ITEM 6:  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law ("DGCL"), inter alia,
empowers a Delaware corporation to 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 (other than an action by or in the right of the
corporation) by reason of the fact that such person 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 or other enterprise, against expenses (including attorneys' fees),
judgments, fines or 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.
Similar indemnity is authorized for such persons against expenses (including
attorneys' fees) actually and reasonably incurred in connection with the
defense or settlement of any such threatened, pending or completed action or
suit by or in the right of the corporation if such person 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.
Similar indemnity is authorized for such persons against expenses (including
attorneys' fees) actually and reasonably incurred in connection with the
defense or settlement of any such threatened, pending or completed action or
suit by or in the right of the corporation if such person acted in good faith
and in a manner he reasonable believed to be or in or not opposed to the best
interests of the corporation, and provided further that (unless a court of
competent jurisdiction otherwise provides) such person shall not have been
adjudged liable to the corporation.  Any such indemnification may be made only
as authorized in each specific case upon a determination by the shareholders or
disinterested directors or by independent legal counsel in a written opinion
that indemnification is proper because the indemnitee has met the applicable
standard of conduct.  The Certificate of Incorporation of the Company provides
that directors and officers shall be indemnified as described above in this
paragraph to the fullest extent permitted by the DGCL; provided, however, that
any such person seeking indemnification in connection with a proceeding (or
part thereof) initiated by such person shall be indemnified only if such
proceeding (or part thereof) was authorized by the board of directors of the
Company.

     Section 145 further authorizes a corporation 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 or
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 otherwise have the power to indemnify him under Section 145.

     The Certificate of Incorporation of the Company provides, that, to the
fullest extent permitted by the DGCL, no director of the Company shall be
personally liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director.  Section 102(b)(7) of the DGCL
currently provides that such provisions do not eliminate the liability of a
director (i) for a breach of the director's duty of loyalty to the Company or
its stockholders, (ii) for acts or omissions not in good faith or which
involved intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL (relating to the declaration of dividends and purchase
or redemption of shares in violation of the DGCL), or (iv) for any transaction
from which the director derived an improper personal benefit.
     

                                     II-2

     The Company maintains policies insuring its and its subsidiaries' officers
and directors against certain liabilities for actions taken in such capacities,
including liabilities under the Securities Act of 1933.

ITEM 9.  UNDERTAKINGS

(a)  Rule 415 Offering.  The Company hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to the Registration Statement:

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

          (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 the
     Registration Statement;

          (iii)  To include any material information with respect to the plan
     of distribution not previously disclosed in the Registration Statement or
     any material change to such information in the Registration Statement;



                                     II-3

<PAGE>   6
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 Company pursuant to Section 13 or Section
15(d) of the Exchange Act that are incorporated by reference in the
Registration Statement.

     (2)  That, for the purpose of determining any liability under the
Securities Act, 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)  Incorporation of Subsequent Exchange Act Documents by Reference.

     The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) 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.

(h)  Form S-8 Registration Statement.

     Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has
been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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 Company 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 Securities Act and will be governed by the final
adjudication of such issue.

ITEM 6:  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law ("DGCL"), inter alia,
empowers a Delaware corporation to 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 (other than an action by or in the right of the
corporation) by reason of the fact that such person 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 or other enterprise, against expenses (including attorneys' fees),
judgments, fines or 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.
Similar indemnity is authorized for such persons against expenses (including
attorneys' fees) actually and reasonably incurred in connection with the
defense or settlement of any such threatened, pending or completed action or
suit by or in the right of the corporation if such person 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.
Similar indemnity is authorized for such persons against expenses (including
attorneys' fees) actually and reasonably incurred in connection with the
defense or settlement of any such threatened, pending or completed action or
suit by or in the right of the corporation if such person acted in good faith
and in a manner he reasonable believed to be or in or not opposed to the best
interests of the corporation, and provided further that (unless a court of
competent jurisdiction otherwise provides) such person shall not have been
adjudged liable to the corporation.  Any such indemnification may be made only
as authorized in each specific case upon a determination by the shareholders or
disinterested directors or by independent legal counsel in a written opinion
that indemnification is proper because the indemnitee has met the applicable
standard of conduct.  The Certificate of Incorporation of the Company provides
that directors and officers shall be indemnified as described above in this
paragraph to the fullest extent permitted by the DGCL; provided, however, that
any such person seeking indemnification in connection with a proceeding (or
part thereof) initiated by such person shall be indemnified only if such
proceeding (or part thereof) was authorized by the board of directors of the
Company.

     Section 145 further authorizes a corporation 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 or
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 otherwise have the power to indemnify him under Section 145.

     The Certificate of Incorporation of the Company provides, that, to the
fullest extent permitted by the DGCL, no director of the Company shall be
personally liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director.  Section 102(b)(7) of the DGCL
currently provides that such provisions do not eliminate the liability of a
director (i) for a breach of the director's duty of loyalty to the Company or
its stockholders, (ii) for acts or omissions not in good faith or which
involved intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL (relating to the declaration of dividends and purchase
or redemption of shares in violation of the DGCL), or (iv) for any transaction
from which the director derived an improper personal benefit.

     The Company maintains policies insuring its and its subsidiaries' officers
and directors against certain liabilities for actions taken in such capacities,
including liabilities under the Securities Act of 1933.

ITEM 9.  UNDERTAKINGS

(a)  Rule 415 Offering.  The Company hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to the Registration Statement:

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

          (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 the
     Registration Statement;

          (iii)  To include any material information with respect to the plan
     of distribution not previously disclosed in the Registration Statement or
     any material change to such information in the Registration Statement;

                                     II-3
6
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 Company pursuant to Section 13 or Section
15(d) of the Exchange Act that are incorporated by reference in the
Registration Statement.

     (2)  That, for the purpose of determining any liability under the
Securities Act, 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)  Incorporation of Subsequent Exchange Act Documents by Reference.

     The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) 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.

(h)  Form S-8 Registration Statement.

     Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has
been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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 Company 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 Securities Act and will be governed by the final
adjudication of such issue.
