             and


      (c)    The Registrant's Registration Statement No. 001-12652 on Form 8-A
             filed with the SEC on December 6, 1993 in which the terms, rights
             and provisions applicable to the Registrant's Common Stock are
             described and the Registrant's Registration Statement No. 000-23034
             on Form 8-A filed with the SEC on March 20, 1998, as amended, in
             which the terms, rights and provisions applicable to the
             Registrant's Preferred Stock Purchase Rights are described.


      All reports and definitive proxy or information statements filed pursuant
to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 (the
"1934 Act") after the date of this Registration Statement and prior to the
filing of a post-effective amendment which indicates that all securities offered
hereby have been sold or which deregisters all securities then remaining unsold
shall be deemed to be incorporated by reference into this Registration Statement
and to be a part hereof from the date of filing of such documents. Any statement
contained in a document incorporated or deemed to be incorporated by reference
herein shall be deemed to be modified or superseded for purposes of this
Registration Statement to the extent that a statement contained herein or in any
subsequently filed document which also is deemed to be incorporated by reference
herein modifies or supersedes such statement. Any such statement so modified or
superseded shall not be deemed, except as so modified or superseded, to
constitute a part of this Registration Statement.

ITEM 4.  DESCRIPTION OF SECURITIES

      Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

      Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

      The Registrant's Bylaws (the "Bylaws") provide that the Registrant shall,
to the fullest extent authorized by Delaware law, indemnify any director who is
made, or is threatened to be made, a party to an action or proceeding, whether
civil or criminal, administrative or investigative, by reason of being a
director of the Registrant or a predecessor corporation of the Registrant, or is
or was serving at the request of the Registrant as a director or officer of
another corporation; provided, however, that the Registrant shall indemnify any
such agent in connection with a proceeding initiated by such agent only if such
proceeding was authorized by the Registrant's Board of Directors (the "Board").

                                      II-1
<Page>

The Bylaws further provide that such indemnification provisions shall: (i) not
be deemed to be exclusive of any other rights to which those indemnified may be
entitled under any bylaw, agreement or vote of stockholder or disinterested
directors or otherwise, both as to action in their official capacities and as to
action in another capacity while holding such office, (ii) continue as to a
person who has ceased to be a director, and (iii) inure to the benefit of the
heirs, executors and administrators of such a person. The Bylaws provide that
the Registrant's obligation to provide indemnification shall be offset to the
extent of any other source of indemnification or any otherwise applicable
insurance coverage under a policy maintained by the Registrant or any other
person. The Bylaws further provide that the Board in its discretion shall have
the power to indemnify any person, other than a director, made a party to any
action, suit or proceeding by reason of the fact that he, his testator or
intestate, is or was an officer or employee of the corporation.


      In addition, the Registrant's Certificate of Incorporation (the
"Certificate of Incorporation") provides that, pursuant to Delaware law, its
directors shall not be personally liable for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Registrant or its stockholders, (ii) for acts
or omissions not in good faith or involving intentional misconduct, (iii) for
knowing violations of law, (iv) for actions leading to improper personal benefit
to the director, and (v) for unlawful payments of dividends or unlawful stock
repurchases or redemptions as provided in Section 174 of Delaware General
Corporation Law.


      The Registrant maintains a directors' and officers' liability insurance
policy that, subject to certain limitations, terms and conditions, will insure
the directors and officers of the Registrant against losses arising from
wrongful acts (as defined by the policy) in his or her capacity as a director or
officer.

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
"1933 Act"), (ii) to reflect in the prospectus any facts or events arising
after the effective date of this 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 this
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

                                      II-2
<Page>

the estimated maximum offering range may be reflected in the form of prospectus
filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in
volume and price represent no more than 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
this Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall
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 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 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 upon the termination of the
Registrant's 1999 Stock Option/Stock Issuance Plan, as amended, the Registrant's
1997 Supplemental Stock Option Plan, as amended, or the Registrant's 1993
Employee Stock Purchase Plan, as amended.


      B.    The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act
(and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the 1934 Act) that is incorporated by
reference into this 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 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnity provisions summarized in Item 6 or
otherwise, the Registrant has been informed that in the opinion of the SEC
such indemnification is against public policy as expressed in the 1933 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 1933
Act and will be governed by the final adjudication of such issue.

Registration Statement to be signed on its behalf by the undersigned, thereunto
