                                   ARTICLE I


                           MEETINGS OF STOCKHOLDERS


     Section 1.  Place of Meetings.  All meetings of the stockholders shall be
                 -----------------
held at such place within or without the State of Delaware as may be fixed from
time to time by the Board of Directors or the Chief Executive Officer, or if not
so designated, at the registered office of the corporation.


     Section 2.  Annual Meeting.  Annual meetings of stockholders shall be held
                 --------------
on the second Tuesday of May in each year if not a legal holiday, and if a legal
holiday, then on the next secular day following, at 10:00 a.m., or at such other
date and time as shall be designated from time to time by the Board of Directors
or the Chief Executive Officer, at which meeting the stockholders shall elect by
a plurality vote a Board of Directors and shall transact such other business as
may properly be brought before the meeting. If no annual meeting is held in
accordance with the foregoing provisions, the Board of Directors shall cause the
meeting to be held as soon thereafter as convenient, which meeting shall be
designated a special meeting in lieu of annual meeting.


     Section 3.  Special Meetings.  Special meetings of the stockholders, for
                 ----------------
any purpose or purposes, may, unless otherwise prescribed by statute or by the
certificate of incorporation, be called by the Board of Directors or the Chief
Executive Officer and shall be called by the Chief Executive Officer or
Secretary at the request in writing of any two members of the Board of
Directors, or at the request in writing of stockholders owning a majority in
amount of the entire capital stock of the Corporation issued and outstanding and
entitled to vote. Such request shall state the purpose or purposes of the
proposed meeting. Business transacted at any special meeting shall be limited to
matters relating to the purpose or purposes stated in the notice of meeting.


     Section 4.  Notice of Meetings.  Except as otherwise provided by law,
                 ------------------
written notice of each meeting of stockholders, annual or special, stating 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, shall be given not less
than ten or more than sixty (60) days before the date of the meeting, to each
stockholder entitled to vote at such meeting.


     Section 5.  Voting List.  The officer who has charge of the stock ledger 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
stockholder and the number of shares registered in the name of
<PAGE>

                                      -2-

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 (10) days prior to the meeting, either at a place within
the city or town 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.


     Section 6.  Quorum.  The holders of a majority of the stock issued and
                 ------
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business, except as otherwise provided by statute, the
certificate of incorporation or these By-Laws. Where a separate vote by a class
or classes is required, a majority of the outstanding shares of such class or
classes, present in person or represented by proxy, shall constitute a quorum
entitled to take action with respect to that vote on that matter. If no quorum
shall be present or represented at any meeting of stockholders, such meeting may
be adjourned in accordance with Section 7 hereof, until a quorum shall be
present or represented.


     Section 7.  Adjournments.  Any meeting of stockholders may be adjourned
                 ------------
from time to time to any other time and to any other place at which a meeting of
stockholders may be held under these By-Laws, which time and place shall be
announced at the meeting, by a majority of the stockholders present in person or
represented by proxy at the meeting and entitled to vote (whether or not a
quorum is present), or, if no stockholder is present or represented by proxy, by
any officer entitled to preside at or to act as Secretary of such meeting,
without notice other than announcement at the meeting. At such adjourned
meeting, any business may be transacted which might have been transacted at the
original meeting, provided that a quorum either was present at the original
meeting or is present at the adjourned 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 8.  Action at Meetings.  When a quorum is present at any meeting,
                 ------------------
the affirmative vote of the holders of a majority of the stock present in person
or represented by proxy, entitled to vote and voting on the matter (or where a
separate vote by a class or classes is required, the affirmative vote of the
majority of shares of such class or classes present in person or represented by
proxy at the meeting) shall decide any matter (other than the election of
Directors) brought before such meeting, unless the matter is one upon which by
express provision of law, the certificate of incorporation or these By-Laws, a
different vote is required, in which case such express provision shall govern
and control the decision of such matter.  The stock of holders who abstain from
voting on any matter shall be deemed not to have been voted on such matter.
Directors shall be elected by a plurality of the votes of the shares present in
person or represented by proxy at the meeting, entitled to vote and voting on
the election of Directors.

     Section 9.  Voting and Proxies.  Unless otherwise provided in the
                 ------------------
certificate of incorporation, each stockholder shall at every meeting of the
stockholders be entitled to one vote
<PAGE>

                                      -3-

for each share of capital stock having voting power held of record by such
stockholder. Each stockholder entitled to vote at a meeting of stockholders, or
to express consent or dissent to corporate action in writing without a meeting,
may authorize another person or persons to act for him by proxy, but no such
proxy shall be voted or acted upon after three years from its date, unless the
proxy provides for a longer period.

     Section 10.  Action Without Meeting.  Any action required 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 such stockholders, may be taken without a
meeting, without prior notice and without a vote, if a consent or consents in
writing, setting forth the action so taken, shall be (1) signed and dated by the
holders of outstanding stock having not less than the minimum 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 and (2) delivered to
the Corporation within sixty days of the earliest dated consent by delivery to
its registered office in the State of Delaware (in which case delivery shall be
by hand or by certified or registered mail, return receipt requested), its
principal place of business, or an officer or agent of the Corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded.  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 1.   Number, Election, Tenure and Qualification.  The number of
                  ------------------------------------------
Directors which shall constitute the whole board shall be not less than one (1)
nor more than seven (7).  Within such limit, the number of Directors shall be
determined by resolution of the Board of Directors or by the stockholders at the
annual meeting or at any special meeting of stockholders.  The Directors shall
be elected at the annual meeting or at any special meeting of the stockholders,
except as provided in Section 3 of this Article, and each director elected shall
hold office until his successor is elected and qualified, unless sooner
displaced.  Directors need not be stockholders.

     Section 2.   Enlargement.  The number of the Board of Directors may be
                  -----------
increased at any time by vote of a majority of the Directors then in office.


     Section 3.   Vacancies. Vacancies and newly created Directorships resulting
                  ---------
from any increase in the authorized number of Directors may be filled by a
majority of the Directors then in office, though less than a quorum, or by a
sole remaining director, and the Directors so chosen shall hold office until the
next annual election and until their successors are duly elected and shall
qualify, unless sooner displaced. If there are no Directors in office, then an
election of Directors may be held in the manner provided by statute. In the
event of a vacancy in the Board of Directors, the remaining Directors, except as
otherwise provided by law or these By-Laws, may exercise the powers of the full
board until the vacancy is filled.
<PAGE>

                                      -4-

     Section 4.   Resignation and Removal.  Any director may resign at any time
                  -----------------------
upon written notice to the Corporation at its principal place of business or to
the Chief Executive Officer or Secretary.  Such resignation shall be effective
upon receipt unless it is specified to be effective at some other time or upon
the happening of some other event.  Any director or the entire Board of
Directors 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, unless otherwise
specified by law or the certificate of incorporation.

     Section 5.   General Powers.  The business and affairs of the Corporation
                  --------------
shall be managed by its Board of Directors, which may exercise all 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 By-Laws directed or required to be
exercised or done by the stockholders.

     Section 6.   Chairman of the Board.  If the Board of Directors appoints a
                  ---------------------
chairman of the board, he shall, when present, preside at all meetings of the
stockholders and the Board of Directors.  He shall perform such duties and
possess such powers as are customarily vested in the office of the chairman of
the board or as may be vested in him by the Board of Directors.

     Section 7.   Place of Meetings.  The Board of Directors may hold meetings,
                  -----------------
both regular and special, either within or without the State of Delaware.

     Section 8.   Regular Meetings.  Regular meetings of the Board of Directors
                  ----------------
may be held without notice at such time and at such place as shall from time to
time be determined by the board; provided that any director who is absent when
such a determination is made shall be given prompt notice of such determination.
A regular meeting of the Board of Directors may be held without notice
immediately after and at the same place as the annual meeting of stockholders.

     Section 9.   Special Meetings.  Special meetings of the board may be called
                  ----------------
by the Chief Executive Officer, Secretary, or on the written request of two (2)

director in office. Two (2) days' notice to each director, either personally or
by telegram, cable, telecopy, commercial delivery service, telex or similar
means sent to his business or home address, or three (3) days' notice by written
notice deposited in the mail, shall be given to each director by the Secretary
or by the officer or one of the Directors calling the meeting. A notice or
waiver of notice of a meeting of the Board of Directors need not specify the
purposes of the meeting.

     Section 10.  Quorum, Action at Meeting, Adjournments.  At all meetings of
                  ---------------------------------------
the board a majority of Directors then in office, but in no event less than one
third of the entire board, shall constitute a quorum for the transaction of
business 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 law or by the certificate of
incorporation. For purposes of this section, the term "entire board" shall mean
the number of Directors last fixed by the stockholders or Directors, as the case
may be, in accordance with law and these By-Laws; provided, however, that if
less than all the number so fixed of Directors were elected, the "entire board"
shall mean the greatest number of Directors so elected to hold office at any one
<PAGE>

                                      -5-

time pursuant to such authorization. If a quorum shall not be present at any

announcement at the meeting, until a quorum shall be present.

     Section 11.  Action by Consent.  Unless otherwise restricted by the
                  -----------------
certificate of incorporation or these By-Laws, 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 members of the board 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 or committee.

     Section 12.  Telephonic Meetings.  Unless otherwise restricted by the
                  -------------------
certificate of incorporation or these By-Laws, members of the Board of Directors
or of any committee thereof may participate in a meeting of the Board of
Directors or of any committee, as the case may be, by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at the meeting.

     Section 13.  Committees.  The Board of Directors may designate one or more
                  ----------
committees, each committee to consist of one or more of the Directors of the
corporation.  The board may designate one or more Directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee.  Any such committee, 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, and may authorize the seal of the Corporation to be
affixed to all papers which may require it; but no such committee shall have the
power or authority in reference to (a) adopting, amending or repealing the By-
Laws of the Corporation or any of them or (b) approving or adopting, or
recommending to the stockholders any action or matter expressly required by law
to be submitted to stockholders for approval.  Such committee or committees
shall have such name or names as may be determined from time to time by
resolution adopted by the Board of Directors.  Each committee shall keep regular
minutes of its meetings and make such reports to the Board of Directors as the
Board of Directors may request.  Except as the Board of Directors may otherwise
determine, any committee may make rules for the conduct of its business, but
unless otherwise provided by the Directors or in such rules, its business shall
be conducted as nearly as possible in the same manner as is provided in these
By-Laws for the conduct of its business by the Board of Directors.

     Section 14.  Compensation.  Unless otherwise restricted by the certificate
                  ------------
of incorporation or these By-Laws, the Board of Directors shall have the
authority to fix from time to time the compensation of Directors.  The Directors
may be paid their expenses, if any, of attendance at each meeting of the Board
of Directors and the performance of their responsibilities as Directors and may
be paid a fixed sum for attendance at each meeting of the Board of Directors
and/or a stated salary as director.  No such payment shall preclude any director
from serving the Corporation or its parent or subsidiary corporations in any
other capacity and receiving compensation therefor.  The Board of Directors may
also allow compensation for members of special or standing committees for
service on such committees.

                                  ARTICLE III

                                   OFFICERS


     Section 1.  Enumeration.  The officers of the Corporation shall be chosen
                 -----------
by the Board of Directors and shall be a President, a Secretary and a Treasurer
and such other officers with such titles, terms of office and duties as the
Board of Directors may from time to time determine, including a Chairman of the
Board, one or more Vice-Presidents, and one or more Assistant Secretaries and
Assistant Treasurers.  If authorized by resolution of the Board of Directors,
the Chief Executive Officer may be empowered to appoint from time to time
Assistant Secretaries and Assistant Treasurers.  Any number of offices may be
held by the same person, unless the Certificate of Incorporation or these By-
Laws otherwise provide.

     Section 2.  Election.  The Board of Directors at its first meeting after
                 --------
each annual meeting of stockholders shall choose a President, a Secretary and a
Treasurer.  Other officers may be appointed by the Board of Directors at such
meeting, at any other meeting, or by written consent.

     Section 3.  Tenure.  The officers of the Corporation shall hold office
                 ------
until their successors are chosen and qualify, unless a different term is
specified in the vote choosing or appointing him, or until his earlier death,
resignation or removal.  Any officer elected or appointed by the Board of
Directors or by the Chief Executive Officer may be removed at any time, with or
without cause, by the affirmative vote of a majority of the Board of Directors
or a committee duly authorized to do so, except that any officer appointed by
the Chief Executive Officer may also be removed at any time, with or without
cause, by the Chief Executive Officer.  Any vacancy occurring in any office of
the Corporation may be filled by the Board of Directors, at its discretion.  Any
officer may resign by delivering his written resignation to the Corporation at
its principal place of business or to the Chief Executive Officer or the
Secretary.  Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

     Section 4.  President.  The President shall be the Chief Operating Officer
                 ---------
of the corporation.  He shall also be the Chief Executive Officer unless the
Board of Directors otherwise provides.  If no Chief Executive Officer shall have
been appointed by the Board of Directors, all references herein to the "Chief
Executive Officer" shall be to the President.  The President shall, unless the
Board of Directors provides otherwise in a specific instance or generally,
preside at all meetings of the stockholders and the Board of Directors, have
general and active management of the business of the Corporation and see that
all orders and resolutions of the Board of Directors are carried into effect.
The President shall execute bonds, mortgages, and other contracts requiring a
seal, under the seal of the corporation, except where required or permitted by
law to be otherwise signed and executed and except where the signing and
execution thereof shall be expressly delegated by the Board of Directors to some
other officer or agent of the corporation.

                                      -7-

     Section 5.  Vice-Presidents.  In the absence of the President or in the
                 ---------------
event of his or her inability or refusal to act, the Vice-President, or if there
be more than one Vice-President, the Vice-Presidents in the order designated by
the Board of Directors or the Chief Executive Officer (or in the absence of any
designation, then in the order determined by their tenure in office) shall
perform the duties of the President, and when so acting, shall have all the
powers of and be subject to all the restrictions upon the President.  The Vice-
Presidents shall perform such other duties and have such other powers as the
Board of Directors or the Chief Executive Officer may from time to time
prescribe.

     Section 6.  Secretary.  The Secretary shall have such powers and perform
                 ---------
such duties as are incident to the office of Secretary.  The Secretary shall
maintain a stock ledger and prepare lists of stockholders and their addresses as
required and shall be the custodian of corporate records.  The Secretary shall
attend all meetings of the Board of Directors and all meetings of the
stockholders and record all the proceedings of the meetings of the Corporation
and of the Board of Directors in a book to be kept for that purpose and shall
perform like duties for the standing committees when required.  The Secretary
shall give, or cause to be given, notice of all meetings of the Stockholders and
special meetings of the Board of Directors, and shall perform such other duties
as may be from time to time prescribed by the Board of Directors or Chief
Executive Officer, under whose supervision the Secretary shall be.  The
Secretary shall have custody of the corporate seal of the Corporation and the
Secretary, or an assistant Secretary, shall have authority to affix the same to
any instrument requiring it and when so affixed, it may be attested by his or
her signature or by the signature of such assistant Secretary.  The Board of
Directors may give general authority to any other officer to affix the seal of
the Corporation and to attest the affixing by his or her signature.

     Section 7.  Assistant Secretaries.  The assistant Secretary, or if there be
                 ---------------------
more than one, the assistant secretaries in the order determined by the Board of
Directors, the Chief Executive Officer or the Secretary (or if there be no such
determination, then in the order determined by their tenure in office), shall,
in the absence of the Secretary or in the event of his or her inability or
refusal to act, perform the duties and exercise the powers of the Secretary and
shall perform such other duties and have such other powers as the Board of
Directors, the Chief Executive Officer or the Secretary may from time to time
prescribe.  In the absence of the Secretary or any assistant Secretary at any

                                   ARTICLE V

                                INDEMNIFICATION


     Section 1.  Actions other than by or in the Right of the Corporation.  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 proceedings, 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.  Actions by or in the Right of the Corporation.  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 or she 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 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 he or
she reasonably believed to be in or not opposed to the best interests of the
Corporation and 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 unless and only to the extent that the Court of Chancery of the State of
Delaware or 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 of Chancery of the State of Delaware
or such other court shall deem proper.

     Section 3.  Success on the Merits.  To the extent that any person described
                 ---------------------
in Section 1 or 2 of this Article V has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in said
Sections, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

     Section 4.   Specific Authorization. Any indemnification under Section 1 or
                  ----------------------
2 of this Article V (unless ordered by a court) shall be made by the Corporation
only as authorized in the specific case upon a determination that
indemnification of any person described in said Sections is proper in the
circumstances because he has met the applicable standard of conduct set forth in
said Sections. Such determination shall be made (1) by the Board of Directors by
a majority vote of Directors who were not parties to such action, suit or
proceeding (even though less than a quorum), or (2) if there are no
disinterested Directors or if a majority of disinterested Directors so directs,
by independent legal counsel (who may be regular legal counsel to the
corporation) in a written opinion, or (3) by the stockholders of the
corporation.

     Section 5.   Advance Payment.  Expenses incurred in defending a pending or
                  ---------------
threatened civil or criminal action, suit or proceeding may be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of any person
described in said Section to repay such amount if it shall ultimately be
determined that he or she is not entitled to indemnification by the Corporation
as authorized in this Article V.

     Section 6.   Non-Exclusivity.  The indemnification and advancement of
                  ---------------
expenses provided by, or granted pursuant to, the other Sections of this Article
V shall not be deemed exclusive of any other rights to which those provided
indemnification or advancement of expenses may be entitled under any By-Law,
agreement, vote of stockholders or disinterested Directors or otherwise, both as
to action in his official capacity and as to action in another capacity while
holding such office.

     Section 7.   Insurance.  The Board of Directors may authorize, by a vote of
                  ---------
the majority of the full board, the Corporation to 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 to indemnify him
against such liability under the provisions of this Article V.

     Section 8.   Continuation of Indemnification and Advancement of Expenses.
                  -----------------------------------------------------------
The indemnification and advancement of expenses provided by, or granted pursuant
to, this Article V shall 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.

     Section 9.   Severability. If any word, clause or provision of this Article
                  ------------
V or any award made hereunder shall for any reason be determined to be invalid,
the provisions hereof shall not otherwise be affected thereby but shall remain
in full force and effect.

     Section 10.  Intent of Article.  The intent of this Article V is to provide
                  -----------------
for indemnification and advancement of expenses to the fullest extent permitted
by Section 145 of the General Corporation Law of Delaware.  To the extent that
such Section or any successor section may be amended or supplemented from time
to time, this Article V shall be amended
<PAGE>

                                      -11-

automatically and construed so as to permit indemnification and advancement of
expenses to the fullest extent from time to time permitted by law.


                                  ARTICLE VI

                                 CAPITAL STOCK

     Section 1.  Certificates of Stock.  Every holder of stock in the
                 ---------------------
Corporation shall be entitled to have a certificate, signed by, or in the name
of the Corporation by, the chairman or Vice-chairman of the Board of Directors,
or the President or a Vice-President and the Treasurer or an assistant
Treasurer, or the Secretary or an assistant Secretary of the corporation,
certifying the number of shares owned by such holder in the corporation.  Any or
all of the signatures on the certificate may be a facsimile.  In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the Corporation with the same effect as if he were such officer, transfer
agent or registrar at the date of issue.  Certificates may be issued for partly
paid shares and in such case upon the face or back of the certificates issued to
represent any such partly paid shares, the total amount of the consideration to
be paid therefor, and the amount paid thereon shall be specified.

     Section 2.  Lost Certificates.  The Board of Directors may direct a new
                 -----------------
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Corporation alleged to have been lost,
stolen or destroyed.  When authorizing such issue of a new certificate or
certificates, the Board of Directors may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed certificate or certificates, or his legal representative, to give
reasonable evidence of such loss, theft or destruction, to advertise the same in
such manner as it shall require and/or to give the Corporation a bond in such
sum as it may direct as indemnity against any claim that may be made against the
Corporation with respect to the certificate alleged to have been lost, stolen or
destroyed or the issuance of such new certificate.

     Section 3.  Transfer of Stock.  Upon surrender to the Corporation or the
                 -----------------
transfer agent of the Corporation of a certificate for shares, duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, and proper evidence of compliance with other conditions to rightful
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.

     Section 4.  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, the Board of Directors may fix a record date, which
shall not precede the date upon which the resolution fixing the record date is
adopted by the Board of Directors, and which shall not be more than sixty days
nor less then ten days before the date of such meeting.  A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned meeting.
If no record date is fixed, the
<PAGE>

                                      -12-

record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day before the
day on which notice is given, or, if notice is waived, at the close of business
on the day before the day on which the meeting is held. In order that the
Corporation may determine the stockholders entitled to consent to corporate
action in writing without a meeting, the Board of Directors may fix a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the Board of Directors, and which shall not be more
than ten days after the date upon which the resolution fixing the record date is
adopted by the Board of Directors. If no record date is fixed, the record date
for determining stockholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the Board of Directors is required by
statute, shall be the first date on which a signed written consent setting forth
the action taken or proposed to be taken is delivered to the Corporation as
provided in Section 10 of Article I. If no record date is fixed and prior action
by the Board of Directors is required, the record date for determining
stockholders entitled to consent to corporate action in writing without a
meeting shall be at the close of business on the date on which the Board of
Directors adopts the resolution taking such prior action. In order that the
Corporation may determine the stockholders entitled to receive payment of any
dividend or other distribution or allotment of any rights or the stockholders
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 a record date, which shall not precede the date upon which the
resolution fixing the record date is adopted, and which shall be not more than
sixty days prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating to
such purpose.

     Section 5.  Registered Stockholders.  The corporation shall be entitled to
                 -----------------------
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of
shares, and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of Delaware.

officers are Directors or officers, or have a financial interest, shall be void
