     (c)  the prepayment of any Subordinated Note in violation of the provisions
          of Section 7 of this Note; or

     (d)  any event or condition shall occur which results in the acceleration
          of the maturity of any Debt or enables or, with the giving of notice
          or lapse of time or both, would enable the holder of such Debt or any
          Person acting on such holder's behalf to accelerate the maturity

          intended to be exclusive of any other right or remedy, and every right
          and remedy shall, to the extent permitted by law, be cumulative and in
          addition to every other right and remedy given hereunder or now or
          hereafter existing at law or in equity or otherwise. The assertion or
          employment of any right or remedy hereunder, or otherwise, shall not
          prevent the concurrent assertion or employment of any other
          appropriate right or remedy.

     (b)  No delay or omission of the Holder to exercise any right or power
          accruing upon any Default or Event of Default occurring and continuing
          as aforesaid shall impair any such right or power or shall be
          construed to be a waiver of any such Default or Event of Default or an
          acquiescence therein; and every power and remedy given by this Note or
          by law may be exercised from time to time, and as often as shall be
          deemed expedient, by the Holder.

6.   WAIVER OF PAST DEFAULTS.

     (a)  The Noteholder may waive any past Default or Event of Default

          Issuer and the Noteholder shall be restored to their former positions
          and rights hereunder, respectively; but no such waiver shall extend to
          any subsequent or other Default or impair any right consequent
          thereon.

     (b)  Upon any such waiver, such Default shall cease to exist and be deemed
          to have been cured and not to have occurred, and any Default or Event
          of Default arising therefrom shall be deemed to have been cured, and
          not to have occurred for every purpose of the Notes; but no such
          waiver shall extend to any subsequent or other default or Event of
          Default or impair any right consequent thereon.

          note issued contemporaneously herewith pursuant to the Transaction

          be redeemed or purchased directly or indirectly by the Issuer (or any
          of its subsidiaries), if at the time of such payment or purchase or
          immediately after giving effect thereto, (i) there shall exist a
          default in any payment with respect to the Senior Indebtedness or (ii)
          there shall have occurred an event of default as those terms may be
          defined in the instrument under which the same is outstanding (other
          than a default in the payment of amounts due thereon) with respect to
          the Senior Indebtedness, permitting the holders thereof to accelerate
          the maturity thereof, and such event of default shall not have been
          cured or waived or shall not have ceased to exist.

     (b)  Subject to payment in full of the Senior Indebtedness, the holders of
          the Subordinated Notes shall be subrogated to the rights of the
          holders of Senior Indebtedness to receive payments or distributions of
          the assets of the Issuer made on such Senior Indebtedness until all
          principal and interest on the Subordinated Notes shall be paid in
          full; and for purposes of such subrogation, no payments or
          distributions to the holders of Senior Indebtedness of any cash,
          property or securities to which any holders of the Subordinated Notes
          would be entitled except for the subordination provisions of this
          Section 6 shall, as between the holders of the Subordinated Notes and
          the Issuer and/or its creditors other than the holders of the Senior
          Indebtedness, be deemed to be a payment on account of the Senior
          Indebtedness.

     (c)  The provisions of this Section 7 are and are intended solely for the
          purposes of defining the relative rights of the holders of the
          Subordinated Notes and the holders of Senior Indebtedness and nothing
          in this Section 7 shall impair, as between the Issuer and any holders
          of the Subordinated Notes, the obligation of the Issuer, which is
          unconditional and absolute, to pay to the holders of the Subordinated
          Notes the principal thereof and interest thereon, in accordance with
          the terms of the Subordinated Notes, nor shall anything herein prevent
          any holders of the Subordinated Notes from exercising all remedies
          otherwise permitted by applicable law or hereunder upon default,
          subject to the rights set forth above of holders of Senior
          Indebtedness to receive cash, property or securities otherwise payable
          or deliverable to the holders of the Subordinated Notes.

     (d)  Upon any payment (including by redemption) which is not a payment in
          full of all of the principal amount and accrued interest of all
          outstanding Subordinated Notes, the aggregate amount of the payments
          shall be allocated to all the Subordinated Notes then outstanding in
          proportion to the amounts of principal and interest due thereunder, so
          that the amount of principal and interest paid under this Note shall
          bear the same ratio to the aggregate principal and accrued interest
          paid under all of the Subordinated Notes as the then outstanding

                                                                     Page 5 of 6

          principal and accrued interest then owed under this Note bears to the
          aggregate principal and accrued interest then owed under all
          Subordinated Notes then outstanding.

     consent of the Noteholder and the Issuer, provided, however, that no
     modification of Section 2 shall be made that would adversely affect the

               interest and the outstanding principal of this Note have not been
               paid on or before the Maturity date, the Issuer may request an
               extension of the Maturity Date until sufficient Net Cash Flow
               and/or Net Cash Proceeds are available to do so, but Noteholder
               shall have no obligation to grant such an extension.

          (d)  Compounding of Interest. Accrued but unpaid interest will be
               added to the principal balance hereof annually.

          (e)  No Impairment of Payment Obligation. No provision of this Note
               shall alter or impair the obligations of the Issuer to pay the

               and in the currency, herein prescribed.

          (f)  Prepayment. The principal hereunder shall be subject to
               prepayment by the Issuer at any time without the consent of the
               Noteholder and without premium or penalty, subject to any
               restriction on prepayment required by Comerica.

          (g)  Certain Note Transfers. If any of this Note, the Manning Note,
               the Davies First Note or the Hemsley Note (individually, a
               "Transferred Note") are sold, assigned or transferred (which
               sale, assignment or transfer shall be in full compliance with
               applicable securities laws) and new notes are issued to reflect
               such sale, assignment or transfer (individually, a "New Note" and
               collectively, "New Notes"), the amount of Net Cash Flow and Net
               Cash Proceeds that would have been applied to the Transferred
               Note under the terms of this Note shall be applied to the New
               Notes in proportion to the total amount of accrued interest or
               principal, as the case may be, owed under the New Notes at the
               time the computation is made."

2.   Subparagraph (a) of Paragraph 7 of the Note is amended and restated in its
     entirety to read as follows:

          herewith pursuant to the Transaction Agreement (each a "Subordinated
          Note and collectively, the "Subordinated Notes") shall be made, and no
          Subordinated Notes shall be redeemed or purchased directly or
          indirectly by the Issuer (or any of its subsidiaries), if at the time
          of such payment or purchase or immediately after giving effect
          thereto, (i) there shall exist a default in any payment with respect
          to the Senior Indebtedness or (ii) there shall have occurred an event
          of default as those terms may be defined in the instrument under which
          the same is outstanding (other than a default in the payment of
          amounts due thereon) with respect to the Senior Indebtedness,

                                                                     Page 3 of 4
<PAGE>

          permitting the holders thereof to accelerate the maturity thereof, and
          such event of default shall not have been cured or waived or shall not
          have ceased to exist."

3.   In all other respects, the Note shall remain as originally written.

IN WITNESS WHEREOF, the Issuer and the Noteholder have caused this Amendment to
