          PART II.  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.     INCORPORATION OF DOCUMENTS BY REFERENCE

         The following documents, which are filed with the Securities and
Exchange Commission (the "Commission"), are incorporated in this Registration
Statement by reference:

         (a)     The Company's annual report on Form 10-K filed with the
Commission on March 31, 1999 (File No. 0-24531).

         (b)     All other reports filed by the Company pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), since December 31, 1998.

         (c)     The description of the common stock of the Company, $.01 par
value per share (the "Common Stock"), which is registered under Section 12 of
the Exchange Act, contained in the Registration Statement on Form 8-A filed
with the Commission on June 25, 1998, which incorporates by reference the
description of the Common Stock contained in the Registration Statement on Form
S-1 (No. 333-47953) (originally filed on March 13, 1998), as amended, including
any amendment or report filed for the purpose of updating such description.
Such description of the Common Stock contained in the Form S-1 is also
incorporated by reference.

         All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment which indicates that all shares of Common Stock
offered hereby have been sold or which deregisters all shares of Common Stock
then remaining unsold, shall be deemed to be incorporated by reference herein
and to be part hereof from the date of the filing of such documents.

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 Certificate of Incorporation provides that the
Registrant shall, subject to certain limitations, indemnify its directors and
officers against expenses (including attorneys' fees, judgments, fines and
certain settlements) actually and reasonably incurred by them in connection
with any suit or proceeding to which they are a party so long as they acted in
good faith and in a manner reasonably believed to be in or not opposed to the
best interests of the

<PAGE>   3

--------------------------------------------------------------------------------

corporation, and, with respect to a criminal action or proceeding, so long as
they had no reasonable cause to believe their conduct to have been unlawful.

         Section 102 of the Delaware General Corporation Law permits a Delaware
corporation to include in its certificate of incorporation a provision
eliminating or limiting a director's liability to a corporation or its
stockholders for monetary damages for breaches of fiduciary duty.  The enabling
statute provides, however, that liability for breaches of the duty of loyalty,
acts or omissions not in good faith or involving intentional misconduct, or
knowing violation of the law, and the unlawful purchase or redemption of stock
or payment of unlawful dividends or the receipt of improper personal benefits
cannot be eliminated or limited in this manner.  The Registrant's Certificate
of Incorporation includes a provision which eliminates, to the fullest extent
permitted, director liability for monetary damages for breaches of fiduciary
duty.

ITEM 7.     EXEMPTION FROM REGISTRATION CLAIMED

         Not applicable.

ITEM 8.     EXHIBITS

         The exhibits filed as a part of this registration statement are set
forth in the Exhibit Index.

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 date of this
                                     registration statement (or the most recent
                                     post-effective amendment hereto) which,
                                     individually or in the aggregate,
                                     represent a fundamental change in
                                     information set forth in this 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;

<PAGE>   4

--------------------------------------------------------------------------------

                             provided, however, that paragraphs (a)(1)(i) and
                             (a)(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 Exchange Act
                             that are incorporated by reference in this
                             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.

            (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 to the provisions set forth in Item 6, 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.

          PART II.  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.     INCORPORATION OF DOCUMENTS BY REFERENCE

         The following documents, which are filed with the Securities and
Exchange Commission (the "Commission"), are incorporated in this Registration
Statement by reference:

         (a)     The Company's annual report on Form 10-K filed with the
Commission on March 31, 1999 (File No. 0-24531).

         (b)     All other reports filed by the Company pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), since December 31, 1998.

         (c)     The description of the common stock of the Company, $.01 par
value per share (the "Common Stock"), which is registered under Section 12 of
the Exchange Act, contained in the Registration Statement on Form 8-A filed
with the Commission on June 25, 1998, which incorporates by reference the
description of the Common Stock contained in the Registration Statement on Form
S-1 (No. 333-47953) (originally filed on March 13, 1998), as amended, including
any amendment or report filed for the purpose of updating such description.
Such description of the Common Stock contained in the Form S-1 is also
incorporated by reference.

         All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment which indicates that all shares of Common Stock
offered hereby have been sold or which deregisters all shares of Common Stock
then remaining unsold, shall be deemed to be incorporated by reference herein
and to be part hereof from the date of the filing of such documents.

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 Certificate of Incorporation provides that the
Registrant shall, subject to certain limitations, indemnify its directors and
officers against expenses (including attorneys' fees, judgments, fines and
certain settlements) actually and reasonably incurred by them in connection
with any suit or proceeding to which they are a party so long as they acted in
good faith and in a manner reasonably believed to be in or not opposed to the
best interests of the
3

--------------------------------------------------------------------------------

corporation, and, with respect to a criminal action or proceeding, so long as
they had no reasonable cause to believe their conduct to have been unlawful.

         Section 102 of the Delaware General Corporation Law permits a Delaware
corporation to include in its certificate of incorporation a provision
eliminating or limiting a director's liability to a corporation or its
stockholders for monetary damages for breaches of fiduciary duty.  The enabling
statute provides, however, that liability for breaches of the duty of loyalty,
acts or omissions not in good faith or involving intentional misconduct, or
knowing violation of the law, and the unlawful purchase or redemption of stock
or payment of unlawful dividends or the receipt of improper personal benefits
cannot be eliminated or limited in this manner.  The Registrant's Certificate
of Incorporation includes a provision which eliminates, to the fullest extent
permitted, director liability for monetary damages for breaches of fiduciary
duty.

ITEM 7.     EXEMPTION FROM REGISTRATION CLAIMED

         Not applicable.

ITEM 8.     EXHIBITS

         The exhibits filed as a part of this registration statement are set
forth in the Exhibit Index.

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 date of this
                                     registration statement (or the most recent
                                     post-effective amendment hereto) which,
                                     individually or in the aggregate,
                                     represent a fundamental change in
                                     information set forth in this 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;
4

--------------------------------------------------------------------------------

                             provided, however, that paragraphs (a)(1)(i) and
                             (a)(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 Exchange Act
                             that are incorporated by reference in this
                             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.

            (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 to the provisions set forth in Item 6, 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.
