may be given at any meeting of the stockholders by the stockholders entitled
thereto in person or by proxy appointed by an instrument in writing delivered

of the meeting. 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 all meetings of the stockholders all matters, except
as otherwise provided in the Certificate of Incorporation, these By-Laws or by
law, shall be decided by the vote of a majority of the votes cast by
stockholders present in person or by proxy and entitled to vote thereat, a
quorum being present. Except as otherwise expressly required by law, the vote

unless so directed by the chairman of the meeting. On a vote by ballot each

                               Indemnification

SECTION 1.  Right to Indemnification

     The Corporation shall to the fullest extent permitted by applicable law as
then in effect indemnify any person (the "Indemnitee") who was or is involved in
any manner (including, without limitation, as a party or a witness) or is
threatened to be made so involved in any threatened, pending or completed
investigation, claim, action, suit or proceeding, whether civil, criminal,
administrative or investigative (including without limitation, any action, suit
or proceeding by or in the right of the Corporation to procure a judgment in its
favor) (a "Proceeding") by reason of the fact that he is or was a director,
officer, employee or agent of the Corporation, or is or wall serving at 

 
the request of the Corporation as a director, officer or employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
(including, without limitation, any employee benefit plan) against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
proceeding. Such indemnification shall be a contract right and shall include
the right to receive payment in advance of any expenses incurred by the
Indemnitee in connection with such proceeding, consistent with the provisions
of applicable law as then in effect.

SECTION 2.  Insurance, Contracts and Funding

     The Corporation may purchase and maintain insurance to protect itself and
any Indemnitee against any expenses, judgments, fines and amounts paid in
settlement as specified in Section I of this Article XI or incurred by any
Indemnitee in connection with any proceeding referred to in Section 1 of this
Article XI, to the fullest extent permitted by applicable law as then in effect.
The Corporation may enter into contracts with any director, officer, employee or
agent of the Corporation in furtherance of the provisions of this Article XI and
may create a trust fund, grant a security interest or use other means
(including, without limitation, a letter of credit) to ensure the payment of
such amounts as may be necessary to effect indemnification as provided in this
Article XI.

SECTION 3.  Indemnification; Not Exclusive Right

     The right of indemnification provided in this Article XI shall not be
exclusive of any other rights to which those seeking indemnification may
otherwise be entitled, and the provisions of this Article XI shall inure to the
benefit of the heirs and legal representatives of any person entitled to
indemnity under this Article XI and shall be applicable to Proceedings commenced
or continuing after the adoption of this Article XI, whether arising from acts
or omissions occurring before or after such adoption.

SECTION 4.  Advancement of Expenses; Procedures; Presumptions and
            Effect of Certain Proceedings; Remedies

     In furtherance, but not in limitation of the foregoing provisions, the
following procedures, presumptions and remedies shall apply with respect to
advancement of expenses and the right to indemnification under this Article XI:

     (a)  Advancement of Expenses.  All reasonable expenses incurred by or on
          -----------------------                                            
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the indemnitee 

 
requesting such advance or advances from time to time, whether prior to or
after final disposition of such Proceeding. Such statement or statements shall
reasonably evidence the expenses incurred by the Indemnitee and, if required
by law at the time of such advance, shall include or be accompanied by an
undertaking by or on behalf of the Indemnitee to repay the amounts advanced if
it should ultimately be determined that the Indemnitee is not entitled to be
indemnified against such expenses pursuant to this Article XI.

     (b)  Procedure for Determination of Entitlement to Indemnification.
          ------------------------------------------------------------- 

          (i)     To obtain indemnification under this Article XI, an Indemnitee
          shall submit to the Secretary of the Corporation a written request,
          including such documentation and information as is reasonably
          available to the Indemnitee and reasonably necessary to determine
          whether and to what extent the Indemnitee is entitled to
          indemnification (the "Supporting Documentation").  The determination
          of the Indemnity's entitlement to indemnification shall be made not
          later than 60 days after receipt by the Corporation of the written
          request for indemnification together with the Supporting
          Documentation.  The Secretary of the Corporation shall, promptly upon
          receipt of such a request for indemnification, advise the Board of
          Directors in writing that the Indemnitee has requested
          indemnification.

          (ii)    The Indemnity's entitlement to indemnification under this 
          Article XI shall be determined in one of the following ways: (A) by
          a majority vote of the Disinterested Directors (as hereinafter
          defined), if they constitute a quorum of the Board of Directors; (B)
          by a written opinion of Independent Counsel (as hereinafter defined)
          if (x) a Change of Control (as hereinafter defined) shall have
          occurred and the Indemnitee so requests or (y) a quorum of the Board
          of Directors consisting of Disinterested Directors is not obtainable
          or, even if obtainable, a majority of such Disinterested Directors
          so directs; (C) by the stockholders of the Corporation (but only if
          a majority of the Disinterested Directors, if they constitute a
          quorum of the Board of Directors, presents the issue of entitlement
          to indemnification to the stockholders for their determination); or
          (D) as provided in Section 4(c).

          (iii)    In the event the determination of entitlement to 
          indemnification is to be made by Independent Counsel pursuant to
          Section 4(b)(ii), a majority of the Disinterested Directors shall
          select the Independent Counsel, but only an Independent Counsel to
          which the Indemnitee does not reasonably object; provided, however,
          that if a Change of Control shall have 

 
          occurred, the Indemnitee shall select such Independent Counsel, but
          only an Independent Counsel to which the Board of Directors does not
          reasonably object.

     (c)  Presumptions and Effect of Certain Proceedings.  Except as otherwise
          ----------------------------------------------                      
expressly provided in this Article XI, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article XI upon submission of a request for indemnification together
with the Supporting Documentation in accordance with Section 4(b)(i), and
thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination.  In any event, if the person
or persons empowered under Section 4(b) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor, together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification and the Indemnitee shall be entitled to
such indemnification unless (A)  the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B)  such indemnification is prohibited by law.  The
termination of any Proceeding described in Section 1, or of any claim, issue or
matter therein, by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not, of itself, adversely affect the
---- ----------                                                              
right of the Indemnitee to indemnification or create a presumption that the
Indemnitee did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the Corporation or,
with respect to any criminal Proceeding, that the Indemnitee had reasonable
cause to believe that his conduct was unlawful.

     (d)  Remedies of Indemnitee.
          ---------------------- 

          (i)    In the event that a determination is made pursuant to 
          Section 4(b) that the Indemnitee is not entitled to indemnification
          under this Article XI, (A) the Indemnitee shall be entitled to seek
          an adjudication of his entitlement to such indemnification either,
          at the Indemnity's sole option, in (x) an appropriate court of the
          State of Delaware or any other court of competent jurisdiction or
          (y) an arbitration to be conducted by a single arbitrator pursuant
          to the rules of the American Arbitration Association; (B) any such
          judicial proceeding or arbitration shall be de novo and the
                                                      -------        
          Indemnitee shall not be prejudiced by reason of such adverse
          determination; and (C) if a Change of Control shall have occurred,
          in any such judicial proceeding or arbitration, the Corporation
          shall have the burden of proving that the Indemnitee is not entitled
          to indemnification under this Article XI.

 
          (ii)    If a determination shall have been made or deemed to have been
          made, pursuant to Section 4(b) or 4(c), that the Indemnitee is
          entitled to indemnification, the Corporation shall be obligated to
          pay the amounts constituting such indemnification within five days
          after such determination has been made or deemed to have been made
          and shall be conclusively bound by such determination unless (A) the
          Indemnitee misrepresented or failed to disclose a material fact in
          making the request for indemnification or in the Supporting
          Documentation or (B) such indemnification is prohibited by law. In
          the event that (C) advancement of expenses is not timely made
          pursuant to Section 4(a) or (D) payment of indemnification is not
          made within five days after a determination of entitlement to
          indemnification has been made or deemed to have been made pursuant
          to Section 4(b) or 4(c), the Indemnitee shall be entitled to seek
          judicial enforcement of the Corporation's obligation to pay to the
          Indemnitee such advancement of expenses or indemnification.
          Notwithstanding the foregoing, the Corporation may bring an action,
          in an appropriate court in the State of Delaware or any other court
          of competent jurisdiction, contesting the right of the Indemnitee to
          receive indemnification hereunder due to the occurrence of an event
          described in subclause (A) or (B) of this clause (ii) (a
          "Disqualifying Event"); provided, however, that in any such action
          the Corporation shall have the burden of proving the occurrence of
          such Disqualifying Event.

          (iii)    The Corporation shall be precluded from asserting in any 
          judicial proceeding or arbitration commenced pursuant to this
          Section 4(d) that the procedures and presumptions of this Article XI
          are not valid, binding and enforceable and shall stipulate in any
          such court or before any such arbitrator that the Corporation is
          bound by all the provisions of this Article XI.

          (iv)    In the event that the Indemnitee, pursuant to this Section 
          4(d), seeks a judicial adjudication of or an award in arbitration to
          enforce his rights under, or to recover damages for breach of, this
          Article XI, the Indemnitee shall be entitled to recover from the
          Corporation, and shall be indemnified by the Corporation against,
          any expenses actually and reasonably incurred by him if the
          Indemnitee prevails in such judicial adjudication or arbitration. If
          it shall be determined in such judicial adjudication or arbitration
          that the Indemnitee is entitled to receive part but not all of the
          indemnification or advancement of expenses sought, the expenses
          incurred by the Indemnitee in 

 
          connection with such judicial adjudication or arbitration shall be
          prorated accordingly.

(e)  Definitions.  For purposes of this Section 4:

          the Corporation is then subject to such reporting requirement;
          provided that, without limitation, such a change in control shall "be
          deemed to have occurred if (A)  any "person" (as such term is used in

          owner" (as defined in Rule 13d-3 under the Act), directly or
          indirectly, of securities of the Corporation representing 20% or more
          of the combined voting power of the Corporation's then outstanding

          members of the Board of Directors in office immediately prior to such
          acquisition; (B)  the Corporation is a party to a merger,
          consolidation, sale of assets or other reorganization, or a proxy

          less than a majority of the Board of Directors thereafter; or (C)
          during any period of two consecutive years, individuals who at the
          beginning of such period constituted the Board of Directors (including

          at least two-thirds of the directors then still in office who were
          directors at the beginning of such period) cease for any reason to
          constitute at least a majority of the Board of Directors.

          (ii)    "Disinterested Director" means a director of the Corporation 
          who is not or was not a party to the Proceeding in respect of which

          firm that neither presently is, nor in the past five years has been,
          retained to represent: (i) the Corporation or the Indemnitee in any
          matter material to either such party or (ii) any other party to the
          Proceeding giving rise to a claim for indemnification under this

XI containing any such provision held to be invalid, illegal or unenforceable,
that are not themselves invalid, illegal or unenforceable) shall not in any
way be affected or impaired thereby; and (b) to the fullest extent possible,

of any paragraph of this Article XI containing any such provision held to be
invalid, illegal or unenforceable, that are not themselves invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable.
