         (6)  All other reports filed by the Company pursuant to Section 13(a)
or Section 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), since December 31, 1998, the end of the Company's most recently
completed fiscal year for which an Annual Report on Form 10-K was filed.

         (7)  The description of the common stock of the Company (the "Common
Stock") contained in the Company's Registration Statement on Form 8-A, filed
October 21, 1995.

         (8)  All documents subsequently filed by the Company with the
Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act and
prior to the filing of a post-effective amendment which indicates that all
securities offered have been sold or which 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 any 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superseded for purposes of this registration statement to the extent that a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 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 Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this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 registered
hereby (the "Shares") has been passed upon for the Company by Steven J.
Udicious, Acting General Counsel of the Company. Mr. Udicious holds stock and
options to purchase stock granted under the Company's employee stock plans which
in the aggregate represent less than 1% of the Common Stock.

Item 6.  Indemnification of Directors and Officers.

         The Company is a Delaware corporation. Section 145 of the Delaware
General Corporation Law provides that a Delaware corporation may indemnify any
person against expenses, judgments, fines and settlements actually and
reasonably incurred by any such person in connection with a threatened, pending
or completed action, suit or proceeding in which such person is involved by
reason of the fact that he or she is or was a director, officer,

                                     II-1

<PAGE>

employee or agent of such corporation, provided that (i) such person acted in
good faith and in a manner reasonably believed to be in or not opposed to the
best interests of the corporation and (ii) with respect to any criminal action
or proceeding, such person had no reasonable cause to believe his or her conduct
was unlawful. If the action or suit is by or in the name of the corporation, the
corporation may indemnify any such person against expenses actually and
reasonably incurred by him or her in connection with the defense or settlement
of such action or suit if such person acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification may be made in respect to any claim,
issue or matter as to which such person shall have been adjudged to be liable to
the corporation unless and only to the extent that the Delaware Court of
Chancery or the court in which the action or suit is brought determines upon
application that, despite the adjudication of liability but in view of all of
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses as the court deems proper.

     Article XI, Section 1 of the Company's By-Laws provides for indemnification
of persons to the fullest extent permitted by the Delaware General Corporation
Law.

     In accordance with the Delaware General Corporation Law, the Company's
Certificate of Incorporation, as amended, limits the personal liability of its
directors for violations of their fiduciary duty.  The Certificate of
Incorporation eliminates each director's liability to the Company or its
stockholders for monetary damages except (i) for any breach of the director's
duty of loyalty to the Company or its stockholders, (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) under Section 174 of the Delaware General Corporation Law
providing for liability of directors for unlawful payment of dividends or
unlawful stock purchases or redemptions, or (iv) for any transaction from which
a director derived an improper benefit.  The effect of this provision is to
eliminate the personal liability of directors for monetary damages for actions
involving a breach of their fiduciary duty of care, including any such actions
involving gross negligence. This provision will not, however, limit in any way
the liability of directors for violations of the federal securities laws.

Item 7.   Exemptions 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 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;

       (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 (i) and (ii) above 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.

         (4)  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.

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