redemption;

         (4)      the special and relative rights and preferences, if any, and

Board of Directors.

                                      4-2



                              CONTINUATION SHEET 6

6.       Other provisions for the conduct and regulation of the business and
affairs of the corporation, for its voluntary dissolution, or for limiting,
defining, or regulating the powers of the corporation, or of its directors or
stockholders, or of any class of stockholders, are as follows:

         A.       Board of Directors.

                  1.       Number, Election and Qualification. A Board of
Directors shall be elected by the stockholders at the annual meeting. The number
of directors shall be fixed by the stockholders (except as that number may be
enlarged by the Board of Directors acting pursuant to Section 3 of this
Article), but shall be not less than three, except that whenever there shall be
only two stockholders the number of directors shall be not less than two and
whenever there shall be only one stockholder or prior to the issuance of any
stock, there shall be at least one director, and shall be not more than
thirteen. Notwithstanding the foregoing provisions, at any time that the
corporation has a class of equity securities registered under the Securities and
Exchange Act of 1934, as amended, (the "Exchange Act"), then:

                           (i)      The number of directors shall be fixed only
by vote of the Board of Directors.

                           (ii)     The directors of the corporation shall be
classified with respect to the time for which they severally hold office, into
three classes, as nearly equal in number as possible; the term of office of
those of the first class ("Class I Directors") to continue until the fast annual
meeting following the date the corporation first has a class of equity
securities registered under the Exchange Act and until their successors are duly
elected and qualified; the term of office of those of the second class ("Class
II Directors") to continue until the second annual meeting following the date
the corporation first has a class of equity securities registered under the
Exchange Act and until their successors are duly elected and qualified; and the
term of office of those of the third class ("Class III Directors") to continue
until the third annual meeting following the date the corporation first has a
class of equity securities registered under the Exchange Act and until their
successors are duly elected and qualified. At each annual meeting of the
corporation, the successors to the class of directors whose term expires at that
meeting shall be elected to hold office for a term continuing until the annual
meeting held in the third year following the year of their election and until
their successors are duly elected and qualified.

         2.       Vacancies. Any vacancy in the Board of Directors, however
occurring, including a vacancy resulting from the enlargement of the Board, may
be filled by the stockholders or, in the absence of stockholder action, by the
directors. Each such successor shall hold office for the unexpired term of his
predecessor and until his successor is chosen and qualified or until his earlier
death, resignation or removal.

         3.       Enlargement of the Board. The Board of Directors may be
enlarged by the stockholders at any meeting or by vote of a majority of the
directors then in office.

         4.       Tenure. Except as otherwise provided by law, these Restated
Articles of Organization or the By-laws, directors shall hold office until the
next annual meeting of stockholders and until their successors are chosen and
qualified. Any director may resign by

                                      6-1



delivering his written resignation to the corporation at its principal office or
the President, Clerk or Secretary. Such resignation shall be effective upon
receipt unless it is specified to be effective at some other time or upon the
happening of some other event.

         5.       Removal. A director may be removed from office (a) with or
without cause by the vote of the holders of a majority of the shares entitled to
vote in the election of Directors, provided that the directors of a class
elected by a particular class of stockholders may be removed only by the vote of
the holders of a majority of the shares of the particular class of stockholders
entitled to vote for the election of such Directors; or (b) for cause by vote of
a majority of the Directors then in office. A director may be removed for cause
only after a reasonable notice and opportunity to be heard before the body
proposing to remove him.

         B.       Liability of Directors.

         The corporation eliminates the personal liability of each director to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director notwithstanding any provision of law imposing such liability;
provided, however, that, to the extent provided by applicable law, this
provision shall not eliminate or limit the liability of a director (i) for any
breach of the director's duty of loyalty to the corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 61 or 62 or
successor provisions of the Massachusetts Business Corporation Law, or (iv) for
any transaction from which the director derived an improper personal benefit.
This provision shall not eliminate or limit the liability of a director of the
corporation for any act or omission occurring prior to the date on which this
provision becomes effective. No amendment to or repeal of this provision shall
apply to or have any effect on the liability or alleged liability of any
director for or with respect to any acts or omissions of such director occurring
prior to such amendment or repeal.

         C.       Indemnification.

                  1.       Actions. Suits and Proceedings. The corporation shall
indemnify each 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, whether
civil, criminal, administrative or investigative, by reason of the fact that he
is or was, or has agreed to become, a director or officer of the corporation, or
is or was serving, or has agreed to serve, at the request of the corporation, as
a director or officer of, or in a similar capacity with, another organization or
in any capacity with respect to any employee benefit plan of the corporation
(all such persons being referred to hereafter as an "Indemnitee"), or by reason
of any action alleged to have been taken or omitted in such capacity against all
expenses (including attorneys' fees), judgments and fines incurred by him or on
his behalf in connection with such action, suit or proceeding and any appeal
therefrom, unless the Indemnitee shall be finally adjudicated in such action,
suit or proceeding not to have acted in good faith in the reasonable belief that
his action was in the best interests of the corporation or, to the extent such
matter relates to service with respect to an employee benefit plan, in the best
interests of the participants or beneficiaries of such employee benefit plan.
Notwithstanding anything to the contrary in this Article, except as set forth in
Section 5 below, the corporation shall not indemnify an Indemnitee seeking
indemnification in connection with a

                                      6-2



proceeding (or part thereof) initiated by the Indemnitee unless the initiation
thereof was approved by the Board of Directors of the corporation.

                  2.       Settlements. The right to indemnification conferred
in this Article shall include the right to be paid by the corporation for
amounts paid in settlement of any such action, suit or proceeding and any appeal
therefrom, and all expenses (including attorneys' fees) incurred in connection
with such settlement, pursuant to a consent decree or otherwise, unless and to
the extent it is determined pursuant to Section 5 below that the Indemnitee did
not act in good faith in the reasonable belief that his action was in the best
interests of the corporation or, to the extent such matter relates to service
with respect to an employee benefit plan, in the best interests of the
participants or beneficiaries of such employee benefit plan.

                  3.       Notification and Defense of Claim. As a condition
precedent to his right to be indemnified, the Indemnitee must notify the
corporation in writing as soon as practicable of any action, suit, proceeding or
investigation involving his for which indemnify will or could be sought. With
respect to any action, suit, proceeding or investigation of which the
corporation is so notified, the corporation will be entitled to participate
therein at its own expense and/or to assume the defense thereof at its own
expense, with legal counsel reasonably acceptable to the Indemnitee. After
notice from the corporation to the Indemnitee of its election so to assume such
defense, the corporation shall not be liable to the Indemnitee for any legal or
other expenses subsequently incurred by the Indemnitee in connection with the
such claim, other than as provided below in this Section 3. The Indemnitee shall
have the right to employ his own counsel in connection with such claim, but the
fees and expenses of such counsel incurred after notice from the corporation of
its assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the corporation, (ii) counsel to the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which case the fees and expenses
of counsel for the Indemnitee shall be at the expense of the corporation, except
as otherwise expressly provided by this Article. The corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the corporation or as which counsel for the
Indemnitee shall have reasonably made the conclusion provided for in clause (ii)
above.

                  4.       Advance of Expenses. Subject to the provisions of
Section 5 below, in the event that the corporation does not assume the defense
pursuant to Section 3 of this Article of any action, suit, proceeding or
investigation of which the corporation receives notice under this Article, any
expenses (including attorneys' fees, incurred by an Indemnitee in defending a
civil or criminal action, suit, proceeding or investigation or any appeal
therefrom shall be paid by the corporation in advance of the final disposition
of such matter, provided, however, that the payment of such expenses incurred by
an Indemnitee in advance of the final disposition of suci matter shall be made
only upon receipt of an undertaking by or on behalf of the Indemnitee to repay
all amounts so advanced in the event that it shall ultimately be determined that
the Indemnitee is not entitied to be indemnified by the corporation as
authorized in this Article. Such undertaking may be accepted without reference
to the financial ability of the Indemnitee to make such repayment.

                                      6-3



                  5.       Procedure for Indemnification. In order to obtain
indemnification or advancement of expenses pursuant to Section 1, 2 or 4 of this
Article, the Indemnitee shall submit to the corporation a written request,
including in such request such documentation and information as is reasonably
available to the Indemnitee and is reasonably necessary to determine whether and
to what extent the Indemnitee is entitled to indemnification or advancement of
expenses. Any such indemnification or advancement of expenses shall be made
promptly, and in any event within sixty days after receipt by the corporation of
the written request of the Indemnitee, unless the corporation determines, by
clear and convincing evidence, within such sixty-day period that the Indemnitee
did not meet the applicable standard of conduct set forth in Section 1 or 2, as
the case may be. Such determination shall be made in each instance by (a) a
majority vote of a quorum of the directors of the corporation, (b) a majority
vote of a quorum of the outstanding shares of stock of all classes entitled to
vote for directors, voting as a single class, which quorum shall consist of
stockholders who are not at that time parties to the action, suit or proceeding
in question, (c) independent legal counsel (who may be regular legal counsel to
the corporation), or (d) a court of competent jurisdiction.

                  6.       Remedies. The right to indemnification or advances as
granted by this Article shall be enforceable by the Indemnitee in any court of
competent jurisdiction if the corporation denies such request, in whole or in
part, or if no disposition thereof is made within the sixty-day period refereed
to above in Section 5. Unless otherwise provided by law, the burden of proving
that the Indemnitee is not entitled to indemnification or advancement of
expenses under this Article shall be on the corporation. Neither the failure of
the corporation to have made a determination prior to the commencement of such
action that indemnification is proper in the circumstances because the
Indemnitee has met the applicable standard of conduct, nor an actual
determination by the corporation pursuant to Section 5 that the Indemnitee has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the Indemnitee has not met such applicable standard of
conduct. The Indemnitee's expenses (including attorneys' fees) incurred in
connection with successfully establishing his right to indemnification, in whole
or in part, in any such proceeding shall also be indemnified by the corporation.

                  7.       Subsequent Amendment. No amendment, termination or
repeal of this Article or of the relevant provisions of Chapter 156B of the
Massachusetts General Laws or any other applicable laws shall affect or diminish
in any way the rights of any Indemnitee to indemnification under the provisions
hereof with respect to any action, suit, proceeding or investigation arising out
of or relating to any actions, transactions or facts occurring prior to the
final adoption of such amendment, termination or repeal.

                  8.       Other Rights. The indemnification and advancement of
expenses provided by this Article shall not be deemed exclusive of any other
rights to which an Indemnitee seeking indemnification or advancement of expenses
may be entitled under any law (common or statutory), agreement or vote of
stockholders or directors or otherwise, both as to action in his official
capacity and as to action in any other capacity while holding office for the
corporation, and shall continue as to an Indemnitee who has ceased to be a
director or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of the Indemnitee. Nothing contained in this
Article shall be deemed to prohibit, and the corporation is specifically
authorized to enter into, agreements with officers and directors providing
indemnification rights

                                      6-4



and procedures different from those set forth in this Article. In addition, the
corporation may, to the extent authorized from time to time by its Board of
Directors, grant indemnification rights to other employees or agents of the
corporation or other persons serving the corporation and such rights may be
equivalent to, or greater or less than, those set forth in this Article.

                  9.       Partial Indemnification. If an Indemnitee is entitled
under any provision of this Article to indemnification by the corporation for
some or a portion of the expenses (including attorneys' fees), judgments, fines
or amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with any action, suit, proceeding or investigation and any
appeal therefrom but not, however, for the total amount thereof, the corporation
shall nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

                  10.      Insurance. The corporation may purchase and maintain
insurance, at its expense, to protect itself and any director, officer, employee
or agent of the corporation or another organization or employee benefit plan
against any expense, liability or loss 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 such person against such expense, liability or loss under
Chapter 156B of the Massachusetts General Laws.

           (Pursuant to Chapter 156B, Section 26, of the General Laws

                         ------------------------------

      PAREXEL International Corporation, a corporation organized and existing
under the laws of the Commonwealth of Massachusetts (hereinafter called the
"Corporation"), hereby certifies that the following votes were adopted by the
Board of Directors of the Corporation at a meeting duly called and held on March
27, 2003:

      VOTED: That pursuant to the authority granted to and vested in the Board
of Directors of the Corporation (hereinafter called the "Board") in accordance
with the provisions of its Articles of Organization, as amended, the Board
hereby creates a series of Preferred Stock, $.01 par value per share (the
"Preferred Stock"), of the Corporation and hereby states the designation and
number of shares, and fixes the relative rights, preferences and limitations
thereof as follows:

      Series A Junior Participating Preferred Stock:

      Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be fifty thousand (50,000). Such number of shares may be increased
or decreased by vote of the Board prior to issuance; provided, that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

      Section 2. Dividends and Distributions.

      (A) Subject to the rights of the holders of any shares of any series of
Preferred Stock (or any similar stock) ranking prior and superior to the Series
A Preferred Stock with respect to dividends, the holders of shares of Series A
Preferred Stock, in preference to the holders of



Common Stock, par value $.01 per share (the "Common Stock"), of the Corporation,
and of any other junior stock, shall be entitled to receive, when, as and if
declared by the Board out of funds of the Corporation legally available for the
payment of dividends, quarterly dividends payable in cash on the last day of
each fiscal quarter of the Corporation in each year (each such date being
referred to herein as a "Quarterly Dividend Payment Date"), commencing on the
first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (a) $10 or (b) subject to the
provision for adjustment hereinafter set forth, 1,000 times the aggregate per
share amount of all cash dividends, and 1,000 times the aggregate per share
amount (payable in kind) of all non-cash dividends or other distributions, other
than a dividend payable in shares of Common Stock or a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise), declared
on the Common Stock since the immediately preceding Quarterly Dividend Payment
Date or, with respect to the first Quarterly Dividend Payment Date, since the
first issuance of any share or fraction of a share of Series A Preferred Stock.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision,
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event. In
the event the Corporation shall at any time declare or pay any dividend on the
Series A Preferred Stock payable in shares of Series A Preferred Stock, or
effect a subdivision, combination or consolidation of the outstanding shares of
Series A Preferred Stock (by reclassification or otherwise than by payment of a
dividend in shares of Series A Preferred Stock) into a greater or lesser number
of shares of Series A Preferred Stock, then in each such case the amount to
which holders of shares of Series A Preferred Stock were entitled immediately
prior to such event under clause (b) of the first sentence of this Section 2(A)
shall be adjusted by multiplying such amount by a fraction, the numerator of
which is the number of shares of Series A Preferred Stock that were outstanding
immediately prior to such event and the denominator of which is the number of
shares of Series A Preferred Stock outstanding immediately after such event.

      (B) The Corporation shall declare a dividend or distribution on the Series
A Preferred Stock as provided in paragraph (A) of this Section immediately after
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock) and the Corporation shall pay such
dividend or distribution on the Series A Preferred Stock before the dividend or
distribution declared on the Common Stock is paid or set apart; provided that,
in the event no dividend or distribution shall have been declared on the Common
Stock during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $10 per share on the
Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

      (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of



issue of such shares, unless the date of issue of such shares is prior to the
record date for the first Quarterly Dividend Payment Date, in which case
dividends on such shares shall begin to accrue from the date of issue of such
shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a
date after the record date for the determination of holders of shares of Series
A Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Preferred Stock in an amount less than the total amount of
such dividends at the time accrued and payable on such shares shall be allocated
pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board may fix a record date for the determination of holders of
shares of Series A Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be not more than 60 days
prior to the date fixed for the payment thereof.

      Section 3. Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

      (A) Subject to the provision for adjustment hereinafter set forth, each
share of Series A Preferred Stock shall entitle the holder thereof to 1,000
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision,
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event shall be adjusted
by multiplying such number by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event. In the event the Corporation shall
at any time declare or pay any dividend on the Series A Preferred Stock payable
in shares of Series A Preferred Stock, or effect a subdivision, combination or
consolidation of the outstanding shares of Series A Preferred Stock (by
reclassification or otherwise than by payment of a dividend in shares of Series
A Preferred Stock) into a greater or lesser number of shares of Series A
Preferred Stock, then in each such case the number of votes per share to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Series A Preferred Stock that were
outstanding immediately prior to such event and the denominator of which is the
number of shares of Series A Preferred Stock outstanding immediately after such
event.

      (B) Except as otherwise provided herein, in the Articles of Organization,
as amended, or by law, the holders of shares of Series A Preferred Stock and the
holders of shares of Common Stock and any other capital stock of the Corporation
having general voting rights shall vote together as one class on all matters
submitted to a vote of stockholders of the Corporation.

      (C) (i) If at any time dividends on any Series A Preferred Stock shall be
in arrears in an amount equal to six quarterly dividends thereon, the holders of
the Series A Preferred Stock, voting as a separate series from all other series
of Preferred Stock and classes of capital stock, shall be entitled to elect two
members of the Board in addition to any Directors elected by



any other series, class or classes of securities and the authorized number of
Directors will automatically be increased by two. Promptly thereafter, the Board
of the Corporation shall, as soon as may be practicable, call a special meeting
of holders of Series A Preferred Stock for the purpose of electing such members
of the Board. Such special meeting shall in any event be held within 45 days of
the occurrence of such arrearage.

            (ii) During any period when the holders of Series A Preferred Stock,
voting as a separate series, shall be entitled and shall have exercised their
right to elect two Directors, then, and during such time as such right
continues, (a) the then authorized number of Directors shall be increased by
two, and the holders of Series A Preferred Stock, voting as a separate series,
shall be entitled to elect the additional Directors so provided for, and (b)
each such additional Director shall not be a member of any existing class of the
Board, but shall serve until the next annual meeting of stockholders for the
election of Directors, or until his successor shall be elected and shall
qualify, or until his right to hold such office terminates pursuant to the
provisions of this Section 3(C).

            (iii) A Director elected pursuant to the terms hereof may be removed
with or without cause by the holders of Series A Preferred Stock entitled to
vote in an election of such Director.

            (iv) If, during any interval between annual meetings of stockholders
for the election of Directors and while the holders of Series A Preferred Stock
shall be entitled to elect two Directors, there is no such Director in office by
reason of resignation, death or removal, then, promptly thereafter, the Board
shall call a special meeting of the holders of Series A Preferred Stock for the
purpose of filling such vacancy and such vacancy shall be filled at such special
meeting. Such special meeting shall in any event be held within 45 days of the
occurrence of such vacancy.

            (v) At such time as the arrearage is fully cured, and all dividends
accumulated and unpaid on any shares of Series A Preferred Stock outstanding are
paid, and, in addition thereto, at least one regular dividend has been paid
subsequent to curing such arrearage, the term of office of any Director elected
pursuant to this Section 3(C), or his successor, shall automatically terminate,
and the authorized number of Directors shall automatically decrease by two, the
rights of the holders of the shares of the Series A Preferred Stock to vote as
provided in this Section 3(C) shall cease, subject to renewal from time to time
upon the same terms and conditions, and the holders of shares of the Series A
Preferred Stock shall have only the limited voting rights elsewhere herein set
forth.

      (D) Except as set forth herein, or as otherwise provided by law, holders
of Series A Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to vote
with holders of Common Stock as set forth herein) for taking any corporate
action.



      Section 4. Certain Restrictions.

      (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:

            (i) declare or pay dividends, or make any other distributions, on
any shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Preferred Stock;

            (ii) declare or pay dividends, or make any other distributions, on
any shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except dividends paid ratably on the Series A Preferred Stock and all such
parity stock on which dividends are payable or in arrears in proportion to the
total amounts to which the holders of all such shares are then entitled;

            (iii) redeem or purchase or otherwise acquire for consideration
shares of any stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Preferred Stock, provided that the
Corporation may at any time redeem, purchase or otherwise acquire shares of any
such junior stock in exchange for shares of any stock of the Corporation ranking
junior (either as to dividends or upon dissolution, liquidation or winding up)
to the Series A Preferred Stock; or

            (iv) redeem or purchase or otherwise acquire for consideration any
shares of Series A Preferred Stock, or any shares of stock ranking on a parity
with the Series A Preferred Stock, except in accordance with a purchase offer
made in writing or by publication (as determined by the Board) to all holders of
such shares upon such terms as the Board, after consideration of the respective
annual dividend rates and other relative rights and preferences of the
respective series and classes, shall determine in good faith will result in fair
and equitable treatment among the respective series or classes.

      (B) The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

      Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Articles of Organization, as amended, or in any other Certificate of Vote
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.



      Section 6. Liquidation, Dissolution or Winding Up.

      (A) Upon any liquidation, dissolution or winding up of the Corporation, no
distribution shall be made (1) to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series A Preferred Stock unless, prior thereto, the holders of shares of Series
A Preferred Stock shall have received $1,000 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up.

      (B) Neither the consolidation, merger or other business combination of the
Corporation with or into any other corporation nor the sale, lease, exchange or
conveyance of all or any part of the property, assets or business of the
Corporation shall be deemed to be a liquidation, dissolution or winding up of
the Corporation for purposes of this Section 6.

      (C) In the event the Corporation shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision, combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the aggregate amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event under the proviso
in clause (1) of paragraph (A) of this Section 6 shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event. In the event the Corporation shall
at any time declare or pay any dividend on the Series A Preferred Stock payable
in shares of Series A Preferred Stock, or effect a subdivision, combination or
consolidation of the outstanding shares of Series A Preferred Stock (by
reclassification or otherwise than by payment of a dividend in shares of Series
A Preferred Stock) into a greater or lesser number of shares of Series A
Preferred Stock, then in each such case the aggregate amount to which holders of
shares of Series A Preferred Stock were entitled immediately prior to such event
under the proviso in clause (1) of paragraph (A) of this Section 6 shall be
adjusted by multiplying such amount by a fraction, the numerator of which is the
number of shares of Series A Preferred Stock that were outstanding immediately
prior to such event and the denominator of which is the number of shares of
Series A Preferred Stock outstanding immediately after such event.

      Section 7. Consolidation, Merger, etc. Notwithstanding anything to the
contrary contained herein, in case the Corporation shall enter into any
consolidation, merger, combination or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case each share of Series A
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to 1,000



times the aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share of
Common Stock is changed or exchanged. In the event the Corporation shall at any
time declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision, combination or consolidation of the outstanding
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in shares of Common Stock) into a greater or lesser number of shares of
Common Stock, then in each such case the amount set forth in the preceding
sentence with respect to the exchange or change of shares of Series A Preferred
Stock shall be adjusted by multiplying such amount by a fraction, the numerator
of which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event. In the event the
Corporation shall at any time declare or pay any dividend on the Series A
Preferred Stock payable in shares of Series A Preferred Stock, or effect a
subdivision, combination or consolidation of the outstanding shares of Series A
Preferred Stock (by reclassification or otherwise than by payment of a dividend
in shares of Series A Preferred Stock) into a greater or lesser number of shares
of Series A Preferred Stock, then in each such case the amount set forth in the
first sentence of this Section 7 with respect to the exchange or change of
shares of Series A Preferred Stock shall be adjusted by multiplying such amount
by a fraction, the numerator of which is the number of shares of Series A
Preferred Stock that were outstanding immediately prior to such event and the
denominator of which is the number of shares of Series A Preferred Stock
outstanding immediately after such event.

      Section 8. No Redemption. The shares of Series A Preferred Stock shall not
be redeemable.

      Section 9. Rank. The Series A Preferred Stock shall rank, with respect to
the payment of dividends and the distribution of assets, junior to all series of
any other class of the Preferred Stock issued either before or after the
issuance of the Series A Preferred Stock, unless the terms of any such series
shall provide otherwise.

      Section 10. Amendment. At such time as any shares of Series A Preferred
Stock are outstanding, the Articles of Organization, as amended, of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least two-thirds of the outstanding shares of Series A Preferred Stock, voting
together as a single class.

      Section 11. Fractional Shares. Series A Preferred Stock may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and have the benefit of all other rights of holders
of Series A Preferred Stock.
