3. Legal Matters

As reported by the Trust in it's Form 10K for the year ended December 31, 2000,
on June 2, 2000, Indeck Maine filed a "Complaint Requesting Fast Track
Processing And Request For Immediate Action" with the Federal Energy Regulatory
Commission ("FERC") seeking FERC's removal of bid restrictions placed on Indeck
Maine's Projects. The Complaint asserted that the actions of the ISO in setting
bid caps and unilaterally mitigating Indeck Maine's bids far exceeded its
authority under the ISO's market rules. On July 26, 2000, FERC agreed with
Indeck Maine and ruled that the ISO had no basis to impose bid restrictions upon
Indeck Maine but, concluded, that "[we] will grant Indeck's request to order
ISO-NE to remove the bid caps on Indeck's units as of the date of this order."
Unfortunately, FERC failed to rule that the ISO bid caps and other restrictions
were improper from their inception. On August 25, 2000, Indeck Maine filed a
motion with FERC seeking a clarification that the bid restrictions were improper
from inception or, in the alternative, a rehearing on that issue. FERC has yet
to rule on the matter.

In addition, as stated above, in early October 1999, the ISO informed the Trust
that a scheduled transmission outage for October 16 and 17 required the ISO to
activate all possible generation in Maine. The Maine Biomass Projects, which had
been shut down and which did not have full crews available, had a pre-existing
offer to supply electric energy at a high price, reflecting the costs of
restarting the plants, obtaining a crew on short notice and covering fixed
costs. The ISO accepted the offer subject to its market rules and conditions.
The Maine Biomass Plants operated as dispatched by the ISO on October 16 and, if
they were paid in accordance with their offer terms, would have received in
excess of $2.2 million. In November 1999, the ISO advised RPM that it would pay
a total of $5,000 for the energy the Projects produced on October 16. The ISO
has stated that, in its opinion, the Projects had monopoly-like market power on
October 16 and that under the existing market rules it was only obligated to pay
a rate based on variable costs unless the Projects could cost-justify a higher
rate.

As a result, on October 24, 2000, Indeck Maine filed a complaint against the ISO
in the Superior Court of Delaware alleging, among other things, that the ISO's
action in October 1999 resulted in a breach of an express or implied contract,
violated certain consumer protection laws and amounted to fraud. The ISO removed
the litigation to Federal District Court in Delaware and filed a motion to
dismiss Indeck's claims as improperly brought before the Court. ISO claims such
matters belong before FERC. Indeck Maine opposed the ISO motions and filed a
motion to remand the matter back to the Delaware courts. On October 9, 2001, the
Federal District Court in Delaware decided the various motions before it and
held that Indeck Maine's complaint be dismissed. Essentially, the Federal
District Court agreed with the ISO and decided that the claims of Indeck Maine
should be brought before FERC, rather than a court of law. Indeck Maine has
filed an appeal of the District Court's decision to the Federal Court of Appeals
for the Third Circuit and is determining whether to bring a complaint against
the ISO before FERC.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations Dollar amounts in this discussion are rounded to the nearest
$1,000.IntroductionThe consolidated financial statements include the accounts of
the Trust and the limited partnerships owning the Providence Project and the
California Pumping Project. The Trust uses the equity method of accounting for
its investments in the Maine Hydro Projects, the Maine Biomass Projects and the
Santee River Rubber Project, which are owned 50% or less by the Trust. Results
of Operations In the third quarter of 2001, the Trust had total revenue of
$1,930,000, which is comparable with total revenue of $1,936,000 in the same
period in 2000. Total revenues for the first nine months of 2001 of $5,727,000
were also comparable with total revenue of $5,580,000 in the same period in
2000. Cost of sales of $1,770,000 in the third quarter of 2001 ($4,761,000 in
the first nine months of 2001) increased by $417,000 from cost of sales of
$1,353,000 for the same period in 2000 ($4,455,000 in the first nine months of
2000). The increase is primarily due to the higher maintenance costs incurred at
the Providence Project.

General and administrative expenses in the third quarter of 2001 of $408,000
were higher than the $165,000 recorded in the same period for 2000, primarily
due to the higher administrative expenses incurred at the Providence Project and
higher professional fees at the Trust level. General and administrative expenses
for the first nine months of 2001 of $856,000 were also higher than the $656,000
recorded in the same period in 2000 for the same reason. Management fees
increased to $171,000 in the third quarter of 2001 ($590,000 in the first nine
months of 2001) as compared to the zero for the same period in 2000 ($213,000 in
the first nine months of 2000), as a result of the Managing Shareholder's
decision to resume taking 100% of the management fee effective January 1, 2001.
In 2000, the Managing Shareholder had waived 50% of the management fee.

Interest expense was reduced from $91,000 in the third quarter of 2000 ($285,000
for the first nine months of 2000) to $73,000 in the third quarter of 2001
($232,000 for the first nine months of 2001) due to lower borrowings outstanding
at the Providence Project.

The equity loss from the Maine Hydro Projects for the first nine months of 2001
was $50,000, a decrease of $329,000 as compared to $279,000 of equity income for
the same period of 2000. The loss for the third quarter of 2001 was $322,000, a
decrease of $60,000 as compared to the third quarter of 2000 loss of $382,000.
The decrease in income is due to the below average river flows for 2001.

The equity loss from the Maine Biomass Projects for the first nine months of
2001 was comparable to that of the first nine months of 2000. The Maine Biomass
Projects provided $144,000 of equity income for the third quarter of 2001
compared to an equity loss of $125,000 for the third quarter of 2000. The
increase in third quarter income is due to the West Enfield plant returning to
full time operation during the second quarter of 2001.

The equity loss in the Santee River Rubber project of $181,000 for the first
nine months of 2000 did not recur due to the writedown of the project in the
third quarter of 2000.

Liquidity and Capital Resources

In 1997, the Trust and Fleet Bank, N.A. (the "Bank") entered into a revolving
line of credit agreement, whereby the Bank provides a committed line of credit
facility of $1,150,000. The line of credit facility expires in July 2002.
Outstanding borrowings bear interest at the Bank's prime rate or, at the Trust's
choice, at LIBOR plus 2.5%. The credit agreement requires the Trust to maintain
a ratio of total debt to tangible net worth of no more than 1 to 1 and a minimum
debt service coverage ratio of 2 to 1. The credit facility was obtained in order
to allow the Trust to operate using a minimum amount of cash, maximize the
amount invested in Projects and maximize cash distributions to shareholders. In
the first quarter of 2000, the Trust borrowed $500,000 under the credit
facility, which was later repaid during the third quarter of 2000.

Obligations of the Trust are generally limited to payment of the management fee
to the Managing Shareholder, scheduled long-term debt payments related to the
Providence Project and payment of certain accounting and legal services to third
parties. The Trust ceased making distributions to shareholders in the first
quarter of 2000.

The Trust anticipates that its cash flow during 2001 will be adequate to fund
its obligations.

Forward-looking statement advisory

This Quarterly Report on Form 10-Q, as with some other statements made by the
Trust from time to time, contains forward-looking statements. These statements
discuss business trends and other matters relating to the Trust's future results
and the business climate and are found, among other places, in the notes to
financial statements and at Part I, Item 2, Management's Discussion and
Analysis. In order to make these statements, the Trust has had to make
assumptions as to the future. It has also had to make estimates in some cases
about events that have already happened, and to rely on data that may be found
to be inaccurate at a later time. Because these forward-looking statements are
based on assumptions, estimates and changeable data, and because any attempt to
predict the future is subject to other errors, what happens to the Trust in the
future may be materially different from the Trust's statements here.

The Trust therefore warns readers of this document that they should not rely on
these forward-looking statements without considering all of the things that
could make them inaccurate. The Trust's other filings with the Securities and
Exchange Commission and its Confidential Memorandum discuss many (but not all)
of the risks and uncertainties that might affect these forward-looking
statements.

Some of these are changes in political and economic conditions, federal or state
regulatory structures, government taxation, spending and budgetary policies,
government mandates, demand for electricity and thermal energy, the ability of
customers to pay for energy received, supplies of fuel and prices of fuels,
operational status of plant, mechanical breakdowns, availability of labor and
the willingness of electric utilities to perform existing power purchase
agreements in good faith. Some of the cautionary factors that readers should
consider are described in the Trust's most recent Annual Report on Form 10-K.

By making these statements now, the Trust is not making any commitment to revise
these forward-looking statements to reflect events that happen after the date of
this document or to reflect unanticipated future events.
