HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, NOTES, REPRESENTATIONS, AND
UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF
AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL NOTES OR DISCUSSIONS THE PARTIES HERETO. THERE ARE NO ORAL NOTES
AMONG THE BORROWER AND THE INVESTOR.

     Section 7.8.  Amendments, Etc.  No amendment or waiver of any provision of
this Note or any other Subordinated Note Document to which the Borrower is a
party, nor any consent to any departure by the Borrower or any Subsidiary

consented to by the Holders and the Borrower in writing, and each such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given.

     Section 7.9.  Maximum Interest Rate.  No provision of this Note or of any
other Subordinated Note Document shall require the payment or the collection of
interest in excess of the maximum amount permitted by applicable law. If any
excess of interest in such respect is hereby provided for, or shall be
adjudicated to be so provided, in any Subordinated Note Document or otherwise in
connection with the transactions contemplated hereby, the provisions of this
Section shall govern and prevail and neither the Borrower nor the sureties,
guarantors, successors, or assigns of the Borrower shall be obligated to pay the
excess amount of such interest or any other excess sum paid for the use,
forbearance, or detention of sums loaned pursuant hereto. In the event any
Holder ever receives, collects, or applies as interest any such sum, such amount
which would be in excess of the maximum amount permitted by applicable law shall
be applied as a payment and reduction of the principal of the indebtedness
evidenced by this Note; and, if the principal of this Note has been paid in
full, any remaining excess shall forthwith be paid to the Borrower. In
determining whether or not the interest paid or payable exceeds the maximum
rate, the Borrower and the Holders shall, to the extent permitted by applicable
law, (a) characterize any non-principal payment as an expense, fee, or premium
rather than as interest, (b) exclude voluntary prepayments and the effects
thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal
parts the total amount of
                                        7


interest throughout the entire contemplated term of the indebtedness evidenced
by this Note so that interest for the entire term does not exceed the maximum
rate.

     Section 7.10.  Notices.  All notices and other communications provided for
in this Note and the other Subordinated Note Documents to which the Borrower is
a party shall be given or made by telex, telegraph, telecopy, or in writing and

                                                                    SCHEDULE 4.1

                            SUBORDINATION PROVISIONS

     1.  Subordination.  Payment of principal and interest in respect of the
indebtedness evidenced by this Note shall be junior and subordinate and subject
in right of payment to all Senior Debt. Unless otherwise defined in this
Schedule, (a) all capitalized terms not otherwise defined have the meanings
given to them in the Notes and (b) all references to Sections are to Sections of
this Schedule 4.1.

     2.  Payments on Account of Subordinated Debt.

     (a) Except as set forth in this Section 2 or in Section 3 hereof, unless
and until all Senior Debt shall have been Paid In Full, the Company will not
make, and no holder of this Note will demand, accept, or receive, any direct or
indirect payment (in cash, property, by setoff, or otherwise) of or on account
of this Note and the holder of this Note shall not be entitled to declare this
Note to be in default, accelerate the payment date of this Note, file a petition
or claim under any Bankruptcy Law or take any other action with respect to the
Company or this Note as a consequence of the failure of the Company to make any
payment or perform any of its other obligations in respect of this Note.

     (b) Notwithstanding the provisions of Section 2(a), the holder of this Note
shall have the right to (i) accelerate pursuant to Section 6.2 of the Note the
payment of all amounts owed to the holder of this Note and (ii) commence any
action to enforce or collect such obligations and take any action otherwise
prohibited by Section 2(a); provided, however, that if and so long as an
Indenture Default or Indenture Event of Default exists or would exist after
giving effect to the payment of such amount the holder of this Note shall not be
entitled to receive and retain any amounts owed to it in respect of this Note
until all Senior Debt has been Paid In Full.

     3.  Insolvency, etc.  If an Event of Bankruptcy occurs, then and in any
such event:

          (a) all Senior Debt (including any interest thereon and any other
     obligation with respect to such Senior Debt accruing after the commencement
     of such proceedings and any additional interest that would have accrued
     thereon but for the commencement of such proceedings, whether or not such
     interest is a claim or is collectible) shall first be Paid In Full before
     any payment or distribution of any character, whether in cash, securities
     or other property, shall be made by the Company in respect of this Note;

          (b) any payment or distribution of any character, whether in cash,
     securities, or other property, which would otherwise (but for the terms
     hereof) be payable or deliverable by the Company in respect of this Note,
     shall be paid or delivered directly to the holders of Senior Debt at the
     time outstanding (or the Trustee), ratably according to the respective
     aggregate amounts remaining unpaid thereon, until all Senior Debt
     (including any interest thereon and any other obligation with respect to
     such Senior Debt accruing after the commencement of such proceedings and
     any additional interest that would have accrued thereon but for the
     commencement of such proceedings, whether or not such interest is a claim
     or is collectible) shall have been Paid In Full, and the holder of this
     Note at the time outstanding irrevocably authorizes, empowers and directs
     all receivers, trustees, liquidators, conservators and others having
     authority in the premises to effect all such payments and deliveries; and

          (c) the holder of this Note will at the request of the Trustee file
     any claim, proof of claim or other instrument of similar character
     necessary to enforce the obligations of the Company in respect of this
     Note. In the event that the holder of this Note shall fail to take such
     action requested by the Trustee, the Trustee may, as attorney-in-fact for
     the holder of this Note, take such action on behalf of the holder of this
     Note and the holder of this Note hereby appoints the Trustee as its
     attorney-in-fact to demand, sue for, collect and receive any and all such
     moneys, dividends or other assets and give acquittance therefor and to file
     any claim, proof of claim or other instrument of similar character and to
     take such other action (excluding acceptance or rejection of any plan of
     reorganization or

                                      4.1.1


     arrangement) in such Trustee's own name or in the name of the holder of
     this Note as such Trustee may deem necessary or advisable for the
     enforcement of the terms hereof and the holder of this Note will execute
     and deliver to each Trustee such other and further powers of attorney or
     other instruments as such Trustee may request in order to accomplish the
     foregoing. Notwithstanding the foregoing, the Holder, not the Trustee,
     shall be entitled to accept or reject any plan of reorganization or
     arrangement.

     4.  Payments and Distributions Received.  If any payment or distribution of
any character (whether in cash, securities or other property) or any security
shall be received by the holder of this Note in contravention of any of the
terms hereof and before all Senior Debt shall have been Paid In Full, such
payment or distribution or security shall be held in trust for the benefit of,
and shall be paid over or delivered and transferred to, the Trustee for the
benefit of the holders of the Senior Debt at the time outstanding for
application to the payment of all Senior Debt remaining unpaid, ratably
according to the respective aggregate amounts remaining unpaid thereon, to the
extent necessary for all such Senior Debt to be Paid In Full. In the event of
the failure of the holder of this Note to endorse or assign any such payment,
distribution or security, the Trustee is hereby irrevocably authorized to
endorse or assign the same.

     5.  Subrogation.  Upon the Payment In Full of all Senior Debt, the holder
of this Note shall be subrogated to any rights of the holders of Senior Debt to
receive all further payments or distributions applicable to the Senior Debt,
until this Note shall have been Paid In Full, and for purposes of such
subrogation, any payment or distribution applicable to Senior Debt of cash,
securities, or other property, to which the holder of this Note would have been
entitled except for these subordination provisions, shall not, as between the
Company and its creditors (other than the holders of the Senior Debt), on the
one hand, and the holder of this Note, on the other hand, be deemed to be a
payment or distribution by the Company to or on account of Senior Debt.

     6.  Obligations Not Impaired.  Except to the extent this Note provides that
(i) this Note may not become due and payable or be paid, and (ii) the holder of
this Note may not commence or join in any proceeding under any Bankruptcy Law
unless the holders of Senior Debt shall also join in bringing such proceeding,
nothing contained in this Note shall impair, as between the Company and the
holder of this Note, the obligation of the Company, which is absolute and
unconditional, to pay to the holder of this Note the principal hereof and
interest hereon as and when the same shall become due and payable in accordance
with the terms hereof.

     7.  Subordination Not Affected, etc.  The terms of this Note, the
subordination effected hereby and the rights of the holders of the Senior Debt,
shall not be affected by (i) any amendment of or addition or supplement to any
Senior Debt or any instrument or agreement relating thereto, (ii) any exercise
or nonexercise of any right, power or remedy under or in respect of any Senior
Debt or any instrument or agreement relating thereto, (iii) any sale, exchange,
release or other transaction affecting all or any part of any property at any
time pledged or mortgaged to secure, or however securing, Senior Debt, or (iv)
any waiver, consent, release, indulgence, extension, renewal, modification,
delay or other action, inaction or omission, in respect of any Senior Debt or
any instrument or agreement relating thereto, whether or not the holder of this
Note shall have had notice or knowledge of any of the foregoing.

     8.  Amendments, Waiver, etc.  Neither this Note nor any term hereof may be
amended, modified or waived, except with the prior written consent of the
holders owning a majority of the outstanding principal amount of the Senior
Debt; provided, however, that any consent delivered by the Trustee shall be
deemed to have been so authorized.

     9.  Subordination a Condition to Consent of Holders of Senior Debt.  The
Holder of this Note, by its acceptance hereof, agrees that the consent of the
holders of the Senior Debt to the incurrence by the Company of such indebtedness
has been given in reliance upon the subordination of such indebtedness to the
Senior Debt.
