ITEM 6.  INDEMNIFICATION  OF DIRECTORS AND OFFICERS.

     Section 145 of the General Corporation Law of the State of Delaware
("DGCL") provides that a corporation has the power to indemnify any director or
officer, or former director or officer, 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) against the expenses (including
attorneys' fees), judgments, fines or amounts paid in settlement actually and
reasonably incurred by them in connection with the defense of any action by
reason of being or having been directors or officers, if such


                                       2

<PAGE>

person shall have acted in good faith and in a manner reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, provided that such person had no reasonable
cause to believe his conduct was unlawful, except that, if such action shall be
in the right of the corporation, no such indemnification shall be provided as to
any claim, issue or matter as to which such person shall have been judged to
have been liable to the corporation unless and to the extent that the Court of
Chancery of the State of Delaware (the "Court of Chancery"), or any court in
which such suit or action was brought, shall determine 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 such court shall deem proper.

     Accordingly, the Restated Certificate of Incorporation of the Company
provides that the Company shall, to the maximum extent permitted under the DGCL,
indemnify each person who is or was a director or officer of the Company. The
Company may, by action of the Board of Directors, indemnify other employees and
agents of the Corporation, directors, officers, employees or agents of a
subsidiary, and each person serving as a director, officer, partner, member,
employee or agent of another corporation, partnership, limited liability
company, joint venture, trust or other enterprise, at the request of the
Company, with the same scope and effect as the indemnification of directors and
officers of the Company. However, the Company shall 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 Board of Directors or is a proceeding to enforce such person's
claim to indemnification pursuant to the rights granted by the Restated
Certificate of Incorporation or otherwise by the Company. The Company may also
enter into one or more agreements with any person which provide for
indemnification greater or different than that provided in the Restated
Certificate of Incorporation.

     Furthermore, a director of the Company shall not be 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 DGCL, or (4) for any transaction from which
the director derived an improper personal benefit.

     The Company's By-laws 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 manner in any
threatened, pending or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative ("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, while a director or officer of the
Company, a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise shall be indemnified and
held harmless by the Company to the fullest extent permitted by the DGCL. Such
indemnification shall continue as to a person who has ceased to be a director or
officer and shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that the Company shall 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 Board of Directors or is a Proceeding to enforce such person's
claim to indemnification pursuant to the rights granted by the Company's
By-laws. The Company shall pay the expenses incurred by any person described in
the first two sentences of this paragraph in defending any such Proceeding in
advance of its final disposition upon, to the extent such an undertaking is
required by applicable law, receipt of an undertaking by or on behalf of such
person to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the Company as authorized in the
Company's By-laws or otherwise.

     The Company's By-laws further provide that the indemnification and the
advancement of expenses incurred in defending a Proceeding prior to its final
disposition provided by, or granted pursuant to, the Company's By-laws shall not
be exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of the Restated Certificate of Incorporation, other
provision of the Company's By-laws or otherwise. The Company may also maintain
insurance, at its expense, to protect itself and any person who is or was a
director, officer, partner, member, employee or agent of the Company or a
subsidiary or of another corporation, partnership, limited liability company,
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.

     The Company's By-laws further provide that the Company may, to the extent
authorized from time to time by the Board of Directors, 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 person who
is or was an employee or


                                       3

<PAGE>

agent (other than a director or officer) of the Company or a subsidiary thereof
and to any person who is or was serving at the request of the Company or a
subsidiary thereof as a director, officer, partner, member, employee or agent of
another corporation, partnership, limited liability company, joint venture,
trust or other enterprise, including service with respect to employee benefit
plans maintained or sponsored by the Company or a subsidiary thereof, to the
fullest extent of the provisions of the Company's By-laws with respect to the
indemnification and advancement of expenses of directors and officers of the
Company.

     CCIC carries liability insurance for its directors and officers.

ITEM 9. UNDERTAKINGS.

(a)  We hereby undertake:

     (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.
               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 a prospectus filed
               with the Commission pursuant to Rule 424(b) 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;

          (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 Registration Statement is on Form S-3, Form S-8 or Form
         F-3 and 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 us 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)  We hereby undertake that, for purposes of determining any liability under
     the Securities Act of 1933, each filing of our 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 benefits plan's annual report
     pursuant to Section 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.

(h)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to our directors, officers and controlling persons
     pursuant to the foregoing provisions, or otherwise, we have been advised
     that in the opinion of the Securities and Exchange Commission such
     indemnification is against public policy as expressed in the Securities Act
     of 1933 and is, therefore, unenforceable. In the event that a claim for
     indemnification against such liabilities (other than the payment by us of
     expenses incurred or paid by a director, officer or controlling person 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, we will, unless in the opinion of our counsel
     the matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by us is
     against public policy as expressed in the Securities Act of 1933 and will
     be governed by the final adjudication of such issue.

ITEM 6.  INDEMNIFICATION  OF DIRECTORS AND OFFICERS.

     Section 145 of the General Corporation Law of the State of Delaware
("DGCL") provides that a corporation has the power to indemnify any director or
officer, or former director or officer, 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) against the expenses (including
attorneys' fees), judgments, fines or amounts paid in settlement actually and
reasonably incurred by them in connection with the defense of any action by
reason of being or having been directors or officers, if such

                                       2
person shall have acted in good faith and in a manner reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, provided that such person had no reasonable
cause to believe his conduct was unlawful, except that, if such action shall be
in the right of the corporation, no such indemnification shall be provided as to
any claim, issue or matter as to which such person shall have been judged to
have been liable to the corporation unless and to the extent that the Court of
Chancery of the State of Delaware (the "Court of Chancery"), or any court in
which such suit or action was brought, shall determine 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 such court shall deem proper.

     Accordingly, the Restated Certificate of Incorporation of the Company
provides that the Company shall, to the maximum extent permitted under the DGCL,
indemnify each person who is or was a director or officer of the Company. The
Company may, by action of the Board of Directors, indemnify other employees and
agents of the Corporation, directors, officers, employees or agents of a
subsidiary, and each person serving as a director, officer, partner, member,
employee or agent of another corporation, partnership, limited liability
company, joint venture, trust or other enterprise, at the request of the
Company, with the same scope and effect as the indemnification of directors and
officers of the Company. However, the Company shall 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 Board of Directors or is a proceeding to enforce such person's
claim to indemnification pursuant to the rights granted by the Restated
Certificate of Incorporation or otherwise by the Company. The Company may also
enter into one or more agreements with any person which provide for
indemnification greater or different than that provided in the Restated
Certificate of Incorporation.

     Furthermore, a director of the Company shall not be 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 DGCL, or (4) for any transaction from which
the director derived an improper personal benefit.

     The Company's By-laws 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 manner in any
threatened, pending or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative ("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, while a director or officer of the
Company, a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise shall be indemnified and
held harmless by the Company to the fullest extent permitted by the DGCL. Such
indemnification shall continue as to a person who has ceased to be a director or
officer and shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that the Company shall 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 Board of Directors or is a Proceeding to enforce such person's
claim to indemnification pursuant to the rights granted by the Company's
By-laws. The Company shall pay the expenses incurred by any person described in
the first two sentences of this paragraph in defending any such Proceeding in
advance of its final disposition upon, to the extent such an undertaking is
required by applicable law, receipt of an undertaking by or on behalf of such
person to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the Company as authorized in the
Company's By-laws or otherwise.

     The Company's By-laws further provide that the indemnification and the
advancement of expenses incurred in defending a Proceeding prior to its final
disposition provided by, or granted pursuant to, the Company's By-laws shall not
be exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of the Restated Certificate of Incorporation, other
provision of the Company's By-laws or otherwise. The Company may also maintain
insurance, at its expense, to protect itself and any person who is or was a
director, officer, partner, member, employee or agent of the Company or a
subsidiary or of another corporation, partnership, limited liability company,
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.

     The Company's By-laws further provide that the Company may, to the extent
authorized from time to time by the Board of Directors, 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 person who
is or was an employee or

                                       3
agent (other than a director or officer) of the Company or a subsidiary thereof
and to any person who is or was serving at the request of the Company or a
subsidiary thereof as a director, officer, partner, member, employee or agent of
another corporation, partnership, limited liability company, joint venture,
trust or other enterprise, including service with respect to employee benefit
plans maintained or sponsored by the Company or a subsidiary thereof, to the
fullest extent of the provisions of the Company's By-laws with respect to the
indemnification and advancement of expenses of directors and officers of the
Company.

     CCIC carries liability insurance for its directors and officers.

ITEM 9. UNDERTAKINGS.

(a)  We hereby undertake:

     (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.
               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 a prospectus filed
               with the Commission pursuant to Rule 424(b) 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;

          (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 Registration Statement is on Form S-3, Form S-8 or Form
         F-3 and 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 us 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)  We hereby undertake that, for purposes of determining any liability under
     the Securities Act of 1933, each filing of our 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 benefits plan's annual report
     pursuant to Section 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.

(h)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to our directors, officers and controlling persons
     pursuant to the foregoing provisions, or otherwise, we have been advised
     that in the opinion of the Securities and Exchange Commission such
     indemnification is against public policy as expressed in the Securities Act
     of 1933 and is, therefore, unenforceable. In the event that a claim for
     indemnification against such liabilities (other than the payment by us of
     expenses incurred or paid by a director, officer or controlling person 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, we will, unless in the opinion of our counsel
     the matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by us is
     against public policy as expressed in the Securities Act of 1933 and will
     be governed by the final adjudication of such issue.
