     All documents filed by the Company pursuant to Sections 13(a), 13(c), 14 or
15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
after the date of this Registration Statement and prior to the filing of a

ITEM 4.  DESCRIPTION OF SECURITIES

     Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law ("DGCL") empowers a
Delaware corporation to indemnify any persons who are, or are threatened to be
made, parties to any threatened, pending or completed legal action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of such corporation), by reason of the fact that
such person was an officer, director, employee or agent of such corporation, or
is or was serving at the request of such corporation as a director, officer,
employee or agent of another corporation or enterprise. The indemnity may
include expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided that such person acted in good faith
and in a manner he reasonably believed to be in or not opposed to the
corporation's best interests, and, for criminal proceedings, he had no
reasonable cause to believe his conduct was illegal. A Delaware corporation may




                                       2
<PAGE>   3
indemnify directors, officers, employees or agents in an action by or in the
right of the corporation under the same conditions, except that no
indemnification is permitted without judicial approval if the director, officer,
employee or agent is adjudged to be liable to the corporation in the performance
of his duty. Where a present or former director or officer is successful on the
merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses which such director or
officer actually and reasonably incurred.

     The Company's By-laws provide that it will indemnify its directors and
officers to the fullest extent permitted by Delaware law, except that no
indemnification will be provided to any such person if the indemnification
sought is in connection with a proceeding initiated by such person without the
authorization of the board of directors. The By-laws also provide that the right
of directors and officers to indemnification thereunder shall include the
advancement of expenses incurred in the defense of actions prior to their final
disposition, subject to any DGCL requirements on the provision of repayment
undertakings, and shall be a contract right, non-exclusive of any other right
now possessed or hereafter acquired under any statute, provision of the
Certificate of Incorporation, By-laws, agreements, vote of stockholders or
disinterested directors or otherwise. The Company's amended Certificate of
Incorporation confirms that the Company shall indemnify its directors and
officers in accordance with and pursuant to its By-laws. The Company's By-laws
permit the Company to maintain insurance on behalf of any officer or director,
among others, for any liability arising out of his or her actions in such
capacity, regardless of whether the Company would have the power to indemnify
such person under the DGCL, and the Company's amended Certificate of
Incorporation permits the Company to enter into one or more individual
indemnification agreements providing for additional or different
indemnification.

     In accordance with Section 102(b)(7) of the DGCL, the Company's amended
Certificate of Incorporation provides that directors of the Company shall not be
personally liable for monetary damages for breaches of their fiduciary duty as
directors except for (i) breaches of their duty of loyalty to the Company or its
stockholders, (ii) acts of omissions not in good faith or which involve
intentional misconduct or knowing violations of law, (iii) certain transactions
under Section 174 of the DGCL (unlawful payment of dividends or unlawful stock
purchases or redemptions) or (iv) transactions from which a director derives an
improper personal benefit. The effect of this provision is to eliminate the
personal liability of directors for monetary damages for actions involving a
breach of their fiduciary duty of care, including any actions involving gross
negligence.

     The Company has directors' and officers' liability insurance which
provides, subject to certain policy limits, deductible amounts and exclusions,
coverage for all persons who have been, are or may in the future be, directors
or officers of the Company, against amounts which such persons may pay resulting
from claims against them by reason of their being such directors or officers
during the policy period for certain breaches of duty, omissions or other acts
done or wrongfully attempted or alleged. Such policies provide coverage in
certain situations where the Company cannot directly provide indemnification
under the DGCL.

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 of 1933, as amended (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 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

     (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 registration statement is on Form S-3, Form S-8 or Form F-3, and 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 the Registrant pursuant to Section 13 or 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.



                                       4
<PAGE>   5


(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 (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.

(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 foregoing provisions, 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.

certifies that it has reasonable grounds to believe that it meets all of the

ITEM 4.  DESCRIPTION OF SECURITIES

     Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law ("DGCL") empowers a
Delaware corporation to indemnify any persons who are, or are threatened to be
made, parties to any threatened, pending or completed legal action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of such corporation), by reason of the fact that
such person was an officer, director, employee or agent of such corporation, or
is or was serving at the request of such corporation as a director, officer,
employee or agent of another corporation or enterprise. The indemnity may
include expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided that such person acted in good faith
and in a manner he reasonably believed to be in or not opposed to the
corporation's best interests, and, for criminal proceedings, he had no
reasonable cause to believe his conduct was illegal. A Delaware corporation may

                                       2
3
indemnify directors, officers, employees or agents in an action by or in the
right of the corporation under the same conditions, except that no
indemnification is permitted without judicial approval if the director, officer,
employee or agent is adjudged to be liable to the corporation in the performance
of his duty. Where a present or former director or officer is successful on the
merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses which such director or
officer actually and reasonably incurred.

     The Company's By-laws provide that it will indemnify its directors and
officers to the fullest extent permitted by Delaware law, except that no
indemnification will be provided to any such person if the indemnification
sought is in connection with a proceeding initiated by such person without the
authorization of the board of directors. The By-laws also provide that the right
of directors and officers to indemnification thereunder shall include the
advancement of expenses incurred in the defense of actions prior to their final
disposition, subject to any DGCL requirements on the provision of repayment
undertakings, and shall be a contract right, non-exclusive of any other right
now possessed or hereafter acquired under any statute, provision of the
Certificate of Incorporation, By-laws, agreements, vote of stockholders or
disinterested directors or otherwise. The Company's amended Certificate of
Incorporation confirms that the Company shall indemnify its directors and
officers in accordance with and pursuant to its By-laws. The Company's By-laws
permit the Company to maintain insurance on behalf of any officer or director,
among others, for any liability arising out of his or her actions in such
capacity, regardless of whether the Company would have the power to indemnify
such person under the DGCL, and the Company's amended Certificate of
Incorporation permits the Company to enter into one or more individual
indemnification agreements providing for additional or different
indemnification.

     In accordance with Section 102(b)(7) of the DGCL, the Company's amended
Certificate of Incorporation provides that directors of the Company shall not be
personally liable for monetary damages for breaches of their fiduciary duty as
directors except for (i) breaches of their duty of loyalty to the Company or its
stockholders, (ii) acts of omissions not in good faith or which involve
intentional misconduct or knowing violations of law, (iii) certain transactions
under Section 174 of the DGCL (unlawful payment of dividends or unlawful stock
purchases or redemptions) or (iv) transactions from which a director derives an
improper personal benefit. The effect of this provision is to eliminate the
personal liability of directors for monetary damages for actions involving a
breach of their fiduciary duty of care, including any actions involving gross
negligence.

     The Company has directors' and officers' liability insurance which
provides, subject to certain policy limits, deductible amounts and exclusions,
coverage for all persons who have been, are or may in the future be, directors
or officers of the Company, against amounts which such persons may pay resulting
from claims against them by reason of their being such directors or officers
during the policy period for certain breaches of duty, omissions or other acts
done or wrongfully attempted or alleged. Such policies provide coverage in
certain situations where the Company cannot directly provide indemnification
under the DGCL.

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 of 1933, as amended (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 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

     (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 registration statement is on Form S-3, Form S-8 or Form F-3, and 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 the Registrant pursuant to Section 13 or 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.

                                       4
5

(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 (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.

(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 foregoing provisions, 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.
