at a meeting of stockholders. If such majority shall not be present in person or

shares of stock entitled to vote at the meeting shall be present in person or
represented by proxy. When a meeting of stockholders is adjourned to another
place, date or time, notice need not be given of the adjourned meeting if the
place, date, and time of such adjourned meeting are announced at the meeting at
which the adjournment is taken. At any such adjourned meeting at which a quorum
shall be present in person or represented by proxy, stockholders may transact
any business that might have been transacted at the meeting as originally
noticed, but only those stockholders entitled to vote at the meeting as
originally noticed shall be entitled to vote at any adjournment(s) thereof. If

new record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.

capital stock present in person or represented by proxy at a meeting of
stockholders at which a quorum is present and entitled to vote on the subject
matter (including, but not limited to, the election of directors to the Board)

meeting, without prior notice, and without a vote if a consent in writing,
setting forth the action so taken, shall be signed by the holders of shares of
capital stock issued and outstanding and entitled to vote on the subject matter
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting of stockholders at which all such

if there be more than one, the Assistant Secretaries, shall perform such duties
as may be specifically assigned to them from time to time by the Board, the CEO
or the President. In case of the absence or disability of the Secretary, and if
the Board, the CEO or the President has so authorized, the Assistant Secretary,
or if there be more than one Assistant Secretary, such Assistant Secretary as
the Board, the CEO or the President shall designate, shall perform the duties of
the office of the Secretary.

                              CERTIFICATES OF STOCK

               Section 8.1. Form and Signature.

               The stock certificates representing the stock of the Corporation
shall be in such form or forms not inconsistent with the General Corporation Law
of the State of Delaware, the Certificate of Incorporation and these Bylaws as
the Board shall approve from time to time. Stock certificates shall be numbered,
the certificates for the shares of stock to be numbered consecutively, and shall
be entered in the books and records of the Corporation as such certificates are
issued. No certificate shall be issued for any share until the consideration
therefor has been fully paid. Stock certificates shall exhibit the holder's
name, certify the class and series of stock and the number of shares in such
class and series of stock owned by the holder, and shall be signed (a) by the
Chairman of the Board, or any Vice Chairman of the Board, or the CEO, or the
President, or a Vice President, and (b) by the Treasurer, or any Assistant
Treasurer, or the Secretary, or any Assistant Secretary. Any or all of the
signatures on a stock certificate may be facsimiles. In case any officer,
transfer agent, or registrar who has signed or whose facsimile signature has
been placed on a certificate shall have ceased to be such officer, transfer
agent or registrar before such certificate is issued, such certificate may be
issued by the Corporation with the same effect as if he or she were such
officer, transfer agent or 



                                       9
   10

registrar on the date of issuance.

               Section 8.2. Lost, Stolen or Destroyed Certificates.

               The Board may direct that a new stock certificate be issued in
place of any certificate theretofore issued by the Corporation which is alleged
to have been lost, stolen, or destroyed, upon the making of an affidavit of that
fact by the person, or his or her legal representative, claiming the certificate
of stock to be lost, stolen or destroyed. When authorizing such issuance of a
new certificate, the Board, in its discretion and as a condition precedent to
the issuance thereof, may require the owner of the lost, stolen or destroyed
certificate, or his or her legal representative, to advertise the same in such
manner as the Board shall require and/or to give the Corporation a bond in such
sum as the Board shall direct as indemnity against any claim that may be made
against the Corporation, any transfer agent or any registrar on account of the
alleged loss, theft, or destruction of any such certificate or the issuance of
such new certificate.

               Section 8.3. Registration of Transfer.

               Shares of common stock of the Corporation shall be transferable
only upon the Corporation's books by the holders thereof in person or by their
duly authorized attorneys or legal representatives, and upon such transfer the
old certificates shall be surrendered to the Corporation by the delivery thereof
to the person in charge of the stock and transfer books and ledgers of the
Corporation, or to such other person as the Board may designate. Upon surrender
to the Corporation of a certificate for shares, duly endorsed or accompanied by
proper evidence of succession, assignment, or authority to transfer, the
Corporation shall issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction on its books and records.


                                   ARTICLE IX

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
may fix, in advance, a record date which shall not be more than sixty (60) nor
less than ten (10) days prior to the date of such meeting nor more than sixty
(60) days prior to any other action. A determination of stockholders of record
entitled to notice of, and to vote at, a meeting of stockholders shall apply to

               Except as specifically provided otherwise by the General
Corporation Law of the State of Delaware, the Corporation shall be entitled to
recognize the exclusive right of a person registered on its books and records as
the owner of shares of stock of the Corporation to receive dividends and to vote
as such owner, shall be entitled to hold such person liable for calls and
assessments, and shall not be bound to recognize any equitable or other claim
to, or interest in, such stock on the part of any other person, whether or not
the Corporation shall have

               Section 9.3. Dividends.

acceptances, obligations, and other instruments for the payment of money drawn,
signed, or accepted by the Corporation shall be signed or accepted, as the case
may be, by such officer or officers, agent or agents, and in such manner as

the Corporation designated by the Board to make such authorization.

               In the event that the Corporation shall own and/or have power to
vote any securities (including, but not limited to, shares of stock) of any
other issuer, such securities shall be voted by the Chairman of the Board or by
such other person or persons, to such extent, and in such manner as may be
determined by the Board. If the Corporation shall be a general partner in any
partnership, the acts of the Corporation in such capacity may be approved by the
Board and taken by the officers as may be authorized or determined by the Board
from time to time.

               Section 9.9. Transfer Agents.

               Section 9.10. Books and Records.

               Except as specifically provided otherwise by the General

                                    ARTICLE X

                                 INDEMNIFICATION

               Section 10.1. Indemnification and Insurance.

               (a) Right to Indemnification. 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 whom he or she is the legal representative, is or was a director, officer,
employee or agent of the Corporation is or was serving at the request of the
Corporation as a director, officer, employee or agent of another 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 General Corporation Law of the State of Delaware, as
the same exists or may hereafter be amended, against all costs, charges,
expenses, liabilities and losses (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 as so
incurred or suffered and such indemnification shall continue as to a person who
has ceased to be a director, officer, employee or agent and shall inure to the
benefit of his or her heirs, executors and administrators. The right to
indemnification conferred in this Section 10.1 shall be a contract right and
shall include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
however, that, if the General Corporation Law of the State of Delaware requires,
the payment of such expenses 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 a 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 shall ultimately be determined that such
director or officer is not entitled to be indemnified under this Section 10.1 or
otherwise.

               (b) Right of Claimant to Bring Suit. If a claim under paragraph
(a) of this Section 10.1 is not paid in full by the Corporation within thirty
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 expenses 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, if any is required, has been
tendered to the Corporation) that the claimant has not met the standards of
conduct which make it permissible under the General Corporation Law of the State
of Delaware 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, independent legal
counsel, or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is 



                                       12
   13

proper in the circumstances because he or she has met the applicable standard of
conduct set forth in the General Corporation Law of the State of Delaware, nor
an actual determination by the Corporation (including its Board, independent
legal counsel, or its stockholders) that the claimant has not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that the claimant has not met the applicable standard of conduct.

               (c) Non-Exclusivity of Rights. The right to indemnification and
the payment of expenses incurred in defending a proceeding in advance of its
final disposition conferred in this Section 10.1 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.

               (d) Insurance. The Corporation may maintain insurance, at its
expense, to protect itself and any 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 General Corporation Law of the State of Delaware.


               (e) Witness. To the extent that any director, officer, employee
or agent of the Corporation or another corporation, partnership, joint venture,
trust or other enterprise is by reason of such position a witness in any action,
suit or proceeding, he or she shall be indemnified against all costs and
expenses actually and reasonably incurred by him or her on his or her behalf in
connection therewith.


                                   ARTICLE XI
