(7) days before the meeting to each Stockholder entitled to vote thereat and to
each Stockholder who is otherwise entitled by law or by the Articles of
Organization to such notice, by leaving such notice with him or at his residence
or usual place of business, or by mailing it, postage prepaid, and addressed to
such Stockholder at his address as it appears in the records of the Corporation.
Such notice shall be given by the Clerk, or in case of the death, absence,
incapacity or refusal of the Clerk, by any other officer or by a person
designated either by the Clerk, by the person or persons calling the meeting or
by the Board of Directors. Whenever notice of a meeting is required to be given
a Stockholder under any provision of law, or of the Articles of Organization, or
of these By-Laws, a written waiver thereof, executed before or after the meeting
by such Stockholder or his attorney thereunto authorized, and filed with the
records of the meeting, shall be deemed equivalent to such notice.

          Section 5. Quorum.

          At any meeting of the Stockholders, a quorum shall consist of a
majority in interest of all stock issued and outstanding and entitled to vote at
the meeting; except that if two or more classes or series of stock are entitled
to vote on any matter as separate classes or series, then a quorum for that


                                       -3-



matter shall consist of a majority in interest of all stock of that class or
series issued and outstanding; and except when a larger quorum is required by
law, by the Articles of Organization or by these By-Laws. Stock owned directly
or indirectly by the Corporation, if any, shall not be deemed outstanding for
this purpose. Any meeting may be adjourned from time to time by a majority of
the votes properly cast upon the question, whether or not a quorum is present,
and the meeting may be held as adjourned without further notice.

          Section 6. Action by Vote.

          When a quorum is present at any meeting, a plurality of the votes
properly cast for election to any office shall elect to such office, and a
majority of the vote properly cast upon any question other than an election to
an office shall decide the question, except when a larger vote is required by
law, by the Articles of Organization or by these By-Laws. No ballot shall be

represented at the meeting and entitled to vote in the election.

          Stockholders entitled to vote shall have one vote for each share of
stock held by them of record as of the date of the vote and a proportionate vote

          Section 8. Action by Consent.

          Any action required or permitted to be taken at any meeting of the
Stockholders may be taken without a meeting if all Stockholders entitled to vote
on the matter consent to the action in writing and the written consents are
filed with the records of the meetings of Stockholders. Such consents shall be
treated for all purposes as a vote at a meeting.

          Section 9. Proxies.

          Stockholders entitled to vote may vote either in person or by proxy in
writing dated not more than six months before the meeting named therein, which
proxies shall be filed with the Clerk or other person responsible to record the
proceedings of the meeting before being voted. Unless otherwise specifically
limited by their terms, such proxies shall entitle the holders thereof to vote
at any adjournment of such meeting but shall not be valid after the final
adjournment of such meeting. A proxy with respect to stock held in the name of
two or more persons shall be valid if executed by any one of them unless at or
prior to exercise of the proxy the Corporation receives specific written notice
to the contrary from any one of them. A proxy purporting to be executed by or on
behalf of a Stockholder shall be deemed valid unless challenged at or prior to
its exercise. The burden of proving invalidaty shall rest on the challenger.

as have the right to vote thereon, and each shall hold office until the next
Annual Election of Directors and until his successor is chosen and qualified or
until he sooner dies, resigns, is removed or becomes disqualified. No Director

Directors may fix from time to time and, when so fixed, no notice thereof need

are fixed shall be given notice of the fixing of such times and places. The
first meeting of the Board of Directors following the Annual Meeting of the
Stockholders may be held without notice immediately after and at the same place
as the Annual Meeting of the Stockholders or the Special Meeting held in lieu

Board of Directors with the same force and effect as if held or transacted at
such meeting.

          Section 4. Special Meetings.

notice by mail at least forty-eight hours or by telegram at least twenty-four
hours before the meeting addressed to him at his usual or last known business or

twenty-four hours before the meeting. Notice of a meeting need not be given to
any Director if a written waiver of notice, executed by him before or after the
meeting is filed with the records of the meeting, or to any Director who attends
the meeting without protesting prior thereto or at its commencement the lack of
notice to him. Neither notice of a meeting nor a waiver of a notice need specify
the purposes of the meeting.

          Section 6. Quorum

          At any meeting of the Directors, a quorum for any election or for the
consideration of any question shall consist of a majority of the Diectors then

be requisite and sufficient for election to any office and shall decide any
question brought before such meeting, except in any case where a larger vote is
required by law, by the Articles of Organization or by these By-Laws.

          Section 7. Action by Consent.

          Any action required or permitted to be taken at any meeting of the
Directors may be taken without a meeting if all the Directors consent to the
action in writing and the written consents are filed with the records of the
meetings of the Directors. Such consent shall be treated for all purposes as a
vote of the Directors at a meeting.

          Section 8. Committees.

          The Board of Directors, by vote of a majority of the Directors then in
office, may elect from its number an Executive Committee or other committees and
may delegate thereto some or all of its powers except those which by law, by the
Articles of Organization, or by these By-Laws may not be delegated. Except as
the Board of Directors may otherwise determine, any such committee may make
rules for the conduct of its business, but unless otherwise provided by the
Board of Directors or in such rules, its business shall be conducted so far as
possible in the same manner as is provided by these By-Laws for the Board of
Directors. All members of such committees shall hold such offices at the
pleasure of the Board of Directors. The Board of Directors may abolish any such
committee at any time. Any committee to which the Board of Directors delegates
any of its powers or duties shall keep records of its meetings and shall upon
request report its action to the Board of Directors. The Board of Directors
shall have power to rescind any action of any committee, but no such rescission
shall have retroactive effect.

any person serving or who has served as a Director or Officer of the
corporation, or at its request as a Director, Trustee, Officer, Employee or
other Agent of any organization in which the corporation owns shares or of which
it is a creditor against all liabilities and expenses, including amounts paid in
satisfaction of judgments, in compromise or as fines and penalties, and counsel
fees, reasonably incurred by him in connection with the defense or disposition
of any action, suit or other proceeding, whether civil or criminal, in which he
may be involved or with which he may be threatened, while serving or thereafter,
by reason of his being or having been such a Director, Officer, Trustee,
Employee or Agent. No indemnificatioon shall be provided for any person with
respect to any matter as to which he shall have been adjudicated in any
proceeding not to have acted in good faith in the reasonable belief that his
action was in the best interests of the corporation. As to any matter disposed
of by a compromise payment by such Director, Officer, Trustee, Employee or
Agent, pursuant to a consent decree or otherwise, no indemnification either for
said payment or for any other expenses shall be provided unless:

     (a)  such compromise shall be approved as in the best interests of the
          corporation, after notice that it involves such indemnification:


                                      -15-



          (i) by a disinterested majority of the Directors then in office; or

          (ii) by the holders of a majority of the outstanding stock at the time

               exclusive of any stock owned by any interested Director or
               Officer; or

     (b)  in the absence of action by disinterested Directors or Stockholders,
          there has been obtained at the request of a majority of the Directors
          then in office an opinion in writing of independent legal counsel to
          the effect that such Director or Officer appears to have acted in good
          faith in the reasonable belief that his action was in the best
          interests of the corporation.

         Expenses, including counsel fees, reasonably incurred by any such
Director, Officer, Trustee, Employee or Agent in connection with the defense or
disposition of any such action, suit or other proceeding may be paid from time
to time by the corporation in advance of the final disposition thereof upon
receipt of an undertaking by such individual to repay the amounts so paid to the
corporation if it is ultimately determined that indemnification for such
expenses is not authorized under this section. The right of indemnification
hereby provided shall not be exclusive of or affect any other rights to which
any such Director, Officer, Trustee, Employee or Agent shall affect any rights
to indemnification to which corporate personnel other than such Directors,
Officers, Trustees, Employees or Agents may be entitled by contract or otherwise
under law. As used in this Article the terms "Director", "Officer", "Trustee",

determine the conditions upon which a new certificate of stock may be issued in
place of any certificate alleged to have been lost, mutilated or destroyed. It

          The Board of Directors may fix in advance a time not more than sixty
(60) days before (i) the date of any meeting of the Stockholders or (ii) the
date for the payment of any dividend or the making of any distribution to
Stockholders or (iii) the last day on which the consent or dissent of
stockholders may be effectively expressed for any purpose, as the record date
for determining the Stockholders having the right to notice and to vote at such
meeting, or the right to receive such dividend or distribution, or the right to
give such consent or dissent. If a record date is set, only Stockholders of
record on the date shall have such right notwithstanding any transfer of stock
on the records of the corporatioon after the record date. Without fixing such
record date, the Board of Directors may close the transfer records of the
corporation for all or any part of such sixty-day period.

the record date for determining Stockholders having the right 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, and the record date for
determining Stockholders for any other purpose shall be at the close of business
on the day on which the Board of Directors acts with respect thereto.

                                   ARTICLE XI

                        Restrictions on Transfer of Stock

          No Stockholder of the Corporation or his executor, administrator, or
personal representative shall encumber or dispose of the stock of the
Corporation which he now owns or may hereafter acquire, except as follows:

          (a) Any Stockholder may transfer any part or all of such stock by
testate direction or intestate distribution at the time of his death to or for
the benefit of any person or persons, or by gift to, or in trust for the benefit
of himself, his spouse, his parent or parents, or any descendant or descendants
of his. In case of any such transfer, the legatees, heirs, next of kin, donees,
or other transferees shall receive and hold such stock subject to the
restrictions or encumbrance and disposition, set forth in this Article.

          (b) Any Stockholder who desires to sell all or any part of such stock
shall first offer in writing such stock for sale to the corporation at the same
price and upon the same terms offered to such Stockholder by a bona fide
prospective puchaser of such shares. The corporation shall have the option for
ten (10) days after its receipt of such written offer to accept such offer. If,
within such ten-day period, the Corportion shall fail to accept such offer in
its entirety, its option hereunder as to such offer shall terminate. Thereupon,
the Stockholder so desiring to sell all or part of his stock shall make the same
offer (being an offer in writing to sell such stock at the same price and upon
the same terms offered to such Stockholder or a bona fide prospective purchaser
of such shares) to all of the


                                      -24-



other then Stockholders of the Corporation (as a group), and shall give written
notice of such offer to all of the other then Stockholders. Such other
Stockholders shall have the option for thirty (30) days after their receipt of
such written offer to accept such offer in such proportions among themselves as
they may agree, and if they do not agree, then each such Stockholder who desires
to accept such offer shall have the right to purchase such a fraction of such
shares of stock as is computed as follows:

     (i)  The numerator of the fraction shall be the number corresponding to the
          number of shares of stock of the Corporation then owned by such
          Stockholder who desires to accept such offer;

     (ii) The denominator of such fraction shall be the number corresponding to
          the sum of all of the shares of stock then owned by all of the then
          Stockholders who desire to accept such offer;

provided, however, that no Stockholder shall have the right to purchase any part
of the shares so offered for sale unless all of such shares so offered for sale
are purchased, pursuant to such offer, by one or more of such offeree
Stockholders.

          If no Stockholder or Stockholders exercise such option within the
aforesaid thirty-day period, then the Stockholder so desiring to sell part or
all of his stock shall have the right for a period ending on the sixtieth (60th)
day after the expiration of the aforesaid thirty-day period, to sell such stock
to, and only to, the aforesaid bona fide prospective purchaser in the same
quantity, at the same price, and upon the same terms as


                                      -25-



were offered to the other Stockholders and/or the Corporation. Upon the
expiration of such sixty-day period, if such Stockholder does not sell such
stock, all of the restrictions imposed by this Article shall apply to all of the
stock owned by such Stockholder.


                                      -26-
