          (c)  The entries made in the Register to the extent permitted by
applicable law, shall be prima facie evidence of the existence and amounts
of the obligations of the Company therein recorded; provided, however, that
the failure of the Lender to maintain the Register, or any error therein,
shall not in any manner affect the obligation of the Company to

                                    24

<PAGE>

repay (with applicable interest) the Loan made to the Company by the Lender
in accordance with the terms of this Agreement.

          (d)  The Company agrees that, upon the request of the Lender, the
Company will execute and deliver to the Lender the Note evidencing the
Loan, with appropriate insertions as to date and principal amount.

                                 ARTICLE 3

                      Representations and Warranties

          In order to induce the Lender to enter into this Agreement and to
make the Loan, the Company hereby represents and warrants to the Lender, as
follows (all representations and warranties are made with respect to the
Closing Date and with respect to the entire period following the Closing
Date during which any amounts are due and owing from the Company to the
Lender hereunder, as if made at any time during such period):

          SECTION 3.01. No Change.  There has been no change, and no
development or event involving a prospective change, which has had or could
reasonably be expected to have a material adverse effect on the business,
assets, condition (financial or otherwise) or results of operations of, the
Company and its Subsidiaries taken as a whole.

          SECTION 3.02. Corporate Existence; Compliance with Law.  Except
for those exceptions to the following which the Lender has actual knowledge
of on the Closing Date, each of the Company and its Subsidiaries (a) is a
corporation duly organized and validly existing under the laws of the
jurisdiction of its incorporation, (b) has full corporate power and
authority and possesses all governmental franchises, licenses, permits,
authorizations and approvals necessary to enable it to use its corporate
name and to own, lease or otherwise hold its properties and assets and to
carry on its business as presently conducted other than such franchises,
licenses, permits, authorizations and approvals the lack of which,
individually or in the aggregate, would not have a material adverse effect
on the business, assets, condition (financial or otherwise) or results of
operations of the Company and its Subsidiaries, taken as a whole, (c) is
duly qualified and in good standing to do business in each jurisdiction in
which the nature of its business or the ownership, leasing or holding of
its properties makes such qualification necessary, except such
jurisdictions where the failure so to qualify would not have a material
adverse effect on the business, assets, condition (financial or otherwise)
or results of operations of the Company and its Subsidiaries,

                                    25

<PAGE>

taken as a whole, and (d) is in compliance with all applicable statutes,
laws, ordinances, rules, orders, permits and regulations of any
Governmental Authority (including those related to Hazardous Materials and
substances), except where noncompliance would not have a material adverse
effect on the business, assets, condition (financial or otherwise) or
results of operations of the Company and its Subsidiaries, taken as a
whole.  Neither the Company nor any of its Subsidiaries has received any
written communication from a Governmental Authority that alleges that the
Company or any of its Subsidiaries is not in compliance, in all material
respects, with all material federal, state, local or foreign laws,
ordinances, rules and regulations.

          SECTION 3.03.  Corporate Power; Authorization.  Each of the
Company and its Subsidiaries has the corporate power and authority to make,
deliver and perform each of the Credit Documents to which it is a party,
and the Company has the corporate power and authority and legal right to
borrow hereunder.  Each of the Company and its Subsidiaries has taken all
necessary corporate action to authorize the execution, delivery and
performance of each of the Credit Documents to which it is or will be a
party and the Company has taken all necessary corporate action to authorize
the borrowings hereunder.  No consent or authorization of, or filing with,
any Person (including any Governmental Authority) is required in connection
with the execution, delivery or performance by the Company or any of the
Company's Subsidiaries, or for the validity or enforceability against the
Company or any of the Company's Subsidiaries, of any Credit Document except
for consents, authorizations and filings (a) which have been obtained or
made and are in full force and effect, and except such consents,
authorizations and filings, the failure to obtain or perform (i) which
would not have a material adverse effect on the business, assets, condition
(financial or otherwise) or results of operations of the Company and its
Subsidiaries taken as a whole and (ii) which would not adversely affect the
validity or enforceability of any of the Credit Documents or the rights or
remedies of the Lender thereunder.

          SECTION 3.04.  Enforceable Obligations.  This Agreement, and each
of the other Credit Documents has been, duly executed and delivered on
behalf of the Company.  This Agreement and each of the other Credit
Documents constitutes the legal, valid and binding obligation of the
Company, and is enforceable against the Company in accordance with its
terms, except as may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or similar laws affecting creditors' rights
generally and by general principles of equity (regardless of whether
enforcement is sought in a proceeding in equity or at law).

                                    26

<PAGE>

          SECTION 3.05. No Legal Bar.  The execution, delivery and
performance of each Credit Document and the incurrence or issuance of and
use of the proceeds of the Loan do not violate any Requirement of Law or
any Contractual obligation applicable to or binding upon the Company or any
Subsidiary of the Company or any of their respective properties or assets,
in any manner which, individually or in the aggregate, (i) would have a
material adverse effect on the ability of the Company or any such
Subsidiary to perform its obligations under the Credit Documents to which
it is a party, (ii) would give rise to any liability on the part of the
Lender, or (iii) would have a material adverse effect on the business,
assets, condition (financial or otherwise) or results of operations of the
Company and its Subsidiaries taken as a whole, and do not result in the
creation or imposition of any Lien on any of its properties or assets
pursuant to any Requirement of Law applicable to it, as the case may be, or
any of its Contractual Obligations, except for Permitted Liens.

          SECTION 3.06. No Material Litigation.  No litigation by,
investigation known to the company by, or proceeding of, any Governmental
Authority is pending against the Company or any of its Subsidiaries with
respect to the validity, binding effect or enforceability of any Credit
Document, the Loan made hereunder or the use of proceeds thereof.  No
lawsuits, claims, proceedings or investigations pending or, to the best
knowledge of the Company, threatened against or affecting the Company or a
subsidiary of the Company or any of their respective properties, assets,
operations or businesses, in which there is a probability of an adverse
determination that is reasonably likely, if adversely decided, to have a
material adverse effect on the business, assets, condition (financial or
otherwise) or results of operations of the Company and its Subsidiaries,
taken as a whole.

          SECTION 3.07. Investment Company Act.  Neither the company nor
any Subsidiary of the Company is an "investment company" or a company
"controlled" by an "investment company" (as each of the quoted terms is
defined or used in the Investment Company Act of 1940, as amended).

          SECTION 3.08. Federal Regulation.  No part of the proceeds of the
Loan are being or are to be used for any purpose which violates the
provisions of Regulation G, T, U or X of the Board of Governors of the
Federal Reserve System.  Neither the Company nor any of its Subsidiaries is
engaged or will engage, principally or as one of its important activities,
in the business of extending credit for the purpose of "purchasing" or
"carrying" any "margin stock"

                                    27

<PAGE>

within the respective meanings of each of the quoted terms under said
Regulation U.

          SECTION 3.09. No Default.  The Company and each of its
Subsidiaries have performed all material obligations required to be
performed by them under their respective Contractual obligations on and
after the Closing Date and they are not (with or without the lapse of time
or the giving of notice, or both) in breach or default in any respect
thereunder, except to the extent that such breach or default would not have
a material adverse effect on the business, assets, condition (financial or
otherwise) or results of operations of the Company and its Subsidiaries
taken as a whole.  Neither the Company nor any of its Subsidiaries is in
default under any material judgment, order or decree of any court,
administrative agency or commission or other governmental authority or
instrumentality, domestic or foreign, applicable to it or any of its
respective properties, assets, operations or business, except to the extent
that any such defaults would not, in the aggregate, have a material adverse
effect on the business, assets, condition (financial or otherwise) or
results of operations of the Company and its Subsidiaries, taken as a
whole.

          SECTION 3.10. Ownership of Property: Liens.  Each of the Company
and its Subsidiaries has good and valid title to all of its material
tangible and intangible personal property, in each case free and clear of
all mortgages, liens, security interests or encumbrances of any nature
whatsoever except Permitted Liens.  With respect to real property or
interests in real property, as of the Closing Date, each of the Company and
its Subsidiaries has (i) fee title to all of the real property listed on
Schedule 3.10 (each, a "Fee Property"), and (ii) good and valid title to
the leasehold estates in all of the real property leased by it and listed
on Schedule 3.10 under the heading "Leased Properties" (each, a "Leased
Property"), in each case free and clear of all mortgages, liens, security
interests, easements, covenants, rights-of-way and other similar
restrictions of any nature whatsoever, except (A) Permitted Liens, (B) any
conditions that may be shown by a current, accurate survey or physical
inspection of any Fee Property or Leased Property, (C) as to Leased
Property, the terms and provisions of the respective lease therefor and any
matters affecting the fee title and any estate superior to the leasehold
estate related thereto, and (D) title defects, or leases or subleases
granted to others, which are not material to the Fee Properties or the
Leased Properties, as the case may be, taken as a whole.  The Fee
Properties and the Leased Properties (collectively the "Real Properties")
constitute, as of the Closing Date, all of the real property owned in fee
or leased by the Company and its subsidiaries.

                                    28

<PAGE>

          SECTION 3.11. ERISA.  None of the Company, any Subsidiary of the
Company or any Commonly Controlled Entity would be liable for any amount
pursuant to Section 4062, 4063, 4064 or 4069 of ERISA, if any Single
Employer Plan were to terminate.  Neither the Company nor any Commonly
Controlled Entity has been involved in any transaction that would cause the
Company to be subject to liability with respect to a Plan to which the
Company or any Commonly Controlled Entity contributed or was obligated to
contribute during the six-year period ending on the date this
representation is made or deemed made under Section 4062, 4069 or 4212(c)
of ERISA.  Neither the Company nor any Commonly Controlled Entity has
incurred any material liability under Title IV of ERISA which could become
or remain a liability of the Company after the Closing Date.  None of the
Company, any Subsidiary of the Company, or any director, officer or
employee thereof, or any of the Plans (to the best knowledge of the Company
with respect to any Multiemployer Plan), or any trust created thereunder,
or any fiduciary thereof, has engaged in a transaction or taken any other
action or omitted to take any action involving any Plan which could
constitute a prohibited transaction within the meaning of Section 406 of
ERISA which is not otherwise exempted, or would cause it to be subject to
either a material liability or civil penalty assessed pursuant to Section
409 or 502 of ERISA or a material tax imposed pursuant to Section 4975 or
4976 of the Code.  Each of the Plans (to the best knowledge of the Company
with respect to any Multiemployer Plan) has been operated and administered
in all material respects in accordance with applicable laws, including but
not limited to ERISA and the Code.  There are no material pending or, to
the best knowledge of the Company, threatened claims by or on behalf of any
of the Plans or any fiduciary, by any employee or beneficiary covered under
any such Plan, or otherwise involving any such Plan or fiduciary (other
than routine claims for benefits).  No condition exists and no event has
occurred with respect to any Multiemployer Plan which presents a material
risk of a complete or partial withdrawal under Subtitle E of Title IV of
ERISA, nor has the Company or any Commonly Controlled Entity been notified
that any such Multiemployer Plan is insolvent or in reorganization within
the meaning of Section 4241 of ERISA.  Neither the Company nor any Commonly
Controlled Entity nor any Subsidiary has been a party to any transaction or
agreement to which the provisions of Section 4204 of ERISA were applicable.
Neither the Company nor any Commonly Controlled Entity nor any subsidiary
is obligated to contribute to a Multiemployer Plan, on behalf of any
current or former employee of the Company, any Commonly Controlled Entity
or any Subsidiary.  None of the Plans or any trust established thereunder
has incurred any "accumulated funding deficiency" (as defined in Section
302 of ERISA and Section 412 of the Code), whether or not waived, as of the
last day of the most recent fiscal year of each of the

                                    29

<PAGE>

Plans.  No contribution failure has occurred with respect to any Plan
sufficient to give rise to a lien under Section 302(f) of ERISA.

          SECTION 3.12. Copyrights, Patents, Trademarks and Licenses.  The
Company or a Subsidiary of the Company owns or has the right to use,
without payment to any other party, all material patents, patent
applications, trademarks (registered or unregistered), trade names, service
marks and copyrights owned, used or filed by or licensed to the Company and
its Subsidiaries.  To the best knowledge of the Company, no claims are
pending by any Person with respect to the ownership, validity,
enforceability or the Company's or any Subsidiary's use of any such
patents, patent applications, trademarks (registered or unregistered),
trade names, service marks, copyrights challenging or questioning the
validity or effectiveness of any of the foregoing, in any jurisdiction,
domestic or foreign.

          SECTION 3.13. Environmental Matters.

          (a)  To the best knowledge of the Company, the Real Properties do
not contain in, on or under including the soil and groundwater thereunder,
any Hazardous Materials in amounts or concentrations that constitute or
constituted a material violation of, or could reasonably give rise to
material liability under, Environmental Laws.

          (b)  To the best knowledge of the Company, the Real Properties
and all operations and facilities at the Real Properties are in material
compliance with all Environmental Laws, and there is no contamination or
violation of any Environmental Law which could materially interfere with
the continued operation of, or materially impair the fair salable value of,
the Real Properties.

          (c)  To the best knowledge of the Company, neither the Company
nor any of its Subsidiaries has received or is aware of any complaint,
notice of violation, alleged violation, or notice of investigation or of
potential liability under Environmental Laws with regard to the Real
Properties or the operations of the Company or its subsidiaries, nor does
the Company or any of its Subsidiaries have knowledge that any such action
is being contemplated, considered or threatened.

          (d)  To the best knowledge of the Company, Hazardous Materials
have not been generated, treated, stored, disposed of, at, on or under the
Real Properties, nor have any Hazardous Materials been transported from the
Real Properties, in material violation of or in a manner that could
reasonably give rise to liability under any Environmental Laws.

                                    30

<PAGE>

          (e)  There are no governmental administrative actions or judicial
proceedings pending or, to the knowledge of the Company and its
Subsidiaries, threatened, under any Environmental Law to which the Company
or any of its Subsidiaries is a party with respect to the Real Properties,
nor are there any consent decrees or other decrees, consent orders,
administrative orders or other orders, or other administrative or judicial
requirements, other than permits authorizing operations at facilities at
the Real Properties, outstanding under any Environmental Law with respect
to the Real Properties.

          The Company hereby agrees that, so long as the Loan remains
outstanding and unpaid, or any other amount is owing to the Lender

the Company shall cause each of its Subsidiaries to:

          SECTION 5.01. Financial Statements.  Furnish to the Lender:

Subsidiaries taken as a whole, or (ii) litigation, investigation or
proceeding which may exist at any time between the Company or any of its
Subsidiaries and any Governmental Authority, or receipt of any notice of

<PAGE>

reasonably result in material liability to the Company and its Subsidiaries
taken as a whole, and in addition to such notice, deliver to the Lender

Responsible officer of the Company setting forth details as to such
Reportable Event and the action that the Company or such Commonly

referred to therein and (in the cases of clauses (a) through (d)) stating

Environmental Laws and obtain and comply with and maintain, and require
that all tenants and subtenants obtain and comply with and maintain, any
and all licenses, approvals, registrations or permits required by

have any reasonable likelihood of having a material adverse effect on the

operations of the Company and its Subsidiaries taken as a whole or on the
validity or enforceability of any of the Credit Documents or the rights and
remedies of the Lender thereunder;

penalties, fines, liabilities, settlements, damages, costs and expenses of
whatever kind or nature known or unknown, contingent or otherwise, arising
out of, or in any way relating to Hazardous Material or Environmental Laws,
including any orders, requirements or demands of Governmental Authorities
related thereto, including reasonable attorney's and consultant's fees,

          (C)  consents to the appointment of a Custodian of it or for any
substantial part of its property; or

          (D)  makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to

          (9)  a court of competent jurisdiction enters an order or decree
under any Bankruptcy Law that:

          (A)  is for relief against the Company or any Subsidiary in an
involuntary case;

          (B)  appoints a Custodian of the Company or any subsidiary or for
any substantial part of its property; or

          (C) orders the winding up or liquidation of the Company or any
Subsidiary;

or any similar relief is granted under any foreign laws and the order or
decree remains unstayed and in effect for 60 days;

          (10) any judgment or decree for the payment of money in excess of
$2,000,000 or its foreign currency equivalent at the time is entered
against the Company or any Subsidiary and is not discharged and either (A)
an enforcement proceeding has been commenced by any creditor upon such
judgment or decree or (B) there is a period of 60 days following the entry
of such judgment or decree during which such judgment or decree is not
discharged, waived or the execution thereof stayed;

          (11) (i) any Person shall engage in any "prohibited transaction"
(as defined in Section 4.06 of ERISA or Section 4975 of the Code) involving
any Plan which is not otherwise exempted, (ii) any "accumulated funding

<PAGE>

Company or any Commonly Controlled Entity shall, or in the reasonable
opinion of the Lender is likely to, incur any liability in connection with
a withdrawal from, or the Insolvency or Reorganization of, a Multiemployer
Plan; and in each case in clauses (i) through (v) above, such event or
condition, together with all other such events or conditions relating to a
Plan, if any, would be reasonably likely to subject the Company or any of
its Subsidiaries to any tax, penalty or other liabilities in the aggregate
material in relation to the business, assets, condition (financial or
otherwise) or results of operations of the Company and its Subsidiaries
taken as a whole; or

          (12) any Credit Document shall cease, for any reason, to be in
full force and effect or the Company or any of its subsidiaries shall so
assert in writing.

          The foregoing will constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or
involuntary or is effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body.

          The term "Bankruptcy Law" means Title 11, United States Code, or
any similar Federal or state law for the relief of debtors.  The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

          A  Default  under clauses (3) and (6) is not an Event of  Default
until  the Lender notifies the Company of the Default and the Company  does
not  cure  such  Default within the time specified after  receipt  of  such
notice.   Such notice must specify the Default, demand that it be  remedied
and state that such notice is a "Notice of Default".

          SECTION 8.02.  Acceleration.  If an Event of Default (other than
an Event of Default specified in Section 8.01(8) or (9) with respect to the
Company) occurs and is continuing, the Lender by notice to the Company may
declare the principal of and accrued interest on the Loan to be due and
payable. upon such a declaration, such principal and interest shall be due
and payable immediately.  If an Event of Default specified in Section
8.01(8) or (9) with respect to the Company (but not any Subsidiary) occurs,
the principal of and interest on the Loan Note shall ipso facto become and
be immediately due and payable without any declaration or other act on the
part of the Lender.  The Lender by notice to the Company may rescind an
acceleration and its consequences.  No such rescission

                                    49

<PAGE>

shall affect any subsequent Default or impair any right consequent thereto.

          SECTION 8.03. Default and Remedies.

          (a)  If an Event of Default occurs and is continuing, the Lender
shall have all of the remedies of a secured party under the Uniform
Commercial Code, including, without limitation, the right, to notify the
account debtors from which the Designated Payments are owing to pay
directly to the Lender the amount owing from such account debtors to the
Company in respect of the respective Designated Receivable.  In addition to
and not in derogation of any or all of the rights and remedies granted
hereunder to the Lender or otherwise available to the Lender under
applicable law, following such an Event of Default, the Lender shall have
the further right and power, at its sole option, to sell, or otherwise
dispose of, the Collateral (other than Collateral consisting of cash), or
any part thereof, at any one or more public or private sales as permitted
by applicable law, and for that purpose the Lender may take immediate and
exclusive possession of such Collateral, or any part thereof, to the extent
capable of possession.

          (b)  To the fullest extent permitted by law, the Company
irrevocably and expressly waives any right to receive any notice of sale or
notice of any other disposition of all or any part of the Collateral that
does not consist of cash, except that to the extent the Company may be
entitled by applicable law to any notice of sale or other disposition of
such Collateral, the Company agrees that if such notice is mailed, postage
prepaid, to the Company at the Company's address hereinafter specified not
less than five (5) days before the time of the sale or other disposition
contemplated therein, such notice shall conclusively be deemed commercially
reasonable and shall fully satisfy any requirement for giving of said
notice.  The Lender shall not be obligated to make any sale of Collateral
regardless of notice of sale having been given.  The Lender may adjourn any
public or private sale from time to time by announcement at the time and
place fixed therefor, and such sale may, without further notice, be made at
the time and place to which it was so adjourned.

          (c)  The proceeds realized upon any such disposition, after
deduction for the expenses of retaking, holding, preparing for sale,
selling or the like and reasonable attorneys' fees, legal expenses and
costs incurred by the Lender, shall be applied in accordance with Section
5.06.

          (d)  The remedies of the Lender hereunder are cumulative and the
exercise of any one or more of the remedies

                                    50

<PAGE>

provided for herein, or under the Uniform Commercial Code, shall not be
construed as a waiver of any other rights or remedies of the Lender so long
as any part of the Secured obligations remains unsatisfied or unperformed.
The making of this Agreement shall not waive or impair any other security
the Lender may have or hereafter acquire for the payment or performance of
the Secured Obligations, nor shall the making of any such additional
security waive or impair this Agreement; but the Lender may resort to any
security it may have in the order it may deem proper.

          SECTION 8.04.  Other Remedies.  If an Event of Default occurs and
is continuing, the Lender may pursue any available remedy to collect the
payment of principal of or interest on the Note or to enforce the
performance of any provision of the Note or this Agreement.

          The  Lender may maintain a proceeding even if it does not possess
the Note or does not produce it in the proceeding.  A delay or omission  by
the  Lender  in exercising any right or remedy accruing upon  an  Event  of
Default shall not impair the right or remedy or constitute a waiver  of  or
acquiescence in the Event of Default.  No remedy is exclusive of any  other
remedy.  All available remedies are cumulative.

          SECTION 8.05.  Waiver of Past Defaults.  The Lender by notice to
the Company may waive an existing Default and its consequences.  When a
Default is waived, it is deemed cured, but no such waiver shall extend to
any subsequent or other Default or impair any consequent right.

          SECTION 8.06.  Priorities. If the Lender collects any money or
property pursuant to this Article 8, it shall pay out the money or property
in the following order:

          FIRST: to itself in accordance with the priority set forth in
Section 2.08; and

          SECOND: to the extent of any excess, to the Company.

          SECTION 8.07. Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Agreement a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion
may assess reasonable costs, including reasonable attorneys' fees, against
any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant.

                                    51

<PAGE>

          SECTION 8.08. Waiver of Stay or Extension Laws.   The company (to
the extent it may lawfully do so) shall not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of
this Agreement; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law, and shall
not hinder, delay or impede the execution of any power herein granted to
the Lender, but shall suffer and permit the execution of every such power
as though no such law had been enacted.

                                 ARTICLE 9

                               Miscellaneous

          SECTION 9.01. Amendments and Waivers.  Except as otherwise
expressly set forth in this Agreement, no Credit Document nor any terms
thereof may be amended, supplemented, waived or modified except in
accordance with the provisions of this Section 9.01.

          SECTION 9.02. Notices.  All notices, requests and demands to or

provided that any notice, request or demand to or upon the Lender pursuant

          SECTION 9.03.  No Waiver; Cumulative Remedies.  No failure to
exercise and no delay in exercising, on the part of the Lender, any right,

or for recognition and enforcement of any judgment in respect thereof, to
the non-exclusive general jurisdiction of the courts of the State of New
York, the courts of the United States of

                                    55

<PAGE>

     America for the Southern District of New York, and appellate courts
from any thereof;

     (ii) consents that any such action or proceeding may be brought in

     (iii)     agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or
certified mail (or any substantially similar form of mail), postage
prepaid, to such party at its address set forth in Section 9.02; and

          SECTION 9.10.  Interest.  Each provision in this Agreement and
each other Credit Document is expressly limited so that in no event
whatsoever shall the amount paid, or otherwise agreed to be paid, by the
Company for the use, forbearance or detention of the money to be loaned
under this Agreement or any other Credit Document or otherwise (including
any sums paid as required by any covenant or obligation contained herein or
in any other Credit Document which is for the use, forbearance or detention
of such money) , exceed that amount of money which would cause the
effective rate of interest to exceed the highest lawful rate permitted by
applicable law (the "Highest Lawful Rate"), and all amounts owed under this
Agreement and each other Credit Document shall be held to be subject to
reduction to the effect that such amounts so paid or agreed to be paid
which are for the use, forbearance or detention of money under this
Agreement or such Credit Document shall in no event exceed that amount of
money which would cause the effective rate of interest to exceed the
Highest Lawful Rate.  Notwithstanding any provision in this Agreement or
any other Credit Document to the contrary, if the maturity of the Loan or
the obligations in respect of the other Credit Documents are accelerated
for any reason, or in the event of any prepayment of all or any portion of
the Loan or the obligations in respect of the other Credit Documents by the
Company or in any other event, earned interest on the Loan and such other
obligations of the Company may never exceed the Highest Lawful Rate, and
any unearned interest otherwise

                                    56

<PAGE>

payable on the Loan or the obligations in respect of the other Credit
Documents that is in excess of the Highest Lawful Rate shall be canceled
automatically as of the date of such acceleration or prepayment or other
such event and (if theretofore paid) shall, at the option of the holder of
the Loan or such other obligations, be either refunded to the Company or
credited on the principal of the Loan.  In determining whether or not the
interest paid or payable, under any specific contingency, exceeds the
Highest Lawful Rate, the Company and the Lender shall, to the maximum
extent permitted by applicable law, amortize, prorate, allocate and spread,
in equal parts during the period of the actual term of this Agreement, all
interest at any time contracted for, charged, received or reserved in
connection with this Agreement.

                                    57

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed and delivered in New York, New York by their proper and
