ITEM 4. DESCRIPTION OF SECURITIES.

               Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

               Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Section 145(a) of the Delaware General Corporation Law (the "GCL")
provides that a Delaware corporation 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, 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 such person is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, 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 such person in connection with such action, suit or proceeding if he
or she 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, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.

        Section 145(b) of the GCL provides that a Delaware corporation 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 by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by such person in
connection with the defense or settlement of such action or suit if he or she
acted under similar standards, except that no indemnification may 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
court in which such action or suit was brought shall determine that despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to be indemnified for such expenses
which the court shall deem proper.

        Section 145 of the GCL further provides that to the extent a present or
former director or officer of a corporation has been successful in the defense
of any action, suit or proceeding referred to in subsection (a) and (b) or in
the defense of any claim, issue or matter therein, such person shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection therewith; that indemnification provided
for by Section 145 shall not be deemed exclusive of any other rights to which
the indemnified party may be entitled; and that the corporation may purchase and
maintain insurance on behalf of a director or officer of the corporation against
any liability asserted against such officer or director and incurred by him or
her in any such capacity or arising out of his or her status as such, whether or
not the corporation would have the power to indemnify him or her against such
liabilities under Section 145.

        As permitted by Section 102(b)(7) of the GCL, the Company's Certificate
of Incorporation provides that a director shall not be liable to the Company or
its stockholders for monetary damages for breach of fiduciary duty as a
director. However, such provision does not eliminate or limit the liability of a
director for acts or omissions not in good faith or for breaching his or her
duty of loyalty, engaging in intentional misconduct or knowingly violating a
law, paying a dividend or approving a stock repurchase which was illegal, or
obtaining an improper personal benefit.

        The Company's Certificate of Incorporation also requires that directors
and officers be indemnified to the maximum extent permitted by Delaware law. The
Company has entered into indemnity agreements with each of its directors and
executive officers. These indemnity agreements require that the Company pay on
behalf of each director and officer party thereto any amount that he or she is
or becomes legally obligated to pay because of any claim or claims made against
him or her because of any act or omission or neglect or breach of duty,
including any actual or alleged error or misstatement or misleading statement,
which he or she commits or suffers while acting in his or her capacity as a
director and/or officer of the Company and solely because of his or her being a
director 


                                       3

and/or officer. Under the GCL, absent such an indemnity agreement,
indemnification of a director or officer is discretionary rather than mandatory
(except in the case of a proceeding in which a director or officer is successful
on the merits). Consistent with the Company's Bylaw provision on the subject,
the indemnity agreements require the Company to make prompt payment of defense
and investigation costs and expenses at the request of the director or officer
in advance of indemnification, provided that the recipient undertakes to repay
the amounts if it is ultimately determined that he or she is not entitled to
indemnification for such expenses and provided further that such advance shall
not be made if it is determined that the director or officer acted in bad faith
or deliberately breached his or her duty to the Company or its stockholders and,
as a result, it is more likely than not that it will ultimately be determined
that he or she is not entitled to indemnification under the terms of the
indemnity agreement. The indemnity agreements make the advance of litigation
expenses mandatory absent a special determination to the contrary, whereas under
the GCL absent such an indemnity agreement, such advance would be discretionary.
Under the indemnity agreement, the director or officer is permitted to petition
the court to seek recovery of amounts due under the indemnity agreement and to
recover the expenses of seeking such recovery if he or she is successful.
Without the indemnity agreement, the Company would not be required to pay or
reimburse the director or officer for his or her expenses in seeking
indemnification recovery against the Company. By the terms of the indemnity
agreement, its benefits are not available if the director or officer has other
indemnification or insurance coverage for the subject claim or, with respect to
the matters giving rise to the claim, (i) received a personal benefit, (ii)
violated section 16(b) of the Securities Exchange Act of 1934 or analogous
provisions of law, or (iii) committed certain acts of dishonesty. Absent the
indemnity agreement, indemnification that might be made available to directors
and officers could be changed by amendments to the Company's Certificate of
Incorporation or Bylaws.

        The Company has a policy of directors and officers liability insurance
that insures the Company and its directors and officers against damages,
settlements, and defense costs under certain circumstances.

ITEM 4. DESCRIPTION OF SECURITIES.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

               Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Section 145(a) of the Delaware General Corporation Law (the "GCL")
provides that a Delaware corporation 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, 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 such person is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, 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 such person in connection with such action, suit or proceeding if he
or she 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, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.

        Section 145(b) of the GCL provides that a Delaware corporation 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 by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by such person in
connection with the defense or settlement of such action or suit if he or she
acted under similar standards, except that no indemnification may 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
court in which such action or suit was brought shall determine that despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to be indemnified for such expenses
which the court shall deem proper.

        Section 145 of the GCL further provides that to the extent a present or
former director or officer of a corporation has been successful in the defense
of any action, suit or proceeding referred to in subsection (a) and (b) or in
the defense of any claim, issue or matter therein, such person shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection therewith; that indemnification provided
for by Section 145 shall not be deemed exclusive of any other rights to which
the indemnified party may be entitled; and that the corporation may purchase and
maintain insurance on behalf of a director or officer of the corporation against
any liability asserted against such officer or director and incurred by him or
her in any such capacity or arising out of his or her status as such, whether or
not the corporation would have the power to indemnify him or her against such
liabilities under Section 145.

        As permitted by Section 102(b)(7) of the GCL, the Company's Certificate
of Incorporation provides that a director shall not be liable to the Company or
its stockholders for monetary damages for breach of fiduciary duty as a
director. However, such provision does not eliminate or limit the liability of a
director for acts or omissions not in good faith or for breaching his or her
duty of loyalty, engaging in intentional misconduct or knowingly violating a
law, paying a dividend or approving a stock repurchase which was illegal, or
obtaining an improper personal benefit.

        The Company's Certificate of Incorporation also requires that directors
and officers be indemnified to the maximum extent permitted by Delaware law. The
Company has entered into indemnity agreements with each of its directors and
executive officers. These indemnity agreements require that the Company pay on
behalf of each director and officer party thereto any amount that he or she is
or becomes legally obligated to pay because of any claim or claims made against
him or her because of any act or omission or neglect or breach of duty,
including any actual or alleged error or misstatement or misleading statement,
which he or she commits or suffers while acting in his or her capacity as a
director and/or officer of the Company and solely because of his or her being a
director 

                                       3

and/or officer. Under the GCL, absent such an indemnity agreement,
indemnification of a director or officer is discretionary rather than mandatory
(except in the case of a proceeding in which a director or officer is successful
on the merits). Consistent with the Company's Bylaw provision on the subject,
the indemnity agreements require the Company to make prompt payment of defense
and investigation costs and expenses at the request of the director or officer
in advance of indemnification, provided that the recipient undertakes to repay
the amounts if it is ultimately determined that he or she is not entitled to
indemnification for such expenses and provided further that such advance shall
not be made if it is determined that the director or officer acted in bad faith
or deliberately breached his or her duty to the Company or its stockholders and,
as a result, it is more likely than not that it will ultimately be determined
that he or she is not entitled to indemnification under the terms of the
indemnity agreement. The indemnity agreements make the advance of litigation
expenses mandatory absent a special determination to the contrary, whereas under
the GCL absent such an indemnity agreement, such advance would be discretionary.
Under the indemnity agreement, the director or officer is permitted to petition
the court to seek recovery of amounts due under the indemnity agreement and to
recover the expenses of seeking such recovery if he or she is successful.
Without the indemnity agreement, the Company would not be required to pay or
reimburse the director or officer for his or her expenses in seeking
indemnification recovery against the Company. By the terms of the indemnity
agreement, its benefits are not available if the director or officer has other
indemnification or insurance coverage for the subject claim or, with respect to
the matters giving rise to the claim, (i) received a personal benefit, (ii)
violated section 16(b) of the Securities Exchange Act of 1934 or analogous
provisions of law, or (iii) committed certain acts of dishonesty. Absent the
indemnity agreement, indemnification that might be made available to directors
and officers could be changed by amendments to the Company's Certificate of
Incorporation or Bylaws.

        The Company has a policy of directors and officers liability insurance
that insures the Company and its directors and officers against damages,
settlements, and defense costs under certain circumstances.
