transfer or exchange in form satisfactory to, Indenture Trustee and 
Nonaffiliated Partner Trustee, duly executed by the requesting Holder or such 
Holder's attorney duly authorized in writing.

       No service charge shall be made to a Holder for any registration of 
transfer or exchange of Notes, but the Registrar may require payment of a sum 
sufficient to cover any tax or other governmental charge that may be imposed 
in connection with any registration of transfer or exchange of Notes.

       The Registrar shall not be required (a)  to register the transfer of 
or to exchange any Note during a period beginning at the opening of business 
10 days before the day of the scheduled prepayment (or purchase in lieu of 
prepayment where applicable) of Notes pursuant to Section 6.1 or 8.3(e) and 
ending at the close of business on the scheduled date of prepayment (or 
purchase) or (b)  to register the transfer of or to exchange any Note called 
for prepayment (or purchase in lieu of prepayment where applicable) pursuant 
to such Section 6.1 or 8.3(e).

       2.5    INDENTURE TRUSTEE AS AGENT; OWNERSHIP OF NOTES.

              (a)    Indenture Trustee is hereby appointed the agent of 
Nonaffiliated Partner Trustee for the payment, registration, transfer and 
exchange of Notes.  Subject to the provisions of Section 2.8, Notes may be 
presented for payment at, and notices or demands with respect to the Notes or 
this Indenture may be served 


                                     -14-

or made at, the principal corporate trust office of Indenture Trustee.  
Indenture Trustee shall promptly notify Nonaffiliated Partner Trustee of any 
such presentment, notice or demand; provided, however, that the failure of 
Indenture Trustee to so notify Nonaffiliated Partner Trustee shall not affect 
the obligations of Nonaffiliated Partner Trustee hereunder or under the Notes 
or, absent gross negligence or wilful misconduct, give rise to any liability 
of Indenture Trustee to Nonaffiliated Partner Trustee or to any other Person 
for any such failure.

              (b)    Ownership of the Notes shall be proved by the Register 
kept by the Registrar.  Prior to due presentment for registration of transfer 
of any Note, Nonaffiliated Partner Trustee and Indenture Trustee shall 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, 
Premium, if any, and interest on such Note and for all other purposes 
whatsoever, whether or not such Note is overdue, and neither Nonaffiliated 
Partner Trustee nor Indenture Trustee shall be affected by notice to the 
contrary.

       2.6    MUTILATED, DESTROYED, LOST OR STOLEN NOTES.  If any Note is 
mutilated, destroyed, lost or stolen, Nonaffiliated Partner Trustee shall, 
upon the written request of the relevant Holder, issue and execute, and 
Indenture Trustee shall authenticate and deliver to the relevant Holder in 
replacement thereof, a new Note of the same date of original issue and having 
the same Payment Dates, Debt Rate and Maturity Date, payable to the same 
Holder in the same principal amount and dated the same date as the Note so 
mutilated, destroyed, lost or stolen.  If the Note being replaced has become 
mutilated, such Note shall be surrendered to Indenture Trustee.  If the Note 
being replaced has been destroyed, lost or stolen, the relevant Holder shall 
furnish to Nonaffiliated Partner Trustee and Indenture Trustee (i)  such 
security or indemnity as may be required by them to save Nonaffiliated 
Partner Trustee and Indenture Trustee harmless and (ii)  evidence 
satisfactory to Nonaffiliated Partner Trustee and Indenture Trustee of the 
destruction, loss or theft of such Note and of the ownership thereof.  If the 
original Holder or such other Person that is an institutional investor is the 
owner of any such destroyed, lost or stolen Note, then the affidavit of the 
President, any Vice President, Assistant Vice President, Treasurer or 
Secretary of the original Holder or such other Person setting forth the fact 
of destruction, loss or theft and of its ownership of the Note, at the time 
thereof, shall be accepted as satisfactory evidence thereof, and no indemnity 
shall be required as a condition to the execution 

                                     -15-

and delivery of a new Note other than the written agreement of such original 
Holder or other Person reasonably satisfactory to Nonaffiliated Partner 
Trustee and Indenture Trustee to indemnify (including for any costs and 
expenses, including reasonable attorneys' fees) Nonaffiliated Partner Trustee 
and Indenture Trustee for any claims or actions against them resulting from 
the issuance of such new Note or the reappearance of the old Note.  Each Note 
issued pursuant to this Section 2.6 shall bear a notation by Indenture 
Trustee of (a)  the aggregate amounts of principal of, and Premium, if any, 
on, such mutilated, destroyed, lost or stolen Note that were paid to any 
Holder thereof at any time before the delivery of such new Note and (b)  the 
date to which interest on such mutilated, destroyed, lost or stolen Note had 
been paid to any Holder thereof at or prior to the time of such delivery.

       2.7    CANCELLATION.  All Notes surrendered for the purpose of 
payment, redemption, transfer or exchange shall be delivered to Indenture 
Trustee for cancellation or, if surrendered to Indenture Trustee, shall be 
canceled by it, and no Notes shall be issued in lieu thereof except as 
expressly required or permitted by this Indenture.  Indenture Trustee shall 
deliver a certificate to Nonaffiliated Partner Trustee specifying any 
cancellation of Notes that has been made.  All such canceled Notes shall be 
held by Indenture Trustee until this Indenture is discharged, at which time 
Indenture Trustee shall either deliver such canceled Notes in a manner 
necessary to effect the discharge and release of this Indenture or, if no 
such delivery is necessary, such Notes shall be delivered to or disposed of 
as directed by Nonaffiliated Partner Trustee.

       2.8    PAYMENT ON NOTES.

              (a)    The principal of, the Premium, if any, interest on, and 
any other amounts payable with respect to, the Notes shall be payable at the 
principal office of Indenture Trustee, in lawful money of the United States 
of America without surrender or presentation of such Note and without any 
notation being made thereon.  The Holder (or the Person for whom such Holder 
is a nominee) will, before selling, transferring or otherwise disposing of 
such Note, present such Note to Indenture Trustee for transfer and notation 
as provided in Section 2.4.  Any payment or prepayment of amounts due on the 
Notes in accordance with the terms thereof and hereof which is due on a date 
that is not a Business Day shall be payable, at the election of Nonaffiliated 
Partner Trustee, on the next following Business Day without penalty or 
reduction of, or increase in, the amount of interest that is payable thereon.

              (b)    Notwithstanding Section 2.8(a), if any Note is held by 
the original Note Purchaser, a permitted successor or assign that is an 
institutional investor or a nominee thereof, Indenture Trustee shall, if 
requested in writing by such Holder, pay interest on such Note and pay or 
prepay the principal thereof and the Premium, if any, thereon and shall pay 
all other amounts due with respect to such Note, by check, duly mailed, by 
first-class mail, postage prepaid, or delivered to such Holder at its address 
appearing on the Register.  Upon written notice from any Holder that is an 
original Note Purchaser, a permitted successor or assign that is an 
institutional investor or a nominee thereof, which notice shall be given not 
less than 30 days before the payment or prepayment of the Notes (and Section 
2.16 shall constitute such written notice and wire transfer instructions 
until otherwise designated in the case of the Note Purchasers), Indenture 
Trustee will pay interest on such Note and pay or prepay the principal 
thereof and the Premium, if any thereon, by wire transfer of immediately 
available funds to such institution in the continental United States as such 
Holder may designate in such notice, such wire transfers to be made on each 
date on which such payment or prepayment is due if, and only so long as, such 
institution has facilities for the receipt of a wire transfer. Indenture 
Trustee will transmit any such wire transfer from its offices not later than 
1:00 p.m. (New York time) on each date on which payment or prepayment is due 
if, and only so long as, available funds therefor have been received by 
Indenture Trustee by 11:00 a.m. (New York time) on such date or, if Indenture 
Trustee has not received such available funds, Indenture Trustee will 
transmit such wire transfer promptly upon receipt of such available funds.

              (c)    A Holder shall have no further interest in, or other 
right with respect to, the Indenture Estate when and if the principal amount 
of, Premium, if any, and interest on all Notes held by such Holder and all 
other sums payable to such Holder and secured hereunder are paid in full.

       2.9    PAYMENT FROM INDENTURE ESTATE ONLY; NONRECOURSE OBLIGATIONS; 
EXCESS AMOUNTS.

              (a)    All amounts payable by Indenture Trustee and 
Nonaffiliated Partner Trustee under the Notes, this Indenture and the 
relevant Indenture Supplement shall be made only from the income and proceeds 
of the Indenture Estate and each Holder by its acceptance of its Note agrees 
that (i) it will look solely to such Indenture Estate for the payment of such 
amounts, to the extent 

                                     -17-

<PAGE>

available for distribution to it as herein provided, and (ii) none of 
Nonaffiliated Partner Trustee, any Beneficiary, Indenture Trustee or any of 
their permitted successors or assigns, is or shall be personally liable to 
any Holder for any amount payable under such Note or this Indenture, except, 
in the case of Nonaffiliated Partner Trustee and Indenture Trustee and any of 
their permitted successors or assigns, as expressly provided in this 
Indenture. Notwithstanding any other provision of this Indenture, including 
Section 9, First Security shall be liable hereunder in its individual 
capacity for its own willful misconduct or gross negligence or, in the case 
of the holding or transfer of funds, the failure to act with the same care as 
it uses in the handling of its own funds.

              (b)    First Security is entering into this Indenture solely as 
Nonaffiliated Partner Trustee under the Trust Agreement and not in its 
individual capacity, and in no case whatsoever shall First Security, or any 
entity acting as successor trustee under the Trust Agreement, be personally 
liable for, or for any loss in respect of, any statements, representations, 
warranties, agreements or obligations hereunder or thereunder; provided that 
First Security shall be liable hereunder (i) for the performance of its 
agreements under Sections 3.5(c), 5.5 and 5.9 of the Participation Agreement, 
and (ii) for its own willful misconduct or gross negligence or, in the case of 
the holding and transfer of funds, the failure to act with the same care as 
it uses in the handling of its own funds.  If a successor Nonaffiliated 
Partner Trustee is appointed in accordance with the terms of Section 8 of the 
Trust Agreement and the Participation Agreement, such successor Nonaffiliated 
Partner Trustee shall, without any further act, succeed to all of the rights, 
duties, immunities and obligations hereunder, and its predecessor 
Nonaffiliated Partner Trustee and First Security shall be released from all 
further duties and obligations hereunder, without prejudice to any claims 
against such predecessor Nonaffiliated Partner Trustee or First Security, for 
any default by such predecessor Nonaffiliated Partner Trustee or First 
Security, respectively, in the performance of its obligations hereunder prior 
to such appointment.

              (c)    If (i) all or any part of the Trust Estate becomes the
property of, or any Beneficiary becomes, a debtor subject to the reorganization
provisions of the Bankruptcy Reform Act of 1978 or any successor provision,
(ii) pursuant to such reorganization provisions, First Security or any
Beneficiary is required, by reason of First Security or any Beneficiary being
held to have recourse liability to the Holders or Indenture Trustee, 

                                     -18-

<PAGE>

directly or indirectly, to make payment on account of the principal of, 
Premium, if any, or interest on the Notes and (iii) any Holder or Indenture 
Trustee actually receives any Excess Amount (as defined below) which reflects 
any payment by First Security or any Beneficiary on account of clause (ii) 
above, then such Holder or Indenture Trustee, as the case may be, shall 
promptly refund to First Security or such Beneficiary (whichever shall have 
made such payment) such Excess Amount.  For purposes of this Section 2.9, 
"Excess Amount" means the amount by which any payment required to be made by 
First Security or any Beneficiary under clause (ii) above exceeds the amount 
which would have been received by the Holder(s) or Indenture Trustee if First 
Security or such Beneficiary had not become subject to the recourse liability 
referred to in clause (ii) above.

       2.10   EXECUTION AND DELIVERY OF NOTES UPON ORIGINAL ISSUANCE. 
Nonaffiliated Partner Trustee shall issue, execute and deliver to Indenture 
Trustee, and Indenture Trustee shall authenticate and deliver to Holders, the 
Notes for original issuance only upon payment by Holders pursuant to the 
Participation Agreement of an amount equal to the aggregate original 
principal amount of the Notes.

       2.11   SECURITY FOR AND PARITY OF NOTES.  It is the intention of the 
parties hereto that all Notes issued and Outstanding hereunder rank on a 
parity with each other Note and, that as to each other Note, they be secured 
equally and ratably by the collateral described in this Indenture and any 
Indenture Supplement without preference, priority or distinction of any one 
thereof over any other by reason of difference in time of issuance, or 
otherwise, and that each such Note be entitled to the same benefits and 
security in this Indenture and any Indenture Supplement as each other such 
Note.

       2.12   APPLICATION OF PAYMENTS TO NOTES.  In the case of each Note, 
each payment of principal of, and Premium, if any, and interest on such Note, 
shall be applied, first, to the payment of accrued but unpaid interest on 
such Note (including any interest at the Late Rate on overdue principal, 
Premium and (to the extent permitted by applicable law) interest) to the date 
of such payment, second, the balance, if any, remaining thereafter to the 
payment of the principal amount due and payable on such Note, and third, the 
balance, if any, remaining thereafter, to the payment of Premium, if any, 
then due and payable on such Note, provided that such Note shall not be 
subject to prepayment or redemption by Nonaffiliated Partner Trustee except 
as provided in Sections 6.1 and 8.3(e).

       2.13   INTENTIONALLY OMITTED.

       2.14   LATE RATE.  If Nonaffiliated Partner Trustee, any Beneficiary 
or a Person designated by any of them elects or is required to redeem, 
prepay, pay or purchase any Note (in whole or in part) under any provision of 
this Indenture or any other Basic Document, and such redemption, prepayment 
or purchase is not consummated on the date originally scheduled therefor 
(unless, following General Partner's election to remove the Unit or Units 
from the Lien of the Indenture pursuant to Section 5.16 of the Participation 
Agreement, to exercise its ET Right pursuant to Section 9.1 of the 
Partnership Agreement, or to exercise its Special P.O. Right pursuant to 
Section 9.4 of the Partnership Agreement, Nonaffiliated Partner Trustee 
provides written notice to Indenture Trustee and each Holder no later than 
eight Business Days before such originally scheduled prepayment date to the 
effect that such termination or purchase will not occur and accordingly it 
will not be prepaying the Notes on such date), the Notes shall accrue 
interest at the Late Rate from such originally scheduled date for prepayment 
to the date of payment, payable on demand.

       2.15   DEFINITION OF PREMIUM. As used herein "Premium" means as at any 
date a payment thereof is due (the "payment date") in connection with payment 
or prepayment in respect of any of the Notes the excess of (i)  the present 
value as at the payment of the Prepaid Cash Flows, discounted semiannually at 
an annual rate which is equal to the Treasury Rate plus 0.50% over (ii)  the 
aggregate principal amount of such Notes then to be paid or prepaid.  To the 
extent that the Treasury Rate plus 0.50% at the time of determination of the 
Premium is equal to or higher than the rate of interest then borne by such 
Notes, the Premium shall be zero.

              The following terms shall have the following meanings:

              "PREPAID CASH FLOWS" -- for each date on which a payment of
       principal or interest, or both, is scheduled to become due on the Notes,
       an amount determined by subtracting (x) the amount of such payment
       scheduled to become due on such date after giving effect to any
       prepayment of principal that was originally scheduled to be paid on the
       date as to which the determination is being made from (y) the amount of
       such payment (exclusive of interest accrued to the date of such
       prepayment) which would have become due on such date but for such
       prepayment.

              "STATISTICAL RELEASE" -- the then most recently published
       statistical release designated "H.15(519)" or any successor publication
       which is published weekly by the Federal Reserve System and which
       establishes yields on actively traded U.S. government securities adjusted
       to constant maturities or, if such statistical release is not published
       at the time of any determination hereunder, such other reasonably
       comparable index which shall be designated by a Majority In Interest.

              "TREASURY RATE" -- the yield to maturity of actually traded United
       States Treasury obligations with a constant maturity (rounded to the
       nearest month) corresponding to the remaining Weighted Average Life to
       Maturity of the Prepaid Cash Flows as set forth on page 5 of the Telerate
       or, if not available, on page "USD" of the Bloomberg Financial Markets
       Screen (or, if not available, any other nationally recognized trading
       screen reporting on-line intraday trading in United States government
       securities) at 10:00 a.m. (New York City time) on the second Business Day
       before the date fixed for prepayment, or in the event no such nationally
       recognized trading screen reporting on-line intraday trading in United
       States government securities is available, the arithmetic mean of the two
       most recent yields under the heading "week ending" published in the
       Statistical Release opposite the caption "Treasury Constant Maturities"
       for the maturity (rounded to the nearest month) corresponding to the
       Weighted Average Life to Maturity of the Prepaid Cash Flows.  If no
       maturity exactly corresponding to the remaining Weighted Average Life to
       Maturity of the Prepaid Cash Flows shall appear therein, yields for the
       two most closely corresponding published maturities shall be calculated
       pursuant to the foregoing sentence and the Treasury Rate shall be
       interpolated or extrapolated from such yields on a straight-line basis
       (rounding to the nearest month).  If such rates shall not have been so
       published, the Treasury Rate in respect of such determination date shall
       be calculated pursuant to the next preceding sentence on the basis of the
       arithmetic mean of the arithmetic means of the secondary market ask
       rates, as of approximately 3:30 p.m. (New York City time) on the last
       Business Days of each of the two weeks preceding the payment date, for
       the actively traded U.S. Treasury security or securities with a maturity
       or maturities most closely corresponding to the remaining Weighted
       Average Life to Maturity of the Prepaid Cash Flows as at such payment or
       prepayment date, as reported by three primary United States

                                     -21-

<PAGE>

       government securities dealers in New York City of national standing 
       selected in good faith by Operator.

              "WEIGHTED AVERAGE LIFE TO MATURITY" -- with respect to the Prepaid
       Cash Flows, as at the payment or prepayment date for the determination of
       the Treasury Rate, the number of years obtained by dividing the then
       Remaining Dollar-years of such Prepaid Cash Flows by the principal amount
       of Notes then being paid or prepaid.  The term "REMAINING DOLLAR-YEARS"
       of the Prepaid Cash Flows means the product obtained by (x) multiplying
       (A)  the principal portion of each Prepaid Cash Flow (including the
       payment at final maturity), by (B)  the number of years (calculated to
       the nearest one-twelfth) between the time of determination and the date
       of such Prepaid Cash Flow, and (y) totaling all the products obtained in
       the computations described in clause (x).

       2.16   SPECIAL RIGHTS OF HOLDERS.  Notwithstanding any provision to the
contrary in this Agreement, the Indenture or the Notes relating to the manner
and place of payment, all amounts payable to a Holder with respect to any Notes
held by such Holder or a nominee for such Holder shall be paid by Indenture
Trustee to such Holder (without any presentment thereof and without any notation
of the payment being made thereon) by check, duly mailed, by first-class mail,
postage prepaid, or delivered to such Holder at the address for payments for
such Holder or, if a wire transfer to a bank account is designated in Schedule 1
to the Participation Agreement or in a written notice from such Holder to
Nonaffiliated Partner Trustee and Indenture Trustee, by wire transfer of
immediately available funds to the bank so designated for credit to the account
and marked for attention as so designated so long as such bank has facilities
for the receipt of a wire transfer, or in any other manner or to any other
address in the United States as may be designated by such Holder in a written
notice from such Holder to Nonaffiliated Partner Trustee and Indenture Trustee.
In the case of any wire transfer, Indenture Trustee will transfer funds from the
office of Indenture Trustee not later than 1:00 p.m. New York time on the date
any payment or prepayment of principal, Premium, if any, or interest on the
Notes is due if funds therefor have been received by Indenture Trustee in cash
or in solvent credits acceptable to it by 11:00 a.m., New York time, or if not
so received by such time, Indenture Trustee shall transfer such funds promptly
upon its receipt of such cash or solvent credits.  Each Holder agrees that, if
such Holder shall sell or transfer any Notes, such Holder will notify Indenture
Trustee of the name and address of the transferee and such Holder will, before
the delivery 

                                     -22-

of such Notes, make a notation on such Notes of the date to which interest 
has been paid thereon and of the amount of any payments or prepayments made 
on account of the principal thereof.

other Person together with any other amount received by Indenture Trustee 
with respect to interest on Priority Distributions not made on the relevant

effect:

              (a)    MODIFICATIONS.  Operator has the obligation, or the 
right, to make certain Modifications to the Units.  Any Optional Modification

Modifications which are not Required Modifications.

              (b)    SUBSTITUTION OF UNITS.  Upon the occurrence of (y) an 
Event of Loss, or (z) an optional substitution of a Unit pursuant to Section

shall reasonably request and as shall be reasonably acceptable to Indenture 
Trustee in order to make clear upon public records that such Lien with 
respect to such replaced Unit has been released under the laws of the

SPECIAL P.O. DATE.

              (a)    If an Event of Loss occurs with respect to a Unit and 
such Unit is not replaced pursuant to Section 5.12 of the Participation 
Agreement, the principal on each Outstanding Note shall be prepaid in part, 
together with interest on the principal so prepaid, at a Prepayment Price 
equal to the sum of (1)  as to principal thereof, an amount equal to the 
product obtained by multiplying the aggregate Current Principal Amount of 
each Outstanding Note as of the Prepayment Date (after deducting therefrom 
the related scheduled principal payment, if any, due and paid to Indenture 
Trustee on the Prepayment Date) by a fraction, the numerator of which shall 
be the Equipment Value of such Unit and the denominator of which shall be the 
Equipment Value of the Units then subject to the Lien of this Indenture 
immediately prior to such Prepayment Date, plus (2)  as to interest, the 
aggregate amount of interest accrued and unpaid in respect of the principal

Each prepayment made pursuant to subclause (1)  of this clause shall be (A) 
applied to the prepayment of such Notes being prepaid so that each of the 
remaining installments of principal of each such Note shall be reduced in the 
proportion that the principal amount of the prepayment bears to the unpaid 
principal amount of such Notes immediately before the prepayment and (B)  
made ratably over the Notes, without preference, priority or distinction of 
any one such Note over any other.  The Prepayment Date for Notes to be

Trustee has not given such notice and Partnership has not withdrawn its 
notice as provided in Section 5.16 of the Participation Agreement, principal 
on each Outstanding Note shall be prepaid in part, together with interest on 
the principal so prepaid at a Prepayment Price equal to the sum of (1) as to

Current Principal Amount of each Outstanding Note as of the Prepayment Date 
(after deducting therefrom the related scheduled principal payment, if any, 
due and paid to Indenture Trustee on the Prepayment Date) by a fraction, the 
numerator of which shall be the Equipment Value of such Unit or Units and the 
denominator of which shall be the Equipment Value of the Units then subject 
to the Lien of this Indenture immediately before such Prepayment Date, plus 
(2)  as to interest, the aggregate amount of interest accrued and unpaid in

application of any Priority Distribution paid to Indenture Trustee on or 
before the date of such prepayment, plus (3)  the Premium.  Each prepayment 
made pursuant to subclause (1) of this clause (b) shall be (A) applied to the 
prepayment of such Notes being prepaid so that each of the remaining 
installments of principal of each such Note shall be reduced in the 
proportion that the principal amount of the prepayment bears to the unpaid 
principal amount of such Notes in the aggregate immediately prior to the 
prepayment and (B) made ratably over the Notes, without preference, priority 
or distinction of any one such Note over any other.  The Prepayment Date for 
Notes to be prepaid pursuant to this Section 6.1(b) shall be the Payment Date 
that occurs on the Reduction Date.

              (c)    Upon (i) the election of General Partner or its designee to
exercise its fixed price purchase option pursuant to Section 9.1 or 9.4 of the
Partnership Agreement or (ii) the election of the General Partner to prepay the
Outstanding Notes on the ET Date or the Special P.O. Date, as the case may be,
notwithstanding that the General Partner or its designee has not elected to
exercise the ET Right, the Outstanding Notes shall be prepaid at a Prepayment
Price equal to the sum of (1) Current Principal Amount thereof, plus (2) accrued
but unpaid interest thereon to, but not including, the applicable Prepayment
Date, plus (3) if such fixed price purchase option is exercised on the Special
P.O. Date (but not otherwise) the Premium, plus (4) any other accrued and unpaid
Secured Obligations, if any.  The Prepayment Date for Notes to be prepaid
pursuant to this Section 6.1(c) shall be the Special P.O. Date or the ET Date,

paid within five Business Days after the same becomes due and payable;

              (b)    the existence of a BJ Event of Default;

Participation Agreement or the Trust Agreement, and any such default 
continues unremedied for 30 days after Nonaffiliated Partner Trustee and 
Beneficiaries receive notice thereof from Indenture Trustee specifying the 
default and demanding that the same be remedied; except that, if such failure 
is capable of being remedied and such remedy does not involve the payment of 
money alone, no such failure shall constitute an Indenture Event of Default 
hereunder while Nonaffiliated Partner Trustee (in its individual capacity or 
as Nonaffiliated Partner Trustee)or any Beneficiary is diligently proceeding 
to remedy such failure, but in no event shall such failure continue 
unremedied for a period of the lesser of 90 days from the date of such notice 
and the number of days remaining in the Transaction Term;

              (d)    any representation or warranty made by Nonaffiliated 
Partner Trustee (in its individual capacity or as Nonaffiliated Partner 
Trustee) herein, or by Nonaffiliated Partner Trustee or any Beneficiary in

any Beneficiary and, if instituted against Nonaffiliated Partner Trustee, the 
Trust Estate or any Beneficiary is allowed against Nonaffiliated Partner

Nonaffiliated Partner Trustee, Partnership and each Beneficiary, may, and upon
written request of a Majority In Interest of Holders shall, declare the
principal of all the Notes to be due and payable; except that the principal of
all Notes, together with accrued interest thereon from the date in respect of
which interest was last paid hereunder to the date payment of such principal has
been made, and all other accrued and unpaid Secured Obligations will
automatically become due and payable without any action of Indenture Trustee or
the Holders in the case of an Indenture Event of Default under Section 8.1(e),
(f) or (g), unless such Indenture Event of Default with respect to a Beneficiary
is remedied or the defaulting Beneficiary transfers its Beneficial Interest
pursuant to Section 8.3(e)(i)(4).  Upon such declaration, the principal of all
Notes, together with accrued interest thereon from the date in respect of which
interest was last paid hereunder to the date payment of such principal has been
made and all other accrued and unpaid Secured Obligations shall be immediately
due and payable as a result of such declaration or automatic acceleration.  At
any time after such declaration or automatic acceleration, as the case may be,
and before the sale or disposition of the Indenture Estate, a Majority In
Interest of Holders, by written notice to Indenture Trustee, Nonaffiliated
Partner Trustee, Partnership and each Beneficiary, may rescind such a
declaration or automatic acceleration, as the case may be, and thereby annul its
consequences if (a)  an amount sufficient to pay all principal of 

                                     -38-

<PAGE>

and interest (including interest at the Late Rate on overdue payments) on 
such Notes, to the extent each such amount is due or past due without regard 
to the acceleration hereof, if any, in respect of the Outstanding Notes and 
all other sums then due and payable to Indenture Trustee has been deposited 
with Indenture Trustee, (b) the rescission would not conflict with any 
judgment or decree and (c)  all existing Indenture Defaults and Indenture 
Events of Default under this Indenture are cured or waived except nonpayment 
of principal of, or interest on, the Notes which have become due solely 
because of such acceleration.  No such rescission shall affect any subsequent 
default or impair any right consequent thereon.

       8.3    OTHER REMEDIES AVAILABLE TO INDENTURE TRUSTEE.

              (a)    If an Indenture Event of Default exists, then and in 
every such case Indenture Trustee, as trustee of an express trust and as 
assignee hereunder of Nonaffiliated Partner Trustee's Partnership Interest or 
as holder of a security interest in the Units or otherwise, may, and when 
required pursuant to Section 9 shall, exercise (subject to the following

and all Persons claiming under any of them wholly or partly therefrom.  
Notwithstanding any other provision of this Indenture or any other of the 
Basic Documents to the contrary, Indenture Trustee shall not be entitled 
pursuant to Section 8.3(b) or otherwise to sell any of the Partnership 
Indenture Estate or exercise other remedies against the Partnership Indenture 
Estate or to exercise BJ Remedies (as defined below) until such time, if any, 
as a BJ Event of Default exists. Notwithstanding any other provision of this 
Indenture or any other of the Basic Documents, Indenture Trustee shall not be 
entitled to exercise any remedy hereunder as a result of an Indenture Event 
of Default that arises solely by reason of one or more events or 
circumstances that constitute a BJ Event of Default unless Indenture Trustee 
as security assignee of Nonaffiliated Partner Trustee declares the O&M 
Agreement to be in default and simultaneously, to the extent it is then 
entitled to do so hereunder and under the Partnership

otherwise prevented by operation of law from exercising such BJ Remedies, it 
shall in any event refrain from so foreclosing or otherwise exercising BJ 
Remedies hereunder (i) for 180 days after the commencement of such stay or 
other circumstances preventing the exercise of BJ Remedies or (ii) if 
Guarantor or an Affiliate of Guarantor with court approval assumes (and is 
performing the obligations of each Bankrupt BJ Entity under) the Basic 
Documents to which each Bankrupt BJ Entity is a party in accordance with 
Section 365 of the Bankruptcy Code and, if an Affiliate of Guarantor so 
assumes, Guarantor remains liable for all its obligations under the Guaranty 
to the same extent as if such assumption had not occurred.

              (b)    Subject to Sections 8.3(a), 8.3(e) and 8.3(f), if an
Indenture Event of Default exists, Indenture Trustee may, if at the time such
action is lawful and subject to compliance with any mandatory legal
requirements, either with or without taking possession, and either before or
after taking possession, and without instituting any legal proceedings
whatsoever, and having first given notice of such action by registered mail to
Nonaffiliated Partner Trustee, Partnership and each Beneficiary once at least 15
days before the date of such action, and any other notice required by law, sell
and dispose of the Indenture Estate, or any part thereof, or interest therein,
at a private sale or sales or a public auction to the highest bidder, in each
case, in one lot as an entirety or in separate lots, and either for cash or on
credit and on such terms as Indenture Trustee may determine, and at any place
(whether or not it is the location of the Indenture Estate or any part thereof)
and time designated in the notice above referred to.  Notwithstanding any
provision herein or in any other Basic Document to the contrary, Indenture
Trustee shall not sell any of the Partnership Indenture Estate or exercise other
remedies against the Partnership Indenture Estate or exercise BJ Remedies unless
a BJ Event of Default exists.  Notwithstanding any provision herein to the
contrary or in any other Basic Document, Indenture Trustee shall not sell any of
the Indenture Estate or exercise other remedies against the Indenture Estate
seeking to deprive Beneficiaries of their interest therein as a result of an
Indenture

Event of Default that arises solely by reason of one or more events or 
circumstances that constitute a BJ Event of Default unless a declaration of 
acceleration has been made pursuant to Section 8.2, Indenture Trustee as 
security assignee of Nonaffiliated Partner Trustee declares the O&M Agreement 
to be in default and Indenture Trustee is simultaneously exercising, to the 
extent it is then entitled to do so hereunder and under the Partnership 
Agreement, the Participation Agreement and the O&M Agreement and is not then 
stayed or otherwise prevented from doing so by operation of law, one or more 
BJ Remedies; and no private sale may be made to BJ USA or any of its 
Affiliates; except, that if Indenture Trustee is so stayed or otherwise 
prevented by operation of law from exercising such BJ Remedies, it shall in 
any event refrain from so foreclosing or otherwise exercising remedies 
hereunder (i) for 180 days after the commencement of such stay or other 
circumstances preventing the exercise of BJ Remedies or (ii) if Guarantor or 
an Affiliate of Guarantor with court approval assumes (and is performing the 
obligations of each Bankrupt BJ Entity under) the Basic Documents to which 
each Bankrupt BJ Entity is a party in accordance with Section 365 of the 
Bankruptcy Code and, if an Affiliate of Guarantor so assumes, Guarantor 
remains liable for all its obligations under the Guaranty as if such 
assumption had not occurred.  Any such sale or sales may be adjourned from 
time to time by announcement at the time and place appointed for such sale or 
sales, or for any such adjourned sale or sales, without further notice, and 
Indenture Trustee and any Holder may bid and become the purchaser at any such 
sale. Indenture Trustee may exercise such right without possession or 
production of the Notes or proof of ownership thereof, and as representative 
of Holders may exercise such right without notice to Holders or including 
Holders as parties to any suit or proceeding relating to foreclosure of any 
property in the Indenture Estate. Nonaffiliated Partner Trustee and 
Partnership each hereby irrevocably constitutes Indenture Trustee the true 
and lawful attorney-in-fact of Nonaffiliated Partner Trustee (in the name of 
Nonaffiliated Partner Trustee or otherwise) and Partnership (in the name of 
Partnership or otherwise), as the case may be, for the purpose of 
effectuating any sale, assignment, transfer or delivery upon enforcement of 
the Lien created under this Indenture, whether pursuant to foreclosure or 
power of sale or otherwise, to execute and deliver all such bills of sale, 
assignments and other instruments as Indenture Trustee may consider necessary 
or appropriate, with full power of substitution, Nonaffiliated Partner 
Trustee and Partnership each hereby ratifying and confirming all that such 
attorney or any substitute shall lawfully do by virtue hereof.  Nevertheless, 
if so requested by Indenture Trustee or any purchaser, Nonaffiliated Partner 
Trustee 

                                     -41-

<PAGE>

and Partnership each shall ratify and confirm any such sale, assignment, 
transfer or delivery, by executing and delivering to Indenture Trustee or 
such purchaser all bills of sale, assignments, releases and other proper 
instruments to effect such ratification and confirmation as may be designated 
in any such request.

              (c)    Subject to Sections 8.3(a), 8.3(e) and 8.3(f), if an
Indenture Event of Default exists, Nonaffiliated Partner Trustee or Partnership,
or both, shall, at the request of Indenture Trustee upon enforcement of the Lien
created under this Indenture, promptly execute and deliver to Indenture Trustee
such instruments of title or other documents as Indenture Trustee may deem
necessary or advisable to enable Indenture Trustee or an agent or representative
designated by Indenture Trustee, at such time and place or places as Indenture
Trustee may specify, to obtain possession of all or any part of the Indenture
Estate.  If Nonaffiliated Partner Trustee or Partnership for any reason fails to
execute and deliver such instruments and documents after such request by
Indenture Trustee, Indenture Trustee shall be entitled to a judgment for
specific performance of the covenants contained in the foregoing sentence,
conferring upon Indenture Trustee the right to immediate possession and
requiring Nonaffiliated Partner Trustee or Partnership, as the case may be, to
execute and deliver such instruments and documents to Indenture Trustee.
Subject to Sections 8.3(a), 8.3(e) and 8.3(f), Indenture Trustee shall also be
entitled to pursue all or any part of the Indenture Estate wherever it may be
found and may enter any of the premises of Nonaffiliated Partner Trustee or
Partnership or any other Person wherever the Indenture Estate may be or be
supposed to be and search for the Indenture Estate and take possession of any
item of the Indenture Estate pursuant to this Section 8.3(c).  Subject to
Sections 8.3(a), 8.3(e) and 8.3(f), Indenture Trustee may, from time to time, at
the expense of the Indenture Estate, make all such expenditures for maintenance,
insurance, repairs, replacements, alterations, additions and improvements to and
of the Indenture Estate, as it may deem proper.  In each such case, Indenture
Trustee shall have the right to use, operate, store, lease, control or manage
the Indenture Estate and to exercise all rights and powers of Nonaffiliated
Partner Trustee or Partnership relating to the Indenture Estate as Indenture
Trustee shall deem appropriate, including the right to enter into any and all
such agreements with respect to the use, operation, storage, leasing, control or
management of the Indenture Estate or any part thereof; and Indenture Trustee
shall be entitled to collect and receive directly all tolls, rents, payments,
distributions (including Priority Distributions, Supplemental Priority
Distributions and Special

revenues and other income of the Indenture Estate and every part thereof, 
without prejudice, however, to the right of Indenture Trustee under any 
provision of this Indenture to collect and receive cash held by, or required 
to be deposited with, Indenture Trustee hereunder.  In accordance with the 
terms of this Section 8.3(c), such tolls, rents, payments, distributions 
(including Priority Distributions, Supplemental Priority Distributions and 
Special Distributions other than Excepted Property), issues, profits, 
products, revenues and other income shall be applied to pay the expenses of 
using, operating, storing, leasing, controlling or managing the Indenture 
Estate, and of all maintenance, insurance, repairs, replacements, 
alterations, additions and improvements, and to make all payments which 
Indenture Trustee may be required or may elect to make, if any, for taxes, 
assessments, insurance or other proper charges upon the Indenture Estate or 
any part thereof (including the employment of engineers and accountants to 
examine, inspect and make reports upon the properties and books and records 
of Nonaffiliated Partner Trustee and Partnership) and all other payments 
which Indenture Trustee may be required or authorized to make under any 
provision of this Indenture, including this Section 8.3(c), as well as just 
and reasonable compensation for the services of Indenture Trustee, and of all 
persons properly engaged and employed by Indenture Trustee.

              If a BJ Event of Default exists and Indenture Trustee obtains 
possession of or title to the Units, Indenture Trustee shall not be obligated 
to use or operate the Units or cause the Units to be used or operated 
directly or indirectly by itself or through agents or other representatives 
or to lease, license or otherwise permit or provide for the use or operation 
of the Units by any other Person.

              (d)    Subject to Sections 8.3(a), 8.3(e) and 8.3(f), Indenture 
Trustee may proceed to protect and enforce this Indenture and the Notes by 
suit or suits or proceedings in equity, at law or in bankruptcy, and whether 
for the specific performance of any covenant or agreement herein contained or 
in execution or aid of any power herein granted, or for foreclosure 
hereunder, or for the appointment of a receiver or receivers for the 
Indenture Estate or any part thereof, or for the recovery of judgment for the 
indebtedness secured by the Lien created under this Indenture or for the 
enforcement of any other proper, legal or equitable remedy available under 
applicable law.

Priority Distribution distributable under the Partnership Agreement at least ten
Business Days after the Distribution Date therefor, Nonaffiliated Partner
Trustee or any Beneficiary, without the consent of Indenture Trustee or any
Holder but subject to Section 8.3(e)(i)(5), may, within the time period
specified in clause (4) below, pay to Indenture Trustee for application in
accordance with Section 3.3, a sum equal to the amount of all (but not less than
all) principal and interest (other than by acceleration) then due and payable on
the Outstanding Notes, together with any interest on account of such Priority
Distribution not being made on the Distribution Date as provided in
Section 4.4(b) of the Partnership Agreement.

                     (2)    If Partnership or General Partner defaults in the

Participation Agreement, Guarantor defaults in the payment or performance of any
obligation under the Guaranty or the Participation Agreement, BJ USA defaults in

Indenture Trustee or any Holder, may, within the period specified in clause (4)
below, pay or perform such obligation on behalf of Partnership, General Partner,
Guarantor, BJ USA, Service Taker  or Operator or otherwise perform such
obligations on behalf of Partnership, General Partner, Guarantor, BJ USA,
Service Taker or Operator, without the necessity of giving any notice to
Partnership, General Partner, Guarantor, BJ USA, Service Taker or Operator, it
being understood and agreed that nothing herein contained shall be deemed or
construed to prohibit Nonaffiliated Partner Trustee or any Beneficiary from
exercising any such rights of Partnership before any such notice from Indenture
Trustee.

exists an Indenture Event of Default, (i)  any payment by Nonaffiliated Partner
Trustee or any Beneficiary pursuant to, and in compliance with, Section
8.3(e)(i)(1) shall, for the purposes of this Indenture, be deemed to remedy any
default by Partnership in making Priority Distributions theretofore
distributable and to remedy any default by Nonaffiliated Partner Trustee in the
payment of any amount due and payable under the Notes, in each case only if such
payment pursuant to Section 8.3(e)(i)(1) is in an amount sufficient to remedy
such default, and (ii) any payment or performance by Nonaffiliated Partner

connection therewith nor shall any claim of Nonaffiliated Partner Trustee or 
any Beneficiary against Partnership, General Partner, Guarantor, Operator or 
any other Person for the repayment thereof impair the prior right and 
security interest of Indenture Trustee in and to the Indenture Estate.

amount with respect to which Nonaffiliated Partner Trustee or any Beneficiary

or Supplemental Distribution not being distributed on the Distribution Date
therefor or interest on account of such other amount being overdue) and (2) with
respect to which Nonaffiliated Partner Trustee or any Beneficiary otherwise
effected such cure, and if Indenture Trustee thereafter receives such Priority
Distribution, Supplemental Priority Distribution or other amount and no other
Indenture Event of Default exists, then, notwithstanding the requirements of
Section 3.3, Indenture Trustee forthwith shall remit such Priority Distribution,
Supplemental Priority Distribution or other amount to Nonaffiliated Partner

General Partner, Partnership, Operator, Service Taker, BJ USA or Guarantor
pursuant to this Section 8.3(e)(ii) except by demanding of Partnership, General
Partner, Operator, Service Taker, BJ USA or Guarantor payment of such amount or
by proceeding by appropriate court action or actions, either at law or at
equity, to enforce performance by Partnership, General Partner, Operator,
Service Taker, BJ USA or Guarantor of the applicable covenants or recover

or (2) the Notes are automatically accelerated as provided for in Section 8.2,
or (3) one or more BJ Event(s) of Default exists for a period of 180 days or
more (and no Indenture Event of Default that does not arise solely from a BJ
Event of Default exists) and the Notes are not accelerated by Indenture Trustee
or the Holders during such period, Nonaffiliated Partner Trustee or a
Beneficiary may give notice to Indenture Trustee of Nonaffiliated Partner
Trustee's or a Beneficiary's intention to purchase, or cause to be purchased by
another Person designated by Nonaffiliated Partner Trustee (or prepay in lieu of
purchase), all of the Notes in accordance with this Section 8.3(e)(iii), which,
if a prepayment, shall be pursuant to Section 6.1(d).  Concurrently with such

Partnership Agreement) and (B) all amounts then due and payable to Indenture
Trustee pursuant to Section 9.5(a)(i), which funds shall be held by Indenture
Trustee as provided in Section 9.3.  Upon the receipt of such funds, Indenture
Trustee will terminate any proceedings then in progress.  In the event of a
purchase by a Beneficiary or Nonaffiliated Partner Trustee (or a designee) of
the Notes pursuant to this Section 8.3(e)(iii) and upon payment to Indenture
Trustee of the Prepayment Price calculated pursuant to this Section 8.3(e)(iii),
each Holder will be deemed to sell, assign, transfer and convey to such
Beneficiary or Nonaffiliated Partner Trustee or its designee (without recourse
or warranty of any kind except as to title to the Notes being conveyed free and
clear of Liens attributable to such Holder) all of the right, title and interest
of such Holder in and to the Indenture Estate, this Indenture and all Notes held
by such Holder.  The Registrar shall register the transfer of ownership of the
Notes into the name of Nonaffiliated Partner Trustee or its designee.

              (iv)   If a BJ Event of Default exists and before (1) acceleration
of the Notes and (2) the expiration of the 180-day


                                    -48-

period referred to in Section 8.3(e)(iii) (and no Indenture Event of Default 
that does not arise solely from a BJ Event of Default exists), Nonaffiliated 
Partner Trustee or any Beneficiary may give notice to Indenture Trustee of 
Nonaffiliated Partner Trustee's or Beneficiary's intention to purchase, or 
cause to be purchased by another Person designated by Nonaffiliated Partner 
Trustee (or prepay in lieu of purchase), all of the Notes in accordance with 
this Section 8.3(e)(iv), which, if a prepayment, shall be pursuant to Section 
6.1(e).  Concurrently with such notice, Nonaffiliated Partner Trustee or 
Beneficiary will deposit with Indenture Trustee, whether or not an Indenture 
Event of Default then exists, an amount sufficient to pay the Prepayment 
Price equal to the aggregate unpaid principal amount of all unpaid Notes then 
Outstanding, together with (A) accrued but unpaid interest thereon to the 
date of such receipt (as well as any interest on overdue principal and, to 
the extent permitted by applicable law, overdue interest calculated as 
provided in Section 4.4(b) of the Partnership Agreement), (B) the Premium, if 
any, as of the date of deposit and (C) all amounts then due and payable to 
Indenture Trustee pursuant to Section 9.5(a)(i), which funds shall be held by 
Indenture Trustee as provided in Section 9.3.  Upon the receipt of such 
funds, Indenture Trustee will terminate any proceedings then in progress.  In 
the event of a purchase by any Beneficiary or Nonaffiliated Partner Trustee 
of Notes pursuant to this Section 8.3(e)(iv) and upon payment to Indenture 
Trustee of the Prepayment Price calculated pursuant to this Section 
8.3(e)(iv), each Holder will be deemed to sell, assign, transfer and convey 
to Beneficiary or Nonaffiliated Partner Trustee or its designee (without 
recourse or warranty of any kind except as to title to the Notes being 
conveyed free and clear of Liens attributable to such Holder) all of the 
right, title and interest of such Holder in and to the Indenture Estate, this 
Indenture and all Notes held by such Holder.  The Registrar shall register 
the transfer of ownership of the Notes into the name of Nonaffiliated Partner 
Trustee or its designee.

              (f)    Notwithstanding any provision of this Indenture or any
other Basic Document to the contrary, as long as no BJ Event of Default exists,
neither Indenture Trustee nor Nonaffiliated Partner Trustee shall take any
action contrary to, or disturb, Service Taker's rights under the Services
Agreement, Operator's rights under the O&M Agreement or the rights of General
Partner and Affiliated Partner under the Partnership Agreement.

              (g)    Each and every right, power and remedy herein given to
Indenture Trustee specifically or otherwise in this Indenture shall be
cumulative and shall be in addition to every 


                                    -49-

<PAGE>

other right, power and remedy herein specifically given or now or hereafter 
existing at law, in equity or by statute, each and every right, power and 
remedy whether specifically herein given or otherwise existing may, subject 
to the limitations set forth herein, be exercised from time to time and as 
often in such order as may be deemed expedient by Indenture Trustee, and the 
exercise or the beginning of the exercise of any power or remedy shall not be 
construed to be a waiver of the right to exercise at the same time or 
thereafter any other right, power or remedy.  No delay or omission by 
Indenture Trustee or any Holder in the exercise of any right, remedy or power 
or in pursuing any remedy shall impair any such right, power or remedy or be 
construed to be a waiver of any default on the part of Nonaffiliated Partner 
Trustee, Partnership, General Partner, Guarantor, Operator or Service Taker 
or to be an acquiescence therein.  The giving, taking or enforcement of any 
other additional security, collateral or guaranty for the payment and 
performance of Secured Obligations shall not operate to impair, affect, waive 
or prejudice the Lien of this Indenture or any rights, powers or remedies 
hereunder.  Neither Indenture Trustee nor any Holder shall be required to 
look to any additional security, collateral or guaranty, or exhaust any 
remedies with respect thereto, before exercising remedies hereunder or under 
the Partnership Agreement, Participation Agreement, the Services Agreement, 
the Guaranty, or the O&M Agreement in accordance with the terms hereof or 
thereof.

extent now or at any time hereafter enforceable under applicable law,
Nonaffiliated Partner Trustee and Partnership each covenants that it will not
(i)  at any time insist upon or plead, or in any manner whatsoever claim or take
any benefit or advantage of, any stay or extension law now or at any time
hereafter in force, nor claim, take or insist upon any benefit or advantage of
or from any law now or hereafter in force providing for the valuation or
appraisal of the Indenture Estate or any part thereof before any sale or sales
thereof to be made pursuant hereto, or to the decree, judgment or order of any
court of competent jurisdiction; nor (ii)  after such sale or sales, claim or
exercise any right under any statute now or hereafter made or enacted by any
state or otherwise to redeem the property so sold or any part thereof, and to
the extent now or at any time hereafter enforceable under applicable law hereby
expressly waives for itself and on behalf of each and every Person, except
decree or judgment creditors of Nonaffiliated Partner Trustee acquiring any
interest in or title to the Indenture Estate or any part thereof subsequent to
the date of this Indenture, all benefit and advantage of any


                                    -50-

<PAGE>

such law or laws, and covenants that it will not invoke or utilize any such 
law or laws or otherwise hinder, delay or impede the execution of any power 
herein granted and delegated to Indenture Trustee, but will suffer and permit 
the execution of every such power as though no such law or laws had been made 
or enacted. Nothing in this Section 8.4 shall be deemed to be a waiver by 
Nonaffiliated Partner Trustee or Partnership of its rights under the 
exception to Section 8.3(a) and under Section 8.3(e).

       8.5    WAIVER OF EXISTING DEFAULTS.  A Majority In Interest by notice to

method and place of conducting any proceeding for any remedy available to
Indenture Trustee or exercising any trust or power conferred on it by this
Indenture.  However, Indenture Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that is unduly prejudicial to the rights
of the Holders so affected, or that would subject Indenture Trustee to personal
liability.

       8.7    LIMITATION ON SUITS BY HOLDERS.  A Holder may pursue a remedy
under this Indenture or under a Note only if:

              (a)    the Holder gives to Indenture Trustee written notice of a
continuing Indenture Event of Default under this Indenture;

              (b)    a Majority In Interest make a written request to Indenture

or which may be, incurred by Indenture Trustee in pursuing the remedy;

              (d)    Indenture Trustee does not comply with the request within

              (e)    during such 60-day period, a Majority In Interest does not
give Indenture Trustee a direction inconsistent with the request.

              A Holder may not use this Indenture to prejudice the rights of

consent of such Holder.

file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of Indenture Trustee and of the Holders
allowed in any judicial proceedings relating to Partnership, Guarantor, Service
Taker, Operator or Nonaffiliated Partner Trustee, their respective creditors, or

all Taxes saved by such Tax Indemnitee that would not have been saved but for
the payment or accrual of the obligation to pay such amount (or the payment or
accrual of the obligation to pay amounts by reason of a "gross-up" provision) is
equal to the amount to be paid under the applicable Basic Document.  All
computations for the purposes hereof shall be based on the highest applicable
tax rates in effect in the applicable jurisdiction on the date payment is made
or accrued, as the case may be.

such property or other consideration at the time of contribution as determined

       without limitation, in this definition of BJ Event of Default) or in 
       any of the Basic Documents, none of the foregoing events or

Value in a written appraisal that is in compliance with the "Uniform Standards

as the case may be, shall be zero with respect to any Unit if Nonaffiliated
Partner Trustee theretofore has not been able to recover possession of such Unit
in accordance with the terms of Section 15.1(b) of the O&M Agreement.
