                              SUBSIDIARY GUARANTEE

     Subject to Section 10.06 of the Indenture, the undersigned Guarantor hereby
unconditionally guarantees to each Holder of a Note authenticated and delivered
by the Trustee and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of the, Indenture, the Notes and the
Obligations of the Company under the Notes or under the Indenture, that: (a) the
principal of, premium, if any, interest and Liquidated Damages, if any, on the
Notes will be promptly paid in full when due, subject to any applicable grace
period, whether at maturity, by acceleration, redemption or otherwise, and
interest on overdue principal, premium, if any, (to the extent permitted by law)
interest on any interest, if any, and Liquidated Damages, if any, on the Notes
and all other payment Obligations of the Company to the Holders or the Trustee
under the Indenture or under the Notes will be promptly paid in full and
performed, all in accordance with the terms thereof; and (b) in case of any
extension of time of payment or renewal of any Notes or any of such other
payment Obligations, the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, subject to
any applicable grace period, whether at stated maturity, by acceleration,
redemption or otherwise. Failing payment when so due of any amount so guaranteed
or any performance so guaranteed for whatever reason, the Guarantor will be
obligated to pay the same immediately. An Event of Default under the Indenture
or the Notes shall constitute an event of default under this Subsidiary
Guarantee, and shall entitle the Holders to accelerate the Obligations of the
Guarantor hereunder in the same manner and to the same extent as the Obligations
of the Company. The Guarantor hereby agrees that its Obligations hereunder shall
be unconditional, irrespective of the validity, regularity or enforceability of
the Notes or the Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder with respect to any provisions hereof or
thereof, the recovery of any judgment against the Company, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of the Guarantor. The Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that this Subsidiary Guarantee will not be discharged except by
complete performance of the Obligations contained in the Notes and the
Indenture. If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantor, or any Note Custodian, Trustee, liquidator
or other similar official acting in relation to either the Company or the
Guarantor, any amount paid by the Company or the Guarantor to the Trustee or
such Holder, this Subsidiary Guarantee, to the extent theretofore discharged,
shall be reinstated in full force and effect. The Guarantor agrees that it shall
not be entitled to, and hereby waives, any right of subrogation in relation to
the Holders in respect of any Obligations guaranteed hereby. The Guarantor
further agrees that, as between the Guarantor, on the one hand, and the Holders
and the Trustee, on the other hand, (a) the maturity of the Obligations
guaranteed hereby may be accelerated as provided in Article 6 of the Indenture
for the purposes of this Subsidiary Guarantee, notwithstanding any stay,
injunction or other
<PAGE>
prohibition preventing such acceleration in respect of the Obligations
guaranteed thereby, and (b) in the event of any declaration of acceleration of
such Obligations as provided in Article 6 of the Indenture, such Obligations
(whether or not due and payable) shall forthwith become due and payable by the
Guarantor for the purpose of this Subsidiary Guarantee. The Guarantor shall have
the right to seek contribution from any non-paying Guarantor so long as the
exercise of such right does not impair the rights of the Holders under the
Subsidiary Guarantees.

     The obligations of the Guarantor to the Holders and to the Trustee pursuant
to this Subsidiary Guarantee and the Indenture are expressly set forth in
Article 10 of the Indenture, and reference is hereby made to such Indenture for
the precise terms of this Subsidiary Guarantee. The terms of Article 10 of the
Indenture are incorporated herein by reference. This Subsidiary Guarantee is
subject to release as and to the extent provided in Sections 10.04 and 10.05 of
the Indenture.

     This is a continuing Guarantee and shall remain in full force and effect
and shall be binding upon the Guarantor and its respective successors and
assigns to the extent set forth in the Indenture until full and final payment of
all of the Company's Obligations under the Notes and the Indenture and shall
inure to the benefit of the successors and assigns of the Trustee and the
Holders and, in the event of any transfer or assignment of rights by any Holder
or the Trustee, the rights and privileges herein conferred upon that party shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions hereof. This is a Subsidiary Guarantee of
payment and not a guarantee of collection.

     This Subsidiary Guarantee shall not be valid or obligatory for any purpose
until the certificate of authentication on the Note upon which this Subsidiary
Guarantee is noted shall have been executed by the Trustee or an authenticating
agent under the Indenture by the manual signature of one of its authorized
officers.

     For purposes hereof, the Guarantor's liability shall be limited to the
lesser of (i) the aggregate amount of the Obligations of the Company under the
Notes and the Indenture and (ii) the amount, if any, which would not have (A)
rendered the Guarantor "insolvent" (as such term is defined in the Bankruptcy
Law and in the Debtor and Creditor Law of the State of New York) or (B) left the
Guarantor with unreasonably small capital at the time its Subsidiary Guarantee
of the Notes was entered into; provided that, it will be a presumption in any
lawsuit or other proceeding in which the Guarantor is a party that the amount
guaranteed pursuant to the Subsidiary Guarantee is the amount set forth in
clause (i) above unless any creditor, or representative of creditors of the
Guarantor, or debtor in possession or trustee in bankruptcy of the Guarantor,
otherwise proves in such a lawsuit that the aggregate liability of the Guarantor
is limited to the amount set forth in clause (ii) above. The Indenture provides
that, in making any determination as to the solvency or sufficiency of capital
of the Guarantor in accordance with the previous sentence, the right of the
Guarantor to contribution from other Guarantors and any other rights such
Guarantors may have, contractual or otherwise, shall be taken into account.

                              SUBSIDIARY GUARANTEE

     Subject to Section 10.06 of the Indenture, the undersigned Guarantor hereby
unconditionally guarantees to each Holder of a Note authenticated and delivered
by the Trustee and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of the, Indenture, the Notes and the
Obligations of the Company under the Notes or under the Indenture, that: (a) the
principal of, premium, if any, interest and Liquidated Damages, if any, on the
Notes will be promptly paid in full when due, subject to any applicable grace
period, whether at maturity, by acceleration, redemption or otherwise, and
interest on overdue principal, premium, if any, (to the extent permitted by law)
interest on any interest, if any, and Liquidated Damages, if any, on the Notes
and all other payment Obligations of the Company to the Holders or the Trustee
under the Indenture or under the Notes will be promptly paid in full and
performed, all in accordance with the terms thereof; and (b) in case of any
extension of time of payment or renewal of any Notes or any of such other
payment Obligations, the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, subject to
any applicable grace period, whether at stated maturity, by acceleration,
redemption or otherwise. Failing payment when so due of any amount so guaranteed
or any performance so guaranteed for whatever reason, the Guarantor will be
obligated to pay the same immediately. An Event of Default under the Indenture
or the Notes shall constitute an event of default under this Subsidiary
Guarantee, and shall entitle the Holders to accelerate the Obligations of the
Guarantor hereunder in the same manner and to the same extent as the Obligations
of the Company. The Guarantor hereby agrees that its Obligations hereunder shall
be unconditional, irrespective of the validity, regularity or enforceability of
the Notes or the Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder with respect to any provisions hereof or
thereof, the recovery of any judgment against the Company, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of the Guarantor. The Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that this Subsidiary Guarantee will not be discharged except by
complete performance of the Obligations contained in the Notes and the
Indenture. If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantor, or any Note Custodian, Trustee, liquidator
or other similar official acting in relation to either the Company or the
Guarantor, any amount paid by the Company or the Guarantor to the Trustee or
such Holder, this Subsidiary Guarantee, to the extent theretofore discharged,
shall be reinstated in full force and effect. The Guarantor agrees that it shall
not be entitled to, and hereby waives, any right of subrogation in relation to
the Holders in respect of any Obligations guaranteed hereby. The Guarantor
further agrees that, as between the Guarantor, on the one hand, and the Holders
and the Trustee, on the other hand, (a) the maturity of the Obligations
guaranteed hereby may be accelerated as provided in Article 6 of the Indenture
for the purposes of this Subsidiary Guarantee, notwithstanding any stay,
injunction or other
<PAGE>
prohibition preventing such acceleration in respect of the Obligations
guaranteed thereby, and (b) in the event of any declaration of acceleration of
such Obligations as provided in Article 6 of the Indenture, such Obligations
(whether or not due and payable) shall forthwith become due and payable by the
Guarantor for the purpose of this Subsidiary Guarantee. The Guarantor shall have
the right to seek contribution from any non-paying Guarantor so long as the
exercise of such right does not impair the rights of the Holders under the
Subsidiary Guarantees.

     The obligations of the Guarantor to the Holders and to the Trustee pursuant
to this Subsidiary Guarantee and the Indenture are expressly set forth in
Article 10 of the Indenture, and reference is hereby made to such Indenture for
the precise terms of this Subsidiary Guarantee. The terms of Article 10 of the
Indenture are incorporated herein by reference. This Subsidiary Guarantee is
subject to release as and to the extent provided in Sections 10.04 and 10.05 of
the Indenture.

     This is a continuing Guarantee and shall remain in full force and effect
and shall be binding upon the Guarantor and its respective successors and
assigns to the extent set forth in the Indenture until full and final payment of
all of the Company's Obligations under the Notes and the Indenture and shall
inure to the benefit of the successors and assigns of the Trustee and the
Holders and, in the event of any transfer or assignment of rights by any Holder
or the Trustee, the rights and privileges herein conferred upon that party shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions hereof. This is a Subsidiary Guarantee of
payment and not a guarantee of collection.

     This Subsidiary Guarantee shall not be valid or obligatory for any purpose
until the certificate of authentication on the Note upon which this Subsidiary
Guarantee is noted shall have been executed by the Trustee or an authenticating
agent under the Indenture by the manual signature of one of its authorized
officers.

     For purposes hereof, the Guarantor's liability shall be limited to the
lesser of (i) the aggregate amount of the Obligations of the Company under the
Notes and the Indenture and (ii) the amount, if any, which would not have (A)
rendered the Guarantor "insolvent" (as such term is defined in the Bankruptcy
Law and in the Debtor and Creditor Law of the State of New York) or (B) left the
Guarantor with unreasonably small capital at the time its Subsidiary Guarantee
of the Notes was entered into; provided that, it will be a presumption in any
lawsuit or other proceeding in which the Guarantor is a party that the amount
guaranteed pursuant to the Subsidiary Guarantee is the amount set forth in
clause (i) above unless any creditor, or representative of creditors of the
Guarantor, or debtor in possession or trustee in bankruptcy of the Guarantor,
otherwise proves in such a lawsuit that the aggregate liability of the Guarantor
is limited to the amount set forth in clause (ii) above. The Indenture provides
that, in making any determination as to the solvency or sufficiency of capital
of the Guarantor in accordance with the previous sentence, the right of the
Guarantor to contribution from other Guarantors and any other rights such
Guarantors may have, contractual or otherwise, shall be taken into account.
