of the corporation shall prepare and make, at least ten (10) days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each

Such list shall be open to the examination of any stockholder, for 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 specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present. The stock ledger shall be the only evidence as to who are the

entitled to vote thereat not less than ten (10) nor more than sixty (60) days
before the meeting.

         Section 2.6 Quorum. The holders of a majority of the shares of capital
stock issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at any meeting of stockholders
for the transaction of business, except as otherwise provided by statute or by
the Certificate of Incorporation. Notwithstanding the other provisions of these
bylaws, the holders of a majority of the shares of capital stock entitled to
vote thereat, present in person or represented by proxy, whether or not a quorum
is present, shall have power to adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present
or represented. If the adjournment is for more than thirty (30) days, or if
after the adjournment a 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. At such adjourned meeting at which a quorum
shall be present or represented any business may be transacted which might have
been transacted at the original meeting.

         Section 2.7 Voting. When a quorum is present at any meeting of the
stockholders, the vote of the holders of a majority of the shares of capital
stock entitled to vote thereon, present in person or represented by proxy, shall
decide any question brought before such meeting, unless the question is one upon

or of these bylaws, a different vote is required, in which case such express
provision shall govern and control the decision of such question. Every
stockholder having the right to vote shall be entitled to vote in person, or by
proxy appointed by an instrument in writing subscribed by such stockholder,
bearing a date not more than three years prior to voting, unless such instrument
provides for a longer period, and filed with the Secretary of the corporation
before, or at the time of, the meeting. If such instrument shall designate two
or more persons to act as proxies, unless such instrument shall provide to the
contrary, a majority of such persons present at any meeting at which their
powers thereunder are to be exercised shall have and may exercise all the powers
of voting or giving consents thereby conferred, or if only one be present, then
such powers may be exercised by that one, or, if an even number attend and a
majority do not agree on any particular issue, each proxy so attending shall be
entitled to exercise such powers in respect of the shares proportionately.

         Section 2.8 Consent of Stockholders. Any action required by statute to
be taken at any annual or special meeting of stockholders, or any action which
may be taken at any annual or special meeting of stockholders, may be taken
without a 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
outstanding stock having not less than the minimum number of votes that would be
required by statute, the Certificate of Incorporation or these bylaws to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted; provided, however, that 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.

         Section 2.9 Voting of Stock of Certain Holders. Shares standing in the
name of another corporation, domestic or foreign, may be voted by such officer,
agent or proxy as the bylaws of such corporation may prescribe, or in the
absence of such provision, as the Board of Directors or a duly authorized
managing director of such corporation may determine. Shares standing in the name
of a deceased person may be voted by the executor or administrator of such
deceased person, either in person or by proxy. Shares standing in the name of a
guardian, conservator or trustee may be voted by such fiduciary, either in

in such fiduciary capacity without a transfer of such shares into the name of
such fiduciary. Shares standing

   3


in the name of a receiver may be voted by such receiver. A stockholder whose
shares are pledged shall be entitled to vote such shares, unless in the transfer
by the pledgor on the books of the corporation he has expressly empowered the
pledgee to vote thereon, in which case only the pledgee, or his proxy, may
represent the stock and vote thereon.

         Section 2.10 Treasury Stock. The corporation shall not vote, directly
or indirectly, shares of its own stock owned by it; and such shares shall not be
counted in determining the total number of issued and outstanding shares for the
purposes of determining the presence of a quorum at any meeting of stockholders.

         Section 2.11 Fixing Record Date. 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 to express consent to corporate
action in writing without a meeting, 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 no more than sixty (60) days prior
to any other action, for the determination of the stockholders entitled to
notice of, and to vote at, any such meeting or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, 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. If the Board
of Directors fix, in advance, a record date as herein provided, then, in such
case, such stockholders, and only such stockholders, as shall be stockholders of
record on the date so fixed shall be entitled to such notice of, and to vote at,
any such meeting or any adjournment thereof, or to express consent to corporate
action in writing without a meeting, 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, as the case may be,
notwithstanding any transfer of any stock on the books of the corporation after
any such record date is fixed as aforesaid.

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 3.2 Number, Selection and Term. The number of directors which
shall constitute the whole Board shall from time to time be fixed and determined
by resolution adopted by the Board of Directors. The number to be elected at any
meeting of stockholders shall be set forth in the notice of any meeting of
stockholders held for such purpose. The directors shall be elected at the annual
meeting of stockholders, except as provided in Section 3.3, and each director
elected shall hold office until his successor shall be elected and shall
qualify, or until his earlier death, resignation, retirement, disqualification
or removal. Directors need not be residents of Delaware or stockholders of the
corporation.

         Section 3.3 Vacancies, Additional Directors and Removal From Office. If
any vacancy occurs in the Board of Directors caused by the death, resignation,
retirement, disqualification or removal from office of any director, or
otherwise, or if any new directorship is created by an increase in the
authorized number of directors, a majority of the

BYLAWS - 3

   4


directors then in office, though less than a quorum, or a sole remaining
director, may choose a successor to fill such vacancy or the newly created
directorship, and a director so chosen shall hold office for a term that shall
coincide with the term of the class, if any, to which such director shall have
been elected and until his successor is duly elected and qualified, or until his
earlier resignation or removal. Any director may be removed, with or without
cause, by the holders of a majority of the shares then entitled to vote at an
election of directors at any special meeting of stockholders duly called and
held for such purpose.

         Section 3.4 Resignation. Any director may resign at any time by written
notice to the corporation. Any such resignation shall take effect at the date of
receipt of such notice or at any later time specified therein, and, unless
otherwise specified therein, the acceptance of such resignation shall not be
necessary to make it effective. Any director who does not, for any reason
whatsoever, stand for election at any meeting of stockholders called for such
purpose shall be conclusively deemed to have resigned, effective as of the date
of such meeting, for the purposes of these bylaws, and the corporation need not
receive any written notice to evidence such resignation.

         Section 3.5 Regular Meeting. A regular meeting of the Board of
Directors shall be held each year, without other notice then this bylaw, at the
place of, and immediately following, the annual meeting of stockholders, and

such meeting.

         Section 3.7 Notice of Special Meeting. Written notice of special
meetings of the Board of Directors shall be given to each director at least
forty-eight (48) hours prior to the time of such meeting. Any director may waive
notice of any meeting. The attendance of a director at any meeting shall
constitute a waiver of notice of such meeting, except where a director attends a
meeting solely for the 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 special meeting of the Board of
Directors need be specified in the notice or waiver of notice of such meeting,
except that notice shall be given with respect to any matter to be acted upon at
such special meeting where notice is required by statute.

         Section 3.8 Quorum. A majority of the Board of Directors shall
constitute a quorum for the transaction of business at any meeting of the Board
of Directors, and the act of a majority of the directors present at any meeting
at which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute, by the Certificate of
Incorporation or by these bylaws. If a quorum shall not be present at any
meeting of the Board of Directors, a majority of the directors present thereat,
though less than a quorum, may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

         Section 3.9 Action Without Meeting. Unless otherwise restricted 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 as provided in Article IV of these bylaws, may be taken without a
meeting, if a written consent thereto is signed by all members of the Board or
of such committee, as the case may be, and such written consent is filed with
the minutes of proceedings of the Board or committee.

more directors as alternate members of any committee, who may replace any absent

under the provisions of any statute, the Certificate of Incorporation or these
bylaws, a waiver thereof in writing, signed by the person or persons entitled to

         Section 8.1 Insurance. Each stockholder of this corporation shall be
entitled to a certificate or certificates showing the number of shares of stock
registered in such stockholder's name on the books of the corporation. The

BYLAWS - 9

   10


or series thereof and the qualifications, limitations or restrictions of such
preferences and rights shall be set forth in full or summarized on the face or
back of the certificate which the corporation shall issue to represent such
class or series of stock; provided, however, that, except as otherwise provided
by statute, in lieu of the foregoing requirements, there may be set forth on the
face or back of the certificate which 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 a copy of 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. All certificates
surrendered to the corporation for transfer shall be canceled and no new
certificate shall be issued until the former certificate for a like number of
shares shall have been surrendered and canceled, except that in the case of a
lost, stolen, destroyed or mutilated certificate a new one may be issued
therefor upon such terms and with such indemnity, if any, to the corporation as
the Board of Directors may prescribe. Certificates shall not be issued
representing fractional shares of stock.

         Section 8.2 Lost Certificates. The corporation may issue a new
certificate or certificates 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. The corporation may in
its discretion and a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require
or to give the corporation a bond sufficient to indemnify it against any claim
that may be made against the corporation with respect to the certificate or
certificates alleged to have been lost, stolen or destroyed or the issuance of
such new certificate.

         Section 8.3 Transfers. Upon surrender to the corporation or the

transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books. Transfers of shares shall be made only on the books
of the corporation by the registered holder thereof, or by such holder's
attorney thereunto authorized by power of attorney and filed with the Secretary
of the corporation or the transfer agent.

         Section 8.4 Registered Stockholders. The corporation shall be entitled
to treat the holder of record of any share or shares of stock as the holder in

person, whether or not it shall have express or other notice thereof, except as
otherwise provided by the laws of the State of Delaware.

                                   ARTICLE IX

Incorporation.

sums as the Board of Directors from time to time, in their absolute discretion,
think proper as a reserve or reserves to meet contingencies or for equalizing
dividends, or for repairing or maintaining any

BYLAWS - 10

   11


property of the corporation, or for such other purpose as the Board of Directors
shall think conducive to the interests of the corporation, and the Directors may

                                    ARTICLE X

                                 INDEMNIFICATION

         Section 10.1 Third Party Actions. 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 such person is or was a
director, trustee, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, trustee, 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 such person
in connection with such action, suit or proceeding if such person acted in good
faith and in a manner such person 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 such person's conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contenders or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which such person 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 such
person's conduct was unlawful.

         Section 10.2 Derivative Actions. 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 the corporation's favor by reason of the
fact that such person is or was a director, trustee, officer, employee or agent
of the corporation, or is or was serving at the request of the corporation as a
director, trustee, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees) and amounts paid in settlement actually and
reasonably incurred by such person in connection with the defense or settlement
of such action or suit if such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to amounts paid in settlement, the settlement of
the suit or action was in the best interests of the corporation, provided,
however, 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 in the performance of such person's duty 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 such liability, but in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses as such court shall deem proper. The termination of any action or suit
by judgment or settlement shall not, of itself, create a presumption that the
person did not act in good faith and in a manner which such person reasonably
believed to be in or not opposed to the best interests of the corporation.

         Section 10.3 Successful Defense. To the extent that a director,
trustee, officer, employee or agent of the corporation has been successful on
the merits or otherwise, in whole or in part, in defense of any action, suit or
proceeding referred to in Sections (1) and (2) of this Article X, or in defense
of any claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection therewith.

         Section 10.4. Authorization. Any indemnification under Sections (1) and
(2) of this Article X (unless ordered by a court) shall be made by the
corporation only as authorized in the specific case upon a determination that
indemnification of the director, trustee, officer, employee or agent is proper
in the circumstances because such person has met the applicable standard of
conduct set forth above in Sections (1) and (2) of this Article X. Such
determination shall be made (a) by the Board of Directors of the corporation by
a majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding, or (b) if such a quorum is not obtainable, by a
majority vote of directors who were not parties to such action, suit or
proceeding, or (c) by independent legal counsel (selected by one or more of the
directors, whether or not a quorum and whether or not disinterested) in a
written opinion, or (d) by the shareholders. Anyone making such a determination
under this Section (4) may determine that a person has met the standard therein
set forth as to some claims, issues or matters but not as to others, and may
reasonably prorate amounts to be paid as indemnification.

         Section 10.5 Advances. Expenses incurred in defending a civil or
criminal action, suit or proceeding shall be paid by the corporation, at any
time or from time to time in advance of the final disposition of such action,
suit or proceeding as authorized in the manner provided in Section 10.4 of this
Article X upon receipt of an undertaking by or on behalf of the director,
trustee, officer, employee or agent to repay such amount unless it shall
ultimately be determined that he is entitled to be indemnified by the
corporation as authorized in this Article X.

         Section 10.6 Non-Exclusivity. The indemnification provided by this
Article X shall not be deemed exclusive of any other rights to which those
indemnified may be entitled under any law, bylaw, agreement, vote of
shareholders or disinterested directors or otherwise, both as to action in such
person's official capacity and as to action in another capacity while holding
such office, and shall continue as to a person who has ceased to be a director,
trustee, officer, employee or agent and shall inure to the benefit of the heirs,
executors, and administrators of such a person.

         Section 10.7 Insurance. The corporation shall have the powers to
purchase and maintain insurance on behalf of any person who is or was a
director, trustee, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, trustee, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against any liability asserted against such person and
incurred by such person in any such capacity or arising out of such person's
status as such, whether or not the corporation would have the power to indemnify
such person against such liability.

         Section 10.8 "Corporation" Defined. For purposes of this Article X,
references to the "corporation" shall include, in addition to the 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 power and authority to indemnify its directors,
trustees, officers, employees or agents, so that any person who is or was a
director, trustee, officer, employee or agent of such constituent corporation or
of any entity a majority of the voting stock of which is owned by such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, trustee, 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 X with respect to the
resulting or surviving corporation as such person would have with respect to
such constituent corporation if its separate existence had continued.
