                             ARTICLE I

                           STOCKHOLDERS

     SECTION 1. PLACE OF MEETINGS.  All meetings of stockholders shall be 
held at the principal office of the corporation or at such other place as may 
be named in the notice.

     SECTION 2. ANNUAL MEETING.  The annual meeting of stockholders for the 
election of directors and the transaction of such other business as may 
properly come before the meeting shall be held on such date and at such hour 
and place as the directors or an officer designated by the directors may 
determine.  If the annual meeting is not held on the date designated 
therefor, the directors shall cause the meeting to be held as soon thereafter 
as convenient.

     SECTION 3. SPECIAL MEETINGS.  Special meetings of the stockholders may 
be called at any time by the President or a majority of the Board of 
Directors.

     SECTION 4. NOTICE OF MEETINGS.  Except where some other notice is 
required by law, written notice of each meeting of stockholders, stating the 
place, date and hour thereof and the purposes for which the meeting is 
called, shall be given by the Secretary under the direction of the Board of 
Directors or the President, not less than ten nor more than sixty days before 
the date fixed for such meeting, to each stockholder of record entitled to 
vote at such meeting. Notice shall be given personally to each stockholder or 
left at his or her residence or usual place of business or mailed, postage 
prepaid, and addressed to the stockholder at his or her address as it appears 
upon the records of the corporation.  In case of the death, absence, 
incapacity or refusal of the Secretary, such notice may be given by a person 
designated either by the Secretary or by the person or persons calling the 
meeting or by the Board of Directors.  A waiver of such notice in writing, 
signed by the person or persons entitled to said notice, whether before or 
after the time stated therein, shall be deemed equivalent to such notice.  
Attendance of a person at a meeting of stockholders shall constitute a waiver 
of notice of such meeting, except when the 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.  Neither the business to be transacted at, nor the purpose of, any 
regular or special meeting of the stockholders need be specified in any 
written waiver of notice.  Except as required by statute, notice of any 
adjourned meeting of the stockholders shall not be required.



     SECTION 5. RECORD DATE.  The Board of Directors may fix in advance a 
record date for the determination of the stockholders entitled to notice of 
or to vote at any meeting of stockholders, 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.  Such record date shall 
not be more than 60 nor less than 10 days before the date of such meeting, 
nor more than 60 days before any other action to which such record date 
relates.  If no record date is fixed, 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 before the day on which notice 
is given, or, if notice is waived, at the close of business on the day before 
the day on which the meeting is held, and 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 
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 6.  NOMINATION OF DIRECTORS.  Only persons who are nominated in 
accordance with the following procedures shall be eligible for election as 
directors at any annual or special meeting of stockholders. Nominations of 
persons for election as directors may be made only by or at the direction of 
the Board of Directors, or by any stockholder entitled to vote for the 
election of directors at the meeting in compliance with the notice procedures 
set forth in this Section 6.  Such nominations, other than those made by or 
at the direction of the Board of Directors, shall be made pursuant to timely 
notice in writing to the President or the Secretary.  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 45 days before 
the meeting; PROVIDED, HOWEVER, that if less than 60 days' notice or prior 
public disclosure of the date of the meeting is given or made to 
stockholders, notice by the stockholder to be timely must be so received not 
later than the close of business on the 15th 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 shall set forth (a) as to each person 
whom the stockholder proposes to nominate for election or re-election as a 
director, (i) the name, age, business address and residence address of the 
person, (ii) the principal occupation or employment of the person, (iii) the 
class and number of shares of capital stock of the corporation that are 
beneficially owned by the person and (iv) any other information relating to 
the person that is required to be disclosed in solicitations for proxies for 
election of directors pursuant to Regulation 14A under the Securities 
Exchange Act of 1934, as amended, or any successor provision thereto; and (b) 
as to the stockholder giving the notice, (i) the name and record address of 
such stockholder and (ii) the class and number of shares of capital stock of 
the corporation that are beneficially owned by such stockholder.

     The chairman of the meeting shall, if the facts warrant, determine and 
declare to the meeting that a nomination was not made in accordance with the 
foregoing procedure, and if the chairman should so determine, he or she shall 
so declare to the meeting and the defective nomination shall be disregarded.

                                     -2-




     SECTION 7.  ADVANCE NOTICE OF BUSINESS AT ANNUAL MEETINGS. At any annual 
meeting of the stockholders, only such business shall be conducted as shall 
have been properly brought before the meeting.  To be brought properly before 
an annual meeting, business must be either (a) specified in the notice of 
meeting (or any supplement thereto) given by or at the direction of the 
President or the Board of Directors, (b) otherwise properly brought before 
the meeting by or at the direction of the Board of Directors, or (c) properly 
brought before the meeting by a stockholder.  In addition to any other 
applicable requirements, for business to be brought properly before an annual 
meeting by a stockholder, the stockholder must have given timely notice 
thereof in writing to the President or the Secretary.  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 45 days before 
the meeting; PROVIDED, HOWEVER, that if less than 60 days' notice or prior 
public disclosure of the date of the meeting is given or made to 
stockholders, notice by the stockholder to be timely must be so received not 
later than the close of business on the 15th day following the day on which 
such notice of the date of the annual meeting was mailed or such public 
disclosure was made.  A stockholder's notice shall set forth as to each 
matter the stockholder proposes to bring before the annual meeting (i) a 
brief description of the business desired to be brought before the annual 
meeting and the reasons for conducting such business at the annual meeting, 
(ii) the name and record address of the stockholder proposing such business, 
(iii) the class and number of shares of the corporation that are beneficially 
owned by the stockholder and (iv) any material interest of the stockholder in 
such business.

     Notwithstanding anything in these by-laws to the contrary, no business 
shall be conducted at the annual meeting except in accordance with the 
procedures set forth in this Section 7, PROVIDED, HOWEVER, that nothing in 
this Section 7 shall be deemed to preclude discussion by any stockholder of 
any business properly brought before the annual meeting in accordance with 
said procedure.

     The chairman of an annual meeting shall, if the facts warrant, determine 
and declare to the meeting that business was not properly brought before the 
meeting in accordance with the foregoing procedure, and if the chairman 
should so determine, he or she shall so declare to the meeting and any such 
business not properly brought before the meeting shall not be transacted.

     SECTION 8. VOTING LIST.  The officer who has charge of the stock ledger 
of the corporation shall make or have made, at least 10 days before every 
meeting of stockholders, a complete list of the stockholders, arranged in 
alphabetical order and showing the address of each stockholder and the number 
of shares registered in the name of each stockholder.  Such list shall be 
open to the examination of any stockholder for any purpose germane to the 
meeting, during ordinary business hours, for a period of at least 10 days 
before 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 also be produced and kept at the time and place of the meeting during 
the whole time thereof, and may be inspected by any stockholder who is 
present.  The stock ledger shall be the only evidence as to who are the 
stockholders entitled to examine the stock ledger, the list required by this 
section or the books of the corporation, or to vote at any meeting of 
stockholders.

                                    -3-



     SECTION 9. QUORUM OF STOCKHOLDERS.  At any meeting of the stockholders, 
the holders of a majority in interest of all stock issued and outstanding and 
entitled to vote upon a question to be considered at the meeting, present in 
person or represented by proxy, shall constitute a quorum for the 
consideration of such question; but, in the absence of a quorum, a smaller 
group may adjourn any meeting from time to time.  When a quorum is present at 
any meeting, a majority of the votes properly cast shall, except where a 
different vote is required by law, by the Certificate of Incorporation or by 
these by-laws, decide any question brought before such meeting.  Any election 
by stockholders shall be determined by a plurality of the vote cast by the 
stockholders entitled to vote at the election.

     SECTION 10.  PROXIES AND VOTING.  Unless otherwise provided in the 
Certificate of Incorporation, each stockholder shall at every meeting of the 
stockholders be entitled to one vote in person or by proxy for each share of 
the capital stock held of record by such stockholder, but no proxy shall be 
voted or acted upon after three years from its date, unless said proxy 
provides for a longer period.  Persons holding stock in a fiduciary capacity 
shall be entitled to vote the shares so held, and persons whose stock is 
pledged shall be entitled to vote unless in the transfer by the pledgor on 
the books of the corporation the pledgee shall have been expressly empowered 
to vote thereon, in which case only the pledgee or the pledgee's proxy may 
represent said stock and vote thereon.  Shares of the capital stock of the 
corporation belonging to the corporation or to another corporation, a 
majority of whose shares entitled to vote in the election of directors is 
owned by the corporation, shall neither be entitled to vote nor be counted 
for quorum purposes.

     SECTION 11.  CONDUCT OF MEETING.  Meetings of the stockholders shall be 
presided over by one of the following officers in the order specified and if 
present and acting:  the President, a Vice-President (and, in the event there 
be more than one person in any such office, in the order of their seniority), 
or, if none of the foregoing is in office and present and acting, a chairman 
designated by the Board of Directors or, in the absence of such designation, 
a chairman chosen by the stockholders at the meeting.  The Secretary of the 
corporation, if present, or an Assistant Secretary, shall act as secretary of 
every meeting, but if neither the Secretary nor an Assistant Secretary is 
present the chairman of the meeting shall appoint a secretary of the meeting.

     The Board of Directors may adopt such rules, regulations and procedures 
for the conduct of the meeting of stockholders as it shall deem appropriate.  
Except to the extent inconsistent with such rules and regulations as adopted 
by the Board of Directors, the chairman of the meeting shall have the right 
and authority to prescribe such rules, regulations and procedures and to do 
all such acts as, in the judgement of such chairman, are appropriate for the 
proper conduct of the meeting.  Such rules, regulations or procedures, 
whether adopted by the Board of Directors or prescribed by the chairman of 
the meeting, may include, without limitation, (i) the establishment of an 
agenda or order of business for the meeting, (ii) rules and procedures for 
maintaining order at the meeting and the safety of those present, (iii) 
limitations on attendance at or participation in the meeting to stockholders 
of record of the corporation, their duly authorized and constituted proxies 
or such other persons as the chairman of the meeting

                                  -4-



shall determine, (iv) restrictions on entry to the meeting after the time 
fixed for the commencement thereof, and (v) limitations on the time allotted 
to questions or comments by participants.  Unless and to the extent 
determined by the Board of Directors or the chairman of the meeting, meetings 
of stockholders shall not be required to be held in accordance with the rules 
of parliamentary procedure.

                               DIRECTORS

     SECTION 1. GENERAL POWERS.  The business and affairs of the corporation 
shall be managed by or under the direction of a Board of Directors, who may 
exercise all of the powers of the corporation that are not by law required to 
be exercised by the stockholders.  In the event of a vacancy in the Board of 
Directors, the remaining directors, except as otherwise provided by law, may 
exercise the powers of the full Board until the vacancy is filled.

     SECTION 2. NUMBER; ELECTION; TENURE AND QUALIFICATION. Subject to any 
restrictions contained in the Certificate of Incorporation, the number of 
directors that shall constitute the whole Board shall be fixed by resolution 
of the Board of Directors but in no event shall be less than one. The 
directors shall be elected in the manner provided in the Certificate of 
Incorporation, by such stockholders as have the right to vote thereon.  The 
number of directors may be increased or decreased by action of the Board of 
Directors.  Directors need not be stockholders of the corporation.

     SECTION 3. ENLARGEMENT OF THE BOARD.  Subject to any restrictions 
contained in the Certificate of Incorporation, the number of the Board of 
Directors may be increased at any time, such increase to be effective 
immediately unless otherwise specified in the resolution, by vote of a 
majority of the directors then in office.

     SECTION 4. VACANCIES.  Unless and until filled by the stockholders and 
except as otherwise determined by the Board of Directors in establishing a 
series of Preferred Stock as to directors elected by the holders of such 
series, any vacancy in the Board of Directors, however occurring, including a 
vacancy resulting from an enlargement of the Board and an unfilled vacancy 
resulting from the removal of any director, may be filled by vote of a 
majority of the directors then in office although less than a quorum or the 
full Board, or by the sole remaining director.  Each director so chosen to 
fill a vacancy shall serve for a term determined in the manner provided in 
the Certificate of Incorporation.  When one or more directors shall resign 
from the Board, effective at a future date, a majority of the directors then 
in office, including those who have so resigned, shall have the power to fill 
such vacancy or vacancies, the vote thereon to take effect when such 
resignation or resignations shall become effective.  If at any time there are 
no directors in office, then an election of directors may be held in 
accordance with the General Corporation Law of the State of Delaware.

time specified therein, or if no time is specified, at the time of its 
receipt by the President or the Secretary.

     SECTION 6. REMOVAL.  Directors may be removed from office only as 
provided in the Certificate of Incorporation.  The vacancy or vacancies 
created by the removal of a director may be filled by the stockholders at the 
meeting held for the purpose of removal or, if not so filled, by the 
directors in the manner provided in Section 4 of this Article II.

     SECTION 7. COMMITTEES.  The Board of Directors may, by resolution or 
resolutions passed by a majority of the whole Board of Directors, designate 
one or more committees, each committee to consist of one or more directors of 
the corporation.  The Board of Directors may designate one or more directors 
as alternate members of any committee to replace any absent or disqualified 
member at any meeting of the committee.  In the absence or disqualification 
of any member of any such committee, the member or members thereof present at 
any meeting and not disqualified from voting, whether or not such member or 
members 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.  The Board of Directors shall have the power to change 
the members of any such committee at any time, to fill vacancies therein and 
to discharge any such committee, either with or without cause, at any time.

    Any such committee, to the extent permitted by law and to the extent 
provided in a resolution of the Board of Directors or in these by-laws, shall 
have and may exercise all the powers and authority of the Board of Directors 
in the management of the business and affairs of the corporation, and may 
authorize the seal of the corporation to be affixed to all papers that may 
require it.

    A majority of all the members of any such committee may fix its rules of 
procedure, determine its action and fix the time and place, whether within or 
without the State of Delaware, of its meetings and specify what notice 
thereof, if any, shall be given, unless the Board of Directors shall 
otherwise by resolution provide.  Each committee shall keep regular minutes 
of its meetings and make such reports as the Board of Directors may from time 
to time request.

     SECTION 8. MEETINGS OF THE BOARD OF DIRECTORS. Regular meetings of the 
Board of Directors may be held without call or formal notice at such places 
either within or without the State of Delaware and at such times as the Board 
may by vote from time to time determine.  A regular meeting of the Board of 
Directors may be held without call or formal notice immediately after and at 
the same place as the annual meeting of the stockholders, or any special 
meeting of the stockholders at which a Board of Directors is elected.

     Special meetings of the Board of Directors may be held at any place 
either within or without the State of Delaware at any time when called by the 
President, the Secretary or two or more directors.  Reasonable notice of the 
time and place of a special meeting shall be given to each director unless 
such notice is waived by attendance or by written waiver in the manner 

                                     -6-


provided in these by-laws for waiver of notice by stockholders.  Notice may 
be given by, or by a person designated by, the Secretary, the person or 
persons calling the meeting, or the Board of Directors.  No notice of any 
adjourned meeting of the Board of Directors shall be required.  In any case 
it shall be deemed sufficient notice to a director to send notice by mail at 
least seventy-two hours, or by telegram or fax at least forty-eight hours, 
before the meeting, addressed to such director at his or her usual or last 
known business or home address.

    Directors or members of any committee may participate in a meeting of the 
Board of Directors or of such 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 participation by such means shall 
constitute presence in person at such meeting.

     SECTION 9. QUORUM AND VOTING.  A majority of the total number of 
directors shall constitute a quorum, except that when a vacancy or vacancies 
exist in the Board, a majority of the directors then in office (but not less 
than one-third of the total number of the directors) shall constitute a 
quorum. A majority of the directors present, whether or not a quorum is 
present, may adjourn any meeting from time to time.  The vote of a majority 
of the directors present at any meeting at which a quorum is present shall be 
the act of the Board of Directors, except where a different vote is required 
by law, by the Certificate of Incorporation or by these by-laws.

     SECTION 10.     COMPENSATION.  The Board of Directors may fix fees for 
their services and for their membership on committees, and expenses of 
attendance may be allowed for attendance at each meeting. Nothing herein 
contained shall be construed to preclude any director from serving the 
corporation in any other capacity, as an officer, agent or otherwise, and 
receiving compensation therefor.

     SECTION 11.     ACTION WITHOUT MEETING.  Any action required or 
permitted to be taken at any meeting of the Board of Directors or of any 
committee thereof may be taken without a meeting and without notice if a 
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 minutes of proceedings of the Board of Directors or of such committee.

     SECTION 1. CERTIFICATES OF STOCK.  One or more stock certificates, 
signed by the Chairman or Vice-Chairman of the Board of Directors or by the 
President or a Vice-President and by the Treasurer or an Assistant Treasurer 
or the Secretary or an Assistant Secretary, shall be issued to each 
stockholder certifying the number of shares of the corporation's capital 
stock owned by the stockholder.  Any or all signatures on any such 
certificate may be facsimiles. In case any officer, transfer agent or 
registrar who shall have signed or whose facsimile signature shall have 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 or she were such officer, transfer 
agent or registrar at the date of issue.

on transfer pursuant to the Certificate of Incorporation, the by-laws, 
applicable securities laws, or any agreement among any number of stockholders 
or among such holders and the corporation shall have conspicuously noted on 
the face or back of the certificate either the full text of the restriction 
or a statement of the existence of such restriction.

     SECTION 2. TRANSFERS OF SHARES OF STOCK.  Subject to the restrictions, 
if any, stated or noted on the stock certificates, shares of stock may be 
transferred on the books of the corporation by the surrender to the 
corporation or its transfer agent of the certificate representing such shares 
properly endorsed or accompanied by a written assignment or power of attorney 
properly executed, and with such proof of authority or the authenticity of 
signature as the corporation or its transfer agent may reasonably require. 
The corporation shall be entitled to treat the record holder of stock as 
shown on its books as the owner of such stock for all purposes, including the 
payment of dividends and the right to vote with respect to that stock, 
regardless of any transfer, pledge or other disposition of that stock, until 
the shares have been transferred on the books of the corporation in 
accordance with the requirements of these by-laws.

     SECTION 3. LOST CERTIFICATES.  A new stock certificate may be issued in 
the place of any certificate theretofore issued by the corporation and 
alleged to have been lost, stolen, destroyed or mutilated, upon such terms in 
conformity with law as the Board of Directors shall prescribe.  The directors 
may, in their discretion, require the owner of the lost, stolen, destroyed or 
mutilated certificate, or the owner's legal representatives, to give the 
corporation a bond, in such sum as they may direct, to indemnify the 
corporation against any claim that may be made against it on account of the 
alleged loss, theft, destruction or mutilation of any such certificate, or 
the issuance of any such new certificate.

     SECTION 4. FRACTIONAL SHARE INTERESTS.  The corporation may, but shall 
not be required to, issue fractions of a share.  If the corporation does not 
issue fractions of a share, it shall (i) arrange for the disposition of 
fractional interests by those entitled thereto, (ii) pay in cash the fair 
value of fractions of a share as of the time when those entitled to receive 
such fractions are determined, or (iii) issue scrip or warrants in registered 
or bearer form, which shall entitle the holder to receive a certificate for a 
full share upon the surrender of such scrip or warrants aggregating a full 
share.  A certificate for a fractional share shall, but scrip or warrants 
shall not unless otherwise provided therein, entitle the holder to exercise 
voting rights, to receive dividends thereon, and to participate in any of the 
assets of the corporation in the event of liquidation.  The Board of 
Directors may cause scrip or warrants to be issued subject to the conditions 
that they shall become void if not exchanged for certificates representing 
full shares before a specified date, or subject to the conditions that the 
shares for which scrip or warrants are exchangeable may be sold by the 
corporation and the proceeds thereof distributed to the holders of scrip or 
warrants, or subject to any other conditions that the Board of Directors may 
impose.

     SECTION 5. DIVIDENDS.  Subject to the provisions of the Certificate of 
Incorporation, the Board of Directors may, out of funds legally available 
therefor, at any regular or special meeting, declare dividends upon the 
capital stock of the corporation as and when they deem expedient.

                            ARTICLE V

           INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The corporation shall, to the extent legally permissible, indemnify each 
person who may serve or who has served at any time as a director or officer 
of the corporation or of any of its subsidiaries, or who at the request of 
the corporation may serve or at any time has served as a director, officer or 
trustee of, or in a similar capacity with, another organization or an 
employee benefit plan, against all expenses and liabilities (including 
counsel fees, judgments, fines, excise taxes, penalties and amounts payable 
in settlements) reasonably incurred by or imposed upon such person in 
connection with any threatened, pending or completed action, suit or other 
proceeding, whether civil, criminal, administrative or investigative, in 
which he may become involved by reason of his serving or having served in 
such capacity (other than a proceeding voluntarily initiated by such person 
unless he is successful on the merits, the proceeding was authorized by the 
corporation or the proceeding seeks a declaratory judgment regarding his own 
conduct); provided that no indemnification shall be provided for any such 
person with respect to any matter as to which he shall have been finally 
adjudicated in any proceeding not to have acted in good faith in the 
reasonable belief that his action was in the best interests of the 
corporation or, to the extent such matter relates to service with respect to 
any employee benefit plan, in the best interests of the participants or 
beneficiaries of such employee benefit plan; and provided, further, that as 
to any matter disposed of by a compromise payment by such person, pursuant to 
a consent

                                   -11-


decree or otherwise, the payment and indemnification thereof have been 
approved by the corporation, which approval shall not unreasonably be 
withheld, or by a court of competent jurisdiction. Such indemnification shall 
include payment by the corporation of expenses incurred in defending a civil 
or criminal action or proceeding in advance of the final disposition of such 
action or proceeding, upon receipt of an undertaking by the person 
indemnified to repay such payment if he shall be adjudicated to be not 
entitled to indemnification under this article, which undertaking may be 
accepted without regard to the financial ability of such person to make 
repayment.

     A person entitled to indemnification hereunder whose duties include 
service or responsibilities as a fiduciary with respect to a subsidiary or 
other organization shall be deemed to have acted in good faith in the 
reasonable belief that his action was in the best interests of the 
corporation if he acted in good faith in the reasonable belief that his 
action was in the best interests of such subsidiary or organization or of the 
participants or beneficiaries of, or other persons with interests in, such 
subsidiary or organization to whom he had a fiduciary duty.

     Where indemnification hereunder requires authorization or approval by 
the corporation, such authorization or approval shall be conclusively deemed 
to have been obtained, and in any case where a director of the corporation 
approves the payment of indemnification, such director shall be wholly 
protected, if:

          1.  the payment has been approved or ratified (l) by a majority 
vote of a quorum of the directors consisting of persons who are not at that 
time parties to the proceeding, (2) by a majority vote of a committee of two 
or more directors who are not at that time parties to the proceeding and are 
selected for this purpose by the full board (in which selection directors who 
are parties may participate), or (3) by a majority vote of a quorum of the 
outstanding shares of stock of all classes entitled to vote for directors, 
voting as a single class, which quorum shall consist of stockholders who are 
not at that time parties to the proceeding; or

          2.  the action is taken in reliance upon the opinion of independent 
legal counsel (who may be counsel to the corporation) appointed for the 
purpose by vote of the directors or in the manner specified in clauses (l), 
(2) or (3) of subparagraph (i); or

          3.  the payment is approved by a court of competent jurisdiction; or

          4.  the directors have otherwise acted in accordance with the 
standard of conduct set forth in the Delaware General Corporation Law.

     Any indemnification or advance of expenses under this article shall be 
paid promptly, and in any event within 30 days, after the receipt by the 
corporation of a written request therefor from the person to be indemnified, 
unless with respect to a claim for indemnification the corporation shall have 
determined that the person is not entitled to indemnification.  If 


                                   -12-


the corporation denies the request or if payment is not made within such 30 
day period, the person seeking to be indemnified may at any time thereafter 
seek to enforce his rights hereunder in a court of competent jurisdiction 
and, if successful in whole or in part, he shall be entitled also to 
indemnification for the expenses of prosecuting such action.  Unless 
otherwise provided by law, the burden of proving that the person is not 
entitled to indemnification shall be on the corporation.

     The right of indemnification under this article shall be a contract 
right inuring to the benefit of the directors, officers and other persons 
entitled to be indemnified hereunder and no amendment or repeal of this 
article shall adversely affect any right of such director, officer or other 
person existing at the time of such amendment or repeal.

     The indemnification provided hereunder shall inure to the benefit of the 
heirs, executors and administrators of a director, officer or other person 
entitled to indemnification hereunder.  The indemnification provided 
hereunder may, to the extent authorized by the corporation, apply to the 
directors, officers and other persons associated with constituent 
corporations that have been merged into or consolidated with the corporation 
who would have been entitled to indemnification hereunder had they served in 
such capacity with or at the request of the corporation.

     The right of indemnification under this article shall be in addition to 
and not exclusive of all other rights to which such director or officer or 
other persons may be entitled.  Nothing contained in this article shall 
affect any rights to indemnification to which corporation employees or agents 
other than directors and officers and other persons entitled to 
indemnification hereunder may be entitled by contract or otherwise under law.

     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 or was serving at the request of the corporation as a 
director, officer, trustee, employee or agent of another corporation, 
partnership, joint venture, trust, other enterprise or employee benefit plan 
against any liability asserted against such person and incurred by such 
person in any such capacity or arising out of such person's status as such, 
whether or not the corporation would have the power to indemnify such person 
against such liability under the provisions of the General Corporation Law of 
the State of Delaware.

debentures, checks, drafts and other orders for the payment of money. In 
addition, the Board of Directors, the President, the Treasurer and the 
Secretary may expressly delegate such powers to any other officer or agent of 
the corporation.

     SECTION 5. VOTING OF SECURITIES.  The President, the Treasurer and the

persons to act as, proxy or attorney-in-fact for this corporation (with or 
without power of substitution) at any meeting of stockholders or owners of 
other interests of any other corporation or organization the securities of 
which may be held by this corporation.  In addition, the Board of Directors, 
the President and the Treasurer may expressly delegate such powers to any

     SECTION 6. EVIDENCE OF AUTHORITY.  A certificate by the Secretary, an 
Assistant Secretary or a temporary secretary as to any action taken by the 
stockholders, directors, a committee or any officer or representative of the 
corporation shall, as to all persons who rely on the certificate in good 
faith, be conclusive evidence of that action.

     SECTION 7. TRANSACTIONS WITH INTERESTED PARTIES.  No contract or 
transaction between the corporation and one or more of the directors or 
officers, or between the corporation and any other corporation, partnership, 
association or other organization in which one or more of the directors or 
officers are directors or officers or have a financial interest, shall be 
void or voidable solely for that reason or solely because the director or 
officer is present at or participates in the meeting of the Board of 
Directors or a committee of the Board of Directors that authorizes the 
contract or transaction or solely because the vote of any such director is 
counted for such purpose, if:

                                  -14-



     (1)  The material facts as to the relationship or interest and as to the 
contract or transaction are disclosed or are known to the Board of Directors 
or such committee, and the Board or committee in good faith authorizes the 
contract or transaction by the affirmative votes of a majority of the 
disinterested directors, even though the disinterested directors be less than 
a quorum; or

     (2)  The material facts as to the relationship or interest and as to the 
contract or transaction are disclosed or are known to the stockholders 
entitled to vote thereon, and the contract or transaction is specifically 
approved in good faith by vote of the stockholders; or

     (3)  The contract or transaction is fair to the corporation as of the 
time it is authorized, approved or ratified by the Board of Directors, a 
committee of the Board of Directors or the stockholders.

     Common or interested directors may be counted in determining the 
presence of a quorum at a meeting of the Board of Directors or of a committee 
that authorizes the contract or transaction.

     SECTION 8. BOOKS AND RECORDS.  The books and records of the corporation 
shall be kept at such places within or without the State of Delaware as the
