determines that such action may not lawfully be taken or if the Trustee in good
faith by its board of directors or trustees, executive committee, or a trust
committee of directors or trustees and/or vice presidents shall determine that
such action would expose the Trustee to personal liability to existing holders.

SECTION 2.5  Date and Denomination of Securities.

     The Securities shall be issuable in such form and in such denominations as
shall be specified as contemplated by Section 2.2.  In the absence of any such
specification with respect to the Securities of any series, the Securities of
such Series shall be issuable as registered Securities without coupons and in

numbered, lettered, or otherwise distinguished in such manner or in accordance
with such plans as the officers of the Company executing the same may determine
with the approval of the Trustee as evidenced by the execution and

interest, if any, from such date and shall be payable on such dates, in each
case, as contemplated by Section 2.2.  The interest installment on any Security

Payment Date for Securities of that series shall be paid to the Person in whose
name said Security (or one or more Predecessor Securities) is registered at the
close of business on the regular record date for such interest installment. In
the event that any Security of a particular series or portion thereof is called
for redemption and the redemption date is subsequent to a regular record date
with respect to any Interest Payment Date and prior to such Interest Payment
Date, interest on such Security will be paid upon presentation and surrender of
such Security as provided in Section 3.1.

     Any interest on any Security that is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date for any Security of the same
series (herein called "Defaulted Interest") shall forthwith cease to be payable
to the registered holder on the relevant regular record date by virtue of having
been such holder, and such Defaulted Interest shall be paid by the Company, at
its election, as provided in clause (a) or clause (b) below:

     (a) The Company may make payment of any Defaulted Interest on Securities to
the Persons in whose names such Securities (or their respective Predecessor
Securities) are registered at the close of business on a special record date for
the payment of such Defaulted Interest, which shall be fixed in the following
manner: the Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each such Security and the date of the
proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit prior to the date of the proposed payment, such
money when deposited to be held in trust for the benefit of the Persons entitled
to such Defaulted Interest as in this clause provided. Thereupon the Trustee
shall fix a special record date for the payment of such Defaulted Interest which
shall not be more than 15 nor less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such special record date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the special record date therefor to be mailed, first class postage prepaid,
to each Securityholder at his or her address as it appears in the Security
Register, not less than 10 days prior to such special record date. Notice of the
proposed payment of such Defaulted Interest and the special record date therefor
having been mailed as aforesaid, such Defaulted Interest shall be paid to the
Persons in whose names such Securities (or their respective Predecessor
Securities) are registered on such special record date and shall be no longer
payable pursuant to the following clause (b).

     (b) The Company may make payment of any Defaulted Interest on any
Securities in any other lawful manner not inconsistent with the requirements of
any securities exchange on which such Securities may be listed, and upon such
notice as may be required by such exchange, if, after notice given by the
Company to the Trustees of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

     Unless otherwise set forth in a Board Resolution of the Company or one or
more indentures supplemental hereto establishing the terms of any series of
Securities pursuant to Section 2.2 hereof, the term "regular record date" as
used in this Section with respect to a series of Securities with respect to any
Interest Payment Date for such series

<PAGE>

shall mean either the fifteenth day of the month in which an Interest Payment
Date established for such series pursuant to Section 2.2 hereof shall occur, if
such Interest Payment Date is the last day of a month, or the last day of the
month immediately preceding the month in which an Interest Payment Date
established for such series pursuant to Section 2.2 hereof shall occur, if such
Interest Payment Date is the fifteenth day of a month, whether or not such date
is a Business Day.

     Subject to the foregoing provisions of this Section, each Security of a
series delivered under this Indenture upon transfer of or in exchange for or in
lieu of any other Security of such series shall carry the rights to interest
accrued and unpaid, and to accrue, that were carried by such other Security.

SECTION 2.6  Transfer and Exchange.

     Subject to Section 2.2(m), Securities of any series may be exchanged for a
like aggregate principal amount of Securities of the same series of other
authorized denominations. Securities to be exchanged may be surrendered at the
principal office of the Trustee or at any office or agency to be maintained by
the Company for such purpose as provided in Section 3.2, and the Company or the
Trustee shall execute and register and the Trustee or the Authenticating Agent
shall authenticate and deliver in exchange therefor the Security or Securities
which the Securityholder making the exchange shall be entitled to receive. Upon
due presentment for registration of transfer of any Security of any series at
the principal office of the Trustee or at any office or agency of the Company
maintained for such purpose as provided in Section 3.2, the Company or the
Trustee shall execute and register and the Trustee or the Authenticating Agent
shall authenticate and deliver in the name of the transferee or transferees a
new Security or Securities of the same series for a like aggregate principal
amount. Registration or registration of transfer of any Security by the Trustee
or by any agent of the Company appointed pursuant to Section 3.2, and delivery
of such Security, shall be deemed to complete the registration or registration
of transfer of such Security.

     The Company shall cause to be kept at the corporate trust office of the
Trustee a register in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities.  Such register is herein sometimes referred to as the
"Securities Register."

     To permit registrations of transfers and exchanges, the Company shall
execute and the Trustee, upon receipt of a Company Order, shall authenticate
Definitive Securities and Global Securities at the Security Registrar's request.
All Definitive Securities and Global Securities issued upon any registration of
transfer or exchange of Definitive Securities or Global Securities shall be the
valid obligations of the Company, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Definitive Securities or Global
Securities surrendered upon such registration of transfer or exchange.

     Upon surrender for registration of transfer of any Security at the office
or agency of the Company designated for that purpose the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of the same series of any
authorized denominations, of a like aggregate principal amount, of the same
original same issue date and Stated Maturity Date and having the same terms.

     No service charge shall be made to a holder for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith.

     The Company shall not be required to (i) issue, register the transfer of or
exchange Securities during a period beginning at the opening of business 15 days
before the day of mailing of a notice of redemption or any notice of selection
of Securities of such series for redemption; or (ii) register the transfer of or
exchange any Security of such series so selected for redemption in whole or in
part, except the unredeemed portion of any Security of such series being
redeemed in part.

     Prior to due presentment for the registration of a transfer of any
Security, the Trustee, the Company and any agent of the Trustee or the Company
may deem and treat the Person in whose name any Security is registered as the
absolute owner of such Security for the purpose of receiving payment of
principal of and premium, if any, and

                                      10
<PAGE>

interest on such Securities, and for all other purposes whatsoever, and none of
the Trustee, the Company and any agents of the Trustee or the Company shall be
affected by notice to the contrary.
SECTION 2.7  Replacement Securities.

     If any mutilated Security is surrendered to the Trustee, or the Company and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Security, the Company shall issue and the Trustee shall
authenticate a replacement Security if the Trustee's requirements for
replacements of Securities are met.  An indemnity bond must be supplied by the
holder that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee, any agent thereof or any authenticating agent
from any loss that any of them may suffer if a Security is replaced.  The
Company or the Trustee may charge for its expenses in replacing a Security.

     Every replacement Security is an obligation of the Company and shall be
entitled to all of the benefits of this Indenture equally and proportionately
with all other Securities duly issued hereunder.

SECTION 2.8  Temporary Securities.

     Pending the preparation of Definitive Securities, the Company may execute,
and upon Company Order the Trustee shall authenticate and make available for
delivery, temporary Securities that are printed, lithographed, typewritten,
mimeographed or otherwise reproduced, in any authorized denomination,
substantially of the tenor of the Definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities.

     If temporary Securities are issued, the Company shall cause Definitive
Securities to be prepared without unreasonable delay.  The Definitive Securities
shall be printed, lithographed or engraved, or provided by any combination
thereof, or in any other manner permitted by the rules and regulations of any
applicable securities exchange, all as determined by the officers executing such
Definitive Securities.  After the preparation of Definitive Securities, the
temporary Securities shall be exchangeable for Definitive Securities upon
surrender of the temporary Securities at the office or agency maintained by the
Company for such purpose pursuant to Section 3.2 hereof, without charge to the
Holder.  Upon surrender for cancellation of anyone or more temporary Securities,
the Company shall execute, and the Trustee shall authenticate and make available
for delivery, in exchange therefor the same aggregate principal amount of
Definitive Securities of authorized denominations.  Until so exchanged, the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as Definitive Securities.

SECTION 2.9   Cancellation.

     The Company at any time may deliver Securities to the Trustee for
cancellation.  The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall retain or destroy cancelled Securities in accordance with
its normal practices (subject to the record retention requirement of the
Exchange Act) unless the Company directs that they be returned to it. Subject to
Sections 2.6 and 2.7, the Company may not issue new Securities to replace
Securities that have been redeemed or paid or that have been delivered to the
Trustee for cancellation.

SECTION 2.10  Global Securities.

     (a) If the Company shall establish pursuant to Section 2.2 that the
Securities of a particular series are to be issued as a Global Security, then
the Company shall execute and the Trustee shall, in accordance with Section 2.4,
authenticate and deliver, a Global Security that (i) shall represent, and shall
be denominated in an amount equal to the aggregate principal amount of, all of
the outstanding Securities of such series, (ii) shall be registered in the name
of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instruction and (iv) shall bear a
legend substantially to the following effect: "Except as otherwise provided in
Section 2.10 of the Indenture, this Security may be transferred, in whole but
not in part, only to another nominee of the Depositary or to a successor
Depositary or to a nominee of such successor Depositary."

                                      11
<PAGE>

     (b) Notwithstanding the provisions of Section 2.6, the Global Security of a
series may be transferred, in whole but not in part and in the manner provided
in Section 2.6, only to another nominee of the Depositary for such series or to
a successor Depositary for such series selected or approved by the Company or to
a nominee of such successor Depositary.

     (c) If at any time the Depositary for a series of the Securities notifies
the Company that it is unwilling or unable to continue as Depositary for such
series or if at any time the Depositary for such series shall no longer be
registered or in good standing under the Exchange Act, or other applicable
statute or regulation, and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, this Section 2.10 shall
no longer be applicable to the Securities of such series and the Company will
execute, and subject to Section 2.6, the Trustee will authenticate and deliver,
the Definitive Securities of such series, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Security
of such series in exchange for such Global Security. In addition, the Company
may at any time determine that the Securities of any series shall no longer be
represented by a Global Security and that the provisions of this Section 2.10
shall no longer apply to the Securities of such series. In such event the
Company will execute and, subject to Section 2.6, the Trustee, upon receipt of
an Officers' Certificate evidencing such determination by the Company, will
authenticate and deliver the Definitive Securities of such series, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security of such series in exchange for such Global
Security. Upon the exchange of the Global Security for such Definitive
Securities, in authorized denominations, the Global Security shall be cancelled
by the Trustee. Such Definitive Securities issued in exchange for the Global
Security pursuant to this Section 2.10(c) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. The Trustee shall deliver such Definitive Securities to the Depositary
for delivery to the Persons in whose names such Definitive Securities are so
registered.

SECTION 2.11  CUSIP Numbers.

     The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Securityholders; 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 in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.  The Company will promptly notify
the Trustee of any change in the CUSIP numbers.

                                  ARTICLE III

                      PARTICULAR COVENANTS OF THE COMPANY

SECTION 3.1   Payment of Principal and Interest.

     The Company covenants and agrees for the benefit of each series of the
Securities that it will duly and punctually pay or cause to be paid the
principal of and interest on each series of the Securities at the place, at the
respective times and in the manner provided herein. Each installment of interest
on the Securities of any series may be paid by (i) mailing checks for such
interest payable to the order of the holder of Security entitled thereto as they
appear in the Security Register, or (ii) by wire transfer to an account
appropriately designated by the Holder entitled thereto, provided that proper
transfer instructions have been received in writing by the relevant record date.

SECTION 3.2   Offices for Notices and Payments, etc.

     So long as any of the Securities remain outstanding, the Company will
maintain in the Borough of Manhattan, The City of New York, an office or agency
where the Securities of each series may be presented for payment, an office or
agency where the Securities of that series may be presented for registration of
transfer and for exchange as in this Indenture provided and an office or agency
where notices and demands to or upon the Company in respect of the Securities of
that series or of this Indenture may be served.  The Company will give to the
Trustee written notice of the location of any such office or agency and of any
change of location thereof.  Until otherwise designated from time to time by the
Company in a notice to the Trustee or specified as contemplated by Section 2.2,
any such office or agency for all of the above purposes shall be the Principal
Office of the Trustee.  In case the

                                      12
<PAGE>

Company shall fail to maintain any such office or agency 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 thereof, presentations and demands may
be made and notices may be served at the Principal Office of the Trustee.

     In addition to any such office or agency, the Company may from time to time
designate one or more offices or agencies outside the Borough of Manhattan, The
City of New York, where the Securities may be presented for payment,
registration of transfer and for exchange in the manner provided in this
Indenture, and the Company may from time to time rescind such designation, as
the Company may deem desirable or expedient; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain any such office or agency in the Borough of Manhattan,
The City of New York, for the purposes above mentioned.  The Company will give
to the Trustee prompt written notice of any such designation or rescission
thereof.

SECTION 3.3  Appointments to Fill Vacancies in Trustee's Office.

     The Company, whenever necessary to avoid or fill a vacancy in the office of
Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so
that there shall at all times be a Trustee hereunder.

SECTION 3.4  Provision as to Paying Agent.

     (a) If the Company shall appoint a paying agent other than the Trustee with
respect to the Securities of any series, 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 provision of this Section 3.4,

        (1) that it will hold all sums held by it as such agent for the payment
     of the principal of or interest on the Securities of such series (whether
     such sums have been paid to it by the Company or by any other obligor on
     the Securities of such series) in trust for the benefit of the holders of
     the Securities; and

        (2) that it will give the Trustee notice of any failure by the Company
     (or by any other obligor on the Securities of such series) to make any
     payment of the principal of or interest on the Securities of such series
     when the same shall be due and payable.

     (b) If the Company shall act as its own paying agent, it will, on or before
each due date of the principal of or interest on the Securities of any series,
set aside, segregate and hold in trust for the benefit of the holders of the
Securities of such series a sum sufficient to pay such principal or interest so
becoming due and will notify the Trustee of any failure to take such action and
of any failure by the Company (or by any other obligor under the Securities of
such series) to make any payment of the principal of or interest on the
Securities of such series when the same shall become due and payable.

     (c) Anything in this Section 3.4 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge with respect to one or more or all series of Securities hereunder, or
for any other reason, pay or cause to be paid to the Trustee all sums held in
trust for any such series by the Trustee or any paying agent hereunder, as
required by this Section 3.4, such sums to be held by the Trustee upon the
trusts herein contained.

     (d) Anything in this Section 3.4 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 3.4 is subject to
Section 11.3 and Section 11.4.

SECTION 3.5   Certificate to Trustee.

     The Company will deliver to the Trustee on or before 120 days after the end
of each fiscal year in each year, commencing with the first fiscal year in which
there shall be issued any of the issuance of Securities of any series under this
Indenture, so long as Securities of any series are outstanding hereunder, an
Officers' Certificate, one of the signers of which shall be the principal
executive, principal financial or principal accounting officer of the Company,
stating that in the course of the performance by the signers of their duties as
officers of the Company they would normally have knowledge of

                                      13
<PAGE>

any default by the Company in the performance of any covenants contained herein,
stating whether or not they have knowledge of any such default and, if so,
specifying each such default of which the signers have knowledge and the nature
thereof.

SECTION 3.6   Compliance with Consolidation Provisions.

     The Company will not, while any of the Securities remain outstanding,
consolidate with, or merge into, or merge into itself, or sell or convey all or
substantially all of its property to any other Person unless the provisions of
Article X hereof are complied with.

SECTION 3.7   Limitation on Dividends.

     The Company will not: (i) declare or pay any dividends or distributions on,
or redeem, purchase, acquire, or make a liquidation payment with respect to, any
of the Company's capital stock (which includes common and preferred stock)
(other than (a) dividends or distributions in shares of, or options, warrants or
rights to subscribe for or purchase shares of, Common Stock of the Company, (b)
any declaration of a dividend in connection with the implementation of a
stockholder's rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
as a result of a reclassification of any class or series of the Company's
capital stock solely into another class or series of the Company's capital
stock, (d) the purchase of fractional shares resulting from such
reclassification or pursuant to the conversion or exchange provisions of such
capital stock or any security convertible or exchangeable into shares of the
Company's capital stock, and (e) purchases of Common Stock related to the
issuance of Common Stock or rights under any of the Company's benefit plans for
its directors, officers or employees or any of the Company's dividend
reinvestment plans); (ii) make any payment of principal, premium, if any, or
interest on or repay or repurchase or redeem any debt securities of the Company
(including Other Debentures) that rank pari passu with or junior in right of
payment to the Securities; or (iii) make any guarantee payments (other than
payments under the Preferred Securities Guarantee) with respect to any guarantee
by the Company of the debt securities of any Subsidiary of the Company
(including Other Guarantees) if such guarantee ranks pari passu or junior in
right of payment to the Securities, if at such time (1) there shall have
occurred any event of which the Company has actual knowledge that (a) is, or
with the giving of notice or the lapse of time, or both, would constitute, an
Event of Default and (b) in respect of which the Company shall not have taken
reasonable steps to cure, or (2) if such Securities are held by the Property
Trustee, the Company shall be in default with respect to its payment obligations
under the Preferred Securities Guarantee.

SECTION 3.8   Covenants as to Sterling Capital Trusts.

     In the event Securities are issued to a Sterling Capital Trust or a trustee
of such trust in connection with the issuance of Trust Securities by such
Sterling Capital Trust, for so long as such Trust Securities remain outstanding,
the Company: (i) will maintain 100% direct or indirect ownership of the Common
Securities of such Sterling Capital Trust; provided, however, that any successor
of the Company, permitted pursuant to Article X, may succeed to the Company's
ownership of such Common Securities; (ii) use its reasonable efforts not to
voluntarily terminate, wind up or liquidate such Sterling Capital Trust except
with the prior approval of the Federal Reserve if then so required under
applicable capital guidelines or policies of the Federal Reserve, and except (a)
in connection with a distribution of Junior Subordinated Debentures to the
holders of the Trust Preferred Securities in liquidation of such Sterling
Capital Trust or (b) in connection with certain mergers, consolidations, or
amalgamations permitted by the Declaration of such Sterling Capital Trust; (iii)
will use its reasonable efforts to cause such Sterling Capital Trust (a) to
remain a business trust, except in connection with a distribution of Securities
to the holders of Trust Securities in liquidation of such Sterling Capital
Trust, the redemption of all of the Trust Securities of such Sterling Capital
Trust or certain mergers, consolidations or amalgamations, each as permitted by
the Declaration of such Sterling Capital Trust, and (b) to otherwise continue to
be treated as a grantor trust for United States Federal income tax purposes; and
(iv) will use its reasonable efforts to cause each holder of the Trust
Securities of such Sterling Capital Trust to be treated as owning an undivided
beneficial interest in the Securities.

                                  ARTICLE IV

       SECURITYHOLDERS' LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

SECTION 4.1   Securityholders' Lists.

     The Company covenants and agrees that it will furnish or cause to be
furnished to the Trustee:

     (a) on a semi-annual basis on each regular record date for each series of
Securities, a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Securityholders of such series of Securities as of
such record date; and

     (b) at such other times as the Trustee may request in writing, within 30
days after the receipt by the Company, of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished, except that, no such lists need be furnished so long as the
Trustee is in possession thereof by reason of its acting as Security registrar
of such series.

SECTION 4.2   Preservation and Disclosure of Lists.

     (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the holders of
each series of Securities (1) contained in the most recent list furnished to it
as provided in Section 4.1 or (2) received by it in the capacity of Securities
registrar (if so acting) hereunder. The Trustee may destroy any list furnished
to it as provided in Section 4.1 upon receipt of a new list so furnished.

     (b) In case three or more holders of Securities of any series (hereinafter
referred to as "applicants") apply in writing to the Trustee and furnish to the
Trustee reasonable proof that each such applicant has owned a Security of such
series for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other holders of Securities of such series or with holders of
all Securities with respect to their rights under this Indenture and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall within 5 Business Days
after the receipt of such application, at its election, either:

        (1) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with the provisions of subsection (a) of
     this Section 4.2, or

        (2) inform such applicants as to the approximate number of holders of
     such series or all Securities, as the case may be, whose names and
     addresses appear in the information preserved at the time by the Trustee in
     accordance with the provisions of subsection (a) of this Section 4.2, and
     as to the approximate cost of mailing to such Securityholders the form of
     proxy or other communication, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Securityholder of such series or all Securities, as the case may
be, whose name and address appear in the information preserved at the time by
the Trustee in accordance with the provisions of subsection (a) of this Section
4.2 a copy of the form of proxy or other communication which is specified in
such request with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interests of the holders of Securities of such series or all Securities, as the
case may be, or would be in violation of applicable law.  Such written statement
shall specify the basis of such opinion.  If the Commission, after opportunity
for a hearing upon the objections specified in the written statement so filed,
shall enter an order refusing to sustain any of such objections or if, after the
entry of an order sustaining one or more of such objections, the

                                      15
<PAGE>

Commission shall find, after notice and opportunity for hearing, that all the
objections so sustained have been met and shall enter an order so declaring, the
Trustee shall mail copies of such material to all such Securityholders with
reasonable promptness after the entry of such order and the renewal of such
tender; otherwise the Trustee shall be relieved of any obligation or duty to
such applicants respecting their application.

     (c) Each and every holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any paying agent shall be held accountable by reason of the disclosure of
any such information as to the names and addresses of the holders of Securities
in accordance with the provisions of subsection (b) of this Section 4.2,
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under said subsection (b).

SECTION 4.3   Reports by the Company.

     (a) The Company covenants and agrees to file with the Trustee, within 15
days after the date on which the Company is required to file the same with the
Commission, copies of the annual reports and of the information, documents and
other reports (or copies of such portions of any of the foregoing as said
Commission may from time to time by rules and regulations prescribe) which the
Company may be required to file with the Commission pursuant to Section 13 or
Section 15(d) of the Exchange Act; or, if the Company is not required to file
information, documents or reports pursuant to either of such sections, then to
file with the Trustee and the Commission, in accordance with rules and
regulations prescribed from time to time by the Commission, such of the
supplementary and periodic information, documents and reports which may be
required pursuant to Section 13 of the Exchange Act in respect of a security
listed and registered on a national securities exchange as may be prescribed
from time to time in such rules and regulations.

     (b) The Company covenants and agrees to file with the Trustee and the
Commission, in accordance with the rules and regulations prescribed from time to
time by said Commission, such additional information, documents and reports with
respect to compliance by the Company with the conditions and covenants provided
for in this Indenture as may be required from time to time by such rules and
regulations.

     (c) The Company covenants and agrees to transmit by mail to all holders of
Securities, as the names and addresses of such holders appear upon the Security
Register, within 30 days after the filing thereof with the Trustee, such
summaries of any information, documents and reports required to be filed by the
Company pursuant to subsections (a) and (b) of this Section 4.3 as may be
required by rules and regulations prescribed from time to time by the
Commission.

     (d) Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

SECTION 4.4   Reports by the Trustee.

     (a) The Trustee shall transmit to Securityholders such reports concerning
the Trustee and its actions under this Indenture as may be required pursuant to
the Trust Indenture Act at the times and in the manner provided pursuant
thereto. If required by Section 313(a) of the Trust Indenture Act, the Trustee
shall, within sixty days after each June 6 following the date of this Indenture,
commencing June 6, deliver to Securityholders a brief report, dated as of such
September 15, which complies with the provisions of such Section 313(a).

     (b) A copy of each such report shall, at the time of such transmission to
Securityholders, be filed by the Trustee with each stock exchange, if any, upon
which the Securities are listed, with the Commission and with the Company. The
Company will promptly notify the Trustee when the Securities are listed on any
stock exchange.

                                   ARTICLE V

        REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

SECTION 5.1   Events of Default.

     Unless otherwise provided with respect to a series of the Securities in the
indenture supplemental hereto providing for the creation of that series, each
one or more of the following events of default shall constitute an Event of
Default with respect to Securities of such series, as shall any other events as
may be established with respect to Securities of that series as contemplated by
Section 2.2 (whatever the reason for such Event of Default and whether it shall
be voluntary or involuntary or be effected by operation of law or pursuant to
any judgment, decree or order of any court or any order, rule or regulation of
an administrative or governmental body):

     (a) default in the payment of any interest upon any Securities of that
series or any Other Debentures when it becomes due and payable, and continuance
of such default for a period of 30 days; provided, however, that a valid
extension of an interest payment period by the Company in accordance with the
terms of any particular series of Securities established as contemplated in this
Indenture, shall not constitute a default in the payment of interest for this
purpose; or

     (b) default in the payment of all or any part of the principal on any
Securities of that series or any Other Debentures as and when the same shall
become due and payable either at maturity, upon prepayment or redemption, by
declaration of acceleration of maturity or otherwise; or

     (c) default in the performance, or breach, of any covenant or warranty of
the Company in this Indenture (other than a covenant or warranty a default in
whose performance or whose breach is elsewhere in this Section specifically
dealt with and other than those set forth exclusively in the terms of any
particular series (and specifically limited to) of Securities established as
contemplated in this Indenture), and continuance of such default or breach for a
period of 90 days after there has been given, by registered or certified mail,
to the Company by the Trustee or to the Company and the Trustee by the holders
of at least 25% in aggregate principal amount of the outstanding Securities a
written notice specifying such default or breach and requiring it to be remedied
and stating that such notice is a Notice of Default hereunder; or

     (d) a court having jurisdiction in the premises shall enter a decree or
order for relief in respect of the Company in an involuntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or appointing a receiver, liquidator, assignee, custodian, trustee,
sequestrator (or similar official) of the Company or for any substantial part of
its property, or ordering the winding-up or liquidation of its affairs and such
decree or order shall remain unstayed and in effect for a period of 90
consecutive days; or

     (e) the Company shall commence a voluntary case under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, shall
consent to the entry of an order for relief in an involuntary case under any
such law, or shall consent to the appointment of or taking possession by a
receiver, liquidator, assignee, trustee, custodian, sequestrator (or other
similar official) of the Company or of any substantial part of its property, or
shall make any general assignment for the benefit of creditors, or shall fail
generally to pay its debts as they become due.

     If an Event of Default with respect to any series of Securities at the time
outstanding occurs and is continuing, then in every such case the Trustee or the
holders of not less than 25% in aggregate principal amount of the Securities of
that series then outstanding may declare the principal amount of all Securities
of that series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by the holders of the outstanding
Securities of that series), and upon any such declaration the same shall become
immediately due and payable. Notwithstanding the foregoing, if an Event of
Default specified in clause (d) or (e) of Section 5.1 occurs, the Securities of
such series then outstanding shall be due and payable immediately without
further action or notice.

     The foregoing provisions, however, are subject to the condition that if, at
any time after the principal of the Securities of any series (or of all the
Securities, as the case may be) 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, (i) the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay (A) all matured installments of
interest upon all the Securities of such series (or of all the Securities, as
the case may be) and the principal of any and all Securities of such series (or
of all the Securities, as the case may be) which shall

                                      17
<PAGE>

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 specified in the Securities of that series (or at the
respective rates of interest of all the Securities, as the case may be) to the
date of such payment or deposit) and (B) such amount as shall be sufficient to
cover compensation due to the Trustee and each predecessor Trustee, their
respective agents, attorneys and counsel, pursuant to Section 6.6, and (ii) any
and all Events of Default under this Indenture, other than the non-payment of
the principal of the Securities which shall have become due solely by such
declaration of acceleration, shall have been cured, waived or otherwise remedied
as provided herein, then, in every such case, the holders of a majority in
aggregate principal amount of the Securities of such series (or of all the
Securities, as the case may be) then outstanding, by written notice to the
Company and to the Trustee, may rescind and annul such declaration and its
consequences, but no such waiver or rescission and annulment shall extend to or
shall affect any subsequent default or shall impair any right consequent
thereon; provided, however, that if the Securities of such series (or all of the
Securities, as the case may be) are held by the Property Trustee, such waiver or
rescission and annulment to such waiver shall not be effective until the holders
of a majority in aggregate liquidation amount of Trust Securities of such
Sterling Capital Trust shall have consented to such waiver or rescission and
annulment to such waiver.

     In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because
of such rescission or annulment or for any other reason or shall have been
determined adversely to the Trustee, then and in every such case the Company,
the Trustee and the holders of the Securities shall be restored respectively to
their several positions and rights hereunder, and all rights, remedies and
powers of the Company, the Trustee and the holders of the Securities shall
continue as though no such proceeding had been taken.

SECTION 5.2   Payment of Securities on Default; Suit Therefor.

     The Company covenants that (a) in case default shall be made in the payment
of any installment of interest upon any of the Securities of a series as and
when the same shall become due and payable, and such default shall have
continued for a period of 30 days, or (b) in case default shall be made in the
payment of the principal of any of the Securities of a series as and when the
same shall have become due and payable, whether at maturity of the Securities of
that series or upon prepayment or redemption or by declaration or otherwise,
then, upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the holders of the Securities of that series, the whole amount that
then shall have become due and payable on all such Securities of that series for
principal or interest with interest upon the overdue principal and (to the
extent that payment of such interest is enforceable under applicable law and, if
the Securities are held by Sterling Capital Trust or a trustee of such trust,
without duplication of any other amounts paid by the Sterling Capital Trust or a
trustee in respect thereof) upon the overdue installments of interest at the
rate borne by the Securities of that series; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including a reasonable compensation to the Trustee, its agents,
attorneys and counsel, and any other amount due to the Trustee pursuant to
Section 6.6.

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

     In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other obligor on the Securities under Title
11, United States Code, or any other applicable law, or in case a receiver or
trustee shall have been appointed for the property of the Company or such other
obligor, or in the case of any other similar judicial proceedings relative to
the Company or other obligor upon the Securities, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Securities of any series 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 5.2, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal and interest owing and unpaid in respect of the Securities
of such series and, in case of any judicial proceedings, to file such proofs of
claim and other papers or documents as may be necessary or

                                      18
<PAGE>

advisable in order to have the claims of the Trustee (including any claim for
amounts due to the Trustee pursuant to 6.6) and of the Securityholders allowed
in such judicial proceedings relative to the Company or any other obligor on the
Securities of any series, or to the creditors or property of the Company or such
other obligor, unless prohibited by applicable law and regulations, to vote on
behalf of the holders of the Securities of any series 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 to collect and receive any moneys or
other property payable or deliverable on any such claims, and to distribute the
same after the deduction of its charges and expenses; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
Securityholders to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, 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 amounts due to the
Trustee pursuant to Section 6.6.

     Nothing herein contained shall be construed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan of reorganization, arrangement, adjustment or composition affecting the
Securities of any 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.

     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 on any trial or other
proceeding relative thereto, and any such suit or proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall be for the ratable benefit of the holders of the
Securities.

     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, and it shall not be necessary to make any holders of the
Securities parties to any such proceedings.

SECTION 5.3   Application of Moneys Collected by Trustee.

     Any moneys collected by the Trustee shall be applied in the following
order, at the date or dates fixed by the Trustee for the distribution of such
moneys, upon presentation of the several Securities in respect of which moneys
have been collected, and stamping thereon the payment, if only partially paid,
and upon surrender thereof if fully paid:

     First:  To the payment of costs and expenses of collection applicable to
the Securities of such series and all other amounts due to the Trustee under
Section 6.6;

     Second:  To the payment of all Senior Indebtedness of the Company if and to
the extent required by Article XV;

     Third:  In case the principal of the outstanding Securities in respect of
which moneys have been collected shall not have become due and be unpaid, to the
payment of the amounts then due and unpaid upon Securities of such series for
principal of and interest on the Securities of such series, in respect of which
or for the benefit of which money has been collected, ratably, without
preference of priority of any kind, according to the amounts due on such
Securities for principal and interest, respectively; and

     Fourth:  To the Company.

SECTION 5.4  Proceedings by Securityholders.

     No holder of any Security of any series shall have any right by virtue of
or by availing of any provision of this Indenture to institute any suit, action
or proceeding in equity or at law upon or under or with respect to this
Indenture or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless such holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof with

                                      19
<PAGE>

respect to the Securities of such series specifying such Event of Default, as
hereinbefore provided, and unless also the holders of not less than 25% in
aggregate principal amount of the Securities of that series then outstanding
shall have made written request upon the Trustee to institute such action, suit
or proceeding 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, suit or proceeding, it being understood and
intended, and being expressly covenanted by the taker and holder of every
Security with every other taker and holder and the Trustee, that no one or more
holders of Securities of any series shall have any right in any manner whatever
by virtue of or by availing of any provision of this Indenture to affect,
disturb or prejudice the rights of any other 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 the
applicable series.

     Notwithstanding any other provisions in this Indenture, however, the right
of any holder of any Security to receive payment of the principal of and
interest on such Security, on or after the same shall have become due and
payable, or to institute suit for the enforcement of any such payment, shall not
be impaired or affected without the consent of such holder and by accepting a
Security hereunder it is expressly understood, intended and covenanted by the
taker and holder of every Security of such series with every other such taker
and holder and the Trustee, that no one or more holders of Securities of such
series shall have any right in any manner whatsoever by virtue or by availing of
any provision of this Indenture to affect, disturb or prejudice the rights of
the holders of any other such 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 such 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
either at law or in equity.

     The Company and the Trustee acknowledge that pursuant to each Declaration,
the holders of Preferred Securities are entitled, in the circumstances and
subject to the limitations set forth therein, to commence a Direct Action with
respect to any Event of Default under this Indenture and the Securities.

SECTION 5.5   Proceedings by Trustee.

     In case an Event of Default occurs with respect to Securities 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 by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in 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 5.6   Remedies Cumulative and Continuing.

     All powers and remedies given by this Article V to the Trustee or to the
Securityholders shall, to the extent permitted by law, be deemed cumulative and
not exclusive of any other powers and remedies available to the Trustee or the
holders of the Securities, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this
Indenture or otherwise established with respect to the Securities of any series,
and no delay or omission of the Trustee or of any holder of any of the
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 default or an acquiescence
therein; and, subject to the provisions of Section 5.4, every power and remedy
given by this Article V or by law to the Trustee or to the Securityholders may
be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Securityholders.

SECTION 5.7   Direction of Proceedings and Waiver of Defaults by Majority of
              Securityholders.

     The holders of a majority in aggregate principal amount of the Securities
of any or all series affected (voting as one class) 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;

                                      20
<PAGE>

provided, however, 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
shall determine that the action so directed would be unjustly prejudicial to the
holders not taking part in such direction or if the Trustee being advised by
counsel determines that the action or proceeding so directed may not lawfully be
taken or if the Trustee in good faith by its board of directors or trustees,
executive committee, or a trust committee of directors or trustees and/or
Responsible Officers shall determine that the action or proceedings so directed
would involve the Trustee in personal liability. Prior to any declaration
accelerating the maturity of any series of the Securities, the holders of a
majority in aggregate principal amount of the Securities of that series at the
time outstanding may on behalf of the holders of all of the Securities of such
series waive any past default or Event of Default and its consequences except a
default (a) in the payment of principal of or interest on any of the Securities
or (b) in respect of covenants or provisions hereof which cannot be modified or
amended without the consent of the holder of each Security affected; provided,
however, that if the Securities are held by a Sterling Capital Trust or a
Property Trustee of such Trust, such waiver or modification to such waiver shall
not be effective until the holders of a majority in aggregate liquidation amount
of Trust Securities of the applicable Sterling Capital Trust shall have
consented to such waiver or modification to such waiver; provided further, that
if the consent of the holder of each outstanding Security is required, such
waiver shall not be effective until each holder of the Trust Securities of the
applicable Sterling Capital Trust shall have consented to such waiver. Upon any
such waiver, the default covered thereby shall be deemed to be cured for all
purposes of this Indenture and the Company, the Trustee and the holders of the
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 impair any right consequent thereon. Whenever any default or
Event of Default hereunder shall have been waived as permitted by this Section
5.7, said default or Event of Default shall for all purposes of the Securities
of that series (or of all the Securities, as the case may be) and this Indenture
be deemed to have been cured and to be not continuing.
SECTION 5.8   Notice of Defaults.

     (a) The Trustee shall, within 90 days after the occurrence of a default
known to a Responsible Officer of the Trustee with respect to the Securities of
any series, mail to all Securityholders of that series, as the names and
addresses of such holders appear upon the Security Register, notice of all
defaults with respect to that series actually known to a Responsible Officer of
the Trustee, unless such defaults shall have been cured before the giving of
such notice (the term defaults for the purpose of this Section 5.8 being hereby
defined to be the events specified in clauses (a), (b), (c), (d) and (e) of
Section 5.1, not including periods of grace, if any, provided for therein, and
irrespective of the giving of written notice specified in clause (c) of Section
5.1); and provided that, except in the case of default in the payment of the
principal of or interest on any of the Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as a Responsible
Officer of the Trustee in good faith determines that the withholding of such
notice is in the interests of the Securityholders of such series; and provided
further, that in the case of any default of the character specified in Section
5.1(c), no such notice to Securityholders of such series shall be given until at
least 60 days after the occurrence thereof, but shall be given within 90 days
after such occurrence.

     (b) Within five Business Days after the occurrence of any Event of Default
actually known to a Responsible Officer of the Trustee with respect to any
series, the Trustee shall transmit notice of such Event of Default to all
Securityholders of such series, unless such Event of Default shall have been
cured or waived.

SECTION 5.9   Undertaking to Pay Costs.

     All parties to this Indenture agree, and each holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section 5.9 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder, or group of
Securityholders of any series, holding in the aggregate more than 10% in
aggregate principal amount of the Securities of that series outstanding, or to
any suit instituted by any Securityholder for the enforcement of the payment of
the principal of or interest on any Security against the Company on or after the
same shall have become due and payable.

SECTION 5.10 Requirement to Post Bond.

     Notwithstanding anything contained herein to the contrary, the Trustee
shall not be bound, obligated or required to take any action at the request or
direction of any Securityholder pursuant to this Indenture if such
Securityholder shall not have made available to the Trustee, security or
indemnity reasonably acceptable to the Trustee against the costs, expenses and
liabilities (including fees and expenses of its agents and counsel) which might
be incurred by it in compliance with the written request or direction.

                                      21

                                  ARTICLE VI

                             CONCERNING THE TRUSTEE

SECTION 6.1   Duties and Responsibilities of Trustee.

     With respect to the holders of any series of Securities issued hereunder,
the Trustee, prior to the occurrence of an Event of Default with respect to
Securities of that series of which a Responsible Officer of the Trustee has
actual knowledge and after the curing or waiving of all Events of Default which
may have occurred with respect to Securities of that series, 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 Securities of a series
has occurred (which has not been cured or waived), the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of his or her own affairs.

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

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

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

        (2) in the absence of bad faith on the part of the Trustee, the Trustee
     may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture; but, in the case of any such certificates or opinions 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, 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
Securityholders pursuant to Section 5.7, 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, if there is reasonable ground for believing that the
repayment of such funds or liability is not reasonably assured to it under the
terms of this Indenture or adequate indemnity against such risk is not
reasonably assured to it.

SECTION 6.2  Reliance on Documents, Opinions, etc.

     Except as otherwise provided in :

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

                                      22
<PAGE>

     (b) any request, direction, order or demand of the Company mentioned herein
may be sufficiently evidenced by an Officers' Certificate (unless other evidence
in respect thereof be herein specifically prescribed); and any Board Resolution
may be evidenced to the Trustee by a copy thereof certified by the Secretary or
an Assistant Secretary of the Company;

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

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

     (e) 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 or
rights or powers conferred upon it by this Indenture; nothing contained herein
shall, however, relieve the Trustee of the obligation, upon the occurrence of an
Event of Default with respect to a series of Securities of which a Responsible
Officer of the Trustee has actual knowledge (that has not been cured or waived),
to exercise with respect to Securities of that series such of the rights and
powers vested in it by this Indenture, and to 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;

     (f) the Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, debenture,
coupon or other paper or document, unless requested in writing to do so by the
holders of a majority in aggregate principal amount of the outstanding
Securities of the series affected thereby; provided, however, that if the
payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such expense or liability as a condition to so
proceeding;

     (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents (including
any Authenticating Agent) or attorneys, and the Trustee shall not be responsible
for any misconduct or negligence on the part of any such agent or attorney
appointed by it with due care; and

     (h) the Trustee shall not be charged with knowledge of any Default or Event
of Default with respect to the Securities of any series unless (1) such default
is a default under Section 5.1(a) and Section 5.1(b) of the Indenture, (2) a
Responsible Officer shall have actual knowledge of such Default or Event of
Default or (3) written notice of such Default or Event of Default shall have
been given to the Trustee by the Company or any other obligor on the Securities
of such series or by any holder of the Securities of that series.

SECTION 6.3  No Responsibility for Recitals, etc.

     The recitals contained herein and in the Securities (except in the
certificate of authentication of the Trustee or the Authenticating Agent) shall
be taken as the statements of the Company, and the Trustee and the
Authenticating Agent assume no responsibility for the correctness of the same.
The Trustee and the Authenticating Agent make no representations as to the
validity or sufficiency of this Indenture or of the Securities.  The Trustee and
the Authenticating Agent shall not be accountable for the use or application by
the Company of any Securities or the proceeds of any Securities authenticated
and delivered by the Trustee or the Authenticating Agent in conformity with the
provisions of this Indenture.

                                      23
<PAGE>

SECTION 6.4   Trustee, Authenticating Agent, Paying Agents, Transfer Agents or
Registrar May Own Securities.

     The Trustee or any Authenticating Agent or any paying agent or any transfer
agent or any Security registrar, 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 Trustee, Authenticating Agent, paying agent, transfer agent or
Security registrar.

SECTION 6.5   Moneys to be Held in Trust.

     Subject to the provisions of Section 11.4, all moneys received by the
Trustee or any paying agent shall, until used or applied as herein provided, be
held in trust for the purpose for which they were received, but need not be
segregated from other funds except to the extent required by law. The Trustee
and any paying agent shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed in writing with the Company.
So long as no Event of Default shall have occurred and be continuing, all
interest allowed on any such moneys shall be paid from time to time upon the
written order of the Company, signed by the Chairman of the Board of Directors,
the President or a Vice President or the Treasurer or an Assistant Treasurer of
the Company.

SECTION 6.6   Compensation and Expenses of Trustee.

     The Company, as issuer of Securities under this Indenture, covenants and
agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as shall be agreed to in writing between the
Company 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 Company
will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith.  The Company also covenants to indemnify
each of the Trustee or any predecessor Trustee (and its officers, agents,
directors and employees) for, and to hold it harmless against, any and all loss,
damage, claim, liability or expense including taxes (other than taxes based on
the income of the Trustee) incurred without negligence or bad faith on the part
of the Trustee and arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending
itself against any claim of liability in the premises.  The obligations of the
Company under this Section 6.6 to compensate and indemnify the Trustee and to
pay or reimburse the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder.  Such additional indebtedness
shall be secured by a lien prior 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 benefit of the holders of particular Securities.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(d) or Section 5.1(e), 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.

     The provisions of this Section shall survive the resignation or removal of
the Trustee and the defeasance or other termination of this Indenture.

SECTION 6.7  Officers' Certificate as Evidence.

     Except as otherwise provided in Section 6.1 and Section 6.2, whenever in
the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
omitting any action hereunder, such matter (unless other evidence in respect
thereof is 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 Officers' 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 or omitted by
it under the provisions of this Indenture upon the faith thereof.

                                      24

SECTION 6.8  Conflicting Interest of Trustee.

     If the Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the
Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.

SECTION 6.9   Eligibility of Trustee.

     The Trustee hereunder shall at all times be a corporation organized and
doing business under the laws of the United States of America or any state or
territory thereof or of the District of Columbia, or a corporation or other
Person permitted to act as trustee by the Commission authorized under such laws
to exercise corporate trust powers, having a combined capital and surplus of at
least 50 million U.S. dollars ($50,000,000) and subject to supervision or
examination by Federal, state, territorial, or District of Columbia authority.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 6.9 the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.

     The Company may not, nor may any Person directly or indirectly controlling,
controlled by, or under common control with the Company, serve as Trustee.

     In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 6.9, the Trustee shall resign immediately in
the manner and with the effect specified in Section 6.10.

SECTION 6.10   Resignation or Removal of Trustee.

     (a) The Trustee, or any trustee or trustees hereafter appointed, may at any
time resign with respect to one or more or all series of Securities by giving
written notice of such resignation to the Company and by mailing notice thereof
to the holders of the applicable series of Securities at their addresses as they
shall appear on the Security Register. Upon receiving such notice of
resignation, the Company shall promptly appoint a successor trustee or trustees
by written instrument, in duplicate, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no
successor trustee shall have been so appointed with respect to any series of
Securities and have accepted appointment within 60 days after the mailing of
such notice of resignation to the affected Securityholders, 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 of the applicable series for at least six months may,
subject to the provisions of Section 5.9, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

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

        (1) the Trustee shall fail to comply with the provisions of Section 6.8
     after written request therefor by the Company or by any Securityholder who
     has been a bona fide holder of a Security or Securities for at least six
     months, or

        (2) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 6.9 and shall fail to resign after written request
     therefor by the Company or by any such Securityholder, or

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

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the

                                      25
<PAGE>

successor trustee, or, subject to the provisions of Section 5.9, any
Securityholder who has been a bona fide holder of a Security or Securities of
the applicable series for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor trustee.

     (c) The holders of a majority in aggregate principal amount of the
Securities of any series at the time outstanding may at any time remove the
Trustee with respect to such series and nominate a successor trustee with
respect to the applicable series of Securities or all series, as the case may
be, which shall be deemed appointed as successor trustee with respect to the
applicable series unless within 10 days after such nomination the Company
objects thereto, or if no successor trustee shall have been so appointed and
shall have accepted appointment within 30 days after such removal, in which case
the Trustee so removed or any Securityholder of the applicable series, upon the
terms and conditions and otherwise as in subsection(a) of this Section 6.10
provided, may petition any court of competent jurisdiction for an appointment of
a successor trustee with respect to such series.

     (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 6.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 6.11.

     (e) The Company shall pay the Trustee all amounts owed to such Trustee
pursuant to this Indenture upon the resignation or removal of the Trustee.

SECTION 6.11   Acceptance by Successor Trustee.

     Any successor trustee appointed as provided in Section 6.10 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation
or removal of the retiring trustee with respect to all or any applicable series
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, duties and
obligations with respect to such series of its predecessor hereunder, with like
effect as if originally named as trustee herein; but, nevertheless, on the
written request of the Company or of the successor trustee, the trustee ceasing
to act shall, upon payment of any amounts then due it pursuant to the provisions
of Section 6.6, execute and deliver an instrument transferring to such successor
trustee all the rights and powers of the trustee so ceasing to act and shall
duly assign, transfer and deliver to such successor trustee all property and
money held by such retiring trustee thereunder.  Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee
all such rights and powers.  Any trustee ceasing to act shall, nevertheless,
retain a lien upon all property or funds held or collected by such trustee to
secure any amounts then due it pursuant to the provisions of Section 6.6.

     If a successor trustee is appointed with respect to the Securities of one
or more (but not all) series, the Company, the retiring trustee and each
successor trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring trustee with respect to the
Securities of any series as to which the predecessor trustee is not retiring
shall continue to be vested in the predecessor trustee, and 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 trustee hereunder by more than one
trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such trustees co-trustees of the same trust and that
each such trustee shall be trustee of a trust or trusts hereunder separate and
apart from any trust or trusts hereunder administered by any other such trustee.

     No successor trustee shall accept appointment as provided in this Section
6.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 6.8 and eligible under the provisions
of Section 6.9.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 6.11, the Company shall mail notice of the succession of such trustee
hereunder to the holders of Securities of any applicable series at their
addresses as they shall appear on the Security Register.  If the Company fails
to mail such notice within 10 days

                                      26
<PAGE>

after the acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be mailed at the expense of the Company. No
Trustee shall have any liability for any actions taken or omitted to be taken by
any successor trustee.

SECTION 6.12   Succession by Merger, etc.

     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 all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder without
the execution or filing of any paper or any further act on the part of any of
the parties hereto.

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

SECTION 6.13   Limitation on Rights of Trustee as a Creditor.

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship described in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.

SECTION 6.14   Authenticating Agents.

     There may be one or more Authenticating Agents appointed by the Trustee
upon the request of the Company with power to act on its behalf and subject to
its direction in the authentication and delivery of Securities of any series
issued upon exchange or transfer thereof as fully to all intents and purposes as
though any such Authenticating Agent had been expressly authorized to
authenticate and deliver Securities of such series; provided, that the Trustee
shall have no liability to the Company for any acts or omissions of the
Authenticating Agent with respect to the authentication and delivery of
Securities of any series.  Any such Authenticating Agent shall at all times be a
corporation organized and doing business under the laws of the United States or
of any state or territory thereof or of the District of Columbia authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of at least $50,000,000 and being subject to supervision or examination
by Federal, state, territorial or District of Columbia authority.  If such
corporation publishes reports of condition at least annually pursuant to law or
the requirements of such authority, then for the purposes of this Section 6.14
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.  If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect herein specified in this Section.

     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, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section 6.14 without the execution or filing of any paper or any further act on
the part of the parties hereto or such Authenticating Agent.

     Any Authenticating Agent may at any time resign with respect to one or more
or all series of Securities by giving written notice of resignation to the
Trustee and to the Company.  The Trustee may at any time terminate the

                                      27
<PAGE>

agency of any Authenticating Agent with respect to one or more or all series of
Securities by giving written notice of termination to such Authenticating Agent
and to the Company. 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 under this Section 6.14, the Trustee may, and upon the request of the
Company shall, promptly appoint a successor Authenticating Agent with respect to
the applicable series eligible under this Section 6.14, shall give written
notice of such appointment to the Company and shall mail notice of such
appointment to all holders of the applicable series of Securities as the names
and addresses of such holders appear on the Security Register. Any successor
Authenticating Agent with respect to all or any series upon acceptance of its
appointment hereunder shall become vested with all rights, powers, duties and
responsibilities with respect to such series of its predecessor hereunder, with
like effect as if originally named as Authenticating Agent herein.

     The Company, as borrower, agrees to pay to any Authenticating Agent from
time to time reasonable compensation for its services.  Any Authenticating Agent
shall have no responsibility or liability for any action taken by it as such in
accordance with the directions of the Trustee.

                                  ARTICLE VII

                         CONCERNING THE SECURITYHOLDERS

SECTION 7.1   Action by Securityholders.

     Whenever in this Indenture it is provided that the holders of a specified
percentage in aggregate principal amount of the Securities of any or all series
may take any action (including the making of any demand or request, the giving
of any notice, consent or waiver or the taking of any other action), the fact
that at the time of taking any such action the holders of such specified
percentage have joined therein may be evidenced (a) by any instrument or any
number of instruments of similar tenor executed by such Securityholders in
person or by agent or proxy appointed in writing, or (b) by the record of such
holders of Securities voting in favor thereof at any meeting of such
Securityholders duly called and held in accordance with the provisions of
Article VIII, or (c) by a combination of such instrument or instruments and any
such record of such a meeting of such Securityholders.

     If the Company shall solicit from the Securityholders of any series any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of outstanding Securities of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the outstanding Securities of that series
shall be computed as of the record date; provided, however, that no such
authorization, agreement or consent by such Securityholders on the record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than six months after the record date.

SECTION 7.2   Proof of Execution by Securityholders.

     Subject to the provisions of Section 6.1, Section 6.2, and Section 8.5,
proof of the execution of any instrument by a Securityholder or his agent or
proxy shall be sufficient if made in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee.  The ownership of Securities shall be proved by the
Security Register or by a certificate of the Security registrar.  The Trustee
may require such additional proof of any matter referred to in this Section as
it shall deem necessary.

     The record of any Securityholders' meeting shall be proved in the manner
provided in Section 8.6.

                                      28
<PAGE>

SECTION 7.3   Who Are Deemed Absolute Owners.

     Prior to due presentment for registration of transfer of any Security, the
Company, the Trustee, any Authenticating Agent, any paying agent, any transfer
agent and any Security registrar may deem the person in whose name such Security
shall be registered upon the Security Register to be, and may treat him as, the
absolute owner of such Security (whether or not such Security shall be overdue)
for the purpose of receiving payment of or on account of the principal of and
interest on such Security and for all other purposes; and neither the Company
nor the Trustee nor any Authenticating Agent nor any paying agent nor any
transfer agent nor any Security registrar shall be affected by any notice to the
contrary.  All such payments so made to any holder for the time being or upon
his order shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for moneys payable upon any
such Security.

SECTION 7.4   Securities Owned by Company Deemed Not Outstanding.

     In determining whether the holders of the requisite aggregate principal
amount of Securities have concurred in any direction, consent or waiver under
this Indenture, Securities which are owned by the Company or any other obligor
on the Securities or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
other obligor on the Securities shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, consent or waiver, only Securities which a Responsible Officer
of the Trustee actually knows are so owned shall be so disregarded.  Securities
so owned which have been pledged in good faith may be regarded as outstanding
for the purposes of this Section 7.4 if the pledgee shall establish to the
satisfaction of the Trustee the pledgee's right to vote such Securities and that
the pledgee is not the Company or any such other obligor or Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor. In the case of a dispute as
to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee.

SECTION 7.5   Revocation of Consents; Future Holders Bound.

     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 Security specified in this
Indenture in connection with such action, any holder of a Security (or any
Security issued in whole or in part in exchange or substitution therefor),
subject to Section 7.1, the serial number of which is shown by the evidence to
be included in the group of Securities the holders of which have consented to
such action may, by filing written notice with the Trustee at its principal
office and upon proof of holding as provided in Section 7.2, revoke such action
so far as concerns such Security (or so far as concerns the principal amount
represented by any exchanged or substituted Security).  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 Security issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon such Security or any
Security issued in exchange or substitution therefor.

                                 ARTICLE VIII

     A meeting of Securityholders of any or all series may be called at any time
and from time to time pursuant to the provisions of this Article VIII for any of
the following purposes:

     (a) to give any notice to the Company or to the Trustee, or to give any
directions to the Trustee, or to consent to the waiving of any default hereunder
and its consequences, or to take any other action authorized to be taken by
Securityholders pursuant to any of the provisions of Article V;

     (b) to remove the Trustee and nominate a successor trustee pursuant to the
provisions of Article VI;

                                      29
<PAGE>

     (c) to consent to the execution of an indenture or indentures supplemental
hereto pursuant to the provisions of Section 9.2; or

     (d) to take any other action authorized to be taken by or on behalf of the

other provision of this Indenture or under applicable law.

SECTION 8.2   Call of Meetings by Trustee.

     The Trustee may at any time call a meeting of Securityholders of any or all
series to take any action specified in Section 8.1, to be held at such time and
at such place in the Borough of Manhattan, The City of New York, as the Trustee
shall determine.  Notice of every meeting of the Securityholders of any or all
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be mailed to
holders of Securities of each series affected at their addresses as they shall
appear on the Securities Register.  Such notice shall be mailed not less than 20
nor more than 180 days prior to the date fixed for the meeting.

SECTION 8.3   Call of Meetings by Company or Securityholders.

     In case at any time the Company, pursuant to a resolution of the Board of
Directors, or the holders of at least 10% in aggregate principal amount of the
Securities of any or all series, as the case may be, then outstanding, shall
have requested the Trustee to call a meeting of Securityholders of any or all
series, as the case may be, by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not
have mailed the notice of such meeting within 20 days after receipt of such
request, then the Company or such Securityholders may determine the time and the
place in said Borough of Manhattan for such meeting and may call such meeting to
take any action authorized in Section 8.1, by mailing notice thereof as provided
in Section 8.2.

SECTION 8.4   Qualifications for Voting.

     To be entitled to vote at any meeting of Securityholders a Person shall (a)
be a holder of one or more Securities with respect to which the meeting is being
held or (b) a Person appointed by an instrument in writing as proxy by a holder
of one or more such Securities.  The only Persons who shall be entitled to be
present or to speak at any meeting of Securityholders shall be the Persons
entitled to vote at such meeting and their counsel and any representatives of
the Trustee and its counsel and any representatives of the Company and its
counsel.

SECTION 8.5   Regulations.

     Notwithstanding any other provisions of this Indenture, the Trustee may

appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

     The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Securityholders as provided in Section 8.3, in which case the
Company or the Securityholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman.  A permanent chairman and a permanent

     Subject to the provisions of Section 8.4, at any meeting each holder of
Securities with respect to which such meeting is being held or proxy therefor
shall be entitled to one vote for each $25 principal amount of Securities held
or represented by him; provided, however, that no vote shall be cast or counted
at any meeting in respect of any Security challenged as not outstanding and
ruled by the chairman of the meeting to be not outstanding.  The chairman of the
meeting shall have no right to vote other than by virtue of Securities held by
him or instruments in writing as aforesaid duly designating him as the person to
vote on behalf of other Securityholders.  Any meeting of

                                      30
<PAGE>

Securityholders duly called pursuant to the provisions of Section 8.2 or Section
8.3 may be adjourned from time to time by a majority of those present in person
and by proxy, and the meeting may be held as so adjourned without further
notice.

SECTION 8.6   Voting.

any resolution and who shall make and file with the secretary of the meeting
their verified written reports in triplicate of all votes cast at the meeting.
A record in duplicate of the proceedings of each meeting of Securityholders
shall be prepared by the secretary of the meeting and there shall be attached to
said record the original reports of the inspectors of votes on any vote by
ballot taken thereat and affidavits by one or more persons having knowledge of
the facts setting forth a copy of the notice of the meeting and showing that
said notice was mailed as provided in Section 8.2.  The record shall show the
serial numbers of the Securities voting in favor of or against any resolution.
The record shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one of the duplicates shall be
delivered to the Company and the other to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the meeting.

                            SUPPLEMENTAL INDENTURES

SECTION 9.1  Supplemental Indentures without Consent of Securityholders.

     The Company and the Trustee may from time to time and at any time enter
into an indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act as then in effect), without the consent of
the Securityholders, for one or more of the following purposes:

     (a) to evidence the succession of another corporation to the Company, or
successive successions, and the assumption by the successor corporation of the
covenants, agreements and obligations of the Company pursuant to Article X
hereof;

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

     (e) to evidence and provide for the acceptance of appointment hereunder by

of the holders of any series of Securities.

     The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not be
obligated to, but may in its discretion, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

     With the consent (evidenced as provided in Section 7.1) of the holders of
not less than a majority in aggregate principal amount of the Securities at the
time outstanding of all series affected by such supplemental indenture (voting
as a class), and in the case of Securities issued to a Sterling Capital Trust,
the holders of a majority in aggregate liquidation amount of the related
Preferred Securities, the Company, when authorized by a Board Resolution, and
the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto (which shall conform to the provisions of the
Trust Indenture Act then in effect) for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of this Indenture
or of any supplemental indenture or of modifying in any manner the rights of the
holders of the Securities of each series so affected; provided, however, that no
such supplemental indenture shall, without the consent of the holders of each
Security affected thereby (and each Preferred Security, if applicable), (i)
extend or change the fixed maturity of any Security of any series (except as may
otherwise be provided by the terms of any supplemental indenture establishing
such series in accordance with Section 2.2 hereof), or reduce the rate of
interest thereon or extend the time of payment of interest thereon (except as
may otherwise be provided by the terms of any supplemental indenture
establishing such series in accordance with Section 2.2 hereof), or reduce the
principal amount thereof or any premium thereon, or reduce any amount payable on
redemption thereof or make the principal thereof or any interest or premium
thereon payable in any coin or currency other than that provided in the
Securities, or impair or affect the right of any Securityholder to institute
suit for payment thereof or the right of repayment, if any, at the option of the
holder, without the consent of the holder of each Security so affected, (ii)
reduce the aforesaid percentage of Securities the holders of which are required
to consent to any such supplemental indenture or (iii) otherwise materially
adversely affect the interest of the holders of any series of the Securities or
the Preferred Securities; provided, further, that if the Securities of such
series are held by a Sterling Capital Trust or a trustee of such trust, such
supplemental indenture shall not be effective until the holders of a majority in
liquidation preference of Trust Securities of the applicable Trust shall have
consented to such supplemental indenture; provided further, that if the consent
of the holder of each outstanding Security is required, such supplemental
indenture shall not be effective until each holder of the Trust Securities of
the applicable Sterling Capital Trust shall have consented to such supplemental
indenture.

     A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of Securityholders of such series with respect to such covenant or
provision, shall be deemed not to affect the rights under this Indenture or the
Securityholders of any other series.

     Upon the request of the Company accompanied by a copy of a resolution of
the Board of Directors certified by its Secretary or Assistant Secretary
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Securityholders as
aforesaid, the Trustee shall join with the Company in the execution of such
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 may in its discretion, but shall not be obligated to, enter
into such supplemental indenture. The Trustee may receive an Opinion of Counsel
as conclusive evidence that any supplemental indenture executed pursuant to this
Article is authorized or permitted by, and conforms to, the terms of this
Article and that it is proper for the Trustee under the provisions of this
Article to join in the execution thereof.

     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall transmit by mail, first class postage prepaid, a notice, setting forth in
general terms the substance of such supplemental indenture, to the
Securityholders of all series affected thereby as their names and addresses
appear upon the Security Register. Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

     It shall not be necessary for the consent of the Securityholders under this
Section 9.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

SECTION 9.3  Compliance with Trust Indenture Act; Effect of Supplemental
Indentures.

     Any supplemental indenture executed pursuant to the provisions of this
Article IX shall comply with the Trust Indenture Act, as then in effect. Upon
the execution of any supplemental indenture pursuant to the provisions of this
Article IX, this Indenture shall be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Securities of each series affected thereby shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

SECTION 9.4  Notation on Securities.

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture affecting such series pursuant to the provisions of
this ARTICLE IX may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company or the
Trustee shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee and the Board of Directors, to any
modification of this Indenture contained in any such supplemental indenture
maybe prepared and executed by the Company, authenticated by the Trustee or the
Authenticating Agent and delivered in exchange for the Securities of any series
then outstanding.

SECTION 9.5  Evidence of Compliance of Supplemental Indenture to be Furnished
Trustee.

     The Trustee, subject to the provisions of Section 6.1 and Section 6.2, may
receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant hereto complies with
the requirements of this ARTICLE IX.

               CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

SECTION 10.1   Company May Consolidate, etc., on Certain Terms.

     Nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of the Company with or into any other Person
(whether or not affiliated with the Company, as the case may be), or successive
consolidations or mergers in which the Company or its successor or successors,
as the case may be, shall be a party or parties, or shall prevent any sale,
conveyance, transfer or lease of the property of the Company, or its successor
or successors as the case may be, as an entirety, or substantially as an
entirety, to any other Person (whether or not affiliated with the Company, or
its successor or successors, as the case may be) authorized to acquire and
operate the same; provided, that (a) the Company is the surviving Person, or the
Person formed by or surviving any such consolidation or merger (if other than
the Company) or to which such sale, conveyance, transfer or lease of property is
made is a Person organized and existing under the laws of the United States or
any State thereof or the District of Columbia, and (b) upon any such
consolidation, merger, sale, conveyance, transfer or lease, the due and punctual
payment of the principal of and interest on all of the Securities of all series
in accordance with the terms of each series, according to their tenor and the
due and punctual performance and observance of all the covenants and conditions
of this Indenture with respect to each series or established with respect to
such series to be kept or performed by the Company shall be expressly assumed,
by supplemental indenture (which shall conform to the provisions of the Trust
Indenture Act) satisfactory in form to the Trustee executed and delivered to the
Trustee by the Person formed by such consolidation, or into which the Company
shall have been merged, or by the Person which shall have acquired such
property, as the case may be, and (c) after giving effect to such consolidation,
merger, sale, conveyance, transfer or lease, no Default or Event of Default
shall have occurred and be continuing.

SECTION 10.2   Successor Corporation to be Substituted for Company.

     In case of any such consolidation, merger, conveyance or transfer 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
obligation of due and punctual payment of the principal of and interest on all
of the Securities and the due and punctual performance and observance of all of
the covenants and conditions of this Indenture to be performed or observed by
the Company, such successor Person shall succeed to and be substituted for the
Company, with the same effect as if it had been named herein as the party of the
first part, and the Company thereupon shall be relieved of any further liability
or obligation hereunder or upon the Securities.  Such successor Person thereupon
may cause to be signed, and may issue either in its own name or in the name of
Sterling Capital Trust, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee or the Authenticating Agent; and, upon the order of such successor
Person instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee or the Authenticating
Agent shall authenticate and deliver any Securities which previously shall have
been signed and delivered by the officers of the Company to the Trustee or the
Authenticating Agent for authentication, and any Securities which such successor
Person thereafter shall cause to be signed and delivered to the Trustee or the
Authenticating Agent 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 Indentures had been issued at the date of the
execution hereof.

SECTION 10.3   Opinion of Counsel to be Given Trustee.

     The Trustee, subject to the provisions of Section 6.1 and Section 6.2 may
receive an Opinion of Counsel as conclusive evidence that any consolidation,
merger, sale, conveyance, transfer or lease, and any assumption, permitted or
required by the terms of this Article X complies with the provisions of this
Article X.

SECTION 11.1   Discharge of Indenture.

     When (a) the Company shall deliver to the Trustee for cancellation all
Securities theretofore authenticated (other than any Securities which shall have
been destroyed, lost or stolen and which shall have been replaced as provided in
Section 2.7) and not theretofore cancelled, or (b) all the Securities not
theretofore cancelled or delivered to the Trustee for cancellation shall 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, and the
Company shall deposit with the Trustee, in trust, funds sufficient to pay at

which shall have been destroyed, lost or stolen and which shall have been
replaced as provided in Section 2.7) not theretofore cancelled or delivered to
the Trustee for cancellation, including principal (and premium, if any) and
interest due or to become due to such date of maturity or redemption date, as
the case may be, but excluding, however, the amount of any moneys for the
payment of principal of or interest on the Securities (1) theretofore repaid to
the Company in accordance with the provisions of Section 11.4, or (2) paid to
any State or to the District of Columbia pursuant to its unclaimed property or
similar laws, and if in either case the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company, then this Indenture shall
cease to be of further effect except for the provisions of this Section 11.1 and
Sections 2.3, 2.6, 2.7, 3.1, 3.2, 3.4, 6.6, 6.10 and 11.4 hereof, which shall

Section 11.1 and Sections 6.6, 6.10 and 11.4 shall survive, and the Trustee, on
demand of the Company accompanied by any Officers' Certificate and an Opinion of
Counsel and at the cost and expense of the Company, shall execute proper

expenses thereafter reasonably and properly incurred by the Trustee in
connection with this Indenture or the Securities.

SECTION 11.2  Deposited Moneys and U.S. Government Obligations to be Held in

shall be held in trust and applied by it to the payment, either directly or
through any paying agent (including the Company if acting as its own paying
agent), to the holders of the particular Securities for the payment of which
such moneys or U.S. Government Obligations have been deposited with the Trustee,
of all sums due and to become due thereon for principal and interest.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations

respect thereof other than any such tax, fee or other charge which by law is for
the account of the holders of outstanding Securities.

SECTION 11.3  Paying Agent to Repay Moneys Held.

     Upon the satisfaction and discharge of this Indenture all moneys then held
by any paying agent of the Securities (other than the Trustee) shall, upon
written demand of the Company, 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 11.4  Return of Unclaimed Moneys.

     Any moneys deposited with or paid to the Trustee or any paying agent for
payment of the principal of or interest on Securities and not applied but
remaining unclaimed by the holders of Securities for two years after the date
upon which the principal of or interest on such Securities, as the case may be,
shall have become due and payable, shall be repaid to the Company by the Trustee
or such paying agent on written demand; the holder of any of the Securities
shall thereafter look only to the Company for any payment which such holder may
be entitled to collect and all liability of the Trustee or such paying agent
with respect to such moneys shall thereupon cease.

with the Trustee or the Defeasance Agent (as defined below) as trust funds in
trust, specifically pledged as security for, and dedicated solely to, the
benefit of the holders of the Securities of such series (i) money in an amount,
or (ii) U.S. Government Obligations which through the payment of interest and
principal in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(iii) a combination of (i) and (ii), sufficient, in the opinion (with respect to
(ii) and (iii)) of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee and the Defeasance Agent, if any, to pay and discharge each installment
of principal of and interest on the outstanding Securities of such series on the

series shall have occurred and be continuing on the date of such deposit; and

     (d) the Company shall have delivered to the Trustee and the Defeasance
Agent, if any, an Opinion of Counsel to the effect that holders of the
Securities of such series will not recognize income, gain or loss for United
States Federal income tax purposes as a result of the exercise of the option
under this Section 11.5 and will be subject to United States 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 option had not been exercised, and in the case of the
Securities of such series being Discharged, such opinion shall be based on a
statute so providing or be accompanied by a private letter ruling to that effect
received from the United States Internal Revenue Service or a revenue ruling
pertaining to a comparable form of transaction to that effect published by the
United States Internal Revenue Service.

     "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Securities of such series and to have satisfied all the obligations under this
Indenture relating to the Securities of such series (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), except (A) the rights of holders of Securities of such series to receive,
from the trust fund described in clause (1) above, payment of the principal of
and the interest and premium, if any, on such Securities when such payments are
due; (B) the Company's obligations with respect to the Securities under Sections
2.6, 2.7, 5.2 and 11.4; and (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder.

acknowledging receipt of sufficient money and/or U. S. Government Obligations to
meet the applicable conditions set forth in this Section 11.5.

Preferred Securities may directly institute a proceeding for enforcement of
payment to such holder of the principal of or interest on the applicable series
of Securities having a principal amount equal to the aggregate liquidation
amount of the Trust Preferred Securities of such holder on or after the
respective due date specified in the applicable series of Securities.

                                  ARTICLE XIV

                            PREPAYMENT OF SECURITIES

SECTION 14.1  Applicability of Article.

     The provisions of this Article shall be applicable to the Securities of any
series which, by their terms, may be prepaid before their maturity except as
otherwise as specified as contemplated by Section 2.2 for Securities of such
series.

SECTION 14.2  Notice of Prepayment; Selection of Securities.

     In case the Company shall desire to exercise the right to prepay all, or,
as the case may be, any part of the Securities of any series in accordance with
their terms, it shall fix a date for prepayment and shall mail a notice of such
prepayment at least 30 and not more than 60 days prior to the date fixed for
prepayment to the holders of Securities of such series to be so prepaid as a
whole or in part at their last addresses as the same appear on the Security
Register.  Such mailing shall be by first class mail.  The notice if mailed in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the holder receives such notice.  In any case, failure to
give such notice by mail or any defect in the notice to the holder of any
Security of a series designated for prepayment as a whole or in part shall not
affect the validity of the proceedings for the prepayment of any other Security
of such series.

     Each such notice of prepayment shall identify the Securities to be prepaid
(including the CUSIP number), the date fixed for prepayment, the prepayment
price at which the Securities are to be prepaid (or the method by which such
prepayment price is to be calculated), the place or places of payment that
payment will be made upon presentation and surrender of such Securities, that
interest accrued to the date fixed for prepayment will be paid as specified in
said notice, and that on and after said date interest thereon or on the portions
thereof to be prepaid will cease to accrue.  If less than all the Securities of
such series are to be prepaid, the notice of prepayment shall specify the number
of the Securities of that series to be prepaid.  In case any Security of a
series is to be prepaid in part only, the notice of prepayment shall state the
portion of the principal amount thereof to be redeemed and shall state that on
and after the date fixed for prepayment, upon surrender of such Security, a new
Security or Securities of that series in principal amount equal to the portion
thereof that has not been prepaid will be issued.

                                      39
<PAGE>

     By 10:00 a.m. New York time on the prepayment date specified in the notice
of prepayment given as provided in this Section, the Company will deposit with
the Trustee or with one or more paying agents an amount of money sufficient to
prepay on the prepayment date all the Securities so called for prepayment at the
appropriate prepayment price, together with accrued interest to the date fixed
for prepayment.

     If the Securities of a series are to be redeemed, the Company will give the
Trustee notice not less than 45 days prior to the prepayment date as to the
aggregate principal amount of Securities of that series to be prepaid and, in
the case of partial prepayment, the Trustee shall select, in such manner as in
its sole discretion it shall deem appropriate and fair, the Securities of that
series or portions thereof (in integral multiples of $25, except as otherwise
set forth in the applicable form of Security) to be prepaid.

SECTION 14.3  Payment of Securities Called for Prepayment.

     If notice of prepayment has been given as provided in Section 14.2, the
Securities or portions of Securities of that series with respect to which such
notice has been given shall become due and payable on the date and at the place
or places stated in such notice at the applicable prepayment price, together
with interest accrued to the date fixed for prepayment, and on and after said
date (unless the Company shall default in the payment of such Securities at the
applicable prepayment price, together with interest accrued to said date)
interest on the Securities or portions of Securities so called for prepayment
shall cease to accrue.  On presentation and surrender of such Securities at a
place of payment specified in said notice, the said Securities or the specified
portions thereof shall be paid and prepaid by the Company at the applicable
prepayment price, together with interest accrued thereon to the date fixed for
prepayment.

     Upon presentation of any Security of any series prepaid in part only, the
Company shall execute and the Trustee shall authenticate and make available for
delivery to the holder thereof, at the expense of the Company, a new Security or
Securities of such series of authorized denominations, in principal amount equal
to the portion of the Security so presented that has not been prepaid.

                                  ARTICLE XV

                          SUBORDINATION OF SECURITIES

SECTION 15.1  Agreement to Subordinate.

     The Company covenants and agrees, and each holder of Securities issued
hereunder and under any supplemental indenture or by any Board Resolution
("Additional Provisions") by such Securityholder's acceptance thereof, likewise
covenants and agrees, that all Securities shall be issued subject to the
provisions of this Article XV; and each holder of a Security, whether upon
original issue or upon transfer or assignment thereof, accepts and agrees to be
bound by such provisions.

     The payment by the Company of the principal of and interest on all
Securities issued hereunder and under any Additional Provisions shall, to the
extent and in the manner hereinafter set forth, be subordinated and junior in
right of payment to all Senior Indebtedness, whether outstanding at the date of
this Indenture or thereafter incurred.

     No provision of this Article XV shall prevent the occurrence of any Default
or Event of Default hereunder.

SECTION 15.2  Default on Senior Indebtedness.

     In the event and during the continuation of any default by the Company in
the payment of principal, interest or any other payment due on any Senior
Indebtedness, or in the event that the maturity of any Senior Indebtedness has
been accelerated because of a default, then, in either case, no payment shall be
made by the Company with respect to the principal (including redemption
payments) of or interest on the Securities.

     In the event of the acceleration of the maturity of the Securities, then no
payment shall be made by the Company with respect to the principal (including
redemption payments) of or interest on the Securities until the

                                      40
<PAGE>

holders of all Senior Indebtedness outstanding at the time of such acceleration
shall receive payment in full of such Senior Indebtedness (including any amounts
due upon acceleration).

     In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraphs of this Section 15.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on such Senior Indebtedness, and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of such Senior Indebtedness.

SECTION 15.3  Liquidation; Dissolution; Bankruptcy.

     Upon any payment by the Company or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the
Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all holders of Senior Indebtedness of the
Company shall first be paid in full, or payment thereof provided for in money in
accordance with its terms, before any payment is made by the Company on account
of the principal or interest on the Securities; and upon any such dissolution or
winding-up or liquidation or reorganization, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, which the Securityholders or the Trustee would be
entitled to receive from the Company, except for the provisions of this Article
XV, shall be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the Securityholders or by the Trustee under the Indenture if received by
them or it, directly to the holders of Senior Indebtedness of the Company (pro
rata to such holders on the basis of the respective amounts of Senior
Indebtedness held by such holders, as calculated by the Company) or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, as their respective interests may appear, to the extent
necessary to pay all such Senior Indebtedness in full, in money or money's
worth, after giving effect to any concurrent payment or distribution to or for
the holders of such Senior Indebtedness, before any payment or distribution is
made to the Securityholders or to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character prohibited by the
foregoing, whether in cash, property or securities, shall be received by the
Trustee before all Senior Indebtedness is paid in full, or provision is made for
such payment in money in accordance with its terms, such payment or distribution
shall be held in trust for the benefit of and shall be paid over or delivered to
the holders of such Senior Indebtedness or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Indebtedness may have been issued,
as their respective interests may appear, as calculated by the Company, for
application to the payment of all Senior Indebtedness remaining unpaid to the
extent necessary to pay all such Senior Indebtedness in full in money in
accordance with its terms, after giving effect to any concurrent payment or
distribution to or for the benefit of the holders of such Senior Indebtedness.

     For purposes of this Article XV, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article XV with respect to
the Securities to the payment of Senior Indebtedness that may at the time be
outstanding, provided that (i) such Senior Indebtedness is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment, and
(ii) the rights of the holders of such Senior Indebtedness are not, without the
consent of such holders, altered by such reorganization or readjustment.  The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the sale,
conveyance, transfer or lease of its property as an entirety, or substantially
as an entirety, to another Person upon the terms and conditions provided for in
Article X of this Indenture shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 15.2 if such
other Person shall, as a part of such consolidation, merger, sale, conveyance,
transfer or lease, comply with the conditions stated in

                                      41
<PAGE>

Article X of this Indenture. Nothing in Section 15.2 or in this Section 15.3
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 6.6 of this Indenture.

SECTION 15.4  Subrogation.

     Subject to the payment in full of all Senior Indebtedness, the rights of
the Securityholders shall be subrogated to the rights of the holders of such
Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Company, as the case may be, applicable to such Senior
Indebtedness until the principal of and interest on the Securities shall be paid
in full; and, for the purposes of such subrogation, no payments or distributions
to the holders of such Senior Indebtedness of any cash, property or securities
to which the Securityholders or the Trustee would be entitled except for the
provisions of this Article XV, and no payment over pursuant to the provisions of
this Article XV to or for the benefit of the holders of such Senior Indebtedness
by Securityholders or the Trustee, shall, as between the Company, its creditors
other than holders of Senior Indebtedness of the Company, and the holders of the
Securities, be deemed to be a payment by the Company to or on account of such
Senior Indebtedness.  It is understood that the provisions of this Article XV
are and are intended solely for the purposes of defining the relative rights of
the holders of the Securities, on the one hand, and the holders of such Senior
Indebtedness on the other hand.

     Nothing contained in this Article XV or elsewhere in this Indenture, any
Additional Provisions or in the Securities is intended to or shall impair, as
between the Company, its creditors other than the holders of Senior Indebtedness
of the Company, and the holders of the Securities, the obligation of the
Company, which is absolute and unconditional, to pay to the holders of the
Securities the principal of and interest on the Securities as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the holders of the Securities and
creditors of the Company, as the case may be, other than the holders of Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or the
holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under the Indenture, subject to the rights, if any,
under this Article XV of the holders of such Senior Indebtedness in respect of
cash, property or securities of the Company, as the case may be, received upon
the exercise of any such remedy.

     Upon any payment or distribution of assets of the Company referred to in
this Article XV, the Trustee, subject to the provisions of Article VI of this
Indenture, and the Securityholders shall be entitled to conclusively rely upon
any order or decree made by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidation trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Securityholders, for the purposes of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, as the case may be, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article XV.

SECTION 15.5  Trustee to Effectuate Subordination.

     Each Securityholder by such Securityholder's acceptance thereof authorizes
and directs the Trustee on such Securityholder's behalf to take such action as
may be necessary or appropriate to effectuate the subordination provided in this
Article XV and appoints the Trustee such Securityholder's attorney-in-fact for
any and all such purposes.

SECTION 15.6  Notice by the Company.

     The Company shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Company that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article XV.  Notwithstanding the provisions of this
Article XV or any other provision of this Indenture or any Additional
Provisions, the Trustee shall not be charged with knowledge of the existence of
any facts that would prohibit the making of any payment of monies to or by the
Trustee in respect of the Securities pursuant to the provisions of this Article
XV, unless and until a Responsible Officer of the Trustee shall have received
written notice thereof from the Company or a holder or holders of Senior
Indebtedness or from any trustee therefor; and before the receipt of any such
written notice, the Trustee, subject to the provisions of

                                      42
<PAGE>

Article VI of this Indenture, shall be entitled in all respects to assume that
no such facts exist; provided, however, that if the Trustee shall not have
received the notice provided for in this Section 15.6 at least two Business Days
prior to the date upon which by the terms hereof any money may become payable
for any purpose (including, without limitation, the payment of the principal of
or interest on any Security), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
money and to apply the same to the purposes for which they were received, and
shall not be affected by any notice to the contrary that may be received by it
within two Business Days prior to such date.

     The Trustee, subject to the provisions of Article VI of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Indebtedness of the
Company (or a trustee on behalf of such holder), as the case may be, to
establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee on behalf of any such holder or holders.  In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of such Senior Indebtedness to
participate in any payment or distribution pursuant to this Article XV, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of such Senior Indebtedness held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article XV, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

     Upon any payment or distribution of assets of the Company referred to in
this Article XV, the Trustee and the Securityholders shall be entitled to
conclusively rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other
person making such payment or distribution, delivered to the Trustee or to the
Securityholders, for the purpose of ascertaining the persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article XV.

SECTION 15.7  Rights of the Trustee; Holders of Senior Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article XV in respect of any Senior Indebtedness at any time
held by it, to the same extent as any other holder of Senior Indebtedness, and
nothing in this Indenture shall deprive the Trustee of any of its rights as such
holder.

     With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article XV, and no implied
covenants or obligations with respect to the holders of such Senior Indebtedness
shall be read into this Indenture or any Applicable Provisions against the
Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to the
holders of such Senior Indebtedness and, subject to the provisions of Article VI
of this Indenture, the Trustee shall not be liable to any holder of such Senior
Indebtedness if it shall pay over or deliver to Securityholders, the Company or
any other Person money or assets to which any holder of such Senior Indebtedness
shall be entitled by virtue of this Article XV or otherwise.

     Nothing in this Article XV shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.6.

SECTION 15.8  Subordination May Not Be Impaired.

     No right of any present or future holder of any Senior Indebtedness of the
Company to enforce subordination as herein provided shall at any time in any way
be prejudiced or impaired by any act or failure to act on the part of the
Company, as the case may be, or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company, as the case may be,
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof that any such holder may have or otherwise be charged with.

                                      43
<PAGE>

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness of the Company may, at any time and from time to
time, without the consent of or notice to the Trustee or the Securityholders,
without incurring responsibility to the Securityholders and without impairing or
releasing the subordination provided in this Article XV or the obligations
hereunder of the holders of the Securities to the holders of such Senior
Indebtedness, do any one or more of the following:  (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, such
Senior Indebtedness, or otherwise amend or supplement in any manner such Senior
Indebtedness or any instrument evidencing the same or any agreement under which
such Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of such Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company, as the case may be, and any other
Person.

     Bankers Trust Company hereby accepts the trusts in this Indenture declared
and provided, upon the terms and conditions hereinabove set forth.

     IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed by their respective officers thereunto duly authorized, as of the
day and year first above written.
