    Subject  to the rights of  holders of any class or  series of stock having a
preference over the Common Stock as to dividends or upon liquidation,
 
         (i) nominations for the election of directors, and
 
        (ii) business proposed to be brought before any stockholder meeting
 
may be made by the board of directors or proxy committee appointed by the  board
of directors or by any stockholder entitled to vote in the election of directors
generally  if such nomination or business  proposed is otherwise proper business
before such meeting.  However, any  such stockholder  may nominate  one or  more
persons for election as directors at a meeting or propose business to be brought
before  a meeting, or both, but only if such stockholder has given timely notice
in proper written form of such  stockholder's intent to make such nomination  or
nominations or to propose such business. To be timely, such stockholder's notice
must  be delivered to or mailed and  received at the principal executive offices
of the  corporation not  less than  one hundred  twenty (120)  calendar days  in
advance  of the date specified in  the corporation's proxy statement released to
stockholders  in  connection  with  the   previous  year's  annual  meeting   of
stockholders;  provided, however, that  in the event that  no annual meeting was
held in the previous year or the date of the annual meeting has been changed  by
more  than  thirty (30)  days  from the  date contemplated  at  the time  of the
previous year's proxy statement, notice by the stockholder to be timely must  be
so  received a reasonable time before the  solicitation is made. To be in proper
form, a stockholder's notice to the secretary shall set forth:
 
        (i) the name  and address  of the stockholder  who intends  to make  the
    nominations  or propose the business and, as  the case may be, of the person
    or persons to be nominated or of the business to be proposed;
 
        (ii) a representation  that the  stockholder is  a holder  of record  of
    stock  of  the  corporation  entitled  to  vote  at  such  meeting  and,  if
    applicable, intends  to appear  in person  or  by proxy  at the  meeting  to
    nominate the person or persons specified in the notice;
 
       (iii)  if applicable, a description of all arrangements or understandings
    between the stockholder  and each nominee  and any other  person or  persons
    (naming  such  person  or  persons)  pursuant  to  which  the  nomination or
    nominations are to be made by the stockholder;
 
       (iv) such  other information  regarding each  nominee or  each matter  of
    business  to be  proposed by  such stockholder  as would  be required  to be
    included in  a proxy  statement filed  pursuant to  the proxy  rules of  the
    Securities  and  Exchange  Commission  had the  nominee  been  nominated, or
    intended to be  nominated, or the  matter been proposed,  or intended to  be
    proposed by the board of directors; and
 
        (v)  if applicable, the consent of each  nominee to serve as director of
    the corporation if so elected.
 
    The chairman of the  meeting shall refuse to  acknowledge the nomination  of
any  person or  the proposal  of any  business not  made in  compliance with the
foregoing procedure.
 
    II.6  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE
 
    Written notice of  any meeting  of stockholders,  if mailed,  is given  when
deposited   in  the  United  States  mail,  postage  prepaid,  directed  to  the
stockholder   at   his   address   as    it   appears   on   the   records    of
 
                                      A-2

the  corporation. An affidavit of the secretary  or an assistant secretary or of
the transfer agent of the corporation that  the notice has been given shall,  in
the absence of fraud, be prima facie evidence of the facts stated therein.
 
    II.7  QUORUM
 
    The  holders of a majority of the  stock issued and outstanding and entitled
to vote thereat, present in person  or represented by proxy, shall constitute  a
quorum  at  all meetings  of the  stockholders for  the transaction  of business
except as otherwise provided by statute or by the certificate of  incorporation.
If,  however, such quorum  is not present  or represented at  any meeting of the
stockholders, then the stockholders entitled to vote thereat, present in  person
or  represented by proxy, shall  have power to adjourn  the meeting from time to
time, without notice other than announcement  at the meeting, until a quorum  is
present  or represented. At such adjourned meeting  at which a quorum is present
or represented, any business may be  transacted that might have been  transacted
at the meeting as originally noticed.
 
    II.8  ADJOURNED MEETING; NOTICE
 
    When  a meeting is adjourned  to another time or  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.
 
    II.9  VOTING
 
    The  stockholders entitled to  vote at any meeting  of stockholders shall be
determined in accordance with  the provisions of Section  2.11 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
of stock and to voting trusts and other voting agreements).
 
    Except  as may otherwise be 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 and stockholders shall not be entitled to
cumulate  their votes in the election of directors or with respect to any matter
submitted to a vote of stockholders.
 
    II.10  WAIVER OF NOTICE
 
    Whenever notice is required to be  given under any provision of the  General
Corporation  Law of  Delaware or  of the  certificate of  incorporation or these
bylaws, a  written waiver  thereof, signed  by the  person entitled  to  notice,
whether  before or after the time stated  therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of  notice
of  such  meeting, except  when the  person  attends a  meeting for  the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the  meeting is not  lawfully called or  convened. Neither  the
business to be transacted at, nor the purpose of, any regular or special meeting
of  the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.
 
    II.11  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING
 
    Unless otherwise provided  in the certificate  of incorporation, any  action
required  by  this chapter  to  be taken  at any  annual  or special  meeting of
stockholders of a corporation, or any action that may be taken at any annual  or
special  meeting of such  stockholders, may be taken  without a meeting, without
prior notice, and  without a vote  if a  consent in writing,  setting forth  the
action so taken, is signed by
 
                                      A-3

the  holders of  outstanding stock  having not less  than the  minimum number of
votes that would be necessary to authorize  or take such action at a meeting  at
which all shares entitled to vote thereon were present and voted.
 
    Prompt  notice of the  taking of the  corporate action without  a meeting by
less than unanimous  written consent shall  be given to  those stockholders  who
have  not consented in writing.  If the action which is  consented to is such as
would have required the filing of a certificate under any section of the General
Corporation Law of Delaware if such action had been voted on by stockholders  at
a meeting thereof, then the certificate filed under such section shall state, in
lieu  of  any  statement  required  by  such  section  concerning  any  vote  of
stockholders, that  written  notice  and  written consent  have  been  given  as
provided in Section 228 of the General Corporation Law of Delaware.
 
    II.12  RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS
 
    In  order that  the corporation may  determine the  stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment  thereof,
or entitled to express consent to corporate action in writing without a meeting,
or  entitled  to  receive  payment  of any  dividend  or  other  distribution or
allotment of any rights, or  entitled to exercise any  rights in respect of  any
change,  conversion or exchange of stock or  for the purpose of any other lawful
action, the board of directors may fix,  in advance, a record date, which  shall
not  be more than sixty (60) nor less than ten (10) days before the date of such
meeting, nor more than sixty (60) days prior to any other action.
 
    If the board of directors does not so fix a record date:
 
        (i) The record date for  determining stockholders entitled to notice  of
    or to vote at a meeting of stockholders shall be at the close of business on
    the  day next preceding the  day on which notice is  given, or, if notice is
    waived, at the close of business on the day next preceding the day on  which
    the meeting is held.
 
        (ii)  The record date  for determining stockholders  entitled to express
    consent to corporate  action in  writing without  a meeting,  when no  prior
    action by the board of directors is necessary, shall be the day on which the
    first written consent is expressed.
 
       (iii)  The record date for determining stockholders for any other purpose
    shall be at the close of business on the day on which the board of directors
    adopts the resolution relating thereto.
 
    A determination of stockholders of record  entitled to notice of or to  vote
at  a meeting  of stockholders  shall apply to  any adjournment  of the meeting;
provided, however, that the board of directors may fix a new record date for the
adjourned meeting.
 
    II.13  PROXIES
 
    Each stockholder entitled to vote at a meeting of stockholders or to express
consent or  dissent  to  corporate  action in  writing  without  a  meeting  may
authorize another person or persons to act for him by a written proxy, signed by
the  stockholder 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 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(c) of the General Corporation Law of Delaware.
 
    II.14  LIST OF STOCKHOLDERS ENTITLED TO VOTE
 
    The officer  who has  charge of  the  stock ledger  of a  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
 
                                      A-4

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

the  meeting  during  the  whole  time thereof,  and  may  be  inspected  by any
stockholder who is present.

directors  may be  changed by an  amendment to  this bylaw, duly  adopted by the
board of directors or by the stockholders, or by a duly adopted amendment to the
certificate of incorporation. No reduction of the authorized number of directors
shall have the effect  of removing any director  before that director's term  of
office expires.
 
    III.3  ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS
 
    Except  as  provided in  Section  3.4 of  these  bylaws, directors  shall be
elected at each  annual meeting of  stockholders to hold  office until the  next
annual  meeting. Directors  need not be  stockholders unless so  required by the
certificate of incorporation or these  bylaws, wherein other qualifications  for
directors may be prescribed. Each director, including a director elected to fill
a  vacancy, shall hold  office until his  successor is elected  and qualified or
until his earlier resignation or removal. Elections of directors need not be  by
written ballot.
 
    III.4  RESIGNATION AND VACANCIES
 
    Any  director may resign at any time upon written notice to the corporation.

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.
 
        (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
 
                                      A-5

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 increase),  then the  Court  of
Chancery  may, upon  application of any  stockholder or  stockholders holding at
least ten (10) percent of the total number of the shares at the time 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.
 
    III.5  PLACE OF MEETINGS; MEETINGS BY TELEPHONE
 
    The board of directors  of the corporation may  hold meetings, both  regular
and special, either within or outside the State of Delaware.

board  of directors, may participate in a  meeting of the board of directors, or
any committee,  by  means  of conference  telephone  or  similar  communications
equipment  by means of which  all persons participating in  the meeting can hear

such time and  place as  shall be  specified in  a notice  given as  hereinafter

is to be held at the principal executive office of the corporation.
 
    III.9  QUORUM
 
    At  all meetings  of the  board of directors,  a majority  of the authorized
number of directors shall  constitute a quorum for  the transaction of  business
and the act of a majority of the directors present at any meeting at which there
is  a  quorum shall  be the  act of  the board  of directors,  except as  may be
otherwise  specifically  provided   by  statute   or  by   the  certificate   of
incorporation. If a quorum is not
 
                                      A-6

present  at any meeting  of the board  of directors, then  the directors present
thereat may adjourn  the meeting from  time to time,  without notice other  than
announcement at the meeting, until a quorum is present.
 
    III.10  WAIVER OF NOTICE
 
    Whenever  notice is required to be given  under any provision of the General
Corporation Law of  Delaware or  of the  certificate of  incorporation or  these
bylaws,  a  written waiver  thereof, signed  by the  person entitled  to notice,
whether before or after the time  stated therein, shall be deemed equivalent  to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such  meeting, except  when the  person  attends a  meeting for  the  express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business  because the  meeting is not  lawfully called or  convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the directors, or members of a  committee of directors, need be specified  in
any  written  waiver  of  notice  unless  so  required  by  the  certificate  of
incorporation or these bylaws.
 
    III.11  ADJOURNED MEETING; NOTICE

subsidiary,  including  any  officer  or  employee  who  is  a  director  of the
corporation or its subsidiary, whenever, in the judgment of the directors,  such
loan,  guaranty  or  assistance  may  reasonably  be  expected  to  benefit  the
corporation. The  loan, guaranty  or other  assistance may  be with  or  without
interest  and  may be  unsecured,  or secured  in such  manner  as the  board of
directors shall approve, including,  without limitation, a  pledge of shares  of

directors as alternate members of any  committee, who may replace any absent  or
disqualified  member  at  any  meeting  of  the  committee.  In  the  absence or
disqualification of  a member  of a  committee, the  member or  members  thereof
present  at any meeting and  not disqualified from voting,  whether or not he or
they constitute a quorum, may unanimously appoint another member of the board of

exercise  all  the  powers  and  authority of  the  board  of  directors  in the
management of the business and affairs of the corporation, and may authorize the
seal of the corporation to be affixed to all papers that may require it; but  no
such committee shall have the power or authority to (i) amend the certificate of
incorporation  (except that  a committee  may, to  the extent  authorized in the
resolution or resolutions providing for the issuance of shares of stock  adopted
by  the  board  of  directors  as provided  in  Section  151(a)  of  the General
Corporation Law of Delaware, fix 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 for,
shares of any  other class or  classes or any  other series of  the same or  any
other  class or classes of stock of the corporation), (ii) adopt an agreement of

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)

incorporation  expressly so provide,  no such committee shall  have the power or
authority to declare a dividend, to authorize the issuance of stock, or to adopt
a certificate of  ownership and merger  pursuant to Section  253 of the  General
Corporation Law of Delaware.

the General Corporation  Law of Delaware,  indemnify each of  its directors  and
officers   against  expenses  (including  attorneys'  fees),  judgments,  fines,
settlements, and other  amounts actually and  reasonably incurred in  connection
with any proceeding, arising by reason of the fact that such person is or was an
agent  of the  corporation. For  purposes of this  Section 6.1,  a "director" or
"officer" of the corporation includes 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.
 
    VI.2  INDEMNIFICATION OF OTHERS
 
    The  corporation  shall have  the power,  to  the extent  and in  the manner
permitted by the General Corporation Law  of Delaware, to indemnify each of  its
employees  and  agents  (other  than directors  and  officers)  against expenses
(including attorneys' fees),  judgments, fines, settlements,  and other  amounts
actually  and reasonably incurred in connection  with any proceeding, arising by
reason of the fact that such person is  or was an agent of the corporation.  For

employee  or agent of another corporation,  partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by  him
in  any such capacity, or arising out of  his status as such, whether or not the
corporation would have the power to  indemnify him against such liability  under
the provisions of the General Corporation Law of Delaware.

                                  ARTICLE VII
                              RECORDS AND REPORTS
 
    VII.1  MAINTENANCE AND INSPECTION OF RECORDS
 
    The  corporation shall, either at its  principal executive office or at such
place or places as designated  by the board of directors,  keep a record of  its
shareholders  listing  their names  and addresses  and the  number and  class of
shares held by  each shareholder, a  copy of  these bylaws as  amended to  date,
accounting books, and other records.
 
    Any  stockholder of record, in person or  by attorney or other agent, shall,
upon written  demand under  oath stating  the purpose  thereof, have  the  right
during  the  usual hours  for business  to  inspect for  any proper  purpose the
corporation's stock ledger, a list of its stockholders, and its other books  and
records  and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder. In  every
instance  where an attorney or other agent is  the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing  that authorizes the  attorney or  other agent to  so act  on
behalf  of  the stockholder.  The demand  under  oath shall  be directed  to the
corporation at its registered  office in Delaware or  at its principal place  of
business.
 
    The  officer  who has  charge of  the  stock ledger  of a  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.
 
    VII.2  INSPECTION BY DIRECTORS
 
    Any director shall have the right to examine the corporation's stock ledger,
a list  of its  stockholders, and  its other  books and  records for  a  purpose
reasonably  related to  his position  as a  director. The  Court of  Chancery is
hereby vested with the exclusive jurisdiction to determine whether a director is
entitled to the inspection sought. The Court may summarily order the corporation
to permit the  director to  inspect any  and all  books and  records, the  stock
ledger,  and the stock list and to  make copies or extracts therefrom. The Court
may, in its discretion, prescribe  any limitations or conditions with  reference
to  the inspection, or award such other and further relief as the Court may deem
just and proper.
 
    VII.3  REPRESENTATION OF SHARES OF OTHER CORPORATIONS
 
    The chairman of the board, the president, any vice president, the treasurer,
the secretary or assistant  secretary of this corporation,  or any other  person
authorized  by the board of  directors or the president  or a vice president, is
authorized to vote, represent,  and exercise on behalf  of this corporation  all
rights  incident to any and all shares  of any other corporation or corporations
standing in the name  of this corporation. The  authority granted herein may  be
exercised either by such person directly or by any other person authorized to do
so  by  proxy or  power  of attorney  duly executed  by  such person  having the
authority.
 
                                      A-12

                                  ARTICLE VIII
                                GENERAL MATTERS
 
    VIII.1  CHECKS
 
    From time to  time, the  board of  directors shall  determine by  resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment  of money, notes or  other evidences of indebtedness  that are issued in
the name of or payable  to the corporation, and  only the persons so  authorized
shall sign or endorse those instruments.
 
    VIII.2  EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS
 
    The  board of directors,  except as otherwise provided  in these bylaws, may
authorize any  officer  or officers,  or  agent or  agents,  to enter  into  any
contract  or  execute  any  instrument in  the  name  of and  on  behalf  of the
corporation; such 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.
 
    VIII.3  STOCK CERTIFICATES; PARTLY PAID SHARES
 
    The  shares of a 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. 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 were such officer, transfer agent or
registrar at the date of issue.
 
    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, 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.
 
    VIII.4  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  powers,  the
 
                                      A-13

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.
 
    VIII.5  LOST CERTIFICATES
 
    Except as provided in this Section 8.5, no new certificates for shares shall
be issued  to replace  a  previously issued  certificate  unless the  latter  is
surrendered  to the corporation and cancelled  at the same time. The corporation
may issue a new certificate  of stock or uncertificated  shares in the place  of
any  certificate theretofore issued by it, alleged  to have been lost, stolen or
destroyed, and the  corporation may  require the owner  of the  lost, stolen  or
destroyed  certificate, or his  legal representative, to  give the corporation a
bond sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of such new certificate or uncertificated shares.
 
    VIII.6  CONSTRUCTION; DEFINITIONS
 
    Unless the  context requires  otherwise, the  general provisions,  rules  of
construction,  and  definitions in  the Delaware  General Corporation  Law shall
govern the construction of these bylaws. Without limiting the generality of this
provision, the singular number includes  the plural, the plural number  includes
the  singular, and the term  "person" includes both a  corporation and a natural
person.
 
    VIII.7  DIVIDENDS
 
    The directors of the corporation,  subject to any restrictions contained  in
the  certificate of incorporation, may declare and pay dividends upon the shares
of its  capital stock  pursuant  to the  General  Corporation Law  of  Delaware.
Dividends  may be paid in  cash, in property, or  in shares of the corporation's
capital stock.
 
    The directors of the corporation  may set apart out of  any of the funds  of
the  corporation available  for dividends a  reserve or reserves  for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends,  repairing or maintaining  any property of  the
corporation, and meeting contingencies.
 
    VIII.8  FISCAL YEAR
 
    The fiscal year of the corporation shall be fixed by resolution of the board
of directors and may be changed by the board of directors.
 
    VIII.9  SEAL

may be used by causing it or a  facsimile thereof to be impressed or affixed  or
in any other manner reproduced.
 
    VIII.10  TRANSFER OF STOCK
 
    Upon  surrender to the corporation or  the transfer agent of the corporation
of a certificate for shares duly  endorsed or accompanied by proper evidence  of
succession,  assignation 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 in its books.
 
    VIII.11  STOCK TRANSFER AGREEMENTS
 
    The  corporation shall  have power to  enter into and  perform any agreement
with any number  of shareholders  of any  one or more  classes of  stock of  the
corporation  to restrict the transfer  of shares of stock  of the corporation of
any one or more classes owned by such stockholders in any manner not  prohibited
by the General Corporation Law of Delaware.
 
                                      A-14

    VIII.12  REGISTERED STOCKHOLDERS
 
    The  corporation shall  be entitled  to recognize  the exclusive  right of a
person registered on its books as the  owner of shares to receive dividends  and
to  vote  as  such  owner,  shall  be entitled  to  hold  liable  for  calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize  any equitable or other claim  to or interest in  such
share  or shares  on the part  of another person,  whether or not  it shall have
express or other  notice thereof, except  as otherwise provided  by the laws  of
Delaware.
 
                                   ARTICLE IX
                                   AMENDMENTS
 
    The  original or other bylaws of the  corporation may be adopted, amended or
repealed by  the stockholders  entitled  to vote;  provided, however,  that  the
corporation may, in its certificate of incorporation, confer the power to adopt,
amend  or repeal bylaws upon the directors. The fact that such power has been so
conferred upon the directors shall not divest the stockholders of the power, nor
limit their power to adopt, amend or repeal bylaws.
 
                                   ARTICLE X
                                  DISSOLUTION
 
    If it should be deemed advisable in  the judgment of the board of  directors
of  the corporation that  the corporation should be  dissolved, the board, after
the adoption of a resolution to that effect by a majority of the whole board  at
any  meeting called for  that purpose, shall  cause notice to  be mailed to each
stockholder entitled to vote thereon of the adoption of the resolution and of  a
meeting of stockholders to take action upon the resolution.
 
    At  the  meeting  a  vote  shall  be  taken  for  and  against  the proposed
dissolution. If a majority of the outstanding stock of the corporation  entitled
to  vote thereon votes for the  proposed dissolution, then a certificate stating
that the dissolution has  been authorized in accordance  with the provisions  of
Section  275 of the  General Corporation Law  of Delaware and  setting forth the

                                   CUSTODIAN
 
    XI.1  APPOINTMENT OF A CUSTODIAN IN CERTAIN CASES
 
    The Court of Chancery, upon application of any stockholder, may appoint  one
or  more persons to  be custodians and,  if the corporation  is insolvent, to be
receivers, of and for the corporation when:
 
        (i) at any meeting held for  the election of directors the  stockholders
    are  so divided that they have failed to elect successors to directors whose
    terms have  expired  or  would  have expired  upon  qualification  of  their
    successors; or
 
        (ii)  the business of the corporation is suffering or is threatened with
    irreparable injury  because  the directors  are  so divided  respecting  the
    management  of the  affairs of  the corporation  that the  required vote for
    action by the board of directors cannot be obtained and the stockholders are
    unable to terminate this division; or
 
       (iii) the corporation has abandoned its business and has failed within  a
    reasonable  time  to take  steps to  dissolve,  liquidate or  distribute its
    assets.
 
    XI.2  DUTIES OF CUSTODIAN
 
    The custodian shall have  all the powers and  title of a receiver  appointed
under  Section 291 of the General Corporation Law of Delaware, but the authority
of the custodian shall be to continue the business of the corporation and not to
liquidate its  affairs and  distribute  its assets,  except  when the  Court  of
Chancery  otherwise orders and except in  cases arising under Sections 226(a)(3)
or 352(a)(2) of the General Corporation Law of Delaware.
