at, or to act as secretary of, such meeting may adjourn such meeting from time
to time.  At any such adjourned meeting at which a quorum is present any
business may be transacted which might have been transacted at the meeting as

     (a)  Each stockholder shall, at each meeting of the stockholders, be

stock of the Corporation having voting rights on the matter in question and
which shall have been held by him and registered in his name on the books of the
Corporation:

           (i)  on the date fixed pursuant to Section 6.05 of these Bylaws as 
      the record date for the determination of stockholders entitled to notice
      of and to vote at such meeting, or

      of the meeting shall be given or (b) if notice of the meeting shall be

     (b)  Shares of its own stock belonging to the Corporation or to another
corporation, if a majority of the shares entitled to vote in the election of

Corporation, shall neither be entitled to vote nor be counted for quorum

shall be entitled to vote such stock.  Persons whose stock is pledged shall be
entitled to vote, unless in the transfer by the pledgor on the books of the
Corporation he shall have expressly empowered the 


                                      3

<PAGE>

pledgee to vote thereon, in which case only the pledgee, or his proxy, may 
represent such stock and vote thereon.  Stock having voting power standing of 
record in the names of two or more persons, whether fiduciaries, members of a 
partnership, joint tenants in common, tenants by entirety or otherwise, or 
with respect to which two or more persons have the same fiduciary 
relationship, shall be voted in accordance with the provisions of the General 
Corporation Law of the State of Delaware.

     (c)  Any such voting rights may be exercised by the stockholder entitled
thereto in person or by his proxy appointed by an instrument in writing,
subscribed by such stockholder or by his attorney thereunto authorized and
delivered to the secretary of the meeting; provided, however, that no proxy
shall be voted or acted upon after three years from its date unless said proxy
shall provide for a longer period.  The attendance at any meeting of a
stockholder who may theretofore have given a proxy shall not have the effect of
revoking the same unless he shall in writing so notify the secretary of the
meeting prior to the voting of the proxy.  At any meeting of the stockholders
all matters, except as otherwise provided in the Certificate of Incorporation,
in these Bylaws or by law, shall be decided by the vote of a majority in voting
interest of the stockholders present in person or by proxy and entitled to vote
thereat and thereon, a quorum being present.  The vote at any meeting of the
stockholders on any question need not be by ballot, unless so directed by the
chairman of the meeting.  On a vote by ballot each ballot shall be signed by the
stockholder voting, or by his proxy, if there be such proxy, and it shall state
the number of shares voted.

     SECTION 2.07   LIST OF STOCKHOLDERS.  The Secretary of the Corporation
shall prepare and make, at least 10 days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address 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 prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall 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.

     SECTION 2.08   JUDGES.  If at any meeting of the stockholders a vote by
written ballot shall be taken on any question, the chairman of such meeting may
appoint a judge or judges to act with respect to such vote.  Each judge so
appointed shall first subscribe an oath faithfully to execute the duties of a
judge at such meeting with strict impartiality and according to the best of his
ability.  Such judges shall decide upon the qualification of the voters and
shall report the number of shares represented at the meeting and entitled to
vote on such question, shall conduct and accept the votes, and, when the voting
is completed, shall ascertain and report the number of shares voted respectively
for and against the question.  Reports of judges shall be in writing and
subscribed and delivered by them to the Secretary of the Corporation.  The
judges need not be stockholders of the Corporation, and any officer of the
Corporation may be a judge on any question other than a vote for or against a
proposal in which he shall have a material interest.

Corporation shall be entitled to have a certificate or certificates, to be in
such form as the Board shall prescribe, certifying the number and class of

transfer agent or registrar who has signed, or whose facsimile signature has
been placed upon, any such certificate, shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, such certificate
may nevertheless be issued by the Corporation with the same effect as though the
person who signed such certificate, or whose facsimile signature shall have been

corporations owning the stock represented by such certificates, the number and
class of shares represented by such certificates, respectively, and the
respective dates thereof, and in case of cancellation, the respective dates of
cancellation.  Every certificate surrendered to the Corporation for exchange or

duly executed and filed with the Secretary, or with a transfer clerk or a
transfer agent appointed as provided in Section 6.03, and upon surrender of the
certificate or certificates for such shares properly endorsed and the payment of
all taxes thereon.  The person in whose name shares of stock stand on the books
of the Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation.  Whenever any transfer of shares shall be made for collateral
security, and not absolutely, such fact shall be so expressed in the entry of
transfer if, when the certificate or certificates shall be presented to the
Corporation for transfer, both the transferor and the transferee request the
Corporation to do so.

case of loss, theft, destruction or mutilation of any certificate of stock,
another may be issued in its place upon proof of such loss, theft, destruction
or mutilation and upon the giving of a bond of indemnity to the Corporation in
such form and in such sum as the Board may direct; provided, however, that a new
certificate may be issued without requiring any bond when, in the judgment of
the Board, it is proper so to do.

     SECTION 6.05   FIXING DATE FOR DETERMINATION OF STOCKHOLDERS OF RECORD.  In
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any other change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board may fix, in advance, a record date, which shall not be more than 60
nor less than 10 days before the date of such meeting, nor more than 60 days
prior to any other action.  If in any case involving the determination of
stockholders for any purpose other than notice of or voting at a meeting of
stockholders or expressing consent to corporate action without a meeting the
Board shall not fix such a record date, the record date for determining
stockholders for such purpose shall be the close of business on the day on which
the Board shall adopt the resolution relating thereto.  A determination of
stockholders entitled to notice of or to vote at a meeting of stockholders shall
apply to any adjournment of such meeting; provided, however, that the Board may
fix a new record date for the adjourned meeting.

                                  ARTICLE VII

                                INDEMNIFICATION

     SECTION 7.01   ACTION, ETC., OTHER THAN BY OR IN THE RIGHT OF THE
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
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 


                                     11

<PAGE>

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 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, that he had 
reasonable cause to believe that his conduct was unlawful.

     SECTION 7.02   ACTIONS, ETC., BY OR IN THE RIGHT OF THE 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 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 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 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.

     SECTION 7.03   DETERMINATION OF RIGHT OF INDEMNIFICATION.  Any
indemnification under Section 7.01 or 7.02 (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 Section 7.01 and 7.02. Such determination shall be made 
(i) by the Board by a majority vote of a quorum consisting of directors who 
were not parties to such action, suit or proceeding, or (ii) 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 (iii) by 
the stockholders.

     SECTION 7.04   INDEMNIFICATION AGAINST EXPENSES OF SUCCESSFUL PARTY. 
Notwithstanding the other provisions of this Article, 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 action, suit or proceeding referred to
in Section 7.01 or 7.02, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

     SECTION 7.05   PREPAID EXPENSES.  Expenses incurred by an officer or
director 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 in the specific case upon receipt of an
undertaking by or on behalf of the director or officer to repay 


                                      12

<PAGE>

such amount unless it shall ultimately be determined that he is entitled to 
be indemnified by the Corporation as authorized in this Article.  Such 
expenses incurred by other employees and agents may be so paid upon such 
terms and conditions, if any, as the Board deems appropriate.

     SECTION 7.06   OTHER RIGHTS AND REMEDIES.  The indemnification provided by
this Article shall not be deemed exclusive of any other rights to which those
seeking indemnification may be entitled under any Bylaws, 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.

     SECTION 7.07   INSURANCE.  Upon resolution passed by the Board, the
Corporation may 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, 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.

     SECTION 7.08   CONSTITUENT CORPORATIONS.  For the purposes of this Article,
references to "the Corporation" include all constituent corporations absorbed in
a consolidation or merger as well as the resulting or surviving corporation, so
that any person who is or was a director, officer, employee or agent of such a
constituent corporation or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise shall stand in the same
position under the provisions of this Article with respect to the resulting or
surviving corporation as he would if he had served the resulting or surviving
corporation in the same capacity.

     SECTION 7.09   OTHER ENTERPRISES, FINES AND SERVING AT CORPORATION'S
REQUEST.  For purposes of this Article, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to any employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a director, officer, employee or agent of the Corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the Corporation" as referred to in this
Article.

                                 MISCELLANEOUS

     SECTION 8.01   SEAL.  The Board shall provide a corporate seal, which shall
be in the form of a circle and shall bear the name of the Corporation and words
and figures showing that the Corporation was incorporated in the State of
Delaware and the year of incorporation.

     SECTION 8.02   WAIVER OF NOTICES.  Whenever notice is required to be given
by these Bylaws or the Certificate of Incorporation or by law, the person
entitled to said notice may waive such notice in writing, either before or after
the time stated therein, and such waiver shall be deemed equivalent to notice.

     SECTION 8.03   AMENDMENTS.  These Bylaws, or any of them, may be altered,
amended or repealed, and new Bylaws may be made, (i) by the Board, by vote of a
majority of the number of directors then in office as directors, acting at any
meeting of the Board, or (ii) by the stockholders, at any annual meeting of
stockholders, without previous notice, or at any special meeting of
stockholders, provided that notice of such proposed amendment, modification,
repeal or adoption is given in the notice of special meeting.  Any Bylaws made
or altered by the stockholders may be altered or repealed by either the Board or
the stockholders.
