transmission in the manner provided in Section 232 of the Delaware General
Corporation Law. 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 in such
affidavit.

         Section 2.5.      Voting List. The officer who has charge of the stock

and outstanding and entitled to vote at meetings of the stockholders, 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 shall
not be present or represented at any meeting of the stockholders, the
stockholders entitled to vote at such meeting, 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 shall be present
or represented. At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified. If the adjournment is for more than 30 days,
or if after the adjournment a new record date is fixed for the adjourned

listed (and in the absence of the first, the next, and so on), shall serve as
chairman of the meeting: president, chairman of the board, vice presidents (in
the order of their seniority if more than one), and secretary. The order of
business at each such meeting shall be as determined by the chairman of the
meeting. The chairman of the meeting shall have the right and authority to
prescribe such rules, regulations, and procedures and to do all such acts and
things as are necessary or desirable for the proper conduct of the meeting,
including, without limitation, the establishment of

                                       2

restrictions on entry to such meeting after the time prescribed for the
commencement of such meeting, and the opening and closing of the voting polls.

         Section 2.10.     Majority Vote. 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 statutes or of the Certificate of Incorporation, a different vote is
required, in which case such express provision shall govern and control the
decision of such question.

         Section 2.11.     Method of Voting. Unless otherwise provided in the
Certificate of Incorporation, each stockholder shall at every meeting of the
stockholders be entitled to one vote in person or by proxy for each share of the
capital stock having voting power held by such stockholder, but no proxy shall
be voted on after three years from its date, unless the proxy provides for a
longer period.

the Delaware General Corporation Law, setting forth the action so taken, shall
be signed by 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

voted and shall be delivered to the Corporation by delivery to its registered
office in Delaware, its principal place of business or an officer or agent of

made to a Corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested.

         Section 2.13.     Presence at Meetings. If authorized by the Board of
Directors in its sole discretion, and subject to such guidelines and procedures
as the Board may adopt, stockholders and proxyholders not physically present at
the meeting of stockholders may by means of remote communication (1) participate
in a meeting of stockholders and (2) be deemed present in person and vote at a
meeting of stockholders whether such meeting is to be held at a designated place
or solely by means of remote communication, provided that (i) the Corporation
shall implement reasonable measures to verify that each person deemed present
and permitted to vote at the meeting by means of remote communication is a
stockholder or proxyholder, (ii) the Corporation shall implement reasonable
measures to provide such stockholders and proxyholders a reasonable opportunity
to participate in the meeting and to vote on matters submitted to the

the board of directors, the directors present at such meeting may adjourn the
meeting from time to time, without notice other than announcement at the

in office, even though less than a quorum of the board of directors,

                                       5



or by a sole remaining director, and newly created directorships resulting from
any increase in the number of directors shall be filled by the board of
directors, or if not so filled, by the stockholders at the next annual meeting
of the stockholders or at a special meeting called for that purpose in
accordance with Section 2.6 of Article 2 of these Bylaws. Any director elected

restricted by the Certificate of Incorporation or these Bylaws, the board of
directors shall have the 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 for such service. Members of special or
standing committees may be allowed like compensation for attending committee
meetings.

business and affairs of the Corporation, including, if such committee is so
empowered and authorized by resolution adopted by a majority of the entire
board, the power and authority to declare a dividend and to authorize the
issuance of stock, and may authorize the seal of the Corporation to be affixed
to all papers which may require it, except that the executive committee shall

                  (a)      amending the Certificate of Incorporation of the
         Corporation;

         Section 4.2.      Other Committees. The board of directors may, by
resolution adopted by a majority of the entire board, designate from among its
members one or more other committees, each of which shall, except as otherwise
prescribed by law, have such authority of the board as may be specified in the
resolution of the board designating such committee. A majority of all the
members of such committee may determine its action and fix the time and place of
its meetings, unless the board shall otherwise provide. The board shall have the

committee shall be present at such meeting. Notice of any adjourned meeting of
any committee of the board need not be given. The executive committee or any
other committee of the board may adopt such rules and regulations not
inconsistent with the provisions of law, the Certificate of Incorporation of the
Corporation, or these Bylaws for the conduct of its meetings as the executive
committee or any other committee of the board may deem proper. A majority of the
executive committee or any other committee of the board shall constitute a
quorum for the transaction of business at any meeting, and the vote of a
majority of the members of such committee present at any meeting at which a
quorum is present shall be the act of such committee. In the absence or
disqualification of a member, the remaining members, whether or not a quorum,
may fill a vacancy. The executive committee or any other committee of the board
of directors shall keep written minutes of its proceedings, a copy of which is
to be filed with the secretary of the Corporation, and shall report on such
proceedings to the board.

secretary, shall have authority to affix the same to any instrument requiring it
and when so affixed, it may be attested by his signature or by the signature of
such assistant secretary. The board of directors may give general authority to
any other officer to affix the seal of the Corporation and to attest the
affixing by his signature.

         Section 6.10.     Assistant Secretary. The assistant secretary, or if
there be more than one, the assistant secretaries in the order determined by the
board of directors (or if there be no such determination, then in the order of
their election) shall, in the absence of the secretary or in the event of his
inability or refusal to act, perform the duties and exercise the powers of the
secretary and shall perform such other duties and have such other powers as the
board of directors may from time to time prescribe.

                                       9



         Section 6.11.     Treasurer. The treasurer, if there be such an
officer, shall have the custody of the corporate funds and securities and shall
keep full and accurate accounts of receipts and disbursements in books belonging
to the Corporation and shall deposit all moneys and other valuable effects in
the name and to the credit of the Corporation in such depositories as may be
designated by the board of directors. He shall disburse the funds of the
Corporation as may be ordered by the board of directors, taking proper vouchers
for such disbursements, and shall render to the president and the board of
directors, at its regular meetings, or when the board of directors so requires,
an account of all his transactions as treasurer and of the financial condition
of the Corporation. If required by the board of directors, he shall give the
Corporation a bond in such sum and with such surety or sureties as shall be
satisfactory to the board of directors for the faithful performance of the
duties of his office and for the restoration to the Corporation, in case of his
death, resignation, retirement, or removal from office, of all books, papers,
vouchers, money, and other property of whatever kind in his possession or under
his control belonging to the Corporation. If there is not a treasurer of the
Corporation, then the duties set forth above shall be discharged by the
President or such other officer as shall be designated by the board of
directors.

         Section 6.12.     Assistant Treasurer. The assistant treasurer, or if
there shall be more than one, the assistant treasurers in the order determined
by the board of directors (or if there be no such determination, then in the
order of their election), shall, in the absence of the treasurer or in the event
of his inability or refusal to act, perform the duties and exercise the powers
of the treasurer and shall perform such other duties and have such other powers
as the board of directors may from time to time prescribe.

                                   ARTICLE 7

                          INDEMNIFICATION OF DIRECTORS,
                         OFFICERS, EMPLOYEES, AND AGENTS

         Section 7.1.      Third-Party Actions. 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 such person is or was a
director or officer of the Corporation, or 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, against all expenses (including
attorney's fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit, or
proceeding if such person acted in good faith and in a manner such person
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. 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 did not act in good faith and in a manner which such
person reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, that such
person had reasonable cause to believe that his or her conduct was unlawful.

                                       10



         The Corporation may indemnify any employee or agent of the Corporation,
or any employee or agent serving at the request of the Corporation as an
employee or agent of another corporation, partnership, joint venture, trust, or
other enterprise, in the manner and to the extent that it shall indemnify any
director or officer under this Section.

         Section 7.2.      Derivative Actions. The Corporation may indemnify any
person who was or is 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 such
person 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 all expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection with the defense or settlement
of such action or suit if such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
Corporation, except that no indemnification shall be made with respect to any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of such person's duty to
the Corporation unless and only to the extent that the Court of Chancery of
Delaware 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 of Delaware or such
other court shall deem proper.

         Section 7.3.      Determination of Indemnification. Any indemnification
under Section 7.1 or Section 7.2 of this Article (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 director, officer, employee, or agent
is proper in the circumstances because such person has met the applicable
standard of conduct set forth in Section 7.1 or Section 7.2 of this Article.
Such determination shall be made (i) by the board of directors by a majority
vote of a quorum consisting of directors who were not parties to such action,
suit, or proceeding, or (ii) if such a quorum is not obtainable, or, even if
obtainable, a quorum of disinterested directors so directs, by independent legal
counsel in a written opinion, or (iii) by the stockholders.

         Section 7.4.      Right to Indemnification. Notwithstanding the other
provisions of this Article, to the extent that a director, officer, employee, or
agent of the Corporation has been successful on the merits or otherwise in
defense of any action, suit, or proceeding referred to in Section 7.1 or Section
7.2 of this Article, or in defense of any claim, issue, or matter in any such
claim or issue, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
with such defense.

         Section 7.5.      Advance of Expenses. Expenses incurred in defending a
civil or criminal action, suit, or proceeding may be paid by the Corporation on
behalf of a director, officer, employee, or agent in advance of the final
disposition of such action, suit, or proceeding as authorized by the board of
directors in the specific case upon receipt of an undertaking by or on behalf of
the director, officer, employee, or agent to repay such amount unless it shall
ultimately be determined that such person is entitled to be indemnified by the
Corporation as authorized in this Article.

                                       11



         Section 7.6.      Indemnification Not Exclusive. The indemnification
provided by this Article shall not be deemed exclusive of any other rights to
which any person seeking indemnification may be entitled under any law,
agreement, vote of stockholders or disinterested directors, or otherwise, both
as to action in such person's official capacity and as to action in another
capacity while holding such office, and shall continue as to a person who has
ceased to be a director, officer, employee, or agent and shall inure to the
benefit of the heirs, executors, and administrators of such a person.

         Section 7.7.      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 such person and incurred by such person in any such capacity,
or arising out of such person's status as such, whether or not the Corporation
would have the power to indemnify such person against liability under the
provisions of this Article.

         Section 7.8.      Definitions of Certain Terms. For purposes of this
Article, references to "the Corporation" shall include, in addition to the
resulting 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 power and authority to indemnify its
directors, officers, employees, or agents, so that any person who is or was a
director, 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 Article with respect to the resulting or surviving
corporation as such person would have with respect to such constituent
corporation if its separate existence had continued.

         For purposes of this Article, 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; 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 such person reasonably believed
to be in the interest of the participants and beneficiaries 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 Article.

         Section 7.9.      Liability of Directors. Notwithstanding any provision
of the Certificate of Incorporation or any other provision in these Bylaws, no
director shall be personally liable to the Corporation or any stockholder for
monetary damages for breach of fiduciary duty as a director, except for any
matter in respect of which such director shall be liable under Section 174 of
Title 8 of the Delaware Code (relating to the Delaware General Corporation Law)
or any amendment or successor provision to such provision or shall be liable by
reason that, in addition to any and all other requirements for such liability,
he (i) shall have breached his duty of loyalty to the Corporation or its
stockholders, (ii) shall not have acted in good faith, (iii) shall have acted in
a manner involving intentional misconduct

                                       12



or a knowing violation of law or, in failing to act, shall have acted in a
manner involving intentional misconduct or a knowing violation of law or (iv)
shall have derived an improper personal benefit.

                                   ARTICLE 8

                              CERTIFICATES OF STOCK

         Section 8.1.      Certificates. Every holder of stock in the
Corporation 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 a vice president and the treasurer or an assistant
treasurer, or the secretary or an assistant secretary of the Corporation,
certifying the number of shares owned by him in the Corporation.

         Section 8.2.      Facsimile Signatures. Any of or all the signatures on
the certificate may be 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 he were such officer, transfer agent, or registrar at the date
of issue.

         Section 8.3.      Lost Certificates. The board of directors may direct
a new certificate or certificates to be issued in place of any certificate or
certificates previously 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 such issue of a new certificate or certificates, the board of
directors may, in its discretion and as a condition precedent to the issuance of
such new certificate or certificates, require the owner of such lost, stolen, or
destroyed certificate or certificates, 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 the Corporation with respect to the certificate alleged to have
been lost, stolen, or destroyed.

         Section 8.4.      Transfers 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, assignment, or
authority to transfer, it shall be the duty of the Corporation to issue a new
certificate to the person entitled to such certificate, cancel the old
certificate and record the transaction upon its books.

         Section 8.5.      Fixing Record Date. In order that the Corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
stockholders or any adjournment of any meeting of stockholders, or to express
consent to corporate action in writing without a meeting, or to receive payment
of any dividend or other distribution or allotment of any rights, or 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 60 nor less than 10 days before the
date of such meeting, nor more than 60 days prior to any other action. 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
that the board of directors may fix a new record date for the adjourned meeting.

                                       13



         Section 8.6.      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, and to hold
liable for calls and assessments a 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 any other person, whether or
not it shall have express or other notice of such claim or interest, except as
otherwise provided by the laws of Delaware.

                                   ARTICLE 9

                             AFFILIATED TRANSACTIONS

         Section 9.1.      Validity. Except as otherwise provided for in the
Certificate of Incorporation and except as otherwise provided in these Bylaws,
if Section 9.2 is satisfied, no contract or transaction between the Corporation
and any of its directors, officers, or security holders, or any corporation,
partnership, association, or other organization in which any of such directors,
officers, or security holders are directly or indirectly financially interested,
shall be void or voidable solely because of this relationship, or solely because
of the presence of the director, officer, or security holder at the meeting
authorizing the contract or transaction, or solely because of his or their
participation in the authorization of such contract or transaction or vote at
the meeting for authorization of such contract or transaction, whether or not
such participation or vote was necessary for the authorization of such contract
or transaction.

         Section 9.2.      Disclosure, Approval, Fairness. Section 9.1 shall
apply only if:

                  (a)      the material facts as to the relationship or interest
         and as to the contract or transaction are disclosed or are known:

                           (i)      to the board of directors (or committee of
                  the board of directors) and it nevertheless in good faith
                  authorizes or ratifies the contract or transaction by a
                  majority of the directors present, each such interested
                  director to be counted in determining whether a quorum is
                  present but not in calculating the majority necessary to carry
                  the vote; or

                           (ii)     to the stockholders and they nevertheless
                  authorize or ratify the contract or transaction by a majority
                  of the shares present at a meeting considering such contract
                  or transaction, each such interested person (stockholder) to
                  be counted in determining whether a quorum is present and for
                  voting purposes; or

                  (b)      the contract or transaction is fair to the
         Corporation as of the time it is authorized or ratified by the board of
         directors (or committee of the board of directors) or the stockholders.

         Section 9.3.      Nonexclusive. This provision shall not be construed
to invalidate a contract or transaction which would be valid in the absence of
this provision.
