Delay"); provided, further, that the Company shall promptly (i) notify the
Investor in writing of the existence of material non-public information giving

                                      SCHEDULE A

          (a)  To the extent permitted by law, the Company will
indemnify and hold harmless the Investor who holds such Registrable Securities,
the directors, if any, of the Investor, the officers, if any, of the Investor,
each person, if any, who controls the Investor within the meaning of the
Securities Act or the Exchange Act (each, an "Indemnified Person" or
"Indemnified Party"), against any losses, claims, damages, liabilities or
reasonable expenses (joint or several) incurred (collectively, "Claims") to
which any of them may become subject under the Securities Act, the Exchange Act
or otherwise, insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations in the Registration
Statement, or any post-effective amendment thereof, or any prospectus included
therein: (i) any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement or any post-effective amendment thereof
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
(ii) any untrue statement or alleged untrue statement of a material fact
contained in the final prospectus (as amended or supplemented, if the Company
files any amendment thereof or supplement thereto with the SEC) or the omission
or alleged omission to state therein any material fact necessary to make the
statements made therein, in light of the circumstances under which the
statements therein were made, not misleading or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation under the Securities Act, the Exchange
Act or any state securities law (the matters in the foregoing clauses (i)
through (iii) being, collectively, "Violations").  Subject to clause (b) of this
Schedule A, the Company shall reimburse the Investor, promptly as such expenses
are incurred and are due and payable, for any reasonable legal fees or other
reasonable expenses incurred by them in connection with investigating or
defending any such Claim.  Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this clause (a) shall not (I)
apply to a Claim arising out of or based upon a Violation which occurs in
reliance upon and in conformity with information furnished in writing to the
Company by or on behalf of any Indemnified Person expressly for use in
connection with the preparation of the Registration Statement or any such
amendment thereof or supplement thereto, (II) be available to the extent such
Claim is based on a failure of the Investor to deliver or cause to be delivered
the prospectus made available by the Company; or (III) apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of the Company, which consent shall not be unreasonably withheld.  The
Investor ill indemnify the Company and its officers, directors and agents and
each person, if any, who controls the Company within the meaning of the
Securities Act or the Exchange Act against any Claims arising out of or based
upon a Violation which occurs in reliance upon and in conformity with
information furnished in writing to the Company, by or on behalf of the
Investor, expressly for use in connection with the preparation of the
Registration Statement, subject to such limitations and conditions as are
applicable to the Indemnification provided by the Company hereunder.

                                                  CONFIDENTIAL TREATMENT REQUEST

Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall
survive the transfer of the Registrable Securities by the Investor pursuant
to Section 8 of this Agreement.

          (b)  Promptly after receipt by an Indemnified Person or
Indemnified Party under this Schedule A of notice of the commencement of any
action (including any governmental action), such Indemnified Person or
Indemnified Party shall, if a Claim in respect thereof is to be made against any
indemnifying party under this Schedule A, deliver to the indemnifying party a
written notice of the commencement thereof and the indemnifying party shall have
the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel mutually satisfactory to the
indemnifying party and the Indemnified Person or the Indemnified Party, as the
case may be.  In case any such action is brought against any Indemnified Person
or Indemnified Party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate in, and, to the
extent that it may wish, jointly with any other indemnifying party similarly
notified, assume the defense thereof, subject to the provisions herein stated
and after notice from the indemnifying party to such Indemnified Person or
Indemnified Party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such Indemnified Person or Indemnified
Party under this Schedule A for any legal or other reasonable out-of-pocket
expenses subsequently incurred by such Indemnified Person or Indemnified Party
in connection with the defense thereof other than reasonable costs of
investigation, unless the indemnifying party shall not pursue the action of its
final conclusion.  The Indemnified Person or Indemnified Party shall have the
right to employ separate counsel in any such action and to participate in the
defense thereof, but the reasonable fees and reasonable out-of-pocket expenses
of such counsel shall not be at the expense of the indemnifying party if the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory to the Indemnified Person or Indemnified Party.  The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any
liability to the Indemnified Person or Indemnified Party under this Schedule A,
except to the extent that the indemnifying party is prejudiced in its ability to
defend such action.  The indemnification required by this Schedule A shall be
made by periodic payments of the amount thereof during the course of the
investigation or defense, as such expense, loss, damage or liability is incurred
and is due and payable.

          (c)  To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise
be liable under this Schedule A to the fullest extent permitted by law;
PROVIDED, HOWEVER, that (a) no contribution shall be made under circumstances
where the maker would not have been liable for indemnification under the
fault standards set forth in this Schedule A; (b) no seller of Registrable
Securities guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from
any seller of Registrable Securities who was not guilty of such fraudulent
