Item 4.  Description of Securities

  Not Applicable.

Item 5.  Interests of Named Experts and Counsel

  Not Applicable.

Item 6.  Indemnification of Directors and Officers

Limitation of Liability of Directors.

  The Company's Certificate of Incorporation provides that a director of the
Company will not be personally liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability (1) for any breach of the director's duty of loyalty to the Company or
its stockholders, (2) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (3) under Section 174 of
the General Corporation Law of the State of Delaware (the "DGCL"), which
concerns unlawful payments of dividends, stock purchases or redemptions, or (4)
for any transaction from which the director derived an improper personal
benefit.

                                     II-1
<PAGE>

  While the Company's Certificate of Incorporation provides directors with
protection from awards for monetary damages for breaches of their duty of care,
it does not eliminate such duty.  Accordingly, the Company's Certificate of
Incorporation will have no effect on the availability of equitable remedies such
as an injunction or rescission based on a director's breach of his or her duty
of care.  The provisions of the Company's Certificate of Incorporation described
above apply to an officer of the Company only if he or she is a director of the
Company and is acting in his or her capacity as director, and do not apply to
officers of the Company who are not directors.

Indemnification of Directors and Officers.

  The Company's Certificate of Incorporation provides that each person who is or
was or had agreed to become a director or officer of the Company, or each such
person who is or was serving or who had agreed to serve at the request of the
Company as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise (including the heirs, executors,
administrators or estate of such person), will be indemnified by the Company, in
accordance with the Company's Bylaws, to the fullest extent permitted from time
to time by the DGCL, as the same exists or may hereafter be amended (but, if
permitted by applicable law, in the case of any such amendment, only to the
extent that such amendment permits the Company to provide broader
indemnification rights than said law permitted the Company to provide prior to
such amendment) or any other applicable laws as presently or hereafter in
effect. The Company may, by action of the Company's Board of Directors, provide
indemnification to employees and agents of the Company, and to persons serving
as employees or agents of another corporation, partnership, joint venture, trust
or other enterprise, at the request of the Company, with the same scope and
effect as the foregoing indemnification of directors and officers. The Company
may be required to indemnify any person seeking indemnification in connection
with a proceeding (or part thereof) initiated by such person only if such
proceeding (or part thereof) was authorized by the Company's Board of Directors
or is a proceeding to enforce such person's claim to indemnification pursuant to
the rights granted by the Company's Certificate of Incorporation or otherwise by
the Company.

  The Company's Bylaws provide that each person who was or is made a party or is
threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of the fact that he or she or a person of whom he or
she is the legal representative is or was a director or officer of the Company
or is or was serving at the request of the Company as a director or officer of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, whether
the basis of such Proceeding is alleged action in an official capacity as a
director or officer or in any other capacity while serving as a director or
officer, will be indemnified and held harmless by the Company to the fullest
extent authorized by the DGCL as the same exists or may in the future be amended
(but, if permitted by applicable law, in the case of any such amendment, only to
the extent that such amendment permits the Company to provide broader
indemnification rights than said law permitted the Company to provide prior to
such amendment), against all expense, liability and loss (including attorneys'
fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to
be paid in settlement) reasonably incurred or suffered by such person in
connection therewith and such indemnification will continue as to a person who
has ceased to be a director or officer and will inure to the benefit of his or
her heirs, executors and administrators; provided, however, except as described
in the second following paragraph with respect to Proceedings to enforce rights
to indemnification, the Company will indemnify any such person seeking
indemnification in connection with a Proceeding (or part thereof) initiated by
such person only if such Proceeding (or part thereof) was authorized by the
Company's Board of Directors.

  Pursuant to the Company's Bylaws, to obtain indemnification, a claimant is to
submit to the Company a written request for indemnification.  Upon such written
request by a claimant, a determination, if required by applicable law, with
respect to the claimant's entitlement to indemnification will be made, if
requested by the claimant, by independent legal counsel, or if the claimant does
not so request, by the Company's Board of Directors by a majority vote of the
disinterested directors even though less than a quorum or, if there are no
disinterested directors or the disinterested directors so direct, by independent
legal counsel in a written opinion to the Company's Board of Directors, or if
the disinterested directors so direct, by the stockholders of the Company.  In
the event the determination of entitlement to indemnification is to be made by
independent legal counsel at the request of the claimant, the independent legal
counsel will be selected by the Company's Board of Directors unless there has
occurred within two years prior to the date of the commencement of the action,
suit or proceeding for which indemnification is claimed a change of control, in
which case the independent legal counsel will be selected by the claimant unless
the claimant requests that such selection be made by the Company's Board of
Directors.

                                     II-2
<PAGE>

  Pursuant to the Company's Bylaws, if a claim described in the preceding
paragraph is not paid in full by the Company within thirty days after a written
claim pursuant to the preceding paragraph has been received by the Company, the
claimant may at any time thereafter bring suit against the Company to recover
the unpaid amount of the claim and, if successful in whole or in part, the
claimant will also be entitled to be paid the expense of prosecuting such claim.
The Company's Bylaws provide that it will be a defense to any such action (other
than an action brought to enforce a claim for expenses incurred in defending any
Proceeding in advance of its final disposition where the required undertaking,
if any is required, has been tendered to the Company) that the claimant has not
met the standard of conduct which makes it permissible under the DGCL for the
Company to indemnify the claimant for the amount claimed, but the burden of
proving such defense will be on the Company.  Neither the failure of the Company
(including the disinterested directors, independent legal counsel or
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
DGCL, nor an actual determination by the Company (including the disinterested
directors, independent legal counsel or stockholders) that the claimant has not
met such applicable standard of conduct, will be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.  However, the Company will be precluded from asserting that the
procedures and presumptions set forth in the Company's Bylaws are not valid,
binding and enforceable and will  be bound by a determination pursuant to the
procedures set forth in the Company's Bylaws that the claimant is entitled to
indemnification in any suit brought by a claimant pursuant to the Company's
Bylaws.

  The Company's Bylaws provide that the right to indemnification and the payment
of expenses incurred in defending a Proceeding in advance of its final
disposition conferred in the Company's Bylaws will not be exclusive of any other
right which any person may have or may in the future acquire under any statute,
provision of the Company's Certificate of Incorporation, the Company's Bylaws,
agreement, vote of stockholders or disinterested directors or otherwise.  The
Company's Bylaws permit the Company to maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of the Company or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the Company would have
the power to indemnify such person against such expense, liability or loss under
the DGCL.  In addition, the Company's Bylaws authorize the Company, to the
extent authorized from time to time by the Company's Board of Directors, to
grant rights to indemnification and rights to be paid by the Company the
expenses incurred in defending any Proceeding in advance of its final
disposition to any employee or agent of the Company to the fullest extent of the
provisions of the Company's Bylaws with respect to the indemnification and
advancement of expenses of directors and officers of the Company.

  The Company's Bylaws provide that the right to indemnification conferred
therein is a contract right and includes the right to be paid by the Company the
expenses incurred in defending any Proceeding in advance of its final
disposition, except that if the DGCL requires, the payment of such expenses
incurred by a director or officer in his or her capacity as a director or
officer (and not in any other capacity in which service was or is rendered by
such person while a director or officer, including, without limitation, service
to an employee benefit plan) in advance of the final disposition of a
Proceeding, will be made only upon delivery to the Company of an undertaking by
or on behalf of such director or officer, to repay all amounts so advanced if it
is ultimately determined that such director of officer is not entitled to be
indemnified under the Company's Bylaws or otherwise.

  The Company has entered into indemnification agreements with each of its
directors and executive officers that contractually provide for indemnification
and expense advancement and include related provisions meant to facilitate the
indemnitees' receipt of such benefits.  These provisions cover, among other
things:  (i) specification of the method of determining entitlement to
indemnification and the selection of independent counsel that will in some cases
make such determination; (ii) specification of certain time periods by which
certain payments or determinations must be made and actions must be taken; and
(iii) the establishment of certain presumptions in favor of an indemnitee.  The
benefits of certain of these provisions are available to an indemnitee only if
there has been a change in control (as defined).

  The Company currently has directors' and officers' insurance that insures
directors and officers of the Company with respect to claims made for alleged
"wrongful acts" in their roles as directors or officers of the Company and its
subsidiaries.  The insurance also insures the Company for claims against the
Company's directors or officers in situations in which the Company has an
obligation to defend and/or indemnify its directors and officers.

Item 9.  Undertakings

  (a)  The Company 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;

           (ii) To reflect in the prospectus any facts or events arising after
     the effective date of this 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) of the Securities Act of 1933 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

                                     II-4
<PAGE>

          (iii)  To include any material information with respect to the plan of
     distribution not previously disclosed in this registration statement or any
     material change to such information in this registration statement;

  provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and
  (a)(1)(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 by the registrant pursuant to Section 13 or Section 15(d) of the
  Securities Exchange Act of 1934 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; and

     (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 Section 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 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.

  (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 provisions described under Item 6 above, 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 of 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.

Item 4.  Description of Securities

  Not Applicable.

Item 5.  Interests of Named Experts and Counsel

  Not Applicable.

Item 6.  Indemnification of Directors and Officers

Limitation of Liability of Directors.

  The Company's Certificate of Incorporation provides that a director of the
Company will not be personally liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability (1) for any breach of the director's duty of loyalty to the Company or
its stockholders, (2) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (3) under Section 174 of
the General Corporation Law of the State of Delaware (the "DGCL"), which
concerns unlawful payments of dividends, stock purchases or redemptions, or (4)
for any transaction from which the director derived an improper personal
benefit.

                                     II-1
While the Company's Certificate of Incorporation provides directors with
protection from awards for monetary damages for breaches of their duty of care,
it does not eliminate such duty.  Accordingly, the Company's Certificate of
Incorporation will have no effect on the availability of equitable remedies such
as an injunction or rescission based on a director's breach of his or her duty
of care.  The provisions of the Company's Certificate of Incorporation described
above apply to an officer of the Company only if he or she is a director of the
Company and is acting in his or her capacity as director, and do not apply to
officers of the Company who are not directors.

Indemnification of Directors and Officers.

  The Company's Certificate of Incorporation provides that each person who is or
was or had agreed to become a director or officer of the Company, or each such
person who is or was serving or who had agreed to serve at the request of the
Company as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise (including the heirs, executors,
administrators or estate of such person), will be indemnified by the Company, in
accordance with the Company's Bylaws, to the fullest extent permitted from time
to time by the DGCL, as the same exists or may hereafter be amended (but, if
permitted by applicable law, in the case of any such amendment, only to the
extent that such amendment permits the Company to provide broader
indemnification rights than said law permitted the Company to provide prior to
such amendment) or any other applicable laws as presently or hereafter in
effect. The Company may, by action of the Company's Board of Directors, provide
indemnification to employees and agents of the Company, and to persons serving
as employees or agents of another corporation, partnership, joint venture, trust
or other enterprise, at the request of the Company, with the same scope and
effect as the foregoing indemnification of directors and officers. The Company
may be required to indemnify any person seeking indemnification in connection
with a proceeding (or part thereof) initiated by such person only if such
proceeding (or part thereof) was authorized by the Company's Board of Directors
or is a proceeding to enforce such person's claim to indemnification pursuant to
the rights granted by the Company's Certificate of Incorporation or otherwise by
the Company.

  The Company's Bylaws provide that each person who was or is made a party or is
threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of the fact that he or she or a person of whom he or
she is the legal representative is or was a director or officer of the Company
or is or was serving at the request of the Company as a director or officer of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, whether
the basis of such Proceeding is alleged action in an official capacity as a
director or officer or in any other capacity while serving as a director or
officer, will be indemnified and held harmless by the Company to the fullest
extent authorized by the DGCL as the same exists or may in the future be amended
(but, if permitted by applicable law, in the case of any such amendment, only to
the extent that such amendment permits the Company to provide broader
indemnification rights than said law permitted the Company to provide prior to
such amendment), against all expense, liability and loss (including attorneys'
fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to
be paid in settlement) reasonably incurred or suffered by such person in
connection therewith and such indemnification will continue as to a person who
has ceased to be a director or officer and will inure to the benefit of his or
her heirs, executors and administrators; provided, however, except as described
in the second following paragraph with respect to Proceedings to enforce rights
to indemnification, the Company will indemnify any such person seeking
indemnification in connection with a Proceeding (or part thereof) initiated by
such person only if such Proceeding (or part thereof) was authorized by the
Company's Board of Directors.

  Pursuant to the Company's Bylaws, to obtain indemnification, a claimant is to
submit to the Company a written request for indemnification.  Upon such written
request by a claimant, a determination, if required by applicable law, with
respect to the claimant's entitlement to indemnification will be made, if
requested by the claimant, by independent legal counsel, or if the claimant does
not so request, by the Company's Board of Directors by a majority vote of the
disinterested directors even though less than a quorum or, if there are no
disinterested directors or the disinterested directors so direct, by independent
legal counsel in a written opinion to the Company's Board of Directors, or if
the disinterested directors so direct, by the stockholders of the Company.  In
the event the determination of entitlement to indemnification is to be made by
independent legal counsel at the request of the claimant, the independent legal
counsel will be selected by the Company's Board of Directors unless there has
occurred within two years prior to the date of the commencement of the action,
suit or proceeding for which indemnification is claimed a change of control, in
which case the independent legal counsel will be selected by the claimant unless
the claimant requests that such selection be made by the Company's Board of
Directors.

                                     II-2
Pursuant to the Company's Bylaws, if a claim described in the preceding
paragraph is not paid in full by the Company within thirty days after a written
claim pursuant to the preceding paragraph has been received by the Company, the
claimant may at any time thereafter bring suit against the Company to recover
the unpaid amount of the claim and, if successful in whole or in part, the
claimant will also be entitled to be paid the expense of prosecuting such claim.
The Company's Bylaws provide that it will be a defense to any such action (other
than an action brought to enforce a claim for expenses incurred in defending any
Proceeding in advance of its final disposition where the required undertaking,
if any is required, has been tendered to the Company) that the claimant has not
met the standard of conduct which makes it permissible under the DGCL for the
Company to indemnify the claimant for the amount claimed, but the burden of
proving such defense will be on the Company.  Neither the failure of the Company
(including the disinterested directors, independent legal counsel or
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
DGCL, nor an actual determination by the Company (including the disinterested
directors, independent legal counsel or stockholders) that the claimant has not
met such applicable standard of conduct, will be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.  However, the Company will be precluded from asserting that the
procedures and presumptions set forth in the Company's Bylaws are not valid,
binding and enforceable and will  be bound by a determination pursuant to the
procedures set forth in the Company's Bylaws that the claimant is entitled to
indemnification in any suit brought by a claimant pursuant to the Company's
Bylaws.

  The Company's Bylaws provide that the right to indemnification and the payment
of expenses incurred in defending a Proceeding in advance of its final
disposition conferred in the Company's Bylaws will not be exclusive of any other
right which any person may have or may in the future acquire under any statute,
provision of the Company's Certificate of Incorporation, the Company's Bylaws,
agreement, vote of stockholders or disinterested directors or otherwise.  The
Company's Bylaws permit the Company to maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of the Company or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the Company would have
the power to indemnify such person against such expense, liability or loss under
the DGCL.  In addition, the Company's Bylaws authorize the Company, to the
extent authorized from time to time by the Company's Board of Directors, to
grant rights to indemnification and rights to be paid by the Company the
expenses incurred in defending any Proceeding in advance of its final
disposition to any employee or agent of the Company to the fullest extent of the
provisions of the Company's Bylaws with respect to the indemnification and
advancement of expenses of directors and officers of the Company.

  The Company's Bylaws provide that the right to indemnification conferred
therein is a contract right and includes the right to be paid by the Company the
expenses incurred in defending any Proceeding in advance of its final
disposition, except that if the DGCL requires, the payment of such expenses
incurred by a director or officer in his or her capacity as a director or
officer (and not in any other capacity in which service was or is rendered by
such person while a director or officer, including, without limitation, service
to an employee benefit plan) in advance of the final disposition of a
Proceeding, will be made only upon delivery to the Company of an undertaking by
or on behalf of such director or officer, to repay all amounts so advanced if it
is ultimately determined that such director of officer is not entitled to be
indemnified under the Company's Bylaws or otherwise.

  The Company has entered into indemnification agreements with each of its
directors and executive officers that contractually provide for indemnification
and expense advancement and include related provisions meant to facilitate the
indemnitees' receipt of such benefits.  These provisions cover, among other
things:  (i) specification of the method of determining entitlement to
indemnification and the selection of independent counsel that will in some cases
make such determination; (ii) specification of certain time periods by which
certain payments or determinations must be made and actions must be taken; and
(iii) the establishment of certain presumptions in favor of an indemnitee.  The
benefits of certain of these provisions are available to an indemnitee only if
there has been a change in control (as defined).

  The Company currently has directors' and officers' insurance that insures
directors and officers of the Company with respect to claims made for alleged
"wrongful acts" in their roles as directors or officers of the Company and its
subsidiaries.  The insurance also insures the Company for claims against the
Company's directors or officers in situations in which the Company has an
obligation to defend and/or indemnify its directors and officers.

  post-effective amendment to this registration statement:

           (i)  To include any prospectus required by Section 10(a)(3) of the

  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
  Securities Exchange Act of 1934 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; and

     (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 Section 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 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.

  (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 provisions described under Item 6 above, 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 of 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.
