other business as may properly come before the meeting, shall be held at such

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;

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.

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

                  If a notice of any adjourned special meeting of stockholders
is sent to all stockholders entitled to vote thereat, stating that it will be
held with those present constituting a quorum, then except as otherwise required

such person as may be chosen by the Board, or if not so chosen, as selected by
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
Chairperson of the meeting. In the absence of the Secretary of the Corporation,

entitled to vote which is registered in such stockholder's name on the record
date for the meeting, except as otherwise provided herein or required by law.

                  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 therefor by a stockholder entitled to vote or such
stockholder's 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. Every vote taken by ballots shall be counted by an
inspector or inspectors appointed by the Chairperson of the meeting.

                  No proxy shall be voted on or after three (3) years from its

of the stockholders entitled to vote at the meeting and the number of shares
held by each of them.

                  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 in writing,

or activity for which corporations may be organized under the General
Corporation Law of the State of Delaware; provided that the Corporation's
activities shall be confined to the maintenance and management of its intangible
investments and the collection and distribution of the income from such
investments or from tangible property physically located outside Delaware, all
as defined in, and in such manner to qualify for exemption from income taxation
under, Section 1902(b)(8) of Title 30 of the Delaware Code, or under the
corresponding provision of any subsequent law; provided further that the
Corporation shall be empowered to conduct such other activities as permitted by
said Section 1902(b)(8) or the corresponding provision of any subsequent law in
such manner to qualify for exemption from income taxation under said Section
1902(b)(8) or the corresponding provision of any subsequent law. For purposes of

                   ARTICLE VII - INDEMNIFICATION AND INSURANCE

                  Section 1.  Scope.

                  Except as prohibited by law, every person shall be entitled as
of right to be indemnified by the Corporation against reasonable expense and any
liability paid or incurred by such person in connection with any actual or
threatened claim, action, suit or proceeding, civil, criminal, administrative,
investigative or other, whether brought by or in the right of the Corporation or
otherwise, by reason of such person being or having been a director or officer
of the Corporation or by reason of the fact that such officer or director of the
Corporation is or was serving at the request of the Corporation as a director,
officer, employee, fiduciary or other representative of another corporation,
partnership, joint venture, trust, employee benefit plan or other entity (such
claim, action, suit or proceeding hereinafter being referred to as "action").
Such indemnification shall include the right to have expenses incurred by such
person in connection with an action paid in advance by the Corporation prior to
final disposition of such action, subject to subsequent determination of the
right to be so indemnified. Persons who are not directors or officers of the
Corporation may be similarly indemnified in respect of service to the
Corporation or to another such entity at the request of the Corporation to the
extent the Board of Directors at any time determines that such person is
entitled to the benefits of this Article. As used herein, "expense" shall
include fees and expenses of counsel selected by such person; and "liability"
shall include amounts of judgments, excise taxes, fines and penalties, and
amounts paid in settlement.

                  Section 2.  Means of Indemnification.

                  The Corporation may purchase and maintain insurance to protect
itself and any person eligible to be indemnified hereunder against any liability
or expense asserted or incurred by such person in connection with any action,
whether or not the Corporation would have the power to indemnify such person
against such liability or expense by law or under this Article. The Corporation
may create a trust fund, grant a security interest, cause a letter of credit to
be issued or use other means (whether or not similar to the foregoing) to ensure
the payment of such sums as may become necessary to effect indemnification as
provided herein.

                  Section 3.  Agreement for Indemnification.

                  The Corporation shall have the express authority to enter into
such agreements as the Board of Directors deems appropriate for the
indemnification, including advancement of expenses, of present or future
directors and officers of the Corporation and other persons in connection with
their service to, or status with, the Corporation or any other corporation,
partnership, joint venture, trust, employee benefit plan or other entity with
whom such director, officer or other person is serving at the request of the
Corporation.

                  Section 4.  Nature of Right of Indemnification.

                  The right of indemnification provided for herein (i) shall not
be deemed exclusive of any other rights to which those seeking indemnification
hereunder may be entitled, (ii) shall be deemed to create contractual rights in
favor of persons entitled to indemnification hereunder, (iii) shall continue as
to persons who have ceased to have the status pursuant to which they were
entitled or were determined to be entitled to indemnification hereunder and
shall inure to the benefit of the heirs and legal representatives of persons
entitled to indemnification hereunder and (iv) shall be applicable to actions,
suits or proceedings commenced after the adoption hereof, whether arising from
acts or omissions occurring before or after the adoption hereof. The rights of
indemnification provided for herein may not be amended, modified or repealed so

which a person is entitled under this Article is not paid in full by the
Corporation within 30 days after a written claim has been received by the
Corporation, the claimant may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim. The Corporation shall
promptly reimburse the claimant for all costs and expenses, including attorneys'
fees, incurred in bringing and pursuing such action, subject to the
Corporation's right to recover the amount of such reimbursement in the event and
to the extent that it is ultimately determined by the final judgment of a court
