(b) The Bonds shall bear interest (i) from their date of issuance,
if authenticated prior to the first Interest Payment Date, or (ii) otherwise
from the Interest Payment Date that is, or that immediately precedes, the date
on which such Bond is authenticated (unless payment of interest is in default,
in which case such Bond shall bear interest from the date to which interest has
been paid). Interest payable on the Bonds shall be calculated on the basis of a
360-day year of twelve 30-day months.

(c) Principal of, premium, if any, and interest on the Bonds shall

revenues and receipts derived from payments made under the Series A Note or the
Series B Notes, as applicable or otherwise pledged to the payment thereof as

the Bonds, whether by check or by wire transfer.

(d) If any principal of or interest on any Bond is not paid when
due (whether at maturity, by acceleration or call for redemption or otherwise),
then the overdue installments of principal and, to the extent permitted by law,
interest shall bear interest until paid at the same rate as set forth in such
Bond.

Section 203. Execution of Bonds. The Bonds shall be signed by the
manual or facsimile signature of the Chairman or the Vice Chairman of the
Authority, and the corporate seal of the Authority or a facsimile thereof shall
be affixed, imprinted, lithographed or reproduced thereon and shall be attested
by the manual or facsimile signature of the Secretary or the Assistant Secretary
of the Authority. In case any officer whose signature or a facsimile of whose
signature shall appear on any Bond shall cease to be such officer before the
delivery of the Bonds, such signature or such facsimile shall nevertheless be
valid and sufficient for all purposes the same as if he had remained in office
until such delivery. Any Bond may bear the facsimile signature of, or may be
signed by, such persons as at the actual time of the execution thereof shall be
the proper officers to sign such Bond, although at the date of delivery of such
Bond such persons may not have been such officers.

Section 204. Authentication of Bonds. The Bonds shall bear a
certificate of authentication, substantially in the form set forth in Exhibit A
with respect to the Series A Bonds, or in Exhibit B with respect to the Series B
Bonds, in either case duly executed by the Trustee. The Trustee shall
authenticate each Bond with the signature of an authorized representative of the
Trustee, but it shall not be necessary for the same representative to
authenticate all of the Bonds. Only such authenticated Bonds shall be entitled
to any right or benefit under this Indenture. Such certificate on any Bond
issued hereunder shall be conclusive evidence that the Bond has been duly issued
and is secured by the provisions hereof. No Bond shall be valid or obligatory
for any purpose or entitled to any right or benefit hereunder unless there shall
be endorsed on such Bond a certificate of authentication, as described herein,
duly executed by the Trustee, and such certificate of the Trustee upon any Bond
executed on behalf of the Authority shall be conclusive evidence and the only
evidence required that the Bond so authenticated has been duly issued hereunder
and that the Holder thereof is entitled to the benefits of this Indenture.

Section 205. Form of Bonds. The Series A Bonds shall be substantially
in the form set forth in Exhibit A and the Series B Bonds shall be substantially
in the form set forth in Exhibit B, each with such appropriate variations,
omissions and insertions as permitted or required by this Indenture. The Bonds
shall be numbered in the manner determined by the Trustee. Before authenticating
and delivering any Bond, the Trustee, as Registrar, shall complete the form of
such Bond to show the registered owner, principal amount, interest rate,
maturity date, number and authentication date of such Bond. The Bonds may have
printed on the reverse side thereof the opinion of Bond Counsel for such Bonds.

Section 206. Delivery of Bonds; Use of Bond Proceeds. The Trustee shall
authenticate and deliver the Bonds when there have been filed with it the
following:

(a) A certified copy of a resolution or resolutions of the
Authority authorizing (1) the execution and delivery of the Loan Agreement and
the assignment of the Notes, (2) the execution and delivery of this Indenture
and (3) the issuance, sale, execution and delivery of the Bonds.

(b) An original executed counterpart of this Indenture.

(c) Original executed counterpart of the Loan Agreement and the
Security Documents.

(d) The original executed Notes assigned by the Authority to the
Trustee.

(e) An Opinion of Counsel stating that the Financing Documents to
which the Borrower is a party have been duly authorized, executed and delivered
by the Borrower and are enforceable against the Borrower in accordance with
their terms, subject to customary bankruptcy and equitable principles
exceptions.

(f) An Opinion of Bond Counsel stating that the issuance of the
Bonds has been duly authorized and that under existing law interest on the Bonds
is not includable in gross income for federal income tax purposes.

(g) A request and authorization of the Authority, signed by its
Chairman or Vice Chairman, to the Trustee to authenticate and deliver the Bonds
to such person or persons named therein upon payment to the Trustee for the
account of the Authority of a specified sum.

From the proceeds of the Bonds, the Trustee shall (l) deposit in the
Reserve Fund the amount of the Reserve Fund Requirement, (2) deposit $80,000 of
proceeds of the Bonds ($73,400 from the Series A Bond proceeds and $6,600 from
the Series B Bond proceeds) into the Costs of Issuance Fund, (3) deposit in the
Project Fund the remaining amount of the proceeds of the Bonds.

Section 207. Registration of Transfer and Exchange of Bonds; Persons
Treated as Owners. The Bonds shall be negotiable instruments for all purposes
and shall be transferable by delivery, subject only to the provisions for
registration and registration of transfer endorsed on the Bonds. The Trustee
shall act as a bond registrar and in such capacity shall maintain registration
books for the registration of Bonds. The transfer of any Bond may be registered
only on the books kept for registration of transfer of the Bonds upon surrender
thereof to the Trustee, together with an assignment duly executed by the
Bondholder in person or by his duly authorized attorney or legal representative
in such form as shall be satisfactory to the Trustee. Upon any such transfer,
the Authority shall execute and the Trustee shall authenticate and deliver in
exchange for such Bond a new Bond or Bonds registered in the name of the
transferee, of the same maturity, bearing interest at the same rate and of any
denomination or denominations authorized by this Indenture.

Upon surrender of any Bonds at the principal corporate trust office of
the Trustee, together with an assignment duly executed by the Bondholder or his
duly authorized attorney or legal representative in such form as shall be
satisfactory to the Trustee, such Bonds may, at the option of the Holders
thereof, be exchanged for an equal aggregate principal amount of Bonds of the
same Series, maturity, of authorized denominations and bearing interest at the
same rate and in the same form as the Bonds surrendered for exchange, registered
in the name or names requested by the then Holder of such Bonds. The Authority
shall execute and the Trustee shall authenticate any Bonds whose execution and
authentication is necessary to provide for exchange of Bonds pursuant to this
Section 207.

Prior to due presentment for registration of transfer of any Bond,
the Trustee shall treat the registered owner as the person exclusively
entitled to payment of principal, premium, if any, and interest and the
exercise of all other rights and powers of the Bondholder, except that
interest payments shall be made to the persons registered as Bondholders on
the registration books of the Trustee as of the close of business on the
fifteenth day of the month next preceding the Interest Payment Date.

Section 208. Charges for Exchange and Registration of Transfer. Any
fees or costs incurred by the Authority, the Trustee or their respective
agents in the exchange or registration of transfer of Bonds shall be at the
expense of the Borrower, except that the Trustee shall make a charge to any
Bondholder requesting such exchange or registration in the amount of any tax
or other governmental charge required to be paid with respect thereto.

Section 209. Temporary Bonds. Prior to the preparation of Bonds in
definitive form, the Authority may issue temporary Bonds in registered form and
in such denominations as the Authority may determine but otherwise in
substantially the form set forth in Exhibit A or Exhibit B, as applicable, with
appropriate variations, omissions and insertions. Upon presentation and
surrender of Bonds in temporary form, the Trustee shall authenticate and deliver
in exchange therefor Bonds in definitive form of the same Series, maturity, and
interest rate and for the same aggregate principal amount. Until exchanged for
Bonds in definitive form, Bonds temporary form shall be entitled to the lien and
benefit of this Indenture.

Section 210. Mutilated, Lost, Stolen or Destroyed Bonds. If any Bond
has been mutilated, lost, stolen or destroyed, the Authority shall execute, and
the Trustee shall authenticate and deliver to the Holder thereof, a new Bond of
like series, with like interest rate, maturity and redemption provisions in
exchange and substitution for, and upon cancellation of, such mutilated Bond or
in lieu of and in substitution for such lost, stolen or destroyed Bond but only
if the Holder has paid the reasonable expenses and charges of the Authority and
the Trustee in connection therewith and, in the case of a lost, stolen or
destroyed Bond, (a) has filed with the Authority, the Borrower and the Trustee
evidence satisfactory to them that such Bond was lost, stolen or destroyed and
(b) has furnished to the Authority, the Borrower and the Trustee indemnity
satisfactory to them. If any such Bond has matured or been called for
redemption, instead of issuing a new Bond the Trustee may pay the same without
surrender thereof, after receipt of the evidence, expenses and charges and
indemnity referred to above. Upon the issuance of any Bond upon such exchange or
substitution, the Authority may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses, including counsel fees, of the Authority or the Trustee.

Every Bond issued pursuant to the provisions of this Section in
exchange or substitution for any Bond that is mutilated, destroyed, lost or
stolen shall constitute an additional contractual obligation of the Authority,
whether or not the destroyed, lost or stolen Bonds shall be found at any time,
or be enforceable by anyone, and shall be entitled to all the benefits hereof
equally and proportionately with any and all other bonds duly issued under this
Indenture. All Bonds shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Bonds, and shall preclude any and all other
rights or remedies, notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

Section 211. Cancellation and Disposition of Bonds. All Bonds that have
been paid (whether at maturity, by acceleration, call for redemption or
otherwise) or delivered to the Trustee by the Authority or the Borrower for
cancellation shall not be reissued. Unless otherwise directed by the Borrower,
the Trustee shall cremate, shred or otherwise dispose of such Bonds. The Trustee
shall deliver to the Borrower a certificate of any such cremation, shredding or
other disposition.

Section 212. Book-Entry Provisions. The Bonds shall be initially issued
as certificated bonds and shall be registered in the names of the registered
owners thereof. In the event that the Bonds shall be held in book-entry only
form, the Depository Trust Company ("DTC"), New York, New York, will act as
securities depository for the Bonds (the "Securities Depository"). In such case,
one fully-registered Bond of each maturity will be registered in the name of
Cede & Co., as nominee for DTC. So long as Cede & Co. is the Holder of the
Bonds, as nominee of DTC, references herein to the Holders of the Bonds shall
mean Cede & Co. and shall not mean the beneficial owners of the Bonds. The
following discussion is included in this Indenture solely for the purpose of
defining the responsibilities and roles of DTC and the relationship between DTC
and the beneficial holders of the Bonds in the event that the Bonds are held in
book-entry only form at some future time.

The interest of each of the beneficial owners of the Bonds will be
recorded through the records of a DTC participant. Transfers of beneficial
ownership interests in the Bonds which are registered in the name of Cede & Co.
will be accompanied by book entries made by DTC and, in turn, by the DTC
participants and indirect participants who act on behalf of the beneficial
owners of the Bonds.

DTC may determine to discontinue providing its service with respect to
the Bonds at any time by giving written notice and all relevant information on
the beneficial owners of the Bonds to the Authority, the Borrower and the
Trustee and discharging its responsibilities with respect thereto under
applicable law. If there is no successor Securities Depository appointed by the
Authority, at the request and expense of the Borrower, the Trustee shall deliver
Bonds to the beneficial owners thereof. The Authority, at the direction of the
Borrower, may determine not to continue participation in the system of book
entry transfers through DTC (or a successor Securities Depository) at any time
by giving reasonable written notice to DTC (or a successor Securities
Depository) and the Trustee. In such event, the Trustee will deliver Bonds to
the beneficial owners thereof at the expense of the Borrower and as directed in
writing by the Borrower.

The Authority and the Trustee shall recognize DTC or its nominee, Cede
& Co., while the registered owner, as the Holder of the Bonds for all purposes,
including payments, notices and voting. Conveyance of payments, notices and
other communications by DTC to DTC participants and by DTC participants and
indirect participants to beneficial owners of the Bonds will be governed by
arrangements among DTC, DTC participants and indirect participants, subject to
any statutory and regulatory requirements as may be in effect from time to time
and shall not be the responsibility of the Authority, the Borrower or the
Trustee.

In the event that (a) the Authority determines that DTC is incapable of
discharging its responsibilities described herein and under the Authority's
Blanket Letter of Representations (the "Representation Letter") on file with
DTC, (b) the Representation Letter shall be terminated for any reason, or (c)
the Authority determines that it is in the best interests of the beneficial
owners of the Bonds that they be able to obtain certificated Bonds, the
Authority shall notify the DTC of the availability of Bond certificates, and the
Bonds shall no longer be restricted to being registered in the bond register in
the name of Cede & Co., as nominee of DTC. The Authority is under no obligation
to make the determinations set forth in (a) and (c) above or to make any
investigation which would result in any such determination. The Authority may
determine that the Bonds shall be registered in the name of and deposited with a
successor depository operating a book-entry system, as may be acceptable to the
Authority, or such depository's agent or designee, and if the Authority does not
select such alternate book entry system, then the Bonds may be registered in
whatever name or names registered owners of Bonds transferring or exchanging
Bonds shall designate, in accordance with the provisions hereof. Notwithstanding
any other provision of this Indenture to the contrary, so long as any Bond is
registered in the name of Cede & Co., as nominee of DTC, all payments with
respect to principal of and interest on such Bond and all notices with respect
to such Bond shall be made and given, respectively, in the manner provided in
the Representation Letter.







ARTICLE III

Redemption of Bonds

Section 301. Redemption Dates and Prices. The Bonds may not be called for
redemption by the Authority except as provided below:

(a) Extraordinary Redemption. If the Borrower prepays the Notes,
or either of them, upon damage to, condemnation of or failure of title to the
Project or certain other extraordinary events as provided in the Loan Agreement,
the Series A Bonds and, if sufficient prepayment proceeds are available to fully
redeem the Series A Bonds, the Series B Bonds, are required to be redeemed in
whole on any day and, in the event of damage, condemnation or failure of title
to the extent provided in the Loan Agreement at the direction of the Borrower,
the Series A Bonds and, if sufficient prepayment proceeds are available to fully
redeem the Series A Bonds, the Series B Bonds, are subject to redemption in part
in integral multiples of $100,000 and increments of $5,000 in excess of $100,000
on any day at the direction of the Borrower, in either case upon payment of 100%
of the principal amount of the applicable series of Bonds to be redeemed plus
interest accrued to the redemption date.

(b) Optional Redemption. The Series B Bonds are subject to
optional redemption by the Authority, at the request of the Borrower in whole on
any date and in part on any Interest Payment Date at a redemption price equal to
the principal amount of such Series B Bonds to be redeemed plus accrued interest
thereon to the date of redemption. The Series A Bonds are not subject to
optional redemption prior to March 15, 2003. The Bonds are subject to optional
redemption by the Authority, at the request of the Borrower, on or after March
15, 2003, in whole on any date or in part on any Interest Payment Date, at a
redemption price equal to the principal amount to be redeemed plus accrued
interest thereon to the date set for redemption, together with a premium equal
to six percent (6%) of such principal amount if redeemed on or prior to March
15, 2005, three percent (3%) if redeemed after March 15, 2005 and on or prior to
March 15, 2006, two percent (2%) if redeemed after March 15, 2006 and on or

on or prior to March 15, 2008, and without premium if redeemed after March 15,
2008.

(c) Term Bond Mandatory Sinking Fund Redemption. The Series A
Bonds and the Series B Bonds are subject to mandatory sinking fund redemption
prior to maturity at a redemption price equal to the principal amount thereof,
plus accrued interest to the redemption date on March 15 of the following years
in the following amounts:

Sinking Fund
Year Installment

2023 330,000



On or before the 70th day next preceding any such mandatory sinking
fund redemption date, the Authorized Representative may:

(1) deliver to the Trustee for cancellation Bonds required to
be redeemed on such mandatory sinking fund redemption date in any
aggregate principal amount desired; or

(2) instruct the Trustee to apply a credit against the
Authority's mandatory sinking fund redemption obligation for any such
Bonds that previously have been redeemed (other than through the
operation of a mandatory sinking fund redemption) or purchased and
canceled or surrendered for cancellation by the Trustee and not
previously applied as a credit against any mandatory sinking fund
redemption obligation.

Each Bond so purchased, delivered or previously redeemed shall be
credited by the Trustee at 100% of the principal amount thereof against the
principal amount required to be redeemed on such mandatory sinking fund
redemption date. Any principal amount of Bonds so purchased, delivered or
previously redeemed in excess of the principal amount required to be redeemed on
such mandatory sinking fund redemption date shall similarly reduce the principal
amount of Bonds to be redeemed on the next mandatory sinking fund redemption
date. Upon receipt of the Bonds so purchased, delivered or previously redeemed
or instructions described in subparagraphs (1) and (2) above, the Trustee shall
hold any amounts in the appropriate sub-account of the Principal Account in
excess of the amount necessary to fulfill the remaining mandatory sinking fund
redemption requirement for the mandatory sinking fund redemption date, such
excess amount to be used to redeem Bonds of the appropriate series on the next
mandatory sinking fund redemption date or on the next date on which such Bonds
can be redeemed pursuant to Section 301(b), as directed by the Borrower's
Authorized Representative.

(d) Mandatory Redemption. The Bonds are subject to mandatory
redemption in whole on any day upon the occurrence of a Determination of
Taxability, at a redemption price equal to 100% of the principal amount thereof
plus interest, which shall accrue at the Tax-Exempt Rate until the Taxable Date,
and shall accrue at the Taxable Rate for the period beginning on the Taxable
Date and ending on the redemption date, provided, however, that Borrower shall
be credited any interest paid on the Bonds at the Tax-Exempt Rate during such
period. Such redemption will be made not more than 90 days after a Determination
of Taxability. In lieu of such redemption, the Borrower has the option of
changing the interest rate per year payable on the Bonds and the Notes to the
greater of (i) the interest rate then payable on the Bonds and the Notes, or
(ii) twelve percent (12%). If this option is chosen by the Borrower, the
Borrower shall notify the Authority and the Trustee within thirty (30) days of
the Determination of Taxability and the increase in the interest rate shall
become effective retroactive to the date of the Event of Taxability. The Bonds
are also subject to mandatory redemption upon abandonment of the Project by the
Borrower, for a period of ten (10) or more consecutive days, or upon the sale of
the Project by the Borrower. If any such sale or abandonment shall occur on or
before March 15, 2003, the Bonds shall be redeemed pursuant to this section at a
redemption price equal to 105% of the principal amount of the Bonds then
outstanding, plus accrued interest to the redemption date. If any such sale or
abandonment occurs after March 15, 2003, the Bonds shall be redeemed pursuant to
this section at the same redemption premiums set forth in Section 301(b) of this
Indenture, plus accrued interest to the redemption date. The Series B Bonds are
also subject to mandatory redemption at a redemption price equal to 100% of the
principal amount thereof plus accrued interest to the redemption date, with the
amount of the Reserve Fund if any, that is made available for such purpose in
accordance with Section 603 of this Indenture.

Section 302. Selection of Bonds to be Redeemed. If less than all of the
Bonds of any Series are to be redeemed pursuant to an extraordinary redemption
or optional redemption, the maturities of the Bonds of such Series to be
redeemed shall be selected by the Authorized Representative. If less than all of
the Bonds of any maturity of any series are to be redeemed, the Bonds to be
redeemed shall be selected by lot in such manner as the Trustee (or the
Securities Depository, if the Bonds are then being held in book-entry only form)
in its discretion may determine, each $5,000 portion of principal amount being
counted as one Bond for this purpose. If a portion of a Bond of any Series
having a principal amount of more than $5,000 shall be called for redemption, a
new Bond of such Series in principal amount equal to the unredeemed portion
thereof shall be issued to the Holder upon the surrender thereof.

Section 303. Notice of Redemption. The Trustee shall cause notice of
any redemption to be sent by registered or certified mail, with respect to the
Bonds to be redeemed not less than thirty (30) nor more than sixty (60) days
prior to the redemption date (i) to the Holder of each such Bond to be redeemed
at such Holder's address as it appears on the registration books maintained by
the Trustee and (ii) to each nationally recognized municipal securities
information repository. Failure to give such notice described in clause (i), or
any defect therein, shall not affect the validity of any proceedings for the
redemption of any such Bonds with respect to which no such failure has occurred.
Failure to give such notice described in clause (ii), or any defect therein,
shall not affect the validity of any proceedings for the redemption of any such
Bonds.

Each notice of redemption shall state at a minimum, the complete
official name of the issue, CUSIP number or numbers of the Bonds to be redeemed,
certificate numbers, amounts called of each certificate (for partial calls),
publication date, the date of issue, the interest rates and the maturity dates
of the Bonds being redeemed, the redemption date, the redemption price, the
place or places of redemption, including the Trustee's name and appropriate
address or addresses and the name of a contact person and telephone number.

the appropriate sub-account of the Interest Account the moneys to be transferred
thereto, including but not limited to, the moneys described in Sections 504,
602(a)(1), 602(b) and 602(c) of the Indenture, provided that all sums received
shall be first deposited in the Series A sub-account until the amount therein is
the amount required to be on deposit in such Series A sub-account at such date.
For so long as there is any short fall or deficiency in any Series A
sub-account, whether in the Principal Account or the Interest Account or in the
Series A Account of the Reserve Fund, no amount shall be deposited in any Series
B sub-account, and all amounts and receipts derived from the Notes, the Loan
Agreement or any security therefor shall be utilized to pay principal of,
interest, and premium, if any, on the Series A Bonds or to replenish the Series
A Account of the Reserve Fund. The Trustee shall pay interest on the Series A
Bonds and the Series B Bonds from the appropriate sub-account of the Interest
Account as the same becomes due. Investment earnings on amounts in the
sub-accounts of the Interest Account shall be credited thereto as earned.

The Trustee shall deposit into the appropriate sub-account of the
Principal Account the moneys to be transferred thereto, including but not
limited to, the moneys described in Sections 504, 602(a)(2), 602(b) and 602(c)
of the Indenture, provided that all sums received shall be first deposited in
the Series A sub-account until the amount therein is the amount required to be

The Borrower shall make payments on the Notes in amounts and at times
to allow the Trustee to make deposits to the appropriate Account and sub-account
of the Bond Fund in the following order, subject to credits as provided in this
Article VI:

(1) To the appropriate sub-account of the Interest Account
commencing on the Closing Date and continuing on April 15, 1998 and on
the 15th day of each month thereafter, an amount equal to one-sixth of
the amount of interest due on the Series A Bonds and the Series B Bonds
on the next following Interest Payment Date or such lesser amount that,
together with amounts already on deposit in the appropriate sub-account
of the Interest Account will be sufficient to pay interest on the
applicable Series of Bonds to become due on the next following Interest
Payment Date.

(2) To the appropriate sub-account of the Principal Account on
the 15th day of each month, beginning March 15, 2000, an amount equal
to one-twelfth of the amount of principal (including mandatory sinking
fund redemption requirements) that will become due on the Series A
Bonds and the Series B Bonds on the following March 15, or such lesser
amount that, together with amounts already on deposit in the
sub-accounts of the Principal Account will be sufficient to pay
principal of the applicable Series of the Bonds (including mandatory
sinking fund redemption requirements, in the case of the Term Bonds) to
become due on the following March 15.

(b) Furthermore, on the date that any Bonds are subject to
redemption pursuant to Sections 301 or are subject to payment as a result of any
acceleration under Section 902, the Borrower shall pay pursuant to the Notes for
deposit into the appropriate sub-accounts of each of the Principal Account and
the Interest Account, as applicable, the amount necessary to pay such Bonds upon
such redemption or acceleration.

(c) In the event that the balances in the Series A sub-accounts of
the Accounts in the Bond Fund are insufficient for the payment of the principal
of or interest on the Series A Bonds, when due, the Trustee shall transfer from
the Reserve Fund first to the Series A sub-account of the Interest Account and
then to the Series A sub-account of the Principal Account such amounts as may be
necessary to make such payment.

(d) If on any March 31, the excess balance in the Bond Fund (after
the withdrawals to be made therefrom on such date) ever exceeds one-twelfth
(1/12th) of the annual principal of, premium, if any, and interest that was due
on the Bonds from the next preceding March 15, such excess shall be applied by
the Trustee, at the direction of the Borrower, (a) to the purchase of the
applicable Series of Bonds at such price and upon such terms and conditions as
the Borrower may direct, or (b) in the event that such Bonds are then subject to
optional redemption, to the optional redemption of such Bonds on the first
optional redemption date occurring after such date at which such Bonds can be
redeemed, or (c) provided that the Trustee and the Borrower shall have received
an Opinion of Bond Counsel to the effect that such action will not affect the
tax-exempt status of the Bonds, to the payment of maturing principal or interest
on the applicable Series of Bonds when due. Unless there shall be delivered to
the Trustee and the Borrower an Opinion of Bond Counsel that such investments
will not affect the tax-exempt status of the Bonds, such excess moneys in the
sub-accounts of the Bond Fund shall not be invested at a "yield" in excess of
the "yield" on the applicable Series of Bonds, as described in Section 148 of
the Code.

(e) When the balance in any sub-account Bond Fund is sufficient to
redeem or pay at maturity all Bonds of a particular Series then Outstanding and
to pay all interest to accrue thereon prior to redemption or maturity, the
balance, if any, in the sub-accounts of the Bond Fund shall be held for
redemption or payment of the applicable Series of Bonds at the earliest
practicable date and the payment of interest thereon and for no other purpose.

Section 603. Reserve Fund. (a) On the date of issuance of the Bonds,
the Trustee shall deposit in the Reserve Fund for the benefit of the Holders of
the Bonds the amount of the Reserve Fund Requirement. Thereafter, the Borrower
shall ensure that the Reserve Fund is maintained at the levels required by this
Section. In the event that the Borrower shall certify to the Trustee that its
Debt Service Coverage Ratio, computed by the Borrower's independent certified
public accountants in accordance with the definition set forth in the Loan
Agreement, is 2.0 to 1.0 or greater, the Trustee shall withdraw the entire
amount then deposited in the Series B Account of the Reserve Fund, and shall
withdraw from the Series A Account of the Reserve Fund an amount that, when
combined with the amount withdrawn from the Series B Account of the Reserve
Fund, will be equal to the principal amount of the Series B Bonds then
Outstanding, plus interest accrued on the Series B Bonds to the date set for
redemption of such Series B Bonds in accordance with this Section 603, and shall
utilize such funds to redeem the Series B Bonds at 100% of the principal amount
thereof, plus accrued interest, in accordance with Section 301(d) of this
Indenture. In such event, the Reserve Fund Requirement shall be reduced to the
amount that remains in the Reserve Fund after giving effect to the withdrawal
and redemption contemplated by this Section and by Section 301(d) of this
Indenture.

(b) The Trustee shall use amounts in the Series A Account of the
Reserve Fund to make transfers, first to the Series A sub-account in the
Interest Account, then to the Series A sub-account in the Principal Account, of
the Bond Fund to the extent necessary to pay the principal of (whether at
maturity, by acceleration, call for redemption or otherwise) and interest on the
Series A Bonds as the same becomes due whenever moneys in such sub-accounts
(except for moneys held for the payment of Bonds that have been called for
redemption and not then presented for payment) are insufficient therefor. The
Trustee shall use amounts in the Series B Account of the Reserve Fund to make
transfers, first to the Series B sub-account in the Interest Account, then to
the Series B sub-account in the Principal Account, of the Bond Fund to the
extent necessary to pay the principal of (whether at maturity, by acceleration,
call for redemption or otherwise) and interest on the Series B Bonds as the same
becomes due whenever moneys in such sub-accounts (except for moneys held for the
payment of Bonds that have been called for redemption and not then presented for
payment) are insufficient therefor. In the event the balance in the Reserve Fund
falls below the Reserve Fund Requirement, the Borrower shall deposit funds to
the Reserve Fund to restore the balance therein to the Reserve Fund Requirement
from payments under the Loan Agreement and the Notes.

(c) In the event the balance in the Reserve Fund on any date of
valuation of the investments in the Reserve Fund required by Section 702 shall
exceed the Reserve Fund Requirement, the excess shall be credited to the Series
A sub-account of the Interest Account and used by the Trustee to pay interest on
the Series A Bonds, such that the amount deposited in the Reserve Fund equals
the Reserve Fund Requirement.

(d) The Investment Obligations in the Reserve Fund shall be valued
on each March 31, and on each date on which a withdrawal is made therefrom,
except withdrawals of excess moneys, as described in subsection (c) above. If
upon the valuation date, the balance of such Investment Obligations is less than
the Reserve Fund Requirement, the Trustee shall calculate the amount by which
the Reserve Fund Requirement exceeds such balance and shall immediately give the
Borrower notice of such deficiency and the amount necessary to cure the same. So
long as there has been no withdrawal from the Reserve Fund within the prior
twelve (12) months (other than withdrawals of excess moneys, as described in
subsection (c) above), upon the valuation of the Investment Obligations in the
Reserve Fund, the Borrower shall not be required to reimburse the Reserve Fund
for any loss resulting from a decline in the value of the Investment Obligations
unless the valuation of such Investment Obligations shows a valuation of less
than ninety percent (90%) of the Reserve Fund Requirement.

Section 604. Accounts within Funds. The Trustee may, and at the
direction of the Borrower shall, create accounts or sub-accounts within any fund
established by this Indenture and shall deposit amounts transferred to such fund
in accounts or sub-accounts therein as directed by an Authorized Representative.
In making transfers from any such fund, the Trustee shall draw on accounts
therein as directed by an Authorized Representative so long as required
transfers can be made consistent with such directions. Notwithstanding the name
of such accounts, all accounts shall be pledged equally and ratably to the
Series A Bonds, in the case of Series A sub-accounts and equally and ratably to
the Series B Bonds, in the case of the Series B Bonds sub-accounts, provided
that nothing herein shall be construed as granting or securing the Series B
Bonds on a parity basis with the Series A Bonds, the Series A Bonds being in all
respects superior in claim, right title and interest hereunder to the Project
and the collateral pledged by the Borrower in respect of this Indenture and the
Security Documents.

Section 605. Non-Presentment of Bonds. If any Bond is not presented for
payment when the principal thereof becomes due (whether at maturity, by
acceleration, call for redemption or otherwise), all liability of the Authority
to the Holder thereof for the payment of such Bond shall forthwith cease and be
completely discharged if funds sufficient to pay such Bond and interest due
thereon shall be held by the Trustee for the benefit of the Holder thereof, and
thereupon it shall be the duty of the Trustee to hold such funds, without
liability for interest thereon, for the benefit of the Holder of such Bond, who
shall thereafter be restricted exclusively to such funds for any claim of
whatever nature on his part on, or with respect to, such Bond or under this
Indenture. Moneys deposited with the Trustee which remain unclaimed five (5)
years after the date payment thereof becomes due shall be disposed of by the
Trustee in accordance with The Uniform Disposition of Unclaimed Property Act,
Chapter 11.1, Title 55, Code of Virginia of 1950, as amended. Thereafter, the
Trustee shall have no responsibility with respect to those moneys.

Section 606. Trustee's and Authority's Fees, Costs and Expenses. The
initial or acceptance fees and expenses of the Trustee and the Authority
relating to the Bonds shall be paid by the Borrower from its own funds or from
the Costs of Issuance Fund, as and when the same shall become due. All other
fees and expenses of the Trustee (including such reasonable fees and expenses
not incurred in the ordinary course of business), as provided in Section 1002,
and the fees and reasonable costs and expenses of the Authority directly related
to the financing of the Project, the issuance and delivery of the Bonds and the
performance of its duties and responsibilities pursuant to this Indenture, the
Loan Agreement, the Continuing Disclosure Agreement and other instruments and
documents required in connection therewith are to be paid by the Borrower from
payments made under the Loan Agreement. All such payments that are received by
the Trustee or the Authority shall not be deposited in the Bond Fund, the
Reserve Fund or other funds or accounts created hereunder, but may be expended
and used by the Authority or the Trustee for the purposes for which such
payments are received.

Section 607. Moneys To Be Held in Trust. All moneys required to be
deposited with or paid to the Trustee for the account of any of the funds
created by this Indenture shall be held by the Trustee in trust, and except for
moneys deposited with or paid to the Trustee for the redemption of Bonds, notice
of the redemption of which has been duly given, shall, while held by the
Trustee, constitute part of the trust estate and be subject to the lien hereof.

Section 608. Repayment to the Borrower from Funds. After payment in
full of the Bonds and the fees, charges and expenses of the Trustee, any other
paying agent and other amounts required to be paid hereunder, and the fees,
charges and expenses of the Authority and any other amounts required to be paid
by the Borrower under the Notes or the Loan Agreement, including amounts to be
paid pursuant to Section 4.6 of the Loan Agreement, all amounts remaining in any
of the funds created by this Indenture (except for unclaimed moneys as provided
in Section 606) shall be paid in accordance with the directions of the
Authorized Representative.

Section 609. Reports by Trustee. The Trustee shall make annual reports to
the Borrower of all moneys received and expended by the Trustee under this
Indenture.

invested and reinvested by the Trustee, as directed in writing or orally and
promptly confirmed in writing by the Authorized Representative, in Investment
Obligations to the extent practicable (but only in Investment Obligations that
are Government Obligations where so restricted by the provisions of this
Indenture), provided that no sale or disposition of any obligation in which
funds are held hereunder shall be required prior to the maturity or repurchase
date thereof because such obligation has ceased to be an Investment Obligation
due to failure of such obligation or the obligor thereunder to continue to be
rated by either Moody's or S&P in the respective investment grade required in

dates when the money held for the credit of such funds or accounts will be
required for the purposes intended.

Under no circumstances may any Investment Obligations in any fund or
account mature beyond the latest maturity date of any Series of Bonds
Outstanding at the time such Investment Obligations are deposited. For the
purposes of this Section 701, the maturity date of repurchase agreements for
Government Obligations or other obligations is the maturity date of such
repurchase agreements and not the maturity date of the underlying Government
Obligation or other obligation.

The Authorized Representative may, at any time, give to the Trustee
written directions respecting the investment of any money required to be
invested hereunder, subject, however, to the provisions of this Indenture, and
the Trustee shall then invest such money as so directed by the Authorized
Representative.

Investment Obligations credited to any fund, account or sub-account
established under this Indenture shall be held by or under the control of the
Trustee and while so held shall be deemed at all times to be part of such fund,
account, or sub-account and, except as otherwise provided in Articles V or VI
hereof, the interest accruing thereon and any profit or loss realized upon the
disposition or maturity of such investment shall be credited to or charged
against such fund, account or sub-account. The Trustee shall sell or reduce to
cash a sufficient amount of such Investment Obligations whenever it shall be
necessary to do so in order to provide moneys to make any payment or transfer of
moneys from any such fund, account or sub-account. The Trustee shall not be
liable or responsible for any loss resulting from any such investment.

Whenever a payment or transfer of money between two or more of the
funds, accounts or sub-accounts established pursuant to Articles V and VI of
this Indenture is permitted or required, such payment or transfer may be made in
whole or in part by the transfer of one or more Investment Obligations at a
value determined in accordance with this Article VII, provided that the
Investment Obligations transferred are those in which moneys of the receiving
fund, account or sub-account could be invested at the date of such transfer.

Section 702. Valuation. For the purpose of determining the amount on
deposit in any fund or account, Investment Obligations shall be valued (a) at
face value if such Investment Obligations mature within six months from the date
of valuation thereof, and (b) if such Investment Obligations mature more than
six months after the date of valuation thereof, at the price at which such
Investment Obligations are redeemable by the holder at his option if so
redeemable, or, if not so redeemable, at the market value of such obligations.

The Trustee shall value the Investment Obligations in the funds and
accounts established under this Indenture on each March 31. In addition, the
Investment Obligations shall be valued by the Trustee at any time requested by
an Authorized Representative on reasonable notice to the Trustee (which period
of notice may be waived or reduced by the Trustee); provided, that the Trustee
shall not be required to value the Investment Obligations more than once in any
calendar quarter. Notwithstanding the foregoing, Investment Obligations in the
Reserve Fund shall be valued on the dates mentioned in Section 603 at the market
value thereof.

Section 703. Investments through Trustee's Bond Department. The Trustee
may make investments permitted by Section 701 through the Underwriter or its own
bond or other investment department or that of any affiliate of the Trustee, as
well as through unrelated parties.

Section 704. Arbitrage Covenant. Each of the Authority and the Trustee
covenants that so long as any of the Bonds remain Outstanding, it will not
knowingly take any action to cause moneys on deposit in any of the funds
established by the Indenture to be used in a manner which will cause any Bond to
be classified as an "arbitrage bond" within the meaning of Section 148 of the
Code. The Trustee shall be entitled to receive and may request from time to time
from the Borrower written directions from Bond Counsel, at the expense of the
Borrower, regarding the interpretation of Section 148 of the Code, and the
Trustee agrees that it will comply with such directions (upon which the Trustee
and the Authority may conclusively rely) so as to enable the Authority to
perform its covenants under this Section. Neither the Authority nor the Trustee,
however, shall have any liability to the Bondholders or the Borrower, or to any
party, for any loss or damage resulting from any investments made by the
Trustee, except, as to the Trustee, loss or damage caused by the willful,
knowing default or gross negligence of the Trustee.


ARTICLE VIII

Discharge of Indenture of Trust

Section 801. Discharge of Indenture of Trust. If (a) all Bonds shall
have become due and payable in accordance with their terms or otherwise as
provided in this Indenture or have been duly called for redemption or
irrevocable instructions to call the Bonds for redemption or pay them at
maturity have been given by the Authority to the Trustee, or (b) the Trustee or
an escrow agent holds cash or Defeasance Obligations the interest on which and
principal at maturity will be sufficient, without reinvestment (1) to redeem in
accordance with the relevant section hereof all such Bonds that have been called
for redemption on the date set for such redemption, (2) to pay at maturity all
such Bonds not irrevocably called for redemption, and (3) to pay interest
accruing on all such Bonds prior to their redemption or payment at maturity, and
(c) the Borrower has paid, or made arrangements satisfactory to each of the
Trustee, the Authority and the Underwriter (including any fees payable to its
officers) to pay to the Trustee, the Authority and the Underwriter (including
any fees payable to its officers) their fees and expenses due hereunder or under
the Loan Agreement, including the costs and expenses of canceling and
discharging this Indenture, then except as hereinafter provided, this Indenture
shall cease to be of further effect and the Trustee shall on demand and at the
expense of the Borrower execute and deliver to the Authority such instruments in
writing acknowledging the satisfaction of this Indenture and as shall be
requisite to cancel any liens securing this Indenture, and assign and deliver to
the Borrower or its affiliates any property at the time subject to this
Indenture that may then be in its possession, except (A) amounts in funds
created by this Indenture required to be paid to the Borrower under Section 608
and (B) funds or securities in which such funds are invested that are held by
the Trustee for the payment of the Bonds and other fees and expenses.

Notwithstanding the discharge of the lien hereof as provided in this
Article VIII, the Trustee shall nevertheless retain such rights, powers and
duties hereunder as may be necessary and convenient for the payment of amounts
due or to become due on the Bonds and the registration, transfer, exchange and
replacement of Bonds as provided herein.


ARTICLE IX

Events of Default and Remedies

Section 901. Events of Default. Each of the following events is an Event
of Default hereunder:

(a) payment of any installment of interest on any Bond shall not
be made by the Authority when the same shall become due and payable;

(b) payment of the principal or the redemption premium, if any, of
any Bond shall not be made by the Authority when the same shall become due and
payable, whether at maturity, by redemption or otherwise;

(c) default in the due and punctual performance of any of the
other covenants, conditions, agreements and provisions contained in this
Indenture and such default shall continue for thirty (30) days (or such further
time as may be granted in writing by the Trustee) after receipt by the Authority
of a written notice from the Trustee specifying such default and requiring the
same to be remedied; or

(d) an "Event of Default" shall have occurred under the Loan
Agreement or any Security Document, and such "Event of Default" shall not have
been remedied or waived.

Section 902. Acceleration. If an Event of Default occurs and is
continuing, the Trustee may, and if requested in writing by the Holders of
twenty-five percent (25%) or more in aggregate principal amount of Bonds then
Outstanding, shall, by notice to the Authority and the Borrower, declare the
entire unpaid principal of and interest on the Bonds due and payable. Upon any
such declaration the Authority shall immediately pay to the Holders the entire
unpaid principal of and accrued interest on the Bonds, but only from the
revenues and receipts herein specifically pledged for such purpose.

Section 903. Other Remedies; Rights of Holders. Upon the occurrence of
an Event of Default, the Trustee may, and, if requested in writing by the
Holders of twenty-five percent (25%) or more in aggregate principal amount of
Bonds then Outstanding and if indemnified as provided in Section 1001(k) shall,
proceed to protect and enforce its rights as the holder of the Notes and the
rights of the Holders, by mandamus or other action, suit or proceeding at law or
in equity for specific performance of any agreement contained herein or in the
Security Documents.

Upon the occurrence of an Event of Default, if requested to do so by
the Holders of twenty-five percent (25%) or more in aggregate principal amount
of Bonds then Outstanding, and if indemnified as provided in Section 1001(k),
the Trustee shall exercise such one or more of the rights and powers conferred
by this Article IX as the Trustee, upon being advised by counsel, shall deem
most expedient in the interests of the Holders.

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

No delay or omission to exercise any right or power accruing upon any
default or Event of Default shall impair any such right or power or shall be
construed to be a waiver of any such default or Event of Default or acquiescence
therein, and every such right and power may be exercised from time to time and
as often as may be deemed expedient. No waiver of any default or Event of
Default hereunder shall extend to or shall affect any subsequent default or
Event of Default or shall impair any rights or remedies consequent thereto.

BY ITS PURCHASE OF ANY BOND, EACH HOLDER HAS AGREED TO PERMIT THE
UNDERWRITER TO SELECT AND DIRECT THE PROCEEDINGS TAKEN BY THE TRUSTEE UPON AN
EVENT OF DEFAULT. THE UNDERWRITER MAY SELECT DIFFERENT REMEDIES FROM THOSE THAT
MAY HAVE BEEN SELECTED BY THE HOLDERS. THE HOLDERS MAY REGAIN THE RIGHT TO
SELECT AND DIRECT PROCEEDINGS BY DELIVERING TO THE TRUSTEE A WRITTEN INSTRUMENT
TAKING THOSE POWERS AWAY FROM THE UNDERWRITER, SIGNED BY THE HOLDERS OF AT LEAST
TWENTY FIVE PERCENT (25%) IN AGGREGATE PRINCIPAL AMOUNT OF THE SERIES A BONDS
AND THE SERIES B BONDS OUTSTANDING. UPON SUCH DELIVERY, THE HOLDERS WILL HAVE
THOSE RIGHTS TO SELECT AND DIRECT PROCEEDINGS AS ARE SET FORTH IN THIS
INDENTURE.

Section 904. Right of Holders to Direct Proceedings. Anything in this
Indenture to the contrary notwithstanding, the Holders of a majority in
aggregate principal amount of Bonds then 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 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 905. Application of Moneys. All moneys received by the Trustee
pursuant to any right given or action taken under the provisions of this Article
IX shall, after payment of the costs and expenses of the proceedings resulting
in the collection of such moneys, the expenses, liabilities and advances
incurred or made by the Trustee and the fees of the Trustee and the expenses of
the Authority in carrying out this Indenture or the Loan Agreement, be deposited
in the Bond Fund. All moneys so deposited in the Bond Fund shall be applied as
follows:

(a) Unless the principal of all the Bonds shall have become or
shall have been declared due and payable, all such moneys shall be applied:

First - To the payment to the Holders entitled
thereto of all installments of interest then due on the Series
A Bonds, including to the extent permitted by law interest on
overdue installments of interest, in the order of the maturity
of the installments of such interest and, if the amount
available shall not be sufficient to pay in full any
particular installment, then to the payment ratably, according
to the amounts due on such installment, to the persons
entitled thereto, without any discrimination or preference
except as to any difference in the respective rates of
interest specified in such Series A Bonds; and

Second - To the payment to the Holders entitled
thereto of the unpaid principal of and premium, if any, on any
of the Series A Bonds that shall have become due (other than
Series A Bonds called for redemption for the payment of which
moneys are held pursuant to the provisions of this Indenture),
in the order of their due dates, with interest on such Series
A Bonds at the respective rates specified therein from the
respective dates on which they became due and, if the amount
available shall not be sufficient to pay in full the Series A
Bonds due on any particular date, together with such interest,
then first to the payment of such interest, ratably, according
to the amount of such interest due on such date, and then to
the payment of such principal, ratably, according to the
amount of such principal due on such date, to the persons
entitled thereto, without any discrimination or preference
except as to any difference in the respective rates of
interest specified in such Series A Bonds; and

Third - To the payment to the Holders entitled
thereto of all installments of interest then due on the Series
B Bonds, including to the extent permitted by law interest on
overdue installments of interest, in the order of the maturity
of the installments of such interest and, if the amount
available shall not be sufficient to pay in full any
particular installment, then to the payment ratably, according
to the amounts due on such installment, to the persons
entitled thereto, without any discrimination or preference
except as to any difference in the respective rates of
interest specified in such Series B Bonds; and

Fourth - To the payment to the Holders entitled
thereto of the unpaid principal of and premium, if any, on any
of the Series B Bonds that shall have become due (other than
Series B Bonds called for redemption for the payment of which
moneys are held pursuant to the provisions of this Indenture),
in the order of their due dates, with interest on such Series
B Bonds at the respective rates specified therein from the
respective dates on which they became due and, if the amount
available shall not be sufficient to pay in full the Series B
Bonds due on any particular date, together with such interest,
then first to the payment of such interest, ratably, according
to the amount of such interest due on such date, and then to
the payment of such principal, ratably, according to the
amount of such principal due on such date, to the persons
entitled thereto, without any discrimination or preference
except as to any difference in the respective rates of
interest specified in such Series B Bonds.

(b) (i) If the principal of all of the Series A Bonds shall have
become due or shall have been declared due and payable, all such moneys shall be
applied to the payment of the principal and interest then due and unpaid on such
Series A Bonds, without preference or priority of principal over interest or of
interest over principal, or of any installment of interest over any other
installment of interest, or of any such Series A Bond over any other such Series
A Bond, ratably, according to the amounts due respectively for principal and
interest, to the persons entitled thereto, without any discrimination or
preference except as to any difference in the respective rates of interest
specified in such Series A Bonds, and (ii) if the principal of all of the Series
B Bonds shall have become due or shall have been declared due and payable and
the Series A Bonds shall have been paid in full, all such moneys shall be
applied to the payment of the principal and interest then due and unpaid on such
Series B Bonds, without preference or priority of principal over interest or of
interest over principal, or of any installment of interest over any other
installment of interest, or of any such Series B Bond over any other such Series
B Bond, ratably, according to the amounts due respectively for principal and
interest, to the persons entitled thereto, without any discrimination or
preference except as to any difference in the respective rates of interest
specified in such Series B Bonds.

(c) If the principal of all of any Series of the Bonds shall have
been declared due and payable and if such declaration shall thereafter have been
rescinded and annulled under the provisions of this Article IX, then, subject to
the applicable provisions of Section 905(b), in the event that the principal of
all such Bonds shall later become due or be declared due and payable, the moneys
shall be applied in accordance with the provisions of Section 905(a).

Whenever moneys are to be applied pursuant to the provisions of this
Section 905, such moneys shall be applied at such times and from time to time as
the Trustee shall determine, having due regard to the amount of such moneys
available for application and the likelihood of additional moneys becoming
available for such application in the future. Whenever the Trustee shall apply
such moneys, it shall fix the date (which shall be an Interest Payment Date
unless it shall deem another date more suitable) on which such application is to
be made and on such date interest on the amounts of principal to be paid on such
dates shall cease to accrue. The Trustee shall give such notice as it may deem
appropriate of the deposit with it of any such moneys and of the fixing of any
such date, and shall not be required to make payment to any Holder until such
Bond shall be presented to the Trustee for appropriate endorsement or for
cancellation if fully paid.

Whenever all Bonds have been paid under the provisions of this Section
905 and all expenses and charges of the Trustee have been paid, any balance
remaining in the several funds created under this Indenture shall be paid to the
Borrower as provided in Section 608.

Section 906. Remedies Vested in Trustee. All rights 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
such Bonds or the production thereof in any trial or other proceeding relating
thereto and any such suit or proceeding instituted by the Trustee may be brought
in its name as Trustee without the necessity of joining as plaintiffs or
defendants any Holders, and any recovery of judgment shall be for the equal
benefit of the Holders of the Series A Bonds first, and, if the entire principal
amount of, interest and premium, if any, on the Series A Bonds has been paid,
for the equal benefit of the Holders of the Series B Bonds, subject to the
provisions of Section 905.

Section 907. Limitation on Suits. Except to enforce the rights given
under Section 908, no Holder shall have any right to institute any action, suit
or proceeding at law or in equity for the enforcement of this Indenture or for
the execution of any trust thereof or any other remedy hereunder, unless (a) a
default has occurred and is continuing of which the Trustee has been notified as
provided in Section 1001(h), or of which by such section it is deemed to have
notice, (b) such default has become an Event of Default and the Holders of
twenty-five percent (25%) or more in aggregate principal amount of Bonds then
Outstanding have made written request to the Trustee and offered it reasonable
opportunity either to proceed to exercise the powers hereinbefore granted or to
institute such action, suit or proceeding in its own name, (c) such Holders have
offered to the Trustee indemnity as provided in Section 1001(k), (d) the Trustee
has for thirty (30) days after such notice failed or refused to exercise the
powers hereinbefore granted, or to institute such action, suit or proceeding in
its own name, (e) no direction inconsistent with such written request has been
given to the Trustee during such 30-day period by the Holders of a majority in
aggregate principal amount of the Bonds then Outstanding, and (f) notice of such
action, suit or proceeding is given to the Trustee, it being understood and
intended that no one or more Holders of the Bonds shall have any right in any
manner whatsoever to affect, disturb or prejudice this Indenture by its, his or
their action or to enforce any right hereunder except in the manner herein
provided, and that all proceedings at law or in equity shall be instituted and
maintained in the manner herein provided and for the equal benefit of the
Holders of all Bonds then Outstanding. The notification, request and offer of
indemnity set forth above, at the option of the Trustee, shall 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 any other
remedy hereunder.

BY ITS PURCHASE OF ANY BOND, EACH HOLDER HAS AGREED TO PERMIT THE
UNDERWRITER TO SELECT AND DIRECT THE PROCEEDINGS TAKEN BY THE TRUSTEE UPON AN
EVENT OF DEFAULT. THE UNDERWRITER MAY SELECT DIFFERENT REMEDIES FROM THOSE THAT
MAY HAVE BEEN SELECTED BY THE HOLDERS. THE HOLDERS MAY REGAIN THE RIGHT TO
SELECT AND DIRECT PROCEEDINGS BY DELIVERING TO THE TRUSTEE A WRITTEN INSTRUMENT
TAKING THOSE POWERS AWAY FROM THE UNDERWRITER, SIGNED BY THE HOLDERS OF AT LEAST
TWENTY FIVE PERCENT (25%) IN AGGREGATE PRINCIPAL AMOUNT OF THE SERIES A BONDS
AND THE SERIES B BONDS OUTSTANDING. UPON SUCH DELIVERY, THE HOLDERS WILL HAVE
THOSE RIGHTS TO SELECT AND DIRECT PROCEEDINGS AS ARE SET FORTH IN THIS
INDENTURE.

Section 908. Unconditional Right to Receive Principal, Premium and
Interest. Nothing in this Indenture shall affect or impair the right of any
Holder to enforce, by action at law, payment of any Bond held by such Holder at
and after the maturity thereof, or on the date fixed for redemption or upon the
same being declared due prior to maturity as herein provided, or the obligation
of the Authority to pay such Bond issued hereunder to the respective Holders
thereof at the time and place, from the source, in the priority and in the
manner expressed herein and in such Bonds.

Section 909. Termination of Proceedings. In case the Trustee shall have
proceeded to enforce any right under this Indenture or the Security Documents
and such proceedings shall have been discontinued or abandoned for any reason or
shall have been determined adversely to the Trustee, then and in every such case
the Authority, the Borrower and the Trustee shall be restored to their former
positions and rights hereunder, and all rights, remedies and powers of the
Trustee shall continue as if no such proceedings had been taken.

Section 910. Waivers of Events of Default. The Trustee may, in its
discretion and shall, at the direction of the Underwriter if the Underwriter
then controls the direction and selection of remedies hereunder as contemplated
by Section 903 hereof, waive any Event of Default hereunder and its consequences
and rescind any declaration of maturity of principal of and interest on the
Bonds and shall do so at the written request of the Holders of (a) a majority in
aggregate principal amount of Bonds then Outstanding with respect to which
default in the payment of principal, premium, if any, or interest exists, or (b)
a majority in aggregate principal amount of Bonds then Outstanding in the case
of any other default; provided, that:

(1) unless the Underwriter controls the direction and
selection of remedies hereunder (in which case any default may be
waived by the Underwriter) there shall not be waived without the
consent of the Holders of all such Bonds then Outstanding (A) any
Event of Default in the payment of the principal of any such
Outstanding Bonds, or (B) any default in the payment when due of the
interest on any Bonds unless, prior to such waiver or rescission,

(i) there shall have been paid or provided for all
arrears of interest with interest (to the extent permitted
by law) at the rate borne by such Bonds on overdue
installments of principal or interest, all arrears of
principal and premium, if any, and all expenses of the
Trustee and the Authority in connection with such default,
and

(ii) in case of any such waiver or rescission or in
case of any discontinuance, abandonment or adverse
determination of any proceeding taken by the Trustee on
account of any such default, the Authority, the Trustee and
the Holders of the Bonds shall be restored to their former
positions and rights hereunder respectively; and

(2) no acceleration under Section 902 shall be rescinded by
the Trustee unless directed to do so by the Holders of a majority in
aggregate principal amount of Bonds then Outstanding.

No such waiver or rescission shall extend to any subsequent or other
default or impair any right consequent thereon.

BY ITS PURCHASE OF ANY BOND, EACH HOLDER HAS AGREED TO PERMIT THE
UNDERWRITER TO SELECT AND DIRECT THE PROCEEDINGS TAKEN BY THE TRUSTEE UPON AN
EVENT OF DEFAULT. THE UNDERWRITER MAY SELECT DIFFERENT REMEDIES FROM THOSE THAT
MAY HAVE BEEN SELECTED BY THE HOLDERS. THE HOLDERS MAY REGAIN THE RIGHT TO
SELECT AND DIRECT PROCEEDINGS BY DELIVERING TO THE TRUSTEE A WRITTEN INSTRUMENT
TAKING THOSE POWERS AWAY FROM THE UNDERWRITER, SIGNED BY THE HOLDERS OF AT LEAST
TWENTY FIVE PERCENT (25%) IN AGGREGATE PRINCIPAL AMOUNT OF THE SERIES A BONDS
AND THE SERIES B BONDS OUTSTANDING. UPON SUCH DELIVERY, THE HOLDERS WILL HAVE
THOSE RIGHTS TO SELECT AND DIRECT PROCEEDINGS AS ARE SET FORTH IN THIS
INDENTURE.

Section 911. Notice of and Opportunity to Cure Defaults. Anything
herein to the contrary notwithstanding, no default specified in Section 901(c)
on the part of the Authority shall constitute an Event of Default until (a)
notice of such default shall be given (1) by the Trustee to the Authority and
the Borrower or (2) by the Holders of twenty-five percent (25%) or more in
aggregate principal amount of the Bonds then Outstanding to the Trustee, the
Authority and the Borrower and (b) the Authority and the Borrower shall have had
thirty (30) days after such notice to correct such default or cause such default
to be corrected, and shall not have corrected such default or caused such
default to be corrected within such period; provided, that if any default
specified in Section 901(c) shall be such that it can be corrected but cannot be
corrected within such period, it shall not constitute an Event of Default if
corrective action is instituted by the Authority or the Borrower within such
period and diligently pursued until such default is corrected.

With regard to any alleged default concerning which notice is given to
the Borrower under this Section 911, the Borrower may, but is not required, to
perform any covenant, condition or agreement, the nonperformance of which is
alleged in such notice to constitute a default.


ARTICLE X
The Trustee

Section 1001. Acceptance of Trusts and Obligations. The Trustee hereby
accepts the trusts and obligations imposed upon it by this Indenture, the Loan
Agreement and the Continuing Disclosure Agreement and agrees to perform such
trusts and obligations, but only upon and subject to the following express terms
and conditions and no implied covenants or obligations shall be read into this
Indenture, the Loan Agreement or the Continuing Disclosure Agreement against the
Trustee:

(a) The Trustee, prior to the occurrence of an Event of Default
and after the waiver or curing of all Events of Default that may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture and the Loan Agreement and as a corporate trustee
ordinarily would perform such duties under a corporate indenture. In case an
Event of Default has occurred (which has not been waived or cured) 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 and use under the circumstances in the conduct of his own affairs.

(b) The Trustee may execute any of the trusts or powers hereof and
perform any of its duties by or through attorneys, agents or receivers selected
with due care or by or through employees but shall be answerable for the conduct
of such employees in accordance with the standards specified above, and shall be
entitled to act on the opinion or advice of its counsel concerning all matters
of trust hereof and the duties hereunder, and may in all cases pay and be
reimbursed for reasonable compensation to all such attorneys, agents, receivers,
employees and counsel as may reasonably be employed in connection with the trust
hereof. The Trustee may act on an Opinion of Counsel and shall not be
responsible for any loss or damage resulting from any action or nonaction by it
taken or omitted to be taken in good faith in reliance on such Opinion of
Counsel.

(c) The Trustee shall not be responsible for any recital herein or
in the Bonds (except with respect to the certificate of the Trustee endorsed on
the Bonds), or for the recording, re-recording, filing or re-filing of any
document or instrument, or for insuring the Project or collecting any insurance
moneys, or for the validity of the execution by the Authority of this Indenture
or of any supplements hereto or instruments of further assurance, or for the
sufficiency of the security for the Bonds issued hereunder or intended to be
secured hereby, or for the value of or title to the Project or otherwise as to
the maintenance of the security hereof, except that in the event the Trustee
takes possession of any part of the Project pursuant to any provision of this
Indenture, the Loan Agreement or the Security Documents, it shall use due
diligence in preserving such part. The Trustee shall not be bound to ascertain
or inquire as to the observance or performance of any covenants, conditions or
agreements on the part of the Authority, the Borrower, or any other party under
the Financing Documents to which they are parties, except as herein and therein
set forth. The Trustee shall not be responsible or liable for any loss suffered
in connection with any investment of moneys made by it in accordance with the
terms of this Indenture.

(d) The Trustee shall not be accountable for the use of any Bonds
authenticated or delivered hereunder. The bank or trust company acting as
Trustee and its directors, officers, employees or agents may in good faith buy,
sell, own, hold and deal in the Bonds and may join in any action that any Holder
may be entitled to take with like effect as if such bank or trust company were
not the Trustee. To the extent permitted by law, such bank or trust company may
also receive tenders and purchase in good faith Bonds from itself, including any
department, affiliate or subsidiary, with like effect as if it were not the
Trustee.

(e) The Trustee shall be protected in acting on any resolution,
opinion, notice, request, consent, certificate, order, affidavit, letter,
telegram or other paper or document or any oral or telephonic communication
permissible herein reasonably believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons and such communication
shall be 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 under this Indenture. Any action taken
by the Trustee pursuant to this Indenture at the request or authority or consent
of any person who at the time of making such request or giving such authority or
consent is the Holder of any Bond shall be conclusive and binding on all future
Holders of the same Bond and on Bonds issued in exchange therefor or in place
thereof.

(f) 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 on a certificate signed on behalf of the Authority by
its Chairman or Vice Chairman, or such other person or persons as may be
designated for such purposes by resolution of the Authority, or a certificate
signed on behalf of the Borrower by its Authorized Representative or such other
person or persons as may be designated for such purposes by resolution of the
Borrower 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) below, or of which by such subsection it is deemed to have
notice, may also 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 or an Assistant Secretary of the Authority to the effect that a
resolution in the form therein set forth has been adopted by the Authority as
conclusive evidence that such resolution has been duly adopted and is in full
force and effect.

(g) The permissive right of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty, and the Trustee shall not be
answerable for other than its negligence or willful misconduct.

(h) The Trustee shall not be required to take notice or be deemed
to have notice of any default hereunder, except failure by the Authority to
cause to be made any of the payments to the Trustee required to be made by
Article IV or failure by the Authority or the Borrower to file with the Trustee
any document required by this Indenture or the Loan Agreement unless the Trustee
shall be notified of such default by the Authority or the Holders of ten percent
(10%) or more in aggregate principal amount of the Bonds then Outstanding.

(i) The Trustee shall not be required to give any bond or surety
with respect to the execution of its rights and obligations hereunder.

(j) Notwithstanding any other provision of this Indenture, the
Trustee shall have the right, but shall not be required, to demand, as a
condition of any action by the Trustee with respect to 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, appraisals or other information, or corporate action or evidence
thereof, in addition to that required by the terms hereof.

(k) Before taking any action under this Indenture, the Trustee may
require that satisfactory indemnity be furnished to it for the reimbursement of
all expenses to which it may be put and to protect it against all liability by
reason of any action so taken, except liability which is adjudicated to have
resulted from its negligence or willful default.

(l) All moneys received by the Trustee shall, until used or
applied or invested as herein provided, be held in trust in the manner and for
the purposes for which they were received but need not be segregated from other
funds except to the extent required by this Indenture or law. The Trustee shall
not be under any liability for interest on any moneys received hereunder except
such as may be agreed upon.

Section 1002. Fees, Charges and Expenses of Trustee. Absent a specific
agreement as to payment of the Trustee's fees, charges and expenses, the Trustee
and any paying agents shall be entitled to payment and reimbursement for
reasonable fees for services rendered under this Indenture, the Loan Agreement,
the Security Documents and the Continuing Disclosure Agreement and all advances,
counsel fees and disbursements and other expenses reasonably made or incurred by
the Trustee in connection with such services. Upon an Event of Default, but only
upon an Event of Default, the Trustee shall have a first lien with right of
payment prior to payment on account of principal of, or premium, if any, and
interest on any Bond upon the trust estate created by this Indenture for the
foregoing fees, charges and expenses incurred by the Trustee. When the Trustee
incurs expenses or renders services after the occurrence of an Event of Default
caused by the occurrence of an "Event of Default" specified in Sections 6.1(d)
or 6.1(e) of the Loan Agreement, the expenses and the compensation for the
services are intended to constitute expenses of administration under any federal
or state bankruptcy, insolvency, arrangement, moratorium, reorganization or
other debtor relief law.

Section 1003. Notice Required of Trustee. If the Borrower fails to make
any payment on the Notes on the day such payment is due and payable, the Trustee
shall give notice thereof by telephone, facsimile or telegram to the Borrower
within three (3) business days and shall confirm such notice in writing by first
class mail. In the event of (a) the continuance for ten (10) days of any such
failure to make payment, or (b) notification to the Trustee by the Holders of
ten percent (10%) or more in aggregate principal amount of the applicable Series
of Bonds then Outstanding of any default hereunder, the Trustee shall give
notice thereof to each Holder of such Series of Bonds, as appropriate, and the
Underwriter; provided, that if the Trustee, in its sole discretion, determines
that such notice may adversely affect the interests of the Holders of a majority
in principal amount of such Bonds, the Trustee will not give notice to such
Bondholders unless requested to do so by the Holders of ten percent (10%) or
more in aggregate principal amount of such Bonds then Outstanding. Failure of
the Trustee to give the notice provided herein shall not subject the Trustee to
any liability to any person, including the Authority, the Borrower, the Holders,
or the Underwriter, nor shall such failure relieve the Authority or the Borrower
of their obligations hereunder or under the other Financing Documents.

Section 1004. Intervention by Trustee. In any judicial proceeding to
which the Authority or the Borrower is a party and which in the opinion of the
Trustee has a substantial bearing on the interests of the Holders of the Bonds,
the Trustee may intervene on behalf of such Holders.

Section 1005. Merger or Consolidation of Trustee. Any corporation or
association into which the corporate trust business of the Trustee may be
converted or merged, or with which it may be consolidated, or to which it may
sell or transfer its corporate trust business and assets as a whole or
substantially as a whole, or any corporation or association resulting from any
such conversion, sale, merger, consolidation or transfer to which it is a party
shall be and become successor Trustee hereunder and vested with all the trusts,
powers, discretion, 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 1006. Resignation by Trustee. The Trustee may at any time
resign from the trusts hereby created with thirty (30) days' written notice to
the Authority, the Borrower and each Holder, but such resignation shall take
effect only upon the appointment of a successor or temporary Trustee by the
Holders, with the consent of the Authority, or by the Authority, at the
direction of the Borrower; provided, that if no such appointment has been made
at the end of such 30-day period, the Trustee may petition a court of competent
jurisdiction for appointment of a successor or temporary Trustee.

Section 1007. Removal of Trustee. The Trustee may be removed at any
time by an instrument or concurrent instruments in writing filed with the
Authority, (A) signed by the Holders of a majority in aggregate principal amount
of Bonds then Outstanding or (B) signed by the Borrower, so long as no Event of
Default has occurred and in continuing.

Section 1008. Appointment of Successor Trustee by Holders; Temporary
Trustee. In case the Trustee hereunder shall resign, be removed, be dissolved,
be in course of dissolution or liquidation or otherwise become incapable of
acting hereunder, or in case it shall be taken under the control of any public
officer or officers or of a receiver appointed by a court, a successor may be
appointed by the Holders of a majority in aggregate principal amount of Bonds
then Outstanding, by an instrument or concurrent instruments in writing signed
by such Holders; provided, that in case of such vacancy, the Authority, at the
direction of the Borrower, by an instrument approved by affirmative vote of the
Authority, may appoint a temporary Trustee to fill such vacancy until a
successor Trustee shall be appointed by the Holders in the manner provided
above, and any such temporary Trustee so appointed by the Authority at the
direction of the Borrower, shall immediately and without further act be
superseded by the Trustee so appointed by such Holders. Every such Trustee
appointed pursuant to this Section 1008 shall be, if there be such an
institution willing, qualified and able to accept the trust upon reasonable or
customary terms, (a) a bank or trust company in good standing and having a
combined capital, surplus and undivided profits of not less than $50,000,000, or
(b) a subsidiary trust company under the Trust Subsidiary Act, Article 3.1,
Chapter 2, Title 6.1, Code of Virginia of 1950, as amended, whose parent
Virginia bank or bank holding company has undertaken to be responsible for the
acts of such subsidiary trust company pursuant to the provisions of Section
6.1-32.7(a) of the Trust Subsidiary Act, or any successor provision of law, and
whose combined capital, surplus and undivided profits, together with that of its
parent Virginia bank or bank holding company, as the case may be, is not less
than $50,000,000 and which is otherwise qualified to serve as Trustee under the
applicable provisions of the Act.

Section 1009. Concerning any Successor Trustee. Every successor Trustee
appointed hereunder shall execute, acknowledge and deliver to its predecessor
and also to the Authority an instrument in writing accepting such appointment
hereunder, and thereafter such successor, without any further act, deed or
conveyance, shall become fully vested with all the properties, rights, powers,
trusts, duties and obligations of its predecessor, but such predecessor shall,
nevertheless, on the written request of the Authority or the successor Trustee,
execute and deliver an instrument transferring to such successor Trustee all the
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 an instrument in writing from the
Authority be required by any successor Trustee for more fully and certainly
vesting in such successor the properties, rights, powers and duties hereby
vested or intended to be vested in the predecessor, the Authority shall execute,
acknowledge and deliver such instrument in writing, provided that such
instrument is limited to provisions necessary for the aforementioned purpose and
provided that such instrument shall not modify any provision in the Indenture or
any of the Financing Documents, nor shall such provision impose any obligation
on the Authority not already imposed by this Indenture or the Financing
Documents. 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 X, shall be filed and/or recorded
by the successor Trustee in each recording office where the Indenture of Trust
may have been filed and/or recorded.

Section 1010. Successor Trustee as Custodian of Funds. In the event of
a change in the office of Trustee, the predecessor Trustee which has resigned or
been removed shall cease to be custodian of the several funds created under this
Indenture and the successor Trustee shall become such custodian.

Section 1011. Removal and Resignation Not To Affect Fees. No
resignation or removal of the Trustee shall affect the obligation of the
Borrower to pay the Trustee fees that have accrued prior to the effective date
of such resignation or removal and reasonable expenses of transferring funds,
records and other necessary items and information to the successor Trustee
hereunder.

Section 1012. Right of Trustee To Pay Taxes and Other Charges. In case
any tax, assessment or governmental or other charge on any part of the Project
is not paid as required herein, the Trustee may pay such tax, assessment or
governmental charge, without prejudice, however, to any rights of the Trustee or
the Holders hereunder arising in consequence of such failure. Any amount at any
time so paid under this Section 1012, with interest thereon from the date of
payment at the rate equal to the Prime Rate, as defined in the Loan Agreement,
plus one percent (1%) per year, shall become additional indebtedness secured by
this Indenture and such indebtedness shall be given a preference in payment over
any of the Bonds, and shall be paid out of the proceeds of revenues and receipts
collected from the security for the Bonds, if not otherwise caused to be paid,
but the Trustee shall be under no obligation to make any such payment unless it
shall have been requested to do so by the Holders of ten percent (10%) or more
in aggregate principal amount of Bonds then Outstanding and shall have been
provided with adequate funds for the purpose of such payment.

Section 1013. Trustee Protected in Relying on 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, the withdrawal of cash hereunder or
the taking of any other action by the Trustee as provided hereunder.

consent of, or notice to, any of the Holders, enter into an agreement or
agreements supplemental to this Indenture for any one or more of the following
purposes:

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

(b) To grant to or confer on the Trustee for the benefit of the
Holders any additional rights, remedies, powers or authority that may lawfully
be granted to or conferred on the Holders or the Trustee or either of them;

(c) To subject to the lien of this Indenture additional revenues,
properties or collateral;

(d) To modify, amend or supplement this Indenture in such manner
as required or desirable to permit the qualification hereof under the Trust
Indenture Act of 1939, as amended, or any similar federal statute hereafter in
effect or the exemption of the Bonds under any state securities ("Blue Sky")
law, and, if they so determine, to add to this Indenture such other terms,
conditions and provisions as may be required by the Trust Indenture Act of 1939,
as amended, or similar federal statute or state securities law;

(e) To establish, discontinue or modify the use of a book-entry
system to identify the owner of a beneficial interest in any Bond; and

Section 1102. Supplemental Indentures of Trust Requiring Consent of
Holders; Bonds Outstanding. Exclusive of supplemental indentures of trust
described in Section 1101 and subject to the terms and provisions contained in
this Section 1102 and Section 1104, the Holders of a majority in aggregate
principal amount of Bonds then Outstanding shall have the right, notwithstanding
any other provision of this Indenture, to consent to and approve the execution
by the Authority and the Trustee of such other agreement or agreements
supplemental hereto as shall be deemed necessary or desirable by the Authority
for the purpose of modifying, altering, amending, adding to or rescinding any of
the terms or provisions contained in this Indenture or in any supplemental
indenture of trust; provided, that without the consent of all the Holders of the
Bonds, no amendment shall permit (a) an extension of the maturity of the
principal of or the interest on any Bond, or (b) a reduction in the principal
amount of, or premium, if any, on any Bond or the rate of interest thereon, or
(c) an extension of time or a reduction in amount of any payment required by any
mandatory sinking fund redemption obligation that may be applicable to any
Bonds, or (d) a privilege or priority of any Bond over any other Bond or (e) a
reduction in the aggregate principal amount of Bonds required for consent to
such supplemental indenture of trust.

If at any time the Authority shall request the Trustee to enter into
any such supplemental indenture of trust for any of the purposes of this Section
1102, the Trustee shall, upon being satisfactorily indemnified by the Borrower
with respect to expenses, cause notice of the proposed execution of such
supplemental indenture of trust to be sent to each Holder by registered or
certified mail to the address of such Holder as it appears on the registration
books; provided, that failure to give such notice by mailing, or any defect
therein, shall not affect the validity of any proceedings pursuant hereto. Such
notice shall briefly set forth the nature of the proposed supplemental indenture
of trust and shall state that copies thereof are on file at the principal
corporate trust office of the Trustee for inspection by all Holders. If, within
sixty (60) days or such longer period as shall be prescribed by the Authority
following the giving of such notice, the Holders of the requisite percentage in
aggregate principal amount of the Bonds then Outstanding shall have consented to
and approved the execution thereof as herein provided, no Holder 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 Authority from executing
such supplemental indenture of trust or from taking any action pursuant to the
provisions thereof. Upon the execution of any such supplemental indenture of
trust, this Indenture shall be deemed to be modified and amended in accordance
therewith.

Bonds owned or held by or for the account of the Authority, the
Borrower or any person controlling, controlled by or under common control with
either of them shall not be deemed Outstanding for the purpose of consent or any
calculation of Outstanding Bonds provided for in this Article XI or in Article
XII, unless such persons own all of the Outstanding Bonds. At the time of any
such calculation, the Authority and the Borrower shall furnish the Trustee a
certificate of the Authority or the Borrower, as applicable, upon which the
Trustee may rely, describing all such Bonds to be excluded.

Section 1103. Amendment by Unanimous Consent. Notwithstanding any other
provision in this Indenture except Section 1104, the Authority and the Trustee
may enter into any supplemental indenture of trust to this Indenture upon
receipt of the consent of all the Holders.

Section 1104. Opinion of Counsel and Consent of the Borrower Required.
Notwithstanding any other provision of this Indenture, neither the Trustee nor
the Authority shall (a) execute any supplemental indenture of trust to this
Indenture unless there shall have been filed with the Trustee and the Authority
(i) an Opinion of Counsel stating that such supplemental indenture of trust is
authorized or permitted by this Indenture and complies with its terms and that
upon execution it will be valid and binding on the Authority in accordance with
its terms, which Opinion of Counsel, to the extent appropriate, may rely on the
Trustee's determination that such amendment, change or modification is as
described in Section 1101(f), if applicable, and (ii) an opinion of Bond Counsel
stating that such supplemental indenture of trust will not have an adverse
effect on the exclusion of interest on the Bonds from gross income for purposes
of federal income taxation, or (b) execute any supplemental indenture of trust
without the consent of the Borrower.

Section 1105. Trustee's Obligation Regarding Supplemental Indentures of
Trust and Amendments to Loan Agreement and Note. If the Trustee believes in good
faith that such action is or may be, in any material respect, adverse to or
increase or otherwise materially alter its rights, duties and immunities, the
Trustee shall not be required (a) to enter into any supplemental indenture of
trust permitted by this Article XI or (b) to consent to any amendment, change or
modification of the other Financing Documents permitted by Article XII.


ARTICLE XII

Security Documents without the written approval or consent of the Holders of a
majority in aggregate principal amount of Bonds then outstanding given and
procured as provided in Section 1102. If the Authority or the Borrower shall
request the consent of the Trustee to any such proposed amendment, change or
modification, the Trustee shall, upon being satisfactorily indemnified with
respect to expenses, cause notice of such proposed amendment, change or
modification to be given in the same manner as provided by Section 1102.

Section 1203. Limitation on Amendments/Amendment by Unanimous Consent.

Bonds as the same become due, without the consent of the Holders of all of the
Bonds then Outstanding.

Notwithstanding any other provision of this Indenture except Section
1204, the Authority and the Trustee may consent to any amendment, change or

filed with the Trustee and the Authority (i) an Opinion of Counsel that such
amendment, change or modification is authorized or permitted by this Indenture
and the Loan Agreement, the Notes or the Security Documents, as applicable, and
complies with their respective terms and that on execution it will be valid and
binding on the party or parties executing it in accordance with its terms, which
Opinion of Counsel may rely on the Trustee's determination that such amendment,
change or modification will not prejudice in any material respect the rights of
the Holders, if applicable, and (ii) an Opinion of Bond Counsel stating that
such amendment, change or modification will not have an adverse effect on the
exclusion of interest on the Bonds from gross income for purposes of federal
income taxation.
