Parent Company hereby irrevocably, unconditionally and jointly and severally
guarantees to each Noteholder the due and punctual payment in full of (i) the
principal of, Make-Whole Amount, if any, and interest on (including interest
accruing after the filing of any petition in bankruptcy, or the commencement of
any insolvency, reorganization or like proceeding, relating to the Issuer,
whether or not a claim for post-filing or post-petition interest is allowed in
such proceeding), and any other amounts due under, the Notes when and as the
same shall become due and payable (whether at stated maturity or by required or
optional prepayment or by acceleration or otherwise) and (ii) any other sums
which may become due under the terms and provisions of the Amended and Restated
Note Purchase Agreements or the Notes (all such obligations described in clauses
(i) and (ii) above are herein called the "Guaranteed Obligations"). The guaranty
in the preceding sentence is an absolute, present and continuing guaranty of
payment and not of collectibility and is in no way conditional or contingent
upon any attempt to collect from the Issuer or any other guarantor of the Notes
or upon any other action, occurrence or circumstance whatsoever. In the event
that the Issuer shall fail so to pay any of the Guaranteed Obligations, the
Parent Company agrees to pay the same when due to the Noteholders entitled
thereto, without demand, presentment, protest or notice of any kind, in lawful
money of the United States of America, at the place for payment specified in the
Notes and the Amended and Restated Note Purchase Agreements. Each default in
payment of principal of, Make-Whole Amount, if any, or interest on any Note
shall give rise to a separate cause of action hereunder and separate suits may
be brought hereunder as each cause of action arises. The Parent Company hereby
agrees that the Notes issued in connection with the Amended and Restated Note
Purchase Agreements may make reference to this Guaranty.

     The Parent Company hereby agrees to pay and to indemnify and save each
Noteholder harmless from and against any damage, loss, cost or expense
(including attorneys' fees) which such Noteholder may incur or be subject to as
a consequence, direct or indirect, of (i) any breach


                                       -4-



by the Parent Company or the Issuer of any warranty, covenant, term or condition
in, or the occurrence of any default under, this Guaranty, the Notes or the
Amended and Restated Note Purchase Agreements, together with all expenses
resulting from the compromise or defense of any claims or liabilities arising as
a result of any such breach or default, and (ii) any legal action commenced to
challenge the validity or enforceability of this Guaranty, the Notes or the
Amended and Restated Note Purchase Agreements.

     Section 2.2. Obligations Absolute. The obligations of the Parent Company
hereunder shall be primary, absolute, irrevocable and unconditional,
irrespective of the validity, regularity or enforceability of the Notes or of
the Amended and Restated Note Purchase Agreements, shall not be subject to any
counterclaim, setoff, deduction or defense based upon any claim the Parent
Company may have against the Issuer or any Noteholder or otherwise, and shall
remain in full force and effect without regard to, and shall not be released,
discharged or in any way affected by, any circumstance or condition whatsoever
(whether or not the Parent Company shall have any knowledge or notice thereof),
including, without limitation: (a) any amendment, modification of or supplement
to the Amended and Restated Note Purchase Agreements or the Notes (except that
the obligations of the Parent Company hereunder shall apply to the Amended and
Restated Note Purchase Agreements or the Notes as so amended, modified or
supplemented) or any assignment or transfer of any thereof or of any interest
therein, or any furnishing, acceptance or release of any security for the Notes;
(b) any waiver, consent, extension, indulgence or other action or inaction under
or in respect of the Notes or in respect of the Amended and Restated Note
Purchase Agreements; (c) any bankruptcy, insolvency, readjustment, composition,
liquidation or similar proceeding with respect to the Issuer or its property;
(d) any merger, amalgamation or consolidation of any of the Parent Company or
any of its Subsidiaries with any other Subsidiary or with any other entity or
any sale, lease or transfer of any or all of the assets of the Parent Company or
any of its Subsidiaries to any Person; (e) any failure on the part of the Issuer
for any reason to comply with or perform any of the terms of any other agreement
with the Parent Company; or (f) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor. The Parent
Company covenants that its obligations hereunder will not be discharged except
by payment in full of all of the Guaranteed Obligations.

     Section 2.3. Waiver. The Parent Company unconditionally waives to the
fullest extent permitted by law, (a) notice of acceptance hereof, of any action
taken or omitted in reliance hereon and of any defaults by the Issuer in the
payment of any amounts due under the Notes or the Amended and Restated Note
Purchase Agreements, and of any of the matters referred to in Section 2.2
hereof; (b) all notices which may be required by statute, rule of law or
otherwise to preserve any of the rights of each Noteholder against the Parent
Company, including, without limitation, presentment to or demand for payment
from the Issuer or the Parent Company with respect to any Note, notice to the
Issuer or the Parent Company of default or protest for nonpayment or dishonor
and the filing of claims with a court in the event of the bankruptcy of the
Issuer; (c) any right to the enforcement, assertion or exercise by any
Noteholder of any right, power or remedy conferred in this Guaranty, the Amended
and Restated Note Purchase Agreements or the Notes; (d) any requirement or
diligence on the part of any Noteholder; and (e) any other act or omission or
thing or delay to do any other act or thing which might in any


                                       -5-



manner or to any extent vary the risk of the Parent Company or which might
otherwise operate as a discharge of the Parent Company.

     Section 2.4. Obligations Unimpaired. The Parent Company authorizes the
Noteholders, without notice or demand to the Parent Company and without
affecting its obligations hereunder, from time to time (a) to renew, compromise,
extend, accelerate or otherwise change the time for payment of, or otherwise
change the terms of, all or any part of the Notes or the Amended and Restated
Note Purchase Agreements or any other instrument referred to therein; (b) to
take and hold security for the payment of the Notes, for the performance of this
Guaranty or otherwise for the Debt guaranteed hereby and to exchange, enforce,
waive and release any such security; (c) to apply any such security and to
direct the order or manner of sale thereof as the Noteholders in their sole
discretion may determine; (d) to obtain additional or substitute endorsers or
guarantors; (e) to exercise or refrain from exercising any rights against the
Parent Company and others; and (f) to apply any sums, by whomsoever paid or
however realized, to the payment of the principal of, Make-Whole Amount, if any,
and interest on the Notes and any other Guaranteed Obligations. The Parent
Company waives any right to require the Noteholders to proceed against any
additional or substitute endorsers or guarantors or to pursue or exhaust any
security provided by the Issuer, the Parent Company or any other person or to
pursue any other remedy available to such Noteholders.

     Section 2.5. Subrogation; Subordination. (a) Subject to the final sentence
of Section 2.5(c) hereof, the Parent Company will not (i) exercise any rights
which it may have acquired by way of subrogation under this Guaranty, by any
payment made hereunder or otherwise, or (ii) accept any payment on account of
such subrogation rights, or any rights of reimbursement, indemnity or any rights
or recourse to any security for the Notes or this Guaranty unless and until all
of the obligations, undertakings or conditions to be performed or observed by
the Issuer pursuant to the Notes and the Amended and Restated Note Purchase
Agreements at the time of the Parent Company's exercise of any such right shall
have been performed, observed or paid in full.

     (b) For a period of one hundred eighty (180) days after the payment in full
of the Guaranteed Obligations, the Parent Company will not, subject to the final
sentence of Section 2.5(c) hereof, exercise (x) any rights of subrogation which
it may at any time otherwise have as a result of this Guaranty (whether
statutory or otherwise) to the claims of the Noteholders against the Issuer or
any other guarantor of the Guaranteed Obligations (each referred to herein as
the "Other Party") and all contractual, statutory or common law rights of
reimbursement, contribution or indemnity from any Other Party which it may at
any time otherwise have as a result of this Guaranty; (y) any right to enforce
any other remedy which the Noteholders now have or may hereafter have against
any Other Party, any endorser or any other guarantor of all or any part of the
Guaranteed Obligations; and (z) any claims (as such term is defined in the
Bankruptcy Code) it may at any time otherwise have against any Other Party
arising from any transaction whatsoever, including without limitation its right
to assert or enforce any such claims.

     (c) The Parent Company hereby subordinates the payment of all Debt and
other obligations of the Issuer or any Other Party owing to the Parent Company,
whether now existing


                                       -6-



or hereafter arising, including, without limitation, all rights and claims
described in Sections 2.5(a) and (b) hereof, to the indefeasible payment in full
of all Guaranteed Obligations. If the Required Holders so request, any such Debt
or other obligations shall be enforced and performance received by the Parent
Company as trustee for the Noteholders and the proceeds thereof shall be paid
over to the Noteholders to be credited and applied upon the Guaranteed
Obligations, whether matured or unmatured, as may be directed by Required
Holders, but without reducing or affecting in any manner the liability of the
Parent Company under this Guaranty.

     (d) If any amount or other payment is made to or accepted by the Parent
Company in violation of the preceding Sections 2.5(a), (b) or (c), such amount
shall be deemed to have been paid to the Parent Company for the benefit of, and
held in trust for the benefit of, the Noteholders and shall be paid over to the
Noteholders, in the form received (together with any necessary endorsements),
promptly upon request therefor, to be applied to the Guaranteed Obligations,
whether matured or unmatured, in such order as may be directed by the Required
Holders. The Parent Company acknowledges that it will receive benefits from the
exchange of the Existing Notes for the Notes and the reorganization of the
Parent Company and its Subsidiaries contemplated by the Amended and Restated
Note Purchase Agreements and that the waiver set forth in this paragraph is
knowingly made in contemplation of such benefits.

     Section 2.6. Reinstatement of Guaranty. This Guaranty shall continue to be
effective, or be reinstated, as the case may be, if and to the extent at any
time payment, in whole or in part, of any of the sums due to any Noteholder for
principal, Make-Whole Amount, if any, or interest on the Notes or any of the
other Guaranteed Obligations is rescinded or must otherwise be restored or
returned by such Noteholder upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of the Issuer, or upon or as a result of the
appointment of a custodian, receiver, trustee or other officer with similar
powers with respect to the Issuer or any substantial part of its property, or
otherwise, all as though such payments had not been made. If an event permitting
the acceleration of the maturity of the principal amount of the Notes shall at
any time have occurred and be continuing and such acceleration shall at such
time be prevented or the right of any Noteholder to receive any payment under
any Note shall at such time be delayed or otherwise affected by reason of the
pendency against the Issuer of a case or proceeding under a bankruptcy or
insolvency law, for purposes of this Guaranty and the Parent Company's
obligations hereunder, the maturity of such principal amount shall be deemed to
have been accelerated with the same effect as if the Noteholders had accelerated
the same in accordance with the terms of the Amended and Restated Note Purchase
Agreements, and the Parent Company shall forthwith pay such accelerated
principal amount, accrued interest and Make-Whole Amount, if any, thereon and
any other amounts guaranteed hereunder.

SECTION 3. AFFIRMATIVE COVENANTS.

     The Parent Company covenants that so long as any of the Notes are
outstanding:

     Section 3.1. Financial and Business Information. The Parent Company shall

     its Subsidiaries or relating to the ability of the Parent Company to
     perform its obligations hereunder or the Issuer to perform its obligations
     under the Amended and Restated Note Purchase Agreements or the Notes as
     from time to time may be reasonably requested by any Noteholder.

The Parent Company authorizes its independent chartered accountants to discuss
the affairs, finances and accounts of the Parent Company and its Subsidiaries
with the representatives of the Noteholders as provided in Section 7.3(b) of the
Amended and Restated Note Purchase Agreements.

     Section 3.2. Compliance with Law. The Parent Company will, and will cause
each of its Subsidiaries to, comply with all laws, ordinances or governmental
rules or regulations to which each of them is subject, including, without
limitation, Environmental Laws, and will obtain and maintain in effect all
licenses, certificates, permits, franchises and other governmental
authorizations necessary to the ownership of their respective properties or to
the conduct of their respective businesses, in each case to the extent necessary
to ensure that non-compliance with such laws, ordinances or governmental rules
or regulations or failures to obtain or maintain in effect such licenses,
certificates, permits, franchises and other governmental authorizations could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. Without limitation of the foregoing, the Parent Company will,
and will cause each of its Subsidiaries to, not be a Person described in Section
1 of the Anti-Terrorism Order, and not engage in any dealings or transactions,
or otherwise be associated, with any such Person.

     Section 3.3. Insurance. The Parent Company will, and will cause each of its
Subsidiaries to, maintain, with insurers reasonably determined by the Parent
Company in good faith to be financially sound and reputable, insurance with
respect to their respective properties and businesses against such casualties
and contingencies, of such types, on such terms and in such amounts (including
deductibles, co-insurance and self-insurance, if adequate reserves are
maintained with respect thereto) as is customary in the case of entities of
established reputations engaged in the same or a similar business and similarly
situated.

     Section 3.4. Maintenance of Properties. The Parent Company will, and will
cause each of its Subsidiaries to, maintain and keep, or cause to be maintained
and kept, their respective properties in good repair, working order and
condition (other than ordinary wear and tear), so that the business carried on
in connection therewith may be properly conducted at all times,


                                      -10-



provided that this Section shall not prevent the Parent Company or any
Subsidiary from discontinuing the operation and the maintenance of any of its
properties if such discontinuance is desirable in the conduct of its business
and the Parent Company has concluded that such discontinuance could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

     Section 3.5. Payment of Taxes and Claims. The Parent Company will, and will
cause each of its Subsidiaries to, file all tax returns required to be filed in
any jurisdiction and to pay and discharge all taxes shown to be due and payable
on such returns and all other taxes, assessments, governmental charges, or
levies imposed on them or any of their properties, assets, income or franchises,
to the extent such taxes and assessments have become due and payable and before
they have become delinquent and all claims for which sums have become due and
payable that have or might become a Lien on properties or assets of the Parent
Company or any Subsidiary, provided that neither the Parent Company nor any
Subsidiary need pay any such tax, assessment, charge, levy or claim if (a) the
amount, applicability or validity thereof is contested by the Parent Company or
such Subsidiary on a timely basis in good faith and in appropriate proceedings,
and the Parent Company or a Subsidiary has established adequate reserves
therefor in accordance with GAAP on the books of the Parent Company or such
Subsidiary or (b) the nonpayment of all such taxes and assessments in the
aggregate could not reasonably be expected to have a Material Adverse Effect.

     Section 3.6. Corporate Existence, Etc. The Parent Company will at all times
preserve and keep in full force and effect its corporate existence. Subject to
Sections 10.4, 10.5 and 10.7 of the Amended and Restated Note Purchase
Agreements, the Parent Company will at all times preserve and keep in full force
and effect the legal existence of each of its Subsidiaries (unless merged,
consolidated or amalgamated into or with the Parent Company or another
Subsidiary) and all rights and franchises of the Parent Company and its
Subsidiaries unless, in the good faith judgment of the Parent Company, the
termination of or failure to preserve and keep in full force and effect such
legal existence, right or franchise could not, individually or in the aggregate,
have a Material Adverse Effect.

     Section 3.7. Notes to Rank Pari Passu. The obligations of the Parent
Company under this Guaranty are and at all times shall rank at least pari passu
in right of payment with all other present and future unsecured Senior Debt
(actual or contingent) of the Parent Company.

SECTION 4. NEGATIVE COVENANTS.

     The Parent Company covenants that so long as any of the Notes are
outstanding:

     Section 4.1. Nature of Business. The Parent Company will not, and will not
permit any of its Subsidiaries to, engage in any business if, as a result, the
general nature of the business in which the Parent Company and its Subsidiaries,
taken as a whole, would then be engaged would be substantially changed from the
general nature of the business in which the Parent Company and its Subsidiaries,
taken as a whole, are engaged on the Effective Date.


                                      -11-



     Section 4.2. Transactions with Affiliates. The Parent Company will not, and
will not permit any Subsidiary to, enter into directly or indirectly any
Material transaction or Material group of related transactions (including,
without limitation, the purchase, lease, sale or exchange of properties of any
kind or the rendering of any service) with any Affiliate (other than the Parent
Company or another Subsidiary), except in the ordinary course and pursuant to
the reasonable requirements of the Parent Company's or such Subsidiary's
business and upon fair and reasonable terms no less favorable to the Parent
Company or such Subsidiary than would be obtainable in a comparable arm's-length
transaction with a Person not an Affiliate.

     Section 4.3. Most Favored Lender Status. The Parent Company will not, and
will not permit any Subsidiary to, enter into, assume or otherwise become bound
or obligated under any agreement evidencing, securing, guaranteeing or otherwise
relating to Designated Debt that contains, or amend any such agreement to
contain, one or more Additional Covenants or Additional Defaults, unless the
Parent Company or such Subsidiary has offered to make an amendment to this
Guaranty and the Amended and Restated Note Purchase Agreements, in form and
substance satisfactory to the Required Holders, to add to or amend this Guaranty
and the Amended and Restated Note Purchase Agreements to contain such Additional
Covenants or Additional Defaults; provided, however, in the event that the
Parent Company or any Subsidiary enters into, assumes or otherwise becomes bound
or obligated under, or so amends, any such agreement without making such offer,
or if such offer was made and has not been rejected by the Required Holders,
this Guaranty and the Amended and Restated Note Purchase Agreements shall,
without any further action on the part of the Parent Company, the Issuer or any
of the Noteholders, be deemed to be amended automatically to include each
Additional Covenant and each Additional Default contained in such agreement. The
Parent Company further covenants to, and to cause each of its Subsidiaries to,
promptly execute and deliver at its expense (including the reasonable fees and
expenses of counsel for the Noteholders) an amendment to this Guaranty and the
Amended and Restated Note Purchase Agreements in form and substance satisfactory
to the Required Holders evidencing the amendments of this Guaranty and the
Amended and Restated Note Purchase Agreements to include such Additional
Covenants and Additional Defaults, provided that the execution and delivery of
such amendments shall not be a precondition to the effectiveness of such
amendment as provided for in this Section 4.3, but shall merely be for the
convenience of the parties hereto.

     Section 4.4. Purchase of Notes. The Parent Company will not, and will not
permit any Subsidiary to, purchase, redeem, prepay or otherwise acquire,
directly or indirectly, any of the outstanding Notes except pursuant to an offer
to purchase made by the Parent Company or a Subsidiary pro rata to the
Noteholders of all Notes at the time outstanding upon the same terms and
conditions. Any such offer shall provide each Noteholder with sufficient
information to enable it to make an informed decision with respect to such
offer, and shall remain open for at least 10 Business Days. If the Noteholders
of more than 25% of the principal amount of the Notes then outstanding accept
such offer, the Parent Company shall, or shall cause such Subsidiary to,
promptly notify the remaining Noteholders of such fact and the expiration date
for the acceptance by Noteholders of Notes of such offer shall be extended by
the number of days necessary to give each such remaining Noteholder at least 10
Business Days from its receipt of such notice to accept such offer.


                                      -12-



     Section 4.5. Defaults under Amended and Restated Note Purchase Agreements.
The Parent Company will not, and will not permit any Subsidiary to, take or fail
to take any action if the taking or failing to take such action would cause a
Default or an Event of Default to occur or continue to exist under the Amended
and Restated Note Purchase Agreements. Without limiting the generality of the
foregoing, the Parent Company will, and will cause each of its Subsidiaries to,
take, or refrain from taking, any action, as from time to time requested by the
Issuer, in order to enable the Issuer to cause the Parent Company and its
Subsidiaries to comply with the provisions of Sections 7, 9, 10 and 11 of the
Amended and Restated Note Purchase Agreements.

SECTION 5. REPRESENTATIONS AND WARRANTIES OF THE PARENT COMPANY.

     The Parent Company represents and warrants to each Noteholder that:

     Section 5.1. Organization; Power and Authority. The Parent Company is a
corporation duly incorporated and validly existing under the laws of Canada, and
is duly qualified as a foreign corporation and is in good standing in each
jurisdiction in which such qualification is required by law, other than those
jurisdictions as to which the failure to be so qualified or in good standing
could not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. The Parent Company has the corporate power and
authority to own or hold under lease the properties it purports to own or hold
under lease, to transact the business it transacts and proposes to transact, to
execute and deliver this Guaranty and to perform the provisions hereof.

     Section 5.2. Authorization, Etc. This Guaranty has been duly authorized by
all necessary corporate action on the part of the Parent Company, and this
Guaranty constitutes, a legal, valid and binding obligation of the Parent
Company enforceable against the Parent Company in accordance with its terms,
except as such enforceability may be limited by (a) applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement of creditors' rights generally and (b) general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

     Section 5.3. Disclosure. Except as disclosed in Schedule 5.3, this
Guaranty, the documents, certificates or other writings delivered to the
Noteholders by or on behalf of the Parent Company or the Issuer in connection
with the transactions contemplated by the Amended and Restated Note Purchase
Agreements and the financial statements listed in Schedule 5.5, taken as a
whole, do not contain any untrue statement of a material fact or omit to state
any material fact necessary to make the statements therein not misleading in
light of the circumstances under which they were made. Except as expressly
described in Schedule 5.3, or in one of the documents, certificates or other
writings identified therein, or in the financial statements listed in Schedule
5.5, since December 31, 2004, there has been no change in the financial
condition, operations, business, properties or prospects of the Parent Company
or any Subsidiary except changes that, individually or in the aggregate, could
not reasonably be expected to have a Material Adverse Effect. There is no fact
known to the Parent Company that could reasonably be expected to have a Material
Adverse Effect that has not been set forth herein or in the other documents,
certificates and other writings delivered to each Noteholder by or on


                                      -13-

outstanding owned by the Parent Company and each other Subsidiary and, as of the
Effective Date, whether such Subsidiary is a Material Subsidiary, (2) of the
Parent Company's Affiliates, other than Subsidiaries, and (3) of the Parent
Company's directors and senior officers.

     (b) All of the outstanding share capital or similar equity interests of
each Subsidiary shown in Schedule 5.4 as being owned by the Parent Company and
its Subsidiaries have been validly issued, are fully paid and nonassessable and
are owned by the Parent Company or another Subsidiary free and clear of any Lien
(except as otherwise disclosed in Schedule 5.4).

     (c) Each Subsidiary identified in Schedule 5.4 is a corporation or other
legal entity duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization, and is duly qualified as a foreign
corporation or other legal entity and is in good standing in each jurisdiction
in which such qualification is required by law, other than those jurisdictions
as to which the failure to be so qualified or in good standing could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. Each such Subsidiary has the corporate or other power and
authority to own or hold under lease the properties it purports to own or hold
under lease and to transact the business it transacts and proposes to transact.

     (d) No Subsidiary is a party to, or otherwise subject to any legal
restriction or any agreement (other than the Amended and Restated Note Purchase
Agreements, the Notes, the agreements listed on Schedule 5.4 and customary
limitations imposed by corporate law and insurance regulatory statutes or other
statutes governing the organization of legal entities) restricting the ability
of such Subsidiary to pay dividends out of profits or make any other similar
distributions of profits to the Parent Company or any of its Subsidiaries that
owns any outstanding share capital or similar equity interests of such
Subsidiary.

     Section 5.5. Financial Statements. The Parent Company has delivered to each
Noteholder copies of the financial statements of the Parent Company and its
Subsidiaries listed on Schedule 5.5. All of said financial statements (including
in each case the related schedules and notes) fairly present, in all material
respects, the consolidated financial position of the Parent Company and its
Subsidiaries as of the respective dates specified in such Schedule and the
consolidated results of their operations and cash flows for the respective
periods so specified and have been prepared in accordance with GAAP consistently
applied throughout the periods involved except as set forth in the notes thereto
(subject, in the case of any interim financial statements, to normal year-end
adjustments).

     Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution,
delivery and performance by the Parent Company of this Guaranty and the
consummation of the Reorganization will not (a) contravene, result in any breach
of, or constitute a default under, or


                                      -14-



result in the creation of any Lien in respect of any property of the Parent
Company or any Subsidiary under, any indenture, mortgage, deed of trust, loan,
purchase or credit agreement, lease, corporate charter or by-laws, or any other
Material agreement or instrument to which the Parent Company or any Subsidiary
is bound or by which the Parent Company or any Subsidiary or any of their
respective properties may be bound or affected, (b) conflict with or result in a
breach of any of the terms, conditions or provisions of any order, judgment,
decree or ruling of any court, arbitrator or Governmental Authority applicable
to the Parent Company or any Subsidiary or (c) violate any provision of any
statute or other rule or regulation of any Governmental Authority applicable to
the Parent Company or any Subsidiary.

     Section 5.7. Governmental Authorizations, Etc. No consent, approval or
authorization of, or registration, filing or declaration with, any Governmental
Authority is required in connection with the execution, delivery or performance
by the Parent Company of this Guaranty or the consummation of the
Reorganization, other than those consents, approvals or authorizations obtained
and those registrations, filings or declarations made on or before the Effective
Date.

     Section 5.8. Litigation; Observance of Agreements, Statutes and Orders. (a)
Except as disclosed in the financial statements described in Schedule 5.5, there
are no actions, suits or other proceedings pending or, to the knowledge of the
Parent Company, threatened against or affecting the Parent Company or any
Subsidiary or any property of the Parent Company or any Subsidiary in any court
or before any arbitrator of any kind or before or by any Governmental Authority
that, individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect.

     (b) Neither the Parent Company nor any Subsidiary is in default under any
term of any agreement or instrument to which it is a party or by which it is
bound, or any order, judgment, decree or ruling of any court, arbitrator or
Governmental Authority or is in violation of any applicable law, ordinance, rule
or regulation (including, without limitation, Environmental Laws) of any
Governmental Authority, which default or violation, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

     Section 5.9. Taxes. The Parent Company and its Subsidiaries have filed all
income tax returns that are required to have been filed in any jurisdiction, and
have paid all taxes shown to be due and payable on such returns and all other
taxes and assessments levied upon them or their properties, assets, income or
franchises, to the extent such taxes and assessments have become due and payable
and before they have become delinquent, except for any taxes and assessments (a)
the amount of which is not, individually or in the aggregate, Material or (b)
the amount, applicability or validity of which is currently being contested in
good faith by appropriate proceedings and with respect to which the Parent
Company or a Subsidiary, as the case may be, has established adequate reserves
in accordance with GAAP. The Parent Company knows of no basis for any other tax
or assessment that could reasonably be expected to have a Material Adverse
Effect. The charges, accruals and reserves on the books of the Parent Company
and its Subsidiaries in respect of United States and Canadian federal, state,
provincial or other taxes for all fiscal periods are adequate. The Canadian
federal and provincial income tax liabilities of the Parent Company and its
Subsidiaries have been determined by the Canadian Customs and


                                      -15-


Revenue Agency and corresponding provincial taxing authorities by the issuance
of notices of assessment for all fiscal years up to and including the fiscal
year ended December 31, 2004, and the Parent Company and its Subsidiaries have
paid any taxes indicated to be owing on such notices of assessment. The United
States federal income tax liabilities of the Parent Company and its Subsidiaries
have been determined by the Internal Revenue Service and paid for all fiscal
years up to and including the fiscal year ended December 31, 2004.

     Section 5.10. Title to Property; Leases. The Parent Company and its
Subsidiaries have good and sufficient title to their respective properties that,
individually or in the aggregate, are Material, including all such properties
reflected in the most recent audited balance sheet referred to in Section 5.5 or
purported to have been acquired by the Parent Company or any Subsidiary after
said date (except as sold or otherwise disposed of in the ordinary course of
business), in each case free and clear of Liens prohibited by this Guaranty. All
leases that, individually or in the aggregate, are Material are valid and
subsisting and are in full force and effect in all material respects.

     Section 5.11. Licenses, Permits, Etc. Except as disclosed in the financial
statements described in Schedule 5.5,

          (a) the Parent Company and its Subsidiaries own, possess or are
     licensed to use all licenses, permits, franchises, authorizations, patents,
     copyrights, service marks, trademarks, trade names and domain names, or
     rights thereto, that, individually or in the aggregate, are Material,
     without known conflict with the rights of others;

          (b) to the best knowledge of the Parent Company, no product of the
     Parent Company infringes in any material respect any license, permit,
     franchise, authorization, patent, copyright, service mark, trademark, trade
     name, domain name or other right owned by any other Person; and

          (c) to the best knowledge of the Parent Company, there is no Material
     violation by any Person of any right of the Parent Company or any of its
     Subsidiaries with respect to any patent, copyright, service mark,
     trademark, trade name, domain name or other right owned or used by the
     Parent Company or any of its Subsidiaries.

     Section 5.12. Compliance with ERISA. (a) All Canadian pension plans of the
Parent Company and its Subsidiaries have been established, operated,
administered and maintained in compliance with all applicable laws, regulations
and orders applicable thereto except where the failure to comply could not
reasonably be expected to have a Material Adverse Effect. All premiums,
contributions and any other amounts required by applicable Canadian pension plan
documents or applicable laws have been paid or accrued as required, except where
the failure to pay such premiums, contributions and amounts could not reasonably
be expected to have a Material Adverse Effect.

     (b) The Parent Company and each ERISA Affiliate have operated and
administered each employee benefit plan (as defined in Section 3(3) of ERISA) in
compliance with all applicable laws except for such instances of noncompliance
as have not resulted in and could not


                                      -16-



reasonably be expected to result in a Material Adverse Effect. Neither the
Parent Company nor any ERISA Affiliate has incurred any liability pursuant to
Title I or IV of ERISA or the penalty or excise tax provisions of the Code
relating to employee benefit plans (as defined in Section 3 of ERISA), and no
event, transaction or condition has occurred or exists that could reasonably be
expected to result in the incurrence of any such liability by the Parent Company
or any ERISA Affiliate, or in the imposition of any Lien on any of the rights,
properties or assets of the Parent Company or any ERISA Affiliate, in either
case pursuant to Title I or IV of ERISA or to such penalty or excise tax
provisions or to Section 401(a)(29) or 412 of the Code, other than such
liabilities or Liens as could not, individually or in the aggregate, reasonably
be expected to result in a Material Adverse Effect.

     (c) The present value of the aggregate benefit liabilities under each of
the Plans (other than Multiemployer Plans), determined as of the end of such
Plan's most recently ended plan year on the basis of the actuarial assumptions
specified for funding purposes in such Plan's most recent actuarial valuation
report, did not exceed the aggregate current value of the assets of such Plan
allocable to such benefit liabilities by more than $1,000,000 in the aggregate
for all Plans. The term "benefit liabilities" has the meaning specified in
Section 4001 of ERISA and the terms "current value" and "present value" have the
meanings specified in Section 3 of ERISA.

     (d) The Parent Company and its ERISA Affiliates have not incurred
withdrawal liabilities (and are not subject to contingent withdrawal
liabilities) under Section 4201 or 4204 of ERISA in respect of Multiemployer
Plans that could, individually or in the aggregate, reasonably be expected to
result in a Material Adverse Effect.

     (e) The expected post-retirement benefit obligation (determined as of the
last day of the Parent Company's most recently ended fiscal year in accordance
with Financial Accounting Standards Board Statement No. 106, without regard to
liabilities attributable to continuation coverage mandated by Section 4980B of
the Code) of the Parent Company and its Subsidiaries is not Material.

     (f) The execution and delivery of this Guaranty will not involve any
transaction that is subject to the prohibitions of Section 406(a) of ERISA or in
connection with which a tax could be imposed pursuant to Section
4975(c)(1)(A)-(D) of the Code for which an exemption is not available. The
representation by the Parent Company in the first sentence of this Section
5.12(f) is made in reliance upon and subject to the accuracy of each
Noteholder's representation in Section 6.2 of the Amended and Restated Note
Purchase Agreements.

     Section 5.13. Private Offering by the Parent Company. Neither the Parent
Company nor anyone acting on its behalf has offered the Notes or any similar
securities for sale to, or solicited any offer to buy any of the same from, or
otherwise approached or negotiated in respect thereof with, any Person other
than the Noteholders and not more than 45 other Institutional Investors of the
types described in clause (c) of the definition thereof, each of which has been
offered the Notes at a private sale for investment. Neither the Parent Company
nor anyone acting on its behalf has taken, or will take, any action that would
subject the issuance or sale of the Notes to the registration requirements of
Section 5 of the Securities Act or the prospectus and registration requirements
of securities legislation of any of the provinces or territories of Canada.


                                      -17-



     Section 5.14. [Intentionally Omitted].

     Section 5.15. Existing Debt; Future Liens. (a) Except as described therein,
the financial statements described therein, the financial statements described
in Schedule 5.5 set forth a complete and correct list of all outstanding Debt of
the Parent Company and its Subsidiaries as of December 31, 2005 since which date
there has been no Material change in the amounts, interest rates, sinking funds,
installment payments or maturities of the Debt of the Parent Company or its
Subsidiaries. Neither the Parent Company nor any Subsidiary is in default and no
waiver of default is currently in effect, in the payment of any principal or
interest on any Debt of the Parent Company or such Subsidiary and no event or
condition exists with respect to any Debt of the Parent Company or any
Subsidiary that would permit (or that with notice or the lapse of time, or both,
would permit) one or more Persons to cause such Debt to become due and payable
before its stated maturity or before its regularly scheduled dates of payment.

     (b) Except as disclosed in the financial statements described in Schedule
5.5, neither the Parent Company nor any Subsidiary has agreed or consented to
cause or permit in the future (upon the happening of a contingency or otherwise)
any of its property, whether now owned or hereafter acquired, to be subject to a
Lien not permitted by Section 10.3 of the Note Purchase Agreement.

     Section 5.16. Foreign Assets Control Regulations, Etc. The Parent Company's
execution, delivery and performance of this Guaranty and the consummation of the
Reorganization will not violate the Anti-Terrorism Order, the Patriot Act or the
Trading with the Enemy Act, as amended, or any of the foreign assets control
regulations of the United States Treasury Department (31 CFR, Subtitle B,
Chapter V, as amended) or any enabling legislation or executive order relating
thereto.

     Section 5.17. Status under Certain Statutes. Neither the Parent Company nor
any Subsidiary is required to be registered under the Investment Company Act of
1940, as amended, the Public Utility Holding Company Act of 1935, as amended,
the ICC Termination Act of 1995, as amended, or the Federal Power Act, as
amended.

     Section 5.18. Environmental Matters. Neither the Parent Company nor any
Subsidiary has knowledge of any claim or has received any notice of any claim,
and no proceeding has been instituted raising any claim against the Parent
Company or any of its Subsidiaries or any of their respective real properties
now or formerly owned, leased or operated by any of them or other assets,
alleging any damage to the environment or violation of any Environmental Laws,
except, in each case, such as could not reasonably be expected to result in a
Material Adverse Effect. Except as otherwise disclosed to each Noteholder in
writing:

          (a) neither the Parent Company nor any Subsidiary has knowledge of any
     facts which would give rise to any claim, public or private, of violation
     of Environmental Laws or damage to the environment emanating from,
     occurring on or in any way related to real properties now or formerly
     owned, leased or operated by any of them or to other assets or their use,
     except, in each case, such as could not reasonably be expected to result in
     a Material Adverse Effect;


                                      -18-



          (b) neither the Parent Company nor any of its Subsidiaries has stored
     any Hazardous Materials on real properties now or formerly owned, leased or
     operated by any of them or has disposed of any Hazardous Materials in a
     manner contrary to any Environmental Laws in each case in any manner that
     could reasonably be expected to result in a Material Adverse Effect; and

          (c) all buildings on all real properties now owned, leased or operated
     by the Parent Company or any of its Subsidiaries are in compliance with
     applicable Environmental Laws, except where failure to comply could not
     reasonably be expected to result in a Material Adverse Effect.

     Section 5.19. Guaranty Ranks Pari Passu. The obligations of the Parent
Company under this Guaranty rank at least pari passu in right of payment with
all other Senior Debt (actual or contingent) of the Parent Company, including,
without limitation, all Senior Debt of the Parent Company described in Schedule
5.15.

     Section 5.20. Permitted Senior Indebtedness. The obligations of the Parent
Company under this Guaranty constitute Permitted Senior Indebtedness, as defined
in the Subordinated Debentures.

SECTION 6. PAYMENTS FREE AND CLEAR OF TAXES.

     (a) The Parent Company, for the benefit of the holders of the Notes, agrees
that in the event payments, if any, made by the Parent Company hereunder to any
holder of the Notes are subject to any present or future tax, duty, assessment,
impost, levy, withholding or other similar charge (a "Relevant Tax") imposed
upon such Noteholder by the government of any country or jurisdiction (or any
authority or political subdivision therein or thereof) other than any tax based
on or measured by net income or capital imposed on any Noteholder by the country
in which such Noteholder is a resident for income tax purposes (the "Resident
Country"), from or through which payments hereunder or on or in respect of the
Notes are actually made (each a "Taxing Jurisdiction"), the Parent Company will
pay to such Noteholder such additional amounts ("Tax Indemnity Amounts") as may
be necessary in order that the net amounts paid to such Noteholder pursuant to
the terms of this Guaranty after imposition of any such Relevant Tax shall be
not less than the amounts specified in the Amended and Restated Note Purchase
Agreements or the Notes to be then due and payable (after giving effect to the
exclusion for Relevant Taxes imposed by the government of the Resident Country),
provided that the Parent Company shall not be obliged to pay such Tax Indemnity
Amounts to any holder of a Note in respect of Relevant Taxes to the extent such
Relevant Taxes exceed the Relevant Taxes that would have been payable:

          (1) had such Noteholder not been a resident of Canada within the
     meaning of the Income Tax Act (Canada) or not used or held such Note in the
     course of carrying on a business in Canada within the meaning of the Income
     Tax Act (Canada); or

          (2) had such Noteholder not dealt with the Parent Company on a
     non-arm's length basis (within the meaning of the Income Tax Act (Canada))
     in connection with any such payment; or


                                      -19-



          (3) had such Noteholder not had any connection with such Taxing
     Jurisdiction or any territory or political subdivision thereof other than
     the mere holding of a Note (or the receipt of any payments in respect
     thereof) or activities incidental thereto (including enforcement thereof);
     or

          (4) but for the delay or failure by such Noteholder (following a
     written request by the Parent Company) in the filing with an appropriate
     Governmental Authority or otherwise of forms, certificates, documents,
     applications or other reasonably required evidence, that is required to be
     filed by such Noteholder to avoid or reduce such Relevant Taxes and that in
     the case of any of the foregoing would not result in any confidential or
     proprietary income tax return information being revealed, either directly
     or indirectly, to any Person (collectively, "Forms") and such delay or
     failure could have been lawfully avoided by such Noteholder, provided that
     such Noteholder shall be deemed to have satisfied the requirements of this
     clause (4) upon the good faith completion and submission of such Forms as
     may be specified in a written request of the Parent Company no later than
     45 days after receipt by such Noteholder of such written request (which
     written request shall be accompanied by a copy of such Forms and all
     applicable instructions and, if any such Forms or instructions shall not be
     in the English language, an English translation thereof);

and provided further that in no event shall the Parent Company be obligated to
pay any Tax Indemnity Amount to any holder not resident for income tax purposes
in the United States of America or any other jurisdiction in which an original
Noteholder is resident for tax purposes on the date of Closing in excess of the
amounts that the Company would have been obligated to pay if such holder had
been a resident of the United States of America or such other jurisdiction, as
applicable, for income tax purposes for purposes of, and eligible for the
benefits of, any double taxation treaty from time to time in effect between the
United States of America or such other jurisdiction and the relevant Taxing
Jurisdiction

     (b) Within 60 days after the date of any payment by the Parent Company of
any Relevant Tax in respect of any payment under this Guaranty, the Parent
Company shall furnish to each holder of a Note the original tax receipt for the
payment of such Relevant Tax (or if such original tax receipt is not available,
such other evidence as may be acceptable to the holders of the Notes), together
with such other documentary evidence with respect to such payments as may be
reasonably requested from time to time by any holder of a Note.

     (c) If the Parent Company has made a payment to or on account of any holder
of a Note pursuant to Section 6(a) above and such Noteholder, in such
Noteholder's reasonable discretion, determines that it is entitled to a refund
of the Relevant Tax to which such payment is attributable from the Governmental
Authority to which the payment of the Relevant Tax was made and such refund can
be obtained by filing one or more Forms, then (i) such Noteholder shall, as soon
as practicable after receiving a written request therefor from the Parent
Company (which request shall specify in reasonable detail the Forms to be
filed), file such Forms and (ii) upon receipt of such refund, if any, provided
no Default or Event of Default then exists, promptly pay over such refund to the
Parent Company.


                                      -20-



     For the avoidance of doubt, nothing herein shall (a) restrict the right of
any holder of the Notes to arrange its tax affairs as it shall deem appropriate
or (b) require any holder of the Notes to disclose any information regarding its
tax affairs or computations to the Parent Company or any other Person other than
as shall be necessary to permit the Parent Company to determine whether the
payment of any Tax Indemnity Amount would be required to be made pursuant to the
provisions of this Section 6; provided, however, no holder of the Notes shall be
obligated to disclose any of its tax returns to the Parent Company or any other
Person.

SECTION 7. EXPENSES, ETC.

     Section 7.1. Transaction Expenses. Whether or not the transactions
contemplated hereby are consummated, the Parent Company will pay all reasonable
costs and expenses (including reasonable attorneys' fees of a special counsel
and, if reasonably required, local or other counsel) incurred by each holder of
the Notes in connection with such transactions and any amendments, waivers or
consents under or in respect of this Guaranty or the Amended and Restated Note
Purchase Agreements (whether or not such amendment, waiver or consent becomes
effective), including, without limitation: (a) the reasonable costs and expenses
incurred in enforcing or defending (or determining whether or how to enforce or
defend) any rights under this Guaranty or in responding to any subpoena or other
legal process or informal investigative demand issued in connection with this
Guaranty, or by reason of being a Noteholder, and (b) the reasonable costs and
expenses, including reasonable financial advisors' fees, incurred in connection
with the insolvency or bankruptcy of the Parent Company or any Subsidiary or in
connection with any work-out or restructuring of the transactions contemplated
hereby and by the Notes or the Amended and Restated Note Purchase Agreements.
The Parent Company will pay, and will save each holder of the Notes harmless
from, all claims in respect of any fees, costs or expenses, if any, of brokers
and finders (other than those retained by such Person).

     Section 7.2. Survival. The obligations of the Parent Company under this
Section 7 will survive the payment or transfer of any Note, the enforcement,
amendment or waiver of any provision of this Guaranty, the Amended and Restated
Note Purchase Agreements or the Notes, and the termination of this Guaranty.


                                      -21-



SECTION 8. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

     All representations and warranties contained herein shall survive the
execution and delivery of this Guaranty, the purchase or transfer by any
subsequent holder of any Note or portion thereof or interest therein and the
payment of any Note, and may be relied upon by any subsequent Noteholder,
regardless of any investigation made at any time by or on behalf of any
subsequent Noteholder. All statements contained in any certificate or other
instrument delivered by or on behalf of the Parent Company pursuant to this
Guaranty shall be deemed representations and warranties of the Parent Company
under this Guaranty. Subject to the preceding sentence, this Guaranty embodies
the entire agreement and understanding between the holders of the Notes and the
Parent Company and supersede all prior agreements and understandings relating to
the subject matter hereof.

SECTION 9. AMENDMENT AND WAIVER.

     Section 9.1. Requirements. This Guaranty may be amended, and the observance
of any term hereof or of the Notes may be waived (either retroactively or
prospectively), with (and only with) the written consent of the Parent Company
(except amendments which occur pursuant to Section 4.3 hereof) and any
Noteholder or Noteholders of not less than 51% in principal amount of Notes at
the time outstanding, except that no such amendment or waiver may, without the
written consent of the holder of each Note at the time outstanding affected
thereby, amend any of Sections 2, 6 or 9 hereof.

     Section 9.2. Solicitation of Holders of Notes.

     (a) Solicitation. The Parent Company will provide each holder of the Notes
(irrespective of the amount of Notes then owned by it) with sufficient
information, sufficiently far in advance of the date a decision is required, to
enable such Noteholder to make an informed and considered decision with respect
to any proposed amendment, waiver or consent in respect of any of the provisions
hereof. The Parent Company will deliver executed or true and correct copies of
each amendment, waiver or consent effected pursuant to the provisions of this
Section 9 to each holder of outstanding Notes promptly following the date on
which it is executed and delivered by, or receives the consent or approval of,
the requisite holders of Notes.

     (b) Payment. The Parent Company will not directly or indirectly pay or
cause to be paid any remuneration, whether by way of supplemental or additional
interest, fee or otherwise, or grant any security, to any Noteholder as
consideration for or as an inducement to the entering into by such Noteholder of
any waiver or amendment of any of the terms and provisions hereof, unless such
remuneration is concurrently paid, or security is concurrently granted, on the
same terms, ratably to each Noteholder even if such Noteholder did not consent
to such waiver or amendment.

     Section 9.3. Binding Effect, Etc. Any amendment or waiver consented to as
provided in this Section 9 applies equally to all holders of Notes affected
thereby and is binding upon them and upon each future holder of any Note and
upon the Parent Company without regard to whether such Note has been marked to
indicate such amendment or waiver. No such amendment


                                      -22-



or waiver will extend to or affect any obligation, covenant, agreement, Default
or Event of Default not expressly amended or waived or impair any right
consequent thereon. No course of dealing between the Parent Company and the
holder of any Note nor any delay in exercising any rights hereunder or under any
Note shall operate as a waiver of any rights of any holder of such Note. As used
herein, the term "this Guaranty" and references thereto shall mean this Guaranty
as it may from time to time be amended or supplemented.

     Section 9.4. Notes Held by Parent Company, Etc. Solely for the purpose of
determining whether the Noteholders of the requisite percentage of the aggregate
principal amount of Notes then outstanding approved or consented to any
amendment, waiver or consent to be given under this Guaranty, or have directed
the taking of any action provided herein or in the Notes to be taken upon the
direction of the Noteholders of a specified percentage of the aggregate
principal amount of Notes then outstanding, Notes directly or indirectly owned
by the Parent Company or any of its Subsidiaries or Affiliates shall be deemed
not to be outstanding.

SECTION 10. NOTICES.

     All notices and communications provided for hereunder shall be in writing
and sent (a) by facsimile if the sender on the same day sends a confirming copy
of such notice by a recognized overnight delivery service (charges prepaid), or
(b) by registered or certified mail with return receipt requested (postage
prepaid), or (c) by a recognized overnight delivery service (charges prepaid).
Any such notice must be sent:

          (1) if to a Noteholder as of the Effective Date or its nominee, to
     such Noteholder or its nominee at the address specified for such
     communications in Schedule A to the Amended and Restated Note Purchase
     Agreements, or at such other address as such Noteholder or its nominee
     shall have specified to the Parent Company in writing,

          (2) if to any other holder of any Note, to such Noteholder at such
     address as such other holder shall have specified to the Parent Company in
     writing, or

          (3) if to the Parent Company, to Hub International Limited, 55 East
     Jackson Boulevard, Chicago, Illinois, 60604, Attention: Marianne Paine,
     Chief Legal Officer, or at such other address as the Parent Company shall
     have specified to the holder of each Note in writing.

Notices under this Section 10 will be deemed given only when actually received.

SECTION 11. REPRODUCTION OF DOCUMENTS.

     This Guaranty and all documents relating hereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by each Noteholder on the Effective Date, and
(c) financial statements, certificates and other information previously or
hereafter furnished to any holder of the Notes, may be reproduced by such
Noteholder by any photographic, photostatic, microfilm, microcard, miniature
photographic or other similar process and such Noteholder may destroy any
original document so reproduced.


                                      -23-



To the extent permitted by applicable law, any such reproduction shall be
admissible in evidence as the original itself in any judicial or administrative
proceeding (whether or not the original is in existence and whether or not such
reproduction was made by such Noteholder in the regular course of business) and
any enlargement, facsimile or further reproduction of such reproduction shall
likewise be admissible in evidence. This Section 11 shall not prohibit the
Parent Company or any other holder of Notes from contesting any such
reproduction to the same extent that it could contest the original, or from
introducing evidence to demonstrate the inaccuracy of any such reproduction.

SECTION 12. SUBMISSION TO JURISDICTION, JUDGMENTS, ETC.

     Section 12.1. Submission to Jurisdiction. The Parent Company hereby
irrevocably consents and submits to the non-exclusive jurisdiction of any court
located within the State of New York sitting in the Borough of Manhattan and the
United States District Court for the Southern District of New York and
irrevocably agrees that all actions or proceedings relating to this Guaranty may
be litigated in such courts and the Parent Company irrevocably waives any
objection which it may have based on improper venue or forum non conveniens to
the conduct of any proceeding in any such court. The Parent Company hereby
irrevocably appoints, with respect to any suit or proceeding that may be
initiated hereunder, Hub International Northeast, Inc. as the Parent Company's
agent for the purpose of accepting service of process within the State of New
York and agrees to retain and consents that all such service of process be made

Boulevard, Chicago, Illinois, 60604 or at such other address of Hub
International Northeast located in the State of New York, as may be designated
by the Parent Company by notice to each Noteholder and that service so made
shall be deemed to be completed upon the earlier of actual receipt or three
Business Days after the same shall have been posted to the Parent Company.
Nothing contained in this Section 12.1 shall affect the right of any holder of
the Notes to serve legal process in any other manner permitted by law or to
bring any action or proceeding in the courts of any jurisdiction against the
Parent Company or to enforce a judgment obtained in the courts of any other
jurisdiction.

     Section 12.2. Judgments. Any payment made by the Parent Company to any
holder of the Notes or for the account of any such Noteholder in respect of any
amount payable by the Parent Company in lawful currency of the United States of
America, which payment is made in a foreign currency, whether pursuant to any
judgment or order of a court or tribunal or otherwise, shall constitute a
discharge of the obligations of the Parent Company only to the extent of the
amount of lawful currency of the United States of America which may be purchased
with such other foreign currency on the day of payment. The Parent Company
shall, as a separate and independent obligation, which shall not be merged in
any such judgment or order, pay or cause to be paid the amount payable in lawful
currency of the United States of America and not so discharged in accordance
with the foregoing.


                                      -24-



SECTION 13. MISCELLANEOUS.

     Section 13.1. Successors and Assigns. All covenants and other agreements
contained in this Guaranty by or on behalf of any of the parties hereto bind and
inure to the benefit of their respective successors and assigns (including,
without limitation, any subsequent holder of a Note) whether so expressed or
not.

     Section 13.2. Payments Due on Non-Business Days. Anything in this Guaranty
to the contrary notwithstanding, any payment of principal of or Make-Whole

additional days elapsed in the computation of the interest payable on such next
succeeding Business Day.

     Section 13.3. Severability. Any provision of this Guaranty that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall (to the full extent permitted by law)
not invalidate or render unenforceable such provision in any other jurisdiction.

     Section 13.4. Construction. (a) Each covenant contained herein shall be
construed (absent express provision to the contrary) as being independent of
each other covenant contained herein, so that compliance with any one covenant
shall not (absent such an express contrary provision) be deemed to excuse
compliance with any other covenant. Where any provision herein refers to action
to be taken by any Person, or which such Person is prohibited from taking, such
provision shall be applicable whether such action is taken directly or
indirectly by such Person.

     (b) Where the character or amount of any asset or liability or item of
income or expense is required to be determined or any consolidation or other
accounting computation is required to be made for the purposes of this Guaranty,
the same shall be done in accordance with GAAP, to the extent applicable, except
where such principles are inconsistent with the requirements of this Guaranty.

     Section 13.5. Counterparts. This Guaranty may be executed in any number of
counterparts, each of which shall be an original but all of which together shall
constitute one instrument. Each counterpart may consist of a number of copies
hereof, each signed by less than all, but together signed by all, of the parties
