Trustee authenticates the Note, the Note shall be valid nevertheless.

                  No Note shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any Note

have been authenticated and delivered hereunder and shall never be entitled to

additional series of Notes in an aggregate principal amount not to exceed

Exchange. Exchange Notes or Private Exchange Notes may have such distinctive
series designations and such changes in the form thereof as are specified in the
Company Request referred to in the preceding sentence. The Notes shall be
issuable only in registered form without coupons and only in denominations of
$1,000 and integral multiples thereof.

                  The Trustee may appoint an authenticating agent reasonably

Agent. Neither the Company nor any Affiliate thereof may act as Paying Agent.

                  The Company shall enter into an appropriate agency agreement
with any Agent not a party to this Indenture, which shall incorporate the
provisions 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

paid to it by the Company or any other obligor on the Notes), and the Company
and the Paying Agent shall notify the Trustee of any default by the Company (or
any other obligor on the Notes) in making any such payment. Money held in trust
by the Paying Agent need not be segregated except as required by law and in no
event shall the Paying Agent be liable for any interest on any money received by
it hereunder. The Company at any time may require the Paying Agent to pay all
money held by it to the Trustee and account for any funds disbursed and the
Trustee may at any time during the continuance of any Event of Default specified
in Section 6.01 (1) or (2), upon written request to the Paying Agent, require
such Paying Agent to pay forthwith all money so held by it to the Trustee and to
account for any funds disbursed. Upon making such payment, the Paying Agent
shall have no further liability for the money delivered to the Trustee.

                  Any money deposited with any Paying Agent, or then held by the
Company or a Subsidiary in trust for the payment of principal or interest on any
Note and remaining unclaimed for two years after such principal and interest has
become due and payable shall be paid to the Company at its request, or, if then
held by the Company or a Subsidiary, shall be discharged from such trust; and
the Noteholders shall thereafter, as unsecured



   37


                                      -30-



general creditors, look only to the Company for payment thereof, and all

the Company or such Subsidiary as trustee thereof, shall thereupon cease.

                  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 the Noteholders. If the Trustee is not the Registrar, the Company
shall furnish to the Trustee 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 the Noteholders.

Section 2.06.  Transfer and Exchange.
               ----------------------

                  Subject to Sections 2.15 and 2.16, when Notes are presented to
the Registrar with a request from the Holder of such Notes to register a
transfer or to exchange them for an equal principal amount of Notes of other
authorized denominations, the Registrar shall register the transfer as
requested. Every Note presented or surrendered for registration of transfer or
exchange shall be duly endorsed or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Registrar, duly executed by
the Holder thereof or his attorneys duly authorized in writing. To permit
registrations of transfers and exchanges, the Company shall issue and execute
and the Trustee shall authenticate new Notes (and the Guarantors shall execute
the guarantee thereon) evidencing such transfer or exchange at the Registrar's
request. No service charge shall be made to the Noteholder for any registration
of transfer or exchange. The Company may require from the Noteholder payment of
a sum sufficient to cover any transfer taxes or other governmental charge that
may be imposed in relation to a transfer or exchange, but this provision shall
not apply to any exchange pursuant to Section 2.02, 2.10, 3.06, 4.10, 4.19 or
8.05 (in which events the Company shall be responsible for the payment of such
taxes). The Registrar shall not be required to exchange or register a transfer
of any Note for a period of 15 days immediately preceding the mailing of notice
of redemption of Notes to be redeemed or of any Note selected, called or being
called for redemption except the unredeemed portion of any Note being redeemed
in part.

                  Any Holder of the Global Note shall, by acceptance of such
Global Note, agree that transfers of the beneficial



   38


                                      -31-



interests in such Global Note may be effected only through a book entry system
maintained by the Holder of such Global Note (or its agent), and that ownership
of a beneficial interest in the Global Note shall be required to be reflected in
a book entry.

                  Each Holder of a Note agrees to indemnify the Company and the
Trustee against any liability that may result from the transfer, exchange or
assignment of such Holder's Note in violation of any provision of this Indenture
and/or applicable U.S. Federal or state securities law.

                  Except as expressly provided herein, neither the Trustee nor
the Registrar shall have any duty to monitor the Company's compliance with or
have any responsibility with respect to the Company's compliance with any
Federal or state securities laws.

Section 2.07.  Replacement Notes.
               ------------------

                  If a mutilated Note is surrendered to the Registrar or the
Trustee, or if the Holder of a Note claims that the Note has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall
authenticate a replacement Note (and the Guarantors shall execute the guarantee
thereon) if the Holder of such Note furnishes to the Company and the Trustee
evidence reasonably acceptable to them of the ownership and the destruction,
loss or theft of such Note and if the requirements of Section 8-405 of the New
York Uniform Commercial Code as in effect on the date of this Indenture are met.
If required by the Trustee or the Company, an indemnity bond shall be posted,
sufficient in the judgment of both to protect the Company, the Trustee or any
Paying Agent from any loss that any of them may suffer if such Note is replaced.
The Company may charge such Holder for the Company's reasonable out-of-pocket
expenses in replacing such Note and the Trustee may charge the Company for the
Trustee's expenses (including, without limitation, attorneys' fees and
disbursements) in replacing such Note. Every replacement Note shall constitute a
contractual obligation of the Company. In the event any such mutilated, lost,
destroyed or wrongfully taken Note has become due and payable, the Company in
its discretion may pay such Note instead of issuing a new Note in replacement
thereof.

Section 2.08.  Outstanding Notes.
               ------------------

                  The Notes outstanding at any time are all Notes that have been
authenticated by the Trustee except for (a) those cancelled by it, (b) those
delivered to it for cancellation,



   39


                                      -32-



(c) to the extent set forth in Sections 9.01 and 9.02, on or after the date on
which the conditions set forth in Section 9.01 or 9.02 have been satisfied,
those Notes theretofore authenticated and delivered by the Trustee hereunder and
(d) those described in this Section 2.08 as not outstanding. Subject to Section
2.09, a Note does not cease to be outstanding because the Company or one of its
Affiliates holds the Note.

                  If a Note is replaced pursuant to Section 2.07 (other than a
mutilated Note surrendered for replacement), it ceases to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Note is held by
a bona fide purchaser in whose hands such Note is a legal, valid and binding
obligation of the Company. A mutilated Note ceases to be outstanding upon
surrender of such Note and replacement thereof pursuant to Section 2.07.

                  If the Paying Agent holds, in its capacity as such, on any
Maturity Date or on any optional redemption date, money sufficient to pay all
accrued interest and principal with respect to the Notes payable on that date
and is not prohibited from paying such money to the Holders thereof pursuant to
the terms of this Indenture, then on and after that date such Notes cease to be
outstanding and interest on them ceases to accrue.

Section 2.09.  Treasury Notes.
               ---------------

                  In determining whether the Holders of the required principal
amount of Notes have concurred in any declaration of acceleration or notice of
default or direction, waiver or consent or any amendment, modification or other
change to this Indenture, Notes owned by the Company or any other Affiliate of
the Company shall be disregarded as though they were not outstanding, except
that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent or any amendment, modification
or other change to this Indenture, only Notes as to which a Responsible Officer
of the Trustee has received an Officers' Certificate stating that such Notes are
so owned shall be so disregarded. Notes so owned which have been pledged in good
faith shall not be disregarded if the pledgee established to the satisfaction of
the Trustee the pledgee's right so to act with respect to the Notes and that the
pledgee is not the Company, a Guarantor, any other obligor on the Notes or any
of their respective Affiliates.



   40


                                      -33-




Section 2.10.  Temporary Notes.
               ----------------

                  Until definitive Notes are prepared and ready for delivery,
the Company may prepare and the Trustee shall authenticate temporary Notes.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company considers appropriate for temporary Notes.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate definitive Notes in exchange for temporary Notes. Until such
exchange, temporary Notes shall be entitled to the same rights, benefits and
privileges as definitive Notes.

Section 2.11.  Cancellation.
               -------------

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and shall (subject to the
record-retention requirements of the Exchange Act) destroy cancelled Notes and
deliver a certificate of destruction thereof to the Company. The Company may not
reissue or resell, or issue new Notes to replace, Notes that the Company has
redeemed or paid, or that have been delivered to the Trustee for cancellation.

Section 2.12.  Defaulted Interest.
               -------------------

                  If the Company defaults on a payment of interest on the Notes,
it shall pay the defaulted interest, plus (to the extent permitted by law) any
interest payable on the defaulted interest, in accordance with the terms hereof,
to the Persons who are Noteholders on a subsequent special record date, which
date shall be at least five Business Days prior to the payment date. The Company
shall fix such special record date and payment date in a manner satisfactory to
the Trustee. At least 15 days before such special record date, the Company shall
mail to each Noteholder a notice that states the special record date, the
payment date and the amount of defaulted interest, and interest payable on
defaulted interest, if any, to be paid. The Company may make payment of any
defaulted interest in any other lawful manner not inconsistent with the
requirements (if applicable) of any securities exchange on which the Notes may
be listed and, upon such notice as may be required by such exchange, if, after
written notice given by the Company to the Trustee of the



   41


                                      -34-



proposed payment pursuant to this sentence, such manner of payment shall be
deemed practicable by the Trustee.

Section 2.13.  CUSIP Number.
               -------------

                  The Company in issuing the Notes may use a "CUSIP" number, and
if so, such CUSIP number shall be included in notices of redemption or exchange
as a convenience to Holders; PROVIDED, that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Notes, and that reliance may be placed only on
the other identification numbers printed on the Notes. The Company shall
promptly notify the Trustee of any such CUSIP number used by the Company in
connection with the issuance of the Notes and of any change in the CUSIP number.

Section 2.14.  Deposit of Moneys.
               ------------------

                  Prior to 10:00 a.m., New York City time, on each Interest
Payment Date and Maturity Date, the Company shall have deposited with the Paying
Agent in immediately available funds money sufficient to make cash payments, if
any, due on such Interest Payment Date or Maturity Date, as the case may be, in
a timely manner which permits the Trustee to remit payment to the Holders on
such Interest Payment Date or Maturity Date, as the case may be. The principal
and interest on Global Notes shall be payable to the Depository or its nominee,
as the case may be, as the sole registered owner and the sole holder of the
Global Notes represented thereby. The principal and interest on Physical Notes
shall be payable at the office of the Paying Agent.

Section 2.15.  Book-Entry Provisions for Global Notes.
               ---------------------------------------

                  (a) Rule 144A Notes initially shall be represented by one or
more notes in registered, global form without interest coupons (collectively,
the "RESTRICTED GLOBAL NOTE"). Regulation S Notes initially shall be represented
by one or more notes in registered, global form without interest coupons
(collectively, the "REGULATION S GLOBAL NOTE," and, together with the Restricted
Global Note and any other global notes representing Notes, the "GLOBAL NOTES").
The Global Notes initially shall (i) be registered in the name of the Depository
or the nominee of such Depository, in each case for credit to an account of an
Agent Member (or, in the case of the Regulation S Global Notes, of Euroclear
System ("EUROCLEAR") and Cedel Bank, S.A. ("CEDEL")), (ii) be delivered to the
Trustee as custodian for such Depository and (iii) bear legends as set forth in
EXHIBIT D.




   42


                                      -35-



                  Members of, or direct or indirect participants in, the
Depository ("AGENT MEMBERS") shall have no rights under this Indenture with
respect to any Global Note held on their behalf by the Depository, or the
Trustee as its custodian, or under the Global Notes, and the Depository may be
treated by the Company, the Trustee and any agent of the Company or the Trustee
as the absolute owner of the Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any
Note.

                  (b) Transfers of Global Notes shall be limited to transfer in
whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Notes may be transferred
or exchanged for Physical Notes in accordance with the rules and procedures of
the Depository and the provisions of Section 2.16. In addition, a Global Note
shall be exchangeable for Physical Notes if (i) the Depository (x) notifies the
Company that it is unwilling or unable to continue as depository for such Global
Note and the Company thereupon fails to appoint a successor depository or (y)
has ceased to be a clearing agency registered under the Exchange Act, (ii) the
Company, at its option, notifies the Trustee in writing that it elects to cause
the issuance of such Physical Notes or (iii) there shall have occurred and be
continuing an Event of Default with respect to the Notes. In all cases, Physical
Notes delivered in exchange for any Global Note or beneficial interests therein
shall be registered in the names, and issued in any approved denominations,
requested by or on behalf of the Depository (in accordance with its customary
procedures).

                  (c) In connection with any transfer or exchange of a portion
of the beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Company
shall execute, and the Trustee shall upon receipt of a written order from the
Company authenticate and make available for delivery, one or more Physical Notes
of like tenor and amount.




   43


                                      -36-



                  (d) In connection with the transfer of Global Notes as an
entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall
be deemed to be surrendered to the Trustee for cancellation, and the Company
shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depository in writing in exchange for its
beneficial interest in the Global Notes, an equal aggregate principal amount of
Physical Notes of authorized denominations.

                  (e) Any Physical Note constituting a Restricted Note delivered
in exchange for an interest in a Global Note pursuant to paragraph (b), (c) or
(d) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of
Section 2.16, bear the Private Placement Legend or, in the case of the
Regulation S Global Note, the legend set forth in EXHIBIT C, in each case,
unless the Company determines otherwise in compliance with applicable law.

                  (f) On or prior to the 40th day after the later of the
commencement of the offering of the Notes represented by the Regulation S Global
Note and the issue date of such Notes (such period through and including such
40th day, the "RESTRICTED PERIOD"), a beneficial interest in a Regulation S
Global Note may be transferred to a Person who takes delivery in the form of an
interest in the corresponding Restricted Global Note only upon receipt by the
Trustee of a written certification from the transferor to the effect that such
transfer is being made (i)(a) to a Person whom the transferor reasonably
believes is a Qualified Institutional Buyer in a transaction meeting the
requirements of Rule 144A or (b) pursuant to another exemption from the
registration requirements under the Securities Act which is accompanied by an
opinion of counsel regarding the availability of such exemption and (ii) in
accordance with all applicable securities laws of any state of the United States
or any other jurisdiction.

                  (g) Beneficial interests in the Restricted Global Note may be
transferred to a Person who takes delivery in the form of an interest in the
Regulation S Global Note, whether before or after the expiration of the
Restricted Period, only if the transferor first delivers to the Trustee a
written certificate to the effect that such transfer is being made in accordance
with Rule 903 or 904 of Regulation S or Rule 144 (if available) and that, if
such transfer occurs prior to the expiration of the Restricted Period, the
interest transferred will be held immediately thereafter through Euroclear or
CEDEL.

                  (h) Any beneficial interest in one of the Global Notes that is
transferred to a Person who takes delivery in the form of



   44


                                      -37-



an interest in another Global Note shall, upon transfer, cease to be an interest
in such Global Note and become an interest in such other Global Note and,
accordingly, shall thereafter be subject to all transfer restrictions and other
procedures applicable to beneficial interests in such other Global Note for as
long as it remains such an interest.

                  (i) The Holder of any Global Note may grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

Section 2.16.  Special Transfer Provisions.
               ----------------------------

                  (a) TRANSFERS TO NON-QIB INSTITUTIONAL ACCREDITED INVESTORS
AND NON-U.S. PERSONS. The following provisions shall apply with respect to the
registration of any proposed transfer of a Note constituting a Restricted Note
to any Institutional Accredited Investor which is not a QIB or to any Non-U.S.
Person:

                    (i) the Registrar shall register the transfer of any Note
         constituting a Restricted Note, whether or not such Note bears the
         Private Placement Legend, if (x) the requested transfer is after July
         2, 1999 or such other date as such Note shall be freely transferable
         under Rule 144 as certified in an Officers' Certificate or (y) (1) in
         the case of a transfer to an Institutional Accredited Investor which is
         not a QIB (excluding Non-U.S. Persons), the proposed transferee has
         delivered to the Registrar a certificate substantially in the form of
         EXHIBIT E hereto or (2) in the case of a transfer to a Non-U.S. Person
         (including a QIB), the proposed transferor has delivered to the
         Registrar a certificate substantially in the form of EXHIBIT F hereto;
         PROVIDED that in the case of a transfer of a Note bearing the Private
         Placement Legend for a Note not bearing the Private Placement Legend,
         the Registrar has received an Officers' Certificate authorizing such
         transfer; and

                   (ii) if the proposed transferor is an Agent Member holding a
         beneficial interest in a Global Note, upon receipt by the Registrar of
         (x) the certificate, if any, required by paragraph (i) above and (y)
         instructions given in accordance with the Depository's and the
         Registrar's procedures,

whereupon (a) the Registrar shall reflect on its books and records the date and
(if the transfer does not involve a transfer of outstanding Physical Notes) a
decrease in the principal amount



   45


                                      -38-



of a Global Note in an amount equal to the principal amount of the beneficial
interest in a Global Note to be transferred, and (b) the Company shall execute
and the Trustee shall authenticate and make available for delivery one or more
Physical Notes of like tenor and amount.

                  (b) Transfers to QIBs. The following provisions shall apply
with respect to the registration of any proposed registration of transfer of a
Note constituting a Restricted Note to a QIB (excluding transfers to Non-U.S.
Persons):

                    (i) the Registrar shall register the transfer if such
         transfer is being made by a proposed transferor who has checked the box
         provided for on such Holder's Note stating, or has otherwise advised
         the Company and the Registrar in writing, that the sale has been made
         in compliance with the provisions of Rule 144A to a transferee who has
         signed the certification provided for on such Holder's Note stating, or
         has otherwise advised the Company and the Registrar in writing, that it
         is purchasing the Note for its own account or an account with respect
         to which it exercises sole investment discretion and that it and any
         such account is a QIB within the meaning of Rule 144A, and is aware
         that the sale to it is being made in reliance on Rule 144A and
         acknowledges that it has received such information regarding the
         Company as it has requested pursuant to Rule 144A or has determined not
         to request such information and that it is aware that the transferor is
         relying upon its foregoing representations in order to claim the
         exemption from registration provided by Rule 144A; and

                   (ii) if the proposed transferee is an Agent Member, and the
         Notes to be transferred consist of Physical Notes which after transfer
         are to be evidenced by an interest in the Global Note, upon receipt by
         the Registrar of instructions given in accordance with the Depository's
         and the Registrar's procedures, the Registrar shall reflect on its
         books and records the date and an increase in the principal amount of
         the Global Note in an amount equal to the principal amount of the
         Physical Notes to be transferred, and the Trustee shall cancel the
         Physical Notes so transferred.

                  (c) PRIVATE PLACEMENT LEGEND. Upon the registration of
transfer, exchange or replacement of Notes not bearing the Private Placement
Legend, the Registrar shall deliver Notes that do not bear the Private Placement
Legend. Upon the registration of transfer, exchange or replacement of Notes
bearing the Private



   46


                                      -39-



Placement Legend, the Registrar shall deliver only Notes that bear the Private
Placement Legend unless (i) it has received the Officers' Certificate required
by paragraph (a)(i)(y) of this Section 2.16, (ii) there is delivered to the
Registrar an Opinion of Counsel reasonably satisfactory to the Company and the
Trustee to the effect that neither such legend nor the related restrictions on
transfer are required in order to maintain compliance with the provisions of the
Securities Act or (iii) such Note has been sold pursuant to an effective
registration statement under the Securities Act and the Registrar has received
an Officers' Certificate from the Company to such effect.

                  (d) GENERAL. By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture.

                  The Registrar shall retain for a period of two years copies of
all letters, notices and other written communications received pursuant to
Section 2.15 or this Section 2.16. The Company shall have the right to inspect
and make copies of all such letters, notices or other written communications at
any reasonable time upon the giving of reasonable notice to the Registrar.

Section 2.17.  Computation of Interest.
               -----------------------

                  Interest on the Notes shall be computed on the basis of a
360-day year of twelve 30-day months.


                                    ARTICLE 3

                                   REDEMPTION


Section 3.01.  Election to Redeem; Notices to Trustee.
               ---------------------------------------

                  If the Company elects to redeem Notes pursuant to paragraph 5
of the Notes, at least 45 days prior to the Redemption Date (unless a shorter
notice shall be agreed to in writing by the Trustee) but not more than 65 days
before the Redemption Date, the Company shall notify the Trustee in writing of
the Redemption Date, the principal amount of Notes to be redeemed and the
redemption price, and deliver to the Trustee an Officers' Certificate and an
Opinion of Counsel stating that such



   47


                                      -40-



redemption will comply with the conditions contained in paragraph 5 of the
Notes.

                  If fewer than all the Notes 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 less than 15 days after the date of
notice to the Trustee (unless a shorter period shall be acceptable to the
Trustee). Any such notice may be canceled by notice in writing to the Trustee 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 by Trustee of Notes To Be Redeemed.
               ---------------------------------------------

                  In the event that fewer than all of the Notes are to be
redeemed, the Trustee shall select the Notes to be redeemed, if the Notes are
listed on a national securities exchange, in accordance with the rules of such
exchange or, if the Notes are not so listed, either on a pro rata basis or by
lot, or such other method as it shall deem fair and equitable; PROVIDED,
HOWEVER, that if a partial redemption is made with the proceeds of a Public
Equity Offering, selection of the Notes or portion thereof for redemption shall
be made by the Trustee on a PRO RATA basis to the extent practical, unless such
a method is prohibited. The Trustee shall promptly notify the Company of the
Notes selected for redemption and, in the case of any Notes selected for partial
redemption, the principal amount thereof to be redeemed. The Trustee may select
for redemption portions of the principal of the Notes that have denominations
larger than $1,000. Notes and portions thereof the Trustee selects shall be
redeemed in amounts of $1,000 or whole multiples of $1,000. For all purposes of
this Indenture unless the context otherwise requires, provisions of this
Indenture that apply to Notes called for redemption also apply to portions of
Notes called for redemption.

Section 3.03.  Notice of Redemption.
               ---------------------

                  At least 30 days, and no more than 60 days, before a
Redemption Date, the Company shall mail, or cause to be mailed, a notice of
redemption by first-class mail to each Holder of Notes to be redeemed at his or
her last address as the same appears on the registry books maintained by the
Registrar pursuant to Section 2.03 hereof.

                  The notice shall identify the Notes to be redeemed (including
the CUSIP numbers thereof) and shall state:




   48


                                      -41-



                  (1) the Redemption Date;

acquisition of Capital Stock or property of another person) used or useful in
businesses similar or ancillary to the business of the Company or Restricted
Subsidiary as conducted at the time of such Asset Sale, provided that such

If an Excess Proceeds Offer is not fully



   57


                                      -50-

                  (4) that any Note accepted for payment pursuant to the Excess
         Proceeds Offer shall cease to accrue interest on and after the Purchase
         Date and the deposit of the purchase price with the Trustee;

                  (5) that Holders electing to have a Note purchased pursuant to

         Purchase Date;

                  (6) that Holders will be entitled to withdraw their election

         of the Holder, the principal amount of the Note the Holder delivered
         for purchase and a statement that such Holder is withdrawing his
         election to have the Note purchased;

                  (7) that, if the aggregate principal amount of Notes
         surrendered by Holders exceeds the Available Asset Sale Proceeds, the
         Company shall select the Notes to be purchased on a pro rata basis
         (with such adjustments as may be deemed appropriate by the Company so
         that only Notes in denominations of $1,000, or integral multiples
         thereof, shall be purchased); and

                  (8) that Holders whose Notes were purchased only in part will
         be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered.

extent lawful, accept for payment, on a pro rata basis to the extent necessary,
Notes or portions thereof tendered pursuant to the Excess Proceeds Offer,

price plus accrued interest, if any, on the Notes to be purchased and deliver to

Guarantor shall endorse the guarantee thereon and the Trustee shall authenticate
and mail or make available for delivery such new Note to such Holder equal in
principal amount to any unpurchased portion of the Note surrendered. Any Note
not so accepted shall be promptly mailed or delivered by the Company to the
Holder thereof. The Company will publicly announce the results of the Excess
Proceeds Offer on the Purchase Date by sending a press release to the Dow Jones
News Service or similar business news service in the United States. If an Excess
Proceeds Offer is not fully subscribed, the Company may retain that portion of
the Available Asset Sale Proceeds not required to repurchase Notes.

                  (a) The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, enter



   59


                                      -52-



into or suffer to exist any transaction or series of related transactions
(including, without limitation, the sale, purchase, exchange or lease of assets,
property or services) with any Affiliate (including entities in which the
Company or any of its Restricted Subsidiaries own a minority interest) or holder
of 10% or more of the Common Stock of the Company (an "AFFILIATE TRANSACTION")
or extend, renew, waive or otherwise modify the terms of any Affiliate
Transaction entered into prior to the Issue Date unless (i) such Affiliate
Transaction is between or among the Company and its Wholly-Owned Restricted
Subsidiaries; or (ii) the terms of such Affiliate Transaction are fair and
reasonable to the Company or such Restricted Subsidiary, as the case may be, and
the terms of such Affiliate Transaction are at least as favorable as the terms
which could be obtained by the Company or such Restricted Subsidiary, as the
case may be, in a comparable transaction made on an arm's-length basis between
unaffiliated parties. In any Affiliate Transaction involving an amount or having
a value in excess of $1.0 million which is not permitted under clause (i) above,
the Company must obtain a resolution of the Board of Directors certifying that
such Affiliate Transaction complies with clause (ii) above. In transactions with
a value in excess of $5.0 million which are not permitted under clause (i)
above, the Company must obtain a written opinion as to the fairness of such a
transaction from a nationally recognized independent investment banking firm.

                  (b) The foregoing provisions will not apply to (i) any
Restricted Payment that is not prohibited by Section 4.09 hereof, (ii) any
transaction, approved by the Board of Directors of the Company, with an officer
or director of the Company or of any Subsidiary in his or her capacity as
officer or director entered into in the ordinary course of business, (iii) any
transactions with KECC for advisory services to the extent the payment for such
services do not exceed $200,000 per year, (iv) customary banking transactions
with an Affiliate of KECC, (v) reasonable fees and compensation paid to and
indemnity provided on behalf of, officers, directors, employees or consultants
of the Company or any Subsidiary of the Company as determined in good faith by
the Company's Board of Directors, or (vi) transactions exclusively between or
among the Company and any of its Restricted Subsidiaries or exclusively between
or among such Restricted Subsidiaries, provided such transactions are not
otherwise prohibited by this Indenture.

Section 4.12.  Limitations on Liens.
               ---------------------

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, create, incur or otherwise cause or



   60


                                      -53-



suffer to exist or become effective any Liens of any kind (other than Permitted
Liens) upon any property or asset of the Company or any Restricted Subsidiary or
any shares of stock or debt of any Restricted Subsidiary which owns property or
assets, now owned or hereafter acquired, unless (i) if such Lien secures
Indebtedness which is pari passu with the Notes, then the Notes are secured on
an equal and ratable basis with the obligations so secured until such time as
such obligation is no longer secured by a Lien or (ii) if such Lien secures
Indebtedness which is subordinated to the Notes, any such Lien shall be
subordinated to a Lien on such property or asset or shares of stock or debt
granted to the holders of the Notes to the same extent as such subordinated
Indebtedness is subordinated to the Notes.

Section 4.13.              Limitations on Investments.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, make any Investment other than (i) a Permitted
Investment or (ii) an Investment that is made as a Restricted Payment in
compliance with Section 4.09 hereof, after the Issue Date.

Section 4.14.  Limitation on Creation of Subsidiaries.
               ---------------------------------------

Restricted Subsidiaries to create or acquire, any Subsidiary other than (i) a
Restricted Subsidiary existing as of the date of the Indenture, (ii) a
Restricted Subsidiary conducting a business similar or reasonably related to the
business of the Company and its Subsidiaries on the Issue Date, or (iii) an
Unrestricted Subsidiary; PROVIDED, HOWEVER, that each Restricted Subsidiary
organized under the laws of the United States or any State thereof or the
District of Columbia acquired or created pursuant to clause (ii) shall, at the
time it has either assets or shareholder's equity in excess of $10,000, execute
a guarantee, in the form attached hereto as EXHIBIT G and reasonably
satisfactory in form and substance to the Trustee (and with such documentation
relating thereto as the Trustee shall require, including, without limitation a
supplement or amendment to this Indenture and an Opinion of Counsel as to the
enforceability of such Guarantee).

               -----------------------------------------------

to the fair market

               -------------

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary to (a)(i) pay dividends or make any other
distributions to the Company or any of its Restricted Subsidiaries (A) on its
Capital Stock or (B) with respect to any other interest or participation in, or
measured by, its profits, or (ii) pay any Indebtedness owed to the Company or
any of its Restricted Subsidiaries, (b) make loans or advances or capital
contributions to the Company or any of its Restricted Subsidiaries or (c)
transfer any of its properties or assets to the Company or any of its Restricted

the Revolving Credit Facility, (ii) this Indenture, the Notes and the
Guarantees, if applicable, (iii) applicable law, (iv) any instrument governing
Indebtedness or Capital Stock of a Person acquired by the Company or any of its
Restricted Subsidiaries or of any Person that becomes a Restricted Subsidiary as
in effect at the time of such acquisition or such Person becoming a Restricted
Subsidiary (except to the extent such Indebtedness was incurred in connection
with or in contemplation of such acquisition or such Person becoming a
Restricted Subsidiary), which encumbrance or restriction is not applicable to
any Person, or the properties or assets of any Person, other than the Person, or
the property or assets of the Person (including any Subsidiary of the Person),
so acquired, provided that the EBITDA of such Person is not taken into account
(to the extent of such restriction) in determining whether any financing or
Restricted Payment in connection with such acquisition was permitted by the
terms of the Indenture, (v) customary nonassignment provisions in leases or
other agreements entered into in the ordinary course of business and consistent
with past practices, (vi) Refinancing Indebtedness; provided that such
restrictions are in the aggregate no more restrictive than those contained in
the agreements governing the Indebtedness being extended, refinanced, renewed,
replaced, defeased or refunded or (vii) customary restrictions in security
agreements, liens or mortgages securing Indebtedness of the



   62


                                      -55-



Company or a Restricted Subsidiary to the extent such restrictions restrict the
transfer of the property subject to such security agreements and mortgages.

Section 4.17.  Payments for Consent.
               ---------------------

                  Neither the Company nor any of its Subsidiaries shall,
directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, including out-of-pocket costs and expenses,
to any Holder of any Notes for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Notes

its legal existence, and the corporate, partnership or other existence of each
Restricted Subsidiary, in accordance with the respective organizational
documents (as the same may be amended from time to time) of each Restricted
Subsidiary and the rights (charter and statutory), licenses and franchises of
the Company and its Restricted Subsidiaries; PROVIDED, HOWEVER, that the Company
shall not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Restricted Subsidiaries
if the Board of Directors of the Company shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not
adverse in any material respect to the Holders.

Section 4.19.  Change of Control.
               ------------------

                  (a) Within 20 days of the occurrence of a Change of Control,
the Company shall notify the Trustee in writing of such occurrence and shall
make an offer to purchase (the "CHANGE OF CONTROL OFFER") the outstanding Notes
at a purchase price equal to 101% of the principal amount thereof plus any
accrued and unpaid interest thereon to the Change of Control Payment Date (as
hereinafter defined) (such applicable purchase price being hereinafter referred
to as the "CHANGE OF CONTROL PURCHASE PRICE") in accordance with the procedures
set forth below.




   63


                                      -56-



                  If the Revolving Credit Facility is in effect, or any amounts
are owing thereunder, at the time of the occurrence of a Change of Control,
prior to the mailing of the notice to Holders described in paragraph (b) below,
but in any event within 30 days following any Change of Control, the Company
covenants to (i) repay in full all obligations under the Revolving Credit
Facility or offer to repay in full all obligations under or in respect of the
Revolving Credit Facility and repay the obligations under or in respect of the
Revolving Credit Facility of each lender who has accepted such offer or (ii)
obtain the requisite consent under the Revolving Credit Facility to permit the
repurchase of the Notes pursuant to this Section 4.19. The Company must first
comply with the covenant described in the preceding sentence before it may
commence a Change of Control Offer in the event of a Change of Control; PROVIDED
that the Company's failure to comply with the covenant described in the
preceding sentence constitutes an Event of Default described in clause (3) under
Section 6.01 hereof if not cured within 30 days after the notice required by
such clause.

                  (b) Within 30 days of the occurrence of a Change of Control,
the Company also shall (i) cause a notice of the Change of Control Offer to be
sent at least once to the Dow Jones News Service or similar business news
service in the United States and (ii) send by first-class mail, postage prepaid,
to the Trustee and to each Holder of the Notes, at the address appearing in the
register maintained by the Registrar of the Notes, a notice stating:

                  (1) that the Change of Control Offer is being made pursuant to
         this Section 4.19 and that all Notes tendered will be accepted for
         payment, and otherwise subject to the terms and conditions set forth
         herein;

                  (2) the Change of Control Purchase Price and the purchase date
         (which shall be a Business Day no earlier than 30 Business Days from
         the date such notice is mailed (the "CHANGE OF CONTROL PAYMENT DATE"));

                  (3) that any Note not tendered will continue to accrue
         interest;

                  (4) that, unless the Company defaults in the payment of the
         Change of Control Purchase Price, any Notes accepted for payment
         pursuant to the Change of Control Offer shall cease to accrue interest
         after the Change of Control Payment Date;




   64


                                      -57-



                    (5) that Holders accepting the offer to have their Notes
         purchased pursuant to a Change of Control Offer will be required to
         surrender the Notes, with the form entitled "Option of Holder to Elect
         Purchase" on the reverse of the Note completed, to a depository, if
         appointed, or the Paying Agent at the address specified in the notice
         prior to the close of business on the Business Day preceding the Change
         of Control Payment Date;

                    (6) that Holders will be entitled to withdraw their
         acceptance if the depository or Paying Agent receives, not later than
         the close of business on the third Business Day preceding the Change of
         Control Payment Date, a telegram, telex, facsimile transmission or
         letter setting forth the name of the Holder, the principal amount of
         the Notes delivered for purchase, and a statement that such Holder is
         withdrawing his election to have such Notes purchased;

                    (7) that Holders whose Notes are being purchased only in
         part will be issued new Notes equal in principal amount to the
         unpurchased portion of the Notes surrendered, PROVIDED that each Note
         purchased and each such new Note issued shall be in an original
         principal amount in denominations of $1,000 and integral multiples
         thereof;

                    (8) any other procedures that a Holder must follow to accept
         a Change of Control Offer or effect withdrawal of such acceptance; and

                    (9) the name and address of the depository or Paying Agent.

                  On the Change of Control Payment Date, the Company shall, to
the extent lawful, (i) accept for payment Notes or portions thereof tendered
pursuant to the Change of Control Offer, (ii) deposit with the depository or
Paying Agent money sufficient to pay the purchase price of all Notes or portions
thereof so tendered and (iii) deliver or cause to be delivered to the Trustee
Notes so accepted together with an Officers' Certificate stating the Notes or
portions thereof tendered to the Company. The Paying Agent shall promptly mail
to each Holder of Notes so accepted payment in an amount equal to the purchase
price for such Notes, and the Company shall execute and issue, and the Trustee
shall promptly authenticate and mail to such Holder, a new Note equal in
principal amount to any unpurchased portion of the Notes surrendered; PROVIDED
that each such new Note shall be issued in an original principal amount in
denominations of $1,000 and integral multiples thereof.


   65


                                      -58-



                  (c) (A) If either Company or any Subsidiary thereof has issued
any outstanding (i) Indebtedness that is subordinated in right of payment to the
Notes or (ii) Preferred Stock, and the Company or such Subsidiary is required to
make a Change of Control offer or to make a distribution with respect to such
subordinated Indebtedness or Preferred Stock in the event of a change of
control, the Company shall not consummate any such offer or distribution with
respect to such subordinated Indebtedness or Preferred Stock until such time as
the Company shall have paid the Change of Control Purchase Price in full to the
Holders of Notes that have accepted the Company's Change of Control Offer and
shall otherwise have consummated the Change of Control Offer made to Holders of
the Notes and (B) the Company will not issue Indebtedness that is subordinated
in right of payment to the Notes or Preferred Stock with change of control
provisions requiring the payment of such Indebtedness or Preferred Stock prior
to the payment of the Notes in the event of a Change in Control under this
Indenture.

                  In the event that a Change of Control occurs and the Holders
of Notes exercise their right to require the Company to purchase Notes, if such
purchase constitutes a "tender offer" for purposes of Rule 14e-1 under the
Exchange Act at that time, the Company will comply with the requirements of Rule
14e-1 as then in effect with respect to such repurchase.

necessary equipment, and shall cause to be made all repairs, renewals,
replacements and betterments thereto.

                  (b) The Company shall, and shall cause each of its Restricted
Subsidiaries to, maintain insurance in such amounts and covering such risks as

business of the Company and each



   66


                                      -59-



Subsidiary of the Company, in accordance with GAAP consistently applied to the
Company and its Subsidiaries taken as a whole.

                  (d) The Company shall, and shall cause each of its
Subsidiaries to, comply with all statutes, laws, ordinances or government rules
and regulations to which they are subject, non-compliance with which would
materially adversely affect the business, prospects, earnings, properties,
assets or financial condition of the Company and their Subsidiaries taken as a
whole.

               ---------------------------------

                           (B) appoints a Custodian of either of the Company or
                  any Restricted Subsidiary or for all or substantially all of
                  the property of either of the Company or any Restricted
                  Subsidiary, or

                           (C) orders the liquidation of either of the Company 
                  or any Restricted Subsidiary,

         and the order or decree remains unstayed and in effect for
         60 days.

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

                  Subject to Sections 7.01 and 7.02, the Trustee shall not be
charged with knowledge of any Default, Event of Default, Change of Control or
Asset Sale or the requirement for payment of Additional Interest unless written
notice thereof shall have been



   70


                                      -63-



given to a Responsible Officer at the Corporate Trust Office of the Trustee by
the Company or any other Person.

Section 6.02.  Acceleration.
               -------------

                  If an Event of Default (other than an Event of Default arising
under Section 6.01(6) or (7) with respect to the Company) occurs and is
continuing, the Trustee by notice to the Company, or the Holders of not less
than 25% in aggregate principal amount of the Notes then outstanding may by
written notice to the Company and the Trustee declare to be immediately due and
payable the entire principal amount of all the Notes then outstanding plus
accrued but unpaid interest to the date of acceleration; PROVIDED, HOWEVER, that
after such acceleration but before a judgment or decree based on such
acceleration is obtained by the Trustee, the Holders of a majority in aggregate
principal amount of the outstanding Notes may rescind and annul such
acceleration and its consequences if all existing Events of Default, other than
the nonpayment of accelerated principal, premium, if any, or interest that has
become due solely because of the acceleration, have been cured or waived and if
the rescission would not conflict with any judgment or decree. No such
rescission shall affect any subsequent Default or impair any right consequent
thereto. In case an Event of Default specified in Section 6.01(6) or (7) with
respect to the Company occurs, such principal, premium, if any, and interest
amount with respect to all of the Notes shall be due and payable immediately
without any declaration or other act on the part of the Trustee or the Holders
of the Notes.

Section 6.03.  Other Remedies.
               ---------------

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of, or premium, if any, and interest on the Notes or to
enforce the performance of any provision of the Notes or this Indenture and may
take any necessary action requested of it as Trustee to settle, compromise,
adjust or otherwise conclude any proceedings to which it is a party.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Noteholder 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.



   71


                                      -64-



No remedy is exclusive of any other remedy. All available remedies are
cumulative.

Section 6.04.  Waiver of Past Defaults and Events of Default.
               ----------------------------------------------

                  Subject to Sections 6.02, 6.08 and 8.02 hereof, the Holders of
a majority in principal amount of the Notes then outstanding have the right to
waive any existing Default or Event of Default or compliance with any provision
of this Indenture or the Notes. Upon any such waiver, such Default shall cease
to exist, and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other Default or Event of Default or impair any right
consequent thereto.

Section 6.05.  Control by Majority.
               -------------------

                  The Holders of a majority in principal amount of the Notes
then outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee by this Indenture. The Trustee, however, may
refuse to follow any direction that conflicts with law or this Indenture or that
the Trustee determines may be unduly prejudicial to the rights of another
Noteholder not taking part in such direction, and the Trustee shall have the
right to decline to follow any such direction if the Trustee, being advised by
counsel, determines that the action so directed may not lawfully be taken or if
the Trustee in good faith shall, by a Responsible Officer, determine that the
proceedings so directed may involve it in personal liability; PROVIDED that the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

Section 6.06.  Limitation on Suits.
               --------------------

                  Subject to Section 6.08 below, a Noteholder may not institute
any proceeding or pursue any remedy with respect to this Indenture or the Notes
unless:

                  (1) the Holder gives to the Trustee written notice of a
         continuing Event of Default;

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




   72


                                     -65-



                  (3) such Holder or Holders offer and if requested provide to
         the Trustee indemnity reasonably satisfactory to the Trustee 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, and, if requested,
         provision of, indemnity; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60 day period by the Holders of a
         majority in aggregate principal amount of the Notes then outstanding.

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

Section 6.07.  No Personal Liability of Directors, Officers, Employees and 
               -----------------------------------------------------------
               Stockholders.
               -------------

                  No director, officer, employee, incorporator or stockholder of
the Company or any Guarantor shall have any liability for any obligations of the
Company or the Guarantors under the Notes, the Guarantees, if any, or this
Indenture or for a claim based on, in respect of, or by reason of such
obligations or their creation. Each Holder of the Notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

Section 6.08.  Rights of Holders To Receive Payment.
               -------------------------------------

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of principal of, or premium, if
any, and interest of the Note (including Additional Interest) on or after the
respective due dates expressed in the Note, or to bring suit for the enforcement
of any such payment on or after such respective dates, is absolute and
unconditional and shall not be impaired or affected without the consent of the
Holder.

Section 6.09.  Collection Suit by Trustee.
               ---------------------------

                  If an Event of Default in payment of principal, premium or
interest specified in Section 6.01(1) or (2) hereof occurs and is continuing,
the Trustee may recover judgment in its own name and as trustee of an express
trust against the Company or the Guarantors (or any other obligor on the Notes)
for the whole amount of unpaid principal and accrued interest remaining unpaid,



   73


                                      -66-



together with interest on overdue principal and, to the extent that payment of
such interest is lawful, interest on overdue installments of interest, in each
case at the rate set forth in the Notes, and such further amounts as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

Section 6.10.  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 (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 hereof) and the Noteholders allowed
in any judicial proceedings relative to the Company or the Guarantors (or any
other obligor upon the Notes), its creditors or its property and shall be
entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same after
deduction of its charges and expenses to the extent that any such charges and
expenses are not paid out of the estate in any such proceedings and any
custodian in any such judicial proceeding is hereby authorized by each
Noteholder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the
Noteholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Noteholder any plan or reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such
proceedings.

Section 6.11.  Priorities.
               -----------

                  If the Trustee collects any money pursuant to this Article 6,
it shall pay out the money in the following order:

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




   74


                                      -67-



                  SECOND: to Noteholders for amounts due and unpaid on the Notes
         for principal, premium, if any, and interest (including Additional
         Interest, if any) as to each, ratably, without preference or priority
         of any kind, according to the amounts due and payable on the Notes; and

                  THIRD: to the Company or, to the extent the Trustee collects
         any amount from any Guarantor, to such Guarantor.

                  The Trustee may fix a record date and payment date for any
payment to Noteholders pursuant to this Section 6.11.

Section 6.12.  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 6.12 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.08 hereof or a suit by Holders of more than 10% in
principal amount of the Notes then outstanding.

Section 6.13.  Restoration of Rights and Remedies.
               -----------------------------------

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                                     TRUSTEE


Section 7.01.  Duties of Trustee.
               ------------------

                  (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of 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 man would exercise or use under the same circumstances in the conduct of
his own affairs.

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

                  (1) The Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others.

                  (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 but, in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture (but need not confirm or investigate the accuracy of
         mathematical calculations or other facts stated therein).

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

                  (1) This paragraph does not limit the effect of paragraph (b)
         of this Section 7.01.

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

                  (3) The Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in



   76


                                      -69-



         accordance with a direction received by it pursuant to Sections 6.02 or
         6.05 hereof.

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

                  (d) Whether or not therein expressly so provided, paragraphs
(a), (b), (c), (e) and (f) of this Section 7.01 shall govern every provision of
this Indenture that in any way relates to the Trustee.

                  (e) The Trustee may refuse to perform any duty or exercise any
right or power unless it receives indemnity satisfactory to it in its sole
discretion against any loss, liability, expense or fee.

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

Section 7.02.  Rights of Trustee.
               ------------------

                  Subject to Section 7.01 hereof:

                  (1) The Trustee may rely on any document reasonably 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.

                  (2) Before the Trustee acts or refrains from acting, it may
         require an Officers' Certificate or an Opinion of Counsel, or both,
         which shall conform to the provisions of Section 11.05 hereof. The
         Trustee shall be protected and shall not be liable for any action it
         takes or omits to take in good faith in reliance on such certificate or
         opinion.

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




   77


                                      -70-



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

                  (5) The Trustee may consult with counsel of its selection, and
         the advice or opinion of such counsel as to matters of law shall be
         full and complete authorization and protection from liability in
         respect of any action taken, omitted or suffered by it hereunder in
         good faith and in accordance with the advice or opinion of such
         counsel.

                  (6) The Trustee shall be under no obligation to exercise any
         of the rights or powers created in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction.

                  (7) The Trustee shall not be bound to make any investigation
         into the facts or matters stated in any document, but the Trustee, in
         its discretion, may make such further inquiry or investigation into
         such facts or matters as it may see fit.

Section 7.03.  Individual Rights of Trustee.
               -----------------------------

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may make loans to, accept deposits from,
perform services for or otherwise deal with the either of the Company or any
Guarantor, or any Affiliates thereof, with the same rights it would have if it
were not Trustee. Any Agent may do the same with like rights. The Trustee,
however, shall be subject to Sections 7.10 and 7.11 hereof.

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 Notes, it
shall not be accountable for the Company's use of the proceeds from the sale of
Notes or any money paid to the Company pursuant to the terms of this Indenture
and it shall not be responsible for any statement in the Notes or this Indenture
other than its 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 Noteholder notice of the Default
within 90 days after it occurs. Except in the case of a Default in payment of
the principal of, or premium, if any, or interest on any Note, the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in
good faith determine(s) that withholding the notice is in the interests of the
Noteholders.

Section 7.06.  Reports by Trustee to Holders.
               ------------------------------

                  If required by TIA Section 313(a), within 60 days after May 
15 of any year, commencing May 15, 1998, the Trustee shall mail to each
Noteholder a brief report dated as of such May 15 that complies with TIA
Section 313(a). The Trustee also shall comply with TIA Section 313(b)(2). The
Trustee shall also transmit by mail all reports as required by TIA Section
313(c) and TIA Section 313(d).

                  A copy of each report at the time of its mailing to
Noteholders shall be filed with the SEC and each stock exchange on which the
Notes are listed. The Company shall promptly notify the Trustee when the Notes
are listed on any stock exchange.

Section 7.07.  Compensation and Indemnity.
               ---------------------------

                  The Company and the Guarantors shall pay to the Trustee and
Agents from time to time such compensation as shall be agreed in writing between
the Company and the Trustee for its services hereunder (which compensation shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust). The Company and the Guarantors shall reimburse the
Trustee and Agents promptly upon request for all reasonable disbursements,
expenses and advances incurred or made by it, including costs of collection, in
connection with its duties under this Indenture, including the reasonable
compensation, disbursements and expenses of the Trustee's agents, accountants
and counsel.

                  The Company and the Guarantors shall indemnify each of the
Trustee and any predecessor Trustee for, and hold each of them harmless against,
any and all loss, damage, claim, liability or expense, including without
limitation taxes (other than taxes based on the income of the Trustee or such
Agent) and reasonable attorneys' fees and expenses incurred by each of them in
connection with the acceptance or performance of its duties under this Indenture
and the enforcement of this Indenture (including



   79


                                      -72-



this Section 7.07) against the Company and any Guarantor, including the
reasonable costs and expenses of defending itself against any claim or liability
in connection with the exercise or performance of any of its powers or duties
hereunder (including, without limitation, settlement costs). The Trustee or
Agent shall notify the Company and the Guarantors in writing promptly of any
claim asserted against the Trustee or Agent for which it may seek indemnity.
However, the failure by the Trustee or Agent to so notify the Company and the
Guarantors shall not relieve the Company and Guarantors of their obligations
hereunder.

                  Notwithstanding the foregoing, the Company and the Guarantors
need not reimburse the Trustee for any expense or indemnify it against any loss
or liability incurred by the Trustee through its negligence or bad faith. To
secure the payment obligations of the Company and the Guarantors in this Section
7.07, the Trustee shall have a lien prior to the Notes on all money or property
held or collected by the Trustee except such money or property held in trust to
pay principal of and interest on particular Notes. The Trustee's right to
receive payment of any amounts under this Section 7.07 shall not be subordinate
to any other liability or indebtedness of the Company or the Guarantors. The
obligations of the Company and the Guarantors under this Section 7.07 to
compensate and indemnify the Trustee, Agents and each predecessor Trustee and to
pay or reimburse the Trustee, Agents and each predecessor Trustee for expenses,
disbursements and advances shall be joint and several liabilities of the Company
and each of the Guarantors and shall survive the satisfaction and discharge of
this Indenture, including any termination or rejection hereof under any
Bankruptcy Law.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(6) or (7) hereof occurs, the expenses
and the compensation for the services (including the fees and expenses of its
agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law.

                  For purposes of this Section 7.07, the term "Trustee" shall
include any trustee appointed pursuant to Article 9.

Section 7.08.  Replacement of Trustee.
               -----------------------

                  The Trustee may resign by so notifying the Company and the
Guarantors in writing. The Holders of a majority in principal amount of the
outstanding Notes may remove the Trustee by notifying the Company and the
removed Trustee in writing and



   80


                                      -73-



may appoint a successor Trustee with the Company's written consent, which
consent shall not be unreasonably withheld. The Company may remove the Trustee
at its election if:

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

                  (2) the Trustee is adjudged a bankrupt or an insolvent;

         Trustee or its property; or

                  (4) the Trustee otherwise becomes incapable of acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee.

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

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

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately following
such delivery, the retiring Trustee shall, subject to its rights under Section
7.07 hereof, transfer all property held by it as Trustee to the successor
Trustee (provided that the amounts owing to the Trustee hereunder have been paid
in full), 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. A successor Trustee shall mail
notice of its succession to each Noteholder. Notwithstanding replacement of the
Trustee pursuant to this Section 7.08, the Company obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee.

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS


Section 8.01.  Without Consent of Holders.
               ---------------------------

                  The Company and the Guarantors, if any, when authorized by a
Board Resolution of each of them, and the Trustee may amend, waive or supplement
this Indenture or the Notes without notice to or consent of any Noteholder:

                  (1) to comply with Section 5.01 hereof;

                  (2) to provide for uncertificated Notes in addition to or in

                  (3) to comply with any requirements of the SEC under the TIA;

                  (4) to cure any ambiguity, defect or inconsistency;

                  The Trustee is hereby authorized to join with the Company and
the Guarantors, if any, in the execution of any supplemental indenture
authorized or permitted by the terms of this Indenture and to make any further
appropriate agreements and stipulations which may be therein contained, but the
Trustee



   83


                                      -76-



shall not be obligated to enter into any such supplemental indenture which
adversely affects its own rights, duties or immunities under this Indenture.

Section 8.02.  With Consent of Holders.
               ------------------------

                  The Company, the Guarantors, if any, and the Trustee may
modify, amend, waive or supplement this Indenture or the Notes with the written
consent of the Holders of not less than a majority in aggregate principal amount
of the outstanding Notes. The Holders of not less than a majority in aggregate
principal amount of the outstanding Notes may waive compliance in a particular
instance by the Company or any Guarantor with any provision of this Indenture or
the Notes. Subject to Section 8.04, without the consent of each Noteholder
affected, however, an amendment, supplement or waiver, including a waiver
pursuant to Section 6.04, may not:

                  (1) reduce the principal amount of outstanding Notes whose
         Holders must consent to an amendment, supplement or waiver to this
         Indenture or the Notes;

                  (2) reduce the rate of or change the time for payment of
         interest on any Note;

                  (3) reduce the principal of or premium on or change the stated
         maturity of any Note;

                  (4) make any Note payable in money other than that stated in
         the Note or change the place of payment from New York, New York;

                  (5) change the amount or time of any payment required by the
         Notes or reduce the premium payable upon any redemption of the Notes in
         accordance with Section 3.01 hereof, or change the time before which no
         such redemption may be made;

                  (6) waive a default in the payment of the principal of, or
         interest on, or redemption payment with respect to, any Note (including
         any obligation to make a Change of Control Offer or, after the
         Company's obligation to purchase Notes arises thereunder, an Excess
         Proceeds Offer or modify any of the provisions or definitions with
         respect to such offers);

                  (7) make any changes in Sections 6.04 or 6.08 hereof or this
         sentence of Section 8.02; or



   84


                                      -77-




                  (8) affect the ranking of the Notes or any Guarantee in a
         manner adverse to the Holders.

                  After a modification, amendment, supplement or waiver under
this Section 8.02 becomes effective, the Company shall mail to the Holders a
notice briefly describing the modification, amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such modification,
amendment, supplement or waiver.

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

Section 8.03.  Compliance with Trust Indenture Act.
               ------------------------------------

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

Section 8.04.  Revocation and Effect of Consents.
               ----------------------------------

                  Until a modification, amendment, supplement, waiver or other
action becomes effective, a consent to it by a Holder of a Note is a continuing
consent conclusive and binding upon such Holder and every subsequent Holder of
the same Note or portion thereof, and of any Note issued upon the transfer
thereof or in exchange therefor or in place thereof, even if notation of the
consent is not made on any such Note. Any such Holder or subsequent Holder,
however, may revoke the consent as to his Note or portion of a Note, if the
Trustee receives the written notice of revocation before the date the
modification, amendment, supplement, waiver or other action becomes effective.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to consent to any
modification, amendment, supplement, or waiver. If a record date is fixed, then,
notwithstanding the preceding paragraph, those Persons who were Holders at such
record date (or their duly designated proxies), and only such Persons, shall be
entitled to consent to such modification, amendment, supplement, or waiver or to
revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date. No such consent shall be valid or effective for
more than 90 days after such record date unless the consent of the requisite
number of Holders has been obtained.




   85


                                     -78-
                                      


                  After a modification, amendment, supplement, waiver or other
action becomes effective, it shall bind every Noteholder, unless it makes a
change described in any of clauses (1) through (8) of Section 8.02 hereof. In
that case the modification, amendment, supplement, waiver or other action shall
bind each Holder of a Note who has consented to it and every subsequent Holder
of a Note or portion of a Note that evidences the same debt as the consenting
Holder's Note.

Section 8.05.  Notation on or Exchange of Notes.
               ---------------------------------

                  If a modification, amendment, supplement or waiver changes the
terms of a Note, the Trustee may request the Holder of the Note deliver it to
the Trustee. In such case, the Trustee shall place an appropriate notation on
the Note about the changed terms and return it to the Holder. Alternatively, if
the Company or the Trustee so determines, the Company in exchange for the Note
shall issue, the Guarantors shall endorse, and the Trustee shall authenticate a
new Note that reflects the changed terms. Failure to make the appropriate
notation or issue a new Note shall not affect the validity and effect of such
amendment, supplement or waiver.

Section 8.06.  Trustee To Sign Amendments, etc.
               --------------------------------

                  The Trustee shall sign any modification, amendment, supplement
or waiver authorized pursuant to this Article 8 if the modification, amendment,
supplement or waiver 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 or refusing to sign such modification, amendment, supplement or
waiver the Trustee shall be entitled to receive and, subject to Section 7.01
hereof, shall be fully protected in relying upon an Officers' Certificate and an
Opinion of Counsel stating that such modification, amendment, supplement or
waiver is authorized or permitted by this Indenture and is a legal, valid and
binding obligation of the Company and the Guarantors, if any, enforceable
against each of them in accordance with its terms (subject to customary
exceptions). The Company or any Guarantor may not sign a modification, amendment
or supplement until the Board of Directors of the Company or such Guarantor, as
appropriate, approves it.

                  The Company and the Guarantors, if any, may terminate their
obligations under the Notes, the Guarantees, if any, and this Indenture, except
the obligations referred to in the last paragraph of this Section 9.01, if there
shall have been cancelled by the Trustee or delivered to the Trustee for

Notes that are asserted to have been destroyed, lost or stolen and that shall
have been replaced as provided in Section 2.07 hereof) and the Company has paid

Trustee.

                  After such delivery, the Trustee upon Company Request shall
acknowledge in writing the discharge of the Company's and the Guarantors'
obligations under the Notes, the Guarantees and this Indenture except for those
surviving obligations specified below.

                  Notwithstanding the satisfaction and discharge of this

hereof shall survive.

               -----------------

                  The Company may at its option, by Board Resolution of the
Board of Directors of the Company, be discharged from its obligations with
respect to the Notes and the Guarantors, if any, discharged from their
obligations under the Guarantees, if any, on the date the conditions set forth
in Section 9.04 below are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this
purpose, such Legal Defeasance means that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by the Notes and to have
satisfied all its other obligations under such Notes and this Indenture insofar
as such Notes are concerned (and the Trustee, at the expense of the Company,
shall, subject to Section 9.06 hereof, execute instruments in form and substance
reasonably satisfactory to the Trustee and Company acknowledging the same),
except for the following which shall survive until otherwise terminated or
discharged hereunder: (A) the rights of Holders of outstanding Notes to receive
solely from the trust funds described in Section 9.04 hereof and as more fully
set forth in such Section, payments in respect of the principal of,

duties, and immunities of the Trustee hereunder (including claims of, or
payments to, the Trustee under or pursuant to Section 7.07 hereof) and (D) this
Article 9. Subject to compliance with this Article 9, the Company may exercise
its option under this Section 9.02 with respect to the Notes notwithstanding the
prior exercise of its option under Section 9.03 below with respect to the Notes.

Section 9.03.  Covenant Defeasance.
               --------------------

                  At the option of the Company, pursuant to a Board Resolution
of the Board of Directors of the Company, the Company and the Guarantors, if

inclusive, and clause (a)(iii) of Section 5.01 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 9.04
hereof are satisfied (hereinafter, "COVENANT DEFEASANCE") and the Notes shall
thereafter be deemed to not be outstanding for purposes of any direction,
waiver, consent, declaration or act of the Holders (and the consequences
thereof) in connection with such covenants but shall continue to be outstanding
for all other purposes hereunder. For this purpose, such Covenant Defeasance
means that the Company and the Guarantors, if any, may omit to comply with and
shall have no liability in respect of any term, condition or limitation set
forth in any such specified Section or portion thereof, whether directly or
indirectly by reason of any reference elsewhere herein to any such specified
Section or portion thereof or by reason of any reference in any such specified
Section or portion thereof to any other provision herein or in any other
document, but the remainder of this Indenture and the Notes shall be unaffected
thereby.

         provisions of this Article 9 applicable to it) as funds in trust for
         the purpose of

         sufficient, in the opinion of a nationally-recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall

         ending on the day following the expiration of the longest preference
         period under any Bankruptcy Law applicable to the Company in respect of
         such deposit (it being understood that this condition shall not be
         deemed satisfied until the expiration of such period);

                  (3) such Legal Defeasance or Covenant Defeasance shall not
         cause the Trustee to have a conflicting interest for purposes of the
         TIA with respect to any securities of the Company;

                  (4) such Legal Defeasance or Covenant Defeasance shall not
         result in a breach or violation of, or constitute default under any

                                      -82-



                  (6) in the case of an election under Section 9.02 above, 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 to the effect that

         law with the effect that, and such opinion shall confirm that, the
         Holders of the outstanding Notes or Persons in their positions will not
         recognize income, gain or loss for Federal income tax purposes solely
         as a result of such Legal Defeasance and will be subject to Federal
         income tax on the same amounts, in the same manner, including as a
         result of prepayment, and at the same times as would have been the case
         if such Legal Defeasance had not occurred;

               Trust; Other Miscellaneous Provisions.
               --------------------------------------------------------------

                  All money and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee pursuant to Section 9.04 hereof in
respect of the outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent, to the Holders of such
Notes, of all sums due and to become due thereon in respect of principal,
premium, if any, and accrued interest, but such money need not be segregated
from other funds except to the extent required by law.

                  The Company and the Guarantors, if any, shall (on a joint and
several basis) pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the U.S. Government Obligations deposited
pursuant to Section 9.04 hereof or the principal, premium, if any, and interest
received in respect thereof other than any such tax, fee or other charge which

the Trustee shall deliver or pay to the Company from time to time upon an
Company Request any money or U.S. Government Obligations held by it as provided
in Section 9.04 hereof which, in the opinion of a nationally-recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

Section 9.06.  Reinstatement.
               --------------

                  If the Trustee or Paying Agent is unable to apply any money or
U.S. Government Obligations in accordance with Section 9.01, 9.02 or 9.03 hereof
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 obligations of the Company and any Guarantor under this
Indenture, the Notes and the Guarantees, if any, shall be revived and reinstated
as though no deposit had occurred pursuant to this Article 9 until such time as
the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 9.01 hereof; PROVIDED,
HOWEVER, that if the Company or the Guarantors



   91


                                                      -84-



have made any payment of principal of, premium, if any, or accrued interest on
any Notes because of the reinstatement of their obligations, the Company or the
Guarantors, as the case may be, shall be subrogated to the rights of the Holders
of such Notes to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

Section 9.07.  Moneys Held by Paying Agent.
               ----------------------------

                  In connection with the satisfaction and discharge of this
Indenture, all moneys then held by any Paying Agent under the provisions of this
Indenture shall, upon written demand of the Company, be paid to the Trustee, or
if sufficient moneys have been deposited pursuant to Section 9.01 hereof, to the
Company upon an Company Request (or, if such moneys had been deposited by any
Guarantors, to such Guarantors), and thereupon such Paying Agent shall be
released from all further liability with respect to such moneys.

Section 9.08.  Moneys Held by Trustee.
               -----------------------

                  Any moneys deposited with the Trustee or any Paying Agent or
then held by the Company or any Guarantors in trust for the payment of the
principal of, or premium, if any, or interest on any Note that are not applied
but remain unclaimed by the Holder of such Note for two years after the date
upon which the principal of, or premium, if any, or interest on such Note shall
have respectively become due and payable shall be repaid to the Company (or, if
appropriate, the Guarantors) upon an Company Request, or if such moneys are then
held by the Company or the Guarantors in trust, such moneys shall be released
from such trust; and the Holder of such Note entitled to receive such payment
shall thereafter, as an unsecured general creditor, look only to the Company and
the Guarantors for the payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money shall thereupon cease; PROVIDED,
HOWEVER, that the Trustee or any such Paying Agent, before being required to
make any such repayment, may, at the expense of the Company and the Guarantors,
if any, either mail to each Noteholder affected, at the address shown in the
register of the Notes maintained by the Registrar pursuant to Section 2.03
hereof, or cause to be published once a week for two successive weeks, in a
newspaper published in the English language, customarily published each Business
Day and of general circulation in the City of New York, New York, a notice that
such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such mailing or publication, any
unclaimed balance of such moneys then



   92


                                      -85-



remaining will be repaid to the Company. After payment to the Company or any
Guarantor or the release of any money held in trust by the Company or any
Guarantor, as the case may be, Noteholders entitled to the money must look only
to the Company and any Guarantors for payment as general creditors unless
applicable abandoned property law designates another Person.


                                   ARTICLE 10

                               GUARANTEE OF NOTES


Section 10.01.  Guarantee.
                ----------

                  Subject to the provisions of this Article 10, each Guarantor,
by execution of a Guarantee, will jointly and severally unconditionally
guarantee to each Holder and to the Trustee, on behalf of the Holders, (i) the
due and punctual payment of the principal of, and premium, if any, and interest
on each Note, when and as the same shall become due and payable, whether at
maturity, by acceleration or otherwise, the due and punctual payment of interest
(including Additional Interest) on the overdue principal of, and premium, if
any, and interest on the Notes, to the extent lawful, and the due and punctual
performance of all other Obligations of the Company to the Holders or the
Trustee (including without limitation amounts due the Trustee under Section
7.07) all in accordance with the terms of such Note and this Indenture, and (ii)
in the case of any extension of time of payment or renewal of any Notes or any
of such other Obligations, that the same will be promptly paid in full when due
or performed in accordance with the terms of the extension or renewal, at stated
maturity, by acceleration or otherwise. Each Guarantor, by execution of a
Guarantee, will agree that its obligations hereunder shall be absolute and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of any such Note or this Indenture, any failure
to enforce the provisions of any such Note or this Indenture, any waiver,
modification or indulgence granted to the Company with respect thereto by the
Holder of such Note or the Trustee, or any other circumstances which may
otherwise constitute a legal or equitable discharge of a surety or such
Guarantor.

                  Each Guarantor, by execution of a Guarantee, will waive
diligence, presentment, demand for payment, filing of claims with a court in the
event of merger or bankruptcy of the Company, any right to require a proceeding
first against the Company, protest



   93


                                      -86-



or notice with respect to any such Note or the Indebtedness evidenced thereby
and all demands whatsoever, and will covenant that the Guarantee will not be
discharged as to any such Note except by payment in full of the principal
thereof, premium if any, and interest thereon and as provided in Section 9.01
hereof. Each Guarantor, by execution of a Guarantee, will further agree that, as
between such Guarantor, on the one hand, and the Holders and the Trustee, on the
other hand, (i) the maturity of the Obligations guaranteed hereby may be
accelerated as provided in Article 6 hereof for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Obligations guaranteed hereby, and (ii) in the
event of any declaration of acceleration of such Obligations as provided in
Article 6 hereof, such Obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of this
Guarantee. In addition, without limiting the foregoing provisions, upon the
effectiveness of an acceleration under Article 6 hereof, the Trustee shall
promptly make a demand for payment on the Notes under the Guarantee provided for
in this Article 10 and not discharged. Failure to make such a demand shall not
affect the validity or enforceability of the Guarantee upon any Guarantor.

                  A Guarantee shall not be valid or become obligatory for any
purpose with respect to a Note until the certificate of authentication on such
Note shall have been signed by or on behalf of the Trustee.

                  A Guarantee shall remain in full force and effect and continue
to be effective should any petition be filed by or against the Company for
liquidation or reorganization, should the Company become insolvent or make an
assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Securities
are, pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by any obligee on the Securities, whether as a
"voidable preference," "fraudulent transfer" or otherwise, all as though such
payment or performance had not been made. In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities shall,
to the fullest extent permitted by law, be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned.




   94


                                      -87-



                  No stockholder, officer, director, employer or incorporator,
past, present or future, of any Guarantor, as such, shall have any personal
liability under this Guarantee by reason of his, her or its status as such
stockholder, officer, director, employer or incorporator.

                  A Guarantor, by execution of a Guarantee, will have the right
to seek contribution from any non-paying Guarantor so long as the exercise of
such right does not impair the rights of the Holders under such Guarantee.

Section 10.02.  Execution and Delivery of Guarantees.
                -------------------------------------

                  A Guarantee shall be executed on behalf of a Guarantor by the
manual or facsimile signature of an Officer of such Guarantor.

                  If an Officer of a Guarantor whose signature is on the
Guarantee no longer holds that office, such Guarantee shall be valid
nevertheless.

Section 10.03.  Limitation of Guarantee.
                ------------------------

                  The obligations of each Guarantor are limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from or
payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Guarantee or pursuant to its
contribution obligations under this Indenture, result in the obligations of such
Guarantor under the Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal or state law. Each Guarantor that makes a
payment or distribution under a Guarantee shall be entitled to a contribution
from each other Guarantor in a pro rata amount based on the Adjusted Net Assets
of each Guarantor.

Section 10.04.  Additional Guarantors.
                ----------------------

                  Any person may become a Guarantor by executing and delivering
to the Trustee (a) a supplemental indenture in form and substance satisfactory
to the Trustee, which subjects such person to the provisions of this Indenture
as a Guarantor, and (b) an Opinion of Counsel to the effect that such
supplemental indenture has been duly authorized and executed by such person and
constitutes the legal, valid, binding and enforceable obligation of such person
(subject to such customary exceptions concerning fraudulent conveyance laws,
creditors' rights and



   95


                                      -88-



equitable principles as may be acceptable to the Trustee in its discretion).

Section 10.05.  Release of Guarantor.
                ---------------------

                  A Guarantor shall be released from all of its obligations
under its Guarantee if:

                    (i) the Guarantor has sold all or substantially all of its
         assets or the Company and its Restricted Subsidiaries have sold all of
         the Capital Stock of the Guarantor owned by them, in each case in a
         transaction in compliance with Sections 4.10 and 5.01 hereof; or

                   (ii) the Guarantor merges with or into or consolidates with,
         or transfers all or substantially all of its assets to, the Company or
         another Guarantor in a transaction in compliance with Section 5.01
         hereof;

and in each such case, such Guarantor has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with.

loan, security or debt agreement of the Company or any Subsidiary thereof. No
such indenture, loan, security or debt agreement may be used to interpret this
Indenture.

Section 11.10.  No Recourse Against Others.

present or future, of the Company or of any successor corporation or against the
property or assets of any such stockholder, officer, employee, partner,
affiliate, beneficiary or director, either directly or through the Company or
any Guarantor, or any successor corporation thereof, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that this Indenture and the
Notes are solely obligations of the Company and any Guarantors, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, any
stockholder, officer, employee, partner, affiliate, beneficiary or director of
the Company or any Guarantor, or any successor corporation thereof, because of
the creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or the Notes or
implied therefrom, and that any and all such personal liability of, and any and
all claims against every stockholder, officer, employee, partner, affiliate,
beneficiary and director, are hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issuance of the Notes. It is understood that this limitation on recourse is

                                GLASSTECH SUB CO.

                          12 3/4% SENIOR NOTE DUE 2004


         1. INTEREST. Glasstech Sub Co., a Delaware corporation (the "Company"),
promises to pay, until the principal hereof is paid or made available for
payment, interest on the principal amount set forth on the face hereof at a rate
of 12 3/4% per annum. Interest hereon will accrue from and including the most
recent date to which interest has been paid or, if no interest has been paid,
from and including July 2, 1997 to but excluding the date on which interest is
paid. Interest shall be payable in arrears on each January 1 and July 1
commencing January 1, 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 and on overdue interest (to the full extent permitted by law) at a
rate of 12 3/4% per annum.

         2. METHOD OF PAYMENT. The Company will pay interest hereon (except
defaulted interest) to the Persons who are registered Holders at the close of
business on December 15 or June 15 next preceding the interest payment date
(whether or not a Business Day). Holders must surrender Notes to a Paying Agent
to collect principal payments. The Company will pay principal and interest in
money of the United States of America that at the time of payment is legal
tender for payment of public and private debts. Interest may be paid by check
mailed to the Holder entitled thereto at the address indicated on the register
maintained by the Registrar for the Notes.

         3. PAYING AGENT AND REGISTRAR. Initially, United States Trust Company
of New York (the "Trustee") will act as a Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice. Neither the
Company nor any of its Affiliates may act as Paying Agent or Registrar.

         4. INDENTURE. The Company issued the Notes under an Indenture dated as
of July 2, 1997 (the "Indenture") by and between the Company and the Trustee.
This is one of an issue of Notes of the Company issued, or to be issued, under
the Indenture. The terms of the Notes 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. Code Sections 77aaa-77bbbb), as amended from time to time. The Notes 
are subject to all such terms, and Holders are referred to the Indenture and 
such Act for a statement of them. Capitalized and certain other terms used 
herein and not otherwise defined have the meanings set forth in the Indenture.
The Notes are obligations of the Company limited in aggregate principal amount 
to $70.0 million.

         5. OPTIONAL REDEMPTION. The Company, at its option, may redeem the
Notes, in whole or in part, at any time on or after July 1, 2002 upon not less
than 30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount), set forth below, together, in each case, with
accrued and unpaid interest to the Redemption Date, if redeemed during the
twelve month period beginning on July 1 of each year listed below:



     Year                                     Redemption Price
     ----                                     ----------------

                                                 
2002.........................................       103.188%
2003.........................................       100.000%


                  Notwithstanding the foregoing, the Company may redeem in the
aggregate up to 25% of the original principal amount of Notes at any time and
from time to time on or prior to July 1, 2000 at a redemption price equal to
112.75% of the aggregate principal amount thereof, plus accrued and unpaid
interest thereon to the Redemption Date with the Net Proceeds of one or more
Qualified Equity Offerings of the Company or Holding to the extent such proceeds
were contributed to the Company as common equity; PROVIDED, that at least $52.5
million of the principal amount of Notes originally issued remains outstanding
immediately after the occurrence of any such redemption and that any such
redemption occurs within 90 days following the closing of any such Qualified
Equity Offering.

         6. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the Redemption Date to each Holder of
Notes to be redeemed at his registered address. On and after the Redemption
Date, unless the Company defaults in making the redemption payment, interest
ceases to accrue on Notes or portions thereof called for redemption.

         7. OFFERS TO PURCHASE. The Indenture provides that upon the occurrence
of a Change of Control or an Asset Sale and subject to further limitations
contained therein, the Company shall make an offer to purchase outstanding Notes
in accordance with the procedures set forth in the Indenture.

         8. REGISTRATION RIGHTS. Pursuant to a Registration Rights Agreement by
and between the Company and CIBC Wood Gundy Securities Corp., as Initial
Purchaser of the Notes, the Company will be obligated to consummate an exchange
offer pursuant to which the Holder of this Note shall have the right to exchange
this Note for notes of a separate series issued under the Indenture (or a trust
indenture substantially identical to the Indenture in accordance with the terms
of the Registration Rights Agreement) which have been registered under the
Securities Act, in like principal amount and having substantially identical
terms


                                       A-4

   106



as the Notes. The Holders shall be entitled to receive certain additional
interest payments in the event such exchange offer is not consummated and upon
certain other conditions, all pursuant to and in accordance with the terms of
the Registration Rights Agreement.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. A
Holder may transfer or exchange Notes in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay to it any taxes and fees required
by law or permitted by the Indenture. The Registrar need not register the
transfer of or exchange any Notes or portion of a Note selected for redemption,
or register the transfer of or exchange any Notes for a period of 15 days before
a mailing of notice of redemption.

         10. PERSONS DEEMED OWNERS. The registered Holder of this Note may be
treated as the owner of this Note for all purposes.

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

         12. AMENDMENT, SUPPLEMENT, WAIVER, ETC. Subject to certain exceptions,
the Indenture or the Notes may be modified, amended or supplemented by the
Company, the Guarantors, if any, and the Trustee with the consent of the Holders
of at least a majority in principal amount of the Notes then outstanding and any
existing default or compliance with any provision may be waived in a particular
instance with the consent of the Holders of a majority in principal amount of
the Notes then outstanding. Without the consent of Holders, the Company, the
Guarantors, if any, and the Trustee may amend the Indenture or the Notes or
supplement the Indenture for certain specified purposes, including providing for
uncertificated Notes in addition to certificated Notes, and curing any
ambiguity, defect or inconsistency, or making any other change that does not
materially and adversely affect the rights of any Holder.

         13. RESTRICTIVE COVENANTS. The Indenture imposes certain limitations on
the ability of the Company and its Restricted Subsidiaries to, among other
things, incur additional Indebtedness, make payments in respect of their Capital
Stock or certain Indebtedness, make certain Investments, create or incur liens,
enter into transactions with Affiliates, enter into agreements restricting the
ability of Restricted Subsidiaries to pay dividends and make distributions,
issue Preferred Stock of


                                       A-5

   107



any Restricted Subsidiaries of the Company, enter into sale and leaseback
transactions and on the ability of the Company to merge or consolidate with any
other Person or transfer all or substantially all of the Company's or any
Guarantor's assets. Such limitations are subject to a number of important
qualifications and exceptions. Pursuant to Section 4.04 of the Indenture, the
Company must annually report to the Trustee on compliance with such limitations.

         14. SUCCESSOR CORPORATION. When a successor corporation assumes all the
obligations of its predecessor under the Notes and the Indenture and the
transaction complies with the terms of Article 5 of the Indenture, the
predecessor corporation will, except as provided in Article 5, be released from
those obligations.

         15. DEFAULTS AND REMEDIES. Events of Default are set forth in the
Indenture. Subject to certain limitations in the Indenture, if an Event of
Default (other than an Event of Default specified in Section 6.01(6) or (7) of
the Indenture with respect to the Company) occurs and is continuing, the Trustee
or the Holders of not less than 25% in aggregate principal amount of the
outstanding Notes may, by written notice to the Trustee and the Company, and the
Trustee upon the request of the Holders of not less than 25% in aggregate
principal amount of the outstanding Notes shall, declare all principal of and
accrued interest on all Notes to be immediately due and payable; PROVIDED,
HOWEVER, that after such acceleration but before judgment or decree based on
such acceleration is obtained by the Trustee, the Holders of a majority in
aggregate principal amount of the outstanding Notes may rescind and annul such
acceleration and its consequences if all existing Events of Default, other than
the nonpayment of principal, premium or interest that has become due solely
because of the acceleration, have been cured or waived and if the rescission
would not conflict with any judgment or decree. If an Event of Default specified
in Section 6.01(6) or (7) of the Indenture occurs with respect to the Company,
the principal amount of and interest on, all Notes shall IPSO FACTO become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes
except as provided in the Indenture. The Trustee may require indemnity
satisfactory to it before it enforces the Indenture or the Notes. Subject to
certain limitations, Holders of a majority in principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders notice of any continuing default (except a
default in payment of principal or interest) if it determines that withholding
notice is in their interests.

         16. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
any other capacity, may make loans to, accept


                                       A-6

   108



deposits from, and perform services for the Company or its Affiliates, and may
otherwise deal with the Company or its Affiliates, as if it were not Trustee.

         17. NO RECOURSE AGAINST OTHERS. No director, officer, employee
incorporator or stockholder, of the Company or any Guarantor shall have any
liability for any obligations of the Company or the Guarantors, if any, under
the Notes, the Indenture or the Guarantees, if any, or for a claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder of
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Notes.

         18. DISCHARGE. The Company's obligations pursuant to the Indenture will
be discharged, except for obligations pursuant to certain sections thereof,
subject to the terms of the Indenture, upon the payment of all the Notes or upon
the irrevocable deposit with the Trustee of United States dollars or U.S.
Government Obligations sufficient to pay when due principal of and interest on
the Notes to maturity or redemption, as the case may be.

         19. AUTHENTICATION. This Note shall not be valid until the Trustee
signs the certificate of authentication on the other side of this Note.

         20. GOVERNING LAW. THE INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO
THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE OR THE NOTES.

Attention:

                  Re:      Glasstech Sub Co. (the "Company")
                           12 3/4% Senior Notes due 2004 (the "Notes")


Dear Sirs:

                  In connection with our proposed purchase of Notes of the
Company, we confirm that:

         1. We understand that any subsequent transfer of the Notes is subject
to certain restrictions and conditions set forth in the Indenture dated as of
July 2, 1997 relating to the Notes and we agree to be bound by, and not to
resell, pledge or otherwise transfer the Notes except in compliance with, such
restrictions and conditions and the Securities Act of 1933, as amended (the
"Securities Act").

         2. We understand that the Notes have not been registered under the
Securities Act, and that the Notes may not be offered, sold, pledged or
otherwise transferred except as permitted in the following sentence. We agree,
on our own behalf and on behalf of any accounts for which we are acting as
hereinafter stated, that if we should sell any Notes, we will do so only (i) to
the Company or any subsidiary thereof, (ii) pursuant to an effective
registration statement under the Securities Act, (iii) in accordance with Rule
144A under the Securities Act to a "qualified institutional buyer" (as defined
in Rule 144A), (iv) to an institutional "accredited investor" (as defined below)
that, prior to such transfer, furnishes (or has furnished on its behalf by a
U.S. broker-dealer) to you a signed letter containing certain



                                       E-1

   120






representations and agreements relating to the restrictions on transfer of the
Notes, (v) outside the United States to persons other than U.S. persons in
offshore transactions meeting the requirements of Rule 904 of Regulation S under
the Securities Act, or (vi) pursuant to any other exemption from registration
under the Securities Act (if available), and we further agree to provide to any
person purchasing any of the Notes from us a notice advising such purchaser that
resales of the Notes are restricted as stated herein.

         3. We are not acquiring the Notes for or on behalf of, and will not
transfer the Notes to, any pension or welfare plan (as defined in Section 3 of
the Employee Retirement Income Security Act of 1974, as amended), except as
permitted in the section entitled "Notice to Investors" of the Memorandum.

         4. We understand that, on any proposed resale of any Notes, we will be
required to furnish to you and the Company such certifications, legal opinions
and other information as you and the Company may reasonably require to confirm
that the proposed sale complies with the foregoing restrictions. We further
understand that the Notes purchased by us will bear a legend to the foregoing
effect.

         5. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and 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 Notes, and we and
any accounts for which we are acting each are able to bear the economic risk of
our or their investment, as the case may be.

         6. We are acquiring the Notes purchased by us for our account or for
one or more accounts (each of which is an institutional "accredited investor")
as to each of which we exercise sole investment discretion.

        (2) either (a) at the time the buy offer was originated, the transferee

    designated off-shore securities market and neither we nor any person acting

    in the United States;

    contravention of the requirements of Rule 903(b) or Rule 904(b) of
