         THIS INDENTURE OF TRUST (the "Indenture"), dated as of November 1,
1999, made and entered into by and between the DEVELOPMENT AUTHORITY OF HEARD
COUNTY, a public corporation created and existing under the laws of the State of
Georgia (the "Issuer"), and THE CHASE MANHATTAN BANK, a state banking
corporation duly organized and existing under and by virtue of the laws of the
State of New York, having power and authority to accept and execute trusts, and
having its principal office in New York, New York, as Trustee (the "Trustee"),

                                    RECITALS

         WHEREAS, the Issuer has been created pursuant to the provisions of an
Act of the General Assembly of the State of Georgia (O.C.G.A. Section 36-62), as
amended and an activating resolution of the Board of Commissioners of Heard
County, Georgia duly adopted on January 3, 1972 (collectively, the "Act"), its
directors have been appointed as provided in the Act and are currently acting in
such capacity; and

         WHEREAS, the Issuer has been created for the purpose of encouraging and
promoting the expansion and development of industrial and commercial facilities
in Heard County, Georgia; the Act empowers the Issuer to issue its revenue
obligations, in accordance with the applicable provisions of the Revenue Bond
Law of the State of Georgia (O.C.G.A. Sections 36-82-60 to 36-82-85), as
heretofore and hereafter amended, for the purpose of financing any undertaking
within the scope of its power, including, without limitation, the acquisition by
purchase or gift of any building or structure within the territorial limits of
Heard County suitable for and intended for use as a factory, mill, shop,
processing plant, assembly plant or fabricating plant, including all appurtenant
lands and appurtenances thereto and all necessary or useful furnishings,
machinery and equipment, and the lease or sale of such building or structure for
operation by one or more persons, firms or corporations, all in furtherance of
the public purpose for which it was created; and

         WHEREAS, after careful study and investigation the Issuer, in
furtherance of the purpose for which it was created and pursuant to a resolution
duly adopted, has entered into a lease agreement (as the same may be amended
from time to time in accordance with its terms, the "Lease Agreement"), dated as
of even date herewith, with Tenaska Georgia Partners, L.P. (the "Lessee"), a
limited partnership organized and existing under the laws of the State of
Delaware, and duly qualified to do business in the State of Georgia, pursuant to
which the Issuer has agreed to acquire, construct and install the Project (as
defined in the Lease Agreement), including the real property owned by the Issuer
for the exclusive use and occupancy of the Lessee under the Lease Agreement and
the Lessee has agreed to pay the Issuer specified rental payments and other
payments; and

         WHEREAS, after careful investigation, the Issuer has found and does
hereby declare that it is in the best interest of the citizens of Heard County
that the Project be acquired, constructed and installed and leased to the Lessee
for the purposes stated in the Lease Agreement, all in keeping with the public
purpose for which the Issuer was created, and that such acquisition,

                                      A-1

construction and installation of the Project and lease thereof to the Lessee are
specifically authorized under the Act; and

         WHEREAS, a Project Summary (the "Project Summary") for the Project has
been prepared by the Lessee, and it is estimated that the amount necessary to
finance the cost of the Project, including expenses incidental thereto, will not
exceed $400,000,000 (said Project Summary, a copy of which is attached to the
Lease Agreement as Exhibit C and which may be amended from time to time by the
Lessee, has been approved by the Issuer and is on file with the Secretary of the
Issuer); and

         WHEREAS, the most feasible method of financing the cost of the Project
is through the issuance hereunder of Development Authority of Heard County

$400,000,000 (the "Series 1999 Bonds"); and

         WHEREAS, the execution and delivery of this Indenture and the sale,
issuance and delivery of the Series 1999 Bonds have been in all respects duly
and validly authorized by resolution duly adopted by the Issuer; and

         WHEREAS, it is anticipated that additional moneys may be necessary to
finance the cost of (a) completing the acquisition, construction and
installation of the Project, (b) providing for the enlargement, improvement,
expansion or replacement of the Project, (c) refunding all of the Bonds of any
one or more series then outstanding, or (d) any combination of the foregoing,
and provision should be made for the issuance from time to time of Additional
Bonds which shall be equally and ratably secured hereunder with the Series 1999
Bonds (the Series 1999 Bonds and such Additional Bonds being hereinafter
collectively referred to as the "Bonds"); and

         WHEREAS, the Series 1999 Bonds will be delivered to and paid for by
Tenaska Georgia Partners, L.P., as purchaser (the "Purchaser") to finance the
acquisition, construction and installation of the Project, and the provisions of
this Indenture are to be liberally read and construed in a manner which
facilitates such approach to delivery and payment; and

         WHEREAS, the Issuer will receive rental payments and other payments
from the Lessee, which revenues, together with all other rents, revenues and
receipts and other payments to be received pursuant to the Lease Agreement,
shall be pledged together with the Lease Agreement (except for the Unassigned
Rights) as security for the payment of the principal of and interest on the
Bonds; and

         WHEREAS, as additional security for the payment of the Bonds, the
Issuer has conveyed title to that portion of the Project consisting of real
property and has assigned all leases in and to all rents and other payments
derived from the Project and has granted a security interest in that portion of
the Project consisting of personal property to the Trustee pursuant to the terms

or modified in accordance with its terms, the "Common Agreement") which sets
forth certain representations, warranties and covenants of the Issuer and the

         WHEREAS, the Lessee, the Trustee, the Senior Parties, The Chase

Manhattan Bank, as the depositary bank (the "Depositary Bank"), have entered
into a Collateral Agency and Intercreditor Agreement dated November 1, 1999 (as
amended or modified in accordance with its terms, the "Collateral Agency

generated and distributed to the Lessee;

         WHEREAS, the Trustee recites that a condition of its acceptance of this
Indenture is the receipt of a duly authorized, executed and delivered Guaranty
Agreement, dated as of even date herewith, pursuant to which the Lessee, as
guarantor, absolutely and unconditionally guarantees to it the full and prompt

and interest on the Series 1999 Bonds; and

         WHEREAS, all things necessary to make the Series 1999 Bonds, when

of the Bonds shall be equally and ratably secured by this Indenture by the
pledge herein made, it being expressly understood and agreed that no Bonds

but shall be on a parity therewith, with respect to the liens and security
interests created in favor of the Trustee under this Indenture.

         SECTION 2.02. DATES AND PLACES OF PAYMENT OF BONDS. Each series of the
Bonds shall bear such date as shall be specified in this Indenture or in the

such dates in such years and in such amounts as shall be fixed therefor prior to
its issuance. Interest on the Bonds from their

                                      A-8
<PAGE>

respective dates until their respective maturities shall be payable at such
rates as shall be fixed therefor prior to their issuance.

provided.

         Each Bond shall be dated the date of its authentication and delivery by

paid or provided for, unless: (1) the date of authentication of such Bond is an

Bond, in which case from the dated date of such Bond or (3) such authentication
date shall be after any Record Date and before the next succeeding Interest
Payment Date in which case interest shall be paid from the next succeeding
Interest Payment Date.

         The principal of and interest on each of the Bonds shall be payable in
lawful money of the United States of America by check payable to the owner
thereof delivered at the address of such owner as shown on the bond register
maintained by the Trustee as Bond Registrar (the "Bond Register"), unless there
shall be in effect a home office payment agreement satisfactory to the Trustee,
as provided in Section 2.08 hereof. Such payments shall be made to the person in
whose name a Bond shall be registered on the Bond Register, with respect to
payment of principal, on the date such principal is due, and, with respect to

Register. Payment of the final installment of principal of each Bond to the
owner thereof shall be made upon surrender of the Bond to the Trustee. The Bond
Registrar shall maintain a record of the amount and date of all payments or
prepayment of the principal of and interest on the Bonds.

         SECTION 2.03. EXECUTION; LIMITED OBLIGATION. The Bonds shall be
executed on behalf of the Issuer by the official manual or facsimile signature
of its Chairman or Vice Chairman and the Issuer's corporate seal shall be
affixed thereto or printed thereon and attested by the official manual or
facsimile signature of its Secretary or Assistant Secretary. The obligation of
the Issuer to pay the Bonds and the interest thereon shall not be a general
obligation of the Issuer but shall be a limited obligation which shall be
payable from, and wholly secured by, a pledge of the Trust Estate. If any
officer of the Issuer who shall have signed or sealed any Bonds shall cease to
be such officer before such Bond so signed and/or sealed has been authenticated
and delivered by the Trustee, such Bond nevertheless may be authenticated and
delivered as though the person who signed and/or sealed such Bond had not ceased
to be such officer, and also any Bond may be signed and sealed on behalf of the
Issuer by such persons as at the actual time of execution of such Bond shall be
the proper officers of the Issuer, although at the date of such Bond such
persons may not have been officers of the Issuer.

         SECTION 2.04. AUTHENTICATION. Only such Bonds as shall have endorsed
thereon a certificate of authentication substantially in the form hereinafter
set forth duly executed by the Trustee shall be entitled to any right or benefit
under this Indenture. No Bond shall be valid or obligatory for any purpose
unless and until such certificate of authentication shall have been duly
executed by the Trustee, and such executed certificate of the Trustee upon any
such Bond shall be conclusive evidence that such Bond has been authenticated and
delivered under this Indenture. Said certificate of authentication on any Bond
shall be deemed to have been executed

                                      A-9
<PAGE>

by the Trustee if signed by an authorized signatory of the Trustee, but it shall
not be necessary that the same signatory sign the certificate of authentication
on all of the Bonds issued hereunder.

         SECTION 2.05. FORM OF BONDS. The fully registered Series 1999 Bonds and
the form for transfer and the validation certificate to be printed thereon, and
the Trustee's certificate to be endorsed on all Series 1999 Bonds shall be in
substantially the form hereinafter set forth in Exhibit "A" hereto with such
appropriate variations, omissions, substitutions and insertions as are permitted
or required by this Indenture and may have such letters, numbers or other marks
of identification and such legends and endorsements placed thereon, as may be
required to comply with any applicable laws or rules or regulations, or as may,
consistently herewith, be determined by the officers executing such Series 1999
Bonds, as evidenced by their execution of the Series 1999 Bonds. The Bonds of
each series of Additional Bonds, and the various certificates to be endorsed
thereon shall be in substantially the forms respectively provided therefor in
the supplemental indenture under which each series of Additional Bonds is
issued, which forms shall in general be similar to the form applicable to the
Series 1999 Bonds, with such insertions, omissions and other variations as may
be necessary to conform to the provisions hereof and of such supplemental
indenture.

         SECTION 2.06. MUTILATED, LOST, STOLEN OR DESTROYED BONDS. If any Bond
is mutilated, lost, stolen or destroyed, the Issuer may execute and the Trustee
may authenticate and deliver a new Bond in the same principal amount in lieu of
and in substitution for the Bond mutilated, lost, stolen or destroyed; provided
that, in the case of any mutilated Bond, such mutilated Bond shall first be
surrendered to the Trustee, and in the case of any lost, stolen or destroyed
Bond, there shall be first furnished to the Issuer and the Trustee evidence
satisfactory to them and to the Lessee of the ownership of such Bond and of such
loss, theft or destruction, together with indemnity satisfactory to them. If any
such Bond shall have fully matured, instead of issuing a new Bond the Issuer may
pay the same. The Issuer and the Trustee may charge the owner of such Bond with
their reasonable fees and expenses in this connection.

         SECTION 2.07. TRANSFER OF BONDS; PERSONS TREATED AS OWNERS. The Issuer
shall cause books for the transfer of the Bonds as provided in this Indenture to
be kept by the Trustee which is hereby constituted and appointed the Bond
Registrar of the Issuer. Upon surrender for transfer of any Bond at the
Principal Office of the Trustee, the Issuer shall execute and the Trustee shall
authenticate and deliver in the name of the transferee or transferees a new
fully registered Bond or fully registered Bonds in the same aggregate principal
amount of any authorized denomination or denominations. Fully registered Bonds
may be exchanged at the Principal Office of the Trustee for an equal aggregate
principal amount of fully registered Bonds of any authorized denomination or
denominations.

         Any Bond shall be fully transferable by the registered owner on the
Bond Register to be provided for that purpose, upon presentation of such Bond
for notation of transfer thereof at the Principal Office of the Trustee, as Bond
Registrar, accompanied by a written instrument of transfer in form satisfactory
to the Bond Registrar duly executed by the registered owner or its attorney duly
authorized in writing. No service charge shall be made for any such transfer,
but the Bond Registrar may require payment of a sum sufficient to cover any tax
or other governmental charge payable in connection therewith. The person in
whose name any Bond is registered from time to time shall be deemed and regarded
as the absolute owner thereof for all

                                      A-10
<PAGE>

purposes and payment of or on account of the principal of and interest on such
Bond shall be made only to or upon the order of the registered owner thereof, or
its attorney duly authorized in writing, and neither the Issuer, the Trustee
(acting in its capacity as Bond Registrar or otherwise), nor any paying agent
acting for the Issuer shall be affected by any notice to the contrary. All such
payments shall be valid and effectual to satisfy and discharge the liability
upon the Bonds to the extent of the sum or sums so paid.

         Anything in this Indenture to the contrary notwithstanding, there shall
not be effected, and the Trustee acting as Bond Registrar shall not permit the
effecting of, any transfer of any Bond pursuant to the provisions of this
Section, unless there is delivered to the Trustee (except for a transfer under
and pursuant to the Partnership Assignment and Security Agreement) an opinion of
Counsel satisfactory to the Trustee, the Issuer and the Lessee to the effect
that such transfer will not violate applicable securities laws.

         All Bonds which have been surrendered to the Trustee pursuant to
Section 2.06 or 2.07 of this Indenture or for the purpose of payment upon
maturity or prepayment prior to maturity shall be cancelled and destroyed by the
Trustee and a certificate of destruction shall be delivered to the Issuer upon
the Issuer's request.

         SECTION 2.08. HOME OFFICE PAYMENT AGREEMENT. Notwithstanding any
provision of this Indenture or of any Bond to the contrary, the Issuer and the
Trustee may enter into a home office payment agreement with the owner of any
Bond in an original principal amount of at least $100,000, providing for the
making to such owner of all payments of principal and interest on such Bond or
any part thereof (other than any payment of the entire unpaid principal amount
thereof) at a place and in a manner other than as provided in this Indenture and
in the Bonds without presentation or surrender of such Bond, upon such
conditions as shall be satisfactory to the Trustee (including the payment by the
Lessee of rental payments under the Lease directly to the owners of the Bonds in
satisfaction of the principal and interest on the Bonds). The Trustee agrees to
make or permit to be made payments of principal and interest on the Bonds in
accordance with the provisions of such home office payment agreement. The
Trustee shall not be liable to any such owner or to the Issuer for any act or
omission to act on the part of the Issuer, any such owner or any agent of the
Issuer, in connection with any such agreement, and the Trustee shall have no
obligation in connection with any payment of principal or interest made in
compliance with any such agreement and shall not be deemed to have notice of any
default in the making of any such payment. Upon the transfer of any registered
Bond being paid in accordance with the provisions of a home office payment
agreement permitted by this Section, the owner of such registered bond prior to
the delivery of such Bond to the transferee, shall make a notation on such Bond
of the date to which interest has been paid thereon and the amount of any
prepayments made on account of the principal thereof, and the Trustee shall not
be deemed to have notice of any such payment.

         SECTION 2.09. REDEMPTION OF BONDS. The Series 1999 Bonds shall be
subject to redemption prior to maturity as set forth in Article III hereof, and
any series of Additional Bonds issued hereunder shall be subject to redemption
prior to maturity as provided in the supplemental indenture relating thereto.

                                      A-11
<PAGE>

SECTION 2.10. PROCEDURE FOR REDEMPTION OF BONDS. The Issuer and the Trustee
shall take all action necessary to effect the redemption of Bonds as herein
provided upon the receipt by the Trustee, at least 10 days prior to the date
fixed for redemption, of a certificate of the Lessee specifying the proposed
redemption date, the principal amount of the Bonds to be called for redemption,
the applicable redemption price or prices and the provision or provisions of
this Indenture pursuant to which such Series 1999 Bonds are to be called for
redemption.

         SECTION 2.11. SELECTION OF BONDS TO BE REDEEMED; PARTIAL REDEMPTION OF
BONDS.

                  (a) If less than all of the Bonds are to be redeemed, the
         Bonds to be redeemed shall be selected by the Trustee by lot.

                  (b) In the case of any redemption of Bonds of denominations
         greater than $100,000, if less than all of such Bonds then outstanding
         are to be called for redemption, then for all purposes in connection
         with such redemption, each $100,000 of face value shall be treated as
         though it were a separate Bond of the denomination of $100,000. If it
         is determined that one or more, but not all of the $100,000 units of
         face value represented by any Bond are to be called for redemption,
         then, upon notice of intention to redeem such $100,000 unit or units,
         the owner of such Bond shall forthwith surrender such Bond to the
         Trustee (1) for payment of the redemption price of the $100,000 unit or
         units of face value called for redemption and (2) in exchange for a new
         Bond or Bonds of the aggregate principal amount of the unredeemed
         balance of the principal amount of such Bond. New Bonds representing
         the unredeemed balance of the principal amount of such Bond shall be
         issued to the registered owner thereof without charge therefor. If the
         owner of any such Bond of a denomination greater than $100,000 shall
         fail to present such Bond to the Trustee for payment and exchange as
         aforesaid, such Bond shall, nevertheless, become due and payable on the
         date fixed for redemption to the extent of the $100,000 unit or units
         of face value called for redemption (and to that extent only); interest
         shall cease to accrue on the portion of the principal amount of such
         Bond represented by such $100,000 unit or units of face value on and
         after the date fixed for the redemption; and, provided funds sufficient
         for the payment of the redemption price have been deposited with the
         Trustee and are available for the redemption of said $100,000 unit or
         units on the date fixed for redemption, such Bond shall not be entitled
         to the benefit or security of this Indenture to the extent of the
         portion of its principal amount (and accrued interest thereon to the
         date fixed for redemption) represented by such $100,000 unit or units
         of face value, nor shall new Bonds be thereafter issued corresponding
         to such $100,000 unit or units.

         SECTION 2.12. NOTICE OF REDEMPTION. Notice of the call for redemption
identifying the Bonds to be redeemed shall be given by the Trustee by mailing a
copy of the redemption notice by first class mail, postage prepaid, not less
than 10 nor more than 60 days prior to the redemption date to the registered
owner of each Bond to be redeemed, in whole or in part, at the address shown on
the Bond Register. Any notice mailed as provided in this Section shall be
conclusively presumed to have been duly given, whether or not the owner receives
such notice.

                                      A-12
<PAGE>

         Each notice of redemption shall specify the date fixed for redemption,
the CUSIP number or numbers of the Bonds to be redeemed, the principal amount of
the Bonds or portions thereof to be redeemed, the redemption price or prices,
the place or places of payment, that redemption of the Bonds is contingent upon
the satisfaction of certain conditions or the occurrence of certain events (if
any) specified by the Lessee, that payment will be made upon presentation and
surrender of the Bonds to be redeemed (provided that the Bonds are not held in
book-entry only form), that interest accrued to the date fixed for redemption
will be paid as specified in said notice, and that on and after said date
interest thereon will cease to accrue. If less than all the outstanding Bonds
are to be redeemed, the notice of redemption shall specify the numbers of the
Bonds to be redeemed. In case any Bond is to be redeemed in part only, the
notice of redemption shall state that on and after the date fixed for
redemption, upon surrender of such Bond, a new Bond or Bonds in principal amount
equal to the unredeemed portion thereof will be issued without charge therefor.

         Failure to give any such notice by mailing, or any defect therein,
shall not affect the validity of any proceedings for the redemption of any Bond
as to which notice was given as provided herein.

         If the Lessee specifies any conditions to such redemption, unless all
conditions to redemption specified in the notice of redemption shall have been
satisfied or waived by the Lessee, such notice shall be of no force and effect,
the Issuer and the Trustee shall not redeem such Bonds and the bond registrar
shall promptly return the Bonds it has received to the registered owners thereof
as shown on the registration books. The Trustee may conclusively rely upon a
certificate of the Authorized Lessee Representative as to the satisfaction or
waiver of any conditions specified to any such redemption.

         SECTION 2.13. ADDITIONAL NOTICE OF REDEMPTION. In the event any Bond to
be redeemed is registered in the name of any person other than the Purchaser,
further notice of redemption of such Bonds shall be given by the Trustee as set
out below, but no defect in said further notice nor any failure to give all or
any portion of such further notice shall in any manner defeat the effectiveness
of a call for redemption if notice thereof is given as prescribed in Section
2.14.

         Each further notice of redemption given hereunder shall contain the
information required in Section 2.14 for an official notice of redemption, plus
(i) the CUSIP numbers of all Bonds being redeemed (if not included pursuant to
the notice required by Section 2.14); (ii) the date of issue of the Bonds as
originally issued; (iii) the rate of interest borne by each Bond being redeemed;
(iv) the maturity date of each Bond being redeemed; and (v) any other
descriptive information needed to identify accurately the Bonds being redeemed.

         Each further notice of redemption shall be sent at least 30 days before
the redemption date by registered or certified mail or overnight delivery
service (at the expense of the addressee) to all of the following registered
securities depositories then in the business of holding substantial amounts of
bonds of the type comprising the Bonds (such depositories now being Depository
Trust Company of New York, New York; Midwest Securities Trust Company of
Chicago, Illinois; and Philadelphia Depository Trust Company of Philadelphia,
Pennsylvania) and to one or more national information services that disseminate
notices of redemption of bonds

                                      A-13
<PAGE>

such as the Bonds (such as Financial Information Inc.'s Financial Daily Called
Bond Service; Interactive Data Corporation's Bond Service; Kenny Information
Service's Called Bond Service; Moody's Investors Services Municipal and
Government and Standard & Poor's Called Bond Record).

         Upon the payment of the redemption price of Bonds being redeemed, each
check or other transfer of funds issued for such purpose shall bear the CUSIP
number identifying, by issue and maturity, the Bonds being redeemed with the
proceeds of such check or other transfer.

         SECTION 2.14. PAYMENT OF REDEMPTION PRICE; EFFECT OF CALL FOR
REDEMPTION. On or before the redemption date specified in the notice of
redemption, an amount of money sufficient (together with any moneys available
therefor in the Bond Fund) to redeem all the Bonds or portions thereof called
for redemption at the appropriate redemption price, including accrued interest
to the date fixed for redemption, shall be deposited with the Trustee. On the
date designated for redemption, if all conditions specified in such notice have
been satisfied, notice having been given and moneys for payment of the
redemption price being on deposit with the Trustee or any paying agents, the
Bonds or portions thereof so called for redemption shall cease to bear interest;
shall cease to be entitled to any benefit or any security under this Indenture;
and the registered owners thereof shall have no rights in respect to such Bonds
or such portions thereof so called for redemption except to receive payment of
the redemption price therefor and accrued interest thereon to the redemption
date from the moneys on deposit with the Trustee or any paying agents pursuant
to the provisions of this Section.

                               REVENUES AND FUNDS

     SECTION 6.01. SOURCE OF PAYMENT OF BONDS. The obligation of the Issuer
to pay the principal of and interest on the Bonds is not a general obligation
of the Issuer but is a limited obligation payable solely from the rental
payments and other payments received from the Lessee under the Lease
Agreement together with all other rents, revenues and receipts (except for
certain indemnification rights provided therein) arising out of or in
connection with the Issuer's ownership of the Project and as authorized and
provided herein.

         The Project has been leased under the Lease Agreement and the rental
payments provided for in Section 5.3 of the Lease Agreement are to be remitted
directly to the Trustee for the account of the Issuer and are to be deposited in
the Bond Fund (except as may be otherwise provided in a home office payment
agreement authorized by the provisions of Section 2.08 hereof). Said rental
payments are sufficient in amount and become due in a timely manner so as to
insure the prompt payment of the principal of and interest on the Bonds.

         The Bond Purchase Agreement contains a home office payment agreement in
satisfaction of the requirements of Section 2.08 hereof.

         The Lessee has also executed the Guaranty Agreement wherein the Lessee,
as guarantor, has absolutely and unconditionally guaranteed the full and prompt
payment of the principal of and interest on the Bonds.

     SECTION 6.02. CREATION OF THE BOND FUND. There is hereby created by the
Issuer and ordered established with the Trustee a trust fund to be designated
"Development Authority of Heard County Bond Fund - Tenaska Georgia Partners,
L.P. Project, Series 1999", which shall be used to pay the principal of and
interest on the Bonds. There shall be established as trust accounts within
the Bond Fund a General Account and a Special Account. The Special Account
may be established by the Trustee for bookkeeping purposes only and moneys
designated as being held in the Special Account may be held in any segregated
account designated by the Trustee for such purpose. Any reference in this
Indenture to "Bond Fund" without further qualification or explanation shall
constitute a reference to said General Account.

     SECTION 6.03. PAYMENTS INTO THE BOND FUND. There shall be paid into the
Bond Fund, as and when received, (a) all rental payments specified in Section
5.3 of the Lease Agreement (except for any moneys paid directly to the owner
of a fully registered Bond pursuant to the provisions at a home office
payment agreement permitted pursuant to Section 2.08 above

                                      A-22
<PAGE>

and described in Section 6.01 above), (b) all moneys, if any, required to be so
deposited from the Construction Fund as provided in the Collateral Agency
Agreement, (c) all other moneys received by the Trustee under and pursuant to
any of the provisions of the Lease Agreement, the Collateral Agency Agreement,
the Security Deed or this Indenture which are required or which are accompanied
by directions that such moneys are to be paid into the Bond Fund, and (d) any
moneys received from the Lessee, as guarantor pursuant to the Guaranty
Agreement.

         The Issuer covenants that so long as any of the Bonds are outstanding
it will pay, or cause to be paid, into the Bond Fund from the sources of payment
described in Section 6.01 hereof sufficient moneys to promptly pay the principal
of and interest on the Bonds as the same become due and payable. Nothing herein
shall be construed as requiring the Issuer to operate the Project or to use any
funds from any source to pay the principal of and interest on the Bonds or to
pay the costs of maintaining and insuring the Project other than rents, revenues
and receipts arising out of or in connection with its ownership of the Project.

     SECTION 6.04.     USE OF MONEYS IN THE BOND FUND.

          (a) Except as provided in Section 6.09 hereof, moneys in the Bond
     Fund shall be used solely for the payment of the principal of and interest
     on the Bonds. No part of the rental payments under the Lease Agreement
     required to be paid into the Bond Fund (excluding prepayments under
     Section 9.5 of the Lease Agreement) shall be used to redeem, prior to
     maturity, a portion of any Bond; provided, that whenever the moneys held
     in the Bond Fund (in the General Account and in the Special Account) from
     any source whatsoever are sufficient to redeem or otherwise pay all of the
     Bonds and to pay interest to accrue thereon prior to such redemption or
     other payment, the Issuer agrees to take and cause to be taken the
     necessary steps to redeem all of the Bonds from the sources herein
     provided on the next succeeding redemption date for which the required
     redemption notice can be given; and, provided further, that any moneys in
     the Bond Fund other than rental payments may, at the direction of the
     Lessee, be used to redeem a portion of the Bonds so long as the Lessee is
     not in default with respect to any rental payments under the Lease
     Agreement.

          (b) At the maturity date or redemption date prior to maturity of each
     Bond the Trustee shall transfer from the General Account in the Bond Fund
     to the Special Account in the Bond Fund sufficient moneys to pay the
     principal or redemption price of and interest then due and payable with
     respect to each such Bond. Moneys so transferred into said Special Account
     shall not thereafter be invested in any manner but shall be held by the
     Trustee without liability on the part of the Trustee or the Issuer for
     interest thereon until actually paid out for the purposes intended.

         The Issuer hereby authorizes and directs the Trustee to withdraw, from
time to time, sufficient moneys from the Special Account in the Bond Fund to pay
the principal or redemption price of and interest on the Bonds as the same
become due and payable, which authorization and direction the Trustee hereby
accepts.

     SECTION 6.05. CUSTODY OF THE BOND FUND. The Bond Fund shall be held by the
Trustee as a trust fund for the benefit of the owners of the Bonds. The General
Account and the Special Account established in the Bond Fund shall constitute
trust accounts.

     SECTION 6.06. NON-PRESENTMENT OF BONDS AT MATURITY. If any Bond shall not
be presented for payment when the principal thereof becomes due, either at
maturity or at the prepayment date, provided moneys sufficient to pay such Bond
shall have been made available to the Trustee and are held in the Special
Account in the Bond Fund for the benefit of the owner thereof, all liability of
the Issuer to the owner thereof for the payment of such Bond shall forthwith
cease, determine and be completely discharged, and thereupon it shall be the
duty of the Trustee to hold such moneys in said Special Account, without
liability for interest thereon, for the benefit of the owner of such Bond who
shall thereafter be restricted exclusively to moneys held in said special
account, for any claim of whatever nature on his part under this Indenture or
on, or with respect to, such Bond.

     SECTION 6.07. TRUSTEE'S FEES, CHARGES AND EXPENSES. Pursuant to the terms
of the Lease Agreement the Lessee has agreed to pay directly to the Trustee,

as Trustee, paying agent and Bond Registrar and its expenses incurred under this
Indenture, as and when the same become due, (ii) the reasonable fees and
expenses of Trustee's Counsel, as and when the same become due. It is further
understood and agreed that the initial or acceptance fees of the Trustee and the
fees, charges and expenses of the Trustee and Trustee's Counsel referred to in

obligated to pay the same, will be paid to the Trustee, as and when the same
shall become due, as set forth in Section 4.3 of the Lease Agreement.

     SECTION 6.08. MONEYS TO BE HELD IN TRUST. All moneys, if any, paid over to
the Trustee for the account of the Bond Fund under any provision of this
Indenture shall be held in trust by the Trustee for the benefit of the owners of
the Bonds entitled to be paid therefrom.

     SECTION 6.09. REPAYMENT TO THE LESSEE FROM THE BOND FUND.

          (a) Any moneys remaining in the General Account in the Bond Fund after
     payment in full of all Bonds (taking into consideration that sufficient
     moneys or obligations such as are described in Section 10.02 hereof have
     been transferred to and/or deposited in the Special Account in the Bond
     Fund to pay all principal of and interest then due and payable with respect
     to each Bond not yet presented for payment and to pay all principal and
     interest relating to each Bond which is not yet due and payable but with
     respect to which the lien of this Indenture has been defeased upon
     compliance with Article X hereof) and of the fees, charges and expenses of
     the Trustee, any paying agents and the Bond Registrar which have accrued

               principal amount thereof or the interest earnings thereon (said
               earnings to be held in trust also), be sufficient, together with
               any moneys referred to in subsection (i) above, for the payment
               at their respective maturities or prepayment dates prior to
               maturity, of the principal thereof, together

                                      A-27

          and bond registrar) due or to become due in connection with the
          payment or prepayment of the Bonds.

     SECTION 10.03. DISCHARGE OF THE INDENTURE. Notwithstanding the fact that
the lien of this Indenture upon the Trust Estate may have been discharged and

hereof, is hereby defined as and declared to be and to constitute an "event of
default" under this Indenture.

the Trustee may, with the written consent of the Collateral Agent, and shall,
upon written direction of the Collateral Agent, by notice to the Issuer, declare
the entire unpaid principal of and interest on the Bonds due and payable; and
upon such declaration, the said principal, together with interest accrued
thereon, shall become payable immediately at the place of payment provided
therein, anything in this Indenture or in the Bonds to the contrary
notwithstanding. Upon any declaration of acceleration hereunder, the Trustee
shall immediately declare all rental payments due under the Lease Agreement to
be immediately due and payable in accordance with Section 10.2 of the Lease
Agreement.

     SECTION 11.03. SURRENDER OF POSSESSION OF PROJECT; RIGHTS AND DUTIES OF
TRUSTEE IN POSSESSION. Upon the occurrence of an event of default the Lessee,
upon demand of the Trustee in accordance with the instruction of the Collateral
Agent, shall forthwith surrender the

<PAGE>

possession of, and it shall be lawful for the Trustee, by such officer or agent
as it may appoint, to take possession of all or any part of the Project,
including the rights and the position of the Issuer under the Lease Agreement,
and the Trustee shall be authorized to hold, operate and manage the same, and,
from time to time, make all needful repairs and improvements as it shall deem
wise; and the Trustee, subject to the Lease Agreement may, in accordance with
the instruction of the Collateral Agent, lease the Project or any part thereof
in the name and for the account of the Issuer and collect, receive and sequester
the rents, revenues, earnings, income, products and profits therefrom, and out
of the same and of any moneys received from any receiver of the same, pay
expenses of so taking, holding and managing the same, including reasonable
compensation to the Trustee, its agent and counsel, and any charges of the
Trustee hereunder, and any taxes and assessments and other charges prior to the
lien and security interests of this Indenture and the Security Deed which the
Trustee may deem it wise to pay, and all expenses of such repairs and
improvements, and apply the remainder of the moneys to received in accordance
with the provisions of Section 11.09. Whenever all that is due and payable with
respect to the Bonds shall have been paid in full or all defaults under this
Indenture made good, the Trustee shall surrender possession to the Issuer, its
successors or assigns, but the Trustee shall have the same right of entry upon
any subsequent event of default hereunder.

         While in possession of such property, the Trustee shall render annually
to the Issuer and the Lessee and also to the owners of the Bonds at their
addresses as shown by the registration books kept by the Trustee a summarized
statement of income and expenditures in connection therewith.

     SECTION 11.04. OTHER REMEDIES. Upon the occurrence and continuance of an
event of default the Trustee shall have the power to proceed, in accordance with
the instructions of the Collateral Agent, with any right or remedy granted by
the Constitution and laws of the State of Georgia, as it may deem best,
including any suit, action or special proceeding in equity or at law for the
specific performance of any covenant or agreement contained herein or for the
enforcement of any proper, legal or equitable remedy as the Trustee shall deem
most effectual to protect the rights aforesaid, insofar as such may be
authorized by law, and the right to the appointment, as a matter of right and
without regard to the sufficiency of the security afforded by the Trust Estate,
of a receiver for all or any part of the Trust Estate and the rents, revenues
and receipts thereof; the rights herein specified are to be cumulative to all
other available rights, remedies or powers and shall not exclude any such
rights, remedies or powers. Without intending to limit the foregoing rights,
remedies and powers by virtue of such specification, the Trustee is authorized
to exercise any and all rights available from time to time under the U.C.C.
including the right to further assign the Issuer's right, title and interest in
the Lease Agreement to a successor trustee in the manner set forth in this
Indenture.

     SECTION 11.05. RIGHTS OF BONDHOLDERS. Upon the occurrence and continuance
of an event of default and if requested so to do by the owners of a majority in
principal amount of Bonds outstanding and provision of indemnity to the Trustee

such one or more of the rights and remedies conferred by this Article as such
owners of the Bonds shall have instructed the Trustee, subject, however to the
provisions of Section 12.15.

                                      A-29

<PAGE>

         No right or remedy by the terms of this Indenture conferred upon or
reserved to the Trustee (or to the owners of the Bonds) is intended to be
exclusive of any other right or remedy, but each and every such right and remedy
shall be cumulative and shall be in addition to any other right or remedy given
to the Trustee or to the owners of the Bonds or now or hereafter existing at
law, in equity or by statute.

         No delay or omission to exercise any right or remedy accruing upon any
event of default shall impair any such right or remedy or shall be construed to
be a waiver of any such event of default or acquiescence therein; and every such
right and remedy may be exercised from time to time and as often as may be
deemed expedient.

         No waiver of any event of default hereunder, whether by the Trustee or
by the owners of the Bonds, shall extend to or shall affect any subsequent event
of default or shall impair any rights or remedies consequent thereon.

     SECTION 11.06. RIGHT OF OWNERS OF THE BONDS TO DIRECT PROCEEDINGS. Anything
in this Indenture to the contrary notwithstanding, upon the occurrence and
continuance of an event of default, the owners of a majority in principal amount
of Bonds outstanding shall have the right, at any time, by an instrument or
instruments in writing executed and delivered to the Trustee, to direct the
method and place of conducting all proceedings to be taken in connection with
the enforcement of the terms and conditions of this Indenture, or for the
appointment of a receiver or any other proceedings hereunder; provided, that
such direction shall not be otherwise than in accordance with the provisions of
law and of this Indenture.

     SECTION 11.07. APPOINTMENT OF RECEIVERS. Upon the occurrence of an event of
default and upon the filing of a suit or other commencement of judicial
proceedings to enforce the rights and remedies of the Trustee and of the owners
of the Bonds under this Indenture, the Trustee shall, with the consent of the
Collateral Agent, be entitled, as a matter of right, to the appointment of a
receiver or receivers of the Project and of the rents, revenues and receipts
thereof and therefrom, pending such proceedings, with such powers as the court
making such appointment shall confer.

     SECTION 11.08. WAIVER OF BENEFIT OF LAWS. Upon the occurrence of an event
of default, to the extent that such rights may then lawfully be waived, neither
the Issuer, nor anyone claiming through or under it, shall set up, claim or seek
to take advantage of any appraisement, valuation, stay, extension or redemption
laws now or hereafter in force, in order to prevent or hinder the enforcement of
the Security Deed or the foreclosure of the Security Deed, but the Issuer, for
itself and all who may claim through or under it, hereby waives, to the extent
that they lawfully may do so, the benefit of all such laws and all right of
appraisement and redemption to which it may be entitled under the laws of the
State.

SECTION 11.09. APPLICATION OF MONEYS. All moneys received by the Trustee
pursuant to any right given or action taken under the provisions of this Article
shall be transferred to the Collateral Agent and disbursed in accordance with
the Collateral Agency Agreement.

         Whenever all Bonds and interest thereon have been paid under the
provisions of this Section 11.09 and all expenses and charges of the Trustee
have been paid, any balance remaining in the Bond Fund shall, subject to the
Lease Agreement, be paid to the Lessee as provided in Section 6.09 hereof.

     SECTION 11.10. RIGHTS AND REMEDIES VESTED IN TRUSTEE. Subject to the
provisions of Section 11.05, all rights and remedies of action (including the
right to file proof of claims) under this Indenture or under any of the Bonds
may be enforced by the Trustee without the possession of any of the Bonds or the
production thereof in any trial or other proceedings relating thereto and any
such suit or proceeding instituted by the Trustee shall be brought in its name
as Trustee without the necessity of joining as plaintiffs or defendants any
owners of the Bonds, and any recovery of judgment shall be for the equal benefit
of the owners of the Bonds.

     SECTION 11.11. RIGHTS AND REMEDIES OF OWNERS OF THE BONDS. No owner of any
Bonds shall have any right to institute any suit, action or proceeding in equity
or at law for the enforcement of this Indenture, for the execution of any trust
thereof or for the appointment of a receiver or to enforce any other right or
remedy hereunder, unless a default has occurred of which the Trustee has been
notified as provided in subsection (h) of Section 12.01 hereof, or of which by
said subsection it is deemed to have notice, and in either case unless (i) such
default shall have become an event of default and the owners of 100% in
principal amount of Bonds outstanding shall have made written request to the
Trustee and shall have offered reasonable opportunity either to proceed to
exercise the powers hereinbefore granted or to institute such action, suit or
proceeding in its own name, such owners have offered to the Trustee indemnity as
provided in Section 12.01(m) hereof, (ii) the written consent of the Collateral
Agent shall have been obtained, and (iii) the Trustee shall thereafter fail or
refuse to exercise the powers hereinbefore granted, or to institute such action,
suit or proceeding in its, his or their own name or names. Such notification,
request and offer of indemnity are hereby declared in every case at the option
of the Trustee to be conditions precedent to the execution of the powers and
trusts of this Indenture and to any action or cause of action for the
enforcement of this Indenture, or for the appointment of a receiver or for any
other right or remedy hereunder; it being understood and intended that no one or
more owners of the Bonds shall have any right in any manner whatsoever to
affect, disturb or prejudice the lien of this Indenture by its, his or their
action or to enforce any right or remedy hereunder except in the manner herein
provided, and that all proceedings at law or in equity shall be instituted, had
and maintained in the manner herein provided and for the equal benefit of the
owners of all Bonds. Nothing in this Indenture contained shall, however, affect
or impair the right of any owner of the Bonds to enforce the payment of the
principal of and interest on any Bond at and after the maturity thereof, or the
obligation of the Issuer to pay the principal of and interest on each of the
Bonds issued hereunder to the respective owners hereof at the time, place, from
the source and in the manner expressed in the Bonds.

     SECTION 11.12. TERMINATION OF PROCEEDINGS. In case the Trustee shall have
proceeded to enforce any right or remedy under this Indenture by the appointment
of a receiver, by entry or otherwise, and such proceedings shall have been
discontinued or abandoned for any reason, or shall have been determined
adversely, then and in every such case the Issuer and the Trustee shall be
restored to their former positions and rights hereunder with respect to the
Trust Estate, and all rights, remedies and powers of the Trustee shall continue
as if no such proceedings had been taken.

     SECTION 11.13. WAIVERS OF EVENTS OF DEFAULT. The Trustee, with the consent
of the Collateral Agent, (a) may waive any event of default hereunder and its
consequences and rescind any declaration of maturity of principal and its
consequences, if such event of default has been cured and there is no longer
continuing any default hereunder, and (b) shall waive any event of default
hereunder and its consequences and rescind any declaration of maturity of
principal, upon the written request of the owners of a majority in principal
amount of the Bonds outstanding; provided, however, that there shall not be
waived (i) any event of default pertaining to the payment of the principal of
any Bond at its maturity date or any prepayment date prior to maturity, or (ii)
any event of default pertaining to the payment when due of the interest on any
Bond, unless prior to such waiver or rescission, all arrears of principal (due
otherwise than by declaration) and interest, with interest (to the extent
permitted by law) at the rate borne by the Bonds on overdue installments of
principal and interest and all arrears of payments of principal when due, as the
case may be, and all expenses of the Trustee due hereunder in connection with
such event of default, shall have been paid or provided for, and in case of any
such waiver or rescission, then the Issuer, the Trustee and the owners of the
Bonds shall be restored to their former positions and rights hereunder
respectively, but no such waiver or rescission shall extend to any subsequent or
other event of default, or impair any right consequent thereon.

                                   THE TRUSTEE

     SECTION 12.01. ACCEPTANCE OF THE TRUSTS. The Trustee hereby accepts the
trusts imposed upon it by this Indenture, and agrees to perform such duties and
only such duties as are specifically set forth in this Indenture upon and
subject to the following express terms and conditions:

          (a)    The Trustee, prior to the occurrence of an event of default and
       after the curing of all events of default which may have occurred,
       undertakes to perform such duties and only such duties as are
       specifically set forth in this Indenture, and no implied covenants or
       obligations shall be read into this Indenture against the Trustee. In
       case an event of default has occurred and is continuing, the Trustee
       shall exercise such of the rights and powers vested in it by this
       Indenture, and use the same degree of care and skill in their
       exercise, as a prudent man would exercise or use under the
       circumstances in the conduct of his own affairs.

          (b)    The Trustee may consult with counsel selected by it and the
       advice or opinion of such 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 reliance thereon.

          (c)   The Trustee may execute any of the trusts or powers hereunder or
       perform any duties hereunder either directly or by agents or attorneys
       and the Trustee shall not be responsible for any misconduct or
       negligence on the part of any agent or attorney appointed in good
       faith by it hereunder.

          (d) The Trustee shall not be responsible for any recital herein, or in
       the Bonds

                                      A-32

<PAGE>

       (except in respect to the authentication certificate of the Trustee
       endorsed on the Bonds), or for the recording or rerecording, filing or
       re-filing of this Indenture, the Lease Agreement or the Security Deed,
       or for insuring the Trust Estate or any part of the Project or
       collecting any insurance moneys, or for the validity of the execution
       by the Issuer of this Indenture or of any supplements hereto or
       instruments of further assurance, or for the sufficiency of the
       security for the Bonds, or for the value of or title in and to the
       Trust Estate or any part of the Project or otherwise as to the
       maintenance of the security hereof; provided that, as set forth in
       Section 8.8 of the Lease, the Trustee shall provide its reasonable
       cooperation to the Issuer and the Lessee in the filing of continuation
       statements relating to the liens and security interests created under
       the Security Deed and this Indenture; and provided further that if the
       Trustee enters into possession of a part or all of the Trust Estate
       pursuant to any provision of this Indenture it shall use due diligence
       in preserving the same, and the Trustee shall not be bound to
       ascertain or inquire as to the performance or observance of any
       covenants, agreements or conditions on the part of the Issuer or on
       the part of the Lessee under the Lease Agreement, except as
       hereinafter set forth; but the Trustee may require of the Issuer or
       the Lessee full information and advice as to the performance of the
       covenants, agreements and conditions aforesaid and as to the condition
       of the Trust Estate. The Trustee shall not be liable for any loss
       suffered in connection with any investment of funds made by it in
       accordance with Section 8.01 and 8.02 hereof.

          (e) The Trustee may become the owner of Bonds with the same rights
       which it would have if it were not Trustee.

          (f)   The Trustee shall be protected in acting upon any notice,
       request, consent, certificate, order, affidavit, letter, telegram or
       other paper or documents believed to be genuine and correct and to have
       been signed or sent by the proper Person or Persons. Any action taken by
       the Trustee, pursuant to this Indenture upon the request, authority or
       consent of any Person who at the time of making such request or giving
       such authority or consent is the owner of any Bond, shall be conclusive
       and binding upon all future owners of the same Bond and upon Bonds
       issued in exchange therefor or in place thereof.

          (g)   As to the existence or nonexistence of any fact or as to the
       sufficiency or validity of any instrument, paper or proceeding, the
       Trustee shall be entitled to rely upon a certificate signed on behalf
       of the Issuer by the Chairman or Vice Chairman of the Issuer and
       attested by the Secretary of the Issuer as sufficient evidence of the
       facts therein contained and prior to the occurrence of a default of
       which the Trustee has been notified as provided in subsection (h) of
       this Section, or of which by said subsection it is deemed to have
       notice, shall also be at liberty to accept a similar certificate to
       the effect that any particular dealing, transaction or action is
       necessary or expedient, but may at its discretion secure such further
       evidence deemed necessary or advisable, but shall in no case be bound
       to secure the same. The Trustee may accept a certificate of the
       Secretary of the Issuer under its seal to the effect that a resolution
       in the form therein set forth has been adopted by the Issuer as
       conclusive evidence that such resolution has been duly adopted, and is
       in full force and effect.

          (h)   The right of the Trustee to do things enumerated in this
       Indenture shall not

                                      A-33

<PAGE>

       be construed as a duty and the Trustee shall not be answerable for
       other than its gross negligence or willful default.

          (i)    The Trustee shall not be personally liable for any debts
       contracted or for damages to persons or property, or for salaries or
       nonfulfillment of contracts during any period in which it may be in
       the possession of or managing the Project as in this Indenture
       provided.

          (j)   At reasonable times the Trustee, and its duly authorized agents,
       attorneys, experts, engineers, accountants and representatives who are
       acceptable to the Lessee, and accompanied by an official of the
       Lessee, shall have the right to inspect the Project as well as all
       books, papers and records of the Issuer pertaining to the Project and
       the Bonds, and to take copies of such memoranda from and in regard
       thereto only as required from the books, papers and records of the
       Issuer.

          (k)   The Trustee shall not be required to give any bond or surety in
       respect of the execution of the said trusts and powers or otherwise in
       respect of the premises.

          (l)   Notwithstanding anything elsewhere in this Indenture contained,
       the Trustee shall have the right, but shall not be required, to
       demand, in respect of the authentication of any Bonds, the withdrawal
       of any cash, the release of any property, or any action whatsoever
       within the purview of this Indenture, any showings, certificates,
       opinions of Counsel, appraisals or other information, or corporate
       action or evidence thereof, in addition to that by the terms hereof
       required as a condition of such action by the Trustee relevant to and
       deemed desirable in connection with the authentication of any Bonds,
       the withdrawal of any cash, or the taking of any other action by the
       Trustee.

          (m)   Before taking any action hereunder the Trustee may require that
       a satisfactory indemnity bond be furnished for the reimbursement of
       all expenses to which it may be put and to protect it against all
       liability, except liability which is adjudicated to have resulted from
       the gross negligence or willful misconduct of the Trustee by reason of
       any action so taken. None of the provisions contained in this
       Indenture shall require the Trustee to expend or risk its own funds or
       otherwise to incur financial liability in the performance of any of
       its duties or the exercise of any of its rights or powers hereunder.

          (n)   All moneys received by the Trustee or any paying agent for the
       Bonds shall, until used or applied or invested 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 herein or
       by law. Neither the Trustee nor any such paying agent shall be under any
       liability for interest on any moneys received hereunder except such as
       may be agreed upon.

     SECTION 12.02. FEES, CHARGES AND EXPENSES OF TRUSTEE. The Trustee shall be
entitled to payment and/or reimbursement for reasonable fees for its services
rendered hereunder and all advances, reasonable Counsel fees and expenses and
other expenses reasonably and necessarily made or incurred by the Trustee in
connection with such services. Upon the occurrence of an event of default, but
only upon such occurrence, the Trustee shall have a first

                                      A-34
<PAGE>

lien on the Trust Estate with right of payment prior to payment of the principal
of and interest on any Bond for the foregoing advances, fees, costs and expenses
incurred.

     SECTION 12.03.    [INTENTIONALLY OMITTED].

     SECTION 12.04. INTERVENTION BY TRUSTEE. In any judicial proceeding to which
the Issuer is a party which, in the opinion of the Trustee and its Counsel, has
a substantial bearing on the interest of the owners of the Bonds, the Trustee
shall intervene on behalf of the owners of the Bonds if so requested in writing
by the owners of at least 100% in principal amount of the Bonds. The rights and
obligations of the Trustee under this Section are subject to the approval of a
court of competent jurisdiction.

     SECTION 12.05. SUCCESSOR TRUSTEE. Any corporation or association into which
the Trustee may be converted or merged, or with which it may be consolidated, or
to which it may sell or transfer its trust business and assets as a whole or
substantially as a whole, or any corporation or association resulting from any
such conversion, merger, consolidation, sale or transfer to which it is a party,
IPSO FACTO, shall be and become successor Trustee hereunder and vested with all
of the title to the Trust Estate and all the trusts, powers, discretions,
immunities, privileges and all other matters as was its predecessor, without the
execution or filing of any instrument or any further act, deed or conveyance on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

     SECTION 12.06. RESIGNATION BY THE TRUSTEE. The Trustee and any successor
Trustee may at any time resign from the trusts hereby created by giving 30 days'
written notice to the Issuer and the Lessee and by first class mail to each
registered owner of Bonds, and such resignation shall take effect at the end of
such 30 day period, or upon the earlier appointment of a successor Trustee by
the owners of the Bonds or by the Issuer. Such notice to the Issuer may be
served personally or sent by registered or certified mail.

     SECTION 12.07. REMOVAL OF THE TRUSTEE. The Trustee may be removed at any
time, by an instrument or concurrent instruments in writing delivered to the
Trustee and to the Issuer, and signed by the owners of a majority in principal
amount of the Bonds.

     SECTION 12.08. APPOINTMENT OF SUCCESSOR TRUSTEE BY THE OWNERS OF THE BONDS;
TEMPORARY TRUSTEE. If the Trustee hereunder shall resign, be removed, be
dissolved, be in course of dissolution or liquidation, or shall otherwise become
incapable of acting hereunder or in case it shall be taken under the control of
any public officer, officers or a receiver appointed by a court, a successor may
be appointed by the owners of a majority in principal amount of the Bonds, by an
instrument or concurrent instruments in writing signed by such owners, or by
their attorneys in fact, duly authorized; provided, nevertheless, that in case
of such vacancy the Issuer by an instrument signed by the Chairman of the Issuer
and attested by the Secretary of the Issuer under its seal, may appoint a
temporary Trustee to fill such vacancy until a successor Trustee shall be
appointed by the owners of the Bonds in the manner above provided; and any such
temporary Trustee shall immediately and without further act be superseded by the
Trustee so appointed by such owners of the Bonds. Every such Trustee appointed
pursuant to the provisions of this Section shall be a trust company or bank
(having trust powers) in good standing, within or outside the State of Georgia,
having an unimpaired capital and surplus of not

                                      A-35
<PAGE>

less than fifty million dollars ($50,000,000), if there be such an institution
willing, qualified and able to accept the trust upon reasonable or customary
terms.

     SECTION 12.09. CONCERNING ANY SUCCESSOR TRUSTEE. Every successor Trustee
appointed hereunder shall execute, acknowledge and deliver to its predecessor
and also to the Issuer an instrument in writing accepting such appointment
hereunder, and thereupon such successor, without any further act, deed or
conveyance, shall become fully vested with all the estates, properties, rights,
powers, trusts, duties and obligations of its predecessor; but such predecessor
shall, nevertheless, on the written request of the Issuer, or of its successor,
execute and deliver an instrument transferring to such successor Trustee all the
estates, properties, rights, powers and trusts of such predecessor hereunder;
and every predecessor Trustee shall deliver all securities and moneys held by it
as Trustee hereunder to its successor. Should any instrument in writing from the
Issuer be required by any successor Trustee in order to more fully and certainly
vest in such successor the estates, properties, rights, powers and trusts hereby
vested or intended to be vested in the predecessor any and all such instruments
in writing shall, on request, be executed, acknowledged and delivered by the
Issuer. The resignation of any Trustee and the instrument or instruments
removing any Trustee and appointing a successor hereunder, together with all
other instruments provided for in this Article, shall be filed and/or recorded
by the successor Trustee in each recording office where the Indenture and Lease
Agreement shall have been filed and/or recorded.

     SECTION 12.10. RIGHT OF TRUSTEE TO PAY TAXES AND OTHER CHARGES. Subject to
the Lessee's rights to contest the following under the Lease, if any tax,
assessment or governmental or other charge upon any part of the Trust Estate or
the Project is not paid as required herein, the Trustee may pay such tax,
assessment or charge, without prejudice, however, to any rights of the Trustee
or the owners of the Bonds hereunder arising in consequence of such failure; and
any amount at any time so paid under this Section, with interest thereon from
the date of payment at the rate per annum borne by the Bonds, shall become so
much additional indebtedness secured by this Indenture, and the same shall be
given a preference in payment over the principal of and interest on the Bonds
and shall be paid out of the revenues and receipts from the Trust Estate, if not
otherwise caused to be paid; but the Trustee shall not be under obligation to
and shall not make any such payment unless it shall have been requested to do so
by the owners of a majority in principal amount of the Bonds and shall have been
provided with sufficient moneys for the purpose of making such payment.

     SECTION 12.11. TRUSTEE PROTECTED IN RELYING UPON RESOLUTIONS, ETC. The
resolutions, opinions, certificates and other instruments provided for in this
Indenture may be accepted by the Trustee as conclusive evidence of the facts and
conclusions stated therein and shall be full warrant, protection and authority
to the Trustee for the release of property and the withdrawal of moneys
hereunder.

     SECTION 12.12. SUCCESSOR TRUSTEE AS CUSTODIAN OF FUNDS, PAYING AGENT AND
BOND REGISTRAR. In the event of a change in the office of Trustee, the
predecessor Trustee which has resigned or has been removed shall cease to be the
owner of the Construction Fund and Bond Fund, paying agent for the principal of
and interest on the Bonds and Bond Registrar, and the successor Trustee shall
become such owner, paying agent and Bond Registrar.

     SECTION 12.13. TRUST ESTATE MAY BE VESTED IN CO-TRUSTEE. It is the purpose
of this Indenture that there shall be no violation of any law of any
jurisdiction (including particularly the laws of the State of Georgia) denying
or restricting the right of banking corporations or associations to transact
business as a trustee in such jurisdiction. It is recognized that in case of
litigation under this Indenture, and in particular in case of the enforcement of
either the Indenture or the Lease Agreement upon the occurrence of an event of
default, it may be necessary that there be appointed an additional individual or
institution as a separate Trustee or Co-Trustee. The following provisions of
this Section 12.13 are adapted to these ends.

         In the event of the incapacity or lack of authority of the Trustee, by
reason of any present or future law of any jurisdiction, to exercise any of the
rights, powers and trusts herein granted to the Trustee or to hold title to the
Trust Estate or to take any other action which may be necessary or desirable in
connection therewith, the Issuer with the consent of the Lessee may appoint, and
at the request of the Trustee shall appoint, a separate Trustee or Co-Trustee
and each and every remedy, power, right, claim, demand, cause of action,
immunity, estate, title, interest and lien expressed or intended by this
Indenture to be exercised by or vested in or conveyed to the Trustee with
respect thereto shall be exercisable by and vest in such separate Trustee or
Co-Trustee but only to the extent necessary to enable the separate Trustee or
Co-Trustee to exercise such rights, powers and trusts, and every covenant and
obligation necessary to the exercise thereof by such separate Trustee or
Co-Trustee shall run to and be enforceable by either of them.

         Should any deed, conveyance or instrument in writing from the Issuer be
required by the separate Trustee or Co-Trustee so appointed in order to more
fully and certainly vest in and confirm to him or it such properties, rights,
powers, trusts, duties and obligations, any and all such deeds, conveyances and
instruments shall, on request, be executed, acknowledged and delivered by the
Issuer. In case any separate Trustee or Co-Trustee or a successor to either,
shall die, become incapable of acting, resign or be removed, all the estates,
properties, rights, powers, trusts, duties and obligations of such separate
Trustee or Co-Trustee, so far as permitted by law, shall vest in and be
exercised by the Trustee until the appointment of a new Trustee or successor to
such separate Trustee or Co-Trustee.

     SECTION 12.14.    [INTENTIONALLY OMITTED].

     SECTION 12.15. THIS ARTICLE CONTROLS. Whether or not therein expressly so
provided every provision of this Indenture relating to the conduct or affecting
the liability of the Trustee shall be subject to the provisions of this Article
XII.

     SECTION 12.16. CONSEQUENTIAL DAMAGES. Anything in this Indenture to the
contrary notwithstanding, in no event shall the Trustee be liable under or in
connection with this Indenture for indirect, special, incidental or
consequential loss or damage of any kind whatsoever, including lost profits,
whether or not the likelihood of such loss or damage was known to the Trustee
and regardless of the form of action.

                             SUPPLEMENTAL INDENTURES

     SECTION 13.01. SUPPLEMENTAL INDENTURES NOT REQUIRING CONSENT OF OWNERS OF
THE BONDS. The Issuer and the Trustee may without the consent of, or notice to,
any of the owners of the Bonds, enter into an indenture or indentures
supplemental to this Indenture as shall not be inconsistent with the terms and
provisions hereof for any one or more of the following purposes:

          (a)      to cure any ambiguity or formal defect or omission in this
     Indenture;

          (b)      to grant to or confer upon the Trustee for the benefit of the
     owners of the Bonds any additional rights, remedies, powers or authorities
     that may lawfully be granted to or conferred upon the owners of the Bonds
     or the Trustee or either of them;

          (c) to subject to the lien and pledge of this Indenture additional
     rents, revenues or receipts, properties or collateral;

          (d)      in connection with the issuance of Additional Bonds;

          (e)      to modify, amend or supplement this Indenture or any
     indenture supplemental hereto in such manner as to permit the qualification
     hereof and thereof under the Trust Indenture Act of 1939, as amended, or
     any similar federal statute hereafter in effect or to permit the
     qualification of the Bonds for sale under the securities laws of any of the
     states of the United States of America, and, if they so determine, to add
     hereto or to any indenture supplemental hereto such other terms, conditions
     and provisions as may be permitted by said Trust Indenture Act of 1939 or
     similar Federal statute;

          (f) to evidence the appointment of a separate Trustee or Co-Trustee or
     the succession of a new Trustee hereunder; or

          (g)      in connection with any other changes in this Indenture which
     are not to the prejudice of the interests of any registered owner of the
     Bonds, or in the judgment of the Trustee, are not to the prejudice of the
     interests of the Trustee.

     SECTION 13.02. SUPPLEMENTAL INDENTURES REQUIRING CONSENT OF OWNERS OF THE
BONDS. Exclusive of supplemental indentures covered by Section 13.01 hereof and
subject to the terms and provisions contained in this Section, and not
otherwise, the owners of not less than a majority in principal amount of the
Bonds outstanding shall have the right, from time to time, anything contained in
this Indenture to the contrary notwithstanding, to consent to and approve the
execution by the Issuer and the Trustee of such other indenture or indentures
supplemental hereto as shall be deemed necessary and desirable by the Issuer for
the purpose of modifying, altering, amending, adding to or rescinding, in any
particular, any of the terms or provisions contained in this Indenture or in any
supplemental indenture; provided, however, that nothing in this Section
contained shall permit, or be construed as permitting (a) an extension of the
maturity date (or mandatory sinking fund redemption) on which the principal of
or the interest on any

                                      A-38
<PAGE>

Bond is, or is to become, due and payable, (b) a reduction in the principal
amount of any Bond or the rate of interest thereon, (c) a privilege or priority
of any Bond or Bonds over any other Bond or Bonds, or (d) a reduction in the
principal amount of the Bonds required for consent to such supplemental
indenture.

         If the Issuer shall request the Trustee to enter into any such
supplemental indenture for any of the purposes of this Section, the Trustee
shall, upon being satisfactorily indemnified with respect to expenses, cause
notice of the proposed execution of such supplemental indenture to be given to
the owners of the Bonds. Such notice shall briefly set forth the nature of the
proposed supplemental indenture and shall state that copies thereof are on file
at the Principal Office of the Trustee for inspection by all owners of the
Bonds. If, within 60 days or such longer period as shall be prescribed by the
Issuer following the giving such notice, the owners of not less than a majority
in principal amount of the Bonds outstanding shall have consented to and
approved the execution of such supplemental indenture as herein provided, no
owner of any Bond shall have any right to object to any of the terms and
provisions contained therein, or the operation thereof, or in any manner to
question the propriety of the execution thereof, or to enjoin or restrain the
Trustee or the Issuer from executing the same or from taking any action pursuant
to the provisions thereof. Upon the execution of any such supplemental indenture
as in this Section permitted and provided, this Indenture shall be modified and
amended in accordance therewith.

         Anything herein to the contrary notwithstanding, a supplemental
indenture under this Article XIII which affects any right or obligation of the
Lessee under the Lease Agreement shall not become effective unless and until the
Lessee shall have consented to the execution and delivery of such supplemental
indenture. In this regard, the Trustee shall cause notice of the proposed
execution and delivery of any such supplemental indenture together with a copy
of the proposed supplemental indenture to be mailed by certified or registered
mail or overnight delivery to the Lessee at least 60 days prior to the proposed
date of execution and delivery of any such supplemental indenture. The Lessee
shall be deemed to have consented to the execution and delivery of any such
supplemental indenture if the Trustee does not receive a letter of protest or
objection thereto signed by or on behalf of the Lessee on or before 4:30 P.M.,
Eastern time, of the 60th day after the mailing of said notice and a copy of the
proposed supplemental indenture.

         The Trustee shall have no obligation to execute any supplemental
indenture which affects its own rights, duties, obligations or compensation.

     SECTION 13.03. TRUSTEE AUTHORIZED TO JOIN IN SUPPLEMENTS; RELIANCE ON
COUNSEL. The Trustee is authorized to join with the Issuer in the execution and
delivery of any supplemental indenture permitted by this Article XIII and, in so
doing, shall be fully protected by an opinion of Independent Counsel that such
supplemental indenture is so permitted and has been duly authorized by the
Issuer and that all things necessary to make it a valid and binding supplemental
indenture have been done.

REQUIRING CONSENT OF OWNERS OF THE BONDS. Except for the amendments, changes or
modifications as provided in Section 14.01 hereof, neither the Issuer nor the
Trustee shall consent to any other amendment, change or modification of the
Lease Agreement without the delivery of notice and the written approval or
consent of the owners of not less than a majority in principal amount of the
Bonds outstanding given and procured as in Section 13.02 provided. If at any

Security Deed, the Trustee shall, upon being satisfactorily indemnified with
respect to expenses, cause notice of such proposed amendment, change or

change or modification of the Lease Agreement or the Security Deed which affects
its own rights, duties, obligations or compensation. Such notice shall briefly
set forth the nature of such proposed amendment, change or modification and
shall state that copies of the instrument embodying the same are on file at the
Principal Office of the Trustee for inspection by owners of the Bonds.

     SECTION 14.03. TRUSTEE AUTHORIZED TO JOIN IN AMENDMENTS; RELIANCE ON
COUNSEL. The Trustee is authorized to join with the Issuer in the execution and
delivery of any amendment permitted by this Article XIV and, in so doing, shall
be fully protected by an opinion of Independent Counsel that such amendment is
so permitted and has been duly authorized by the Issuer and that all things
necessary to make it a valid and binding agreement have been done.

          such execution or by the certificate of any notary public or other
          officer authorized by law to take acknowledgments of deeds, certifying
          that the individual signing such instrument or writing acknowledged to
          him the execution thereof. Where such execution is by an officer of a
          corporation or a member of a partnership, on behalf of such
          corporation or partnership, such certificate or affidavit shall also
          constitute sufficient proof of his authority.

          (e) Any request, demand, authorization, direction, notice, consent,

powers hereunder, unless it shall first have been adequately indemnified to its
satisfaction against the cost, expenses and liability which may be incurred
thereby.

Issuer or any successor corporation, under or by reason of any of the
obligations, promises or agreements entered into between the Issuer and the
Lessee whether contained in the Lease Agreement or the Security Deed or to be
implied therefrom as being supplemental hereto or thereto, and that all personal
liability of the character against every such director, officer and employee is,
by the execution of the Lease Agreement, the Security Deed and this Indenture,

         This Bond is issued and the Indenture was authorized, executed and
delivered by the Issuer under and pursuant to the Constitution and laws of the
State of Georgia, including particularly, as amended, and the aforesaid
resolution of the Issuer. Pursuant to the terms of the Lease Agreement, the
Lessee must pay to the Issuer rental payments which are pledged to, and will be
fully sufficient to provide for, the payment of the principal of and the
interest on the Bonds as the same become due. In addition, the Issuer conveyed
that portion of the Project consisting of real property and granted a security
interest in that portion of the Project consisting of personal property and has
assigned all leases and rents therefrom to the Trustee pursuant to the terms of
a Deed to Secure Debt, Security Agreement and Assignment of Rents and Leases,
dated as of November 1, 1999. As additional security for the payment of the
Bonds, the Lessee will enter into a Guaranty Agreement with the Trustee, dated

unconditionally guarantee to the Trustee, for the benefit of the owners of the
Bonds, the payment of the principal of and interest on the Bonds as the same
become due.

         Pursuant to the Indenture, the Issuer may from time to time after the
issuance of all of the Bonds of this series which are to be issued have been
issued, sell and issue additional parity bonds for the purposes and subject to
the terms and conditions contained in the Indenture. Such additional parity
bonds will rank on a parity with and be equally secured with the Bonds of this
series. Reference is hereby made to Article IV of the Indenture for a more
complete description of the terms under which such additional parity bonds may
be issued by the Issuer.

         The Issuer has agreed that it will use its best efforts to keep the
Project continuously leased and will prescribe and collect rental payments
therefor sufficient to pay when due the principal of and the interest on the
Bonds. Reference to the Indenture is hereby made for a description of the
aforesaid Bond Fund which is charged with, and pledged to, the payment of the
principal of and the interest on the Bonds, the nature and extent of the
security, the rights, duties and obligations of the Issuer and the Trustee, the
rights of the owners of the Bonds, the terms and conditions under and upon the
occurrence of which the Indenture and the Lease Agreement may be modified, the
terms and conditions under which additional parity bonds may be issued and the
terms and conditions under and upon the occurrence of which the lien of the
Indenture may be defeased as to this Bond prior to the maturity or prepayment
date hereof, to all of the provisions of which the owner hereof, by the
acceptance of this Bond, assents.

         The Bonds of this series are subject to redemption prior to maturity at
any time in whole or in part, at a redemption price equal to the principal
amount to be redeemed plus accrued interest thereon to the date of redemption,
at the option of the Lessee, such option to be exercised by written notice
delivered to the Issuer and the Trustee at least 10 days prior to the date of
redemption.

         When Bonds are called for redemption as aforesaid, notice thereof
identifying the Bonds to be redeemed shall be given by mailing a copy of the
redemption notice by first class mail, postage prepaid, not less than 10 nor
more than 60 days prior to the redemption date to the registered owner of each
such Bond to be redeemed at the address shown on the Bond Register. Any notice
mailed as provided above shall be conclusively presumed to have been duly given,
whether or not the owner receives such notice. Failure to give any notice of
redemption, or any

                                      A-50
<PAGE>

defect therein, shall not affect the validity of any proceedings for the
redemption of any Bond as to which notice was given as provided in the
Indenture.

         Upon the giving of such notice, the Bonds or portions thereof so called
for redemption shall become and be due and payable at the applicable redemption
price and on the date specified for redemption in such notice. On the date
designated for redemption, notice having been given, moneys for payment of the
redemption price being on deposit with the Trustee or any paying agents and any
conditions to such redemption having been satisfied, the Bonds or portions
thereof shall cease to be entitled to any benefit or security under the
Indenture; and the registered owners thereof shall have no rights in respect of
such Bonds or such portions thereof so called for redemption except to receive
payment of the redemption price therefor and accrued interest thereon to the
redemption date from the moneys deposited with the Trustee or any paying agent
as provided in this paragraph.

         Less than the entire principal amount of any Bond in a denomination in
excess of $100,000 may be redeemed and in such case, upon the surrender of such
Bond, there shall be issued to the registered owner thereof, without charge
therefor, for the unredeemed balance of the principal amount of such Bond, at
the option of such registered owner, Bonds of the same stated maturity and
interest rate and in any of the authorized denominations, as more fully set
forth in the Indenture.

         This Bond is transferable by the registered owner hereof in person or
by his attorney duly authorized in writing at the principal office of the
Trustee, but only in the manner, subject to the conditions and limitations and
upon payment of the charges provided in the Indenture, and upon surrender and
cancellation of this Bond. Upon such transfer, a new fully registered Bond or
fully registered Bonds in the same aggregate principal amount and of any
authorized denomination or denominations shall be issued to the transferee or
transferees in exchange therefor.

         The owner of this Bond shall have the right to enforce the payment of
the principal hereof and the interest hereon at or after the maturity hereof,
and the owner of this Bond shall have the right to enforce the provisions of the
Indenture and to institute action to enforce the covenants therein, and to take
any action with respect to any Event of Default under the Indenture, and to
institute, appear in or defend any suit or other proceedings with respect
thereto, as provided in the Indenture. In certain events, on the conditions, in
the manner and with the effect set forth in the Indenture, the principal of all
the Bonds issued under the Indenture and then outstanding may become or may be
declared due and payable before the stated maturity thereof, together with the
interest accrued thereon. Modifications or alterations of the Indenture, or of
any supplements thereto, may be made only to the extent and in the circumstances
permitted by the Indenture.

         This Bond is issued with the intent that the laws of the State of
Georgia shall govern its construction.

         It is hereby certified and recited that all acts, conditions and things
required by the Constitution and laws of the State of Georgia to happen, exist
and be performed precedent to and in the issuance of this Bond, the execution of
the Indenture and the adoption of the aforesaid resolution by the Issuer, have

obligations of the Issuer, does not exceed or violate any constitutional or

authenticated by execution by the Trustee of the certificate hereon endorsed.

         When Bonds are called for redemption as aforesaid, notice thereof
identifying the Bonds to be redeemed shall be given by mailing a copy of the
redemption notice by first class mail, postage prepaid, not less than 10 nor
more than 60 days prior to the redemption date to the registered owner of each
such Bond to be redeemed at the address shown on the Bond Register. Any notice
mailed as provided above shall be conclusively presumed to have been duly given,
whether or not the owner receives such notice. Failure to give any notice of
redemption, or any

                                       4

defect therein, shall not affect the validity of any proceedings for the
redemption of any Bond as to which notice was given as provided in the
Indenture.

         Upon the giving of such notice, the Bonds or portions thereof so called
for redemption shall become and be due and payable at the applicable redemption
price and on the date specified for redemption in such notice. On the date
designated for redemption, notice having been given, moneys for payment of the
redemption price being on deposit with the Trustee or any paying agents and any
conditions to such redemption having been satisfied, the Bonds or portions
thereof shall cease to be entitled to any benefit or security under the
Indenture; and the registered owners thereof shall have no rights in respect of
such Bonds or such portions thereof so called for redemption except to receive
payment of the redemption price therefor and accrued interest thereon to the
redemption date from the moneys deposited with the Trustee or any paying agent
as provided in this paragraph.

         Less than the entire principal amount of any Bond in a denomination in
excess of $100,000 may be redeemed and in such case, upon the surrender of such
Bond, there shall be issued to the registered owner thereof, without charge
therefor, for the unredeemed balance of the principal amount of such Bond, at
the option of such registered owner, Bonds of the same stated maturity and
interest rate and in any of the authorized denominations, as more fully set
forth in the Indenture.

         This Bond is transferable by the registered owner hereof in person or
by his attorney duly authorized in writing at the principal office of the
Trustee, but only in the manner, subject to the conditions and limitations and
upon payment of the charges provided in the Indenture, and upon surrender and
cancellation of this Bond. Upon such transfer, a new fully registered Bond or
fully registered Bonds in the same aggregate principal amount and of any
authorized denomination or denominations shall be issued to the transferee or
transferees in exchange therefor.

         The owner of this Bond shall have the right to enforce the payment of
the principal hereof and the interest hereon at or after the maturity hereof,
and the owner of this Bond shall have the right to enforce the provisions of the
Indenture and to institute action to enforce the covenants therein, and to take
any action with respect to any Event of Default under the Indenture, and to
institute, appear in or defend any suit or other proceedings with respect
thereto, as provided in the Indenture. In certain events, on the conditions, in
the manner and with the effect set forth in the Indenture, the principal of all
the Bonds issued under the Indenture and then outstanding may become or may be
declared due and payable before the stated maturity thereof, together with the
interest accrued thereon. Modifications or alterations of the Indenture, or of
any supplements thereto, may be made only to the extent and in the circumstances
permitted by the Indenture.

         This Bond is issued with the intent that the laws of the State of
Georgia shall govern its construction.

         It is hereby certified and recited that all acts, conditions and things
required by the Constitution and laws of the State of Georgia to happen, exist
and be performed precedent to and in the issuance of this Bond, the execution of
the Indenture and the adoption of the aforesaid resolution by the Issuer, have
happened, exist and have been performed. The issuance of this

                                       5
<PAGE>

Bond and the series of which it forms a part, together with all other
obligations of the Issuer, does not exceed or violate any constitutional or
statutory limitation.

         This Bond shall not be entitled to any benefit under the Indenture nor
shall it become valid or obligatory for any purpose until it shall have been
authenticated by execution by the Trustee of the certificate hereon endorsed.
