     if so, whether the Issuer will have the option to redeem such Securities
     rather than pay such additional amounts;

               (15)  if the Securities are to be issuable in definitive form
     (whether upon original issue or upon exchange of a temporary Security) only
     upon receipt of certain certificates or other documents or satisfaction of
     other conditions, the form and terms of such certificates, documents or
     conditions;

               (16)  if a person other than Wachovia Bank of Georgia, N.A. is to
     act as Trustee for the Securities, the name and location of the Corporate
     Trust Office of such Trustee;

               (17)  any trustees (other than the Trustee named herein),
     Depositaries, authenticating or paying agents, transfer agents or
     registrars or any other agents with respect to the Securities;

               (18)  any other events of default or covenants with respect to
     the Securities, whether or not such events of default or covenants are
     consistent with the events of default or covenants set forth herein;

               (19)  whether the Securities are to be listed on any stock
     exchange and, in such case, the name of the stock exchange; and

               (20)  any other terms (which terms shall not be inconsistent with
     the provisions of this Indenture).

          All Securities shall be substantially identical, except as to
denomination and except as may otherwise be provided by or pursuant to the Board
Resolution or Officer's Certificate referred to above or as set forth in any
indenture supplemental hereto.  All Securities need not be issued at the same
time and may be issued from time to time, consistent with the terms of this
Indenture, if so provided by or pursuant to such Board Resolution, such
Officer's Certificate or in any indenture supplemental hereto.  All Securities
governed by this Indenture and any indenture supplement hereto shall be
registered on the security register of the Issuer.

          Section 2.4  Authentication and Delivery of Securities.  The Issuer
                       -----------------------------------------             
may deliver Securities executed by the Issuer to the Trustee for authentication
together with the applicable documents referred to below in this Section, and
the Trustee shall thereupon authenticate and deliver such Securities to or upon
the order of the Issuer (contained in the Issuer Order referred to below in this
Section) or pursuant to such procedures acceptable

                                       11

 
to the Trustee and to such recipients as may be specified from time to time by
an Issuer Order.  The maturity date, original issue date, interest rate and any
other terms of the Securities shall be determined by or pursuant to such Issuer
Order and procedures.  If provided for in such procedures, such Issuer Order may
authorize authentication and delivery pursuant to written instructions from the
Issuer or its duly authorized agent.  In authenticating such Securities and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive (in the case of
subparagraphs 2, 3 and 4 below only at or before the time of the first request
of the Issuer to the Trustee to authenticate Securities) and (subject to Section
6.1) shall be fully protected in relying upon, unless and until such documents
have been superseded or revoked:

               (1)  an Issuer Order requesting such authentication and setting
     forth delivery instructions if the Securities are not to be delivered to
     the Issuer, provided that, with respect to Securities subject to a Periodic
     Offering, (a) such Issuer Order may be delivered by the Issuer to the
     Trustee prior to the delivery to the Trustee of such Securities for
     authentication and delivery, (b) the Trustee shall authenticate and deliver
     Securities for original issue from time to time, in an aggregate principal
     amount not exceeding the aggregate principal amount established for such
     Securities, pursuant to an Issuer Order or pursuant to procedures
     acceptable to the Trustee as may be specified from time to time by an
     Issuer Order, (c) the maturity date or dates, original issue date or dates,
     interest rate or rates and any other terms of Securities shall be
     determined by an Issuer Order or pursuant to such procedures and (d) if
     provided for in such procedures, such Issuer Order may authorize
     authentication and delivery pursuant to written instructions from the
     Issuer or its duly authorized agent or agents;

               (2)  any Board Resolution, Officer's Certificate and/or executed
     supplemental indenture referred to in Section 2.1 or 2.3 by or pursuant to
     which the forms and terms of the Securities were established;

               (3)  an Officer's Certificate setting forth the form or forms and
     terms of the Securities, stating that the form or forms and terms of the
     Securities have been established pursuant to Sections 2.1 and 2.3 and
     comply with this Indenture, and covering such other matters as the Trustee
     may reasonably request; and

                                       12

 
               (4) either an Opinion of Counsel, or a letter addressed to the
     Trustee permitting it to rely on an Opinion of Counsel, substantially to
     the effect that:

                    (a)  the forms of the Securities have been duly authorized
          and established in conformity with the provisions of this Indenture;

                    (b)  the terms of the Securities have been duly authorized
          and established in conformity with the provisions of this Indenture;

                    (c)  when the Securities have been executed by the Issuer
          and authenticated by the Trustee in accordance with the provisions of
          this Indenture and delivered to and duly paid for by the purchasers
          thereof, they will have been duly issued under this Indenture and will
          be valid and legally binding obligations of the Issuer, enforceable in
          accordance with their respective terms, and will be entitled to the
          benefits of this Indenture; and

                    (d)  the execution and delivery by the Issuer of, and the
          performance by the Issuer of its obligations under, the Securities
          will not contravene any provision of applicable law or the certificate
          of incorporation or by-laws of the Issuer or any agreement or other
          instrument binding upon the Issuer or any of its Subsidiaries that is
          material to the Issuer and its Subsidiaries, considered as one
          enterprise, or any judgment, order or decree of any governmental body,
          agency or court having jurisdiction over the Issuer or any Subsidiary,
          and no consent, approval or authorization of any governmental body or
          agency is required for the performance by the Issuer of its
          obligations under the Securities except such as are specified and have
          been obtained and such as may be required by the securities or blue
          sky laws of the various states in connection with the offer and sale
          of the Securities.

          In rendering such opinions, such counsel may qualify any opinions as
to enforceability by stating that such enforceability may be limited by
bankruptcy, insolvency, reorganization, liquidation, moratorium and other
similar laws affecting the rights and remedies of creditors and is subject to
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).  Such counsel may rely, as to
all matters governed by the laws of jurisdictions other than the Commonwealth of
Pennsylvania and the federal law of the United States, upon opinions of other

                                       13

 
counsel (copies of which shall be delivered to the Trustee), who shall be
counsel reasonably satisfactory to the Trustee, in which case the opinion shall
state that such counsel believes he and the Trustee are entitled so to rely.
Such counsel may also state, inter alia, that, insofar as such opinion involves
                             ----- ----                                        
factual matters, he has relied, to the extent he deems proper, upon certificates
of officers of the Issuer and its Subsidiaries and certificates of public
officials.

          The Trustee shall have the right to decline to authenticate and
deliver any Securities under this Section if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken by the Issuer or
if the Trustee in good faith by its board of directors or board of trustees,
executive committee, or a trust committee of directors or trustees or a
Responsible Officer shall determine that such action would expose the Trustee to
any liability or would affect the Trustee's own rights, duties or immunities
under the Securities, this Indenture or otherwise.

          If the Issuer shall establish pursuant to Section 2.3 that the
Securities are to be issued in the form of one or more Global Securities, then
the Issuer shall execute and the Trustee shall, in accordance with this Section
and the Issuer Order, authenticate and deliver one or more Global Securities
that (i) shall represent and shall be denominated in an amount equal to the
aggregate principal amount of all of the Securities issued and not yet
cancelled, (ii) shall be registered in the name of the Depositary for such
Global Security or Securities or the nominee of such Depositary, (iii) shall be
delivered by the Trustee to such Depositary or pursuant to such Depositary's
instructions and (iv) shall bear a legend substantially to the following effect:
"Unless and until it is exchanged in whole or in part for Securities in
definitive registered form in accordance with the provisions of the Indenture
and the terms of this Security, this Security may not be transferred except as a
whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary."

          Each Depositary designated pursuant to Section 2.3 must, at the time
of its designation and at all times while it serves as Depositary, be a clearing
agency registered under the Securities Exchange Act of 1934, and any other
applicable statute or regulation.

          Section 2.5  Execution of Securities.  The Securities shall be signed
                       -----------------------                                 
on behalf of the Issuer by any person who is at such time the chairman or vice
chairman of its Board of Directors or its president or any vice president or its
treasurer or its

                                       14

 
secretary, under its corporate seal which may, but need not, be attested.  Such
signature(s) may be the manual or facsimile signature(s) of the present or any
future such officer(s).  The seal of the Issuer may be in the form of a
facsimile thereof and may be impressed, affixed, imprinted or otherwise
reproduced on the Securities.  Typographical and other minor errors or defects
in any such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security that has been duly authenticated and
delivered by the Trustee.

          In case any officer of the Issuer who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by the Trustee or disposed of by the Issuer, such
Security nevertheless may be authenticated and delivered or disposed of as
though the person who signed such Security had not ceased to be such officer of
the Issuer; and any Security may be signed on behalf of the Issuer by such
person(s) as, at the actual date of the execution of such Security, shall be the
proper officer(s) of the Issuer, although at the date of the execution and
delivery of this Indenture any such person was not such an officer.

          Section 2.6  Certificate of Authentication.  Only such Securities as
                       -----------------------------                          
shall bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized officers at such time, shall be entitled to the benefits of this
Indenture or be valid or obligatory for any purpose.  The execution of such
certificate by the Trustee upon any Security executed by the Issuer shall be
conclusive evidence that the Security so authenticated has been duly
authenticated and delivered hereunder and that the Holder is entitled to the
benefits of this Indenture.

          Section 2.7  Denomination and Date of Securities; Payments of
                       ------------------------------------------------
Interest.  The Securities shall be issuable as Securities in denominations
- --------
established as contemplated by Section 2.3 or, if not so established, in
denominations of $1,000 and any integral multiple thereof.  The Securities shall
be numbered, lettered or otherwise distinguished in such manner or in accordance
with such plan as the officer(s) of the Issuer executing the same may determine
with the approval of the Trustee, as evidenced by the execution and
authentication thereof.

          Each Security shall be dated the date of its authentication.  The
Securities shall bear interest, if any, from the date, and such interest shall
be payable on the dates, established as contemplated by Section 2.3.

                                       15

 
          The person in whose name any Security is registered at the close of
business on any record date applicable thereto with respect to any interest
payment date shall be entitled to receive the interest, if any, payable on such
interest payment date notwithstanding any transfer or exchange of such Security
subsequent to the record date and prior to such interest payment date, except if
and to the extent the Issuer shall default in the payment of the interest due on
such interest payment date, in which case such defaulted interest shall be paid
to the persons in whose names Outstanding Securities are registered at the close
of business on a subsequent record date (which shall be not less than five
Business Days prior to the date of payment of such defaulted interest)
established by notice given by mail by or on behalf of the Issuer to the Holders
of Securities not less than 15 days preceding such subsequent record date.  The
term "record date" as used with respect to any interest payment date (except a
date for payment of defaulted interest) for the Securities shall mean the date
specified as such in the terms of the Securities established as contemplated by
Section 2.3, or, if no such date is so established, if such interest payment
date is the first day of a calendar month, the fifteenth day of the next
preceding calendar month, or, if such interest payment date is the fifteenth day
of a calendar month, the first day of such calendar month, whether or not such
record date is a Business Day.  The Issuer may make payment of any defaulted
interest in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities may be listed, and upon such
notice as may be required by such exchange, if, after notice given by the Issuer
to the Trustee of the proposed payment pursuant to this provision, such payment
shall be deemed practicable by the Trustee.

          Section 2.8  Registration, Transfer and Exchange.  The Issuer will
                       -----------------------------------                  
keep at the Corporate Trust Office a register or registers in which, subject to
such reasonable regulations as it may prescribe, it will provide for the
registration of Securities and the registration of transfer of  Securities.
Such register shall be in written form in the English language or in any other
form capable of being converted into such form within a reasonable time.  At all
reasonable times such register or registers shall be open for inspection by the
Trustee.

          Upon due presentation for registration of transfer of any Security at
any such office or agency to be maintained for the purpose as provided in
Section 3.2, the Issuer shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new Security or
Securities of the same maturity date, interest rate and original issue date in
authorized denominations for a like aggregate principal amount.

                                       16

 
          At the option of the Holder thereof, Securities (other than a Global
Security, except as set forth below) may be exchanged for a Security or
Securities having authorized denominations and an equal aggregate principal
amount, upon surrender of such Securities to be exchanged at the office or
agency of the Issuer that shall be maintained for such purpose in accordance
with Section 3.2 and upon payment, if the Issuer shall so require, of the
charges hereinafter provided.  Whenever any Securities are so surrendered for
exchange, the Issuer shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.  All Securities surrendered upon any exchange or transfer provided for
in this Indenture shall be promptly cancelled and destroyed pursuant to Section
2.10.

          All Securities presented for registration of transfer, exchange,
redemption or payment shall (if so required by the Issuer or the Trustee) be
duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Issuer and the Trustee duly executed by,
the Holder or his attorney duly authorized in writing.

          The Issuer may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities.  No service charge shall be made for any
such transaction.

          The Issuer shall not be required to exchange or register a transfer of
(a) any Securities for a period of 15 days next preceding the first mailing of
notice of redemption of Securities to be redeemed or (b) any Securities
selected, called or being called for redemption, in whole or in part, except, in
the case of any Security to be redeemed in part, the portion thereof not so to
be redeemed.

          Notwithstanding any other provision of this Section 2.8, unless and
until it is exchanged in whole or in part for Securities in definitive
registered form, a Global Security representing all or a portion of the
Securities may not be transferred except as a whole by the Depositary to a
nominee of such Depositary or by a nominee of such Depositary to such Depositary
or another nominee of such Depositary or by such Depositary or any such nominee
to a successor Depositary or a nominee of such successor Depositary.

          If at any time the Depositary for any Securities represented by one or
more Global Securities notifies the Issuer that it is unwilling or unable to
continue as Depositary for such Securities or if at any time the Depositary for
such Securities shall no longer be eligible under the last paragraph of Section

                                       17

 
2.4, the Issuer shall appoint a successor Depositary eligible under the last
paragraph of Section 2.4 with respect to such Securities.  If a successor
Depositary eligible under the last paragraph of Section 2.4 for such Securities
is not appointed by the Issuer within 90 days after the Issuer receives such
notice or becomes aware of such ineligibility, the Issuer's election pursuant to
Section 2.3 that such Securities be represented by one or more Global Securities
shall no longer be effective and the Issuer will execute, and the Trustee, upon
receipt of an Officer's Certificate for the authentication and delivery of
definitive Securities, will authenticate and deliver, Securities in definitive
registered form without coupons, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Global Security
or Global Securities representing such Securities in exchange for such Global
Security or Global Securities.

          The Issuer may at any time and in its sole discretion determine that
the Securities issued in the form of one or more Global Securities shall no
longer be represented by a Global Security or Securities.  In such event the
Issuer will execute, and the Trustee, upon receipt of an Officer's Certificate
for the authentication and delivery of definitive Securities, will authenticate
and deliver, Securities in definitive registered form, in any authorized
denominations, in an aggregate principal amount equal to the principal amount of
the Global Security or Global Securities representing such Securities, in
exchange for such Global Security or Global Securities.

          If specified by the Issuer pursuant to Section 2.3 with respect to
Securities represented by a Global Security, the Depositary for such Global
Security may surrender such Global Security in exchange in whole or in part for
Securities in definitive registered form on such terms as are acceptable to the
Issuer and such Depositary.  Thereupon, the Issuer shall execute, and the
Trustee shall authenticate and deliver, without service charge,

          (i)  to the person specified by such Depositary a new Security or
     Securities, of any authorized denominations as requested by such person, in
     an aggregate principal amount equal to and in exchange for such person's
     beneficial interest in the Global Security; and

          (ii)  to such Depositary a new Global Security in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     Global Security and the aggregate principal amount of Securities
     authenticated and delivered pursuant to clause (i) above.

                                       18

 
          Upon the exchange of a Global Security for Securities in definitive
registered form, in authorized denominations, such Global Security shall be
cancelled by the Trustee or, upon instruction from the Trustee, an agent of the
Issuer or the Trustee.  Securities in definitive registered form issued in
exchange for a Global Security pursuant to this Section 2.8 shall be registered
in such names and in such authorized denominations as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee or an agent of the Issuer
or the Trustee.  The Trustee or such agent shall deliver such Securities to or
as directed by the persons in whose names such Securities are so registered.

          All Securities issued upon any transfer or exchange of Securities
shall be valid obligations of the Issuer, evidencing the same debt, and entitled
to the same benefits under this Indenture, as the Securities surrendered upon
such transfer or exchange.

          Section 2.9  Mutilated, Defaced, Destroyed, Lost and Stolen
                       ----------------------------------------------
Securities.  In case any temporary or definitive Security shall become
- ----------
mutilated, defaced or be destroyed, lost or stolen and, in the absence of notice
to the Issuer or the Trustee that the Security has been purchased by a bona fide
purchaser, the Issuer in its discretion may execute, and upon an Issuer Order,
the Trustee shall authenticate and deliver a new Security of the same maturity
date, interest rate and original issue date, bearing a number or other
distinguishing symbol not contemporaneously outstanding, in exchange and
substitution for the mutilated or defaced Security, or in lieu of and in
substitution for the Security so destroyed, lost or stolen.  In every case the
applicant for a substitute Security shall furnish to the Issuer and to the
Trustee and any agent of the Issuer or the Trustee such security or indemnity as
may be required by them to indemnify and defend and to save each of them
harmless and, in every case of destruction, loss or theft, evidence to their
satisfaction of the destruction, loss or theft of such Security and of the
ownership thereof and in the case of mutilation or defacement shall surrender
the Security to the Trustee or such agent.

          Upon the issuance of any substitute Security, the Issuer may require
the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses (including the
fees and expenses of the Trustee or its agents) connected therewith.  In case
any Security which has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Issuer may instead of issuing a substitute Security, pay or
authorize the payment of

                                       19

 
the same (without surrender thereof except in the case of a mutilated or defaced
Security) if the applicant for such payment shall furnish to the Issuer and to
the Trustee and any agent of the Issuer or the Trustee such security or
indemnity as any of them may require to save each of them harmless, and, in
every case of destruction, loss or theft, the applicant shall also furnish to
the Issuer and the Trustee and any agent of the Issuer or the Trustee evidence
to their satisfaction of the destruction, loss or theft of such Security and of
the ownership thereof.

          Every substitute Security issued pursuant to the provisions of this
Section by virtue of the fact that any Security is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Issuer, whether or
not the destroyed, lost or stolen Security shall be at any time enforceable by
anyone and shall be entitled to all the benefits of (but shall be subject to all
the limitations of rights set forth in) this Indenture equally and
proportionately with any and all other Securities of duly authenticated and
delivered hereunder.  All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced or
destroyed, lost or stolen Securities and shall preclude 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 2.10  Cancellation of Securities; Destruction Thereof.  All
                        -----------------------------------------------      
Securities surrendered for payment, redemption, registration of transfer or
exchange, or for credit against any payment in respect of a sinking or analogous
fund, if surrendered to the Issuer or any agent of the Issuer or the Trustee or
any agent of the Trustee, shall be delivered to the Trustee or its agent for
cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no
Securities shall be issued in lieu thereof except as expressly permitted by any
of the provisions of this Indenture.  All cancelled Securities held by the
Trustee or its agents shall be destroyed and certification of their destruction
delivered to the Issuer unless, by an Issuer Order, the Issuer shall direct that
cancelled Securities be returned to it.  If the Issuer or its agent shall
acquire any of the Securities, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such Securities
unless and until the same are delivered to the Trustee or its agent for
cancellation.

          Section 2.11  Temporary Securities.  Pending the preparation of
                        --------------------                             
definitive Securities, the Issuer may execute and upon an Issuer Order the
Trustee shall authenticate and deliver

                                       20

 
temporary Securities (printed, lithographed, typewritten or otherwise
reproduced, in each case in form satisfactory to the Trustee).  Temporary
Securities shall be issuable as Securities of any authorized denomination, and
substantially in the form of the definitive Securities but with such omissions,
insertions and variations as may be appropriate for temporary Securities, all as
may be determined by the Issuer with the concurrence of the Trustee as evidenced
by the execution and authentication thereof.  Temporary Securities may contain
such references to any provisions of this Indenture as may be appropriate.  Any
such temporary Securities may be in global form, representing such of the
Outstanding Securities of such series as shall be specified therein.  Every
temporary Security shall be executed by the Issuer and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Securities.  Without unreasonable delay the
Issuer shall execute and shall furnish definitive Securities and thereupon
temporary Securities may be surrendered in exchange therefor without charge at
each office or agency to be maintained by the Issuer for that purpose pursuant
to Section 3.2, and the Trustee shall authenticate and deliver in exchange for
such temporary Securities an equal aggregate principal amount of definitive
Securities having authorized denominations.  Until so exchanged, the temporary
Securities shall be entitled to the same benefits under this Indenture as
definitive Securities, unless otherwise established pursuant to Section 2.3.

          Section 2.12  CUSIP Numbers.  The Issuer in issuing the Securities may
                        -------------

"CUSIP" numbers in notices of redemption as a convenience to Holders; provided
                                                                      --------
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained

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


          Section 3.1  Payment of Principal and Interest.  The Issuer covenants
                       ---------------------------------                       
and agrees for the benefit of the Holders of Securities that it will duly and
punctually pay or cause to be paid the principal of, and interest on, each of
the Securities (together with any additional amounts, payable pursuant to the
terms of such Securities) at the place or places, at the respective times and in
the manner provided in such Securities

                                       21

 
and in this Indenture.  The interest on Securities (together with any additional
amounts payable pursuant to the terms of such Securities) shall be payable only
to, or upon the written order of, the Holders thereof and at the option of the
Issuer may be paid by mailing checks for such interest payable to or upon the
written order of such Holders at their last addresses as they appear on the
register of the Issuer with respect to such Securities.

          Section 3.2  Offices for Payments, etc.  The Issuer will maintain in
                       -------------------------                              
the Borough of Manhattan, the City of New York, an office or agency where the
Securities may be presented for payment or where interest on such securities may
be paid, an office or agency where the Securities may be presented for exchange
as is provided in this Indenture and, if applicable, pursuant to Section 2.8 an
office or agency where the Securities may be presented for registration of
transfer as provided in this Indenture.  The Issuer hereby initially appoints
the office of the Trustee care/of Manufacturers Hanover Trust Company, Bank
Window, 55 Water Street, 2nd Floor, New York, New York  10041 as its offices or
agencies for each of the foregoing purposes.

          The Issuer will maintain in the Borough of Manhattan, the City of New
York, an office or agency where notices and demands to or upon the Issuer in
respect of the Securities or this Indenture may be served.  The Issuer hereby
initially appoints the office of Wachovia International Banking Corporation, 152
West 57th Street, 37th Floor, New York, New York 10019 (c/o Wachovia Bank of
Georgia, N.A.) as its office or agency where notices and demands to or upon the
Issuer in respect of the Securities or this Indenture may be served.

          The Issuer will give to the Trustee written notice of the location of
each such office or agency and of any change of location thereof.  In case the
Issuer shall fail to maintain any office or agency required by this Section to
be located in the Borough of Manhattan, the City of New York, or shall fail to
give such notice of the location or of any change in the location of any of the
above offices or agencies, presentations and demands may be made and notices may
be served at the Corporate Trust Office of the Trustee.

          The Issuer may from time to time designate one or more additional
offices or agencies where the Securities appertaining thereto may be presented
for payment, where interest on such Securities may be paid, where the Securities
may be presented for exchange as provided in this Indenture, where the
Securities may be presented for registration of transfer as provided in this
Indenture, and where notices and demands to or upon the Issuer in respect of the
Securities and this Indenture may be served, and the Issuer may from time to
time rescind any such designation, as

                                       22

 
the Issuer may deem desirable or expedient; provided, however, that no such
                                            --------  -------              
designation or rescission shall in any manner relieve the Issuer of its
obligation to maintain the offices or agencies provided for in the immediately
preceding paragraphs.  The Issuer hereby initially appoints the office of the
Trustee set forth in Section 11.4 as such an additional office.  The Issuer will
give to the Trustee prompt written notice of any such additional designation or
any such rescission thereof.

          Section 3.3  Appointment to Fill a Vacancy in Office of Trustee.  The
                       --------------------------------------------------      
Issuer, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 6.9, a Trustee, so that there
shall at all times be a Trustee with respect to the Securities hereunder.

          Section 3.4  Paying Agents.  Unless otherwise specified in a
                       -------------                                  
resolution, the Trustee for any series of Securities shall also act as the
paying agent for such series of Securities.  Whenever the Issuer shall appoint a
paying agent other than the Trustee with respect to any series of Securities, it
will cause such paying agent to execute and deliver to the Trustee an instrument
in which such agent shall agree with the Trustee, subject to the provisions of
this Section, that such paying agent,

          (a)  will hold all sums received by it as such agent for the payment
     of the principal of or interest on such series of Securities (whether such
     sums have been paid to it by the Issuer or by any other obligor on such
     series of Securities) in trust for the benefit of the holders of such
     series of Securities) or of the Trustee, until such sums shall be paid to
     such Holders or otherwise disposed of as herein provided;

          (b)  will give the Trustee notice of any failure by the Issuer (or by
     any other obligor on such series of Securities) to make any payment of the
     principal of or interest on such series of Securities when the same shall
     be due and payable; and

          (c)  at any time during the continuance of any such failure, upon the
     written request of the Trustee, it will forthwith pay to the Trustee all
     sums so held in trust by such paying agent.

          The Issuer will, on or prior to each due date of the principal of or
interest on such series of Securities, deposit with the paying agent a sum
sufficient to pay such principal or interest so becoming due, and (unless such
paying agent is the Trustee) the Issuer will promptly notify the Trustee of its
action or any failure to take such action.

                                       23

 
          If the Issuer shall act as its own paying agent with respect to such
series of Securities, it will, on or before each due date of the principal of or
interest on such series of Securities, set aside, segregate and hold in trust
for the benefit of the holders of such series of Securities a sum sufficient to
pay such principal or interest so becoming due.  The Issuer will promptly notify
the Trustee of its action or any failure to take such action.

          Anything in this Section to the contrary notwithstanding, the Issuer
may at any time, for the purpose of obtaining a satisfaction and discharge with
respect to such series of Securities hereunder, or for any other reason, pay or
cause to be paid, or by Issuer Order direct any paying agent to pay to the
Trustee all sums held in trust by the Issuer or any paying agent hereunder, as
required by this Section, such sums to be held by the Trustee upon the trusts
herein contained.

          Anything in this Section to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Sections 10.3 and 10.4.

          Section 3.5  Statements as to Compliance.  The Issuer will deliver to
                       ---------------------------                             
the Trustee annually, commencing July 1, 1993, a certificate, dated June 30 of
each such year, of its principal executive officer, principal financial officer
or principal accounting officer, stating whether or not to the best knowledge of
the signer thereof, after a review of the activities of the Issuer during such
year ending June 30 (or since the date of this Indenture for the certificate
dated July 1, 1993) and performance under this Indenture has been made under
such signer's supervision, the Issuer is in compliance (without regard to
periods of grace or notice requirements) with all conditions and covenants under
this Indenture, and if the Issuer shall not be in compliance, specifying such
non-compliance and the nature and status thereof as to which such signer may
have knowledge.

          Section 3.6  Merger, Consolidation or Sale of Assets.  The Issuer will
                       ---------------------------------------                  
not merge or consolidate with or into, or sell, lease, convey or otherwise
dispose of, directly or indirectly, all or substantially all of its properties
or assets to another corporation, person or entity (whether or not affiliated
with the Company) in one transaction or a series of related transactions except
as permitted in Section 9.1.

          Section 3.7  Limitation on Liens.
                       ------------------- 

          The Issuer will not, and will not permit any Subsidiary to, directly

               (e)  any final non-appealable judgment or order for the payment
     of money in excess of $10,000,000 shall be rendered against the Issuer and
     either (i) enforcement proceedings shall have been commenced by any
     creditor upon such judgment or order or (ii) there shall be any period of
     30 consecutive days during which a stay of enforcement of such judgment or
     order, by reason of a pending appeal or otherwise, shall not be in effect;

               (f)  a court having jurisdiction in the premises shall enter a
     decree or order for relief in respect of the Issuer in an involuntary case
     under any applicable bankruptcy, insolvency or other similar law now or
     hereafter in effect, or appointing a receiver, liquidator, assignee,

               (i) any other event of default established by or pursuant to a
     Board Resolution, an Officer's Certificate or in the supplemental indenture
     under which such series of Securities are issued or in the form of such
     Security.

          Section 5.2  Acceleration of Maturity; Recission and Annulment.  If an
                       -------------------------------------------------        
Event of Default described in clause (f), (g) or (h) occurs and is continuing,
then, and in each and every such case, the entire principal (or, if any
Securities are Original Issue Discount Securities, such portion of the principal
as may be specified in the terms thereof) of all the Securities then
Outstanding, and the interest accrued thereon, if any, shall become immediately
due and payable.

          If an Event of Default with respect to a particular series of
Securities described in clauses (a), (b), (c), (d), (e) or (i) occurs and is
continuing, then, and in each and every such case, either the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities of such series by notice in writing to the Issuer (and to the Trustee
if given by Securityholders), may declare the entire principal (or, if such
Securities are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of such Securities) of all Securities of
such series and the interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration, the same shall become immediately
due and payable.

          The foregoing provisions, however, are subject to the condition that
if, at any time after the principal (or, if the Securities are Original Issue
Discount Securities, such portion of the principal as may be specified in the
terms of that series) of any particular series of Securities shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, the
Issuer shall pay or shall deposit with the Trustee a sum sufficient to pay all
matured installments of interest upon all the Securities of such series and the
principal of any and all Securities of such series which shall have become due
otherwise than by acceleration (with interest upon such principal and, to the
extent that payment of such interest is enforceable under applicable law, on
overdue installments of interest, at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified
in the terms of such series to the date of such payment or deposit) and such
amount as shall be sufficient to cover reasonable compensation to the Trustee
and each predecessor Trustee, their respective agents, attorneys and counsel,
and all other reasonable expenses and liabilities incurred, and all reasonable
advances made, by the Trustee and each predecessor Trustee except as a result of
negligence or bad

                                       31

 
faith, and if any and all Events of Default under the Indenture, other than the
non-payment of the principal of Securities of such series which shall have
become due by acceleration, shall have been cured, waived or otherwise remedied
as provided herein, then and in every such case the Holders of a majority in
aggregate principal amount of such series of Securities then Outstanding, by
written notice to the Issuer and to the Trustee, may rescind and annul such
declaration and its consequences but no such rescission and annulment shall
extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

          For all purposes under this Indenture, if a portion of the principal
of any Original Issue Discount Securities of a particular series shall have been
accelerated and declared due and payable pursuant to the provisions hereof,
then, from and after such declaration, unless such declaration has been
rescinded and annulled, the principal amount of any such Original Issue Discount
Securities shall be deemed, for all purposes hereunder, to be such portion of
the principal thereof as shall be due and payable as a result of such
acceleration, and payment of such portion of the principal thereof as shall be
due and payable as a result of such acceleration, together with interest, if
any, thereon and all other amounts owing thereunder, shall constitute payment in
full of such Original Issue Discount Securities.

          Section 5.3  Collection of Indebtedness by Trustee; Trustee May Prove
                       --------------------------------------------------------
Debt.  (a) The Issuer covenants that (i) in case default shall be made in the
- ----                                                                         
payment of any installment of interest on any series of Securities when such
interest shall have become due and payable and such default shall have continued
for a period of 30 days or (ii) in case default shall be made in the payment of
all or any part of the principal of any series of Securities when the same shall
have become due and payable, whether upon maturity of such series of Securities
or upon any redemption or by acceleration or otherwise, then upon demand of the
Trustee, the Issuer will pay to the Trustee for the benefit of the Holders of
such series of Securities the whole amount that then shall have become due and
payable on all such Securities for principal or interest as the case may be
(with interest to the date of such payment upon the overdue principal and, to
the extent that payment of such interest is enforceable under applicable law, on
overdue installments of interest at the same rate as the rate of interest (or
Yield to Maturity in the case of Original Issue Discount Securities) specified
in such series of Securities); and in addition thereto, such further amount as
shall be sufficient to cover the reasonable costs and expenses of collection,
including reasonable compensation to the Trustee and each predecessor Trustee,
their respective agents, attorneys and counsel, and any reasonable expenses and
liabilities incurred, and all reasonable disbursements and advances made, by the

                                       32

 
Trustee and each predecessor Trustee except as a result of its negligence or bad
faith.

          Until such demand is made by the Trustee, the Issuer may pay the
principal of and interest on such Securities to the registered Holders, whether
or not such Securities are overdue.

          In case the Issuer 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 action or proceeding 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 Issuer or other obligor upon such series of
Securities and collect in the manner provided by law out of the property of the
Issuer or other obligor upon such series of Securities, wherever situated, the
moneys adjudged or decreed to be payable.

          (b) If an Event of Default specified in Section 5.1(a) or (b) occurs
and is continuing with respect to a series of Securities and the Issuer fails to
pay such amounts forthwith upon demand, the Trustee may recover judgment in its
own name and as trustee of an express trust against the Issuer for the
collection of such sums due and unpaid.

          Section 5.4   Trustee May File Proofs of Claim.  In case there shall
                        --------------------------------                      
be pending proceedings relative to the Issuer or any other obligor upon any
Securities under Title 11 of the United States Code or any other applicable
Federal or state bankruptcy, insolvency or other similar law or in case a
receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for, or taken
possession of, the Issuer or its property or such other obligor, or in case of
any other comparable judicial proceedings relative to the Issuer or other
obligor upon such Securities, or to the creditors or property of the Issuer or
such other obligor, the Trustee (irrespective of whether the principal of any
such Securities 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) shall be entitled and
empowered, by intervention in such proceedings or otherwise:

               (a)  to file and prove a claim or claims for the whole amount of
     principal and interest (or, if such Securities are Original Issue Discount
     Securities, such portion of the principal amount as may be specified in the
     terms of such Securities) owing and unpaid in respect of such Securities,
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims

                                       33

 
     of the Trustee (including any claim for reasonable compensation to the
     Trustee and each predecessor Trustee, and their respective agents,
     attorneys and counsel, and for reimbursement of all expenses and
     liabilities incurred, and all disbursements and advances made, by the
     Trustee and each predecessor Trustee, except as a result of negligence or
     bad faith) and of the Holders of such Securities allowed in any judicial
     proceedings relative to the Issuer or other obligor upon such Securities,
     or to the creditors or property of the Issuer or such other obligor;

               (b)  unless prohibited by applicable law and regulations, to vote
     on behalf of the Holders of such Securities in any election of a trustee or
     a standby trustee in arrangement, reorganization, liquidation or other
     bankruptcy or insolvency proceedings or person performing similar functions
     in comparable proceedings; and

               (c)  to collect and receive any moneys or other property payable
     or deliverable on any such claims, and to distribute all amounts received
     with respect to the claims of the Securityholders of such series and of the
     Trustee on their behalf;

and any trustee, receiver, liquidator, custodian or other similar official is
hereby authorized by each of the Securityholders of such series to make payments
to the Trustee, and, in the event that the Trustee shall consent to the making
of payments directly to the Securityholders of such series, to pay to the
Trustee such amounts as shall be sufficient to cover reasonable compensation to
the Trustee, each predecessor Trustee and their respective agents, attorneys and
counsel, and all other expenses and liabilities incurred, and all advances made,
by the Trustee and each predecessor Trustee and all other amounts due the
Trustee under Section 6.6 in each case except as a result of negligence or bad
faith.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder of such series any plan of reorganization, arrangement,
adjustment or composition affecting the Securities of such series or the rights
of any Holder thereof, or to authorize the Trustee to vote in respect of the
claim of any Securityholder in any such proceeding except, as aforesaid, to vote
for the election of a trustee in bankruptcy or similar person.

Securities.  All rights of action and of asserting claims under this Indenture,

or under any of the Securities may be enforced by the Trustee without the
possession of any of the

Securities or the production thereof in any trial or other proceedings relative
thereto, and any such action or proceedings 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 expenses, disbursements, compensation
and advances of the Trustee, each predecessor Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the Holders of the
Securities in respect of which such action was taken.  In any proceedings
brought by the Trustee (and also any proceedings involving the interpretation of
any provision of this Indenture to which the Trustee shall be a party) the
Trustee shall be held to represent all the Holders of the Securities in respect
to which such action was taken, and it shall not be necessary to make any
Holders of such Securities parties to any such proceedings.

                       -----------------------                              
Trustee pursuant to this Article in respect of any particular series of
Securities shall be applied in the following order at the date or dates fixed by
the Trustee and, in case of the distribution of such moneys on account of
principal or interest, upon presentation of the several Securities in respect of
which monies have been collected and stamping (or otherwise noting) thereon the
payment, or issuing Securities in reduced amounts in exchange for the presented
Securities if only partially paid, or upon surrender thereof if fully paid:

          FIRST:  To the payment of costs and expenses with respect to such
     series in respect of which monies have been collected, including payment of
     all amounts due the Trustee and each predecessor Trustee under Section 6.6,
     and all advances made by the Trustee and each predecessor Trustee and their
     respective agents and attorneys except as a result of negligence or bad
     faith;

          SECOND:  In case the principal of the Securities in respect of which
     moneys have been collected shall not have become and be then due and
     payable, to the payment of interest on the Securities in default in the
     order of the maturity of the installments of such interest, with interest
     (to the extent that such interest has been collected by the Trustee) upon
     the overdue installments of interest at the same rate as the rate of
     interest or Yield to Maturity (in the case of Original Issue Discount
     Securities) specified in such Securities, such payments to be made ratably
     to the persons entitled thereto, without discrimination or preference;

          THIRD:  In case the principal of the Securities in respect of which
     moneys have been collected shall have become and shall be then due and
     payable, to the payment of

     the whole amount then owing and unpaid upon all the Securities for
     principal and interest, with interest upon the overdue principal, and (to
     the extent that such interest has been collected by the Trustee) upon
     overdue installments of interest at the same rate as the rate of interest
     or Yield to Maturity (in the case of Original Issue Discount Securities)
     specified in the Securities; and in case such moneys shall be insufficient
     to pay in full the whole amount so due and unpaid upon the Securities, then
     to the payment of such principal and interest or Yield to Maturity, without
     preference or priority of principal over interest or Yield to Maturity, or
     of interest or Yield to Maturity over principal, or of any installment of
     interest over any other installment of interest, or of any Security over
     any other Security, ratably to the aggregate of such principal and accrued
     and unpaid interest or Yield to Maturity; and

          FOURTH:  To the payment of the remainder, if any, to the Issuer or any
     other person lawfully entitled thereto.

                       ---------------------                                  
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

          Section 5.8  Restoration of Rights on Abandonment of Proceedings.  In
                       ---------------------------------------------------     
case the Trustee or any Holder shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
for any reason, or shall have been determined adversely to the Trustee or to
such Holder, then and in every such case the Issuer, the Trustee and the
Securityholders shall be restored respectively to their former positions and
rights hereunder, and all rights, remedies and powers of the Issuer, the Trustee
and the Securityholders shall continue as though no such proceedings had been
taken.

any Security of any particular series shall have any right by virtue or by
availing of any provision of this Indenture to institute any action or
proceeding at law or in equity or in bankruptcy or otherwise upon or under or
with respect to this Indenture, or for the appointment of a trustee, receiver,
liquidator, custodian or other similar official or for any other

                                       36

 
remedy hereunder, unless an Event of Default with respect to that series shall
have occurred and be continuing and such Holder previously shall have given to
the Trustee written notice of default and of the continuance thereof, as
hereinbefore provided, and unless also the Holders of not less than 25% in
aggregate principal amount of the Securities of such series then Outstanding
shall have made written request upon the Trustee to institute such action or
proceedings 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
failed to institute any such action or proceeding and no direction inconsistent
with such written request shall have been given to the Trustee pursuant to
Section 5.13; it being understood and intended, and being expressly covenanted
by the Holder of every Security with every other Holder and the Trustee, that no
one or more Holders of Securities shall have any right in any manner whatever by
virtue or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other such Holder of Securities, or to obtain or
seek to obtain priority over or preference to any other such Holder or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all Holders of Securities of a
particular series.  For the protection and enforcement of the provisions of this
Section, each and every Securityholder and the Trustee shall be entitled to such
relief as can be given at law or in equity.

          Section 5.10  Unconditional Right of Securityholders to Institute
                        ---------------------------------------------------
Certain Suits.  Notwithstanding any other provision in this Indenture and any
- -------------                                                                
provision of any Security, the right of any Holder of any Security to receive
payment of the principal of and interest on such Security on or after the
respective due dates expressed in such Security, or to institute suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

conferred upon or reserved to the Trustee or to the Holders of Securities is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise.  The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

the Trustee or of any Holder of Securities to exercise any right or power
accruing upon any Event of Default occurring and continuing as aforesaid shall
impair any such right or power or shall be construed to be a waiver of any such
Event of Default or an acquiescence therein; and, subject to Section 5.9, every
right, power and remedy given by this Indenture or by law to the Trustee or to
the Holders of Securities may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Holders of Securities.

majority in aggregate principal amount of the Securities of any particular
series at the time Outstanding shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred on the Trustee with respect to the
Securities of such series by this Indenture; provided that such direction shall
                                             --------                          
not be otherwise than in accordance with law and the provisions of this
Indenture and, provided, further, that (subject to the provisions of Section
               --------  -------                                            
6.1) the Trustee shall have the right to decline to follow any such direction if
the Trustee, being advised by counsel, shall determine that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith
by its board of directors, the executive committee, or a trust committee of
directors or Responsible Officer of the Trustee shall determine that the action
or proceedings so directed would expose the Trustee to any liability or if the
Trustee in good faith shall so determine that the actions or forebearances
specified in or pursuant to such direction would be unduly prejudicial to the
interests of Holders of the Securities not joining in the giving of said
direction, it being understood that (subject to Section 6.1) the Trustee shall
have no duty to ascertain whether or not such actions or forebearances are
unduly prejudicial to such Holders.

          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 or directions by Securityholders.

          Section 5.14  Waiver of Past Defaults.  Prior to the acceleration of
                        -----------------------                               
the maturity of any Securities of any particular series as provided in Section
5.1, the Holders of a majority in aggregate principal amount of the Securities
of such series at the time Outstanding with respect to which an Event of Default
shall have occurred and be continuing may on behalf of the Holders of all such
Securities of such series, upon written notice to the Trustee, waive any past
default or Event of Default

                                       38

 
described in Section 5.1 and its consequences, except a default in respect of a
covenant or provision hereof which cannot be modified or amended without the
consent of the Holder of each Security affected.  In the case of any such
waiver, the Issuer, the Trustee and Holders of all such Securities of such
series shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other default
or Event of Default or impair any right consequent thereon.

          Upon any such waiver, such default shall cease to exist and be deemed
to have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured, and not to have occurred for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

          Section 5.15  Trustee to Give Notice of Default, but may Withhold in
                        ------------------------------------------------------
Certain Circumstances.  The Trustee shall, within 90 days after the occurrence

of any default with respect to the Securities of any particular series, give
notice of such default known to the Trustee to all Holders of Securities of such
series in the manner and to the extent provided in Sections 3.4 and 11.4, unless
in each case such defaults shall have been cured before the mailing or
publication of such notice (the term "defaults" for the purpose of this Section
being hereby defined to mean any event or condition which is, or with notice or
lapse of time or both would become, an Event of Default); provided that, except
                                                          --------             
in the case of default in the payment of the principal of or interest on any of
the Securities, or in the payment of any sinking fund installment, 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 or
trustees and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interests of the Securityholders

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

                           CONCERNING THE TRUSTEE
                           ----------------------


          Section 6.1  Duties and Responsibilities of the Trustee; During
                       --------------------------------------------------
Default; Prior to Default.  The Trustee, prior to the occurrence of an Event of
- -------------------------                                                      
Default with respect to the Securities of any particular series and after the
curing or waving 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 with respect to the Securities of any
particular series has occurred (which has not been cured or waived) the Trustee
shall exercise with respect to the Securities of such series such of the rights
and powers vested in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his 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 wilful misconduct, except that

          (a)  prior to the occurrence of an Event of Default with respect to
     the Securities of any particular series and after the curing or waiving of
     all such Events of Default which may have occurred:

               (i)  the duties and obligations of the Trustee with respect to
          the Securities of such series 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

                                       40

 
               (ii) in the absence of bad faith 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
          statements, certificates or opinions furnished to the Trustee and
          conforming to the requirements of this Indenture; but in the case of
          any such statements, certificates or opinions which by any provision
          hereof are specifically required to be furnished to the Trustee, the
          Trustee shall be under a duty to examine the same to determine whether
          or not they conform to the requirements of this Indenture;

          (b)   the Trustee shall not be liable for any error of judgment
made in good faith by a Responsible Officer or Responsible 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 or omitted to be taken by it in good faith in accordance with the
direction of the Holders pursuant to Section 5.9 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 or in the exercise of any of
its rights or powers.

          The provisions of this Section 6.1 are in furtherance of and subject
to Section 315 of the Trust Indenture Act of 1939.

          Section 6.2  Certain Rights of the Trustee.  In furtherance of and

subject to the Trust Indenture Act of 1939, and subject to Section 6.1:

               (a)  the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, Officer's Certificate or any
     other certificate, statement, instrument, opinion, report, notice, request,
     consent, order, bond, debenture, note, security or other paper or document
     believed by it to be genuine and to have been signed or presented by the
     proper party or parties and the Trustee need not investigate any fact or
     matter stated in any such document;

                                       41

 
               (b) any request, direction, order or demand of the Issuer
     mentioned herein shall be sufficiently evidenced by an Officer's
     Certificate (unless other evidence in respect thereof be herein
     specifically prescribed); and any resolution of the Board of Directors may
     be evidenced to the Trustee by a copy thereof certified by the secretary or
     an assistant secretary of the Issuer;

               (c)  whenever in the administration of this Indenture the Trustee
     shall deem it desirable that a matter be proved or established prior to
     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence be herein specifically prescribed) may, in the absence of
     bad faith on its part, rely upon an Officer's Certificate;

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

               (e)  the Trustee shall be under no obligation to exercise any of
     the trusts or powers vested in it by this Indenture at the request, order
     or direction of any of the Securityholders pursuant to the provisions of
     this Indenture, unless such Securityholders shall have offered to the
     Trustee security and indemnity reasonably satisfactory to the Trustee
     against any costs, expenses and liabilities which might be incurred therein
     or thereby;

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

               (g)  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, appraisal, bond, debenture, note,
     security or other paper or document unless requested in writing to do so by
     the Holders of not less than a majority in aggregate principal amount of
     the Securities of a series then Outstanding; provided that, if the payment
                                                  --------                     
     within a reasonable time to the Trustee of the costs, expenses, or
     liabilities (including, without limitation reasonable fees and expenses of
     counsel) which are likely to be incurred by it in the making of such

                                       42

 
     investigation is, in the opinion of the Trustee, not reasonably assured to
     the Trustee by the security and indemnity afforded to it by the terms of
     this Indenture, the Trustee may require indemnity and security reasonably
     satisfactory to it against such costs, expenses or liabilities as a
     condition to proceeding; all such costs and expenses of every such
     investigation shall be paid by the Issuer or, if paid by the Trustee or any
     predecessor Trustee, shall be repaid by the Issuer upon demand; and

               (h)  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 not regularly in its employ and the Trustee shall not
     be responsible for any misconduct or negligence on the part of any such
     agent or attorney appointed with due care by it hereunder.

                       ----------------------------------------------------
Securities or Application of Proceeds Thereof.  The recitals contained herein
- ---------------------------------------------                                
and in the Securities, except the Trustee's certificates of authentication,
shall be taken as the statements of the Issuer, 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
Securities.  The Trustee shall not be accountable for the use or application by
the Issuer of any of the Securities or of the proceeds thereof.

          Section 6.4  Trustee and Agents May Hold Securities; Collections, etc.
                       ---------------------------------------------------------
The Trustee or any agent of the Issuer or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such
agent; provided, however, that the Trustee must comply with Section 6.13.

          Section 6.5  Moneys Held by Trustee.  Subject to the provisions of
                       ----------------------                               
Section 10.4 hereof, 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 mandatory provisions of law.  Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any
moneys received by it hereunder.

          Section 6.6  Compensation and Indemnification of Trustee and Its Prior
                       ---------------------------------------------------------
Claim.  The Issuer covenants and agrees to pay to the Trustee from time to time,
- -----                                                                           
and the Trustee shall be entitled to, reasonable compensation as shall be agreed
to in

                                       43

 
writing between the Issuer and the Trustee (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
and the Issuer covenants and agrees to pay or reimburse the Trustee and each
predecessor Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by or on behalf of it in accordance with any of
the provisions of this Indenture (including the reasonable compensation,
expenses and disbursements of its counsel and of all agents and other persons
not regularly in its employ) except any such expense, disbursement or advance as
may arise from its negligence or bad faith.  The Issuer also covenants to
indemnify and hold harmless the Trustee and each predecessor Trustee, and the
directors, officers, employees and agents of each thereof, for and against, any
and all loss, liability or expense incurred without negligence or bad faith on
such party's part (including, without limitation, reasonable fees and expenses
of its counsel), arising out of or in connection with the acceptance or
administration of this Indenture or the trusts hereunder and its duties
hereunder, including the costs and expenses of defending itself against or
investigating any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.  The obligations of the
Issuer under this Section 6.6 to compensate and indemnify the Trustee and each
predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for losses, costs, liabilities, expenses, disbursements and advances
shall constitute additional indebtedness hereunder and shall survive the
satisfaction and discharge of this Indenture.  Such additional indebtedness
shall be a senior claim to that of the Securities upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
payment of principal of or interest on particular Securities, and the Securities
are hereby subordinated to such senior claim and the Trustee shall have a lien
therefor prior to the Securities on all such property and funds.  Such lien
shall survive the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.1(f) or Section 5.1(g), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

          Section 6.7  Right of Trustee to Rely on Officer's Certificate, etc.
                       ------------------------------------------------------  
Subject to Sections 6.1 and 6.2, whenever in the administration of the trusts of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof

                                       44

 
be herein specifically prescribed) may, in the absence of negligence or bad
faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officer's Certificate delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith 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 upon the faith thereof.

          Section 6.8  Persons Eligible for Appointment as Trustee;
                       --------------------------------------------
Disqualification.  This Indenture shall always have a Trustee who satisfies the
- ----------------                                                               
requirements of Section 310(a) of the Trust Indenture Act of 1939.  The Trustee
shall at all times be a corporation organized and doing business under the laws
of the United States of America or of any State or the District of Columbia
having a combined capital and surplus of at least $10,000,000, and which is
authorized under such laws to exercise corporate trust powers and is subject to
supervision or examination by Federal, State or District of Columbia authority.
Such corporation shall have a place of business in the Borough of Manhattan, the
City of New York.  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, 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.  In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 6.8 the Trustee shall resign immediately in the
manner and with the effect specified in Section 6.9.

          No obligor upon the Securities or person directly or indirectly
controlling, controlled by or under common control with such obligor shall serve
as Trustee for any series of Securities.

          The Trustee shall comply with Section 310(b) of the Trust Indenture
Act of 1939.

          The provisions of this Section 6.8 are in furtherance of and subject
to Section 310(a) of the Trust Indenture Act of 1939.

          Section 6.9  Resignation and Removal; Appointment of Successor
                       -------------------------------------------------
Trustee.

               (a)  The Trustee, or any trustee or trustees hereafter appointed,
     may at any time resign with respect to the Securities by giving written
     notice of resignation to the Issuer and by mailing notice of such
     resignation to the Holders of then Outstanding Securities at their
     addresses as

                                       45

 
     they shall appear on the registry books.  Upon receiving such notice of
     resignation, the Issuer shall promptly appoint a successor trustee or
     trustees with respect to the Securities by written instrument in duplicate,
     executed by authority of the Board of Directors, one copy of which
     instrument shall be delivered to the resigning Trustee and one copy to the
     successor trustee or trustees.  If no successor trustee shall have been so
     appointed with respect to the Securities 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 Securityholder who has been a
     bona fide Holder of a Security or Securities for at least six months may,
     ---- ----                                                                
     subject to the provisions of Section 5.16, 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:

                    (i)  the Trustee shall fail to comply with the provisions of
          Section 310(b) of the Trust Indenture Act of 1939 with respect to the
          Securities after written request therefor by the Issuer or by any
          Securityholder who has been a bona fide Holder of a Security or
                                        ---- ----                        
          Securities for at least six months; or

                    (ii)  the Trustee shall cease to be eligible in accordance
          with the provisions of Section 6.8 and Section 310(a) of the Trust
          Indenture Act of 1939 and shall fail to resign after written request
          therefor by the Issuer or by any Securityholder; or

                    (iii)  the Trustee shall become incapable of acting with
          respect to the Securities, or shall be adjudged a bankrupt or
          insolvent, or a receiver or liquidator 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; or

                    (iv)  the Trustee and the Issuer fail to agree on the
          Trustee's fees after good faith negotiations;

then, in any such case, the Issuer may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate,

                                       46

 
executed by order of the Board of Directors of the Issuer, 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 315(a) of the Trust
Indenture Act of 1939, any Securityholder who has been a bona fide Holder of a
                                                         ---- ----            
Security or Securities 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 with respect
to the Securities.  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)  The Holders of a majority in aggregate principal amount of
     the Securities at the time Outstanding may at any time remove the Trustee
     and appoint a successor trustee by delivering to the Trustee so removed, to
     the successor trustee so appointed and to the Issuer the evidence provided
     for in Section 7.1 of the action in that regard taken by the
     Securityholders.

               (d)  Any resignation or removal of the Trustee and any
     appointment of a successor trustee pursuant to any of the provisions of
     this Section 6.9 shall become effective upon acceptance of appointment by
     the successor trustee as provided in Section 6.10.

          Section 6.10  Acceptance of Appointment by Successor Trustee.  Any
                        ----------------------------------------------      
successor trustee appointed as provided in Section 6.9 shall execute and deliver
to the Issuer and to its predecessor Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee with respect to the Securities shall become effective and
such successor trustee, without any further act, deed or conveyance, shall
become vested with all rights, powers, duties and obligations with respect to
the Securities of its predecessor hereunder, with like effect as if originally
named as Trustee hereunder; but, nevertheless, on the written request of the
Issuer or of the successor trustee, upon payment of its charges then unpaid, the
trustee ceasing to act shall, subject to Section 10.4, duly assign, transfer and
deliver to the successor trustee all moneys at the time held by it hereunder and
shall execute and deliver an instrument transferring to such successor trustee
all such rights, powers, duties and obligations.  Upon request of any such
successor trustee, the Issuer shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee
all such rights and powers.  Any trustee ceasing to act shall, nevertheless,
retain a prior claim and 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 6.6.

                                       47

 
          If a successor trustee is appointed with respect to the Securities,
the Issuer, the predecessor Trustee and each successor trustee shall execute and
deliver an indenture supplemental hereto which shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder.

          No successor trustee with respect to the Securities shall accept
appointment as provided in this Section 6.10 unless at the time of such
acceptance such successor trustee shall be qualified under Section 310(b) of the
Trust Indenture Act of 1939 and eligible under the provisions of Section 6.8.

          Upon acceptance of appointment by any successor trustee as provided in
this Section 6.10, the Issuer shall give notice thereof to the Holders of
Securities, by mailing such notice to such Holders at their addresses as they
shall appear on the registry books.  If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
6.9.  If the Issuer fails to give such notice within ten days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be given at the expense of the Issuer.

          Section 6.11  Merger, Conversion, Consolidation or Succession to
                        --------------------------------------------------
Business of Trustee.  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, 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, provided that such
                                                          --------          
corporation shall be qualified under Section 310(b) of the Trust Indenture Act
of 1939 and eligible under the provisions of Section 6.8, 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.

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

                                       48

 
have; provided that the right to adopt the certificate of authentication of any
      --------                                                                 
predecessor Trustee or to authenticate Securities in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.

          Section 6.12  Appointment of Authenticating Agent.  As long as any
                        -----------------------------------                 
Securities remain Outstanding, the Trustee may, by an instrument in writing,
appoint with the approval of the Issuer an authenticating agent (the
"Authenticating Agent") which shall be authorized to act on behalf of the
Trustee to authenticate Securities, including Securities issued upon exchange,
registration of transfer, partial redemption or pursuant to Section 2.9.
Securities authenticated by such Authenticating Agent shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee.  Whenever reference is made in this Indenture
to the authentication and delivery of Securities by the Trustee or to the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by such Authenticating Agent.  Such Authenticating Agent shall at
all times be a corporation organized and doing business under the laws of the
United States of America or of any State, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$5,000,000 (determined as provided in Section 6.8 with respect to the Trustee)
and subject to supervision or examination by Federal or state authority.

          Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect of Securities for which it served as Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
or such Authenticating Agent.  Any Authenticating Agent may at any time, and if
it shall cease to be eligible shall, resign by giving written notice of
resignation to the Trustee and to the Issuer.

          Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.12, the Trustee
may, with the approval of the Issuer, appoint a successor Authenticating Agent
and the Issuer shall provide notice of such appointment to all Holders of
Securities in the manner and to the extent provided in

                                       49

 
Section 11.4.  Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all rights, powers, duties and
responsibilities of its predecessor hereunder, with like effect as if originally
named as Authenticating Agent.  The Issuer agrees to pay to the Authenticating
Agent from time to time reasonable compensation.  The Authenticating Agent for
the Securities shall have no responsibility or liability for any action taken by
it as such at the direction of the Trustee.

          Sections 6.2, 6.3, 6.4, 6.6 and 7.3 shall be applicable to any
Authenticating Agent.

          Section 6.13  Preferential Collection of Claims Against the Company.
                        -----------------------------------------------------  
The Trustee shall comply with Section 311(a) of the Trust Indenture Act of 1939,
excluding any creditor relationship listed in Section 311(b) of the Trust
Indenture Act of 1939.  A Trustee who has resigned or been removed shall be
subject to Section 311(a) of the Trust Indenture Act of 1939 to the extent
indicated therein.

                       CONCERNING THE SECURITYHOLDERS
                       ------------------------------


          Section 7.1  Evidence of Action Taken by Securityholders.  Any
                       -------------------------------------------      
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by a specified percentage
in principal amount of the Holders of Securities of any particular series,
including but not limited to the matters set forth in Sections 5.9 and 5.10, may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such specified percentage of Securityholders of such series in
person or by agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee.  Proof of execution of any instrument
or of a writing appointing any such agent shall be sufficient for any purpose of
this Indenture and (subject to Sections 6.1 and 6.2) conclusive in favor of the
Trustee and the Issuer, if made in the manner provided in this Article.

          Section 7.2  Proof of Execution of Instruments and of Holding of
                       ---------------------------------------------------
Securities.  Subject to Sections 6.1 and 6.2, the execution of any instrument by
- ----------                                                                      
a Securityholder or his agent or proxy may be proved in the following manner:

               (a)  The fact and date of the execution by any Holder of any
     instrument may be proved by the certificate of

                                       50

 
     any notary public or other officer of any jurisdiction authorized to take
     acknowledgements of deeds or administer oaths that the person executing
     such instruments acknowledged to him the execution thereof, or by an
     affidavit of a witness to such execution sworn to before any such notary or
     other such officer.  Where such execution is by or on behalf of any legal
     entity other than an individual, such certificate or affidavit shall also
     constitute sufficient proof of the authority of the person executing the
     same.  Subject to Sections 6.1 and 6.2, the fact and date of the execution
     of any such instrument and the amount and numbers of Securities held by the
     person so executing such instrument and the amount and numbers of any
     Security or Securities may also be proven in accordance with such
     reasonable rules and regulations as may be prescribed by the Trustee or in
     any other reasonable manner which the Trustee may deem sufficient.

               (b)  The principal amount and the ownership of such Securities
     shall be proved by the Security register or by a certificate of the
     Security registrar.

          The Issuer may set a record date for purposes of determining the
identity of Holders of Securities entitled to vote or consent to any action
referred to in Section 7.1, which record date may be set at any time or from
time to time by notice to the Trustee, for any date or dates (in the case of any
adjournment or reconsideration) not more than 60 days nor less than five days
prior to the proposed date of such vote or consent, and thereafter,
notwithstanding any other provisions hereof, only Holders of Securities of
record on such record date shall be entitled to so vote or give such consent or
revoke such vote or consent.

          Section 7.3  Holders to Be Treated as Owners.  The Issuer, the Trustee
                       -------------------------------                          
and any agent of the Issuer or the Trustee may deem and treat the person in
whose name any Security shall be registered upon the Security register as the
absolute owner of such Security (whether or not such Security shall be overdue
and notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of and, subject
to the provisions of this Indenture, interest on such Security and for all other
purposes; and neither the Issuer nor the Trustee nor any agent of the Issuer
or the Trustee shall be affected by any notice to the contrary.

          Section 7.4  Securities Owned by Issuer Deemed Not Outstanding.  In
                       -------------------------------------------------     
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any particular series have concurred in any direction,
consent or

                                       51

 
waiver under the Indenture, Securities which are owned by the Issuer or any
other obligor on the Securities with respect to which such determination is
being made or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Issuer or any other obligor
on the Securities with respect to which such determination is being made shall
be disregarded and deemed not to be Outstanding for the purpose of any such
determination, except that for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only
Securities which the Trustee knows are so owned shall be so disregarded.
Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer or any other obligor on such Securities.  In case
of a dispute as to such right, the advice of counsel shall be full protection in
respect of any decision made by the Trustee in accordance with such advice.
Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an
Officer's Certificate listing and identifying all Securities, if any, known by
the Issuer to be owned or held by or for the account of any of the above-
described persons; and, subject to Sections 6.1 and 6.2, the Trustee shall be
entitled to accept such Officer's Certificate as conclusive evidence of the
facts therein set forth and of the fact that all Securities not listed therein
are Outstanding for the purpose of any such determination.

          Section 7.5  Principal Amount of Original Issue Discount Securities.
                       ------------------------------------------------------  
In determining whether the Holders of the requisite principal amount of
Outstanding Securities have given any request, demand, authorization, direction,
notice, consent or waiver under this Indenture, the principal amount of an
Original Issue Discount Security that may be counted in making such
determination and that shall be deemed to be Outstanding for such purposes shall
be equal to the amount of the principal thereof that would be due and payable
upon a declaration of acceleration of the maturity date thereof pursuant to
Section 5.2 at the time the taking of such action by the Holders of such
requisite principal amount is evidenced to the Trustee for such Securities.

          Section 7.6  Right of Revocation of Action Taken.  At any time prior
                       -----------------------------------                    
to (but not after) the evidencing to the Trustee, as provided in Section 7.1, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any particular series, specified in this Indenture
in connection with such action, any Holder of a Security of such series the
serial number of which is shown by the evidence to be

                                       52

 
included among the serial numbers of the Securities of such series the Holders
of which have consented to such action may, by filing written notice at the
Corporate Trust Office and upon proof of holding as provided in this Article,
revoke such action so far as concerns such Security to the extent such Security
would be deemed to be Outstanding pursuant to Section 7.4.  Except as aforesaid,
any such action taken by the Holder of any Security shall be conclusive and
binding upon such Holder and upon all future Holders and owners of such Security
and of any Securities issued in exchange or substitution therefor or on
registration of transfer thereof, irrespective of whether or not any notation in
regard thereto is made upon any such Security.  Any action taken by the Holders
of the percentage in aggregate principal amount of the Securities of any
particular series, specified in this Indenture in connection with such action
shall be conclusively binding upon the Issuer, the Trustee and the Holders of
all the Securities of such series affected by such action.

less than a two-thirds in aggregate principal amount of the Securities of each
affected series at the time Outstanding by such supplemental indenture, the
Issuer, when authorized by a resolution of its Board of Directors (which
resolution may provide general terms or parameters for such action and may
provide that the specific terms of such action may be determined in accordance
with or pursuant to an Issuer Order), and the Trustee may, from time to time and
at any time, enter into an indenture or indentures supplemental hereto for the

any amount in respect of original issue discount), or interest thereon payable
in any coin or currency other than that provided in the Securities of such

consequences) without the consent of the Holders of each Security so affected,
or (c) modify any of the provisions of this Section, except to increase any such
percentage or to provide that certain other provisions of this Indenture cannot
be modified or waived without the consent of the Holder of each Security
affected thereby.

parameters for such action and may provide that the specific terms of such
action may be determined in accordance with or pursuant to an Issuer Order)

the execution of any such supplemental indenture, and upon the filing with the
Trustee of evidence of the consent of the Holders of the Securities of each
affected series as aforesaid and other documents, if any, required by Section

supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee in its discretion may, but shall not be obligated to, enter
into such supplemental indenture.

          It shall not be necessary for the consent of the Securityholders under
this Section 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 by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall give notice thereof to the Holders of then Outstanding Securities
affected, by mailing a notice thereof by first-class mail to such Holders at
their addresses as they shall appear on the Security register, and such notice
shall set forth in general terms the substance of such supplemental indenture.
Any failure of the Issuer to give such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

     Default with respect to any series of Securities, shall have happened and
     be continuing; and

               (3)  the Issuer has delivered to the Trustee for each series of
     Securities an Officers' Certificate and an Opinion of Counsel each stating
     that such consolidation, merger, conveyance or transfer and such
     supplemental indenture comply with the applicable provisions of this
     Indenture and that all conditions precedent herein provided for relating to
     such transaction have been complied with.

          Section 9.2  Successor Issuer Substituted.  In case of any such
                       ----------------------------                      
consolidation, merger, sale or conveyance and upon the assumption by the
successor corporation by supplemental indenture, executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the due and punctual payment
of the principal of and interest on all of the Securities and the due and
punctual performance of all of the covenants and conditions of this Indenture to
be performed by the Issuer, such successor corporation shall succeed to and be
substituted for the Issuer, with the same effect as if it had been named herein
as the Issuer and the predecessor Issuer shall thereupon be released from all
obligations hereunder and under the Securities.  Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Issuer any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Issuer and delivered to the
Trustee; and, upon the order of such successor corporation instead of the Issuer
and subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee or the Authenticating

                                       58

 
Agent on its behalf shall authenticate and shall deliver any Securities which
previously shall have been signed and delivered by the officers of the Issuer to
the Trustee or the Authenticating Agent on its behalf for authentication, and
any Securities which such successor corporation thereafter shall cause to be
signed and delivered to the Trustee or the Authenticating Agent on its behalf
for that purpose.  All the Securities so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Securities theretofore
or thereafter issued in accordance with the terms of this Indenture as though
all of such Securities 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
Securities thereafter to be issued as may be appropriate.

          In the event of any such sale or conveyance (other than a conveyance
by way of lease) the Issuer or any successor corporation which shall theretofore
have become such in the manner described in this Article shall be discharged
from all obligations and covenants under this Indenture and the Securities and
may be liquidated and dissolved.

          Section 10.1  Satisfaction and Discharge of Securities of any Series.
                        ------------------------------------------------------  
(A) If at any time (a) the Issuer shall have paid or caused to be paid the
principal of and interest on all the Securities Outstanding hereunder of any
particular series (other than Securities which have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 2.9) as and
when the same shall have become due and payable or (b) the Issuer shall have
delivered to the Trustee for cancellation all Securities of any particular
series theretofore authenticated (other than any Securities which shall have
been destroyed, lost or stolen and which shall have been replaced or paid as
provided in Section 2.9) or (c) in the case of Securities of any particular
series where the exact amount (including the currency of payment) of principal
of and interest due on which can be determined at the time of making the deposit
referred to in clause (ii) below,

               (i)  all the Securities of such series not theretofore delivered
     to the Trustee for cancellation shall

                                       59

 
     have become due and payable, or are by their terms to become due and
     payable within one year or are to be called for redemption within one year
     under arrangements satisfactory to the Trustee for the giving of notice of
     redemption;

               (ii)  the Issuer shall have irrevocably deposited or caused to
     be deposited with the Trustee as trust funds the entire amount in cash
     (other than moneys repaid by the Trustee or any paying agent to the
     Issuer in accordance with Section 10.4) or, in the case of Securities the
     payments on which may only be made in Dollars, direct obligations of the
     United States of America, backed by its full faith and credit ("U.S.
     Government Obligations") maturing as to principal and interest at such
     times and in such amounts as will insure the availability of cash, or a
     combination thereof, in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification
     thereof delivered to the Trustee, to pay, in whole, the principal and
     interest on all Securities of such series on each date that such
     principal or interest is due and payable; and

              (iii)  if, in the case of clause (c), (1) the Issuer shall also
     pay or cause to be paid all other sums payable hereunder by the Issuer; (2)
     such deposit will not result in a breach or violation of, or constitute a
     default under, this Indenture or any agreement or instrument to which the
     Issuer is a party or by which it is bound; (3) the Issuer has delivered to
     the Trustee an Opinion of Counsel based on the fact that (I) the Issuer has
     received from, or there has been published by, the Internal Revenue Service
     a ruling or (II) since the date hereof, there has been a change in the
     applicable Federal income tax law, in either case to the effect that, and
     such opinion shall confirm that, the Holders of the Securities of the
     affected series appertaining thereto will not recognize income, gain or
     loss for Federal income tax purposes as a result of such deposit,
     defeasance and discharge and will be subject to Federal income tax on the
     same amount and in the same manner and at the same times, as would have
     been the case if such deposit defeasance and discharge had not occurred;
     (4) the Issuer has delivered to the Trustee an Officer's Certificate and an
     Opinion of Counsel, each stating that all conditions precedent provided for
     relating to the deposit contemplated by clause (c) of this Section 10.1(A)
     have been complied with; (5) such deposit shall not cause the Trustee to
     have a conflicting interest for purposes of the Trust Indenture Act of 1939
     with respect to any securities of the Issuer; and (6) such deposit shall
     not cause any Securities then listed on any registered national securities
     exchange under the Securities Exchange Act of 1934, as amended, to be
     delisted;

                                       60

 
then the Issuer shall be deemed to have satisfied and discharged the entire
Indebtedness on all the Securities of such series and this Indenture shall cease
to be of further effect with respect to the Securities of such series (except as
to (i) rights of registration of transfer and exchange of Securities and the
Issuer's right of optional redemption, if any, (ii) substitution of mutilated,
defaced, destroyed, lost or stolen Securities, (iii) rights of Holders of
Securities of such series to receive payments of principal thereof and interest
thereon, upon the original stated due dates therefor (but not upon
acceleration), and remaining rights of the Holders to receive mandatory sinking
fund payments, if any, (iv) the rights, obligations, duties and immunities of
the Trustee hereunder, (v) the rights of the Holders of Securities of such
series as beneficiaries hereof with respect to the property so deposited with
the Trustee payable to all or any of them, and (vi) the obligations of the
Issuer under Section 3.2) and, so long as no Event of Default shall be
continuing, the Trustee, on demand of the Issuer accompanied by an Officer's
Certificate and an Opinion of Counsel which comply with Section 11.5 and at the
reasonable cost and expense of the Issuer, shall execute proper instruments
acknowledging such satisfaction and discharging of this Indenture with respect
to the Securities of the affected series; provided that the rights of Holders of
                                          --------                              
the Securities of such series to receive amounts in respect of principal of and
interest on the Securities held by them shall not be delayed longer than
required by then-applicable mandatory rules or policies of any securities
exchange upon which such Securities are listed.  The Issuer agrees to reimburse
the Trustee for any reasonable costs or expenses (including, without limitation,
reasonable fees and expenses of counsel) thereafter reasonably and properly
incurred and to compensate the Trustee for any services thereafter reasonably
and properly rendered by the Trustee in connection with this Indenture or the
Securities.

          Notwithstanding the satisfaction and discharge of this Indenture, (i)
any obligations of the Issuer under Sections 2.8 (other than the first paragraph
of Section 2.8), 2.9, 2.11, 3.2, 4.1 and 6.9 shall survive for a period of three
years after the date upon which principal and interest on such series of
Securities shall have been paid (provided such three year period will not
include such time as the Trustee or any paying agent is unable to apply any
money by reason of any order or judgment of any court or government authority as
described in Section 10.7) and (ii) any obligations of the Issuer to the Trustee
under Sections 6.6 and 11.12 and the first paragraph of Section 2.8 and the
obligations of the Issuer and the Trustee for any series of Securities under
Article 10 and any rights of the Holders of the Securities under Section 10.5
shall survive.

          (B)   The Issuer shall be released from its obligations under
Sections 3.6, 3.7, 3.8, 3.9 and 3.10 with respect to the

                                       61

 
Securities of any particular series Outstanding on and after the date the
conditions set forth below are satisfied (hereinafter, "covenant defeasance").
For this purpose, such covenant defeasance means that, with respect to the
Outstanding Securities of the affected series, the Issuer may omit to comply
with and shall have no liability in respect of any term, condition or limitation
set forth in such Sections, whether directly or indirectly by reason of any
reference elsewhere herein to such Sections or by reason of any reference in
such Sections to any other provision herein or in any other document and such
omission to comply shall not constitute an Event of Default with respect to such
series of Securities under Section 5.1, but the remainder of this Indenture and
such Securities shall be unaffected thereby.  The following shall be the
conditions to application of this subsection (B) of this Section 10.1:

               (a)  The Issuer has irrevocably deposited or caused to be
     deposited with the Trustee as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the holders of the Securities of the
     affected series, (i) cash in an amount, or (ii) in the case of Securities
     the payments on which may only be made in Dollars, U.S. Government
     Obligations maturing as to principal and interest at such times and in such
     amounts as will insure the availability of cash or (iii) a combination
     thereof, sufficient, in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee, to pay, in whole, the principal and interest on
     all Securities of the affected series.

               (b)  No Event of Default or event which with notice or lapse of
     time or both would become an Event of Default with respect to the
     Securities of the affected series shall have occurred and be continuing on
     the date of such deposit or, insofar as subsections 5.1(f) and (g) are
     concerned, at any time during the period ending on the 91st day after the
     date of such deposit (it being understood that this condition shall not be
     deemed satisfied until the expiration of such period).

               (c)  Such covenant defeasance shall not cause the Trustee to have
     a conflicting interest for purposes of the Trust Indenture Act of 1939 with
     respect to any securities of the Issuer.

               (d)  Such covenant defeasance shall not result in a breach or
     violation of, or constitute a default under, this Indenture or any other
     agreement or instrument to which the Issuer is a party or by which it is
     bound.

                                       62

 
               (e) Such covenant defeasance shall not cause any Securities then
     listed on any registered national securities exchange under the Securities
     Exchange Act of 1934, as amended, to be delisted.

               (f)  The Issuer shall have delivered to the Trustee an Officer's
     Certificate and Opinion of Counsel to the effect that the Holders of the
     Securities of the affected series will not recognize income, gain or loss
     for Federal income tax purposes as a result of such covenant defeasance and
     will be subject to Federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such covenant
     defeasance had not occurred.

               (g)  The Issuer shall have delivered to the Trustee an Officer's
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for relating to the covenant defeasance contemplated by
     this provision have been complied with.

          Section 10.2  Satisfaction and Discharge of Indenture.  Upon
                        ---------------------------------------       
compliance by the Issuer with the provisions of Section 10.1(A) as to the
satisfaction and discharge of each series of Securities issued hereunder, and if
the Issuer has paid or caused to be paid all other sums payable under this
Indenture, this Indenture shall cease to be of any further effect (except as
otherwise provided herein).  Upon Issuer Order and receipt of an Opinion of
Counsel and an Officer's Certificate, stating that all conditions precedent
provided for in this Indenture relating to such proposed action have been
complied with, the Trustees for all series of Securities (at the expense of the
Issuer) shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture.

          Notwithstanding the satisfaction and discharge of this Indenture, (i)
any obligations of the Issuer under Sections 2.8 (other than the first paragraph
of Section 2.8), 2.9, 2.11, 3.2, 4.1 and 6.9 shall survive for a period of three
years after the date upon which principal and interest on such series of
Securities shall have been paid (provided such three year period will not
include such time as the Trustee or any paying agent is unable to apply any
money by reason of any order or judgment of any court or government authority as
described in Section 10.7) and (ii) any obligations of the Issuer to the Trustee
under Sections 6.6 and 11.12 and the first paragraph of Section 2.8 and the
obligations of the Issuer and the Trustee for any series of Securities under
Article 10 and any rights of the Holders of the Securities under Section 10.5
shall survive.

          Section 10.3  Application by Trustee of Funds Deposited for Payment of
                        --------------------------------------------------------
Securities.  Subject to Section 10.4, all moneys deposited with the Trustee
- ----------                                                                 
pursuant to Section 10.1 shall be held in trust and applied by it to the payment
to the Holders of the particular Securities 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 and interest; but such money need not be
segregated from other funds except to the extent required by law.

          Section 10.4  Repayment of Moneys Held by Paying Agent.  In connection
                        ----------------------------------------                
with the satisfaction and discharge of this Indenture with respect to all
Securities issued hereunder, all moneys then held by any paying agent under the
provisions of this Indenture shall, upon demand of the Issuer, be repaid to it
or paid to the Trustee and thereupon such paying agent shall be released from
all further liability with respect to such moneys.

          Section 10.5  Return of Moneys Held by Trustee and Paying Agent
                        -------------------------------------------------
Unclaimed for Two Years.  Any moneys deposited with or paid to the Trustee or
- -----------------------                                                      
any paying agent for the payment of the principal of or interest on any Security
and not applied but remaining unclaimed for two years after the date upon which
such principal or interest shall have become due and payable (provided such two
year period will not include such time as the Trustee or any paying agent is
unable to apply any money by reason of any order or judgment of any court or
government authority as described in Section 10.7), shall, upon the written
request of the Issuer and unless otherwise required by mandatory provisions of
applicable escheat or abandoned or unclaimed property law, be repaid to the
Issuer by the Trustee or such paying agent, and the Holder of the Securities
shall be entitled thereafter to look only to the Issuer (subject to applicable
escheat or abandoned property or unclaimed property law) with respect to any
payment which such Holder may be entitled to collect hereunder, and all
liability of the Trustee or any paying agent with respect to such moneys shall
thereupon cease; provided, however, that the Trustee or such paying agent,
                 --------  -------                                        
before being required to make any such repayment with respect to moneys
deposited with it for any payment in respect of Securities, shall at the expense
of the Issuer, mail by first-class mail to Holders of such affected Securities
at their addresses as they shall appear on the Security register, notice that
such moneys remain and that, after a date specified therein, which shall not be
less than 30 days from the date of such mailing or publication, any unclaimed
balance of such money then remaining will be repaid to the Issuer.

          Notwithstanding any provision to the contrary in this Section 10.5 the
Issuer shall not take any action under this Section 10.5 with respect to the
Securities of any series which

                                       64

 
is in violation of the rules or requirements of any stock exchange on which the
Securities of such series are listed.

          Section 10.6  Indemnity for U.S. Government Obligations.  The Issuer
                        -----------------------------------------             
shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to
Section 10.1 or the principal or interest received in respect of such
Obligations.

          Section 10.7  Reinstatement Provision.  If the Trustee or any paying
                        -----------------------                               
agent is unable to apply any money in accordance with this Article 10 by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application then the Issuer's
obligations under this Indenture and the Securities of the affected series shall
be revived and reinstated as though no deposit had occurred pursuant to Section
10.1 until such time as the Trustee or such paying agent is permitted to apply
all such money in accordance with Section 10.2; provided, however, that if the
                                                --------  -------             
Issuer makes any payment of interest on or principal of any Security of the
affected series following the reinstatement of its obligations, the Issuer shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money held by the Trustee or such paying agent.

any incorporator, as such, or against any past, present or future stockholder,
officer or director, as such, of the Issuer or of any successor, either directly
or through the Issuer or any successor, under rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities by the Holders thereof and as
part of the consideration for the issue of the Securities.

          Section 11.2  Provisions of Indenture for the Sole Benefit of Parties

                        ---------------------------------------------------  
All the covenants, stipulations, promises and agreements in this Indenture
contained by or on behalf of the Issuer shall bind its successors and assigns,
whether so expressed or not.

          Section 11.4  Notices and Demands on Issuer, Trustee and Holders of
                        -----------------------------------------------------
Securities.  Any notice or demand which by any provision of this Indenture is
- ----------                                                                   
required or permitted to be given or served by the Trustee or by the Holders of
Securities to or on the Issuer may be given or served by being deposited postage
prepaid, first-class mail (except as otherwise specifically provided herein)
addressed (until another address of the Issuer is filed by the Issuer with the
Trustee) to P. H. Glatfelter Company, 228 South Main Street, Spring Grove,
Pennsylvania 17362, Attention:  Secretary.  Any notice, direction, request or
demand by the Issuer or any Holder of Securities to or upon the Trustee shall be
deemed to have been sufficiently given or served by being deposited postage
prepaid, first-class mail (except as otherwise specifically provided herein)
addressed (until another address of the Trustee is filed by the Trustee with the
Issuer) to Wachovia Bank of Georgia, N.A., 191 Peachtree Street, Twenty-Second

          Notice to Holders of Securities shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to each Holder entitled thereto, at his last address as it
appears in the Security register.  In any case where notice to such Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.

          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, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

          In case, by reason of the suspension of or irregularities in regular
mail service, it shall be impracticable

                                       66

 
to mail notice to the Issuer when such notice is required to be given pursuant
to any provision of this Indenture, then any manner of giving such notice as
shall be reasonably satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice.

Issuer to the Trustee to take any action under any of the provisions of this
Indenture or any supplemental indenture, the Issuer shall furnish to the Trustee
an Officer's Certificate stating that all conditions precedent provided for in
this Indenture relating to the proposed action have been complied with and an
Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent have been complied with, except that in the case of any
such application or demand as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such
particular application or demand, no additional certificate or opinion need be
furnished.

          Each certificate 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 (a) a statement that the person
giving such certificate or opinion has read such covenant or condition, (b) a
brief statement as to the nature and scope of the examination or investigation
upon which the statements or opinions contained in such certificate or opinion
are based, (c) a statement that, in the opinion of such person, he has made such

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 erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

          Section 11.11  Securities in a Foreign Currency or in ECU.  Unless
                         ------------------------------------------         
otherwise specified in an Officer's Certificate delivered pursuant to Section
2.3 of this Indenture with respect to the Securities, whenever for purposes of
this Indenture any action may be taken by the Holders of a specified percentage
in aggregate principal amount of the Securities and, at such time, there are
Outstanding Securities which are denominated in a coin or currency other than
Dollars (including ECUs), then the principal amount of Securities which shall be
deemed to be Outstanding for the purpose of taking such action shall be that
amount of Dollars that could be obtained for such amount at the Market Exchange
Rate.  For purposes of this Section 11.11, Market Exchange Rate shall mean the
noon Dollar buying rate in New York City for cable transfers of that currency as
published by the Federal Reserve Bank of New York; provided, however, in the
                                                   --------  -------        
case of ECUs, Market Exchange Rate shall mean the rate of exchange determined by
the Commission of the European Communities (or any successor thereto) as
published in the Official Journal of the European Communities (such publication
or any successor publication, the "Journal").  If such Market Exchange Rate is
not available for any reason with respect to such currency, the Trustee shall
use, in its sole discretion and without liability on its part, such quotation of
the Federal Reserve Bank of New York or, in the case of ECUs, the rate of
exchange as published in the Journal, as of the most recent available date, or
quotations or, in the case of ECUs, rates of exchange from one or more major
banks in the City of New York or in the country of issue of the currency in
question, which for purposes of the ECU shall be Brussels, Belgium, or such
other quotations or, in the case of ECUs, rates of exchange as the Trustee shall
deem appropriate.  The provisions of this paragraph shall apply in determining
the equivalent principal amount in respect of Securities denominated in a
currency other than Dollars in connection with any action taken by Holders of
Securities pursuant to the terms of this Indenture.

          All decisions and determinations of the Trustee regarding the Market
Exchange Rate or any alternative determination provided for in the preceding
paragraph shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding on the Issuer and all Holders.

          Section 11.12  Judgment Currency.  The Issuer agrees to the fullest
                         -----------------                                   
extent that it may effectively do so under applicable law, that (a) if for the
purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of or interest on the Securities (the "Required
Currency") into a currency in which a judgment will be rendered (the "Judgment
Currency") the rate of exchange used shall be the rate at which in accordance
with normal banking procedures the

                                       69

 
Trustee could purchase in the City of New York the Required Currency with the
Judgment Currency on the day on which final unappealable judgment is entered,
unless such day is not a New York Banking Day, then, to the extent permitted by
applicable law, the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in the City
of New York the Required Currency with the Judgment Currency on the New York
Banking Day preceding the day on which final unappealable judgment is entered
and (b) its obligations under this Indenture to make payments in the Required
Currency (i) shall not be discharged or satisfied by any tender, or any recovery
pursuant to any judgment (whether or not entered in accordance with subsection
(a)), in any currency other than the Required Currency, except to the extent
that such tender or recovery shall result in the actual receipt, by the payee,
of the full amount of the Required Currency expressed to be payable in respect
of such payments, (ii) shall be enforceable as an alternative or additional
cause of action for the purpose of recovering in the Required Currency the
amount, if any, by which such actual receipt shall fall short of the full amount
of the Required Currency so expressed to be payable and (iii) shall not be
affected by judgment being obtained for and other sum due under this Indenture.
For purposes of the forgoing, "New York Banking Day" means any day except a
Saturday, Sunday or a legal holiday in the City of New York or a day on which
banking institutions in the City of New York are authorized or required by law
or executive order to close.
