                       ARTICLE II. STOCKHOLDERS' MEETINGS.

Section 1. Annual Meetings.

(a)      The annual meeting of the stockholders of the Corporation, commencing
         with the year 2002 shall be held at the principal office of the
         Corporation in the State of Delaware or at any other place within or
         without the State of Delaware as may be determined by the Board of
         Directors and as may be designated in the notice of that meeting.

         The meeting shall be held on the first Monday in November of each year.
         If that day is a legal holiday, the meeting shall be held on the next
         succeeding day not a legal holiday. The business to be transacted at
         the meeting shall be the election of directors and such other business
         as properly brought before the meeting.

(b)      If the election of directors shall not be held on the day herein
         designated for any annual meeting, or at any adjournment of that
         meeting, the Board of Directors shall call a special meeting of the
         stockholders as soon as possible thereafter.

         At this meeting the election of directors shall take place, and the
         election and any other business transacted shall have the same force
         and effect as at an annual meeting duly called and held.

(c)      No change in the time or place for a meeting for the election of
         directors shall be made within 20 days preceding the day on which the
         election is to be held. Written notice of any change shall be given
         each stockholder at least 20 days before the election is held, either
         in person or by letter mailed to the stockholder at the address last
         shown on the books of the Corporation.

(d)      In the event the annual meeting is not held at the time prescribed in
         Article II, Section I(a) above, and if the Board of Directors shall not
         call a special meeting as prescribed in Article II, Section l(b) above
         within three months after the date prescribed for the annual meeting,
         then any stockholder may call that meeting, and at that meeting the
         stockholders may elect the directors and transact other business with
         the same force and effect as at an annual meeting duly called and held.

                                       1



Section 2. Special Meetings.

Special meetings of the stockholders may be called by the President or by the
holders of at least thirty three percent (33%) of the stock entitled to vote at
that meeting. At any time, upon the written request of any person or persons
entitled to call a special meeting, it shall be the duty of the Secretary to
send out notices of the meeting, to be held within or without the State of
Delaware and at such time, but not less than 10 days nor more than 60 days after
receipt of the request, as may be fixed by the Board of Directors. If the Board
of Directors fails to fix a time or place, the meeting shall be held at the
principal office of the Corporation at a time as shall be fixed by the Secretary
within the above limits.

Section 3. Notice and Purpose of Meetings; Waiver.

Each stockholder of record entitled to vote at any meeting shall be given in
person, or by mail, or by prepaid telegram, written or printed notice of the
purpose or purposes, and the time and place within or outside the State of
Delaware of every meeting of stockholders. This notice shall be delivered not
less than 20 days nor more than 45 days before the meeting. If mailed or
telegraphed, it should be directed to the stockholder at the address last shown
on the books of the Corporation. No publication of the notice of meeting shall
be required. A stockholder may waive the notice of meeting by attendance, either
in person or by proxy, at the meeting, or by so stating in writing, either
before or after the meeting. Attendance at a meeting for the express purpose of
objecting that the meeting was not lawfully called or convened shall not,
however, constitute a waiver of notice. Except where otherwise required by law,
notice need not be given of any adjourned meeting of the stockholders.

Section 4. Quorum.

Except as otherwise provided by law, a quorum at all meetings of stockholders
shall consist of the holders of record of a majority of the shares entitled to
vote present in person or by proxy.

Section 5. Closing of Transfer Books; Record Date.

(a)      In order to determine the holders of record of the Corporation's stock
         who are entitled to notice of meetings, to vote at a meeting or its
         adjournment, to receive payment of any dividend, or to make a
         determination of the stockholders of record for any other proper
         purpose, the Board of Directors of the Corporation may order that the
         Stock Transfer Books be closed for a period not to exceed sixty days.
         If the purpose of this closing is to determine who is entitled to
         notice of a meeting and to vote at such meeting, the Stock Transfer
         Books shall be closed for at least thirty days preceding such meeting.

(b)      In lieu of closing the Stock Transfer Books, the Board of Directors may
         fix a date as the record date for the determination of stockholders.
         This date shall be no more than sixty days prior to the date of the
         action which requires the determination, nor, in the case of a
         stockholders' meeting, shall it be less than thirty days in advance of
         such meeting.

                                       2



(c)      If the Stock Transfer Books are not closed and no record date is fixed
         for the determination of the stockholders of record, the date of which
         notice of the meeting is mailed, or on which the resolution of the
         Board of Directors declaring a dividend is adopted, as the case may be,
         shall be the record date for the determination of stockholders.

(d)      When a determination of stockholders entitled to vote at any meeting
         has been made as provided in this section, this determination shall
         apply to any adjournment of the meeting, except when the determination
         has been made by the closing of the Stock Transfer Books and the stated
         period of closing has expired.

Section 6. Presiding Officer; Order of Business

(a)      Meetings of the stockholders shall be presided over by the Chairman of
         the Board, or, if he or she is not present, by the Chief Executive
         Officer, or if not present, by the President, or if he or she is not
         present, by a Vice-President, or if neither the Chairman of the Board
         nor the Chief Executive Officer nor the President nor a Vice-President
         is present, by a chairman to be chosen by a majority of the
         stockholders entitled to vote at the meeting who are present in person
         or by proxy. The Secretary of the Corporation, or, in her or his
         absence, an Assistant Secretary, shall act as secretary of every
         meeting, but if neither the Secretary nor an Assistant Secretary is
         present, the stockholders present at the meeting shall choose any
         person present to act as secretary of the meeting.

(b)      The order of business shall be as follows:

         1.       Call of meeting to order.

Section 7. Voting.

(a)      Except in the election of directors, at which time the stockholders
         shall be entitled to cumulate their votes, and except as otherwise
         provided in the Articles of Incorporation, the Bylaws, or the laws of
         the State of Delaware at every meeting of the stockholders, each
         stockholder of the Corporation entitled to vote at the meeting shall
         have, as to each matter submitted to a vote, one vote in person or by
         proxy for each share of stock having voting rights registered in his or
         her name on the books of the Corporation. A stockholder may vote his or
         her shares through a proxy appointed by a written instrument signed by
         the stockholder or by a duly authorized attorney-in-fact and delivered
         to the secretary of the meeting. No proxy shall be valid after three
         months from the date of its execution unless a longer period is
         expressly provided.

                                       3



(b)      A majority vote of those shares entitled to vote and represented at the
         meeting, a quorum being present, shall be the act of the meeting except
         that in electing directors a plurality of the votes cast shall elect.

(c)      At all elections of directors, the voting shall be by ballot.

Section 8. List of Stockholders.

(a)      A complete list of the stockholders of the Corporation entitled to vote
         at the ensuing meeting, arranged in alphabetical order, and showing the
         address of, and number of shares owned by, each stockholder shall be
         prepared by the Secretary, or other officer of the Corporation having
         charge of the Stock Transfer Books. This list shall be kept on file for
         a period of at least ten days prior to the meeting at the principal
         office of the Corporation and shall be subject to inspection during the
         usual business hours of such period by any stockholder. This list shall
         also be available at the meeting and shall be open to inspection by any
         stockholder at any time during the meeting.

(b)      The original Stock Transfer Books shall be prima facie evidence as to
         who are the stockholders entitled to examine the list or to vote at any
         meeting of the stockholders.

(c)      Failure to comply with the requirements of this section shall not
         affect the validity of any action taken at any meetings of the
         stockholders.

                             ARTICLE III. DIRECTORS.

Section 1.  Number, Qualification, Term, Quorum, and Vacancies.

(a)      The property, affairs and business of the Corporation shall be managed
         by a Board of Directors of two persons. Except as provided, directors
         shall be elected at the annual meeting of the stockholders and each
         director shall serve for one year and/or until his or her successor
         shall be elected and qualify.

(b)      The number of directors may be increased or decreased from time to time
         by an amendment to these Bylaws. Any increased number of directors
         shall be elected by the stockholders at the next regular annual meeting
         or at a special meeting called for that purpose. The number of
         directors shall never be less than one.

(c)      Directors need not be stockholders of the Corporation.

(d)      A majority of the directors in office shall be necessary to constitute
         a quorum for the transaction of business. If, at any meeting of the
         Board of Directors, there shall be less than a quorum present, a
         majority of those present may adjourn the meeting, without further
         notice, from time to time until a quorum shall have been obtained. In
         case there are vacancies on the Board of Directors, other than
         vacancies created by the removal of a director or directors by the
         stockholders or by an increase in the number of directors, the
         remaining directors, although less than a quorum, may by a majority
         vote elect a successor or successors for the unexpired term or terms.

                                       4



Section 2. Meetings.

Meetings of the Board of Directors may be held either within or without the
State of Delaware. Meetings of the Board of Directors shall be held at those
times as are fixed from time to time by resolution of the Board. Special
meetings may be held at any time upon call of the Chairman of the Board, the
Chief Executive Officer, the President, or a Vice-President, or a majority of
directors, upon written or telegraphic notice deposited in the U.S. mail or
delivered to the telegraph company at least thirty days prior to the day of the
meetings. A meeting of the Board of Directors may be held without notice
immediately following the annual meeting of the stockholders. Notice need not be
given of regular meetings of the Board of Directors held at times fixed by
resolution of the Board of Directors nor need notice be given of adjourned
meetings. Meetings may be held at any time without notice if all the directors
are present or if, before the meeting, those not present waive such notice in
writing. Notice of a meeting of the Board of Directors need not state the
purpose of, nor the business to be transacted at, any meeting.

Section 3. Removal.

(a)      At any meeting of the stockholders, any director or directors may be
         removed from office, without assignment of any reason, by a majority
         vote of the shares or class of shares, as the case may be, which
         elected the director or directors to be removed, provided, however,
         that if less than all the directors are to be removed, no individual
         director shall be removed if the number of votes cast against her or
         his removal would be sufficient, if cumulatively voted at an election
         of the entire board, to elect one or more directors.

(b)      When any director or directors are removed, new directors may be
         elected at the same meeting of the stockholders for the unexpired term
         of the director or directors removed. If the stockholders fail to elect
         persons to fill the unexpired term or terms of the director or
         directors removed, these unexpired terms shall be considered vacancies
         on the board to be filled by the remaining directors.

Section 4. Indemnification.

(a)      The Corporation shall indemnify each of its directors, officers, and
         employees whether or not then in service as such (and his or her
         executor, administrator and heirs), against all reasonable expenses
         actually and necessarily incurred by him or her in connection with the
         defense of any litigation to which the individual may have been made a
         party because he or she is or was a director, officer or employee of
         the Corporation. The individual shall have no right to reimbursement,
         however, in relation to matters as to which he or she has been adjudged
         liable to the Corporation for negligence or misconduct in the
         performance of his or her duties, or was derelict in the performance of
         his or her duty as director, officer or employee by reason of willful
         misconduct, bad faith, gross negligence or reckless disregard of the
         duties of his or her office or employment. The right to indemnity for
         expenses shall also apply to the expenses of suits which are
         compromised or settled if the court having jurisdiction of the matter
         shall approve such settlement.

                                       5



(b)      The foregoing right of indemnification shall be in addition to, and not
         exclusive of, all other rights to that which such director, officer or
         employee may be entitled.

Section 5. Compensation.

Directors, and members of any committee of the Board of Directors, shall be
entitled to any reasonable compensation for their services as directors and
members of any committee as shall be fixed from time to time by resolution of
the Board of Directors, and shall also be entitled to reimbursement for any
reasonable expense incurred in attending those meetings. The compensation of
directors may be on any basis as determined in the resolution of the Board of
Directors. Any director receiving compensation under these provisions shall not
be barred from serving the Corporation in any other capacity and receiving
reasonable compensation for such other services.

Section 6. Committees.

(a)      The Board of Directors, by a resolution or resolutions adopted by a
         majority of the members of the whole Board, may appoint an Executive
         Committee, an Audit Committee, and any other committees as it may deem
         appropriate. Each committee shall consist of at least (insert number of
         directors required for committee) of members of the Board of Directors.
         Each committee shall have and may exercise any and all powers as are
         conferred or authorized by the resolution appointing it. A majority of
         each committee may determine its action and may fix the time and place
         of its meetings, unless provided otherwise by the Board of Directors.
         The Board of Directors shall have the power at any time to fill
         vacancies in, to change the size of membership of, and to discharge any
         committee.

(b)      Each committee shall keep a written record of its acts and proceedings
         and shall submit that record to the Board of Directors at each regular
         meeting and at any other times as requested by the Board of Directors.
         Failure to submit the record, or failure of the Board to approve any
         action indicated therein will not, however, invalidate the action to
         the extent it has been carried out by the Corporation prior to the time
         the record of such action was, or should have been, submitted to the
         Board of Directors as provided.

Section 7. Dividends.

Subject always to the provisions of law and the Articles of Incorporation, the
Board of Directors shall have full power to determine whether any, and, if so,
what part, of the funds legally available for the payment of dividends shall be
declared in dividends and paid to the stockholders of the Corporation. The Board
of Directors may fix a sum which may be set aside or reserved over and above the
paid-in capital of the Corporation for working capital or as a reserve for any
proper purpose, and from time to time may increase, diminish, and vary this fund
in the Board's absolute judgment and discretion.

                                       6



                              ARTICLE IV. OFFICERS.

Executive Officer, a President, one or more Vice-Presidents, a Treasurer, a
Controller, a Secretary, and one or more Assistant Secretaries. In addition,

necessary. Any person may hold two, but no more than two, offices.

Section 2. Term of Office.

The principal officers shall be chosen annually by the Board of Directors at the
first meeting of the Board following the stockholders' annual meeting, or as

chosen and qualified, or until his, death, resignation, or removal.

Section 3. Removal.

Any officer may be removed from office with or without cause, at any time by the
affirmative vote of a majority of the Board of Directors then in office. Such
removal shall not prejudice the contract rights, if any, of the person so
removed.

of the term by the Board of Directors.

Section 5. Duties.

(a)      The Chairman of the Board shall preside at all meetings of the

                                       7



(d)      The Vice-Presidents, in the order designated by the Board of Directors,

         duties as are assigned from time to time by the Board of Directors.

(e)      The Secretary, the Treasurer, and the Controller shall perform those
         duties as are incident to their offices, or are properly required of

         of Incorporation or these Bylaws. The Assistant Secretaries, in the
         order of their seniority, shall, in the absence of the Secretary,
         perform the duties and exercise the powers of the Secretary, and shall
         perform any other duties as may be assigned by the Board of Directors.

(f)      Other subordinate officers appointed by the Board of Directors shall
         exercise any powers and perform any duties as may be delegated to them
         by the resolutions appointing them, or by subsequent resolutions
         adopted from time to time.

         and of any person authorized to act in his or her place during such
         period of absence or disability, the Board of Directors may from time
         to time delegate the powers and duties of that officer to any other
         officer, or any director, or any other person whom it may select.

Section 6. Salaries

The salaries of all officers of the Corporation shall be fixed by the Board of
Directors. No officer shall be ineligible to receive such salary by reason of
the fact that he is also a Director of the Corporation and receiving
compensation therefor.

                        ARTICLE V. CERTIFICATES OF STOCK.

Section 1. Form.

(a)      The interest of each stockholder of the Corporation shall be evidenced
         by certificates for shares of stock, certifying the number of shares
         represented thereby and in such form not inconsistent with the Articles
         of Incorporation as the Board of Directors may from time to time
         prescribe.

(b)      The certificates of stock shall be signed by the President or a
         Vice-President and by the Secretary or an Assistant Secretary or the
         Treasurer, and sealed with the seal of the corporation. This seal may
         be a facsimile, engraved or printed. Where any certificate is manually
         signed by a transfer agent or a transfer clerk and by a registrar, the
         signatures of the President, Vice-President, Secretary, Assistant
         Secretary, or Treasurer upon that certificate may be facsimiles,
         engraved or printed. In case any officer who has signed or whose
         facsimile signature has been placed upon any certificate shall have
         ceased to be an officer before the certificate is issued, it may be
         issued by the corporation with the same effect as if that officer had
         not ceased to be so at the time of its issue.

                                       8



Section 2. Subscriptions for Shares.

Unless the subscription agreement provides otherwise, subscriptions for shares,
regardless of the time when they are made, shall be paid in full at that time,
or in installments and at any periods, as shall be specified by the Board of
Directors. All calls for payments on subscriptions shall carry the same terms
with regard to all shares of the time class.

Section 3. Transfers.

(a)      Transfers of shares of the capital stock of the Corporation shall be
         made only on the books of the Corporation by the registered owner, or
         by his or her duly authorized attorney, with a transfer clerk or
         transfer agent appointed as provided in Section 5 of this Article of
         the Bylaws, and on surrender of the certificate or certificates for
         those shares properly endorsed with all taxes paid.

(b)      The person in whose name shares of stock stand on the books of the
         Corporation shall be deemed by the Corporation to be the owner thereof
         for all purposes. However, if any transfer of shares is made only for
         the purpose of furnishing collateral security, and that fact is made
         known to the Secretary of the Corporation, or to the Corporation's
         transfer clerk or transfer agent, the entry of the transfer may record
         that fact.

Section 4. Lost, Destroyed, or Stolen Certificates

No certificate for shares of stock in the Corporation shall be issued in place
of any certificate alleged to have been lost, destroyed, or stolen except on
production of evidence, satisfactory to the Board of Directors, of that loss,
destruction or theft, and, if the Board of Directors so requires, upon the
furnishing of an indemnity bond in such amount (but not to exceed twice the
value of the shares represented by the certificate) and with such terms and
surety as the Board of Directors, if any, in its discretion, require.

Section 5. Transfer Agent and Registrar.

The Board of Directors may appoint one or more transfer agents or transfer
clerks and one or more registrars, and may require all certificates for shares
to bear the signature or signatures of any of them.
