immediately after the Annual meeting of stockholders, and notice need not be
given of regular meetings held at times fixed by resolutions of the Board.

of the Directors not less than the time above specified before the meeting shall
be sufficient. A majority of the then authorized Directors shall constitute a
quorum for the transaction of business, and the act of a majority of the then
authorized Directors shall be the act of the Board of Directors.

express purpose of objecting to the transaction of any business because the
meeting is not lawfully called or convened. Neither the business to be
transacted at, nor the purpose of, any regular or special meeting of the Board
of Directors need be specified in the notice or waiver of notice of such
meeting.

          Section 6. A Director shall be fully protected in relying in good
faith upon the books of account of the

                                      -19-



corporation or statements prepared by any of its officials as to the value and
amount of the assets, liabilities and/or net profits of the corporation, or any
other facts pertinent to the existence and amount of surplus or other funds from
which dividends might properly be declared and paid.

                        Contracts - Interest of Director

          Section 7. No contract or other transaction between the corporation
and any other corporation and no other act of the corporation shall, in the
absence of fraud, be invalidated or in any way affected by the fact that any of
the Directors of the corporation are pecuniarily or otherwise interested in such
contract, transaction or other act, or are Directors or Officers of such other
corporation. Any Director of the corporation, individually, or any firm or
association of which any such Director may be a member, may be a party to, or
may be pecuniarily or otherwise interested in, any contract or transaction of
the corporation, provided that the fact that he individually or such firm or
association is so interested shall be disclosed or shall have been known to the
Board of Directors; and any Director of the corporation who is so interested may
be counted in determining the existence of a quorum at any meeting of the Board
of Directors which shall authorize any such contract or transaction, and may
vote thereat to authorize any such contract or transaction with like force and
effect as if he were not such Director or Officer of

                                      -20-



such other corporation or not so interested, every Director of the corporation
being hereby relieved from any disability which might otherwise prevent him from
carrying out transactions with or contracting with the corporation for the
benefit of himself or any firm, corporation, association, trust or organization
in which or with which he may be in anywise interested or connected.

          Any contract, transaction or act of the corporation or by the Board of
Directors which shall be ratified by a majority of the stockholders entitled to
vote at any annual meeting or at any special meeting called for that purpose
shall be as valid and binding as though ratified by every stockholder of the
corporation; provided, however, that any failure of the stockholders to approve
or ratify such contracts, transaction or act when and if submitted, shall not be
deemed in any way to invalidate the same or to deprive the corporation, its
Directors or Officers of their right to proceed with such contract, transaction
or action.

                    Indemnification - Directors and Officers

          Section 8. The corporation may indemnify every person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, including an action by or in the right of the corporation, by
reason of the fact that said person is or

                                      -21-



was a director, officer, employee, or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement incurred by said person in connection with such
action, suit or proceeding, to the full extent permitted by the laws of the
State of Delaware in effect from time to time. The corporation shall have the
right and power to purchase and maintain insurance in such principal amounts as
shall be approved by resolution of the Board of Directors of the corporation
from time to time on behalf of each said person against any liability asserted
against and incurred by said person in any such aforesaid capacity, or arising
out of said person's status as such, to the full extent permitted by the laws of
the State of Delaware in effect from time to time.

                                   AMENDMENTS

          These By-laws may be altered, amended or repealed or new By-laws may
be adopted at any regular or special meeting of stockholders, or of the
Directors, at which a quorum is present or represented, by the affirmative vote
of a majority of the outstanding stock entitled to vote, or of a majority of the
Directors of the corporation, provided

                                      -22-
