shall sign the Senior Secured Notes for the Issuers by manual or facsimile
signature.

         If the Responsible Officer whose signature is on a Senior Secured Note
is no longer a Responsible Officer at the time a Senior Secured Note is
authenticated, the Senior Secured Note shall nevertheless be valid.

         A Senior Secured Note shall not be valid until authenticated by the
manual signature of the Trustee. The signature shall be conclusive evidence that
the Senior Secured Note has been authenticated under this Indenture.

         The Trustee shall, upon a written order of the Issuers signed by one
Responsible Officer of each Issuer (an "Authentication Order"), authenticate
Senior Secured Notes for original issue up to the aggregate principal amount
stated in paragraph 4 of the Senior Secured Notes. The aggregate principal
amount of Senior Secured Notes outstanding at any time may not exceed such
amount except as provided in Section 2.07 hereof.

         The Trustee may appoint an authenticating agent acceptable to the
Issuers to authenticate Senior Secured Notes. An authenticating agent may
authenticate Senior Secured Notes whenever the Trustee may do so. Each reference
in this Indenture to authentication by the Trustee includes authentication by
such agent. An authenticating agent has the same rights as an Agent to deal with
Holders or an Affiliate of the Issuers.

         Section 2.03. Registrar and Paying Agent. The Issuers shall maintain an
office or agency where Senior Secured Notes may be presented for registration of
transfer or for exchange ("Registrar") and an office or agency where Senior
Secured Notes may be presented for payment ("Paying Agent"). The Registrar shall
keep a register of the Senior Secured Notes and of their transfer and exchange.
The Issuers may appoint one or more co-registrars and one or more additional
paying agents. The term "Registrar" includes any co-registrar and the term
"Paying Agent" includes any additional paying agent. The Issuers may change any
Paying Agent or Registrar without notice to any Holder. The Issuers shall notify
the Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Issuers fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Issuers or any of
their Affiliates may act as Paying Agent or Registrar.

         The Issuers initially appoint The Depository Trust Company ("DTC") to
act as Depositary Agent with respect to the Global Notes.

         The Issuers initially appoint the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Notes.

         Section 2.04. Paying Agent to Hold Money in Trust. The Issuers shall
require each Paying Agent other than the Trustee to agree in writing that the
Paying Agent will hold in trust for the benefit of Holders or the Trustee all
money held by the Paying Agent for the payment of principal, premium, if any, or
interest on the Senior Secured Notes, and will notify the Trustee of any default
by the Issuers in making any such payment. While any such default continues, the
Trustee may require a Paying Agent to pay all money held by it to the Trustee.
The Issuers at any time may require a Paying Agent to pay all money held by it
to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other
than one of the Issuers or an Affiliate of the Issuers) shall have no further
liability for the money. If one of the Issuers or an Affiliate of the Issuers
acts as Paying Agent, it shall segregate and hold in a separate trust fund for
the benefit of the Holders all money held by it as Paying Agent. Upon any
bankruptcy or reorganization proceedings relating to the Issuers, the Trustee
shall serve as Paying Agent for the Senior Secured Notes.

         Section 2.05. Holder Lists. The Trustee shall preserve in as current a
form as is reasonably practicable the most recent list available to it of the
names and addresses of all Holders and shall otherwise comply with TIA (S)
312(a). If the Trustee is not the Registrar, the Issuers shall furnish to the
Trustee at least seven (7) Business Days before each interest payment date and
at such other times as the Trustee may request in writing, a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of the Holders of Senior Secured Notes and the Issuers shall otherwise
comply with TIA (S) 312(a).

         Section 2.06.  Transfer and Exchange.

         (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary Agent to a nominee of the
Depositary Agent, by a nominee of the Depositary Agent to the Depositary Agent
or to another nominee of the Depositary Agent, the Depositary Agent or any such
nominee to a successor Depositary Agent or a nominee of such successor
Depositary Agent. All Global Notes will be exchanged by the Issuers for
Definitive Notes if (i) the Issuers deliver to the Trustee notice from the
Depositary Agent that it is unwilling or unable to continue to act as Depositary
Agent or that it is no longer a clearing agency registered under the Exchange
Act and, in either case, a successor Depositary Agent is not appointed by the
Issuers within 120 days after the date of such notice from the Depositary Agent
or (ii) the Issuers in their sole discretion determine that the Global Notes (in
whole but not in part) should be exchanged for Definitive Notes and deliver a
written notice to such effect to the Trustee; provided that in no event shall
the Regulation S Temporary Global Note be exchanged by the Issuers for
Definitive Notes

prior to (x) the expiration of the Restricted Period and (y) the receipt by the
Registrar of any certificates required pursuant to Rule 903(c)(3)(ii)(B) under
the Securities Act. Upon the occurrence of either of the preceding events in (i)
or (ii) above, Definitive Notes shall be issued in such names as the Depositary
Agent shall instruct the Trustee. Global Notes also may be exchanged or
replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof.
Every Senior Secured Note authenticated and delivered in exchange for, or in
lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or
Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form
of, and shall be, a Global Note. A Global Note may not be exchanged for another
Note other than as provided in this Section 2.06(a), however, beneficial
interests in a Global Note may be transferred and exchanged as provided in
Section 2.06(b) or (c) hereof.

         (b)  Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes shall be
effected through the Depositary Agent, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes shall be subject to restrictions on transfer comparable to those
set forth herein to the extent required by the Securities Act. Transfers of
beneficial interests in the Global Notes also shall require compliance with
either subparagraph (i) or (ii) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

              (i)   Transfer of Beneficial Interests in the Same Global Note.

         interest in the same Restricted Global Note in accordance with the
         transfer restrictions set forth in the Private Placement Legend;
         provided, however, that prior to the expiration of the Restricted
         Period, transfers of beneficial interests in the Temporary Regulation S
         Global Note may not be made to a U.S. Person or for the account or
         benefit of a U.S. Person (other than an Initial Purchaser). Beneficial
         interests in any Unrestricted Global Note may be transferred to Persons
         who takes delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Note. No written orders or instructions shall be
         required to be delivered to the Registrar to effect the transfers
         described in this Section 2.06(b)(i).

              (ii)  All Other Transfers and Exchanges of Beneficial Interests
         in Global Notes. In connection with all transfers and exchanges of

          be credited with such increase or (B) (1) a written order from a

          instructions given by the Depositary Agent to the Registrar containing
          information regarding the Person in whose name such Definitive Note
          shall be registered to effect the transfer or exchange referred to in

          Registrar of the instructions contained in the Letter of Transmittal
          delivered by the Holder of such beneficial interests in the Restricted
          Global Notes. Upon satisfaction of all of the requirements for
          transfer or exchange of beneficial interests in Global Notes contained
          in this Indenture and the Senior Secured Notes or otherwise applicable
          under the Securities Act, the Trustee shall adjust the principal
          amount of the relevant Global Note(s) pursuant to Section 2.06(h)

                (iii) Regulation S Temporary Global Note Legend. The
          Regulation S Temporary Global Note shall bear a legend in
          substantially the following form:

          "THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND
          THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED
          NOTES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER
          THE HOLDER NOR THE BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY
          GLOBAL NOTE SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON."

          (h)   Cancellation and/or Adjustment of Global Notes. At such time as
all beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Senior Secured Notes represented by such Global
Note shall be reduced accordingly and an endorsement shall be made on such
Global Note by the Trustee or by the Depositary Agent at the direction of the
Trustee to reflect such reduction; and if the beneficial interest is being
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note, such other Global Note
shall be increased accordingly and an endorsement shall be made on such Global
Note by the Trustee or by the Depositary Agent at the direction of the Trustee
to reflect such increase.

          (i)   General Provisions Relating to Transfers and Exchanges.

                  (i)  To permit registrations of transfers and exchanges, the
          Issuers shall execute and the Trustee shall authenticate Global Notes
          and Definitive Notes upon the Issuers' order or at the Registrar's
          request.

                 (ii)  No service charge shall be made to a Holder of a
          beneficial interest in a Global Note or to a Holder of a Definitive
          Note for any registration of transfer or exchange, but the Issuers may
          require payment of a sum sufficient to cover any transfer tax or
          similar governmental charge payable in connection therewith (other
          than any such transfer taxes or similar governmental charge payable
          upon exchange or transfer pursuant to Sections 2.10 and 3.06 hereof).

                 (iii)  The Registrar shall not be required to register the
          transfer of or exchange any Senior Secured Note selected for
          redemption in whole or in part, except the unredeemed portion of any
          Senior Secured Note being redeemed in part.

                 (iv)   All Global Notes and Definitive Notes issued upon any
          registration of transfer or exchange of Global Notes or Definitive
          Notes shall be the valid obligations of the Issuers, evidencing the
          same debt, and entitled to the same benefits under this Indenture, as
          the Global Notes or Definitive Notes surrendered upon such
          registration of transfer or exchange.

                 (v)    The Issuers shall not be required (A) to issue, to
          register the transfer of, or to exchange any Senior Secured Notes
          during a period beginning at the opening of business fifteen (15) days
          before the day of any selection of Senior Secured Notes for redemption
          under Section 3.02 hereof and ending at the close of business on the
          day of selection, (B) to register the transfer of or to exchange any
          Senior Secured Note so selected for redemption in whole or in part,
          except the unredeemed portion of any Senior Secured Note being
          redeemed in part or (C) to register the transfer of or to exchange a
          Senior Secured Note between a record date and the next succeeding
          Interest Payment Date.

                 (vi)   Prior to due presentment for the registration of a
          transfer of any Note, the Trustee, any Agent and the Issuers may deem
          and treat the Person in whose name any Note is registered as the
          absolute owner of such Note for the purpose of receiving payment of
          principal of and interest on such Senior Secured Notes and for all
          other purposes, and none of the Trustee, any Agent or the Issuers
          shall be affected by notice to the contrary.

                 (vii)  The Trustee shall authenticate Global Notes and
          Definitive Notes in accordance with the provisions of Section 2.02
          hereof.

                 (viii) All certifications, certificates and Opinions of Counsel
          required to be submitted to the Registrar pursuant to this Section
          2.06 to effect a registration of transfer or exchange may be submitted
          by facsimile.

          Section 2.07. Replacement Senior Secured Notes. If any mutilated
Senior Secured Note is surrendered to the Trustee or the Issuers and the Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Senior Secured Note, the Issuers shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Senior Secured Note if
the Trustee's requirements are met. If required by the Trustee, Registrar or the
Issuers, an indemnity must be supplied by the Holder that is sufficient in the
judgment of the Trustee, Registrar and the Issuers to

                                       54
<PAGE>

protect the Issuers, the Trustee, any Agent and any authenticating agent from
any loss that any of them may suffer if a Senior Secured Note is replaced. The
Issuers and the Trustee may charge the Holder for their respective expenses in
replacing a Senior Secured Note.

          Every replacement Senior Secured Note is an additional obligation of
the Issuers and shall be entitled to all of the benefits of this Indenture
equally and proportionately with all other Senior Secured Notes duly issued
hereunder.

         SECTION 2.08. Outstanding Senior Secured Notes. The Senior Secured
Notes outstanding at any time are all the Senior Secured Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Senior Secured Note does not cease to be outstanding because either Issuer or an
Affiliate of the Issuers holds the Senior Secured Note; however, Senior Secured
Notes held by either Issuer or an Affiliate of the Issuers shall not be deemed
to be outstanding for purposes of Section 3.07(b) hereof.

          If a Senior Secured Note is replaced pursuant to Section 2.07 hereof,
it ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Senior Secured Note is held by a bona fide purchaser.

          If the principal amount of any Senior Secured Note is considered paid
under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

          If the Paying Agent (other than one of the Issuers, or an Affiliate of
the Issuers) holds, on a redemption date or maturity date, money sufficient to
pay Senior Secured Notes payable on that date, then on and after that date such
Senior Secured Notes shall be deemed to be no longer outstanding and shall cease
to accrue interest.

          In the event the Senior Secured Notes are issued in book-entry form
with the Depositary Agent: (i) the Trustee may deal with the Depositary Agent as
the authorized representative of the Holders; (ii) the rights of the Holders
shall be exercised only through the Depositary Agent and shall be limited to
those established by law and agreement between the Holders and the Depositary
Agent and/or direct participants of the Depositary Agent; (iii) the Depositary
Agent will make book-entry transfers among the direct participants of the
Depositary Agent and will receive and transmit distributions of principal and
interest on the Senior Secured Notes to such direct participants; and (iv) the
direct participants of the Depositary Agent shall have no rights under this
Indenture under or with respect to any of the Senior Secured Notes held on their
behalf by the Depositary Agent, and the Depositary Agent may be treated by the

                                       55
<PAGE>

Trustee and its agents, employees, officers and directors as the absolute owner
of the Senior Secured Notes for all purposes whatsoever.

          Section 2.09. Treasury Notes. In determining whether the Holders of
the required principal amount of Senior Secured Notes have concurred in any
direction, waiver or consent, Senior Secured Notes owned by either Issuer, or by
any Affiliate of the Issuers shall be considered as though not outstanding,
except that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Senior
Secured Notes that a Responsible Trust Officer of the Trustee actually knows are
so owned shall be so disregarded.

          Section 2.10. Temporary Senior Secured Notes. Until certificates
representing Senior Secured Notes are ready for delivery, the Issuers may
prepare and the Trustee, upon receipt of an Authentication Order, shall
authenticate temporary Senior Secured Notes. Temporary Notes shall be
substantially in the form of certificated Senior Secured Notes but may have
variations that the Issuers considers appropriate for temporary Senior Secured
Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable
delay, the Issuers shall prepare and the Trustee shall authenticate definitive
Senior Secured Notes in exchange for temporary Senior Secured Notes.

          Holders of temporary Senior Secured Notes shall be entitled to all of
the benefits of this Indenture.

          Section 2.11. Cancellation. The Issuers at any time may deliver Senior
Secured Notes to the Trustee for cancellation. The Registrar and Paying Agent
shall forward to the Trustee any Senior Secured Notes surrendered to them for
registration of transfer, exchange or payment. The Trustee and no one else shall
cancel all Senior Secured Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and shall destroy canceled Senior
Secured Notes (subject to the record retention requirement of the Exchange Act).
Certification of the destruction of all canceled Senior Secured Notes shall be
delivered to the Issuers. The Issuers may not issue new Senior Secured Notes to
replace Senior Secured Notes that they have paid or that have been delivered to
the Trustee for cancellation.

          Section 2.12. Defaulted Interest. If the Issuers default in a payment
of interest on the Senior Secured Notes, it shall pay the defaulted interest in
any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date, in
each case at the rate provided in the Senior Secured Notes and in Section 4.01
hereof. The Issuers shall notify the Trustee in writing of the amount of
defaulted interest proposed to be paid on each Senior Secured Note and the date
of the proposed payment. The Issuers shall fix or cause to be fixed each such
special record date and payment date, provided that no

                                       56
<PAGE>

such special record date shall be less than ten (10) days prior to the related
payment date for such defaulted interest. At least fifteen (15) days before the
special record date, the Issuers (or, upon the written request of the Issuers,
the Trustee in the name and at the expense of the Issuers) shall mail or cause
to be mailed to Holders a notice that states the special record date, the
related payment date and the amount of such interest to be paid.

          Section 2.13. The Collateral Agent. The Issuers and the Trustee (on
behalf of itself, and the Holders of the Senior Secured Notes) on the terms and
conditions specified herein and the Collateral Documents hereby irrevocably
appoint and authorize U.S. Bank Trust National Association, to act as the
Collateral Agent hereunder and under the Collateral Documents to which the
Collateral Agent is or becomes a party, with such powers, rights and obligations
as are expressly delegated to the Collateral Agent by the terms of this
Indenture and by the Collateral Documents.

                                   ARTICLE 3

                           REDEMPTION AND PREPAYMENT

          Section 3.01. Notices to Trustee. If the Issuers elect to redeem the
Senior Secured Notes pursuant to the optional redemption provisions of Section
3.07 hereof, they shall furnish to the Trustee, at least thirty (30) days but
not more than sixty (60) days before a redemption date, an Officers' Certificate
setting forth (i) the clause of this Indenture pursuant to which the redemption
shall occur, (ii) the redemption date, (iii) the principal amount of the Senior
Secured Notes to be redeemed and (iv) the redemption price.

          Section 3.02. Selection of Senior Secured Notes to Be Redeemed. If
less than all of the Senior Secured Notes are to be redeemed or purchased in an
offer to purchase at any time, the Trustee shall select the Senior Secured Notes
to be redeemed or purchased among the Holders of the Senior Secured Notes in
compliance with the requirements of the principle national securities exchange,
if any, on which the Senior Secured Notes are listed or, if the Senior Secured
Notes are not listed, on a pro rata basis, by lot or in accordance with any
other method the Trustee considers fair and appropriate; provided that no Senior
Secured Note less than $1,000 shall be redeemed in part. In the event of partial
redemption by lot, the particular Senior Secured Notes to be redeemed shall be
selected, unless otherwise provided herein, not less than thirty (30) nor more
than sixty (60) days prior to the redemption date by the Trustee from the
outstanding Senior Secured Notes not previously called for redemption.

                                       57
<PAGE>

          The Trustee shall promptly notify the Issuers in writing of the Senior
Secured Notes selected for redemption and, in the case of any Senior Secured
Note selected for partial redemption, the principal amount thereof to be
redeemed. Senior Secured Notes and portions of Senior Secured Notes selected
shall be in denominations of $100,000 and integral multiples of $1,000 in excess
thereof; except that if all of the Senior Secured Notes of a Holder are to be
redeemed, the entire outstanding amount of Senior Secured Notes held by such
Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided
in the preceding sentence, provisions of this Indenture that apply to Senior
Secured Notes called for redemption also apply to portions of Senior Secured
Notes called for redemption.

          Section 3.03. Notice of Redemption. At least thirty (30) days but not
more than sixty (60) days before a redemption date, the Issuers shall mail or
cause to be mailed, by first class mail, a notice of redemption to each Holder
whose Senior Secured Notes are to be redeemed at its registered address.

          The notice shall identify the Senior Secured Notes to be redeemed and
shall state:

          (a)  the redemption date;

          (b)  the redemption price;

          (c)  if any Senior Secured Note is being redeemed in part, the portion
of the principal amount of such Senior Secured Note to be redeemed and that,
after the redemption date upon surrender of such Senior Secured Note, a new
Senior Secured Note or Notes in principal amount equal to the unredeemed portion
shall be issued upon cancellation of the original Senior Secured Note;

          (d)  the name and address of the Paying Agent;

          (e)  that Senior Secured Notes called for redemption must be
surrendered to the Paying Agent to collect the redemption price;

          (f)  that, unless the Issuers default in making such redemption
payment, interest on Senior Secured Notes called for redemption ceases to accrue
on and after the Redemption Date;

          (g)  the paragraph of the Senior Secured Notes and/or Section of this
Indenture pursuant to which the Senior Secured Notes called for redemption are
being redeemed; and

                                       58
<PAGE>

          (h)  that no representation is made as to the correctness or accuracy
of the CUSIP number, if any, listed in such notice or printed on the Senior
Secured Notes.

          At the Issuers' request, the Trustee shall give the notice of
redemption in the Issuers' name and at their expense; provided, however, that
the Issuers shall have delivered to the Trustee, at least forty-five (45) days
prior to the redemption date, an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such
notice as provided in the preceding paragraph.

          Section 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed in accordance with Section 3.03 hereof, Senior Secured
Notes called for redemption become irrevocably due and payable on the Redemption
Date at the redemption price. A notice of redemption may not be conditional.

          Section 3.05. Deposit of Redemption Price. One Business Day prior to
the Redemption Date, the Issuers shall deposit with the Trustee or with the
Paying Agent money sufficient to pay the redemption price of and accrued
interest on all Senior Secured Notes to be redeemed on that date. The Trustee or
the Paying Agent shall promptly return to the Issuers any money deposited with
the Trustee or the Paying Agent by the Issuers in excess of the amounts
necessary to pay the redemption price of, and accrued interest on, all Senior
Secured Notes to be redeemed.

          If the Issuers comply with the provisions of the preceding paragraph,
on and after the Redemption Date, interest shall cease to accrue on the Senior
Secured Notes or the portions of Senior Secured Notes called for redemption. If
a Senior Secured Note is redeemed on or after an interest record date but on or
prior to the related interest payment date, then any accrued and unpaid interest
shall be paid to the Person in whose name such Senior Secured Note was
registered at the close of business on such record date. If any Senior Secured
Note called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Issuers to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the Redemption Date until
such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in the Senior Secured
Notes and in Section 4.01 hereof.

          Section 3.06. Senior Secured Notes Redeemed in Part. Upon surrender of
a Senior Secured Note that is redeemed in part, the Issuers shall issue and,
upon the Issuers' written request, the Trustee shall authenticate for the Holder
at the expense of the Issuers a new Senior Secured Note equal in principal
amount to the unredeemed portion of the Senior Secured Note surrendered.

         Section 3.07. Optional Redemption. (a) The Senior Secured Notes will be
redeemable at the option of the Issuers at any time and from time to time, in
whole or in

                                       59
<PAGE>

part, upon not less than thirty (30) nor more than sixty (60) days notice to
each Holder of the Senior Secured Notes, at a redemption price equal to the
Make-Whole Price. "Make-Whole Price" means an amount equal to the greater of (i)
100% of the principal amount of such Senior Secured Note and (ii) as determined
by a Reference Treasury Dealer, the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to the date of
redemption on a semi-annual basis (assuming a 360-day year consisting of twelve
30-day months) at the Adjusted Treasury Rate, plus, in each case, accrued and
unpaid interest thereon to the Redemption Date. Unless the Issuers default in
payment of the redemption price, on and after the Redemption Date, interest will
cease to accrue on the Senior Secured Note or portions thereof called for
redemption.

          (b)  Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

          SECTION 3.08. Mandatory Redemption. The Senior Secured Notes will be
subject to mandatory redemption, in whole or in part, at a redemption price
equal to the principal amount thereof plus accrued and unpaid interest to the
Redemption Date, upon:

          (a)  the receipt of Loss Proceeds or Eminent Domain Proceeds by POA if
POA determines that (i) the Project cannot be rebuilt, repaired or restored to
permit operations on a commercially reasonable basis, or POA determines not to
rebuild, repair or restore the Project, in which case the amount of such Loss
Proceeds or Eminent Domain Proceeds shall be available for such redemption, or
(ii) only a portion of the Project is capable of being rebuilt, repaired or
restored, in which case, if excess proceeds exist after such rebuild, repair or
restoration, only the amount of such excess Loss Proceeds or Eminent Domain
Proceeds shall be made available for such redemption;

          (b)  the receipt by POA of proceeds in connection with a Title Event,
in which case the amount of such Title Event Proceeds shall be made available
for such redemption, subject to reduction by the costs expended in connection
with collecting proceeds upon the occurrence of such Title Event, and any
additional reasonable costs or expenses that the Issuers will be subject to as a
result of the Title Event; and

          (c)  the receipt by POA of payments arising from the occurrence of a
Contract Termination Event in which case the amount of all such payments shall
be made available for such redemption subject to reduction in the case of a
Contract Termination Event relating to the Gas Purchase Agreement, by the costs
expended in connection with obtaining a replacement or substitute gas supply and
funding the Gas Reserve Account.

                                       60

     Other than as specifically provided in this Section 3.08, any purchase
pursuant to this Section 3.08 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

     Section 3.09. Repurchase at the Option of Holders Upon a Change of Control.
(a) Upon the occurrence of a Change of Control, each Holder of Senior Secured
Notes will have the right to require the Issuers to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Senior
Secured Notes, pursuant to the offer described in Sections (b) and (c) below
(the "Change of Control Offer"), at an offer price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the date of purchase (the "Change of
Control Payment").

     (b)  Within ten (10) days following any Change of Control, the Issuers will
mail a notice to each Holder describing the transaction or transactions that
constitute the Change of Control and offering to repurchase Senior Secured Notes
on the date specified in such notice, which date shall be no earlier than thirty
(30) days and no later than sixty (60) days from the date such notice is mailed
(the "Change of Control Payment Date"), pursuant to the procedures required by
this Indenture and described in such notice. The Issuers will comply with the
requirements of Rule l4e-1 under the Exchange Act and any other securities laws
and regulations thereunder to the extent such laws and regulations are
applicable in connection with the repurchase of the Senior Secured Notes as a
result of a Change of Control.

     (c)  On the Change of Control Payment Date, the Issuers will, to the
extent lawful:

           (i)   accept for payment all Senior Secured Notes or portions thereof
     properly tendered pursuant to the Change of Control Offer;

           (ii)  deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all Senior Secured Notes or portions thereof
     so tendered; and

           (iii) deliver or cause to be delivered to the Trustee the Senior
     Secured Notes so accepted together with an Officers' Certificate stating
     the aggregate principal amount of Senior Secured Notes or portions thereof
     being purchased by the Issuers. The Paying Agent will promptly mail to each
     Holder of Senior Secured Notes so tendered the Change of Control Payment
     for such Senior Secured Notes, and the Trustee will promptly authenticate
     and mail (or cause to be transferred by book entry) to each Holder a new
     Senior Secured Note equal in principal amount to any unpurchased portion of
     the Senior Secured Notes surrendered, if any; provided that each such new
     Senior

                                       61
<PAGE>

     Secured Note will be in a principal amount of $1,000 or an integral
     multiple thereof. The Issuers will publicly announce the results of the
     Change of Control Offer on or as soon as practicable after the Change of
     Control Payment Date.

     (d)  The Change of Control provisions described above in (a), (b) and (c)
of this Section 3.09 will be applicable whether or not any other provisions of
this Indenture are applicable to any Change of Control.

     (e)  Except as provided in this Section 3.09 with respect to a Change of
Control, nothing in this Indenture shall permit the Holders of the Senior
Secured Notes to require that the Issuers repurchase or redeem the Senior
Secured Notes in the event of a takeover, recapitalization or similar
transaction.

    (f)   Notwithstanding anything in (a), (b) or (c) of Section this 3.09, the
Issuers will not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Indenture applicable to a Change of Control Offer made by the Issuers and
purchases all Senior Secured Notes validly tendered and not withdrawn under such
Change of Control Offer.

and interest on the Senior Secured Notes on the dates and in the manner provided
in the Senior Secured Notes. Principal, premium, if any, and interest shall be
considered paid on the date due if the Paying Agent, if other than one of the
Issuers or an Affiliate thereof, holds as of 10:00 a.m. Eastern Time on the due
date money deposited by the Issuers in immediately available funds and
designated for and sufficient to pay all principal, premium, if any, and
interest then due.

     The Issuers shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Senior
Secured Notes to the extent lawful; it shall pay interest (including post-
petition interest in any proceeding under any Bankruptcy Law) on overdue

same rate to the extent lawful.

     Section 4.02. Partnership Existence. Each Issuer shall do or cause to be
done all things necessary to preserve and keep in full force and effect (i) its

may be amended from time to time) or its corporate existence, in accordance with
its certificate of incorporation (as the same may be amended from time to time),
as applicable, and (ii) the rights (charter and statutory), licenses and
franchises of such Issuer; provided, however, that neither Issuer shall be
required to preserve any such right, license or franchise, if the management
committee of such Issuer determines that the preservation thereof is no longer
desirable in the conduct of the business of such Issuer, and that the loss
thereof is not adverse in any material respect to the Holders of the Senior
Secured Notes.

     Section 4.03. Maintenance of Office or Agency. The Issuers shall maintain
in the Borough of Manhattan, the City of New York, an office or agency (which
may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-

transfer or for exchange and where notices and demands to or upon the Issuers in
respect of the Senior Secured Notes and this Indenture may be served. The
Issuers shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Issuers
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

     The Issuers may also from time to time designate one or more other offices
or agencies where the Senior Secured Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided,

                                       63
<PAGE>

however, that no such designation or rescission shall in any manner relieve the
Issuers of their obligations to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Issuers shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

one such office or agency of the Issuers in accordance with Section 2.03.

     Section 4.04. Reports, Budget. (a) Whether or not required by the rules and
regulations of the SEC, so long as any Senior Secured Notes are outstanding, the

the Issuers were required to file such forms, including a "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and,
with respect to the annual information only, a report thereon by the certified

     (c)  POA shall, no less than ninety (90) days in advance of the beginning
of each fiscal year adopt a draft Operating Budget of anticipated revenues, debt
service, proposed partnership distributions, maintenance, repair and operation
expenses (including reasonable allowance for contingencies), major maintenance
reserves and all other anticipated Operation and Maintenance Costs for the
ensuing fiscal year. Copies of the draft annual Operating Budget for each year
of operation shall be promptly furnished to the Independent Engineer for its
review and approval, which shall not be unreasonably withheld or delayed. POA
shall incorporate the Independent Engineer's reasonable suggestions (but only if
such suggestions are delivered to POA at least sixty (60) days in advance of
such fiscal year) into a final Operating Budget, which shall be prepared no less
than forty-five (45) days in advance of each fiscal year. The Operation and
Maintenance Costs in each such Operating Budget which are subject to escalation
limitations in the Project Documents shall not, absent extraordinary
circumstances, be increased by more than the amounts provided in such Project
Documents. POA will

                                       64
<PAGE>

operate and maintain the Project, or cause the Project to be operated and
maintained, in accordance with the requirements of such Operating Budget and the
Depositary Agreement; provided that the Operating Budget may be further amended
with the Independent Engineer's consent, which will not be unreasonably withheld
or delayed, to account for contingencies which could not reasonably have been
expected and in such event POA shall operate and maintain the Project, or cause
the Project to be operated and maintained, in accordance with the requirements
of the Depositary Agreement as applicable to the Operating Budget as so amended;
provided, further, that POA may make emergency repairs costing in excess of
amounts budgeted therefor if POA gives the Trustee, the Collateral Agent and the
Independent Engineer notice thereof promptly thereafter.

    Section 4.05. Compliance and Estoppel Certificates. (a) The Issuers shall
deliver to the Trustee and to each Rating Agency, within ninety (90) days after
the end of each fiscal year, an Officers' Certificate stating that a review of
the activities of the Issuers during the preceding fiscal year has been made
under the supervision of the signing Officer with a view to determining whether
the Issuers have kept, observed, performed and fulfilled their obligations under
this Indenture and the other Financing Documents, and further stating that to
the best of his or her knowledge the Issuers have kept, observed, performed and
fulfilled each and every covenant contained in this Indenture and the other
Financing Documents and are not in default in the performance or observance of
any of the terms, provisions and conditions of this Indenture and the other
Financing Documents (or, if a Default or Event of Default shall have occurred,
describing all such Defaults or Events of Default of which he or she may have
knowledge and what action the Issuers are taking or propose to take with respect
thereto) and that to the best of his or her knowledge no event has occurred and
remains in existence by reason of which payments on account of the principal of
or interest, if any, on the Senior Secured Notes is prohibited or if such event
has occurred, a description of the event and what action the Issuers are taking
or propose to take with respect thereto.

     (b)  So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.05(a) above shall be accompanied by a
written statement of the Issuers' independent public accountants (who shall be a
firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Issuers have violated
any provisions of Article 4 hereof or, if any such violation has occurred,
specifying the nature and period of existence thereof, it being understood that
such accountants shall not be liable directly or indirectly to any Person for
any failure to obtain knowledge of any such violation.

                                       65

     (c)  The Issuers shall, so long as any of the Senior Secured Notes are
outstanding, deliver to the Trustee, forthwith upon any Responsible Officer
becoming aware of any Default or Event of Default, an Officers' Certificate
specifying such Default or Event of Default and what action the Issuers are
taking or propose to take with respect thereto.

     (d)  The Issuers shall, so long as any of the Senior Secured Notes are
outstanding, deliver to the Trustee and the Collateral Agent, within five (5)
Business Days after receipt of a written request therefor from the Trustee or

Clerk's office, if requested by the Trustee or the Collateral Agent) specifying
(A) the aggregate unpaid principal amount of the Senior Secured Notes
outstanding, (B) the date to which interest payments due pursuant to the Senior
Secured Notes have been paid, (C) whether or not any Default or Event of Default

reasonably requested by, and reasonably satisfactory to, the Trustee and the
Collateral Agent that the Issuers have complied with their obligations under
this Indenture and the other Financing Documents.

     (e)  The Trustee or the Collateral Agent shall, so long as any Senior
Secured Notes are outstanding, deliver to the Issuers, promptly (but in any
event within twenty (20) Business Days) after receipt of a written request
therefor from the Issuers, a certificate by the Trustee or the Collateral Agent,
as the case may be, specifying to the knowledge of the Trustee or the Collateral
Agent, as the case may be (i) the aggregate unpaid principal amount of the
Senior Secured Notes outstanding, (ii) the date to which interest payments due
pursuant to the Senior Secured Notes have been paid, and (iii) whether or not
any Default or Event of Default has occurred or is continuing.

     Section 4.06. Taxes. The Issuers shall pay prior to delinquency, all
Impositions except such as are contested in good faith and by appropriate
proceedings, for which adequate reserves have been established in accordance
with generally accepted accounting principles, and which would not have a
Material Adverse Effect.

     Section 4.07. Stay, Extension and Usury Laws. The Issuers shall not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay, extension or usury law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the performance of
this Indenture; and the Issuers hereby expressly waive all benefit or advantage
of any such law, and covenants that they shall not, by resort to any such law,
hinder, delay or impede the execution of any power herein granted to the
Trustee, but shall suffer and permit the execution of every such power as though
no such law has been enacted.

to be maintained on its behalf in effect at all times the types of insurance
required by the following provisions together with any other types of insurance
required hereunder, with insurance companies rated "A" or better (and a minimum
size rating of XIII) by Best's Insurance Guide and Key Ratings (or an equivalent
rating by another nationally recognized insurance rating agency of similar

or Lloyd's Companies, the following insurance coverages until all obligations of
the Issuers pursuant to this Indenture and the other Financing Documents have

               Deductibles and exclusions shall be consistent with normal
     industry practice for similar operations for property and facilities
     similar in nature, use and location of the Project and the Steam Plant. The
     comprehensive or commercial general liability policy shall also include a
     cross-liability and severability of interest clause. Work performed by
     others for the Issuers shall not commence until a certificate of insurance

     naming the Issuers as insured or additional insured and the Collateral
     Agent as additional insured;

         (ii)  Automobile liability insurance, including coverage for owned,

     and other states' endorsement and USL&H Act coverage (if such exposure
     exists), covering loss resulting from injury, sickness, disability or death
     of the employees of POA or its contractors or subcontractors performing
     work on or with respect to the Premises and the Project; and POA shall

     the foregoing insurance with respect to their employees performing work on
     or with respect to the Premises and the Project or the Steam Plant;

         (iv)  POA shall maintain "all risk" property insurance coverage in the

     first party hazardous material cleanup for the Premises (provided however
     that such hazardous material clean up shall be subject to an annual

     respect to the Project, boiler and machinery coverage on a "comprehensive"
     basis including breakdown and repair with limits not-loss than full
     replacement cost of the insured objects. POA shall also maintain or cause
     to be maintained off-site coverage with a per occurrence limit sufficient
     to cover replacement of all off-site equipment, and transit coverage
     (including ocean cargo where ocean transit will be required) with a per
     occurrence limit sufficient to cover the full insurable value of any item
     in transit. POA shall also maintain or cause to be maintained with respect
     to the Project business interruption insurance on both property and boiler
     policies, including contingent business interruption insurance with respect
     to the Niagara Mohawk substation, in an amount equal to satisfy policy
     coinsurance conditions, but not less than the sum of fifteen (15) months
     debt service, continuing expenses and profits. If profits are insured, the
     business interruption policy may include an endorsement allowing such
     profits to be paid to POA; other proceeds shall be paid to the Collateral
     Agent. POA shall also maintain or cause to be maintained, expediting or
     extra expense coverage in an amount not less than $3,000,000. With respect

<PAGE>

     greater than thirty (30) days. The policy/policies shall include increased
     cost of construction coverage, debris removable, and building ordinance
     coverage to pay for loss of "undamaged" property which may be required to
     be replaced due to enforcement of local, state, or federal ordinances.

         (v)    Fidelity and employee dishonesty coverage shall be secured for
     the Project, protecting against loss from employees of POA and the
     Partners, the Operator, the Asset Manager and any other contractors or
     subcontractors on or with respect to the Premises and the Project, in an
     amount of $1,000,000 and a deductible of not greater than $25,000.

         (vi)   Umbrella Excess Liability Insurance on or with respect to the
     Premises and the Project of not less than $50,000,000. Such coverages shall
     be on a per occurrence basis and over and above coverage provided by the
     policies described in clauses (i), (ii), and (iii) above. The umbrella
     and/or excess policies shall not contain endorsements which restrict
     coverages as set forth in clauses (i), (ii), and (iii) above, and which are
     provided in the underlying policies, with the exception of "Failure to
     Supply", which may be sublimited to $25,000,000.

         (vii)  Liability insurance in the amount of $25,000,000 for hired or
     non-owned aircraft and, in the event any exposure to the Project or the
     Issuers exists for owned aircraft, liability insurance in the amount of
     $25,000,000 for such owned aircraft.

         (viii) Such other insurance (as to risks covered, policy amounts,
     policy provisions or otherwise) as, consistent with normal industry
     practice for similar operations, are from time to time insured against for
     property and facilities similar in nature, use and location to the Project
     and the Steam Plant which the Required Holders, after consultation with the
     Insurance Consultant, may reasonably require.

     All insurance coverage shall be on a "no coinsurance basis".

     For purposes of this Section 4.09, the term "Project" shall include all
property which may not otherwise be within the definition of "Project" but which
is within the care, custody or control of POA or its agents, with the exception
of contractor and subcontractor tools and equipment.

     (b) All policies except the worker's compensation policies described
in Section 4.09(a)(iii) and the property insurance policies described in Section
4.09(a)(iv), shall name the Collateral Agent, the Trustee and the other Secured
Parties as additional insureds. The property insurance described in Section
4.09(a)(iv) and any other

                                       69
<PAGE>

property insurance covering loss or damage to the Project shall name the
Collateral Agent as mortgagee and loss payee and shall provide that any payment
thereunder for any loss or damage with respect to the Project shall be made to
the Collateral Agent, except that such policies may provide that any payments of
less than $250,000 made in respect of any single casualty or other occurrence
(not to exceed $500,000 in any year with respect to multiple casualties or
occurrences) may be paid solely to POA, unless Trustee shall have notified the
respective insurer that an Event of Default has occurred thereunder and shall be
continuing. Upon payment and satisfaction of all of the Issuers' obligations
under and termination of the Financing Documents, the Trustee and the Collateral
Agent, at the request and expense of POA, will instruct the insurers to name
POA, or such successor credit provider or other Person as POA shall specify, as
loss payee. Each such policy shall expressly provide that all provisions
thereof, except the limits of liability (which shall be applicable to all
insureds as a group) and liability for premiums (which shall be solely a
liability of POA) shall operate in the same manner as if there were a separate
policy covering each such insured. Each such policy shall waive subrogation
against any of the Secured Parties and POA and shall waive any right of the
insurers to any setoff or counterclaim or any other deduction, whether by
attachment or otherwise, in respect of any liability of POA or the Secured
Parties. Each such policy shall provide that if any premium or installment is
not paid when due, or if such insurance is to be canceled, terminated or
materially changed for any reason whatsoever, the insurers (or their
representatives) will promptly notify POA and the Trustee and the Collateral
Agent, and any such cancellation, termination or change shall not be effective
until thirty (30) days after receipt of such notice by the Trustee and the
Collateral Agent, and that appropriate certification shall be made to POA by
each insurer with respect thereto.

     (c)  In the event that POA fails to respond in a timely and appropriate
manner (as reasonably determined by the Collateral Agent) to take any steps
necessary or reasonably requested by the Collateral Agent to collect from any
insurers for any loss covered by any insurance required to be maintained by this
Section 4.09, the Collateral Agent shall have the right to make all proofs of
loss, adjust all claims and/or receive all or any part of the proceeds of the
foregoing insurance policies, either in its own name or the name of POA;
provided, however, that POA shall, upon the Collateral Agent's request and at
POA's own cost and expense, make all proofs of loss and take all other steps
necessary or reasonably requested by the Collateral Agent to collect from
insurers for any loss covered by any insurance required to be obtained by this
Section 4.09.

     (d)  On or before March 1 of each year, commencing with March 1, 2000, POA
shall furnish to the Trustee and the Collateral Agent, an Officers' Certificate,
showing the insurance then maintained by or on behalf of POA pursuant to this
Section 4.09 and stating that such insurance complies in all material aspects
with the terms hereof, together with evidence of payment of the premiums
thereon. In the event that at

                                       70
<PAGE>

any time the insurance as herein provided shall be reduced or cease to be
maintained, then (without limiting the rights of the Trustee hereunder in
respect of the Event of Default which arises as a result of such failure) the
Trustee or the Collateral Agent may at its option maintain the insurance
required hereby and, in such event, POA shall reimburse the Trustee or the
Collateral Agent, as the case may be, upon demand for the cost thereof together
with interest thereon at a rate per annum equal to the Default Rate, but in no
event shall the rate of interest exceed the maximum rate permitted by law. On or
before December 15, 1999, POA shall furnish to the Trustee and the Collateral
Agent all insurance appraisals of the replacement cost of the Project and the
Steam Plant prepared by a qualified independent appraiser; and, if such
appraisal shall show a replacement cost of the Project and the Steam Plant in
excess of the current amount of the property insurance described in Section
4.09(a)(iv) then applicable with respect to the Project and the Steam Plant, an
Officers' Certificate showing that the amount of such property insurance has
been increased to at least the amount of the replacement cost set forth in such
appraisal. On or before March 1 or such even numbered year commencing with March
1, 2002, POA shall furnish to the Trustee and the Collateral Agent insurance
appraisals of the replacement cost of the Project prepared by a qualified
independent appraiser; and, if such appraisals shall show a replacement cost of
the Project in excess of the current amount of the property insurance described
in Section 4.09(a)(iv) then applicable with respect to the Project an Officers'
Certificate showing that the amount of such property insurance has been
increased to the amount of the replacement cost set forth in such appraisal.

          (e)  In the event any insurance (including the limits or deductibles
thereof) hereby required to be maintained, above shall not be available at
commercially reasonable rates and on commercially reasonable terms in the
commercial insurance market, then such requirement shall be deemed waived, but
only to the extent and for so long as, the maintenance thereof is not so
available; provided, however, that (i) POA shall first request any such waiver
in writing, which request shall be accompanied by written reports prepared by
two independent insurance advisers of recognized national standing certifying
that such insurance is not reasonably available and commercially feasible in the
commercial insurance market for electric generating plants of similar type and
capacity (and, in any case where the required amount is not so available,
certifying as to the maximum amount which is so available) and explaining in
detail the basis for such conclusions; (ii) at any time after the granting of
any such waiver, the Trustee or the Collateral Agent may request, and POA shall
furnish to the Trustee or the Collateral Agent within fifteen (15) days after
such request, supplemental reports from such insurance advisers updating their
prior reports and reaffirming such conclusion; and (iii) any such waiver shall
be effective only so long as such insurance shall not be available and
commercially feasible in the commercial insurance market, it being understood
that the failure of POA to timely furnish any such supplemental report shall be
conclusive evidence that such waiver is no longer effective because such
condition no longer exists, but that such failure is not the only way to
establish such non-

                                       71
<PAGE>

existence. The failure at any time to satisfy the conditions to any waiver of an
insurance requirement set forth in the proviso to the preceding sentence shall
not impair or be construed as a relinquishment of POA's ability to obtain a
waiver of an insurance requirement pursuant to the preceding sentence at any
other time upon satisfaction of such conditions.

          Section 4.17. Operation of the Project. (a) POA will operate the
Project at all times except to the extent prevented by scheduled and unscheduled
maintenance in a manner consistent with prudent industry practice for similar
operations and, in any event, in a manner so as to guarantee that POA's
obligations to provide steam to the University under the Steam Contract and to
make payments to Niagara Mohawk under the Indexed Swap Agreement shall be met,
and as consistent with prudent industry practice, and in compliance with the
Project Documents so as to assure, to the extent reasonably possible, the
maximum generation of net revenue for the Project consistent with the Project
Documents.

               (b)  (i) POA shall renew, extend or replace the O&M Agreement so
          that its remains in full force and effect at all times and shall
          replace or consent to the replacement of the Operator if the Operator
          is not operating the Project and the Steam Plant in accordance, in all
          material respects, with the provisions of any of the Financing
          Documents, the O&M Agreement, and the other Material Project
          Documents, upon receipt of notice from Trustee to the effect that, in
          the opinion of the Required Holders or the Independent Engineer, the
          Operator has failed to perform any material obligations which are or
          may be performed on POA's behalf by the Operator or has failed to
          perform its obligations under the O&M Agreement; provided however,
          that the Operator may have thirty (30) days from POA's receipt of
          notice to cure said failure (or to establish to the satisfaction of
          the Required Holders that a failure does not exist); provided,
          further, that if such failure cannot be corrected within such 30-day
          period, the Required Holders will not unreasonably withhold their
          consent to an extension of such time if corrective action is promptly
          instituted by the Operator within the 30-day period and thereafter
          diligently pursued until the failure is corrected and such extension
          shall not in the judgment of the Required Holders have a material
          adverse effect on the Holders' interests in the Project and the
          Collateral. Notwithstanding the above, POA will have no obligation to
          terminate the O&M Agreement if such termination would constitute a
          breach under the O&M Agreement.

               (ii)  POA shall not exercise its right under Section of 6.01(b)
          the O&M Agreement as in effect on the Closing Date to terminate the
          obligation of the Operator to perform major maintenance on the gas
          turbine packages in return for the payment of the fired-hour fee
          without the consent of the Required Holders.

               (iii) POA shall continue its membership in the lease engine
          support program under which General Electric Company will deliver and
          install substitute leased turbine equipment if either of the Project's
          gas turbines inoperative and need to be repaired or replaced; provided
          that if such lease

                                       74
<PAGE>

         engine support program (or a substantially similar program) shall not
         be available at commercially reasonable rates and on commercially
         reasonable terms, then such requirement shall be deemed waived, but
         only to the extent and for so long as, such lease engine support
         program (or a substantially similar program) is not so available;
         provided, further, that (i) POA shall first request any such waiver in
         writing, which request shall be accompanied by a written report
         prepared by the Independent Engineer certifying that such lease engine
         support program (or a substantially similar program) is not reasonably
         available and commercially feasible and explaining in detail the basis
         for such conclusions; (ii) at any time after the granting of any such
         waiver, the Trustee may request, and POA shall furnish to the Trustee
         within fifteen (15) days after such request, supplemental reports from
         the Independent Engineer updating its prior reports and reaffirming
         such conclusion; and (iii) any such waiver shall be effective only so
         long as such lease engine support program (or a substantially similar
         program) shall not be available and commercially feasible, it being
         understood that the failure of POA to timely furnish any such
         supplemental report shall be conclusive evidence that such waiver is no
         longer effective because such condition no longer exists, but that such
         failure is not the only way to establish such non-existence. The
         failure at any time to satisfy the conditions to any waiver of this
         requirement set forth in the proviso to the preceding sentence shall
         not impair or be construed as a relinquishment of POA's ability to
         obtain a waiver of the requirement that it participate in the lease
         engine support program pursuant to the preceding sentence at any other
         time upon satisfaction of such conditions.

         (c) POA shall renew, extend or replace the Asset Management Agreement
so that it remains in full force and effect at all times and shall replace or
consent to the replacement of the Asset Manager if the Asset Manager is not
managing the Project and the Steam Plant in accordance, in all material
respects, with the provisions of any of the Financing Documents, the Asset
Management Agreement and the other Material Project Documents, upon receipt of
notice from Trustee to the effect that, in the opinion of the Required Holders
or the Independent Engineer, the Asset Manager has failed to perform any
material obligations which are or may be performed on POA's behalf by the Asset
Manager or has failed to perform its obligations under the Asset Management
Agreement; provided however, that the Asset Manager may have thirty (30) days
from POA's receipt of notice to cure said failure (or to establish to the
satisfaction of the Required Holders that a failure does not exist); provided
further, that if such failure cannot be corrected within such thirty (30) days,
the Required Holders will not unreasonably withhold their consent to an
extension of such time if corrective action is promptly instituted by the Asset
Manager within the 30-day period and thereafter diligently pursued until the
failure is corrected and such extension shall not in the judgment of the
Required Holders have a material adverse effect on the Holders' interests in the
Project and the Collateral. Notwithstanding the above, POA will have

                                       75
<PAGE>

no obligation to terminate the Asset Management Agreement if such termination
would constitute a breach under the Asset Management Agreement.

          Section 4.18. Prohibitions on Fundamental Changes. (a) Except for the
Merger, POA shall not enter into any transaction of merger or consolidation,
change its form of organization or its business, liquidate, wind-up or dissolve
itself or discontinue its business. POA shall not engage in any business other
than in connection with owning and operating the Project and the activities
incidental thereto, issuing the Senior Secured Notes, incurring Permitted
Indebtedness and performing its obligations under the Operative Documents. POA
shall not lease (as lessor) or sell, transfer, assign, hypothecate, pledge or
otherwise dispose of any of its property or assets, except for (i) sales of
obsolete, worn out or replaced property not used or useful in its business, in
each case for not less than fair market value, (ii) in the ordinary course of
business as contemplated by the Project Documents (it being understood that any
sales of natural gas must be made in accordance with Section 4.18(b)), (iii) the
sale of Permitted Investments, and (iv) sales of natural gas that are permitted
pursuant to subsection (b).

          (b) In order for a sale of natural gas to be permitted, it must
satisfy the following conditions:

         (1)  after giving effect to such sale of natural gas, the aggregate
              quantity of gas sold or consumed by the Project and the Steam
              Plant during any twelve month period shall not exceed the maximum
              displacement amount permitted to be drawn under the Gas Purchase
              Agreement during such period plus such additional amounts as would
              not cause the Gas Reserve Deficit to be greater than zero;

         (2)  such sale of natural gas must satisfy the requirements of the Gas
              Purchase Agreement and the other Project Documents and, after
              giving effect to such sale, POA shall continue to be entitled to
              draw and/or have secured supply and transportation rights to,
              natural gas sufficient for it to meet its obligations under the
              Steam Contract;

         (3)  the purchase price for such natural gas must be payable in U.S.
              dollars on a date certain and the purchaser must, in writing,
              agree to remit such purchase price directly to the Revenue Account
              and consent to the assignment by POA of its rights under the
              natural gas purchase agreement with such purchaser to the
              Collateral Agent;

         (4)  the purchaser of such natural gas must either itself have, or
              arrange for its obligations to POA to be secured by a letter of
              credit or guaranty issued by an entity that has outstanding
              unsubordinated unsecured long term debt that is rated Investment
              Grade, defined as "Baa3" and "BBB-" by Moody's and

                                       76
<PAGE>

              S&P, respectively, or if a rating agency from one or both of the
              foregoing rating agencies is not available a rating of at least
              "BBB-" by Dominion Bond Rating Service or B++ low by Canadian Bond
              Rating Service, or in the alternative, secure its payment
              obligations to POA by depositing cash or cash equivalents as
              collateral with the Collateral Agent in a manner sufficient, as
              established by an Opinion of Counsel, to create a perfected
              security interest therein in favor of POA and the Collateral Agent
              as POA's assignee; and

         (5)  POA shall not sell any natural gas which it is entitled to draw
              during any period when the Senior Secured Notes remain outstanding
              unless all of the following conditions are satisfied:

              (A) POA shall not sell any entitlement that it has to draw natural
                  gas during on-peak hours (as defined in the Indexed Swap
                  Agreement) between June 15 and September 15 of any year;

              (B) For any period for which POA does sell its entitlement to draw
                  natural gas, it will purchase the right (whether in a
                  financial transaction or transaction for physical delivery of
                  energy and associated capacity) to acquire an equivalent
                  amount of energy and associated capacity (on a Btu equivalent
                  basis assuming an unadjusted heat rate value equal to 10,000
                  Btu/kWh at the higher heating value in 2000, and as adjusted
                  for 0.5% annual degradation on a going forward basis) for a
                  purchase price that is less than or equal to the net proceeds
                  payable to POA from the sale of such natural gas;

              (C) The energy and associated capacity that POA has the right to
                  purchase must be deliverable or settle during the same period
                  during which the natural gas sold was to be drawn so that POA
                  could acquire and resell such energy and associated capacity
                  through the ISO/PE or settle the financial transaction in such
                  a way as to generate revenues sufficient to pay Niagara Mohawk
                  the floating rate payment payable by POA under the Indexed
                  Swap Agreement that corresponds to such period;

              (D) The payment terms with regard to the energy and associated
                  capacity that POA has the right to purchase for any period
                  must be such that the proceeds of sale from the natural gas
                  sold that corresponds to such period will be available to pay
                  when due the purchase price of, or settlement amount for, such
                  energy and associated capacity;

                                       77
<PAGE>

              (E) In the case of contracts for the delivery of energy and
                  associated capacity, the seller of such energy and associated
                  capacity to POA must agree to pay liquidated damages to POA in
                  the event that the seller fails to deliver any energy and
                  associated capacity acquired by POA in an amount at least
                  equal to the amount that POA would have received if such
                  energy and associated capacity was delivered and sold by POA
                  through the ISO/PE net of revenues (after costs of cover) POA
                  receives from any cover transaction in replacement of such
                  failed deliveries of energy and associated capacity;

              (F) The seller of such energy and associated capacity must agree
                  in writing to remit any liquidated damages or other payments
                  required to be made by it to POA directly to the Revenue
                  Account and consent to the assignment by POA of its rights
                  under the energy and associated capacity purchase agreement to
                  the Collateral Agent; and

              (G) The seller of such energy and associated capacity must either
                  itself have, or arrange for its obligations to POA to be
                  secured by a letter of credit or guaranty issued by an entity
                  that has, outstanding unsubordinated unsecured long term debt
                  that is rated investment grade by either Moody's or S&P or, in
                  the alternative, secure its payment obligations to POA by
                  depositing cash or cash equivalents as collateral with the
                  Collateral Agent in a manner sufficient, as established by an
                  Opinion of Counsel, to create a perfected security interest
                  therein in favor of POA and the Collateral Agent as POA's
                  assignee, such security to be in an amount adequate, in
                  accordance with then applicable industry standards, to protect
                  POA from risk of counterparty default.

          Section 4.19.  Separate Existence.  POA covenants and agrees:

          (a) to maintain its own deposit account or accounts to which none of

such costs;

          (d) that to the extent it contracts or does business with vendors or
service providers where the goods and services provided are partially for the
benefit of any of its partners or any of its Affiliates, the costs incurred in
so doing shall be fairly allocated to or among such entities for whose benefit
the goods or services are provided, and each such entity shall bear its fair
share of such costs;

          (e) that to the extent it and any of its partners or any of its
Affiliates have officers in the same location, there shall be a fair and
appropriate allocation of overhead costs among them, and each such entity shall
bear its fair share of such expenses; and

          (f) to conduct its affairs strictly in accordance with its Partnership
Agreement and the Project Orange Associates L.P. Partnership Management

4.18(b) and (iv) the Project Documents and the exercise of rights thereunder as

applicable laws, ordinances, rules, regulations, requirements, orders, decrees
and judgments of Governmental Authorities (including, Environmental Laws and
ERISA and the rules and regulations thereunder) (except (i) where the failure to
so comply would not have a Material Adverse Effect and would not in any manner
draw into question the validity of any Operative Document or (ii) where the
necessity of compliance therewith is contested in good faith by appropriate
proceedings and for which adequate reserves have been established in accordance
with generally accepted accounting principles) and will maintain all applicable
Permits (except where the failure to maintain such applicable Permits would not

Affiliates shall be deemed subject to, or not be exempt from, regulation under
the FPA or PUHCA or under any state laws or regulations respecting sales or the
financial or organizational regulation of electric utilities solely as a result
of holding the Senior Secured Notes.

                                       80
<PAGE>

          (a) failure to pay any principal, premium, if any, and interest or
other amounts owed on any Senior Secured Note when the same becomes due and
payable, whether by scheduled maturity or required prepayment or redemption or
by acceleration or otherwise, and such failure continues for five (5) days or
more following the due date for payment; or

          (b) any representation or warranty made by the Issuers or any other
Credit Party in this Indenture or in any other Financing Document or any
representation, warranty or statement in any certificate, financial statement or
other document furnished to the Trustee or any other Person by or on behalf of
either of the Issuers or any other Credit Party proves to have been untrue or
misleading in any material respect as of the time made, confirmed or furnished
and the fact, event or circumstance that gave rise to such inaccuracy has
resulted in, or could reasonably be expected to result in, a Material Adverse
Effect and that fact, event or circumstance continues uncured for thirty (30) or
more days from the date the POA receives notice thereof from the Trustee;
provided that, if such Issuer or other Credit Party commences and diligently
pursues efforts to cure such fact, event or circumstance within such 30-day
period and deliver written notice to the Trustee thereof, such Issuer or other
Credit Party may continue to effect such cure, and such misrepresentation shall
not be deemed an "Event of Default" for an additional sixty (60) days so long as
such Issuer or other Credit Party is diligently pursuing such cure; or

          (c) (i) either Issuer fails to pay any Imposition as and when due and
payable, and such failure continues for fifteen (15) days or more following the
date such payment becomes delinquent; or (ii) either Issuer fails to perform or
observe any covenant, agreement or provision binding upon it contained in this
Indenture or any of the other Financing Documents regarding maintenance of
existence or restrictions on Indebtedness, Liens, Restricted Payments,
Guarantees, Investments, Sale Lease-Back Transactions, Affiliate Transactions,
Project Documents, disposition of assets, operation of the Project, fundamental
changes, or nature of business and such failure continues uncured for thirty
(30) or more days from the date the Issuers receive notice thereof from the
Trustee; or if such Issuer fails to perform or observe any covenant, agreement
or provision binding upon it contained in any of the Project Documents and such
failure continues uncured for thirty (30) or more days from the date such Issuer
receives notice thereof from the Trustee (provided that the same does not
constitute an event of default under the relevant Project Document), or (iii) an
event that then gives any Person the right to terminate or materially adversely
affect any of POA's rights under the relevant Project Document; or (iv) if any
event of default by POA under any of the Project Documents, or any event arises
that in either case then gives any Person (other than POA) the right to
terminate or materially adversely affects any of POA's rights under any of the
Project Documents, shall occur and be continuing; or (v) any event that then
gives the University the right to foreclose under any University Collateral
Document; or (vi) the commencement and continuance of any action, suit or
proceeding

                                       81
<PAGE>

for the foreclosure, including foreclosure any power of sale, of any lien on or
security interest in any Collateral, including any such foreclosure under any
University Collateral Document; or

          (d) either Issuer or any other Credit Party fails to perform or
observe any covenant, agreement or provision binding upon it contained in this
Indenture or any of the other Financing Documents (other than those referred to
in clauses (a) through (c) inclusive above and (e) through (g) inclusive below)
and such failure continues uncured for thirty (30) or more days from the date
POA receives notice thereof from the Trustee of such failure; provided that if
such Issuer or other Credit Party commences and diligently pursues efforts to
cure such default within such 30-day period, such Issuer or other Credit Party
may continue to effect such cure of the default and such default will not be
deemed an "Event of Default" for an additional ninety (90) days so long as such
Issuer or other Credit Party is diligently pursuing such cure;

          (e) either Issuer:

                  (i) admits in writing its inability, or is generally unable,
         to pay its debts as the debts become due or makes a general assignment
         for the benefit of creditors; or

                 (ii) commences any case, proceeding or other action seeking
         reorganization, arrangement, adjustment, liquidation, dissolution or
         composition of it or its debts under any applicable liquidation,
         conservatorship, bankruptcy, moratorium, arrangement, adjustment,
         insolvency, reorganization or similar laws affecting the rights or
         remedies of creditors generally, as in effect from time to time
         (collectively, "Debtor Relief Law"); or

                (iii) in any involuntary case, proceeding or other action
         commenced against it which seeks to have an order for relief
         (injunctive or otherwise) entered against it, as debtor, or seeks
         reorganization, arrangement, adjustment, liquidation, dissolution or
         composition of it or its debts under any Debtor Relief Law, (A) fails
         to obtain a dismissal of such case, proceeding or other action within
         ninety (90) days of its commencement, or (B) converts the case from one
         chapter of the Bankruptcy Reform Act of 1978, as amended, to another
         chapter, or (C) is the subject of an order for relief, or

                 (iv) has a trustee, receiver, custodian or other official
         appointed for or take possession of all or any part of its property or
         has any court take jurisdiction of any of its property, which action
         remains undismissed for a period of ninety (90) days;

                                       82
<PAGE>

         (f) any Collateral Document or any material provision thereof ceases
to be in full force and effect or there is a Material Adverse Effect on the Lien
purported to be granted under any such Collateral Document such that it ceases
to be a valid and perfected Lien in favor of the Collateral Agent for the
benefit of the Secured Parties on the Collateral described therein with the
priority purported to be created thereby; provided, however, that POA shall have
ten (10) days after POA obtains actual knowledge thereof to cure any such
cessation, if curable, or to furnish to the Collateral Agent all documents or
instruments required to cure any such cessation, if curable; or

         (g) any event of default under any Permitted Indebtedness of either
Issuer which results in Permitted Indebtedness in excess of $2,500,000 becoming
due and payable prior to its stated maturity.

         Section 5.02.  Enforcement of Remedies.  (a) If one or more Events of
Default have occurred and are continuing, then:

               (i)  in the case of an Event of Default described in Section
         5.01(e), 9.13(k), 1.01(k) above, the entire principal amount of the
         Outstanding Notes, all interest accrued and unpaid thereon, and all
         premium and other amounts payable under the Senior Secured Notes, this
         Indenture, and the other Financing Documents if any, will automatically
         become due and payable without presentment, demand, protest or notice
         of any kind; or

               (ii) in the case of an Event of Default described in:

                    (A) Section 5.01(a), upon the written direction of the
               Holders of no less than 25% in aggregate principal amount of the
               Outstanding Notes, the Trustee will, by notice to the Issuers,
               declare the entire principal amount of the Outstanding Notes, all
               interest accrued and unpaid thereon, and all premium and other
               amounts payable under the Senior Secured Notes, this Indenture
               and the other Financing Documents, if any, to be due and payable,
               or

                    (B) Section 5.01(b), 9.13(k), 1.01(k), (c), (d), (f) or (g)
               upon the written direction of the Required Holders, the Trustee
               will, by notice to the Issuers, declare the entire principal
               amount of the Senior Secured Notes, all interest accrued and
               unpaid thereon, and all premium and other amounts payable under
               the Senior Secured Notes, this Indenture and the other Financing
               Documents, if any, to be due and payable.

         If an Event of Default occurs and is continuing and is actually known
to a Responsible Trust Officer, the Trustee will mail to each Holder notice of
the Event of

                                       83
<PAGE>

Default within thirty (30) days after the occurrence thereof. Except in the case
of an Event of Default in payment of principal of or interest on any Senior
Secured Note, the Trustee may withhold the notice to the Holders if the Trustee
in good faith determines that withholding the notice is in the interest of the
Holders.

         If an Event of Default relating to failure to pay amounts owed on the
Senior Secured Notes has occurred and is continuing, the Trustee may declare the
principal amount of the Outstanding Notes, all interest accrued and unpaid
thereon, and all premium and other amounts payable under the Senior Secured
Notes, this Indenture and other Financing Documents, if any, to be due and
payable notwithstanding the absence of direction from Holders of at least 25% in
aggregate principal amount of the Outstanding Notes directing the Trustee in
writing to accelerate the maturity of the Senior Secured Notes, unless Holders
of more than 75% in aggregate principal amount of the Outstanding Notes direct
the Trustee not to accelerate the maturity of such Senior Secured Notes, if in
the good faith exercise of its discretion the Trustee determines that such
action is necessary to protect the interests of the Holders.

         In addition, if one or more of the Events of Default referred to in
Section 5.02(a)(ii)(B) has occurred and is continuing, the Trustee may declare
the entire principal amount of the Outstanding Notes, all interest accrued and
unpaid thereon, and all premium and other amounts payable under the Senior
Secured Notes, this Indenture and the other Financing Documents, if any, to be
due and payable notwithstanding the absence of direction from the Required
Holders directing the Trustee to accelerate the maturity of the Senior Secured
Notes unless the Required Holders direct the Trustee in writing not to
accelerate the maturity of the Senior Secured Notes if in the good faith
exercise of its discretion the Trustee determines that such action is necessary
to protect the interests of the Holders.

         (b)  At any time after the principal of the Senior Secured Notes has
become due and payable upon a declared acceleration, and before any judgment or
decree for the payment of the money so due, or any portion thereof, has been
entered, the Holders of not less than a majority in aggregate principal amount
of the Outstanding Notes, by written notice to the Issuers and the Trustee,
shall rescind and annul such declaration and its consequences if:

              (i)  there has been paid to or deposited with the Trustee a
     sum sufficient to pay

                   (A) all overdue interest on the Senior Secured
                  Notes; and

                   (B) the principal of and premium, if any, on any Senior
              Secured Notes that have become due (including overdue principal)
              other than by such declaration of acceleration and interest
              thereon at

                                       84
<PAGE>

                  the respective rates provided in the Senior Secured Notes for
                  overdue principal; and

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the respective rates
                  provided in the Senior Secured Notes for overdue interest; and

                           (D) all sums paid or advanced by the Trustee and the
                  Collateral Agent and the reasonable compensation, expenses,
                  disbursements, and advances of the Trustee and the Collateral
                  Agent and their agents and counsel; and

                           (E) all Events of Default, other than the nonpayment
                  of the principal of the Senior Secured Notes that has become
                  due solely by such acceleration, have been cured or waived in
                  accordance with this Indenture.

          (c) If an Event of Default relating to failure to pay amounts owed on
the Senior Secured Notes has occurred and is continuing and an acceleration has
occurred, the Trustee may (as the Holders of 25% in aggregate principal amount
of the Outstanding Notes request in writing) direct the Collateral Agent to
foreclose upon and take possession of all Collateral.

          (d) If an Event of Default other than that referred to in Section
5.02(d) has occurred and is continuing and an acceleration has occurred, the
Trustee may (as the Required Holders request in writing) direct the Collateral
Agent to foreclose upon and take possession of all Collateral.

          (e) If an Event of Default occurs by reason of any willful action or
inaction taken or not taken by or on behalf of the Issuers with the intention of
avoiding payment of the premium that the Issuers would have had to pay if the
Issuers then had elected to redeem the Senior Secured Notes pursuant to the
optional redemption provisions of this Indenture, a premium equal to the then
applicable Treasury Rate shall also become and be immediately due and payable to
the extent permitted by law upon the acceleration of the Senior Secured Notes.

          Section 5.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal, premium, if any, and interest and all other amounts payable on the
Senior Secured Notes or to enforce the performance of any provision of the
Senior Secured Notes, this Indenture or any other Financing Document.

                                       85
<PAGE>

         The Trustee may maintain a proceeding even if it does not possess any
of the Senior Secured Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder of a Note in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. All remedies
are cumulative to the extent permitted by law.

         Section 5.04. Waiver of Past Defaults. Required Holders by notice to
the Trustee may on behalf of the Holders of all of the Senior Secured Notes
waive an existing Default or Event of Default and its consequences hereunder,
except a continuing Default or Event of Default in the payment of the principal
of, premium, if any, or interest on, the Senior Secured Notes provided, however,
that the Required Holders may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration. Upon
any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

         Section 5.05. Control by Majority. The Required Holders have the right
to direct the time, place and method of conducting any proceeding for any right
or remedy available to the Trustee or exercising any trust or power conferred on
the Trustee in this Indenture or in any other Financing Document.

         Section 5.06. Limitation on Suits. A Holder of a Senior Secured Note
may pursue a remedy with respect to this Indenture or the Senior Secured Notes
only if:

         (a) the Holder of a Senior Secured Note gives to the Trustee written
notice of a continuing Event of Default;

         (b) the Holders of at least 25% in principal amount of the then
outstanding Senior Secured Notes make a written request to the Trustee to pursue
the remedy;

         (c) such Holder of a Senior Secured Note or Holders of Senior Secured
Notes offer and, if requested, provide to the Trustee indemnity satisfactory to
the Trustee against any loss, liability or expense;

         (d) the Trustee does not comply with the request within sixty (60)
days after receipt of the request and the offer and, if requested, the provision
of indemnity; and

         (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Senior Secured Notes do not give the Trustee a
direction inconsistent with the request.

                                       86
<PAGE>

         A Holder of a Senior Secured Note may not use this Indenture to
prejudice the rights of another Holder of a Senior Secured Note or to obtain a
preference or priority over another Holder of a Senior Secured Note.

         Section 5.07. Rights of Holders of Senior Secured Notes to Receive
Payment. Notwithstanding any other provision of this Indenture, the right of any
Holder of a Senior Secured Note to receive payment of principal, premium, if
any, and interest on the Senior Secured Notes, on or after the respective due
dates expressed in the Senior Secured Notes (including in connection with an
offer to purchase), or to bring suit for the enforcement of any such payment on
or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

         Section 5.08. Collection Suit by Trustee. If an Event of Default
specified in Section 5.01(a) occurs and is continuing, the Trustee is authorized
to recover judgment in its own name and as trustee of an express trust against
the Issuers for the whole amount of principal of, premium, if any, and interest
remaining unpaid on the Senior Secured Notes and interest on overdue principal
and, to the extent lawful, interest and such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

         Section 5.09. Trustee May File Proofs of Claim. The Trustee is
authorized to file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel) and the Holders of the Senior Secured Notes
allowed in any judicial proceedings relative to either of the Issuers (or any
other obligor upon the Senior Secured Notes), their creditors or their property
and shall be entitled and empowered to collect, receive and distribute any money
or other property payable or deliverable on any such claims and any custodian in
any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee, and in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.07 hereof. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 6.07 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any

                                       87
<PAGE>

Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Senior Secured Notes or the rights of any Holder, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

         Section 5.10. Priorities. If the Trustee collects any money pursuant to
this Article, it shall be applied in the following order from time to time, on
the date or dates fixed by the Trustee: (i) first, to the payment of all amounts
due to the Trustee or any predecessor Trustee under this Indenture; (ii) second;
(A) in case the unpaid principal amount of the Outstanding Notes has not become
due, to the payment of any overdue interest, (B) in case a portion of the unpaid
principal amount of the Outstanding Notes has become due, first to the payment
of accrued interest on all Outstanding Notes for overdue principal, premium, if
any, and overdue interest, and next to the payment of the overdue principal on
all Senior Secured Notes or (C) in case all the unpaid principal amount of
Outstanding Notes has become due, first to the payment of the whole amount then
due and unpaid upon the Outstanding Notes for principal, premium, if any, and
interest, together with interest for overdue principal, premium, if any, and
overdue interest; and (iii) third, in case the unpaid principal amount of all
the Outstanding Notes has become due, and all of the outstanding principal,
premium, if any, interest and other amounts owed in connection with the Senior
Secured Notes have been fully paid, any surplus then remaining will be paid to
the Issuers, or to whomsoever may be lawfully entitled to receive the same, or
as a court of competent jurisdiction may direct.

         The Trustee may fix a record date and payment date for any payment to
Holders of Senior Secured Notes pursuant to this Section 5.10.

         Section 5.11. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section does not apply to a suit by the
Trustee, a suit by a Holder of a Senior Secured Note pursuant to Section 5.07
hereof, or a suit by Holders of more than 10% in principal amount of the then
outstanding Senior Secured Notes.

                                    Trustee

         Section 6.01. Duties of Trustee. (a) If an Event of Default actually
known to a Responsible Trust Officer has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

         (b) Except during the continuance of an Event of Default:

                  (i) the duties of the Trustee shall be determined solely by
         the express provisions of this Indenture and the Trustee need perform
         only those duties that are specifically set forth in this Indenture and
         no others, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

                 (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

         (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct or bad faith, except that:

                (i)   this paragraph does not limit the effect of paragraph (b)
          of this Section 6.01;

                (ii)  the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Trust Officer, unless it is proved
         that the Trustee was negligent in ascertaining the pertinent facts; and

                (iii) the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 5.05 hereof.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section.

                                       89
<PAGE>

          (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or incur any liability. The Trustee shall be under no
obligation to exercise any of its rights and powers under this Indenture at the
request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

          (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Issuers. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

          Section 6.02. Rights of Trustee. (a) The Trustee may conclusively rely
upon any document believed by it to be genuine and to have been signed or
presented by the proper Person. The Trustee need not investigate any fact or
matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require
and shall be entitled to an Officers' Certificate or an Opinion of Counsel or
both. The Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on such an Officers' Certificate or Opinion of
Counsel. The Trustee may consult with counsel and the advice, promptly confirmed
in writing thereafter, of such counsel or any Opinion of Counsel shall be full
and complete authorization and protection from liability in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.

          (c) The Trustee may act through its attorneys, custodians, nominees
and agents and shall not be responsible for the misconduct or negligence of any
agent, attorney, custodian or nominee appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

          (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Issuers shall be sufficient if

Officer, or if appropriate notice is provided in writing in accordance with
Section 6.02(g), as applicable, the Trustee shall mail to Holders of Senior
Secured Notes a notice of the Default or Event of Default within ninety (90)
days after it occurs. Except in the case of a Default or Event of Default in
payment of principal of, premium, if any, or interest on any Senior Secured
Note, the Trustee may withhold the notice if and so long as a committee of its
Responsible Trust Officers in good faith determines that withholding the notice

                                       91
<PAGE>

event described in TIA (S) 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also
shall comply with TIA (S) 313(b). The Trustee shall also transmit by mail all
reports as required by TIA (S) 313(c).

         A copy of each report at the time of its mailing to the Holders of

following Trustee's receipt thereof.

         Section 6.07. Compensation and Indemnity. The Issuers shall pay to the
Trustee from time to time reasonable compensation for its acceptance of this
Indenture and services hereunder as is now or hereafter agreed to in writing by
the Issuers and the Trustee. The Trustee's compensation shall not be limited by
any law on compensation of a trustee of an express trust. The Issuers shall

addition to the compensation for its services. Such expenses shall include the
reasonable and properly documented fees, disbursements and expenses of the
Trustee's agents and counsel.

against the Issuers (including this Section 6.07) and defending itself against
any claim (whether asserted by the Issuers or any Holder or any other person) or
liability in connection with the exercise or performance of any of the Trustee's
powers or duties hereunder, except to the extent any such loss, liability or
expense may be attributable to the Trustee's negligence or bad faith. The
Trustee shall notify the Issuers promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the
Issuers of their obligations hereunder. The Issuers shall defend the claim and
the Trustee shall reasonably cooperate in the defense. The Trustee may have
separate counsel (reasonably acceptable to the Issuers) and the Issuers shall
pay the reasonable fees and expenses of such counsel. The Issuers need not pay

shall have a Lien prior to the Senior Secured Notes on all money or property
held or collected by the Trustee, except that held in trust to pay principal and
interest on particular Senior Secured Notes.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.01(e), 9.13(k), 1.01(k) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses
of its agents and counsel) are intended to constitute expenses of administration

the trust hereby created by so notifying the Issuers. The Holders of Senior
Secured Notes of a majority in principal amount of the then outstanding Senior

the Issuers.

                                       93
<PAGE>

         If a successor Trustee does not take office within sixty (60) days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Issuers, or the Holders of Senior Secured Notes of at least 10% in principal
amount of the then outstanding Senior Secured Notes may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

         If the Trustee, after written request by any Holder of a Senior Secured
Note who has been a Holder of a Senior Secured Note for at least six (6) months,
fails to comply with Section 6.10, such Holder of a Senior Secured Note may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Senior Secured Notes. The retiring Trustee shall
promptly transfer all property held by it as Trustee to the successor Trustee,
provided all sums owing to the Trustee hereunder have been paid and subject to
the Lien provided for in Section 6.07 hereof. Notwithstanding replacement of the
Trustee pursuant to this Section 6.08, the Issuers' obligations under Section
6.07 hereof shall continue for the benefit of the retiring Trustee.

same, it being understood that all such information shall be received by the
Trustee as repository for said information and documents with no obligation on

                   Legal Defeasance and Covenant Defeasance

         Section 7.01. Option to Effect Legal Defeasance or Covenant Defeasance.
The Issuers may, at their option evidenced by an Officers' Certificate, at any
time, elect to have either Section 7.02 or 7.03 hereof be applied to all
outstanding Senior Secured Notes upon compliance with the conditions set forth
below in this Article 7.

         Section 7.02. Legal Defeasance and Discharge. Upon the Issuers'
exercise under Section 7.01 hereof of the option applicable to this Section
7.02, the Issuers shall, subject to the satisfaction of the conditions set forth
in Section 7.04 hereof, be deemed to have been discharged from their obligations
with respect to all outstanding Senior Secured Notes on the date the conditions
set forth below are satisfied (hereinafter, "Legal Defeasance"). For this
purpose, Legal Defeasance means that the Issuers shall be deemed to have paid
and discharged the entire Indebtedness represented by the outstanding Senior
Secured Notes, which shall thereafter be deemed to be "outstanding" only for the
purposes of Section 7.06 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all their other
obligations under such Senior Secured Notes and this Indenture (and the Trustee,
on demand of and at the expense of the Issuers, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Senior Secured Notes to receive payments in respect of the principal
of,

                                       95
<PAGE>

premium, if any, and interest on such Senior Secured Notes when such payments
are due from the trust referred to below, (b) the Issuers' obligations with
respect to the Senior Secured Notes concerning issuing temporary Senior Secured
Notes, registration of Senior Secured Notes, mutilated, destroyed, lost or
stolen Senior Secured Notes and the maintenance of an office or agency for
payment and money for security payments held in trust, (c) the rights, powers,
trusts, duties, immunities and indemnities of the Trustee, and the Issuers'
obligations in connection therewith and (d) this Article 7. Subject to
compliance with this Article 7, the Issuers may exercise their option under this
Section 7.02 notwithstanding the prior exercise of their option under Section
7.03 hereof.

         Section 7.03. Covenant Defeasance. Upon the Issuers' exercise under
Section 7.01 hereof of the option applicable to this Section 7.03, the Issuers
shall, subject to the satisfaction of the conditions set forth in Section 7.04
hereof, be released from their obligations under the covenants contained in
Sections 4.08 through 4.23, inclusive, hereof with respect to the outstanding
Senior Secured Notes on and after the date the conditions set forth in Section
7.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Senior Secured
Notes shall thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Senior Secured Notes shall not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Senior Secured Notes, the Issuers may omit to comply
with and shall have no liability in respect of any term, condition or limitation
set forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a Default or an Event of Default
under Section 5.01 hereof, but, except as specified above, the remainder of this
Indenture and such Senior Secured Notes shall be unaffected thereby. In
addition, upon the Issuers' exercise under Section 7.01 hereof of the option
applicable to this Section 7.03 hereof, subject to the satisfaction of the
conditions set forth in Section 7.04 hereof, Sections 5.01(b), 9.13(k), 1.01(k)
through 5.01(d) hereof shall not constitute Events of Default.

         Section 7.04. Conditions to Legal or Covenant Defeasance. The following
shall be the conditions to the application of either Section 7.02 or 7.03 hereof

Defeasance had not occurred;

          (c) in the case of an election under Section 7.03 hereof, the Issuers

Article 7 concurrently with such incurrence) or insofar as Section 5.01(f)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

          (e) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture) to which either Issuer is a party or by
which either Issuer is bound;

          (f) the Issuers shall have delivered to the Trustee an Opinion of

          (h) the Issuers shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

          Section 7.05. Release of Collateral upon Legal or Covenant Defeasance.
Upon Legal Defeasance or Covenant Defeasance, and upon satisfaction of the
requirements of Section 7.04 above, as applicable, the Collateral Agent shall

limited to, filing UCC-3 termination statements in the appropriate jurisdiction.

Trust; Other Miscellaneous Provisions. Subject to Section 7.07 hereof, all money

respect of the outstanding Senior Secured Notes shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Senior Secured
Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including either Issuer acting as Paying Agent) as the Trustee may
determine, to the Holders of such Senior Secured Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

          The Issuers shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 7.04 hereof or the principal

charge which by law is for the account of the Holders of the outstanding Senior
Secured Notes.

          Anything in this Article 7 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuers from time to time upon the request
of the Issuers any money or non-callable Government Securities held by it as
provided in Section 7.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 7.04(a) hereof), are in excess of the

                                       98
<PAGE>

amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance.

         Section 7.07. Repayment to Issuers. Any money deposited with the
Trustee or any Paying Agent, or then held by either of the Issuers, in trust for
the payment of the principal of, premium, if any, or interest on any Senior
Secured Note and remaining unclaimed for two (2) years after such principal, and
premium, if any, or interest has become due and payable shall be paid to such
Issuer on its request or (if then held by such Issuer) shall be discharged from
such trust; and the Holder of such Senior Secured Note shall thereafter, as a
secured creditor, look only to the Issuers for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Issuers as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Issuers cause to be
published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date

         Section 7.08. Reinstatement. If the Trustee or Paying Agent is unable
to apply any United States dollars or non-callable Government Securities in
accordance with Section 7.02 or 7.03 hereof, as the case may be, by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the Issuers'
obligations under this Indenture and the Senior Secured Notes shall be revived
and reinstated as though no deposit had occurred pursuant to Section 7.02 or
7.03 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 7.02 or 7.03 hereof, as the case may
be; provided, however, that, if the Issuers make any payment of principal of,
premium, if any, or interest on any Senior Secured Note following the
reinstatement of its obligations, the Issuers shall be subrogated to the rights
of the Holders of such Senior Secured Notes to receive such payment from the
money held by the Trustee or Paying Agent.

         It shall not be necessary for the consent of the Holders of Senior
Secured Notes under this Section 8.02 to approve the particular form of any
proposed amendment or waiver, but it shall be sufficient if such consent
approves the substance thereof.

         After an amendment, supplement or waiver under this Section becomes
effective, the Issuers shall mail to the Holders of Senior Secured Notes
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Issuers to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such amended
or supplemental Indenture or waiver or amendments to the Financing Documents.
Subject to Sections 5.04 and 5.07 hereof, the Holders of a majority in aggregate
principal amount of the Senior Secured Notes then outstanding voting as a single
class may waive compliance in a particular instance by the Issuers with any
provision of this Indenture or the Senior Secured Notes. However, without the
consent of all Holders of Outstanding Notes, an amendment or waiver under this
Section 8.02 may not (with respect to any Senior Secured Notes held by a
non-consenting Holder) modify:

         (a) the principal, premium, if any, and interest payable upon the
Senior Secured Notes;

         (b) the dates on which interest or principal on any Senior Secured
Notes is paid;

         (c) the dates of maturity of any Senior Secured Notes; and

                                      101
<PAGE>

         (d) the procedures for amendment by a supplemental indenture or
amendment.

         Notwithstanding anything in this Section 8.02, the provisions in
Section 3.09 relating to a Change of Control and the related definitions as used
therein may be amended by the Holders of at least a majority in aggregate
principal amount of the Outstanding Notes.

         Section 8.03. Revocation and Effect of Consents. Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder of a Senior
Secured Note is a continuing consent by the Holder of a Senior Secured Note and
every subsequent Holder of a Senior Secured Note or portion of a Senior Secured
Note that evidences the same debt as the consenting Holder's Senior Secured
Note, even if notation of the consent is not made on any Senior Secured Note.
However, any such Holder of a Senior Secured Note or subsequent Holder of a
Senior Secured Note may revoke the consent as to its Senior Secured Note if the
Trustee receives written notice of revocation before the date the waiver,
supplement or amendment becomes effective. An amendment, supplement or waiver
becomes effective in accordance with its terms and thereafter binds every
Holder.

         Section 8.04. Notation on or Exchange of Senior Secured Notes. The
Trustee may place an appropriate notation about an amendment, supplement or
waiver on any Senior Secured Note thereafter authenticated. The Issuers in
exchange for all Senior Secured Notes may issue and the Trustee shall, upon
receipt of an Authentication Order, authenticate new Senior Secured Notes that
reflect the amendment, supplement or waiver.

         Failure to make the appropriate notation or issue a new Senior Secured
Note shall not affect the validity and effect of such amendment, supplement or
waiver.

         Section 8.05. Trustee to Sign Amendments, Etc. The Trustee and the
Collateral Agent shall sign any amended or supplemental Indenture and amendments
to the other Financing Documents authorized pursuant to this Article 8 if the
amendment or supplement does not adversely affect the rights, duties,
liabilities, immunities or indemnities of the Trustee. In executing any amended
or supplemental indenture or amendments to the other Financing Documents, the
Trustee and the Collateral Agent shall be entitled to receive and (subject to
Section 6.01 hereof) shall be fully protected in relying upon, in addition to
the documents required by Section 9.04 hereof, an Officers' Certificate and an
Opinion of Counsel stating that the execution of such amended or supplemental
indenture or amendment to the other Financing Documents is authorized or
permitted by this Indenture.

         (a).  Principal and Interest. Project Orange Funding, L.P., a Delaware

this Senior Secured Note at 10.5% per annum from the date of issuance until

is not a Business Day, on the next succeeding Business Day Interest on the
Senior Secured Notes will accrue from the most recent Interest Payment Date to
which interest has been paid or, if no interest has been paid, from the date of
issuance; provided that if there is no existing Default in the payment of
interest, and if this Senior Secured Note is authenticated between a record date
referred to on the face hereof and the next succeeding Interest Payment Date,
interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be March 15, 2000. The

         (b).  Method of Payment. The Issuers will pay principal on the Senior
Secured Notes to the Persons who are registered Holders of Senior Secured Notes
at the close of business on the March 1 or September 1 next preceding the
relevant

                                      A-1
<PAGE>

payment date for principal, even if such Senior Secured Notes are canceled after
such record date and on or before such payment date for principal. The Issuers
will pay interest on the Senior Secured Notes (except defaulted interest) to the
Persons who are registered Holders of the Senior Secured Notes at the close of
business on the March 1 or September 1 next preceding the Interest Payment Date,
even if such Senior Secured Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. The Senior Secured Notes will be
payable as to principal, premium, if any, and interest at the office or agency
of the Issuers maintained for such purpose within or without the City and State

funds will be required with respect to principal of, interest and premium on all
Global Notes and all other Senior Secured Notes the Holders of which shall have
provided wire transfer instructions to the Issuers or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

         (c).  Paying Agent and Registrar.  Initially, U.S. Bank Trust National
Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar.  The Issuers may change any Paying Agent or Registrar without notice
to any Holder.  The Issuers may act in any such capacity.

         (d).  Indenture. The Issuers issued the Senior Secured Notes under the
Indenture and the terms of the Senior Secured Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb). The Senior
Secured Notes are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. To the extent any
provision of this Senior Secured Note conflicts with the express provisions of
the Indenture, the provisions of the Indenture shall govern and be controlling.
The Senior Secured Notes are limited to $68 million in aggregate principal
amount.

         (e).  Optional Redemption. The Senior Secured Notes will be redeemable
at the option of the Issuers at any time and from time to time, in whole or in
part, upon not less than 30 nor more than 60 days notice to each Holder of
Senior Secured Notes, at a redemption price equal to the Make-Whole Price.
"Make-Whole Price" means an amount equal to the greater of (i) 100% of the
principal amount of such Senior Secured Note and (ii) as determined by Reference
Adjusted Treasury Dealer, the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to the date of
redemption on a semi-annual basis (assuming a 360-day year consisting of twelve
30-day months) at the Treasury Rate, plus, in each case, accrued and unpaid
interest thereon to the Redemption Date. Unless the Issuers default in payment
of the redemption price, on

                                      A-2
<PAGE>

and after the Redemption Date, interest will cease to accrue on the Senior
Secured Note or portions thereof called for redemption.

         (f).  Mandatory Redemption. The Senior Secured Notes will be subject to
mandatory redemption, in whole or in part, at a redemption price equal to the
principal amount thereof plus accrued and unpaid interest to the Redemption Date
upon: (a) upon the receipt of Loss Proceeds or Eminent Domain Proceeds by POA if
POA determines that (i) the Project cannot be rebuilt, repaired or restored to
permit operations on a commercially reasonable basis, or POA determines not to
rebuild, repair or restore the Project, in which case the amount of such Loss
Proceeds or Eminent Domain Proceeds shall be available for such redemption, or
(ii) only a portion of the Project is capable of being rebuilt, repaired or
restored, in which case if excess proceeds exist after such rebuild, repair, or
restoration, only the amount of such excess Loss Proceeds or Eminent Domain
Proceeds shall be made available for such redemption; (b) the receipt by POA of
proceeds in connection with a Title Event, in which case the amount of such
Title Event Proceeds shall be made available for such redemption, subject to
reduction by the costs expended in connection with collecting proceeds upon the
occurrence of such Title Event, and any additional reasonable costs or expenses
that the Issuers will be subject to as a result of the Title Event; and (c) the
receipt by POA of payments arising from the occurrence of a Contract Termination
Event in which case the amount of all such payments shall be made available for
such redemption subject to reduction in the case of a Contract Termination Event
relating to the Gas Purchase Agreement, by the costs expended in connection with
obtaining a replacement or substitute gas supply and funding the Gas Reserve
Account.

         (g).  Notice of Redemption. Notice of redemption will be mailed at
least 30 days but not more than 60 days before the redemption date to each
Holder whose Senior Secured Notes are to be redeemed at its registered address.
The Trustee shall promptly notify the Issuers in writing of the Senior Secured
Notes selected for redemption and, in the case of any Senior Secured Note
selected for partial redemption, the principal amount thereof to be redeemed.
Senior Secured Notes and portions of Senior Secured Notes selected shall be in
denominations of $100,000 and integral multiples of $1,000 in excess thereof;
except that if all of the Senior Secured Notes of a Holder are to be redeemed,
the entire outstanding amount of Senior Secured Notes held by such Holder, even
if not a multiple of $1,000, shall be redeemed. Except as provided in the
preceding sentence, provisions of the Indenture that apply to Senior Secured
Notes called for redemption also apply to portions of Senior Secured Notes
called for redemption.

         (h).  Denominations, Transfer, Exchange. The Senior Secured Notes are
in registered form without coupons in denominations of $100,000 and integral
multiples of $1,000 in excess thereof. The transfer of the Senior Secured Notes
may be registered and Senior Secured Notes may be exchanged as provided in the
Indenture. The Registrar and the Trustee may require a Holder, among other

                                      A-3
<PAGE>

things, to furnish appropriate endorsements and transfer documents and the
Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuers need not exchange or register the
transfer of any Senior Secured Notes or portion of a Senior Secured Note
selected for redemption, except for the unredeemed portion of any Senior Secured
Note being redeemed in part. Also, the Issuers need not exchange or register the
transfer of any Senior Secured Notes for a period of 15 days before a selection
of the Senior Secured Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

         (i).  Persons Deemed Owners. The registered Holder of a Senior Secured
Note may be treated as its owner for all purposes.

         (j).  Amendment, Supplement and Waiver. Subject to certain exceptions,
the Indenture or the Senior Secured Notes may be amended or supplemented with
the consent of the Holders of at least a majority in principal amount of the
then outstanding Senior Secured Notes and any existing default or compliance
with any provision of the Indenture or the Senior Secured Notes may be waived
with the consent of the Holders of a majority in principal amount of the then
outstanding Senior Secured Notes. Without the consent of any Holder of a Senior
Secured Note, the Indenture or the Senior Secured Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to add additional
covenants of the Issuers or to surrender right conferred upon the Issuers, to
increase the assets securing the Issuers' obligations under the Indenture, to
make any change that would provide any additional rights or benefits to the
Holders of the Senior Secured Notes or that does not adversely affect the legal
rights under the Indenture of any such Holder, to comply with the requirements
of the Securities and Exchange Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act, to reflect any
amendments required by a Rating Agency in circumstances where confirmation of
the Ratings is required or permitted under the Indenture.

         (k).  Defaults and Remedies. Events of Default include: (i) failure to
pay any principal, premium, if any, and interest or other amounts owed on any
Senior Secured Note when the same becomes due and payable, whether by scheduled
maturity or required prepayment or redemption or by acceleration or otherwise,
and such failure continues for 5 days or more following the due date for
payment; or (ii) any representation or warranty made by the Issuers in the
Indenture or in any other Financing Document or any representation, warranty or
statement in any certificate, financial statement or other document furnished to
the Trustee or any other Person by or on behalf of either of the Issuers or any
other Credit Party proves to have been untrue or misleading in any material
respect as of the time made, confirmed or furnished and the fact, event or
circumstance that gave rise to such inaccuracy has resulted in, or could
reasonably be expected to result in, a Material Adverse Effect and that fact,
event or circumstance continues uncured for 30 or more days from the date the
POA receives notice thereof from the Trustee; provided that, if such Issuer or
other Credit

                                      A-4
<PAGE>

Party commences and diligently pursues efforts to cure such fact, event or
circumstance within such 30-day period and deliver written notice to the Trustee
thereof, such Issuer or other Credit Party may continue to effect such cure, and
such misrepresentation shall not be deemed an "Event of Default" for an
additional 60 days so long as such Issuer or other Credit Party is diligently
pursuing such cure; or (iii) (A) either Issuer fails to pay any Imposition as
and when due and payable, and such failure continues for 15 days or more
following the date such payment becomes delinquent; or (B) either Issuer fails
to perform or observe any covenant, agreement or provision binding upon it
contained in the Indenture or any of the other Financing Documents regarding
maintenance of existence or restrictions on Indebtedness, Liens, Restricted
Payments, Guarantees, Investments, Sale Lease-Back Transactions, Affiliate
Transactions, Project Documents, disposition of assets, operation of the
Project, fundamental changes, or nature of business and such failure continues
uncured for 30 or more days from the date POA receive notice thereof from the
Trustee; or if such Issuer fails to perform or observe any covenant, agreement
or provision binding upon it contained in any of the Project Documents and such
failure continues uncured for 30 or more days from the date POA receives notice
thereof from the Trustee (provided that the same does not constitute an event of
default under the relevant Project Document), or (C) an event that then gives
any Person the right to terminate or materially adversely affect any of POA's
rights under the relevant Project Document; or (D) if any event of default by
POA under any of the Project Documents, or any event arises that in either case
then gives any Person (other than POA) the right to terminate or materially
adversely affects any of POA's rights under any of the Project Documents, shall
occur and be continuing; or (E) any event that then gives the University the
right to foreclose under any University Collateral Document; or (F) the
commencement and continuance of any action, suit or proceeding for the
foreclosure, including foreclosure any power of sale, of any lien on or a
security interest in any Collateral, including any such foreclosure under any
University Collateral Document; or (iv) either Issuer or any other Credit Party
fails to perform or observe any covenant, agreement or provision binding upon it
contained in the Indenture or any of the other Financing Documents (other than
those referred to in clauses (i) through (iii) inclusive above and (v) through
(vii) inclusive below) and such failure continues uncured for 30 or more days
from the date POA receives notice thereof from the Trustee of such failure;
provided that if such Issuer or other Credit Party commences and diligently
pursues efforts to cure such default within such 30-day period, such Issuer or
other Credit Party may continue to effect such cure of the default and such
default will not be deemed an "Event of Default" for an additional 90 days so
long as such Issuer or other Credit Party is diligently pursuing such cure; or
(v) either Issuer: (A) admits in writing its inability, or is generally unable,
to pay its debts as the debts become due or makes a general assignment for the
benefit of creditors; or (B) commences any case, proceeding or other action
seeking reorganization, arrangement, adjustment, liquidation, dissolution or
composition of it or its debts under any applicable Debtor Relief Law; or (C) in
any involuntary case, proceeding or other action commenced against it which
seeks to have an order for relief (injunctive or otherwise) entered against it,
as debtor, or seeks reorganization, arrangement, adjustment, liquidation,
dissolution or

                                      A-5
<PAGE>

composition of it or its debts under any Debtor Relief Law, (x) fails to obtain
a dismissal of such case, proceeding or other action within 90 days of its

Agent for the benefit of the Secured Parties on the Collateral described therein
with the priority purported to be created thereby; provided, however, that POA
shall have 10 days after POA obtains actual knowledge thereof to cure any such
cessation, if curable, or to furnish to the Collateral Agent all documents or
instruments required to cure any such cessation, if curable; or (vii) any event
of default under any Permitted Indebtedness of either Issuer which results in

         (l).  Trustee Dealings with Issuer. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for either Issuer or their Affiliates, and may otherwise deal with
either Issuer or their Affiliates, as if it were not the Trustee.

         (m).  No Recourse Against Others. A past, present or future director,
officer, employee, incorporator, management committee, stockholder or partner of
either of the Issuers, as such, shall not have any liability for any obligations
of either of Issuers under the Senior Secured Notes, the Indenture, any
Financing Documents or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each Holder by accepting a Senior Secured
Note waives and releases all such liability the waiver and release are part of
the consideration for the issuance of the Senior Secured Notes. This Section 13
shall not affect or diminish or constitute a waiver, release or discharge of any
specific written obligation, covenant, or agreement made by any person in any
Financing Document to which it is a party or any security granted by any person
as security for the obligations of the Issuers.

         (n).  Authentication. This Senior Secured Note shall not be valid until

and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

representation is made as to the accuracy of such numbers either as printed on
the Senior Secured Notes or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

charge a copy of the Indenture. Requests may be made to:

Indenture and such Act for a statement of such terms. To the extent any

Proceeds or Eminent Domain Proceeds shall be available for such redemption, or

restored, in which case if excess proceeds exist after such rebuild, repair, or
restoration, only the amount of such excess Loss Proceeds or Eminent Domain

proceeds in connection with a Title Event, in which case the amount of such

Notes and portions of Senior Secured Notes selected shall be in denominations of
$100,000 and integral multiples of $1,000 in excess thereof; except that if all
of the Senior Secured Notes of a Holder are to be redeemed, the entire
outstanding amount of Senior Secured Notes held by such Holder, even if not a
multiple of $1,000, shall be redeemed. Except as provided in the preceding
sentence, provisions of the Indenture that apply to Senior Secured Notes called
for redemption also apply to portions of Senior Secured Notes called for

Notes may be registered and Senior Secured Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuers need not exchange or register the
transfer of any Senior Secured Notes or portion of a Senior Secured Note
selected for redemption, except for the unredeemed portion of any Senior Secured
Note being redeemed in part. Also, the Issuers need not exchange or register the
transfer of any Senior Secured Notes for a period of 15 days before a selection
of the Senior Secured Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

     (i). Persons Deemed Owners.  The registered Holder of a Senior Secured Note
may be treated as its owner for all purposes.

     (j). Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture or the Senior Secured Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the then
outstanding Senior Secured Notes and any existing default or compliance with any
provision of the Indenture or the Senior Secured Notes may be waived with the
consent of the Holders of a majority in principal amount of the then outstanding
Senior Secured Notes. Without the consent of any Holder of a Senior Secured
Note, the Indenture or the Senior Secured Notes may be amended or supplemented
to cure any ambiguity, defect or inconsistency, to add additional covenants of
the Issuers or to surrender right conferred upon the Issuers, to increase the
assets securing the Issuers' obligations under the Indenture, to make any change
that would provide any additional rights or benefits to the Holders of the
Senior Secured Notes or that does not adversely affect the legal rights under
the Indenture of any such Holder, to comply with the requirements of the
Securities and Exchange Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act, to reflect any
amendments required by a Rating Agency in circumstances where confirmation of
the Ratings is required or permitted under the Indenture.

     (k). Defaults and Remedies. Events of Default include: (i) failure to pay
any principal, premium, if any, and interest or other amounts owed on any Senior
Secured Note when the same becomes due and payable, whether by scheduled
maturity or required prepayment or redemption or by acceleration or otherwise,
and such failure continues for 5 days or more following the due date for
payment; or (ii) any representation or warranty made by the Issuers in the
Indenture or in any other Financing Document or any representation, warranty or
statement in any certificate, financial statement or other document furnished to
the Trustee or any other Person by or on behalf of either of the Issuers or any
other Credit Party proves to have been untrue or misleading in any material
respect as of the time made, confirmed or furnished and the fact, event or
circumstance that gave rise to such inaccuracy has resulted in, or

                                      B-7
<PAGE>

could reasonably be expected to result in, a Material Adverse Effect and that

the POA receives notice thereof from the Trustee; provided that, if such Issuer
or other Credit Party commences and diligently pursues efforts to cure such
fact, event or circumstance within such 30-day period and deliver written notice
to the Trustee thereof, such Issuer or other Credit Party may continue to effect
such cure, and such misrepresentation shall not be deemed an "Event of Default"
for an additional 60 days so long as such Issuer or other Credit Party is
diligently pursuing such cure; or (iii) (A) either Issuer fails to pay any
Imposition as and when due and payable, and such failure continues for 15 days
or more following the date such payment becomes delinquent; or (B) either Issuer

Transactions, Project Documents, disposition of assets, operation of the
Project, fundamental changes, or nature of business and such failure continues
uncured for 30 or more days from the date POA receive notice thereof from the
Trustee; or if such Issuer fails to perform or observe any covenant, agreement
or provision binding upon it contained in any of the Project Documents and such
failure continues uncured for 30 or more days from the date POA receives notice
thereof from the Trustee (provided that the same does not constitute an event of
default under the relevant Project Document), or (C) an event that then gives
any Person the right to terminate or materially adversely affect any of POA's
rights under the relevant Project Document; or (D) if any event of default by
POA under any of the Project Documents, or any event arises that in either case
then gives any Person (other than POA) the right to terminate or materially
adversely affects any of POA's rights under any of the Project Documents, shall
occur and be continuing; or (E) any event that then gives the University the
right to foreclose under any University Collateral Document; or (F) the

foreclosure, including foreclosure any power of sale, of any lien on or a
security interest in any Collateral, including any such foreclosure under any

fails to perform or observe any covenant, agreement or provision binding upon it
contained in the Indenture or any of the other Financing Documents (other than
those referred to in clauses (i) through (iii) inclusive above and (v) through
(vii) inclusive below) and such failure continues uncured for 30 or more days
from the date POA receives notice thereof from the Trustee of such failure;
provided that if such Issuer or other Credit Party commences and diligently
pursues efforts to cure such default within such 30-day period, such Issuer or
other Credit Party may continue to effect such cure of the default and such
default will not be deemed an "Event of Default" for an additional 90 days so

(v) either Issuer: (A) admits in writing its inability, or is generally unable,
to pay its debts as the debts become due or makes a general assignment for the
benefit of creditors; or (B) commences any case, proceeding or other action
seeking reorganization, arrangement, adjustment, liquidation,

                                      B-8
<PAGE>

dissolution or composition of it or its debts under any applicable Debtor Relief
Law; or (C) in any involuntary case, proceeding or other action commenced
against it which seeks to have an order for relief (injunctive or otherwise)
entered against it, as debtor, or seeks reorganization, arrangement, adjustment,
liquidation, dissolution or composition of it or its debts under any Debtor
Relief Law, (x) fails to obtain a dismissal of such case, proceeding or other

Collateral described therein with the priority purported to be created thereby;
provided, however, that POA shall have 10 days after POA obtains actual
knowledge thereof to cure any such cessation, if curable, or to furnish to the
Collateral Agent all documents or instruments required to cure any such
cessation, if curable; or (vii) any event of default under any Permitted
Indebtedness of either Issuer which results in Permitted Indebtedness in excess

     (l). Trustee Dealings with Issuer. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for either Issuer or their Affiliates, and may otherwise deal with either Issuer
or their Affiliates, as if it were not the Trustee.

     (m). No Recourse Against Others. A past, present or future director,
officer, employee, incorporator, management committee, stockholder or partner of
either of the Issuers, as such, shall not have any liability for any obligations
of either of Issuers under the Senior Secured Notes, the Indenture, any
Financing Documents or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each Holder by accepting a Senior Secured
Note waives and releases all such liability the waiver and release are part of
the consideration for the issuance of the Senior Secured Notes. This Section 13
shall not affect or diminish or constitute a waiver, release or discharge of any
specific written obligation, covenant, or agreement made by any person in any
Financing Document to which it is a party or any security granted by any person
as security for the obligations of the Issuers.

     (n). Authentication. This Senior Secured Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.
