Trustee a surety bond in favor of the Credit Enhancer, in the amount of $3
million. Such surety bond serves to secure the obligation of Realty to make
loans under Section 3.1(b)(iii) of this Agreement.

                    (e)  To secure its obligation to make Capital Contributions
under Section 3.1(b)(ii) of this Agreement, on the date hereof, Project Capital
shall cause to be delivered to the Trustee an irrevocable letter of credit in
favor of the Trustee, satisfactory to the Credit Enhancer, in the amount of
$3,500,000. The amount of such letter of credit shall be reduced by the amount
of the aggregate Capital Contributions made by Project Capital under Section
3.1(b)(ii) of this Agreement.

                                       16

To secure its obligation to make loans under Section 3.1(b)(iii) of this
Agreement, Project Capital shall cause to be delivered to the Trustee promptly
after the date hereof a letter of credit in favor of the Credit Enhancer, in the
amount of $1,000,000.

                    (f)  If the General Partner reasonably determines that the
Partnership, after demanding payment from all parties obligated either to lend
funds to the Partnership or to repay any debt or obligation to the Partnership,
in whole or in part, will be unable to make a payment of principal or interest,
as the case may be, on a timely basis with respect to the Assumed Debt, the
General Partner may, in its sole discretion, require that Project Capital make
additional Capital Contributions, in an amount equal to the lesser of (i) the
aggregate amount required to make such principal or interest payment and (ii)
the maximum amount then payable by Project Capital in respect of its obligations
under Section 3.3 and the Assumption Agreement, in order to enable the
Partnership to make payments of principal and interest pursuant to the terms of
the Loan Agreement. The General Partner shall use its best efforts to demand
such additional Capital Contributions at the earliest practicable time in
advance of the date such payment, with respect to the indebtedness evidenced by
the Loan Agreement, is required to be made. Upon the demand of the General
Partner, Project Capital shall make such Capital Contributions 15 days prior to
the date such payment is due, unless demand is made less than 15 days prior to
the due date, in which case such Capital Contributions shall be made as soon as
practicable. If Project Capital shall pay to the Trustee on behalf of the City
any amount pursuant to the Assumption Agreement, then the amount of the
additional Capital Contribution which may be demanded by the General Partner
from Project Capital shall be reduced on a dollar-for-dollar basis by any amount
so paid, and any such payments under the Assumption Agreement shall be deemed to
be additional Capital Contributions under this Section 3.1(f) and shall increase
the Capital Account of Project Capital. As between the General Partner and
Project Capital, Project Capital shall be liable for any repayments of
borrowings pursuant to the Loan Agreement but only to the extent of their
obligation under the Assumption Agreement, and Project Capital shall have no
right of contribution from the General Partner or the Partnership in the event
that Project Capital is required to make payment under this Section 3.l(f) or
the Assumption

                                       17
<Page>

Agreement. The obligation of Project Capital to make additional Capital
Contributions under this Section 3.1(f) shall terminate at such time as its
obligation to make payments pursuant to the Assumption Agreement terminates;
PROVIDED, HOWEVER, that such obligation to make additional Capital Contributions
shall continue to be effective, to the same extent provided for in the
Assumption Agreement.

                    (g)  If a Limited Partner shall fail to make any Capital
Contribution payment or loan within 30 days after notice from any Partner that
the payment is due, and the Trustee is unable to draw on the letter of credit or
surety bond securing the obligation to make such Capital Contribution or loan,
the Limited Partner shall be in default upon the delivery of a notice of such
failure by the General Partner to the defaulting Limited Partner and each other
Partner and, upon such default, interest on the unpaid balance of the Capital
Contribution amount then due and payable shall accrue at the rate equal to the
prime rate posted from time to time by Citibank, N.A., New York, New York, plus
two percent (2%) from the date when said payment was due until the date paid.
During the period of any such default, (i) the General Partner may commence
legal proceedings against the defaulting Limited Partner to compel payment of
all amounts due as a Capital Contribution, and all costs and expenses of
collection incurred by the Partnership (including reasonable attorney's fees);
(ii) the defaulting Limited Partner shall not be entitled to any distributions
or allocations of profits, losses or other Partnership items; and (iii) each
non-defaulting Limited Partner shall have, on a pro rata basis among all such
non-defaulting Limited Partners, the right (but not the obligation), (1) to pay
all of such amounts due as a Capital Contribution and shall acquire, to the
extent so paid, an increased proportionate interest in the Limited Partnership
interests in the Partnership, and (2) to make such loans.

                    (h)  In the event of default pursuant to Section 3.l(g) of
this Agreement, all unpaid Capital Contributions of the defaulting Limited
Partner may become immediately due and payable at the option of the General
Partner and the interest in the Partnership of the defaulting Limited Partner
shall be subject to Transfer as provided herein without any consent of the
defaulting Limited Partner. The General Partner may, subject

                                       18
<Page>

to the provisions of this Section 3.1(h), sell all or any part of the defaulting
Limited Partner's interest for the Partnership's benefit to any Person on the
best terms reasonably obtainable; provided that prior to consummating any such
sale (including, without limitation, any sale to any Partner) each
non-defaulting Limited Partner shall have the right (but not the obligation),
upon 15 days' prior written notice, to acquire at such price its pro rata share
thereof based on the interest of all non-defaulting Limited Partners in the
Partnership, and of any such interest which any such Limited Partner fails to so
acquire. If the interest is sold at a price in excess of the defaulting Limited
Partner's remaining liabilities and costs, the General Partner shall remit the
excess to the defaulting Limited Partner. The defaulting Limited Partner shall
be liable for any and all costs of sale of the interest, whether the interest is
actually sold or not. If the interest is sold at a price less than the
defaulting Limited Partner's remaining liabilities and costs, the defaulting
Limited Partner shall be immediately liable for the difference; PROVIDED,
HOWEVER, that the defaulting Limited Partner's obligations hereunder shall be
relieved to the extent of payments actually made in the defaulting Limited
Partner's stead by any purchaser of the defaulting Limited Partner's interest.

                    (i)  Any Person purchasing the interest of a defaulting
Limited Partner pursuant to this Section 3.1 shall become a Substitute Limited
Partner upon compliance with the provisions of Section 10.3; PROVIDED, HOWEVER,
that if a nondefaulting Limited Partner acquires the interest of the defaulting
Limited Partner, such nondefaulting Limited Partner may become a Substitute
Limited Partner without compliance with the provisions of Sections 10.3(a) and
(d) of this Agreement.

          3.2       ADDITIONAL CAPITAL CONTRIBUTIONS. Except as hereinabove set
forth, no Partner shall be required to make any additional Capital Contributions
to the Partnership without the Consent of all the Partners.

          3.3       ASSUMPTION OF PARTNERSHIP LIABILITIES. Project Capital shall
assume and become personally liable for the liability of the Partnership arising
from the

                                       19
<Page>

Loan Agreement as provided in and limited by the terms and conditions set forth
in the Assumption Agreement.

          3.4       NO INTEREST ON CAPITAL. No interest shall be paid to any
Partner on all or a portion of a Capital Contribution or on a balance in its
Capital Account.

          3.5       CAPITAL WITHDRAWALS AND RETURNS. No Partner shall have the
right to withdraw or reduce its contributions to the capital of the Partnership
except in accordance with this Agreement pursuant to a Transfer of its
partnership interest or otherwise. Except as otherwise provided herein, no
Partner shall have the right to demand or receive property, other than cash, in
return for its Capital Contribution or have priority over another Partner,
either as to the return of contribution of capital or as to profits, losses, or
distributions, or as to compensation by way of income.

          3.6       WAIVER OF PARTITION AND DISSOLUTION RIGHT. The Partners
hereby waive and forfeit all rights arising out of statute or operation of law
to seek, bring or maintain in any court an action for partition pertaining to
any asset of the Partnership, or an action seeking dissolution of the
Partnership, unless the General Partner has consented to such dissolution.

          3.7       CAPITAL ACCOUNTS. A Capital Account shall be maintained with
respect to each Partner in accordance with Federal income tax accounting
principles and Treasury Regulation Section 1.704-l(b). Except as otherwise
provided herein, each Capital Account shall be credited with the amount of the
cash contribution to the capital of the Partnership by such Partner, the fair
market value of property contributed to the Partnership by such Partner (net of
liabilities assumed with respect to such interest and liabilities to which such
contributed property is subject), the distributive share of Partnership income
and gain (or items thereof) as allocated to such Partner pursuant to Section
4.1, and the distributive share of income exempt from tax. Each Capital Account
shall be charged for the amount of any loss or deduction (or items thereof)
allocated to such Partner

                                       20
<Page>

pursuant to Section 4.1, the amount of all distributions in cash to such Partner
pursuant to this Agreement, the fair market value of property distributed to
such Partner (net of liabilities assumed with respect to such interest and
liabilities to which such distributed property is subject), and the distributive
share of expenditures of the Partnership described in Section 705(a)(2)(B) of
the Code (which share shall be determined in accordance with the allocable
interests in the Partnership). The following rules shall apply in maintaining
Capital Accounts with respect to interests in the Partnership:

                    (a)  A Partner who has more than one interest in the
Partnership shall have a single Capital Account that reflects all such
interests, regardless of the class of interests owned by such Partner (e.g.,
general or limited) and regardless of the time or manner in which such interests
were acquired.

                    (b)  For purposes of this Section 3.7, amounts described in
Section 709 of the Code (other than amounts with respect to which an election is
in effect under Section 709(b) of the Code) shall be treated as described in
Section 705(a)(2)(B) of the Code.

                    (c)  If property is distributed by the Partnership, Capital
Accounts shall be adjusted as though such property had been sold on the date of
such distribution for its then fair market value, and any gain or loss on such
sale had been allocated in accordance with Section 4.1.

                    (d)  If property is contributed to the Partnership, Capital
Accounts shall be adjusted in accordance with Treasury Regulation Section 1.704-
1(b)(2)(iv)(d)(3).

                    (e)  Capital Accounts shall be adjusted, in accordance with
Treasury Regulation Section 1.704-1(b)(2)(iv)(j), to reflect any adjustments to
the basis of Partnership property under Section 48(q) of the Code.

                                       21

ARTICLE 4.  PROFITS AND LOSSES.

          4.1       ALLOCATION OF PROFITS AND LOSSES.

                    (a)  Commencing on the date hereof and continuing up to the
fifth anniversary of the In-Service Date, all Partnership items of income, gain,
loss, deduction or credit, as determined for Federal income tax purposes, shall
be allocated as follows: 1 percent to the General Partner, 49.5 percent to
Realty, 33 percent to ENI, and 16.5 percent to Project Capital; PROVIDED,
HOWEVER, that losses shall be allocated first to Partners who have positive
Capital Account balances, and shall not be allocated to a Partner who has a
negative Capital Account balance when any other Partner has a positive Capital
Account balance.

                    (b)  For each year during the remaining term of the
Partnership:

                         (i)    Except as set forth in Section 4.1(d), the Net
Taxable Income of the Partnership shall be allocated (X) first, to those
Partners who have heretofore received aggregate distributions of Net Cash Flow
(including those made in the year of determination) in excess of the aggregate
net taxable income (excluding that of the year of determination) allocated to
them, which allocation shall be in proportion to such excess; and, (Y) then, the
balance (if any) to all Partners in accordance with the percentages in which
they share in Net Cash Flow in the year of determination; and

                         (ii)   The Net Tax Losses of the Partnership shall be
allocated (X) first, to those Partners who have heretofore been allocated
aggregate net taxable income (excluding that in the year of determination) in
excess of the aggregate distribution of Net Cash Flow (including that in the
year of determination) received by them, which allocation shall be in proportion
to such excess; and, (Y) then, the balance (if any) to all Partners in
accordance with their sharing percentages of Net Cash Flow in the year of
determination; PROVIDED, HOWEVER, that losses shall be allocated first to
Partners who have positive Capital Account balances and will not be allocated to
a Partner who has a negative Capital Account balance when any other Partner has
a positive Capital Account balance.

                                       22
<Page>

                    (c)  For purposes of Section 4.1(b) "aggregate net taxable
income" is the excess of the Net Taxable Income of the Partnership for prior
years previously allocated to a Partner over the Net Tax Losses of the
Partnership during such period previously allocated to such Partner.

                    (d)  Any gain attributable to the sale or Disposition,
financing or refinancing, of the Project shall be allocated as follows: first,
to any Partners with negative Capital Accounts, in an amount necessary to
restore their Capital Accounts to zero; then 10 percent to the General Partner,
45 percent to Realty, 30 percent to ENI and 15 percent to Project Capital.

          4.2       RESTORATION OF NEGATIVE CAPITAL ACCOUNTS. Except as may be
required by law, or in respect of any negative balance resulting from withdrawal
of capital or a distribution in contravention of this Agreement, at no time
during the term of the Partnership shall a Partner with a negative balance in
its Capital Account have any obligation to the Partnership or to another Partner
to restore such negative balance.

          4.3       PARTNERSHIP ADJUSTMENTS. In the event of the Transfer of all
or any part of the Partnership interest of a Partner or upon the death of a
Partner (if such Partner is a natural person), the Partnership shall elect to
adjust the basis of Partnership property. Any increase or decrease in the amount
of any item of income, gain, loss, deduction or credit attributable to an
adjustment to the basis of Partnership assets made pursuant to such election
under Sections 734, 743 and 754 of the Code, and pursuant to corresponding
provisions of applicable state and local income tax laws, shall be charged or
credited, as the case may be, to those Partners entitled thereto under such
laws. For purposes of the foregoing, Project Capital shall be deemed to have
joined the Partnership on June 1, 1986.

          4.4       ALLOCATIONS TO TRANSFERRED PARTNERSHIP INTERESTS. Profits,
gains, losses, deductions and credits allocated to a Partnership interest
assigned or reissued during a Fiscal Year shall be allocated to each Person who
was the holder of the Partnership interest

                                       23
<Page>

during such Fiscal Year, in proportion to the number of days that each such
holder was recognized as the owner of such Partnership interest during such
Fiscal Year or during an interim period in respect of which the books of the
Partnership shall be closed, as the case may be, or in any other manner
permitted by the Code and selected by the General Partner in accordance with
this Agreement, without regard to the results of Partnership operations or the
date, amount or recipient of any distributions which may have been made with
respect to such Partnership interest. The effective date of the assignment shall
be (a) in the case of a voluntary assignment, the actual date the assignment as
recorded on the books of the Partnership, or (b) in the case of involuntary
assignment, the date of the operative event; PROVIDED, HOWEVER, in the case of
the transfer of the partnership interest to Project Capital, June 1, 1986 shall
be the effective date of such transfer.

ARTICLE 5.  DISTRIBUTIONS.

          5.1       NET CASH FLOW. The Net Cash Flow of the Partnership (and any
reserves that may have been set aside and that are subsequently deemed available
for distribution by the General Partner) shall be distributed as follows: 10
percent to the General Partner, 45 percent to Realty, 30 percent to ENI and 15
percent to Project Capital, PROVIDED, HOWEVER that the Net Cash Flow of the
Partnership shall be distributed to Project Capital until the aggregate of the
amounts paid by Project Capital under the Assumption Agreement have been repaid
to Project Capital pursuant to this Section 5.1. Such distributions shall be
made at the end of each calendar quarter, except as otherwise required by the
Reimbursement Agreement, in which case distributions shall be made only in
accordance therewith.

          5.2       NET SALE OR REFINANCING PROCEEDS. Net Sale or Refinancing
Proceeds shall be distributed promptly upon receipt as follows: 10 percent to
the General Partner, 45 percent to Realty, 30 percent to ENI and 15 percent to
Project Capital.

                                       24
<Page>

          5.3       DISTRIBUTIONS IN KIND. During the existence of the
Partnership, no Partner shall be entitled to receive as distributions from the
Partnership any Partnership asset other than money. If upon termination and
liquidation of the Partnership, the General Partner determines that (a) an
immediate sale of part or all of the assets of the Partnership would cause undue
loss to the Partners, and (b) the assets of the Partnership would be readily
susceptible to division for distribution in kind to the Partners, then to that
extent the General Partner may distribute such assets to the Partners in kind.
For such purposes, the assets of the Partnership shall be valued at fair market
value at the time of distribution.

ARTICLE 6.  POWERS, RIGHTS AND DUTIES OF THE GENERAL PARTNER.

          6.1       MANAGEMENT.

                    (a)  The General Partner shall have exclusive management and
control of the business of the Partnership and all decisions regarding the
management and affairs of the Partnership shall be made by the General Partner.
The General Partner shall have all the rights and powers of a General Partner as
provided in the Act and as otherwise provided by law, and any action taken by
the General Partner shall constitute the act of and serve to bind the
Partnership. In dealing with the General Partner acting on behalf of the
Partnership, no Person shall be required to inquire into its authority to bind
the Partnership. Persons dealing with the Partnership are entitled to rely
conclusively upon the power and authority of the General Partner as set forth in
this Agreement.

                    (b)  The General Partner shall devote such time to the
Partnership business as it shall reasonably deem to be necessary to supervise
the Partnership's business and affairs in an efficient manner; but nothing
contained in this Agreement shall preclude the employment, at the expense of the
Partnership, of any agent or other third party to operate and manage all or any
portion of the property, business or operations of the Partnership, subject to
the control of the General Partner. Subject to Section 6.3 of this Agreement,
Affiliates of the General Partner may be employed by the Partnership to

                                       25
<Page>

perform any other services for the Partnership deemed reasonably necessary by
the General Partner, provided that the amount charged to the Partnership for
such services will not exceed the amounts which the Partnership would be
required to pay to independent parties for such services.

                    (c)  In furtherance of the purpose of the Partnership as set
forth in Section 2.4 of this Agreement, the General Partner is hereby granted
the right, power and authority to do on behalf of the Partnership all things
which, in its sole and reasonable judgment, are necessary, proper or desirable
to carry out its duties and responsibilities hereunder, including, but not
limited to, the following: from time to time to incur all reasonable
expenditures; to employ and dismiss from employment any and all employees,
agents, contractors, brokers, attorneys and accountants; to create, by grant or
otherwise, easements and servitudes; to borrow money on an unsecured basis; to
borrow money in any amount from any Person other than the General Partner,
including any Affiliates of the General Partner, on a recourse or nonrecourse
basis, and as security therefor to mortgage all or any part of the Partnership's
property; to renovate, alter, improve, repair, raze, replace or rebuild any
building or other improvement on all or any portion of any Partnership property
which is real estate; to purchase or acquire interests in real or personal
property; to obtain refinancings or replacements of any mortgages or other
security instruments related in any way to any Partnership property, and to
prepay in whole or in part, refinance, recast, modify, consolidate or extend any
of the terms of any indebtedness owed by the Partnership or affecting all or any
portion of any Partnership property; to do any and all of the foregoing at such
price or amount for cash, securities or other property and upon such terms as
the General Partner deems proper; to place record title to any of the
Partnership's property in its name or in the name of a nominee or a trustee for
the purpose of mortgage financing or any other convenience or benefit of the
Partnership; and to execute, acknowledge and deliver any and all contracts,
agreements or other instruments to effectuate any and all of the foregoing;
PROVIDED, HOWEVER, that the General Partner shall not, without the prior Consent
of ENI and Realty, (i) consent or agree to the substitution or replacement of
the Credit Enhancer by any other Person (except that such Consent shall not be
required if National

                                       26
<Page>

Westminster Bank PLC is substituted for the Credit Enhancer pursuant to Section
8.3(a) of the Reimbursement Agreement), (ii) contract for or otherwise agree to
the sale or mortgage of, or sell or grant a mortgage or security interest in,
the Project, other than to secure the Bonds, (iii) permit the Partnership to
issue any bonds, notes or other evidences of indebtedness in connection with any
offer, issuance or sale thereof to the public, other than the Bonds, or (iv)
create, incur, or assure any indebtedness for borrowed money except as permitted
by the Reimbursement Agreement and borrowings from Partners pursuant to this
Agreement. The General Partner shall serve as the Tax Matters Partner, as
defined in the Code, and cause the preparation of all tax and information
returns for the Partnership (including, but not limited to, Federal, state and
local income tax and information returns).

                    (d)  The General Partner shall not be required to manage the
Partnership as its sole and exclusive function, and it may have other business
interests and may engage in other activities in addition to those relating to
the Partnership. Neither the Partnership nor any Partner shall have any right by
virtue of this Agreement or the Partnership relationship created hereby in or to
such other ventures or activities or to the income or proceeds derived
therefrom, and the pursuit of such ventures shall not be deemed wrongful or
improper. No Partner nor any Affiliate of a Partner shall be obligated to
present any particular investment opportunity to the Partnership even if such
opportunity is of a character which, if presented to the Partnership, could be
taken by the Partnership, and each of them shall have the right to take for its
own account (individually or otherwise) or to recommend to others any such
particular investment opportunity.

                    (e)  No Partner shall intentionally take or cause to be
taken any action which constitutes a default under any contracts or agreements
to which the Partnership is a party, nor shall any Partner perform any act in
violation of any applicable law or regulation thereunder, including all
applicable Federal and state securities laws.

                                       27
<Page>

          6.2       FIDUCIARY DUTIES. The General Partner shall have the
fiduciary duty to conduct the affairs of the Partnership for the exclusive
benefit of the Partnership and to use all Partnership funds and assets in the
best interests of the Partnership. All funds of the Partnership (other than
those invested in Qualified Investments) shall be deposited in the name of the
Partnership in separate interest-bearing accounts in a bank or a savings and
loan association, and the General Partner shall have full authority on behalf of
the Partnership to adopt such resolutions as may be required by any such bank or
savings and loan association for the operation of such account, to make deposits
and withdrawals from such account, to make and execute the checks, drafts, notes
and other instruments representing funds of the Partnership in such account,
and to take any and all such other action as may be necessary or appropriate in
connection with the operation of such account. The General Partner may otherwise
invest the funds of the Partnership only in Qualified Investments.

          6.3       BUSINESS WITH AFFILIATES OR ASSOCIATES. The General Partner
shall not cause the Partnership to transact any business with the General
Partner, collectively or individually, or an Affiliate or Associate thereof,
for goods or services in connection with the conduct of the Partnership's
business, except that such transaction may be effected if the transaction is on
terms competitive with those that may be obtained from unaffiliated Persons.

          6.4       COMPENSATION. In consideration of the services to be
performed by the General Partner after the In-Service Date, the General Partner
shall be paid an annual Management Fee in the amount of $300,000. The Management
Fee shall be paid on the last day of each calendar quarter in arrears commencing
on the last day of the first calendar quarter following the In-Service Date and
continuing thereafter during the remaining term of the Partnership. The first
such payment shall be prorated according to the actual number of days between
the In-Service Date and the last day of the first full calendar quarter
following the In-Service Date.

                                       28
<Page>

          6.5       REIMBURSEMENT. The Partnership shall reimburse the General
Partner for the cost of goods, materials and services used for or by the
Partnership. The General Partner shall not be reimbursed by the Partnership for
any indirect expenses incurred in performing services for the Partnership, such
as officers' salaries, rent, utilities and other overhead items. The Partnership
shall, however, reimburse the General Partner for services which could be
performed directly for the Partnership by independent parties, such as legal,
accounting, duplicating and other similar services. Such amounts charged to the
Partnership shall not exceed the lesser of (a) the actual cost of such services
to the party providing them, or (b) the amount which the Partnership would be
required to pay to independent parties for comparable services. Each such
payment and reimbursement of expenses pursuant to this Section 6.5 shall be made
regardless of whether any distributions are made to the Limited Partner and
shall be in addition to the other payments or benefits described herein.

          6.6       ESTABLISHMENT OF RESERVES.

                    (a)  Upon the IDB Closing, the General Partner established
the Reserve Fund and such other funds as provided for by the Trust Indenture and
the Reimbursement Agreement and caused to be deposited or shall cause to be
deposited therein such amounts as are or may be required pursuant to the Loan
Agreement, the Trust Indenture and the Credit Facility. In the event the Trustee
and the Credit Enhancer no longer require the Partnership to maintain the
Reserve Fund or any such other funds as provided for by the Trust Indenture, the
amounts in such funds shall be applied first to repay loans made to the
Partnership by the Partners and then shall be distributed as set forth in
Section 5.1 of this Agreement.

                    (b)  Pursuant to the terms of this Agreement, the General
Partner may from time to time establish such reserves for the Partnership as it
in good faith deems reasonable and necessary. At such time as the General
Partner deems such reserves no longer necessary, they shall be applied first to
repay loans made to the Partnership by the Partners and then shall be
distributed as set forth in Section 5.1 of this Agreement.

ARTICLE 7.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE GENERAL PARTNER.

          7.1       REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE GENERAL

Partner shall be limited to the amount of its total Capital Contribution and

<Page>

permitted by law and extend to its successors and assigns, and the Transfer or
assignment of all or any part of the Partnership interest of such Partner;
PROVIDED, HOWEVER, that if the General Partner or any Limited Partner Transfers
all or any part of its respective Partnership interest, the foregoing power of
attorney of a Transferor Partner shall survive such Transfer only until such
time as the Transferee shall have been admitted to the Partnership as a
Substitute Partner and all required documents and instruments shall have been
duly executed, filed and recorded to effect such substitution.

ARTICLE 10. TRANSFER OF LIMITED PARTNERSHIP INTERESTS.

          10.1      NO UNPERMITTED TRANSFERS. The Limited Partners may not sell,
assign, Transfer or otherwise dispose of, or pledge, hypothecate or otherwise
encumber their interest in the Partnership or any part thereof in any way
whatsoever except as permitted in this Section 10, and any such sale,
assignment, Transfer, or other disposition, pledge, hypothecation or encumbrance
in violation of this Article 10 shall be null and void as against the
Partnership, except as otherwise provided by law.

          10.2      PERMITTED TRANSFERS. At any time and only as permitted under
the Reimbursement Agreement, a Limited Partner may sell, Transfer or otherwise
assign all or any part of its respective interest in the Partnership (but only
if the Transferor shall not then be in material default under this Agreement),
provided that:

                    (a)  Any assignee or Transferee shall take such interest
subject to the terms, provisions and conditions of this Agreement and shall
acknowledge its acceptance of this Agreement by executing and delivering to the
remaining Partner(s) an instrument in form satisfactory to said Partner(s)
whereby such assignee or Transferee assumes and agrees to be bound by all the
terms, provisions and conditions hereof and to become, in the place of or in
addition to the transferring Limited Partner, a Partner for all purposes herein
(in connection with such assignee's or Transferee's assumption of obligations
hereunder, such assignee or Transferee shall be entitled to the benefit of any
limitation upon the liability

                                       36
<Page>

of the Transferor hereunder). Each Partner agrees to give the assignor and the
assignor's proposed assignee, in connection with any proposed assignment under
this Section 10.2 on not less than 10 days' written request, a certificate,
binding upon such Partner and its successors and assigns, stating (i) whether or
not, to its best knowledge, the assignor or pledgor is then in default under
this Agreement, and if in default, the nature of the same or whether an event
has occurred which, with the passage of time or giving of notice or both, would
constitute such a default, and (ii) that this Agreement is in full force and
effect and has not been amended, or if amended, the date of each amendment. Such
certificate may be relied upon, regardless of any independent inquiry, by the
assignor and pledgor and proposed assignee and pledgee and their respective
successors and assigns.

                    (b)  Such sale, Transfer or assignment must be for
consideration of all cash or cash plus a promissory note or notes.

                    (c)  The General Partner and each other Limited Partner
shall have Consented to the sale, assignment or Transfer which Consent any such
Partner may grant or withhold in its sole discretion.

                    (d)  Before selling, transferring or assigning its interest
in the Partnership in a transaction otherwise permitted under this Section 10.2,
the Limited Partner selling, transferring or assigning ("Assigning Limited
Partner") shall give written notice to the Non-Assigning Limited Partners of the
proposed transaction and shall deliver to the Non-Assigning Limited Partners
with such notice a copy of the bona fide written offer from a prospective
purchaser, assignee or Transferee (such notice from the Assigning Limited
Partner, together with such copy of the bona fide written offer, being
hereinafter collectively called "Partnership Offer Notice") setting forth the
name of the prospective purchaser, assignee or Transferee and all of the
material terms and conditions on which the Assigning Limited Partner intends to
sell, assign or Transfer such interest in the Partnership, and each of the
Non-Assigning Limited Partners shall then have 30 days after the giving of the
Partnership Offer Notice, together with the delivery of such offer, to elect (by
giving notice of the same to the Assigning Limited Partner) to purchase such
interest of

                                       37
<Page>

the Assigning Limited Partner for the purchase price and on the same terms and
conditions as set forth in such Partnership Offer Notice, and in the event any
of the Non-Assigning Limited Partners makes such election, the transaction shall
be closed within a period of 30 days after the making of such election, with the
time, place and date (within such period) as specified by the Non-Assigning
Limited Partner in the notice of its election. If any of the Non-Assigning
Limited Partners shall fail to give notice of this election, then the Assigning
Limited Partner may sell, Transfer or assign such Partnership interest (provided
such sale, transfer or assignment is otherwise permitted under this Section 10),
at any time or times within 180 days after the giving of such Partnership Offer
Notice, for a purchase price and on terms and conditions no more favorable to
the Transferee than those contained in the Partnership Offer Notice and only to
the person identified in the Partnership Offer Notice, and if such sale,
assignment or Transfer is not consummated within said 180-day period, then the
Non-Assigning Limited Partners' rights to notice and to purchase as aforesaid
shall reapply to any pending sale, assignment or Transfer, and continue with
respect to any other proposed sale, assignment or Transfer, of the Partnership
interest of the Assigning Limited Partner. The Non-Assigning Limited Partners
may in a written instrument waive any rights they may have pursuant to this
Section to purchase such interest of the Assigning Limited Partner for the
purchase price and on the same terms and conditions as set forth in the
Partnership Offer Notice.

          10.3      SUBSTITUTE LIMITED PARTNER. An assignee of the whole or any
part of a Limited Partnership interest shall have the right to become a
Substitute Limited Partner only if all of the following conditions are
satisfied:

of assignment which has been filed with the Partnership sets forth a statement
of the intention of the assignor that the assignee become a Substitute Limited
Partner;

Agreement and agrees to assume all or its pro rata share, as the case may be, of
the obligations

                                       38
<Page>

of its assignor, and a certificate evidencing the admission of such Person as a
Substitute Partner shall have been filed for recording;

                    (c)  any reasonable costs of the Transfer shall have been
paid to the Partnership; and

                    (d)  the General Partner shall have Consented to the
substitution, which Consent it may grant or withhold in its sole discretion.

          10.4      INVOLUNTARY WITHDRAWAL BY A LIMITED PARTNER.

                    (a)  If a Limited Partner who is a natural person does not,
by written instrument, designate a Person to become an assignee of his
Partnership interest upon his death, then his personal representative shall have
all the rights of such Partnership interest for the purpose of settling or
managing his estate, and such power as the descendent possessed to Transfer his
Partnership interest to an assignee and to join with such assignee in making
application to substitute such assignee as a Substitute Partner.

                    (b)  Upon the Bankruptcy, dissolution or other cessation of
existence of a Limited Partner which is not a natural person, the authorized
representative of such entity shall have all the rights of a Partner for the
purpose of effecting the orderly winding up and disposition of the business of
such entity and such power as such entity possessed to designate a successor as
an assignee of its Partnership interest and to join with such assignee in making
application to substitute such assignee as a Partner.

                    (c)  The death, Bankruptcy, dissolution, disability or legal
incapacity of a Limited Partner shall not dissolve or terminate the Partnership.

          10.5      TRANSFERS TO RELATED PARTIES. Notwithstanding anything in
this Section 10 to the contrary, any Limited Partner may sell, assign or
Transfer all or any part of its interest in the Partnership to any corporation
which is a Related Party with such Limited Partner without the Consent or
agreement of any other Partner,

                                       39
<Page>

and any such Related Party shall, upon such sale, assignment or Transfer become
a Substitute Limited Partner without the further Consent or agreement of any
other Partner; PROVIDED, HOWEVER, that such Related Party shall comply with the
requirements of Section 10.2(a) of this Agreement. Except as provided in this
Section 10.5, no such sale, assignment or Transfer shall require any prior
written notice to, or be subject to any election to purchase such interest in
favor of any other Partner as otherwise provided in Section 10.2 hereof. Prior
to or promptly following any such sale, assignment or Transfer by any Limited
Partner, such Limited Partner shall give written notice to all other Partners
advising of such sale, assignment or Transfer and identifying the Related Party
to which the same was made and identifying the interest owned or to be owned by
it.

          11.1      ASSIGNMENT OR WITHDRAWAL BY THE GENERAL PARTNER. The General

its Partnership interest shall be converted to that of a Limited Partner, and it
shall continue to have all the benefits of a Partner, except that it shall not
participate in the management of the Partnership or approve its successor

                    (e)  counsel for the Partnership shall have rendered an
opinion that none of the actions taken in connection with such transfer or
admission will have an adverse tax effect upon the Partnership, which opinion
can be waived by the Limited Partners; and

                    (f)  the remaining General Partner, if any, shall have
approved the admission of the successor Person.

          12.1      DISSOLUTION. No act, thing, occurrence, event or

Partnership for any reason, the Partner then having primary Partnership
management responsibility (unless such Partner is the Partner to whom the

have equal distribution percentages) shall commence to wind-up the affairs of
the Partnership and to liquidate its investments. The Partners shall continue to
share profits and losses, gain or loss on sale or disposition of Partnership
property, Net Cash Flow, and Net Sale or Refinancing Proceeds during the period

such audits (if any). The Partnership shall indemnify and reimburse the General
Partner for all expenses, including legal and accounting fees, claims,

proceeding, except to the extent required by law, is a matter in the sole
discretion of the General Partner; PROVIDED, HOWEVER, that the decision to take
any action or not to take any action shall be made in accordance with the
General Partner's fiduciary duty as set forth in Section 6.2 of this Agreement.

applicable to the General Partner in its capacity as Tax Matters Partner.

giving written notice of such change to the other Partners in the manner
provided in this Section 14.3.

          14.4      GOVERNING LAW. This Agreement shall be governed by the laws
of the State of Maine, without reference to conflicts of laws or the principles
thereof.

          14.5      HEADINGS. The headings of the articles and sections of this
Agreement are inserted for convenience only and are not to be deemed to
constitute a part of this Agreement.

          14.6      FURTHER AND ADDITIONAL DOCUMENTS AND REPORTS. Each of the
parties hereto agrees to execute, acknowledge and verify, if required to do so,
all further or additional documents as may be reasonably necessary to effectuate
fully the terms of this Agreement.

          14.7      COUNTERPARTS. This Agreement may be executed in
counterparts, each one of which shall be considered an original, and all of
which, when taken together, shall constitute one and the same instrument.

          14.8      BINDING ON SUCCESSORS AND ASSIGNS. Except as otherwise
specifically provided herein, this Agreement shall be binding upon and inure to
the benefit of the executors, administrators, successors, and assigns of the
respective Partners.

          14.9      WAIVER. The terms, conditions, covenants, representations,
and warranties hereof may be waived only by a written instrument executed by the
Partner waiving compliance. The failure of a Partner at any time or times to
require performance of any provision hereof shall in no manner affect its right
at a later time to enforce the same. The waiver of any breach of any term,
covenant, or condition of this Agreement by any of the parties hereto shall not
constitute a continuing waiver or waiver of any subsequent breach, either of the

                                       48
<Page>

same or of any other additional or different term, covenant, or condition of
this Agreement.

          14.10     SEVERABILITY. Whenever possible, each provision of this
Agreement and all related documents shall be interpreted in such a manner as to
be valid under applicable law, but if any such provision is invalid or
prohibited under said applicable law, such provision shall be ineffective to the
extent of such invalidity or prohibition without invalidating the remainder of
such provision or the remaining provisions of the affected documents.

          14.11     ATTORNEYS' FEES. The parties hereto agree that in the event
any party to this Agreement shall be required to initiate legal or arbitration
proceedings to enforce performance of any term or condition of this Agreement
including, but not limited to, the payment of monies or the enjoining of any
action prohibited hereunder, the prevailing party shall be entitled to recover
such sums, in addition to any other damages or compensation received, as will
reimburse such prevailing party for attorneys' fees and court and/or arbitration
costs incurred on account thereof, regardless of whether such action proceeds to
final judgment or determination.

          14.12     PROJECT INSPECTIONS. Each of the Partners and their duly
authorized representatives shall have the right to visit the Project and to make
inspections of the progress and quality of construction and management of the
Project and inquiries of the General Partner and its representatives as to the
foregoing.

          14.13     CREDITORS. None of the provisions of this Agreement shall be
for the benefit of or enforceable by a creditor of the Partnership or of a
Partner.

          14.14     REMEDIES. Except as may be provided explicitly in this
Agreement, the rights and remedies of any of the parties hereunder shall not be
mutually exclusive, and the exercise of one or more of the provisions hereof
shall not preclude the exercise of any other provision hereof. Each of the
Partners confirms that monetary

                                       49
<Page>

damages may be an inadequate remedy for breach or threat of breach of any
provision hereof. The respective rights and obligations hereunder shall be
enforceable by specific performance, injunction, or other equitable remedy, but
nothing herein contained is intended to limit or affect any rights at law or by
statute or otherwise of any party aggrieved as against the other for a breach or
threat of breach of any provision hereof, it being the intention by this Section
14.14 to make clear the agreement of the parties hereunder that this Agreement
shall be enforceable in equity as well as at law or otherwise.

          14.15     ARBITRATION. Any party hereto may require the arbitration of
any matter or matters arising under or in connection with this Agreement.
Arbitration is initiated and required by giving notice specifying the matter to
be arbitrated. If legal action is already pending on any matter concerning which
the notice is given, the notice is ineffective unless given before the
expiration of twenty (20) days after service of process on the person giving the
notice. Except as provided to the contrary in these provisions on arbitration,
the arbitration shall be held in Portland, Maine, and shall be in conformity
with and subject to the then applicable rules and procedures of the American
Arbitration Association (or any successor thereto). If the American Arbitration
Association is not then in existence and there is no successor, or if for any
reason the American Arbitration Association fails or refuses to act, the
arbitration shall be in conformity with and subject to the provisions of
applicable statutes (if any) relating to arbitration at the time of the notice.
The arbitrators shall be bound by this Agreement and all related agreements.
Pleadings in any action pending on the same matter shall, if arbitration is
required, be deemed amended to limit the issues to those contemplated by the
rules prescribed above. The costs of arbitration, including arbitrator's fees,
shall be paid by the nonprevailing party. The number and selection of
arbitrators shall be in accordance with the rules prescribed above, except that
each arbitrator selected shall be familiar with the subject matter of the issues
to be arbitrated, such as, by way of example, partnership accounting, or real
estate management, or such other subject matter as may be at issue.

          14.16     PAYMENTS ON NON-BUSINESS DAYS. Whenever any payment to be
made hereunder shall be stated to be due on a Saturday, Sunday or a public
holiday under the laws of the jurisdiction in which payment is to be made, such
payment may be made on the next succeeding business day.

          14.17     SCHEDULES AND EXHIBITS. Each of the Schedules and Exhibits
attached hereto is hereby incorporated herein and made a part hereof for all
purposes, and references thereto contained herein shall be deemed to include
this reference and incorporation.

          reduce the Operating Reserve Requirement, dollar for dollar, in an
          amount up to $10,000,000, provided that in no event shall such

           20.   Article 5 of the Limited Partnership Agreement is amended in
its entirety to read as follows:

          Article 5. APPLICATION OF NET CASH FLOW AND NET SALE OR REFINANCING
                     PROCEEDS.

           5.1   NET CASH FLOW. (a) Within 120 days after the end of each Fiscal
     Year of the Partnership, the Partnership shall make payments on the Limited
     Partner Loans and of the Management Fees of KTI, as General Partner,
     accrued as of February 28, 1990 and not previously paid from and to the
     extent of the Net Cash Flow for such Fiscal year as follows:

                  (i)  100% of such Net Cash Flow shall be applied to pay
          interest accrued on the Limited Partner Loans and the principal of the
          Limited Partner Loans up to the total amount attributable to accrued
          and unpaid interest theretofore capitalized and added to the principal
          balance due on such Limited Partner Loans through the date of payment;
          and

                 (ii)  After payment of the accrued interest on the Limited
          Partner Loans and any principal of the Limited Partner Loans then
          outstanding and attributable to accrued and unpaid interest
          capitalized and added to the principal balance due on such Limited
          Partner Loans through the date of payment, 100% of any remaining Net
          Cash Flow shall be applied to pay the balance of the principal on the
          Limited Partner Loans and the Management Fees of KTI accrued and
          unpaid as of February 28, 1990 (provided that until the management
          fees of KTI accrued and unpaid as of February 28, 1990 are fully paid,
          each $1 of Net Cash Flow available for application pursuant to this
          paragraph (b) shall be applied $.50 to the payment of such accrued
          Management Fees and $.50 to the payment of the principal of the
          Limited Partner Loans); and

           (b)   After payment in full of the Management Fees of KTI accrued and
     unpaid as of February 28, 1990, and all principal of and interest on the
     Limited Partner Loans, 100% of any remaining Net Cash Flow shall be applied
     to optionally redeem Bonds in inverse order of maturity.

           (c)   After payment in full of the Management Fees of KTI accrued and
     unpaid as of February 28, 1990 and all principal of and interest on the
     Limited Partner Loans and the Bonds, 100% of any remaining Net Cash Flow
     (and any reserves that are deemed available for distribution by the General
     Partner), subject to the provisions of the Waste Handling Agreements
     requiring Residual Cancellation Payments to be made to certain qualifying
     Charter Municipalities, shall be distributed as follows: 10% to the General
     Partner, 45% to Realty, 30% to ENI and 15% to Project Capital.

           5.2   NET SALE OR REFINANCING PROCEEDS. Net Sale or Refinancing
     proceeds shall be applied to pay the Limited Partner Loans, the accrued
     Management Fees due KTI as of February 28, 1990 and the Bonds when received
     in the same order of priority as provided in Section 5.1 for Net Cash

                                       -7-
<Page>

     Flow, and after payment in full of the Limited Partner Loans, the accrued
     Management Fees due KTI as of February 28, 1990 and the Bonds, any
     remaining Net Sale or Refinancing Proceeds, subject to the provisions of
     the Waste Handling Agreements requiring Residual Cancellation Payments to
     be made to certain qualifying Charter Municipalities, shall be distributed
     as follows: 10% to the General Partner, 45% to Realty, 30% to ENI and 15%
     to Project Capital.

           5.3   DISTRIBUTION IN KIND. During the existence of the Partnership,
     no Partner shall be entitled to receive as distributions from the
     Partnership of any Partnership asset other than money. If upon termination
     and liquidation of the Partnership and after the payment or provision for
     payment in full of the Limited Partner Loans, the Management Fees of KTI
     accrued as of February 28, 1990 and the Bonds, the General Partner
     determines that (a) an immediate sale of part or all of the assets of the
     Partnership would cause undue loss to the Partners, and (b) the assets of
     the Partnership would be readily susceptible to division for distribution
     in kind to the Partners, then to that extent the General Partner may
     distribute such assets to the Partners in kind, subject to the provisions
     of the Waste Handling Agreements requiring Residual Cancellation Payments
     to be made to certain qualifying Charter Municipalities.

           21.   The proviso in Section 6.1(c) is amended to require the consent
of ENI, Realty and Project Capital in place of ENI and Realty and the
parenthetical phrase in clause (i) is deleted.

           22.   Paragraph (c) of Section 6.1 is amended by deleting the proviso
at the end of such paragraph and replacing it with the following:

                 .... PROVIDED, HOWEVER, that, in addition to the limitations
     provided in Section 3.1(b)(ii), the General Partner shall not, without the
     prior consent of ENI, Realty and Project Capital (i) consent or agree to
     the substitution or replacement of the Credit Enhancer by any other Person,
     (ii) contract for or otherwise agree to the sale or mortgage of, or sell or
     grant a mortgage or security interest in, the Project, other than to secure
     the Bonds, (iii) permit the Partnership to issue any bonds, notes or other
     evidences of indebtedness in connection with any offer, issuance or sale
     thereof to the public, other than the Bonds, or (iv) create, incur, or
     assure any indebtedness for borrowed money except as permitted by the
     Reimbursement Agreement and borrowings from Partners pursuant to this
     Agreement. The General Partner shall serve as the Tax Matters Partner, as
     defined in the Code, and cause the preparation of all tax and information
     returns for the Partnership (including, but not limited to, Federal, state
     and local income tax and information returns).

           23.   Section 6.4 of the Limited Partnership Agreement is amended in
its entirety to read as follows:

           6.4   COMPENSATION. (a) In consideration of the services to be
     performed by the General Partner after the In-Service Date and through
     February 28, 1990 the General Partner shall be paid an annual Management
     Fee of $300,000 (of which amount it is acknowledged and agreed that
     $857,534

                                       -8-
<Page>

     was accrued and unpaid as of February 28, 1990), and from and after March
     1, 1990 the General Partner shall be paid a Management Fee in the amount of
     $16,667 per month in full payment of all of its profits and overhead costs
     for managing the Partnership; PROVIDED, HOWEVER, that the payment of such
     Management Fee shall at all times be subject to the terms and conditions of
     the Waste Handling Agreements, including the provisions in Subarticle C of
     Article XI of the Waste Handling Agreements requiring that KTI as General
     Partner shall forego the payment of a portion of such Management Fee to
     enable the Partnership to pay each Charter Municipality the Cancellation
     Adjustment (as defined in the Waste Handling Agreements).

           (b)   The General Partner will subordinate its Management Fees
     accrued through February 28, 1990, until the Partnership's Net Cash Flow
     and/or Net Sale or Refinancing Proceeds are sufficient to begin retiring
     the Limited Partner Loans in accordance with Section 5.1 and 5.2 of the
     Partnership Agreement; PROVIDED, HOWEVER, that a portion of such accrued
     and unpaid Management Fees may be paid out of Net Recoveries to the extent
     available as provided in Section 3.8 of the Partnership Agreement.

           24.   Section 6.6 of the Partnership Agreement is amended in its
entirety to read as follows:

           6.6   ESTABLISHMENT OF RESERVES. (a) The Partnership shall establish
     and maintain the Reserve Funds and such other funds as provided for by the
     Trust Indenture, the Reimbursement Agreement and the Waste Handling
     Agreements and shall cause to be deposited therein such amounts as are or
     may be required pursuant to the Loan Agreement, the Trust Indenture, the
     Reimbursement Agreement and the Waste Handling Agreements. At such time as
     the Partnership is no longer required to maintain such Reserve Funds or any
     such other funds, the amounts in such funds shall be applied in the same
     manner as Net Cash Flow.

           (b)   Pursuant to the terms of this Agreement, the General Partner
     may from time to time establish such reserves for the Partnership as it in
     good faith deems reasonable and necessary. At such time as the General
     Partner deems such reserves no longer necessary, they shall be applied in
     the same manner as Net Cash Flow. Without limiting the generality of the
     foregoing the General Partner shall establish and maintain reserves for the
     Cancellation Adjustments and Charter Adjustments (as defined in the Waste
     Handling Agreements) in a manner satisfactory to the Oversight Committee
     (as defined in the Operation and Maintenance Agreement).

           25.   Section 11.3 is amended to clarify that the reference therein
to Section 7.1 refers to Section 7.1 of the Reimbursement Agreement.

           26.   The following clause is hereby inserted at the beginning of the
second sentence of Section 12.3:

                 "Subject to the terms and conditions of the Waste Handling
     Agreements requiring Residual Cancellation Payments to be made to certain
     qualifying Charter Municipalities,...."
