Gentlemen:
In accordance with your request, we have performed the calculations
necessary to derive the cost depletion percentage for the 2007 calendar year.
The calculation of the cost depletion percentage required that we prepare a
report of the estimated remaining proved producing reserves attributable to
the overriding royalty interest of North European Oil Royalty Trust (the
"Trust") in the Northwest German Basin of the Federal Republic of Germany as
of October 1, 2007. The proved producing reserves are as of October 1, 2007
and the reported sales are for the twelve month period ending September 30,
2007. The use of the period ending September 30, 2007 is consistent with
prior years and allows the timely calculation of the royalty reserves and the
cost depletion percentage for the calendar year.
Based on the results of our calculation of the estimated remaining
proved producing reserves contained in the first part of this report, we have
performed the calculations necessary to derive the cost depletion percentage
for the 2007 calendar year. As detailed in Attachment B, the cost depletion
percentage for the 2007 calendar year for Trust unit owners is equal to
8.5046% of their cost basis as of January 1, 2007.
DESCRIPTION OF HOLDINGS
-----------------------
The Trust holds various overriding royalty rights on sales of gas,
sulfur and oil from certain concessions and leases in the Federal Republic
of Germany. The Oldenburg concession (1,398,000 acres), covering virtually
the entire former State of Oldenburg and located in the State of Lower
Saxony, is held by Oldenburgische Erdolgesellschaft ("OEG"). OEG in turn
is owned by Mobil Erdgas-Erdol GmbH ("Mobil Erdgas"), the German subsidiary
of ExxonMobil Corp. and by BEB Erdgas und Erdol GmbH ("BEB"), a joint
venture of ExxonMobil Corp. and the Royal Dutch/Shell Group. As a result by
direct and indirect ownership, ExxonMobil Corp. owns two-thirds of OEG and the
Royal Dutch/Shell Group owns one-third of OEG.

The Oldenburg concession is the major source of royalty income for
the Trust. Although the Trust has interests in other producing areas,
reserves and net sales for these areas are no longer used in the calculation
of the annual cost depletion percentage. While the Trust continues to
receive royalty payments from one of these interests, these royalties
represent less than one (1) percent of the Trust's total royalties and the
expenses involved in the determination of reserve estimates for this
interest is not warranted by the royalties received. The exclusion of
these reserves does not have a material effect on the calculation of the
cost depletion percentage. We will continue to monitor the quarterly
statements and if increases are noted that could materially add reserves
to the Trust, we will resume estimating future reserves.
1. In 2002 Mobil Erdgas and BEB formed a new company ExxonMobil
Production Deutschland GmbH to carry out all exploration,
drilling and production within the Oldenburg concession.
All sales activities are still handled by either Mobil
Erdgas or BEB.
(a) Under one series of rights covering the western part of
the Oldenburg concession (approximately 662,000 acres),
the Trust receives a royalty payment of 4% on gross
receipts from sales by Mobil Erdgas of gas well gas,
oil well gas, crude oil and condensate (the "Mobil
Agreement"). Under the Mobil Agreement there is no
deduction of costs prior to the calculation of royalties
from gas well gas or oil well gas, which together
account for approximately 99% of all the royalties
under said agreement.
(b) Under another series of rights covering the entire
Oldenburg concession and pursuant to an agreement with
OEG, the Trust receives royalties at the rate of 0.6667%
on gross receipts from sales of gas well gas, oil well
gas, crude oil, condensate and sulfur (removed during the
processing of sour gas) less a certain allowed deduction
of costs (the "OEG Agreement"). Under the OEG Agreement,
50% of the field handling, treatment and transportation
costs as reported for state royalty purposes are deducted
from gross sales receipts prior to the calculation of the
royalty to be paid to the Trust.
(c) The Trust is also entitled to receive from Mobil Erdgas a
2% royalty payment on gross receipts of sales of sulfur
obtained as a by-product of sour gas produced from the
western part of Oldenburg. However, the payment of the
sulfur royalty is provisional on whether Mobil Erdgas'
selling price meets or exceeds the escalated base price.
Throughout fiscal 2006, Mobil Erdgas' selling price was
below the escalated base price. We will continue to
monitor this situation, but until the point that Mobil
Erdgas' selling price again meets or exceeds the escalated
base price, reserves subject to this royalty will not be
included in overall reserve calculations.

OLDENBURG AREA - SALES AND RESERVES
------------------------------------
The Trust's royalty income comes primarily from the Oldenburg area.
Gas production accounts for the majority of the income; however, the
hydrogen sulfide in much of the gas produced necessitates its removal
before the gas can be sold. At the Grossenkneten desulfurization plant, the
hydrogen sulfide in sour gas is removed. Following earlier renovations and
improvements to the plant, the plant's present input capacity stands at
679.4 million cubic feet per day ("MMcf per day"). A second desulfurization
plant NEAG remains connected by pipeline with the transportation system of
the Oldenburg concession but is currently being utilized only to a limited
degree for the processing of gas from Oldenburg.
TOTAL SALES
-----------
During the twelve months ending September 30, 2007 total sales for
the Oldenburg area were as follows:
WEST EAST TOTAL
---- ---- -----
Gas Well Gas-MMcf 65,859 90,522 156,381
Oil Well Gas-MMcf 51 17 68
Oil & Condensate-Barrels 121,716 66,655 188,371
Sulfur-Short Tons 262,984 638,420 901,404
GROSS RESERVES
--------------
Estimated gross remaining proved producing reserves attributable
to the total Oldenburg area are as follows:
WEST EAST TOTAL
---- ---- -----
Gas Well Gas-MMcf 622,924 1,569,246 2,192,170
Oil Well Gas-MMcf 332 120 452

NET RESERVES
------------
To present an accurate picture of estimated proved producing
reserves net to the Trust, the gross reserve figures outlined above must be
modified by the impact of the different royalty rates in effect in the
Oldenburg concession. A comparison of the Trust's overriding royalty rates
in both the western and eastern areas of Oldenburg is as follows:
Mobil Erdgas West East
--------------- ---------- ----------
Gas & Oil 4% 0%
Sulfur 2%* 0%
BEB
---------------
Gas & Oil 0.6667%** 0.6667%**
Sulfur 0.6667%** 0.6667%**
*Temporarily suspended. (See prior explanation.)
**Prior to the calculation of royalties, 50% of costs as reported for
state royalty purposes are deducted.
The application of these royalty rates to the estimated gross
remaining proved producing reserves attributable to the western and eastern
Oldenburg areas yields the combined estimated proved producing reserves net
to the Trust. The Trust's estimated remaining net proved producing reserves
as of October 1, 2007 and net sales for the twelve month period ending
September 30, 2007 are as follows:
Reserves Sales
-------- -----
Gas Well Gas-MMcf 38,240 3,586
Oil Well Gas-MMcf 14 2
Oil & Condensate-Barrels 83,556 5,934
Sulfur-Short Tons 53,269*** 3,822***
*** Note: At current price levels no royalties are being paid
under the Mobil Erdgas sulfur royalty.
A summary of net proved producing reserves by product and a five
year history of net sales attributable to the royalty interests of the Trust
are presented in Attachment A.

LIMITATIONS OF AVAILABLE DATA
-----------------------------
The reserves considered in this report are defined as proved
producing reserves. Proved producing reserves are limited to those
quantities which can be expected to be recoverable commercially from known
reservoirs at current prices and costs, under existing regulatory practices
and with existing conventional equipment and operating methods. Proved
producing reserves do not include either proved developed non-producing
reserves or any class of probable reserves.
The reserve estimates were prepared using engineering methods
generally accepted by the petroleum industry. The reliability of any
reserve estimate is a function of the quality of available information and
of engineering interpretation and judgment.
The Trust, as an overriding royalty interest owner, does not
receive proprietary data from the various operators on producing wells.
Data, such as logs, core analysis, reservoir tests, pressure tests, gas
analyses, geologic maps, and individual well production histories on all of
the wells, which are used in volumetric and material balance type reserve
estimates, are not available to the Trust.
The Trust receives various monthly and quarterly statements from
the operators that report production, sales and revenue data. Utilizing the
same procedures as in prior years, this information plus published
information received from W.E.G. (a German organization comparable to the
American Petroleum Institute or the American Gas Association) has been used
to prepare this annual report. In addition, the Trust retains a part-time
consultant in Germany who is familiar with the German petroleum industry in
general and the operating companies in particular. His periodic reports
and communications are considered in the preparation of this report. We
believe that reserve estimates prepared using all the available data are
appropriate for use in the calculation of the cost depletion percentage.
However, due to the limitations of available data, this estimate of reserves
cannot have the same degree of accuracy that an estimate of reserves prepared
using all pertinent data would have. Our experience in the evaluation of
reserves using such limited data, including sixteen (16) years of experience
working for the Trust, compensates somewhat for the limitations of available
data.
The data in the reports received by the Trust is in metric tons and
cubic meters. The following Metric to English Unit conversion factors were
used:
Gas: 37.25 cubic feet per cubic meter at 14.7 psia
and 60 degrees Fahrenheit
Oil: 7.23 barrels per metric ton
Sulfur: 1.1 short tons per metric ton

CALCULATION OF COST DEPLETION PERCENTAGE
----------------------------------------
The categories of proved producing reserves considered in the
calculation of the cost depletion percentage are oil, oil well gas, and
gas well gas. Sulphur is a by-product of gas production and is not
considered in the computation of total cost depletion percentage.
For each category of reserves, a product base was established for
the Trust as of January 1, 1976. Through the use of these product bases, we
can account for the relative size of each of these categories of reserves and
the corresponding impact on the calculation of the cost depletion percentage.
The product base for each category of proved producing reserves is reduced
annually by an adjustment that is calculated by multiplying the product base
at the beginning of the current year by the depletion factor for that
category of reserves. The depletion factor for each category of reserves is
the ratio of the relevant net sales during the current year to the
corresponding adjusted net proved producing reserves at the beginning of the
current year.
Significant items in the cost depletion percentage calculation that
appear on Attachment B as specific item numbers, shown in parentheses, and
their sources are as follows:
The adjusted estimated net proved producing reserves as of
10/1/06 Line (3) is obtained by adding the estimated remaining
net proved producing reserves as of 10/1/06 Line (1) and the
adjustments to reserves during the period Line (2). Therefore
Line (3) = Line (1) + Line (2).
The depletion factor Line (6) for each category of proved
producing reserves is obtained by dividing the relevant net
sales Line (4) by the corresponding adjusted estimated net
proved producing reserves as of 10/1/06 Line (3). Therefore
Line (6) = Line (4) / Line (3).
The product base for each category of proved producing
reserves as of 1/1/06 Line (7) and the adjustment taken during
2006 Line (8) were obtained from the previous year's report.
The product base as of 1/1/07 Line (9) forms the initial
starting point for the calculation of the cost depletion
percentage for the 2007 tax year. The product base for
1/1/07 Line (9) then is Line (7) - Line (8).
The adjustment to the product base for each category of proved
producing reserves Line (10) is used to reduce the product
base as of the beginning of each year. This adjustment is the
product of the depletion factor for each category of proved
producing reserves Line (6) multiplied by the corresponding
product base as of 1/1/07 Line (9). Therefore Line (10) =
Line (6) x Line (9).
- 55 -
North European Oil Royalty Trust December 14, 2007
Page 7
The cost depletion percentage Line (11) then is the sum of the
adjustment to the product base of each category of proved
producing reserves [Sum Line (10)] divided by the sum of the
product base for each category as of 1/1/07 [Sum Line (9)].
Therefore Line (11) = [Sum Line (10)] / [Sum Line (9)].
The cost depletion percentage represents the total allowable cost
depletion for the 2007 calendar year for the Trust's unit owners, expressed
as a percentage of their cost base as of January 1, 2007.
