                            Meeting of Stockholders
                            -----------------------

     Section 2.1.  Annual Meeting.  An annual meeting of such holders of capital
stock ("Stock") as are entitled to vote thereat ("Annual Meeting of
Stockholders") shall be held for the election of directors and the transaction
of such other business on a date and time to be determined by the Board of
Directors.  If the Annual Meeting of Stockholders is not held on the date
designated therefor, the Board of Directors shall cause the meeting to be held
as soon thereafter as convenient.

     Section 2.2.  Special Meetings.  In addition to such special meetings as
are provided for by law or by the Certificate of Incorporation, special meetings
of the stockholders of the Corporation may be called at any time by the Board of
Directors, and by the Secretary upon the written request stating the purposes of
any such meeting of the holders of record collectively of at least fifty-one
(51%) percent of the outstanding shares of Stock of the Corporation.  Special
meetings shall be called by means of a notice as provided in Section 2.4 hereof.

     Section 2.3.  Place of Meetings.  All meetings of the stockholders shall be
held at such place within or without the State of Delaware as shall be
designated by the Board of Directors.

     Section 2.4.  Notice of Meetings.  Whenever stockholders are required or

be given which shall state 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.
The notice of each Annual Meeting of Stockholders shall identify each matter
intended to be acted upon at such meeting.  If mailed, the notice shall be
addressed to each stockholder in a postage-prepaid envelope at his address as it
appears on the records of the Corporation unless, prior to the

                                      -2-

 
time of mailing, the Secretary shall have received from any such stockholder a
written request that notices intended for him be mailed to some other address.
In such case, the notice intended for such stockholder shall be mailed to the
address designated in such request. Notice of each meeting of stockholders shall
be delivered personally or mailed not less than ten (10) nor more than sixty
(60) days before the date fixed for the meeting to each stockholder entitled to
vote at such meeting.

     Section 2.5.  Waiver of Notice.  Whenever notice is required to be given, a
written waiver thereof signed by the person entitled to notice whether before or
after the time stated therein for such meeting shall be deemed equivalent to
notice.  Attendance of a person at a meeting of stockholders shall constitute a

meeting of the stockholders need be specified in any written waiver of notice.

     Section 2.6.  Organization of Meetings.  The Chairman of the Board, if any,
shall act as chairman at all meetings of stockholders at which he is present
and, as such chairman, shall call such meetings of stockholders to order and

meeting of stockholders, the duties otherwise provided in this Section to be
performed by him at such meeting shall be performed at such meeting by the
President.  If both the Chairman of the Board and the President shall be absent,
such duties shall be performed by a Vice President designated by the President
to preside at such meeting.  If no such officer is present at such meeting, any
stockholder or the proxy of any stockholder entitled to vote at the meeting may
call the meeting to order and a chairman to preside thereat shall be elected by
a majority of those present and entitled to vote.  The Secretary of the
Corporation shall act as secretary at all meetings of the stockholders but, in
his absence, the chairman of the meeting may appoint any person present to act
as secretary of the meeting.

                                      -3-

 
     Section 2.7.  Stockholders Entitled to Vote.  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 record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which record date shall not be more than sixty nor less than ten days before the
date of such meeting.  If no record date is fixed by the Board of Directors, 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.  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 2.8.  List of Stockholders Entitled to Vote.  The Secretary shall
prepare and make or cause to be prepared and made, at least ten (10) days before
every meeting of stockholders, a complete list of the stockholders entitled to
vote at such meeting, arranged in alphabetical order and showing the address of
each such stockholder as it appears on the records of the Corporation and the
number of shares registered in the name of each such 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 specified in the notice of meeting
within the city where the meeting is to be held or, if not so specified, at the
place where the meeting is to be held, and a duplicate list shall be similarly
open to examination at the principal place of business of the Corporation.  Such
list shall be produced and kept at the time and place of the meeting during the
whole time thereof and may be inspected by any stockholder who is present.

                                      -4-

 
     Section 2.9.  Quorum and Adjournment.  Except as otherwise provided by law
and in the Certificate of Incorporation, the holders of a majority of the shares
of Stock entitled to vote at the meeting shall constitute a quorum at each
meeting of the stockholders.  Where more than one class or series of Stock is
entitled to vote at such a meeting, a majority of the shares of each such class
or series of Stock entitled to vote at such meeting shall constitute a quorum at
such meeting.  In the absence of a quorum, the holders of a majority of all such
shares of Stock present in person or by proxy may adjourn any meeting from time
to time until a quorum shall attend.  At any such adjourned meeting at which a
quorum may be present, any business may be transacted which might have been
transacted at the meeting as originally called.  Notice of an adjourned meeting
need not be given if the time and place thereof are announced at the meeting at
which the adjournment is taken; provided, however, that 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 2.10.  Order of Business.  The order of business at all meetings of
stockholders shall be as determined by the chairman of the meeting.

     Section 2.11.  Vote of Stockholders.  Except as otherwise permitted by law,
by the Certificate of Incorporation or by Section 2.13 hereof, all action by
stockholders shall be taken at a meeting of the stockholders.  Except as
otherwise provided in the Certificate of Incorporation, every stockholder of
record, as determined pursuant to Section 2.7 hereof, who is entitled to vote
shall at every meeting of the stockholders be entitled to one vote for each
share of Stock entitled to participate in such vote held by such stockholder on
the record date.  Every stockholder entitled to vote shall have the right to
vote in person or by proxy.  Except as otherwise provided by law, no vote on any
question upon which a vote of the stockholders may be taken need be by ballot
unless the chairman of the meeting shall determine that it shall be by ballot or
the holders of a majority of the shares of Stock

                                      -5-

 
present in person or by proxy and entitled to participate in such vote shall so
demand. In a vote by ballot each ballot shall state the number of shares voted
and the name of the stockholder or proxy voting. Unless otherwise provided by
law or by the Certificate of Incorporation, each director shall be elected by a
plurality of the votes of the shares of Stock present in person or represented
by proxy at the meeting and entitled to vote on the election of directors and
all other questions shall be decided by a vote of the holders of a majority of
the shares of Stock present in person or represented by proxy at the meeting and
entitled to vote on the question.

     Section 2.12.  Proxies.  Each stockholder entitled to vote at a meeting of
stockholders or to express consent to corporate action in writing without a
meeting may authorize another person or persons to act for him by proxy.  A
proxy acting for any stockholder shall be duly appointed by an instrument in
writing subscribed by such stockholder, 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.

     Section 2.13.  Consent of Stockholders in Lieu of Meeting.  Whenever the
vote of stockholders at a meeting thereof is required or permitted to be taken
for or in connection with any corporate action by any provision of the General
Corporation Law of the State of Delaware, the meeting, prior notice of such
meeting and the vote of the stockholders may be dispensed with and such
corporate action may be taken with the written consent of the stockholders of
Stock having not less than the minimum percentage of the total vote required by
statute for the proposed corporate action, unless the Certificate of
Incorporation or the By-Laws require a greater percentage for such action, in
which case

                                      -6-

 
the consent shall be that of the holders of such greater percentage; provided,
however, that prompt notice is given to all the stockholders who have not
consented of the taking of such corporate action without a meeting by less than
unanimous written consent. Whenever it is intended that action is to be taken by
stockholders without a meeting, a form for expressing consent in writing to such
action shall be sent to all holders of Stock entitled to vote on such action.
Every written consent shall bear the date of signature of each stockholder who
signs the consent and no written consent shall be effective to take the
corporate action referred to therein unless, within sixty days of the earliest
dated written consent received in accordance with these By-Laws, a written
consent or consents signed by a sufficient number of holders to take such action
are delivered to the Corporation in the manner prescribed in these By-Laws.

     Section 2.14.  Record Date for Actions by Written Consent. (a) 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 record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which date 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.  Any
stockholder of record seeking to have the stockholders authorize or take
corporate action by written consent shall, by written notice to the Secretary,
request the Board of Directors to fix a record date.  The Board of Directors
shall promptly, but in all events within ten days after the date on which such a
request is received, adopt a resolution fixing the record date (unless a record
date has previously been fixed by the Board of Directors pursuant to the first
sentence of this Section 2.14(a)).  If no record date has been fixed by the
Board of Directors pursuant to the first sentence of this Section 2.14(a) or
otherwise within ten days of the date on which such a request is received, 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 applicable law, shall be the first date on which a signed written
consent setting forth the action taken or

                                      -7-

 
proposed to be taken is delivered to the Corporation by delivery to its
registered office in Delaware, its principal place of business, or to any
officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery shall be by hand
or by certified or registered mail, return receipt requested. If no record date
has been fixed by the Board of Directors and prior action by the Board of
Directors is required by applicable law, 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.

     (b) In the event of the delivery, in the manner provided by Section
2.14(a), to the Corporation of the requisite written consent or consents to take
corporate action and/or any related revocation or revocations, the Corporation
may engage independent inspectors of elections for the purpose of performing
promptly a ministerial review of the validity of the consents and revocations.
For the purpose of permitting the inspectors to perform such review, no action
by written consent without a meeting shall be effective until such date as the
independent inspectors certify to the Corporation that the consents delivered to
the Corporation in accordance with Section 2.14(a) represent at least the
minimum number of votes that would be necessary to take the corporate action.
Nothing contained in this Section 2.14(b) shall in any way be construed to
suggest or imply that the Board of Directors or any stockholder shall not be
entitled to contest the validity of any consent or revocation thereof, whether
before or after such certification by the independent inspectors, or to take any
other action (including, without limitation, the commencement, prosecution, or
defense of any litigation with respect thereto, and the seeking of injunctive
relief in such litigation).

     Section 2.15.  Attendance at Meetings of Stockholders.   Any stockholder of
the Corporation not entitled to notice of the meeting or to vote at such meeting
shall nevertheless be entitled to attend any meeting of stockholders of the
Corporation.

     Section 2.16.  Notice of Stockholder Nominees.  Only persons who are
nominated in accordance with the procedures set forth in this Section 2.16 shall
be eligible for election as directors of the Corporation.  Nominations of
persons for election to the Board of Directors may be made at a meeting of the
Corporation's Stockholders (a) by or at the direction of the Board of  Directors
or (b) by any Stockholder of the Corporation entitled to vote for the election
of directors at such meeting who complies with the procedures set forth in this
Section 2.16.  All nominations by Stockholders shall be made pursuant to timely
notice in proper written form to the Secretary of the Corporation.  To be
timely, a Stockholder's notice shall be delivered to or mailed and received at
the principal executive offices of the Corporation not less than 50 days nor
more than 75 days prior to the meeting; provided, however, that if less than 65
days notice or prior public disclosure of the date of the meeting is given or
made to the Stockholders, notice by Stockholder must be received at the
principal executive offices of the Corporation not later than the close of
business on the 15/th /day following the day on which such notice of the date of
the meeting was mailed or such public disclosure was made.  Such Stockholder's
notice to the Secretary shall set forth in writing (a) as to each person whom
such Stockholder proposes to nominate for election or re-election as a director,
all information relating to such person that is required to be disclosed in
solicitations of proxies for election of directors, or is otherwise required, in
each case pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended, including, without limitation, such person's written consent to
being named in the proxy statement as a nominee and to serving as a director if
elected; and (b) as to such Stockholder, (i) the name and address, as they
appear on the Corporation's books, of such Stockholder and (ii) the class and
number of shares of the Corporation's capital stock that are beneficially owned
by such Stockholder.  At the request of the Board of Directors, any person
nominated by the Board of Directors for election as a director shall furnish to
the Secretary of the Corporation that information required to be set forth in a
Stockholders notice of nomination which pertains to the nominee.  No person
shall be eligible for election as a director unless nominated in

                                      -9-

 
accordance with the procedures set forth in these By-Laws of the Company. The
chairman of the Stockholders' meeting shall, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
procedures prescribed by these By-Laws, and if he shall so determine, he shall
announce such determination to the meeting and the defective nomination shall be
disregarded.

     Section 2.17.  Stockholder Proposals.  At any special meeting of the
Corporation's Stockholders, only such business brought before the meeting by or
at the direction of the Board of Directors shall be conducted.  At any Annual
Meeting of Stockholders, only such business shall be conducted as shall have
been brought before the meeting (a) by or at the direction of the Board of
Directors or (b) by any Stockholder who complies with the procedures set forth
in this Section 2.17.  For business to be properly brought before an Annual
Meeting of Stockholders by a Stockholder, the Stockholder must give timely
notice thereof in proper written form to the Secretary of the Corporation.  To
be timely, a Stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the Corporation not less than 50 days nor
more than 75 days prior to the meeting; provided, however, that if less than 65
days notice or prior public disclosure of the date of the meeting is given or
made to the Corporation's Stockholders, notice by the Stockholder must be
received at the principal executive offices of the Corporation not later than
the close of business on the 15th day following the day on which such notice of
the date of the Corporation's Annual Meeting of Stockholders was mailed or such
public disclosure was made.  Such Stockholder's notice to the Secretary shall
set forth in writing as to each matter such Stockholder proposes to bring before
the Annual Meeting of Stockholders: (a) a brief description of the business
desired to be brought before the Annual Meeting of Stockholders and the reason
for conducting such business at the Annual Meeting of Stockholders, (b) the name
and address, as they appear on the Corporation's books, of such Stockholder, (c)
the class and number of shares of the Corporation's stock which are beneficially
owned by such Stockholder and (d) any material interest of such Stockholder in
such business.  Notwithstanding anything in these

                                      -10-

 
By-Laws to the contrary, no business shall be conducted at an Annual Meeting of
Stockholders except in accordance with the procedures set forth in this Section
2.17. The chairman of an Annual Meeting of Stockholders shall, if the facts
warrant, determine and declare to the meeting that business was not properly
brought before the meeting in accordance with the provisions of this Section
2.17, and, if he should so determine, he shall so announce such determination to
the meeting and any such business not properly brought before the meeting shall
not be transacted.

specifically enumerated the matters to be acted upon.

preside at all meetings of the Board of Directors at which he is present.  If
the Chairman of the Board shall be absent from any meeting of the Board of

him at such meeting shall be performed by the President.  If both the Chairman
of the Board and the President shall be absent, such duties shall be performed
by a director designated by the President to preside at such meeting.  If no
such officer or director is present at such meeting, one of the directors

Directors shall consist of one or more directors.  By similar vote, the Board of
Directors may designate one or more directors as alternate members of any such

or between the Corporation and any other corporation, partnership, association
or other organization, in which one or more of its directors or officers are
directors or officers or have a financial interest, shall be void or voidable
solely for such reason or solely because the director or officer is present at
or participates in the meeting of the Board of Directors or committee thereof
which authorizes the contract or transaction or solely because his or their
votes are counted for such purpose if:  (a) the material facts as to his
relationship or interest and as to the contract or transaction are disclosed or

named in the certificate evidencing such stock, or by an attorney lawfully
authorized in writing, upon surrender and cancellation of such certificate, with
duly executed assignment and power of transfer endorsed thereon or attached
thereto, and with such proof of the authenticity of the signature thereon as the
Corporation or its agents may reasonably require.

     Section 7.4.  Lost Certificates.  In case any certificate representing
Stock shall be lost, stolen or destroyed, the Board of Directors in its
discretion or any officer or officers thereunto duly authorized by the Board of
Directors may authorize the issuance of a substitute certificate in the place of

case the Corporation may require the owner of the lost, stolen or destroyed
certificate or his legal representative to give the Corporation evidence which
the Corporation determines in its discretion satisfactory of the loss, theft or
destruction of such certificate and of the ownership thereof and may also
require a bond sufficient to indemnify it against any claim that may be made
against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate.

     Section 7.5.  Determination of Stockholders of Record for Certain Purposes.

     Section 8.4.  Indemnification.

     (a) Subject to Subsection (c) of this Section 8.4, 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 proceeding, 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 that 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.

                                      -27-

 
     (b) Subject to Subsection (c) of this Section 8.4, 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 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 him in connection with the defense or settlement of such action or
suit 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; except that no
indemnification shall be made with respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery 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 or such other court shall deem proper.

     (c) Any indemnification under this Section 8.4 (unless ordered by a court)
shall be made by the Corporation only as authorized in the specific case upon a
determination that indemnification of the director, officer, employee or agent
is proper in the circumstances because he has met the applicable standard of
conduct set forth in Subsection (a) or Subsection (b), as the case may be.  Such
determination shall be made (i) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (ii) if such quorum is not obtainable, or, even if obtainable, a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (iii) by the stockholders.  To the extent, however, that a
director, officer, employee or agent of the Corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding described
above, or in defense of

                                      -28-

 
any claim, issue or matter herein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith, without the necessity of authorization in the specific
case.

     (d) Notwithstanding any contrary determination in the specific case under
Subsection (c) of this Section 8.4, and notwithstanding the absence of any
determination thereunder, any director, officer, employee or agent may apply to
any court of competent jurisdiction in the State of Delaware for indemnification
to the extent otherwise permissible under Subsections (a) and (b) of this
Section 8.4.  The basis of such indemnification by a court shall be a
determination by such court that indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standards of conduct set forth in Subsections (a) and (b) of this
Section 8.4, as the case may be.  Notice of any application for indemnification
pursuant to this Section 8.4 shall be given to the Corporation promptly upon the
filing of such application.

     (e) Expenses incurred in defending or investigating a threatened or pending
action, suit or proceeding shall 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 the director, officer, employee or agent to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Corporation as authorized in this Section 8.4.

     (f) The indemnification and advancement of expenses provided by or granted
pursuant to this Section 8.4 shall not be deemed exclusive of any other rights
to which those seeking indemnification or advancement of expenses may be
entitled under any By-law, agreement, contract, vote of stockholders or
disinterested directors or pursuant to the direction (howsoever embodied) of any
court of competent jurisdiction or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office.  It is
the policy of the Corporation that indemnification of the persons specified in

                                      -29-

 
Subsections (a) and (b) of this Section 8.4 shall be made to the fullest extent
permitted by law.  The provisions of this Section 8.4 shall not be deemed to
preclude the indemnification of any person who is not specified in Subsections
(a) and (b) of this Section 8.4 but whom the Corporation has the power or
