stockholders, stating the time and place of the meeting, and the purpose of any
special meeting shall be mailed to each stockholder entitled to vote at or to
notice of such meeting at the address shown on the books of the Corporation in

or consolidation or a sale, lease, exchange, or other, disposition of all or
substantially all the property and assets of the corporation is to be considered
at any annual or special meeting, the written notice shall state the purpose of
such meeting and shall be given to the stockholder, whether or not entitled to
vote thereon, not less than twenty (20) days before such meeting. Any

meeting.

         Notice of any meeting may be given by the President, the Secretary or
the person or persons calling such meeting. No notice need be given of the time
and place of reconvening of any adjourned meeting, if the time and place to
which the meeting is adjourned are announced at the adjourned meeting, unless
the adjournment is for more than thirty days.

         Section 4. List of Stockholders. The officer who has charge of the
stock ledger of the Corporation shall prepare and make, at least ten (10) days

any purpose germane to the meeting, during ordinary business hours, for a period
of at least ten (10) days prior to the meeting, either at a place within the
city where the meeting is to be held, which place shall be specific in the

transaction of business at any annual or special meeting of stockholders shall
exist when the holders of a majority of the outstanding shares entitled to vote
are represented either in person or by proxy of such meeting. If a quorum is

meeting and entitled to vote on the subject matter shall be the act of the
stockholders, unless a greater vote is required by law, by the Certificate of
Incorporation or by these Bylaws. When a quorum is once present to organize a
meeting, the stockholders present may continue to do business at the meeting or
at any adjournment thereof notwithstanding withdrawal of enough stockholders to

represented at a meeting, whether or not a quorum is present, may adjourn such
meeting from time to time.

number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted.
Prompt notice of the taking of the corporate action without a meeting by less
than unanimous written consent shall be given to those stockholders who have not
consented in writing. Such consent shall have the same force and effect as an
affirmative vote of the stockholders and shall be filed with the minutes of the
proceedings of the stockholders.

stockholders. The Board of Directors may by resolution provide for the time and
place of other regular meetings and no notice of such regular meetings need be
given. Special meetings of the Board of Directors may be called by the President
or by any two directors unless the Board consists of one director, in which case
special meetings may be called by the sole director. Written notice of the time
and place of such meetings shall be given to each director by first class or air
mail at least four (4) days before the meeting or by telephone, telegraph,
cablegram or in person at least two (2) days before the meeting. Any director
may execute a waiver of notice, either before or after any meeting, and shall be
deemed to have waived notice if he is present at such meeting. Neither the
business to be transacted at, nor the purpose of, any meeting of the Board of
Directors need be stated in the notice or waiver of notice of such meeting. Any
meeting may be held at any place within or without the State of Delaware.

         Section 4. Quorum; Vote Requirement. A majority of the number of
directors last fixed by the stockholders shall constitute a quorum for the
transaction of business at any meeting. When a quorum is present, the vote of a
majority of the directors present shall be the act of the Board of Directors,
unless a greater vote is required by law, by the Certificate of Incorporation or
by these Bylaws.

         Section 5. Action of Board without Meeting, Any action required or
permitted to be taken at a meeting of the Board of Directors or by committee
thereof may be taken without a meeting if written consent, setting forth the
action so taken, is signed by all the directors or committee members and filed
with the minutes of proceedings of the Board of Directors or committee. Such
consent shall have the same force and effect as a unanimous affirmative vote of
the Board of Directors or committee, as the case may be.

         Section 6. Committees. The Board of Directors, by resolution adopted by
a majority of all of the directors, may designate such committees as it deems
necessary or desirable, each composed of one (1) or more of the directors. Any

papers which may require it and, to the extent provided in the resolution of the
Board of Directors, shall have and may exercise all the powers and authority of
the Board of Directors in the management of the business and affairs of the
Corporation; provided that no committee shall have the authority of the Board of
Directors in reference to (1) an amendment to the Certificate of Incorporation
(except that a committee may, to the extent authorized in the resolution


                                      -3-
   4
or resolutions providing for the issuance of shares of stock adopted by The
Board of Directors as provided in Section 151(a) of the Delaware General
Corporation Law fix any of the preferences or rights of such shares relating to
dividends, redemption, dissolution, any distribution of assets of the
Corporation or the conversion into, or the exchange of such shares for, shares
of any other class or classes of any other series of the same or any other class
or classes of stock of the corporation), (2) the adoption of an agreement of
merger or consolidation, (3) the sale, lease or exchange or other disposition of
all or substantially all of the property and assets of the Corporation, (4) a
voluntary dissolution of the Corporation or a revocation thereof, or (5) an
amendment to the Bylaws of the Corporation; and, unless the resolution or the
Certificate of Incorporation expressly so provides, no such committee shall have
the power or authority to declare a dividend, to authorize the issuance of
stock, or to adopt a certificate of ownership and merger.

         Section 7. Vacancies. Any vacancy occurring in the Board of Directors
may be filled by the affirmative vote of a majority of the remaining directors
though less than a quorum of the Board of Directors or by the sole remaining
director, as the case may be, or if the vacancy is not so filled, or if no
director remains, by the stockholders. A director elected to fill a vacancy
shall serve for the unexpired term of his predecessor in office, or, if such
vacancy occurs by reason of an amendment to these Bylaws increasing the number
of directors, until the next election of directors by the stockholders and the
election and qualification of the successor.

         Section 8. Telephone Conference Meetings. Unless the Certificate of
Incorporation otherwise provides, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board or any committee by means of telephone conference or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
Section 8 shall constitute presence in person at such meeting.

elected or appointed or until such officer's successor has been elected or
appointed and has qualified, or until such officer's earlier resignation,
removal from office, or death. Any two or more officers may be held by the same

delegated to such officer, employee or agent by the President.

         Section 7. Removal of Officers. Any officer may be removed at any time
by the Board of Directors, and such a vacancy may be filled by the Board of
Directors. This provision shall not prevent the making of a contract of

removal in breach a of a contract of employment.

from time to time by the Board of Directors. No officer shall be prevented from

of the Corporation, and which shall be sealed with the seal of the Corporation.

         Within a reasonable time after the issuance or transfer of
uncertificated stock, the Corporation shall send to the registered owner thereof
a written notice containing the information required to be set forth stated on
certificates pursuant to Section 151, 156, 202(a) or 218(a) of the Delaware
General Corporation Law or a statement that the Corporation will furnish without

                                      -5-
   6
special rights of each class of stock or series thereof and the qualifications,

         Section 2. Transfer of Stock. Shares of stock of the Corporation shall
be transferred only on the books of the Corporation upon surrender to the
Corporation of the certificate or certificates representing the shares to be

than ten (10) days prior to the date on which the particular action, requiring
such determination of stockholders, is to be taken.

                                    INDEMNITY

         Section 1. 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 or
employee of the Corporation or 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 (if
serving for another corporation at the request of the Corporation) agent or in
any other capacity while serving as a director, officer, employee or (if serving
for another corporation at the request of the Corporation) agent or in any other
capacity while serving as a director, officer, employee or (if serving for
another corporation agent, shall be indemnified and held harmless by the
Corporation to the fullest extent authorized by the Delaware General Corporation
Law, as the same exists or may hereafter be 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, judgments, fines, ERISA excise taxes or
penalties and amounts to be paid in settlement) reasonably incurred or suffered
by such person in connection therewith and such indemnification shall continue
as to a person who has ceased to be a director, officer, employee or (if serving
for another corporation at the request of the Corporation) agent and shall inure
to the benefit of his or her heirs, executors: and administrators; provided,
however, that except as provided in Section 2 hereof with respect to proceedings
seeking to enforce rights to indemnification, the Corporation shall indemnify
any such persons seeking indemnification, in connection with a proceeding (or
part thereof) initiated by such person only if such proceeding (or part thereof)
was authorized by the Board of Directors of the Corporation. The right to
indemnification conferred in this Section 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 Delaware General Corporation Law 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


                                      -7-
   8
director or officer, including, without limitation, service to an employee
benefit plan) in advance of the final disposition of the 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 Article VI or otherwise.

         Section 2. Payment of Indemnification. If a claim under Section I of
this Article VI is not paid in full by the Corporation within 90 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 expense 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 in the
Corporation) that the claimant has not met the standards of conduct which make
it permissible under the Delaware General Corporation Law 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 of Directors, independent legal counsel, or stockholders)
to have made a determination prior to the commencement of such action that
indemnification of the claimant is proper in the circumstances because he or she
has met the applicable standard of conduct set forth in the Delaware General
Corporation Law, nor an actual determination by the Corporation (including its
Board of Directors, independent legal counsel, or stockholders) that the
claimant has not met such applicable standard of conduct, should be a defense to
the action or create a presumption that the claimant has not met the applicable
standard of conduct.

         Section 3. Indemnification Not Exclusive The right to indemnification
and the payment of expenses incurred in defending a proceeding in advance of its
final disposition conferred in this Article VI 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.

         Section 4 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 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 Delaware General Corporation Law.

                                   ARTICLE VII
                               AMENDMENT OF BYLAWS

         The Board of Directors shall have the power to alter, amend or repeal
the Bylaws or adopt new bylaws, but any bylaws adopted by the Board of Directors
may be altered, amended, or repealed and new bylaws adopted by the stockholders.
The stockholders may prescribe that any bylaw or bylaws adopted by them shall
not be altered amended or repealed by the Board of Directors.
