                           (a Delaware corporation)

                               CORPORATE OFFICES
                               -----------------


     1.1  REGISTERED OFFICE
          -----------------

     The registered office of the corporation shall be fixed in the certificate
of incorporation of the corporation.

     1.2  OTHER OFFICES
          -------------

     The board of directors may at any time establish branch or subordinate
offices at any place or places where the corporation is qualified to do
business.

                            MEETINGS OF STOCKHOLDERS
                            ------------------------


     2.1  PLACE OF MEETINGS
          -----------------

     Meetings of stockholders shall be held at any place within or outside the
State of Delaware designated by the board of directors.  In the absence of any
such designation, stockholders' meetings shall be held at the principal
executive office of the corporation.

     2.2  ANNUAL MEETING
          --------------

     The annual meeting of the stockholders of this corporation shall be held
each year on a date and at a time designated by the board of directors.  At the
meeting, directors shall be elected and any other proper business may be
transacted.  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 of stockholders only (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
<PAGE>

was a stockholder of record at the time of giving of notice provided for in
these Bylaws, who is entitled to vote at the meeting and who complies with the
notice procedures set forth in this Bylaw.

     For nominations or other business to be properly brought before an annual
meeting by a stockholder pursuant to clause (c) of the preceding sentence, 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 shall be delivered to
the secretary at the principal executive offices of the corporation not later
than the close of business on the 60th day, but not earlier than the close of
business on the 90th day, prior to the meeting; provided, however, that in the
event that less than 65 days notice of the meeting is given to stockholders,
notice by the stockholder to be timely must be so delivered not earlier than the
close of business on the seventh (7th) day following the day on which the notice
of meeting was mailed.  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
(or any successor thereto) (the "Exchange Act") and Rule 14a-11 thereunder (or
any successor thereto) (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 of record by such stockholder and such beneficial owner. Notwithstanding any
provision herein to the contrary, no business shall be conducted at an annual
meeting except in accordance with the procedures set forth in this Section 2.2.

     2.3  SPECIAL MEETING
          ---------------

     A special meeting of the stockholders may be called at any time by the
board of directors, or by the chairman of the board or by the president.

     If a special meeting is called by any person or persons other than the
board of directors, the request shall be in writing to the secretary of the
corporation, and shall set forth (a) as to each person whom such person or
persons propose to nominate for election or reelection as a director at such
meeting all information relating to such proposed nominee 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 Exchange Act (or any successor thereto) and Rule 14a-11 thereunder (or any
successor thereto) (including such proposed nominee's written consent to being
named in the proxy statement as a nominee and to serving as a director if
elected);

                                      -2-
<PAGE>

(b) as to any other business to be taken at the meeting, a brief description of
such business, the reasons for conducting such business and any material
interest in such business of the person or persons calling such meeting and the
beneficial owners, if any, on whose behalf such meeting is called; and (c) as to
the person or persons calling such meeting and the beneficial owners, if any, on
whose behalf the meeting is called (i) the name and address of such persons, as
they appear on the corporation's books, and of such beneficial owners, and (ii)
the class and number of shares of the corporation that are owned beneficially
and of record by such persons and such beneficial owners. No business may be
transacted at such special meeting otherwise than specified in such notice or by
or at the direction of the corporation's board of directors. The corporation's
secretary shall cause notice to be promptly given to the stockholders entitled
to vote, in accordance with the provisions of Sections 2.4 and 2.5, that a
meeting will be held at the time reasonably requested by the person or persons
who called the meeting, not less than 60 nor more than 90 days after the receipt
of the request. If the notice is not given within 20 days after the receipt of a
valid request, the person or persons requesting the meeting may give the notice.
Nothing contained in this paragraph 2.3 shall be construed as limiting, fixing
or affecting the time when a meeting of stockholders called by action of the
board of directors may be held.

     Only such business shall be conducted at a special meeting of stockholders
called by action of the board of directors as shall have been brought before the
meeting pursuant to the corporation's notice of meeting.

     2.4  NOTICE OF STOCKHOLDERS' MEETINGS
          --------------------------------

     All notices of meetings of stockholders shall be sent or otherwise given in
accordance with Sections 2.2 and 2.3 of these bylaws not less than ten (10) nor
more than sixty (60) days before the date of the meeting.  The notice shall
specify the place, date and hour of the meeting and (i) in the case of a special
meeting, the purpose or purposes for which the meeting is called (no business
other than that specified in the notice may be transacted) or (ii) in the case
of the annual meeting, those matters which the board of directors, at the time
of giving the notice, intends to present for action by the stockholders (but any
proper matter may be presented at the meeting for such action).  The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

     2.5  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE
          --------------------------------------------

     Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication.  Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice.  Notice shall be deemed to have been
given at the time when delivered personally or deposited in the mail or sent by
telegram or other means of written communication.

                                      -3-
<PAGE>

     An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

     2.6  QUORUM
          ------

     The holders of a majority in voting power 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 pro vided by statute or by the
certificate of incorporation. If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (i) the chairman of
the meeting or (ii) the stockholders entitled to vote thereat, present in person
or represented by proxy, shall have power to adjourn the meeting in accordance
with Section 2.7 of these bylaws.

     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 the laws of the State of Delaware or
of the certificate of incorporation or these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of the question.

     If a quorum be initially present, the stockholders may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

     2.7  ADJOURNED MEETING; NOTICE
          -------------------------

     When a meeting is adjourned to another time and place, unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken.  At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting.  If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

     2.8  VOTING
          ------

     The stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.10 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint
owners, and to voting trusts and other voting agreements).

     Except as may be otherwise provided in the certificate of incorporation or
these bylaws, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

                                      -4-
<PAGE>

     2.9  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING
          -------------------------------------------------------

     The stockholders may not take any action by written consent in lieu of a
meeting, and must take any actions at a duly called annual or special meeting of
stockholders and the power of stockholders to consent in writing is specifically
denied.

     2.10 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING
          ------------------------------------------

     For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors and which shall not be more
than sixty (60) days nor less than ten (10) days before the date of any such
meeting, and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date.

     If the board of directors does not so fix a record date, 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 business day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the business day next preceding the day on which the
meeting is held.

     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
unless the board of directors fixes a new record date for the adjourned meeting,
but the board of directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original
meeting.

     The record date for any other purpose shall be as provided in Section 8.1
of these bylaws.

     2.11 PROXIES
          -------

     Every person entitled to vote for directors, or on any other matter, shall
have the right to do so either in person or by one or more agents authorized by
a written proxy signed by the person and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period.  A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission, telefacsimile or
otherwise) by the stockholder or the stockholder's attorney-in-fact.  The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
Delaware.

     2.12 ORGANIZATION
          ------------

     The president, or in the absence of the president, the chairman of the
board, shall call the meeting of the stockholders to order, and shall act as
chairman of the meeting.  In the absence of the president, the chairman of the
board, and all of the vice presidents, the stockholders shall appoint a chairman
for such meeting.  The chairman of any meeting of stockholders shall determine
the order

                                      -5-
<PAGE>

of business and the procedures at the meeting, including such matters as the
regulation of the manner of voting and the conduct of business. The secretary of
the corporation shall act as secretary of all meetings of the stockholders, but
in the absence of the secretary at any meeting of the stockholders, the chairman
of the meeting may appoint any person to act as secretary of the meeting.

     2.13 LIST OF STOCKHOLDERS ENTITLED TO VOTE
          -------------------------------------

     The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  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 (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

                                   DIRECTORS
                                   ---------


     3.1  POWERS
          ------

     Subject to the provisions of the General Corporation Law of Delaware and to
any limitations in the certificate of incorporation or these bylaws relating to
action required to be approved by the stockholders or by the outstanding shares,
the business and affairs of the corporation shall be managed and all corporate
powers shall be exercised by or under the direction of the board of directors.

     3.2  NUMBER OF DIRECTORS
          -------------------

board of directors or by the stockholders, or by a duly adopted amendment to the
certificate of incorporation.

                                      -6-
<PAGE>

     3.3  ELECTION AND TERM OF OFFICE OF DIRECTORS
          ----------------------------------------

     Except as provided in Section 3.4 of these bylaws or the certificate of
incorporation, directors shall be elected at each annual meeting of stockholders
to hold office until the next annual meeting. Each director, including a
director elected or appointed to fill a vacancy, shall hold office until the
expiration of the term for which elected and until a successor has been elected
and qualified.

     Election of directors need not be by written ballot.

     3.4  RESIGNATION AND VACANCIES
          -------------------------

     Any director may resign effective on giving written notice to the chairman
of the board, the president, the secretary or the board of directors, unless the
notice specifies a later time for that resignation to become effective.  If the
resignation of a director is effective at a future time, the board of directors
may elect a successor to take office when the resignation becomes effective.

     Unless otherwise provided in the certificate of incorporation or these
bylaws:

          (i)  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director; provided however, a vacancy created by the removal of a
director by the vote of the stockholders or by court order may be filled only by
the affirmative vote of a majority of the shares represented and voting at a
duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute a majority of the required quorum).  Unless
otherwise provided in the certificate of incorporation or these bylaws, each
director so elected shall hold office until the next annual meeting of the
stockholders and until a successor has been elected and qualified..

          (ii) Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

     If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

     If, at the time of filling any vacancy or any newly created directorship,
the directors then in office constitute less than a majority of the whole board
(as constituted immediately prior to any such

                                      -7-

increase), then the Court of Chancery may, upon application of any stockholder
or stockholders holding at least ten percent (10%) of the total number of the
shares then outstanding having the right to vote for such directors, summarily
order an election to be held to fill any such vacancies or newly created
directorships, or to replace the directors chosen by the directors then in
office as aforesaid, which election shall be governed by the provisions of
Section 211 of the General Corporation Law of Delaware as far as applicable.

of directors as provided in Section 151(a) of the General Corporation Law of
Delaware, fix the designations and any of the preferences or rights of such
shares relating to dividends, redemption, dissolution, any distribution of
assets of the corporation or the conversion into, or the exchange of such shares

other class or classes of stock of the corporation), (ii) adopt an agreement of
merger or consolidation under Sections 251 or 252 of the General Corporation Law
of Delaware, (iii) recommend to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets, (iv)
recommend to the stockholders a dissolution of the corporation or a revocation
of a dissolution or (v) amend the bylaws of the corporation; and, unless the
board resolution establishing the committee, the bylaws or the certificate of

     The corporation shall, to the maximum extent and in the manner permitted by
the General Corporation Law of Delaware as the same now exists or may hereafter
be amended, indemnify any person against expenses (including attorneys' fees),
judgments, fines, and amounts paid in settlement actually and reasonably
incurred in connection with any threatened, pending or completed action, suit,
or proceeding in which such person was or is a party or is threatened to be made
a party by reason of the fact that such person is or was a director or officer
of the corporation.  For purposes of this Section 6.1, a "director" or "officer"
of the corporation shall mean any person (i) who is or was a director or officer
of the corporation, (ii) who is or was serving at the request of the corporation
as a director or officer of another corporation, partnership, joint venture,
trust or other enterprise, or (iii) who was a director or officer of a
corporation which was a predecessor corporation of the corporation or of another
enterprise at the request of such predecessor corporation.

     The corporation shall be required to indemnify a director or officer in
connection with an action, suit, or proceeding (or part thereof) initiated by
such director or officer only if the initiation of such action, suit, or
proceeding (or part thereof) by the director or officer was authorized by the
board of directors of the corporation.

     The corporation shall pay the expenses (including attorney's fees) incurred
by a director or officer of the corporation entitled to indemnification
hereunder in defending any action, suit or proceeding referred to in this
Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer to repay all amounts
advanced if it should ultimately be determined that the director or officer is
not entitled to be indemnified under this Section 6.1 or otherwise.

     If a claim for indemnification or payment of expenses under this Article is
not paid in full within sixty days after a written claim therefor has been
received by the corporation the claimant may file suit to recover the unpaid
amount of such claim and, if successful in whole or in part, shall be entitled
to be paid the expense of prosecuting such claim.  In any such action the
corporation shall have the burden of proving that the claimant was not entitled
to the requested indemnification or payment of expenses under applicable law.

     The rights conferred on any person by this Article shall not be exclusive
of any other rights which such person may have or hereafter acquire under any
statute, provision of the corporation's Certificate of Incorporation, these
bylaws, agreement, vote of the stockholders or disinterested directors or
otherwise.

                                      -14-

modification.

     6.2  INDEMNIFICATION OF OTHERS
          -------------------------

     The corporation shall have the power, to the maximum extent and in the
manner permitted by the General Corporation Law of Delaware as the same now
exists or may hereafter be amended, to indemnify any person (other than
directors and officers) against expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred in
connection with any threatened, pending or completed action, suit, or
proceeding, in which such person was or is a party or is threatened to be made a
party by reason of the fact that such person is or was an employee or agent of
the corporation.  The corporation's obligation, if any, to indemnify any person
who was or is serving at its request as a director, officer, employee or agent
of another corporation, partnership, joint venture, trust, enterprise or non-
profit entity shall be reduced by any amount such person may collect as
indemnification from such other corporation, partnership, joint venture, trust,
enterprise or non-profit enterprise.  For purposes of this Section 6.2, an
"employee" or "agent" of the corporation (other than a director or officer)
shall mean any person (i) who is or was an employee or agent of the corporation,
(ii) who is or was serving at the request of the corporation as an employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, or (iii) who was an employee or agent of a corporation which was a
predecessor corporation of the corporation or of another enterprise at the
request of such predecessor corporation.

     6.3  INSURANCE
          ---------

     The corporation may 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 him or her 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 him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

shares on the books of the corpo  ration after the record date so fixed, except

any contract or execute any instrument in the name of and on behalf of the
corporation; such power and authority may be general or confined to specific
instances.  Unless so authorized or ratified by the board of directors or within
the agency power of an officer, no officer, agent or employee shall have any
power or authority to bind the corporation by any contract or engagement or to
pledge its credit or to render it liable for any purpose or for any amount.

     8.4  STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES
          ------------------------------------------------

     The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the corporation.

                                      -17-
<PAGE>

Notwithstanding the adoption of such a resolution by the board of directors,
every holder of stock represented by certificates and, upon request, every
holder of uncertificated shares, shall be entitled to have a certificate signed
by, or in the name of the corporation by, the chairman or vice-chairman of the
board of directors, or the president or vice-president, and by the treasurer or
an assistant treasurer, or the secretary or an assistant secretary of such
corporation representing the number of shares registered in certificate form.
Any or all of the signatures on the certificate may be a facsimile. In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate has ceased to be such officer, transfer agent
or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he or she were such officer, transfer
agent or registrar at the date of issue.

     Certificates for shares shall be of such form and device as the board of
directors may designate and shall state the name of the record holder of the
shares represented thereby; its number; date of issuance; the number of shares
for which it is issued; a summary statement or reference to the powers,
designations, preferences or other special rights of such stock and the
qualifications, limitations or restrictions of such preferences and/or rights,
if any; a statement or summary of liens, if any; a conspicuous notice of
restrictions upon transfer or registration of transfer, if any; a statement as
to any applicable voting trust agreement; if the shares be assessable, or, if
assessments are collectible by personal action, a plain statement of such facts.

     Upon surrender to the secretary or transfer agent of the corporation of a
certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books.

     The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor.  Upon the face or back of each stock certificate issued to represent
any such partly paid shares, or upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

     8.5  SPECIAL DESIGNATION ON CERTIFICATES
          -----------------------------------

     If the corporation is authorized to issue more than one class of stock or
more than one series of any class, then the powers, the designations, the
preferences and the relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the

                                      -18-
<PAGE>

powers, the designations, the preferences and the relative, participating,
optional or other special rights of each class of stock or series thereof and
the qualifications, limitations or restrictions of such preferences and/or
rights.

     8.6  LOST CERTIFICATES
          -----------------

     Except as provided in this Section 8.6, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time.  The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

     8.7  TRANSFER AGENTS AND REGISTRARS
          ------------------------------

     The board of directors may appoint one or more transfer agents or transfer
clerks, and one or more registrars, each of which shall be an incorporated bank
or trust company--either domestic or foreign--who shall be appointed at such
times and places as the requirements of the corporation may necessitate and the
board of directors may designate.

     8.8  CONSTRUCTION; DEFINITIONS
          -------------------------

     Unless the context requires otherwise, the general provisions, rules of
construction and definitions in the General Corporation Law of Delaware shall
govern the construction of these bylaws.  Without limiting the generality of
this provision, as used in these bylaws, the singular number includes the
plural, the plural number includes the singular, and the term "person" includes
both an entity and a natural person.


                                   ARTICLE IX

                                   AMENDMENTS
                                   ----------


     Any of these bylaws may be altered, amended or repealed by the affirmative
vote of a majority of the members of the board of directors or, with respect to
bylaw amendments, excluding amendments relating to Sections 2.2, 2.3, 2.9 or
Article VI, placed before the stockholders for approval and except as otherwise
provided herein or required by law, by the affirmative vote of the holders of a
majority of the shares of the corporation's stock entitled to vote, voting as
one class, and with respect to bylaw amendments relating to Sections 2.2, 2.3,
2.9 or Article VI, placed before the stockholders for approval and except as
otherwise provided herein or required by law, by the

                                      -19-
<PAGE>

affirmative vote of the holders of at least two-thirds of the shares of the
corporation's stock entitled to vote, voting as one class.

     Whenever an amendment or new bylaw is adopted, it shall be copied in the
book of bylaws with the original bylaws, in the appropriate place.  If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.
