the meeting during the whole time thereof, and may be inspected by any

with the procedures set forth in this Section 9. No business may be transacted
at any meeting of stockholders, other than business that is either:

(a)      specified in the notice of meeting (or any supplement thereto) given by
         or at the direction of the Board of Directors (or any duly authorized
         committee thereof);

(b)      otherwise properly brought before such meeting of stockholders by or at
         the direction of the Board of Directors (or any duly authorized
         committee thereof); or

(c)      in the case of an annual meeting of stockholders, otherwise properly
         brought before such meeting by any stockholder (i) who is a stockholder
         of record on the date of the giving of the notice provided for in this

         entitled to vote at such annual meeting of stockholders; and (ii) who

Time of Stockholder's Notice. In addition to any other applicable requirements,
such as the requirements set forth in Article III, Section 12 of the
Corporation's bylaws regarding director candidate nominations, for business to
be properly brought before an annual meeting of stockholders by a stockholder,
such stockholder must have given timely notice thereof in proper written form to
the Secretary of the Corporation. To be timely, a stockholder's notice to the
Secretary of the Corporation must be delivered to or mailed and received at the
principal executive offices of the Corporation not later than the close of
business on the ninetieth (90th) day nor earlier than the close of business on
the one hundred twentieth (120th) day prior to the first anniversary of the
immediately preceding year's annual meeting of stockholders; provided, however,
that in the event that the date of the annual meeting of stockholders is more
than thirty (30) days before or more than sixty (60) days after such anniversary
date, notice by the stockholder in order to be timely must be so received not
earlier than the close of business on the one hundred twentieth (120th) day
prior to such annual meeting and not later than the close of business on the
later of the ninetieth (90th) day prior to such annual meeting or the tenth
(10th) day following the day on which public announcement of the date of such
meeting of stockholders was first made. 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. For purpose of this
Section 9, "public announcement" shall mean disclosure in a press release
reported by the

                                        3


Dow Jones News Service, Associated Press or comparable national news service, or
in a document publicly filed by the Corporation with the Securities and Exchange
Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

Notwithstanding anything in the second sentence of the immediately preceding
paragraph 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 bylaw shall also be considered timely, but
only with respect to nominees for any new positions created by such increase, if
it is delivered to the Secretary or mailed and received 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.

Form of Stockholder's Notice. To be in proper written form, a stockholder's
notice to the Secretary of the Corporation must set forth as to each matter such
stockholder proposes to bring before the annual meeting of stockholders: (a) a
brief description of the business desired to be brought before the annual
meeting of stockholders and the reasons for conducting such business at the
annual meeting of stockholders; (b) the name and address of such stockholder and
beneficial owner, if any, as they appear on the Corporation's books; (c) the
class or series and number of shares of capital stock of the Corporation which
are owned beneficially or of record by such stockholder as of the record date
for the meeting (if such date shall then have been made publicly available and
shall have occurred); (d) as of the date of such notice, a description of all
arrangements or understandings between such stockholder and any other person or
persons (including their names) in connection with the proposal of such business
by such stockholder and any material interest of such stockholder in such
business; (e) any other information which would be required to be disclosed in a
proxy statement or other filings required to be made in connection with the
solicitation of proxies for the proposal pursuant to Section 14 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations promulgated thereunder if such stockholder were engaged in such
a solicitation; and (f) a representation that such stockholder intends to appear
in person or by proxy at the annual meeting of stockholders to bring such
business before the meeting.

No business shall be conducted at the annual meeting of stockholders except
business brought before the annual meeting of stockholders in accordance with
the procedures set forth in this Section 9, provided, however, that once
business has been properly brought before the annual meeting of stockholders in
accordance with such procedures, nothing in this Section 9 shall be deemed to
preclude discussion by any stockholder of any such business. If the Chairman of
an annual meeting of stockholders determines that business was not properly
brought before the annual meeting of stockholders in accordance with the
foregoing procedures, the Chairman shall declare to the meeting that the
business was not properly brought before the meeting and such business shall not
be transacted. When a meeting is

                                        4


adjourned to another time or place, notice of the adjourned meeting need not be
given if the time and place thereof are announced at the meeting at which the
adjournment is taken, unless the adjournment is for more than thirty (30) days,
or unless after the adjournment a new record date is fixed for the adjourned
meeting, in which case notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting. At such adjourned meeting
at which a quorum is present or represented, any business may be transacted
which might have been transacted at the original meeting as originally notified.

SECTION 1. POWERS. The business of the Corporation shall be managed by or under
the direction of its Board of Directors, which may exercise all such powers of

or by the Corporation's certificate of incorporation or by these bylaws directed
or required to be exercised or done by the stockholders.

electing officers and transacting any other business properly brought before it,
provided that the organization meeting in any year may be held at a different
time and place than that herein provided by a consent of a majority of the
directors of such new Board of Directors. No notice of such meeting shall be

meeting, provided a quorum shall be present, unless said meeting is not held at
the place of holding and immediately following the annual meeting of

                                        5


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 Corporation's
certificate of incorporation. If a quorum is not present at any meeting of the
Board of Directors, 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.

SECTION 7. CONSENT OF DIRECTORS IN LIEU OF MEETING. Unless otherwise restricted
by the Corporation's certificate of incorporation or these bylaws, any action
required or permitted to be taken at any meeting of the Board of Directors or of
any committee thereof may be taken without a meeting if all members of the Board

the writing or writings are filed with the minutes of proceedings of the Board
of Directors or committee.

SECTION 8. COMMITTEES OF DIRECTORS.

(a) General Authority. The Board of Directors may, to the fullest extent
permitted by Section 141(c)(2) of the Delaware General Corporation Law as the
same may be hereinafter amended from time to time, designate one or more
committees, each committee to consist of one or more of the directors of the
Corporation. The Board of Directors may designate one or more 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 present at any meeting and not
disqualified from voting, whether or not (s)he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the Board of Directors,
or in these bylaws, shall have and may exercise all the powers and authority of
the Board of Directors in the management of the business and affairs of the

authority in reference to the following matters (except as permitted by Delaware
General Corporation Law as the same may be hereinafter amended from time to
time): (i) approving or adopting, or recommending to the stockholders, any
action or matter expressly required to be submitted to stockholders for
approval; or (ii) adopting, amending or repealing any bylaw of the Corporation.

(b) Corporate Governance and Nominating Committee. The Board of Directors shall
establish a Corporate Governance and Nominating Committee of the Board of
Directors. The Corporate Governance and Nominating Committee may: (i) nominate

stockholders called for election of directors (an "Election Meeting"); (ii)
nominate candidates to fill any vacancies on the Board of Directors which may
exist from time to time; and (iii) have such other powers and authority as the
Board of Directors may delegate to it from time to time.

                                        6

meetings and report the same to the Board of Directors when required.

SECTION 10. COMPENSATION OF DIRECTORS. Unless otherwise restricted by the
Corporation's certificate of incorporation, the Board of Directors shall have
authority to fix the compensation of directors. The directors may be paid their
expenses, if any, of attendance at each meeting of the Board of Directors and
may be paid a fixed sum for attendance at each meeting of the Board of Directors
or a stated salary as director. No such payment shall preclude any director from
serving the Corporation in any other capacity and receiving compensation
therefor. Members of special or standing committees may be allowed like
compensation for attending committee meetings.

SECTION 11. PARTICIPATION IN MEETING BY TELEPHONE OR OTHER ELECTRONIC MEDIA.
Unless otherwise restricted by the Corporation's certificate of incorporation or
these bylaws, members of the Board of Directors or any committee designated by
the Board of Directors may participate in a meeting of the Board of Directors or
committee by means of conference telephone, internet conferencing or similar
communications equipment by means of which all persons participating in the
meeting can hear or otherwise communicate with each other, and such
participation in a meeting shall constitute presence in person at such meeting.

SECTION 12. NOMINATIONS OF DIRECTOR CANDIDATES. Only persons who are nominated
in accordance with the following procedures shall be eligible for election as
directors of the Corporation, except as may be otherwise provided in the
Corporation's certificate of incorporation with respect to the right of
directors to fill any vacancies on the Board of Directors, and the right of
holders of preferred stock of the Corporation to nominate and elect a specified
number of directors in certain circumstances. Nominations of persons for
election to the Board of Directors may be made at any annual meeting of
stockholders, or at any special meeting of stockholders called for the purpose
of electing directors, and shall be made:

(a)      by or at the direction of the Board of Directors (or any duly
         authorized committee thereof, including the Corporate Governance and
         Nominating Committee); or

(b)      by any stockholder of the Corporation: (i) who is a stockholder of
         record on the date of the giving of the notice provided for in this
         Section 12 and on the record date for the

                                        7


         determination of stockholders entitled to vote at such meeting; and
         (ii) who complies with the notice procedures set forth in this Section
         12.

In addition to any other applicable requirements, for a nomination to be made by
a stockholder, such stockholder must have given timely notice thereof in proper
written form to the Secretary of the Corporation. To be timely, a stockholder's
notice to the Secretary of the Corporation must be delivered to or mailed and
received at the principal executive offices of the Corporation:

(a)      in the case of an annual meeting of stockholders, not later than the
         close of business on the ninetieth (90th) day nor earlier than the
         close of business on the one hundred twentieth (120th) day prior to the
         first anniversary of the immediately preceding year's annual meeting of
         stockholders; provided, however, that in the event that the date of the
         annual meeting of stockholders is more than thirty (30) days before or
         more than sixty (60) days after such anniversary date, notice by the
         stockholder in order to be timely must be so received not earlier than
         the close of business on the one hundred twentieth (120th) day prior to
         such annual meeting and not later than the close of business on the
         later of the ninetieth (90th) day prior to such annual meeting or the
         tenth (10th) day following the day on which public announcement of the

(b)      in the case of a special meeting of stockholders called for the purpose
         of electing directors, not earlier than the close of business on the
         one hundred twentieth (120th) day prior to such special meeting and not
         later than the close of business on the later of the ninetieth (90th)

         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. For purpose of
         this Section 12, "public announcement" shall mean disclosure in a press
         release reported by the Dow Jones News Service, Associated Press or
         comparable national news service, or reported in a document publicly
         filed by the Corporation with the Securities and Exchange Commission
         pursuant to Section 13, 14 or 15(d) of the Exchange Act.

To be in proper written form, a stockholder's notice to the Secretary of the
Corporation must set forth:

(a)      as to each person whom the stockholder proposes to nominate for
         election as a director: (i) the name, age, business address and
         residence address of the person; (ii) the principal occupation or
         employment of the person; (iii) the class or series and number of
         shares of capital stock of the Corporation which are owned beneficially
         or of record by the person as of the record date for the meeting (if
         such date shall then have been made publicly available and shall have
         occurred) and as of the date of such


                                       8


         notice; and (iv) any other information relating to the person that
         would be required to be disclosed in a proxy statement or other filings
         required to be made in connection with solicitations of proxies for
         election of directors pursuant to section 14 of the Exchange Act, and
         the rules and regulations promulgated thereunder; and


(b)      as to the stockholder giving the notice: (i) the name and address of
         such stockholder and beneficial owner, if any, as they appear on the
         Corporation's books; (ii) the class or series and number of shares of
         capital stock of the Corporation which are owned beneficially or of
         record by such stockholder as of the record date for the meeting (if

         occurred) and as of the date of such notice; (iii) a description of all
         arrangements or understandings between such stockholder and each
         proposed nominee and any other person or persons (including their
         names) pursuant to which the nominations are to be made by such
         stockholder; (iv) a representation that such stockholder intends to
         appear in person or by proxy at the meeting to nominate the persons
         named in its notice; and (v) any other information relating to such

         or other filings required to be made in connection with solicitations
         of proxies for election of directors pursuant to Section 14 of the
         Exchange Act and the rules and regulations promulgated thereunder. Such
         notice must be accompanied by the written consent to such nomination of
         each person proposed as a nominee and such person's written consent to
         serve as a director if elected.

No person shall be eligible for election as a director of the Corporation unless
nominated in accordance with the procedures set forth in this Section 12, or as
otherwise provided in the Corporation's certificate of incorporation with
respect to the right of directors to fill any vacancies on the Board of
Directors, and the right of holders of preferred stock of the Corporation to
nominate and elect a specified number of directors in certain circumstances. If
the Chairman of the meeting determines that a nomination was not made in
accordance with the foregoing procedures, the Chairman shall declare to the
meeting that the nomination was defective and such defective nomination shall be
disregarded.


                                   ARTICLE IV

                                     NOTICES

SECTION 1. NOTICE. Whenever any notice is required to be given to any director
or stockholder under any provision of statute or of the Corporation's
certificate of incorporation or of these bylaws, it shall not be construed to
mean personal notice, but such notice may be given in writing, by mail,
addressed to such director or stockholder, at his address as it appears on the
records of the Corporation, with postage thereon prepaid, and such notice shall
be deemed to be given at the time when the same shall be deposited in the United
States mail. Notice to directors may also be given orally in person or by
electronic mail to the


                                       9


electronic mail address, if any, provided by such director, telegram, telex,
radiogram or cablegram, and such notice shall be deemed to be given when the
recipient receives the notice personally, by telephone or internet or when the
notice, addressed as provided above, has been delivered to the company, or to
the equipment transmitting such notice.

SECTION 2. WAIVER OF NOTICE. Whenever any notice is required to be given under
any provision of statute or of the Corporation's certificate of incorporation or
of these bylaws, a written waiver thereof, signed (manually or electronically by
electronic mail) by the person or persons entitled to said notice, whether
before or after the time stated therein, shall be deemed equivalent to notice.
Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the stockholders, directors, or members of a committee of
directors need be specified in any written waiver of notice unless so required
by the Corporation's certificate of incorporation or these bylaws. 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.


                                    ARTICLE V

so appointed may include a Chairman of the Board, President, one or more Vice
Chairmen, one or more Vice Presidents (including Executive, Senior, First,

         disability of the Chief Executive Officer.

                                       12

SECTION 12. INDEMNIFICATION AND INSURANCE.

(a)      To the fullest extent permitted by these bylaws and by applicable law
         and regulation, as presently existing or hereafter amended, the
         Corporation shall indemnify any person who was or is a party or is
         threatened to be made a party to any threatened, pending or completed
         action, suit or proceeding, whether civil, criminal, administrative or
         investigative (other than an action by or in the right of the
         Corporation), by reason of the fact that he or she is or was a
         director, officer or employee of the Corporation or is or was serving
         at the request of the Corporation as a director, officer, employee or
         agent of another corporation, partnership, joint venture, trust or
         other enterprise, against expenses (including attorneys' fees),
         judgments, fines and amounts paid in settlement actually and reasonably
         incurred by him or her in connection with such action, suit or
         proceeding, if he or she acted in good faith and in a manner he or she
         reasonably believed to be in or not opposed to the best interests of
         the Corporation, and, with respect to any criminal action or
         proceeding, had no reasonable cause to believe his or her conduct was
         unlawful. Any person who is or was an agent of the Corporation may be
         indemnified to the same extent as provided above. In addition, in the
         event any such action, suit or proceeding is threatened or instituted
         against a spouse to whom a director or officer is legally married at
         the time the director or officer is covered under the indemnification
         provided herein, which action, suit or proceeding arises solely out of
         his or her status as the spouse of a director or officer, including,
         without limitation, an action, suit or proceeding that seeks damages
         recoverable from marital community property of the director or officer
         and his or her spouse, property owned jointly by them or property
         purported to have been transferred from the director or officer to his
         or her spouse, then the spouse of the director or officer shall be
         indemnified to the same extent as provided above. At the Corporation's
         election, and in its sole discretion, any person who is or was the
         spouse of an employee or agent of the Corporation may be indemnified to
         the same extent as provided above. The termination of any action, suit
         or proceeding by judgment, order, settlement, conviction or upon a plea
         of nolo contendere or its equivalent, shall not, of itself, create a
         presumption that the person



                                       13


         did not act in good faith and in a manner which he or she reasonably
         believed to be in or not opposed to the best interests of the
         Corporation, and, with respect to any criminal action or proceeding,
         raise any inference that he or she had reasonable cause to believe that
         his or her conduct was unlawful.

(b)      To the fullest extent permitted by these bylaws and by applicable law
         and regulation, as presently existing or hereafter amended, the
         Corporation shall indemnify any person who is or was a party or is
         threatened to be made a party to any threatened, pending or completed
         action or suit by or in the right of the Corporation to procure a
         judgment in its favor, by reason of the fact that he or she is or was a
         director or officer or employee of the Corporation or is or was serving
         at the request of the Corporation as a director, officer, employee or
         agent of another corporation, partnership, joint venture, trust or
         other enterprise, against expenses (including attorneys' fees) actually
         and reasonably incurred by him or her in connection with the defense or
         settlement of such action or suit, if he or she acted in good faith and
         in a manner he or she reasonably believed to be in or not opposed to
         the best interests of the Corporation, and except that no
         indemnification shall be made in respect of any claim, issue or matter
         as to which such person shall have been adjudged to be liable to the
         Corporation unless and only to the extent that the Court of Chancery or
         the court in which such action or suit was brought shall determine upon
         application that, despite the adjudication of liability but in view of
         all the circumstances of the case, such person is fairly and reasonably
         entitled to indemnity for such expenses which the Court of Chancery or
         such other court shall deem proper. Any person who is or was an agent
         of the Corporation may be indemnified to the same extent as provided
         above. In addition, in the event any such action or suit is threatened
         or instituted against a spouse to whom a director or officer is legally
         married at the time the director or officer is covered under the
         indemnification provided herein, which action or suit arises solely out
         of his or her status as the spouse of a director or officer, including,
         without limitation, an action or suit that seeks damages recoverable
         from marital community property of the director or officer and his or
         her spouse, property owned jointly by them or property purported to
         have been transferred from the director or officer to his or her
         spouse, then the spouse of the director or officer shall be indemnified
         to the same extent as provided above. At the Corporation's election,
         and in its sole discretion, any person who is or was the spouse of an
         employee or agent of the Corporation may be indemnified to the same
         extent as provided above.

(c)      To the extent that a present or former director, officer, or spouse of
         the director or officer of the Corporation has been successful on the
         merits or otherwise in defense of any action, suit or proceeding
         referred to in subsections (a) and (b) of this Section, or in defense
         of any claim, issue or matter therein, he or she shall be indemnified
         against expenses (including attorneys' fees) actually and reasonably
         incurred by him or her in connection therewith.


                                       14

(d)      Any indemnification under subsections (a) and (b) of this Section
         (unless ordered by a court) shall be made by the Corporation only as
         authorized in the specific case upon a determination that
         indemnification of the present or former director, officer, spouse of
         the director or officer, employee, agent or spouse of the employee or
         agent is proper in the circumstances because the person has met the
         applicable standard of conduct set forth in subsections (a) and (b) of
         this Section. Unless prohibited by applicable law or regulation, or
         otherwise required by Section 18(k) of the Federal Deposit Insurance
         Act, as amended, such determination shall be made with respect to a
         person who is a director or officer or the spouse of a director or
         officer at the time of the determination (a "D&O Claimant") by
         Independent Legal Counsel (as defined below) in a written opinion to
         the Board of Directors, a copy of which shall be delivered to the D&O
         Claimant, as follows:

         1.       the Disinterested Directors (as defined below) shall select
                  Independent Legal Counsel by majority vote, even if such
                  Disinterested Directors constitute less than a quorum, and
                  direct that the determination be made by such counsel (or, if
                  there are no Disinterested Directors, the full Board of
                  Directors shall select Independent Legal Counsel by majority
                  vote and shall direct that the determination be made by such
                  counsel); unless there shall have occurred within two years
                  prior to the date of the commencement of the Proceeding for
                  which indemnification is claimed a "Change of Control" as
                  defined in the Amended and Restated Comerica Incorporated 1997
                  Long-Term Incentive Plan as in effect on September 24, 2002
                  (or, if applicable, as in effect on such later date as
                  determined by written agreement between the Corporation and
                  the D&O Claimant), in which case the Independent Legal Counsel
                  shall be selected by the D&O Claimant unless the D&O Claimant
                  shall request that such selection be made by the Board of
                  Directors. If it is so determined that the D&O Claimant is
                  entitled to indemnification, payment to the D&O Claimant shall
                  be made within 10 days after such determination.

         2.       the term "Disinterested Directors" shall mean directors that
                  are not and were not parties, and who are not and were not
                  threatened to be made parties, to such Proceeding;

         3.       "Independent Legal Counsel" shall mean a law firm, a member of
                  a law firm, or an independent practitioner, that is
                  experienced in matters of corporation law and that, under the
                  applicable standards of professional conduct then prevailing,
                  would not have a conflict of interest in representing either
                  the Corporation or the D&O Claimant in an action to determine
                  the D&O Claimant's rights under this Section.

         Such determination may be made with respect to any person other than a
         D&O Claimant seeking indemnification under subsections (a) and (b) of
         this Section by the Corporation's Chairman, Chief Executive Officer,
         President, Vice Chairman or General Counsel, or by their designees.

(e)      Expenses (including attorney's fees) incurred by an officer, director
         or spouse of an officer or director in defending any civil, criminal,
         administrative or investigative action, suit or proceeding may be paid
         by the Corporation in advance of the final disposition


                                       15


         of such action, suit or proceeding upon receipt of an undertaking by or
         on behalf of the director, officer or spouse to repay such amount if it
         shall ultimately be determined that he or she is not entitled to be
         indemnified by the Corporation as authorized in this Section. Such
         expenses (including attorneys' fees) incurred by former directors or
         officers, their spouses or other employees and agents may be so paid
         upon such terms and conditions, if any, as the Corporation deems
         appropriate.

(f)      The indemnification and advancement of expenses provided by, or granted
         pursuant to, the other subsections of this Section shall not be deemed
         exclusive of any other rights to which those seeking indemnification or
         advancement of expenses may be entitled under any bylaw, agreement,
         vote of stockholders or Disinterested Directors or otherwise, both as
         to action in his or her official capacity and as to action in another
         capacity while holding such office.

(g)      The Corporation may purchase and maintain insurance on behalf of any
         person who is or was a director, officer, spouse of a director or
         officer, employee or agent of the Corporation, or is or was serving at
         the request of the Corporation as a director, officer, employee or
         agent of another corporation, partnership, joint venture, trust or
         other enterprise against any liability asserted against such person and
         incurred by such person 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 such person against such liability under the provisions of
         this Section.

(h)      For the purposes of this Section, references to "the Corporation"
         include, in addition to the resulting or surviving corporation, any
         constituent corporation (including any constituent of a constituent)
         absorbed in a consolidation or merger which, if its separate existence
         had continued, would have had the power and authority to indemnify its
         directors, officers, spouses of directors or officers, and employees or
         agents, so that any person who is or was a director, officer, spouse of
         a director or officer, employee or agent of such constituent
         corporation, or is or was serving at the request of such constituent
         corporation as a director, officer, employee, or agent of another
         corporation, partnership, joint venture, trust or other enterprise,
         shall stand in the same position under the provisions of this Section
         with respect to the resulting or surviving corporation as he or she
         would have with respect to such constituent corporation if its separate
         existence had continued.

(i)      For purposes of this Section, references to "other enterprises" shall
         include employee benefit plans; references to "fines" shall include any
         excise taxes assessed on a person with respect to an employee benefit
         plan; and references to "serving at the request of the Corporation"
         shall include any service as a director, officer, employee or agent of
         the Corporation which imposes duties on, or involves services by, such
         director, officer, employee, or agent with respect to an employee
         benefit plan, its participants, or beneficiaries; and a person who
         acted in good faith and in a manner he or she reasonably believed to be
         in the interest of the participants and beneficiaries


                                       16


         of an employee benefit plan shall be deemed to have acted in a manner
         "not opposed to the best interests of the Corporation" as referred to
         in this Section.

(j)      The indemnification and advancement of expenses provided by, or granted
         pursuant to, this Section shall, unless otherwise provided when
         authorized or ratified, continue as to a person who has ceased to be a
         director, officer, employee or agent, and with respect to any spouse of
         a director or officer, shall continue following the time the director
         or officer spouse ceases to be a director or officer even if the
         marriage of the individuals terminates prior to the end of the period
         of coverage, and shall inure to the benefit of the heirs, executors and
         administrators of such a person.

(k)      The Court of Chancery shall have exclusive jurisdiction to hear and
         determine all actions for advancement of expenses or indemnification
         brought under this Section or under any agreement, vote of stockholders
         or Disinterested Directors, or otherwise. The Court of Chancery may
         summarily determine the Corporation's obligation to advance expenses
         (including attorneys' fees).


                                   ARTICLE VI

                               STOCK AND TRANSFERS

SECTION 1. CERTIFICATES OF STOCK. Shares of the Corporation's stock may be
certificated or uncertificated, as provided under Delaware law at any time. All
certificated shares of stock shall exhibit on the certificate the holders' name
and number of shares and shall be signed by, or in the name of the Corporation
by the Chairman or a Vice Chairman of the Board of Directors, or the President
or a Vice President, and by the Treasurer or an Assistant Treasurer, or the
Secretary or an Assistant Secretary of the Corporation. Any or all the
signatures on the certificate may be by facsimile. In case any officer, transfer
agent or registrar who has signed or whose facsimile signature has been placed
upon a certificate shall have 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 such person were such officer, transfer agent or
registrar at the date of issue. All holdings of shares of stock of the
Corporation shall be numbered and shall be entered into the books of the
Corporation as they are issued. If the Corporation shall be authorized to issue
more than one class of stock or more than one series of any class, the powers,
designations, preferences and 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 which the
Corporation may issue to represent such class or series of stock or, in the case
of uncertificated shares, contained in a written notice that shall be sent to
the registered owner within a reasonable time after the issuance or transfer of
such uncertificated stock, provided 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
which the

                                       17


Corporation may issue to represent such class or series of stock or, in the case
of uncertificated shares, contained in the written notice sent to the registered
holder as set forth above, a statement that the Corporation will furnish without
charge to each stockholder who so requests the powers, designations, preferences
and 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.

SECTION 2. LOST CERTIFICATES. The Board of Directors may direct a new
certificate to be issued in place of any certificate theretofore issued by the
Corporation, alleged to have been lost, stolen or destroyed, upon the making of
an affidavit of that fact by the person claiming the certificate of stock to be
lost, stolen or destroyed. When authorizing the issuance of a new certificate
the Board of Directors may, in its discretion and as a condition precedent to
the issuance thereof, require the owner of such lost, stolen or destroyed
certificate, or his legal representative, to advertise the same in such manner
as it shall require and/or to give the Corporation a bond in such sum as it may
direct as indemnity against any claim that may be made against it with respect
to the certificate alleged to have been lost, stolen or destroyed.

SECTION 3. TRANSFERS OF STOCK. The Corporation shall make transfers of stock on
the Corporation's books only by the record holder of such stock or by his or her
