                                     STOCKHOLDERS
                                     ------------

                    SECTION 1.1    ANNUAL MEETINGS.  The annual meeting of
                                   ---------------
          the stockholders for the election of directors and for the
          transaction of such other business as may properly come before
          the meeting shall be held on such date as the board of directors
          shall fix each year.  Each such annual meeting shall be held at
          such date, time, and place, within or without the State of
          Delaware, as shall be determined by the board of directors.  Any
          annual meeting of stockholders may be adjourned from time to time
          and place to place until its business is completed.

                    SECTION 1.2    SPECIAL MEETINGS.  Except as otherwise
                                   ----------------
          required by law or by the certificate of incorporation and
          subject to the rights of the holders of any class or series of
          stock having a preference over the common stock as to dividends
          or on liquidation, special meetings of the stockholders may be
          called only by the chairman of the board or the president, or by
          the board of directors pursuant to a resolution approved by a
          majority of the entire board of directors.   The term "entire
          board of directors," as used in these bylaws, means the total
          number of directors which the Corporation would have if there
          were no vacancies.  A special meeting of stockholders shall be
          called by the president upon the written request, stating date,
          time, place and purpose(s) of the meeting, of stockholders who
          together own of record not less than 5% of the voting power of
          the outstanding stock of all classes entitled to vote at such
          meeting.

                    SECTION 1.3    CONSENT OF STOCKHOLDERS IN LIEU OF
                                   ----------------------------------
          MEETING.  Unless otherwise restricted by the certificate of 
          -------   
          incorporation, any action required or permitted to be taken 
          at any annual meeting or special meeting of the 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 thereon were present and voted and 
          shall be delivered to the Corporation by delivery to its 
          registered office in the State of Delaware, 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.  Any such consent may be in counterparts
          and shall be effective on the date of the last signature thereon 
          unless otherwise provided therein.  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 and who, if the action had been taken at a 
          meeting, would have been entitled to notice of the meeting if the 


     

          record date for such meeting had been the date that written 
          consents signed by a sufficient number of stockholders to take 
          the action were delivered to the Corporation as provided above.

                    SECTION 1.4    NOTICE OF MEETING.  Written notice
                                   -----------------
          stating the place, date and hour of the meeting and, in case of a
          special meeting, the purpose or purposes for which the meeting is
          called, shall be given not less than 10 nor more than 60 days
          before the date of the meeting, except as otherwise required by
          statute or the certificate of incorporation, either personally or
          by mail, prepaid telegram, telex, or facsimile transmission to
          each stockholder of record entitled to vote at such meeting.  If
          mailed, such notice shall be deemed to be given when deposited in
          the United States mail, postage prepaid, addressed to the
          stockholder at his address as it appears on the stock records of
          the Corporation.  If given personally or otherwise than by mail,
          such notice shall be deemed to be given when either handed to the
          stockholder or delivered to the stockholder's address as it
          appears on the stock records of the Corporation.  The Corporation
          shall, at the written request of any stockholder, cause such
          notice to such stockholder to be confirmed to another address
          and/or by such other means as such stockholder may reasonably
          request, provided that if a written request is received after the
          date any such notice is mailed, such request shall be effective
          for subsequent notices only.

                    SECTION 1.5    WAIVER.  Attendance of a stockholder of
                                   ------
          the Corporation, either in person or by proxy, at any meeting,
          whether annual or special, shall constitute a waiver of notice of
          such meeting, except where a stockholder 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.  A written waiver of notice
          of any such meeting signed by a stockholder or stockholders
          entitled to such notice, whether before, at or after the time for
          notice or the time of the meeting, shall be equivalent to notice. 
          Neither the business to be transacted at, nor the purposes of,
          any meeting need be specified in any written waiver of notice.

                    SECTION 1.6    LIST OF STOCKHOLDERS ENTITLED TO VOTE.
                                   -------------------------------------
          The secretary shall prepare and make available, at least 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 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 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 be produced and kept at the place of the meeting
          during the whole time thereof and may be inspected by any
          stockholder who is present.

                    SECTION 1.7    QUORUM; ADJOURNMENT.  Except as
                                   -------------------
          otherwise required by law or the certificate of incorporation,
          the holders of one-third of the outstanding shares of each class
          of stock entitled to vote at any meeting of the stockholders,
          present in person or by proxy, shall constitute a quorum.  With
          respect to any matter on which stockholders vote separately as a
          class, the holders of one-third of the outstanding shares of such


                                      2
     

          class shall constitute a quorum for a meeting with respect to
          such matter.  Two or more classes or series of stock shall be
          considered a single class for purposes of determining existence
          of a quorum for any matter to be acted on if the holders thereof
          are entitled or required to vote together as a single class at
          the meeting on such matter.  If a quorum shall fail to attend any
          meeting, the chairman of the meeting may adjourn the meeting from
          time to time, without further notice if the time and place of the
          adjourned meeting are announced at the meeting, until a quorum
          shall be present.  At such adjourned meeting at which a quorum is
          present, any business may be transacted which might have been
          transacted at the original meeting.  If the adjournment is for
          more than 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.

                    SECTION 1.8    RECORD DATE.  In order that the
                                   -----------
          Corporation may determine the stockholders entitled to notice of
          or to vote at any meeting, or at any adjournment of a meeting, of
          stockholders or entitled 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 a record date,
          which record date shall not precede the date upon which the
          resolution fixing the record date is adopted by the board of
          directors.  The record date for determining the stockholders
          entitled to notice of or to vote at any meeting of the
          stockholders or any adjournments thereof shall not be more than
          60 nor less than 10 days before the date of such meeting.  The
          record date for determining the stockholders entitled to consent
          to corporate action in writing without a meeting shall not be
          more than 10 days after the date upon which the resolution fixing
          the record date is adopted by the board of directors.  The record
          date for any other action shall not be more than 60 days prior to
          such action.  If no record date is fixed, (i) the record date for
          determining stockholders entitled to notice of or to vote at any
          meeting shall be at the close of business on the day next
          preceding the day on which notice is given or, if notice is
          waived by all stockholders, at the close of business on the day
          next preceding the day on which the meeting is held; (ii) 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 required, shall be the
          first date on which a signed written consent setting forth the
          action taken or to be taken is delivered to the Corporation by
          delivery to its registered office in the State of Delaware, its
          principal place of business, or an officer of agent of the
          corporation having custody of the book in which proceedings of
          meetings of stockholders are recorded, and, when prior action by
          the board of directors is required, shall be at the close of
          business on the day on which the board of directors adopts the
          resolution taking such prior action; and (iii) 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 to such other purpose.  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.

                    SECTION 1.9    PROCEDURE.  The order of business and
                                   ---------
          all other matters of procedure at every meeting of the
          stockholders may be determined by the presiding officer.

                    SECTION 1.10   ORGANIZATION.  Meetings of stockholders
                                   ------------
          shall be presided over by the chairman of the board, or in his
          absence by the president, or in his absence by a vice president,
          or in the absence of the foregoing persons by a chairman
          designated by the board of directors, or in the absence of such
          designation by a chairman chosen at the meeting.  The secretary
          shall act as secretary of the meeting, but in his absence the
          chairman of the meeting may appoint any person to act as
          secretary of the meeting.

                    SECTION 1.11   VOTING; PROXIES.  Unless otherwise
                                   ---------------
          provided in the certificate of incorporation, each stockholder
          entitled to vote at any meeting of stockholders shall be entitled
          to one vote for each share of stock held by such stockholder
          which has voting power upon the matter in question.  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.  A duly executed proxy shall be irrevocable if it states
          that it is irrevocable and if, and only as long as, it is coupled
          with an interest sufficient in law to support an irrevocable
          power.  A stockholder may revoke any proxy which is not
          irrevocable by attending the meeting and voting in person or by
          filing an instrument in writing revoking the proxy or another
          duly executed proxy bearing a later date with the secretary of
          the Corporation.  Voting at meetings of stockholders need not be
          by written ballot and need not be conducted by inspectors unless
          the holders of a majority of the outstanding shares of any class
          of stock entitled to vote thereon present in person or by proxy
          at such meeting shall so determine.  At all meetings of
          stockholders for the election of directors, such election and all
          other elections and questions shall, unless otherwise provided by
          law or by the certificate of incorporation or these bylaws, be
          decided by the vote of the holders of a majority of the
          outstanding shares of all classes of stock entitled to vote
          thereon present in person or by proxy at the meeting, voting as a
          single class.

                    SECTION 1.12   SHARES HELD BY NOMINEES.  The
                                   -----------------------
          Corporation may establish a procedure by which the beneficial
          owner of shares that are registered in the name of a nominee is
          recognized by the Corporation as a stockholder.  The extent of
          this recognition may be determined in the procedure thus
          established.

                                      ----------

                                  BOARD OF DIRECTORS
                                  ------------------

                    SECTION 2.1    NUMBER, ELECTION, QUALIFICATION AND TERM

          OF OFFICE.  The initial board of directors of the Corporation 
          ---------  
          shall consist of five (5) persons.  The number of directors which 
          shall constitute the whole board of directors shall not be less 
          than three (3) nor more than ten (10).  Within such limits, the 
          number of directors may be fixed from time to time by the board of
          directors.  A director shall be a natural person who is eighteen
          years of age or older.  A director need not be a resident of
          Delaware or a stockholder of the Corporation.  Directors shall be
          elected at each annual meeting of stockholders.  Each director


                                      4
     

          shall hold office until the next annual meeting of stockholders
          following his election and thereafter until his successor shall
          have been elected and qualified.

          may resign at any time upon written notice to the board of
          directors, the chairman of the board or the president of the
          Corporation.  Such resignation shall take effect at the time
          specified therein, and unless otherwise specified therein no
          acceptance of such resignation shall be necessary to make it
          effective.  Any director may be removed with or without cause at
          any time upon the affirmative vote the holders of a majority of
          the outstanding shares of stock of the Corporation then entitled
          to vote at an election of directors.

                    SECTION 2.3    NEWLY CREATED DIRECTORSHIPS AND
                                   -------------------------------
          VACANCIES.  Except as otherwise fixed pursuant to the provisions
          --------- 
          of the certificate of incorporation, newly created directorships
          resulting from any increase in the number of directors and any
          vacancies on the board of directors resulting from death,
          resignation, disqualification, removal or other cause shall be
          filled by the remaining members of the board of directors.  Any
          such vacancies or newly created directorships may also be filled
          upon the affirmative vote of the holders of a majority of the
          outstanding shares of stock of the Corporation entitled to vote
          for the election of directors, given at a special meeting of the
          stockholders called for the purpose.  Each director chosen to
          fill a vacancy shall hold office until the next annual meeting
          and thereafter until his successor shall have been elected and
          qualified.

                    SECTION 2.4    REGULAR MEETINGS.  Regular meetings of
                                   ----------------
          the board of directors shall be held at such times and at such
          places within or without of the State of Delaware as the board of
          directors may from time to time determine.

                    SECTION 2.5    SPECIAL MEETINGS.  Special meetings of
                                   ----------------
          the board of directors may be called at any time, at any place
          and for any purpose by the chairman of the board, any two members
          of the board, or the president.

                    SECTION 2.6    NOTICE OF MEETINGS.  Notice of regular
                                   ------------------
          meetings of the board of directors need not be given.  Notice of
          every special meeting of the board of directors shall be given to
          each director at his usual place of business or at such other
          address as shall have been furnished by him for such purpose. 
          Such notice shall be properly and timely given if it is (a)
          deposited in the United States mail not later than 7 calendar
          days preceding the date of the meeting, or (b) personally
          delivered, telegraphed, sent by facsimile transmission or
          communicated by telephone at least 24 hours before the time of
          the meeting.  Unless required by law, such notice need not
          include a statement of the business to be transacted at, or the
          purpose of, any such meeting.

                    SECTION 2.7    WAIVER.  Attendance of a director at a
                                   ------
          meeting of the board of directors shall constitute a waiver of
          notice of such meeting, except where a director 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.  A written waiver of notice

          signed by a director or directors entitled to such notice,
          whether before, at or after the time for notice or the time of
          the meeting, shall be equivalent to the giving of such notice.

                    SECTION 2.8    QUORUM.  Except as may be otherwise

          necessary and sufficient to constitute a quorum for the
          transaction of business at any meeting of the board of directors. 
          The affirmative vote of a majority of all directors constituting
          the board of directors shall be required for the board of
          directors to act.  In the case of any meeting of the board of

          appointed, shall have such general powers and duties of
          supervision and management as are usually vested in the office of

          stockholders and directors at which he may be present and shall
          have such other duties, powers and authority as may be prescribed
          elsewhere in these bylaws.  The board of directors may delegate
          such other authority and assign such additional duties to the
          chairman of the board, other than those conferred by law
          exclusively upon the president, as it may from time to time
          determine.  The chairman of the board shall hold his position at
          the pleasure of the board of directors and may be removed at any
          time by the board of directors with or without cause.

          participate in a meeting of such board or committee 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.

                                   ------
          affairs of the Corporation shall be managed by or under the
          direction of the board of directors, which shall have and may
          exercise all the powers of the Corporation to do all such lawful
          acts and things as are not by law, by the certificate of
          incorporation or by these bylaws, directed or required to be
          exercised or done by the stockholders.

                    SECTION 2.12   ORGANIZATION.  Meetings of the board of
                                   ------------
          directors shall be presided over by the chairman of the board, or
          in his absence by the president, or in their absence by a
          chairman chosen at the meeting.  The secretary shall act as
          secretary of the meeting, but in his absence the chairman of the
          meeting may appoint any person to act as secretary of the
          meeting.

                    SECTION 2.13   ACTION WITHOUT A 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 any committee thereof may be
          taken without a meeting if written consent thereto is signed by
          all members of the board of directors or of such committee, as
          the case may be, and such written consent is filed with the


                                      6
     

          minutes of proceedings of the board or committee.  Any such
          consent may be in counterparts and shall be effective on the date
          of the last signature thereon unless otherwise provided therein.

                                   ------------
          restricted by the certificate of incorporation or these bylaws,
          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.

          establish committees for the performance of delegated or
          designated functions to the extent permitted by law, each
          committee to consist of one or more 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.  In the
          absence or disqualification of a member of a 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 such absent or
          disqualified member.

          management of the business and affairs of the Corporation, and
          may authorize the seal of the Corporation to be affixed to all

          power or authority in reference to the following matters: (i)
          approving or adopting, or recommending to the stockholders, any
          action or matter expressly required by the Delaware General
          Corporation Law to be submitted to stockholders for approval, or
          (ii) adopting, amending or repealing any bylaw of the
          Corporation..

                    SECTION 3.3    COMMITTEE PROCEDURES.  To the extent the
                                   --------------------

          procedures for the committee, each committee shall be governed by

          need not have annual meetings).

          Corporation shall be entitled to a certificate or certificates
          signed by or in the name of the Corporation by the chairman of
          the board, the president or a vice president and by the
          treasurer, an assistant treasurer, the secretary or an assistant
          secretary, all of whom may be the same person, representing the
          number of shares of stock of the Corporation owned by such

          a facsimile.

                    SECTION 5.2    FACSIMILE SIGNATURES.  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, she or it was such officer,
          transfer agent or registrar at the date of issue.

                    SECTION 5.3    FRACTIONAL SHARES OR SCRIP.  The

          the value of fractions of a share; (b) arrange for disposition of
          fractional shares by the stockholders; or (c) issue scrip in
          registered or bearer form entitling the holder to receive a full
          share upon surrendering enough scrip to equal a full share.  Each
          certificate representing scrip must be conspicuously labeled
          "scrip" and must contain the information required to be included
          in a share certificate by the Delaware General Corporation Law. 
          The holder of a fractional share is entitled to exercise the
          rights of a stockholder, including the right to vote, to receive
          dividends, and to participate in the assets of the Corporation
          upon liquidation.  The holder of scrip is not entitled to any of
          these rights unless the scrip provides for them.  The board of
          directors may authorize the issuance of scrip subject to any
          condition considered desirable, including (a) that the scrip will


                                      10
     

          become void if not exchanged for full shares before a specified
          date; and (b) that the shares for which the scrip is exchangeable
          may be sold and the proceeds paid to the scripholders.

                    SECTION 5.4    REGISTERED STOCKHOLDERS.  The
                                   -----------------------
          Corporation shall be entitled to treat the holder of record of
          any share or shares of stock of the Corporation as the holder in
          fact thereof and, accordingly, 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 has
          actual or other notice thereof, except as provided by law.

                    SECTION 5.5    CANCELLATION OF CERTIFICATES.  All stock

          of an affidavit of that fact by the person claiming the certificate 
          or certificates to be lost, stolen or destroyed.  In its discretion,

          certificate or certificates, the board of directors may require
          that the owner of such lost, stolen or destroyed certificate or

          Corporation and its transfer agent or agents, registrar or
          registrars an indemnity bond in such form and amount as the board
          of directors may direct against any claim that may be made
          against the Corporation and its transfer agent or agents,
          registrar or registrars on account of the alleged loss, theft or
          destruction of any such certificate or the issuance of such new

          with any provisions restricting the transferability of shares
          that may be set forth in the Delaware General Corporation Law,
          the certificate of incorporation, these bylaws, or any written
          agreement in respect thereof, transfers of shares of the
          Corporation shall be made only on the books of the Corporation by
          the registered holder thereof, or by his attorney thereunto
          authorized by power of attorney duly executed and filed with the
          secretary of the Corporation or with a transfer agent or a
          registrar and on surrender of the certificate or certificates for
          such shares properly endorsed and the payment of all taxes
          thereon, if any.  Except as may be otherwise provided by law or
          these bylaws, the person in whose name shares stand on the books
          of the Corporation shall be deemed the owner thereof for all
          purposes as regards the Corporation; provided that whenever any
          transfer of shares shall be made for collateral security, and not
          absolutely, such fact, if known to the secretary of the
          Corporation, shall be so expressed in the entry of transfer.

                    SECTION 5.8    TRANSFER AGENTS AND REGISTRARS.  The
                                   ------------------------------

          registrars of its stock, whose respective duties the board of
          directors may, from time to time, define.  No certificate of
          stock shall be valid until countersigned by a transfer agent, if
          the Corporation shall have a transfer agent, or until registered


                                      11
     

          by the registrar, if the Corporation shall have a registrar.  The

          the Corporation's certificate of incorporation as now or
          hereafter in effect, (i) indemnify any person who was or is
          threatened to be made a party to any threatened, pending or
          completed action, suit or proceeding, whether criminal, civil,
          administrative or investigative (a "Proceeding"), by reason of
          the fact that he or she is or was a director or officer of the
          Corporation, or, by reason of the fact that such officer or
          director is or was serving at the request of the Corporation as a
          director, officer, employee or agent of another corporation,
          partnership, joint venture, trust, association, or other
          enterprise, against all liability and loss suffered and expenses

          or penalties, and amounts paid in settlement reasonably incurred
          by him or her in connection with such Proceeding, including any

          all reasonable expenses incurred by or on behalf of any such
          person in connection with any Proceeding, whether prior to or
          after final disposition of such Proceeding, upon receipt of an

          subrogated to the extent of such payment to all of the rights of
          recovery of the indemnified person therefor, and such person
          shall execute all papers required and shall do everything that
          may be necessary to secure such rights, including the execution
          of such documents necessary to enable the indemnifying party or
          parties to effectively bring suit to enforce such rights.

                    SECTION 6.3    EFFECT OF CERTAIN PROCEEDINGS.  The

          plea of nolo contendere or its equivalent, shall not (except as
          otherwise expressly provided in these bylaws) of itself adversely
          affect the right of any person to indemnification or create a
          presumption that such 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 or, with respect to any
          criminal proceeding, that such person had reasonable cause to
          believe that his conduct was unlawful.

          Proceeding brought by such person, unless the bringing of such

          obligations then existing with respect to any state of facts then
          or theretofore existing or any Proceeding theretofore or
          thereafter brought based in whole or in part upon any such state
          of facts.  The foregoing rights of indemnification shall not be
          deemed exclusive of any other rights to which any director or

          Article VI.

                    SECTION 6.6    INCLUSION OF SUBSIDIARIES AND

          request of such constituent corporation as a director, employee, 
          or agent of another corporation, partnership, joint venture, 
          trust, association, or other entity shall stand in the same 
          position under the provisions of this Article VI with respect 
          to this Corporation as he would if he had served this Corporation

          may, in the discretion of the board of directors, indemnify and
          advance expenses to a person who is not and was not a director or
          officer of the Corporation but who is or was an employee or agent
          of the Corporation.
