          NOW THEREFORE, in consideration of the premises and the mutual

hereafter incurred and for which a Guarantor is obligated.

respective meanings set forth in the Notes.

     Section 2.  GUARANTEE.

     Each Guarantor unconditionally guarantees, jointly with the other
Guarantors and severally, as a primary obligor and not merely as a surety, (a)
the due and punctual payment of (i) the principal of and premium, if any, and
interest (including interest accruing during the pendency of any Proceeding
regardless of whether allowed or allowable in such Proceeding) on the Notes,
when and as due, whether at maturity, by acceleration, upon one or more dates
set for prepayment or otherwise and (ii) all other obligations, including
indemnities and fees, costs and expenses, whether primary, secondary, direct,
contingent, fixed or otherwise (including obligations incurred during the
pendency of any Proceeding, regardless of whether allowed or allowable in such
Proceeding), of the Issuers under the Notes and (b) the due and punctual
performance of all covenants, agreements, obligations and liabilities of the
Issuers under or pursuant to the Notes (all the monetary and other obligations
in this Section 2 collectively referred to as the "GUARANTEED OBLIGATIONS").
Each Guarantor further agrees that the Guaranteed Obligations may be extended or
renewed in accordance with the terms of the Notes, in whole or in part, without
notice to or further assent from it, and that it will remain bound upon its
guarantee notwithstanding any extension or renewal of any Guaranteed Obligation.

     Section 3.  GUARANTEED OBLIGATIONS NOT WAIVED; NO DISCHARGE OR DIMINISHMENT
                 OF GUARANTEE.

     To the fullest extent permitted by applicable law, each Guarantor waives
presentment to, demand of payment from and protest to the Issuers of any of the
Guaranteed Obligations, and also waives notice of acceptance of its guarantee
and notice of protest for nonpayment. To the fullest extent permitted by
applicable Law, the obligations of each Guarantor hereunder shall not be subject
to any reduction, limitation, impairment or termination for any reason (other
than the indefeasible payment in full in cash of the Guaranteed Obligations),
and shall not be subject to any defense or setoff, counterclaim, recoupment or
termination whatsoever by reason of the invalidity, illegality or
unenforceability of the Guaranteed Obligations or otherwise. Without limiting
the generality of the foregoing, the obligations of each Guarantor hereunder
shall not be discharged or impaired or otherwise affected by (a) the failure of
any holder of Notes to assert any claim or demand or to enforce or exercise any
right or remedy against the Issuers, or any other Guarantor under the provisions
of the Purchase Agreement, any other Principal Document (as defined in the
Purchase Agreement) or any other agreement; (b) any default, failure or delay,
willful or otherwise, in the performance of the Guaranteed Obligations; or (c)
any other act or omission that may or might in any manner or to any extent vary
the risk of any Guarantor or that would otherwise operate as a discharge of each
Guarantor as a matter of law or equity (other than the indefeasible payment in
full in cash of all the Guaranteed Obligations).

     Section 4.  GUARANTEE OF PAYMENT.

     Each Guarantor further agrees that its guarantee constitutes a guarantee of
payment when due and not of collection, and waives any right to require that any
resort be had by the holders of Notes to any security held for payment of the
Guaranteed Obligations or to any balance of any deposit account or credit on the
books of any holder of Notes in favor of the Issuers or any other Person.

                                       -2-

     Section 5.  DEFENSES OF THE ISSUERS WAIVED.

     To the fullest extent permitted by applicable law, each Guarantor waives
any defense based on or arising out of any defense of the Issuers or the
unenforceability of the Guaranteed Obligations or any part thereof from any
cause, or the cessation from any cause of the liability of the Issuers, other
than the final and indefeasible payment in full in cash of the Guaranteed
Obligations. The holders of the Notes may, at their election, compromise or
adjust any part of the Guaranteed Obligations, make any other accommodation with
the Issuers or any other guarantor or exercise any other right or remedy
available to them against the Issuers or any other guarantor, without affecting
or impairing in any way the liability of any Guarantor hereunder except to the
extent the Guaranteed Obligations have been fully and indefeasibly paid in cash.
To the fullest extent permitted by applicable law, each Guarantor waives any
defense arising out of any such election even though such election operates,
pursuant to applicable law, to impair or to extinguish any right of
reimbursement or subrogation or other right or remedy of such Guarantor against
the Issuers or any guarantor, as the case may be, or any security.

     Section 6.  AGREEMENT TO PAY; SUBROGATION.

     In furtherance of the foregoing and not in limitation of any other right
that the holders of Notes have at law or in equity against any Guarantor by
virtue hereof, upon the failure of the Issuers to pay any Guaranteed Obligation
when and as the same shall become due, whether at maturity, by acceleration,
after notice of prepayment or otherwise, each Guarantor hereby promises to and
will forthwith pay, or cause to be paid, to such Person as the holders of Notes
shall designate in cash the amount of such unpaid Guaranteed Obligations. Upon
payment by any Guarantor of any sums to the holders of Notes as provided above,
all rights of such Guarantor against the Issuers arising as a result thereof by
way of right of subrogation, contribution, reimbursement, indemnity or otherwise
shall in all respects be subordinate and junior in right of payment to the prior
indefeasible payment in full in cash of all the Guaranteed Obligations. If any
amount shall erroneously be paid to any Guarantor on account of such
subrogation, contribution, reimbursement, indemnity or similar right, such
amount shall be held in trust for the benefit of the holders of Notes and shall
forthwith be turned over to such Person as the holders of Notes shall designate
in the exact form received by such Guarantor (duly endorsed by such Guarantor to
such designated Person, if required) to be credited against the payment of the
Guaranteed Obligations, whether matured or unmatured, in accordance with the
terms of the Notes, the Purchase Agreement and the Principal Documents.

     Section 7.  INFORMATION.

     Each Guarantor assumes all responsibility for being, and keeping itself,
informed of the Issuers' financial condition and assets, and of all other
circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations
and the nature, scope and extent of the risks that such Guarantor assumes and
incurs hereunder, and agrees that none of the holders of Notes will have any
duty to advise any of the Guarantors of information known to it or any of them
regarding such circumstances or risks.

     Section 8.  SUBORDINATION.

     The Guarantors hereby agree that the indebtedness and obligations hereunder
shall be fully subordinated to Guarantor Senior Indebtedness to the same extent
that the indebtedness and obligations of the Issuers under the Notes are
subordinated to Senior Indebtedness (as defined in the Notes) pursuant to
Section 2 of the Notes. The holders of Senior Indebtedness shall be deemed to be
third party beneficiaries of this Section 8, the terms of which shall not be
modified without the prior written consent of the Senior Agent or the holders
holding fifty-one percent (51%) of the principal amount of the Notes at the time
then outstanding.

     Section 9.  TERMINATION.

     This Guarantee (a) shall terminate when all the Guaranteed Obligations have
been indefeasibly paid in full and (b) shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any Guaranteed Obligation is rescinded or must otherwise be restored by any
holders of Notes or any Issuer or Guarantor upon the bankruptcy or
reorganization of any Issuer or Guarantor.

     Section 10. ASSIGNMENTS.

     Whenever in this Guarantee any of the parties hereto is referred to, such
reference shall be deemed to include the successors and permitted assigns of
such party; and all covenants, promises and agreements by or on behalf of the
Guarantors or the holders of Notes that are contained in this Guarantee shall
bind and inure to the benefit of each party hereto and their respective
successors and permitted assigns, except that no Guarantor shall have the right
to assign its rights or obligations hereunder without the prior written consent
of the holders holding fifty-one percent (51%) of the principal amount of the
Notes at the time then outstanding.

     Section 11. WAIVERS; AMENDMENT.

     No failure or delay of the holders of Notes in exercising any power or
right in this Guarantee shall operate as a waiver hereof or thereof, nor shall
any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such right or power, preclude any other or
further exercise of any other right or power. No waiver of any provision of this
Guarantee or consent to any departure by the Guarantors therefrom shall in any
event be effective unless the same shall be authorized by the holders holding
fifty-one percent (51%) of the principal amount of the Notes at the time then
outstanding, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice or demand on
the Guarantors in any case shall entitle the Guarantors to any other or further
notice or demand in similar or other circumstances.

     Section 12. GOVERNING LAW; JURISDICTION AND VENUE.

          (a)  ALL QUESTIONS CONCERNING THE CONSTRUCTION, INTERPRETATION AND
VALIDITY OF THIS GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE DOMESTIC LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY CHOICE
OR CONFLICT OF LAW

                                       -4-
<Page>

PROVISION OR RULE (WHETHER OF THE STATE OF NEW YORK OR ANY OTHER JURISDICTION)
THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE
STATE OF NEW YORK.

          (b)  THE GUARANTORS AGREE THAT JURISDICTION AND VENUE IN ANY ACTION
BROUGHT BY ANY PARTY HERETO PURSUANT TO THIS GUARANTEE SHALL EXCLUSIVELY LIE IN
ANY FEDERAL OR STATE COURT LOCATED IN THE COUNTY OF NEW YORK IN THE STATE OF NEW
YORK. BY EXECUTION AND DELIVERY OF THIS GUARANTEE, THE GUARANTORS IRREVOCABLY
SUBMIT TO THE JURISDICTION OF SUCH COURTS FOR THEMSELVES AND IN RESPECT OF THEIR
PROPERTY WITH RESPECT TO SUCH ACTION. THE GUARANTORS IRREVOCABLY AGREE THAT
VENUE WOULD BE PROPER IN SUCH COURT, AND HEREBY WAIVE ANY OBJECTION THAT SUCH
COURT IS AN IMPROPER OR INCONVENIENT FORUM FOR THE RESOLUTION OF SUCH ACTION.
THE GUARANTORS HEREBY AGREE THAT SERVICE UPON THEM BY REGISTERED OR CERTIFIED
MAIL (RETURN RECEIPT REQUESTED) SHALL CONSTITUTE SUFFICIENT NOTICE. NOTHING
HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY
LAW OR SHALL LIMIT THE RIGHT OF THE HOLDERS OF NOTES TO BRING PROCEEDINGS
AGAINST ANY GUARANTOR IN THE COURTS OF ANY OTHER JURISDICTION.

     Section 13. WAIVER OF JURY TRIAL.

     THE GUARANTORS HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION (a) ARISING UNDER THIS GUARANTEE OR (b) IN ANY
WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES
HERETO OR ANY OF THEM IN RESPECT TO THIS GUARANTEE, IN EACH CASE WHETHER NOW
EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE. EACH GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY
AND THAT ANY PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS GUARANTEE
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE
WAIVER OF THEIR RIGHTS TO TRIAL BY JURY.

     Section 14. NOTICES.

     All communications and notices hereunder shall be in writing and given as
provided in Section 12.2 of the Purchase Agreement. Each Guarantor acknowledges
and agrees that all communications and notices hereunder to such Guarantor shall
be given to it in care of the Company, at the address specified for the Company
in the Purchase Agreement.

     Section 15. SURVIVAL OF AGREEMENT.

          (a)      All agreements and covenants contained herein or made in
writing by or on behalf of a Guarantor in connection with the transactions
contemplated hereby shall survive the execution and delivery of this Guarantee
without limit. No termination or cancellation (regardless of

                                       -5-
<Page>

cause or procedure) of this Guarantee in any way affects or impairs the powers,
obligations, duties, rights and liabilities of the parties hereto in any way
with respect to any transaction or event occurring prior to such termination or
cancellation, or any of the representations contained in this Guarantee, the
Notes, the Purchase Agreement and the Principal Documents and all such
undertakings, agreements, covenants, warranties and representations shall
survive such termination or cancellation as provided above.

          (b)       Each Guarantor further agrees that to the extent such
Guarantor makes a payment or payments under this Guarantee, which payment or
payments or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
receiver or any other party under any bankruptcy, insolvency or similar state or
United States federal Law, then, to the extent of such payment or repayment, the
obligation or part thereof intended to be satisfied shall be revived and
continued in full force and effect as if such payment had not been received by
the holders of Notes.

     Section 16. SEVERABILITY.

     Whenever possible, each provision of this Guarantee will be interpreted in
such manner as to be effective and valid under applicable law, but if any
provision of this Guarantee is held to be invalid, illegal or unenforceable in
any respect under any applicable law in any jurisdiction, such invalidity,
illegality or unenforceability will not affect any other provision or any other
jurisdiction, and such invalid, void or otherwise unenforceable provisions shall
be null and void. It is the intent of the parties, however, that any invalid,
void or otherwise unenforceable provisions be automatically replaced by other
provisions which are as similar as possible in terms to such invalid, void or
otherwise unenforceable provisions but are valid and enforceable to the fullest
extent permitted by applicable Law.

     Section 17. HEADINGS.

     Section headings used herein are for convenience of reference only and are
not to affect the construction of, or to be taken into consideration in
interpreting, this Guarantee.
