                        INTEGRATED TELECOM EXPRESS, INC.
                            (a Delaware corporation)

                                    ARTICLE I

         1.2       OTHER OFFICES

         The board of directors may at any time establish other offices at any
place or places where the corporation is qualified to do business.

                                   ARTICLE II
                            MEETINGS OF STOCKHOLDERS

         2.1       PLACE OF MEETINGS

         Meetings of stockholders shall be held at any place, within or outside
the State of Delaware, designated by the board of directors. In the absence of
any such designation, stockholders' meetings shall be held at the principal
executive office of the corporation.

         2.2       ANNUAL MEETING

         The annual meeting of stockholders shall be held each year on a date
and at a time designated by the board of directors. At the meeting, directors
shall be elected and any other proper business may be transacted.

         2.3      SPECIAL MEETING

         A special meeting of the stockholders for any purpose or purposes may
be called by the President or Secretary, or by resolution of the directors, or
by vote of the stockholders holding fifty (50%) or more of the outstanding
stock.

<PAGE>

         2.4      NOTICE OF STOCKHOLDERS' MEETINGS

         All notices of meetings with stockholders shall be in writing and
shall be sent or otherwise given in accordance with Section 2.5 of these bylaws
not less than ten (10) nor more than sixty (60) days before the date of the
meeting to each stockholder entitled to vote at such meeting. The notice shall
specify the place, date, and hour of the meeting, and, in the case of a special
meeting, the purpose or purposes for which the meeting is called.

         2.5      MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

         Written notice of any meeting of stockholders, if mailed, is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the secretary or an assistant secretary or of the transfer agent
of the corporation that the notice has been given shall, in the absence of
fraud, be prima facie evidence of the facts stated therein.

         2.6      QUORUM

         The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the certificate of
incorporation. If, however, such quorum is not present or represented at any
meeting of the stockholders, then the stockholders entitled to vote thereat,
present in person or represented by proxy, shall have power to adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum is present or represented. At such adjourned meeting at
which a quorum is present or represented, any business may be transacted that
might have been transacted at the meeting as originally noticed.

         2.7      ADJOURNED MEETING; NOTICE

         When a meeting is adjourned to another time or place, unless these
bylaws otherwise require, notice need not be given of the adjourned meeting if
the time and place thereof are announced at the meeting at which the
adjournment is taken. At the adjourned meeting the corporation may transact any
business that might have been transacted at the original meeting. If the
adjournment is for more than thirty (30) days, or if after the adjournment a
new record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.

         2.8      VOTING

         The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of Section 2.11 of these
bylaws, subject to the provisions of Sections 217 and 218 of the General
Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors
and joint owners of stock and to voting trusts and other voting agreements).

                                       -2-
<PAGE>

         2.9      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.

         2.10      STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Unless otherwise provided in the certificate of incorporation, any
action required by this chapter to be taken at any annual or special meeting of
stockholders of the corporation, or any action that may be taken at any annual
or special meeting of such stockholders, may be taken without a meeting, without
prior notice, and without a vote if a consent in writing, setting forth the
action so taken, is signed by the holders of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all shares entitled to vote thereon were
present and voted.

         Prompt notice of the taking of the corporate action without a meeting
by less than unanimous written consent shall be given to those stockholders who
have not consented in writing. If the action which is consented to is such as
would have required the filing of a certificate under any section of the General
Corporation Law of Delaware if such action had been voted on by stockholders at
a meeting thereof, then the certificate filed under such section shall state, in
lieu of any statement required by such section concerning any vote of
stockholders, that written notice and written consent have been given as
provided in Section 228 of the General Corporation Law of Delaware.

         In the event of the delivery, in the manner provided hereby, to the
corporation of the requisite written consent or consents to take corporate
action and/or any related revocation or revocations, the corporation may engage
independent inspectors of elections for the purpose of performing promptly a
ministerial review of the validity of the consents and revocations. For the
purpose of permitting the inspectors to perform such review, in the event such
inspectors are appointed, no action by written consent without a meeting shall
be effective until such date as such appointed independent inspectors certify
to the corporation that the consents delivered to the corporation in accordance
herewith represent at least the minimum number of votes that would be necessary
to take the corporate action. Nothing contained in these Bylaws shall in any
way be construed to suggest or imply that the board of directors or any
stockholder shall not be entitled to contest the validity of any consent or
revocation thereof, whether before or after any certification by any
independent inspectors, or to take any other action (including, without
limitation, the commencement, prosecution or defense of any litigation with
respect thereto, and the seeking of injunctive relief in such litigation).

                                       -3-
<PAGE>

         Every written consent shall bear the date of signature of each
stockholder who signs the consent and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty (60) days of
the earliest dated written consent received in accordance herewith, a written
consent or consents signed by a sufficient number of holders to take such action
are delivered to the corporation in the manner prescribed herein.

         2.11      RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

              (a)      ACTIONS OTHER THAN WRITTEN CONSENT. For the purpose of
determining 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 the allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion, or exchange of stock,
or other lawful purpose (other than the expression of consent to corporate
action in writing without a meeting) the directors may fix, in advance, a
record date, which, in the case of a meeting of stockholders, shall not be more
than 60 days nor less than 10 days before the date of such meeting. If no
record date is fixed, the record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held and the record date for determining stockholders for
any other purpose pursuant to this Section 2.11(a) shall be at the close of
business on the day on which the board of directors adopts the resolution
relating thereto. A determination of stockholders of record entitled to notice
of or to vote at any meeting of stockholders shall apply to any adjournment of
the meeting; provided, however, that the board of directors may fix a new
record date for the adjourned meeting.

              (b)      ACTION BY WRITTEN CONSENT. In order that the corporation
may determine the stockholders entitled to consent to corporate action in
writing without a meeting, the board of directors may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors. Any stockholder of record
seeking to have the stockholders authorize or take corporate action by written
consent shall, by written notice to the secretary, request the board of
directors to fix a record date. The board of directors may, at any time within
ten (10) days after the date on which such a request is received, adopt a
resolution fixing the record date (unless a record date has previously been
fixed by the first sentence of this Section 2.11(b)). If no record date has
been fixed by the board of directors pursuant to the first sentence of this
Section 2.11(b) or otherwise within ten (10) days of the date on which such a
request is received, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting, when no prior action
by the board of directors is required by applicable law, shall be the first
date on which a signed written consent setting forth the action taken or
proposed to be taken is delivered to the corporation by delivery to its
registered office in Delaware, its principal place of business, or to any
officer or agent of the corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery shall be by hand
or by certified or registered mail, return receipt requested. If no record date
has been fixed by the board of directors and prior action by the board of
directors is required by

                                       -4-

<PAGE>

applicable law, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting shall be at the
close of business on the date on which the board of directors adopts the
resolution taking such prior action.

         2.12     PROXIES

         Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for him by a written proxy, signed by
the stockholder and filed with the secretary of the corporation, but no such
proxy shall be voted or acted upon after three (3) years from its date, unless
the proxy provides for a longer period. A proxy shall be deemed signed if the
stockholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the stockholder or the
stockholder's attorney-in-fact. The revocability of a proxy that states on its
face that it is irrevocable shall be governed by the provisions of Section
212(c) of the General Corporation Law of Delaware.

         2.13     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.

         2.14     NOMINATIONS AND PROPOSALS

         Nominations of persons for election to the board of directors of the
corporation and the proposal of business to be considered by the stockholders
may be made at any meeting of stockholders only (a) pursuant to the
corporation's notice of meeting, (b) by or at the direction of the board of
directors or (c) by any stockholder of the corporation who was a stockholder of
record at the time of giving of notice provided for in these bylaws, who is
entitled to vote at the meeting and who complies with the notice procedures set
forth in this Section 2.14.

         For nominations or other business to be properly brought before a
stockholders meeting by a stockholder pursuant to clause (c) of the preceding
sentence, the stockholder must have given timely notice thereof in writing to
the secretary of the corporation and such other business must otherwise be a
proper matter for stockholder action. To be timely, a stockholder's notice shall
be delivered to the secretary at the principal executive offices of the
corporation not later than the close of business on the 60th day nor earlier
than the close of business on the 90th day prior to the meeting; provided,
however, that in the event that less than 65 days notice of the meeting is given

notice by the stockholder to be timely must be so delivered not earlier than
the close of business on the seventh (7th) day following the day on which the
notice of meeting was mailed. In no event shall the public announcement of an

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

named in the proxy statement as a nominee and to serving as a director if
elected); (b) as to any other business that the stockholder proposes to bring
before the meeting, a brief description of the business desired to be brought
before the meeting, the reasons for conducting such business at the meeting

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, and (ii) the class and number of shares of the corporation

         3.1      POWERS

         Subject to the provisions of the General Corporation Law of Delaware
and 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.

         3.2      NUMBER OF DIRECTORS

         Unless otherwise provided in the Company's Certificate of
Incorporation, the authorized number of directors shall be seven (7). This
number may be changed by a duly adopted amendment to the certificate of
incorporation or by an amendment to this bylaw adopted by the vote or written
consent of the holders of a majority of the stock issued and outstanding and
entitled to vote or by resolution of a majority of the board of directors.

         No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

                                    -6-
<PAGE>

         3.3      ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS

         Except as provided in the certificate of incorporation and Section 3.4
of these bylaws, directors shall be elected at each annual meeting of
stockholders to hold office until the next annual meeting. Directors need not be
stockholders unless so required by the certificate of incorporation or these
bylaws, wherein other qualifications for directors may be prescribed. Each
director, including a director elected to fill a vacancy, shall hold office
until his successor is elected and qualified or until his earlier resignation or
removal.

         Elections of directors need not be by written ballot.

         3.4      RESIGNATION AND VACANCIES

         Any director may resign at any time upon written notice to the
corporation. When one or more directors so resigns and the resignation is
effective at a future date, a majority of the directors then in office,
including those who have so resigned, shall have power to fill such vacancy or
vacancies, the vote thereon to take effect when such resignation or resignations
shall become effective, and each director so chosen shall hold office as
provided in this section in the filling of other vacancies.

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

                  (a) 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.

                  (b) 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 stockholders
holding at least ten (10) percent of the total number of the shares at the time
outstanding having the

                                    -7-
<PAGE>

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.

         3.5      PLACE OF MEETINGS; MEETINGS BY TELEPHONE

         The board of directors of the corporation may hold meetings, both
regular and special, either within or outside the State of Delaware.

         Unless otherwise restricted by the 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 any 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 such participation in a meeting shall constitute presence in
person at the meeting.

         3.6      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 and no notice of such meeting shall be necessary to the newly
elected directors in order legally to constitute the meeting, provided a quorum
shall be present. 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.

         3.7      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

         Special meetings of the board of directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two (2) directors.

         Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally or by
telephone or by telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be

                                      -8-
<PAGE>

communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director. The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

         3.9      QUORUM

         At all meetings of the board of directors, a majority of the authorized
number of directors shall constitute a quorum for the transaction of business
and the act of a majority of the directors present at any meeting at which there
is a quorum shall be the act of the board of directors, except as may be
otherwise specifically provided by statute or by the certificate of
incorporation. If a quorum is not present at any meeting of the board of
directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

         3.10     WAIVER OF NOTICE

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

         3.11     ADJOURNED MEETING; NOTICE

         If a quorum is not present at any meeting of the board of directors,

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

the board or committee.

         3.13     FEES AND COMPENSATION OF DIRECTORS

otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing contained in this section shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

         3.15     REMOVAL OF DIRECTORS

         Unless otherwise restricted by statute, by the certificate of

         The board of directors may, by resolution passed by a majority of the
whole board, designate one or more committees, with each committee to consist of
one or more of the directors of the corporation. The board may designate one or

or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the board of
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 the bylaws of the corporation, 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, and may authorize the
seal of the corporation to be affixed to all papers that may require it; but no
such committee shall have the power or authority to (i) amend the certificate of
incorporation (except that a committee may, to the extent authorized in the
resolution or resolutions providing for the issuance of shares of stock adopted
by the board of directors as provided in Section 151(a) of the General
Corporation Law of Delaware, fix any of the preferences or rights of such shares
relating to dividends, redemption, dissolution, any distribution of assets of
the corporation or the conversion into, or the exchange of such shares for,
shares of any other class or classes or any other series of the same or any
other class or classes of stock of the corporation), (ii) adopt an agreement of
merger or consolidation under Sections 251 or 252 of the General Corporation Law
of Delaware, (iii) recommend to the stockholders the sale, lease or exchange of
all or substantially all of the

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

         4.2      COMMITTEE MINUTES

time of regular meetings of committees may also be called by resolution of the
board of directors and that notice of special meetings of committees shall also
be given to all alternate members, who shall have the right to attend all
meetings of the committee. The board of directors may adopt rules for the
government of any committee not inconsistent with the provisions of these
bylaws.

such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder. The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

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

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

         7.2      INSPECTION BY DIRECTORS

         Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his position as a director. The Court of Chancery
is hereby vested with the exclusive jurisdiction to determine whether a director
is entitled to the inspection sought. The Court may summarily order the
corporation to permit the director to inspect any and all books and records, the
stock ledger, and the stock list and to make copies or extracts therefrom. The
Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

         7.3      ANNUAL STATEMENT TO STOCKHOLDERS

         The board of directors shall present at each annual meeting, and at any
special meeting of the stockholders when called for by vote of the stockholders,
a full and clear statement of the business and condition of the corporation.

         7.4      REPRESENTATION OF SHARES OF OTHER CORPORATIONS

         The chairman of the board, the president, any vice president, the chief
financial officer, the secretary or assistant secretary of this corporation, or
any other person authorized by the board of directors or the president or a vice
president, is authorized to vote, represent, and exercise on behalf of this
corporation all rights incident to any and all shares of any other corporation
or corporations standing in the name of this corporation. The authority granted
herein may be exercised either by such person directly or by any other person
authorized to do so by proxy or power of attorney duly executed by such person
having the authority.

                                  ARTICLE VIII
                                 GENERAL MATTERS

         8.1      CHECKS

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

         8.2      EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS

         The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific

                                    -16-
<PAGE>

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.

         8.3      STOCK CERTIFICATES; 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 chief
financial officer or controller, or the secretary or an assistant secretary of
such corporation representing the number of shares registered in certificate
form. Any or all of the signatures on the certificate may be a facsimile. In
case any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate has ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if he were such officer, transfer
agent or registrar at the date of issue.

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

         8.4      SPECIAL DESIGNATION ON CERTIFICATES

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

         8.5      LOST CERTIFICATES

         Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate theretofore issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of such new certificate or uncertificated shares.

         8.6      CONSTRUCTION; DEFINITIONS

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

         8.7      DIVIDENDS

         The directors of the corporation, subject to any restrictions contained
in the certificate of incorporation, may declare and pay dividends upon the
shares of its capital stock pursuant to the General Corporation Law of Delaware.
Dividends may be paid in cash, in property, or in shares of the corporation's
capital stock.

         The directors of the corporation may set apart out of any of the funds
of the corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

         8.8      FISCAL YEAR

         The fiscal year of the corporation shall be fixed by resolution of the
board of directors and may be changed by the board of directors.

         8.9      SEAL

         This corporation may have a corporate seal, which may be adopted or
altered at the pleasure of the board of directors, and may use the same by
causing it or a facsimile thereof, to be impressed or affixed or in any other
manner reproduced.

         8.10     TRANSFER OF STOCK

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

         8.11     STOCK TRANSFER AGREEMENTS

         The corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the corporation to restrict the transfer of shares of stock of the corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the General Corporation Law of Delaware.

         8.12     REGISTERED STOCKHOLDERS

         The corporation shall be entitled to recognize the exclusive right of a
person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                   ARTICLE IX
                                   AMENDMENTS

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

                                    ARTICLE X
                                   DISSOLUTION

         If it should be deemed advisable in the judgment of the board of
directors of the corporation that the corporation should be dissolved, the
board, after the adoption of a resolution to that effect by a majority of the
whole board at any meeting called for that purpose, shall cause notice to be
mailed to each stockholder entitled to vote thereon of the adoption of the
resolution and of a meeting of stockholders to take action upon the resolution.

         At the meeting a vote shall be taken for and against the proposed
dissolution. If a majority of the outstanding stock of the corporation entitled
to vote thereon votes for the proposed dissolution, then a certificate stating
that the dissolution has been authorized in accordance with the provisions of
Section 275 of the General Corporation Law of Delaware and setting forth the
names and residences

                                     -19-
<PAGE>

of the directors and officers shall be executed, acknowledged, and filed and
shall become effective in accordance with Section 103 of the General
Corporation Law of Delaware. Upon such certificate's becoming effective in
accordance with Section 103 of the General Corporation Law of Delaware, the
corporation shall be dissolved.

         Whenever all the stockholders entitled to vote on a dissolution consent
in writing, either in person or by duly authorized attorney, to a dissolution,
no meeting of directors or stockholders shall be necessary. The consent shall be
filed and shall become effective in accordance with Section 103 of the General
Corporation Law of Delaware. Upon such consent's becoming effective in
accordance with Section 103 of the General Corporation Law of Delaware, the
corporation shall be dissolved. If the consent is signed by an attorney, then
the original power of attorney or a photocopy thereof shall be attached to and
filed with the consent. The consent filed with the Secretary of State shall have
attached to it the affidavit of the secretary or some other officer of the
corporation stating that the consent has been signed by or on behalf of all the
stockholders entitled to vote on a dissolution; in addition, there shall be
attached to the consent a certification by the secretary or some other officer
of the corporation setting forth the names and residences of the directors and
officers of the corporation.

                                   ARTICLE XI
                                    CUSTODIAN

         11.1     APPOINTMENT OF A CUSTODIAN IN CERTAIN CASES

         The Court of Chancery, upon application of any stockholder, may appoint
one or more persons to be custodians and, if the corporation is insolvent, to be
receivers, of and for the corporation when:

                  (a) at any meeting held for the election of directors the
stockholders are so divided that they have failed to elect successors to
directors whose terms have expired or would have expired upon qualification of
their successors; or

                  (b) the business of the corporation is suffering or is
threatened with irreparable injury because the directors are so divided
respecting the management of the affairs of the corporation that the required
vote for action by the board of directors cannot be obtained and the
stockholders are unable to terminate this division; or

                  (c) the corporation has abandoned its business and has failed
within a reasonable time to take steps to dissolve, liquidate or distribute its
assets.

         11.2     DUTIES OF CUSTODIAN

         The custodian shall have all the powers and title of a receiver
appointed under Section 291 of the General Corporation Law of Delaware, but the
authority of the custodian shall be to continue the business of the corporation
and not to liquidate its affairs and distribute its assets, except when the
Court of Chancery otherwise orders and except in cases arising under Sections
226(a)(3) or 352(a)(2) of the General Corporation Law of Delaware.
