      Section 2.4. Annual Meeting. Nominations of persons for election to the
Board of Directors and the proposal of business to be transacted by the
stockholders at an annual meeting of stockholders may be made (i) pursuant to
the Corporation's notice with respect to such meeting, (ii) by, or at the
direction of, the Board of Directors or (iii) by any stockholder of record of
the Corporation who was a stockholder of record at the time of the giving of the
notice provided for in the following paragraph, who is entitled to vote at the
meeting and who has complied with the notice procedures set forth in this
Article II, Section 2.4.

      For nominations or other business to be properly brought before an annual
meeting by a stockholder pursuant to clause (iii) of the foregoing paragraph,
(a) the stockholder must have given timely notice thereof in writing to the
Secretary of the Corporation at the principal executive offices of the
Corporation, (b) such business must be a proper matter for stockholder action
under the General Corporation Law of the State of Delaware, (c) if the
stockholder, or the beneficial owner on whose behalf any such proposal or
nomination is made, has provided the Corporation with a Solicitation Notice, as
that term is defined in this Article II, Section 2.4, such stockholder or
beneficial owner must, in the case of a proposal, have delivered a proxy
statement and form of proxy to holders of at least the percentage of the
Corporation's voting shares required under applicable law to carry any such
proposal, or, in the case of a nomination or nominations, have delivered a proxy
statement and form of proxy to holders of a percentage of the Corporation's
voting shares reasonably believed by such stockholder or beneficial holder to be
sufficient to elect the nominee or nominees proposed to be nominated by such
stockholder (the number of voting shares required to carry the proposal or elect
the nominees being the "Required Number"), and must, in either case, have
included in such materials the Solicitation Notice and (d) if no Solicitation
Notice relating thereto has been timely provided pursuant to this Article II,
Section 2.4, the stockholder or beneficial owner proposing such business or
nomination must not have solicited proxies for a number of shares equal to or
greater than the Required Number. To be timely, a stockholder's notice shall be
delivered to the Secretary of the Corporation at the principal executive offices
of the Corporation not less than forty-five (45) or more than seventy-five (75)
days prior to the first anniversary (the "Anniversary") of the date on which the
Corporation first mailed its proxy materials for the preceding year's annual
meeting of stockholders; provided, however, that if the date of the annual
meeting is advanced more than thirty (30) days prior to, or delayed by more than
thirty (30) days after, the anniversary of the preceding year's annual meeting,
notice by the stockholder to be timely must be so delivered not later than the
close of business on the later of (i) the 90th day prior to such annual meeting
or (ii) the 10th day following the day on which public announcement of the date
of such annual meeting is first made. Such stockholder's notice shall set forth
(a) as to each person whom the stockholder proposes to nominate for election or
reelection as a director, all information relating to such person as would be
required to be disclosed in solicitations of proxies for the election of such
nominees as directors pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and such person's written consent
to serve as a director if elected; (b) as to any other business that the
stockholder proposes to bring before the meeting, a brief description of such
business, the reasons for conducting such business at

                                                                     Exhibit 3.2

the meeting and any material interest in such business of such stockholder and
the beneficial owner, if any, on whose behalf the proposal is made; and (c) as
to the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (i) the name and address of such
stockholder, as they appear on the Corporation's books, and of such beneficial
owner, (ii) the class and number of shares of the Corporation that are owned
beneficially and of record by such stockholder and such beneficial owner, and
(iii) whether either such stockholder or beneficial owner intends to deliver a
proxy statement and form of proxy to holders of, in the case of a proposal, at
least the percentage of the Corporation's voting shares required under
applicable law to carry the proposal or, in the case of a nomination or
nominations, a sufficient number of holders of the Corporation's voting shares
to elect such nominee or nominees (an affirmative statement of such intent, a
"Solicitation Notice").

      Notwithstanding anything in the second sentence of the second paragraph of
this Article II, Section 2.4 to the contrary, in the event that the number of
directors to be elected to the Board of Directors 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
fifty-five (55) days prior to the Anniversary, a stockholder's notice required
by these By-laws shall also be considered timely, but only with respect to
nominees for any new positions created by such increase, if it shall be
delivered to the Secretary of the Corporation 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.

      Only persons nominated in accordance with the procedures set forth in this
Article II, Section 2.4 shall be eligible to serve as directors, and only such
business shall be conducted at an annual meeting of stockholders as shall have
been brought before the meeting in accordance with the procedures set forth in
this Article II, Section 2.4. The chair of the meeting shall have the power and
the duty to determine whether a nomination or any business proposed to be
brought before the meeting has been made in accordance with the procedures set
forth in these By-laws and, if any proposed nomination or business is not in
compliance with these By-laws, to declare that such defective proposed business
or nomination shall not be presented for stockholder action at the meeting and
shall be disregarded.

      For purposes of these By-laws, "public announcement" shall mean disclosure
in a press release reported by the Dow Jones News Service, Associated Press or a
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.

      Section 2.5. Special Meeting. Only such business shall be conducted at a
special meeting of stockholders as shall have been brought before the meeting
pursuant to the Corporation's notice of meeting. Nominations of persons for
election to the Board of Directors may be made at a special meeting of
stockholders at which directors are to be elected pursuant to the Corporation's
notice of meeting (i) by or at the direction of the

<PAGE>

                                                                     Exhibit 3.2

Board of Directors or (ii) by any stockholder of record of the Corporation who
is a stockholder of record at the time of giving notice provided for in this
paragraph, who shall be entitled to vote at the meeting and who complies with
the notice procedures set forth in Article II, Section 2.4. Nominations by
stockholders of persons for election to the Board of Directors may be made at
such a special meeting of stockholders if the stockholder's notice required by
the second paragraph of Article II, Section 2.4 shall be delivered to the
Secretary of the Corporation at the principal executive offices of the
Corporation not later than the close of business on the later of the 90th day
prior to such special meeting or the 10th day following the day on which public
announcement is first made of the date of the special meeting and of the
nominees proposed by the Board of Directors to be elected at such meeting.

      Notwithstanding the foregoing provisions of Article II, Sections 2.4 and
2.5, a stockholder shall also comply with all applicable requirements of the
Exchange Act and the rules and regulations thereunder with respect to matters
set forth in Article II, Sections 2.4 and 2.5. Nothing in Article II, Sections
2.4 and 2.5 shall be deemed to affect any rights of stockholders to request
inclusion of proposals in the Corporation's proxy statement pursuant to Rule
14a-8 under the Exchange Act.

      Section 2.6. Special Meetings of the Stockholders. Special meetings of the
stockholders of the Corporation may be called only by (i) the Chairman of the
Board, (ii) the President, (iii) the Chief Executive Officer or (iv) the Board
of Directors pursuant to a resolution approved by a majority of the Board of
Directors. The business transacted at any special meeting of the stockholders
shall be limited to the purposes stated in the notice for the meeting
transmitted to stockholders.

      Section 2.7. Notice of Special Meetings. Written notice of a special
meeting stating the place, date and hour of the meeting and the purpose or
purposes for which the meeting is called, shall be given by the Secretary of the
Corporation, not fewer than ten (10) nor more than sixty (60) days before the
date of the meeting, to each stockholder entitled to vote at such meeting.

      Section 2.8. Fixing of 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 thereof, 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 a
record date, which shall not precede the date upon which the resolution fixing
the record date is adopted and which shall be (i) not more than sixty (60) nor
less than ten (10) days before the date of a meeting, and (ii) not more than
sixty (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, however, that the Board of
Directors may fix a new record date for any adjourned meeting.

                                                                     Exhibit 3.2

      Section 2.9. Voting Lists. The officer who has charge of the stock ledger
of the Corporation shall prepare and make, at least ten (10) days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting (i) during ordinary business hours, at the
principal place of business of the Corporation, or (ii) as otherwise permitted
by law. 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.

      Section 2.10. Quorum and Adjournments. The holders of a majority of the
voting power of the stock issued and outstanding and entitled to vote thereat,
present in person or represented by proxy, shall constitute a quorum at all
meetings of the stockholders for the transaction of business, except as
otherwise provided by statute or by the Corporation's Certificate of
Incorporation. If, however, such quorum shall not be present or represented at
any such meeting of the stockholders, the holders of a majority of the voting
power of the stock 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 shall be present or
represented; provided that if the adjournment is for more than thirty (30) days,
or if after the adjournment a new record date is fixed by the directors for the
adjourned meeting, a new notice shall be transmitted to the stockholders of
record entitled to vote at the adjourned meeting. 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.

      Section 2.11. Vote Required. When a quorum is present at any meeting of
stockholders, the affirmative vote of the holders of a majority of the voting
power of the stock issued and outstanding and entitled to vote thereat, 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 statute
or of the Corporation's Certificate of Incorporation, a different vote is
required, in which case such express provision shall govern and control the
decision of such question; provided, however, all elections of directors shall
be determined by a plurality of the votes cast.

      Section 2.12. Voting Rights. Unless otherwise provided in the
Corporation's Certificate of Incorporation, each stockholder having voting power
shall at every meeting of the stockholders be entitled to one (1) 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 (3) years from its date,
unless the proxy provides for a longer period. At any meeting of the
stockholders, every stockholder entitled to vote may vote in person or by proxy
authorized by an instrument in writing or by a transmission permitted by law
filed in accordance with the procedure established for the meeting. Any copy,
facsimile telecommunication or other reliable reproduction of the writing or
transmission created

                                                                     Exhibit 3.2

pursuant to this paragraph may be substituted or used in lieu of the original
writing or transmission for any and all purposes for which the original writing
or transmission could be used; provided that such copy, facsimile
telecommunication or other reproduction shall be a complete reproduction of the
entire original writing or transmission. All voting, including on the election
of directors, may (except where otherwise required by law) be by a voice vote;
provided, however, that upon demand therefor by a stockholder entitled to vote
or by his or her proxy, a stock vote shall be taken. Every stock vote shall be
taken by ballots, each of which shall state the name of the stockholder or proxy
voting and such other information as may be required under the procedure
established for the meeting. The Corporation may, and to the extent required by
law shall, in advance of any meeting of stockholders, appoint one or more
inspectors to act at the meeting and make a written report thereof. The
Corporation may designate one or more persons as alternate inspectors to replace
any inspector who fails to act. If no inspector or alternate is able to act at a
meeting of stockholders, the person presiding at the meeting may, and to the
extent required by law shall, appoint one or more inspectors to act at the
meeting. Each inspector, before entering upon the discharge of his or her
duties, shall take and sign an oath to faithfully execute the duties of
inspector with strict impartiality and according to the best of his or her
ability. Every vote taken by ballots shall be counted by an inspector or
inspectors appointed by the chairman of the meeting.

      Section 2.13. Presiding Over Meetings. The Chairman of the Board of
Directors shall preside at all meetings of the stockholders. In the absence or
inability to act of the Chairman, the Vice Chairman, the President or a Vice
President (in that order) shall preside, and in their absence or inability to
act another person designated by one of them shall preside. The Secretary of the
Corporation shall act as secretary of each meeting of the stockholders. In the
event of his or her absence or inability to act, the chairman of the meeting
shall appoint a person who need not be a stockholder to act as secretary of the
meeting.

      Section 2.14. Conducting Meetings. Meetings of the stockholders shall be
conducted in a fair manner but need not be governed by any prescribed rules of
order. The presiding officer of the meeting shall establish an agenda for the
meeting. The presiding officer's rulings on procedural matters shall be final.
The presiding officer is authorized to impose reasonable time limits on the
remarks of individual stockholders and may take such steps as such officer may
deem necessary or appropriate to assure that the business of the meeting is
conducted in a fair and orderly manner.

      Section 2.15. Informal Action. Prior to the completion of the
Corporation's initial public offering of its equity securities registered under
the Securities Act of 1933, as amended (a "Public Offering"), any action
required or permitted to be taken at any meeting of the stockholders may be
taken without a meeting as provided in Article VI, A. of the Corporation's
Certificate of Incorporation. Upon completion of an initial Public Offering by
the Corporation, this Section 2.15 shall be of no further force and effect.

      Section 3.1. General Powers. The business and affairs of the Corporation
shall be under the direction of, and managed by, a board comprised of directors,
which may exercise all such powers of the Corporation and do all such lawful
acts and things as are not required by statute, by the Corporation's Certificate
of Incorporation or by these By-laws to be done by the stockholders. Directors

Corporation. The number of directors shall be determined in the manner provided
in the Corporation's Certificate of Incorporation.

offering, Directors shall be elected for one (1) year terms. Upon completion of
an initial public offering, Directors shall be elected by class for three (3)
year or other terms as specified in the Corporation's Certificate of
Incorporation, and each director elected shall hold office during the term for
which he or she is elected and until his or her successor is elected and
qualified, subject, however, to his or her prior death, resignation, retirement
or removal from office.

      Section 3.3. Chairman and Vice Chairmen of the Board of Directors. The
Board of Directors may elect a Chairman from among the directors. The Chairman
shall possess and exercise such authority and powers and perform such duties as
may be determined by these By-laws and the Board of Directors. The Board of
Directors may determine that the Chairman shall be a non-executive of the
Corporation, in which event he shall not be an officer of the Corporation.

      The Board of Directors may elect one or more Vice Chairmen of the Board of
Directors. The Vice Chairman shall possess and exercise such authority and
powers and perform such duties as may be determined by these By-laws and the
Board of Directors. The Board of Directors may determine that the Vice Chairman
shall be a non-executive of the Corporation, in which event he shall not be an
officer of the Corporation.

      Section 3.4. Removal. Directors may only be removed as provided in the
Corporation's Certificate of Incorporation.

      Section 3.5. Vacancies. Any vacancies occurring in the Board of Directors
and newly created directorships shall be filled in the manner provided in the
Corporation's Certificate of Incorporation.

      Section 3.6. Place of Meetings. The Board of Directors of the Corporation
may hold meetings, both regular and special, either within or without the State
of Delaware. The first meeting of each newly elected Board of Directors shall be

stockholders at the same place as such annual meeting and no notice of such
meeting shall be necessary to the newly elected directors in order to legally
constitute the meeting, provided a quorum shall be

                                                                     Exhibit 3.2

present. In the event such meeting is not held at such time and place, the
meeting may be held at such time and place as shall be specified in a notice
given as hereinafter provided for special meetings of the Board of Directors, or
as shall be specified in a written waiver signed by all of the directors.

      Section 3.7. Participation by Conference Telephone. Unless otherwise
restricted by the Corporation's Certificate of Incorporation or these By-laws,
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 or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and
participation by such means shall constitute presence in person at such meeting.

      Section 3.8. Regular Meetings. Regular meetings of the Board of Directors
may be held, without notice, at such time and at such place as shall from time
to time be determined by the Board of Directors.

      Section 3.9. Special Meetings. Special meetings of the Board of Directors

called by the Chairman, the Chief Executive Officer or the President in like
manner and on like notice at the written request of two or more of the directors
comprising the Board of Directors stating the purpose or purposes for which such
meeting is requested. Notice of any meeting of the Board of Directors for which
a notice is required may be waived in writing signed by the person or persons
entitled to such notice, whether before or after the time of such meeting, and
such waiver shall be equivalent to the giving of such notice. Attendance of a
director at any such meeting shall constitute a waiver of notice thereof, except
where a director attends a meeting for the express purpose of objecting to the
transaction of any business because such meeting is not lawfully convened.
Neither the business to be transacted at, nor the purpose of, any meeting of the
Board of Directors for which a notice is required need be specified in the
notice, or waiver of notice, of such meeting. The Chairman shall preside at all
meetings of the Board of Directors. In the absence or inability to act of the
Chairman, then the Vice Chairman (if one shall have been chosen by the Board),
the Chief Executive Officer, the President or the Chief Financial Officer (in
that order) shall preside, and in their absence or inability to act, another
director designated by one of them shall preside.

      Section 3.10. Quorum; No Action on Certain Matters. At all meetings of the
Board of Directors, a majority of the then duly elected 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 Corporation's Certificate of Incorporation. If a quorum
shall not be 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 shall be present.

      Section 3.11. Resignations. Any director of the Corporation may resign at
any time by giving written notice to the Board of Directors, the Chairman or the
President. Such resignation shall take effect at the time specified therein and,
unless tendered to take effect upon acceptance thereof, the acceptance of such
resignation shall not be necessary to make it effective.

      Section 3.12. Informal Action. Unless otherwise restricted by the
Corporation's Certificate of Incorporation or these By-laws, 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 of
Directors or committee, as the case may be, consent thereto in writing or by
electronic transmission, and the writing or writings or electronic transmission
or transmissions are filed with the minutes of proceedings of the Board of
Directors or committee. Such filings shall be in paper form if the minutes are
maintained in paper form and in electronic form if the minutes are maintained in
electronic form.

      Section 3.13. Presumption of Assent. A director of the Corporation who is
present at a meeting of the Board of Directors at which action on any corporate
matter is taken shall be conclusively presumed to have assented to the action
taken unless his or her dissent shall be entered in the minutes of the meeting
or unless he or she shall file his or her written dissent to such action with
the person acting as the secretary of the meeting before the adjournment thereof
or shall forward such dissent by registered mail to the secretary of the
Corporation immediately after the adjournment of the meeting. Such right to
dissent shall not apply to a director who voted in favor of such action.

      Section 3.14. Compensation of Directors. In the discretion of the Board of
Directors, the directors may be paid their expenses, if any, of attendance at
each meeting of the Board of Directors or a committee thereof, may be paid a
stated salary or a fixed sum for attendance at each meeting of the Board of
Directors or a committee thereof and may be awarded other compensation for their
service as directors. No such payment or award 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.

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 thereof
present at any meeting and not disqualified from voting, whether or not such
member or members 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, 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 Corporation; but no such committee shall have the power or
authority in reference to the following matters: (a) approving or adopting, or
recommending to the stockholders, any action or matter expressly required by the
Delaware General Corporation Law to be submitted to stockholders for approval or
(b) adopting, amending or repealing any of the By-laws.

      Section 4.2. Committee Minutes. Each committee may keep regular minutes of
its meetings and shall file such minutes and all written consents executed by

of, the Corporation by (a) the Chairman of the Board, the Vice-Chairman of the
Board or the President of the Corporation, and (b) the Secretary, the Treasurer,
an Assistant Secretary or an Assistant Treasurer of the Corporation, certifying
the number of shares owned by such holder in the Corporation. If the Corporation

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 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
which 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, designations, preferences and relative,
participating, optional or other special rights of each class of stock or series

registrar who has signed, or whose facsimile signature has been placed upon, a

same effect as if such person were such officer, transfer agent or registrar at

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
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or such

alleged to have been lost, stolen or destroyed.

      Section 7.4. Transfers of Stock. Upon surrender to the Corporation or the

in such share or shares on the part of any other person, whether or not the

the Corporation and any other corporation, partnership, association or other
organization in which one or more of its directors or officers are directors or
officers or have a financial interest shall be void or voidable solely for this
reason, or solely because such director or officer is present at, or
participates in, the meeting of the Board of Director's or committee thereof

or officer's vote is counted for such purpose, if:

            or interest and as to the contract or transaction are disclosed or
            are known to the Board of Directors or the committee, and the board
            or committee in good faith authorizes the contract or transaction by
            the affirmative vote of a majority of the disinterested directors,
            even though the disinterested directors be less than a quorum; or

            contract or transaction is specifically approved in good faith by
            vote of the stockholders; or
