         SECTION 1.1 The corporation shall maintain a registered office in the
State of Delaware as required by law. The corporation may also have such other
offices, either within or without the State of Delaware, as the business of the
corporation may require.

                                   ARTICLE II

                                  STOCKHOLDERS

         SECTION 2.1 ANNUAL MEETING. An annual meeting of the stockholders shall
be held commencing in 2000 on (a) the third Thursday of May of each year, if not
a legal holiday, and if a legal holiday, then on the next succeeding business
day, or (b) such other day as may be specified by the board of directors, for
the election of directors and for the transaction of such other business as may
come before the meeting.

         SECTION 2.2 SPECIAL MEETINGS. Special meetings of the stockholders may
be called by the President, the board of directors, or by a request in writing
from the holders of not less than 10% of the issued and outstanding voting stock
of the corporation. Within ten days after the receipt of such a written request,
the President or another officer designated by the President must send a notice
of meeting in accordance with section 2.4 hereof.

         SECTION 2.3 PLACE OF MEETING. The board of directors may designate any
place, either within or without the State of Delaware, as the place of meeting
for any annual meeting or for any special meeting called by the board of
directors. If a special meeting be called otherwise than by the board of
directors, the place of meeting must be in the county of New Castle, State of
Delaware.

         SECTION 2.4 NOTICE OF MEETING. Written notice stating the place, date
and hour of the meeting, the place where the stockholder list may be examined
prior to the meeting, if different from the place of the meeting, and, in the
case of a special meeting, the purpose or purposes for which the meeting is
called, shall be given in person or sent by mail or overnight express service
not less than ten nor more than sixty days before the date of the meeting, or in
the case of a merger or consolidation of the corporation requiring stockholder
approval or a sale, lease or exchange of all or substantially all of the
corporation's assets, not less than twenty nor more than sixty days before the
date of meeting, to each stockholder of record entitled to vote at

                                       2

<PAGE>

such meeting. If mailed, notice shall be deemed given when deposited in the
United States mail, postage prepaid, directed to the stockholder at his or her
address as it appears on the records of the corporation. If notice is given by
overnight express service, such notice shall be deemed given one day after
delivery to such express service. When a meeting is adjourned to another time or
place, 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, unless
the adjournment is for more than thirty days, or unless, after adjournment, a
new record date is fixed for the adjourned meeting, in either of which cases
notice of the adjourned meeting shall be given to each stockholder of record
entitled to vote at the meeting. Notice need not be given to any stockholder who
submits a written waiver of notice signed by such stockholder either before or
after any meeting. Attendance by a stockholder at a meeting of stockholders
shall constitute a waiver of notice of such meeting, except when the stockholder
attends the 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 need be specified in any waiver of
notice of such meeting.

         SECTION 2.5 FIXING OF RECORD DATE. (a) 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, 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, and
which record date shall not be more than sixty nor less than ten days before the
date of such meeting. If no record date is fixed by the board of directors, 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. 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 the
adjourned meeting.

         (b)      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, and which date shall not be more than ten days after the date upon
which the resolution fixing the record date is adopted by the board of
directors. If no record date has been fixed by the board of directors, 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 the Delaware General Corporation 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 an officer or agent of the
corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the corporation's registered office
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 the Delaware General Corporation Law, the
record date for determining stockholders entitled to consent to

                                       3

<PAGE>

corporate action in writing without a meeting shall be at the close of business
on the day on which the board of directors adopts the resolution taking such
prior action.

         (c)      In order that the corporation may determine 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 a record date, which record date
shall not precede the date upon which the resolution fixing the record date is
adopted, and which record date shall be not more than sixty days prior to such
action. If no record date is fixed, 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 resolution relating thereto.

         SECTION 2.6 VOTING LISTS. The officer who has charge of the stock
ledger of the corporation shall prepare and make, at least ten 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 number of shares registered in his name, which list, for a
period of ten days prior to such meeting, shall be kept on file either at a
place within the city where the meeting is to be held and 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, and shall be open to the examination of any
stockholder, for any purpose germane to the meeting, at any time during ordinary
business hours. Such 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 2.7 STOCK LEDGER. The stock ledger shall be the only evidence
as to who are the stockholders entitled to examine the stock ledger or the books
of the corporation, or to vote in person or by proxy at any meeting of
stockholders.

         SECTION 2.8 QUORUM. A majority of the outstanding shares of voting
stock of the corporation, represented in person or by proxy, shall constitute a
quorum at any meeting of stockholders; provided, however, that if less than a
majority of the outstanding shares of voting stock are represented at said
meeting, a majority of the shares of voting stock so represented may adjourn the
meeting. If a quorum is present, the affirmative vote of a majority of the
shares of voting stock represented at the meeting shall be the act of the
stockholders in all matters other than the election of directors, who shall be
elected by a plurality of the votes of the shares present in person or by proxy
and entitled to vote on the election of directors, unless the vote of a greater
number or voting by classes is required by the Delaware General Corporation Law,
the certificate of incorporation or these bylaws. At any adjourned meeting at
which a quorum shall be present, any business may be transacted which might have
been transacted at the original meeting. Requirements of notice at any adjourned
meeting are governed by Section 2.4 hereof. Withdrawal of stockholders from any
meeting shall not cause failure of a duly constituted quorum at that meeting.

         SECTION 2.9 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
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period. Every proxy must be

                                       4

<PAGE>

signed by the stockholder or his attorney-in-fact. A duly executed proxy shall
be irrevocable if it states that it is irrevocable, and if, and only as long as,
it is coupled with an interest sufficient in law to support an irrevocable
power. A proxy may be made irrevocable regardless of whether the interest with
which it is coupled is an interest in the stock itself or an interest in the
corporation generally.

         SECTION 2.10 VOTING OF STOCK. Subject to the provisions of the
certificate of incorporation, each stockholder shall at every meeting of the
stockholders be entitled to one vote for each share of the voting stock held by
such stockholder.

         SECTION 2.11 VOTING OF STOCK BY CERTAIN HOLDERS. Persons holding stock
in a fiduciary capacity shall be entitled to vote the shares so held. Persons
whose stock is pledged shall be entitled to vote, unless in the transfer by the
pledgor on the books of the corporation he has expressly empowered the pledgee
to vote thereon, in which case only the pledgee or his proxy may represent such
stock and vote thereon. Shares of its own stock belonging to the corporation or
to another corporation, if a majority of the shares entitled to vote in the
election of directors of such other corporation is held, directly or indirectly,
by the corporation, shall neither be entitled to vote nor counted for quorum
purposes, but shares of its stock held by the corporation in a fiduciary
capacity may be voted by it and counted for quorum purposes.

         SECTION 2.12 CONSENT OF STOCKHOLDERS. (a) Unless otherwise provided in
the certificate of incorporation, any action required to be taken at any annual
or special meeting of stockholders of the corporation, or any action which may
be taken at any annual or special meeting of 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, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted and shall be delivered to the corporation by
delivery to its principal place of business, or to an officer or agent of the
corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the corporation's registered office
in Delaware shall be by hand or by certified or registered mail, return receipt
requested.

         (b)      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 days of the
earliest dated consent delivered in the manner required by this section to the
corporation, written consents signed by a sufficient number of holders to take
such action are delivered to the corporation by delivery to its registered
office in Delaware, its principal place of business, or an officer or agent of
the corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the corporation's registered office
in Delaware shall be by hand or by certified or registered mail, return receipt
requested.

         (c)      Prompt notice of the taking of any corporate action without a
meeting by less than unanimous written consent shall be given to those
stockholders who have not consented thereto in writing.

         SECTION 2.13 VOTING BY BALLOT. Voting in any election of directors may,
if permitted by the certificate of incorporation, be by voice vote, and voting
on any other question shall be by voice vote unless, in each case, the presiding
officer shall order or any stockholder shall demand that voting be by ballot.

         SECTION 2.14 INSPECTORS. The board of directors, in advance of any
meeting, may, but need not, appoint one or more inspectors of election to act at
the meeting or any adjournment thereof. If an inspector or inspectors are not
appointed, the person presiding at the meeting may, or upon the request of any
stockholder shall, appoint one or more inspectors. In case any person who may be
appointed as an inspector fails to appear or act, the vacancy may be filled by
appointment made by the directors in advance of the meeting or at the meeting by
the person presiding thereat. Each inspector, if any, before entering upon the
discharge of his or her duties, shall take and sign an oath faithfully to
execute the duties of inspector at such meeting with strict impartiality and
according to the best of his ability. The inspectors, if any, shall determine
the number of shares of stock outstanding and the voting power of each, the
shares of stock represented at the meeting, the existence of a quorum, the
validity and effect of proxies, and shall receive votes, ballots or consents,
hear and determine all challenges and questions arising in connection with the
right to vote, count and tabulate all votes, ballots or consents, determine the
result, and do such acts as are proper to conduct the election or vote with
fairness to all stockholders. On request of the person presiding at the meeting,
the inspector or inspectors, if any, shall make a report in writing of any
challenge, question or matter determined by him, her or them and execute a
certificate of any fact found by him, her or them.

meeting of stockholders, and directors who are elected in the interim to fill
vacancies and newly created directorships, shall hold office until the next
annual meeting of stockholders and until their successors are elected and
qualified or until their earlier death, resignation or removal. In the interim
between annual meetings of stockholders or of special meetings of

                                       6

<PAGE>

stockholders called for the election of directors and/or for the removal of one
or more directors and for the filling of any vacancy in that connection, newly
created directorships and any vacancies in the board of directors, including
vacancies resulting from the removal of directors, may be filled by the vote of
a majority of the remaining directors then in office, although less than a
quorum, or by the sole remaining director.

express service so addressed, with postage thereon prepaid. Notice need not be
given to any director who submits a written waiver of notice signed by him
either before or after any meeting. The attendance of a director at any meeting
shall constitute a waiver of notice of such meeting, except where a director
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 board of directors need be specified
in the notice or waiver of such meeting.

         SECTION 3.7 QUORUM. A majority of the number of directors fixed by or
determined in accordance with these bylaws (or of the members of any committee

quorum at a meeting of the board of directors or of a committee thereof

         SECTION 3.8 MANNER OF ACTING. The vote of a majority of the directors

to be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting if all the members of the board or committee, as
the case may be, consent

                                       7

Delaware General Corporation Law regarding the payment of dividends, any
director who may have been absent when the same was done, or who may have
dissented from the act or resolution by which the same was done, may exonerate
himself from such liability by causing his dissent to be entered on the books
containing the minutes of the proceedings of the directors at the time the same
was done, or immediately after he has notice of the same.

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,
to the extent permitted under the Delaware General Corporation Law.

         SECTION 3.15 RETIREMENT AGE. No person shall be nominated for election

of the board of directors. Each officer shall hold office until his successor is

Any officer may resign at any time upon written notice to the corporation.
Election of an officer shall not of itself create contract rights.

         SECTION 4.3 REMOVAL. Any officer elected by the board of directors may
be removed by the board of directors whenever in its judgment the best interests
of the corporation would be served thereby, but such removal shall be without
prejudice to the contract rights, if any, of the person so removed.

same effect as if he or she were such officer, transfer agent or registrar at
the date of issue. The name of the person to whom the shares represented thereby
are issued, with the number of shares and date of issue, shall be entered on the
books of the corporation. All certificates surrendered to the corporation for
transfer shall be canceled and no new certificates shall be issued until the
former certificate for a like number of shares shall have been surrendered and
canceled, except that in case of a lost, destroyed or mutilated certificate, a
new certificate may be issued therefor upon such terms, indemnity and surety to
the corporation as the board of directors may prescribe.

         SECTION 6.2 TRANSFER OF SHARES OF STOCK. Transfers of shares of stock
of the corporation shall be made on the books of the corporation by the holder
of record thereof or by his or her legal representative, who shall furnish
proper evidence of authority to transfer, or by his or her attorney thereunto
authorized by power of attorney duly executed and filed with the Secretary of
the corporation, and on surrender for cancellation of the certificate for such
shares. The person in whose name shares of stock stand on the books of the
corporation shall be deemed the owner thereof for all purposes as regards the
corporation.

         SECTION 6.3 TRANSFER AGENTS AND REGISTRARS. The board of directors may
appoint one or more transfer agents or assistant transfer agents and one or more
registrars of transfers, and may require all certificates for shares of stock of

                                 INDEMNIFICATION

         SECTION 7.1 DIRECTORS AND OFFICERS. (a) The corporation shall indemnify
any person who was or is a party or is threatened to be made party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he or she is or was a
director or officer of the corporation, or is or was serving at the request of
the corporation as a director, manager or officer of another corporation,
partnership, joint venture, trust, limited liability company or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding if he or she acted in good faith
and in a manner he or she reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he or she reasonably believed to be in or not
opposed to the best interests of the corporation, and, with

                                       11

respect to any criminal action or proceeding, had reasonable cause to believe
that his or her conduct was unlawful.

         (b)      The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director or
officer of the corporation, or is or was serving at the request of the
corporation as a director, manager or officer of another corporation,
partnership, joint venture, trust, limited liability company or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him or her in connection with the defense or settlement of such action or suit
if he or she acted in good faith and in a manner he or she reasonably believed
to be in or not opposed to the best interests of the corporation, and except
that no indemnification shall be made in respect of any claim, issue or matter
as to which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery of the State of
Delaware or the court in which action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery of the State of Delaware
or such other court shall deem proper.

         (c)      To the extent that any person referred to in paragraphs (a)
and (b) of this Section 7.1 has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to therein or in defense of
any claim, issue or matter therein, he or she shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection therewith.

         (d)      Any indemnification under paragraphs (a) and (b) of this
section 7.1 (unless ordered by a court) shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification of the
director or officer is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in paragraphs (a) and (b) of this
Section 7.1. Such determination shall be made (i) by the board of directors by a
majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding or (ii) if such quorum is not obtainable, or, even if
obtainable a quorum of disinterested directors so directs, by independent legal
counsel in a written opinion, or (iii) by the stockholders.

         (e)      Expenses incurred in defending a civil or criminal action,
suit or proceeding may be paid by the corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of the director or officer to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by the
corporation as provided in this section 7.1.

         (f)      The indemnification and advancement of expenses provided by or
granted pursuant to this section 7.1 shall not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may be
entitled under any statute, bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his or her official
capacity and as to action in another capacity while holding such office.

         (g)      The corporation shall have power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, manager, officer, employee or agent of another corporation,
partnership, joint venture, trust, limited liability company or other
enterprise, against any liability asserted against him and incurred by him in
any such capacity, or arising out of his status as such, whether or not the
corporation would have the power to indemnify him against such liability under
the provisions of this section 7.1.

         (h)      For purposes of this section 7.1, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the corporation"
shall include any service as a director, officer, employee or agent of the
corporation which imposes duties on, or involves services by, such director,
officer, employee, or agent with respect to an employee benefit plan, its
participants or beneficiaries; and a person who acted in good faith and in a
manner he or she reasonably believed to be in the interest of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the corporation" as referred to in
this section.

         (i)      The indemnification and advancement of expenses provided by,
or granted pursuant to, this section shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

         (j)      Unless otherwise determined by the board of directors,
references in this section to "the corporation" shall include in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
manager, officer, employee or agent of another corporation, partnership, joint
venture, trust, limited liability company or other enterprise, shall stand in
the same position under this section with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

         SECTION 7.2 EMPLOYEES AND AGENTS. The board of directors may, by
resolution, extend the indemnification provisions of the foregoing section 7.1
to any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding by reason of the
fact that he or she is or was an employee or agent of the corporation, or is or
was serving at the request of the corporation as an employee or agent of another
corporation, partnership, joint venture, trust, limited liability company or
other enterprise.

or on such other date as the board of directors may from time to time determine
by resolution.

                                   ARTICLE IX

                                    DIVIDENDS

                                WAIVER OF NOTICE

         SECTION 11.1 Whenever any notice whatever is required to be given under
any provision of these bylaws or of the certificate of incorporation or of the
Delaware General Corporation Law, 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 transactions 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 or directors or of a committee of
the board of directors need be specified in any written waiver of notice.

                                   ARTICLE XII
