contract or transaction, with like force and effect as if they were not so or
interested or connected. No ratification by stockholders of any such contract or
transaction shall be necessary to the validity thereof.



                                                                              14

more stockholders first to offer any or all of the stock of the Corporation held

way of this Corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of Section 291 of Title 8 of the Delaware Code, or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of Section 279 of Title 8 of the
Delaware Code, order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this Corporation, as the case may
be, to be summoned in such manner as the said Court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders



                                                                              16

compromise or arrangement and to any reorganization of this Corporation as a
consequence of such compromise or arrangement, the said compromise or
arrangement and the said reorganization shall, if sanctioned by the Court to
which the said application has been made, be binding on all the creditors or
class of creditors, and/or on all the stockholders or class of stockholders, of
this Corporation, as the case may be, and also on this Corporation.

or officers or former directors or officers or any person who may have served at
its request as a director or officer of another corporation in which it owns
shares of capital stock or of which it is a creditor against expenses actually
and necessarily incurred by them in connection with the defense of any action,
suit or proceeding, civil or criminal, in which they, or any of them, are made
parties, or a party, by reason of being or having been directors or officers or
a director of officer of the Corporation, or of such other corporation, except
in relation to matters as to which any such director or officer or former
director or officer or person shall be adjudged in such action, suit or
proceeding, civil or criminal, to be liable for negligence or misconduct in the
performance of duty. Such indemnification shall not be deemed exclusive of any
other rights to which those hereby indemnified may be entitled, under any
By-law,



                                                                              17

agreement, vote of stockholders or otherwise.

          TWELFTH: To the extent now or hereafter permitted by law, the
Corporation reserves the right to amend, alter, change, supplement or repeal any
provision of this Certificate of Incorporation, as from time to time amended,
