                                  STOCKHOLDERS

         Section 1.        Annual Meeting. An annual meeting of the
stockholders, for the election of directors to succeed those whose terms expire
and for the transaction of such other business as may properly come before the
meeting, shall be held at such place, on such date, and at such time as the
Board of Directors shall each year fix, which date shall be within thirteen (13)
months of the last annual meeting of stockholders or, if no such meeting has
been held, the date of incorporation.

         Section 2.        Special Meetings. Special meetings of the
stockholders, for any purpose or purposes prescribed in the notice of the
meeting, may be called by the Board of Directors or the chief executive officer
and shall be held at such place, on such date, and at such time as they or he or
she shall fix.

         Section 3.        Notice of Meetings. Written notice of the place,
date, and time of all meetings of the stockholders shall be given, not less than
ten (10) nor more than sixty (60) days before the date on which the meeting is
to be held, to each stockholder entitled to vote at such meeting, except as
otherwise provided herein or required by law (meaning, here and hereinafter, as
required from time to time by the Delaware General Corporation Law or the
Certificate of Incorporation of the Corporation).

         When a meeting is adjourned to another place, date or time, written
notice need not be given of the adjourned meeting if the place, date and time
thereof are announced at the meeting at which the adjournment is taken;
provided, however, that if the date of any adjourned meeting is more than thirty
(30) days after the date for which the meeting was originally noticed, or if a
new record date is fixed for the adjourned meeting, written notice of the place,
date, and time of the adjourned meeting shall be given in conformity herewith.
At any adjourned meeting, any business may be transacted which might have been
transacted at the original meeting.

         Section 4.        Quorum. At any meeting of the stockholders, the
holders of a majority of all of the shares of the stock entitled to vote at the
meeting, present in person or by proxy, shall constitute a quorum for all
purposes, unless or except to the extent that the presence of a larger number
may be required by law. Where a separate vote by a class or classes is required,
a majority of the shares of such class or classes present in person or
represented by proxy shall constitute a quorum entitled to take action with
respect to that vote on that matter.

         If a quorum shall fail to attend any meeting, the chairman of the
meeting or the holders of a majority of the shares of stock entitled to vote who
are present, in person or by proxy, may adjourn the meeting to another place,
date, or time.

         Section 5.        Organization. Such person as the Board of Directors
may have designated or, in the absence of such a person, the chief executive
officer of the Corporation or, in his or her absence, such person as may be
chosen by the holders of a majority of the shares entitled to vote



who are present, in person or by proxy, shall call to order any meeting of the
stockholders and act as chairman of the meeting. In the absence of the Secretary
of the Corporation, the secretary of the meeting shall be such person as the
chairman appoints.

         Section 6.        Conduct of Business. The chairman of any meeting of
stockholders shall determine the order of business and the procedure at the
meeting, including such regulation of the manner of voting and the conduct of
discussion as seem to him or her in order. The date and time of the opening and
closing of the polls for each matter upon which the stockholders will vote at
the meeting shall be announced at the meeting.

         Section 7.        Proxies and Voting. At any meeting of the
stockholders, every stockholder entitled to vote may vote in person or by proxy
authorized by an instrument in writing or by a transmission permitted by law
filed in accordance with the procedure established for the meeting. Any copy,
facsimile telecommunication or other reliable reproduction of the writing or
transmission created pursuant to this paragraph may be substituted or used in
lieu of the original writing or transmission for any and all purposes for which
the original writing or transmission could be used, provided that such copy,
facsimile telecommunication or other reproduction shall be a complete
reproduction of the entire original writing or transmission.

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

         All elections shall be determined by a plurality of the votes cast, and
except as otherwise required by law, all other matters shall be determined by a
majority of the votes cast affirmatively or negatively.

         Section 8.        Stock List. A complete list of stockholders entitled
to vote at any meeting of stockholders, arranged in alphabetical order for each
class of stock and showing the address of each such stockholder and the number
of shares registered in his or her name, shall be open to the examination of any
such 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.

                                      -2-



         The stock list shall also be kept at the place of the meeting during
the whole time thereof and shall be open to the examination of any such
stockholder who is present. This list shall presumptively determine the identity
of the stockholders entitled to vote at the meeting and the number of shares
held by each of them.

         Section 9.        Consent of Stockholders in Lieu of Meeting. 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 the stockholders, may be taken without a meeting, without prior
notice and without a vote, if a consent or consents 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 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 made by hand or by certified or
registered mail, return receipt requested.

         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 date the earliest dated consent is delivered to the Corporation, a written
consent or consents signed by a sufficient number of holders to take action are
delivered to the Corporation in the manner prescribed in the first paragraph of
this Section.

                                   ARTICLE II

         Section 1.        Number and Term of Office. The number of directors
who shall constitute the whole Board shall be such number as the Board of
Directors shall from time to time have designated, except that in the absence of
any such designation, such number shall be four (4). Each director shall be
elected for a term of one year and until his or her successor is elected and
qualified, except as otherwise provided herein or required by law.

         Whenever the authorized number of directors is increased between annual
meetings of the stockholders, a majority of the directors then in office shall
have the power to elect such new directors for the balance of a term and until
their successors are elected and qualified. Any decrease in the authorized
number of directors shall not become effective until the expiration of the term
of the directors then in office unless, at the time of such decrease, there
shall be vacancies on the board which are being eliminated by the decrease.

         Section 2.        Vacancies. If the office of any director becomes
vacant by reason of death, resignation, disqualification, removal or other
cause, a majority of the directors remaining in office, although less than a
quorum, may elect a successor for the unexpired term and until his or her
successor is elected and qualified.

         Section 3.        Regular Meetings. Regular meetings of the Board of
Directors shall be held at such place or places, on such date or dates, and at
such time or times as shall have been

                                      -3-



established by the Board of Directors and publicized among all directors. A
notice of each regular meeting shall not be required.

         Section 4.        Special Meetings. Special meetings of the Board of
Directors may be called by one-third (1/3) of the directors then in office
(rounded up to the nearest whole number) or by the chief executive officer and
shall be held at such place, on such date, and at such time as they or he or she
shall fix. Notice of the place, date, and time of each such special meeting
shall be given each director by whom it is not waived by mailing written notice
not less than five (5) days before the meeting or by telegraphing or telexing or
by facsimile transmission of the same not less than twenty-four (24) hours

present may adjourn the meeting to another place, date, or time, without further
notice or waiver thereof.

         Section 6.        Participation in Meetings By Conference Telephone.
Members of the Board of Directors, or of any committee thereof, may participate
in a meeting of such Board or committee by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other and such participation shall constitute presence
in person at such meeting.

         Section 7.        Conduct of Business. At any meeting of the Board of
Directors, business shall be transacted in such order and manner as the Board
may from time to time determine, and all matters shall be determined by the vote
of a majority of the directors present, except as otherwise provided herein or
required by law. Action may be taken by the Board of Directors without a meeting
if all members thereof consent thereto in writing, and the writing or writings
are filed with the minutes of proceedings of the Board of Directors.

         Section 8.        Powers. The Board of Directors may, except as
otherwise required by law, exercise all such powers and do all such acts and
things as may be exercised or done by the Corporation, including, without
limiting the generality of the foregoing, the unqualified power:

                (1)        To declare dividends from time to time in accordance
with law;

                (2)        To purchase or otherwise acquire any property, rights
or privileges on such terms as it shall determine;

                (3)        To authorize the creation, making and issuance, in

                (7)        To adopt from time to time such insurance,
retirement, and other benefit plans for directors, officers, employees and

                (8)        To adopt from time to time regulations, not
inconsistent with these By-laws, for the management of the Corporation's
business and affairs.

         Section 9.        Compensation of Directors. Directors, as such, may
receive, pursuant to resolution of the Board of Directors, fixed fees and other
compensation for their services as directors, including, without limitation,
their services as members of committees of the Board of Directors.

                                  ARTICLE III

                                   COMMITTEES

         Section 1.        Committees of the Board of Directors. The Board of
Directors, by a vote of a majority of the whole Board, may from time to time
designate committees of the Board, with such lawfully delegable powers and
duties as it thereby confers, to serve at the pleasure of the Board and shall,
for those committees and any others provided for herein, elect a director or
directors to serve as the member or members, designating, if it desires, other
directors as alternate members who may replace any absent or disqualified member
at any meeting of the committee. Any committee so designated may exercise the
power and authority of the Board of Directors 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 Delaware General Corporation Law if the
resolution which designates the committee or a supplemental resolution of the
Board of Directors shall so provide. In the absence or disqualification of any
member of any committee and any alternate member in his or her place, the member
or members of the committee present at the meeting and not disqualified from
voting, whether or not he or she or they constitute a quorum, may by unanimous
vote appoint another member of the Board of Directors to act at the meeting in
the place of the absent or disqualified member.

         Section 2.        Conduct of Business. Each committee may determine the
procedural rules for meeting and conducting its business and shall act in
accordance therewith, except as otherwise provided herein or required by law.
Adequate provision shall be made for notice to members of all meetings;
one-third (1/3) of the members shall constitute a quorum unless the committee
shall consist of one (1) or two (2) members, in which event one (1) member shall
constitute a quorum; and all matters shall be determined by a majority vote of
the members present. Action may be taken by any committee without a meeting if
all members thereof consent thereto in writing, and the writing or writings are
filed with the minutes of the proceedings of such committee.

otherwise to exercise any and all rights and powers which this Corporation may

                                   ARTICLE V

                                      STOCK

         Section 1.        Certificates of Stock. Each stockholder shall be
entitled to a certificate signed by, or in the name of the Corporation by, the
President or a Vice President, and by the Secretary or an Assistant Secretary,
or the Treasurer or an Assistant Treasurer, certifying the number of shares

only upon the transfer books of the Corporation kept at an office of the
Corporation or by transfer agents designated to transfer shares of the stock of
the Corporation. Except where a certificate is issued in accordance with Section
4 of Article V of these By-laws, an outstanding certificate for the number of
shares involved shall be surrendered for cancellation before a new certificate
is issued therefor.

         Section 3.        Record Date. In order that the Corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
stockholders, or to receive payment of any dividend or other distribution or
allotment of any rights or to exercise any rights in respect of any change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date on which the resolution fixing the record date is adopted and
which record date shall not be more than sixty (60) nor less than ten (10) days
before the date of any meeting of stockholders, nor more than sixty (60) days
prior to the time for such other action as hereinbefore described; provided,
however, that 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, and, for
determining stockholders entitled to receive payment of any dividend or other
distribution or allotment of rights or to exercise any rights of change,
conversion or exchange of stock or for any other purpose, the record date shall
be at the close of business on the day on which the Board of Directors adopts a
resolution relating thereto.

         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.

         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 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 be not more than ten (10) days after the date upon which
the resolution fixing the record date is adopted. If no record date has been
fixed by the Board of Directors and no prior action by the Board of Directors is
required by the Delaware General Corporation Law, the record date shall be the
first date on which a signed written

                                      -7-



consent setting forth the action taken or proposed to be taken is delivered to
the Corporation in the manner prescribed by Article I, Section 9 hereof. 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 with
respect to the proposed action by written consent of the stockholders, the
record date for determining stockholders entitled to consent to corporate action
in writing shall be at the close of business on the day on which the Board of
Directors adopts the resolution taking such prior action.

of the loss, theft or destruction of any certificate of stock, another may be
issued in its place pursuant to such regulations as the Board of Directors may
establish concerning proof of such loss, theft or destruction and concerning the
giving of a satisfactory bond or bonds of indemnity.

         Section 5.        Regulations. The issue, transfer, conversion and
registration of certificates of stock shall be governed by such other
regulations as the Board of Directors may establish.

herein or required by law, all notices required to be given to any stockholder,
director, officer, employee or agent shall be in writing and may in every
instance be effectively given by hand delivery to the recipient thereof, by
depositing such notice in the mails, postage paid, or by sending such notice by
prepaid telegram or mailgram. Any such notice shall be addressed to such
stockholder, director, officer, employee or agent at his or her last known
address as the same appears on the books of the Corporation. The time when such
notice is received, if hand delivered, or dispatched, if delivered through the
mails or by telegram or mailgram, shall be the time of the giving of the notice.

         Section 2.        Waivers. A written waiver of any notice, signed by a
stockholder, director, officer, employee or agent, whether before or after the
time of the event for which notice is to be given, shall be deemed equivalent to
the notice required to be given to such stockholder, director, officer, employee
or agent. Neither the business nor the purpose of any meeting need be specified
in such a waiver.

                                  ARTICLE VII

                                  MISCELLANEOUS

         Section 1.        Facsimile Signatures. In addition to the provisions
for use of facsimile signatures elsewhere specifically authorized in these
By-laws, facsimile signatures of any officer or officers of the Corporation may
be used whenever and as authorized by the Board of Directors or a committee
thereof.

         Section 2.        Corporate Seal. The Board of Directors may provide a
suitable seal, containing the name of the Corporation, which seal shall be in
the charge of the Secretary. If and when so directed by the Board of Directors
or a committee thereof, duplicates of the seal may be kept and used by the
Treasurer or by an Assistant Secretary or Assistant Treasurer.

                                      -8-



         Section 3.        Reliance upon Books, Reports and Records. Each
director, each member of any committee designated by the Board of Directors, and
each officer of the Corporation shall, in the performance of his or her duties,
be fully protected in relying in good faith upon the books of account or other
records of the Corporation and upon such information, opinions, reports or
statements presented to the Corporation by any of its officers or employees, or
committees of the Board of Directors so designated, or by any other person as to
matters which such director or committee member reasonably believes are within
such other person's professional or expert competence and who has been selected
with reasonable care by or on behalf of the Corporation.

         Section 4.        Fiscal Year. The fiscal year of the Corporation shall
be as fixed by the Board of Directors.

         Section 5.        Time Periods. In applying any provision of these
By-laws which requires that an act be done or not be done a specified number of
days prior to an event or that an act be done during a period of a specified
number of days prior to an event, calendar days shall be used, the day of the
doing of the act shall be excluded, and the day of the event shall be included.

                                  ARTICLE VIII

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 1.        Right to Indemnification. Each person who was or is
made a party or is threatened to be made a party to or is otherwise involved in
any action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that he or she
is or was a director or an officer of the Corporation or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to an employee benefit plan
(hereinafter an "indemnitee"), whether the basis of such proceeding is alleged
action in an official capacity as a director, officer, employee or agent or in
any other capacity while serving as a director, officer, employee or agent,
shall be indemnified and held harmless by the Corporation to the fullest extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits the Corporation to provide broader indemnification
rights than such law permitted the Corporation to provide prior to such
amendment), against all expense, liability and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid in
settlement) reasonably incurred or suffered by such indemnitee in connection
therewith; provided, however, that, except as provided in Section 3 of this
ARTICLE VIII with respect to proceedings to enforce rights to indemnification,
the Corporation shall indemnify any such indemnitee in connection with a
proceeding (or part thereof) initiated by such indemnitee only if such
proceeding (or part thereof) was authorized by the Board of Directors of the
Corporation.

         Section 2.        Right to Advancement of Expenses. The right to
indemnification conferred in Section 1 of this ARTICLE VIII shall include the
right to be paid by the Corporation the expenses (including attorney's fees)
incurred in defending any such proceeding in advance of its final disposition
(hereinafter an "advancement of expenses"); provided, however, that, if the
Delaware General Corporation Law requires, an advancement of expenses incurred
by an indemnitee in his or her capacity as a director or officer (and not in any
other

                                      -9-



capacity in which service was or is rendered by such indemnitee, including,
without limitation, service to an employee benefit plan) shall be made only upon
delivery to the Corporation of an undertaking (hereinafter an "undertaking"), by
or on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
indemnitee is not entitled to be indemnified for such expenses under this
Section 2 or otherwise. The rights to indemnification and to the advancement of
expenses conferred in Sections 1 and 2 of this ARTICLE VIII shall be contract
rights and such rights shall continue as to an indemnitee who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
indemnitee's heirs, executors and administrators.

         Section 3.        Right of Indemnitee to Bring Suit. If a claim under
Section 1 or 2 of this ARTICLE VIII is not paid in full by the Corporation
within sixty (60) days after a written claim has been received by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty (20) days, the indemnitee may
at any time thereafter bring suit against the Corporation to recover the unpaid
amount of the claim. If successful in whole or in part in any such suit, or in a
suit brought by the Corporation to recover an advancement of expenses pursuant
to the terms of an undertaking, the indemnitee shall be entitled to be paid also
the expense of prosecuting or defending such suit. In (i) any suit brought by
the indemnitee to enforce a right to indemnification hereunder (but not in a
suit brought by the indemnitee to enforce a right to an advancement of expenses)
it shall be a defense that, and (ii) in any suit brought by the Corporation to
recover an advancement of expenses pursuant to the terms of an undertaking, the
Corporation shall be entitled to recover such expenses upon a final adjudication
that, the indemnitee has not met any applicable standard for indemnification set
forth in the Delaware General Corporation Law. Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit. In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or brought by the Corporation to recover an advancement of expenses pursuant to
the terms of an undertaking, the burden of proving that the indemnitee is not
entitled to be indemnified, or to such advancement of expenses, under this
ARTICLE VIII or otherwise shall be on the Corporation.

         Section 4.        Non-Exclusivity of Rights. The rights to
indemnification and to the advancement of expenses conferred in this ARTICLE
VIII shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, the Corporation's Certificate of
Incorporation, By-laws, agreement, vote of stockholders or disinterested
directors or otherwise.

         Section 5.        Insurance. The Corporation may maintain insurance, at
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another

                                      -10-



corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the Corporation would have the power
to indemnify such person against such expense, liability or loss under the
Delaware General Corporation Law.

         Section 6.        Indemnification of Employees and Agents of the
Corporation. The Corporation may, to the extent authorized from time to time by
the Board of Directors, grant rights to indemnification and to the advancement
of expenses to any employee or agent of the Corporation to the fullest extent of
the provisions of this Article with respect to the indemnification and
advancement of expenses of directors and officers of the Corporation.

                                   ARTICLE IX

                                   AMENDMENTS

         These By-laws may be amended or repealed by the Board of Directors at
any meeting or by the stockholders at any meeting.
