                                    ARTICLE 1

                            MEETINGS OF STOCKHOLDERS

       1.1    Place of Meetings. All meetings of stockholders shall be held at
such place within or without the State of Delaware as may be designated from
time to time by the Board of Directors or the President or, if not so
designated, at the registered office of the corporation.

       1.2    Annual Meeting. The annual meeting of stockholders for the
election of directors and for the transaction of such other business as may
properly be brought before the meeting shall be held each year on a date and at
a time designated by the Board of Directors or the President. In the absence of
such designation, the annual meeting of stockholders shall be held on the
first,Monday in May in each year at 10:00 a.m. However, if such day falls on a
legal holiday, then the meeting shall be held at the same time and place on the
next succeeding business day.

       1.3    Special Meetings. Special meetings of stockholders may be called
at any time by the President or by the Board of Directors. No other person or
persons are permitted to call a special meeting.

              If a special meeting is called by any person or persons other than
the board of directors, then the request shall be in writing, specifying the
time of such meeting and the general nature of the business proposed to be
transacted, and shall be delivered personally or sent by registered mail or by
telegraphic or other facsimile transmission to the chairman of the board, the
president, or the secretary of the corporation. The officer receiving the
request shall cause notice to be promptly given to the stockholders entitled to
vote, in accordance with the provisions of Sections 1.4 and 1.6 of these bylaws,
that a meeting will be held at the time requested by the person or persons
calling the meeting, so long as that time is not less than thirty-five (35) nor
more than sixty (60) days after the receipt of the request. If the notice is not
given within twenty (20) days after receipt of the request, then the person or
persons requesting the meeting may give the notice. Nothing contained in this
paragraph of this Section 1.3 shall be construed as limiting, fixing or
affecting the time when a meeting of stockholders called by action of the board
of directors may be held.

       1.4    Notice of Meetings. All notices of meetings of stockholders shall
be sent or otherwise given in accordance with Section 1.6 of these bylaws not

to each stockholder entitled to vote at such meeting. The notices of all
meetings shall state the place, date and hour of the meeting. The notice of a
special meeting shall specify the place date and hour of meeting and (i) in the
case of a special meeting, the purpose or purposes for which the meeting is
called (no business other than that specified in the notice may be transacted)
or (ii) in the case of the annual meeting, those matters which the board of
directors, at the time of giving the notice, intends to present for action by
the stockholders (but any proper matter may be presented at the meeting for such
action). The notice of any meeting at which directors are to be elected shall
include the name of any nominee or nominees who, at the time of the notice, the
board intends to present for election.

       1.5    Advance Notice of Stockholder Nominees and Stockholder Business.
Subject to the rights of holders of any class or series of stock having a
preference over the Common Stock as to dividends or upon liquidation,

              (1)    nominations for the election of directors, and

              (2)    business proposed to be brought before any stockholder
meeting may be made by the board of directors or proxy committee appointed by
the board of directors or by any stockholder entitled to vote in the election of
directors generally if such nomination or business proposed is otherwise proper
business before such meeting. However, any such stockholder may nominate one or
more persons for election as directors at a meeting or propose business to be
brought before a meeting, or both, only if such stockholder has given timely
notice in proper written form of their intent to make such nomination or
nominations or to propose such business. To be timely, such stockholder's notice
must be delivered to or mailed and received at the principal executive offices
of the corporation not less than one hundred twenty (120) calendar days in
advance of the date specified in the corporation's proxy statement released to
stockholders in connection with the previous year's annual meeting of
stockholders; provided, however, that in the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than thirty (30) days from the date contemplated at the time of the
previous year's proxy state ment, notice by the stockholder to be timely must be
so received a reasonable time before the solicitation is made. To be in proper
form, a stockholder's notice to the secretary shall set forth:

                     (i)    the name and address of the stockholder who intends
       to make the nominations or propose the business and, as the case may be,
       of the person or persons to be nominated or of the business to be
       proposed;

                     (ii)   a representation that the stockholder is a holder of
       record of stock of the corporation entitled to vote at such meeting and,
       if applicable, intends to appear in person or by proxy at the meeting to
       nominate the person or persons specified in the notice;


                                      -2-
   7
                     (iii)  if applicable, a description of all arrangements or
       understandings between the stockholder and each nominee and any other
       person or persons (naming such person or persons) pursuant to which the
       nomination or nominations are to be made by the stockholder;

                     (iv)   such other information regarding each nominee or
       each matter of business to be proposed by such stockholder as would be
       required to be included in a proxy statement filed pursuant to the proxy
       rules of the Securities and Exchange Commission had the nominee been
       nominated, or intended to be nominated, or the matter been proposed, or
       intended to be proposed by the board of directors; and

                     (v)    if applicable, the consent of each nominee to serve
       as director of the corporation if so elected.

        The chairman of the meeting shall refuse to acknowledge the nomination
of any person or the proposal of any business not made in compliance with the
foregoing procedure.

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

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

       1.7    Quorum. The holders of a majority in voting power of the stock
issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at all meetings of the
stockholders for the transaction of business except as otherwise pro vided by
statute or by the certificate of incorporation. If, however, such quorum is not
present or represented at any meeting of the stockholders, then either (i) the
chairman of the meeting or (ii) the stockholders entitled to vote thereat,
present in person or represented by proxy, shall have power to adjourn the
meeting in accordance with Section 1.7 of these bylaws.

              When a quorum is present at any meeting, the vote of the holders
of a majority of the stock having voting power present in person or represented
by proxy shall decide any question brought before such meeting, unless the
question is one upon which, by express provision of the laws of the State of
Delaware or of the certificate of incorporation or these bylaws, a different
vote is required, in which case such express provision shall govern and control
the decision of the question.


                                      -3-
   8
              If a quorum be initially present, the stockholders may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

       1.8    Adjournments. Any meeting of stockholders may be adjourned to any
other time and place at which a meeting of stockholders may be held under these
bylaws. Unless these bylaws otherwise require, it shall not be necessary to
notify any stockholder of any adjournment of less than 30 days if the time and
place of the adjourned meeting are announced at the meeting at which adjournment
is taken. At the adjourned meeting, the corporation may transact any business
which might have been transacted at the original meeting. If the adjournment is
for more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

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

              Except as may be otherwise provided in the certificate of
incorporation or these bylaws, each stockholder shall be entitled to one vote
for each share of capital stock held by such stockholder and stockholders shall
not be entitled to cumulate their votes in the election of directors or with
respect to any matter submitted to a vote of the stockholders.

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


                                      -4-
   9
              If the board of directors does not so fix a record date, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the business day
next preceding the day on which notice is given, or, if notice is waived, at the
close of business on the business day next preceding the day on which the
meeting is held.

              A determination of stockholders of record entitled to notice of or
to vote at a meeting of stockholders shall apply to any adjournment of the
meeting unless the board of directors fixes a new record date for the adjourned
meeting, but the board of directors shall fix a new record date if the meeting
is adjourned for more than thirty (30) days from the date set for the original
meeting.

              The record date for any other purpose shall be as provided in
Section 7.1 of these bylaws.

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

       1.13   Organization. The president, or in the absence of the president,
the chairman of the board, or, in the absence of the president and the chairman
of the board, one of the corporation's vice presidents, shall call the meeting
of the stockholders to order, and shall act as chairman of the meeting. In the
absence of the president, the chairman of the board, and all of the vice
presidents, the stockholders shall appoint a chairman for such meeting. The
chairman of any meeting of stockholders shall determine the order of business
and the procedures at the meeting, including such matters as the regulation of
the manner of voting and the conduct of business. The secretary of the
corporation shall act as secretary of all meetings of the stockholders, but in
the absence of the secretary at any meeting of the stockholders, the chairman of
the meeting may appoint any person to act as secretary of the meeting.

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


                                      -5-

       1.15   Waiver of Notice. Whenever notice is required to be given under
any provision of the General Corporation Law of Delaware or of the certificate
of incorporation or these bylaws, a written waiver thereof, signed by the person
entitled to notice, whether before or after the time stated therein, shall be
deemed equivalent to notice. Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when the person attends a
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders need be specified in any written
waiver of notice unless so required by the certificate of incorporation or these
bylaws.


                                    ARTICLE 2

                                    DIRECTORS

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

       2.2    Number; Election and Qualification.

              (a)    The board of directors shall consist of five (5) members.
The number of directors may be changed by an amendment to this bylaw, duly
adopted by the board of directors or by the stockholders, or by a duly adopted
amendment to the certificate of incorporation. If the number of directors is
hereafter changed, any newly created directorships or decrease in directorships
shall be so apportioned among the classes as to make all classes as nearly equal
in number as is practicable, provided that no decrease in the number of
directors constituting the board of directors shall shorten the term of any
incumbent director.

              (b)    Upon the closing of the first sale of the corporation's
common stock pursuant to a firmly underwritten registered public offering (the
"IPO"), the directors shall be divided into three classes, with the term of
office of the first class, which class shall initially consist of two directors,
to expire at the first annual meeting of stockholders held after the IPO; the
term of office of the second class, which class shall initially consist of one
director, to expire at the second annual meeting of stockholders held after the
IPO; the term of office of the third class, which class shall initially consist
of two directors, to expire at the third annual meeting of stockholders held
after the IPO; and thereafter for each such term to expire at each third
succeeding annual meeting of stockholders held after such election.

       2.3    Election and Term of Office of Directors. Except as provided in
Section 2.4 of these bylaws, directors shall be elected at each annual meeting
of stockholders to hold office as provided


                                      -6-
   11
in Section 2.4 of these bylaws. Each director, including a director elected or
appointed to fill a vacancy, shall hold office until the expiration of the term
for which elected and until a successor has been elected and qualified.

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

              Vacancies in the board of directors may be filled by a majority of
the remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote of
the stockholders or by court order may be filled only by the affirmative vote of
a majority of the shares represented and voting at a duly held meeting at which
a quorum is present (which shares voting affirmatively also constitute a
majority of the required quorum). Each director so elected shall hold office for
a term expiring at the next annual meeting of the stockholders at which the term
of office of the class to which such director has been elected expires.

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

              (i)    Vacancies and newly created directorships resulting from
any increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

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

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

              If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole board (as constituted immediately prior to any such increase), then
the Court of Chancery may, upon application of any stockholder or


                                      -7-
   12
stockholders holding at least ten (10) percent of the total number of the shares
at the time outstanding having the right to vote for such directors, summarily
order an election to be held to fill any such vacancies or newly created
directorships, or to replace the directors chosen by the directors then in
office as aforesaid, which election shall be governed by the provisions of
Section 211 of the General Corporation Law of Delaware as far as applicable.

       2.5    Removal of Directors. Except as otherwise provided by the General
Corporation Law of Delaware, any one or more or all of the directors may be
removed, with or without cause, by the holders of a majority of the shares then
entitled to vote at an election of directors, provided, however, that, if and so
long as stockholders of the corporation are entitled to cumulative voting, if
less than the entire board is to be removed, no director may be removed without
cause if the votes cast against his removal would be sufficient to elect him if
then cumulatively voted at an election of the entire board of directors.

       2.6    Place of Meetings; Meetings by Telephone. Regular meetings of the
board of directors may be held at any place within or outside the State of
Delaware that has been designated from time to time by resolution of the board.
In the absence of such a designation, regular meetings shall be held at the
principal executive office of the corporation. Special meetings of the board may
be held at any place within or outside the State of Delaware that has been
designated in the notice of the meeting or, if not stated in the notice or if
there is no notice, at the principal executive office of the corporation.

conference telephone or similar communication equipment, so long as all
directors participating in the meeting can hear one another; and all such
participating directors shall be deemed to be present in person at the meeting.

       2.7    First Meetings. The first meeting of each newly elected board of
directors shall be held at such time and place as shall be fixed by the vote of
the stockholders at the annual meeting. In the event of the failure of the
stockholders to fix the time or place of such first meeting of the newly elected
board of directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, 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.

                                 GENERAL MATTERS

       7.1    Record Date for Purposes Other than Notice and Voting. For
purposes of determining the stockholders entitled to receive payment of any
dividend or other distribution or allotment of any rights or the stockholders
entitled to exercise any rights in respect of any change, conversion or exchange
of stock, or for the purpose of any other lawful action, the board of directors
may fix, in advance, a record date, which shall not precede the date upon which
the resolution fixing the record date is adopted and which shall not be more
than sixty (60) days before any such action. In that case, only stockholders of
record at the close of business on the date so fixed are entitled to receive the
dividend, distribution or allotment of rights, or to exercise such rights, as
the case may be, notwith-


                                      -16-
   21
standing any transfer of any shares on the books of the corporation after the
record date so fixed, except as otherwise provided by law.

              If the board of directors does not so fix a record date, then the
record date for determining stockholders for any such purpose shall be at the
close of business on the day on which the board of directors adopts the
applicable resolution.

       7.2    Checks; Drafts; Evidences of Indebtedness. From time to time, the
board of directors shall determine by resolution which person or persons may
sign or endorse all checks, drafts, other orders for payment of money, notes or
other evidences of indebtedness that are issued in the name of or payable to the
corporation, and only the persons so authorized shall sign or endorse those
instruments.

       7.3    Corporate Contracts and Instruments; How Executed. The board of
directors, except as otherwise provided in these bylaws, may authorize and
empower any officer or officers, or agent or agents, to enter into any contract
or execute any instrument in the name of and on behalf of the corporation; such
power and authority may be general or confined to specific instances. Unless so
authorized or ratified by the board of directors or within the agency power of
an officer, no officer, agent or employee shall have any power or authority to
bind the corporation by any contract or engagement or to pledge its credit or to
render it liable for any purpose or for any amount.

       7.4    Stock Certificates; Transfer; Partly Paid Shares. The shares of
the corporation shall be represented by certificates, provided that the board of
directors of the corporation may provide by resolution or resolutions that some
or all of any or all classes or series of its stock shall be uncertificated
shares. Any such resolution shall not apply to shares represented by a
certificate until such certificate is surrendered to the corporation.
Notwithstanding the adoption of such a resolution by the board of directors,
every holder of stock represented by certificates and, upon request, every
holder of uncertificated shares, shall be entitled to have a certificate signed
by, or in the name of the corporation by, the chairman or vice-chairman of the
board of directors, or the president or vice-president, and by the treasurer or
an assistant treasurer, or the secretary or an assistant secretary of such
corporation representing the number of shares registered in certificate form.
Any or all of the signatures on the certificate may be a facsimile. In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate has ceased to be such officer, transfer agent
or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he or she were such officer, transfer
agent or registrar at the date of issue.

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


                                      -17-
   22
statement as to any applicable voting trust agreement; if the shares be
assessable, or, if assessments are collectible by personal action, a plain
statement of such facts.

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

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

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

       7.6    Lost certificates. Except as provided in this Section 7.6, no new
certificates for shares shall be issued to replace a previously issued
certificate unless the latter is surrendered to the corporation and canceled at
the same time. The board of directors may, in case any share certificate or
certificate for any other security is lost, stolen or destroyed, authorize the
issuance of replacement certificates on such terms and conditions as the board
may require; the board may require indemnification of the corporation secured by
a bond or other adequate security sufficient to protect the corporation against
any claim that may be made against it, including any expense or liability, on
account of the alleged loss, theft or destruction of the certificate or the
issuance of the replacement certificate.

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


                                      -18-

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


                                    ARTICLE 8

                                   AMENDMENTS

       The original or other bylaws of the corporation may be adopted, amended
or repealed by the stockholders entitled to vote or by the board of directors of
the corporation. The fact that such power has been so conferred upon the
directors shall not divest the stockholders of the power, nor limit their power
to adopt, amend or repeal bylaws.

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