any of them in the proceeding. A delay or omission by the Trustee or any Securityholder 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 to the extent permitted by law.

involve the Trustee in personal liability unless the Trustee has indemnification reasonably satisfactory to it against any loss or expense caused by-its following such direction; and  provided,
further, that the Trustee may take any other action deemed proper by the Trustee that is not

(iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 8.2. Subject to compliance with this Section 8.2, the Company may
exercise its option under this paragraph (b) notwithstanding the prior exercise of its option under paragraph (c) below with respect to the Securities. 

    (c) Upon
the Company's exercise under paragraph (a) of the option applicable to this paragraph (c), the Company shall be released and discharged from its
obligations under any covenant contained in Article V and in Sections 4.4 through 4.8 and Sections 49 through 4.16 with respect to the outstanding Securities on and after the date the
conditions set forth below are satisfied (hereinafter, "covenant
defeasance"), and the Securities shall thereafter be deemed to be not "outstanding" for the purpose of any direction, waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the
outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly,
by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.1, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. 

    (d) The
following shall be the conditions to application of either paragraph (b) or paragraph (c) above to the outstanding Securities: 

     (i) the
Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 7.10 who
shall agree to comply with the 

34

 

provisions of this Section 8.2 applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the
benefit of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal of and interest in respect thereof
in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge and which shall be applied by the Trustee (or
other qualifying trustee) to pay and discharge principal of and interest on the outstanding-Securities on the Maturity Date of such principal or installment of principal or interest in accordance with
the terms of this Indenture and of such Securities; provided, however, that the Trustee (or other
qualifying trustee) shall have received an irrevocable written order from the Company instructing the Trustee (or other qualifying trustee) to apply such money or the proceeds of such U.S. Government
Obligations to said payments with respect to the Securities; 

    (ii) no
Default or Event of Default or event which with notice or lapse of time or both would become a Default or an Event of Default with respect to the Securities
shall have occurred and be continuing on the date of such deposit or, insofar as Sections 6.l(a)(vi) and (vii) are concerned, at any time during the period ending on the 91st day after
the date of such deposit (it being understood that this condition shall not be deemed satisfied until -the expiration -of such period); 

    (iii) such
legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a Default or Event of Default under, this Indenture or
any other material agreement or instrument to which the Company is a party or by which it is bound; 

    (iv) in
the case of an election under paragraph (b) above, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (x) the
Company has received from, or there has been published by, the Internal Revenue Service a ruling or (y) since the date of this Indenture, there has been a change in the applicable Federal
income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities will not recognize income, gain or loss for Federal
income tax purposes as a result of such legal defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such
legal defeasance had not occurred; 

    (v) in
the case of an election under paragraph (c) above, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of
the outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; 

    (vi) in
the case of an election under either paragraph (b) or (c) above, an Opinion of Counsel to the effect that, (x) the trust funds will not be
subject to any rights of any other holders of Indebtedness of the Company, and (y) after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable
Bankruptcy Law; provided, however, that if a court were to rule under any such law in any case or
proceeding that the trust funds remained property of the Company, no opinion needs to be given as to the effect of such laws on the trust funds except the following: (A) assuming such trust
funds remained in the Trustee's possession prior to such court ruling to the extent not paid to Holders of Securities, the Trustee will hold, for the benefit of the Holders of Securities, a valid and
enforceable security interest in such trust funds that is not avoidable in bankruptcy or otherwise, subject only to principles of equitable subordination., (B) the Holders of Securities' will
be entitled to receive adequate protection of their interests in such trust funds if such trust funds are used, and (C) no property, rights in 

35

 

property or other interests granted to the Trustee or the Holders of Securities in exchange for or with respect to any of such funds will be subject to any prior rights of any other Person, subject
only to prior Liens granted under Section 364 of Title 11 of the U.S. Bankruptcy Code (or any section of any other Bankruptcy Law having the same effect), but still subject to the foregoing
clause (B); 

   (vii) the
Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that (A) all conditions precedent provided
for relating to either the legal defeasance under paragraph (b) above or the covenant defeasance under paragraph (c) above, as the case may be, have been complied with and (B) if
any other Indebtedness of the Company shall then be outstanding or committed, such legal defeasance or covenant defeasance will not violate the provisions of the agreements or instruments evidencing
such Indebtedness; 

   (viii) the
Company shall have delivered to the Trustee an Officers' Certificate stating its intention to effect a defeasance pursuant to the provisions of this
Article VII at least three Business Days' prior to such defeasance; and 

    (ix) the
Company shall have paid or duly provided for payment under terms mutually satisfactory to the Company and the Trustee all amounts then due to the Trustee
pursuant to Section 7.7. 

    (e) All
money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of
this paragraph (e), the "Trustee") pursuant to paragraph (d) above in respect of the outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (other than the Company) as the Trustee may determine, to the Holders of such Securities
of all sums due and to become due thereon in respect of principal and interest, but such money need not be segregated from other funds except to the extent required by law. 

    The
Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to
paragraph (d) above or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding
Securities. 

    Anything
in this Section 8.2 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request, in writing, by the Company any
money or U.S. Government Obligations held by it as provided in paragraph (d) above which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent legal defeasance or covenant defeasance. 

    SECTION
8.3  Application of Trust Money.  

    The
Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Sections 8.1 and 8.2, and shall apply the deposited money and the money from U.S.
Government Obligations in accordance with this Indenture to the payment of principal of and interest on the Securities. 

36

 
    SECTION 8.4  Repayment to Company.  

    Subject
to Sections 7.7, 8.1 and 8.2, the Trustee shall promptly pay to the Company upon receipt -by the Trustee of an Officers' Certificate, any excess money, determined
in accordance with Sections 8.2(d)(i) and (e), held by it at any time. The Trustee and the Paying Agent shall pay to the Company upon receipt by the Trustee or the Paying Agent, as the case may
be, of an Officers' Certificate, any money held by it for the payment of principal or interest that remains unclaimed for two years; provided,  however,
that the Trustee and the Paying Agent before being required to make any payment may, but need not, at the expense of the Company cause to be
published once in a newspaper of general circulation in The City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified
therein, which shall be at least 30 days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the
Company Securityholders entitled to money must look solely to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of
the Trustee or Paying Agent with respect to such money shall thereupon cease. 

    SECTION
8.5  Reinstatement.  

    If
the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Indenture by reason of any legal proceeding or by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then and only then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had been made pursuant to this Indenture until such time as the Trustee is permitted to apply all such money or U.S. Government
Obligations in accordance with this Indenture; provided, however, that if the Company has made any
payment of interest on or. principal of any Securities because of the reinstatement of their obligations, the Company shall be subrogated to the rights of the holders of such Securities to receive
such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

    (c) to
comply with any requirements of the Commission under the TIA;

37

 

    SECTION
9.2  With Consent of Holders.  

    Subject
to Section 6.7 and the provisions of this Section 9.2, the Company and the Trustee may amend or supplement this Indenture or the Securities with the written
consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. Subject to Section 6.7 and the provisions of this Section 9.2, the Holders
of at least a majority in aggregate principal amount of the outstanding Securities may waive compliance by the Company with any provision of this Indenture or the Securities without notice to any
other Securityholder. However, without the consent of each
Securityholder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.4, may not: 

    (a) reduce
the amount of Securities the Holders of which must consent to an amendment, supplement or waiver or consent to take any action under any provision of this
Indenture or the Securities; 

    (b) reduce
the rate of, change the method of calculation of, or extend the time for, payment of interest on any Security;

    (e) change
the currency in which any Security or any premium or the accrued interest thereon is payable; 

    (f)  adversely

    (g) impair
the right to institute suit for the enforcement of any payment on or with respect to the Securities; or 

    (h) modify
this Section 9.2 or Section 6.4. 

    It
shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment, supplement or. waiver, but it shall be
sufficient if such consent - approves the substance thereof. 

    After
an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company shall mail to the Holders affected thereby a. notice briefly describing the
amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement
or waiver. 

    SECTION
9.3  Compliance with Trust Indenture Act.  

    Every
amendment to or supplement of this Indenture or the Securities shall comply with the TIA as then in effect. 

    SECTION
9.4  Revocation and Effect of Consents.  

    Until
an amendment or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and -every subsequent Holder of that Security or portion of that
Security that -evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of a Security. Such revocation shall be effective only if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver
becomes effective. 

38

 

Notwithstanding the above, nothing in this paragraph shall impair the right of any Securityholder under § 316(b) of the TIA. 

    The
Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record
date is fixed, then notwithstanding the second and third sentences of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and
only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record
date. Such consent shall be effective only for actions taken within 90 days after such record date. 

    After
an amendment, supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (a) through (h) of
Section 9.2; if it makes such a change, the amendment, supplement or waiver shall bind every subsequent Holder of a Security or portion of a Security that evidences the same debt as the
consenting Holder's Security. 

    SECTION
9.5  Notation on or Exchange of Securities.  

    If
an amendment, supplement or waiver changes the terms of a Security, the Trustee shall (in accordance with the specific written direction of the Company) request the Holder of the
Security to deliver it to the Trustee. The Trustee shall (in accordance with the specific written direction of the Company) place an appropriate notation on the Security about the changed terms and
return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that
reflects the changed terms. Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver. 

    SECTION
9.6  Trustee To Sign Amendments, Etc.  

    The
Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article IX if the amendment, supplement or waiver does not adversely affect the rights,
duties or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing any amendment, supplement or waiver, the Trustee shall be entitled to receive, if requested, an
indemnity satisfactory to it in its sole discretion and to receive, and shall be fully protected in relying upon, an Officers' Certificate and/or an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article IX is authorized or permitted by this Indenture. The Company may not sign an amendment until its Board of Directors
approves it.

pay, until the principal hereof is paid or made available for-payment, interest on the principal amount set forth on the front of this Senior Note at a rate of 8 7/8% per annum. Interest
on -the Senior Notes will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from and including February 14, 1996 to
but excluding the date on which interest is paid. Interest shall be payable in arrears on February 15 and August 15, commencing August 15, 1996. Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months. The Company shall pay interest on overdue principal and on overdue interest (to the full extent permitted by law) at
a rate of 8 7/8% per annum. 

    2.  Method of Payment.  The Company will pay interest on the Senior Notes (except defaulted interest) to
the Persons who are the registered Holders of Senior Notes at the close of business on the February 1 or August 1 next preceding the interest payment -date. Holders must
surrender Senior Notes to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Interest may be paid by wire transfer or check mailed to the person entitled thereto as shown on the Registrar for the Senior Notes. 

    3.  Paying Agent and Registrar.  Initially, IBJ Schroder Bank & Trust Company (the "Trustee") will
act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar without notice to Securityholders. Neither the Company nor any of its Subsidiaries may
act as Paying Agent, Registrar or co-1~egistrar. 

    4.  Indenture.  The Company issued the Senior Notes under an Indenture, dated as of February 14,
1996 (the "Indenture") between the Company and the Trustee. This Senior Note is one of an issue of Senior Notes of the Company issued, or to be issued, under the Indenture. The terms of the Senior
Notes include those stated in this Note, the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code
§§ 77aaa-77bbbb), as amended from time to time. The Senior Notes are subject to all such-terms, and Holders are referred to the Indenture and
such Act for a statement of them. Capitalized and certain other terms used herein and not otherwise defined have the meanings set forth in the Indenture. The Senior Notes are unsecured obligations of
the Company limited in aggregate principal amount to $100,000,000. 

    The
Indenture limits, among other things, the incurrence of Indebtedness by the Company-and its Subsidiaries; the creation of Liens by the Company and its Subsidiaries;
purchases, redemptions, and other acquisitions or retirements of Capital: Stock of the Company and its Subsidiaries; transactions by the Company>and its Subsidiaries with their respective Affiliates;
and the ability of the Company or
any of its Subsidiaries to merge with or into another entity. The limitations are -subject to a. number of important qualifications and exceptions. The Company must report to the Trustee quarterly on
compliance with the limitations contained in the Indenture. 

    5.  Offers To Purchase.  Sections 4.12 and 4.15 of the Indenture provide that after an Asset Sale or upon
the occurrence of a Change of Control, and subject to further limitations contained therein, the Company shall make an offer to purchase Senior Notes in accordance with the -procedures set forth in
the Indenture. 

    6.  Denominations, Transfer, Exchange.  The Senior Notes are issued in registered form without coupons in
denominations of $1,000 and integral multiples of $1,000. A Holder may transfer or exchange Senior Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay to it any taxes and fees required by law or permitted by the Indenture. 

    7.  Persons Deemed Owners.  The registered Holder of a Senior Note may be treated as the owner of it for
all purposes. 

    8.  Unclaimed Money.  If money for the payment of principal or interest remains unclaimed for two years,
the Trustee or Paying Agent will pay the money back to the Company at its request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an
"abandoned property" law designates another Person. 

    9.  Amendment, Supplement, Waiver.  The Company and the Trustee may, without the consent of the Holders
of any outstanding Senior-Notes, amend, waive or supplement the Indenture or the Senior Notes for certain specified purposes, including, among other things, curing ambiguities, defects or
inconsistencies, maintaining the qualification of the Indenture under the Trust Indenture Act of 1939, as amended, or making any change that does not adversely affect the rights of any Holder. Other
amendments and modifications of the Indenture or the Senior Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal
amount of the-outstanding Senior Notes, subject to certain exceptions requiring the consent of the Holders of the particular Senior Notes to be affected. 

    10.  Successor Corporation.  When a successor corporation assumes all the obligations of its predecessor
under the Senior Notes and the Indenture and the transaction complies with the terms of Article V of the Indenture, the predecessor corporation will be released from those obligations. 

    11.  Defaults and Remedies.  Events of Default are set forth in the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Section 6.1(a) (vi) or (vii) of the Indenture) occurs with respect to. the
Company and is continuing, then the Holders of not less than 25% in aggregate principal :amount of the outstanding Senior Notes may, and the Trustee upon the written request of the Holders of not less
than 25% in aggregate principal amount of the outstanding Senior Notes shall, declare the principal of and interest on all of the Senior Notes to be due and payable immediately. If an Event of Default
specified in Section 6.l(a)(vi) or (vii) of the Indenture occurs with respect to the Company and is continuing, the principal of and interest on all of the Senior Notes shall ipso
facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Senior Notes except as
provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Senior Notes. Subject to certain limitations, Holders of a majority in principal
amount of the then outstanding Senior Notes may direct the Trustee in writing in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a
default in payment of principal or interest) if it determines that withholding notice is in their interests. 

    12.  Trustee Dealings with Company.  The Trustee, in its individual or any other capacity, may make loans
to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not Trustee. 

    13.  No Recourse Against Others.  A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the Senior Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or-their
creation. Each Holder by accepting a Senior Note waives- and releases all such liability. The waiver and release are part of the consideration for the issue of the Senior Notes. 

    14.  Discharge.  The Company's obligations pursuant to the Indenture will be discharged, except for
obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Senior Notes or upon the irrevocable deposit with the Trustee of money or U.S.
Government Obligations sufficient to pay when due principal of and interest on the Senior Notes to maturity. 

    15.  Authentication.  This Senior Note shall not be valid until the Trustee signs the certificate of
authentication on the front of this Senior Note. 

    16.  Abbreviations.  Customary abbreviations may be used in the name of a Holder or an assignee, such as:
TEN COM ( = tenants in common), TEN ENT ( = tenants by the entireties), JT TEN ( = joint tenants with right of survivorship and not as tenants in common), CUST ( = Custodian), and U/G/M/A ( = Uniform
Gifts to Minors Act). 

    The
Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:

  TERM LOAN AND SECURITY AGREEMENT    
  

    This THIRD AMENDMENT TO REVOLVING CREDIT, TERM LOAN AND SECURITY AGREEMENT (this "Amendment") is made and
entered into this 26th day of June, 2001 and is effective as of April 1, 2001, by and among AAF-MCQUAY INC., a Delaware
corporation "Borrower"); the various financial institutions listed on the signature pages hereof and their respective successors and permitted assigns which become "Lenders"; and  PNC BANK, NATIONAL ASSOCIATION, a national association ("PNC"), as collateral and administrative agent for Lenders (PNC, together with its successors in
such capacity, the "Agent"). 

Recitals:  

    Agent, Lenders and Borrower are parties to a certain Revolving Credit, Term Loan and Security Agreement dated September 30, 1999 (as at any time
amended, the "Credit Agreement") pursuant to which Lenders have made certain revolving credit and term loans to Borrower. 

    The
parties desire to amend the Credit Agreement as hereinafter set forth. 

    NOW,
THEREFORE, for TEN DOLLARS ($10.00) in hand paid and other good and valuable consideration, the receipt and sufficiency of which are hereby severally acknowledged, the parties
hereto, intending to be legally bound hereby, agree as follows: 

    1.  Definitions.  All capitalized terms used in this Amendment, unless otherwise
defined herein, shall have the meaning ascribed to such terms in the Credit Agreement. 

    2.  Amendments to Credit Agreement.  The Credit Agreement is hereby amended as
follows: 

	a.
	By
deleting the definition of "Applicable Margin" from Section 1.2 in its entirety and inserting the following in lieu thereof: 

"Applicable
Margin" shall mean a percentage equal to 1.75% with respect to Revolving Advances that are Eurodollar Rate Loans, 0.00% with respect to Revolving Advances that are Domestic Rate Loans,
2.00% with respect to any portion of the Term Loan made or outstanding as Eurodollar Rate Loans, and 0.00% with respect to any portion of the Term Loan made or outstanding as Domestic Rate Loans;
provided that, commencing July 1, 2001, 

 

the Applicable Margin shall be increased or (if no Default or Event of Default exists) decreased, based on the Fixed Charge Coverage Ratio, as follows: 

	Fixed

Charge Coverage Ratio
	 	Revolving Advances

that are made or

outstanding as

Domestic Rate Loans
	 	Applicable Margin For

	Greater than or equal to 1.10:1.00 and less than 1.25:1.00	 	0.00	%	2.25	%	0.25	%	2.50	%
	Greater than or equal to 1.25:1.00 and less than 1.50:1.00	 	0.00	%	2.00	%	0.00	%	2.25	%
	Greater than or equal to 1.50:1.00 and less than 1.75:1.00	 	0.00	%	1.75	%	0.00	%	2.00	%
	Greater than or equal to 1.75:1.00	 	0.00	%	1.50	%	0.00	%	1.75	%

The
Applicable Margin shall be subject to reduction or increase, as applicable and as set forth in the table above, on a quarterly basis according to the performance of Borrower as measured by the
Fixed Charge Coverage Ratio for the immediately preceding four (4) Fiscal Quarters of Borrower. Except as set forth in the last sentence hereof, any such increase or reduction in the Applicable
Margin provided for herein shall be effective three (3) Business Days after receipt by Agent of the applicable financial statements and corresponding Compliance Certificate. If the financial
statements and the Compliance Certificate of Borrower setting forth the Fixed Charge Coverage Ratio are not received by Agent by the date required pursuant to Section 9.8 hereof, the Applicable
Margin shall be determined as if the
Fixed Charge Coverage Ratio was greater than 1.00:1.00 and less than 1.10:1.00 until such time as such financial statements and Compliance Certificate are received and any Event of Default resulting
from a failure timely to deliver such financial statements or Compliance Certificate is waived in writing by Agent and Lenders; provided,  however, that
nothing herein shall be deemed to prevent Agent and Lenders from charging interest at the Default Rate for so long as an Event of Default
exists. For the final Fiscal Quarter of any Fiscal Year of Borrower, Borrower may provide the unaudited financial statements of Borrower, subject only to year-end adjustments, for the
purpose of determining the Applicable Margin; provided, however, that if, upon delivery of the annual
audited financial statements required to be submitted by Borrower to Agent pursuant to Section 9.7 hereof, Borrower has not met the criteria for reduction of the Applicable Margin pursuant to
the terms hereinabove for the final Fiscal Quarter of the Fiscal Year of Borrower then ended, then (a) such Applicable Margin reduction shall be terminated and, effective on the first day of
the month following receipt by Agent of such audited financial statements, the Applicable Margin shall be the Applicable Margin that would have been in effect if such reduction had not been
implemented based upon the unaudited financial statements of Borrower for the final Fiscal Quarter of the Fiscal Year of Borrower then ended, and (b) Borrower shall pay to Agent, for the
benefit of the Lenders, on the first day of the month following receipt by Agent of such audited financial statements, an amount equal to the difference between the amount of interest that would have
been paid on the principal amount of the Obligations using the Applicable Margin determined based upon such audited financial statements and the amount of interest actually paid during 

2

 

the period in which the reduction of the Applicable Margin was in effect based upon the unaudited financial statements for the final Fiscal Quarter of the Fiscal Year of Borrower then ended. 

	b.
	By
deleting the Section 6.7 in its entirety and inserting the following in lieu thereof: 

    6.7  Consolidated Total Assets.  Maintain, at all times, Consolidated Total
Assets of at least $600,000,000. 

	c.
	By
deleting the Section 13.1 in its entirety and inserting the following in lieu thereof: 

    13.1  Term.  This Agreement shall become effective on the date hereof and shall
continue in full force and effect until February 1, 2003 (the "Term"), unless sooner terminated as herein provided. 

    3.  Public Notes.  Notwithstanding the provisions of the Credit Agreement
prohibiting the Borrower from repurchasing any more than $20,000,000 of outstanding Public Notes, Borrower has requested that Agent and Lenders consent to Borrower's repurchase of up to an aggregate
principal amount of $35,000,000 of outstanding Public Notes. Agent and Lenders hereby consent to Borrower's repurchase of up to an aggregate principal amount of $35,000,000 of outstanding Public
Notes, upon satisfaction of each of the following conditions as of the time of each such repurchase: (a) Lenders have not
accelerated the maturity or demanded payment of the Obligations under the Credit Agreement, whether or not Borrower has received notice of such acceleration or demand for payment, (b) each such
repurchase is at no time violative of the Indenture, the Public Notes, or any of the other agreements, instruments and documents executed in respect of the transactions contemplated by the Indenture,
(c) the funds used to repurchase the Public Notes (i) do not constitute proceeds of "Indebtedness" as such term is defined in the Indenture, (ii) are not proceeds of Advances made
by Lenders under the Credit Agreement, and (iii) are received by Borrower either (W) as dividends from one or more Subsidiaries, (X) as repayments of Permitted Investments
previously made by Borrower in one or more Subsidiaries, (Y) as the proceeds of loans to Borrower from one or more Subsidiaries provided that such loans are permitted under both the Credit
Agreement and the Indenture, or (Z) as the proceeds from the sale of Borrower's Singapore Subsidiary, and (d) Borrower shall give Agent notice at least three (3) Business Days in
advance of each proposed repurchase of Public Notes, with such notice specifying the date of the proposed repurchase, the principal amount of Public Notes being repurchased, and the price to be paid
by Borrower to repurchase such Public Notes.

Credit Agreement are true and correct on and as of the date hereof.

    12.  Counterparts; Telecopied Signatures.  This Amendment may be executed in any
number of counterparts and by different parties to this Amendment on separate counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute one

and Lenders shall reasonably request from time to time in connection herewith to evidence or give effect to the amendments set forth herein or any of the transactions contemplated hereby.
