ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Subsection (a) of Section 145 of the General Corporation Law of the State
of Delaware empowers a corporation to 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, 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 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.

     Subsection (b) of Section 145 empowers a corporation to 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,


                                      II-1
<PAGE>   3


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
may be made in respect of any claim, issue or matter as to which such person
shall have been made to be liable to the corporation unless and only to the
extent that the 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 Court of
Chancery or such other court shall deem proper.

     Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
in the 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; that indemnification provided for by Section 145
shall not be deemed exclusive of any other rights to which the indemnified party
may be entitled; that indemnification provided for by Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of such person's heirs, executors and administrators; and empowers the
corporation to purchase and maintain insurance on behalf of a director or
officer of the corporation against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such
whether or not the corporation would have the power to indemnify him against
such liabilities under Section 145.

     Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a certificate of incorporation may contain a provision eliminating
or limiting the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
provided that such provision shall not eliminate or limit the liability of a
director (i) for any breach of the director's duty of loyalty to the corporation
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, or (iv) for any transaction
from which the director derived an improper personal benefit.

     Article Seventh of the Company's Amended and Restated Certificate of
Incorporation states that:

     The Corporation shall, to the maximum extent permitted from time to time
under the General Corporation Law of the State of Delaware, indemnify and upon
request shall advance expenses to any person who is or was a party or is
threatened to be made a party to any threatened, pending or completed action,
suit, proceeding or claim, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was or has agreed to be a
director or officer of the Corporation, or while a director or officer 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, including service with respect to employee benefit plans, against
expenses (including attorneys' fees and expenses), judgments, fines, penalties
and amounts paid in settlement or incurred in connection with the investigation,
preparation to defend or defense of such action, suit, proceeding or claim,
whether civil, criminal, administrative or investigative, by reason of the fact
that he is or was or has agreed to be a director or officer of the Corporation,
or while a director or officer 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, including service with
respect to employee benefit plans, against expenses (including attorneys' fees
and expenses), judgments, fines, penalties and amounts paid in settlement or
incurred in connection with the investigation, preparation to defend or defense
of such action, suit, proceeding, claim or counterclaim initiated by or on
behalf of such person.

     Such indemnification shall not be exclusive of other indemnification rights
arising under any bylaw, agreement, vote of directors or stockholders or
otherwise and shall inure to the benefit of the heirs and legal representatives
of such person. Any repeal or modification of the foregoing provisions of this
Section 7(c) shall be prospective only, and shall not adversely affect any right
or protection of a director or officer of the Corporation existing at the time
of such repeal or modification. A director of the Corporation shall not be
personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Corporation 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 General
Corporation Law of the State of Delaware, or (iv) for any transaction from which
the director derived an improper personal benefit. If the General Corporation
Law of the State of Delaware is amended to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the General Corporation Law of the State of Delaware, as so
amended. Any repeal or modification


                                      II-2
<PAGE>   4


of this Section by the stockholders of the Corporation shall be prospective
only, and shall not adversely affect any limitation on the personal liability of
a director of the Corporation existing at the time of such repeal or
modification.

     In addition, Article IX of the Company's Bylaws further provides that the
Company shall indemnify its officers, directors and employees to the fullest
extent permitted by law.

     The Company enters into indemnification agreements with certain of its
executive officers and directors.

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;

               (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


                                      II-3
<PAGE>   5


               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 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, each filing of the
          registrant's annual report pursuant to Section 13(a) or 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 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 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 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Subsection (a) of Section 145 of the General Corporation Law of the State
of Delaware empowers a corporation to 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, 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 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.

     Subsection (b) of Section 145 empowers a corporation to 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,

                                      II-1
3

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
may be made in respect of any claim, issue or matter as to which such person
shall have been made to be liable to the corporation unless and only to the
extent that the 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 Court of
Chancery or such other court shall deem proper.

     Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
in the 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; that indemnification provided for by Section 145
shall not be deemed exclusive of any other rights to which the indemnified party
may be entitled; that indemnification provided for by Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of such person's heirs, executors and administrators; and empowers the
corporation to purchase and maintain insurance on behalf of a director or
officer of the corporation against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such
whether or not the corporation would have the power to indemnify him against
such liabilities under Section 145.

     Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a certificate of incorporation may contain a provision eliminating
or limiting the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
provided that such provision shall not eliminate or limit the liability of a
director (i) for any breach of the director's duty of loyalty to the corporation
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, or (iv) for any transaction
from which the director derived an improper personal benefit.

     Article Seventh of the Company's Amended and Restated Certificate of
Incorporation states that:

     The Corporation shall, to the maximum extent permitted from time to time
under the General Corporation Law of the State of Delaware, indemnify and upon
request shall advance expenses to any person who is or was a party or is
threatened to be made a party to any threatened, pending or completed action,
suit, proceeding or claim, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was or has agreed to be a
director or officer of the Corporation, or while a director or officer 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, including service with respect to employee benefit plans, against
expenses (including attorneys' fees and expenses), judgments, fines, penalties
and amounts paid in settlement or incurred in connection with the investigation,
preparation to defend or defense of such action, suit, proceeding or claim,
whether civil, criminal, administrative or investigative, by reason of the fact
that he is or was or has agreed to be a director or officer of the Corporation,
or while a director or officer 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, including service with
respect to employee benefit plans, against expenses (including attorneys' fees
and expenses), judgments, fines, penalties and amounts paid in settlement or
incurred in connection with the investigation, preparation to defend or defense
of such action, suit, proceeding, claim or counterclaim initiated by or on
behalf of such person.

     Such indemnification shall not be exclusive of other indemnification rights
arising under any bylaw, agreement, vote of directors or stockholders or
otherwise and shall inure to the benefit of the heirs and legal representatives
of such person. Any repeal or modification of the foregoing provisions of this
Section 7(c) shall be prospective only, and shall not adversely affect any right
or protection of a director or officer of the Corporation existing at the time
of such repeal or modification. A director of the Corporation shall not be
personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Corporation 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 General
Corporation Law of the State of Delaware, or (iv) for any transaction from which
the director derived an improper personal benefit. If the General Corporation
Law of the State of Delaware is amended to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the General Corporation Law of the State of Delaware, as so
amended. Any repeal or modification

                                      II-2
4

of this Section by the stockholders of the Corporation shall be prospective
only, and shall not adversely affect any limitation on the personal liability of
a director of the Corporation existing at the time of such repeal or
modification.

     In addition, Article IX of the Company's Bylaws further provides that the
Company shall indemnify its officers, directors and employees to the fullest
extent permitted by law.

     The Company enters into indemnification agreements with certain of its
executive officers and directors.

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;

               (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

                                      II-3

               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 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, each filing of the
          registrant's annual report pursuant to Section 13(a) or 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 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 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.
