                                    BY-LAWS

                                       OF

                         4500 SERVICE CORPORATION, INC.

                                   ARTICLE I.

                          Certificate of Incorporation

    These by-laws, the powers of the corporation and of its directors and
stockholders, and all matters concerning the conduct and regulation of the
business of the corporation shall be subject to such provisions in regard
thereto as are set forth in the certificate of incorporation filed pursuant to
the General Corporation Law of Delaware which is hereby made a part of these
by-laws.

    The term "certificate of incorporation" in these by-laws, unless the
context requires otherwise, includes not only the original certificate of
incorporation filed to create the corporation but also all other certificates,
agreements of merger or consolidation, plans of reorganization, or other
instruments, howsoever designated, filed pursuant to the General Corporation
Law of Delaware which have the effect of amending or supplementing in some
respect the corporation's original certificate of incorporation.

                                  ARTICLE II.

                                 Annual Meeting

    An annual meeting of stockholders shall be held for the election of
directors and for the transaction of any other business for the transaction of
which the meeting shall have been properly convened during the month of April
in each year, on such date and at such place, within or without the State of
Delaware, and at such time as shall be fixed by the board of directors and
specified in the notice of the meeting. Any other proper business may be
transacted at the annual meeting. If the annual meeting for election of
directors shall not be held on the date designated therefor, the directors
shall cause the meeting to be held as soon thereafter as convenient.

                                  ARTICLE III.

                        Special Meetings of Stockholders

    Special meetings of the stockholders may be held either within or without
the State of Delaware, at such time and place
   2
and for such purposes as shall be specified in a call for such meeting made by
the board of directors or by a writing filed with the secretary signed by the
president or by a majority of the directors.

                                  ARTICLE IV.

                        Notice of Stockholders' Meetings

    Whenever stockholders are required or permitted to take any action at a
meeting, a written notice of the meeting shall be given 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, which notice shall be
given not less than ten nor more than fifty days before the date of the
meeting, except where longer notice is required by law, to each stockholder
entitled to vote at such meeting, by leaving such notice with him or by mailing
it, postage prepaid, directed to him at his address as it appears upon the
records of the corporation. In case of the death, absence, incapacity or
refusal of the secretary, such notice may be given by a person designated
either by the secretary or by the person or persons calling the meeting or by
the board of directors. 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.

    An affidavit of the secretary or an assistant secretary or of the transfer
agent of the corporation that the notice has been given shall, in the absence
of fraud, be prima facie evidence of the facts stated therein.

                                   ARTICLE V.

                    Quorum of Stockholders; Stockholder List

    At any meeting of the stockholders, a majority of all shares issued and
outstanding and entitled to vote upon a question to be considered at the
meeting shall constitute a quorum for the consideration of such question when
represented at such meeting by the holders thereof in person or by their duly
constituted and authorized attorney or attorneys, but a less interest may
adjourn any meeting from time to time, and the meeting may be held as
adjourned without further notice. When a quorum is present at any





                                      -2-
   3
meeting a majority of the stock so represented thereat and entitled to vote
shall, except where a larger vote is required by law, by the certificate of
incorporation or by these by-laws, decide any question brought before such
meeting.

    The secretary or other officer having charge of the stock ledger shall
prepare and make, at least ten 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 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 or town where the meeting is to be
held, which place shall have been specified in the notice of the meeting, or,
if not so specified, at the place where the meeting is to be held. Said 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 stockholders entitled
to examine the stock ledger, the list of stockholders required by this Article
or the books of the corporation, or the stockholders entitled to vote in person
or by proxy at any meeting of stockholders.

                                  ARTICLE VI.

                   Stockholder's Meetings, Proxies and Voting

    Except as otherwise provided in the certificate of incorporation, each
stockholder shall at every meeting of the stockholders be entitled to one vote
for each share of the capital stock held 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 (except as otherwise expressly permitted
by law) no proxy shall be voted or acted upon after three years from its date,
unless the proxy provides for a longer period or so long as it is coupled with
an interest sufficient in law to support an irrevocable power.

    Unless otherwise provided in the certificate of incorporation, any action
required by law to, or 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 necessary to authorize or take such action at a
meeting at which all shares entitled to vote therein were present and voted.
Prompt notice of the taking





                                      -3-

of such action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

                                  ARTICLE VII.

                           Stockholders' 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 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:

    (1)  The 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 next preceding the day on which notice is given, or, if notice is waived,
at the close of business on the day next preceding the day on which the meeting
is held.

    (2)  The record date for determining stockholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the board of directors is necessary, shall be the day on which the first
written consent is expressed.

    (3)  The record date for determining stockholders for any other purpose
shall be at the close of business on the day on which the board of directors
adopts the resolution relating thereto.

    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.

                                 ARTICLE VIII.

                               Board of Directors

    Except as otherwise provided by law or by the certificate of incorporation
or by these by-laws, the business and affairs of the corporation shall be
managed by its board of directors.



                                      -4-
   5
         The number of directors shall be such number, not fewer than one nor
more than three, as may be fixed for any corporate year and elected by the
stockholders at the annual meeting. During any year the board of directors may
be enlarged and additional directors elected to complete the enlarged number,
to not more than the maximum number above specified, by the stockholders at any
meeting or by a vote of a majority of the directors then in office. The
stockholders may, at any meeting held for the purpose during such year,
decrease, to not fewer than the minimum number above specified, the number of
directors as thus fixed or enlarged and remove directors to the decreased
number. Each director shall hold office until his successor is elected and
qualified or until his earlier resignation or removal. Any director may resign
at any time upon written notice to the corporation. No director need be a
stockholder.

                                  ARTICLE IX.

                                   Committees

    The board of directors may, by resolution passed by a majority of the whole
board, 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 and may define the number
and qualifications which shall constitute a quorum of such committee. Except as
otherwise limited by law, any such committee, to the extent provided in the
resolution appointing such committee, shall have and may exercise the powers 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. In the absence or disqualification of a member of
committee, the member or members thereof present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the board of directors to act at the
meeting in the place of any such absent or disqualified member.

                                   ARTICLE X.

              Meetings of the Board of Directors and of Committees

    Regular meetings of the board of directors may be held without call or
formal notice at such places either within or without the State of Delaware and
at such times as the board may by vote from time to time determine.

    Special meetings of the board of directors may be held at any place either
within or without the State of Delaware at any time when called by the
president, treasurer, secretary or



                                      -5-
   6
two or more directors, reasonable notice of the time and place thereof being
given to each director. A waiver of such notice in writing, signed by the
person or persons entitled to said notice, whether before or after the time
stated therein, shall be deemed equivalent to such notice. In any case it shall
be deemed sufficient notice to a director to send notice by mail at least
forty-eight hours, or to deliver personally or to send notice by telegram at
least twenty-four hours, before the meeting, addressed to him at his usual or
last known business or residence address.

    Unless otherwise restricted by the certificate of incorporation or by other
provisions of these by-laws, (a) 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 of such committee, as
the case may be, consent thereto in writing and such writing or writings are
filed with the minutes of proceedings of the board or committee, and (b)
members of the board of directors or of any committee designated by the board
may participate in a meeting thereof 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 shall constitute
presence in person at such meeting.

                                  ARTICLE XI.

                        Quorum of The Board of Directors

    Except as otherwise expressly provided in the certificate of incorporation
or in these by-laws, a majority of the total number of directors at the time in
office shall constitute a quorum for the transaction of business, but a lesser
number may adjourn any meeting from time to time. Except as otherwise so
expressly provided, the vote of a majority of the directors present at any
meeting at which a quorum is present shall be the act of the board of
directors, provided, that the affirmative vote in good faith of a majority of
the disinterested directors, even though the disinterested directors shall be
fewer than a quorum, shall be sufficient to authorize a contract or transaction
in which one or more directors have interest if the material facts as to such
interest and the relation of the interested directors to the contract or
transaction have been disclosed or are known to the directors.

                                  ARTICLE XII.

                          Waiver of Notice of Meetings

    Whenever notice is required to be given under any provision of law or the
certificate of incorporation or by-laws, a written waiver thereof, signed by
the person entitled to notice, whether before or after the time stated therein,
shall be deemed




                                      -6-
   7
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. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders, directors or members of a
committee of directors need be specified in any written waiver of notice unless
so required by the certificate of incorporation or the by-laws.

                                 ARTICLE XIII.

                              Officers and Agents

    The corporation shall have a president, secretary and treasurer, who shall
be chosen by the directors, each of whom shall hold his office until his
successor has been chosen and qualified or until his earlier resignation or
removal. The corporation may have such other officers and agents as are
desired, each of whom shall be chosen by the board of directors and shall hold
his office for such term and have such authority and duties as shall be
determined by the board of directors. The board of directors may secure the
fidelity of any or all of such officers or agents by bond or otherwise. Any
number of offices may be held by the same person. Each officer shall, subject
to these by-laws, have in addition to the duties and powers herein set forth,
such duties and powers as the board of directors shall from time to time
designate. In all cases where the duties of any officer, agent or employee are
not specifically prescribed by the by-laws, or by the board of directors, such
officer, agent or employee shall obey the orders and instructions of the
president. Any officer may resign at any time upon written notice to the
corporation.

                                  ARTICLE XIV.

                                   President

    The president shall, subject to the direction and under the supervision of
the board of directors, be the chief executive officer of the corporation and
shall have general and active control of its affairs and business and general
supervision over its officers, agents and employees. Except as otherwise voted
by the board he shall preside at all meetings of the stockholders and of the
board of directors at which he is present. The president shall have custody of
the treasurer's bond, if any.

                                  ARTICLE XX.

                                   Secretary

    The secretary shall record all the proceedings of the meetings of the
stockholders and directors in a book, which shall



                                      -7-
   8
be the property of the corporation, to be kept for that purpose; and perform
such other duties as shall be assigned to him by the board of directors. In the
absence of the secretary from any such meeting, a temporary secretary shall be
chosen, who shall record the proceedings of such meeting in the aforesaid book.

                                  ARTICLE XXI.

                                   Treasurer

    The treasurer shall, subject to the direction and under the supervision of
the board of directors, have the care and custody of the funds and valuable
papers of the corporation, except his own bond, and he shall, except as the
board of directors shall generally or in particular cases authorize the
endorsement thereof in some other manner, have power to endorse for deposit or
collection all notes, checks, drafts and other obligations for the payment of
money to the corporation or its order. He shall keep, or cause to be kept,
accurate books of account, which shall be the property of the corporation.

                                 ARTICLE XVII.

                              Voting of Securities

    As long as all of the issued and outstanding capital stock of the
corporation is owned beneficially and of record by a single entity, the
corporation shall act in respect of any securities which it owns only upon the
written instructions of such entity.

                                 ARTICLE XVIII.

                                    Removals

    The stockholders may, at any meeting called for the purpose, by vote of a
majority of the capital stock issued and outstanding and entitled to vote
thereon, remove any director from office.

    The board of directors may, at any meeting called for the purpose, by vote
of a majority of their entire number remove from office any officer or agent of
the corporation or any member of any committee appointed by the board of
directors or by any committee appointed by the board of directors or by any
officer or agent of the corporation.

                                  ARTICLE XIX.

                                   Vacancies

    Any vacancy occurring in any office of the corporation by death,
resignation, removal or otherwise and newly created


                                      -8-

directors, may be filled by a majority of the directors then in office (though

so chosen shall hold office for the unexpired term in respect of which the
vacancy occurred and until his successor shall have been duly elected and
qualified or for such shorter period as shall be specified in the filling of
such vacancy or, if such vacancy shall have occurred in the office of director,
until such a successor shall have been chosen by the stockholders.

vice-chairman of the board of directors (if one shall be incumbent) or the
president or a vice-president and by the treasurer or an assistant treasurer,
or the secretary or an assistant secretary, certifying the number of shares
owned by him in the corporation. If such certificate is countersigned (1) by a
transfer agent other than the corporation or its employee, or (2) by a
registrar other than the corporation of its employee, any other signatures on
the certificate may be facsimile. In case any officer who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer before such certificate is issued, it may be issued by the
corporation with the same effect as if he were such officer at the date of
issue.

    If the corporation shall be authorized to issue more than one class of
stock or more than one series of any class, the 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 shall be set forth in full or summarized on the
face or back of the certificates which the corporation shall issue to represent
such class or series of stock or there shall be set forth on the face or back
of the certificates which the corporation shall issue to represent such class
or series of stock, a statement that the corporation will furnish, without

stock or series thereof and the qualifications, limitations or restrictions of
such preferences and/or rights. Any restriction imposed upon the transfer of
shares or registration of transfer of shares shall be noted conspicuously on
the certificate representing the shares subject to such restriction.

destroyed, and the directors may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a

                               Board of Directors

     Except as otherwise provided by law or by the certificate of incorporation
or by these by-laws, the business and affairs of the corporation shall be
managed by its board of directors.

     The number of directors shall be such number, not fewer than one nor more
than five, as may be fixed for any corporate year and elected by the
stockholders at the annual meeting.  During any year the board of directors may
be enlarged and additional directors elected to complete the enlarged number,
to not more than the maximum number above specified, by the stockholders at any
meeting or by a vote of a majority of the directors then in office.  The
stockholders may, at any meeting held for the purpose during such year,
decrease, to not fewer than the minimum number above specified, the number of
directors as thus fixed or enlarged and remove directors to the decreased
number.  Each director shall hold office until his successor is elected and
qualified or until his earlier resignation or removal.  Any director may resign
at any time upon written notice to the corporation.  No director need by a
stockholder.
