provisions of the Indenture, the Notes, the Warrant Agreement and the Warrants
and that the Notes and Warrants represented by each Unit Certificate shall be

                 SECTION  8.  Unit Agent.  The Unit Agent undertakes the duties
and obligations imposed by this Agreement upon the following terms and
conditions, by which the Company and the holders of Units, by their acceptance

                 (a)      The statements contained herein and in the Unit
         Certificates shall be taken as statements of the Company, and the Unit
         Agent assumes no responsibility for the correctness of any of the
         same, other than with respect to the certificate of authentication,
         except such as describe the Unit Agent or action taken or to be taken
         by it.  The Unit Agent assumes no responsibility with respect to the
         distribution of the Unit Certificates except as herein otherwise
         specifically provided.

                 (b)      The Unit Agent shall not be responsible for any
         failure of the Company to comply with any of the covenants in this
         Agreement, Unit Certificates, the Indenture or the Warrant Agreement
         to be complied with by the Company.

                 (c)      The Unit Agent may consult at any time with counsel
         satisfactory to it (who may be counsel for the Company) and the Unit
         Agent shall incur no liability or responsibility to the Company or to
         any holder of any Unit Certificate in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in accordance
         with the written opinion or the written advice of such counsel.

                 (d)      The Unit Agent shall incur no liability or
         responsibility to the Company or to any holder of any Unit Certificate
         for any action taken in reliance on any Unit Certificate, certificate
         of shares, notice, resolution, waiver, consent, order, certificate, or
         other paper, document or instrument reasonably believed by the Unit
         Agent

                                                                               8

         to be genuine and to have been signed, sent or presented by the proper
         party or parties.

                 (e)      The Company agrees to pay to the Unit Agent
         reasonable compensation for all services rendered by the Unit Agent in
         connection with this Agreement, to reimburse the Unit Agent for all
         expenses, taxes and governmental charges and other charges of any kind
         and nature incurred by the Unit Agent in connection with this
         Agreement and to indemnify the Unit Agent and save it harmless against
         any  and all losses and liabilities, including judgments, costs and
         counsel fees and actual expenses, for any action taken or omitted by
         the Unit Agent or arising in connection with this Agreement and the
         exercise by the Unit Agent of its rights hereunder and the performance
         by the Unit Agent of any of its obligations hereunder except as a
         result of the Unit Agent's gross negligence or bad faith or willful
         misconduct.

                 (f)      The Unit Agent, and any stockholder, director,
         officer, affiliate or employee ("Related Parties") of it, may buy,
         sell or deal in any of the Units, Notes, Warrants, Class B Common
         Stock or other securities of the Company or become pecuniarily
         interested in any transaction in which the Company may be interested,
         or contract with or lend money to the Company or otherwise act as
         fully and freely as though it were not Unit Agent under this
         Agreement.  Nothing herein shall preclude the Unit Agent or such
         Related Parties from acting in any other capacity for the Company or
         for any other legal entity.

                 (g)      The Unit Agent shall act hereunder solely as agent
         for the Company, the Trustee and the Warrant Agent, and its duties
         shall be determined solely by the provisions hereof.  The Unit Agent
         shall not be liable for anything which it may do or refrain from doing
         in connection with this Agreement except for its own gross negligence
         or bad faith or willful misconduct.

                 (h)      No provision of this Agreement shall require the Unit
         Agent to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder or in the
         exercise of any of its rights or powers if it shall have reasonable
         grounds for believing that repayment of such funds or adequate
         indemnity against such risk or liability is not reasonably assured to
         it.

                 (i)      The Unit Agent shall be under no obligation to
         institute any action, suit or legal proceeding or to take any other
         action unless the Company or one or more registered holders of Unit
         Certificates shall furnish the Unit Agent with security and indemnity
         for any costs and expenses which may be incurred acceptable to the
         Unit Agent.  This provision shall not affect the power of the Unit
         Agent to
   3
                                                                               9

         take such action as it may consider proper, whether with or without
         any such security or indemnity.

         All rights of action under this Agreement or under any of the Units
         may be enforced by the Unit Agent without the possession of any of the
         Unit Certificates or the production thereof at any trial or other
         proceeding relative thereto, and any such action, suit or proceeding
         instituted by the Unit Agent shall be brought in its name as Unit
         Agent and any recovery of judgment shall be for the ratable benefit of
         the registered holders of the Units, as their respective rights or
         interests may appear.

                 (j)      Before the Unit Agent acts or refrains from acting
         with respect to any matter contemplated by this Unit Agreement, it may
         require:

                          (1)     an Officers' Certificate stating that, in the
                 opinion of the signers, all conditions precedent, if any,
                 provided for in this Unit Agreement relating to the proposed
                 action have been complied with; and

                          (2)     an opinion of counsel for the Company stating
                 that, in the opinion of such counsel, all such conditions
                 precedent have been complied with.

                 Each Officers' Certificate or opinion of counsel with respect
to compliance with a condition or covenant provided for in this Unit Agreement
shall include:

                          (1)     a statement that the person making such
                 certificate or opinion has read such covenant or condition;

                          (2)     a brief statement as to the nature and scope
                 of the examination or investigation upon which the statements
                 or opinions contained in such certificate or opinion are based;

                          (3)     a statement that, in the opinion of such
                 person, he or she has made such examination or investigation
                 as is necessary to enable him or her to express an informed
                 opinion as to whether or not such covenant or condition has
                 been complied with; and

                          (4)     a statement as to whether or not, in the
                 opinion of such person, such condition or covenant has been
                 complied with.

                 The Unit Agent shall not be liable for any action it takes or
omits to take in good faith in reliance on any such certificate or opinion.

                                                                              10

                 (k)      In the absence of bad faith on its part, the Unit
         Agent may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Unit Agent and conforming to the
         requirements of this Unit Agreement.  However, the Unit Agent shall
         examine the certificates and opinions to determine whether or not they
         conform to the requirements of this Unit Agreement.

                 (l)      The Unit Agent may rely and shall be fully protected
         in relying upon any document believed by it to be genuine and to have
         been signed or presented by the proper person.  The Unit Agent need
         not investigate any fact or matter stated in the document.

                 (m)      The Unit Agent may act through agents and shall not
         be responsible for the misconduct or negligence of any agent appointed
         with due care.

                                  SECTION  9.  Resignation and Appointment of
Successor.  (a)  The Company agrees, for the benefit of the holders from time
to time of the Unit Certificates, that there shall at all times be a Unit Agent
hereunder.

                 (b)      The Unit Agent may at any time resign as Unit Agent
by giving written notice to the Company of such intention on its part,
specifying the date on which its desired resignation shall become effective,
provided that such date shall be at least 90 days after the date on which such
notice is given unless the Company agrees to accept less notice.  Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor Unit Agent, qualified as provided in Section 9(d) hereof, by written
instrument in duplicate signed on behalf of the Company, one copy of which
shall be delivered to the resigning Unit Agent and one copy to the successor
Unit Agent.  As provided in Section 9(d) hereof, such resignation shall become
effective upon the earlier of (x) the acceptance of the appointment by the
successor Unit Agent or (y) 90 days after receipt by the Company of notice of
such resignation.  The Company may, at any time and for any reason, and shall,
upon any event set forth in the next succeeding sentence, remove the Unit Agent
and appoint a successor Unit Agent by written instrument in duplicate,
specifying such removal and the date on which it is intended to become
effective, signed on behalf of the Company, one copy of which shall be
delivered to the Unit Agent being removed and one copy to the successor Unit
Agent.  The Unit Agent shall be removed as aforesaid if it shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Unit Agent or of its property shall be appointed, or any public
officer shall take charge or control of it or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation.  Any removal of the
Unit Agent and any appointment of a successor Unit Agent shall become effective
upon acceptance of appointment by the successor Unit Agent as provided in 
Section
   5
                                                                              11

9(d).  As soon as practicable after appointment of the successor Unit Agent,
the Company shall cause written notice of the change in the Unit Agent to be
given to each of the registered holders of the Units in the manner provided for
in Section 10 hereof.

                 (c)  Upon resignation or removal of the Unit Agent, if the
Company shall fail to appoint a successor Unit Agent within a period of 90 days
after receipt of such notice of resignation or removal, then the holder of any
Unit Certificate or the Unit Agent may apply to a court of competent
jurisdiction for the appointment of a successor to the Unit Agent.  Pending
appointment of a successor to the Unit Agent, either by the Company or by such
a court, the duties of the Unit Agent shall be carried out by the Company.

                 (d)  Any successor Unit Agent, whether appointed by the
Company or by a court, shall be a bank or trust company in good standing,
incorporated under the laws of the United States of America or any State
thereof and having, at the time of its appointment, a combined capital surplus
of at least $50 million.  Such successor Unit Agent shall execute and deliver
to its predecessor and to the Company an instrument accepting such appointment
hereunder and all the provisions of this Agreement, and thereupon such
successor Unit Agent, without any further act, deed or conveyance, shall become
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as Unit Agent hereunder, and
such predecessor shall thereupon become obligated to (i) transfer and deliver,
and such successor Unit Agent shall be entitled to receive, all securities,
records or other property on deposit with or held by such predecessor as Unit
Agent hereunder and (ii) upon payment of the amounts then due it pursuant to
Section 8(e) hereof, pay over, and such successor Unit Agent shall be entitled
to receive, all monies deposited with or held by any predecessor Unit Agent
hereunder.

                 (e)      Any corporation or bank into which the Unit Agent
hereunder may be merged or converted, or any corporation or bank with which the
Unit Agent may be consolidated, or any corporation or bank resulting from any
merger, conversion or consolidation to which the Unit Agent shall be a party,
or any corporation or bank to which the Unit Agent shall sell or otherwise
transfer all or substantially all of its corporate trust business, shall be the
successor to the Unit Agent under this Agreement (provided that such
corporation or bank shall be qualified as aforesaid) without the execution or
filing of any document or any further act on the part of any of the parties
hereto.

                 (f)      No Unit Agent under this Unit Agreement shall be
personally liable for any action or omission of any successor Unit Agent.

                 SECTION  10.  Notices to the Company and Unit Agent, Trustee
