     The following documents filed by Registrant with the Securities and

     In addition, all documents subsequently filed by Registrant pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934,
prior to the filing of a post-effective amendment which indicates that all
securities offered have been sold or which deregisters all securities then

Item 6.   Indemnification of Directors and Officers.
- ------    -----------------------------------------

     Under Section 145 of the General Corporation Law of the State of
Delaware, the state in which the Registrant is incorporated, a Delaware
corporation has the power, under specified circumstances, to indemnify its
directors, officers, employees and agents in connection with actions, suits or
proceedings brought against them by a third party, or by or in the right of the
corporation, by reason of the fact that they were or are such directors,
officers, employees or agents.  In general, Section 145 provides that a
corporation has the power to indemnify directors, officers, employees or agents
where the individual acted in good faith and in a manner such individual
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 such individual's conduct was unlawful.  In
circumstances where the individual shall have been adjudged to be liable for
negligence or misconduct in the performance of such individual's duty to the
corporation, indemnification will be allowed only to the extent that the court
considering the action decides, in view of the circumstances, the individual is
entitled to indemnity.

     As permitted by sections 102 and 145 of the Delaware GCL, Registrant's
Certificate of Incorporation, as amended, includes certain provisions whereby
officers and directors of Registrant are to be indemnified against certain
liabilities.  The Certificate of Incorporation also limits to the fullest extent
permitted by Delaware Law a director's liability to Registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
including gross negligence, except liability for (i) breach of the director's
duty of loyalty, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law, (iii) the unlawful
payment of a dividend or unlawful stock purchase or redemption, and (iv) any
transaction from which the director derives an improper personal benefit.
Delaware Law does not permit a corporation to eliminate a director's duty of
care and this provision of Registrant's Certificate of Incorporation has no
effect on the availability of equitable remedies, such as injunction or
rescission, based upon a director's breach of the duty of care.

     Registrant has entered into indemnity agreements with each of its
current directors and officers which provide for indemnification of, and
advancement of expenses to, such persons to the greatest extent permitted by
Delaware Law, including by reason of action or inaction occurring in the past
and circumstances in which indemnification and the advancement of expenses are
discretionary under Delaware Law.

Item 9.   Undertakings.
- ------    ------------

     (a)  The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are
     being made of the securities registered hereby, a post-effective
     amendment to this registration statement:

               (i)  To include any prospectus required by section 10(a)(3)
          of the Securities Act of 1933;

               (ii)  To reflect in the prospectus any facts or events
          arising after the effective date of the registration statement
          (or the most recent post-effective amendment thereof) which, 
          individually or in the aggregate, represent a fundamental change
          in the information set forth in this registration statement;

               (iii)  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;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
     apply if the registration statement is on Form S-3 or Form S-8, and
     the information required to be included in a post-effective amendment
     by those paragraphs is contained in periodic reports filed by the
     Registrant pursuant to section 13 or section 15(d) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the Regis-
     tration 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.

                                       -4-

<PAGE>

     (b)  The undersigned Registrant hereby further undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of the Registrant's annual report pursuant to section 13(a) or section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in the 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)  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 Securities and
Exchange 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 con-
nection 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 indem-
nification by it is against public policy as expressed in the Act and will be
governed by the final adjudication of such issue.

requirements for filing on Form S-8, and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly autho-

- ------    -----------------------------------------------

     The following documents filed by Registrant with the Securities and

     In addition, all documents subsequently filed by Registrant pursuant to

prior to the filing of a post-effective amendment which indicates that all

Item 6.   Indemnification of Directors and Officers.
- ------    -----------------------------------------

     Under Section 145 of the General Corporation Law of the State of
Delaware, the state in which the Registrant is incorporated, a Delaware
corporation has the power, under specified circumstances, to indemnify its
directors, officers, employees and agents in connection with actions, suits or
proceedings brought against them by a third party, or by or in the right of the
corporation, by reason of the fact that they were or are such directors,
officers, employees or agents.  In general, Section 145 provides that a
corporation has the power to indemnify directors, officers, employees or agents
where the individual acted in good faith and in a manner such individual
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 such individual's conduct was unlawful.  In
circumstances where the individual shall have been adjudged to be liable for
negligence or misconduct in the performance of such individual's duty to the
corporation, indemnification will be allowed only to the extent that the court
considering the action decides, in view of the circumstances, the individual is
entitled to indemnity.

     As permitted by sections 102 and 145 of the Delaware GCL, Registrant's
Certificate of Incorporation, as amended, includes certain provisions whereby
officers and directors of Registrant are to be indemnified against certain
liabilities.  The Certificate of Incorporation also limits to the fullest extent
permitted by Delaware Law a director's liability to Registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
including gross negligence, except liability for (i) breach of the director's
duty of loyalty, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law, (iii) the unlawful
payment of a dividend or unlawful stock purchase or redemption, and (iv) any
transaction from which the director derives an improper personal benefit.
Delaware Law does not permit a corporation to eliminate a director's duty of
care and this provision of Registrant's Certificate of Incorporation has no
effect on the availability of equitable remedies, such as injunction or
rescission, based upon a director's breach of the duty of care.

     Registrant has entered into indemnity agreements with each of its
current directors and officers which provide for indemnification of, and
advancement of expenses to, such persons to the greatest extent permitted by
Delaware Law, including by reason of action or inaction occurring in the past
and circumstances in which indemnification and the advancement of expenses are
discretionary under Delaware Law.

Item 9.   Undertakings.
- ------    ------------

     (a)  The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are
     being made of the securities registered hereby, a post-effective
     amendment to this registration statement:

               (i)  To include any prospectus required by section 10(a)(3)
          of the Securities Act of 1933;

               (ii)  To reflect in the prospectus any facts or events
          arising after the effective date of the registration statement
          (or the most recent post-effective amendment thereof) which, 
          individually or in the aggregate, represent a fundamental change
          in the information set forth in this registration statement;

               (iii)  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;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
     apply if the registration statement is on Form S-3 or Form S-8, and
     the information required to be included in a post-effective amendment
     by those paragraphs is contained in periodic reports filed by the
     Registrant pursuant to section 13 or section 15(d) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the Regis-
     tration 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.

                                       -4-
(b)  The undersigned Registrant hereby further undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of the Registrant's annual report pursuant to section 13(a) or section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in the 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)  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 Securities and
Exchange 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 con-
nection 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 indem-
nification by it is against public policy as expressed in the Act and will be
governed by the final adjudication of such issue.

                                       -5-
