         Item 1.  Changes in Control of the Registrant

         The Company is a wholly owned subsidiary of AT Holdings Corporation
("Holdings") which owns 3,000 shares, or 100% of the Company's outstanding
common stock, par value of $.01 per share. On December 17, 1998, Holdings and AT
Holdings, LLC ("AT LLC"), Holdings' majority stockholder, entered into a Stock
Purchase Agreement whereby Holdings would repurchase (the "Stock Repurchase")
639,510 shares of Holdings' common stock held by AT LLC for a purchase price of
$79,590,000 on January 4, 1999. The purchase price was financed on December 17,
1998 through the placement of $55 million in debt securities of the Company by
Chase Securities Inc. and the issuance by Holdings of 30,000 shares of its
Cumulative Exchangeable Redeemable Preferred Stock to Chase Venture Capital
Associates, L.P. ("CVCA"). The Stock Repurchase was consummated on January 4,
1999.

         After giving effect to the Stock Repurchase, the Company's management
and its Employee Stock Ownership Plan (the "ESOP") hold approximately 71.5% of
the outstanding shares of Holdings' common stock. AT LLC and YC International,
Inc., which are each controlled by Mr. Masashi Yamada, hold approximately 12.2%
of the outstanding shares of Holdings' common stock. The remaining 16.3% of the
outstanding shares of Holdings' common stock is held by Sunhorizon
International, Inc.

         On December 17, 1998, all of the holders of Holdings common and
preferred stock, with the exception of the ESOP, entered into the 1998 AT
Holdings Corporation Stockholders Agreement (the "1998 Agreement"). The 1998
Agreement terminates and replaces the 1994 AT Holdings Corporation Stockholders
Agreement, as amended, which is filed as Exhibits 10.12, 10.13 and 10.14 to the
Company's registration statement on Form S-1, File No. 333-38223. The 1998
Agreement provides (i) management the right to nominate a majority of the Board
of Directors of Holdings, (ii) Mr. Yamada the right to nominate a minority of
the Holdings' Board and (iii) CVCA the right to designate one non-voting
representative to attend all Board and Board committee meetings. The Company is
not a party to the 1998 Agreement.

                          FIRST SUPPLEMENTAL INDENTURE


                  THIS FIRST SUPPLEMENTAL INDENTURE (this "SUPPLEMENTAL

("AFTERMARKET") and J.C. CARTER COMPANY, INC., a California corporation
("CARTER," and together with HBP, OEM and Aftermarket, the "SUBSIDIARY
GUARANTORS") and HARRIS TRUST AND SAVINGS BANK, as trustee (the "TRUSTEE").

                                    RECITALS:

         A. The Company, the Subsidiary Guarantors and the Trustee have entered
into an Indenture dated as of September 26, 1997 (the "INDENTURE").

         B. Pursuant to the Indenture, the Company issued and the Trustee
authenticated and delivered an aggregate principal amount of $140,000,000 of the
Company's 85/8% Senior Subordinated Notes due 2007.

         C. Section 9.02 of the Indenture provides, among other things, that
with the written consent of Securityholders holding not less than a majority in
principal amount of the Securities then outstanding (the "REQUISITE CONSENTS"),
the Company may from time to time amend or supplement the Indenture, subject to
certain exceptions specified in Section 9.02 of the Indenture.

         D. On December 7, 1998, the Company mailed a Consent Solicitation
Statement to each Holder of record as of December 7, 1998. The Company has
obtained the Requisite Consents.

         E. This Supplemental Indenture has been duly authorized by all
necessary corporate action on the part of the Company.

         F. The Company has delivered, or caused to be delivered, to the
Trustee, an Officer's Certificate and an Opinion of Counsel meeting the
requirements of Section 9.06 of the Indenture and stating that all conditions
precedent and covenants, if any, provided for in the Indenture relating to this
Supplemental Indenture have been satisfied.

         NOW THEREFORE, each party agrees for the benefit of the other party and
for the equal and ratable benefit of all Securityholders, as follows:

                                   AGREEMENT:

         SECTION 1. DEFINITIONS. Capitalized terms used in this Supplemental
Indenture and not otherwise defined herein have the meanings given them in the
Indenture.



<PAGE>   2






         SECTION 2. AMENDMENT TO SECTION 4.04 OF THE INDENTURE. At the
Effectiveness Time (as defined below), Section 4.04 of the Indenture will hereby
be amended by the addition of a new clause (b)(vi) thereto, reading as set forth
below:

         (vi)     the payment by the Company of a dividend or distribution on
                  its Capital Stock to Parent, or the making of a loan by the
                  Company to Parent, in an amount not to exceed $50,000,000, the
                  proceeds of which will be used, together with the proceeds
                  from the issuance by Parent of its Cumulative Exchangeable
                  Redeemable Preferred Stock, to finance the payment of the
                  purchase price, not to exceed $80,000,000, for 639,510 shares
                  of Capital Stock of Parent held by AT Holdings, LLC; provided,
                  however, that such dividend, distribution or loan shall be
                  excluded from the calculation of the amount of Restricted
                  Payments.

         As used herein, "Effectiveness Time" means the latest of:

                  (a)      the consummation of the issuance by Parent of
                           Cumulative Exchangeable Preferred Stock to Chase
                           Venture Capital Associates, L.P. having a liquidation
                           preference of $30.0 million;

                  (b)      the waiver by the parties to the Stockholders
                           Agreement of all of their rights provided under such
                           agreement;

                  (c)      the consummation of the repurchase by Parent of
                           639,510 shares of its Common Stock from AT Holdings,
                           LLC;

                  (d)      the effectiveness of an amendment to the Credit
                           Agreement to permit the transactions described in (a)
                           - (c) of this Section; and

                  (e)      the termination of the Stockholders Agreement and the
                           execution of a new stockholders agreement with
                           respect to Parent.

         SECTION 3.  MISCELLANEOUS.

         3.1 EFFECT OF SUPPLEMENTAL INDENTURE. Upon the execution and delivery
of this Supplemental Indenture by the Company, the Subsidiary Guarantors and the
Trustee, the Indenture shall be supplemented in accordance herewith, and this
Supplemental Indenture shall form a part of the Indenture for all purposes, and
every Securityholder holding Securities that have been heretofore or hereafter
authenticated and delivered under the Indenture shall be bound thereby. Except
as supplemented hereby, all provisions of the Indenture shall remain in full
force and effect.

         3.2 INDENTURE AND SUPPLEMENTAL INDENTURE CONSTRUED TOGETHER. This
Supplemental Indenture is an indenture supplemental to and in implementation of
the Indenture, and the Indenture and this Supplemental Indenture shall

         3.4 CONFLICT WITH TRUST INDENTURE ACT. If any provision of this
Supplemental Indenture limits, qualifies or conflicts with any provision of the
Trust Indenture Act of 1939, as amended (the "ACT"), that is required under such
Act to be part of and govern any provision of this Supplemental Indenture, the
provision of such Act shall control. If any provision of this Supplemental
Indenture modifies or excludes any provision of the Act that may be so modified
or excluded, the provisions of the Act shall be deemed to apply to the Indenture
as so modified or to be excluded by this Supplemental Indenture, as the case may
be.

         3.5 SEPARABILITY CLAUSE. In case any provision of this Supplemental
Indenture shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         3.6 EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

         3.7 BENEFITS OF SUPPLEMENTAL INDENTURE. Nothing in this Supplemental
Indenture, the Indenture, or the Securities, express or implied, shall give to
any Person, other than the parties hereto and thereto and their successors
hereunder and thereunder, and the Securityholders, any benefit of any legal or
equitable right, remedy or claim under the Indenture, the Supplemental Indenture
or the Securities.

         3.8 SUCCESSORS AND ASSIGNS. All covenants and agreements in this
Supplemental Indenture by the Company shall bind its successors and assigns,
whether so expressed or not.

         3.9 NEW YORK LAW TO GOVERN. THIS SUPPLEMENTAL INDENTURE SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE
EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY.

         3.10 COUNTERPARTS. This Supplemental Indenture may be executed in
counterparts, each of which shall be an original, but such counterparts shall
together constitute one and the same instrument.

         3.11 TERMINATION. If the Effectiveness Time does not occur before
January 15, 1999, this Supplemental Indenture shall not become effective and the
Indenture shall remain in full force and effect unmodified by this Supplemental
Indenture.

     maximum liquidation value of such Preferred Stock or (ii) the maximum
     mandatory redemption or mandatory repurchase price with respect to such
     Preferred Stock, whichever is greater.

                                 THE SECURITIES

         SECTION 2.01. FORM AND DATING. Provisions relating to the Initial
Securities, the Private Exchange Securities and the Exchange Securities are set
forth in the Appendix, which is hereby incorporated in and expressly made a part

exchange rule, agreements to which the Company or the Subsidiary Guarantors are
subject (PROVIDED that any such notation, legend or endorsement is in a form

thereof.

                                                                              20

         SECTION 2.02. EXECUTION AND AUTHENTICATION. One or more Officers of the
Company shall sign the Securities by manual or facsimile signature.

         If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

         A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

         The Trustee shall authenticate and make available for delivery
Securities as set forth in the Appendix.

         The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Securities. Any such appointment shall be
evidenced by an instrument signed by a Trust Officer, a copy of which shall be
furnished to the Company. Unless limited by the terms of such appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as any
Registrar, Paying Agent or agent for service of notices and demands.

         SECTION 2.03. REGISTRAR AND PAYING AGENT. The Company shall maintain an
office or agency where Securities may be presented for registration of transfer
or for exchange (the "Registrar") and an office or agency where Securities may
be presented for payment (the "Paying Agent"). The Registrar shall keep a
register of the Securities and of their transfer and exchange. The Company may
have one or more coregistrars and one or more additional paying agents. The term
"Paying Agent" includes any additional paying agents and the term "Registrar"
includes any co-registrars. The Company initially appoints the Trustee as (i)
Registrar and Paying Agent in connection with the Securities and (ii) the
Securities Custodian (as defined in the Appendix) with respect to the Global
Securities (as defined in the Appendix).

         The Company shall enter into an appropriate agency agreement with any
Registrar or Paying Agent not a party to this Indenture, which shall incorporate
the terms of the TIA. The agreement shall implement the provisions of this
Indenture that relate to such agent. The Company shall notify the Trustee of the
name and address of any such agent. If the Company fails to maintain a Registrar
or Paying Agent, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 7.07. Either the Company
or any domestically organized Wholly Owned Subsidiary may act as Paying Agent or
Registrar.

         The Company may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Trustee, PROVIDED, HOWEVER,
that no such removal shall become effective until (1) acceptance of an
appointment by a successor as evidenced by an appropriate agreement entered into
by the Company and such successor Registrar or Paying Agent, as the case may be,
and delivered to the Trustee or (2) notification to the Trustee that the Trustee
shall serve as Registrar or Paying Agent until the appointment of a successor in
accordance with clause (1) above. The Registrar or Paying Agent may resign at
any time upon written notice; PROVIDED,


<PAGE>   27


                                                                              21

HOWEVER, that the Trustee may resign as Paying Agent or Registrar only if the
Trustee also resigns as Trustee in accordance with Section 7.08.

         SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. Prior to each due
date of the principal and interest on any Security, the Company shall deposit
with the Paying Agent (or if the Company or a permitted Wholly Owned Subsidiary
is acting as Paying Agent, segregate and hold in trust for the benefit of the
Persons entitled thereto) a sum sufficient to pay such principal and interest
when so becoming due. The Company shall require each Paying Agent (other than
the Trustee) to agree in writing that the Paying Agent shall hold in trust for
the benefit of Securityholders or the Trustee all money held by the Paying Agent
for the payment of principal of or interest on the Securities and shall notify
the Trustee of any default by the Company in making any such payment. If the
Company or a permitted Wholly Owned Subsidiary acts as Paying Agent, it shall
segregate the money held by it as Paying Agent and hold it as a separate trust
fund. The Company at any time may require a Paying Agent to pay all money held
by it to the Trustee and to account for any funds disbursed by the Paying Agent.
Upon complying with this Section, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

         SECTION 2.05. SECURITYHOLDER LISTS. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish, or cause the Registrar to furnish, to the
Trustee, in writing at least five Business Days before each interest payment
date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Securityholders.

         SECTION 2.06. TRANSFER AND EXCHANGE. The Securities shall be issued in
registered form and shall be transferable only upon the surrender of a Security
for registration of transfer and in compliance with the Appendix. When a
Security is presented to the Registrar with a request to register a transfer,
the Registrar shall register the transfer as requested if the requirements of
Section 8-401(a)(l) of the Uniform Commercial Code are met. When Securities are
presented to the Registrar with a request to exchange them for an equal
principal amount of Securities of other denominations, the Registrar shall make
the exchange as requested if the same requirements are met. To permit
registration of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Securities at the Registrar's request. The Company
may require payment of a sum sufficient to pay all taxes, assessments or other
governmental charges in connection with any transfer or exchange pursuant to
this Section. The Company shall not be required to make, and the Registrar need
not register, transfers or exchanges of Securities selected for redemption
(except, in the case of Securities to be redeemed in part, the portion thereof
not to be redeemed) or transfers or exchanges of any Securities for a period of
15 days before a selection of Securities to be redeemed.

         Prior to the due presentation for registration of transfer of any
Security, the Company, the Subsidiary Guarantors, the Trustee, the Paying Agent
and the Registrar may deem and treat the Person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving
payment of principal of and accrued and unpaid interest (if any) on such
Security and for all other purposes whatsoever, whether or not such Security is
overdue, and none of the Company, any Subsidiary


<PAGE>   28


                                                                              22

Guarantor, the Trustee, the Paying Agent or the Registrar shall be affected by
notice to the contrary.

         Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected only through a book-entry system maintained by (i) the Holder of
such Global Security (or its agent) or (ii) any Holder of a beneficial interest
in such Global Security, and that ownership of a beneficial interest in such
Global Security shall be required to be reflected in a book entry.

         All Securities issued upon any transfer or exchange pursuant to the
terms of this Indenture will evidence the same debt and will be entitled to the
same benefits under this Indenture as the Securities surrendered upon such
transfer or exchange.

         SECTION 2.07. REPLACEMENT SECURITIES. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met, such that the Holder (i)
satisfies the Company or the Trustee within a reasonable time after he has
notice of such loss, destruction or wrongful taking and the Registrar does not
register a transfer prior to receiving such notification, (ii) makes such
request to the Company or the Trustee prior to the Security being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code
(a "protected purchaser") and (iii) satisfies any other reasonable requirements
of the Trustee. If required by the Trustee or the Company, such Holder shall
furnish an indemnity bond sufficient in the judgment of the Trustee to protect
the Company, the Trustee, the Paying Agent, and the Registrar from any loss that
any of them may suffer if a Security is replaced. The Company and the Trustee
may charge the Holder for their expenses in replacing a Security. In the event
any such mutilated, lost, destroyed or wrongfully taken Security has become or
is about to become due and payable, the Company in its discretion may pay such
Security instead of issuing a new Security in replacement thereof.

         Every replacement Security is an additional obligation of the Company.

         The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

         SECTION 2.08. OUTSTANDING SECURITIES. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancelation and those described in this Section
as not outstanding. Subject to Section 13.06, a Security does not cease to be
outstanding because the Company or its Affiliate holds the Security.

         If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a protected purchaser.

         If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal

                                                                              23

and interest payable on that date with respect to the Securities (or portions
thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is
not prohibited from paying such money to the Securityholders on that date
pursuant to the terms of this Indenture, then on and after that date such
Securities (or portions thereof) cease to be outstanding and interest on them
ceases to accrue.

         SECTION 2.09. TEMPORARY SECURITIES. In the event that Definitive
Securities (as defined in the Appendix) are to be issued under the terms of this
Indenture, until such Definitive Securities are ready for delivery, the Company
may prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of Definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate Definitive Securities and deliver them in exchange for temporary
Securities upon surrender of such temporary Securities at the office or agency
of the Company, without charge to the Holder.

         SECTION 2.10. CANCELATION. The Company at any time may deliver
Securities to the Trustee for cancelation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and deliver canceled Securities to the Company pursuant to written
direction by an Officer. The Company may not issue new Securities to replace
Securities they have redeemed, paid or delivered to the Trustee for cancelation.
The Trustee shall not authenticate Securities in place of canceled Securities
other than pursuant to the terms of this Indenture.

         SECTION 2.11. DEFAULTED INTEREST. If the Company defaults in a payment
of interest on the Securities, the Company shall pay the defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the Persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail or cause to be
mailed to each Securityholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.

         SECTION 2.12. CUSIP NUMBERS. The Company in issuing the Securities may
use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders; PROVIDED,
HOWEVER, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers.

Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date and the principal amount of Securities
to be redeemed.

         The Company shall give each notice to the Trustee provided for in this
Section at least 60 days before the redemption date unless the Trustee consents
to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein. If fewer than all the
Securities are to be redeemed, the record date relating to such redemption shall
be selected by the Company and given to the Trustee, which record date shall be
not fewer than 15 days after the date of notice to the Trustee. Any such notice
may be canceled at any time prior to notice of such redemption being mailed to
any Holder and shall thereby be void and of no effect.

         SECTION 3.02. SELECTION OF SECURITIES TO BE REDEEMED. If fewer than all
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed pro rata or by lot or by a method that complies with applicable legal
and securities exchange requirements, if any, and that the Trustee in its sole
discretion considers fair and appropriate and in accordance with methods
generally used at the time of selection by fiduciaries in similar circumstances.
The Trustee shall make the selection from outstanding Securities not previously
called for redemption. The Trustee may select for redemption portions of the
principal of Securities that have denominations larger than $1,000. Securities
and portions of them the Trustee selects shall be in amounts of $1,000 or a
whole multiple of $1,000. Provisions of this Indenture that apply to Securities
called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly of the Securities or
portions of Securities to be redeemed.

         SECTION 3.03. NOTICE OF REDEMPTION. The Company shall deliver a notice
of redemption to each Holder of Securities to be redeemed (a) in the case of an
optional redemption pursuant to paragraph 5 of the Securities, by first-class
mail at least 30 but not more than 60 days before the redemption date or (b) in
the case of a mandatory redemption pursuant to paragraph 6 of the Securities, by
overnight mail or facsimile not less than one day before the redemption date.

          The notice shall identify the Securities to be redeemed and shall
state:

          (1) the redemption date;

          (2) the redemption price;

          (3) the name and address of the Paying Agent;

          (4) that Securities called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

          (5) in the case of an optional redemption pursuant to paragraph 5 of
     the Securities if fewer than all the outstanding Securities are to be
     redeemed, the certificate numbers and principal amounts of the particular
     Securities to be redeemed;

          (6) that, unless the Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Securities (or portion thereof)
     called for redemption ceases to accrue on and after the redemption date;

          (7) the paragraph of the Securities pursuant to which the Securities
     called for redemption are being redeemed;

          (8) the CUSIP number, if any, printed on the Securities being
     redeemed; and

          (9) that no representation is made as to the correctness or accuracy
     of the CUSIP number, if any, listed in such notice or printed on the
     Securities.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section.

         SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION. Once notice of redemption
is mailed or transmitted, as applicable, Securities called for redemption become
due and payable on the redemption date and at the redemption price stated in the
notice. Upon surrender to the Paying Agent, such Securities shall be paid at the
redemption price stated in the notice, plus accrued interest (if any) to the
redemption date, PROVIDED that if the redemption date is after a regular record
date and on or prior to the interest payment date, the accrued interest shall be
payable to the Securityholder of the redeemed Securities registered on the
relevant record date. Failure to give notice or any defect in the notice to any
Holder shall not affect the validity of the notice to any other Holder.

         SECTION 3.05. DEPOSIT OF REDEMPTION PRICE. Prior to 10:00 a.m. on the
redemption date, the Company shall deposit or cause to be deposited with the
Paying Agent (or, if the Company or a permitted Wholly Owned Subsidiary is the
Paying Agent, shall segregate and hold in trust) money sufficient to pay the
redemption price of and accrued interest (if any) on all Securities to be
redeemed on that date other than Securities or portions of Securities called for
redemption that have been delivered by the Company to the Trustee for
cancelation.

         SECTION 3.06. SECURITIES REDEEMED IN PART. Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate for the Holder (at the Company's expense) a new Security equal in
principal amount to the unredeemed portion of the Security surrendered.

         SECTION 3.07. OPTIONAL REDEMPTION. (a) Except as set forth in the next
two paragraphs and in Section 3.08, the Securities may not be redeemed prior to
October 1, 2002. On and after that date, the Company may redeem the Securities
in whole at any time or in part from time to time at the following redemption
prices

2000, the Company may redeem in the aggregate up to 33-1/3% of the original
aggregate principal amount of Securities with the proceeds of one or more Public
Equity Offerings following which there is a Public Market, at a redemption price
(expressed as a percentage of principal amount) of 108.625% plus accrued

Securities must remain outstanding after each such redemption.

         (c) Notwithstanding paragraphs (a) and (b) above, the Company shall not
redeem any Securities, other than pursuant to Section 3.08, unless,
substantially concurrently with such redemption, the Company redeems an
aggregate principal amount of Existing Securities (rounded to the nearest
integral multiple of $1,000) equal to the product of: (1) a fraction, the
numerator of which is the aggregate principal amount of Securities to be so
redeemed and the denominator of which is the aggregate principal amount of
Securities outstanding immediately prior to such proposed redemption, and (2)
the aggregate principal amount of Existing Securities outstanding immediately
prior to such proposed redemption. The Company shall not redeem the Existing
Securities unless, substantially concurrently with such redemption, the Company
redeems an aggregate principal amount of Securities (rounded to the nearest
integral multiple of $1,000) equal to the product of: (1) a fraction, the

be so redeemed and the denominator of which is the aggregate principal amount of
Existing Securities outstanding immediately prior to such proposed redemption,

         SECTION 4.01. PAYMENT OF SECURITIES. The Company shall promptly pay the
principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture. Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent (but only if other than the Company or a Wholly Owned Subsidiary) holds by
11:00 a.m., New York City time, in accordance with this Indenture available
funds sufficient to pay all principal and interest then due and the Trustee or
the Paying Agent, as the case may be, is not prohibited from paying such money
to the Securityholders on that date pursuant to the terms of this Indenture.

         The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

         SECTION 4.02. SEC REPORTS. Notwithstanding that the Company may not be
required to be subject to the reporting requirements of Section 13 or 15(d) of
the Exchange Act, the Company shall file with the SEC, and provide the Trustee

days after it files them with the SEC, copies of its annual report and the
information, documents and other reports that are specified in Section 13 or
15(d) of the Exchange Act. In addition, following a Public Equity Offering, the
Company shall furnish to the Trustee and the Securityholders, promptly upon

other information provided by the Company or Parent to its public shareholders
generally. The Company also shall comply with the other provisions of TIA
section 314(a).

         SECTION 4.03. LIMITATION ON INDEBTEDNESS. (a) The Company shall not,

PROVIDED, HOWEVER, that the Company may Incur Indebtedness if on the date
thereof the Consolidated Coverage Ratio would be greater than 2.00:1.00 if such
Indebtedness is Incurred on or prior to September 30, 1999, and 2.25:1.00 if
such Indebtedness is Incurred thereafter. Notwithstanding the foregoing, the

          (i) Bank Indebtedness relating to the Term Loan Facilities in an

     or Indebtedness of a Restricted Subsidiary owing to and held by the Company
     or any Subsidiary; PROVIDED, HOWEVER, that any subsequent issuance or
     transfer of any Capital Stock or any other event that results in any such
     Subsidiary ceasing to be a Subsidiary or any subsequent transfer of any
     such Indebtedness (except to the Company or a Restricted Subsidiary) will
     be deemed, in each case, to constitute the Incurrence of such Indebtedness
     by the issuer thereof;

          (iv) Indebtedness represented by the Securities and the Subsidiary
     Guarantees and the Existing Securities and the Existing Subsidiary
     Guarantees, any Indebtedness (other than the Indebtedness described in
     clauses (i) through (iii) above) outstanding on the Original Issue Date,

     under Section 4.03(a) and 4.03(b)(v) of the Existing Indenture and any
     Refinancing Indebtedness Incurred in respect of any Indebtedness described
     in this clause (iv) or Section 4.03(a);

          (v) (A) Indebtedness of a Restricted Subsidiary Incurred and
     outstanding on or prior to the date on which such Restricted Subsidiary was
     acquired by the Company (other than Indebtedness Incurred as consideration
     in, in contemplation of or to provide all or any portion of the funds or
     credit support utilized to consummate, the transaction or series of related
     transactions pursuant to which such Restricted Subsidiary became a
     Subsidiary or was otherwise acquired by the Company); PROVIDED, HOWEVER,
     that at the time such Restricted Subsidiary is acquired by the Company, the
     Company would have been able to Incur $1.00 of additional Indebtedness
     pursuant to Section 4.03(a) after giving effect to the Incurrence of such
     Indebtedness pursuant to this clause (v) and (B) Refinancing Indebtedness
     Incurred by a Restricted Subsidiary in respect of Indebtedness Incurred by
     such Restricted Subsidiary pursuant to this clause (v);

          (vi) Indebtedness (A) in respect of performance bonds, bankers'
     acceptances, letters of credit and surety or appeal bonds provided by the
     Company and the Restricted Subsidiaries to their customers in the ordinary
     course of their business and which do not secure other Indebtedness, and
     (B) under Currency Agreements and Interest Rate Agreements, in each case
     entered into for bona fide hedging purposes of the Company in the ordinary
     course of business; PROVIDED, HOWEVER, that, in the case of Currency
     Agreements and Interest Rate Agreements, such Currency Agreements and
     Interest Rate Agreements do not increase the Indebtedness of the Company
     outstanding at any time other than as a result of fluctuations in foreign
     currency exchange rates or interest rates or by reason of fees, indemnities
     and compensation payable thereunder;

          (vii) Purchase Money Indebtedness and Capitalized Lease Obligations in
     an aggregate principal amount not to exceed $10,000,000 at any time
     outstanding;

          (viii) Indebtedness of Restricted Subsidiaries (other than
     Indebtedness permitted to be Incurred pursuant to any other clause of this
     Section 4.03(b)) in an aggregate principal amount on the date of Incurrence
     that, when added to all other Indebtedness Incurred pursuant to this clause
     (viii) and then outstanding, will not exceed $5,000,000; or

          (ix) Indebtedness (other than Indebtedness permitted to be Incurred
     pursuant to Section 4.03(a) or any other clause of this Section 4.03(b)) in
     an aggregate principal amount on the date of Incurrence that, when added to
     all other Indebtedness Incurred pursuant to this clause (ix) and then
     outstanding, will not exceed $10,000,000.

          (c) Notwithstanding the foregoing, the Company shall not Incur any
Indebtedness pursuant to paragraph (b) above if the proceeds thereof are used,
directly or indirectly, to repay, prepay, redeem, defease, retire, refund or
refinance any Subordinated Obligations unless such Indebtedness shall be
subordinated to the Securities to at least the same extent as such Subordinated
Obligations. The Company shall not Incur any Indebtedness if such Indebtedness
is subordinate or junior in ranking in any respect to any Senior Indebtedness
unless such Indebtedness is Senior Subordinated Indebtedness or is expressly
subordinated in right of payment to Senior Subordinated Indebtedness. In
addition, the Company shall not Incur any Secured Indebtedness that is not
Senior Indebtedness unless contemporaneously therewith effective provision is
made to secure the Securities equally and ratably with (or on a senior basis to,
in the case of Indebtedness subordinated in right of payment to the Securities)
such Secured Indebtedness for so long as such Secured Indebtedness is secured by
a Lien. A Subsidiary Guarantor may not Incur any Indebtedness if such
Indebtedness is by its terms expressly subordinate or junior in ranking in any
respect to any Senior Indebtedness of such Subsidiary Guarantor unless such
Indebtedness is Senior Subordinated Indebtedness of such Subsidiary Guarantor or
is expressly subordinated in right of payment to Senior Subordinated
Indebtedness of such Subsidiary Guarantor. In addition, a Subsidiary Guarantor
may not Incur any Secured Indebtedness that is not Senior Indebtedness of such
Subsidiary Guarantor unless contemporaneously therewith effective provision is
made to secure the Subsidiary Guarantee of such Subsidiary Guarantor equally and
ratably with (or on a senior basis to, in the case of Indebtedness subordinated
in right of payment to such Subsidiary Guarantee) such Secured Indebtedness for
so long as such Secured Indebtedness is secured by a Lien.

          (d) Notwithstanding any other provision of this Section 4.03, the
maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
Incur pursuant to this Section 4.03 shall not be deemed to be exceeded solely as
a result of fluctuations in the exchange rates of currencies. For purposes of
determining the outstanding principal amount of any particular Indebtedness
Incurred pursuant to this Section 4.03, (i) Indebtedness Incurred pursuant to
the Credit Agreement prior to or on the Original Issue Date shall be treated as
Incurred pursuant to Section 4.03(b)(i), (ii) Indebtedness permitted by this
Section 4.03 need not be permitted solely by reference to one provision
permitting such Indebtedness but may be permitted in part by one such provision
and in part by one or more other provisions of this Section permitting such
Indebtedness and (iii) in the event that Indebtedness or any portion thereof
meets the criteria of more than one of the types of Indebtedness described in
this Section, the Company, in its sole discretion, shall classify such
Indebtedness and only be required to include the amount of such Indebtedness in
one of such clauses.

          SECTION 4.04. LIMITATION ON RESTRICTED PAYMENTS. (a) The Company shall
not, and shall not permit any Restricted Subsidiary, directly or indirectly, to
(i) declare or pay any dividend or make any distribution on or in respect of its
Capital Stock (including any payment in connection with any merger or
consolidation involving the Company) except dividends or distributions payable
solely in its Capital Stock (other

than Disqualified Stock) and except dividends or distributions payable to the
Company or another Restricted Subsidiary (and, if such Restricted Subsidiary is
not wholly owned, to its other shareholders on a pro rata basis), (ii) purchase,
redeem, retire or otherwise acquire for value any Capital Stock of the Company
or any Restricted Subsidiary held by Persons other than the Company or another
Restricted Subsidiary, (iii) purchase, repurchase, redeem, defease or otherwise
acquire or retire for value, prior to scheduled maturity, scheduled repayment or
scheduled sinking fund payment any Subordinated Obligations (other than the
purchase, repurchase or other acquisition of Subordinated Obligations purchased
in anticipation of satisfying a sinking fund obligation, principal installment
or final maturity, in each case due within one year of the date of acquisition)
or (iv) make any Investment (other than a Permitted Investment) in any Person
(any such dividend, distribution, purchase, redemption, repurchase, defeasance,
other acquisition, retirement or Investment being herein referred to as a
"Restricted Payment") if at the time the Company or such Restricted Subsidiary
makes such Restricted Payment:

          (1) a Default shall have occurred and be continuing (or would result
     therefrom);

          (2) the Company could not Incur at least $1.00 of additional
     Indebtedness under Section 4.03(a); or

          (3) the aggregate amount of such Restricted Payment and all other
     Restricted Payments (the amount so expended, if other than in cash, to be
     determined in good faith by the Board of Directors, whose determination
     shall be conclusive and evidenced by a resolution of the Board of
     Directors) declared or made subsequent to the Original Issue Date would
     exceed the sum of:

               (A) 50% of the Consolidated Net Income accrued during the period
          (treated as one accounting period) from the beginning of the fiscal
          quarter in which the Original Issue Date occurred to the end of the
          most recent fiscal quarter ending at least 45 days prior to the date
          of such Restricted Payment (or, in case such Consolidated Net Income
          shall be a deficit, minus 100% of such deficit);

               (B) the aggregate Net Cash Proceeds received by the Company from
          the issue or sale of its Capital Stock (other than Disqualified Stock)
          subsequent to the Original Issue Date (other than an issuance or sale
          to a Subsidiary of the Company or an employee stock ownership plan or
          other trust established by the Company or any of its Subsidiaries);
          and

               (C) the amount by which Indebtedness of the Company or its
          Restricted Subsidiaries is reduced on the Company's balance sheet upon
          the conversion or exchange (other than by a Subsidiary) subsequent to
          the Original Issue Date of any Indebtedness of the Company or its
          Restricted Subsidiaries convertible or exchangeable for Capital Stock
          (other than Disqualified Stock) of the Company (less the amount of any
          cash or other property distributed by the Company or any Restricted
          Subsidiary upon such conversion or exchange); and

               (D) the amount equal to the net reduction in Investments in
          Unrestricted Subsidiaries resulting from (i) payments of dividends,

                                                                              31

          repayments of the principal of loans or advances or other transfers of
          assets to the Company or any Restricted Subsidiary from Unrestricted
          Subsidiaries or (ii) the redesignation of Unrestricted Subsidiaries as
          Restricted Subsidiaries (valued in each case as provided in the
          definition of "Investment") not to exceed, in the case of any
          Unrestricted Subsidiary, the amount of Investments previously made by
          the Company or any Restricted Subsidiary in such Unrestricted
          Subsidiary, which amount was included in the calculation of the amount
          of Restricted Payments.

          (b) The provisions of Section 4.04(a) shall not prohibit:

          (i) any purchase or redemption of Capital Stock of the Company or
     Subordinated Obligations made by exchange for, or out of the proceeds of
     the substantially concurrent sale of, Capital Stock of the Company (other
     than Disqualified Stock and other than Capital Stock issued or sold to a
     Subsidiary or an employee stock ownership plan or other trust established
     by the Company or any of its Subsidiaries); PROVIDED, HOWEVER, that (A)
     such purchase or redemption shall be excluded in the calculation of the
     amount of Restricted Payments and (B) the Net Cash Proceeds from such sale
     applied in the manner set forth in this clause (i) shall be excluded from
     clause (3)(B) of Section 4.04(a);

          (ii) any purchase or redemption of Subordinated Obligations made by
     exchange for, or out of the proceeds of the substantially concurrent sale
     of, Indebtedness of the Company that is permitted to be Incurred pursuant
     to Section 4.03; PROVIDED, HOWEVER, that such purchase or redemption shall
     be excluded in the calculation of the amount of Restricted Payments;

          (iii) any purchase or redemption of Subordinated Obligations from Net
     Available Cash to the extent permitted by Section 4.06; PROVIDED, HOWEVER,
     that such purchase or redemption shall be excluded in the calculation of
     the amount of Restricted Payments;

          (iv) dividends paid within 60 days after the date of declaration
     thereof if at such date of declaration such dividend would have complied
     with Section 4.04(a); PROVIDED, HOWEVER, that such dividend shall be
     included in the calculation of the amount of Restricted Payments;

          (v) payment of dividends, other distributions or other amounts by the
     Company for the purposes set forth in clauses (A) through (D) below;
     PROVIDED, HOWEVER, that such dividend, distribution or amount set forth in

          to pay franchise taxes and other fees required to maintain its
          corporate existence and provide for other operating costs of up to
          $100,000 per fiscal year;

               (B) to Parent in amounts equal to amounts required for Parent to

          Stock; and

               (D) in amounts equal to amounts expended by the Company to

     to which such Restricted Subsidiary became a Restricted Subsidiary or was
     acquired by the Company) and outstanding on such date;

          (3) any encumbrance or restriction pursuant to an agreement
     constituting Refinancing Indebtedness of Indebtedness Incurred pursuant to
     an agreement referred to in clause (1) or (2) of this Section or this
     clause (3) or contained in any amendment to an agreement referred to in
     clause (1) or (2) of this Section or this clause (3); PROVIDED, HOWEVER,
     that the encumbrances and restrictions contained in any such refinancing
     agreement or amendment are no less favorable to the Securityholders than
     encumbrances and restrictions contained in such agreements;

          (4) in the case of clause (iii), any encumbrance or restriction (A)
     that restricts in a customary manner the subletting, assignment or transfer
     of any property or asset that is subject to a lease, license or similar

          SECTION 4.06. LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK. (a)
The Company shall not, and shall not permit any Restricted Subsidiary to, make
any Asset Disposition unless (i) the Company or such Restricted Subsidiary

(1) to the extent the Company elects (or is required by the terms of any Senior
Indebtedness or Indebtedness (other than Preferred Stock) of a Wholly Owned

extent of the balance of such Net Available Cash after application in accordance
with clauses (A) and (B), to prepay, repay, redeem, defease or purchase
Indebtedness of the Company (other than Indebtedness owed to an Affiliate of the
Company and other than Disqualified Stock of the Company) or Indebtedness of any
Restricted Subsidiary (other than Indebtedness owed to the Company or an
Affiliate of the Company), in each case described in this clause (C) within one
year from the receipt of such Net Available Cash or, if the Company has made an
Offer pursuant to clause (B), six months from the date such Offer is
consummated; PROVIDED, HOWEVER that in connection with any prepayment,
repayment, redemption, defeasance or purchase of Indebtedness pursuant to clause
(A), (B) or (C) above, the Company or such Restricted Subsidiary shall retire
such Indebtedness and shall cause the related loan commitment (if any) to be
permanently reduced in an amount equal to the principal amount so prepaid,
repaid, redeemed, defeased or purchased. Notwithstanding the foregoing
provisions of this covenant, the Company and the Restricted Subsidiaries shall
not be required to apply any Net Available Cash in accordance with this Section
except to the extent that the aggregate Net Available Cash from all Asset
Dispositions that is not applied in accordance with this Section 4.06 exceeds
$10,000,000.

          For the purposes of this Section 4.06, the following are deemed to be

Stock of the Company) or any Restricted Subsidiary and the release of the
Company or such Restricted Subsidiary from all liability on such Indebtedness in
connection with such Asset Disposition, (y) securities received by the Company
or any Restricted Subsidiary from the transferee that are promptly converted by
the Company or such Restricted Subsidiary into cash and (z) in the case of an
Asset Disposition relating to the Specified Real Estate, REIT Securities.

          (b) In the event of an Asset Disposition that requires the purchase of
Securities and Existing Securities pursuant to Section 4.06(a)(iii)(B), the
Company shall be required to purchase Securities and Existing Securities
tendered pursuant to an offer by the Company for the Securities and Existing
Securities (the "Offer") at a purchase price of 100% of their principal amount
plus accrued interest (if any) to the Purchase Date in accordance with the
procedures (including prorationing in the event of oversubscription) set forth
in Section 4.06(c). If the aggregate purchase price of Securities and Existing
Securities tendered pursuant to the Offer is less than the Net Available Cash
allotted to the purchase of the Securities and Existing Securities, the Company
shall apply the remaining Net Available Cash in accordance with Section
4.06(a)(iii)(C). The Company shall not be required to make an Offer for
Securities and Existing Securities pursuant to this Section if the Net Available
Cash available therefor (after application of the proceeds as provided in clause
(A) of Section 4.06(a)(iii)) is less than $5,000,000 for any particular Asset
Disposition (which lesser amount shall be carried forward for purposes of
determining whether an Offer is required with respect to the Net Available Cash
from any subsequent Asset Disposition).

          (c) (1) Promptly, and in any event within 10 days after the Company
becomes obligated to make an Offer, the Company shall be obligated to deliver to
the Trustee and send, by first-class mail to each Holder, a written notice
stating that the Holder may elect to have his Securities purchased by the
Company either in whole or in part (subject to prorationing as hereinafter
described in the event the Offer is oversubscribed) in integral multiples of
$1,000 of principal amount, at the applicable purchase price. The notice shall
specify a purchase date not less than 30 days nor more

than 60 days after the date of such notice (the "Purchase Date") and shall
contain such information concerning the business of the Company that the Company
in good faith believes will enable such Holders to make an informed decision
(which at a minimum shall include (i) the most recently filed Annual Report on
Form 10-K (including audited consolidated financial statements) of the Company,
the most recent subsequently filed Quarterly Report on Form 10-Q and any Current
Report on Form 8-K of the Company filed subsequent to such Quarterly Report,
other than Current Reports describing Asset Dispositions otherwise described in
the offering materials (or corresponding successor reports), (ii) a description
of material developments in the Company's business subsequent to the date of the
latest of such Reports, and (iii) if material, appropriate pro forma financial
information) and all instructions and materials necessary to tender Securities
pursuant to the Offer, together with the address referred to in clause (3).

          (2) Not later than the date upon which written notice of an Offer is
delivered to the Trustee as provided above, the Company shall deliver to the
Trustee an Officers' Certificate as to (i) the amount of the Offer (the "Offer
Amount"), (ii) the allocation of the Net Available Cash from the Asset
Dispositions pursuant to which such Offer is being made and (iii) the compliance
of such allocation with the provisions of Section 4.06(a). On such date, the
Company shall also irrevocably deposit with the Trustee or with a paying agent
(or, if the Company is acting as its own paying agent, segregate and hold in
trust) an amount equal to the Offer Amount to be invested in Temporary Cash
Investments and to be held for payment in accordance with the provisions of this
Section. Upon the expiration of the period for which the Offer remains open (the
"Offer Period"), the Company shall deliver to the Trustee for cancelation the
Securities or portions thereof that have been properly tendered to and are to be
accepted by the Company. The Trustee (or the Paying Agent, if not the Trustee)
shall, on the Purchase Date, mail or deliver payment to each tendering Holder in
the amount of the purchase price. In the event that the aggregate purchase price
of the Securities delivered by the Company to the Trustee is less than the Offer
Amount, the Trustee shall deliver the excess to the Company immediately after
the expiration of the Offer Period for application in accordance with this
Section.

          (3) Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
at the address specified in the notice at least three Business Days prior to the

Trustee or the Company receives not later than one Business Day prior to the
Purchase Date, a telegram, telex, facsimile transmission or letter setting forth
the name of the Holder, the principal amount of the Security that was delivered
by the Holder for purchase and a statement that such Holder is withdrawing his
election to have such Security purchased. If at the expiration of the Offer
Period the aggregate principal amount of Securities surrendered by Holders
exceeds the Offer Amount, the Company shall select the Securities to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Company so that only Securities in denominations of $1,000,
or integral multiples thereof, shall be purchased). Holders whose Securities are
purchased only in part will be issued new Securities equal in principal amount
to the unpurchased portion of the Securities surrendered.

          (4) At the time the Company delivers Securities to the Trustee that
are to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Company
pursuant to and in accordance

with the terms of this Section. A Security shall be deemed to have been accepted
for purchase at the time the Trustee, directly or through an agent, mails or
delivers payment therefor to the surrendering Holder.

          (d) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section. To the extent that the provisions of any securities laws or regulations

breached its obligations under this Section by virtue thereof.

          SECTION 4.07. LIMITATION ON TRANSACTIONS WITH AFFILIATES. (a) The
Company shall not, and shall not permit any Restricted Subsidiary to, directly
or indirectly, enter into or conduct any transaction (including, the purchase,
sale, lease or exchange of any property or the rendering of any service) with
any Affiliate of the Company (an "Affiliate Transaction") on terms (i) that are
less favorable to the Company or such Restricted Subsidiary, as the case may be,
than those that could be obtained at the time of such transaction in
arm's-length dealings with a Person who is not such an Affiliate and (ii) that,
in the event such Affiliate Transaction involves an aggregate amount in excess
of $10,000,000, are not in writing and have not been approved by a majority of
the members of the Board of Directors having no personal stake in such Affiliate
Transaction and who are not employed by or otherwise associated with such
Affiliate. In addition, if such Affiliate Transaction involves an amount in
excess of $15,000,000, a fairness opinion must be provided by a nationally
recognized appraisal or investment banking firm.

          (b) The provisions of Section 4.07(a) shall not prohibit (i) any
Restricted Payment permitted to be paid pursuant to Section 4.04, (ii) any

or otherwise pursuant to, or the funding of, employment arrangements, stock
options and stock ownership plans approved by the Board of Directors, (iii)

to directors of the Company and its Subsidiaries who are not employees of the
Company or its Subsidiaries, (v) any transaction between the Company and a
Wholly Owned Subsidiary or between Wholly Owned Subsidiaries or (vi)

Issue Date.

          SECTION 4.08. CHANGE OF CONTROL. (a) Upon a Change of Control, each
Holder shall have the right to require that the Company repurchase all or any
part of such Holder's Securities at a purchase price in cash equal to 101% of
the principal amount thereof plus accrued and unpaid interest (if any) to the
date of purchase (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), in
accordance with the terms contemplated in Section 4.08(b). In the event that at
the time of such Change of Control the terms of the Bank Indebtedness restrict
or prohibit the repurchase of Securities pursuant to this Section, then prior to
the mailing of the notice to Holders provided for in Section 4.08(b) below but
in any event within 30 days following any Change of Control, the Company shall
(i) repay in full all Bank Indebtedness or offer to repay in full all Bank

     right to require the Company to purchase such Holder's Securities at a
     purchase price in cash equal to 101% of the principal amount thereof, plus
     accrued and unpaid interest (if any) to the date of purchase (subject to
     the right of Holders of record on the relevant record date to receive
     interest on the relevant interest payment date);

          (2) the circumstances and relevant facts and financial information
     regarding such Change of Control;

     later than 60 days from the date such notice is mailed); and

          (4) the instructions determined by the Company, consistent with this
     Section, that a Holder must follow in order to have its Securities
     purchased.

          (c) Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
at the address specified in the notice at least three Business Days prior to the
purchase date. Holders shall be entitled to withdraw their election if the
Trustee or the Company receives not later than one Business Day prior to the
purchase date a telegram, telex, facsimile transmission or letter setting forth
the name of the Holder, the principal amount of the Security that was delivered
for purchase by the Holder and a statement that such Holder is withdrawing his
election to have such Security purchased.

          (d) On the purchase date, all Securities purchased by the Company
under this Section shall be delivered to the Trustee for cancelation, and the
Company shall pay the purchase price plus accrued and unpaid interest (if any)
to the Holders entitled thereto.

          (e) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section by virtue thereof.

          SECTION 4.09. COMPLIANCE CERTIFICATE. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the

voidable under applicable law relating to fraudulent conveyance or fraudulent
transfer or similar laws affecting the rights of creditors generally.

<PAGE>   48


                                                                              42

          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 clause (4) or (5) is not an Event of Default until the
Trustee or the Holders of at least 25% in principal amount of the outstanding
Securities notify the Company of the Default and the Company does not cure such
Default within the time specified in clauses (4) or (5) 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".

          The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (6) and any event that with the giving of
notice or the lapse of time would become an Event of Default under clause (4),
(5) or (9), its status and what action the Company is taking or proposes to take
with respect thereto.

          SECTION 6.02. ACCELERATION. If an Event of Default (other than an
Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the outstanding Securities by
notice to the Company, may declare the principal of and accrued but unpaid
interest on all the Securities 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 6.01(7) or (8) with respect to the Company occurs,
the principal of and interest on all the Securities shall IPSO FACTO become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Securityholders. The Holders of a majority in principal
amount of the Securities by notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

          SECTION 6.03. OTHER REMEDIES. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce 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.

          SECTION 6.04. WAIVER OF PAST DEFAULTS. The Holders of a majority in
principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except (i) a Default in the payment of the
principal of or interest on a Security or (ii) a Default in respect of a
provision that under Section 9.02 cannot be amended without the consent of each
Securityholder affected. When a Default is waived,


<PAGE>   49


                                                                              43

it is deemed cured, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.

          SECTION 6.05. CONTROL BY MAJORITY. The Holders of a majority in
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability; PROVIDED, HOWEVER, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action hereunder, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

          SECTION 6.06. LIMITATION ON SUITS. A Securityholder may not pursue any
remedy with respect to this Indenture or the Securities unless:

          (1) the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

          (2) the Holders of at least 25% in principal amount of the Securities
     make a written request to the Trustee to pursue the remedy;

          (3) such Holder or Holders offer to the Trustee reasonable security or
     indemnity against any loss, liability or expense;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of security or indemnity; and

          (5) the Holders of a majority in principal amount of the Securities do
     not give the Trustee a direction inconsistent with the request during such
     60-day period.

          A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

          SECTION 6.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and liquidated damages and interest on the Securities
held by such Holder, on or after the respective due dates expressed in the
Securities, or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

          SECTION 6.08. COLLECTION SUIT BY TRUSTEE. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

          SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, any Subsidiary or
Subsidiary Guarantor, their creditors or their property and, unless prohibited
by law or applicable regulations, may vote on behalf of the Holders in any
election of a trustee in bankruptcy or other Person performing similar
functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and any other amounts due the Trustee under Section 7.07.

          SECTION 6.10. PRIORITIES. If the Trustee collects any money or
property pursuant to this Article 6, it shall pay out the money or property in
the following order:

          FIRST: to the Trustee for amounts due under Section 7.07;

          SECOND: to holders of Senior Indebtedness to the extent required by
     Article 10;

          THIRD: to Securityholders for amounts due and unpaid on the Securities
     for principal and interest, ratably, and any liquidated damages without
     preference or priority of any kind, according to the amounts due and
     payable on the Securities for principal, any liquidated damages and
     interest, respectively; and

          FOURTH: to the Company.

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section. At least 15 days before such record
date, the Trustee shall mail to each Securityholder and the Company a notice
that states the record date, the payment date and amount to be paid.

          SECTION 6.11. UNDERTAKING FOR COSTS. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, 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. This Section does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of
more than 10% in principal amount of the Securities.

          SECTION 6.12. WAIVER OF STAY OR EXTENSION LAWS. Neither the Company
nor any Subsidiary Guarantor (to the extent it may lawfully do so) shall 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, that may affect the covenants or the performance of
this Indenture; and the Company and each Subsidiary Guarantor (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


<PAGE>   51


                                                                              45

impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law had
been enacted.


                                    ARTICLE 7

                                     TRUSTEE

          SECTION 7.01. DUTIES OF TRUSTEE. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

          (b) Except during the continuance of an Event of Default:

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

          (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

          (1) this paragraph does not limit the effect of paragraph (b) of this
     Section;

          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts; and

          (3) the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05.

          (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

          (e) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company.

          (f) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

                                                                              46

          (g) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur financial liability in the performance
of any of its duties hereunder or in the exercise of any of its rights or
powers, if it shall have reasonable grounds to believe that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it.

          (h) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

          SECTION 7.02. RIGHTS OF TRUSTEE. Subject to Section 7.01: (a) The
Trustee may rely on any document believed by it to be genuine and to have been
signed or presented by the proper person. The Trustee need not investigate any
fact or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on the
Officers' Certificate or Opinion of Counsel.

          (c) The Trustee may act through agents and shall not be responsible
for the misconduct or negligence of any agent appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith that it believes to be authorized or within its rights or
powers; PROVIDED, HOWEVER, that the Trustee's conduct does not constitute wilful
misconduct or negligence.

          (e) The Trustee may consult with counsel, and the advice or opinion of
counsel with respect to legal matters relating to this Indenture and the
Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

          (f) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, debenture,
note or other paper or document unless requested in writing to do so by the
Holders of not less than a majority in principal amount of the Securities at the
time outstanding, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit, and, if
the Trustee shall determine to make such further inquiry or investigation, it
shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney.

          (g) The Trustee shall not be required to give any note, bond or surety
in respect of the execution of the trusts and powers under this Indenture.

          (h) The permissive rights of the Trustee to take any action enumerated
in this Indenture shall not be construed as a duty to take such action.

          SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may


<PAGE>   53


                                                                              47

otherwise deal with the Company or its Affiliates with the same rights it would
have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or
co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

          SECTION 7.04. TRUSTEE'S DISCLAIMER. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's
use of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the
Trustee's certificate of authentication.

          SECTION 7.05. NOTICE OF DEFAULTS. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within the earlier of 90 days after it
occurs or 30 days after it is known to a trust officer. Except in the case of a
Default in payment of principal of or interest on any Security (including
payments pursuant to the mandatory redemption provisions of such Security, if
any), the Trustee may withhold the notice if and so long as a committee of its
Trust Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

          SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS. As promptly as
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 15 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of May 15 that
complies with Section 313(a) of the TIA. The Trustee shall also comply with
Section 313(b) of the TIA.

          A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each stock exchange (if any) on which the
Securities are listed. The Company agrees to notify promptly the Trustee
whenever the Securities become listed on any stock exchange and of any delisting
thereof.

          SECTION 7.07. COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Company and each Subsidiary Guarantor, jointly and severally shall
indemnify the Trustee against any and all loss, liability or expense (including
reasonable attorneys' fees) incurred by them without negligence or bad faith on
their part in connection with the administration of this trust and the
performance of their duties hereunder. The Trustee shall notify the Company of
any claim for which it may seek indemnity promptly upon obtaining actual
knowledge thereof; PROVIDED that any failure so to notify the Company shall not
relieve the Company or any Subsidiary Guarantor of its indemnity obligations
hereunder. The Company shall defend the claim and the indemnified party shall
provide reasonable cooperation at the Company's expense in the defense. Such
indemnified parties may have separate counsel and the Company shall pay the fees
and expenses of such counsel; PROVIDED that the Company shall not be required to
pay such fees and expenses if it assumes such indemnified parties' defense and,
in such


<PAGE>   54


                                                                              48

indemnified parties' reasonable judgment, there is no conflict of interest
between the Company and such parties in connection with such defense. The
Company need not reimburse any expense or indemnify against any loss, liability
or expense incurred by an indemnified party through such party's own wilful
misconduct, negligence or bad faith.

          To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest and any liquidated damages on particular Securities.

          The Company's payment obligations pursuant to this Section shall
survive the satisfaction or discharge of this Indenture, any rejection or
termination of this Indenture under any bankruptcy law or the resignation or
removal of the Trustee. When the Trustee incurs expenses after the occurrence of
a Default specified in Section 6.01(7) or (8) with respect to the Company, the
expenses are intended to constitute expenses of administration under the
Bankruptcy Law.

          SECTION 7.08. REPLACEMENT OF TRUSTEE. The Trustee may resign at any
time by so notifying the Company. The Holders of a majority in principal amount
of the Securities may remove the Trustee by so notifying the Trustee and may
appoint a successor Trustee. The Company shall remove the Trustee if:

          (1) the Trustee fails to comply with Section 7.10;

          (2) the Trustee is adjudged bankrupt or insolvent;

          (3) a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4) the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns, is removed by the Company or by the Holders of
a majority in principal amount of the Securities and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% in principal amount of the Securities may petition any court of competent
jurisdiction for the appointment of a successor Trustee.



<PAGE>   55


                                                                              49

          If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

          SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

          In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee; and in
all such cases such certificates shall have the full force that it is anywhere
in the Securities or in this Indenture provided that the certificate of the
Trustee shall have.

          SECTION 7.10. ELIGIBILITY; DISQUALIFICATION. The Trustee shall at all
times satisfy the requirements of TIA section 310(a). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA section 310(b)(1) any indenture oR indentures under which other
securities or certificates of interest or participation in other securities of
the Company are outstanding if the requirements for such exclusion set forth in
TIA section 310(b)(1) are met.

          SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The
Trustee shall comply with TIA section 311(a), excluding any creditor
relationship listed in TIA section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA section 311(a) to the extent indicated.


                                    ARTICLE 8

                       DISCHARGE OF INDENTURE; DEFEASANCE

          SECTION 8.01. DISCHARGE OF LIABILITY ON SECURITIES; DEFEASANCE. (a)
When (i) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.07) for cancelation or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article 3 hereof and
the Company irrevocably deposits with the Trustee funds or U.S. Government
Obligations on which payment of principal and interest when due will be
sufficient to pay at maturity or upon redemption


<PAGE>   56


                                                                              50

all outstanding Securities, including interest thereon to maturity or such
redemption date (other than Securities replaced pursuant to Section 2.07), and
if in either case the Company pays all other sums payable hereunder by the
Company, then this Indenture shall, subject to Section 8.01(c), cease to be of
further effect. The Trustee shall acknowledge satisfaction and discharge of
this Indenture on demand of the Company accompanied by an Officers' Certificate
and an Opinion of Counsel and at the cost and expense of the Company.

          (b) Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (i) all of its obligations under the Securities and this Indenture
("legal defeasance option") or (ii) its obligations under Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.08, 4.11, 4.12, 4.13, 4.14, 4.15, 5.01(iii) and
5.01(iv) and the operation of Section 6.01(4), 6.01(6), 6.01(7) (with respect to
Subsidiaries of the Company only), 6.01(9) (with respect to Subsidiaries of the
Company only) and 6.01(10) ("covenant defeasance option"). The Company may
exercise its legal defeasance option notwithstanding its prior exercise of its
covenant defeasance option.

          If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default. If the Company
exercises its covenant defeasance option, payment of the Securities may not be
accelerated because of an Event of Default specified in Section 6.01(4),
6.01(6), 6.01(7) (with respect to Subsidiaries of the Company only), 6.01(9)
(with respect to Subsidiaries of the Company only) and 6.01(10) or because of
the failure of the Company to comply with (iii) and (iv) of Section 5.01.

          Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

          (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 7.07, 7.08, 8.04, 8.05 and
8.06 shall survive until the Securities have been paid in full. Thereafter, the
Company's obligations in Sections 7.07, 8.04 and 8.05 shall survive.

          SECTION 8.02. CONDITIONS TO DEFEASANCE. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

          (1) the Company irrevocably deposits in trust with the Trustee money
     or U.S. Government Obligations for the payment of principal, premium (if
     any) and interest on the Securities to maturity or redemption, as the case
     may be;

          (2) the Company delivers to the Trustee a certificate from a
     nationally recognized firm of independent accountants expressing their
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Securities to maturity or redemption, as the case may be;



<PAGE>   57


                                                                              51

          (3) 123 days pass after the deposit is made and during the 123-day
     period no Default specified in Section 6.01(7) or (8) with respect to the
     Company occurs which is continuing at the end of the period;

          (4) the deposit does not constitute a default under any other
     agreement binding on the Company and is not prohibited by Article 10;

          (5) the Company delivers to the Trustee an Opinion of Counsel to the
     effect that the trust resulting from the deposit does not constitute, or is
     qualified as, a regulated investment company under the Investment Company
     Act of 1940;

          (6) in the case of the legal defeasance option, the Company shall have
     delivered to the Trustee an Opinion of Counsel stating that (i) the Company
     has received from, or there has been published by, the Internal Revenue
     Service a ruling, or (ii) 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 of Counsel shall confirm that,
     the Securityholders will not recognize income, gain or loss for Federal
     income tax purposes as a result of such 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 defeasance had not occurred;

          (7) in the case of the covenant defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Security holders 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; and

          (8) the Company delivers to the Trustee an Officers' Certificate and
     an Opinion of Counsel, each stating that all conditions precedent to the
     defeasance and discharge of the Securities as contemplated by this Article
     8 have been complied with.

          Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

          SECTION 8.03. APPLICATION OF TRUST MONEY. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
Article 8. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to
the payment of principal of and interest on the Securities. Money and securities
so held in trust are not subject to Article 10.

          SECTION 8.04. REPAYMENT TO COMPANY. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

          Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon written request any money held by
them


<PAGE>   58


                                                                              52

for the payment of principal or interest that remains unclaimed for two years,
and, thereafter, Securityholders entitled to the money must look to the Company
for payment as general creditors.

          SECTION 8.05. INDEMNITY FOR GOVERNMENT OBLIGATIONS. The Company shall
pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited U.S. Government Obligations or the principal
and interest received on such U.S. Government Obligations.

          SECTION 8.06. REINSTATEMENT. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with this
Article 8 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, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee
or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8; PROVIDED, HOWEVER, that, if the
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its 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.

          SECTION 8.07. CONCURRENT DEFEASANCE OF SECURITIES AND EXISTING
SECURITIES. The Company will not be permitted to exercise either defeasance
option described above with respect to the Securities unless it defeases
Existing Securities equivalently and substantially simultaneously. Similarly,
the Company will not be permitted to defease Existing Securities unless it
defeases the Securities equivalently and substantially simultaneously.


                                    ARTICLE 9

                                   AMENDMENTS

          SECTION 9.01. WITHOUT CONSENT OF HOLDERS. The Company and the Trustee
may amend this Indenture or the Securities without notice to or consent of any
Securityholder:

          (1) to cure any ambiguity, omission, defect or inconsistency;

          (2) to comply with Article 5;

          (3) to provide for uncertificated Securities in addition to or in
     place of certificated Securities; PROVIDED, HOWEVER, that the
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the Code or in a manner such that the uncertificated
     Securities are described in Section 163(f)(2)(B) of the Code;

          (4) to make any change in Article 10 that would limit or terminate the
     benefits available to any holder of Senior Indebtedness (or Representatives
     therefor) under Article 10;


<PAGE>   59


                                                                              53

          (5) to add further Guarantees with respect to the Securities or to
     secure the Securities;

          (6) to add to the covenants of the Company for the benefit of the
     Holders or to surrender any right or power herein conferred upon the
     Company;

          (7) to comply with any requirements of the SEC in connection with
     qualifying this Indenture under the TIA;

          (8) to make any change that does not adversely affect the rights of
     any Securityholder; or

          (9) to provide for the issuance of the Exchange Securities or Private
     Exchange Securities, which shall have terms substantially identical in all
     material respects to the Initial Securities (except that the transfer
     restrictions contained in the Initial Securities shall be modified or
     eliminated, as appropriate), and which shall be treated, together with any
     outstanding Initial Securities, as a single issue of securities.

          An amendment under this Section may not make any change that adversely
affects the rights under Article 10 of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or any group or
representative thereof authorized to give a consent) consent to such change.

          After an amendment under this Section becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

          SECTION 9.02. WITH CONSENT OF HOLDERS. The Company, the Subsidiary
Guarantors and the Trustee may amend this Indenture or the Securities without
notice to any Securityholder but with the written consent of the Holders of at
least a majority in principal amount of the Securities. However, without the
consent of each Securityholder affected, an amendment may not:

          (1) reduce the amount of Securities whose Holders must consent to an
     amendment;

          (2) reduce the rate of or extend the time for payment of interest or
     any liquidated damages on any Security;

          (3) reduce the principal of or extend the Stated Maturity of any
     Security;

          (4) reduce the premium payable upon the redemption of any Security or
     change the time at which any Security may be redeemed in accordance with
     Article 3;

          (5) make any Security payable in money other than that stated in the
     Security;



<PAGE>   60


                                                                              54

          (6) make any change in Article 10 that adversely affects the rights of
     any Securityholder under Article 10;

          (7) make any change in Section 6.04 or 6.07 or the second sentence of
     this Section; or

          (8) modify or affect in any manner adverse to the Holders the terms
     and conditions of the obligation of any Subsidiary Guarantor for the due
     and punctual payment of the principal of or any liquidated damages or
     interest on Securities.

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

          An amendment under this Section may not make any change that adversely
affects the rights under Article 10 of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or any group or
representative thereof authorized to give a consent) consent to such change.

          After an amendment under this Section becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

          SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to
this Indenture or the Securities shall comply with the TIA as then in effect.

          SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS AND WAIVERS. A consent
to an amendment or a waiver by a Holder of a Security shall bind the Holder and
every subsequent Holder of that Security or portion of the Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder's Security
or portion of the Security if the Trustee receives the notice of revocation
before the date on which the Trustee receives an Officers' Certificate from the
Company certifying that the requisite number of consents has been received.
After an amendment or waiver becomes effective, it shall bind every
Securityholder. An amendment or waiver becomes effective upon the (i) receipt by
the Company or the Trustee of the requisite number of consents, (ii)
satisfaction of conditions to effectiveness as set forth in this Indenture and
an indenture supplemental hereto containing such amendment or waiver (iii)
execution by the Company and the Trustee of such amendment or waiver.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Securityholders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Securityholders at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such


<PAGE>   61


                                                                              55

Persons continue to be Holders after such record date. No such consent shall be
valid or effective for more than 120 days after such record date.

          SECTION 9.05. NOTATION ON OR EXCHANGE OF SECURITIES. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding 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 to issue a new Security shall not affect the validity of such
amendment.

          SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS. The Trustee shall sign any
amendment authorized pursuant to this Article 9 if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture that such amendment is
the legal, valid and binding obligation of the Company and the Subsidiary
Guarantors enforceable against them in accordance with its terms, subject to
customary exceptions, and complies with the provisions hereof (including Section
9.03).

          SECTION 9.07. PAYMENT FOR CONSENT. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.


                                   ARTICLE 10

                                  SUBORDINATION

          SECTION 10.01. AGREEMENT TO SUBORDINATE. The Company agrees, and each
Securityholder by accepting a Security agrees, that the Indebtedness evidenced
by the Securities is subordinated in right of payment, to the extent and in the
manner provided in this Article 10, to the prior payment in full of all Senior
Indebtedness and that the subordination is for the benefit of and enforceable by
the holders of Senior Indebtedness. The Securities shall in all respects rank
PARI PASSU with all other Senior Subordinated Indebtedness of the Company,
including, without limitation, the Existing Securities, and only Indebtedness of
the Company that is Senior Indebtedness shall rank senior to the Securities in
accordance with the provisions set forth herein. For purposes of these
subordination provisions, the Indebtedness evidenced by the Securities is deemed
to include the liquidated damages payable pursuant to the provisions set forth
in the Registration Agreement. All provisions of this Article 10 shall be
subject to Section 10.12.



<PAGE>   62


                                                                              56

          SECTION 10.02. LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any payment
or distribution of the assets of the Company to creditors upon a total or
partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property:

          (1) holders of Senior Indebtedness shall be entitled to receive
     payment in full of the Senior Indebtedness before Securityholders shall be
     entitled to receive any payment of principal of or interest on the
     Securities; and

          (2) until the Senior Indebtedness is paid in full, any payment or
     distribution to which Securityholders would be entitled but for this
     Article 10 shall be made to holders of Senior Indebtedness as their
     interests may appear, except that Securityholders may receive shares of
     stock and any debt securities that are subordinated to Senior Indebtedness
     to at least the same extent as the Securities.

          SECTION 10.03. DEFAULT ON SENIOR INDEBTEDNESS. The Company may not pay
the principal of, premium (if any) or interest on the Securities or make any
deposit pursuant to Section 8.01 and may not repurchase, redeem or otherwise
retire any Securities (collectively, "pay the Securities") if (i) any Senior
Indebtedness is not paid when due or (ii) any other default on Senior
Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated
in accordance with its terms unless, in either case, (x) the default has been
cured or waived and any such acceleration has been rescinded or (y) such Senior
Indebtedness has been paid in full; PROVIDED, HOWEVER, that the Company may pay
the Securities without regard to the foregoing if the Company and the Trustee
receive written notice approving such payment from the Representative of the
Designated Senior Indebtedness with respect to which either of the events in
clause (i) or (ii) of this sentence has occurred and is continuing. During the
continuance of any default (other than a default described in clause (i) or (ii)
of the preceding sentence) with respect to any Designated Senior Indebtedness
pursuant to which the maturity thereof may be accelerated immediately without
further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, the Company may
not pay the Securities for a period (a "Payment Blockage Period") commencing
upon the receipt by the Trustee (with a copy to the Company) of written notice
(a "Blockage Notice") of such default from the Representative of such Designated
Senior Indebtedness specifying an election to effect a Payment Blockage Period
and ending 179 days thereafter (or earlier if such Payment Blockage Period is
terminated (i) by written notice to the Trustee and the Company from the Person
or Persons who gave such Blockage Notice, (ii) by repayment in full of such
Designated Senior Indebtedness or (iii) because the default giving rise to such
Blockage Notice is no longer continuing). Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions
contained in the first sentence of this Section), unless the holders of such
Designated Senior Indebtedness or the Representative of such holders shall have
accelerated the maturity of such Designated Senior Indebtedness, the Company may
resume payments on the Securities after the end of such Payment Blockage Period,
including any missed payments. Not more than one Blockage Notice may be given in
any consecutive 360-day period, irrespective of the number of defaults with
respect to Designated Senior Indebtedness during such period; PROVIDED, HOWEVER,
that if any Blockage Notice within such 360-day period is given by or on behalf
of any holders of Designated Senior Indebtedness other than the Bank
Indebtedness, the


<PAGE>   63


                                                                              57

Representative of the Bank Indebtedness may give another Blockage Notice within
such period; PROVIDED FURTHER, HOWEVER, that in no event may the total number of
days during which any Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any 360 consecutive day period. For purposes of
this Section, no default or event of default that existed or was continuing on
the date of the commencement of any Payment Blockage Period with respect to the
Designated Senior Indebtedness initiating such Payment Blockage Period shall be,
or be made, the basis of the commencement of a subsequent Payment Blockage
Period by the Representative of such Designated Senior Indebtedness, whether or
not within a period of 360 consecutive days, unless such default or event of
default shall have been cured or waived for a period of not less than 90
consecutive days.

          SECTION 10.04. ACCELERATION OF PAYMENT OF SECURITIES. If payment of
the Securities is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of the Designated Senior Indebtedness
(or their Representative) of the acceleration. If any Designated Senior
Indebtedness is outstanding, the Company may not pay the Securities until five
Business Days after such holders (or their Representative) of the Designated
Senior Indebtedness receive notice of such acceleration and, thereafter, may pay
the Securities only if this Article 10 otherwise permits payment at that time.

          SECTION 10.05. WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution
is made to Securityholders that because of this Article 10 should not have been
made to them, the Securityholders who receive the distribution shall hold it in
trust for holders of Senior Indebtedness and pay it over to them as their
interests may appear.

          SECTION 10.06. SUBROGATION. After all Senior Indebtedness is paid in
full and until the Securities are paid in full, Securityholders shall be
subrogated to the rights of holders of Senior Indebtedness to receive
distributions applicable to Senior Indebtedness. A distribution made under this
Article 10 to holders of Senior Indebtedness that otherwise would have been made
to Securityholders is not, as between the Company and Securityholders, a payment
by the Company on Senior Indebtedness.

          SECTION 10.07. RELATIVE RIGHTS. This Article 10 defines the relative
rights of Securityholders and holders of Senior Indebtedness. Nothing in this
Indenture shall:

          (1) impair, as between the Company and Securityholders, the obligation
     of the Company, which is absolute and unconditional, to pay principal of
     and interest on the Securities in accordance with their terms; or

          (2) prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default, subject to the rights of holders of
     Senior Indebtedness to receive distributions otherwise payable to
     Securityholders.

          SECTION 10.08. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY. No right
of any holder of Senior Indebtedness to enforce the subordination of the
Indebtedness evidenced by the Securities shall be impaired by any act or failure
to act by the Company or by its failure to comply with this Indenture.



<PAGE>   64


                                                                              58

          SECTION 10.09. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 10.03, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article 10. The Company, the Registrar or co-registrar, the Paying Agent, a
Representative or a holder of Senior Indebtedness may give the notice; PROVIDED,
HOWEVER, that, if an issue of Senior Indebtedness has a Representative, only the
Representative may give the notice. The Trustee shall be entitled to rely on the
delivery to it of a written notice by a Person representing himself or itself to
be a holder of any Senior Indebtedness (or a Representative of such holder) to
establish that such notice has been given by a holder of such Senior
Indebtedness or Representative thereof.

          The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee. The
Registrar and co-registrar and the Paying Agent may do the same with like
rights. The Trustee shall be entitled to all the rights set forth in this
Article 10 with respect to any Senior Indebtedness that may at any time be held
by it, to the same extent as any other holder of Senior Indebtedness; and
nothing in Article 7 shall deprive the Trustee of any of its rights as such
holder. Nothing in this Article 10 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.07.

          SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness,
the distribution may be made and the notice given to their Representative (if
any).

          SECTION 10.11. ARTICLE 10 NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO ACCELERATE. The failure to make a payment pursuant to the Securities by
reason of any provision in this Article 10 shall not be construed as preventing
the occurrence of a Default. Nothing in this Article 10 shall have any effect on
the right of the Secu rityholders or the Trustee to accelerate the maturity of
the Securities.

          SECTION 10.12. TRUST MONEYS NOT SUBORDINATED. Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of U.S.
Government Obligations held in trust under Article 8 by the Trustee for the
payment of principal of and interest on the Securities shall not be subordinated
to the prior payment of any Senior Indebtedness or subject to the restrictions
set forth in this Article 10, and none of the Securityholders shall be obligated
to pay over any such amount to the Company or any holder of Senior Indebtedness
of the Company or any other creditor of the Company.

          SECTION 10.13. TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 10, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 10.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior
Indebtedness for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of the Senior Indebtedness and
other Indebtedness of the Company, the amount thereof or payable thereon, the
amount


<PAGE>   65


                                                                              59

or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article 10. In the event that the Trustee determines, in good faith,
that evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article 10, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and other facts pertinent to the rights of such
Person under this Article 10, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment. The provisions of Sections
7.01 and 7.02 shall be applicable to all actions or omissions of actions by the
Trustee pursuant to this Article 10.

          SECTION 10.14. TRUSTEE TO EFFECTUATE SUBORDINATION. Each
Securityholder by accepting a Security authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Senior Indebtedness as provided in this Article 10 and appoints the Trustee as
attorney-in-fact for any and all such purposes.

          SECTION 10.15. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall mistakenly pay over or distribute to Securityholders or the Company or any
other Person, money or assets to which any holders of Senior Indebtedness shall
be entitled by virtue of this Article 10 or otherwise.

          SECTION 10.16. RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS ON
SUBORDINATION PROVISIONS. Each Securityholder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior
Indebtedness, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Securities, to acquire and continue to hold, or to
continue to hold, such Senior Indebtedness and such holder of Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Indebtedness.

          SECTION 10.17. TRUSTEE'S COMPENSATION NOT PREJUDICED. Nothing in this
Article shall apply to amounts due to the Trustee pursuant to other sections of
this Indenture.


                                   ARTICLE 11

                              SUBSIDIARY GUARANTEES

          SECTION 11.01. SUBSIDIARY GUARANTEES. Each Subsidiary Guarantor hereby
jointly and severally unconditionally and irrevocably guarantees, as a primary
obligor and not merely as a surety, to each Holder and to the Trustee and its
successors and assigns (a) the full and punctual payment of principal of and
interest on the Securities when due, whether at maturity, by acceleration, by
redemption or otherwise,


<PAGE>   66


                                                                              60

and all other monetary obligations of the Company under this Indenture
(including obligations to the Trustee) and the Securities and (b) the full and
punctual performance within applicable grace periods of all other obligations of
the Company whether for expenses, indemnification or otherwise under this
Indenture and the Securities (all the foregoing being hereinafter collectively
called the "Obligations"). Each Subsidiary Guarantor further agrees that the
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from each such Subsidiary Guarantor, and that each such
Subsidiary Guarantor shall remain bound under this Article 11 notwithstanding
any extension or renewal of any Obligation.

          Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Obligations and also waives notice
of protest for nonpayment. Each Subsidiary Guarantor waives notice of any
default under the Securities or the Obligations. The obligations of each
Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any
Holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Company or any other Person under this Indenture, the
Securities or any other agreement or otherwise; (b) any extension or renewal of
any thereof; (c) any rescission, waiver, amendment or modification of any of the
terms or provisions of this Indenture, the Securities or any other agreement;
(d) the release of any security held by any Holder or the Trustee for the
Obligations or any of them; (e) the failure of any Holder or Trustee to exercise
any right or remedy against any other guarantor of the Obligations; or (f) any
change in the ownership of such Subsidiary Guarantor, except as provided in
Section 11.02(b).

          Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee
herein constitutes a guarantee of payment, performance and compliance when due
(and not a guarantee of collection) and waives any right to require that any
resort be had by any Holder or the Trustee to any security held for payment of
the Obligations.

          The obligations of each Subsidiary Guarantor hereunder shall not be
subject to any reduction, limitation, impairment or termination for any reason,
including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or
termination whatsoever or by reason of the invalidity, illegality or
unenforceability of the Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Subsidiary Guarantor herein
shall not be discharged or impaired or otherwise affected by the failure of any
Holder or the Trustee to assert any claim or demand or to enforce any remedy
under this Indenture, the Securities or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or
otherwise, in the performance of the Obligations, or by any other act or thing
or omission or delay to do any other act or thing that may or might in any
manner or to any extent vary the risk of any Subsidiary Guarantor or would
otherwise operate as a discharge of any Subsidiary Guarantor as a matter of law
or equity.

          Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee
herein shall continue to be effective or be reinstated, as the case may be, if
at any time payment, or any part thereof, of principal of or interest on any
Obligation is rescinded or must otherwise be restored by any Holder or the
Trustee upon the bankruptcy or reorganization of the Company or otherwise.

                                                                              61

          In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Obligation when and as the same shall become
due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or comply with any other Obligation, each Subsidiary Guarantor hereby
promises to and shall, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal
to the sum of (i) the unpaid principal amount of such Obligations, (ii) accrued
and unpaid interest on such Obligations (but only to the extent not prohibited
by law) and (iii) all other monetary Obligations of the Company to the Holders
and the Trustee.

          Each Subsidiary Guarantor agrees that it shall not be entitled to any
right of subrogation in relation to the Holders in respect of any Obligations
guaranteed hereby until payment in full of all Obligations. Each Subsidiary
Guarantor further agrees that, as between it, on the one hand, and the Holders
and the Trustee, on the other hand, (x) the maturity of the Obligations
guaranteed hereby may be accelerated as provided in Article VI for the purposes
of any Subsidiary Guarantee herein, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the Obligations
guaranteed hereby, and (y) in the event of any declaration of acceleration of
such Obligations as provided in Article VI, such Obligations (whether or not due
and payable) shall forthwith become due and payable by such Subsidiary Guarantor
for the purposes of this Section.

          Each Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees and expenses) incurred by the
Trustee or any Holder in enforcing any rights under this Section.

          SECTION 11.02. LIMITATION ON LIABILITY. (a) Any term or provision of
this Indenture to the contrary notwithstanding, the maximum, aggregate amount of
the obligations guaranteed hereunder by any Subsidiary Guarantor shall not
exceed the maximum amount that can be hereby guaranteed without rendering this
Indenture, as it relates to any Subsidiary Guarantor, voidable under applicable
law relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

          (b) A Subsidiary Guarantee as to any Subsidiary Guarantor shall
terminate and be of no further force or effect upon the sale (including through
merger or consolidation) of the Capital Stock, or all or substantially all the
assets, of the applicable Subsidiary Guarantor if (a) such sale is made in
compliance with the covenant described under Section 4.06 and (b) such
Subsidiary Guarantor is released from its guarantees of, and all pledges and
security granted in connection with, the Credit Agreement and any other
Indebtedness of Parent, the Company or any Restricted Subsidiary. A Subsidiary
Guarantee also will be automatically released upon the applicable Subsidiary
Guarantor ceasing to be a Subsidiary of the Company as a result of any
foreclosure of any pledge or security interest securing Bank Indebtedness or
other exercise of remedies in respect thereof if such Subsidiary Guarantor is
released from its guarantees of, and all pledges and security interests granted
in connection with, the Credit Agreement.

          SECTION 11.03. SUCCESSORS AND ASSIGNS. This Article 11 shall be
binding upon each Subsidiary Guarantor and its successors and assigns and shall
enure to


<PAGE>   68


                                                                              62

the benefit of the successors and assigns of the Trustee and the Holders and, in
the event of any transfer or assignment of rights by any Holder or the Trustee,
the rights and privileges conferred upon that party in this Indenture and in the
Securities shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions of this Indenture.

          SECTION 11.04. NO WAIVER. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits that either may have under this Article 11 at law,
in equity, by statute or otherwise.

          SECTION 11.05. MODIFICATION. No modification, amendment or waiver of
any provision of this Article 11, nor the consent to any departure by any
Subsidiary Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall
entitle such Subsidiary Guarantor to any other or further notice or demand in
the same, similar or other circumstances.

          SECTION 11.06. EXECUTION OF SUPPLEMENTAL INDENTURE FOR FUTURE
SUBSIDIARY GUARANTORS. (b) Each Subsidiary which is required to become a
Subsidiary Guarantor pursuant to Section 4.11 shall promptly execute and deliver
to the Trustee a supplemental indenture in the form of Exhibit C hereto pursuant
to which such Subsidiary shall become a Subsidiary Guarantor under this Article
11 and shall guarantee the Obligations. Concurrently with the execution and
delivery of such supplemental indenture, the Company shall deliver to the
Trustee an Opinion of Counsel and an Officers' Certificate to the effect that
such supplemental indenture has been duly authorized, executed and delivered by
such Subsidiary and that, subject to the application of bankruptcy, insolvency,
moratorium, fraudulent conveyance or transfer and other similar laws relating to
creditors' rights generally and to the principles of equity, whether considered
in a proceeding at law or in equity, the Subsidiary Guarantee of such Subsidiary
Guarantor is a legal, valid and binding obligation of such Subsidiary Guarantor,
enforceable against such Subsidiary Guarantor in accordance with its terms.



                                   ARTICLE 12

                   SUBORDINATION OF THE SUBSIDIARY GUARANTEES

          SECTION 12.01. AGREEMENT TO SUBORDINATE. Each Subsidiary Guarantor
agrees, and each Securityholder by accepting a Security agrees, that the
Obligations of a Subsidiary Guarantor are subordinated in right of payment, to
the extent and in the manner provided in this Article 12, to the prior payment
in full of all Senior Indebtedness of such Subsidiary Guarantor and that the
subordination is for the benefit of and enforceable by the holders of Senior
Indebtedness of such Subsidiary Guarantor. The Obligations with respect to a
Subsidiary Guarantor shall in all respects rank PARI PASSU with all other Senior
Subordinated Indebtedness of such Subsidiary Guarantor


<PAGE>   69


                                                                              63

(including an Existing Subsidiary Guarantee), and only Indebtedness of such
Subsidiary Guarantor that is Senior Indebtedness of such Subsidiary Guarantor
shall rank senior to the Obligations of such Subsidiary Guarantor in accordance
with the provisions set forth herein.

          SECTION 12.02. LIQUIDATION, DISSOLUTION, BANKRUPTCY. Upon any payment
or distribution of the assets of a Subsidiary Guarantor to creditors upon a
total or partial liquidation or a total or partial dissolution of such
Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to such Subsidiary Guarantor and its
properties:

          (1) holders of Senior Indebtedness of such Subsidiary Guarantor shall
     be entitled to receive payment in full of such Senior Indebtedness before
     Securityholders shall be entitled to receive any payment of any Obligations
     from such Subsidiary Guarantor; and

          (2) until the Senior Indebtedness of such Subsidiary Guarantor is paid
     in full, any payment or distribution to which Securityholders would be
     entitled but for this Article 12 shall be made to holders of such Senior
     Indebtedness as their respective interests may appear.

          SECTION 12.03. DEFAULT ON SENIOR INDEBTEDNESS OF A SUBSIDIARY
GUARANTOR. A Subsidiary Guarantor may not make any payment pursuant to any of
the Obligations or repurchase, redeem or otherwise retire any Securities
(collectively, "pay its Guarantee") if (i) any Senior Indebtedness of such
Subsidiary Guarantor is not paid when due or (ii) any other default on Senior
Indebtedness of such Subsidiary Guarantor occurs and the maturity of such Senior
Indebtedness is accelerated in accordance with its terms unless, in either case,
(x) the default has been cured or waived and any such acceleration has been
rescinded or (y) such Senior Indebtedness has been paid in full; PROVIDED,
HOWEVER, that such Subsidiary Guarantor may pay its Subsidiary Guarantee without
regard to the foregoing if such Subsidiary Guarantor and the Trustee receive
written notice approving such payment from the Representative of the holders of
such Senior Indebtedness with respect to which either of the events in clause
(i) or (ii) of this sentence has occurred and is continuing. During the
continuance of any default (other than a default described in clause (i) or (ii)
of the preceding sentence) with respect to any Designated Senior Indebtedness of
a Subsidiary Guarantor pursuant to which the maturity thereof may be accelerated
immediately without further notice (except such notice as may be required to
effect such acceleration) or the expiration of any applicable grace periods,
such Subsidiary Guarantor may not pay its Guarantee for a period (a "Subsidiary
Guarantor Payment Blockage Period") commencing upon the receipt by the Trustee
(with a copy to such Subsidiary Guarantor and the Company) of written notice (a
"Subsidiary Guarantor Blockage Notice") of such default from the Representative
of the holders of the Designated Senior Indebtedness of such Subsidiary
Guarantor specifying an election to effect a Subsidiary Guarantor Payment
Blockage Period and ending 179 days thereafter (or earlier if such Subsidiary
Guarantor Payment Blockage Period is terminated (i) by written notice to the
Trustee (with a copy to such Subsidiary Guarantor and the Company) from the
Person or Persons who gave such Subsidiary Guarantor Blockage Notice, (ii)
because such Designated Senior Indebtedness has been repaid in full or (iii)
because the default giving rise to such Subsidiary Guarantor Blockage Notice is
no longer continuing). Notwithstanding the provisions described in the
immediately preceding sentence (but subject to the provisions contained in the
first sentence of this


<PAGE>   70


                                                                              64

Section), unless the holders of such Designated Senior Indebtedness or the
Representative of such holders shall have accelerated the maturity of such
Designated Senior Indebtedness, such Subsidiary Guarantor may resume to pay its
Guarantee after such Subsidiary Guarantor Payment Blockage Period, including any
missed payments. Not more than one Subsidiary Guarantor Blockage Notice may be
given with respect to a Subsidiary Guarantor in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness of such Subsidiary Guarantor during such period; PROVIDED, HOWEVER,
that if any Subsidiary Guarantor Blockage Notice within such 360-day period is
given by or on behalf of any holders of Designated Senior Indebtedness of such
Subsidiary Guarantor (other than the Bank Indebtedness), the Representative of
the Bank Indebtedness may give another Subsidiary Guarantor Blockage Notice
within such period; PROVIDED FURTHER, HOWEVER, that in no event may the total
number of days during which any Subsidiary Guarantor Payment Blockage Period or
Periods is in effect exceed 179 days in the aggregate during any 360 consecutive
day period.

          SECTION 12.04. DEMAND FOR PAYMENT. If payment of the Securities is
accelerated because of an Event of Default and a demand for payment is made on a
Subsidiary Guarantor pursuant to Article 11 the Trustee shall promptly notify
the holders of the Designated Senior Indebtedness of such Subsidiary Guarantor
(or the Representative of such holders) of such demand. If any Designated Senior
Indebtedness of such Subsidiary Guarantor is outstanding, such Subsidiary
Guarantor may not pay its Guarantee until five Business Days after such holders
or the Representative of the holders of the Designated Senior Indebtedness of
such Subsidiary Guarantor receive notice of such demand and, thereafter, may pay
its Guarantee only if this Article 12 otherwise permits payment at that time.

          SECTION 12.05. WHEN DISTRIBUTION MUST BE PAID OVER. If a payment or
distribution is made to Securityholders that because of this Article 12 should
not have been made to them, the Securityholders who receive the payment or
distribution shall hold such payment or distribution in trust for holders of the
Senior Indebtedness of the relevant Subsidiary Guarantor and pay it over to them
as their respective interests may appear.

          SECTION 12.06. SUBROGATION. After all Senior Indebtedness of a
Subsidiary Guarantor is paid in full and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of Senior
Indebtedness of such Subsidiary Guarantor to receive distributions applicable to
Senior Indebtedness of such Subsidiary Guarantor. A distribution made under this
Article 12 to holders of Senior Indebtedness of such Subsidiary Guarantor which
otherwise would have been made to Securityholders is not, as between such
Subsidiary Guarantor and Securityholders, a payment by such Subsidiary Guarantor
on Senior Indebtedness of such Subsidiary Guarantor.

          SECTION 12.07. RELATIVE RIGHTS. This Article 12 defines the relative
rights of Securityholders and holders of Senior Indebtedness of a Subsidiary
Guarantor. Nothing in this Indenture shall:

          (1) impair, as between a Subsidiary Guarantor and Securityholders, the
     obligation of a Subsidiary Guarantor that is absolute and unconditional, to
     pay its Obligations to the extent set forth in Article 11; or


<PAGE>   71


                                                                              65

          (2) prevent the Trustee or any Securityholder from exercising its
     available remedies upon a default by a Subsidiary Guarantor under its
     Obligations, subject to the rights of holders of Senior Indebtedness of
     such Subsidiary Guarantor to receive distributions otherwise payable to
     Securityholders.

          SECTION 12.08. SUBORDINATION MAY NOT BE IMPAIRED BY A SUBSIDIARY
GUARANTOR. No right of any holder of Senior Indebtedness of a Subsidiary
Guarantor to enforce the subordination of the Obligations of such Subsidiary
Guarantor shall be impaired by any act or failure to act by such Subsidiary
Guarantor or by its failure to comply with this Indenture.

          SECTION 12.09. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 12.03, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article 12. A Subsidiary Guarantor, the Registrar or co-registrar, the Paying
Agent, a Representative or a holder of Senior Indebtedness of a Subsidiary
Guarantor may give the notice; PROVIDED, HOWEVER, that, if an issue of Senior
Indebtedness of a Subsidiary Guarantor has a Representative, only the
Representative may give the notice. The Trustee shall be entitled to rely on the
delivery to it of a written notice by a Person representing himself or itself to
be a holder of any Senior Indebtedness of a Subsidiary Guarantor (or a
Representative of such holder) to establish that such notice has been given by a
holder of such Senior Indebtedness or Representative thereof.

          The Trustee in its individual or any other capacity may hold Senior
Indebtedness of a Subsidiary Guarantor with the same rights it would have if it
were not Trustee. The Registrar and co-registrar and the Paying Agent may do the
same with like rights. The Trustee shall be entitled to all the rights set forth
in this Article 12 with respect to any Senior Indebtedness of a Subsidiary
Guarantor which may at any time be held by it, to the same extent as any other
holder of Senior Indebtedness of such Subsidiary Guarantor; and nothing in
Article VII shall deprive the Trustee of any of its rights as such holder.
Nothing in this Article 12 shall apply to claims of, or payments to, the Trustee
under or pursuant to Section 7.07.

          SECTION 12.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness
of a Subsidiary Guarantor, the distribution may be made and the notice given to
their Representative (if any).

          SECTION 12.11. ARTICLE 12 NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO ACCELERATE. The failure of a Subsidiary Guarantor to make a payment on
any of its Obligations by reason of any provision in this Article 12 shall not
be construed as pre venting the occurrence of a default by such Subsidiary
Guarantor under its Obligations. Nothing in this Article 12 shall have any
effect on the right of the Securityholders or the Trustee to make a demand for
payment on a Subsidiary Guarantor pursuant to Article 11.

          SECTION 12.12. TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 12, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which


<PAGE>   72


                                                                              66

any proceedings of the nature referred to in Section 12.02 are pending, (ii)
upon a certificate of the liquidating trustee or agent or other Person making
such payment or distribution to the Trustee or to the Securityholders or (iii)
upon the Representatives for the holders of Senior Indebtedness of a Subsidiary
Guarantor for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the holders of the Senior Indebtedness of a
Subsidiary Guarantor and other Indebtedness of a Subsidiary Guarantor, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 12. In the
event that the Trustee determines, in good faith, that evidence is required with
respect to the right of any Person as a holder of Senior Indebtedness of a
Subsidiary Guarantor to participate in any payment or distribution pursuant to
this Article 12, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
of such Subsidiary Guarantor held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this Article 12, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all
actions or omissions of actions by the Trustee pursuant to this Article 12.

          SECTION 12.13. TRUSTEE TO EFFECTUATE SUBORDINATION. Each
Securityholder by accepting a Security authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Senior Indebtedness of each of the Subsidiary Guarantor as provided in this
Article 12 and appoints the Trustee as attorney-in-fact for any and all such
purposes.

          SECTION 12.14. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS OF A SUBSIDIARY GUARANTOR. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness of a Subsidiary
Guarantor and shall not be liable to any such holders if it shall mistakenly pay
over or distribute to Securityholders or the relevant Subsidiary Guarantor or
any other Person, money or assets to which any holders of Senior Indebtedness of
such Subsidiary Guarantor shall be entitled by virtue of this Article 12 or
otherwise.

          SECTION 12.15. RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS OF A
SUBSIDIARY GUARANTOR ON SUBORDINATION PROVISIONS. Each Securityholder by
accepting a Security acknowledges and agrees that the foregoing subordination
provisions are, and are intended to be, an inducement and a consideration to
each holder of any Senior Indebtedness of a Subsidiary Guarantor, whether such
Senior Indebtedness was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such Senior
Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively
to have relied on such subordination provisions in acquiring and continuing to
hold, or in continuing to hold, such Senior Indebtedness.

Holders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities owned by the Company or by any Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company shall be disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities that the Trustee knows are so owned shall be so disregarded. Also,
subject to the foregoing, only Securities outstanding at the time shall be
considered in any such determination.

          SECTION 13.07. RULES BY TRUSTEE, PAYING AGENT AND REGISTRAR. The

Subsidiary Guarantor under the Securities or this Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. By

liability. The waiver and release shall be part of the consideration for the
issue of the Securities.

          SECTION 13.11. SUCCESSORS. All agreements of the Company and each

Securities represented thereby with the Securities Custodian, and registered in

          the form set forth on the reverse side of the Initial Security); or

               (B) if such Definitive Securities are being transferred to the
          Company, a certification to that effect (in the form set forth on the
          reverse side of the Initial Security); or

               (C) if such Definitive Securities are being transferred pursuant
          to an exemption from registration in accordance with Rule 144 under

          counsel or other evidence reasonably satisfactory to it as to the
          compliance with the restrictions set forth in the legend set forth in

          (b) RESTRICTIONS ON TRANSFER OF A DEFINITIVE SECURITY FOR A BENEFICIAL

          (ii) written instructions directing the Trustee to make, or to direct
     the Securities Custodian to make, an adjustment on its books and records
     with respect to such Global Security to reflect an increase in the
     aggregate principal amount of the Securities represented by the Global
     Security, such instructions to contain information regarding the Depositary
     account to be credited with such increase,

then the Trustee shall cancel such Definitive Security and cause, or direct the
Securities Custodian to cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Securities Custodian, the
aggregate principal amount of Securities represented by the Global Security to
be increased by the aggregate principal amount of the Definitive Security to be

form of an Officers' Certificate, a new Global Security in the appropriate
principal amount.

          (c) TRANSFER AND EXCHANGE OF GLOBAL SECURITIES. (i) The transfer and
exchange of Global Securities or beneficial interests therein shall be effected
through the Depositary, in accordance with this Indenture (including applicable
restrictions on transfer set forth herein, if any) and the procedures of the
Depositary therefor. A transferor of a beneficial interest in a Global Security
shall deliver a written order given in accordance with the Depositary's
procedures containing information regarding the participant account of the
Depositary to be credited with a beneficial interest in such Global Security or
another Global Security and such account shall be credited in accordance with
such order with a beneficial interest in the applicable Global Security and the
account of the Person making the transfer shall be debited by an amount equal to
the beneficial interest in the Global Security being transferred. Transfers by
an owner of a beneficial interest in the Rule 144A Global Security or the IAI
Global Security to a transferee who takes delivery of such interest through the
Regulation S Global Security, whether before or after the expiration of the
Restricted Period, shall be made only upon receipt by the Trustee of a
certification from the transferor to the effect that such transfer is being made
in accordance with Regulation S or (if available) Rule 144 under the Securities
Act and that, if such transfer is being made prior to the expiration of the
Restricted Period, the interest transferred shall be held immediately thereafter
through Euroclear or Cedel. In the case of a transfer of a beneficial interest
in either the Regulation S Global Security or the Rule 144A Global Security for
an interest in the IAI Global Security, the transferee must furnish a signed
letter substantially in the form of Exhibit D to the Trustee.

          (ii) If the proposed transfer is a transfer of a beneficial interest
     in one Global Security to a beneficial interest in another Global Security,
     the Registrar shall reflect on its books and records the date and an
     increase in the principal amount of the Global Security to which such
     interest is being transferred in an amount equal to the principal amount of
     the interest to be so transferred, and the Registrar shall reflect on its
     books and records the date and a corresponding decrease in the principal
     amount of Global Security from which such interest is being transferred.

          (iii) Notwithstanding any other provisions of this Appendix (other
     than the provisions set forth in Section 2.4), a Global Security may not be
     transferred as a whole except by the Depositary to a nominee of the
     Depositary or by a nominee of the Depositary to the Depositary or another
     nominee of the Depositary or by the Depositary or any such nominee to a
     successor Depositary or a nominee of such successor Depositary.

          (iv) In the event that a Global Security is exchanged for Definitive
     Securities pursuant to Section 2.4 prior to the consummation of the
     Registered Exchange Offer or the effectiveness of the Shelf Registration
     Statement with respect to such Securities, such Securities may be exchanged
     only in accordance with such procedures as are substantially consistent
     with the provisions of this Section 2.3 (including the certification
     requirements set forth on the reverse of the Initial Securities intended to
     ensure that such transfers comply with Rule 144A, Regulation S or such
     other applicable exemption from registration under the

                                                                               7

     Securities Act, as the case may be) and such other procedures as may from
     time to time be adopted by the Company.

          (d) RESTRICTIONS ON TRANSFER OF REGULATION S GLOBAL SECURITY. (i)
Prior to the expiration of the Restricted Period, interests in the Regulation S
Global Security may only be held through Euroclear or Cedel. During the
Restricted Period, beneficial ownership interests in the Regulation S Global
Security may only be sold, pledged or transferred through Euroclear or Cedel in
accordance with the Applicable Procedures and only (A) to the Company, (B) so
long as such security is eligible for resale pursuant to Rule 144A, to a person
whom the selling holder reasonably believes is a QIB that purchases for its own
account or for the account of a QIB to whom notice is given that the resale,
pledge or transfer is being made in reliance on Rule 144A, (C) in an offshore
transaction in accordance with Regulation S, (D) pursuant to an exemption from
registration under the Securities Act provided by Rule 144 (if applicable) under
the Securities Act, (E) to an IAI purchasing for its own account, or for the
account of such an IAI, in a minimum principal amount of Securities of $250,000
or (F) pursuant to an effective registration statement under the Securities Act,
in each case in accordance with any applicable securities laws of any state of
the United States. Prior to the expiration of the Restricted Period, transfers
by an owner of a beneficial interest in the Regulation S Global Security to a
transferee who takes delivery of such interest through the Rule 144A Global
Security or the IAI Global Security shall be made only in accordance with
Applicable Procedures and upon receipt by the Trustee of a written certification
from the transferor of the beneficial interest in the form provided on the
reverse of the Initial Security to the effect that such transfer is being made
to (i) a person whom the transferor reasonably believes is a QIB within the
meaning of Rule 144A in a transaction meeting the requirements of Rule 144A or
(ii) an IAI purchasing for its own account, or for the account of such an IAI,
in a minimum principal amount of the Securities of $250,000. Such written
certification shall no longer be required after the expiration of the Restricted
Period. In the case of a transfer of a beneficial interest in the Regulation S
Global Security for an interest in the IAI Global Security, the transferee must
furnish a signed letter substantially in the form of Exhibit D to the Trustee.

          (ii) Upon the expiration of the Restricted Period, beneficial
     ownership interests in the Regulation S Global Security shall be
     transferable in accordance with applicable law and the other terms of this
     Indenture.

          (e) LEGEND.

          (i) Except as permitted by the following paragraphs (ii), (iii) or
     (iv), each Security certificate evidencing the Global Securities and the

          (ii) Upon any sale or transfer of a Transfer Restricted Security that
     is a Definitive Security, the Registrar shall permit the Holder thereof to
     exchange such Transfer Restricted Security for a Definitive Security that
     does not bear the legends set forth above and rescind any restriction on
     the transfer of such Transfer Restricted Security if the Holder certifies
     in writing to the Registrar that its request for such exchange was made in
     reliance on Rule 144 (such certification to be in the form set forth on the
     reverse of the Initial Security).

          (iii) After a transfer of any Initial Securities or Private Exchange
     Securities during the period of the effectiveness of a Shelf Registration

     Securities, as the case may be, all requirements pertaining to the
     Restricted Securities Legend on such Initial Securities or such Private
     Exchange Securities shall cease to apply and the requirements that any such
     Initial Securities or such Private Exchange Securities be issued in global
     form shall continue to apply.

          (iv) Upon the consummation of a Registered Exchange Offer with respect
     to the Initial Securities pursuant to which Holders of such Initial
     Securities are offered Exchange Securities in exchange for their Initial
     Securities, all requirements pertaining to Initial Securities that Initial
     Securities be issued in global form shall continue to apply, and Exchange
     Securities in global form without the Restricted Securities Legend shall be
     available to Holders that exchange such Initial Securities in such
     Registered Exchange Offer.

          (v) Upon the consummation of a Private Exchange with respect to the
     Initial Securities pursuant to which Holders of such Initial Securities are
     offered Private Exchange Securities in exchange for their Initial

          (f) CANCELATION OR ADJUSTMENT OF GLOBAL SECURITY. At such time as all
beneficial interests in a Global Security have either been exchanged for
Definitive Securities, transferred, redeemed, repurchased or canceled, such
Global Security shall be returned by the Depositary to the Trustee for
cancelation or retained and canceled by the Trustee. At any time prior to such
cancelation, if any beneficial interest in a Global Security is exchanged for
Definitive Securities, transferred in exchange for an interest in another Global
Security, redeemed, repurchased or canceled, the principal amount of Securities
represented by such Global Security shall be reduced and an adjustment shall be
made on the books and records of the Trustee (if it is then the Securities
Custodian for such Global Security) with respect to such Global Security, by the
Trustee or the Securities Custodian, to reflect such reduction.

     the Holders and all payments to be made to Holders under the Securities

                8 5/8% Senior Subordinated Note due 2007, Series C


1.  INTEREST

          ARGO-TECH CORPORATION, a Delaware corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), promises to pay interest on the principal amount
of this Security at the rate per annum shown above. The Company and the
Subsidiary Guarantors will use their best efforts to have the Exchange Offer
Registration Statement or, if applicable, the Shelf Registration Statement (each
a "Registration Statement") declared effective by the Commission as promptly as
practicable after the filing thereof. If (i) the Shelf Registration Statement or
Exchange Offer Registration Statement, as applicable under the Exchange and
Registration Rights Agreement is not filed with the Commission on or prior to 75
days after the Issue Date, (ii) the Exchange Offer Registration Statement or, as
the case may be, the Shelf Registration Statement, is not declared effective
within 135 days after the Issue Date, (iii) the Exchange Offer is not
consummated on or prior to 165 days after the Issue Date, or (iv) the Shelf
Registration Statement is filed and declared effective within 135 days after the
Issue Date but shall thereafter cease to be effective (at any time that the
Company is obligated to maintain the effectiveness thereof) without being
succeeded within 30 days by an additional Registration Statement filed and
declared effective (each such event referred to in clauses (i) through (iv), a
"Registration Default"), the Company will pay liquidated damages to each holder
of Transfer Restricted Securities, during the period of such Registration
Default, in an amount equal to $0.192 per week per $1,000 principal amount of
the Securities constituting Transfer Restricted Securities held by such holder
until the applicable Registration Statement is filed or declared effective, the
Exchange Offer is consummated or the Shelf Registration Statement again becomes
effective, as the case may be. All accrued liquidated damages shall be paid to
holders in the same manner as interest payments on the Securities on semi-annual
payment dates which correspond to interest payment dates for the Securities.
Following the cure of all Registration Defaults, the accrual of liquidated
damages will cease. The Trustee shall have no responsibility with respect to the
determination of the amount of any such liquidated damages. For purposes of the
foregoing, "Transfer Restricted Securities" means (i) each Initial Security
until the date on which such Initial Security has been exchanged for a freely
transferable Exchange Security in the Exchange Offer, (ii) each Initial Security
or Private Exchange Security until the date on which such Initial Security or
Private Exchange Security has been effectively registered under the Securities
Act and disposed of in accordance with the Shelf Registration Statement or (iii)
each Initial Security or Private Exchange Security until the date on which such
Initial Security or Private Exchange Security is distributed to the public
pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule
144(k) under the Securities Act.

          The Company will pay interest and liquidated damages, if any,
semiannually on April 1 and October 1 of each year. Interest on the Securities
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from December 17, 1998. Interest will be computed on the
basis of a 360-day year of twelve 30-day months. The Company shall pay interest
on overdue principal at

                                                                               6

the rate borne by the Securities plus 1% per annum, and it shall pay interest on
overdue installments of interest at the same rate to the extent lawful.


2.  METHOD OF PAYMENT

          The Company will pay interest (except defaulted interest) on and
liquidated damages, if any, in respect of the Securities to the Persons who are
registered holders of Securities at the close of business on the March 15 or
September 15 next preceding the interest payment date even if Securities are
canceled after the record date and on or before the interest payment date.
Holders must surrender Securities 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. However, the Company may pay principal and interest by check
payable in such money or by wire transfer of federal funds.


3.  PAYING AGENT AND REGISTRAR

          Initially, HARRIS TRUST AND SAVINGS BANK, an Illinois banking
corporation ("Trustee"), will act as Paying Agent and Registrar. The Company may
appoint and change any Paying Agent, Registrar or co-registrar without notice to
the Holders. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.


4.  INDENTURE

          The Company issued the Securities under an Indenture dated as of
December 17, 1998 ("Indenture"), among the Company, the Subsidiary Guarantors
and the Trustee. The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. sections 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Terms defined in the Indenture and not defined
herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and
the Act for a statement of those terms.

          The Securities are unsecured senior subordinated obligations of the
Company limited to $55,000,000 aggregate principal amount at any one time
outstanding (subject to Section 2.07 of the Indenture). This Security is one of
the Initial Securities referred to in the Indenture. The Securities include the
Initial Securities and any Exchange Securities and Private Exchange Securities
issued in exchange for the Initial Securities pursuant to the Indenture. The
Initial Securities, the Exchange Securities and the Private Exchange Securities
are treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the Incurrence of Indebtedness by the Company and
its Restricted Subsidiaries; the payment of dividends on, and redemption of,
Capital Stock of the Company and its Restricted Subsidiaries and the redemption
of certain Subordinated Obligations of the Company and its Restricted
Subsidiaries; Investments; sales of assets and Restricted Subsidiary Capital
Stock; certain transactions with Affiliates of the Company; the sale or issuance
of Capital Stock of the Restricted Subsidiaries; the creation of Liens; the
lines of business in which the Company

                                                                               7

and its Restricted Subsidiaries may operate; Sale/Leaseback Transactions and
consolidations, mergers and transfers of all or substantially all of the
Company's assets. In addition, the Indenture prohibits certain restrictions on
distributions and dividends from Restricted Subsidiaries.

          To guarantee the due and punctual payment of the principal and
interest, if any, on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
guaranteed the Company's obligations under the Indenture on a senior
subordinated basis pursuant to the terms of the Indenture.

amount), plus accrued and unpaid interest, if any, to the redemption date
(subject to the right of Holders of record on the relevant record date to

PROVIDED, HOWEVER, that at least 66 2/3% of the original aggregate principal
amount of the Securities must remain outstanding after each such redemption.

          (c) Notwithstanding paragraphs (a) and (b) above, the Company shall
not redeem any Securities, other than pursuant to paragraph 6 below, unless,
substantially concurrently with such redemption, the Company redeems an
aggregate principal amount of Existing Securities (rounded to the nearest
integral multiple of $1,000) equal to the product of: (1) a fraction, the
numerator of which is the aggregate principal amount of Securities to be so
redeemed and the denominator of which is the aggregate principal amount of
Securities outstanding immediately prior to such proposed redemption, and

                                                                               8

(2) the aggregate principal amount of Existing Securities outstanding
immediately prior to such proposed redemption. The Company shall not redeem the
Existing Securities unless, substantially concurrently with such redemption, the
Company redeems an aggregate principal amount of each series of Securities
(rounded to the nearest integral multiple of $1,000) equal to the product of:
(1) a fraction, the numerator of which is the aggregate principal amount of
Existing Securities to be so redeemed and the denominator of which is the
aggregate principal amount of Existing Securities outstanding immediately prior
to such proposed redemption, and (2) the aggregate principal amount of such
series of Securities outstanding immediately prior to such proposed redemption.

          (d) Notice of optional redemption will be mailed by first-class mail
at least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his registered address. Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

6.  MANDATORY REDEMPTION

          (a) Notwithstanding the foregoing, in the event that the Stock
Repurchase is not consummated prior to January 15, 1999, the Company shall

          (b) Notice of redemption will be transmitted by overnight mail or
facsimile one day before the redemption date to each Holder of Securities to be

7.  PUT PROVISIONS

          Upon a Change of Control, unless the Company has elected to redeem the
Securities pursuant to paragraph 5, any Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of the Securities of such Holder at a
purchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date that is on or prior
to the date of purchase) as provided in, and subject to the terms of, the
Indenture.


8.  SUBORDINATION

          The Securities are subordinated to Senior Indebtedness of the Company,

Indebtedness of the Company must be paid before the Securities may be paid. In
addition, each Subsidiary Guarantee is subordinated to Senior Indebtedness of
the relevant Subsidiary Guarantor, as defined in the Indenture. The Company and
each Subsidiary Guarantor agrees, and each Securityholder by accepting a
Security agrees, to the subordination

                                                                               9

provisions contained in the Indenture and authorizes the Trustee to give it

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture. The Registrar need not register the transfer
of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or to transfer or exchange any Securities for a period of 15 days prior to a
selection of Securities to be redeemed or 15 days before an interest payment
date.


10.  PERSONS DEEMED OWNERS

          The registered Holder of this Security may be treated as the owner of
it for all purposes.


11.  UNCLAIMED MONEY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.


12.  DISCHARGE AND DEFEASANCE

          Subject to certain conditions, the Company at any time may terminate
some or all of its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be. The Company shall not exercise its option to defease the
Securities unless it defeases the Original Securities equivalently and
substantially simultaneously, and the Company shall not exercise its option to
defease the Original Securities unless it defeases the Securities equivalently
and substantially simultaneously.


13.  AMENDMENT, WAIVER

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any past default or noncompliance with any provision may be waived with
the consent of the Holders of a


<PAGE>   98

majority in principal amount then outstanding of the Securities. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article V of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities or to secure the Securities, or to
release Subsidiary Guarantors when permitted by the Indenture, or to add
additional covenants or surrender rights and powers conferred on the Company, or
to comply with any request of the SEC in connection with qualifying the
Indenture under the Act, or to make any other change that does not adversely
affect the rights of any Securityholder, or to provide for the issuance and
authorization of the Exchange Securities or Private Exchange Securities.


14.  DEFAULTS AND REMEDIES

          Under the Indenture, Events of Default include (i) default for 30 days
in payment of interest on the Securities; (ii) default in payment of principal
on the Securities at maturity, upon redemption pursuant to paragraph 5 of the
Securities, or failure by the Company to redeem or purchase, upon declaration or
otherwise (whether or not such payment is prohibited by Article X), Securities
when required; (iii) failure by the Company or any Subsidiary Guarantor to
comply with other agreements in the Indenture or the Securities, in certain
cases subject to notice and lapse of time; (iv) certain accelerations (including
failure to pay within any grace period after final maturity) of other
Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds
$5,000,000 or its foreign currency equivalent; (v) certain events of bankruptcy,
insolvency or reorganization with respect to the Company and its Restricted
Subsidiaries; (vi) certain judgments or decrees not covered by insurance for the
payment of money in excess of $5,000,000 or its foreign currency equivalent
against the Company or a Restricted Subsidiary; and (vii) a Subsidiary Guarantee
ceasing to be in full force and effect (other than in accordance with its terms)
or any Subsidiary Guarantor denies or disaffirms its obligations under the
Indenture or any Subsidiary Guarantee and such Default continues for 10 days. If
an Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the Securities may declare all the Securities
to be due and payable immediately. Certain events of bankruptcy or insolvency
are Events of Default which will result in the Securities being due and payable
immediately upon the occurrence of such Events of Default.

          Securityholders may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default (except a Default
in payment of principal, premium, if any, or interest) if and so long as a
committee of its Trust Officers in good faith determines that withholding notice
is in the interest of the Holders.

15.  TRUSTEE DEALINGS WITH THE COMPANY

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.


16.  NO RECOURSE AGAINST OTHERS

          A director, officer, employee or stockholder, as such, of the Company
or any Subsidiary Guarantor shall not have any liability for any obligations of
the Company or a Subsidiary Guarantor under the Securities or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Securities.


17.      GOVERNING LAW

          THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK, BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

Security Identification Procedures the Company has caused CUSIP numbers to be

                8 5/8% Senior Subordinated Note due 2007, Series C


1.  INTEREST.

          ARGO-TECH CORPORATION, a Delaware corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), promises to pay interest on the principal amount
of this Security at the rate per annum shown above. The Company shall pay
interest semiannually on April 1 and October 1 of each year. Interest on the
Securities shall accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from December 17, 1998. Interest shall be
computed on the basis of a 360-day year of twelve 30-day months. The Company
shall pay interest on overdue principal at the rate borne by the Securities plus
1% per annum, and it shall pay interest on overdue installments of interest at
the same rate to the extent lawful.

2.  METHOD OF PAYMENT

          The Company will pay interest (except defaulted interest) on and
liquidated damages, if any, in respect of the Securities to the Persons who are
registered holders of Securities at the close of business on the March 15 or
September 15 next preceding the interest payment date even if Securities are
canceled after the record date and on or before the interest payment date.
Holders must surrender Securities 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. However, the Company may pay principal and interest by check
payable in such money or by wire transfer of federal funds.


3.  PAYING AGENT AND REGISTRAR

          Initially, HARRIS TRUST AND SAVINGS BANK, an Illinois banking
corporation ("Trustee"), will act as Paying Agent and Registrar. The Company may
appoint and change any Paying Agent, Registrar or co-registrar without notice to
the Holders. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.


4.  INDENTURE

          The Company issued the Securities under an Indenture dated as of
December 17, 1998 ("Indenture"), among the Company, the Subsidiary Guarantors
and the Trustee. The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. sections 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Terms defined in the Indenture and not defined
herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and
the Act for a statement of those terms.



<PAGE>   109


                                                                               4

          The Securities are unsecured senior subordinated obligations of the
Company limited to $55,000,000 aggregate principal amount at any one time
outstanding (subject to Section 2.07 of the Indenture). This Security is one of
the Initial Securities referred to in the Indenture. The Securities include the
Initial Securities and any Exchange Securities and Private Exchange Securities
issued in exchange for the Initial Securities pursuant to the Indenture. The
Initial Securities, the Exchange Securities and the Private Exchange Securities
are treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the Incurrence of Indebtedness by the Company and
its Restricted Subsidiaries; the payment of dividends on, and redemption of,
Capital Stock of the Company and its Restricted Subsidiaries and the redemption
of certain Subordinated Obligations of the Company and its Restricted
Subsidiaries; Investments; sales of assets and Restricted Subsidiary Capital
Stock; certain transactions with Affiliates of the Company; the sale or issuance
of Capital Stock of the Restricted Subsidiaries; the creation of Liens; the
lines of business in which the Company and its Restricted Subsidiaries may
operate; Sale/Leaseback Transactions and consolidations, mergers and transfers
of all or substantially all of the Company's assets. In addition, the Indenture
prohibits certain restrictions on distributions and dividends from Restricted
Subsidiaries.

          To guarantee the due and punctual payment of the principal and
interest, if any, on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
guaranteed the Company's obligations under the Indenture on a senior
subordinated basis pursuant to the terms of the Indenture.

5. OPTIONAL REDEMPTION

          (a) Except as set forth in the next two paragraphs and paragraph 6
below, the Securities may not be redeemed prior to October 1, 2002. On and after
that date, the Company may redeem the Securities in whole or in part, at any
time at the following redemption prices (expressed in percentages of principal
amount), plus accrued and unpaid interest, if any, to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date that is on or prior
to the date of redemption), if redeemed during the 12-month period beginning on
or after October 1 of the years set forth below:

          (b) Notwithstanding the foregoing, at any time on or prior to October
1, 2000, the Company may redeem in the aggregate up to 33 1/3% of the original
aggregate principal amount of Securities with the proceeds of one or more Public
Equity Offerings following which there is a Public Market, at a redemption price
(expressed as a percentage of principal amount thereof) of 108.625% plus accrued
and unpaid interest, if

                                                                               5

any, to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date that is on or prior to the date of redemption); PROVIDED, HOWEVER, that at
least 66 2/3% of the original aggregate principal amount of the Securities must
remain outstanding after each such redemption.

          (c) Notwithstanding paragraphs (a) and (b) above, the Company shall
not redeem any Securities, other than pursuant to paragraph 6 below, unless,
substantially concurrently with such redemption, the Company redeems an
aggregate principal amount of Existing Securities (rounded to the nearest
integral multiple of $1,000) equal to the product of: (1) a fraction, the
numerator of which is the aggregate principal amount of Securities to be so
redeemed and the denominator of which is the aggregate principal amount of
Securities outstanding immediately prior to such proposed redemption, and (2)
the aggregate principal amount of Existing Securities outstanding immediately
prior to such proposed redemption. The Company shall not redeem the Existing
Securities unless, substantially concurrently with such redemption, the Company
redeems an aggregate principal amount of each series of Securities (rounded to
the nearest integral multiple of $1,000) equal to the product of: (1) a
fraction, the numerator of which is the aggregate principal amount of Existing
Securities to be so redeemed and the denominator of which is the aggregate
principal amount of Existing Securities outstanding immediately prior to such
proposed redemption, and (2) the aggregate principal amount of such series of
Securities outstanding immediately prior to such proposed redemption.

          (d) Notice of optional redemption will be mailed by first-class mail
at least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his registered address. Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

6.  MANDATORY REDEMPTION

          (a) Notwithstanding the foregoing, in the event that the Stock
Repurchase is not consummated prior to January 15, 1999, the Company shall
redeem the Securities in whole on January 15, 1999, at a redemption price
(expressed as a percentage of principal amount) of 96.0%, plus accrued and
unpaid interest to the redemption date.

          (b) Notice of redemption will be transmitted by overnight mail or
facsimile one day before the redemption date to each Holder of Securities to be
redeemed.

7.  PUT PROVISIONS

          Upon a Change of Control, unless the Company has elected to redeem the
Securities pursuant to paragraph 5, any Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of the Securities of such Holder at a
purchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest, if


<PAGE>   111


                                                                               6

any, to the date of purchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date that is on or prior to the date of purchase) as provided in, and subject to
the terms of, the Indenture.


8.  SUBORDINATION

          The Securities are subordinated to Senior Indebtedness of the Company,
as defined in the Indenture. To the extent provided in the Indenture, Senior
Indebtedness of the Company must be paid before the Securities may be paid. In
addition, each Subsidiary Guarantee is subordinated to Senior Indebtedness of
the relevant Subsidiary Guarantor, as defined in the Indenture. The Company and
each Subsidiary Guarantor agrees, and each Securityholder by accepting a
Security agrees, to the subordination provisions contained in the Indenture and
authorizes the Trustee to give it effect and appoints the Trustee as
attorney-in-fact for such purpose.


9.  DENOMINATIONS; TRANSFER; EXCHANGE

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by
law or permitted by the Indenture. The Registrar need not register the transfer
of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or to transfer or exchange any Securities for a period of 15 days prior to a
selection of Securities to be redeemed or 15 days before an interest payment
date.


10.  PERSONS DEEMED OWNERS

          The registered Holder of this Security may be treated as the owner of
it for all purposes.


11.  UNCLAIMED MONEY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.


12.  DISCHARGE AND DEFEASANCE

          Subject to certain conditions, the Company at any time may terminate
some or all of its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of


<PAGE>   112


                                                                               7

principal and interest on the Securities to redemption or maturity, as the case
may be. The Company shall not exercise its option to defease the Securities
unless it defeases the Original Securities equivalently and substantially
simultaneously, and the Company shall not exercise its option to defease the
Original Securities unless it defeases the Securities equivalently and
substantially simultaneously.


13.  AMENDMENT, WAIVER

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any past default or noncompliance with any provision may be waived with
the consent of the Holders of a majority in principal amount then outstanding of
the Securities. Subject to certain exceptions set forth in the Indenture,
without the consent of any Securityholder, the Company and the Trustee may amend
the Indenture or the Securities to cure any ambiguity, omission, defect or
inconsistency, or to comply with Article V of the Indenture, or to provide for
uncertificated Securities in addition to or in place of certificated Securities,
or to add guarantees with respect to the Securities or to secure the Securities,
or to release Subsidiary Guarantors when permitted by the Indenture, or to add
additional covenants or surrender rights and powers conferred on the Company, or
to comply with any request of the SEC in connection with qualifying the
Indenture under the Act, or to make any other change that does not adversely
affect the rights of any Securityholder, or to provide for the issuance and
authorization of the Exchange Securities or Private Exchange Securities.


14.  DEFAULTS AND REMEDIES

          Under the Indenture, Events of Default include (i) default for 30 days
in payment of interest on the Securities; (ii) default in payment of principal
on the Securities at maturity, upon redemption pursuant to paragraph 5 of the
Securities, or failure by the Company to redeem or purchase, upon declaration or
otherwise (whether or not such payment is prohibited by Article X), Securities
when required; (iii) failure by the Company or any Subsidiary Guarantor to
comply with other agreements in the Indenture or the Securities, in certain
cases subject to notice and lapse of time; (iv) certain accelerations (including
failure to pay within any grace period after final maturity) of other
Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds
$5,000,000 or its foreign currency equivalent; (v) certain events of bankruptcy,
insolvency or reorganization with respect to the Company and its Restricted
Subsidiaries; (vi) certain judgments or decrees not covered by insurance for the
payment of money in excess of $5,000,000 or its foreign currency equivalent
against the Company or a Restricted Subsidiary; and (vii) a Subsidiary Guarantee
ceasing to be in full force and effect (other than in accordance with its terms)
or any Subsidiary Guarantor denies or disaffirms its obligations under the
Indenture or any Subsidiary Guarantee and such Default continues for 10 days. If
an Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the Securities may declare all the Securities
to be due and payable immediately. Certain events of bankruptcy or insolvency
are Events of Default which will result in the Securities being due and payable

          Securityholders may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default (except a Default
in payment of principal, premium, if any, or interest) if and so long as a
committee of its Trust Officers in good faith determines that withholding notice
is in the interest of the Holders.


15.  TRUSTEE DEALINGS WITH THE COMPANY

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.


16.  NO RECOURSE AGAINST OTHERS

          A director, officer, employee or stockholder, as such, of the Company
or any Subsidiary Guarantor shall not have any liability for any obligations of
the Company or a Subsidiary Guarantor under the Securities or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Securities.


17.  GOVERNING LAW

          THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK, BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.


18.  AUTHENTICATION

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.


19.  ABBREVIATIONS

          Customary abbreviations may be used in the name of a Securityholder or
an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.  CUSIP NUMBERS

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

Name:____________________________

         The undersigned represents and warrants to you that:

         1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the

or sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Securities,
and we invest in or purchase securities similar to the Securities in the normal
course of our business. We, and any accounts for which we are acting, are each
able to bear the economic risk of our or its investment.

         2. We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence. We agree on our own behalf and on behalf of any investor
account for which we are purchasing Securities to offer, sell or otherwise
transfer such Securities prior to the date that is two years after the later of
the date of original issue and the last date on which the Company or any
affiliate of the Company was the owner of such Securities (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to the Company,

institutional buyer under Rule 144A (a "QIB") that is purchasing for its own
account or for the account of a QIB and to whom notice is given that the
transfer is being made in reliance on Rule 144A, (d) pursuant to offers and
sales that occur outside the United States within the meaning of Regulation S
under the Securities Act, (e) to an institutional "accredited investor" within
the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is
purchasing for its own account or for the account of such an institutional
"accredited investor," in each case in a minimum principal amount of Securities
of $250,000, or (f) pursuant to any other available exemption from the
registration requirements of the Securities Act, subject in each of the
foregoing cases to any requirement of law that the disposition of our property
or the property of such investor account or accounts be at all times within our
or their control and in compliance with any applicable state securities laws.
The foregoing restrictions on resale will not apply subsequent to the Resale
Restriction Termination Date. If any resale or other transfer of the Securities
is proposed to be made pursuant to clause (e) above prior to the Resale
Restriction Termination Date, the transferor shall deliver a letter from the
transferee substantially in the form of this letter to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act and that it is acquiring such Securities for
investment purposes and not for distribution in violation of the Securities Act.
Each purchaser acknowledges that the Company and the Trustee reserve the right
prior to the offer, sale or other transfer prior to the Resale Restriction
Termination Date of the Securities pursuant to clause (d), (e) or (f) above to
require the delivery of an opinion of counsel, certifications or other
information satisfactory to the Company and the Trustee.

transfer restrictions relating to the Securities, (ii) use their reasonable best
efforts to cause the Exchange Offer Registration Statement to become effective
under the Securities Act no later than 135 days after the Issue Date and the
Registered Exchange Offer to be consummated no later than 165 days after the
Issue Date and (iii) keep the Exchange Offer Registration Statement effective
for not less than 30 days (or longer, if required by applicable law) after the
date on which notice of the Registered Exchange Offer is mailed to the Holders
(such period being called the "Exchange Offer Registration Period"). The
Exchange Securities will be issued under the Indenture or an indenture (the
"Exchange Securities Indenture") among the Company, the Subsidiary Guarantors
and the Trustee or such other bank or trust company that is reasonably
satisfactory to the Initial Purchaser, as trustee (the "Exchange Securities
Trustee"), such indenture to be identical in all material respects to the
Indenture, except for the transfer restrictions relating to the Securities (as
described above).

                  Upon the effectiveness of the Exchange Offer Registration
Statement, the Company shall promptly commence the Registered Exchange Offer, it
being the objective of such Registered Exchange Offer to enable each Holder
electing to exchange Securities for Exchange Securities (assuming that such
Holder (a) is not an affiliate of the Company or an Exchanging Dealer (as
defined herein) not complying with the requirements of the next sentence, (b) is
not the Initial Purchaser holding Securities that have, or that are reasonably
likely to have, the status of an

                                                                               2

unsold allotment in an initial distribution, (c) acquires the Exchange
Securities in the ordinary course of such Holder's business and (d) has no
arrangements or understandings with any person to participate in the
distribution of the Exchange Securities) and to trade such Exchange Securities
from and after their receipt without any limitations or restrictions under the
Securities Act and without material restrictions under the securities laws of
the several states of the United States. The Company, the Subsidiary Guarantors,
the Initial Purchaser and each Exchanging Dealer acknowledge that, pursuant to
current interpretations by the Commission's staff of Section 5 of the Securities
Act, each Holder that is a broker-dealer electing to exchange Securities,
acquired for its own account as a result of market-making activities or other
trading activities, for Exchange Securities (an "Exchanging Dealer"), is
required to deliver a prospectus containing substantially the information set
forth in Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer
Procedures" section and the "Purpose of the Exchange Offer" section and in Annex
C hereto in the "Plan of Distribution" section of such prospectus in connection
with a sale of any such Exchange Securities received by such Exchanging Dealer
pursuant to the Registered Exchange Offer.

                  If, prior to the consummation of the Registered Exchange
Offer, any Holder holds any Securities acquired by it that have, or that are
reasonably likely to be determined to have, the status of an unsold allotment in
an initial distribution, or any Holder is not entitled to participate in the
Registered Exchange Offer, the Company shall, upon the request of any such
Holder, simultaneously with the delivery of the Exchange Securities in the
Registered Exchange Offer, issue and deliver to any such Holder, in exchange for
the Securities held by such Holder (the "Private Exchange"), a like aggregate
principal amount of debt securities of the Company (the "Private Exchange
Securities") that are identical in all material respects to the Exchange
Securities, except for the transfer restrictions relating to such Private
Exchange Securities. The Private Exchange Securities will be issued under the
same indenture as the Exchange Securities, and the Company shall use its
reasonable best efforts to cause the Private Exchange Securities to bear the
same CUSIP number as the Exchange Securities.

                  In connection with the Registered Exchange Offer, the Company
shall:

                  (a) mail to each Holder a copy of the prospectus forming part
         of the Exchange Offer Registration Statement, together with an
         appropriate letter of transmittal and related documents;

                  (b) keep the Registered Exchange Offer open for not less than
         30 days (or longer, if required by applicable law) after the date on
         which notice of the Registered Exchange Offer is mailed to the Holders;

                  (c) utilize the services of a depositary for the Registered
         Exchange Offer with an address in the Borough of Manhattan, The City of
         New York;

                  (d) permit Holders to withdraw tendered Securities at any time
         prior to the close of business, New York City time, on the last
         business day on which the Registered Exchange Offer shall remain open;
         and

                  (e) otherwise comply in all respects with all laws that are
         applicable to the Registered Exchange Offer.

                  As soon as practicable after the close of the Registered
Exchange Offer and any Private Exchange, as the case may be, the Company shall:

                  (a) accept for exchange all Securities tendered and not
         validly withdrawn pursuant to the Registered Exchange Offer and the
         Private Exchange;

                  (b) deliver to the Trustee for cancelation all Securities so
         accepted for exchange; and


<PAGE>   3


                                                                               3

                  (c) cause the Trustee or the Exchange Securities Trustee, as
         the case may be, promptly to authenticate and deliver to each Holder,
         Exchange Securities or Private Exchange Securities, as the case may be,
         equal in principal amount to the Securities of such Holder so accepted
         for exchange.

                  The Company shall use its reasonable best efforts to keep the
Exchange Offer Registration Statement effective and to amend and supplement the
prospectus contained therein in order to permit such prospectus to be used by
all persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such persons must comply with such requirements
in order to resell the Exchange Securities; provided that (i) in the case where
such prospectus and any amendment or supplement thereto must be delivered by an
Exchanging Dealer, such period shall be the lesser of 180 days and the date on
which all Exchanging Dealers have sold all Exchange Securities held by them and
(ii) the Company shall make such prospectus and any amendment or supplement
thereto available to any broker-dealer for use in connection with any resale of
any Exchange Securities for a period of not less than 90 days after the
consummation of the Registered Exchange Offer.

                  The Indenture or the Exchange Securities Indenture, as the
case may be, shall provide that the Securities, the Exchange Securities and the
Private Exchange Securities shall vote and consent together on all matters as
one class and that none of the Securities, the Exchange Securities or the
Private Exchange Securities will have the right to vote or consent as a separate
class on any matter.

                  Interest on each Exchange Security and Private Exchange
Security issued pursuant to the Registered Exchange Offer and in the Private
Exchange will accrue from the last interest payment date on which interest was
paid on the Securities surrendered in exchange therefor or, if no interest has
been paid on the Securities, from the Issue Date.

                  Each Holder participating in the Registered Exchange Offer
shall be required to represent to the Company that at the time of the
consummation of the Registered Exchange Offer (i) any Exchange Securities
received by such Holder will be acquired in the ordinary course of business,
(ii) such Holder will have no arrangements or understanding with any person to
participate in the distribution of the Securities or the Exchange Securities
within the meaning of the Securities Act and (iii) such Holder is not an
affiliate of the Company or, if it is such an affiliate, such Holder will comply
with the registration and prospectus delivery requirements of the Securities Act
to the extent applicable.

                  Notwithstanding any other provisions hereof, the Company and
the Subsidiary Guarantors will ensure that (i) any Exchange Offer Registration
Statement and any amendment thereto and any prospectus forming part thereof and
any supplement thereto complies in all material respects with the Securities Act
and the rules and regulations of the Commission thereunder, (ii) any Exchange
Offer Registration Statement and any amendment thereto does not, when it becomes
effective, contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading and (iii) any prospectus forming part of any Exchange
Offer Registration Statement, and any supplement to such prospectus, does not,
as of the consummation of the Registered Exchange Offer, include an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

                  2. Shelf Registration. If (i) because of any change in law or
applicable interpretations thereof by the Commission's staff the Company is not
permitted to effect the Registered Exchange Offer as contemplated by Section 1
hereof, or (ii) any Securities validly tendered pursuant to the Registered
Exchange Offer are not exchanged for Exchange Securities within 165 days after
the Issue Date, or (iii) any Initial Purchaser so requests with respect to
Securities or Private Exchange Securities not eligible to be exchanged for
Exchange Securities in the Registered Exchange Offer and held by it following
the consummation of the Registered


<PAGE>   4


                                                                               4

Exchange Offer, or (iv) any applicable law or interpretations do not permit any
Holder to participate in the Registered Exchange Offer, or (v) any Holder that
participates in the Registered Exchange Offer does not receive freely
transferable Exchange Securities in exchange for tendered Securities, or (vi)
the Company so elects, then the following provisions shall apply:

                 (a) The Company and the Subsidiary Guarantors shall use their
         reasonable best efforts to file as promptly as practicable (but in no
         event more than 30 days after so required or requested pursuant to this
         Section 2) with the Commission, and thereafter shall use their
         reasonable best efforts to cause to be declared effective, a shelf
         registration statement on an appropriate form under the Securities Act
         relating to the offer and sale of the Transfer Restricted Securities
         (as defined below) by the Holders thereof from time to time in
         accordance with the methods of distribution set forth in such
         registration statement (hereafter, a "Shelf Registration Statement"
         and, together with any Exchange Offer Registration Statement, a
         "Registration Statement").

                 (b) The Company and the Subsidiary Guarantors shall use their
         reasonable best efforts to keep the Shelf Registration Statement
         continuously effective in order to permit the prospectus forming part
         thereof to be used by Holders of Transfer Restricted Securities for a
         period ending on the earlier of (i) two years from the Issue Date or
         such shorter period that will terminate when all the Transfer
         Restricted Securities covered by the Shelf Registration Statement have
         been sold pursuant thereto and (ii) the date on which the Securities
         become eligible for resale without volume restrictions pursuant to Rule
         144 under the Securities Act (in any such case, such period being
         called the "Shelf Registration Period"). The Company and the Subsidiary
         Guarantors shall be deemed not to have used their reasonable best
         efforts to keep the Shelf Registration Statement effective during the
         requisite period if any of them voluntarily take any action that would
         result in Holders of Transfer Restricted Securities covered thereby not
         being able to offer and sell such Transfer Restricted Securities during
         that period, unless such action is required by applicable law.

                 (c) Notwithstanding any other provisions hereof, the Company
         and the Subsidiary Guarantors will ensure that (i) any Shelf
         Registration Statement and any amendment thereto and any prospectus
         forming part thereof and any supplement thereto complies in all
         material respects with the Securities Act and the rules and regulations
         of the Commission thereunder, (ii) any Shelf Registration Statement and
         any amendment thereto (in either case, other than with respect to
         information included therein in reliance upon or in conformity with
         written information furnished to the Company by or on behalf of any
         Holder specifically for use therein (the "Holders' Information")) does
         not contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading and (iii) any prospectus forming part
         of any Shelf Registration Statement, and any supplement to such
         prospectus (in either case, other than with respect to Holders'
         Information), does not include an untrue statement of a material fact
         or omit to state a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading.

                  3. Liquidated Damages. (a) The parties hereto agree that the
Holders of Transfer Restricted Securities will suffer damages if the Company and
the Subsidiary Guarantors fails to fulfill their obligations under Section 1 or
Section 2, as applicable, and that it would not be feasible to ascertain the
extent of such damages. Accordingly, if (i) the applicable Registration
Statement is not filed with the Commission on or prior to 75 days after the
Issue Date, (ii) the Exchange Offer Registration Statement or the Shelf
Registration Statement, as the case may be, is not declared effective within 135
days after the Issue Date (or in the case of a Shelf Registration Statement
required to be filed in response to a change in law or the applicable
interpretations of Commission's staff, if later, within 30 days after
publication of the change in law or interpretation), (iii) the Registered
Exchange Offer is not consummated on or prior to 165 days after the Issue Date,
or (iv) the Shelf Registration Statement is filed and declared effective within


<PAGE>   5


                                                                               5

135 days after the Issue Date (or in the case of a Shelf Registration Statement
required to be filed in response to a change in law or the applicable
interpretations of Commission's staff, if later, within 30 days after
publication of the change in law or interpretation) but shall thereafter cease
to be effective (at any time that the Company is obligated to maintain the
effectiveness thereof) without being succeeded within 30 days by an additional
Registration Statement filed and declared effective (each such event referred to
in clauses (i) through (iv), a "Registration Default"), the Company and the
Subsidiary Guarantors will be jointly and severally obligated to pay liquidated
damages to each Holder of Transfer Restricted Securities, during the period of
one or more such Registration Defaults, in an amount equal to $ 0.192 per week
per $1,000 principal amount of Transfer Restricted Securities held by such
Holder until (i) the applicable Registration Statement is filed, (ii) the
Exchange Offer Registration Statement is declared effective and the Registered
Exchange Offer is consummated, (iii) the Shelf Registration Statement is
declared effective or (iv) the Shelf Registration Statement again becomes
effective, as the case may be. Following the cure of all Registration Defaults,
the accrual of liquidated damages will cease. As used herein, the term "Transfer
Restricted Securities" means (i) each Security until the date on which such
Security has been exchanged for a freely transferable Exchange Security in the
Registered Exchange Offer, (ii) each Security or Private Exchange Security until
the date on which it has been effectively registered under the Securities Act
and disposed of in accordance with the Shelf Registration Statement or (iii)
each Security or Private Exchange Security until the date on which it is
distributed to the public pursuant to Rule 144 under the Securities Act or is
saleable pursuant to Rule 144(k) under the Securities Act. Notwithstanding
anything to the contrary in this Section 3(a), the Company shall not be required
to pay liquidated damages to a Holder of Transfer Restricted Securities if such
Holder failed to comply with its obligations to make the representations set
forth in the second to last paragraph of Section 1 or failed to provide the
information required to be provided by it, if any, pursuant to Section 4(n).

                 (b) The Company shall notify the Trustee and the Paying Agent
under the Indenture immediately upon the happening of each and every
Registration Default. The Company and the Subsidiary Guarantors shall pay the
liquidated damages due on the Transfer Restricted Securities by depositing with
the Paying Agent (which may not be the Company for these purposes), in trust,
for the benefit of the Holders thereof, prior to 10:00 a.m., New York City time,
on the next interest payment date specified by the Indenture and the Securities,
sums sufficient to pay the liquidated damages then due. The liquidated damages
due shall be payable on each interest payment date specified by the Indenture
and the Securities to the record holder entitled to receive the interest payment
to be made on such date. Each obligation to pay liquidated damages shall be
deemed to accrue from and including the date of the applicable Registration
Default.

                 (c) The parties hereto agree that the liquidated damages
provided for in this Section 3 constitute a reasonable estimate of and are
intended to constitute the sole damages that will be suffered by Holders of
Transfer Restricted Securities by reason of the failure of (i) the Shelf
Registration Statement or the Exchange Offer Registration Statement to be filed,
(ii) the Shelf Registration Statement to remain effective or (iii) the Exchange
Offer Registration Statement to be declared effective and the Registered
Exchange Offer to be consummated, in each case to the extent required by this
Agreement.

                  4. Registration Procedures. In connection with any
Registration Statement, the following provisions shall apply:

                 (a) The Company shall (i) furnish to the Initial Purchaser,
         prior to the filing thereof with the Commission, a copy of the
         Registration Statement and each amendment thereof and each supplement,
         if any, to the prospectus included therein and shall use its reasonable
         best efforts to reflect in each such document, when so filed with the
         Commission, such comments as the Initial Purchaser may reasonably
         propose; (ii) include the information set forth in Annex A hereto on
         the cover, in Annex B hereto in the "Exchange Offer Procedures" section
         and the "Purpose of the Exchange Offer" section and in Annex C hereto
         in the "Plan of Distribution" section of the prospectus forming a


<PAGE>   6


                                                                               6

         part of the Exchange Offer Registration Statement, and include the
         information set forth in Annex D hereto in the Letter of Transmittal
         delivered pursuant to the Registered Exchange Offer; and (iii) if
         requested by any Initial Purchaser, include the information required by
         Items 507 or 508 of Regulation S-K, as applicable, in the prospectus
         forming a part of the Exchange Offer Registration Statement.

                 (b) The Company shall advise the Initial Purchaser, each
         Exchanging Dealer and the Holders (if applicable) and, if requested by
         any such person, confirm such advice in writing (which advice pursuant
         to clauses (ii)-(v) hereof shall be accompanied by an instruction to
         suspend the use of the prospectus until the requisite changes have been
         made):

                            (i) when any Registration Statement and any
                  amendment thereto has been filed with the Commission and when
                  such Registration Statement or any post-effective amendment
                  thereto has become effective;

                            (ii) of any request by the Commission for amendments
                  or supplements to any Registration Statement or the prospectus
                  included therein or for additional information;

                            (iii) of the issuance by the Commission of any stop
                  order suspending the effectiveness of any Registration
                  Statement or the initiation of any proceedings for that
                  purpose;

                            (iv) of the receipt by the Company of any
                  notification with respect to the suspension of the
                  qualification of the Securities, the Exchange Securities or
                  the Private Exchange Securities for sale in any jurisdiction
                  or the initiation or threatening of any proceeding for such
                  purpose; and

                            (v) of the happening of any event that requires the
                  making of any changes in any Registration Statement or the
                  prospectus included therein in order that the statements
                  therein are not misleading and do not omit to state a material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading.

                 (c) The Company and the Subsidiary Guarantors will make every
         reasonable effort to obtain the withdrawal at the earliest possible
         time of any order suspending the effectiveness of any Registration
         Statement.

                 (d) The Company will furnish to each Holder of Transfer
         Restricted Securities included within the coverage of any Shelf
         Registration Statement, without charge, at least one conformed copy of
         such Shelf Registration Statement and any post-effective amendment
         thereto, including financial statements and schedules and, if any such
         Holder so requests in writing, all exhibits thereto (including those,
         if any, incorporated by reference).

                 (e) The Company will, during the Shelf Registration Period,
         promptly deliver to each Holder of Transfer Restricted Securities
         included within the coverage of any Shelf Registration Statement,
         without charge, as many copies of the prospectus (including each
         preliminary prospectus) included in such Shelf Registration Statement
         and any amendment or supplement thereto as such Holder may reasonably
         request; and the Company consents to the use of such prospectus or any
         amendment or supplement thereto by each of the selling Holders of
         Transfer Restricted Securities in connection with the offer and sale of
         the Transfer Restricted Securities covered by such prospectus or any
         amendment or supplement thereto.

                                                                               7

                 (f) The Company will furnish to the Initial Purchaser and each
         Exchanging Dealer, and to any other Holder who so requests, without
         charge, at least one conformed copy of the Exchange Offer Registration
         Statement and any post-effective amendment thereto, including financial
         statements and schedules and, if the Initial Purchaser or Exchanging
         Dealer or any such Holder so requests in writing, all exhibits thereto
         (including those, if any, incorporated by reference).

                 (g) The Company will, during the Exchange Offer Registration
         Period or the Shelf Registration Period, as applicable, promptly
         deliver to the Initial Purchaser, each Exchanging Dealer and such other
         persons that are required to deliver a prospectus following the
         Registered Exchange Offer, without charge, as many copies of the final
         prospectus included in the Exchange Offer Registration Statement or the
         Shelf Registration Statement and any amendment or supplement thereto as
         the Initial Purchaser, such Exchanging Dealer or other persons may
         reasonably request; and the Company and the Subsidiary Guarantors
         consent to the use of such prospectus or any amendment or supplement
         thereto by the Initial Purchaser, such Exchanging Dealer or other
         persons, as applicable, as aforesaid.

                 (h) Prior to the effective date of any Registration Statement,
         the Company and the Subsidiary Guarantors will use their reasonable
         best efforts to register or qualify, or cooperate with the Holders of
         Securities, Exchange Securities or Private Exchange Securities included
         therein and their respective counsel in connection with the
         registration or qualification of, such Securities, Exchange Securities
         or Private Exchange Securities for offer and sale under the securities
         or blue sky laws of such jurisdictions as any such Holder reasonably
         requests in writing and do any and all other acts or things necessary
         or advisable to enable the offer and sale in such jurisdictions of the
         Securities, Exchange Securities or Private Exchange Securities covered
         by such Registration Statement; provided that the Company and the
         Subsidiary Guarantors will not be required to qualify generally to do
         business in any jurisdiction where they are not then so qualified or to
         take any action which would subject them to general service of process
         or to taxation in any such jurisdiction where they are not then so
         subject.

                 (i) The Company and the Subsidiary Guarantors will cooperate
         with the Holders of Securities, Exchange Securities or Private Exchange
         Securities to facilitate the timely preparation and delivery of
         certificates representing Securities, Exchange Securities or Private
         Exchange Securities to be sold pursuant to any Registration Statement
         free of any restrictive legends and in such denominations and
         registered in such names as the Holders thereof may request in writing
         prior to sales of Securities, Exchange Securities or Private Exchange
         Securities pursuant to such Registration Statement.

                 (j) If any event contemplated by Section 4(b)(ii) through (v)
         occurs during the period for which the Company and the Subsidiary
         Guarantors are required to maintain an effective Registration
         Statement, the Company and the Subsidiary Guarantors will promptly
         prepare and file with the Commission a post-effective amendment to the
         Registration Statement or a supplement to the related prospectus or
         file any other required document so that, as thereafter delivered to
         purchasers of the Securities, Exchange Securities or Private Exchange
         Securities from a Holder, the prospectus will not include an untrue
         statement of a material fact or omit to state a material fact necessary
         in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading.

                 (k) Not later than the effective date of the applicable
         Registration Statement, the Company will provide a CUSIP number for the
         Securities, the Exchange Securities and the Private Exchange
         Securities, as the case may be, and provide the applicable trustee with
         printed certificates for the Securities, the Exchange Securities or the
         Private Exchange Securities, as the case may be, in a form eligible for
         deposit with The Depository Trust Company.

                 (l) The Company and the Subsidiary Guarantors will comply with
         all applicable rules and regulations of the Commission and the Company
         will make generally available to its security holders as soon as
         practicable after the effective date of the applicable Registration
         Statement an earning statement satisfying the provisions of Section
         11(a) of the Securities Act; provided that in no event shall such
         earning statement be delivered later than 45 days after the end of a
         12-month period (or 90 days, if such period is a fiscal year) beginning
         with the first month of the Company's first fiscal quarter commencing
         after the effective date of the applicable Registration Statement,
         which statement shall cover such 12-month period.

                 (m) The Company and the Subsidiary Guarantors will cause the
         Indenture or the Exchange Securities Indenture, as the case may be, to
         be qualified under the Trust Indenture Act as required by applicable
         law in a timely manner.

                 (n) The Company may require each Holder of Transfer Restricted
         Securities to be registered pursuant to any Shelf Registration
         Statement to furnish to the Company such information concerning the
         Holder and the distribution of such Transfer Restricted Securities as
         the Company may from time to time reasonably require for inclusion in
         such Shelf Registration Statement, and the Company may exclude from
         such registration the Transfer Restricted Securities of any Holder that
         fails to furnish such information within a reasonable time after
         receiving such request.

                 (o) In the case of a Shelf Registration Statement, each Holder
         of Transfer Restricted Securities to be registered pursuant thereto
         agrees by acquisition of such Transfer Restricted Securities that, upon
         receipt of any notice from the Company pursuant to Section 4(b)(ii)
         through (v), such Holder will discontinue disposition of such Transfer
         Restricted Securities until such Holder's receipt of copies of the
         supplemental or amended prospectus contemplated by Section 4(j) or
         until advised in writing (the "Advice") by the Company that the use of
         the applicable prospectus may be resumed. If the Company shall give any
         notice under Section 4(b)(ii) through (v) during the period that the
         Company is required to maintain an effective Registration Statement
         (the "Effectiveness Period"), such Effectiveness Period shall be
         extended by the number of days during such period from and including
         the date of the giving of such notice to and including the date when
         each seller of Transfer Restricted Securities covered by such
         Registration Statement shall have received (x) the copies of the
         supplemental or amended prospectus contemplated by Section 4(j) (if an
         amended or supplemental prospectus is required) or (y) the Advice (if
         no amended or supplemental prospectus is required).

                 (p) In the case of a Shelf Registration Statement, the Company
         and the Subsidiary Guarantors shall enter into such customary
         agreements (including, if requested, an underwriting agreement in
         customary form) and take all such other action, if any, as Holders of a
         majority in aggregate principal amount of the Securities, Exchange
         Securities and Private Exchange Securities being sold or the managing
         underwriters (if any) shall reasonably request in order to facilitate
         any disposition of Securities, Exchange Securities or Private Exchange
         Securities pursuant to such Shelf Registration Statement.

                 (q) In the case of a Shelf Registration Statement, the Company
         shall (i) make reasonably available for inspection by a representative
         of, and Special Counsel (as defined below) acting for, Holders of a
         majority in aggregate principal amount of the Securities, Exchange
         Securities and Private Exchange Securities being sold and any
         underwriter participating in any disposition of Securities, Exchange
         Securities or Private Exchange Securities pursuant to such Shelf
         Registration Statement, all relevant financial and other records,
         pertinent corporate documents and properties of the Company and its
         subsidiaries and (ii) use its reasonable best efforts to have its
         officers, directors, employees, accountants and counsel supply all
         relevant information reasonably requested by such representative,
         Special Counsel or any such underwriter (an "Inspector") in connection
         with such Shelf Registration Statement.

                                                                               9

                 (r) In the case of a Shelf Registration Statement, the Company
         shall, if requested by Holders of a majority in aggregate principal
         amount of the Securities, Exchange Securities and Private Exchange
         Securities being sold, their Special Counsel or the managing
         underwriters (if any) in connection with such Shelf Registration
         Statement, use its reasonable best efforts to cause (i) its counsel to
         deliver an opinion relating to the Shelf Registration Statement and the
         Securities, Exchange Securities or Private Exchange Securities, as
         applicable, in customary form, (ii) its officers to execute and deliver
         all customary documents and certificates requested by Holders of a
         majority in aggregate principal amount of the Securities, Exchange
         Securities and Private Exchange Securities being sold, their Special
         Counsel or the managing underwriters (if any) and (iii) its independent
         public accountants to provide a comfort letter or letters in customary
         form, subject to receipt of appropriate documentation as contemplated,
         and only if permitted, by Statement of Auditing Standards No. 72.

                  5. Registration Expenses. The Company and the Subsidiary
Guarantors will jointly and severally bear all expenses incurred in connection
with the performance of its obligations under Sections 1, 2, 3 and 4 and the
Company will reimburse the Initial Purchaser and the Holders for the reasonable
fees and disbursements of one firm of attorneys (in addition to any local
counsel) chosen by the Holders of a majority in aggregate principal amount of
the Securities, the Exchange Securities and the Private Exchange Securities to
be sold pursuant to each Registration Statement (the "Special Counsel") acting
for the Initial Purchaser or Holders in connection therewith.

                  6. Indemnification. (a) In the event of a Shelf Registration
Statement or in connection with any prospectus delivery pursuant to an Exchange
Offer Registration Statement by the Initial Purchaser or Exchanging Dealer, as
applicable, the Company and the Subsidiary Guarantors shall jointly and
severally indemnify and hold harmless each Holder (including, without
limitation, the Initial Purchaser or such Exchanging Dealer), its affiliates,
their respective officers, directors, employees, representatives and agents, and
each person, if any, who controls such Holder within the meaning of the
Securities Act or the Exchange Act (collectively referred to for purposes of
this Section 6 and Section 7 as a Holder) from and against any loss, claim,
damage or liability, joint or several, or any action in respect thereof
(including, without limitation, any loss, claim, damage, liability or action
relating to purchases and sales of Securities, Exchange Securities or Private
Exchange Securities), to which that Holder may become subject, whether commenced
or threatened, under the Securities Act, the Exchange Act, any other federal or
state statutory law or regulation, at common law or otherwise, insofar as such
loss, claim, damage, liability or action arises out of, or is based upon, (i)
any untrue statement or alleged untrue statement of a material fact contained in
any such Registration Statement or any prospectus forming part thereof or in any
amendment or supplement thereto or (ii) the omission or alleged omission to
state therein a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, and shall reimburse each Holder promptly
upon demand for any legal or other expenses reasonably incurred by that Holder
in connection with investigating or defending or preparing to defend against or
appearing as a third party witness in connection with any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company and the Subsidiary Guarantors shall not be liable in any such
case to the extent that any such loss, claim, damage, liability or action arises
out of, or is based upon, an untrue statement or alleged untrue statement in or
omission or alleged omission from any of such documents in reliance upon and in
conformity with any Holders' Information; and provided, further, that with
respect to any such untrue statement in or omission from any related preliminary
prospectus, the indemnity agreement contained in this Section 6(a) shall not
inure to the benefit of any Holder from whom the person asserting any such loss,
claim, damage, liability or action received Securities, Exchange Securities or
Private Exchange Securities to the extent that such loss, claim, damage,
liability or action of or with respect to such Holder results from the fact that
both (A) a copy of the final prospectus was not sent or given to such person at
or prior to the written confirmation of the sale of such Securities, Exchange
Securities or Private Exchange Securities to such person and (B) the untrue
statement in or omission from the related preliminary prospectus


<PAGE>   10


                                                                              10

was corrected in the final prospectus unless, in either case, such failure to
deliver the final prospectus was a result of non-compliance by the Company with
Section 4(d), 4(e), 4(f) or 4(g).

                 (b) In the event of a Shelf Registration Statement, each Holder
shall indemnify and hold harmless the Company, its affiliates, their respective
officers, directors, employees, representatives and agents, and each person, if
any, who controls the Company within the meaning of the Securities Act or the
Exchange Act (collectively referred to for purposes of this Section 6(b) and
Section 7 as the Company), from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof, to which the
Company may become subject, whether commenced or threatened, under the
Securities Act, the Exchange Act, any other federal or state statutory law or
regulation, at common law or otherwise, insofar as such loss, claim, damage,
liability or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in any such Registration
Statement or any prospectus forming part thereof or in any amendment or
supplement thereto or (ii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with any Holders' Information furnished to
the Company by such Holder, and shall reimburse the Company for any legal or
other expenses reasonably incurred by the Company in connection with
investigating or defending or preparing to defend against or appearing as a
third party witness in connection with any such loss, claim, damage, liability
or action as such expenses are incurred; provided, however, that no such Holder
shall be liable for any indemnity claims hereunder in excess of the amount of
net proceeds received by such Holder from the sale of Securities, Exchange
Securities or Private Exchange Securities pursuant to such Shelf Registration
Statement.

                 (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying
party in writing of the claim or the commencement of that action; provided,
however, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have under this Section 6 except to the extent
that it has been materially prejudiced (through the forfeiture of substantive
rights or defenses) by such failure; and provided, further, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have to an indemnified party otherwise than under this Section 6. If any
such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than the reasonable costs of investigation; provided, however,
that an indemnified party shall have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel for the
indemnified party will be at the expense of such indemnified party unless (1)
the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (2) the indemnified party has reasonably
concluded (based upon advice of counsel to the indemnified party) that there may
be legal defenses available to it or other indemnified parties that are
different from or in addition to those available to the indemnifying party, (3)
a conflict or potential conflict exists (based upon advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (4) the indemnifying party
has not in fact employed counsel reasonably satisfactory to the indemnified
party to assume the defense of such action within a reasonable time after
receiving notice of the commencement of the action, in each of which cases the
reasonable fees, disbursements and other charges of counsel will be at the
expense of the indemnifying party or parties. It is understood that the
indemnifying party or parties shall not, in connection with any


<PAGE>   11


                                                                              11

proceeding or related proceedings in the same jurisdiction, be liable for the
reasonable fees, disbursements and other charges of more than one separate firm
of attorneys (in addition to any local counsel) at any one time for all such
indemnified party or parties. Each indemnified party, as a condition of the
indemnity agreements contained in Sections 6(a) and 6(b), shall use all
reasonable efforts to cooperate with the indemnifying party in the defense of
any such action or claim. No indemnifying party shall be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment for the plaintiff in any such action,
the indemnifying party agrees to indemnify and hold harmless any indemnified
party from and against any loss or liability by reason of such settlement or
judgment. No indemnifying party shall, without the prior written consent of the
indemnified party (which consent shall not be unreasonably withheld), effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

                  7. Contribution. If the indemnification provided for in
Section 6 is unavailable or insufficient to hold harmless an indemnified party
under Section 6(a) or 6(b), then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company from the offering and sale
of the Securities, on the one hand, and a Holder with respect to the sale by
such Holder of Securities, Exchange Securities or Private Exchange Securities,
on the other, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and the Subsidiary Guarantors, on the one hand, and such
Holder, on the other, with respect to the statements or omissions that resulted
in such loss, claim, damage or liability, or action in respect thereof, as well
as any other relevant equitable considerations. The relative benefits received
by the Company and the Subsidiary Guarantors, on the one hand, and a Holder, on
the other, with respect to such offering and such sale shall be deemed to be in
the same proportion as the total net proceeds from the offering of the
Securities (before deducting expenses) received by or on behalf of the Company
as set forth in the table on the cover of the Offering Memorandum, on the one
hand, bear to the total proceeds received by such Holder with respect to its
sale of Securities, Exchange Securities or Private Exchange Securities, on the
other. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to the Company and
the Subsidiary Guarantors or information supplied by the Company and the
Subsidiary Guarantors, on the one hand, or to any Holders' Information supplied
by such Holder, on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The parties hereto agree that it would not be just
and equitable if contributions pursuant to this Section 7 were to be determined
by pro rata allocation or by any other method of allocation that does not take
into account the equitable considerations referred to herein. The amount paid or
payable by an indemnified party as a result of the loss, claim, damage or
liability, or action in respect thereof, referred to above in this Section 7
shall be deemed to include, for purposes of this Section 7, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending or preparing to defend any such action or claim.
Notwithstanding the provisions of this Section 7, an indemnifying party that is
a Holder of Securities, Exchange Securities or Private Exchange Securities shall
not be required to contribute any amount in excess of the amount by which the
total price at which the Securities, Exchange Securities or Private Exchange
Securities sold by such indemnifying party to any purchaser exceeds the amount
of any damages which such indemnifying party has otherwise paid or become liable
to pay by reason of any untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                                                                              12

                  8. Rules 144 and 144A. The Company shall use its reasonable
best efforts to file the reports required to be filed by it under the Securities
Act and the Exchange Act in a timely manner and, if at any time the Company is
not required to file such reports, it will, upon the written request of any
Holder of Transfer Restricted Securities, make publicly available other
information so long as necessary to permit sales of such Holder's securities
pursuant to Rules 144 and 144A. The Company and the Subsidiary Guarantors
covenant that they will take such further action as any Holder of Transfer
Restricted Securities may reasonably request, all to the extent required from
time to time to enable such Holder to sell Transfer Restricted Securities
without registration under the Securities Act within the limitation of the
exemptions provided by Rules 144 and 144A (including, without limitation, the
requirements of Rule 144A(d)(4)). Upon the written request of any Holder of
Transfer Restricted Securities, the Company and the Subsidiary Guarantors shall
deliver to such Holder a written statement as to whether they have complied with
such requirements. Notwithstanding the foregoing, nothing in this Section 8
shall be deemed to require the Company to register any of its securities
pursuant to the Exchange Act.

                  9. Underwritten Registrations. If any of the Transfer
Restricted Securities covered by any Shelf Registration Statement are to be sold
in an underwritten offering, the investment banker or investment bankers and
manager or managers that will administer the offering will be selected by the
Holders of a majority in aggregate principal amount of such Transfer Restricted
Securities included in such offering, subject to the consent of the Company
(which shall not be unreasonably withheld or delayed), and such Holders shall be
responsible for all underwriting commissions and discounts in connection
therewith.

                  No person may participate in any underwritten registration
hereunder unless such person (i) agrees to sell such person's Transfer
Restricted Securities on the basis reasonably provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

                 10. Miscellaneous. (a) Amendments and Waivers. The provisions
of this Agreement may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, unless the
Company has obtained the written consent of Holders of a majority in aggregate
principal amount of the Securities, the Exchange Securities and the Private
Exchange Securities, taken as a single class. Notwithstanding the foregoing, a
waiver or consent to depart from the provisions hereof with respect to a matter
that relates exclusively to the rights of Holders whose Securities, Exchange
Securities or Private Exchange Securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of a majority in aggregate
principal amount of the Securities, the Exchange Securities and the Private
Exchange Securities being sold by such Holders pursuant to such Registration
Statement.

                    (b) Notices. All notices and other communications provided
for or permitted hereunder shall be made in writing by hand-delivery,
first-class mail, telecopier or air courier guaranteeing next-day delivery:

                     (1) if to a Holder, at the most current address given by
         such Holder to the Company in accordance with the provisions of this
         Section 10(b), which address initially is, with respect to each Holder,
         the address of such Holder maintained by the Registrar under the
         Indenture, with a copy in like manner to Chase Securities Inc.;

                     (2) if to the Initial Purchaser, initially at its address
         set forth in the Purchase Agreement; and

                     (3) if to the Company, initially at the address of the
         Company set forth in the Purchase Agreement.

                  All such notices and communications shall be deemed to have
been duly given: when delivered by hand, if personally delivered; one business
day after being delivered to a next-day air courier; five business days after
being deposited in the mail; and when receipt is acknowledged by the recipient's
telecopier machine, if sent by telecopier.

                 (c) Successors And Assigns. This Agreement shall be binding
upon the Company and its successors and assigns.

                 (d) Counterparts. This Agreement may be executed in any number
of counterparts (which may be delivered in original form or by telecopier) and
by the parties hereto in separate counterparts, each of which when so executed
shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

                 (e) Definition of Terms. For purposes of this Agreement, (a)
the term "business day" means any day on which the New York Stock Exchange, Inc.
is open for trading, (b) the term "subsidiary" has the meaning set forth in Rule
405 under the Securities Act and (c) except where otherwise expressly provided,
the term "affiliate" has the meaning set forth in Rule 405 under the Securities
Act.

                 (f) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                 (g)  GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK.

                 (h) Remedies. In the event of a breach by the Company, any
Subsidiary Guarantor or by any Holder of any of their obligations under this
Agreement, each Holder, the Company or any Subsidiary Guarantor, as the case may
be, in addition to being entitled to exercise all rights granted by law,
including recovery of damages (other than the recovery of damages for a breach
by the Company or any Subsidiary Guarantor of its obligations under Sections 1
or 2 hereof for which liquidated damages have been paid pursuant to Section 3
hereof), will be entitled to specific performance of its rights under this
Agreement. The Company, the Subsidiary Guarantors and each Holder agree that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by each such person of any of the provisions of this
Agreement and hereby further agree that, in the event of any action for specific
performance in respect of such breach, each such person shall waive the defense
that a remedy at law would be adequate.

                 (i) No Inconsistent Agreements. The Company and each Subsidiary
Guarantor represents, warrants and agrees that (i) it has not entered into,
shall not, on or after the date of this Agreement, enter into any agreement that
is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof, (ii) it has not previously
entered into any agreement which remains in effect granting any registration
rights with respect to any of its debt securities to any person and (iii) (with
respect to the Company) without limiting the generality of the foregoing,
without the written consent of the Holders of a majority in aggregate principal
amount of the then outstanding Transfer Restricted Securities, it shall not
grant to any person the right to request the Company to register any debt
securities of the Company under the Securities Act unless the rights so granted
are not in conflict or inconsistent with the provisions of this Agreement.

                 (j) No Piggyback on Registrations. Neither the Company nor any
of its security holders (other than the Holders of Transfer Restricted
Securities in such capacity) shall have the right to include any securities of
the Company in any Shelf Registration or Registered Exchange Offer other than

                  Each broker-dealer that receives Exchange Securities for its
own account pursuant to the Registered Exchange Offer must acknowledge that it
will deliver a prospectus in connection with any resale of such Exchange
Securities. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. This Prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of Exchange Securities received in
exchange for Securities where such Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that, for a period of 180 days after the
Expiration Date (as defined herein), it will make this Prospectus available to
any broker-dealer for use in connection with any such resale. See "Plan of
Distribution".

                  Each broker-dealer that receives Exchange Securities for its

such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection

                              PLAN OF DISTRIBUTION


                    Each broker-dealer that receives Exchange Securities for its
own account pursuant to the Registered Exchange Offer must acknowledge that it
will deliver a prospectus in connection with any resale of such Exchange
Securities. This Prospectus, as it may be amended or supplemented from time to
time, may be used by a broker-dealer in connection with resales of Exchange
Securities received in exchange for Securities where such Securities were
acquired as a result of market-making activities or other trading activities.
The Company has agreed that, for a period of 180 days after the Expiration Date,
it will make this prospectus, as amended or supplemented, available to any
broker-dealer for use in connection with any such resale. In addition, until 
[             ] 199[ ], all dealers effecting transactions in the Exchange 
Securities may be required to deliver a prospectus.

                  The Company will not receive any proceeds from any sale of
Exchange Securities by broker-dealers. Exchange Securities received by
broker-dealers for their own account pursuant to the Registered Exchange Offer
may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the Exchange Securities or a combination of such methods of resale,
at market prices prevailing at the time of resale, at prices related to such
prevailing market prices or at negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such Exchange Securities. Any
broker-dealer that resells Exchange Securities that were received by it for its
own account pursuant to the Registered Exchange Offer and any broker or dealer
that participates in a distribution of such Exchange Securities may be deemed to
be an "underwriter" within the meaning of the Securities Act and any profit on
any such resale of Exchange Securities and any commission or concessions
received by any such persons may be deemed to be underwriting compensation under
the Securities Act. The Letter of Transmittal states that, by acknowledging that
it will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.

                  For a period of 180 days after the Expiration Date the Company
will promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Registered Exchange Offer (including the expenses of one counsel
for the Holders of the Securities) other than commissions or concessions of any
broker-dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
