"Company"), for value received, hereby promises to pay to
________________________, or registered assigns, the principal sum of

currency of the United States of America as at the time of payment is legal
tender for the payment of public and private debts, and to pay to the registered
holder hereof, as hereinafter provided, interest on said principal sum at the
rate per annum specified in the title of this Note, in like coin or currency,
semi-annually in arrears on June 15 and December 15 in each year, commencing on
June 15, 1999. Interest shall accrue from the most recent date to which interest
has been paid or duly provided for or, if no interest has been paid or duly
provided for, from December 21, 1998; provided, however, that, in the case of
authentication between the record date for any interest payment date and such

payable on any June 15 or December 15 will, subject to certain exceptions
provided in the Indenture, be paid to the Person in whose name this Note is
registered at the close of business on the May 30 immediately preceding such
June 15 or the November 30 immediately preceding such December 15. Interest
shall be computed on the basis of a 360-day year of twelve 30-day months.

          Principal of, and premium, if any, Change of Control Purchase Price,
Asset Sale Purchase Price and interest on, this Note are payable at the office
or agency of the Company maintained for such purpose within the City and State
of New York, except that, at the option of the Company, payment of interest
hereon may be made by check mailed by first-class mail to the address of the
Person entitled thereto at such address as shall appear on the registry books of
the Company; provided, however, that, if this Note is a Global Note or a
Certificated Note and the holder of this Note has given wire transfer
instructions (which instructions must be received by the Company at least 5
Business Days prior to the relevant date of payment) to the Company, all
payments with respect to this Note will be required to be made by wire transfer
of immediately available funds to the account specified by the holder of this
Note; provided, further, that, in the case of all payments other than interest,
the holder of this Note must first surrender this Note as a condition to the
holder's right to receive payment.

          As provided in the Indenture, this Note shall be deemed to be a
contract made under the laws of the State of New York, and for all purposes
shall be governed by and construed in accordance with the laws of such State.

          This Note shall not be valid or become obligatory for any purpose
until the certificate of authentication hereon shall have been signed by the
Trustee under the Indenture.

          This Note is one of a duly authorized issue of Notes of the Company
known as its 12% [Series A] [Series B] First Mortgage Notes due 2006 (herein
referred to as the "Notes"), limited to an 

                                      -2-


aggregate principal amount of one hundred fifty million dollars ($150,000,000),
all issued or to be issued under and pursuant to an indenture, dated as of
December 21, 1998 (herein referred to as the "Indenture"), among the Company,
the Subsidiaries (as defined in the Indenture) of the Company and U.S. Trust
Company, National Association, as trustee (herein referred to as the "Trustee"),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a description of the respective rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company, the
Subsidiaries of the Company and the holders of the Notes. All terms used in this
Note which are defined in the Indenture shall have the meanings assigned to them
in the Indenture.

          In case an Event of Default shall have occurred and be continuing, the
principal amount of this Note plus any accrued and unpaid interest to the date
of acceleration may be declared, and upon such declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions provided
in the Indenture. The Indenture provides that the holders of a majority of the
aggregate principal amount of the Notes at the time outstanding or outstanding
on the record date, if any, fixed therefor in accordance with the provisions of
the Indenture may on behalf of the holders of all of the Notes waive any past
default under the Indenture and its consequences (including any acceleration,
other than an automatic acceleration resulting from certain bankruptcy,
insolvency, receivership or reorganization), except a default in the payment of
the principal of, premium, if any, Change of Control Purchase Price, Asset Sale
Purchase Price or interest on, any of the Notes (other than solely as a result
of an acceleration) or a default under any covenant or provision in the
Indenture which under Article Ten of the Indenture cannot be modified or amended
without the consent of the holder of each outstanding Note. In the case of any
such waiver, the Company, the Trustee and the holders of the Notes shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

          Payment of the Notes is fully and unconditionally guaranteed, jointly
and severally, by Northwest Aluminum Specialties, Inc., Northwest Aluminum
Company, Northwest Aluminum Technologies, LLC, Goldendale Holding Company and
Goldendale Aluminum Company and will be guaranteed on a senior basis by all
future Subsidiaries of the Company. Under certain circumstances set forth in the
Indenture, each of the Subsidiaries of the Company may be released from its
respective obligations under and in respect of the Indenture and the Notes.

          To secure payment of the Notes, each of the Company and its
Subsidiaries has granted to the Trustee, as collateral agent for and on behalf
of the holders of the Notes and pursuant to the Security Agreements, (i) a first
priority security interest in substantially all of the Company's and its
existing Subsidiaries' real property, plant and equipment (other than the
Excluded Property), and certain other assets of the Company and its existing
Subsidiaries, excluding, however, among other things, the Tolling Agreements,
inventory, accounts receivable and other rights to payment and related
intangibles and proceeds thereof and (ii) a pledge of all of the issued and
outstanding Capital Stock of each direct or indirect Subsidiary of the Company
and all income, benefits and rights derived therefrom and all proceeds thereof.
Under certain circumstances set forth in the Indenture, the Capital Stock issued
by any Subsidiary of the Company may be released from such security interest. In
addition, upon the designation of a Subsidiary as an Unrestricted Subsidiary by
the Board of Directors in accordance with the provisions of the Indenture, the
Collateral Agent shall release any Collateral of such Unrestricted Subsidiary in
the manner contemplated by the Security Agreements; provided, however, that any
such Collateral shall only be released from the Security Agreements to the
extent such Collateral is also released from the Hydro Agreement and the Credit
Agreement.


                                      -3-


          The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority of the
aggregate principal amount of the Notes then outstanding or outstanding on the
record date, if any, fixed therefor in accordance with the provisions of the
Indenture, evidenced as in the Indenture provided, to execute supplemental
indentures adding any provisions to or changing in any manner or eliminating any
of the provisions of the Indenture or of any supplemental indenture or modifying
in any manner the rights of the holders of the Notes; provided, however, that,
as provided in Section 10.02 of the Indenture, without the consent of each
holder of an outstanding Note affected, no such supplemental indenture shall,
inter alia, (i) extend the stated maturity of any Note, reduce the rate at which
interest accrues on any Note, extend the time or alter the manner of payment of
interest on any Note, reduce the principal amount of any Note, alter the timing
of or reduce any premium payable upon the redemption of any Note, change the
currency in which any payments are made on or with respect to any Note, change
the ranking or seniority of any Note or reduce the amount payable on any Note in
the event of acceleration or the amount of any Note payable in bankruptcy, or
(ii) reduce the aforesaid percentage of aggregate principal amount of Notes the
consent of the holders of which is required for any such supplemental indenture.
In addition, without the consent of the holders of not less than 66 2/3% in
aggregate principal amount of the outstanding Notes, the Collateral Agent and
the Company cannot (i) amend the Security Agreements or (ii) release any of the
Collateral from a Lien or the Security Agreements (except in accordance with the
provisions thereof).

          Any such consent or waiver by the registered holder of this Note
(unless effectively revoked as provided in the Indenture) shall be conclusive
and binding upon such holder and upon all future holders of this Note and of any
Note issued in exchange or substitution herefor, irrespective of whether or not
any notation of such consent or waiver is made upon this Note or such other
Note.

          No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, and premium, if any, Change
of Control Purchase Price, Asset Sale Purchase Price and interest on, this Note
at the place, at the respective times, at the rate and in the currency herein
prescribed.

          The Notes are issuable as fully registered Notes without coupons in
denominations of $1,000 and any integral multiple of $1,000. At the office or
agency to be maintained by the Company referred to above, and in the manner and
subject to the limitations provided in the Indenture, Notes may be exchanged for
a like aggregate principal amount of Notes in other authorized denominations,
without payment of any charge other than a sum sufficient to reimburse the
Company for any tax or other governmental charge incident thereto.

          The Company may not redeem the Notes before December 15, 2002. On or
after December 15, 2002, the Notes will be redeemable on at least 15 and not
more than 60 days' notice, at the option of the Company, in whole at any time or
in part from time to time, at the following redemption prices (expressed as a
percentage of principal amount), together with accrued and unpaid interest to
the date fixed for redemption, if redeemed during the 12-month period beginning
December 15 of the years indicated below:

                                      -4-


                                          REDEMPTION
           YEAR                              PRICE
           2002 . . . . . . . . . . . . . . 108.000%
           2003 . . . . . . . . . . . . . . 105.333%
           2004 . . . . . . . . . . . . . . 102.667%
           2005 and thereafter. . . . . . . 100.000%

          In the case of a partial redemption as provided above, the Trustee
shall select the Notes or portions thereof for redemption in such manner as it,
in its sole discretion, deems appropriate and fair. The Notes may be redeemed in
part in multiples of $1,000 only. The Notes will not have the benefit of any
sinking fund.

          Subject to the terms and conditions of the Indenture, if any Change of
Control occurs on or prior to maturity, the Company shall offer to purchase from
each holder all or any part (equal to $1,000 or an integral multiple thereof) of
the holder's Notes for which a Change of Control Purchase Notice shall have been
delivered as provided in the Indenture and not withdrawn, on the date that is 30
Business Days after the occurrence of such Change of Control (the "Change of
Control Purchase Date"), for a Change of Control Purchase Price equal to 101% of
the principal amount thereof plus accrued and unpaid interest to the Change of
Control Purchase Date, which Change of Control Purchase Price shall be paid in
cash.

          Holders have the right to withdraw any Change of Control Purchase
Notice by delivering to the Trustee a written notice of withdrawal in accordance
with the provisions of the Indenture.

          If cash sufficient to pay the Change of Control Purchase Price of all
Notes or portions thereof to be purchased on the Change of Control Purchase Date
is deposited with the Trustee as of the Change of Control Purchase Date,
interest shall cease to accrue (whether or not this Note is delivered to the
Trustee or any other office or agency maintained for such purpose) on such Notes
(or portions thereof) on and after the Change of Control Purchase Date, and the
holders thereof shall have no other rights as such (other than the right to
receive the Change of Control Purchase Price, upon surrender of such Notes).

          Subject to the terms and conditions of the Indenture, the Company
shall apply the Net Cash Proceeds of Asset Sales, under certain circumstances
described in the Indenture, to (x) the prepayment of Specified Pari Passu
Indebtedness, unless the holders thereof elect not to receive such prepayment
(provided that, in the event any such Indebtedness was Incurred under a
revolving credit arrangement, such prepayment shall be accompanied by a
permanent reduction of the commitment in respect thereof), and (y) an offer to
purchase (an "Asset Sale Offer") the then outstanding Notes, on any Business Day
occurring no later than 305 days after the receipt by the Company (or any of its
Subsidiaries, if applicable) of such Net Cash Proceeds (subject to deferral
under certain circumstances), at a price equal to 100% of the principal amount
thereof together with accrued and unpaid interest, if any, to the Asset Sale
Purchase Date pursuant to the provisions set forth below and in the Indenture.
Such Asset Sale Offer with respect to the Notes shall be in an aggregate
principal amount (the "Asset Sale Offer Amount") equal to the Net Cash Proceeds
(rounded down to the nearest $1,000) from the Asset Sales to which the Asset
Sale Offer relates multiplied by a fraction, the numerator of which is the
principal amount of the Notes outstanding (determined as of the close of
business on the day immediately preceding the date notice of such Asset 

                                      -5-



Sale Offer is mailed) and the denominator of which is the principal amount of
the Notes outstanding plus the aggregate principal amount of Specified Pari
Passu Indebtedness outstanding (determined as of the close of business on the
day immediately preceding the date notice of such Asset Sale Offer is mailed).
If (x) no Specified Pari Passu Indebtedness is outstanding or (y) the holders of
such Indebtedness entitled to receive payment elect not to receive the payments
provided for in the previous sentence, or (z) the application of such Net Cash
Proceeds results in the complete prepayment of such Indebtedness, then in each
case any remaining portion of such Net Cash Proceeds will be required to be
applied to an Asset Sale Offer to purchase the Notes.

          Upon surrender of this Note, the transfer of this Note is registrable
by the registered holder hereof in person or by his attorney duly authorized in
writing on the registry books of the Company at the office or agency to be
maintained by the Company referred to above, subject to the terms of the
Indenture but without payment of any charge other than a sum sufficient to
reimburse the Company for any tax or other governmental charge incident thereto.
Upon any such registration of transfer, a new Note or Notes of authorized
denomination or denominations, for the same aggregate principal amount, will be
issued to the transferee in exchange herefor.

          Prior to due presentation for registration of transfer, the Company,
the Trustee, any paying agent and any Note registrar may deem and treat the
Person in whose name this Note shall be registered upon the registry books of
the Company as the absolute owner of this Note (whether or not this Note shall
be overdue and notwithstanding any notation of ownership or other writing
hereon), for the purpose of receiving payment of or on account of the principal
hereof, and premium, if any, Change of Control Purchase Price, Asset Sale
Purchase Price and interest due hereon, and for all other purposes, and neither
the Company nor the Trustee nor any paying agent nor any Note registrar shall be
affected by any notice to the contrary. All such payments shall be valid and
effectual to satisfy and discharge the liability on this Note to the extent of
the sum or sums so paid.

          No recourse shall be had for the payment of the principal of, or
premium, if any, Change of Control Purchase Price, Asset Sale Purchase Price or
interest on, this Note, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Indenture or any indenture supplemental
thereto, against any incorporator, stockholder (other than the Company or any of
its Subsidiaries), officer or director, as such, past, present or future, of the
Company or any of its Subsidiaries or of any successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.

          IN WITNESS WHEREOF, GOLDEN NORTHWEST ALUMINUM, INC. has caused this
instrument to be duly executed.

                        ---------------------------------------------------
Notes.
- -----

          The Notes shall be designated as the Company's 12% First Mortgage
Notes due 2006. Notes for an aggregate principal amount of one hundred fifty
million dollars ($150,000,000), upon the execution of this Indenture, or from
time to time thereafter, may be executed by the Company and delivered to the
Trustee for authentication, and the Trustee shall thereupon authenticate and
deliver said Notes to or upon the written order of the Company, signed by its
Chairman of the Board, President, Chief Financial Officer or a Vice President,
without any further corporate action by the Company. The Trustee shall
authenticate Exchange Notes from time to time for issue only in exchange for a
like principal amount of Initial Notes, in each case upon a written order of the
Company, signed by its Chairman of the Board, President, Chief Financial Officer
or a Vice President, without any further corporate action by the Company. The
written order of the Company shall specify the amount of Notes to be
authenticated and the date on which the Notes are to be authenticated, whether
the Notes are to be Initial Notes or Exchange Notes and whether the Notes are to
be issued as Certificated Notes, a Global Note or a Regulation S Temporary
Global Note, and such other information as the Trustee may reasonably request.

          The aggregate principal amount of Notes authorized by this Indenture
is limited to one hundred fifty million dollars ($150,000,000) and, except as
provided in this Section 2.01 and in Section 2.07, the Company shall not execute
and the Trustee shall not authenticate or deliver Notes in excess of 

                                      -29-



such aggregate principal amount.

          Nothing contained in this Section 2.01 or elsewhere in this Indenture,
or in the Notes, is intended to or shall limit execution by the Company or
authentication or delivery by the Trustee of Notes under the circumstances
contemplated by Sections 2.05, 2.06, 2.07, 3.03, 3.05, 4.14 and 10.04.

          Section 2.02. Form of Notes and Trustee's Certificate.
                        ---------------------------------------

          The definitive Notes and the Trustee's certificate of authentication
to be borne by the Notes shall be substantially in the form set forth in the
Recitals of this Indenture, which are part of this Indenture, and may have such
letters, numbers or other marks of identification or designation and such
legends or endorsements printed, lithographed or engraved thereon as the
officers executing the same may deem appropriate and as are not inconsistent
with the provisions of this Indenture, or as may be required to comply with any
law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any stock exchange on which the Notes may be listed, or to conform
to usage.

          Notes offered and sold in reliance on Rule 144A shall be issued
initially in the form of a single, permanent global Note in fully registered
form, without interest coupons, substantially in the form set forth in the
recitals to this Indenture (the "Global Note"), deposited with the Trustee, as
custodian for the Depository, and registered in the name of Cede & Co., or such
other nominee as the Depository may designate, duly executed by the Company and
authenticated by the Trustee as hereinafter provided and shall bear the legends
set forth in Section 2.09 hereof. The aggregate principal amount of the Global
Note may from time to time be increased or decreased by adjustments made on the
records of the Trustee, as custodian for the Depository, as hereinafter
provided.

          Notes offered and sold in reliance on Regulation S shall be issued
initially in the form of the Regulation S Temporary Global Note in fully
registered form, which shall be deposited on behalf of the purchasers of the
Notes represented thereby with the Trustee, as custodian for the Depository, and
registered in the name of the Depository or the nominee of the Depository, duly
executed by the Company and authenticated by the Trustee as hereinafter
provided. The 40-day distribution compliance period (as defined in Regulation S)
shall be terminated upon the receipt by the Trustee of (i) a written certificate
from the Depository as to the non-United States beneficial ownership of 100% of
the aggregate principal amount of the Regulation S Temporary Global Note (except
to the extent of any beneficial owners thereof who acquired an interest therein
pursuant to another exemption from registration under the Securities Act of
1933, all as contemplated by Section 2.05(e) hereof), and (ii) an Officers'
Certificate from the Company certifying as to the matters covered in clause (i)
above. Following the termination of the 40-day distribution compliance period,
beneficial interests in the Regulation S Temporary Global Note shall be
exchanged for Certificated Notes or beneficial interests in the Global Note
pursuant to the applicable procedures of the Depository. Until this Regulation S
Temporary Global Note is exchanged for interests in the Global Notes or for
Certificated Notes, the Holder hereof shall not be entitled to receive payments
of interest hereon; until so exchanged in full, this Regulation S Temporary
Global Note shall in all other respects be entitled to the same benefits as
other Notes under the Indenture. The aggregate principal amount of the
Regulation S Temporary Global Note may from time to time be increased or
decreased by adjustments made on the records of the Trustee, as custodian for
the Depository, as hereinafter provided.

          Notes offered and sold in reliance on any other exemption from
registration under the Securities Act of 1933 other than as described in the
preceding paragraph shall be issued, and Notes offered and sold in reliance on
Rule 144A may be issued, in the form of certificated Notes in fully registered
form, without interest coupons, in substantially the form set forth in the
recitals to this Indenture 

                                      -30-



(the "Certificated Notes"). Certificated Notes shall initially be registered in
the name of the Depository or a nominee of the Depository and be delivered to
the Trustee as custodian for the Depository, duly executed by the Company and
authenticated by the Trustee as hereinafter provided. Beneficial owners of
Certificated Notes, however, may request registration of such Certificated Notes
in their names or the names of their nominees.

          The Trustee assumes no liability for incorrect CUSIP numbers, and
incorrect CUSIP numbers shall have no effect on the validity of any notice given
under this Indenture.

          Section 2.03. Date of Notes and Denominations.
                        -------------------------------

          The Notes shall bear interest at the rate per annum of 12% from
December 21, 1998, payable semi-annually in arrears on June 15 and December 15,
commencing on June 15, 1999, shall mature on December 15, 2006 and shall be
issuable as registered Notes without coupons in denominations of $1,000 and any
integral multiple thereof. The Person in whose name any Note is registered at
the close of business on any record date (as hereinbelow defined) with respect
to any interest payment date shall be entitled to receive the interest payable
thereon on such interest payment date notwithstanding the cancellation of such
Note upon any registration of transfer or exchange thereof subsequent to such
record date and prior to such interest payment date, unless such Note shall have
been redeemed on a date fixed for redemption subsequent to such record date and
prior to such interest payment date, or unless an Event of Default shall have
occurred and be continuing as the result of a default in the payment of interest
due on such interest payment date on any Note, in which case such defaulted
interest shall be paid to the Person in whose name such Note (or any Note or
Notes issued upon registration of transfer or exchange thereof) is registered on
the record date for the payment of such defaulted interest. The principal of,
and premium, if any, Change of Control Purchase Price, Asset Sale Purchase Price
and interest on the Notes shall be payable to the registered holder thereof at
the office or agency to be maintained by the Company in accordance with the
provisions of Section 4.02, except that payment of interest may be made at the
option of the Company by check mailed by first-class mail to the address of the
Person entitled thereto as such address shall appear on the registry books of
the Company; provided, however, that, if a Note is a Global Note or a
Certificated Note and the holder of such Note has given wire transfer
instructions (which instructions must be received by the Company at least 5
Business Days prior to the relevant date of payment) to the Company, all
payments with respect to such Note will be required to be made by wire transfer
of immediately available funds to the account specified by the holder of such
Note; provided, further, that, in the case of payments other than interest, the
holder of a Note must first surrender such Note as a condition to the holder's
right to receive payment. The term "record date" as used in this Section 2.03
with respect to any interest payment date shall mean the close of business on
the May 30 immediately preceding such June 15 or the November 30 immediately
preceding such December 15, and such term, as used in this Section 2.03, with
respect to the payment of any defaulted interest shall mean the tenth day next
preceding the date fixed by the Company for the payment of defaulted interest,
whether or not a Business Day, but in no case shall such record date be less
than ten days after notice thereof shall have been mailed by or on behalf of the
Company to all registered holders of Notes at their addresses appearing upon the
registry books of the Company.

          Each Note shall be dated the date of its authentication. Interest
shall accrue on each Note from the most recent date to which interest has been
paid or duly provided for or, if no interest has been paid or duly provided for,
from the Issue Date; provided, however, that if there is no existing default in
the payment of interest and if a Note is authenticated between a record date for
any interest payment date and such interest payment date, interest on such Note
shall accrue from such interest payment date.

                                      -31-



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

          Until the Regulation S Temporary Global Note is exchanged for
interests in the Global Notes or for Certificated Notes, the Holder thereof
shall not be entitled to receive payments of interest thereon; until so
exchanged in full, the Regulation S Temporary Global Note shall in all other
respects be entitled to the same benefits as other Notes under the Indenture.

          Section 2.04. Execution of Notes.
                        ------------------

          The Notes shall be signed on behalf of the Company, manually or in
facsimile, by its Chairman of the Board, President, Chief Financial Officer or a
Vice President and attested, manually or in facsimile, by its Secretary or an
Assistant Secretary. Only such Notes as shall bear thereon a certificate of
authentication substantially in the form hereinbefore recited, signed manually
by the Trustee, shall be entitled to the benefits of this Indenture or be valid
or obligatory for any purpose. Such signature by the Trustee upon any Note
executed by the Company shall be conclusive evidence that the Note so
authenticated has been duly authenticated and delivered hereunder and that the
holder is entitled to the benefits of this Indenture.

          In case any officer of the Company whose signature appears on any of
the Notes, manually or in facsimile, shall cease to be such officer before such
Notes so signed shall have been authenticated and delivered by the Trustee, such
Notes nevertheless may be authenticated and delivered as though the Person whose
signature appears on such Notes had not ceased to be such officer of the
Company; and any Note may be signed and attested on behalf of the Company,
manually or in facsimile, by Persons as, at the actual date of the execution of
such Note, shall be the proper officers of the Company, although at the date of
the execution of this Indenture any such Person was not such officer.

          Section 2.05. Exchange and transfer of Notes.
                        ------------------------------

          (a) Subject to the other provisions of this Section 2.05:

          (1) Notes may be exchanged for a like aggregate principal amount of
Notes in other authorized denominations. Notes to be exchanged shall be
surrendered at the office or agency to be maintained by the Company in
accordance with the provisions of Section 4.02, and the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor the Note or
Notes which the noteholder making the exchange shall be entitled to receive.

          (2) The Company shall keep, at the office or agency to be maintained
by the Company in accordance with the provisions of Section 4.02, a register or
registers in which, subject to such reasonable regulations as it may prescribe,
the Company shall register Notes and shall register the transfer of Notes as in
this Article Two provided. Upon surrender by any noteholder for registration of
transfer of any Note at such office or agency, the Company shall execute and the
Trustee shall authenticate and deliver in the name of the transferee or
transferees a new Note or Notes for a like aggregate principal amount.

          (3) All Notes presented or surrendered for exchange, registration of
transfer, redemption, purchase or payment shall, if so required by the Company
or the Trustee or any Note registrar (if other than the Trustee), be accompanied
by a written instrument or instruments of transfer, in form satisfactory to the
Company and the Trustee or the Note registrar (if other than the Trustee), duly
executed 

                                      -32-



by the registered holder or by his attorney duly authorized in writing and, in
every case, each Note presented or surrendered for registration of transfer
shall be accompanied by the assignment form attached to the Notes, duly executed
by the registered holder or by his attorney duly authorized in writing.

          (4) No service charge shall be made for any exchange or registration
of transfer of Notes, but the Company may require payment of a sum sufficient to
cover any tax, assessment or other governmental charge that may be imposed in
relation thereto.

          (5) The Company shall not be required to issue, register the transfer
of or exchange any Notes for a period of fifteen days next preceding any date
for the selection of Notes to be redeemed. The Company shall not be required to
register the transfer of or exchange any Note called or being called for
redemption except, in the case of any Note to be redeemed in part, the portion
thereof not to be so redeemed. The Company shall not be required to register the
transfer of or exchange any Note in respect of which a Change of Control
Purchase Notice or an Asset Sale Purchase Notice has been given (unless such
notice has been withdrawn in accordance with Section 3.06 or 4.14) except, in
the case of any Note to be purchased in part, the portion thereof not to be so
purchased.

          (b) Transfers to Institutional Accredited Investors which are not
QIBs, Non-U.S. Persons and Certain QIBs. The following provisions shall apply
with respect to the registration of any proposed transfer of a Note to any
Institutional Accredited Investor which is not a QIB, to any Non-U.S. Person or
to any QIB electing to take delivery of Certificated Notes:

          (1) the Note registrar shall register on its books and records the
transfer of any Note constituting a Restricted Security if such transfer is (i)
pursuant to a registration statement which has been declared effective under the
Securities Act of 1933, (ii) for as long as the Notes are eligible for resale
pursuant to Rule 144A, by a Person who has checked the box provided for on the
form of Note stating, or has otherwise advised the Company and the Note
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 the form of Note stating, or has otherwise advised the Company
and the Note 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

Company's and the Trustee's right prior to any such offer, sale or transfer (A)
pursuant to clauses (iii), (iv) or (v) to require the delivery of an opinion of
counsel, certification and/or other information satisfactory to each of them and
(B) in each of the foregoing cases, to require that an assignment form in the

          (2) the Note registrar shall register on its books and records the

                                      -33-



          (3) if the proposed transferor is an Agent Member holding a beneficial
interest in the Global Note, upon receipt by the Note registrar of written
instructions given in accordance with the Depository's and the Note registrar's
procedures, the Note registrar shall reflect on its books and records the date

to the principal amount of the beneficial interest in the Global Note to be
transferred;

          (4) if the Notes to be transferred consist of Certificated Notes, the
transferor shall present or surrender such Certificated Notes to the Note

tenor and amount to the Notes proposed to be transferred hereunder.

          (c) Transfers to Certain QIBs. The following provisions shall apply
with respect to the registration of any proposed transfer of a Certificated Note
to a QIB electing to take an interest in the Global Note:

          (1) the Note registrar shall register on its books and records the
transfer of any Certificated Note constituting a Restricted Security if such
transfer is being made by a proposed transferor who has checked the box provided

Note 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 the form of Note stating, or has otherwise advised the Company
and the Note registrar in writing, that it is purchasing the Note for its own

amount of the Certificated Notes to be transferred, and the Trustee shall cancel
the Certificated Notes so transferred.

          (d) Transfers and Exchange of Global Securities. The transfer and
exchange of the Global Note, the Regulation S Temporary Global Note or
beneficial interests therein shall be effected through the Depository, in
accordance with this Indenture (including applicable restrictions on transfer

shall include restrictions on transfer comparable to those set forth herein to
the extent required by the Securities Act of 1933.

          (e) Transfers from the Regulation S Temporary Global Note. If, at any
time, an owner of a beneficial interest in the Regulation S Temporary Global
Note wishes to transfer its beneficial 

                                      -34-



interest in such Regulation S Temporary Global Note to a Person who is permitted
to take delivery thereof in the form of an interest in the Global Note or to a
Person who is taking delivery of such beneficial interest in the form of
Certificated Notes or, upon expiration of the 40-day distribution compliance
period and upon certification of beneficial ownership of the Notes represented
by the Regulation S Temporary Global Note by Non-U.S. Persons or U.S. Persons
who purchased such Notes in transactions that did not require registration under
the Securities Act of 1933, to exchange such beneficial interest for
Certificated Notes, such owner shall, subject to the applicable procedures of
the Depository, exchange or cause the exchange of such interest for an
equivalent beneficial interest in the Global Note or for Certificated Notes as
provided in this Section 2.05(e). Upon receipt by the Note registrar of (1)
instructions from the Depository, directing the Note registrar to credit or
cause to be credited a beneficial interest in the Global Note or to issue and
authenticate Certificated Notes in an amount equal to the beneficial interest in
the Regulation S Temporary Global Note to be transferred or exchanged, such
instructions to contain information regarding the participant account with the
Depository to be credited with such increase or the name and address of the
transferee thereof, as applicable, and (2) a certificate in the form of Exhibit
A-2 attached hereto given by the owner of such beneficial interest in the
Regulation S Temporary Global Note stating (A) if the transfer is pursuant to
Rule 144A, that the Person transferring such interest in the Regulation S
Temporary Global Note reasonably believes that the Person acquiring such
interest in the Global Note is a QIB and is obtaining such beneficial interest
in a transaction meeting the requirements of Rule 144A and any applicable blue
sky or securities laws of any state of the United States or (B) if the transfer
is pursuant to any other exemption from the registration requirements of the
Securities Act of 1933, that the transfer of such interest has been made in
compliance with the transfer restrictions applicable to the Regulation S
Temporary Global Note and pursuant to and in accordance with the requirements of
the exemption claimed, such statement, in the case of clause (B), to be
supported by an Opinion of Counsel from the transferee or the transferor in form
reasonably acceptable to the Company and to the Trustee, then the Note registrar
shall instruct the Depository to reduce or cause to be reduced the aggregate
principal amount of such Regulation S Temporary Global Note and (x) shall
instruct the Depository to increase or cause to be increased the aggregate
principal amount of the Global Note and instruct the Depository to credit or
cause to be credited to the account of the Person specified in such instructions
a beneficial interest in the Global Note or (y) shall issue and authenticate
Certificated Notes in an amount equal to the principal amount of the beneficial
interest in the Regulation S Temporary Global Note to be exchanged or
transferred, and the Note registrar shall instruct the Depository to debit or
cause to be debited from the account of the Person making such transfer the
beneficial interest in the Regulation S Temporary Global Note that is being
exchanged or transferred.

          Until the Regulation S Temporary Global Note is exchanged for
interests in the Global Notes or for Certificated Notes, the Holder thereof
shall not be entitled to receive payments of interest thereon; until so
exchanged in full, the Regulation S Temporary Global Note shall in all other
respects be entitled to the same benefits as other Notes under the Indenture.

          (f) Private Placement Legend. Upon the transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Note
registrar shall deliver Notes that do not bear the Private Placement Legend.
Upon the transfer, exchange or replacement of Notes bearing the Private
Placement Legend, the Note registrar shall deliver only Notes that bear the
Private Placement Legend unless (i) such Notes have been sold pursuant to a
registration statement which has been declared effective under the Securities
Act of 1933 or (ii) there is delivered to the Note 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 of
1933.

                                      -35-



          (g) 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 Note registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 2.09 of this Indenture
or this Section 2.05. The Company shall have the right to inspect and make
copies of all such letters, notices or other written communications at any
reasonable time during the Note registrar's normal business hours upon the
giving of reasonable prior written notice to the Note registrar.

          Section 2.06. Temporary Notes.
                        ---------------

          Pending the preparation of definitive Notes, the Company may execute
and the Trustee shall authenticate and deliver temporary Notes (printed,
lithographed or typewritten) of any authorized denomination and substantially in
the form of the definitive Notes, but with or without a recital of specific
redemption prices and with such omissions, insertions and variations as may be
appropriate for temporary Notes, all as may be determined by the Company.
Temporary Notes may contain such reference to any provisions of this Indenture
as may be appropriate. Every temporary Note shall be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
the same effect, as the definitive Notes. Without unnecessary delay the Company
will execute and deliver to the Trustee definitive Notes and thereupon any or
all temporary Notes may be surrendered in exchange therefor, at the office or
agency to be maintained by the Company in accordance with the provisions of
Section 4.02, and the Trustee shall authenticate and deliver in exchange for
such temporary Notes an equal aggregate principal amount of definitive Notes.
Until so exchanged, the temporary Notes shall in all respects be entitled to the
same benefits under this Indenture, and shall be subject to the same provisions
hereof, as definitive Notes authenticated and delivered hereunder.

          Section 2.07. Mutilated, destroyed, lost or stolen Notes.
                        ------------------------------------------

          In case any temporary or definitive Note shall become mutilated or be
destroyed, lost or stolen, the Company shall execute, and upon its request the
Trustee shall authenticate and deliver, a new Note bearing a number, letter or
other distinguishing symbol not contemporaneously outstanding in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the
Note so destroyed, lost or stolen, or, instead of issuing a substituted Note, if
any such Note shall have matured or shall be about to mature or shall have been
selected for redemption or if the Company shall have received a Change of
Control Purchase Notice or an Asset Sale Purchase Notice in respect of any such
Note (unless such notice has been withdrawn in accordance with Section 3.06 or
4.14, respectively), the Company may pay the same without surrender thereof
except in the case of a mutilated Note. In every case the applicant for a
substituted Note or for such payment shall furnish to the Company and to the
Trustee such security or indemnity as may be required by them to save each of
them harmless, and, in every case of destruction, loss or theft, the applicant
shall also furnish to the Company and to the Trustee evidence to their
satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof. The Trustee may authenticate any such substituted Note and deliver the
same, or the Trustee or any paying agent of the Company may make any such
payment, upon the written request or authorization of any officer of the
Company. Upon the issuance of any substituted Note, the Company may require the
payment of a sum sufficient to cover any tax, assessment or other governmental
charge that may be imposed in relation thereto and any other expenses connected
therewith. Every substituted Note issued pursuant to the provisions of this
Section 2.07 shall constitute an additional contractual obligation of the
Company whether or not the destroyed, lost or stolen Note shall be found at any
time, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued 

                                      -36-



hereunder. All Notes shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Notes, and shall preclude (to the extent
lawful) any and all other rights or remedies, notwithstanding any law or statute
existing or hereafter enacted to the contrary with respect to the replacement or
payment of negotiable instruments or other securities without their surrender.

          Section 2.08. Cancellation of surrendered Notes.
                        ---------------------------------

          All Notes surrendered for the purpose of payment, redemption or
purchase by the Company at the option of the holder, or exchange, substitution
or registration of transfer, shall, if surrendered to the Company or any paying
agent or Note registrar, be delivered to the Trustee and the same, together with
Notes surrendered to the Trustee for cancellation, shall be cancelled by it, and
no Notes shall be issued in lieu thereof except as expressly permitted by any of
the provisions of this Indenture. The Trustee shall destroy cancelled Notes and
shall deliver certificates of destruction thereof to the Company. If the Company
shall purchase or otherwise acquire any of the Notes, however, such purchase or
acquisition shall not operate as a payment, redemption or satisfaction of the
indebtedness represented by such Notes unless and until the Company, at its
option, shall deliver or surrender the same to the Trustee for cancellation.

          Section 2.09. Restrictive Legends.
                        -------------------

          Each Global Note and Certificated Note that constitutes a Restricted
Security shall bear the following legend (the "Private Placement Legend") on the
face thereof until the second anniversary of the Issue Date (or such shorter
period permitted by Rule 144(k) under the Securities Act of 1933 (or any
successor provision)), unless otherwise agreed by the Company and the holder
thereof:

          THIS NOTE WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM
     REGISTRATION UNDER SECTION 5 OF THE SECURITIES ACT OF 1933, AS AMENDED (THE
     "SECURITIES ACT"), AND THIS NOTE OR ANY INTEREST OR PARTICIPATION HEREIN
     MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED IN THE ABSENCE
     OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM OR NOT
     SUBJECT TO REGISTRATION. EACH PURCHASER OF THIS NOTE IS HEREBY NOTIFIED
     THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF
     SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A OR REGULATION S
     THEREUNDER. THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF THE COMPANY
     THAT (A) SUCH NOTE MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (1)
     TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED
     INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT),
     PURCHASING FOR ITS OWN ACCOUNT IN A TRANSACTION MEETING THE REQUIREMENTS OF
     RULE 144A UNDER THE SECURITIES ACT, (2) OUTSIDE THE UNITED STATES TO A
     FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF REGULATION S
     UNDER THE SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION FROM REGISTRATION
     UNDER THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER (IF AVAILABLE) OR
     (4) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS
     OF THE SECURITIES ACT (AND, IN THE CASE OF ANY RESALE, PLEDGE OR TRANSFER
     PURSUANT TO (1), (2), (3) OR (4), BASED UPON AN OPINION OF COUNSEL
     REASONABLY SATISFACTORY TO THE COMPANY IF THE COMPANY SO REQUESTS), (5) TO
     THE COMPANY OR, (6) PURSUANT TO AN EFFECTIVE

     EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS NOTE OF
     THE TRANSFER RESTRICTIONS SET FORTH IN (A) ABOVE. NO REPRESENTATION CAN BE
     MADE AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR
     RESALE OF THE SECURITY EVIDENCED HEREBY.

The Global Note shall also bear the following legend on the face thereof:

          UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN
     DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE
     DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (THE "DEPOSITORY"), TO A
     NOMINEE OF THE DEPOSITORY, OR BY ANY SUCH NOMINEE OF THE DEPOSITORY TO THE

     INDENTURE.

          Section 2.10. Book-Entry Provisions for Global Note and Regulation S

treated by the Company, the Trustee and any agent of the Company or the Trustee
as the absolute owner of the Global Note and the Regulation S Temporary Global

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 

                                      -38-

holder of any Note.

          (b) Transfers of the Global Note or the Regulation S Temporary Global
Note shall be limited to transfers in whole, but not in part, to the Depository,
its successors or their respective nominees. Interests of beneficial owners in
the Global Note or Regulation S Temporary Global Note may be transferred or
exchanged for Certificated Notes in accordance with the rules and procedures of
the Depository and the provisions of Section 2.05 of this Indenture. In
addition, Certificated Notes shall be transferred to all beneficial owners in
exchange for their beneficial interests (1) in the Global Note, if (i) the

Depository for the Global Note and a successor depositary is not appointed by
the Company within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Note registrar has received a written request

beneficial interest in the Global Note or Regulation S Temporary Global Note to
beneficial owners pursuant to paragraph (b) above, the Note registrar shall (if
one or more Certificated Notes are to be issued) reflect on its books and
records the date and a decrease in the principal amount of the Global Note or
Regulation S Temporary Global Note, as applicable, in an amount equal to the
principal amount of the beneficial interest in the Global Note or Regulation S
Temporary Global Note, as applicable, to be transferred, and the Company shall
execute, and the Trustee shall authenticate and deliver, one or more
Certificated Notes of like tenor and amount.

          (d) In connection with the transfer of the entire Global Note or

                        REDEMPTION AND PURCHASES OF NOTES

          Section 3.01. Optional Redemption.
                        -------------------

          The Company may not redeem the Notes before December 15, 2002. On or
after December 15, 2002, the Notes will be redeemable on at least 15 and not
more than 60 days' notice, at the option of the Company, in whole at any time or
in part from time to time, at the following redemption prices (expressed as a
percentage of principal amount), together with accrued and unpaid interest to
the date fixed for redemption, if redeemed during the 12-month period beginning
December 15, of the years indicated below:

                                          REDEMPTION
           YEAR                              PRICE
           2002.............................108.000%
           2003.............................105.333%
           2004.............................102.667%
           2005 and thereafter..............100.000%

          In the case of a partial redemption, the Trustee shall select the
Notes or portions thereof for redemption in such manner as it deems appropriate
and fair. The Notes may be redeemed in part in multiples of $1,000 only. The
Notes will not have the benefit of any sinking fund.

          Section 3.02. Notice of redemption; selection of Notes.
                        ----------------------------------------

          In case the Company shall desire to exercise such right to redeem all
or, as the case may be, any part of the Notes in accordance with the right
reserved so to do, the Company, or, at the Company's request, the Trustee in the
name and at the expense of the Company, shall fix a date for redemption and give
notice of such redemption to holders of the Notes to be redeemed as provided in
Section 3.01 and this Section 3.02.

          Notice of redemption shall be given to the holders of Notes to be
redeemed as a whole or in part by mailing by first-class mail a notice of such
redemption as provided in Section 3.01 to their last addresses as they shall
appear upon the registry books of the Company, but any failure to give such
notice by mailing to the holder of any Note designated for redemption as a whole
or in part, or any defect therein, shall not affect the validity of the
proceedings for the redemption of any other Notes.

          Any notice which is mailed in the manner herein and in Section 3.01
provided shall be conclusively presumed to have been duly given, whether or not
the holder receives the notice.

          Each such notice of redemption shall specify the total principal
amount to be redeemed, the date fixed for redemption and the redemption price at
which Notes are to be redeemed, and shall state that payment of the redemption
price of the Notes to be redeemed will be made at the office or agency to be
maintained by the Company in accordance with the provisions of Section 4.02,
upon presentation and surrender of such Notes, that interest accrued to the date
fixed for redemption will be paid as specified in said notice, and that on and
after said date interest thereon will cease to accrue and that the only
remaining right of the noteholder is to receive payment of the redemption price
plus such accrued interest upon surrender. If less than all the Notes are to be
redeemed, the notice of redemption to each holder also shall state the aggregate
principal amount of Notes to be redeemed and shall identify the Notes of such

                                      -40-



holder to be redeemed. In case any Note is redeemed in part only, the notice
which relates to such Note shall state the portion of the principal amount
thereof to be redeemed (which shall be $1,000 or an integral multiple thereof),
and shall state that on and after the date fixed for redemption, upon surrender
of such Note, the holder will receive, without charge, a new Note or Notes of
authorized denominations in the principal amount thereof remaining unredeemed.
Each notice shall give the name and address of each paying agent.

          On or prior to the date fixed for redemption specified in the notice
of redemption given as provided in this Section 3.02, the Company will deposit
with the Trustee or with one or more paying agents (or, if the Company is acting
as its own paying agent, set aside, segregate and hold in trust as provided in
Section 4.04(c)) an amount of money sufficient to redeem on the date fixed for
redemption all the Notes or portions of Notes so called for redemption (other
than Notes or portions thereof called for redemption on that date which have
been delivered by the Company to the Trustee for cancellation) at the applicable
redemption price, together with accrued interest to the date fixed for
redemption.

          If less than all the Notes then outstanding are to be redeemed, the
Company shall give the Trustee, at least 20 days (or such shorter period
acceptable to the Trustee) in advance of the last date upon which notice of
redemption may be given, notice of such date and of the aggregate principal
amount of Notes to be redeemed, and thereupon the Trustee shall select in such
manner as it shall deem appropriate and fair, in its sole discretion, the Notes
or portions thereof to be redeemed and shall thereafter promptly notify the
Company of the Notes or portions thereof to be redeemed within a sufficient
period of time in order that the notice provisions in Sections 3.01 and 3.02 may
be satisfied.

          Section 3.03. When Notes called for redemption become due and payable.
                        -------------------------------------------------------

          If the giving of notice of redemption shall have been completed as
provided in Sections 3.01 and 3.02, the Notes or portions of Notes specified in
such notice shall become due and payable on the date and at the place stated in
such notice at the applicable redemption price, together with interest accrued
to the date fixed for redemption, and on and after such date fixed for
redemption (unless the Company shall default in the payment of such Notes at the
applicable redemption price, together with interest accrued to the date fixed
for redemption) interest on the Notes or portions of Notes so called for
redemption shall cease to accrue whether or not such Notes are presented for
payment and such Notes or portions thereof shall be deemed not to be outstanding
hereunder and shall not be entitled to any right or benefit hereunder except to
receive payment of the applicable redemption price plus accrued interest to the
redemption date. On presentation and surrender of such Notes for redemption at
said place of payment in said notice specified on or after the date fixed for
redemption, the said Notes shall be paid and redeemed by the Company at the
applicable redemption price, together with interest accrued to the date fixed
for redemption. If the date fixed for redemption is an interest payment date,
such payment shall not include accrued interest, which interest shall be paid in
the usual manner otherwise provided for herein. Upon presentation of any Note
which is redeemed in part only, the Company shall execute and register, and the
Trustee shall authenticate and deliver to the holder thereof at the expense of
the Company, a new Note or Notes in principal amount equal to the unredeemed
portion of the Note so presented.

          Section 3.05. Purchase of Notes at option of the holder upon Change of
                        --------------------------------------------------------
Control.
- -------

          (a) If on or prior to maturity, there shall have occurred a Change of
Control, the Company shall offer to purchase each Note at a purchase price in
cash equal to 101% of the principal amount thereof plus accrued and unpaid
interest to the Change of Control Purchase Date (the "Change of Control Purchase
Price"), on the date that is 30 Business Days after the occurrence of the Change
of Control (the "Change of Control Purchase Date"), subject to the satisfaction
by or on behalf of the holder of the requirements set forth in Section 3.05(c).
Following a Change of Control, the Company shall not be obligated to purchase
any Notes pursuant to this Section 3.05(a) or give any notice under Section
3.05(b) with respect to any subsequent Change of Control. The Company's
obligation to purchase Notes as provided hereunder shall for all purposes hereof
be satisfied by, and shall cease upon, the deposit of funds with the Trustee as
provided for in Section 3.07.

          A "Change of Control" means the occurrence of any of the following
(whether or not otherwise in compliance with the provisions of this Indenture):
(i) the sale, lease, transfer, conveyance or other disposition, in one or a
series of related transactions, of all substantially all of the assets of the
Company and its Subsidiaries taken as a whole to any "person" (as such term is
used in Section 13(d)(3) of the Exchange Act) other than the Company and/or one
or more Wholly-Owned Subsidiaries, (ii) the adoption of a plan relating to the
complete liquidation or dissolution of the Company, (iii) the consummation of
any transaction (including, without limitation, any merger or consolidation) as
a result of which Brett E. Wilcox is no longer the sole beneficial owner (as to
both voting and dispositive power) of at least a majority of the Voting Stock of
the Company, provided that such event shall not constitute a "Change of Control"
if Brett E. Wilcox (x) is the sole beneficial owner (as to both voting and
dispositive power) of at least 35% of the Voting Stock of the Company, and (y)
is the Chief Executive Officer of the Company and (z) has the sole right (not
subject to revocation, termination or expiration prior to the scheduled maturity
of the Notes) to elect a majority of the Board of Directors of the Company;
provided, further, that the immediately preceding proviso shall not be available
if any other "person" (as defined above) is the beneficial owner (as to either
voting or dispositive power) of 35% or more of the Voting Stock of the Company
or (iv) the first day on which a majority of the members of the Board of
Directors of the Company are not Continuing Directors. For purposes of this
provision, "Continuing Directors" means, as of any date of determination, any
member of the Board of Directors of the Company who (i) was a member of such
Board of Directors on the date of this Indenture or (ii) was nominated for
election or elected or appointed to such Board of Directors by the Board of
Directors of the Company at a time when a majority of the Board (excluding any
member whose service terminated as result of death) consisted of Continuing
Directors.

          "Voting Stock" means, with respect to any Person, the Capital Stock of
such Person having general voting power under ordinary circumstances to elect at
least a majority of the board of directors, managers or trustees of such Person
(irrespective of whether or not at the time Capital Stock of any other class or
classes shall have or might have voting power by reason of the happening of any
contingency).

          (b) Within ten Business Days after the occurrence of a Change of
Control, the Company shall mail a written notice of Change of Control by
first-class mail to the Trustee and to each holder (and to beneficial owners as
required by applicable law, including without limitation Rule 13e-4 of the
Exchange Act, if applicable) and shall cause a copy of such notice to be
published in a daily newspaper of national circulation. The notice shall include
a form of Change of Control Purchase Notice (as described below) to be completed
by the holder and shall state:

          (1) the events causing a Change of Control and the date of such Change
of Control;

                                      -42-

          (2) the date by which the Change of Control Purchase Notice pursuant
to this Section 3.05 must be given;

          (3) the Change of Control Purchase Date;

          (4) the Change of Control Purchase Price;

          (5) the name and address of the Trustee and the office or agency
referred to in Section 4.02;

          (6) that the Notes must be surrendered to the Trustee or the office or
agency referred to in Section 4.02 to collect payment;

          (7) that the Change of Control Purchase Price for any Note as to which
a Change of Control Purchase Notice has been duly given and not withdrawn will
be paid promptly following the later of the Change of Control Purchase Date and
the time of surrender of such Note as described in clause (6);

          (8) the procedures the holder must follow to exercise rights under
this Section 3.05 and a brief description of those rights; and

          (9) the procedures for withdrawing a Change of Control Purchase
Notice. (c) To accept the offer to purchase Notes described in Section 3.05(a),
a holder must deliver a written notice of purchase (a "Change of Control
Purchase Notice") to the Trustee or to the office or agency referred to in
Section 4.02 at any time prior to the close of business on the Business Day
immediately preceding the Change of Control Purchase Date, stating:

          (1) the name of the holder;

          (2) the certificate number or numbers of the Note or Notes in respect
of which the Change of Control Purchase Notice is being submitted, the original
principal amount of such Note or Notes, and the portion of the principal amount
of such Note or Notes which the holder will deliver to be purchased, which
portion must be $1,000 or an integral multiple thereof; and

          (3) that the offer to purchase is being accepted.

          The delivery of the Note, by hand or by registered mail prior to, on
or after the Change of Control Purchase Date (together with all necessary
endorsements), to the Trustee or to the office or agency referred to in Section
4.02 shall be a condition to the receipt by the holder of the Change of Control
Purchase Price therefor; provided, however, that such Change of Control Purchase
Price shall be so paid pursuant to this Section 3.05 only if the Note so
delivered to the Trustee or such office or agency shall conform in all respects
to the description thereof set forth in the related Change of Control Purchase
Notice; and provided, further, that the Company shall have no obligation to
purchase any Notes with respect to which the Change of Control Purchase Notice
has not been received by the Company prior to the close of business on the
Business Day immediately preceding the Change of Control Purchase Date.

          In the event that the offer to purchase described in Section 3.05(a)
shall be accepted in accordance with the terms hereof, the Company shall
purchase from the holder thereof, pursuant to this Section 3.05, a portion of a
Note if the principal amount of such portion is $1,000 or an integral multiple
of $1,000. Provisions of this Indenture that apply to the purchase of all of a
Note also apply to the 

                                      -43-



purchase of such portion of such Note. Upon presentation of any Note that is
purchased in part only, the Company shall execute and register, and the Trustee
shall authenticate and deliver to the holder thereof at the expense of the
Company, a new Note or Notes in principal amount equal to the unpurchased
portion of the Note so presented.

          Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.05 shall be consummated by the delivery by the Trustee or other
paying agent of the consideration to be received by the holder promptly
following the later of the Change of Control Purchase Date and the time of
delivery of the Note.

          Notwithstanding anything herein to the contrary, any holder delivering
to the Trustee or to the office or agency referred to in Section 4.02 the Change
of Control Purchase Notice contemplated by this Section 3.05(c) shall have the
right to withdraw such Change of Control Purchase Notice by delivery of a
written notice of withdrawal to the Trustee or to such office or agency in
accordance with Section 3.06 at any time prior to the close of business on the
Business Day next preceding the Change of Control Purchase Date.

          Section 3.06. Effect of Change of Control Purchase Notice.
                        -------------------------------------------

          Upon receipt by the Company of the Change of Control Purchase Notice
specified in Section 3.05(c), the holder of the Note in respect of which such
Change of Control Purchase Notice was given shall (unless such Change of Control
Purchase Notice is withdrawn as specified in the following paragraph) thereafter
be entitled to receive solely the Change of Control Purchase Price with respect
to such Note. Such Change of Control Purchase Price shall be due and payable as
of the Change of Control Purchase Date and shall be paid to such holder promptly
following the later of (x) the Change of Control Purchase Date (provided the
conditions in Section 3.05(c), as applicable, have been satisfied) and (y) the
date of delivery of such Note to the Trustee or to the office or agency referred
to in Section 4.02 by the holder thereof in the manner required by Section
3.05(c).

          A Change of Control Purchase Notice may be withdrawn by means of a
written notice of withdrawal delivered to the office of the Trustee or to the
office or agency referred to in Section 4.02 at any time on or prior to the
close of business on the Business Day next preceding the Change of Control
Purchase Date, specifying:

          (1) the certificate number or numbers of the Note or Notes in respect
of which such notice of withdrawal is being submitted;

          (2) the portion of the principal amount of such Note or Notes with
respect to which such notice of withdrawal is being submitted; and

          (3) the portion, if any, of the principal amount of such Note or Notes
that remains subject to the original Change of Control Purchase Notice, and
which has been or will be delivered for purchase by the Company. 

There shall be no purchase of any Notes pursuant to Section 3.05 if there has
occurred (prior to, on or after, as the case may be, the giving, by the holders
of such Notes, of the required Change of Control Purchase Notice) and is
continuing an Event of Default (other than a default in the payment of the
Change of Control Purchase Price with respect to such Notes).

                                      -44-



          Section 3.07. Deposit of Change of Control Purchase Price.
                        -------------------------------------------

          On or prior to the Change of Control Purchase Date, the Company shall
deposit with the Trustee or other paying agent (or, if the Company is acting as
paying agent, shall segregate and hold in trust as provided in Section 4.04(c))
an amount of cash in immediately available funds sufficient to pay the aggregate
Change of Control Purchase Price of all the Notes or portions thereof which are
to be purchased on the Change of Control Purchase Date. Upon such deposit, the
Company shall be deemed to have satisfied its obligations to purchase Notes
pursuant to Section 3.05. If cash sufficient to pay the Change of Control
Purchase Price of all Notes or portions thereof to be purchased on the Change of
Control Purchase Date is deposited with the Trustee or other paying agent as of
the Change of Control Purchase Date, interest shall cease to accrue (whether or
not any such Note is delivered to the Trustee or any other office or agency
maintained for such purpose) on such Notes (or portions thereof) on and after
the Change of Control Purchase Date, and the holders thereof shall have no other
rights as such (other than the right to receive the Change of Control Purchase
Price, upon surrender of such Notes).

          Section 3.08. Covenant to comply with securities laws upon purchase of
                        --------------------------------------------------------
Notes.
- -----

          In connection with any offer to purchase or any purchase of securities
under Section 3.05 hereof, the Company shall (i) comply with Rule 14e-1
promulgated under the Exchange Act (or any successor provision thereof), if
applicable, and (ii) otherwise comply with all federal and state securities laws
regulating the purchase of the Notes so as to permit the rights and obligations
under Sections 3.05 and 3.06 to be exercised in the time and in the manner
specified in Sections 3.05 and 3.06.

          Section 3.09. Repayment to the Company.
                        ------------------------

          The Trustee shall return to the Company any cash, together with
interest or dividends, if any, thereon (subject to the provisions of Section
7.05), held by it for the payment of the Change of Control Purchase Price of the
Notes that remain unclaimed as provided in Section 12.07 hereof; provided,
however, that to the extent that the aggregate amount of cash deposited by the
Company pursuant to Section 3.07 exceeds the aggregate Change of Control
Purchase Price of the Notes or portions thereof to be purchased on the Change of
Control Purchase Date, then promptly after the Change of Control Purchase Date,
the Trustee shall return any such excess to the Company together with interest
or dividends, if any, thereon (subject to the provisions of Section 7.05) no
later than two Business Days following the expiration of the period commencing
on the Change of Control Purchase Date and ending on the 91st day after such
date, provided that the Trustee shall in no event be required to release or
deliver such excess cash if an Event of Default under Section 6.01(h) or 6.01(i)
(or an event that, after notice or lapse of time, or both, would become an Event
of Default) shall have occurred during such period and be continuing.

                                  ARTICLE FOUR
                       PARTICULAR COVENANTS OF THE COMPANY

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

          The Company will duly and punctually pay or cause to be paid the
principal of, and premium, if any, Change of Control Purchase Price, Asset Sale
Purchase Price and interest on, each of the Notes at the time and place such
amounts may become due and payable and in the manner provided 

                                      -45-

paying agent other than the Trustee, the Company shall send written notification
to the Trustee describing the payment made and certifying that it was duly and
punctually made.

          Until the Regulation S Temporary Global Note is exchanged for
interests in the Global Notes or for Certificated Notes, the Holder thereof
shall not be entitled to receive payments of interest thereon; until so
exchanged in full, the Regulation S Temporary Global Note shall in all other
respects be entitled to the same benefits as other Notes under the Indenture.

maintain an office or agency in the Borough of Manhattan, City of New York,

demands to or upon the Company in respect to the Notes or of this Indenture may
be served, and where the Notes may be presented or surrendered for payment,
redemption or purchase. The Company may also from time to time designate one or
more other offices or agencies for any or all such purposes and may from time to
time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in the Borough of Manhattan, City of New York, State of New
York for such purposes. The Company will give to the Trustee notice of the
location of any such office or agency and of any change of location thereof. In
case the Company shall fail to maintain any such office or agency or shall fail
to give such notice of the location or of any change in the location thereof,
such surrenders, presentations and demands may be made and notices may be served
at the principal office of the Trustee in San Francisco, California, and the

before each due date of the principal of, or premium, if any, Change of Control
Purchase Price, Asset Sale Purchase Price or interest on, the Notes, set aside,
segregate and hold in trust for the benefit of the Persons entitled thereto, a
sum sufficient to pay such principal, premium, if any, Change of Control

          (a) The Company shall not, and shall not permit any of its
Subsidiaries to, enter into any transaction or series of related transactions
with any Affiliate or Unrestricted Subsidiary of the Company, unless:

               (i) the terms thereof are no less favorable to the Company or

               (ii) if the amount of such transaction or the aggregate amount of
     such series of related transactions is greater than $1,000,000, such

acquisition or retirement for value of, any Indebtedness of the Company or any
of its Subsidiaries that is subordinated (pursuant to its terms) in right and
priority of payment to the Notes or any Guarantee, provided that any Subsidiary
of the Company may pay, prepay, purchase, redeem or otherwise acquire or retire
any such Indebtedness of such Subsidiary payable to the Company or any other
Wholly-Owned Subsidiary (each of the foregoing in clauses (i), (ii) and (iii), a
"Restricted Payment"), (iv) make or permit any of its Subsidiaries to make any
Restricted Investment, or (v) make or permit any of its Subsidiaries to make any
Unrestricted Subsidiary Investment, unless at the time of, and immediately after
giving effect to, each such Restricted Payment, Restricted Investment or
Unrestricted Subsidiary Investment:

          (A) no Event of Default (or event that, after notice or lapse of time,
     or both, would become an Event of Default) shall have occurred and be
     continuing; and

          (B) the Consolidated Fixed Charge Coverage Ratio of the Company is
     greater than 2.0 to 1, in the case of any Restricted Payment, Restricted
     Investment or Unrestricted Subsidiary Investment made prior to December 15,
     2001, and 2.25 to 1, in the case of any Restricted Payment, Restricted
     Investment or Unrestricted Subsidiary Investment made on or after December
     15, 2001; and

          (C) the sum of:

                    (x) the aggregate amount expended for all Restricted
               Payments after the date of this Indenture,

                    (y) the aggregate amount expended for all Restricted
               Investments after the date of this Indenture (less (1) to the
               extent any Restricted Investment made after the date of this
               Indenture is sold for or otherwise liquidated or repaid in cash,
               the lesser of the cash return of capital with respect to such
               Restricted Investment (less the cost of disposal, if any) and the
               initial amount of such Restricted Investment, and (2) the amount
               of any guarantee or similar contingent obligation that
               constitutes a Restricted Investment made after the date of this
               Indenture, to the extent it has been released), and

                                      -49-

                    (z) the aggregate amount of Unrestricted Subsidiary
               Investments Outstanding (in each case, the amount expended for
               such Restricted Payments, Restricted Investments and Unrestricted
               Subsidiary Investments, if paid in property other than in cash or
               a sum certain guaranteed, to be the Fair Market Value of such
               property), would not exceed the sum of:

                         (I) 50% of the Consolidated Net Income of the Company
                    (or, if the aggregate Consolidated Net Income of the Company
                    for any such period shall be a deficit, minus 100% of such
                    deficit) accrued on a cumulative basis for the period (taken
                    as one accounting period) from January 1, 1999 to the end of
                    the Company's most recently ended fiscal quarter for which
                    financial statements are available at the time such
                    Restricted Payment, Restricted Investment or Unrestricted
                    Subsidiary Investment is being made, and

                         (II) the aggregate net proceeds, including the Fair
                    Market Value of property other than cash, received by the
                    Company as capital contributions to the Company (other than
                    from a Subsidiary or an Unrestricted Subsidiary of the
                    Company) after the date of this Indenture, or from the issue
                    or sale (other than to a Subsidiary or an Unrestricted
                    Subsidiary of the Company), after the date of the Indenture,
                    of Capital Stock of the Company other than Disqualified
                    Stock (excluding any net proceeds of a Qualified Equity
                    Offering to the extent used to redeem any part of the
                    Notes), or from the issue or sale (other than to a
                    Subsidiary or an Unrestricted Subsidiary of the Company),
                    after the date of the Indenture, of any debt or other
                    security of the Company convertible or exercisable into such
                    Capital Stock that has been so converted or exercised, and

                         (III) 50% of any dividends or other distributions
                    consisting of cash received by the Company or a Wholly-Owned
                    Subsidiary after the date of this Indenture from any
                    Unrestricted Subsidiary to the extent that such dividends or
                    other distributions are not required to reduce the amount of
                    the Unrestricted Subsidiary Investments Outstanding to zero.

               (b) The foregoing provisions of this Section 4.09 shall not be
     violated by reason of:

                    (i) the payment of any dividend or distribution or the
     redemption of any securities within 60 days after the date of declaration
     of such dividend or distribution or the giving of the formal notice by the
     Company of such redemption, if at said date of declaration of such dividend
     or distribution or the giving of the formal notice of such redemption, such
     dividend, distribution or redemption would have complied with Section
     4.09(a);

                    (ii) the retirement of any shares of the Company's Capital
     Stock by exchange for, or out of the proceeds of, the substantially
     concurrent sale (other than to a Subsidiary or an Unrestricted Subsidiary
     of the Company) of other shares of its Capital Stock other than
     Disqualified Stock or out of the proceeds of a substantially concurrent
     capital contribution to the Company (other than by a Subsidiary or an
     Unrestricted Subsidiary of the Company); provided, however, that, to the
     extent the proceeds are so used, such sale of Capital Stock or capital

                                      -50-

     contribution shall be excluded in determining the aggregate net proceeds
     received by the Company referred to under clause (II) of Section 4.09(a);

                    (iii) the payments provided for by clauses (ii) and (iii) of
     Section 4.08(b); (iv) principal payments (whether regularly scheduled or
     otherwise) on, or any prepayment, purchase, redemption or other acquisition
     or retirement for value of, Indebtedness of the Company or any of its
     Subsidiaries that is subordinated (pursuant to its terms) in right and
     priority of payment to the Notes or any Guarantee with the proceeds from
     the substantially concurrent Incurrence of any Refinancing Indebtedness in
     respect thereof permitted by clause (vi) of Section 4.10(b) (other than
     Refinancing Indebtedness payable to the Company or any of its Subsidiaries
     or Unrestricted Subsidiaries); provided, however, that, to the extent the
     proceeds are so used, such proceeds, upon any conversion of such
     Refinancing Indebtedness into Capital Stock, shall not be included in
     determining the aggregate net proceeds received by the Company referred to
     under clause (II) of Section 4.09(a);

                    (v) principal payments (whether regularly scheduled or
     otherwise) on, or any prepayment, purchase, redemption or other acquisition
     or retirement for value of, any Indebtedness of the Company or any of its
     Subsidiaries that is subordinated (pursuant to its terms) in right and
     priority of payment to the Notes or any Guarantee by exchange for, or out
     of the proceeds of, the substantially concurrent sale (other than to a
     Subsidiary or an Unrestricted Subsidiary of the Company) of Capital Stock
     of the Company other than Disqualified Stock or out of the proceeds of a
     substantially concurrent capital contribution to the Company (other than by
     a Subsidiary or an Unrestricted Subsidiary of the Company); provided,
     however, that, to the extent the proceeds are so used, such sale of Capital
     Stock or capital contribution shall be excluded in determining the
     aggregate net proceeds received by the Company referred to under clause
     (II) of Section 4.09(a);

                    (vi) (y) from time to time during or following the end of
     any fiscal quarter during which the Company is an S Corporation, cash
     distributions by the Company to its shareholders in an amount equal to the
     maximum amount sufficient to cover payment of the expected federal and
     state income taxes attributable to the direct or indirect ownership of the
     Company's common stock, based on the highest federal and state income tax
     rates that could be applicable to any holder of such common stock, as
     determined through the end of the fiscal quarter in question plus any
     penalties or interest thereon, and (z) if, subsequent to any year in which
     the Company or any Subsidiary of the Company was an S Corporation any
     taxing authority or court of competent jurisdiction shall finally determine
     (including by way of settlement or stipulation) that additional federal or
     state income taxes or any penalties or interest thereon are payable by the
     holders of the Company's or such Subsidiary's common stock in respect of
     income of the Company or such Subsidiary during such year, cash
     distributions to such holders in an additional amount sufficient to pay
     such additional federal or state income taxes plus any penalties or
     interest thereon; provided, however, that, in the case of either clause (a)
     or (b), in no event shall amounts so distributed after the date of the
     Indenture in respect of any year exceed the actual amount of federal and
     state income taxes (including any penalties or interest thereon), or
     additional income taxes (including any penalties or interest thereon), as
     the case may be, for such year on the income attributable to the ownership
     of the Company's or such Subsidiary's common stock; provided, further, that
     for purposes of clause (a)(C)(z)(I) above, Consolidated Net Income of the
     Company shall be reduced by an amount equal to any cash distributions made
     in respect of any penalties or interest in connection with any federal and
     state income taxes in accordance 

                                      -51-



     with clause (vi)(a) or (b) hereof;

                    (vii) the repurchase by GHC of shares of its preferred stock
     outstanding on the date of this Indenture; provided, however, that the
     aggregate amount paid to repurchase such preferred stock does not exceed
     $30,500,000, plus any accrued and unpaid dividends thereon; and provided,
     further, that, immediately after giving effect to such repurchase (x) no
     Event of Default (or event that, with notice or lapse of time, or both,
     would constitute an Event of Default) shall exist and (y) the Company could
     Incur $1.00 of Indebtedness pursuant to Section 4.10(a) hereof; and

                    (viii) the making by the Company or any Subsidiary of the
     Company of Restricted Payments in addition to those permitted by any other
     clause of this Section 4.09(b) or by Section 4.09(a) in an aggregate amount
     not exceeding $1,000,000.

No payments and other transfers made under clauses (ii) through (vii) (except as
provided in clause (vi)) of this Section 4.09(b) shall reduce the amount
available for Restricted Payments, Restricted Investments and Unrestricted
Subsidiary Investments under Section 4.09(a). Payments made under clause (i) or
(viii) and as specified in clause (vi) of this Section 4.09(b) shall reduce the
amount available for Restricted Payments, Restricted Investments and
Unrestricted Subsidiary Investments under Section 4.09(a).

          The Board of Directors of the Company may designate a Subsidiary of
the Company to be an Unrestricted Subsidiary, provided that certain conditions
specified in the definition of "Unrestricted Subsidiary" are met. For purposes
of making such determination, all outstanding Unrestricted Subsidiary
Investments by the Company and its Subsidiaries in the Unrestricted Subsidiary
so designated will be deemed to be Unrestricted Subsidiary Investments
Outstanding at the time of such designation and will reduce the amount available
for Restricted Payments, Restricted Investments and Unrestricted Subsidiary
Investments under Section 4.09(a). All such Unrestricted Subsidiary Investments
will be deemed to have been made at the time of such designation and to be in an
amount equal to the greater of (A) the net book value of such Unrestricted
Subsidiary Investments at the time of such designation and (B) the Fair Market
Value of such Unrestricted Subsidiary Investments at the time of such
designation. Such designation will only be permitted if such Unrestricted
Subsidiary Investments would be permitted at such time and if such Subsidiary
otherwise meets the conditions specified in the definition of an Unrestricted
Subsidiary.

          Section 4.10. Limitation on Indebtedness.
                        --------------------------

          (a) The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or become liable with respect to, or extend the maturity of or become liable for
the payment of, contingently or otherwise (collectively, "Incur"), any
Indebtedness, except that, without duplication, the Company may Incur
Indebtedness (and the Subsidiaries of the Company may guarantee such
Indebtedness) if, after giving effect thereto and the receipt and application of
the proceeds therefrom, the Consolidated Fixed Charge Coverage Ratio of the
Company is greater than 2.0 to 1, in the case of Indebtedness Incurred prior to
December 15, 2001, and 2.25 to 1, in the case of Indebtedness Incurred on or
after December 15, 2001.

          (b) Notwithstanding Section 4.10(a), the following shall be permitted:

               (i) Indebtedness Incurred by the Company and its Subsidiaries in
     respect of the Notes;

               (ii) Indebtedness Incurred by any of the Subsidiaries of the
     Company under 

                                      -52-



     the Credit Agreement in an aggregate original principal amount (with
     letters of credit and bankers' acceptances being deemed to have a principal
     amount equal to the maximum reimbursement obligations with respect thereto)
     at any one time outstanding not to exceed the greater of (1) $90,000,000 or
     (2) the then amount of the Borrowing Base;

               (iii) Indebtedness Incurred by the Company under the Hydro
     Agreement in an aggregate original principal amount not to exceed
     $30,000,000, and guarantees by the Subsidiaries of the Company of such
     Indebtedness;

               (iv) Indebtedness Incurred by any of the Subsidiaries of the
     Company payable to the Company or any Wholly-Owned Subsidiary;

               (v) Indebtedness Incurred by a Person prior to the date upon
     which it becomes a Subsidiary of the Company (excluding Indebtedness
     Incurred by such Person in connection with, or in contemplation of, it
     becoming a Subsidiary of the Company), provided that the holders of such
     Indebtedness do not have at any time, in respect thereof, direct or
     indirect recourse to any property or assets of the Company and its
     Subsidiaries other than the property and assets of such acquired Person and
     its Subsidiaries;

               (vi) Indebtedness ("Refinancing Indebtedness") Incurred by the
     Company or any of its Subsidiaries that serves to Refinance, in whole or in
     part, any Indebtedness permitted by this Section 4.10(b) (other than by
     clause (iv) or (viii) hereof) or by Section 4.10(a) (the "Refinanced
     Indebtedness"), or any one or more successive Refinancings of any thereof;
     provided, however, that:

               (A) such Refinancing Indebtedness is in an aggregate amount not
          to exceed the aggregate amount of such Refinanced Indebtedness
          (including accrued interest thereon and, in the case of Refinanced
          Indebtedness Incurred under the Credit Agreement, undrawn amounts
          under revolving credit arrangements thereunder otherwise permitted to
          be Incurred pursuant to clause (ii)(B) of this Section 4.10(b)), the
          amount of any premium required to be paid in connection with such
          Refinancing pursuant to the terms of such Refinanced Indebtedness or
          the amount of any reasonable and customary premium determined by the
          Company to be necessary to accomplish such Refinancing by means of a
          redemption, tender offer, privately negotiated transaction, defeasance
          or other similar transaction, and an amount equal to the reasonable
          fees and expenses in connection with the Incurrence of such
          Refinancing Indebtedness;

               (B) neither the Company nor any of its Subsidiaries is an obligor
          of such Refinancing Indebtedness, except to the extent that such
          Person (1) was an obligor of such Refinanced Indebtedness or (2) is
          otherwise permitted, at the time such Refinancing Indebtedness is
          Incurred, to be an obligor of such Refinancing Indebtedness; and

               (C) in the case of any Refinanced Indebtedness that is
          subordinated (pursuant to its terms) in right and priority of payment
          to the Notes or any Guarantee, such Refinancing Indebtedness (1) has a
          final maturity and weighted average maturity at least as long as such
          Refinanced Indebtedness and (2) is subordinated (pursuant to its
          terms) in right and priority of payment to the Notes or such
          Guarantee, as the case may be, at least to the same extent as such
          Refinanced Indebtedness;

                                      -53-

               (vii) Indebtedness Incurred by the Company or NAC or NAS to fund
     capital improvements projects at NAC or NAS in an aggregate original
     principal amount not to exceed $15,000,000, and guarantees by the
     Subsidiaries of the Company of such Indebtedness, provided that such
     Indebtedness and such guarantees are subordinated in right and priority of
     payment to the Notes and the Guarantees on terms no less favorable to the
     Holders of the Notes than those applicable to the Indebtedness under the
     Hydro Agreement and the guarantees thereof as in effect on the date of this
     Indenture, and further provided that such Indebtedness has a final maturity
     date no earlier than one year following the stated maturity of the Notes
     and provides for payments of principal and interest on terms no less
     favorable to the holders of the Notes than those contained in the Hydro
     Agreement;

               (viii) Indebtedness Incurred by the Company or any of its
     Subsidiaries pursuant to Aluminum Hedging Obligations entered into in the
     ordinary course of business and not for speculative purposes in reasonable
     relation to the Company's or such Subsidiary's business; and

               (ix) other Indebtedness Incurred by the Company in an aggregate
     principal amount which does not exceed $5,000,000 at any time outstanding,
     and guarantees by Subsidiaries of the Company of such Indebtedness.

          The Board of Directors of the Company may designate an Unrestricted
Subsidiary to be a Subsidiary of the Company, provided that certain conditions
specified in the definition of "Unrestricted Subsidiary" are met. Any such
redesignation shall be deemed to be an Incurrence by the Company or its
Subsidiaries of the Indebtedness (if any) of such redesignated Subsidiary, to
the extent that such Indebtedness does not already constitute Indebtedness of
the Company or one of its Subsidiaries for purposes of this covenant as of the
date of such redesignation. Any Indebtedness of any other Person existing at the
time such Person becomes a Subsidiary of the Company or secured by a Lien
encumbering any assets acquired by the Company or any Subsidiary of the Company
shall be deemed, for purposes of this Section 4.10 (other than clause (v) of
Section 4.10(b)), to be Incurred at the time such Person becomes a Subsidiary or
at the time such assets are acquired, as the case may be.

          (c) The Company shall not, and shall not permit any of its
Subsidiaries to, Incur any Indebtedness that is subordinated (pursuant to its
terms) in right and priority of payment to any other Indebtedness of the Company
or its Subsidiaries unless such Indebtedness is also subordinated (pursuant to
its terms) in right and priority of payment to the Notes and the Guarantees on
substantially identical terms; provided, however, that no Indebtedness of the
Company or any Subsidiary of the Company shall be deemed to be subordinated in
right and priority of payment to any other Indebtedness of the Company or such
Subsidiary solely by virtue of being unsecured or unguaranteed.

          (d) For the purpose of determining compliance with this Section 4.10,
in the event that any Indebtedness is permitted to be Incurred pursuant to more
than one clause of Section 4.10(b), the Incurrence of such Indebtedness shall
not limit the amount of Indebtedness otherwise permitted to be Incurred, and
shall not be required to be included under more than one such clause.

          Section 4.11. Limitation on Liens.
                        -------------------

          (a) The Company shall not, and shall not permit any of its
Subsidiaries to, create, incur, assume or suffer to exist any Lien upon any of
its assets (including without limitation the Pledged Shares) to secure, directly
or indirectly, any Indebtedness or obligations other than the Notes, unless the
Notes are equally and ratably secured on a senior basis for so long as such
secured Indebtedness or 

                                      -54-



     obligations are so secured.

          (b) Notwithstanding anything to the contrary, this Section 4.11 shall
not prohibit:

               (i) Liens on the assets of the Subsidiaries of the Company (other
     than the Collateral) securing Indebtedness under the Credit Agreement
     permitted by clause (ii) of Section 4.10(b);

               (ii) Liens on the Collateral securing Indebtedness under the
     Hydro Agreement permitted by clause (iii) of Section 4.10(b), provided that
     such Liens are subordinated to the Liens on the Collateral on terms
     substantially identical to those in effect on the date of this Indenture;

               (iii) Liens in favor of the Company or any Wholly-Owned
     Subsidiary;

               (iv) Liens on assets of a Person existing at the time such Person
     is merged into or consolidated with the Company or any Subsidiary of the
     Company, provided that such Liens were not created in connection with, or
     in contemplation of, such merger or consolidation and do not extend to any
     other assets (other than Improvements thereto or thereon and any proceeds
     thereof) of the Company or any Subsidiary of the Company;

               (v) Liens on assets existing at the time of acquisition thereof
     by the Company or any Subsidiary of the Company, provided that such Liens
     were not created in connection with, or in contemplation of, such
     acquisition and do not extend to any other assets (other than Improvements
     thereto or thereon and any proceeds thereof) of the Company or any
     Subsidiary of the Company;

               (vi) Liens securing Refinancing Indebtedness permitted by clause
     (vi) of Section 4.10(b) and Incurred to Refinance, or successively
     Refinance, any Indebtedness secured by Liens permitted by this Section
     4.11(b) (other than by clause (iii) or (viii) hereof), provided that the
     Liens securing such Refinancing Indebtedness do not encumber any assets
     (which may be by category or type) of the Company or any Subsidiary of the
     Company other than those securing the Indebtedness so Refinanced;

               (vii) Permitted Liens; and

               (viii) Liens on assets of the Company or its Subsidiaries (other
     than the Pledged Shares), in addition to those permitted by clauses (i)
     through (vii), securing Indebtedness or obligations in an aggregate amount
     at any time outstanding not exceeding $5,000,000.

          (c) For purposes of this Section 4.11, the Notes will be considered
equally and ratably secured on a senior basis with any other Lien if the Lien
securing the Notes is of at least equal priority and covers the same assets as
such other Lien, provided that, if the Indebtedness or obligations secured by
such other Lien are expressly subordinated in right and priority of payment by
their terms to the Notes or any Guarantee, the Lien securing the Notes will be
senior to such other Lien.

          (d) For the purpose of determining compliance with this Section 4.11,
in the event that any Lien is permitted pursuant to more than one clause of
Section 4.11(b), such Lien shall not limit any other Lien otherwise permitted,
and shall not be required to be included under more than one such clause.

          If any Person becomes a Subsidiary of the Company after the date of
this Indenture (including as a result of any merger, consolidation or other
acquisition or any designation by the Board of Directors of the Company), the
Company shall (i) execute and deliver to the Trustee, and cause each such Person
(and, in the event the Company owns any of the Capital Stock of such Person
indirectly through one or more other Subsidiaries of the Company, each such
other Subsidiary) to execute and deliver to the Trustee, a supplemental
indenture complying with the requirements of this Indenture satisfactory in form
to the Trustee pursuant to which (A) such Person will be named as an additional
Subsidiary of the Company subject as such to the terms of this Indenture,
including without limitation Article Fifteen hereof, and (B) all of the issued
and outstanding Capital Stock of such Person owned by the Company or any
Subsidiary of the Company (together with all income, benefits and rights derived
therefrom and all proceeds thereof) will become subject to the Pledge under this
Indenture, and (ii) deliver or cause such other Subsidiaries to deliver to the
Trustee all certificates evidencing such Capital Stock, properly endorsed in
blank or accompanied by duly executed stock powers satisfactory in form to the
Trustee providing for transfer in blank.

          Section 4.13. Limitation on dividends and other payment restrictions
                        ------------------------------------------------------
affecting Subsidiaries.
- ----------------------

          The Company shall not, and shall not permit its Subsidiaries to,
create or otherwise suffer to exist any consensual encumbrances or restrictions
on the ability of any Subsidiary of the Company to pay dividends or make any
other distributions on its Capital Stock or pay any Indebtedness owed to the
Company or any other Subsidiary of the Company or to make loans or advances or
transfer any of its assets to the Company or any other Subsidiary of the
Company; provided, however, that this Section 4.13 shall not prohibit Permitted
Dividend Encumbrances.

          Section 4.14. Limitation on Asset Sales.
                        -------------------------

          (a) The Company shall not, and shall not permit any of its
Subsidiaries to, consummate any Asset Sale unless the Company or such Subsidiary
receives consideration in connection with such Asset Sale at least equal to the
Fair Market Value of the assets sold, transferred or otherwise disposed of and
at least 75% of the consideration therefor received by the Company or such
Subsidiary (exclusive of indemnities) is in the form of cash or Cash
Equivalents, provided that this sentence shall not apply to the sale or
disposition of assets as a result of a foreclosure (or a secured party taking
ownership of such assets in lieu of foreclosure) or as a result of an
involuntary proceeding in which the Company cannot, directly or through its
Subsidiaries, direct the type of proceeds received. The amount of any
liabilities of the Company or any Subsidiary of the Company (other than
contingent liabilities and liabilities that are by their terms subordinated in
right and priority of payment to the Notes or any Guarantee) that are actually
assumed by the transferee in such Asset Sale pursuant to a customary novation
agreement that releases the Company and its Subsidiaries from further liability
shall be deemed to be cash for purposes of determining the percentage of cash
consideration received by the Company or its Subsidiaries.

          (b) The Company shall apply any Net Cash Proceeds received after the
date of this Indenture to (i) the prepayment of any Indebtedness of the Company
(other than the Notes or the Indebtedness under the Credit Agreement (or any
Refinancing Indebtedness Incurred in any Refinancing, or successive Refinancing,
thereof)) entitled to receive payment pursuant to the terms thereof (excluding
Indebtedness that by its terms is subordinated in right and priority of payment
to the Notes or any 

                                      -56-



Guarantee) (the "Specified Pari Passu Indebtedness"), unless the holders thereof
elect not to receive such prepayment (provided that, in the event any such
Indebtedness was Incurred under a revolving credit arrangement, such prepayment
shall be accompanied by a permanent reduction of the commitment in respect
thereof), and (ii) an offer to purchase (an "Asset Sale Offer") the then
outstanding Notes, on any Business Day occurring no later than 305 days after
the receipt by the Company (or any of its Subsidiaries, if applicable) of such
Net Cash Proceeds (the "Asset Sale Purchase Date," which date shall be deferred
to the extent necessary to permit the Asset Sale Offer to remain open for the
period required by applicable law), at a price (the "Asset Sale Purchase Price")
equal to 100% of the principal amount thereof together with accrued and unpaid
interest, if any, to the Asset Sale Purchase Date pursuant to the provisions set
forth below. Such Asset Sale Offer with respect to the Notes shall be in an
aggregate principal amount (the "Asset Sale Offer Amount") equal to the Net Cash
Proceeds (rounded down to the nearest $1,000) from the Asset Sales to which the
Asset Sale Offer relates multiplied by a fraction, the numerator of which is the
principal amount of the Notes outstanding (determined as of the close of
business on the day immediately preceding the date notice of such Asset Sale
Offer is mailed) and the denominator of which is the principal amount of the
Notes outstanding plus the aggregate principal amount of Specified Pari Passu
Indebtedness outstanding (determined as of the close of business on the day
immediately preceding the date notice of such Asset Sale Offer is mailed). If
(x) no Specified Pari Passu Indebtedness is outstanding or (y) the holders of
such Indebtedness entitled to receive payment elect not to receive the payments
provided for in the previous sentence, or (z) the application of such Net Cash
Proceeds results in the complete prepayment of such Indebtedness, then in each
case any remaining portion of such Net Cash Proceeds will be required to be
applied to an Asset Sale Offer to purchase the Notes.

          (c) Notice of an Asset Sale Offer shall be mailed by the Company to
all holders at their last registered address within 275 days of the receipt by
the Company or any of its Subsidiaries of such Net Cash Proceeds. The Asset Sale
Offer shall remain open from the time of mailing until the last Business Day
before the Asset Sale Purchase Date, but in no event for a period less than the
greater of (a) 24 days or (b) that required by applicable law. The notice shall
state:

          (1) that the Asset Sale Offer is being made pursuant to this Section
4.14;

          (2) the Asset Sale Offer Amount, the Asset Sale Purchase Price and the
Asset SalePurchase Date;

          (3) the name and address of the Trustee and that Notes must be
surrendered to the Trustee to collect the Asset Sale Purchase Price;

          (4) that any Note not tendered or accepted for payment will continue
to accrue interest;

          (5) that any Note accepted for payment pursuant to the Asset Sale
Offer shall cease to accrue interest on and after the Asset Sale Purchase Date;

          (6) that each holder electing to have a Note purchased pursuant to an
Asset Sale Offer will be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the Note (the "Asset Sale Purchase
Notice") completed, to the Trustee at the address specified in the notice at
least five Business Days before the Asset Sale Purchase Date;

          (7) that holders will be entitled to withdraw their election if the
Trustee receives, not later than one Business Day prior to the Asset Sale
Purchase Date, a telegram, telex, facsimile 

                                      -57-



transmission or letter setting forth the name of the holder, the principal
amount of the Notes the holder delivered for purchase, the certificate number of
each Note the holder delivered for purchase and a statement that such holder is
withdrawing his, her or its election to have such Notes purchased;

          (8) that if Notes in a principal amount in excess of the Asset Sale
Offer Amount are surrendered pursuant to the Asset Sale Offer, the Company shall
purchase Notes 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 acquired); and

          (9)(x) that Notes may be purchased in whole or in part (in
denominations of $1,000 or integral multiples thereof) and (y) that holders
whose Notes are purchased only in part will be issued new Notes equal in
principal amount to the unpurchased portion of the Notes surrendered.

          On or before the Asset Sale Purchase Date, the Company shall (i)
accept for payment Notes (having denominations of $1,000 or integral multiples
thereof) surrendered pursuant to the Asset Sale Offer (on a pro rata basis if
required pursuant to paragraph (c)(8) above), (ii) deposit by 10:30 a.m., New
York City time, on the Asset Sale Purchase Date with the Trustee money in
immediately available funds sufficient to pay the Asset Sale Purchase Price of
all Notes or portions thereof so accepted and (iii) deliver Notes so accepted to
the Trustee together with an Officers' Certificate stating the Notes or portions
thereof accepted for payment by the Company. The Trustee shall promptly mail or
deliver to holders of Notes so accepted payment in an amount equal to the Asset
Sale Purchase Price, and the Company shall execute and the Trustee shall
promptly authenticate and mail or deliver to such holders a new Note equal in
principal amount to any unpurchased portion of the Note surrendered. Any Notes
not so accepted shall be promptly mailed or delivered to the holder thereof. The
Company will publicly announce the results of the Asset Sale Offer on, or as
soon as practicable after, the Asset Sale Purchase Date.

          Notwithstanding the foregoing, the Company shall not be required to
make an Asset Sale Offer until the aggregate amount of Net Cash Proceeds so to
be applied pursuant to this Section 4.14 exceeds $10,000,000, and then the total
amount of such Net Cash Proceeds shall be required to be so applied in
accordance with this Section 4.14. In no event shall any Net Cash Proceeds that
are applied to an Asset Sale Offer be required to be applied to more than one
Asset Sale Offer.

          (d) Notwithstanding the provisions of clauses (a) and (b) of this
Section 4.14, the Company shall have no obligation to make an Asset Sale Offer
pursuant to this Section 4.14 if, and to the extent, the Company or any of its
Subsidiaries commits within 270 days of the receipt of such Net Cash Proceeds to
reinvest (whether by acquisition of an existing business or expansion, including
without limitation capital expenditures) such Net Cash Proceeds in one or more
of the lines of business (including capital expenditures) in which the Company
or its Subsidiaries were engaged on the date of this Indenture or any business
reasonably related or ancillary thereto, provided that such Net Cash Proceeds
are substantially so utilized or irrevocably committed to be so utilized no
later than 365 days following receipt of such Net Cash Proceeds.

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

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

to, engage in any businesses other than lines of business in which the Company
or any of its Subsidiaries is engaged on the date of this Indenture and any
business reasonably related or ancillary thereto (as determined in good faith by
the Company's Board of Directors).

                        ------------------------------------------------------
Subsidiaries.
- ------------

          The Company shall not, and shall not permit any of its Subsidiaries
to, sell, transfer or otherwise dispose of any Capital Stock of any Subsidiary
to any Person if as a result of such sale, transfer or disposition such
Subsidiary shall cease to be a Subsidiary, and will provide further that any
such permitted sale, transfer or disposition shall comply with the terms of this
Indenture (including without limitation Section 4.14 hereof).

          Section 4.18. Payments for consent.
                        --------------------

          The Company shall not, and shall not permit any of its Subsidiaries or
Unrestricted Subsidiaries to, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any holder
of a Note for or as an inducement to any consent, waiver or amendment of any of
the terms or provisions of the Indenture, the Notes or any Guarantee, unless
such consideration is offered to be paid or is paid to all holders of the Notes
that so consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or amendment.

          Section 4.19. No Amendment to Subordination Provisions.
                        ----------------------------------------

any way that will (i) increase the rate of or change the time for payment of

any Hydro Subordinated Debt and (iii) alter the redemption provisions or the
price or terms at which the Company is required to offer to purchase such Hydro
Subordinated Debt without the consent of the Holders of at least a majority in
aggregate principal amount of the Notes then outstanding. The Company shall not
agree or consent to or take any other act to affect the subordination of the

                                  ARTICLE FIVE
                      NOTEHOLDERS' LISTS AND REPORTS BY THE
                             COMPANY AND THE TRUSTEE

          Section 5.01. Company to furnish Trustee information as to names and
                        ------------------------------------------------------
addresses of noteholders.
- ------------------------

          The Company will furnish or cause to be furnished to the Trustee:

          (a) semi-annually, not more than 15 days after each record date for
the payment of interest, a list, in such form as the Trustee may reasonably
require, of the names and addresses of the noteholders as of such record date,
and

          (b) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished; 

provided, however, that so long as the Trustee is the Note registrar, no such
list shall be required to be furnished.

          Section 5.02. Preservation and disclosure of lists.
                        ------------------------------------

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the holders of
Notes (1) contained in the most recent list furnished to it as provided in
Section 5.01 and (2) received by it in the capacity of paying agent (if so
acting) or Note registrar. The Trustee may destroy any list furnished to it as
provided in Section 5.01 upon receipt of a new list so furnished.

          (b) In case three or more holders of Notes (hereinafter referred to as
"applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Note for a period of at
least six months preceding the date of such application, and such application
states that the applicants desire to communicate with other holders of Notes
with respect to their rights under this Indenture or under the Notes, and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, at its election either

          (1) afford such applicants access to the information preserved at the
time by the Trustee in accordance with the provisions of subsection (a) of this
Section 5.02, or

          (2) inform such applicants as to the approximate number of holders of
Notes whose names and addresses appear in the information preserved at the time
by the Trustee in accordance with the provisions of subsection (a) of this
Section 5.02, and as to the approximate cost of mailing to such noteholders the
form of proxy or other communication, if any, specified in such application. 

                                      -60-



If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each noteholder whose name and address appears in the information
preserved at the time by the Trustee in accordance with the provisions of
Section 5.02(a), a copy of the form of proxy or other communication which is
specified in such request, with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of mailing, unless within five days after
such tender the Trustee shall mail to such applicants and file with the
Commission, together with a copy of the material to be mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would
be contrary to the best interests of the holders of Notes or would be in
violation of applicable law. Such written statement shall specify the basis of
such opinion. After opportunity for hearing upon the objections specified in the
written statement so filed, the Commission may, and if demanded by the Trustee
or by such applicants shall, enter an order either sustaining one or more of
such objections or refusing to sustain any of them. If the Commission shall
enter an order refusing to sustain any of such objections, or if, after the
entry of an order sustaining one or more of such objections, the Commission
shall find, after notice and opportunity for hearing, that all objections so
sustained have been met, and shall enter an order so declaring, the Trustee
shall mail copies of such material to all noteholders with reasonable promptness
after the entry of such order and the renewal of such tender; otherwise the
Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

          (c) Each and every holder of a Note, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee nor any paying agent nor the Note registrar shall be held accountable by
reason of the disclosure of any such information as to the names and addresses
of the holders of Notes in accordance with the provisions of Section 5.02(b),
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under said subsection (b), nor shall any such disclosure be
deemed a violation of existing law, or any law hereafter enacted which does not
specifically refer to Section 312 of the Trust Indenture Act of 1939.

          Section 5.03. Reports by the Company.
                        ----------------------

          (a) Whether or not the Company is subject to the reporting

subject to verification by accountants.

                                      -61-



          (c) The Company covenants and agrees to transmit to the holders of

year end), a brief certificate from the principal executive officer, principal
financial officer or principal accounting officer as to his or her knowledge of
the Company's compliance with all conditions and covenants under this Indenture.
For purposes of this paragraph (d), such compliance shall be determined without
regard to any period of grace or requirement of notice provided under this
Indenture.

          (e) For so long as any Restricted Securities remain outstanding, the
Company and its Subsidiaries covenant and agree to furnish to the holders of the
Notes and to securities analysts and prospective investors, upon their request,
the information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act of 1933.

          (f) The Company covenants and agrees to furnish to the Trustee, at
least annually after the execution and delivery of this Indenture (but always
within 105 days after the Company's fiscal year end), an Opinion of Counsel
either stating that in the opinion of the counsel rendering the same such action
has been taken with respect to the recording, filing, re-recording and refiling
of this Indenture as is necessary to maintain the lien of this Indenture, and
reciting the details of such action, or stating that in the opinion of such
counsel no such action is necessary to maintain such lien.

          Section 5.04. Reports by the Trustee.
                        ----------------------

          (a) On or before May 15, 1999, and on or before May 15 in every year
thereafter, so long as any Notes are outstanding hereunder, the Trustee, if
required to do so by the provisions of the Trust Indenture Act of 1939, shall
transmit to the noteholders, as hereinafter in this Section 5.04 provided, a
brief report dated as of March 15 of the year in which such report is made with

the Trustee (as such) which remain unpaid on the date of such report, and for
the reimbursement of which it claims or may claim a lien or charge, prior to
that of the Notes, on any property or funds held or collected by it as Trustee,
except that the Trustee shall not be required (but may elect) to state such
advances if such advances so remaining unpaid aggregate not more than 0.5% of
the principal amount of the Notes outstanding on the date of such report;

          (4) the amount, interest rate, and maturity date of all other
Indebtedness owing by the Company (or by any other obligor on the Notes) to the

                                      -62-



such report, with a brief description of any property held as collateral
security therefor, except an Indebtedness based upon a creditor relationship
arising in any manner described in paragraph (2), (3), (4) or (6) of subsection
(b) of Section 7.13;

          (5) any change to the property and funds, if any, physically in the
possession of the Trustee (as such) on the date of such report; and

opinion materially affects the Notes, except action in respect of a default,
notice of which has been or is to be withheld by it in accordance with the
provisions of Section 6.07.

          (b) The Trustee shall transmit to the noteholders, as hereinafter
provided, a brief report with respect to the description and amount of any
advances (and if the Trustee elects so to state, the circumstances surrounding
the making thereof) made by the Trustee (as such) since the date of the last
report transmitted pursuant to the provisions of Section 5.04(a) (or if no such
report has yet been so transmitted, since the date of execution of this
Indenture), for the reimbursement of which it claims or may claim a lien or
charge prior to that of the Notes on property or funds held or collected by it
as Trustee, and which it has not previously reported pursuant to this
subsection, except that the Trustee shall not be required (but may elect) to
report such advances if such advances remaining unpaid at any time aggregate 10%
or less of the principal amount of Notes outstanding at such time, such report
to be transmitted within 90 days after such time.

          (c) Reports pursuant to this Section 5.04 shall be transmitted by mail

upon the registry books of the Company, (ii) to all noteholders who have, within
the two years preceding such transmission, filed their names and addresses with
the Trustee for that purpose, and (iii) except in the case of reports pursuant
to Section 5.04(b), to all holders of Notes whose names and addresses have been
furnished to or obtained by the Trustee pursuant to Section 5.01.

          (d) A copy of each such report shall, at the time of such transmission
to noteholders, be filed by the Trustee with each stock exchange (if any) upon
which the Notes are listed or admitted for trading and also with the Commission.
The Company will notify the Trustee when and as the Notes become listed on any
stock exchange.

                               ON EVENT OF DEFAULT

          Section 6.01. Events of Default defined.

on which written notice of such failure, which notice must specify the failure,
demand it be remedied and state that the notice is a "Notice of Default," shall
have been given to the Company by the Trustee (which notice the Trustee may give
at its discretion and shall give upon receipt of requests to do so by the
holders of at least 25% of the aggregate principal amount of the Notes at the
time outstanding) or to the Company and the Trustee by the holders of at least
25% of the aggregate principal amount of the Notes at the time outstanding; or

          (e) a default under any mortgage, indenture, or instrument under which
there may be issued or by which there may be secured or evidenced any
Indebtedness of the Company or any of its Subsidiaries, whether such
Indebtedness now exists or shall hereafter be created, which default (i) in the
case of a failure to make payment on any such Indebtedness, shall not have been
waived, cured or otherwise ceased to exist prior to the expiration of the
applicable grace period provided with respect to such Indebtedness, or (ii) in
the case of any default other than a payment default referred to in clause (i),
shall have resulted in such Indebtedness becoming or being declared due and
payable prior to the date on which it would otherwise have become due and
payable; provided, however, that the aggregate principal amount of all such
Indebtedness in respect of which any such default exists exceeds $10,000,000; or

          (f) breach by the Company or any Guarantor of any material
representation or warranty set forth in the Security Agreements, or, subject to
notice and grace periods set forth in the applicable Security Agreements,
default by the Company or any Guarantor in the performance of any covenant set
forth in the Security Agreements, or repudiation by the Company or any Guarantor
of its obligations under the Security Agreements or the unenforceability of the

          (g) a final judgment which, together with other outstanding final
judgments against the Company and its Subsidiaries, exceeds an aggregate of
$10,000,000 (to the extent such judgments are not covered by valid and
collectible insurance from solvent unaffiliated insurers or uncontested
indemnification from solvent unaffiliated indemnitors) shall be entered against
the Company and/or its Subsidiaries and within 60 days after entry thereof,
judgments exceeding such amount shall not have been discharged, settled or
bonded or execution thereof stayed pending appeal or, within 60 days after the
expiration of any such stay, such judgments exceeding such amount shall not have
been discharged, settled or bonded or execution thereof further stayed; or

          (h) a court having jurisdiction in the premises shall have entered a
decree or order for relief against the Company or any of its Subsidiaries in an
involuntary case under any applicable bankruptcy, insolvency or other similar
law now or hereafter in effect, or appointing a receiver, liquidator, assignee,
custodian, trustee (other than a trustee under a deed of trust), sequestrator
(or similar official) of the Company or any of its Subsidiaries or for all or
any substantial part of the property of the Company or any of its Subsidiaries,
or ordering the winding-up or liquidation of the affairs of the Company or any

                                      -64-



of its Subsidiaries, and such decree or order shall have remained unstayed and
in effect for a period of 90 consecutive days; or

          (i) the Company or any of its Subsidiaries shall have commenced a
voluntary case under any applicable bankruptcy, insolvency or other similar law
now or hereafter in effect, or shall have consented to the entry of an order for
relief in an involuntary case under any such law, or shall have consented to the
appointment of or taking possession by a receiver, liquidator, assignee, trustee
(other than a trustee under a deed of trust), custodian, sequestrator (or
similar official) of the Company or such Subsidiary or for all or any
substantial part of its property, or shall have made an assignment for the
benefit of creditors, or shall have taken any corporate action in furtherance of
any of the foregoing; or

          (j) other than pursuant to Section 15.05, a Guarantee shall be held to
be unenforceable or invalid with respect to any Subsidiary of the Company by a
final non-appealable order or judgment issued by a court of competent
jurisdiction or shall cease for any reason to be in full force and effect with
respect to any Subsidiary of the Company, or any Subsidiary of the Company or
any Person acting by or on behalf of any Subsidiary of the Company shall deny or
disaffirm its obligations under its Guarantee; 

then, in the case of an Event of Default specified in clause (a), (b), (c), (d),
(e), (f) or (i), and in each and every such case, unless the principal of all
the Notes shall have already become due and payable, either the Trustee or the
holders of not less than 25% of the aggregate principal amount of the Notes then
outstanding, by notice in writing to the Company (and to the Trustee if given by
noteholders), may, and the Trustee shall if requested to do so by the holders of
not less than 25% of the aggregate principal amount of the Notes then
outstanding hereunder, declare the principal amount and accrued interest to the
date of declaration of all the Notes to be due and payable immediately. Upon any
such declaration the same shall become and shall be immediately due and payable,
anything in this Indenture or in the Notes contained to the contrary
notwithstanding. If an Event of Default specified in clause (g) or (h) above
occurs, such amount shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any
noteholder. 

In the case of any Event of Default occurring by reason of any willful action
(or inaction) taken (or not taken) by or on behalf of the Company with the
intention of avoiding payment of the premium that the Company would have had to
pay if the Company then had elected to redeem the Notes pursuant to the optional
redemption provisions of the Indenture, an equivalent premium shall also become
and be immediately due and payable to the extent permitted by law upon the
acceleration of the Notes. If an Event of Default occurs prior to December 15,
2002 by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to December 15, 2002, then, upon acceleration of
the Notes, an additional premium shall also become and be immediately due and
payable in an amount, for each of the years beginning on December 15 of the
years set forth below, a set forth below (expressed as a percentage of the
principal amount of the Notes on the date of payment that would otherwise be due
but for the provisions of this sentence):

     Year                                                    Percentage

          Section 6.02. Payment of Notes on default; suit therefor.
                        ------------------------------------------

          The Company covenants that (1) in case default shall be made in the
payment of any installment of interest on any of the Notes, as and when the same
shall become due and payable, and such default shall have continued for a period
of 30 days, or (2) in case default shall be made in the payment of the principal
of, or premium, if any, Change of Control Purchase Price or Asset Sale Purchase
Price on, any of the Notes when the same shall have become due and payable,
whether upon maturity of the Notes or upon redemption or purchase by the Company
or upon declaration or otherwise, then, upon demand of the Trustee, the Company
will pay to the Trustee, for the benefit of the holders of the Notes, the whole
amount that then shall have become due and payable on all such Notes for such
amounts, as the case may be, with interest upon the overdue principal, premium,
if any, Change of Control Purchase Price or Asset Sale Purchase Price, as the
case may be, and installments of interest (to the extent permitted by law) at
the rate of interest borne by the Notes; and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including a reasonable compensation to the Trustee, its agents, attorneys and
counsel, and any expense or liabilities incurred by the Trustee hereunder other
than through its negligence or willful misconduct.

          In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor upon the
Notes, and collect in the manner provided by law out of the property of the
Company or any other obligor upon the Notes wherever situated the moneys
adjudged or decreed to be payable.

          In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor upon the Notes under any
applicable bankruptcy, insolvency or similar law or in case a receiver or
trustee (other than a trustee under a deed of trust) shall have been appointed
for the property of the Company or such other obligor, or in case of any other
similar judicial proceedings relative to the Company or any other obligor upon
the Notes, or to creditors or property of the Company or such other obligor, the
Trustee, irrespective of whether the principal, Change of Control Purchase Price
or Asset Sale Purchase Price, as the case may be, of or on the Notes shall then
be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 6.02, shall be entitled and empowered by intervention
in such proceedings or otherwise to file and prove a claim or claims for the
whole amount of principal, premium, if any, Change of Control Purchase Price,
Asset Sale Purchase Price and interest owing and unpaid in respect of the Notes,
and to file such other papers or documents as may be necessary or advisable in
order to have the claims of the Trustee and of the noteholders allowed in any
judicial proceeding relative to the Company or any other obligor upon the Notes,
its creditors, or its property, and to collect and receive any moneys or other
property payable or deliverable on any such claims, and to distribute the same
after the deduction of its reasonable charges and expenses; and any receiver,
assignee or trustee in bankruptcy or reorganization is hereby authorized by each
of the noteholders 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 it for compensation and
expenses, including reasonable counsel fees incurred by it up to the date of
such distributio. To the extent that such payment of reasonable compensation,
expenses, liabilities and counsel fees out of the estate in any such proceedings
shall be denied for any reason, payment of the same shall be secured by a lien
on, and shall be paid out of, any and all distributions, dividends, moneys,
securities and other property 

                                      -66-



which the holders of the Notes may be entitled to receive in such proceedings,
whether in liquidation or under any plan of reorganization or arrangement or
otherwise.

          All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes, or the production thereof on any trial or other proceeding
relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment, subject to the payment of the reasonable expenses,
disbursements and compensation of the Trustee, its agents and attorneys, shall
be for the ratable benefit of the holders of the Notes.

          Section 6.03. Application of moneys collected by Trustee.
                        ------------------------------------------

          Any moneys collected by the Trustee pursuant to this Article Six or
pursuant to the Subordination Agreement shall be applied to the payment of all
amounts due the Trustee pursuant to Section 7.06, and thereafter in the order
following, at the date or dates fixed by the Trustee for the distribution of
such moneys, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof if fully paid:

     FIRST: In case no principal of, or Change of Control Purchase Price or
     Asset Sale Purchase Price on, the outstanding Notes shall have become due
     and be unpaid, to the payment of interest on the Notes, in the order of the
     maturity of the installments of such interest, with interest upon the
     overdue installments of interest (so far as permitted by law and to the
     extent that such interest has been collected by the Trustee) at the rate of
     interest borne by the Notes, such payments to be made ratably to the
     Persons entitled thereto, without discrimination or preference;

     SECOND: In case any principal of, or Change of Control Purchase Price or
     Asset Sale Purchase Price on, the outstanding Notes shall have become due,
     by declaration or otherwise, to the payment of the whole amount then owing
     and unpaid upon the Notes for principal, premium, if any, Change of Control
     Purchase Price, Asset Sale Purchase Price and interest, as the case may be,
     with interest on the overdue principal, premium, if any, Change of Control
     Purchase Price, Asset Sale Purchase Price and installments of interest (so
     far as permitted by law and to the extent that such interest has been
     collected by the Trustee), as the case may be, at the rate of interest
     borne by the Notes; and in case such moneys shall be insufficient to pay in
     full the whole amount so due and unpaid upon the Notes, then to the payment
     of such principal, premium, if any, Change of Control Purchase Price, Asset
     Sale Purchase Price and interest, without preference or priority of any one
     such applicable amount over another, or of any installment of interest over
     any other installment of interest, ratably to the aggregate of such
     principal, premium, if any, Change of Control Purchase Price, Asset Sale
     Purchase Price and accrued and unpaid interest; and

     THIRD: To the payment of the remainder, if any, to the Company, its
     successors or assigns, or to whosoever may be lawfully entitled to receive
     the same, or as a court of competent jurisdiction may direct.

          Section 6.04. Limitation on suits by holders of Notes.
                        ---------------------------------------

          No holder of any Note shall have any right by virtue or by availing of
any provision of this Indenture or the Subordination Agreement to institute any
suit, action or proceeding or to seek any remedy in equity or at law upon or
under or with respect to this Indenture, the Notes or the Subordination
Agreement or for the appointment of a receiver or trustee, or for any other
remedy, unless such holder 

                                      -67-



previously shall have given to the Trustee written notice of default and of the
continuance thereof, as hereinabove provided, and unless also the holders of not
less than 25% of the aggregate principal amount of the Notes then outstanding
shall have made written request upon the Trustee to institute such action, suit
or proceeding or to seek such remedy in its own name as Trustee hereunder and
shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby,
and the Trustee, for 60 days after its receipt of such notice, request and offer
of indemnity, shall have neglected or refused to institute any such action, suit
or proceeding and no direction inconsistent with such written request shall have
been given to the Trustee pursuant to Section 6.06; it being understood and
intended, and being expressly covenanted by the taker and holder of every Note
with every other taker and holder and the Trustee, that no one or more holders
of Notes shall have any right in any manner whatever by virtue or by availing of
any provision of this Indenture or the Subordination Agreement to affect,
disturb or prejudice the rights of the holders of any other of such Notes, or to
obtain or seek to obtain priority over or preference to any other such holder,
or to enforce any right under this Indenture or the Subordination Agreement,
except in the manner herein provided and for the equal, ratable and common
benefit of all holders of Notes. For the protection and enforcement of the
provisions of this Section 6.04, each and every noteholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

          Notwithstanding any other provisions in this Indenture, however, the
right of any holder of any Note to receive payment of the principal, premium, if
any, Change of Control Purchase Price, Asset Sale Purchase Price and interest,
as the case may be, of or on such Note, on or after the respective due dates
expressed in such Note, or to institute suit for the enforcement of any such
payment on or after such respective dates or to demand purchase of its Notes
pursuant to Article Three or Section 4.14, shall not be impaired or affected
without the consent of such holder.

          Section 6.05. Proceedings by Trustee; remedies cumulative and
                        -----------------------------------------------
continuing; delay or omission not waiver of default.
- ---------------------------------------------------

          In case of a default hereunder or under the Subordination Agreement,
the Trustee may in its discretion proceed to protect and enforce any of the
rights or remedies vested in it by this Indenture or by the Subordination
Agreement by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights or remedies, either by
suit in equity or by action at law or by proceeding in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained in
this Indenture or in the Subordination Agreement or in aid of the exercise of
any power granted in this Indenture or in the Subordination Agreement, or to
enforce any other legal or equitable right or remedy vested in the Trustee by
this Indenture, by the Subordination Agreement or by law. All powers and
remedies given by this Article Six or by the Subordination Agreement to the
Trustee or to the noteholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies
available to the Trustee or the holders of the Notes, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture or in the Subordination Agreement, and no
delay or omission of the Trustee or of any holder of any of the Notes to
exercise any right or power accruing upon any default occurring and continuing
as aforesaid shall impair any such right or power, or shall be construed to be a
waiver of any such default or an acquiescence therein; and, subject to the
provisions of Section 6.04, every power and remedy given by this Article Six or
by the Subordination Agreement or by law to the Trustee or to the noteholders
may be exercised from time to time, and as often as shall be deemed expedient,
by the Trustee or by the noteholders.

                                      -68-



          Section 6.06. Rights of holders of majority in principal amount of
                        ----------------------------------------------------
Notes to direct Trustee and to waive defaults.
- ---------------------------------------------

          The holders of a majority of the aggregate principal amount of the
Notes at the time outstanding (determined as provided in Section 8.04), or, if a
record date is set in accordance with Section 8.05, as of such record date,
shall have the right to direct the time, method, and place of conducting any
proceeding for any remedy available to the Trustee (including any remedy
available under this Article Six or the Subordination Agreement), or exercising
any trust or power conferred on the Trustee; provided, however, that subject to
the provisions of Section 7.01, the Trustee shall have the right to decline to
follow any such direction if the Trustee shall determine that the action so
directed may not lawfully be taken, or if the Trustee in good faith shall, by a
responsible officer or officers of the Trustee, determine that the proceedings
so directed would be illegal or involve it in personal liability or be unjustly
prejudicial to the noteholders not joining therein, and provided further that
nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by noteholders. Prior to the declaration of the
maturity of the Notes as provided in Section 6.01, the holders of a majority of
the aggregate principal amount of the Notes at the time outstanding (determined
as provided in Sections 8.04 and 8.05) may on behalf of the holders of all of
the Notes waive any past default hereunder and its consequences (including any
acceleration, other than an automatic acceleration resulting from an Event of
Default under clause (g) or (h) of Section 6.01), except a default in the
payment of principal of, or premium, if any, Change of Control Purchase Price,
Asset Sale Purchase Price or interest on, any of the Notes (other than solely as
a result of an acceleration) or a default under any covenant or provision of
this Indenture which under Article Ten cannot be modified or amended without the
consent of the holder of each outstanding Note. In the case of any such waiver
the Company, the Trustee and the holders of the Notes shall be restored to their
former positions and rights hereunder, respectively; but no such waiver shall
extend to any subsequent or other default or impair any right consequent
thereon.

          Section 6.07. Trustee to give notice of defaults known to it, but may
                        -------------------------------------------------------
withhold in certain circumstances.
- ---------------------------------

          The Trustee shall, within 90 days after the occurrence of a default
hereunder or under the Subordination Agreement, give to the noteholders, in the
manner and to the extent provided in Section 5.04(c) with respect to reports
pursuant to Section 5.04(a), notice of such defaults known to the Trustee unless
such defaults shall have been cured or waived before the giving of such notice
(the term "defaults" for the purposes of this Section 6.07 being hereby defined
to be the events specified in clauses (a), (b), (c), (d), (e), (f), (g), (h) and
(i) of Section 6.01, not including any periods of grace provided for in clauses
(a), (d), (e), (f) and (g), respectively, and irrespective of the giving of
notice specified in clause (d)); provided that, except in the case of default in
the payment of the principal of, or premium, if any, Change of Control Purchase
Price, Asset Sale Purchase Price or interest on, any of the Notes, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee, or a trust committee of directors and/or
responsible officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the noteholders. Other than
payment defaults, the Trustee shall not be deemed to have any knowledge of an
event of default unless a responsible officer has received written notice of the
same.

                                      -69-



          Section 6.08. Requirement of an undertaking to pay costs in certain
                        -----------------------------------------------------
suits under the Indenture or against the Trustee.
- ------------------------------------------------

          All parties to this Indenture agree, and each holder of any Note by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or the Subordination Agreement, or in any suit against the
Trustee for any action taken, suffered or omitted by it as Trustee, the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section 6.08 shall not apply to
any suit instituted by the Trustee, to any suit instituted by any noteholder, or
group of noteholders, holding in the aggregate more than 10% of the aggregate
principal amount of the Notes then outstanding, or to any suit instituted by any
noteholder for the enforcement of the payment of the principal of, or premium,
if any, Change of Control Purchase Price, Asset Sale Purchase Price or interest
on, any Note on or after the due date expressed in such Note.

          Section 6.09. Waiver of stay or extension laws.
                        --------------------------------

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

                                 ARTICLE SEVEN.
                             CONCERNING THE TRUSTEE

          Section 7.01. Duties and responsibilities of Trustee.
                        --------------------------------------

          The Trustee, prior to the occurrence of an Event of Default and after
the curing or waiving of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default has occurred (which has not
been cured or waived) 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 reasonable person would exercise or use under the
circumstances in the conduct of his or her own affairs.

          No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct; provided, however, that:

          (a) prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default which may have occurred:

          (1) the duties and obligations of the Trustee shall be determined
solely by the express provisions of this Indenture, and the Trustee shall not be
liable except for the performance of such duties and obligations as are
specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

                                      -70-



          (2) in the absence of willful misconduct on the part of the Trustee,
the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon any 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 that by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall determine whether or not they conform to the requirements of this
Indenture;

          (b) the Trustee shall not be liable for any error of judgment made in
good faith by a responsible officer or officers of the Trustee, unless it shall
be proved that the Trustee was negligent in ascertaining the pertinent facts;
and

          (c) the Trustee shall not be liable with respect to any action taken,
suffered or omitted to be taken by it in good faith in accordance with the
direction of the holders of not less than a majority in principal amount of the
Notes at the time outstanding (determined as provided in Section 8.04 or 8.05)
relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon
the Trustee, under this Indenture.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties hereunder or in the exercise
of any of its rights or powers, if there is reasonable ground for believing that
the repayment of such funds or adequate indemnity against such risk or liability
is not reasonably assured to it.

          Section 7.02. Reliance on documents, opinions, etc.
                        -------------------------------------

          Subject to the provisions of Section 7.01:

          (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, note or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

          (b) any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an instrument signed in the name of
the Company by the Chairman of the Board, the President, the Chief Financial
Officer or any Vice President and the Secretary or any Assistant Secretary or
the Treasurer or any Assistant Treasurer (unless other evidence in respect
thereof be herein specifically prescribed); and any resolution of the Board of
Directors of the Company may be evidenced to the Trustee by a copy thereof
certified by the Secretary or any Assistant Secretary of the Company;

          (c) the Trustee may consult with counsel and the advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in accordance with such advice or Opinion of Counsel;

          (d) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the noteholders, pursuant to the provisions of this
Indenture, unless such noteholders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that may be
incurred therein or thereby; but nothing herein contained shall, however,
relieve the Trustee of the obligation, upon the occurrence of an Event of
Default (which has not been cured or waived), to exercise such of the rights and
powers vested in it 

                                      -71-



by this Indenture, and to use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs;

          (e) the Trustee shall not be liable for any action taken, suffered or
omitted by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture;

          (f) prior to the occurrence of an Event of Default hereunder and after
the curing or waiving of all Events of Default, the Trustee shall not be bound
to make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, bond, note or other paper or document, unless requested in
writing so to do by the holders of not less than a majority in aggregate
principal amount of the Notes then outstanding (determined as provided in
Section 8.04 or Section 8.05); provided, however, that if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Indenture, the Trustee may require from the noteholders
reasonable indemnity against such expenses or liability as a condition to so
proceeding. The reasonable expenses of every such examination shall be paid by
the Company or, if paid by the Trustee, shall be repaid by the Company upon
demand; and

          (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys.

          Section 7.03. No responsibility for recitals, etc.
                        ------------------------------------

          The recitals contained herein and in the Notes (other than the
certificate of authentication on the Notes) shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for the correctness of
the same. The Trustee makes no representation as to the validity or sufficiency
of this Indenture or of the Notes. The Trustee shall not be accountable for the
use or application by the Company of any of the Notes or of the proceeds of such
Notes, or for the use or application of any moneys paid over by the Trustee in
accordance with any provision of this Indenture, or for the use or application
of any moneys received by any paying agent other than the Trustee.

          Section 7.04. Trustee, paying agent or Note registrar may own Notes.
                        -----------------------------------------------------

          The Trustee, any paying agent or Note registrar, in its individual or
any other capacity, may become the owner or pledgee of Notes with the same
rights it would have if it were not Trustee, paying agent or Note registrar.

          Section 7.05. Moneys received by Trustee to be held in trust without
                        ------------------------------------------------------
interest.
- --------

          Subject to the provisions of Section 12.07, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law or by any national securities
exchanges on which the Notes are listed or admitted for trading. The Trustee
shall be under no liability for interest on any moneys received by it hereunder
except such as it may agree with the Company to pay thereon.

                                      -72-



          Section 7.06. Compensation and expenses of Trustee.
                        ------------------------------------

          The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust), and the Company will pay or reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in connection with the acceptance or
administration of its trust under this Indenture (including the reasonable
compensation and the expenses and disbursements of its counsel and of all
Persons not regularly in its employ) except any such expense, disbursement or
advance as may arise from its negligence or willful misconduct. The Company also
covenants to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or willful misconduct on
the part of the Trustee or its agents and arising out of or in connection with
the acceptance or administration of this trust, including the costs and expenses
of defending itself against any claim of liability under this Indenture in
connection with the exercise of its powers or duties hereunder. The obligations
of the Company under this Section 7.06 to compensate the Trustee and to pay or
reimburse the Trustee for expenses, disbursements and advances shall constitute
additional Indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture or resignation or removal of the Trustee. Such
additional Indebtedness shall be secured by a Lien upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
benefit of the holders of particular Notes.

          Section 7.07. Right of Trustee to rely on Officers' Certificate where
                        -------------------------------------------------------
no other evidence specifically prescribed.
- -----------------------------------------

          Subject to the provisions of Section 7.01, whenever in the
administration of the provisions of this Indenture, the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, such matter (unless other evidence
in respect thereof be herein specifically prescribed) may, in the absence of
negligence or willful misconduct on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee, and such Officers' Certificate, in the absence of negligence or willful
misconduct on the part of the Trustee, shall be full warrant to the Trustee for
any action taken, suffered or omitted by it under the provisions of this
Indenture in reliance thereon.

          Section 7.08. Conflicting interest of Trustee.
                        -------------------------------

          (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section 7.08, then, within 90 days after ascertaining that it
has such conflicting interest, and if the default (as defined in Section
7.08(c)) to which such conflicting interest relates has not been cured or duly
waived or otherwise eliminated before the end of such 90-day period, the Trustee
shall either eliminate such conflicting interest or, except as otherwise
provided in this Section 7.08, resign in the manner and with the effect
specified in Section 7.10, and the Company shall take prompt steps to have a
successor appointed in the manner provided in Section 7.10.

          (b) In the event that the Trustee shall fail to comply with the
provisions of Section 7.08(a), the Trustee shall, within ten days after the
expiration of such 90-day period, transmit notice of such failure to the
noteholders in the manner and to the extent provided in Section 5.04(c) with
respect to reports pursuant to Section 5.04(a).

                                      -73-



          (c) For the purposes of this Section 7.08, the Trustee shall be deemed
to have a conflicting interest if the Notes are in default (defined as the
occurrence of any event specified in Section 6.01, but exclusive of any period
of grace or requirement of notice) and

          (1) the Trustee is trustee under another indenture under which any
other securities, or certificates of interest or participation in any other
securities, of the Company are outstanding, unless such other indenture is a
collateral trust indenture under which the only collateral consists of Notes
issued under this Indenture, provided that there shall be excluded from the
operation of this paragraph any indenture or indentures under which other
securities, or certificates of interest or participation in other securities, of
the Company are outstanding if (i) this Indenture and such other indenture or
indentures are wholly unsecured and such other indenture or indentures are
hereafter qualified under the Trust Indenture Act of 1939, unless the Commission
shall have found and declared by order pursuant to Subsection (b) of Section 305
or Subsection (c) of Section 307 of the Trust Indenture Act of 1939 that
differences exist between the provisions of this Indenture and the provisions of
such other indenture or indentures which are so likely to involve a material
conflict of interest as to make it necessary in the public interest or for the
protection of investors to disqualify the Trustee from acting as such under this
Indenture and such other indenture or indentures, or (ii) the Company shall have
sustained the burden of proving, on application to the Commission and after
opportunity for hearing thereon, that the trusteeship under this Indenture and
such other indenture is not so likely to involve a material conflict of interest
as to make it necessary in the public interest or for the protection of
investors to disqualify the Trustee from acting as such under one of such
indentures;

          (2) the Trustee or any of its directors or executive officers is an
underwriter for the Company;

          (3) the Trustee directly or indirectly controls or is directly or
indirectly controlled by or is under direct or indirect common control with an
underwriter for the Company;

          (4) the Trustee or any of its directors or executive officers is a
director, officer, partner, employee, appointee, or representative of the
Company, or of an underwriter (other than the Trustee itself) for the Company
who is currently engaged in the business of underwriting, except that (A) one
individual may be a director and/or an executive officer of the Trustee and a
director and/or an executive officer of the Company, but may not be at the same
time an executive officer of both the Trustee and the Company; (B) if and so
long as the number of directors of the Trustee in office is more than nine, one
additional individual may be a director and/or an executive officer of the
Trustee and a director of the Company; and (C) the Trustee may be designated by
the Company or by any underwriter for the Company to act in the capacity of
transfer agent, registrar, custodian, paying agent, fiscal agent, escrow agent,
or depositary, or in any other similar capacity, or, subject to the provisions
of paragraph (1) of this subsection (c), to act as trustee whether under an
indenture or otherwise;

          (5) ten percent or more of the voting securities of the Trustee is
beneficially owned either by the Company or by any director, partner, or
executive officer thereof, or 20 percent or more of such voting securities is
beneficially owned, collectively, by any two or more of such persons; or ten
percent or more of the voting securities of the Trustee is beneficially owned
either by an underwriter for the Company or by any director, partner, or
executive officer thereof, or is beneficially owned, collectively, by any two or
more such persons;

          (6) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default, (A) five percent or more of the
voting securities, or ten percent or more 

                                      -74-



of any other class of security, of the Company, not including the Notes issued
under this Indenture and securities issued under any other indenture under which
the Trustee is also trustee, or (B) ten percent or more of any class of security
of an underwriter for the Company;

          (7) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default (as defined hereinafter), five
percent or more of the voting securities of any person who, to the knowledge of
the Trustee, owns ten percent or more of the voting securities of, or controls
directly or indirectly or is under direct or indirect common control with, the
Company;

          (8) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation that is in default, ten percent or more of any class
of security of any person who, to the knowledge of the Trustee, owns 50 percent
or more of the voting securities of the Company;

          (9) the Trustee owns on the date of default upon the Notes (defined as
the occurrence of any event specified in Section 6.01, but exclusive of any
period of grace or requirement of notice) or any anniversary of such default
while such default upon the Notes remains outstanding, in the capacity of
executor, administrator, testamentary or inter vivos trustee, guardian,
committee or conservator, or in any other similar capacity, an aggregate of 25
percent or more of the voting securities, or of any class of security, of any
person, the beneficial ownership of a specified percentage of which would have
constituted a conflicting interest under paragraph (6), (7), or (8) of this
subsection (c). As to any such securities of which the Trustee acquired
ownership through becoming executor, administrator, or testamentary trustee of
an estate which included them, the provisions of the preceding sentence shall
not apply for a period of two years from the date of such acquisition to the
extent that such securities included in such estate do not exceed 25 percent of
such voting securities or 25 percent of any such class of security. Promptly
after the dates of any such default upon the Notes and annually in each
succeeding year that the Notes remain in default, the Trustee shall make a check
of its holdings of such securities in any of the above-mentioned capacities as
of such dates. If the Company fails to make payment in full of principal of, or
premium, if any, Change of Control Purchase Price, Asset Sale Purchase Price or
interest on, any of the Notes when and as the same becomes due and payable and
such failure continues for 30 days thereafter, the Trustee shall make a prompt
check of its holdings of such securities in any of the above-mentioned
capacities as of the date of the expiration of such 30-day period, and after
such date, notwithstanding the foregoing provisions of this paragraph (9), all
such securities so held by the Trustee, with sole or joint control over such
securities vested in it, shall, but only so long as such failure shall continue,
be considered as though beneficially owned by the Trustee for the purposes of
paragraphs (6), (7) and (8) of this subsection (c); or

          (10) except under the circumstances described in paragraphs (1), (3),
(4), (5) or (6) of Section 311(b) of the Trust Indenture Act of 1939, the
Trustee shall become a creditor of the Company.

          The specifications of percentages in paragraphs (5) to (9), inclusive,
of this subsection (c) shall not be construed as indicating that the ownership
of such percentages of the securities of a person is or is not necessary or
sufficient to constitute direct or indirect control for the purpose of paragraph
(3) or (7) of this subsection (c).

          For the purposes of paragraphs (6), (7), (8) and (9) of this
subsection (c) only, (A) the terms "security" and "securities" shall include
only such securities as are generally known as corporate securities, but shall
not include any note or other evidence of indebtedness issued to evidence an
obligation to repay moneys lent to a person by one or more banks, trust
companies or banking firms, or any 

                                      -75-



certificate of interest or participation in any such note or evidence of
indebtedness; (B) an obligation shall be deemed to be "in default" when a
default in payment of principal shall have continued for 30 days or more and
shall not have been cured; and (C) the Trustee shall not be deemed to be the
owner or holder of (i) any security that it holds as collateral security (as
trustee or otherwise) for an obligation which is not in default as defined in
clause (B) above, or (ii), any security that it holds as collateral security
under this Indenture, irrespective of any default hereunder, or (iii) any
security that it holds as agent for collection, or as custodian, escrow agent,
or depositary, or in any similar representative capacity.

          Except as above provided, the word "security" or "securities" as used
in this Indenture, shall mean any note, stock, treasury stock, bond, note,
evidence of indebtedness, certificate of interest or participation in any
profit-sharing agreement, collateral-trust certificate, preorganization
certificate or subscription, transferable share, investment contract,
voting-trust certificate, certificate of deposit for a security, fractional
undivided interest in oil, gas, or other mineral rights, or, in general, any
interest or instrument commonly known as a "security," or any certificate of
interest or participation in, temporary or interim certificate for, receipt for,
guarantee of, or warrant or right to subscribe to or purchase, any of the
foregoing.

          Except in the case of a default in the payment of the principal of or
interest on the Notes, the Trustee shall not be required to resign as provided
by this Section 7.08 if the Trustee shall have sustained the burden of proving,
on application to the Commission and after opportunity for hearing thereon, that
(i) the default under this Indenture may be cured or waived during a reasonable
period and under the procedures described in such application, and (ii) a stay
of the Trustee's duty to resign will not be inconsistent with the interests of
holders of the Notes. The filing of such an application shall automatically stay
the performance of the duty to resign until the Commission orders otherwise.

          Any resignation of the Trustee shall become effective only upon the
appointment of a successor trustee and such successor's acceptance of such an
appointment.

          (d) For the purposes of this Section 7.08:

          (1) The term "underwriter" when used with reference to the Company
shall mean every person, who, within one year prior to the time as of which the
determination is made, has purchased from the Company with a view to, or has
offered or sold for the Company in connection with, the distribution of any
security of the Company outstanding at such time, or has participated or has had
a direct or indirect participation in any such undertaking, or has participated
or has had a participation in the direct or indirect underwriting of any such
undertaking, but such term shall not include a person whose interest was limited
to a commission from an underwriter or dealer not in excess of the usual and
customary distributors' or sellers' commission.

          (2) The term "director" shall mean any director of a corporation or
any individual performing similar functions with respect to any organization,
whether incorporated or unincorporated.

          (3) The term "person" shall mean an individual, a corporation, a
partnership, an association, a joint-stock company, a trust, an unincorporated
organization, or a government or political subdivision thereof. As used in this
paragraph, the term "trust" shall include only a trust where the interest or
interests of the beneficiary or beneficiaries are evidenced by a security.

                                      -76-



          (4) The term "voting security" shall mean any security presently
entitling the owner or holder thereof to vote in the direction or management of
the affairs of a person, or any security issued under or pursuant to any trust,
agreement or arrangement whereby a trustee or trustees or agent or agents for
the owner or holder of such security are presently entitled to vote in the
direction or management of the affairs of a person.

          (5) The term "Company" shall mean any obligor upon the Notes.

          (6) The term "executive officer" shall mean the president, every
vice-president, every trust officer, the cashier, the secretary, and the
treasurer of a corporation, and any individual customarily performing similar
functions with respect to any organization whether incorporated or
unincorporated, but shall not include the chairman of the board of directors.

     The percentages of voting securities and other securities specified in this
     Section 7.08 shall be calculated in accordance with the following
     provisions:

          (A) A specified percentage of the voting securities of the Trustee,
     the Company or any other person referred to in this Section 7.08 (each of
     whom is referred to as a "person" in this paragraph) means such amount of
     the outstanding voting securities of such person as entitles the holder or
     holders thereof to cast such specified percentage of the aggregate votes
     which the holders of all the outstanding voting securities of such person
     are entitled to cast in the direction or management of the affairs of such
     person.

          (B) A specified percentage of a class of securities of a person means
     such percentage of the aggregate amount of securities of the class
     outstanding.

          (C) The term "amount," when used in regard to securities, means the
     principal amount if relating to evidences of indebtedness, the number of
     shares if relating to capital shares, and the number of units if relating
     to any other kind of security.

          (D) The term "outstanding" means issued and not held by or for the
     account of the issuer. The following securities shall not be deemed
     outstanding within the meaning of this definition:

               (i) securities of an issuer held in a sinking fund relating to
          securities of the issuer of the same class;

               (ii) securities of an issuer held in a sinking fund relating to
          another class of securities of the issuer, if the obligation evidenced
          by such other class of securities is not in default as to principal or
          interest or otherwise;

               (iii) securities pledged by the issuer thereof as security for an
          obligation of the issuer not in default as to principal or interest or
          otherwise; and

               (iv) securities held in escrow if placed in escrow by the issuer
          thereof; 

     provided, however, that any voting securities of an issuer shall be deemed
     outstanding if any person other than the issuer is entitled to exercise the
     voting rights thereof.

                                      -77-



          (E) A security shall be deemed to be of the same class as another
     security if both securities confer upon the holder or holders thereof
     substantially the same rights and privileges; provided, however, that, in
     the case of secured evidences of indebtedness, all of which are issued
     under a single indenture, differences in the interest rates or maturity
     dates of various series thereof shall not be deemed sufficient to
     constitute such series different classes; and provided, further, that, in
     the case of unsecured evidences of indebtedness, differences in the
     interest rates or maturity dates thereof shall not be deemed sufficient to
     constitute them securities of different classes, whether or not they are
     issued under a single indenture.

          Section 7.09. Requirements for eligibility of Trustee.
                        ---------------------------------------

          The Trustee hereunder shall at all times be a corporation organized
and doing business under the laws of the United States or any State or territory
thereof or of the District of Columbia or a corporation or other person
permitted to act as the Trustee by the Commission (pursuant to the requirements
of Section 310(a)(1) of the Trust Indenture Act of 1939), authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $10,000,000, and subject to supervision or examination by Federal,
State, Territorial, or District of Columbia authority. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 7.09, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. The Trustee shall not be an
obligor upon the Notes or a Person directly or indirectly controlling,
controlled by, or under common control with any such obligor. In addition, the
Trustee shall at all times be approved to serve as transfer agent and registrar
by any securities exchange on which the Notes are listed or admitted for
trading. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.09, the Trustee shall resign
immediately in the manner and with the effect specified in Section 7.10.

          Section 7.10. Resignation or removal of Trustee.
                        ---------------------------------

          (a) The Trustee, or any trustee hereafter appointed, may at any time
resign by giving written notice of such resignation to the Company and to the
noteholders, such notice to the noteholders to be given by mailing (by
first-class mail) the notice to their addresses as they shall appear on the
registry books of the Company within 30 days after such notice is given to the
Company. Upon receiving such notice of resignation and evidence satisfactory to
it of such mailing, the Company shall promptly appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors of
the Company, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If no successor trustee shall
have been so appointed and have accepted appointment within 30 days after the
mailing of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee, or
any noteholder who has been a bona fide holder of a Note or Notes for at least
six months may, subject to the provisions of Section 6.08, on behalf of himself
and all others similarly situated, petition any such court for the appointment
of a successor trustee. Such court may thereupon, after such notice, if any, as
it may deem proper and prescribe, appoint a successor trustee.

          (b) In case at any time any of the following shall occur:

          (1) the Trustee shall fail to comply with the provisions of Section
7.08(a) after written request therefor by the Company or by any noteholder who
has been a bona fide holder of a Note or Notes for at least six months, or

                                      -78-



          (2) the Trustee shall cease to be eligible in accordance with the
provisions of Section 7.09 and shall fail to resign after written request
therefor by the Company or by any such noteholder, or

          (3) the Trustee shall become incapable of acting, or shall be adjudged
a bankrupt or insolvent, or a receiver of the Trustee or of its property shall
be appointed, or any public officer shall take charge or control of the Trustee
or of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, 

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors of the Company, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 6.08, any noteholder who has been a bona
fide holder of a Note or Notes for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor trustee. Such
court may thereupon, after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

          (c) Any resignation or removal of the Trustee and appointment of any
successor trustee pursuant to any of the provisions of this Section 7.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 7.11.

          Section 7.11. Acceptance by successor to Trustee; notice of succession
                        --------------------------------------------------------
of a Trustee.
- ------------

          Any successor trustee appointed as provided in Section 7.10 shall
execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee
herein; but, nevertheless, on the written request of the Company or of the
successor trustee, the trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of Section 7.06, execute and deliver an
instrument transferring to such successor trustee all the rights and powers of
the trustee so ceasing to act. Upon request of any such successor trustee, the
Company shall execute any and all instruments in writing for more fully and
certainly vesting in and confirming to such successor trustee of such rights and
powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all
property or funds held or collected by such trustee to secure any amounts then
due it pursuant to the provisions of Section 7.06.

          No successor trustee shall accept appointment as provided in this
Section 7.11 unless, at the time of such acceptance, such successor trustee
shall be qualified under the provisions of Section 7.08 and eligible under the
provisions of Section 7.09. Upon acceptance of appointment by a successor
trustee as provided in this Section 7.11, the Company shall mail to the
noteholders by first-class mail notice thereof. If the Company fails to mail
such notice within 30 days after acceptance of appointment by the successor
trustee, the successor trustee shall, in its discretion, cause such notice to be
mailed at the expense of the Company.

                                      -79-



          Section 7.12. Successor to Trustee by merger, consolidation or
                        ------------------------------------------------
succession to business; notice by Trustee of change in its location.
- -------------------------------------------------------------------

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger
or conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding, provided such corporation shall be
qualified under the provisions of Section 7.08 and eligible under the provisions
of Section 7.09.

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

          The Trustee will give the Company prompt notice of any change in the
location of the Trustee's principal office.

          Section 7.13. Limitations on rights of Trustee as a creditor.
                        ----------------------------------------------

          (a) Subject to the provisions of Section 7.13(b), if the Trustee shall
be or shall become a creditor, directly or indirectly, secured or unsecured, of
the Company within three months prior to a default, as defined in Section
7.13(c), or subsequent to such a default, then, unless and until such default
shall be cured or waived, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the holders of the Notes,
and the holders of other indenture securities (as defined in Section 7.13(c))

          (1) an amount equal to any and all reductions in the amount due and
owing upon any claim as such creditor in respect of principal or interest,
effected after the beginning of such three months' period, and valid as against
the Company and its other creditors, except any such reduction resulting from
the receipt or disposition of any property described in paragraph (2) of this
subsection, or from the exercise of any right of set-off which the Trustee could
have exercised if a petition in bankruptcy had been filed by or against the
Company upon the date of such default; and

          (2) all property received by the Trustee in respect of any claims as
such creditor, either as security therefor, or in satisfaction or composition
thereof, or otherwise, after the beginning of such three months' period, or an
amount equal to the proceeds of any such property if disposed of, subject,
however, to the rights, if any, of the Company and its other creditors in such
property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee 

                                      -80-



          (A) to retain for its own account (i) payments made on account of any
     such claim by any person (other than the Company) who is liable thereon,
     and (ii) the proceeds of the bona fide sale of any such claim by the
     Trustee to a third person, and (iii) distributions made in cash,
     securities, or other property in respect of claims filed against the
     Company in bankruptcy or receivership or in proceedings for reorganization
     pursuant to any applicable bankruptcy, insolvency or similar law;

          (B) to realize, for its own account, upon any property held by it as
     security for any such claim, if such property was so held prior to the
     beginning of such three months' period;

          (C) to realize, for its own account, but only to the extent of the
     claim hereinafter mentioned, upon any property held by it as security for
     any such claim, if such claim was created after the beginning of such three
     months' period and such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee shall sustain
     the burden of proving that at the time such property was so received the
     Trustee had no reasonable cause to believe that a default, as defined in
     Section 7.13(c), would occur within three months; or

          (D) to receive payment on any claim referred to in paragraph (B) or
     (C), against the release of any property held as security for such claim as
     provided in such paragraph (B) or (C), as the case may be, to the extent of
     the fair value of such property.

          For the purposes of paragraphs (B), (C) and (D) above, property
substituted after the beginning of such three months' period for property held
as security at the time of such substitution shall, to the extent of the fair
value of the property released, have the same status as the property released,
and to the extent that any claim referred to in any of such paragraphs is
created in renewal of or in substitution for or for the purpose of repaying or
refunding any preexisting claim of the Trustee as such creditor, such claim
shall have the same status as such preexisting claim.

          If the Trustee shall be required to account, the funds and property
held in such special account and the proceeds thereof shall be apportioned
between the Trustee, the noteholders, and the holders of other indenture
securities in such manner that the Trustee, the noteholders and the holders of
other indenture securities realize, as a result of payments from such special
account and payments of dividends on claims filed against the Company in
bankruptcy or receivership or in proceedings for reorganization pursuant to
applicable law, the same percentage of their respective claims, figured before
crediting to the claim of the Trustee anything on account of receipt by it from
the Company of the funds and property in such special account and before
crediting to the respective claims of the Trustee, the noteholders, and the
holders of other indenture securities dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to applicable law, but after crediting thereon receipts on account of
the indebtedness represented by their respective claims from all sources other
than from such dividends and from the funds and property so held in such special
account. As used in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such claim in
bankruptcy or receivership or in proceedings for reorganization pursuant to
applicable law, whether such distribution is made in cash, securities, or other
property, but shall not include any such distribution with respect to the
secured portion, if any, of such claim. The court in which such bankruptcy,
receivership or proceeding for reorganization is pending shall have jurisdiction
(i) to apportion between the Trustee, the noteholders, and the holders of other
indenture securities, in accordance with the provisions of this paragraph, the
funds and property held in such special account and the proceeds thereof, or
(ii) in lieu of such apportionment, in whole or in part, to give to the
provisions of this paragraph due consideration in determining the fairness of
the distributions to be made to the 

                                      -81-



Trustee, the noteholders and the holders of other indenture securities with
respect to their respective claims, in which event it shall not be necessary to
liquidate or to appraise the value of any securities or other property held in
such special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claims, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

          Any trustee who has resigned or been removed after the beginning of
such three months' period shall be subject to the provisions of this subsection
(a) as though such resignation or removal had not occurred. If any trustee has
resigned or been removed prior to the beginning of such three months' period, it
shall be subject to the provisions of this subsection (a) if and only if the
following conditions exist:

          (i) the receipt of property or reduction of claim which would have
     given rise to the obligation to account, if such trustee had continued as
     trustee, occurred after the beginning of such three months' period; and

          (ii) such receipt of property or reduction of claim occurred within
     three months after such resignation or removal.

          (b) There shall be excluded from the operation of Section 8.13(a) a
creditor relationship arising from

          (1) the ownership or acquisition of securities issued under any
indenture, or any security or securities having a maturity of one year or more
at the time of acquisition by the Trustee;

          (2) advances authorized by a receivership or bankruptcy court of
competent jurisdiction, or by this Indenture, for the purpose of preserving any
property which shall at any time be subject to the lien of this Indenture or of
discharging tax liens or other prior liens or encumbrances thereon, if notice of
such advance and of the circumstances surrounding the making thereof is given to
the noteholders at the time and in the manner provided in Section 5.04(c) with
respect to reports pursuant to Section 5.04(a);

          (3) disbursements made in the ordinary course of business in the
capacity of trustee under an indenture, transfer agent, registrar, custodian,
paying agent, fiscal agent or depositary, or other similar capacity;

          (4) an indebtedness created as a result of services rendered or
premises rented; or an indebtedness created as a result of goods or securities
sold in a cash transaction as defined in Section 7.13(c);

          (5) the ownership of stock or of other securities of a corporation
organized under the provisions of Section 25(a) of the Federal Reserve Act, as
amended, that is directly or indirectly a creditor of the Company; or

          (6) the acquisition, ownership, acceptance or negotiation of any
drafts, bills of exchange, acceptances or obligations which fall within the
classification of self-liquidating paper as defined in Section 7.13(c).

          (c) As used in this Section 7.13:

                                      -82-



          (1) the term "default" shall mean any failure to make payment in full
of the principal of, or premium, if any, Change of Control Purchase Price, Asset
Sale Purchase Price or interest on, any of the Notes or upon the other indenture
securities when and as any such amounts become due and payable.

          (2) the term "other indenture securities" shall mean securities upon
which the Company is an obligor (as defined in the Trust Indenture Act of 1939)
outstanding under any other indenture (A) under which the Trustee is also
trustee, (B) which contains special account provisions substantially similar to
the provisions of Section 7.13(a), and (C) under which a default exists at the
time of the apportionment of the funds and property held in the special account
thereunder.

          (3) the term "cash transaction" shall mean any transaction in which
full payment for goods or securities sold is made within seven days after
delivery of the goods or securities in currency or in checks or other orders
drawn upon banks or bankers and payable upon demand.

          (4) the term "self-liquidating paper" shall mean any draft, bill of
exchange, acceptance or obligation that is made, drawn, negotiated or incurred
by the Company for the purpose of financing the purchase, processing,
manufacture, shipment, storage or sale of goods, wares or merchandise and which
is secured by documents evidencing title to, possession of, or a lien upon, the
goods, wares or merchandise or the receivables or proceeds arising from the sale
of the goods, wares or merchandise previously constituting the security,
provided the security is received by the Trustee simultaneously with the
creation of the creditor relationship with the Company arising from the making,
drawing, negotiating or incurring of the draft, bill of exchange, acceptance or
obligation.

          (5) the term "Company" shall mean any obligor upon the Notes.

                                  ARTICLE EIGHT
                           CONCERNING THE NOTEHOLDERS

          Section 8.01. Evidence of action by noteholders.
                        ---------------------------------

          Whenever in this Indenture it is provided that the holders of a
specified percentage in aggregate principal amount of the Notes may take any
action (including the making of any demand or request, the giving of any notice,
consent, or waiver or the taking of any other action), the fact that the holders
of such specified percentage, determined as of the time such action was taken
or, if a record date was set with respect thereto pursuant to Section 8.05, as
of the close of business on such record date, have joined therein may be
evidenced (a) by any instrument or any number of instruments of similar tenor
executed by noteholders in person or by agent or proxy appointed in writing, or
(b) by the record of the holders of Notes voting in favor thereof at any meeting
of noteholders duly called and held in accordance with the provisions of Article
Nine, or (c) by a combination of such instrument or instruments and any such
record of such a meeting of noteholders.

          Section 8.02. Proof of execution of instruments and of holding of
                        ---------------------------------------------------
Notes.
- -----

          Subject to the provisions of Sections 7.01, 7.02 and 9.05, proof of
the execution of any instrument by a noteholder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee. The ownership of Notes shall be proved by the register of such
Notes, or by a certificate of the registrar thereof. The Trustee may accept such
other proof or require such additional 

                                      -83-



proof of any matter referred to in this Section 8.02 as it shall deem
reasonable. The record of any noteholders' meeting shall be proved in the manner
provided in Section 9.06.

          Section 8.03. Who may be deemed owners of Notes.
                        ---------------------------------

          Prior to due presentation for registration of transfer, the Company,
the Trustee, any paying agent and any Note registrar may deem and treat the
Person in whose name any Note shall be registered upon the books of the Company
as the absolute owner of such Note (whether or not such Note shall be overdue
and notwithstanding any notation of ownership or other writing thereon) for the
purposes of receiving payment of or on account of the principal of, and premium,
if any, Change of Control Purchase Price, Asset Sale Purchase Price and interest
on, such Note and for all other purposes; and neither the Company nor the
Trustee nor any paying agent nor any Note registrar shall be affected by any
notice to the contrary. All such payments so made to, or upon the order of, any
such holder shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for moneys payable upon any
such Note.

          Section 8.04. Notes owned by Company or controlled by controlling
                        ---------------------------------------------------
Persons disregarded for certain purposes.
- ----------------------------------------

          In determining whether the holders of the requisite aggregate
principal amount of Notes have concurred in any demand, direction, request,
notice, consent, waiver or other action under this Indenture, Notes that are
owned by the Company or any other obligor on the Notes or by any Person directly
or indirectly controlling or controlled by or under direct or indirect common
control with the Company or any other obligor on the Notes shall be disregarded
and deemed not to be outstanding for the purpose of any such determination,
provided that for the purposes of determining whether the Trustee shall be
protected in relying on any such demand, direction, request, notice, consent or
waiver, only Notes that the Trustee knows are so owned shall be so disregarded.
Notes so owned that have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 8.04, if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right to vote such
Notes and that the pledgee is not a Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
such other obligor. In case of a dispute as to such right, any decision by the
Trustee taken upon the advice of counsel shall be full protection to the
Trustee.

          Section 8.05. Record date for action by noteholders.
                        -------------------------------------

          Whenever in this Indenture it is provided that holders of a specified
percentage in aggregate principal amount of the Notes may take any action
(including the making of any demand or request, the giving of any direction,
notice, consent or waiver or the taking of any other action), other than any
action taken at a meeting of noteholders called pursuant to Article Nine, the
Company, pursuant to a resolution of its Board of Directors, or the holders of
at least 25% in aggregate principal amount of the Notes then outstanding, may
request the Trustee to fix a record date for determining noteholders entitled to
notice of and to take any such action. In case the Company or the holders of
Notes in the amount above specified shall desire to request noteholders to take
any such action and shall request the Trustee to fix a record date with respect
thereto by written notice setting forth in reasonable detail the noteholder
action to be requested, the Trustee shall promptly (but in any event within five
days of receipt of such request) fix a record date that shall be a Business Day
not less than 15 nor more than 20 days after the date on which the Trustee
receives such request. If the Trustee shall fail to fix a record date as
hereinabove provided, then the Company or the holders of Notes in the amount
above specified may fix the same by mailing notice thereof (the record date so
fixed to be a Business Day not less than 15 nor 

                                      -84-



more than 20 days after the date on which such written notice shall be given) to
the Trustee. If a record date is fixed according to this Section 8.05, only
Persons shown as noteholders on the registry books of the Company at the close
of business on the record date so fixed shall be entitled to take the requested
action and the taking of any such action by the holders at the close of business
on the record date of the required percentage of the aggregate principal amount
of the Notes shall be binding on all noteholders, provided that the taking of
the requested action by the holders at the closeof business on the record date
of the percentage in aggregate principal amount of the Notes specified in this
Indenture in connection with such action shall have been evidenced to the
Trustee, as provided in Section 8.01, not later than 180 days after such record
date.

          Section 8.06. Instruments executed by noteholders bind future holders.
                        -------------------------------------------------------

          At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any action by the holders of the
percentage in aggregate principal amount of the Notes specified in this
Indenture in connection with such action, any holder of a Note which is shown by
the evidence to be included in the Notes the holders of which have consented to
such action may, by filing written notice with the Trustee at its principal
office and upon proof of holding as provided in Section 8.02, revoke such action
so far as concerns such Note. Except as aforesaid any such action taken by the
holder of any Note and any direction, demand, request, waiver, consent, vote or
other action of the holder of any Note which by any provisions of this Indenture
is required or permitted to be given shall be conclusive and binding upon such
holder and upon all future holders and owners of such Note, and of any Note
issued in lieu thereof, irrespective of whether or not any notation in regard
thereto is made upon such Note. Any action taken by the holders of the
percentage in aggregate principal amount of the Notes specified in this
Indenture in connection with such action shall be conclusively binding upon the
holders of all the Notes.

                                  ARTICLE NINE

respect to which such record date was so fixed.

          In case at any time the Company, pursuant to a resolution of its Board
of Directors, or the holders of at least 25% in aggregate principal amount of

of proxies, and in regard to the appointment and duties of inspectors of votes,
the submission and examination of proxies, certificates and other evidence of
the right to vote, and such other matters concerning the conduct of the meeting
as it shall think fit. Except as otherwise permitted or required by any such
regulations, the holding of Notes shall be proved in the manner specified in
Section 8.02. The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by noteholders as provided in Section 9.03, in which case the
Company or the noteholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by a vote of the holders of a majority
in principal amount of the Notes represented at the meeting and entitled to
vote. Subject to the provisions of Section 8.04, at any meeting each noteholder
or proxy entitled to vote thereat shall be entitled to one vote for each $1,000
principal amount of Notes held or represented by him; provided, however, that no
vote shall be cast or 

                                      -86-



counted at any meeting in respect of any Note challenged as not outstanding and
ruled by the chairman of the meeting to be not outstanding. The chairman of the
meeting shall have no right to vote other than by virtue of Notes held by him or
instruments in writing as aforesaid duly designating him as the Person to vote
on behalf of other noteholders. Any meeting of noteholders duly called pursuant
to the provisions of Section 9.02 or 9.03 may be adjourned from time to time,
and the meeting may be held as so adjourned without further notice. At any
meeting of noteholders, the presence of Persons who held, or ho are acting as
proxy for Persons who held, an aggregate principal amount of Notes on the record
date for such meeting sufficient to take action on the business for the
transaction of which such meeting was called shall constitute a quorum, but, if
less than a quorum is present, the Persons holding or representing a majority in
aggregate principal amount of the Notes represented at the meeting may adjourn
such meeting with the same effect, for all intents and purposes, as though a
quorum had been present.

          Section 9.06. Manner of voting at meetings and record to be kept.
                        --------------------------------------------------

          The vote upon any resolution submitted to any meeting of noteholders
shall be by written ballots on each of which shall be subscribed the signature
of the noteholder or proxy casting such ballot, the principal amount and, if
practicable, the identifying number or numbers of the Notes held or represented
in respect of which such ballot is cast. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record in duplicate of the proceedings of each
meeting of noteholders shall be prepared by the secretary of the meeting and
there shall be attached to said record the original reports of the inspectors of
votes on any vote by ballot taken thereat and affidavits by one or more Persons
having knowledge of the facts setting forth a copy of the notice of the meeting
and showing that said notice was mailed as provided in Section 9.02. The record
shall show the aggregate principal amount and, if practicable, the identifying
numbers of the Notes voting in favor of or against any resolution. Each
counterpart of such record shall be signed and verified by the affidavits of the
permanent chairman and secretary of the meeting and one of the counterparts
shall be delivered to the Company and the other to the Trustee to be preserved
by the Trustee. Any counterpart record so signed and verified shall be
conclusive evidence of the matters therein stated and shall be the record
referred to in clause (b) of Section 8.01.

          Section 9.07. Exercise of rights of Trustee and noteholders not to be
                        -------------------------------------------------------
hindered or delayed.
- -------------------

          Nothing in this Article Nine shall be deemed or construed to authorize
or permit, by reason of any call of a meeting of noteholders or any rights
expressly or impliedly conferred hereunder to make such call, any hindrance or
delay in the exercise of any right or rights conferred upon or reserved to the
Trustee or to the noteholders under any of the provisions of this Indenture or
of the Notes.

entered into without consent of noteholders.
- -------------------------------------------

          The Company and its Subsidiaries, when authorized by Board Resolutions
of such Persons, and the Trustee may from time to time and at any time enter
into an indenture or indentures 

                                      -87-



supplemental hereto (which shall comply with the provisions of the Trust
Indenture Act of 1939 as then in effect) for one or more of the following
purposes:

          (a) to comply with Article Eleven and Sections 4.12 and 15.03;

          (b) to add to the covenants of the Company such further covenants,
restrictions or conditions as its Board of Directors shall consider to be for
the protection of the holders of Notes, and to make the occurrence, or the
occurrence and continuance, of a default in any of such additional covenants,
restrictions or conditions a default or an Event of Default permitting the
enforcement of all or any of the several remedies provided in this Indenture as
herein set forth; provided, however, that in respect of any such additional
covenant, restriction or condition such supplemental indenture may provide for a
particular period of grace after default (which period may be shorter or longer
than that allowed in the case of other defaults) or may provide for an immediate
enforcement upon such default or may limit the remedies available to the Trustee
upon such default;

          (c) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture, or to comply with any requirements of the Commission in order to
effect or maintain the qualification of this Indenture under the Trust Indenture
Act of 1939, or to make such other provisions in regard to matters or questions
arising under this Indenture or any supplemental indenture as shall not
adversely affect the rights of the holders of the Notes;

          (d) to provide for the issuance under this Indenture of Notes, whether
or not then outstanding, in coupon form (including Notes registrable as to
principal only) and to provide for exchangeability of such Notes with Notes
issued hereunder in fully registered form and to make all appropriate changes
for such purpose; and

          (e) to comply with the requirements of the National Association of
Securities Dealers, Inc. Automated Quotation System, the New York Stock Exchange
or any other national securities exchange on which the Notes may be issued,
quoted or admitted for trading, provided such changes do not adversely affect
the rights of any holder of Notes.

          The Trustee is hereby authorized to join with the Company and its
Subsidiaries in the execution and delivery of any such supplemental indenture,
to make any further appropriate agreement and stipulations which may be therein
contained and to accept the conveyance, transfer, mortgage, pledge or assignment
of any property thereunder, provided that if any such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, the Trustee may in its discretion, but shall not be obligated to,
enter into such supplemental indenture. Any supplemental indenture authorized by
the provisions of this Section 10.01 may be executed by the Company, its
Subsidiaries and the Trustee without the consent of the holders of any of the
Notes at the time outstanding, notwithstanding any of the provisions of Section
10.02.

          Section 10.02. Modification of Indenture with consent of holders of a
                         ------------------------------------------------------
majority in principal amount of Notes.
- -------------------------------------

          With the consent (evidenced as provided in Section 8.01) of the
holders of not less than a majority in aggregate principal amount of the Notes
at the time outstanding (determined as provided in Sections 8.04 and 8.05), or,
if a record date is set with respect to such consent in accordance with Section
8.05, as of the close of business on such record date, the Company and its
Subsidiaries, when authorized 

                                      -88-



by Board Resolutions of such Persons, and the Trustee may from time to time and
at any time enter into an indenture or indentures supplemental hereto (which
shall comply with the provisions of the Trust Indenture Act of 1939 as then in
effect) for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of any supplemental
indenture or of modifying in any manner the rights of the holders of the Notes;
provided, however, that without the consent of each holder of an outstanding
Note affected, no such supplemental indenture shall (i) extend the stated
maturity of any Note, reduce the rate at which interest accrues on any Note,
extend the time or alter the manner of payment of interest on any Note, reduce
the principal amount of any Note, alter the timing of or reduce any premium
payable upon the redemption of any Note, change the currency in which any
payments are made on or with respect to any Note, change the ranking or
seniority of any Note, or reduce the amount payable on any Note in the event of
acceleration or the amount of any Note payable in bankruptcy, or (ii) reduce the
aforesaid percentage of aggregate principal amount of Notes the consent of the
holders of which is required for any such supplemental indenture.

          Upon the request of the Company, accompanied by a copy of the Board
Resolutions authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of noteholders as
aforesaid, the Trustee shall join with the Company and its Subsidiaries in the
execution and delivery of such supplemental indenture, provided that if such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, the Trustee may in its discretion, but shall
not be obligated to, enter into such supplemental indenture. It shall not be
necessary for the consent of the noteholders under this Section 10.02 to approve
the particular form of any proposed supplemental indenture, but it shall be
sufficient if such consent shall approve the substance thereof. Promptly after
the execution and delivery by the Company, its Subsidiaries and the Trustee of
any supplemental indenture pursuant to the provisions of this Section 10.02, the
Company shall mail a notice to the noteholders, setting forth in general terms
the substance of such supplemental indenture. 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 supplemental indenture.

          Section 10.03. Effect of supplemental indentures.
                         ---------------------------------

          Upon the execution and delivery of any supplemental indenture pursuant
to the provisions of this Article Ten, this Indenture shall be and be deemed to
be modified and amended in accordance therewith and the respective rights,
limitation of rights, obligations, duties and immunities under this Indenture of
the Trustee, the Company, its Subsidiaries and the holders of Notes shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

          Section 10.04. Notes may bear notation of changes by supplemental
                         --------------------------------------------------
indentures.
- ----------

          Notes authenticated and delivered after the execution and delivery of
any supplemental indenture pursuant to the provisions of this Article Ten, or
after any action taken at a noteholders' meeting pursuant to Article Nine, may
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture or as to any action taken at any such meeting. If
the Company shall so determine, new Notes so modified as to conform, in the
opinion of the Trustee and the Company, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Company,
authenticated by the Trustee and delivered in exchange for the Notes then
outstanding upon surrender of such Notes. Failure to make the appropriate
notation or issue a new Note shall not affect the validity and effect of such
supplemental indenture or noteholders' meeting.

                                      -89-



          Section 10.05. Officers' Certificate and Opinion of Counsel.
                         --------------------------------------------

          The Trustee shall receive upon its request, and, subject to the
provisions of Sections 7.01 and 7.02, may rely as conclusive evidence upon, an
Officers' Certificate and an Opinion of Counsel that any such supplemental
indenture complies with the provisions of this Article Ten. In addition, the
Trustee shall receive upon its request an Opinion of Counsel that any such
supplemental indenture has been duly executed and delivered by all Persons party
thereto other than the Trustee.

          Section 10.06. Amendment of Security Agreements.
                         --------------------------------

          Without the consent of the Holders of not less than 66 2/3% in
aggregate principal amount of the Notes outstanding, the Collateral Agent and
the Company shall not amend the Security Agreements or release any of the
Collateral from a Lien or the Security Agreements (except in accordance with the
provisions thereof).

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

          (a) The Company shall not consolidate or merge with or into any other
entity or sell or convey (or permit any of its Subsidiaries to sell or convey)
all or substantially all of the Company's property (determined on a consolidated
basis for the Company and its Subsidiaries) to any other entity, whether in a
single transaction or a series of related transactions (the entity formed by or
surviving any such consolidation or merger, or to which such sale or conveyance
shall have been made, whether the Company or such other entity, being herein
called the "surviving corporation"), unless (i) immediately after giving effect
to such consolidation, merger, sale or conveyance, no Event of Default (or event
that, after notice or lapse of time, or both, would constitute an Event of
Default) shall exist, (ii) the surviving corporation shall be a corporation
organized under the laws of The United States of America or any State thereof,
(iii) immediately after giving effect to such consolidation, merger, sale or
conveyance, the surviving corporation could incur $1.00 of Indebtedness pursuant
to Section 4.10(a), (iv) the surviving corporation (if other than the Company)
shall expressly assume the due and punctual payment of the principal of, and
premium, if any, Change of Control Purchase Price, Asset Sale Purchase Price and
interest on, all of the Notes, according to their tenor, and the due and
punctual performance and observance of all the covenants and conditions of this
Indenture to be performed or observed by the Company, by supplemental indenture
complying with the requirements of Article Ten satisfactory in form to the
Trustee, (v) the surviving corporation (if other than the Company) shall

          (b) If at any time there be any consolidation or merger or sale or

          Section 11.02. Surviving corporation to be substituted.
                         ---------------------------------------

          In case of any such consolidation, merger, sale or conveyance and upon

of, and premium, if any, Change of Control Purchase Price, Asset Sale Purchase
Price and interest on, all of the Notes and the due and punctual performance and

to and be substituted for the Company, with the same effect as if it had been
named herein as the party of the first part, and the Company shall be relieved
of all its obligations and duties under this Indenture and the Notes. Such
surviving corporation thereupon may cause to be signed, and may issue either in
its own name or in the name of the Company, any or all of the Notes issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee; and, upon the order of such surviving corporation
(instead of the Company) and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver any Notes that previously shall have been signed and delivered by
the officers of the Company to the Trustee for authentication, and any Notes
that such surviving corporation thereafter shall cause to be signed and
delivered to the Trustee for that purpose. All the Notes so issued shall in all
respects have the same legal rank and benefit under this Indenture as the Notes
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Notes had been issued at the date of the execution hereof.
In case of any such consolidation, merger, sale or conveyance such changes in
phraseology and form (but not in substance) may be made in the Notes thereafter
to be issued as may be appropriate.

                         Defeasance.
                         ---------------------------------------------

          The Company, at its option at any time, may elect to have either
Section 12.02 or Section 12.03 applied to all outstanding Notes upon compliance
with the conditions set forth below in this Article Twelve.

          Section 12.02. Legal Defeasance and discharge.
                         ------------------------------

          Upon the Company's exercise under Section 12.01 of the option
applicable to this Section 12.02, the Company and its Subsidiaries shall be
deemed to have been discharged from their respective obligations with respect to
all outstanding Notes (including under the Guarantees) on the date the
conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). Such
Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Notes, and
this Indenture shall cease to be of further effect as to all outstanding Notes,
except as to (i) the rights of noteholders to receive payments in respect of the
principal of, and premium, if any, and interest on, the Notes when such payments
are due from the trust funds referred to in Section 12.04, (ii) the Company's
obligations with respect to the Notes under Sections 2.04, 2.05, 2.06, 2.07,

duties and immunities of the Trustee under this Indenture and the Company's
obligations in connection therewith (including without limitation those under

Article Twelve,

                                      -91-

the Company may exercise its option under this Section 12.02 notwithstanding the
prior exercise of its option under Section 12.03 with respect to the Notes.

          Section 12.03. Covenant Defeasance.
                         -------------------

          Upon the Company's exercise under Section 12.01 of the option
applicable to this Section 12.03, the Company shall be released from its
obligations under the covenants contained in Sections 3.05 through 3.09,
inclusive, Sections 4.08 through 4.11, inclusive, Sections 4.13 through 4.17,
inclusive, Article Eleven and Section 15.03 with respect to the outstanding
Notes on and after the date the conditions set forth below are satisfied
(hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed
not "outstanding" for the purposes of any direction, waiver, consent or
declaration or act of noteholders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder. For this purpose, Covenant Defeasance means
that, with respect to the outstanding Notes, the Company need not comply with
and shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such covenant to any other provision herein or in any other document, but,
except as specified above, the remainder of this Indenture and the Notes shall
be unaffected thereby. In addition, upon the Company's exercise under Section
12.01 of the option applicable to this Section 12.03, Sections 6.01(c), 6.01(d)
(as it relates to failure to observe or perform any of the covenants specified
above), 6.01(e) and 6.01(f) shall not constitute Events of Default.

          Section 12.04. Conditions to Legal Defeasance or Covenant Defeasance.
                         -----------------------------------------------------

          The following shall be the conditions to the application of either
Section 12.02 or Section 12.03 to the outstanding Notes:

               (i) the Company must irrevocably deposit with the Trustee, in
     trust for the benefit of the holders of the Notes, U.S. legal tender or
     Government Securities, or a combination thereof, in such amounts as will be
     sufficient, in the opinion of a nationally recognized firm of independent
     public accountants, to pay the principal of, and premium, if any, and
     interest on, such Notes on the stated maturity date or applicable
     redemption date, as the case may be, thereof, and the holders of the Notes
     must have a valid, perfected, exclusive security interest in such trust;

               (ii) in the case of an election under Section 12.02, the Company
     shall have delivered to the Trustee an Opinion of Counsel reasonably
     acceptable to Trustee confirming that (A) the Company has received from, or
     there has been published by, the Internal Revenue Service a ruling or (B)
     since the date hereof, there has been a change in the applicable federal
     income tax law, in either case to the effect that, and based thereon such
     Opinion of Counsel shall confirm that, the holders of the Notes will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such Legal Defeasance and will be subject to federal income tax on the
     same amounts, in the same manner and at the same times as would have been
     the case if such Legal Defeasance had not occurred;

               (iii) in the case of an election under Section 12.03, the Company
     shall have delivered to the Trustee an Opinion of Counsel reasonably
     acceptable to such Trustee confirming that the holders of the Notes will
     not recognize income, gain or loss for federal income tax purposes as a
     result of such Covenant Defeasance and will be subject to federal income
     tax in the

                                      -92-

     same amount, in the same manner and at the same times as would have been
     the case if such Covenant Defeasance had not occurred;

               (iv) no Event of Default (or event that, after notice or lapse of
     time, or both, would become an Event of Default) shall have occurred and be
     continuing on the date of such deposit or, in so far as Section 6.01(g) or
     6.01(h) is concerned, at any time between the date of such deposit and the
     91st day after the date of such deposit, and the Company shall have
     delivered to the Trustee an Opinion of Counsel, subject to such
     qualifications and exceptions as the Trustee deems appropriate, to the
     effect that, assuming no intervening bankruptcy of the Company between the
     date of such deposit and the 91st day following the date of such deposit
     and that no holder of the Notes is an insider of the Company, after the
     91st day following the date of such deposit the trust funds will not be
     subject to the effect of any applicable bankruptcy, insolvency,
     reorganization or similar laws affecting creditors rights generally;

               (v) such Legal Defeasance or Covenant Defeasance shall not result
     in a breach or violation of, or constitute a default under, this Indenture
     or any other material agreement or instrument to which the Company or any
     of its Subsidiaries is party or by which the Company or any of its
     Subsidiaries is bound;

               (vi) the Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit made by the Company pursuant to its
     election under Section 12.02 or 12.03 and was not made by the Company with
     the intent of preferring the holders of such Notes over other creditors of
     the Company or any of its Subsidiaries or with the intent of defeating,
     hindering, delaying or defrauding any other creditors of the Company or any
     of its Subsidiaries or others; and

               (vii) the Company shall have delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that the
     conditions precedent provided for in, in the case of the Officers'
     Certificate, clauses (i) through (vi) of this Section 12.04 and, in the
     case of the Opinion of Counsel, clauses (i) (with respect to the validity
     and perfection of the security interest) and (v) of this Section 12.04 have
     been complied with as contemplated by this Section 12.04.

          If the funds deposited with the Trustee to effect Legal Defeasance or
Covenant Defeasance are insufficient to pay the principal of, and premium, if
any, and interest on, the Notes when due or if the transfer of the funds to the
Trustee is avoided as a preferential transfer, fraudulent transfer or otherwise,
then the obligations of the Company and the Subsidiaries under this Indenture
will be revived and no such defeasance will be deemed to have occurred.

          Section 12.05. Application by Trustee of funds deposited for payment
                         of Notes.
                         -----------------------------------------------------

          All amounts deposited with the Trustee pursuant to Section 12.04 shall
be held in trust and applied by it to the payment, either directly or through
any paying agent (including the Company acting as its own paying agent), to the
holders of the particular Notes, for the payment or redemption of which such
moneys have been deposited with the Trustee, of all sums due and to become due
thereon for principal, premium, if any, and interest.

moneys then held by any paying agent under the provisions of this Indenture
shall, upon demand of the Company, be paid

                                      -93-

to the Trustee and thereupon such paying agent shall be released from all
further liability with respect to such moneys.

          Section 12.07. Repayment of moneys held by Trustee.
                         -----------------------------------

          The Trustee shall promptly pay to the Company upon written request any
excess money or securities held by it at any time, provided that the Trustee
shall in no event be required to deliver any excess cash or securities if an
Event of Default under Section 6.01(h) or 6.01(i) (or an event that after notice
or lapse of time, or both, would become an Event of Default) shall have occurred
during such period and be continuing. Any moneys deposited with the Trustee or
any paying agent for the payment of the principal of, or premium, if any, Change
of Control Purchase Price, Asset Sale Purchase Price or interest on, any Notes
and not applied but remaining unclaimed by the holders of Notes for two years
after the date upon which such payment shall have become due, shall be promptly
repaid (together with any interest earned thereon) to the Company by the Trustee
or by such paying agent; and thereupon the Trustee and such paying agent shall
be released from all further liability with respect to such moneys, and the
holder of any of the Notes entitled to receive such payment shall thereafter
look only to the Company for the payment thereof; provided, however, that the
Trustee or such paying agent, before being required to make any such repayment,
may, at the expense of the Company, mail to the holders of Notes at their last
known address or cause to be published once in a newspaper published in the
English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, City of New York, State of New York, a
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days after the date of such mailing or
publication, any unclaimed balance of such money then remaining will be paid to
the Company.

          Section 12.08. Reinstatement.
                         -------------

          If the Trustee is unable to apply any money or securities deposited by
the Company with the Trustee in accordance with Section 12.04 by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company and its Subsidiaries under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 12.04 until such time as the Trustee is permitted
to apply all such money or securities deposited by the Company with the Trustee
in accordance with Section 12.04; provided, however, that if the Company has
made any payment of principal of, or premium, if any, Change of Control Purchase
Price, Asset Sale Purchase Price or interest on, any Notes because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the holders of such Notes to receive such payment from the money or
securities deposited by the Company and held by the Trustee.

          If a notice or communication is mailed in the manner so provided
within the time prescribed, it is duly given, whether or not the addressee
receives it. Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event or action relating thereto, and such waiver shall be
equivalent of such notice. Waivers of notice by noteholders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity

similar activity, or any act of God or any other cause, it shall be impractical
to mail any notice as required by this Indenture, then any manner of giving such
notice as shall be made with the approval of the Trustee shall constitute
sufficient giving of notice hereunder.

than those provided for in Section 5.03(d)) or opinion provided for in this
Indenture and delivered to the Trustee with respect to compliance with a
condition or covenant provided for in this Indenture shall include

          (1) a statement that the person making such certificate or opinion has
     read such covenant or condition;

be based, insofar as it relates to legal matters, upon a certificate or opinion
of or representations by counsel, unless such officer knows that the certificate

knows that the certificate, statement or opinion or representations with respect
to the matters upon which his or her certificate, statements or opinion may be
based as aforesaid are erroneous.

of counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants unless such officer or counsel, as the case may be, knows that the
certificate or opinion or representations with respect to the accounting matters
upon which his certificate, statement or opinion may be based as aforesaid are

any, Change of Control Purchase Price, Asset Sale Purchase Price or interest on,
the Notes or the date fixed for redemption or purchase of any Note shall not be

and effect as if made on the date of payment or the date fixed for redemption or
purchase, and no interest shall accrue on or after such original date of payment
or such original date fixed for redemption or purchase.

                               GUARANTEE OF NOTES

          Section 15.01. Guarantee.
                         ---------

          Subject to the provisions of this Article Fifteen, each Subsidiary of
the Company, jointly and severally, hereby unconditionally guarantees to each
holder of a Note authenticated and delivered by the Trustee (i) the due and
punctual payment of the principal of, and premium, if any, Change of Control
Purchase Price, Asset Sale Purchase Price and interest on, such 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 on the overdue principal,
if any, of, and premium, Change of Control Purchase Price, Asset Sale Purchase
Price and interest, if any, on, such Note, to the extent lawful, and the due and
punctual performance of all other obligations of the Company to the holder of
such Note or the Trustee all in accordance with the terms of such Note and of
this Indenture, and (ii) in the case of any extension of time of payment or
renewal of such Note 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 Subsidiary of the Company hereby agrees 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 guarantor. Each Subsidiary of the Company hereby waives diligence,
presentment, 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, the
benefit of discussion, protest or notice with respect to any such Note or the
indebtedness evidenced thereby and all demands whatsoever, and covenants that
this Guarantee will not be discharged as to any such Note except by payment in
full of the principal thereof, and premium, if any, Change of Control Purchase
Price, Asset Sale Purchase Asset and interest thereon (and interest on the
overdue principal, if any, thereof, and premium, Change of Control Purchase
Price, Asset Sale Purchase Price and interest, if any, thereon, to the extent
lawful), or as provided in Sections 12.02 and 15.05. Notwithstanding the
foregoing, if the Trustee or any noteholder is required by any court or
otherwise to return to the Company, any of its Subsidiaries or any trustee,
liquidator or other similar official acting in relation to the Company or any of
its Subsidiaries any amount paid by any of them to the Trustee or said
noteholder in respect of any Note, this Guarantee, to the extent theretofore
discharged as to such Note (other than as provided in Section 15.05), shall be
reinstated in full force and effect.

          Each Subsidiary of the Company further agrees that, as between such
Subsidiary, on the one hand, and the holders of Notes and the Trustee, on the
other hand, (i) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six 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 Six, such obligations (whether or not due and payable) shall, subject to
the other provisions of this Article Fifteen, forthwith become due and payable
by such Subsidiary for the purpose of this Guarantee. Each Subsidiary of the
Company shall be subrogated to all rights of the holder of any Notes against the
Company or any other Subsidiary in respect of any amounts paid to the holder of
Notes by such Subsidiary pursuant to the provisions of this Guarantee; provided,
however, that such Subsidiary shall not be entitled to enforce, or to receive
any payments arising out of or based upon, such right of

                                      -99-

subrogation until the principal of, and premium, if any, Change of Control
Purchase Price, Asset Sale Purchase Price and interest on, all Notes shall have
been paid in full.

          Section 15.02. Limitation of Subsidiary's Liability.
                         ------------------------------------

          Each Subsidiary of the Company and, by its acceptance hereof, each
holder of a Note hereby confirms that it is the intention of all such parties
that the guarantee by such Subsidiary pursuant to its Guarantee not constitute a
fraudulent transfer or conveyance for purposes of the United States Bankruptcy
Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act
or any similar federal or state law. To effectuate the foregoing intention, the
holders of the Notes and each such Subsidiary hereby irrevocably agree that the
obligations of such Subsidiary under its Guarantee shall be limited to the
maximum amount as will, after giving effect to all other contingent and fixed
liabilities of such Subsidiary and after giving effect to any collections from
or payments made by or on behalf of any other Subsidiary of the Company in
respect of the obligations of such other Subsidiary under its Guarantee or
pursuant to any rights of contribution of such Subsidiary, result in the
obligations of such Subsidiary under its Guarantee not constituting such
fraudulent transfer or conveyance.

          Section 15.03. Subsidiaries may consolidate, etc., on certain terms.
                         ----------------------------------------------------

          (a) Except as set forth in Section 15.03(b), no Subsidiary of the
Company (other than a Subsidiary the Guarantee of which is to be released in
accordance with the terms of Section 15.05 in connection with any transaction
complying with Section 4.14) shall consolidate or merge with or into any other
entity, unless: (i) immediately after giving effect to such consolidation or
merger, no Event of Default (or event that, after notice or lapse of time, or
both, would constitute an Event of Default) shall exist, (ii) the surviving
corporation shall be a Subsidiary of the Company organized under the laws of the
United States of America or any State thereof, (iii) immediately after giving
effect to such consolidation or merger, the Company could Incur $1.00 of
Indebtedness pursuant to Section 4.10(a), (iv) the surviving corporation (if
other than such Subsidiary) shall expressly assume the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed by such Subsidiary (including without limitation the
obligations of such Subsidiary under its Guarantee) by supplemental indenture
complying with the requirements of Article Ten satisfactory in form to the
Trustee, executed and delivered to the Trustee, and (v) immediately after giving
effect to such consolidation or merger, the surviving corporation shall have a
Consolidated Net Worth equal to or greater than the Consolidated Net Worth of
such Subsidiary immediately prior to such transaction.

          If at any time there shall be any consolidation or merger to which
this Section 15.03(a) is applicable, then, in any such event, the surviving
corporation shall promptly deliver to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that such merger or consolidation, and any
supplemental indenture, if applicable, executed in connection therewith, comply
with this Section 15.03(a). In case of any such consolidation or merger and upon
the assumption by the surviving corporation (if other than such Subsidiary), in
the manner hereinabove provided, of the due and punctual performance of all the
covenants and conditions of this Indenture to be performed by such Subsidiary
(including without limitation the obligations of such Subsidiary under its
Guarantee), such surviving corporation shall succeed to and be substituted for
such Subsidiary, with the same effect as if it had been named herein as such
Subsidiary.

          (b) Notwithstanding Section 15.03(b), (i) a Wholly-Owned Subsidiary
may consolidate or merge with or into the Company, provided that the Company
shall be the surviving corporation, and

                                     -100-

(ii) a Wholly-Owned Subsidiary may consolidate or merge with or into any other
Wholly-Owned Subsidiary.

          Section 15.04. Application of certain terms and provisions to the
                         Subsidiaries.
                         --------------------------------------------------

          (a) For purposes of any provision of this Indenture that provides for
the delivery by any Subsidiary of the Company of an Officers' Certificate and/or
an Opinion of Counsel, the definitions of such terms in Section 1.01 shall apply
to such Subsidiary as if references therein to the Company were references to
such Subsidiary.

          (b) The Subsidiaries of the Company shall comply with all reporting
requirements of Section 5.03 as if references therein to the Company were
references to such Subsidiaries.

          (c) Any request, direction, order or demand which by any provision of
this Indenture is to be made by any Subsidiary of the Company shall be
