     Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article 11 of Cypress's Certificate of Incorporation provides that, to the
fullest extent permitted by Delaware law, as the same now exists or may
hereafter be amended, a director shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director. Delaware law provides that directors of a corporation will
not be personally liable for monetary damages for breach of their fiduciary
duties as directors, except for liability (i) for any breach of their duty of
loyalty to the corporation or its stockholders, (ii) for acts or omissions not
in good faith or that involve intentional misconduct or a knowing violation of
law, (iii) for unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the Delaware General Corporation Law,
or (iv) for any transaction from which the director derived an improper personal
benefit.

     Article VI of Cypress's Bylaws provides that Cypress (i) shall indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director or
officer of the corporation, or is or was serving at the request of the
corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, and (ii) may indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
contemplated action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was an employee or agent of the corporation, or
is or was serving at the request of the corporation as an employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding 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, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The Bylaws provide that
the termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interest of the corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

     Article VI of Cypress's Bylaws also provides that Cypress (1) shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director or officer of the corporation, or is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, and (2) may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor 


                                      -3-

<PAGE>   4

by reason of the fact that he is or was an employee or agent of the corporation,
or is or was serving at the request of the corporation as an employee or agent
of another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit 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 except that no indemnification
shall be made in respect of 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 such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Delaware
Court of Chancery or such other court shall deem proper.

     The Bylaws further provide that, to the extent that a director or officer
of the corporation has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to above, or in defense of any claim,
issue or matter therein, he shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection therewith
and to the extent that an employee or agent of the corporation has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred to above, or in defense of any claim, issue or matter
therein, he may be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

     Cypress's Bylaws also permit Cypress 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 Bylaws would permit
indemnification. Cypress currently maintains liability insurance for its
officers and directors.

     Cypress has entered into agreements to indemnify its directors and
officers, in addition to the indemnification provided for in Cypress's
Certificate of Incorporation and Bylaws. These agreements, among other things,
indemnify Cypress'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 proceeding, including any action by or in the right of
Cypress, arising out of such person's services as a director or officer of
Cypress, any subsidiary of Cypress or any other company or enterprise to which
the person provides services at the request of Cypress.

ITEM 9. UNDERTAKINGS.

     (a)  The 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 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.

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, as amended (the ASecurities 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 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
into 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 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 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 and will be governed by the final
adjudication of such issue.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article 11 of Cypress's Certificate of Incorporation provides that, to the
fullest extent permitted by Delaware law, as the same now exists or may
hereafter be amended, a director shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director. Delaware law provides that directors of a corporation will
not be personally liable for monetary damages for breach of their fiduciary
duties as directors, except for liability (i) for any breach of their duty of
loyalty to the corporation or its stockholders, (ii) for acts or omissions not
in good faith or that involve intentional misconduct or a knowing violation of
law, (iii) for unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the Delaware General Corporation Law,
or (iv) for any transaction from which the director derived an improper personal
benefit.

     Article VI of Cypress's Bylaws provides that Cypress (i) shall indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director or
officer of the corporation, or is or was serving at the request of the
corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, and (ii) may indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
contemplated action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was an employee or agent of the corporation, or
is or was serving at the request of the corporation as an employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding 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, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The Bylaws provide that
the termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interest of the corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

     Article VI of Cypress's Bylaws also provides that Cypress (1) shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director or officer of the corporation, or is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, and (2) may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor 

                                      -3-

by reason of the fact that he is or was an employee or agent of the corporation,
or is or was serving at the request of the corporation as an employee or agent
of another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit 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 except that no indemnification
shall be made in respect of 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 such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Delaware
Court of Chancery or such other court shall deem proper.

     The Bylaws further provide that, to the extent that a director or officer
of the corporation has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to above, or in defense of any claim,
issue or matter therein, he shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection therewith
and to the extent that an employee or agent of the corporation has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred to above, or in defense of any claim, issue or matter
therein, he may be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

     Cypress's Bylaws also permit Cypress 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 Bylaws would permit
indemnification. Cypress currently maintains liability insurance for its
officers and directors.

     Cypress has entered into agreements to indemnify its directors and
officers, in addition to the indemnification provided for in Cypress's
Certificate of Incorporation and Bylaws. These agreements, among other things,
indemnify Cypress'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 proceeding, including any action by or in the right of
Cypress, arising out of such person's services as a director or officer of
Cypress, any subsidiary of Cypress or any other company or enterprise to which
the person provides services at the request of Cypress.

ITEM 9. UNDERTAKINGS.

     (a)  The 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 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.

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, as amended (the ASecurities 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 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
into 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 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 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 and will be governed by the final
adjudication of such issue.
