     1.   The number of directors of the corporation shall be such as from time
          to time shall be fixed by, or in the manner provided in the By-Laws.
          Election of directors need not be by ballot unless the State laws so
          provide.

     2.   The Board of Directors shall have the power without limit and without
          the assent or vote of the stockholders;

          (a)  To make, alter, amend, change, add to or repeal the ByLaws of the
               corporation; to fix and vary the amount to be reserved for any
               proper purpose; to authorize and cause there to be executed

               or net profits; and to fix the times for the declaration and
               payment of dividends.

          (b)  To determine, from time to time, whether, and to what extent, and
               at what times and places, and under what conditions and
               regulations, the accounts and books of the corporation (other
               than the stock ledger) or each of them, shall be open to the
               inspection of the shareholders.

     3.   The directors in their discretion may submit any contract or act for
          approval or ratification at any annual meeting of the stockholders
          called for the purpose of considering any such act or contract, and
          any contract or act that shall be approved or ratified by the vote of
          the holders of the majority of the stock of the corporation which is
          represented in person or by proxy at such meeting and entitled to vote
          thereat (provided that a lawful quorum of stockholders be represented
          in person or by proxy) shall be as valid and as binding upon the
          corporation and upon all the stockholders as though it had been
          approved or ratified by every stockholder of the corporation, whether
          or not the contract or act would otherwise be open to legal attack
          because of the directors' interest, or for any other reason.

     4.   In addition to the powers and authorities hereinbefore or by statute
          expressly conferred upon them, the directors are hereby empowered to
          exercise all such powers and do all such acts or things as may be

          provisions of the statutes of Delaware, of this certificate, and to
          any By-Laws from time to time made by the shareholders; provided,
          however, that no By-Laws so made shall invalidate any prior act of the
          directors which would have been valid if such By-Law had not been
          made.

     SEVENTH: The corporation shall, to the full extent permitted by Section 145
of the Delaware General Corporation Law, as amended from time to time, indemnify
all persons whom it may indemnify pursuant thereto.

                                        4

     EIGHTH: Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and any of its stockholders or any class of them, any court of
equitable jurisdiction within the State of Delaware may, on the application in a
summary 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 or class of stockholders of this
corporation, as the case may be, agree to any 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 of this
corporation.

     NINTH: The corporation reserves the right to amend, alter, repeal or change
any provision contained in this certificate of incorporation in the manner now
or hereafter prescribed by law, and all rights and powers conferred herein on
stockholders, directors and officers are subject to this reserved power.
