ITEM 4. DESCRIPTION OF SECURITIES.

      Not Applicable

ITEM 5. INTEREST OF NAMED EXPERTS AND COUNSEL.

      Not Applicable

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

      Section 102 of the Delaware General Corporation Law allows a corporation
to eliminate the personal liability of directors of a corporation to the
corporation or to any of its stockholders for monetary damage for a breach of
his fiduciary duty as a director, except in the case where the director breached
his or her duty of loyalty, failed to act in good faith, engaged in intentional
misconduct or knowingly violated a law, authorized the payment of a dividend or
approved a stock repurchase in violation of Delaware corporate law or obtained
an improper personal benefit. Our Certificate of Incorporation contains a
provision that eliminates directors' personal liability as set forth above.

      Section 145 of the Delaware General Corporation Law empowers a 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,
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 or she 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 and amounts paid in settlement actually and
reasonably incurred by him or her in connection with such action, suit or
proceeding if he or she acted in good faith and in a manner he or she 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 or her conduct was unlawful.

      Section 145 also empowers a 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 or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that such person acted in any of the
capacities set forth above, against expenses (including attorneys' fees)
actually and reasonably incurred by him or her in connection with the defense or
settlement of such action or suit if he or she acted under similar standards,
except that no indemnification may 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 Delaware Court of Chancery
or the court in which such action was brought shall determine that despite the
adjudication of liability such person is fairly and reasonably entitled to
indemnity for such expenses which the Delaware Court of Chancery or such other
court shall deem proper.

      Section 145 further provides that to the extent a director, officer,
employee or agent of a corporation has been successful in the defense of any
action, suit or proceeding referred to above or in the defense of any claim,
issue or matter therein, he or she shall be indemnified against


                                     - 3 -
<PAGE>

expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection therewith; that indemnification provided for by Section 145
shall not be deemed exclusive of any other rights to which the indemnified party
may be entitled; and that the corporation is empowered to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation against any liability asserted against him or her in
any such capacity or arising out of his car or her status as such, whether or
not the corporation would have the power to indemnify him or her against such
liability under Section 145.

      Our Certificate of Incorporation and By-Laws provide that we are required
and permitted to indemnify our officers and directors, employees and agents
under certain circumstances. In addition, if permitted by law, we are required
to advance expenses to our officers and directors as incurred in connection with
proceedings against them in their capacity as a director or officers for which
they may be indemnified 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 such person is not entitled to indemnification. At present, we are not
aware of any pending or threatened litigation or proceeding involving any of our
directors, officers, employees or agents for which indemnification would be
required or permitted.

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

ITEM 9. UNDERTAKINGS.

      A. We hereby undertake:

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

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

            (b) 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. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and

            (c) 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)(a) and (A)(1)(b) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by us 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 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. We hereby undertake that, for purposes of determining any liability
under the Securities Act of 1933, each filing of our 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 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 therein.

      C. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted for our directors, officers and controlling persons
pursuant to the foregoing


                                     - 5 -
<PAGE>

provisions, or otherwise, we have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by us of expenses incurred or paid by a director, officer or
controlling person of ours 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 in this registration statement,
we will, unless in the opinion of our counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by us is against public policy as
expressed in the Securities Act of 1933, and we will be governed by the final
adjudication of such issue.

ITEM 4. DESCRIPTION OF SECURITIES.

      Not Applicable

ITEM 5. INTEREST OF NAMED EXPERTS AND COUNSEL.

      Not Applicable

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

      Section 102 of the Delaware General Corporation Law allows a corporation
to eliminate the personal liability of directors of a corporation to the
corporation or to any of its stockholders for monetary damage for a breach of
his fiduciary duty as a director, except in the case where the director breached
his or her duty of loyalty, failed to act in good faith, engaged in intentional
misconduct or knowingly violated a law, authorized the payment of a dividend or
approved a stock repurchase in violation of Delaware corporate law or obtained
an improper personal benefit. Our Certificate of Incorporation contains a
provision that eliminates directors' personal liability as set forth above.

      Section 145 of the Delaware General Corporation Law empowers a 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,
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 or she 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 and amounts paid in settlement actually and
reasonably incurred by him or her in connection with such action, suit or
proceeding if he or she acted in good faith and in a manner he or she 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 or her conduct was unlawful.

      Section 145 also empowers a 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 or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that such person acted in any of the
capacities set forth above, against expenses (including attorneys' fees)
actually and reasonably incurred by him or her in connection with the defense or
settlement of such action or suit if he or she acted under similar standards,
except that no indemnification may 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 Delaware Court of Chancery
or the court in which such action was brought shall determine that despite the
adjudication of liability such person is fairly and reasonably entitled to
indemnity for such expenses which the Delaware Court of Chancery or such other
court shall deem proper.

      Section 145 further provides that to the extent a director, officer,
employee or agent of a corporation has been successful in the defense of any
action, suit or proceeding referred to above or in the defense of any claim,
issue or matter therein, he or she shall be indemnified against

                                     - 3 -
expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection therewith; that indemnification provided for by Section 145
shall not be deemed exclusive of any other rights to which the indemnified party
may be entitled; and that the corporation is empowered to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation against any liability asserted against him or her in
any such capacity or arising out of his car or her status as such, whether or
not the corporation would have the power to indemnify him or her against such
liability under Section 145.

      Our Certificate of Incorporation and By-Laws provide that we are required
and permitted to indemnify our officers and directors, employees and agents
under certain circumstances. In addition, if permitted by law, we are required
to advance expenses to our officers and directors as incurred in connection with
proceedings against them in their capacity as a director or officers for which
they may be indemnified 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 such person is not entitled to indemnification. At present, we are not
aware of any pending or threatened litigation or proceeding involving any of our
directors, officers, employees or agents for which indemnification would be
required or permitted.

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

ITEM 9. UNDERTAKINGS.

      A. We hereby undertake:

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

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

            (b) 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. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and

            (c) 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)(a) and (A)(1)(b) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by us 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 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. We hereby undertake that, for purposes of determining any liability
under the Securities Act of 1933, each filing of our 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 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 therein.

      C. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted for our directors, officers and controlling persons
pursuant to the foregoing

                                     - 5 -
provisions, or otherwise, we have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by us of expenses incurred or paid by a director, officer or
controlling person of ours 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 in this registration statement,
we will, unless in the opinion of our counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by us is against public policy as
expressed in the Securities Act of 1933, and we will be governed by the final
adjudication of such issue.
