     The undersigned, a majority of whom are citizens of the United States,
desiring to form a corporation, for profit, under Sections 1701.01 et seq. of

Code.

     FOURTH. The number of shares which the Corporation is authorized to have
outstanding is 750 shares, all of which shall be Common shares without par
value.

     FIFTH. No holder of shares of the Corporation shall have any preemptive
right to subscribe for or to purchase any shares of the Corporation of any
class whether such shares or such class be now or hereafter authorized.

     SIXTH. The Corporation, through its Board of Directors, shall have the
right and power to repurchase any of its outstanding shares at such price and
upon such terms as may be agreed upon between the Corporation and the selling
shareholder or shareholders.

     SEVENTH. Notwithstanding any provision of the General Corporation Law of
Ohio, now or hereafter in force, requiring for any purpose the vote or consent
of the holders of shares entitling them to exercise two thirds of the voting
power of the Corporation



                                   F0990-0065

holders of shares entitling them to exercise a majority of the voting power of
the Corporation or of such class of shares thereof.

     EIGHTH. A director or officer of the Corporation shall not be disqualified
by his office from dealing or contracting with the Corporation as a vendor,
purchaser, employee, agent or otherwise. No contract or transaction shall be
void or voidable with respect to a Corporation for the reason that it is between
the Corporation and one or more of its directors or officers, or between the
Corporation and any other person in which one or more of its directors or
officers are directors, trustees, or officers, or have a financial or personal
interest, or for the reason that one or more interested directors or officers
participate in or vote at the meeting of the directors or a committee thereof
which authorizes such contract or transaction, if in any such case (a) the
material facts as to his or their relationship or interest and as to the
contract or transaction are disclosed or are known to the directors or the
committee and the directors or committee in good faith reasonably justified by
such facts, authorizes the contract or transaction by the affirmative vote of a
majority of the disinterested directors, even though the disinterested directors
constitute less than a quorum; or (b) the material facts as to his or their
relationship or interest as to the contract or transaction are disclosed or are
known to the shareholders entitled to vote thereon and the contract or
transaction is specifically approved at a meeting of the shareholders held for
such purpose by the affirmative vote of the holders of shares entitling them to
exercise a majority of the voting power of the Corporation held by persons not
interested in the contract or transaction; or (c) the contract or transaction is
fair as to the Corporation as of the time it is authorized or approved by the
directors, a committee thereof, or the shareholders. Common or interested
directors may be counted in determining the presence of a quorum at a meeting of
the directors, or of a committee thereof which authorizes the contract or
transaction.

     NINTH. All directors shall severally or collectively consent in writing to
any action to be taken by the Board of Directors, and such action shall be as
valid a corporate action as though it had been authorized in a meeting of said
Board. Said writing or writings, signed by all of the directors, shall be filed
with or entered upon the records of the Corporation. A majority of the whole
authorized number of directors may ratify any act of any officer or officers of
the Corporation. A meeting of the directors may be held through any
communications equipment if all persons participating therein can hear each
other, which shall deem to constitute presence at a meeting of the directors.

     TENTH. The amount of capital with which the Corporation shall begin
business will be not less than $500.00.

     IN WITNESS WHEREOF, the undersigned has hereunto subscribed its name this
20th day of August, 1986.
