               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         The Company hereby incorporates by reference in this Prospectus the
Company's Annual Report on Form 10-K for the year ended March 31, 2001, the
Corporation's Quarterly Report on Form 10-Q for the quarter ended June 30, 2001,
the Corporation's Current Reports on Form 8-K filed July 19, August 13 and
October 4, 2001, and the description of the Common Stock contained in the
Company's registration statement for its Common Stock filed under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), including any amendment
or report filed for the purpose of updating such description.

         All documents subsequently filed by the Company pursuant to Section
13(a), 13(c), 14 or 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment that indicates that all securities offered have been
sold or that deregisters all securities 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. Any statement contained herein
or in a document all or a portion of which is 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incorporated by reference herein shall be deemed to be modified or superseded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 other subsequently filed document which also is or 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 Any such statement so modified or superseded shall not be deemed,
except as so modified or superseded, to constitute a part of this Registration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.

         The validity of the issuance of the shares of Common Stock offered
hereby will be passed upon for the Registrant by Steven D. Overly, Senior Vice
President, Administration, General Counsel and Secretary of the Registrant. Mr.
Overly is an employee of the Registrant. As of September 30, 2001, Mr. Overly
held 32,500 shares of Registrant's Common Stock and held options to purchase
153,000 shares of Common Stock (of which 37,167 shares are exercisable within
the next 60 days).

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Company's Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Section 145 of the
General Corporation Law of the State of Delaware authorizes and empowers each
Delaware corporation to indemnify its directors, officers, employees and agents
against liabilities incurred in connection with, and related expenses resulting
from, any claim, action or suit brought against any such person as a result of
his or her relationship with the Company, provided that such persons acted in
good faith and in a manner such person reasonably believed to be in, and not
opposed to, the best interests of the Company in connection with the acts or
events on which such claim, action or suit is based. The finding of either civil
or criminal liability on the part of such person in connection with such acts or
events is not necessarily determinative of the question of whether such person
has met the required standard of conduct and is, accordingly, entitled to be
indemnified. The foregoing statements are subject to the detailed provisions of
Section 145 of the General Corporation Law of the State of Delaware.

         The By-Laws of the Company provide that each person who at any time is
or was a director or officer of the Company, or is or was serving as director or
officer of another corporation, partnership, joint venture, trust or other
enterprise at the request of the Company or was a director or officer of a
corporation which was a predecessor corporation of the Company or of another
enterprise at the request of such predecessor corporation shall be indemnified
by the Company in accordance with and to the full extent permitted by the
General Corporation Law of the State of Delaware. Article VI of the By-Laws of
the Company facilitates enforcement of the right of directors and officers to be
indemnified by establishing such right as a contract right pursuant to which the
person entitled thereto may bring suit as if the indemnification provisions of
the By-Laws were set forth in a separate written contract between the Company
and the director or officer. Article VI of the By-Laws also permits the Company
to secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions in such capacity, regardless
of whether the Company would have the power to indemnify him or her against such
liability

<PAGE>   3

under the General Corporation Law of Delaware. The Company currently has secured
such insurance on behalf of its officers and directors.

         The Company has entered into agreements to indemnify its directors and
officers, in addition to indemnification provided for in the Company's By-Laws.
Subject to certain conditions, these agreements, among other things, indemnify
the Company's directors and officers for certain expenses (including attorney's
fees), judgments, fines and settlement amounts incurred by any such person in
any action or proceedings, including any action by or in the right of the
Company, arising out of such person's services as a director or officer of the
Company, any subsidiary of the Company or any other company or enterprise to
which the person provides services at the request of the Company.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 9. UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

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

              (i) to include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933;

              (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

                                      II-2
<PAGE>   4

         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% 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 (1)(i) and (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
Securities Exchange Act of 1934 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; and

         (4) that, for purposes of determining any liability under the
     Securities Act of 1933, each filing of Registrant's annual report pursuant
     to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is
     incorporated by reference in 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.

         The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 of
1933 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 of 1933 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 Company hereby incorporates by reference in this Prospectus the
Company's Annual Report on Form 10-K for the year ended March 31, 2001, the
Corporation's Quarterly Report on Form 10-Q for the quarter ended June 30, 2001,
the Corporation's Current Reports on Form 8-K filed July 19, August 13 and
October 4, 2001, and the description of the Common Stock contained in the
Company's registration statement for its Common Stock filed under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), including any amendment
or report filed for the purpose of updating such description.

         All documents subsequently filed by the Company pursuant to Section
13(a), 13(c), 14 or 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment that indicates that all securities offered have been
sold or that deregisters all securities 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. Any statement contained herein
or in a document all or a portion of which is 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 other subsequently filed document which also is or 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.

         The validity of the issuance of the shares of Common Stock offered
hereby will be passed upon for the Registrant by Steven D. Overly, Senior Vice
President, Administration, General Counsel and Secretary of the Registrant. Mr.
Overly is an employee of the Registrant. As of September 30, 2001, Mr. Overly
held 32,500 shares of Registrant's Common Stock and held options to purchase
153,000 shares of Common Stock (of which 37,167 shares are exercisable within
the next 60 days).

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Company's Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Section 145 of the
General Corporation Law of the State of Delaware authorizes and empowers each
Delaware corporation to indemnify its directors, officers, employees and agents
against liabilities incurred in connection with, and related expenses resulting
from, any claim, action or suit brought against any such person as a result of
his or her relationship with the Company, provided that such persons acted in
good faith and in a manner such person reasonably believed to be in, and not
opposed to, the best interests of the Company in connection with the acts or
events on which such claim, action or suit is based. The finding of either civil
or criminal liability on the part of such person in connection with such acts or
events is not necessarily determinative of the question of whether such person
has met the required standard of conduct and is, accordingly, entitled to be
indemnified. The foregoing statements are subject to the detailed provisions of
Section 145 of the General Corporation Law of the State of Delaware.

         The By-Laws of the Company provide that each person who at any time is
or was a director or officer of the Company, or is or was serving as director or
officer of another corporation, partnership, joint venture, trust or other
enterprise at the request of the Company or was a director or officer of a
corporation which was a predecessor corporation of the Company or of another
enterprise at the request of such predecessor corporation shall be indemnified
by the Company in accordance with and to the full extent permitted by the
General Corporation Law of the State of Delaware. Article VI of the By-Laws of
the Company facilitates enforcement of the right of directors and officers to be
indemnified by establishing such right as a contract right pursuant to which the
person entitled thereto may bring suit as if the indemnification provisions of
the By-Laws were set forth in a separate written contract between the Company
and the director or officer. Article VI of the By-Laws also permits the Company
to secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions in such capacity, regardless
of whether the Company would have the power to indemnify him or her against such
liability
3

under the General Corporation Law of Delaware. The Company currently has secured
such insurance on behalf of its officers and directors.

         The Company has entered into agreements to indemnify its directors and
officers, in addition to indemnification provided for in the Company's By-Laws.
Subject to certain conditions, these agreements, among other things, indemnify
the Company's directors and officers for certain expenses (including attorney's
fees), judgments, fines and settlement amounts incurred by any such person in
any action or proceedings, including any action by or in the right of the
Company, arising out of such person's services as a director or officer of the
Company, any subsidiary of the Company or any other company or enterprise to
which the person provides services at the request of the Company.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9. UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

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

              (i) to include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933;

              (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

                                      II-2
4

         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% 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 (1)(i) and (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
Securities Exchange Act of 1934 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; and

         (4) that, for purposes of determining any liability under the
     Securities Act of 1933, each filing of Registrant's annual report pursuant
     to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is
     incorporated by reference in 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.

         The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 of
1933 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 of 1933 and will be governed by the final adjudication of such issue.
