Bylaws expressly conferred upon it, the Board of Directors may
exercise all such powers of the Corporation and do all such
lawful acts and things as are not by statute or by the
Certificate of Incorporation or by these Bylaws directed or
required to be exercised or done by the stockholders.

	                 RIGHT TO INDEMNIFICATION

    16.(a) Each person who was or is made a party or is
threatened to be made a party to or is involved in any action,
suit or proceeding, whether civil, criminal, administrative or
investigative ("proceeding"), by reason of the fact that he or
she, or a person of whom he or she is the legal representative,
is or was a Director or officer of the Corporation or is or was
serving at the request of the Corporation as a Director, officer,
employee or agent of any other corporation or of a partnership,
joint venture, trust or other enterprise, including service
with respect to employee benefit plans, whether the basis of such
proceeding is alleged action in an official capacity as a Director,
officer, employee or agent or in any other capacity while serving
as a Director, officer, employee or agent, shall be indemnified
and held harmless by the Corporation to the fullest extent
authorized by the Delaware General Corporation Law, as the
same exists or may hereafter be amended, (but, in the case of
any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification
rights than said Law permitted the Corporation to provide prior
to such amendment) against all expenses, liability and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes
or penalties and amounts paid or to be paid in settlement)
reasonably incurred or suffered by such person in connection
therewith; provided, however, that the Corporation shall indemnify
any such person seeking indemnity in connection with an action,
suit or proceeding (or part thereof) initiated by such person
only if such action, suit or proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation.  Such
right shall be a contract right and shall include the right to
be paid by the Corporation expenses incurred in defending any
such proceeding in advance of its final disposition; provided,
however, that, the payment of such expense incurred by a
Director or officer in his or her capacity as a Director or
officer (and not in any other capacity in which service was
or is rendered by such person while a Director or officer,
including, without limitation, service to an employee
benefit plan) in advance of the final disposition of such
proceeding, shall be made only upon delivery to the Corporation
of an undertaking, by or on behalf of such Director or officer,
to repay all amounts so advanced if it should be determined
ultimately that such Director or officer is not entitled to
be indemnified under this Section or otherwise.

    (b)  If a claim under paragraph (a) is not paid in full
by the Corporation within 90 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 and, if successful in whole or in
part, the claimant shall be entitled to be paid also the expense
of prosecuting such claim.  It shall be a defense to any such
action (other than an action brought to enforce a claim for
expenses incurred in defending any proceeding  in advance of
its final disposition where the required undertaking has been
tendered to the Corporation) that the claimant has not met the
standards of conduct which make it permissible under the
Delaware General Corporation Law for the Corporation to
indemnify the claimant for the amount claimed, but the
burden of proving such defense shall be on the Corporation.
Neither the failure of the Corporation (including its Board
of Directors, independent legal counsel, or it stockholders)
to have made a determination prior to the commencement of
such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable
standard of conduct set forth in the Delaware General
Corporation Law, or an actual determination by the Corporation
(including its Board of Directors, independent legal counsel,
or its stockholders) that the claimant had not met such applicable
standard of conduct, shall be a defense to the action or create a
presumption that claimant had not met the applicable standard of
conduct.

    (c)  The rights conferred on any person by paragraphs
(a) and (b) shall not be exclusive of any other right which
such person may have or hereafter acquire under any statute,
provision of the Certificate of Incorporation, Bylaw, agreement,
vote of stockholders or disinterested Directors or otherwise.

    (d)  The Corporation may maintain insurance, at its expense,
to protect itself and any such Director, officer, employee or
agent of the Corporation or another corporation, partnership,
joint venture, trust or other enterprise against any such
expense, liability or loss, whether or not the Corporation
would have the power to indemnify such person against such
expense, liability or loss under the Delaware General Corporation
Law.

                    COMMITTEES OF DIRECTORS

    17. The Board of Directors may, by resolution or resolutions
passed by a majority of the whole Board, designate one or more
committees, each committee to consist of two or more of the
Directors of the Corporation, which, to the extent provided
in said resolution or resolutions, shall have and may exercise
the powers of the Board of Directors in the management of the
business and affairs of the Corporation, and may have power to
authorize the seal of the Corporation to be affixed to all papers
which may require it.  Such committee or committees shall have
such name or names as may be determined from time to time by
resolution adopted by the Board of Directors.

    18. The committees shall keep regular minutes of their
proceedings and report the same to the Board when required.

                    COMPENSATION OF DIRECTORS

preclude any Director from serving the Corporation in any other
capacity and receiving compensation therefor.

like compensation for attending committee meetings.

to constitute the meeting; provided, a quorum shall be present; or
they may meet at such place and time as shall be fixed by the
consent in writing of all the Directors.

    22. Regular meetings of the Board may be held without notice

    24. At all meetings of the Board, three of the Directors shall
be necessary and sufficient to constitute a quorum for the

present at any meeting at which there is a quorum, shall be the act
of the Board of Directors, except as may be otherwise specifically
provided by statute or by the Certificate of Incorporation or by
these Bylaws.

or exchange of capital stock, and in such case such stockholders,
and only such stockholders as shall be stockholders of record on

that may be made against it on account of the alleged loss,
theft or destruction of any such certificate.  A new

discretion, think proper as a reserve fund to meet contingencies,
or for equalizing dividends, or for repairing or maintaining any
property of the Corporation, or for such other purpose as the
Directors shall think conducive to the interests of the
Corporation, and the Directors may abolish any such reserve in
the manner in which it was created.

required to be given to any Director, officer or stockholder, it
shall not be construed to mean personal notice, but such notices
may be given in writing, by mail, by depositing the same in the
post office or letter box, in a post-paid sealed wrapper,
