ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

DELAWARE GENERAL CORPORATION LAW

     Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a corporation may 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 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, had reasonable cause to believe that his conduct was unlawful.

     Section 145(b) of the DGCL states that a corporation may 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 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 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 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 145(c) of the DGCL provides that to the extent that a director,
officer, employee or agent of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, 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.

                                      3


     Section 145(d) of the DGCL states that any indemnification under
subsections (a) and (b) of Section 145 (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 subsections (a) and (b).  Such determination shall be made (1) 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, even though less than a
quorum or (2) if there are no such directors or if such directors so direct, by
independent legal counsel in a written opinion, or (3) by the stockholders.

     Section 145(e) of the DGCL provides that expenses (including attorneys'
fees) incurred by an officer or director in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the corporation as authorized in Section 145. 
Such expenses (including attorneys' fees) incurred by other employees and agents
may be so paid upon such terms and conditions, if any, as the board of directors
deems appropriate.

     Section 145(f) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, the other subsections of
Section 145 shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
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.

     Section 145(g) of the DGCL provides that a corporation shall have the 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, 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 Section 145.

     Section 145(j) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, Section 145 shall, unless
otherwise provided when authorized or ratified, 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.

RESTATED CERTIFICATE OF INCORPORATION

     The Restated Certificate of Incorporation of the Company provides that a
director of the Company shall not be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability for unlawful payments of dividends or

                                      4


unlawful stock repurchases or redemptions as provided for in Section 174 of 
the DGCL.  If the DCGL is amended to authorize the further elimination or 
limitation of the liability of directors, then the liability of a director of 
the Company, in addition to the limitation on personal liability described 
above, shall be limited to the fullest extent permitted by the amended DCGL.  
Further, any repeal or modification of such provision of the Restated 
Certificate of Incorporation by the stockholders of the Company shall be 
prospective only, and shall not adversely affect any limitation on the 
personal liability of a director of the Company existing at the time of such 
repeal or modification.

BYLAWS

     The Bylaws of the Company provide that the Company will indemnify any
director or officer of the Company to the full extent permitted by applicable
law, and may, if and to the extent authorized by the Board of Directors, so
indemnify such other persons whom it has the power to indemnify against any
liability, reasonable expense or other matter whatsoever.

INSURANCE

     The Company maintains liability insurance for the benefit of its directors
and officers.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers or
controlling persons of the Company pursuant to the foregoing provisions, the
Company has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act, as
amended, and is therefore unenforceable.

ITEM   9. UNDERTAKINGS.

     (a)  RULE 415 OFFERING.  The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement to include
     any material information with respect to the plan of distribution not
     previously disclosed in this Registration Statement or any material change
     to such information in this Registration Statement;

          (2)  That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

     (b)  SUBSEQUENT EXCHANGE ACT DOCUMENTS.  The undersigned Registrant hereby
undertakes that, for purposes of determining any liability under the Securities
Act of 1933, each filing of the 

                                      6


Company's annual report pursuant to Section 13(a) or Section 15(d) of the 
Securities Exchange Act of 1934 (and, where applicable, each filing of an 
employee benefit plan's annual report pursuant to Section 15(d) of the 
Securities Exchange Act of 1934) that is incorporated by reference in this 
Registration Statement shall be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.

     (c)  INDEMNIFICATION.  Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                      7

Securities and Exchange Commission, in respect thereof, in connection with the
registration of the securities that are the subject of this Registration
Statement, which amendments may make such changes to such Registration Statement
as such attorney may deem appropriate.
