          distinct from those of any other Person;

     (b)  maintain its books, financial records and accounts (including
          inter-entity transaction accounts) in a manner so that it will not be

          functions with the assets, funds, liabilities or business functions of

          or more of its Affiliates (including transactions and agreements
          pursuant to which the assets or property of one is used or to be used
          by the other) to be entered into in the names of the Persons

          business with vendors or service providers or share overhead expenses,
          allocate fairly, appropriately non-arbitrarily the costs and expenses
          incurred in so doing between or among such Persons, with the result
          that each such Person bears its fair share of all such costs and
          expenses;

     (k)  to the extent that it contracts or does business with vendors or
          service providers where the goods or services are wholly or partially
          for the benefit of its Affiliates, allocate fairly, appropriately and
          non-arbitrarily the costs incurred in so doing to the Person for whose
          benefit the goods or services are provided, with the result that each
          such Person bears its fair share of all such costs;

     (l)  not enter into any guaranty, or otherwise become liable for, or pledge
          its assets to secure, the liabilities, debts or obligations of any
          other Person;

     (m)  hold itself out as separate and distinct from any other Person and
          shall not identify itself as a division or department of any other
          Person;

     (n)  ensure that decisions with respect to its business and daily
          operations shall be independently made (although the individual making
          any particular decision may also be an employee, officer or director
          of any one or more of its Affiliates) and shall not be dictated by its
          Affiliates;

     (o)  to the extent that it occupies any premises in the same location or

<PAGE>

          appropriately and non-arbitrarily any rent and overhead expenses among
          and between such Persons with the result that each bears its fair
          share of all such rent and expenses;

     (p)  cause its representatives and agents to hold themselves out to third
          parties as being its representatives or agents, as the case may be,
          and conduct its business using separate business cards, letterhead,
          purchase orders, invoices, checks and the like bearing its own name,
          it being understood that it need not have its own dedicated employees;

     (q)  to the extent that it share the same officers or other employees with
          its Affiliates, allocate fairly, appropriately and non-arbitrarily the
          salaries of and expenses related to providing other benefits to such
          officers and other employees between or among such Persons, with the

          and benefit costs associated with all such common or shared officers
          or other employees;

     (r)  maintain separate annual financial statements prepared in accordance

     (s)  pay or bear the cost of the preparation of its financial statements,
          and have such financial statements audited by an independent certified
          public accounting firm;

          financial statements of any other Person, cause to be included in such
          consolidated financial statements a narrative description of its
          separate assets, liabilities, business functions, operations and
          existence to ensure that such separate assets, liabilities, business
          functions, operations and existence are readily distinguishable by any
          Person receiving or relying upon a copy of such consolidated financial
          statements;

          date or dates, and at such times, and payable in preference to, or in
          such relation to, the dividends payable on any other class or classes

                     entitled to one vote for each share held.

                (b)  Subject to all of the rights of Preferred Stock or any
                     series thereof, the holders of Common Stock will be
                     entitled to receive, when, as and if declared by the Board
                     of Directors, out of funds legally available therefor,

                     to the rights of the holders of Preferred Stock, the
                     remaining net assets of the Corporation will be distributed
                     pro rata to the holders of Common Stock in accordance with
                     their respective rights and interests.

     Section 6. All shares of Common Stock or Preferred Stock of the
Corporation, including, without limitation, shares issued as a stock dividend,
shall, when the full lawful consideration fixed by the Board of Directors has
been paid, or when so issued as a stock dividend, be deemed fully paid and not
liable to any further call or assessment thereon, and the holders of such shares
shall not be liable for any further payment thereon. Any of the unissued shares
of capital stock of the Corporation may be issued from time to time in such
amount and manner, including, without limitation, in distribution as stock
dividends, and for such lawful consideration as the Board of Directors may
determine.
