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

     2.01  Annual Meeting.  The annual meeting of the shareholders shall be
held in each year on January 15 of each year beginning with the year 1992 at the
hour of 1:30 p.m., or at such other date and hour within thirty days before or
after said date as may be fixed by or under the authority of the Board of
Directors, for the purpose of electing directors and for the transaction of such
other business as may come before the meeting.  If the day fixed for the annual
meeting shall be a legal holiday in the State of Delaware, such meeting shall be
held on the next succeeding business day.  If the election of directors shall
not be held on the day designated herein, or fixed as herein provided, for any
annual meeting of the shareholders, or at any adjournment thereof, the Board of
Directors shall cause the election to be held at a special meeting of the
shareholders as soon thereafter as conveniently may be.

     2.02  Special Meeting.  Special meetings of the shareholders, for any
purpose or purposes, unless otherwise prescribed by statute, may be called by
the President or the Board of Directors or by the person designated in a written
request of holders of not less than one-tenth of all shares of the corporation
entitled to vote at the meeting.

     2.03  Place of Meeting.  The Board of Directors may designate any
place, either within or without the State of Delaware, as the place of meeting
for any annual meeting or for any special meeting called by the Board of
Directors.  A waiver of notice signed by all shareholders entitled to vote at a
meeting may designate any place, either within or without the State of Delaware,
as the place for the holding of such meeting.  If no designation is made, or a
special meeting is otherwise

 
called, the place of meeting shall be the principal business office of the
corporation or such other suitable place in the county of such principal office
as may be designated by the person calling such meeting, but any meeting may be
adjourned to reconvene at any place designated by vote of a majority of the
shares represented at such meeting.

     2.04  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 delivered not less than ten (10) days
before the date of the meeting (unless a longer period is required by law or the
articles of incorporation) nor more than fifty days before the date of the
meeting, either personally or by mail, by or at the direction of the president,
or the secretary, or other officer or persons calling the meeting, to each
shareholder of record entitled to vote at such meeting. if mailed, such notice
shall be deemed to be delivered when deposited in the United States mail,
addressed to the shareholder at his address as it appears on the stock record
books of the corporation, with postage prepaid.

     2.05  Closing of Transfer Books or Fixing of Record Date.  For the
purpose of determining shareholders entitled to notice of or to vote at any
meeting of shareholders or any adjournment thereof, or shareholders entitled to
receive payment of any dividend, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors may provide
that the stock transfer books shall be closed for a stated period but not to
exceed, in any case, fifty days. If the stock transfer books shall be closed for
the purpose of deter-mining shareholders entitled to notice of or to vote at a
meeting of shareholders, such books shall be closed for at least ten days
immediately preceding such meeting.  In lieu of closing the stock transfer
books, the Board of Directors may fix in advance a date as the record date for
any such determination of shareholders, such date in any case to be not more
than fifty days and, in case of a meeting of shareholders, not less than ten
days prior to the date on which the particular action requiring such
determination of shareholders is to be taken.  If the stock transfer books are
not closed and no record date is fixed for the determination of shareholders
entitled to notice of or to vote at a meeting of shareholders, or shareholders
entitled to receive payment of a dividend, the close of business on the date on
which notice of the meeting is mailed or on the date on which the resolution of
the Board of Directors declaring such dividend is adopted, as the case may be,
shall be the record date for such determination of shareholders.  When a
determination of shareholders entitled to vote at any meeting of shareholders
has been made as provided in this section, such determination shall be applied
to any adjournment thereof except where the determination has been made through
the closing of the stock transfer books and the stated period of closing has
expired.

     2.06  Voting Lists.  The officer or agent having charge of the stock
transfer books for shares of the corporation shall, before each meeting of
shareholders, make a complete list of the shareholders entitled to vote at such
meeting, or any adjournment thereof, with the address of and the number of
shares held by each, which list shall be produced and kept open at the time and
place of the meeting and shall be subject to the inspection of any shareholder
during the whole time of the meeting.  The original stock transfer books shall
be prima facie evidence as to who are the shareholders entitled to examine such
list or transfer books or to vote at any meeting of shareholders.  Failure to
comply with the requirements of this section shall not affect the validity of
any action taken at such meeting.

                                      -2-

 
     2.07  Quorum.  Except as otherwise provided in the articles of
incorporation, a majority of the shares entitled to vote, represented in person
or by proxy, shall constitute a quorum at a meeting of shareholders.  If a
quorum is present, the affirmative vote of the majority of the shares
represented at the meeting and entitled to vote on the subject matter shall be
the act of the shareholders unless the vote of a greater number or voting by
classes is required by law or the articles of incorporation. Though less than a
quorum of the outstanding shares are represented at a meeting, a majority of the
shares so represented may adjourn the meeting from time to time without further
notice.  At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified.

     2.08  Conduct of Meetings.  The President, and in his absence, a Vice-
President in the order provided under Section 4.06, and in their absence, any
person chosen by the shareholders present, shall call the meeting of the
shareholders to order and shall act as chairman of the meeting, and the
secretary of the corporation shall act as secretary of all meetings of the
shareholders, but, in the absence of the secretary, the presiding officer may
appoint any other person to act as secretary of the meeting.

     2.09  Proxies.  At all meetings of shareholders, a shareholder
entitled to vote may vote in person or by his proxy appointed in writing by the
shareholder or by his duly authorized attorney in fact.  Such proxy shall be
filed with the Secretary of the corporation before or at the time of the
meeting.  Unless otherwise provided in the proxy, a proxy may be revoked at any
time before it is voted, either by written notice filed with the Secretary or
the acting secretary of the meeting or by oral notice given by the shareholder
to the presiding officer during the meeting.  The presence of a shareholder who
has filed his proxy shall not of itself constitute a revocation.  No proxy shall
be valid after eleven months from the date of its execution, unless otherwise
provided in the proxy.  The Board of Directors shall have the power and
authority to make rules establishing presumptions as to the validity and
sufficiency of proxies.

     2.10  Voting of Shares.  Each outstanding share shall be entitled to
one vote upon each matter submitted to a vote at a meeting of shareholders,
except to the extent that the voting rights of the shares of any class or
classes are enlarged, limited or denied by the articles of incorporation.

     2.11  Voting of Shares by Certain Holders.

          a.  Other Corporations.  Shares standing in the name of another
     corporation may be voted either in person or by proxy, by the president of
     such corporation or any other officer appointed by such president. A proxy
     executed by any principal officer of such other corporation or assistant
     thereto shall be conclusive evidence of the signer's authority to act, in
     the absence of express notice to this corporation, given in writing to the
     Secretary of this corporation, of the designation of some other person by
     the board of directors or the bylaws of such other corporation.

          b.  Legal Representatives and Fiduciaries.  Shares held by an
     administrator, executor, guardian, conservator, trustee in bankruptcy,
     receiver, or assignee for creditors may

                                      -3-

 
     be voted by him, either in person or by proxy, without a transfer of such
     shares into his name, provided that there is filed with the Secretary
     before or at the time or meeting proper evidence of his incumbency and the
     number of shares held. Shares standing in the name of a fiduciary may be
     voted by him, either in person or by proxy. A proxy executed by a fiduciary
     shall be conclusive evidence of the signer's authority to act, in the
     absence of express notice to this corporation, given in writing to the
     Secretary of this corporation, that such manner of voting is expressly
     prohibited or otherwise directed by the document creating the fiduciary
     relationship.

          c.  Pledges.  A shareholder whose shares are pledged shall be entitled
     to vote such shares until the shares have been transferred into the name of
     the pledgee, and thereafter the pledgee shall be entitled to vote the
     shares so transferred.

          d.  Treasury Stock and Subsidiaries.  Neither treasury shares, nor
     shares held by another corporation if a majority of the shares entitled to
     vote for the election of directors of such other corporation is held by
     this corporation, shall be voted at any meeting or counted in determining
     the total number of outstanding shares entitled to vote, but shares of its
     own issue held by this corporation in a fiduciary capacity, or held by such
     other corporation in a fiduciary capacity, may be voted and shall be
     counted in determining the total number of outstanding shares entitled to
     vote.

          e.  Minors.  Shares held by a minor may be voted by such minor in
     person or by proxy and no such vote shall he subject to disaffirmance or
     avoidance, unless prior to such vote the Secretary of the corporation has
     received written notice or has actual knowledge that such shareholder is a
     minor.

          f.  Incompetents and Spendthrifts.  Shares held by an incompetent or
     spendthrift may be voted by such incompetent or spendthrift in person or by
     proxy and no such vote shall be subject to disaffirmance or avoidance,
     unless prior to such vote the Secretary of the corporation has actual
     knowledge that such shareholder has been adjudicated an incompetent or
     spendthrift or actual knowledge of filing of judicial proceedings for
     appointment of a guardian.

          g.  Joint Tenants.  Shares registered in the names of two or more
     individuals who are named in the registration as joint tenants may be voted
     in person or by proxy signed by any one or more of such individuals if
     either (i) no other such individual or his legal representative is present
     and claims the right to participate in the voting of such shares or prior
     to the vote filed with the Secretary of the corporation a contrary written
     voting authorization or direction or written denial of authority of the
     individual present or signing the proxy proposed to be voted, or (ii) all
     such other individuals are deceased and the Secretary of the corporation
     has no actual knowledge that the survivor has been adjudicated not to be
     the successor to the interests of those deceased.

                                      -4-

 
     2.12  Waiver of Notice by Shareholders.  Whenever any notice whatever
is required to be given to any shareholder of the corporation under the articles
of incorporation or by-laws or any provision of law, a waiver thereof in
writing, signed at any time, whether before or after the time of meeting, by the
shareholder entitled to such notice, shall be deemed equivalent to the giving of
such notice; provided that such waiver in respect to any matter of which notice
is required under any provision of the Delaware Business Corporation Act, shall
contain the same information as would have been required to be included in such
notice, except the time and place of meeting.

     2.13  Unanimous Consent Without Meeting.  Any action required or
permitted by the articles of incorporation or by-laws or any provision of law to
be taken at a meeting of the shareholders, may be taken without a meeting if a
consent in writing, setting forth the action so taken, shall be signed by all of
the shareholders entitled to vote with respect to the subject matter thereof.

     3.01  General Powers and Number.  The business and affairs of the
corporation shall be managed by its Board of Directors.  The number of directors
of the corporation shall be at least one (1).  The number of directors
constituting the initial Board of Directors may be increased or decreased from
time to time by action of the shareholders, either at an annual meeting or at a
special meeting of shareholders called for that purpose, but no decrease shall
have the effect of shortening the term of any incumbent director.

     3.02  Tenure and Qualifications.  Each director shall hold office
until the next annual meeting of shareholders and until his successor has been
elected, or until his prior death, resignation, or removal.  A director may be
removed from office by affirmative vote of a majority of the outstanding shares
entitled to vote for the election of such director, taken at a meeting of
shareholders called for that purpose.  A director may resign at any time by
filing his written resignation with the Secretary of the corporation.  Directors

shareholders which precedes it, or such other suitable place as may be announced
at such meeting of shareholders.  The Board of Directors may provide, by
resolution, the time and place, either within or without the State of Delaware,
for the holding of additional regular meetings without other notice than such
resolution.

may be called by or at the request of the President, Secretary, or any two
directors.  The President or Secretary calling any special meeting of the Board

than forty-eight (48) hours previously thereto.  If mailed, such notice shall be
deemed to be delivered when deposited in the United States mail so addressed,
with postage prepaid.  If notice is given by telegram, such notice shall be
deemed to be delivered when the telegram is delivered to the telegraph company,
Whenever any notice whatever is required to be given to any director of the
corporation under the articles of incorporation or bylaws or any provision of
law, a waiver thereof in writing, signed at any time, whether before or after
the time of meeting, by the director entitled to such notice, shall be deemed
equivalent to the giving of such notice.  The attendance of a director at a
meeting shall constitute a waiver of notice of such meeting, except where a
director attends a meeting and objects to the transaction of any business at
such meeting 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 Board of Directors need be specified in the notice or waiver of
notice of such meeting.

     3.06  Quorum.  Except as otherwise provided by law or by the articles
of incorporation or these by-laws, a majority of the number of directors shall
constitute a quorum for the transaction of business at any meeting of the Board
of Directors, but a majority of the directors present (though less than such
quorum) may adjourn the meeting from time to time without further notice.

     3.07  Manner of Acting.  The act of the majority of the directors
present at a meeting at which a quorum is present shall be the act of the Board
of Directors, unless the act of a greater number is required by law or by these
bylaws.

     3.08  Conduct of Meetings.  The President, and in his absence, a Vice-
President in the order provided under Section 4.06, and in their absence, any

Directors, but in the absence of the Secretary, the presiding officer may
appoint any Assistant Secretary or any director or other person present to act
as secretary of the meeting.

     3.09  Vacancies.  Any vacancy occurring in the Board of Directors,
including a vacancy created by an increase in the number of directors, may be
filled until the next succeeding annual election by the affirmative vote of a
majority of the directors then in office, though less than a quorum of the Board
of Directors; provided, that in case of a vacancy created by the removal of a
director by vote of the shareholders, the shareholders shall have the right to
fill such vacancy at the same meeting or any adjournment thereof.

     3.10  Compensation.  The Board of Directors, by affirmative vote of a
majority of the directors then in office, and regardless of any personal
interest of any of its members, may establish

                                      -6-

 
reasonable compensation for all directors for services to the corporation as
directors, officers or otherwise, or may delegate such authority to an
appropriate committee.  The Board of Directors shall also have authority to
provide for or to delegate authority to an appropriate committee to provide for

payments, to directors, officers and employees and to their estates., families,
dependents or beneficiaries on account of prior services rendered by such
directors, officers and employees to the corporation.

present at a meeting of the Board of Directors or a committee thereof of which
he is a member at which action on any corporate matter is taken shall be
presumed to have assented to the action taken unless his dissent shall be
entered in the minutes of the meeting or unless he shall file his written
dissent to such action with the person acting as the secretary of the meeting
before the adjournment thereof or shall forward such dissent by registered mail
to the Secretary of the corporation immediately after the adjournment of the
meeting.  Such right to dissent shall not apply to a director who voted in favor
of such action.

     3.12  Committees.  The Board of Directors by resolution adopted by the
affirmative vote of a majority of the number of directors may designate one or
more committees, each committee to consist of three or more directors elected by
the Board of Directors, which to the extent provided in said resolution as
initially adopted, and as thereafter supplemented or amended by further
resolution adopted by a like vote, shall have and may exercise, when the Board
of Directors is not in session, the powers of the Board of Directors in the
management of the business and affairs of the corporation, except action in
respect to dividends to shareholders, election of the principal officers or the
filling of vacancies in the Board of Directors or committees created pursuant to
this section. The Board of Directors may elect one or more of its members as
alternate members of any such committee who may take the place of any absent
member or members at any meeting of such committee, upon request by the
President or upon request by the chairman of such meeting.  Each such committee
shall make its own rules governing the conduct of its activities and shall make
such reports of its activities to the Board of Directors as the Board of
Directors may request.

     3.13  Unanimous Consent Without Meeting.  Any action required or
permitted by the articles of incorporation or bylaws or any provision of law to
be taken by the Board of Directors at a meeting or by resolution may be taken
without a meeting if a consent in writing, setting forth the action so taken,
shall be signed by all the directors then in office.

removal.

     4.03  Removal.  Any officer or agent may be removed by the Board of
Directors whenever in its judgment the best interests of the corporation will be

necessary or proper to be executed in the course of the corporation's regular
business, or which shall be authorized by resolution of the Board of Directors;

owner.  Where a certificate for shares is presented to the corporation with a
request to register for transfer, the corporation shall not be liable to the
owner or any other person suffering loss as a result of such registration of
transfer if (a) there were on or with the certificate the necessary
endorsements, and (b) the corporation had no duty to inquire into adverse claims

assurance that said endorsements are genuine and effective and in compliance
with such other regulations as may be prescribed under the authority of the

and authority to make all such further rules and regulations not inconsistent

the issue, transfer and registration of certificates representing shares of the

     8.01  By Shareholders.  These by-laws may be altered, amended or
repealed and new by-laws may be adopted by the majority of the shares present or
represented at any annual or special meeting of the shareholders at which a
quorum is in attendance.

repealed and new by-laws may be adopted by the Board of Directors by affirmative
vote of a majority of the number of directors present at any meeting at which a
quorum is in attendance.  No by-laws adopted by the shareholders shall be
amended or repealed by the Board of Directors if the by-law so adopted so

                                      -12-

 
     8.03  Implied Amendments.  Any action taken or authorized by the
shareholders or by the Board of Directors, which would be inconsistent with the
by-laws then in effect but is taken or authorized by affirmative vote of not
less than the number of shares or the number of directors required to amend the
bylaws so that the by-laws would be consistent with such action, shall be given
the same effect as though the by-laws had been temporarily amended or suspended
so far, but only so far, as is necessary to permit the specific action so taken
or authorized.


                                  ARTICLE IX.

                                  FISCAL YEAR
                                  -----------

                                INDEMNIFICATION
                                ---------------

     10.01  Action Against Party Because of Corporate Position.  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 claim, 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, partner,
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 claim, 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
unlawful.  The termination of any claim, action, suit, or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contenders 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.

     10.02  Action by or in the Right of 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 claim, 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, partner, 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

                                      -13-

 
claim, 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 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 for
negligence or misconduct in the performance of his duty to the corporation
unless and only to the extent that the Court of Equity or the court in which
such claim, 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 Equity or such other court shall deem proper.

     10.03  Reimbursement if Successful.  To the extent that a director,
officer, employee, or agent of the corporation has been successful on the merits
or otherwise in defense of any claim, action, suit or proceeding referred to in
Paragraphs 10.01 and 10.02, or in defense of any claims, issue, or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith, notwithstanding
that he has not been successful (on the merits or otherwise) on any other claim,
issue, or matter in any such claim, action, suit or proceeding.

     10.04  Authorization.  Any indemnification under Paragraphs 10.01 and
10.02 (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 Paragraphs 10.01 and
10.02. Such determination shall be made (a) 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 (b) if such a quorum is not obtainable, or, even
if obtainable, a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion, or (c) by the stockholders.

     10.05  Advanced Reimbursement.  Expenses incurred in defending a 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 as
authorized by the Board of Directors in the specific case upon receipt of an
undertaking by or on behalf of the director, officer, employee, or agent to
repay such amount unless it shall ultimately be determined that he is entitled
to be indemnified by the corporation as authorized in this Article.

     10.06  Indemnification Not Exclusive.  The indemnification provided by
this Article shall not be deemed exclusive of any other rights to which these
indemnified may be entitled under any statute, rule of law, provision of
certificate of incorporation, bylaw, 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, and
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.  Where such other provision provides broader
rights of indemnification than these bylaws, said other provision shall control.

     10.07  Insurance.  The corporation shall have power 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

                                      -14-

 
or was serving at the request of the corporation as a director, partner,
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.

     10.08  Invalidly.  The invalidity or unenforceability of any provision
hereof shall not in any way affect the remaining portions hereof, which shall
continue in full force and effect.
