from any increase in the authorized number of directors may be filled by a

qualified, or until their earlier resignation or removal.

committees, which committees shall, to the extent provided in the resolution of
the Board of Directors establishing such a committee, have all authority and may
exercise all the powers of the Board of Directors in the management of the
business and affairs of the Corporation to the extent lawful under the Delaware
General Corporation Law.


                                                                               3

     Section 4. Duties and Powers. The business of the Corporation shall be
managed by or under the direction of the Board of Directors which may exercise
all such powers of the Corporation and do all such lawful acts and things as are
not by statute or by the Certificate of Incorporation or by these bylaws
directed or required to be exercised or done by the stockholders.

     Section 5. Meetings. The Board of Directors of the Corporation may hold
meetings, both regular and special, either within or without the State of
Delaware. Regular meetings of the Board of Directors shall be held at such times
and places as may from time to time be fixed by the Board of Directors or as may

provided by law, the Certificate of Incorporation or these bylaws, at all
meetings of the Board of Directors, a majority of the entire Board of Directors
shall constitute a quorum for the transaction of business, and the act of a
majority of the entire Board of Directors shall be the act of the Board of
Directors. If a quorum shall not be present at any meeting of the Board of
Directors, the directors present thereat may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.

     Section 7. Actions of Board. Unless otherwise provided by the Certificate
of Incorporation or these bylaws, any action required or permitted to be taken
at any meeting of the Board of Directors or of any committee thereof may be
taken without a meeting if all the members of the Board of Directors or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board of Directors or
committee.

     Section 8. Compensation. The Corporation shall reimburse the reasonable
expenses incurred by members of the Board of Directors in connection with
attendance at meetings of the Board of Directors and of any committee on which
such member serves; provided, that the foregoing shall not preclude any director
from serving the Corporation in any other capacity and receiving compensation
therefor.

     Section 9. Removal. Unless otherwise restricted by the Certificate of
Incorporation or by law, any director or the entire Board of Directors may be
removed, with or without cause, by the holders of a majority of shares entitled
to vote at an election of directors.

     Section 10. Notices. Whenever written notice is required by law, the
Certificate of Incorporation or these bylaws, to be given to any director,
member of a committee or stockholder, such notice may be given by mail,
addressed to such director, member of a committee or stockholder, at his address
as it appears on the records of the Corporation, with postage thereon prepaid,
and such notice shall be deemed to be given at the time when the same shall be
deposited in the United States mail. Written notice may also be given personally
or by telegram, telex or cable.

     Section 11. Waivers of Notice. Whenever any notice is required by law, the
Certificate of Incorporation or these bylaws, to be given to any director,
member of a committee

                                                                               4

or stockholder, a waiver thereof in writing, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.

                                   ARTICLE IV

                                    OFFICERS

     The officers of the Corporation shall consist of a President, a Secretary,
a Treasurer and such other additional officers with such titles as the Board of
Directors shall determine, all of whom shall be chosen by and shall serve at the
pleasure of the Board of Directors. Such officers shall have the usual powers
and shall perform all the usual duties incident to their respective offices. All
officers shall be subject to the supervision and direction of the Board of
Directors. The authority, duties or responsibilities of any officer of the
Corporation may be suspended by the President with or without cause. Any officer
elected or appointed by the Board of Directors may be removed by the Board of
Directors with or without cause.

                                   ARTICLE V

     Section 1. Dividends. Dividends upon the capital stock of the Corporation,
subject to the provisions of the Certificate of Incorporation, may be declared
by the Board of Directors at any regular or special meeting, and may be paid in
cash, in property, or in shares of the capital stock. Before payment of any
dividend, there may be set aside out of any funds of the Corporation available
for dividends such sum or sums as the Board of Directors from time to time, in
its absolute discretion, deems proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the Corporation, or for any proper purpose, and the Board of
Directors may modify or abolish any such reserve.

     Section 2. Fiscal Year. The fiscal year of the Corporation shall be fixed
by the Board of Directors.


     Section 3. Corporate Seal. The corporate seal shall have inscribed thereon
the name of the Corporation, the year of its organization and the words

facsimile thereof to be impressed or affixed or in any manner reproduced.

                                                                               5


                                   ARTICLE VI

                                 INDEMNIFICATION

     Section 1. Power to Indemnify in Actions, Suits or Proceedings Other than
by or in the Right of the Corporation. Subject to Section 4 of this Article VI,
to the fullest extent permitted by the Delaware General Corporation Law, the
Corporation shall indemnify any 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 (other than
an action by or in the right of the Corporation) by reason of the fact that he
is or 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 actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     Section 2. Power to Indemnify in Actions, Suits or Proceedings by or in the
Right of the Corporation. Subject to Section 4 of this Article VI, the
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Corporation to procure a judgment in its favor by reason of the
fact that he is or 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)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation; except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for gross negligence or willful misconduct to the Corporation unless and
only to the extent that the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the court shall deem proper.

     Section 3. Costs; Charges and Expenses. Notwithstanding the other
provisions of this Article VI, to the extent that a director, officer, employee
or agent of the Corporation has been successful on the merits or otherwise,
including without limitation, the dismissal of an action without prejudice, in
the defense of any action, suit or proceeding referred to in Sections 1 and 2
above, or in the defense of any claim, issue or matter therein, that person
shall be indemnified against all costs, charges and expenses (including
attorneys' fees) actually and reasonably incurred by that person or on that
person's behalf in connection therewith.

                                                                               6

     Section 4. Authorization of Indemnification. Any indemnification under this
Article VI (unless ordered by a court) shall be made by the Corporation unless a
determination is made (i) by the Board of Directors by a majority vote of a
quorum consisting of directors who were not parties to such action, suit or
proceeding, or (ii) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion or (iii) by the stockholders, that indemnification of the
director, officer, employee or agent is not proper because that person has not
met the applicable standards of conduct set forth in Sections 1 and 2 above.

     Section 5. Good Faith Defined. For purposes of any determination under this
Article VI, a person shall be deemed to have acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation, or, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe his conduct was unlawful, if his action is based
on the records or books of account of this Corporation or another enterprise, or
on information supplied to him by the officers of the Corporation or another
enterprise in the course of their duties, or on the advice of legal counsel for
the Corporation or another enterprise or on information or record given or
reports made to the Corporation or another enterprise by an independent
certified public accountant or by an appraiser or other expert selected with
reasonable care by the Corporation or another enterprise. The term "another
enterprise" as used in this Section 5 shall mean any other corporation or any
partnership, joint venture, trust or other enterprise of which such person is or
was serving at the request of the Corporation as a Director, officer, employee
or agent. The provisions of this Section 5 shall not be deemed to be exclusive
or to limit in any way the circumstances in which a person may be deemed to have
met the applicable standard of conduct set forth in Sections 1 and 2 of this
Article VI, as the case may be.

     Section 6. Indemnification by a Court. Notwithstanding any contrary
determination in the specific case under Section 4 of this Article VI, and
notwithstanding the absence of any determination thereunder, any director,
officer, employee or agent may apply to any court of competent jurisdiction in
the State of Delaware for indemnification to the extent otherwise permissible
under Sections 1 and 2 of this Article VI. The basis of such indemnification by
a court shall be a determination by such court that indemnification of the
director, officer, employee or agent is proper in the circumstances because he
has met the applicable standards of conduct set forth in Sections 1 and 2 of
this Article VI, as the case may be. Notice of any application for
indemnification pursuant to this Section 6 shall be given to the Corporation
promptly upon the filing of such application.

     Section 7. Advance of Costs, Charges and Expenses. Costs, charges and
expenses (including attorneys' fees) incurred by a person referred to in
Sections 1 and 2 above in defending a civil or criminal action, suit or
proceeding (including investigations by any government agency and all costs,
charges and expenses incurred in preparing for any threatened action, suit or
proceeding) shall be paid by the Corporation in advance of the final disposition
of such action, suit or proceeding; provided, however, that the payment of such
costs, charges and expenses incurred by a director or officer in that person's
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) in
advance of the final disposition of such action, suit or proceeding shall be
made only upon receipt of an undertaking by or on behalf of the director or
officer to repay all amounts so

                                                                               7

advanced in the event that it shall ultimately be determined as provided
elsewhere in this Article VI that such director or officer is not entitled to be
indemnified by the Corporation as authorized in this Article VI. No security
shall be required for such undertaking and such undertaking shall be accepted
without reference to the recipient's financial ability to make repayment. The
repayment of such charges and expenses incurred by other employees and agents of
the Corporation which are paid by the Corporation in advance of the final
disposition of such action, suit or proceeding as permitted by this Section 7
may be required upon such terms and conditions, if any, as the Board of
Directors deems appropriate. The Board of Directors may, in the manner set forth
above, and subject to the approval of such director, officer, employee or agent
of the Corporation, authorize the Corporation's counsel to represent such person
in any action, suit or proceeding, whether or not the Corporation is party to
such action, suit or proceeding.

     Section 8. Procedure for Indemnification. Any indemnification under
Sections 1, 2 or 3 or advance of costs, charges and expenses under Section 7 of
this Article VI shall be made promptly, and in any event, within sixty (60)
days, upon the written request of the director, officer, employee or agent
directed to the Secretary of the Corporation. The right to indemnification or
advances granted in this Article VI shall be enforceable by the director,
officer, employee or agent in any court of competent jurisdiction if the
Corporation denies such request, in whole or part, or if no disposition thereof
is made within sixty (60) days. Such person's costs and expenses incurred in
connection with successfully establishing that person's right to indemnification
or advances, in whole or in part, in any such action shall also be indemnified
by the Corporation. It shall be a defense to any such action (other than an
action brought to enforce a claim for advance costs, charges and expenses under
Section 7 of this Article VI where the required undertaking, if any, has been
received by the Corporation) that the claimant has not met the standard of
conduct set forth in Sections 1 or 2 of this Article VI, but the burden of
proving such standard of conduct has not been met shall be on the Corporation.
Neither the failure of the Corporation (including its Board of Directors, its
independent legal counsel and its stockholders) to have made such a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he has met the applicable
standard of conduct set forth in Sections 1 and 2 of this Article VI, nor the
fact that there has been an actual determination by the Corporation (including
its Board of Directors, its independent legal counsel and its stockholders) that
the claimant has not met such applicable standard, shall be a defense to the
action or create a presumption that the claimant has not met the applicable
standard of conduct.

     Section 9. Non-Exclusivity of Indemnification and Advancement of Expenses.
The indemnification and advancement of expenses provided by or granted pursuant
to this Article VI shall not be deemed exclusive of any other rights to which
those seeking indemnification or advancement of expenses may be entitled under
any bylaw, agreement, contract, vote of stockholders or disinterested directors
or pursuant to the direction (howsoever embodied) of any court of competent
jurisdiction or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, it being the policy of the
Corporation that indemnification of the persons specified in Sections 1 and 2 of
this Article VI shall be made to the fullest extent permitted by law. The
provisions of this Article VI shall not be deemed to preclude the
indemnification of any person who is not specified in Sections 1 or 2

                                                                               8

of this Article VI but whom the Corporation has the power or obligation to
indemnify under the provisions of the Delaware General Corporation Law, or
otherwise.

     Section 10. Insurance. The Corporation may purchase and maintain insurance
on behalf of any person who is or 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 any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the Corporation would have the power or the obligation to
indemnify him against such liability under the provisions of this Article VI.

     Section 11. Meaning of "Corporation" for Purposes of Article VI. For
purposes of this Article VI, references to the "Corporation" shall include, in
addition to the resulting corporation, any constituent corporation (including
any constituent of a constituent) absorbed in a consolidation or merger which,
if its separate existence had continued, would have had the power and authority
to indemnify its directors, officers, employees or agents, so that any person
who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request for such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this Article VI with respect to the resulting
or surviving corporation as he would have with respect to such constituent
corporation if its separate existence had continued.

     Section 12. Survival of Indemnification and Advancement of Expenses. The
indemnification and advancement of expenses provided by, or granted pursuant to,
this section shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of the heirs, executors and administrators
of such a person.

                                   ARTICLE VII

                                   AMENDMENTS

     Section 1. These bylaws may be altered, amended or repealed, in whole or in
part, or new bylaws may be adopted by the majority vote of the entire Board of
Directors.

     Section 2. Entire Board of Directors. As used in this Article VII and in
these bylaws generally, the term "entire Board of Directors" means the total
number of the directors which the Corporation would have if there were no
vacancies.
