...................THIS THIRTEENTH SUPPLEMENTAL INDENTURE is made as of the 28th
day of February, 2003, by and between GEORGIA POWER COMPANY, a Georgia
corporation, 241 Ralph McGill Boulevard, N.E., Atlanta, Georgia 30308-3374 (the
"Company"), and JPMORGAN CHASE BANK, a New York banking corporation, 4 New York
Plaza, New York, New York 10004 (the "Trustee").

                              W I T N E S S E T H:

...................WHEREAS, the Company has heretofore entered into a Senior Note
Indenture, dated as of January 1, 1998 (the "Original Indenture"), with JPMorgan
Chase Bank (formerly known as The Chase Manhattan Bank), as heretofore
supplemented;

...................WHEREAS, the Original Indenture is incorporated herein by this
reference and the Original Indenture, as heretofore supplemented and as further
supplemented by this Thirteenth Supplemental Indenture, is herein called the
"Indenture";

...................WHEREAS, under the Original Indenture, a new series of Senior
Notes may at any time be established by the Board of Directors of the Company in
accordance with the provisions of the Original Indenture and the terms of such
series may be described by a supplemental indenture executed by the Company and
the Trustee;

...................WHEREAS, the Company proposes to create under the Indenture a
new series of Senior Notes;

...................WHEREAS, additional Senior Notes of other series hereafter
established, except as may be limited in the Original Indenture as at the time
supplemented and modified, may be issued from time to time pursuant to the
Indenture as at the time supplemented and modified; and

...................WHEREAS, all conditions necessary to authorize the execution
and delivery of this Thirteenth Supplemental Indenture and to make it a valid
and binding obligation of the Company have been done or performed.

...................NOW, THEREFORE, in consideration of the agreements and
obligations set forth herein and for other good and valuable consideration, the
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as
follows:


                                    ARTICLE 1

                              Series M Senior Notes

..........SECTION 101. Establishment. There is hereby established a new series of
Senior Notes to be issued under the Indenture, to be designated as the Company's
Series M 5.40% Senior Insured Quarterly Notes due March 1, 2033 (the "Series M
Notes").

..........There are to be authenticated and delivered $150,000,000 principal
amount of Series M Notes, and such principal amount of the Series M Notes need
not be issued at the same time and such series may be reopened at any time,
without the consent of the Holders thereof, for issuance of additional Series M
Notes. Any such additional Series M Notes will have the same interest rate,
maturity and other terms, including the benefit of the Policy, as those
initially issued. No Series M Notes shall be authenticated and delivered except
as provided by Sections 203, 303, 304, 907 or 1107 of the Original Indenture.
The Series M Notes shall be issued in definitive fully registered form.

..........The Series M Notes shall be issued in the form of one or more Global
Securities in substantially the form set out in Exhibit A hereto. The Depositary
with respect to the Series M Notes shall be The Depository Trust Company.

..........The form of the Trustee's Certificate of Authentication for the Series
M Notes shall be in substantially the form set forth in Exhibit B hereto.

..........Each Series M Note shall be dated the date of authentication thereof
and shall bear interest from the date of original issuance thereof or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for.

..........SECTION 102. Definitions. The following defined terms used herein
shall, unless the context otherwise requires, have the meanings specified below.
Capitalized terms used herein for which no definition is provided herein shall
have the meanings set forth in the Original Indenture.

.........."Insurer" means XL Capital Assurance Inc., a New York stock insurance
corporation.

         "Interest Payment Dates" means March 1, June 1, September 1 and
December 1 of each year, commencing June 1, 2003.

.........."Original Issue Date" means February 28, 2003.

.........."Policy" means the financial guaranty insurance policy issued by the
Insurer with respect to payments due for principal of and interest on the Series
M Notes as provided in such policy.

.........."Regular Record Date" means, with respect to each Interest Payment
Date, the close of business on the 15th calendar day preceding such Interest
Payment Date (whether or not a Business Day).

.........."Stated Maturity" means March 1, 2033.

..........SECTION 103. Payment of Principal and Interest. The principal of the
Series M Notes shall be due at Stated Maturity (unless earlier redeemed). The
unpaid principal amount of the Series M Notes shall bear interest at the rate of
5.40% per annum until paid or duly provided for. Interest shall be paid
quarterly in arrears on each Interest Payment Date to the Person in whose name
the Series M Notes are registered on the Regular Record Date for such Interest
Payment Date, provided that interest payable at the Stated Maturity of principal
or on a Redemption Date as provided herein will be paid to the Person to whom
principal is payable. Any such interest that is not so punctually paid or duly
provided for will forthwith cease to be payable to the Holders on such Regular
Record Date and may either be paid to the Person or Persons in whose name the
Series M Notes are registered at the close of business on a Special Record Date
for the payment of such defaulted interest to be fixed by the Trustee, notice
whereof shall be given to Holders of the Series M Notes not less than ten (10)
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange,
if any, on which the Series M Notes shall be listed, and upon such notice as may
be required by any such exchange, all as more fully provided in the Original
Indenture.

..........Payments of interest on the Series M Notes will include interest
accrued to but excluding the respective Interest Payment Dates. Interest
payments for the Series M Notes shall be computed and paid on the basis of a
360-day year of twelve 30-day months. In the event that any date on which
interest is payable on the Series M Notes is not a Business Day, then a payment
of the interest payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), with the same force and effect as if made on the date the
payment was originally payable.

..........Payment of the principal and interest due at the Stated Maturity or
earlier redemption of the Series M Notes shall be made upon surrender of the
Series M Notes at the Corporate Trust Office of the Trustee. The principal of
and interest on the Series M Notes shall be paid in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts. Payments of interest (including interest on any
Interest Payment Date) will be made, subject to such surrender where applicable,
at the option of the Company, (i) by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register or (ii)
by wire transfer at such place and to such account at a banking institution in
the United States as may be designated in writing to the Trustee at least
sixteen (16) days prior to the date for payment by the Person entitled thereto.

..........SECTION 104. Denominations. The Series M Notes may be issued in the
denominations of $1,000, or any integral multiple thereof.

..........SECTION 105. Global Security. The Series M Notes will be issued in the
form of one or more Global Securities registered in the name of the Depositary
(which shall be The Depository Trust Company) or its nominee. Except under the
limited circumstances described below, Series M Notes represented by one or more
Global Securities will not be exchangeable for, and will not otherwise be
issuable as, Series M Notes in definitive form. The Global Securities described
above may not be transferred except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or to a successor Depositary or its nominee.

..........Owners of beneficial interests in such a Global Security will not be
considered the Holders thereof for any purpose under the Indenture, and no
Global Security representing a Series M Note shall be exchangeable, except for
another Global Security of like denomination and tenor to be registered in the
name of the Depositary or its nominee or to a successor Depositary or its
nominee. The rights of Holders of such Global Security shall be exercised only
through the Depositary.

..........A Global Security shall be exchangeable for Series M Notes registered
in the names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as a
Depositary for such Global Security and no successor Depositary shall have been
appointed by the Company, or if at any time the Depositary ceases to be a
clearing agency registered under the Securities Exchange Act of 1934, as
amended, at a time when the Depositary is required to be so registered to act as
such Depositary and no successor Depositary shall have been appointed by the
Company, in each case within 90 days after the Company receives such notice or
becomes aware of such cessation, (ii) the Company in its sole discretion
determines that such Global Security shall be so exchangeable, or (iii) there
shall have occurred an Event of Default with respect to the Series M Notes. Any
Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Series M Notes registered in such names as the Depositary shall
direct.

..........SECTION 106. Transfer. No service charge will be made for any transfer
or exchange of Series M Notes, but payment will be required of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith.

..........The Company shall not be required (a) to issue, transfer or exchange
any Series M Notes except to the Insurer during a period beginning at the
opening of business fifteen (15) days before the day of the mailing of a notice
pursuant to Section 1104 of the Original Indenture identifying the serial
numbers of the Series M Notes to be called for redemption, and ending at the
close of business on the day of the mailing, or (b) to transfer or exchange any
Series M Notes theretofore selected for redemption in whole or in part, except
the unredeemed portion of any Series M Note redeemed in part.

..........SECTION 107. Redemption. The Series M Notes shall be subject to
redemption at the option of the Company, in whole or in part, without premium or
penalty, at any time or from time to time on or after March 1, 2008, at a
Redemption Price equal to 100% of the principal amount to be redeemed plus
accrued but unpaid interest to the Redemption Date.

..........In the event of redemption of the Series M Notes in part only, a new
Series M Note or Notes for the unredeemed portion will be issued in the name or
names of the Holders thereof upon the surrender thereof.

..........The Series M Notes will not have a sinking fund.

..........Notice of redemption shall be given as provided in Section 1104 of the
Original Indenture.

..........Any redemption of less than all of the Series M Notes shall, with
respect to the principal thereof, be divisible by $1,000.

..........SECTION 108. Redemption Upon Death of a Beneficial Owner. On or after
March 1, 2008, unless the Series M Notes have been declared due and payable
prior to the Stated Maturity by reason of an Event of Default, or have been
previously redeemed or otherwise repaid, the Representative (as hereinafter
defined) of a deceased Beneficial Owner (as hereinafter defined) of the Series M
Notes has the right to request redemption prior to the Stated Maturity of all or
part of his or her interest in such Series M Notes and the Company will redeem
the same, subject to the limitations that the Company will not be obligated to
redeem during any twelve-month period that ends on and includes each March 1
after March 1, 2008 (each such twelve-month period being hereinafter referred to
as a "Subsequent Period") (i) on behalf of a deceased Beneficial Owner any
interest in the Series M Notes which exceeds $25,000 aggregate principal amount
or (ii) interests in the Series M Notes exceeding $3,000,000 in aggregate
principal amount for all Representatives requesting redemption upon the death of
Beneficial Owners.

..........The Company may, at its option, redeem interests of any deceased
Beneficial Owner in the Series M Notes in any Subsequent Period in excess of the
$25,000 limitation. Any such redemption by the Company, to the extent that it
exceeds the $25,000 limitation for any deceased Beneficial Owner, shall not be
included in the computation of the $3,000,000 aggregate limitation for the
Series M Notes for such Subsequent Period or for any succeeding Subsequent
Period. The Company may, at its option, redeem interests of deceased Beneficial
Owners in the Series M Notes, in any Subsequent Period in an aggregate principal
amount exceeding the $3,000,000 aggregate limitation. Any such redemption by the
Company, to the extent it exceeds the $3,000,000 aggregate limitation, shall not
reduce the $3,000,000 aggregate limitation for any succeeding Subsequent Period.
Upon any determination by the Company to redeem Series M Notes in excess of the
$25,000 limitation or the $3,000,000 aggregate limitation, such Series M Notes
shall be redeemed in the order of the receipt of Redemption Requests (as
hereinafter defined) by the Trustee.

..........A request for redemption of an interest in the Series M Notes may be
initiated by the personal representative or other person authorized to represent
the estate of the deceased Beneficial Owner or from a surviving joint tenant(s)
or tenant(s) by the entirety or the trustee of a trust (each, a
"Representative"). A Representative may initiate a request for redemption at any
time and in any principal amount, provided that the principal amount is in
integral multiples of $1,000. The Representative shall deliver its request to
the Participant (as hereinafter defined) through whom the deceased Beneficial
Owner owned such interest, in form satisfactory to the Participant, together
with evidence of the death of the Beneficial Owner, evidence of the authority of
the Representative satisfactory to the Participant, any waivers, notices or
certificates as may be required under applicable state or federal law and any
other evidence of the right to such redemption as the Participant requires. The
request shall specify the principal amount of the interest in the Series M Notes
to be redeemed, which amount must be in integral multiples of $1,000. Subject to
the rules and arrangements applicable to the Depositary, the Participant will
then deliver to the Depositary a request for redemption substantially in the
form attached to the Series M Notes as Annex A (a "Redemption Request"). The
Depositary will, upon receipt of a Redemption Request, forward the same to the
Trustee. The Trustee is required to maintain records with respect to Redemption
Requests received by it, including the date of receipt, the name of the
Participant filing the Redemption Request and the status of each Redemption
Request with respect to the $25,000 limitation and the $3,000,000 aggregate
limitation. The Trustee will promptly file with the Company each Redemption
Request it receives, together with the information regarding the eligibility of
the Redemption Request with respect to the $25,000 limitation and the $3,000,000
aggregate limitation. The Company, the Depositary and the Trustee (i) may
conclusively assume, without independent investigation, that the statements
contained in each Redemption Request are true and correct and (ii) shall have no
responsibility (a) for reviewing any documents submitted to the Participant by
the Representative or for determining whether the applicable decedent is in fact
the Beneficial Owner of the interest in the Series M Notes to be redeemed or is
in fact deceased and (b) for determining whether the Representative is duly
authorized to request redemption on behalf of the applicable Beneficial Owner.

..........On or after March 1, 2008 and subject to the $25,000 limitation and the
$3,000,000 aggregate limitation, the Company will, after the death of any
Beneficial Owner, redeem the interest of such Beneficial Owner in the Series M
Notes within 60 days following receipt by the Company of a Redemption Request
from the Trustee. If Redemption Requests exceed the aggregate principal amount
of interests in Series M Notes required to be redeemed during any Subsequent
Period, then such excess Redemption Requests will be applied, in the order
received by the Trustee, to successive Subsequent Periods, regardless of the
number of Subsequent Periods required to redeem such interests. The Company may,
at any time, notify the Trustee that it will redeem, on a date not less than 30
nor more than 60 days after the date of such notice, all or any lesser amount of
Series M Notes for which Redemption Requests have been received but which are
not then eligible for redemption by reason of the $25,000 limitation or the
$3,000,000 aggregate limitation. Such Series M Notes will be redeemed in the
order of receipt of Redemption Requests by the Trustee.

..........The price to be paid by the Company for the Series M Notes to be
redeemed pursuant to a Redemption Request is 100% of the principal amount
thereof plus accrued and unpaid interest to the date of payment. Subject to
arrangements with the Depositary, payment for interests in the Series M Notes to
be redeemed shall be made to the Depositary upon presentation of the Series M
Notes to the Trustee for redemption in the aggregate principal amount specified
in the Redemption Requests submitted to the Trustee by the Depositary which are
to be fulfilled in connection with such payment. The principal amount of any
Series M Notes acquired or redeemed by the Company other than by redemption at
the option of any Representative of a deceased Beneficial Owner pursuant to this
Section 108 shall not be included in the computation of either the $25,000
limitation or the $3,000,000 aggregate limitation for any Subsequent Period.

..........For purposes of this section, a "Beneficial Owner" means the person who
has the right to sell, transfer or otherwise dispose of an interest in a Series
M Note and the right to receive the proceeds therefrom, as well as the interest
and principal payable to the Holder thereof. In general, a determination of
beneficial ownership in the Series M Notes will be subject to the rules,
regulations and procedures governing the Depositary and institutions that have
accounts with the Depositary or a nominee thereof ("Participants").

..........For purposes of this section, an interest in a Series M Note held in
tenancy by the entirety, by joint tenancy or by tenants in common will be deemed
to be held by a single Beneficial Owner, and the death of a tenant by the
entirety, joint tenant or tenant in common will be deemed the death of a
Beneficial Owner. The death of a person who, during his or her lifetime, was
entitled to substantially all of the rights of a Beneficial Owner of an interest
in the Series M Notes will be deemed the death of the Beneficial Owner,
regardless of the recordation of such interest on the records of the
Participant, if such rights can be established to the satisfaction of the
Participant and the Company. Such interests shall be deemed to exist in typical
cases of nominee ownership, ownership under the Uniform Gifts to Minors Act or
the Uniform Transfers to Minors Act, community property or other similar joint
ownership arrangements, including individual retirement accounts or Keogh H.R.
10 plans maintained solely by or for the decedent or by or for the decedent and
any spouse, and trust and certain other arrangements where one person has
substantially all of the rights of a Beneficial Owner during such person's
lifetime.

..........In the case of a Redemption Request that is presented on behalf of a
deceased Beneficial Owner and that has not been fulfilled at the time the
Company gives notice of its election to redeem the Series M Notes pursuant to
Section 107, the Series M Notes that are the subject of such pending Redemption
Request shall not be eligible for redemption pursuant to the Company's option to
redeem but shall remain subject to redemption pursuant to such Redemption
Request.

..........Any Redemption Request may be withdrawn by the person(s) presenting
such request upon delivery of a written request for such withdrawal given by the
Participant on behalf of such person(s) to the Depositary and by the Depositary
to the Trustee prior to the redemption payment by the Company.

..........During any time in which the Series M Notes are not represented by one
or more Global Securities and are issued in definitive form (i) all references
in this Section 108 to Participants and the Depositary, including the
Depositary's governing rules, regulations and procedures will be deemed deleted,
(ii) all determinations which under this Section 108 the Participants are
required to make will be made by the Company (including, without limitation,
determining whether the applicable decedent is in fact the Beneficial Owner of
the interest in the Series M Notes to be redeemed or is in fact deceased and
whether the Representative is duly authorized to request redemption on behalf of
the applicable Beneficial Owner) and (iii) all Redemption Requests, to be
effective, must (a) be delivered by the Representative to the Trustee, with a
copy to the Company, (b) if required by the Trustee and the Company, be in the
form of a Redemption Request (with appropriate changes mutually agreed to by the
Trustee and the Company to reflect the fact that such Redemption Request is
being executed by a Representative (including provision for signature
guarantees)) and (c) in addition to all documents that are otherwise required to
accompany a Redemption Request, shall be accompanied by the Series M Note that
is the subject of such Redemption Request and, if applicable, a properly
executed assignment or endorsement. If the record interest in the Series M Note
is held by a nominee of the deceased Beneficial Owner, a certificate or letter
from such nominee attesting to the deceased's ownership of a beneficial interest
in the Series M Note must also be delivered.


                                    ARTICLE 2

                          Special Insurance Provisions

         SECTION 201. Supplemental Indentures. The consent of the Insurer shall
be required with respect to any indenture or indentures supplemental to the
Original Indenture requiring the consent of the Holders of the Series M Notes
pursuant to Section 902 of the Original Indenture.

         SECTION 202. Events of Default and Remedies. Subject to Section 107 of
the Original Indenture and to the Trust Indenture Act, including, without
limitation, Sections 316(a)(1) and 317(a) thereof, if an Event of Default occurs
and is continuing, the Insurer shall be entitled to control and direct the
enforcement of all rights and remedies granted to the Holders of the Series M
Notes or the Trustee for the benefit of the Holders of the Series M Notes under
this Indenture, including, without limitation, (i) the right to accelerate the
principal of the Series M Notes as provided in Section 502 of the Original
Indenture, and (ii) the right to annul any such declaration of acceleration, and
the Insurer shall also be entitled to approve any waiver of an Event of Default
with respect to the Series M Notes, the obligation of the Trustee to comply with
any such direction to be subject to compliance with the conditions set forth in
Sections 512 and 603(e) of the Original Indenture (as if references in those
Sections to Holders were references to the Insurer) and the protections provided
to the Trustee by Section 601(c)(3) of the Original Indenture shall be
applicable with respect to any direction from the Insurer given pursuant hereto
(as if references in said Section to Holders were references to the Insurer).

         SECTION 203. Insurance Policy Payment Procedures. (a) The Insurer will
make payments of principal or interest due on the Series M Notes in accordance
with the Policy on or before the first Business Day next following the date on
which the Insurer shall have received notice of Nonpayment (as defined in the
Policy) from the Trustee.

         (b)......In the event of Nonpayment and notification thereof to the
Insurer, the Trustee shall make available to the Insurer the books kept by the
Trustee for the registration and for the registration of transfer of Series M
Notes as provided in this Indenture.

         (c)......The Trustee shall, at the time it provides notice to the
Insurer pursuant to (a) above, notify Holders of Series M Notes entitled to
receive the payment of principal or interest thereon from the Insurer (i) as to
the fact of such entitlement, (ii) that the Insurer will remit to them all or a
part of the interest payments next coming due upon proof of Holder entitlement
to interest payments and delivery to the Insurer, in form satisfactory to the
Insurer, of an appropriate assignment of the Holder's right to payment, (iii)
that should they be entitled to receive full payment of principal from the
Insurer, they must surrender their Series M Notes (along with an appropriate
instrument of assignment in form satisfactory to the Insurer to permit ownership
of such Series M Notes to be registered in the name of the Insurer) for payment
to the Insurer, and not the Trustee or any paying agent, and (iv) that should
they be entitled to receive partial payment of principal from the Insurer, they
must surrender their Series M Notes for payment thereon first to the Trustee,
who shall note on such Series M Notes the portion of the principal paid by the
Trustee, and then, along with an appropriate instrument of assignment in form
satisfactory to the Insurer, to the Insurer, which will then pay the unpaid
portion of principal.

         (d)......In the event that the Trustee has notice that any payment of
principal of or interest on a Series M Note which has become due for payment
(under the terms of the Policy) and which is made to a Holder by or on behalf of
the Company has been deemed a preferential transfer and theretofore recovered
from its Holder pursuant to the United States Bankruptcy Code by a trustee in
bankruptcy in accordance with a final, nonappealable order of a court having
competent jurisdiction, the Trustee shall, at the time the Insurer is notified
pursuant to (a) above, notify all Holders of the Series M Notes that in the
event that any Holder's payment is so recovered, such Holder will be entitled to
payment from the Insurer to the extent of such recovery if sufficient funds are
not otherwise available, and the Trustee shall furnish to the Insurer its
records evidencing the payments of principal of and interest on the Series M
Notes which have been made by the Trustee and subsequently recovered from
Holders and the dates on which such payments were made.

         (e)......In addition to those rights granted the Insurer under this
Indenture, the Insurer shall, to the extent it makes payment of principal of or
interest on Series M Notes, become subrogated to the rights of the recipients of
such payments in accordance with the terms of the Policy, and to evidence such
subrogation (i) in the case of subrogation as to claims for past due interest,
the Trustee shall note the Insurer's rights as subrogee on the registration
books of the Company maintained by the Trustee upon receipt from the Insurer of
proof of the payment of interest thereon to the Holders of the Series M Notes,
and (ii) in the case of subrogation as to claims for past due principal, the
Trustee shall note the Insurer's rights as subrogee on the registration books of
the Company maintained by the Trustee upon surrender of the Series M Notes by
the Holders thereof together with proof of the payment of principal thereof.

         SECTION 204. Application of Term "Outstanding" to Series M Notes. In
the event that the principal and/or interest due on the Series M Notes shall be
paid by the Insurer pursuant to the Policy, the Series M Notes shall remain
Outstanding for all purposes of this Indenture, not be considered defeased or
otherwise satisfied and not be considered paid by the Company, and the
assignment and pledge of this Indenture and all covenants, agreements and other
obligations of the Company to the Holders of the Series M Notes shall continue
to exist and shall run to the benefit of the Insurer, and the Insurer shall be
subrogated to the rights of such Holders to the extent of each such payment.

         SECTION 205. Insurer as Third Party Beneficiary. To the extent that
this Indenture confers upon or gives or grants to the Insurer any right, remedy
or claim under or by reason of this Indenture, the Insurer is hereby explicitly
recognized as being a third-party beneficiary hereunder and may enforce any such
right, remedy or claim conferred, given or granted hereunder.

         SECTION 206. Concerning the Special Insurance Provisions. The
provisions of this Article 2 shall apply notwithstanding anything in this

made on the next succeeding day that is a Business Day (and without interest or
other payment in respect of any such delay), with the same force and effect as
if made on the date the payment was originally payable. A "Business Day" shall
mean any day other than a Saturday or a Sunday or a day on which banking
institutions in New York City are authorized or required by law or executive
order to remain closed or a day on which the Corporate Trust Office of the
Trustee is closed for business.

earlier redemption of the Series M Notes shall be made upon surrender of the

Interest Payment Date) will be made, subject to such surrender where applicable,
at the option of the Company, (i) by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register or (ii)
by wire transfer at such place and to such account at a banking institution in
the United States as may be designated in writing to the Trustee at least 16
days prior to the date for payment by the Person entitled thereto.

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.
