                  Act, in connection with the Company's Registration Statement
                  on Form S-1 (File No. 333-51523), in which there is set forth

         4.       The description of the Common Stock contained in the Company's
                  Registration Statement on Form 8-A filed with the Commission
                  on June 8, 1998 pursuant to Section 12 of the Securities
                  Exchange Act of 1934, as amended, (the "Exchange Act")
                  including any amendments or reports filed for the purpose of
                  updating such description.

              All documents filed by the Company with the Commission pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act after the date of this
Registration Statement and prior to the filing of a post-effective amendment
which indicates that all shares of Common Stock offered pursuant to this
Registration Statement have been sold or that de-registers all shares of Common

              The November 30, 1998, 1997 and 1996 consolidated financial
statements of the Company incorporated by reference in this Registration
Statement have been audited by McGladrey & Pullen, LLP, independent public

that McGladrey & Pullen, LLP audits and reports on the financial statements
of the Company issued at future dates, and consents to the use of their

said authority as experts.

<PAGE>

              Not Applicable.


ITEM 6.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

              The Company's Certificate of Incorporation limits the liability of
its directors to the fullest extent permitted under the Delaware General
Corporation Law. Specifically, directors of the Company will not be liable to
the Company or its stockholders for monetary damages for any breach of fiduciary
duty by such a director, except for liability for: any breach of the director's
duty of loyalty to the Company or its stockholders; acts or omissions not in
good faith or which involve intentional; misconduct or a knowing violation of
law; corporate distributions, including dividends, stock distributions and
redemptions, which are in contravention of restrictions in Delaware law, the
Company's Certificate of Incorporation or Bylaws, or any agreement to which the
Company is a party; and any transaction from which a director derives an
improper personal benefit.  This provision will generally not limit liability
under state or federal securities laws.

              Delaware law and the Company's Certificate of Incorporation
provide that the Company shall, under certain circumstances and subject to
certain limitations, indemnify any person made or threatened to be made a party
to a proceeding by reason of that person's former or present official capacity
with the Company against judgments, penalties, fines, settlements and reasonable
expenses. Any such person is also entitled, subject to certain limitations, to
payment or reimbursement of reasonable expenses in advance of the final
disposition of the proceeding.

              The Company has also entered into indemnification agreements with
all of its directors and executive officers. Under these agreements the Company
has agreed to indemnify and hold each harmless from and against any claims,
liability, damages or expenses incurred by them in or arising out of their
status, capacities and activities with respect to the Company to the maximum
extent permitted by Delaware law. The Company believes that these agreements are
necessary to attract and retain qualified persons as directors and executive
officers.

ITEM 7.       EXEMPTIONS FROM REGISTRATION CLAIMED.

              No securities are to be offered or resold pursuant to this

ITEM 9.       UNDERTAKINGS.

     (a)      The undersigned registrant hereby undertakes:


                                        2

<PAGE>

              (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 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) under
                               the Securities Act if, in the aggregate, the
                               changes in volume and price represent no more
                               than a 20% change in the maximum aggregate
                               offering price set forth in the "Calculation of
                               Registration  Fee" table in the effective
                               registration statement.

                      (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 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 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, 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 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


                                        3
<PAGE>

               liabilities (other than the payment by 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.

                  Act, in connection with the Company's Registration Statement
                  on Form S-1 (File No. 333-51523), in which there is set forth
                  the audited financial statements as of November 30, 1998 and

                  ended August 31, 1999 (File No. 333-51523); and

         4.       The description of the Common Stock contained in the Company's
                  Registration Statement on Form 8-A filed with the Commission
                  on June 8, 1998 pursuant to Section 12 of the Securities
                  Exchange Act of 1934, as amended, (the "Exchange Act")
                  including any amendments or reports filed for the purpose of
                  updating such description.

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

              The November 30, 1998, 1997 and 1996 consolidated financial
statements of the Company incorporated by reference in this Registration
Statement have been audited by McGladrey & Pullen, LLP, independent public
accountants, for the periods indicated in their report thereon which is
included in the Company's Registration Statement on Form S-1. Such
consolidated financial statements have been incorporated herein by reference
in reliance upon the report of McGladrey & Pullen, LLP, given on the
authority of that firm as experts in accounting and auditing. To the extent
that McGladrey & Pullen, LLP audits and reports on the financial statements
of the Company issued at future dates, and consents to the use of their
report thereon, such financial statements will also be incorporated by
reference in the Registration Statement in reliance upon their report and
said authority as experts.

ITEM 4.       DESCRIPTION OF SECURITIES.

              The Company's Common Stock to be offered pursuant to this
Registration Statement has been registered under Section 12 of the Exchange Act
as described in Item 3 of this Part II.

ITEM 5.       INTERESTS OF NAMED EXPERTS AND COUNSEL.
Not Applicable.

ITEM 6.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

              The Company's Certificate of Incorporation limits the liability of
its directors to the fullest extent permitted under the Delaware General
Corporation Law. Specifically, directors of the Company will not be liable to
the Company or its stockholders for monetary damages for any breach of fiduciary
duty by such a director, except for liability for: any breach of the director's
duty of loyalty to the Company or its stockholders; acts or omissions not in
good faith or which involve intentional; misconduct or a knowing violation of
law; corporate distributions, including dividends, stock distributions and
redemptions, which are in contravention of restrictions in Delaware law, the
Company's Certificate of Incorporation or Bylaws, or any agreement to which the
Company is a party; and any transaction from which a director derives an
improper personal benefit.  This provision will generally not limit liability
under state or federal securities laws.

              Delaware law and the Company's Certificate of Incorporation
provide that the Company shall, under certain circumstances and subject to
certain limitations, indemnify any person made or threatened to be made a party
to a proceeding by reason of that person's former or present official capacity
with the Company against judgments, penalties, fines, settlements and reasonable
expenses. Any such person is also entitled, subject to certain limitations, to
payment or reimbursement of reasonable expenses in advance of the final
disposition of the proceeding.

              The Company has also entered into indemnification agreements with
all of its directors and executive officers. Under these agreements the Company
has agreed to indemnify and hold each harmless from and against any claims,
liability, damages or expenses incurred by them in or arising out of their
status, capacities and activities with respect to the Company to the maximum
extent permitted by Delaware law. The Company believes that these agreements are
necessary to attract and retain qualified persons as directors and executive
officers.

ITEM 7.       EXEMPTIONS FROM REGISTRATION CLAIMED.

ITEM 9.       UNDERTAKINGS.

     (a)      The undersigned registrant hereby undertakes:

                                        2
(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 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) under
                               the Securities Act if, in the aggregate, the
                               changes in volume and price represent no more
                               than a 20% change in the maximum aggregate
                               offering price set forth in the "Calculation of
                               Registration  Fee" table in the effective
                               registration statement.

                      (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 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 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, 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 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

                                        3
liabilities (other than the payment by 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.

                                        4
