                                  ------------

                  Section 1.01. Annual Meeting. The Board of Directors by
                                --------------
resolution shall designate the time, place and date (which shall be, in the case
of the first annual meeting, not more than 13 months after the organization of
the Corporation and, in the case of all other annual meetings, not more than 13
months after the date of the last annual meeting) of the annual meeting of the
stockholders for the election of directors and the transaction of such other
business as may come before it.

                  Section 1.02. Special Meetings. Special meetings of the
                                ----------------
stockholders, for any purpose or purposes, may be called at any time by the
Chairman, the Vice-Chairman, the President, any Vice-President, the Treasurer or
the Secretary or by resolution of the Board of Directors and shall be called by
the Secretary upon receipt by the Secretary of a request to the Corporation in
writing signed by the holders of at least 35% of the Common Stock of the
Corporation then outstanding. Special meetings of stockholders shall be held at
such place, within or without the State of Delaware, as shall be fixed by the
person or persons calling the meeting and stated in the notice or waiver of
notice of the meeting.

                  Section 1.03. Notice of Meetings of Stockholders. Whenever
                                ----------------------------------
stockholders are required or permitted to take any action at a meeting, written
notice of the meeting shall be given (unless that notice shall be waived or
unless the meeting is to be dispensed with in accordance with the provisions of
the General Corporation Law of the State of Delaware) which shall state the
place, date and hour of the meeting and, in the case of a special meeting, the
purpose or purposes for which the meeting is called. The written notice of any
meeting shall be given, personally or by mail, not less than ten nor more than
sixty days before the date of the meeting to each stockholder entitled to vote
at such meeting. If mailed, such notice is given when mail, postage prepaid,
directed to the stockholder at his address as it appears on the records of the
Corporation.

                  When a meeting is adjourned to another time or place, notice
need not be given of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken. At the adjourned
meeting the Corporation may transact any business which might have been
transacted at the original meeting. If the adjournment is for more than thirty
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.

                  Section 1.04. Quorum. At all meetings of the stockholders, the
                                ------
holders of one-third of the stock issued and outstanding and entitled to vote
thereat, present in person or by proxy, shall constitute a quorum for the
transaction of any business.

                  When a quorum is once present to organize a meeting, it is not
broken by the subsequent withdrawal of any stockholders.

                  The stockholders present may adjourn the meeting despite the
absence of a quorum and at any such adjourned meeting at which the requisite
amount of voting stock shall be represented, the Corporation may transact any
business which might have been transacted at the original meeting had a quorum
been there present.

                  Section 1.05. Method of Voting. The vote upon any question
                                ----------------
before the meeting need not be by ballot. All elections and all other questions
shall be decided by a plurality of the votes cast, at a meeting at which a
quorum is present, except as expressly provided otherwise by the General
Corporation Law of the State of Delaware or the Certificate of Incorporation.

                  Section 1.06. Voting Rights of Stockholders and Proxies. Each
                                -----------------------------------------
stockholder of record entitled to vote in accordance with the laws of the State
of Delaware, the Certificate of Incorporation or these By-Laws, shall at every
meeting of the stockholders be entitled to one vote in person or by proxy for
each share of stock entitled to vote standing in his name on the books of the
Corporation, but no proxy shall be voted on after three years from its date,
unless the proxy provides for a longer period.

                  Section 1.07. Ownership of its Own Stock. Shares of its own
                                --------------------------
capital stock belonging to the Corporation or to another corporation, if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held, directly or indirectly, by the Corporation, shall
neither be entitled to vote nor be counted for quorum purposes. Nothing in this
section shall be construed as limiting the right of any corporation to vote
stock, including but not limited to its own stock, held by it in a fiduciary
capacity.

                  Section 1.08. Voting by Fiduciaries and Pledgors. Persons
v                               ----------------------------------
holding stock in a fiduciary capacity shall be entitled to vote the shares so
held. Persons whose stock is pledged shall be entitled to vote, 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 such stock and vote thereon.

                  If shares or other securities having voting power stand of
record in the names of two or more persons, whether fiduciaries, members of a
partnership, joint tenants, tenants in common, tenants by the entirety or
otherwise, or if two or more persons have the same fiduciary relationship
respecting the same shares, unless the Secretary of the Corporation is given
written notice to the contrary and is furnished with a copy of the instrument or
order appointing them or creating the relationship wherein it is so provided,
their acts with respect to voting shall have the following effect:

                                        2




                  (1) If only one votes, his act binds all;

                  (2) If more than one vote, the act of the majority so voting
binds all;

                  (3) If more than one vote, but the vote is evenly split on any
particular matter, each faction may vote the securities in question
proportionally, or any person voting the shares, or a beneficiary, if any, may
apply to the Court of Chancery or such other court as may have jurisdiction to
appoint an additional person to act with the persons so voting the shares, which
shall then be voted as determined by a majority of such persons and the person
appointed by the Court. If the instrument so filed shows that any such tenancy
is held in unequal interests, a majority or even-split for the purpose of this
subsection shall be a majority or even-split in interest.

                  Section 1.09. Fixing Date for Determination of Stockholders of
                                ------------------------------------------------
Record. In order to determine the stockholders (i) entitled to notice of or to
- ------
vote at any meeting of stockholders or any adjournment thereof, or (ii) entitled
to express consent to corporate action in writing without a meeting, or (iii)
entitled to receive payment of any dividend or other distribution or allotment
of any rights, or (iv) entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or (v) 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 nor less than ten days before the date of such meeting,
nor more than sixty days prior to any other action. If no record date is fixed
by the Board of Directors, the record date shall be determined in accordance
with the provisions of the General Corporation Law of the State of Delaware.

                  Section 1.10. List of Stockholders. The officer who has charge
                                --------------------
of the stock ledger of the Corporation shall prepare and make, at least ten days
before every meeting of the stockholders, a complete list of the stockholders
entitled to vote at the meeting, arranged in alphabetical order, and showing the
address of each stockholder and the number of shares registered in the name of
each stockholder. 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 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 said meeting
is to be held), and the list shall 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 may be present. Upon the willful neglect or refusal of the
directors to produce such a list at any meeting for the election of directors,
they shall be ineligible for election to any office at such meeting.

                  Section 1.11. Stockholder's Right of Inspection. Stockholders
                                ---------------------------------
of record, in person or by attorney or other agent, shall have the right, upon
written demand under oath stating the purpose thereof, during the usual hours
for business to inspect for any proper purpose the Corporation's stock ledger, a
list of its stockholders, and its other books and records, and to make copies or
extracts therefrom. A proper purpose shall mean a purpose reasonably related to
such person's interest as a stockholder. In every instance where an attorney or
other agent shall be the person who seeks the right to inspection, the demand
under oath shall be accompanied by a power of attorney or other writing which
authorizes the attorney or other agent to so act on

                                        3



behalf of the stockholder. The demand under oath shall be directed to the
Corporation at its registered office in this State or at its principal place of
business.

                  The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list required by Section
1.10 or the books of the Corporation, or to vote in person or by proxy at any
meeting of the stockholders.

                                   ARTICLE II.

Corporation shall be managed by its Board of Directors.

                  The Board of Directors, in addition to the powers and
authority expressly conferred upon it herein, by statute, by the Certificate of
Incorporation of the Corporation or otherwise, is hereby empowered to exercise
all such powers as may be exercised by the Corporation, except as expressly
provided otherwise by the statutes of the State of Delaware, by the Certificate
of Incorporation of the Corporation or by these By-Laws.

                  Without prejudice to the generality of the foregoing, the
Board of Directors, by resolution or resolutions, may create and issue, whether
or not in connection with the issue and sale of any shares of stock or other
securities of the Corporation, rights or options entitling the holders thereof
to purchase from the Corporation any shares of its capital stock of any class or
classes or any other securities of the Corporation, such rights or options to be
evidenced by or in such instrument or instruments as shall be approved by the
Board of Directors. The terms upon which, including the time or times, which may
be limited or unlimited in duration, at or within which, and the price or prices
at which, any such rights or options may be issued and any such shares or other
securities may be purchased from the Corporation upon the exercise of any such
right or option shall be such as shall be fixed and stated in the resolution or
resolutions adopted by the Board of Directors providing for the creation and
issue of such rights or options, and, in every case, set forth or incorporated
by reference in the instrument or instruments evidencing such rights or options.
In the absence of actual fraud in the transaction, the judgment of the directors
as to the consideration for the issuance of such rights or options and the
sufficiency thereof shall be conclusive. In case the shares of stock of the
Corporation to be issued upon the exercise of such rights or options shall be
shares having a par value, the price or prices so to be received therefor shall
not be less than the par value thereof. In case the shares of stock so to be
issued shall be shares of stock without par value, the consideration therefor
shall be determined in the manner provided in Section 153 of the General
Corporation Law of the State of Delaware.

                                ----------------
new certificate of stock in the place of any certificate theretofore issued by
it, alleged to have been lost, stolen or destroyed, if the owner: (1) so
requests before the Corporation has notice that the shares of stock represented
by that certificate have been acquired by a bona fide purchaser; (2) files with
the Corporation a bond sufficient (in the judgment of the directors) or with
respect to institutional investors an agreement, to indemnify the Corporation
against any claim that may be made against it on account of the alleged loss or
theft of that certificate or the issuance of a new certificate; and (3)
satisfies any other requirements imposed by the directors that are reasonable
