Item 6.  Indemnification of Directors and Officers

          Delaware law provides for the indemnification of
officers and directors in terms sufficiently broad to include
indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under
the Securities Act.  Pursuant to Section 145 of the Delaware
General Corporation Law, a corporation may indemnify an officer
or director if that person acted in good faith and in a manner
reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to criminal
actions or proceedings, had no reason to believe the conduct was
unlawful.

          The Company has adopted provisions in its Bylaws which
limit the liability of its directors and officers to the fullest
extent permitted by Delaware law.  The Company will indemnify
its directors and officers for claims against them arising out
of their duties as directors or officers of the Company.  Such
indemnification includes any attorneys' fees, judgments, fines,
ERISA excise taxes or penalties and amounts paid in settlement
and amounts expended in seeking indemnification granted for such
person under applicable law, the Bylaws or any agreement with
the Company reasonably incurred by a director or officer,
provided such director or officer acted in good faith and in a
manner reasonably believed to be in or not opposed to the best
interests of the Company.  The Company may also advance expenses
(including attorneys' fees) to its directors and officers
relating to such claims.  The Company has purchased and
maintains insurance covering any liabilities asserted against
and incurred by its directors and officers acting in such
capacities, whether or not the Company would have the power or
obligation to indemnify such directors or officers under its
Bylaws.

Item 7.  Exemption from Registration Claimed

          Not Applicable.


Item 8.  Exhibits

          See the attached Exhibit Index at page 8.


Item 9.  Undertakings

     (a)  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:

                                 (i) To include any prospectus
              required by Section 10(a)(3) of 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; and

<PAGE>

                                (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;

               provided, however, that paragraphs (a)(1)(i) and
          (a)(1)(ii) do not apply if 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 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; and

             (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)  The undersigned registrant hereby undertakes
that, for purposes of determining any liability under the
Securities Act, each filing of the registrant's annual report
pursuant to Section 13(a) or 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.

          (c)  Insofar as indemnification for liabilities
arising under the Securities Act may be permitted to directors,
officers and controlling persons of the registrant pursuant to
the provisions described in Item 6 above, or otherwise, the
registrant 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
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 Securities Act and
will be governed by the final adjudication of such issue.

                           SIGNATURES

          Pursuant to the requirements of the Securities Act,
the registrant certifies that it has reasonable grounds to
believe that it meets all of the 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 authorized, in
the City of Los Angeles, State of California, on this 8th day
of June, 2000.

Act"), after the date of this Registration Statement and prior

Item 4.  Description of Securities

          Not Applicable.

Item 5.  Interests of Named Experts and Counsel

          Not Applicable.
Item 6.  Indemnification of Directors and Officers

          Delaware law provides for the indemnification of
officers and directors in terms sufficiently broad to include
indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under
the Securities Act.  Pursuant to Section 145 of the Delaware
General Corporation Law, a corporation may indemnify an officer
or director if that person acted in good faith and in a manner
reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to criminal
actions or proceedings, had no reason to believe the conduct was
unlawful.

          The Company has adopted provisions in its Bylaws which
limit the liability of its directors and officers to the fullest
extent permitted by Delaware law.  The Company will indemnify
its directors and officers for claims against them arising out
of their duties as directors or officers of the Company.  Such
indemnification includes any attorneys' fees, judgments, fines,
ERISA excise taxes or penalties and amounts paid in settlement
and amounts expended in seeking indemnification granted for such
person under applicable law, the Bylaws or any agreement with
the Company reasonably incurred by a director or officer,
provided such director or officer acted in good faith and in a
manner reasonably believed to be in or not opposed to the best
interests of the Company.  The Company may also advance expenses
(including attorneys' fees) to its directors and officers
relating to such claims.  The Company has purchased and
maintains insurance covering any liabilities asserted against
and incurred by its directors and officers acting in such
capacities, whether or not the Company would have the power or
obligation to indemnify such directors or officers under its
Bylaws.

Item 7.  Exemption from Registration Claimed

          Not Applicable.

Item 8.  Exhibits

          See the attached Exhibit Index at page 8.

Item 9.  Undertakings

     (a)  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:

                                 (i) To include any prospectus
              required by Section 10(a)(3) of 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; and
(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;

               provided, however, that paragraphs (a)(1)(i) and
          (a)(1)(ii) do not apply if 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 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; and

             (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)  The undersigned registrant hereby undertakes
that, for purposes of determining any liability under the
Securities Act, each filing of the registrant's annual report
pursuant to Section 13(a) or 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.

          (c)  Insofar as indemnification for liabilities
arising under the Securities Act may be permitted to directors,
officers and controlling persons of the registrant pursuant to
the provisions described in Item 6 above, or otherwise, the
registrant 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
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 Securities Act and
will be governed by the final adjudication of such issue.

S-8 and has duly caused this Registration Statement to be signed
