        For purposes of this Registration Statement, any statement contained in
a document incorporated or deemed to be incorporated herein by reference shall
be deemed to be modified or superseded to the extent that a statement contained
herein or in any other subsequently filed document that also is or is deemed to
be incorporated herein by reference modifies or supersedes such statement in
such document.  Any statement so modified or superseded shall not be deemed,
except as so modified or superseded, to constitute a part of this Registration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 Company's Restated Certificate of Incorporation requires that
directors and officers be indemnified to the maximum extent permitted by
Delaware law.

        The General Corporation Law of the State of Delaware (the "Delaware
GCL") provides in general that a director or officer of a corporation (i) shall
be indemnified by the corporation for all expenses of litigation or other legal
proceedings when he is successful on the merits, (ii) may be indemnified by the
corporation for the expenses, judgments, fines and amounts paid in settlement of
such litigation (other than a derivative suit) even if he is not successful on
the merits if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation (and, in the case
of a criminal proceeding, had no reasonable cause to believe his conduct was
unlawful), and (iii) may be indemnified by the corporation for expenses of a
derivative suit (a suit by a stockholder alleging a breach by a director or
officer of a duty owed to the corporation), even if he is not successful on the
merits, if he acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the corporation, provided that no
such indemnification may be made in accordance with this clause (iii) if the
director or officer is adjudged liable to the corporation, unless a court
determines that, despite such adjudication but in view of all of the
circumstances, he is entitled to indemnification of such expenses.  The
indemnification described in clauses (ii) and (iii) above shall be made only
upon order by a court or a determination by (a) a majority of a quorum of
disinterested directors, (b) under certain circumstances, independent legal
counsel or (c) the stockholders, that indemnification is proper because the
applicable standard of conduct is met.  Expenses incurred by a director or
officer in defending an action may be advanced by the corporation prior to the
final disposition of such action upon receipt of an undertaking by such director
or officer to repay such expenses if it is ultimately determined that he is not
entitled to be indemnified in connection with the proceeding to which the
expenses related.

        The Company's Restated Certificate of Incorporation includes a provision
eliminating, to the fullest extent permitted by the Delaware GCL, director
liability for monetary damages for breaches of fiduciary duty.


                                       3


<PAGE>   4
        In order to provide indemnification beyond the specific provisions of
the Delaware GCL and the Company's Restated Certificate of Incorporation, the
Company has entered into Indemnity Agreements with each of its directors and
executive officers.  Absent the Indemnity Agreements, the indemnification that
might be available to directors and officers could be changed by amendments to
the Company's Restated Certificate of Incorporation.  The Indemnity Agreements
require that the Company indemnify directors and executive officers who are
parties thereto except to the extent such indemnification is prohibited by
applicable law and except with respect to claims where the director or officer
(i) received any personal profit or advantage to which he is not legally
entitled, (ii) is required to account for profits in fact made from the purchase
or sale of securities of the Company under Section 16(b) of the Securities Act
of 1934, or (iii) committed certain acts of dishonesty.

        The Company may seek directors and officers liability insurance against
the cost of defense, settlement or payment of a judgment under certain
circumstances.

Item 7. Exemption from Registration Claimed.

        Not applicable.

Item 8. Exhibits.

        4.1   Restated Certificate of Incorporation of the Company (filed as
              Exhibit 3.1 to the Company's Registration Statement on Form S-1

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;


                                       4
                                       
<PAGE>   5
                       (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;

                       (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
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.

        (b)     The undersigned registrant hereby undertakes that,
for purposes of determining any liability under the Securities Act of 1933,
each filing of the registrant's annual report pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) 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 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
Securities and Exchange Commission such indemnification is against public
policy as expressed in the 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 of whether such indemnification by it is against public policy as
expressed in the Act and will be governed by a final adjudication of such
issue.

                purpose of updating such description.

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

        For purposes of this Registration Statement, any statement contained in
a document incorporated or deemed to be incorporated herein by reference shall
be deemed to be modified or superseded to the extent that a statement contained

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 Company's Restated Certificate of Incorporation requires that
directors and officers be indemnified to the maximum extent permitted by
Delaware law.

        The General Corporation Law of the State of Delaware (the "Delaware
GCL") provides in general that a director or officer of a corporation (i) shall
be indemnified by the corporation for all expenses of litigation or other legal
proceedings when he is successful on the merits, (ii) may be indemnified by the
corporation for the expenses, judgments, fines and amounts paid in settlement of
such litigation (other than a derivative suit) even if he is not successful on
the merits if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation (and, in the case
of a criminal proceeding, had no reasonable cause to believe his conduct was
unlawful), and (iii) may be indemnified by the corporation for expenses of a
derivative suit (a suit by a stockholder alleging a breach by a director or
officer of a duty owed to the corporation), even if he is not successful on the
merits, if he acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the corporation, provided that no
such indemnification may be made in accordance with this clause (iii) if the
director or officer is adjudged liable to the corporation, unless a court
determines that, despite such adjudication but in view of all of the
circumstances, he is entitled to indemnification of such expenses.  The
indemnification described in clauses (ii) and (iii) above shall be made only
upon order by a court or a determination by (a) a majority of a quorum of
disinterested directors, (b) under certain circumstances, independent legal
counsel or (c) the stockholders, that indemnification is proper because the
applicable standard of conduct is met.  Expenses incurred by a director or
officer in defending an action may be advanced by the corporation prior to the
final disposition of such action upon receipt of an undertaking by such director
or officer to repay such expenses if it is ultimately determined that he is not
entitled to be indemnified in connection with the proceeding to which the
expenses related.

        The Company's Restated Certificate of Incorporation includes a provision
eliminating, to the fullest extent permitted by the Delaware GCL, director
liability for monetary damages for breaches of fiduciary duty.

                                       3
4
        In order to provide indemnification beyond the specific provisions of
the Delaware GCL and the Company's Restated Certificate of Incorporation, the
Company has entered into Indemnity Agreements with each of its directors and
executive officers.  Absent the Indemnity Agreements, the indemnification that
might be available to directors and officers could be changed by amendments to
the Company's Restated Certificate of Incorporation.  The Indemnity Agreements
require that the Company indemnify directors and executive officers who are
parties thereto except to the extent such indemnification is prohibited by
applicable law and except with respect to claims where the director or officer
(i) received any personal profit or advantage to which he is not legally
entitled, (ii) is required to account for profits in fact made from the purchase
or sale of securities of the Company under Section 16(b) of the Securities Act
of 1934, or (iii) committed certain acts of dishonesty.

        The Company may seek directors and officers liability insurance against
the cost of defense, settlement or payment of a judgment under certain
circumstances.

Item 7. Exemption from Registration Claimed.

        Not applicable.

Item 8. Exhibits.

        4.1   Restated Certificate of Incorporation of the Company (filed as

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;

                                       4
5
                       (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;

                       (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
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.

        (b)     The undersigned registrant hereby undertakes that,
for purposes of determining any liability under the Securities Act of 1933,
each filing of the registrant's annual report pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) 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 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
Securities and Exchange Commission such indemnification is against public
policy as expressed in the 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 of whether such indemnification by it is against public policy as
expressed in the Act and will be governed by a final adjudication of such
issue.
