Directors, the directors present thereat may adjourn the meeting from time to

members present at any meeting and not disqualified from voting, whether or not
such member or members constitute a quorum, may unanimously appoint another
member of the Board of Directors to act at the meeting in the place of any such
absent or disqualified member. Any such committee,

of the certificate that the corporation shall issue to represent such class or
series of stock, a statement that the corporation will furnish without charge to
each stockholder who so requests the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof and the qualifications, limitations or restrictions of such
preferences and/or rights.

               SECTION 2. Any of or all the signatures on the certificate may be
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent or registrar before such certificate is
issued, it may be issued by the corporation with the same effect as if he/she
were such officer, transfer agent or registrar at the date of issue.

certificates to be issued in place of any certificate or certificates
theretofore issued by the corporation alleged to have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, stolen or destroyed. When authorizing such
issue of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his/her
legal representative, to advertise the same in such manner as it shall require
and/or to give the corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

                                TRANSFER OF STOCK

               SECTION 4. Upon surrender to the corporation or the transfer
agent of the corporation of a certificate for shares duly endorsed or

the person entitled thereto, cancel the old certificate and record the
transaction upon its books.

                               FIXING RECORD DATE

               SECTION 5. In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty (60) nor less than ten (10) days before the
date of such meeting. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; provided, however, that the Board of Directors may fix a new
record date for the adjourned meeting.

assessments a person registered on its books as the owner of shares and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                 INDEMNIFICATION

               SECTION 1. 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
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of which he or she is the 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, fiduciary or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, shall be indemnified and
held harmless by the corporation to the fullest extent which it is empowered to
do so unless prohibited from doing so by the General Corporation Law of
Delaware, as the same exists or may hereafter be


                                      -18-

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 expense, liability and loss including attorneys' fees actually and
reasonably incurred by such person in connection with such proceeding, and such
indemnification shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that the corporation shall indemnify any such
person seeking indemnification in connection with a proceeding initiated by such
person only if such proceeding was authorized by the board of directors of the
corporation. The right to indemnification conferred in this Article VIII shall
be a contract right and shall include the right to require the corporation, from
time to time, to advance any necessary and reasonable amounts for the
preparation and/or conduct of the defense incurred in defending any such
proceeding in advance of its final disposition unless otherwise determined by
the board of directors in the specific case and upon receipt of an undertaking
by or on behalf of the director or officer to repay such amount if it shall be
ultimately determined that he or she is not entitled to be indemnified by the
corporation. The corporation may, by action of its board of directors, provide
indemnification to employees and agents of the corporation with the same scope
and effect as the foregoing indemnification of directors and officers.

               SECTION 2. The rights to indemnification and the payment of
expenses incurred in defending a proceeding in advance of its final disposition
conferred in this Article VIII shall not be exclusive of any other right which
any 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.

employee, fiduciary, or agent of the corporation or was serving at the request
of the corporation as a director, officer, employee, fiduciary or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against him or her and incurred by him or her in
any such capacity, whether or not the corporation would have the power to
indemnify such person against such liability under this Article VIII.

               SECTION 4. Persons who are not covered by the foregoing
provisions of this Article VIII and who are or were employees, fiduciaries or
agents of the corporation, or who are or were serving at the request of the
corporation as directors, officers, employees, fiduciaries or agents of another
corporation, partnership, joint venture, trust or other enterprise, may be
indemnified to the extent authorized at any time or from time to time by the
board of directors.

               SECTION 5. The provisions of this Article VIII shall be deemed to
be a contract right between the corporation and each director or officer who
serves in any such capacity at any time while this Article VIII and the relevant
provisions of the General Corporation Law of Delaware or other applicable law
are in effect, and any repeal or modification of this Article VIII or any such
law shall not affect any rights or obligations then existing with respect to any
state of facts or proceeding then existing.

               SECTION 1. These bylaws may be altered, amended or repealed or
new bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the certificate of
incorporation, at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal or adoption of new
bylaws be contained in the notice of such special meeting. If the power to
adopt, amend or repeal bylaws is conferred upon the Board of Directors by the
certificate or incorporation it shall not divest or limit the power of the
stockholders to adopt, amend or repeal bylaws.
