                INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

     Section 1. Right to Indemnification

          a. Each person who was or is made a party or is threatened to be made
a party to or is involved in any action, suit or proceeding, whether civil,
criminal, administrative or investigative ("proceeding"), by reason of the fact
that he or she or a person for whom he or she is the legal representative is or
was a director, officer or employee of the corporation or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the corporation to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent such amendment permits the
corporation to provide broader indemnification rights than said law permitted
the corporation to provide prior to such amendment) against all

                                       11



expenses, liability and loss (including attorneys' fees, judgments, fines, ERISA
excise taxes or penalties and amounts paid or to be paid in settlement)
reasonably incurred or suffered by such person in connection therewith;
provided, however, that with respect to any agent or employee, to the extent any
such expenses, liabilities or losses are covered by insurance, other than
insurance maintained by the corporation, the corporation shall be required to
indemnify and hold harmless such agent or employee only to the extent that such
expenses, liabilities or losses are not covered by such insurance. Such right
shall be a contract right and shall include the right to be paid by the
corporation expenses incurred in defending any such proceedings in advance of
its final disposition; provided, however, that the payment of such expenses
incurred by a director or officer of the corporation in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer, including, without
limitation, service to an employee benefit plan) in advance of the final
disposition of such proceeding, shall be made only upon delivery to the
corporation of an undertaking, by or on behalf of such director or officer, to
repay all amounts so advanced if it should be determined ultimately that such
director or officer is not entitled to be indemnified under this section or
otherwise.

          b. Any person who is or was an agent of the corporation, and who would
be entitled to be indemnified by the corporation under the circumstances set
forth in Section 1(a) but for the fact that such person is not or was not a
director, officer or employee of the corporation, may be indemnified by the
corporation (but shall not be entitled to be indemnified by the corporation) in
a specific case to all or part of the extent set forth in Section 1(a), if the
Board of Directors determines that it is in the best interests

                                       12



of the corporation to grant such indemnity. Authorization for such indemnity and
the extent thereof shall be determined by majority vote of a quorum of the Board
of Directors.

     Section 2. Right of Claimant to Bring Suit

     If a claim under Section 1 is not paid in full by the corporation within 90
days after a written claim has been received by the corporation, the claimant
may at any time thereafter bring suit against the corporation to recover the
unpaid amount of the claim, and if successful in whole or in part, the claimant
shall be entitled to be paid also the expenses of prosecuting such claim. It
shall be a defense to any such action (other than an action brought to enforce a
claim for expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking has been tendered to the corporation)
that the claimant has not met the standards of conduct which make it permissible
under the Delaware General Corporation Law for the corporation to indemnify the
claimant for the amount claimed, but the burden of proving such defense shall be
on the corporation. Neither the failure of the corporation (including its Board
of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant had
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that claimant had not met the applicable standard of
conduct.

                                       13



     Section 3. Non-Exclusivity of Rights

other right which such person may have or hereafter acquire under any statute,
provision of the Certificate of Incorporation, bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.

     Section 4. Insurance

     The corporation may maintain insurance, at its expense, to protect itself
and any such director, officer, employee or agent of the corporation or another
corporation, partnership, joint venture, trust or other enterprise against any
such expense, liability or loss, whether or not the corporation would have the
power to indemnify such person against such expense, liability or loss under the
Delaware General Corporation Law.

     Section 5.

     For purposes of this Article, reference to "other enterprise" shall include
entities of any. kind, including associations, rate bureaus and conferences.

written assignment of the certificate or a power of attorney to sell, assign or
transfer the same or the shares represented thereby, signed by the person
appearing by the certificate to be the owner of the shares represented thereby.
Such assignment or power of attorney may be either in blank or to a specified
person.

     Section 4. Change of Address

     Stockholders shall be responsible for notifying in writing the secretary,
or the transfer agent or registrar as the case may be, if appointed by
resolution of the Board, of any changes in their addresses from time to time,
and failure to do so shall relieve the Corporation, its shareholders, directors,
officers and the transfer agent and/or registrar, if any, of liability for
failure to direct notices, dividends, or other documents or property to an
address other than the one appearing in the records of the secretary or, if
appointed, the transfer agent or registrar.
