or Officer is
not paid in full by the Corporation within (a) 60 days after receipt by the
Corporation's of a written claim for indemnification, or (b) in the case of a
Director, 10 days after receipt by the Corporation of documentation of Expenses
and the required undertaking, such Director or Officer may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim, and if successful in whole or in part, such Director or Officer shall
also be entitled to be paid the expenses of prosecuting such claim.  The failure
of the Corporation (including its Board of Directors or any committee thereof,
independent legal counsel, or stockholders) to make a determination concerning
the permissibility of such indemnification or, in the case of a Director,
advancement of Expenses, under this Article V shall not be a defense to the
action and shall not create a presumption that such indemnification or
advancement is not permissible.

     SECTION 8.  Non-Exclusivity of Rights.  The rights to indemnification and
                 -------------------------
advancement of Expenses set forth in this Article V shall not be exclusive of
any other right

                                       17


which any Director, Officer, or Non-Officer Employee may have or hereafter
acquire under any statute, provision of the Certificate or these By-laws,
agreement, vote of stockholders or Disinterested Directors or otherwise.

                 ---------
expense, to protect itself and any Director, Officer or Non-Officer Employee
against any liability of any character asserted against or incurred by the
Corporation or any such Director, Officer or Non-Officer Employee, or arising
out of any such person's Corporate Status, whether or not the Corporation would
have the power to indemnify such person against such liability under the DGCL or
the provisions of this Article V.
