Ms. Connie Kelly
Chief Financial Officer
South Dakota Soybean Processors
PO Box 500
Volga, South Dakota 57071

RE:   A Complete Appraisal of the Processing Plant and Related Assets
      Located at Volga, South Dakota, owned by South Dakota Soybean
      Processors

Ms. Kelly:

I have inspected the above subject property and related assets as outlined in
the enclosed complete appraisal report in a summary report format dated June 30,
2001. The purpose of this report is to estimate the Market Value for an internal
company purpose. For special purpose properties of this type, it is my opinion a
market value sale could include a time period up to one year.

The value conclusion reached is subject to the assumptions and limiting
conditions as set forth in the accompanying report. Only the assets outlined
herein are appraised. The property rights appraised are the Business Enterprise
which includes the going concern and the underlying property rights of Fee
Simple Estate on the owned land, Leasehold Estate on leased land (if any) with
Merchantable Title to all fixed assets, rolling and portable equipment appraised
herein, free and clear of any liens. This appraiser has not considered any
possible noncompliance (if any) with the requirements of the Americans with
Disabilities Act (ADA). The appraisal is based on the assumption that there is
no environmental contamination above any threshold that would require any
remediation. An independent audit of any environmental concerns should be
conducted by an appropriately qualified inspection company. This appraisal
report has been prepared in compliance with the Uniform Standard of Professional
Appraisal.

Based on my investigation and analysis of the data gathered, I have formed the
opinion that the Market Value of the subject property which includes the
business enterprise, fee simple estate, leasehold estate (if any), buildings,
improvements, rolling and portable equipment "as is" free and clear of any liens
as outlined in the enclosed report as of June 30, 2001, was a total of
Thirty-Three Million Nine Hundred Thousand Dollars ($33,900,000). The
contribution of personal property (rolling and portable equipment) was estimated
at Four Hundred Ten Thousand Dollars ($410,000). The contribution of the fee
simple estate and leasehold estate (if any) which includes the going concern
(business enterprise) was estimated at Thirty-Three Million Four Hundred Ninety
Thousand Dollars ($33,490,000). See page 99 for discussion on other asset
values.

                                       AND
                               LIMITING CONDITIONS

                                                            Date: July 26, 2001

I certify that to the best of my knowledge and belief, the statements of facts
contained in this appraisal report are true and correct.

The reported analyses, opinions, and conclusions are limited only by the
reported assumptions and limiting conditions, and are my personal, unbiased
professional analyses, opinions and conclusions.

I have no present or prospective interest in the property that is the subject of
this report, and I have no personal interest or bias with respect to the parties
involved.

The compensation payable to Dennis E. Vogan of Mid-States Appraisal Services,
Inc. is not contingent upon the reporting of a predetermined value or direction
in value that favors the cause of the client, the amount of the value estimate,
the attainment of a stipulated result, or the occurrence of a subsequent event.

The analyses, opinions, and conclusions were developed and this appraisal report
has been prepared in conformity with the Uniform Standards of Professional
Appraisal Practice. It is also subject to the requirements of the Code of
Professional Ethics and Standards of Professional Practice of the appraisal
organizations with which the Appraiser is affiliated.

I have made a personal inspection of the subject property covered within this
report on May 18, 2001.

No one has provided significant professional assistance to the person signing
this report. Also, this appraisal assignment was not based on a requested
minimum valuation, a specific valuation or the approval of a loan.

The use of this report is subject to the requirements of the Appraisal Institute
and other professional organizations relating to review by its duly authorized
representatives.

It is assumed that all parcels of land associated with this appraisal are owned
or leased as outlined in the enclosed report, and that all structures are
properly located on said lots. Also, it is assumed that all applicable zoning
and use regulations and restrictions have been complied with, unless a
nonconformity has been stated, defined, and considered in the appraisal report.

consultation, testimony or be in attendance in court or any governmental
hearing, with reference to the subject property, unless arrangements have been
previously made. No responsibility is assumed for the legal description, or for
matters including legal or title considerations. Title to the property is
assumed to be good and marketable unless otherwise stated. The property is
appraised free and clear of any or all liens or encumbrances unless otherwise

                         CERTIFICATION OF THE APPRAISER
                                       AND
                               LIMITING CONDITIONS

                                                          Date:  July 26, 2001
(continued)

The owner of the property has not advised this appraiser of any significant
environmental concerns. This appraisal is based on the assumption that there are
no hidden or unapparent conditions including any environmental contamination of
the property, subsoil, structures, or production equipment and machinery that
would render it more or less valuable. The Appraiser is not trained as an
environmental inspector and assumes no responsibility for such conditions, or
for engineering which might be required to discover such factors. If the
property were contaminated, the reported conclusion would require an adjustment
to consider the effects of the change. An independent audit of any environmental
concerns should be conducted by an appropriately qualified inspection company.

It is assumed that there is full compliance with all applicable federal, state
and local environmental regulations and laws unless noncompliance is stated,
defined, and considered in the appraisal report.

Possession of this report, or a copy thereof, does not carry with it the right
of publication. It may not be used for any purpose by any person other than the
party to whom it is addressed without the written consent of the appraiser, and
in any event only in its entirety.

No analysis regarding any possible noncompliance with the Americans With
Disabilities Act (ADA) has been considered by this appraiser.

It is assumed that all required licenses, certificates of occupancy, consents,
or other legislative or administrative authority from any local, state, or
national government or private entity or organization have been or can be
obtained or renewed for any use on which the value estimate contained in this
report is based.

The subject property in whole has not sold within the last three years. There
have been additions and deletions in the normal course of business.

                           DEFINITION OF MARKET VALUE(2)

Market value is the most probable price that a property should bring in a
competitive and open market under all conditions requisite to a fair sale, with
the buyer and seller each acting prudently and knowledgeably, and assuming the
price is not affected by undue stimulus. Implicit in this definition is the
consummation of a sale as of a specified date and the passing of good title from
seller to buyer under conditions whereby:

1.   buyer and seller are typically motivated;

2.   both parties are well informed or well advised, and acting in what they
     consider their own best interests;

3.   a reasonable period of time is allowed for exposure in the open
     market;

4.   payment is made in terms of cash in United States dollars or in
     terms of financial arrangements comparable thereto; and

5.   the price represents the normal consideration for the property sold
     unaffected by special or creative financing or sales concessions
     granted to anyone associated with the sale.


                     DEFINITION OF BUSINESS ENTERPRISE2

A commercial, industrial or service organization pursuing an economic activity.
This also includes the "Going Concern Value", which is the value of an
enterprise, or an interest therein as a going concern.


                         FEDERALLY RELATED TRANSACTIONS

A federally related transaction is any real estate related financial transaction
which a federal financial institution's regulatory agency engages in, contracts
for, or regulates and which requires the services of a real estate appraiser or
state certified real estate appraiser. "Federal financial institution's
regulatory agency" includes the Federal Reserve Board; Federal Deposit Insurance
Corporation; Office of the Comptroller of the Currency; Office of Thrift
Supervision; Federal Home Loan Bank System; National Credit Union Administration
and the Resolution Trust Corporation.

Typical reasons for appraisals that are NOT federally related transactions
include: estate, divorce, insurance, condemnation proceedings and market value
estimates for internal company or marketing purposes.

SOUTH DAKOTA SOYBEAN PROCESSORS                             VOLGA, SOUTH DAKOTA


                                AREA DESCRIPTION

The state of South Dakota is located in north central United States. Corn was
the leading valued crop of 2000 at $689.9 million. Soybeans ranked as the second
highest valued crop in the state at $680.6 million. Net farm income in South
Dakota was estimated by the South Dakota Agricultural Statistics Service at
$1.19 billion in 1999. This is down 3% from 1998, according to the Agricultural
Statistics Service. Because of depressed crop prices, value of crops produced in
1999 was $429 million dollars below 1998. This was offset by an increased value
in livestock production and an increase in direct government payments over 1998.
Cash receipts for producers in the state for all commodities marketed in 1999
totaled $3.5 billion dollars, which is 4 percent above 1998. Lower crop prices
were offset by more crop sales and higher livestock prices. Crops accounted for
48% of all receipts.

Soybeans had the largest acreage of all crops in South Dakota for 2000. Soybean
production in 2000 was 152.95 million bushels, up 4% from the record production
of 1999. This was a result of increased acres and overall good yields.

While the end of 2000 is the third year in a row of low commodity prices, the
latest information released that for the year ending 2000 shows that net farm
income will be similar to the averages of 1998 and 1999. The primary reasons
behind this have been good production, loan deficiency payments, and other
government payments are keeping net farm income at current levels.

While United States agricultural exports are expected to remain flat, the year
2001 is projected to be a continuation of a period higher world economic growth.
According to information released in the latest ECONOMIC OUTLOOK FOR US
AGRICULTURAL TRADE published by the Economic Research Service of the US
Department of Agricultural, the global financial crisis has ended. Recoveries
are underway in most all of the crises-affected countries. A tremendous amount
of uncertainty has been taken out of the international economy. Japan has
returned to growth after a long period of stagnation. The United State continues
to grow with gross domestic product growing at approximately 2% for the year.
The United States may avoid a recession; however, the Federal Reserve is moving
very cautiously on interest rate reduction. While overall US agricultural
exports are expected to remain flat in fiscal 2001, Canada and Mexico are
expected to continue to be bright spots for US agricultural exports as they have
been for the last several years.

For the planting season of 2001, it is estimated that U.S. farmers have planted
75.4 million acres of soybeans. This estimated is 0.9 million acres more than
last years record, but 1.2 million acres less than farmers intentions in March
of 2001. Farmers in Arkansas, Mississippi, and Louisiana elected to plant more
cotton instead of soybeans. Conversely, soybean plantings were down nearly 1.0
million acres because of wet weather conditions in the states of Minnesota,
South Dakota, North Dakota, and Wisconsin. There is the anticipation of
continuing strength in domestic crushing and exports for 2001. Domestic soybean
crushing will be supported this season and next season by firming prospective
export demand for soybean products, particularly soybean oil. The U.S. crush is
expected to rise to 1,660 million bushels from a revised 2000/2001 forecast of
1,625 million bushels. The very large U.S. stocks of soybean oil have weighed on
current oil prices. However, they represent a good opportunity to take advantage
of the outlook for much large foreign exports in 2001/2002. Declines in other
vegetable oil supplies throughout the world are expected to swell the U.S.
soybean oil exports from 1,500 million pounds in 2000/2001 to 2,250 million
pounds. Domestic disappearance of soybean oil should also rise in this time
period. The stronger world market for soybean oil would begin to favor crushing
more beans for the oil value than for meal. Favorable hog prices should promote
a steady expansion of domestic soybean meal consumption over the next 12 months.
In general, profit margins in the crushing industry are in acceptable ranges
providing profitable opportunities.

SOUTH DAKOTA SOYBEAN PROCESSORS                             VOLGA, SOUTH DAKOTA


                            NEIGHBORHOOD DESCRIPTION

The rural community of Volga, South Dakota, is located approximately 66 miles
northwest of Sioux Falls, South Dakota, on Highway 14, or approximately 7 miles
west of Brookings, South Dakota. The population for Brookings County in 1999 was
25,931. The estimated population for Volga in 1999 was 1,350.

The subject property is a soybean crushing plant which produces meal and oil.
Its primary production area is eastern South Dakota. South Dakota is divided
into nine agricultural statistics districts. The subject property at Volga,
South Dakota, is located in the East Central district.

For the year ending August 31, 2000, South Dakota Soybean Processors crushed
26.25 million bushels of soybeans. This is 17.16% of the total soybeans grown in
the state of South Dakota in the year 2000; or 38.6% of the total beans grown in
the Northeast and East Central Districts which produced 68 million bushels in
the year 2000.

The agricultural production for the state of South Dakota is significant. The
state is ranked 8th in the United States in soybean production for beans.
Soybean production has ranged from a low of 75 million bushels in 1995 to a high
of 152.950 million bushels in 2000. These agricultural statistics for the last
five years of soybean production are summarized in table form on page 14.

In the last year there has been soybean crushing plants and refineries in the
United States that have been closed. This industry experiences cycles. The
subject property has continued to grow in volume in a well established bean
production area.

In summary, the subject's production area is stable with a wide diversification
in grain crops.

SOUTH DAKOTA SOYBEAN PROCESSORS                             VOLGA, SOUTH DAKOTA


                              HIGHEST AND BEST USE

The highest and best use is defined in THE APPRAISAL OF REAL ESTATE, eleventh
edition, published by the Appraisal Institute as follows:

      The reasonably probable and legal use of vacant land or an improved
      property, which is physically possible, appropriately supported,
      financially feasible, and that results in the highest value. The four
      criteria that highest and best use must meet are legal permissibility,
      physical possibility, financial feasibility and maximum profitability.

LEGAL PERMISSIBILITY

The subject property's site is located adjacent to DM&E railroad right-of-way
and Highway 14 in the western portion of Brookings County near Volga, South
Dakota. Electricity, telephone, natural gas, water and on-site septic sewer
services are available. The site is reportedly not located in a designated flood
plain area. The site is zoned Commercial/Industrial. This appraisal assumes that
all applicable zoning and use regulations and restrictions have been complied
with unless a nonconformity has been stated, defined and considered in this
report.

PHYSICAL POSSIBILITY

The site contains a total of 46.84 acres, more or less, and is adequate for
development. It is predominantly level with access to a railroad and paved
highway.

FINANCIAL FEASIBILITY

Based on the physical possibility and legal permissibility, the creation of a
net return to land higher than a vacant alternative indicates that development
could be feasible. There is limited demand for new agribusiness properties of
the scope and size that currently exists. Without specific needs, the site would
most likely be developed for alternative uses if it were vacant.

MAXIMUM PROFITABILITY

If the site was vacant today, its highest and best use would be for an
industrial usage such as the subject.

The highest and best use of the site as improved is to continue its specialized
use in the grain services area, specifically soybean crushing. There are few
alternative uses for highly specialized properties such as the subject.

                             SCOPE OF THE APPRAISAL

Connie Kelly, the Chief Financial Officer of South Dakota Soybean Processors,
requested this appraisal firm to provide a complete appraisal in a summary
report format on the soybean crushing operations and related assets located at
Volga, South Dakota. The purpose of this appraisal report is to provide an
opinion of market value for an internal company purpose. The appraisal report
includes the going concern (business enterprise) and the underlying ownership
rights of fee simple estate on owned land, leasehold estate on leased land (if
any), with merchantable title to all rolling and portable equipment included
herein.

This appraiser interviewed Connie Kelly, CEO, Rodney Christiansen, President,
and other line operating personnel of this operation. Historical income and
expense information in the form of financial reports for the years ending August
31, 2000 through August 31, 1996 have been reviewed by this appraiser, along
with the current year-to-date information ending June 30, 2001.

The scope of this appraisal includes the collecting, confirming and reporting of
data. This appraiser collected and verified data for this appraisal from
reliable local and state governmental offices, buyers/sellers, brokers and
financial institutions.

                              ENVIRONMENTAL HAZARDS

The appraiser is not qualified to detect environmental hazards. The presence of
substances such as underground petro-chemicals, fertilizer, chemicals,
urea-formaldehyde foam insulation, asbestos or other potentially hazardous
materials may affect the value of the property. This could include substances in
both the buildings and/or soil. This business enterprise is involved in grain
handling activities. The appraiser assumes that there are no hidden or
unapparent conditions including any environmental contamination of the property,
subsoil, structures or production equipment and machinery that would render it
more or less valuable. The appraiser accepts no responsibility for any condition
regarding any environmental hazard, which may impair the value of the property.
If the property were contaminated, the reported conclusions in this report could
require an adjustment to consider the change. An independent audit of any
environmental concerns should be conducted by an appropriately qualified
inspection company.

                   AMERICANS WITH DISABILITIES ACT (ADA)

The Americans With Disabilities Act (ADA) became effective January 26, 1992. The
appraiser has not made a specific compliance survey and analysis of this
property to determine whether or not it is in conformity with the various
detailed requirements of the ADA, nor is this appraiser trained in the
implications of this act upon these types of agribusinesses. It is possible that
a compliance survey of the property, together with the detailed analysis of the
requirements of the ADA, could reveal that the property is not in compliance
with one or more of the various requirements of the act. If so, this fact could
have a negative impact on the value of the property. Since the appraiser has no
direct evidence relating to this issue, possible noncompliance with the
requirements of ADA in estimating the value of the property has not been
considered.

VOLGA, SOUTH DAKOTA


                                 SITE VALUATION

In estimating site value, the subject property's sites are compared with other
sites in order to estimate the value of the site as if vacant and ready for
development.

Four sales have been found in the immediate area of the subject property. Two of
these sales involve portions of the subject property. These sales have occurred
from 1993 through 2000. They have ranged from $3,497 per acre to $32,988 per
acre for a commercial piece used for a branch bank. Sale No. 1 was for a
C-store/gas station site, thus the higher price per acre. It is my opinion that
sites such as the subject adjacent to railroad and highway are available in
other communities in a range of $5,000. In many areas where there are industrial
parks and communities looking for jobs, site values can be relatively low as an
incentive to attract new business. Therefore, it is my opinion that if the site
were vacant and ready for development $5,000 per acre is its estimate of market
value.

In the Cost Approach, the value of a property is reflected by developing the
Reproduction Cost or Replacement Cost New, deducting the observed depreciation,
and adding the value of the land. Reproduction and/or Replacement Costs have
been estimated through the use of the Marshall Valuation Service (M.V.S.);
suppliers and contractors in the industry (Suppliers) and actual construction
costs times current multipliers.

Physical depreciation is a loss in value due to physical deterioration.

Functional obsolescence (depreciation) is the loss in value due to lack of
utility or desirability of part or all of the property. Thus, a new structure or
piece of equipment may suffer depreciation when built.

External (economic) obsolescence (depreciation) is the loss in value due to
causes outside the property and independent of it.

Reproduction Cost versus Replacement Costs:
- -------------------------------------------
Reproduction cost is the dollar amount required to construct an exact duplicate
of the subject property at current prices.

Replacement cost is the dollar amount required to construct a facility having
the same utility.

Whenever possible, the Cost Approach is based on Reproduction Cost.

Several New Construction Cost Comparables are included on the following pages.

                           NEW COST COMPARABLE SUMMARY

There are six new cost comparables on the construction of soybean processing
plants. These have ranged from a time period from 1991 through 1996. They have
been inflation adjusted to 2001. Excluding an oil refinery and related grain
assets, the new cost comparables indicate mill processing equipment can be added
in the range of $14,461 per ton to $15,750 per ton of productive capacity. One
of the most recently completed plants in the United States is at Volga, South
Dakota (subject property) with completion in the late summer of 1996. The
proposed cost of this facility from the ground up, including land cost and all
infrastructure including grain assets and related crushing mill assets, was
$21,333 per ton of productive capacity based on its original size of 1,500 TPD.
It was subsequently upgraded to a 2,400 TPD plant with a reported cost of $42.0
million, which was $17,500 per ton of capacity.

Based on my analysis of the subject property in the Cost Approach, it has an
estimated reproduction cost new in 2001 of $43.399 million / 2,400 TPD = $18,083
per ton of capacity. It is my opinion that this is in line with the information
extracted from subject and the new cost comparables.

                        NEW CONSTRUCTION COST COMPARABLE

Location:                           Seymour, Indiana

Year Built:                         1992

Name:                               Rose Acre Farms

Type:                               Soybean crushing facility

Description:                        This is a cost comparable on a 500 ton
                                    per day soybean crushing facility
                                    finished in 1992.  It was constructed
                                    on land originally owned by the owner
                                    since 1964 with some ancillary
                                    facilities dating back before the
                                    plant was built in 1992.

                                    Excluding land, the total cost was
                                    $13,024,000. Adjusting some of the older
                                    facilities to the same time period (1992) as
                                    the construction of the plant, the total
                                    cost would have been projected at
                                    $13,190,000. This included a complete
                                    facility and related equipment.

Analysis:                           The total new cost for this plant, as
                                    of 1992, including all of the grain
                                    related infrastructure was estimated
                                    at $13,197,000 divided by 500 tons per
                                    day equals $26,394 per ton of
                                    productive capacity.

Location:                           Council Bluffs, Iowa

Year Built:                         1996

Name:                               Bunge Corporation

Type:                               A new soybean processing plant from
                                    the ground up.

Description:                        This was the construction of a new soybean
                                    crushing facility from a "greenfield"
                                    location with all infrastructure with a
                                    reported crush capacity of 4,110 tons per
                                    day.  It also included a vegetable oil
                                    refinery.  Announcements for the
                                    construction of the plant occurred in
                                    May 1996.  It was operational in 1999.

Analysis:                           Reported costs for this plant are $100
                                    million less $8 million to expand an
                                    existing rail line.

Indications:                        $92 million divided by 4,110 TPD equals
                                    $22,384 per ton of productive capacity,
                                    including a refinery.

Type:                               A new soybean crushing facility from the ground up.

Description:                        Construction was completed in the late summer of
                                    1996 of a new 1,500 ton-per-day soybean crushing
                                    facility from a "greenfield" location.  This was the
                                    cost estimate for  the ground up construction of the
                                    entire facility.  The projected costs were broken out
                                    into the following categories:

                                        Land:                    $  0.50 million

                                        Contingency Funding:        1.5
                                                                 ------
                                                                 $ 31.9  million


                                    This did not include any construction interest costs.
                                    Reported information is that the plant cost $32.5
                                    million to complete.

Analysis:                           Therefore, $32.0 million divided by 1,500 TPD equals
                                    $21,333 per ton of productive capacity.  This plant was
                                    expanded to 2,400 TPD at an additional cost.

Type:                               Soybean crushing facility

Description:                        This is the construction of a new from the ground
                                    up 1,654 ton per day (1,500 metric tons) soybean
                                    crushing facility.  This plant is located adjacent to
                                    Cargill's corn syrup distribution center.  The
                                    original design of the facility would permit
                                    expansion to accommodate 3,000 metric tons per
                                    day.  Cargill said it would build on its customer
                                    relationships that already exist and sell oil from this
                                    plant to major refiners in Central Mexico.  The meal
                                    will be marketed for use in the feed industry.

Analysis:                           The reported new construction costs are $30 million
                                    for a plant capable of processing 1,654 (short) tons
                                    per day.

                                    $30 million divided by 1,654 tons per day equals
                                    $18,138 per ton of productive capacity.

Type:                               Soybean crushing plant

Description:                        This is the reported cost on a new soybean crushing
                                    plant built adjacent to existing grain facilities
                                    owned by Consolidated Grain and Barge.  The facility
                                    is located at the Indiana Port Commission's Southwind
                                    Maritime Center on the Ohio River.  It is adjacent to
                                    an existing grain terminal.  This plant has a reported
                                    crushing capacity of 2,000 tons per day for the production
                                    of soybean meal and crude, degummed soybean oil. Younglove
                                    Construction Company of Sioux City, Iowa, is the General
                                    Contractor and the process equipment supplier is Crown
                                    Ironworks of Minneapolis, Minnesota.  Total reported
                                    construction cost is estimated at $25 to $30 million.

Analysis:                           This is the reported construction cost of the new soybean
                                    processing plant excluding any related grain terminal assets.

                                    Based on the low side estimate of $25 million divided by 2,000
                                    tons per day equals $12,500 per ton of productive capacity.

                                    Based on the high side estimate of $30 million divided by 2,000
                                    tons per day equals $15,000 per ton of productive capacity.

                                    oil mill.  The preparation area consisted of a pre-engineered,
                                    metal frame building with metal sidewalls and metal roof
                                    built new in 1991.  It measured 49' by 79' with 45'
                                    sidewalls, and 30' by 47' with 16' foot sidewalls containing
                                    a total ground floor of 5,281 sq. ft., more or less.

                                       3 - Ross 14" by 45" flaking mills
                                    Total construction cost for this area was
                                    approximately $2.0 million.

                                    The extraction plant consisted of a solvent extraction
                                    process for the extraction of soybean oil and meal on a
                                    continuous flow process designed by DeSmet. It consisted of a
                                    unit with a rated capacity of 500 tons per day, or 16,667
                                    bushels, more or less. It was relocated to the site in 1991.
                                    This extractor was housed in a pre-engineered metal building
                                    with metal frame and metal sidewalls which was open on two
                                    sides. The overall structure measured 34.5' by 93.5' with 45'
                                    sidewalls, containing a total ground floor or 3,226 sq. ft.,
                                    more or less. The meal was dried in a DTDC drying process.
                                    Also located adjacent was an additional pre-engineered metal
                                    frame building with metal sidewalls and metal roof. It
                                    measured 12' by 30' containing a total of 360 sq. ft., more
                                    or less. Located in this building was an auxiliary power
                                    control unit containing an 800 KW capacity generator.

(continued)

                                    There was an outside exposed cooling tower to cool process
                                    water that measured 9' by 18.5'. There were also two 12,000
                                    gallon capacity underground hexane storage tanks and an
                                    associated wastewater separation unit for facility wastewater
                                    treatment. The entire extraction area was complete with the
                                    necessary process equipment and controls for solvent
                                    extraction method of soybean processing. The total cost for
                                    this area was approximately $4.0 million.

                                    Due to the explosive nature of the products involved in this
                                    process, the fire control system consisted of a pre-engineered
                                    metal frame building, 20' by 36' containing a total of 720
                                    sq. ft., more or less. Located within this building was a
                                    Detroit diesel engine fire pumping system manufactured by
                                    Firetrol, Inc., of Gary, North Carolina. Associated with this
                                    area was an earthen pit holding water for fire control
                                    purposes. Total cost of this area was $125,000.

                                    The oil storage area consisted of on-site soybean oil storage
                                    in six aboveground storage tanks with total storage capacity
                                    of 130,000 gallons, more or less. The cost of this area was
                                    $55,000.

                                    The total estimated cost of this plant, excluding any grain
                                    related handling equipment, was $6,180,000 in 1991.

Analysis:                           The total cost, new, for this project in 1991 excluding any
                                    grain processing equipment was $6,180,000 divided by 500 tons
                                    per day equals $12,360 per ton of productive capacity.

                                    The plant was an economic failure at this location. The grain
                                    assets were sold to a competitor and the crushing assets "oil
                                    mill" was disassembled and relocated elsewhere.

                                    The reported sale price of the assets at salvage value
                                    was $1.0 million.

Note:
The age life method is the effective age of the plant, either actual or based on
condition, divided by an economic life of 40 years, which is considered typical
for a plant with a high percentage of machinery and equipment. This results in
an estimate of physical and functional depreciation. As an example, 5 years
effective age divided by 40 years economic life equals 12.5%, rounded to 13%.
Economic obsolescence is estimated at 10% based on the historical analysis of
this company from the Income Approach. Economic obsolescence is a factor outside
the property that affects its value. It is usually a lack of volume, gross
margins, expense control, competition or a combination of all of these factors.
Economic obsolescence effects the income statement through lower net operating
income.

VOLGA, SOUTH DAKOTA                                                   APPROACH


                         INCOME CAPITALIZATION APPROACH

The income capitalization approach is a technique in which the anticipated net
operating income is processed at a rate commensurate with the current market
which would attract a prudent owner/operator to this type of investment, whereby
reflecting the value of the investment which produces the income.

The subject property is owned and operated by the South Dakota Soybean
Processors of Volga, South Dakota. Historical income and expense information for
the cooperative for the fiscal years ending August 31, 2000 through August 31,
1996 has been review by this appraiser as well as year-to-date income and
expenses for the period ending June 30, 2001. A projected income and expense
statement has been prepared based on the "typical operator" (no unique
capabilities) concept for this industry. This projected income statement relies
on the following assumptions:

     -   Volume can be sustained at or above 24.6 million bushels per year
     -   Margins are at or above most recent four-year average
     -   Expenses are those typical for the industry and the subject.

The following income analysis, and/or income projection and results thereof are
based upon assumptions believed to be reasonable by MID-STATES APPRAISAL
SERVICES, INC., however, there is no warranty, representation or guarantee of
the reasonableness, accuracy or completeness of any such assumptions,
projections or such analysis or the results thereof. The accuracy and
completeness of the analysis depends upon, and will be affected by, future
events and conditions, including but not limited to the general economic
condition, none of which can be accurately predicted at this time with any
degree of certainty.

Notes
- ------
Reserves have been calculated at one half of depreciation expense. Because of
the intense usage of machinery and equipment reserves are required to maintain
the plant throughout its economic life because of the high wear factor and/or
obsolescence.

Working capital has been estimated at 5% of gross margins based on this
appraiser's experience with other agribusiness properties that borrow all of
their working capital requirements.

Patronage has been adjusted downward (70%) to account for its cash equivalence.
Only 30% patronage is paid in cash. The balance has a very long redemption time.

                            INTEREST RATES AND TERMS

This appraiser has surveyed numerous lenders over the years in regard to their
willingness to provide "typical" financing to the marketplace on special purpose
agricultural properties such as a grain elevator. Typically, these lenders which
would include many national lenders are in the range of prime rate to prime plus
one. The interest rate is somewhat sensitive in regard to the credit worthiness
of the borrower. However, the market as a whole may not all be prime or subprime
borrowers. Therefore, "typical" is assumed to be prime plus one percent.
Amortization schedules also are a variable. Again, in surveying many lenders
many of which are national in scope, this could range from a low of seven years
to a high of 15 years with most typically being in the range of 10 years. With
special considerations, that can be adjusted upward beyond 15 years. However,
this is not considered to be "typical".

With regard to equity dividend rates, the extraction of equity dividend or
overall rates out of comparable sales is very difficult due to lack of
information. Over the years, numerous large clients in their publications and in
conversations with me have indicated what they consider to be the equity
dividend for these types of properties which have significant risk. This has
ranged from a low in some cases of 15% to 20% to a high of 30% because of
significant risks. Therefore, an equity dividend rate of 25% is considered to be
normal. Again, special circumstances, newness of the property, uniqueness of the
territory, market considerations and concentrations could all affect the
prospective of an owner/operator in regard to their equity dividend
requirements.

In discussions over the years with large national owners such as ADM, ConAgra,
Cargill, Inc., Farmland Industries, and Koch Industries, they have agreed that
an overall rate (RO) on an adjusted net operating income before depreciation,
debt service, and income taxes of 18% to 22% is certainly within their realm of
requirements. If interest rates move up, the overall rate moves up. The "Band of
Investment" that follows attempts to show the interaction of mortgage and equity
on a blended basis.

Finally, the value of these special purpose properties (soybean crushing plants)
can be significantly impacted by overall long-term interest rates.

                            BAND OF INVESTMENT METHOD
                 FOR DETERMINING CAPITALIZATION OF EARNINGS


The following band of investment technique demonstrates one method of estimating
the capitalization rate appropriate for the property. The capitalization rate is
based on the rate of mortgage interest available and the rate of return required
on equity.

Example
- -------

               Mortgage                 M                   70%
            +  EQUITY                 + E                +  30%
               --------                 ---                ----
            =  Total Investment         100%               100%

OR:

Rate to Mortgage                RM              Mortgage Constant
Rate to Equity                  RE              Equity Dividend Rate
- ----------------                --              ---------------------------
Rate to Property                RO              Overall Capitalization Rate

The Band of Investment technique is a way to properly weigh the rates.

          Mortgage Ratio x Loan Constant             M x RM
        + Equity Ratio x Equity Dividend Rate        E x RE
          -----------------------------------        ------
        = Overall Capitalization Rate                  RO

Properties are usually purchased with a combination of debt and equity capital.
The overall capitalization rate (RO) must satisfy the market return requirements
for both investment positions. A lender usually anticipates receiving a
competitive interest rate based on the perceived risk of the investment and a
requirement that the loan principal be repaid through periodic amortization,
usually a period of years. Owners/operators (equity investors) anticipate
receiving a competitive equity cash return based on the perceived risk of their
property (business) or they will invest their funds elsewhere. The mortgage
constant is a function of the interest rate, the frequency of the amortization,
and the amortization term of the loan. It is the sum of the interest rate and
the sinking fund factor, which is the amount that it will payoff a dollar over a
period of time. When the terms of the loan are known, the mortgage constant can
be found in financial tables or with a financial calculator. This analysis
assumes the availability of mortgage financing. Therefore, assume that a 70%
loan is available at a 7.75% fixed interest rate (prime rate was 6.75% on June
30, 2001, plus 1.0%) and a 10-year amortization schedule. Furthermore, the
remaining economic life of this property (business) is equal to or in excess of
10 years. Also, owners/operators in this type of property would typically
require a 30% Equity Dividend Rate before taxes because of risks. The indicated
capitalization rate is as follows:

                M x RM       .70 x .1440    =    .1008
                E X RE       .30 x .30      =    .0900
                ------       -------------------------
                RO                          =    .1908


Thus the indicated overall capitalization rate (RO) is estimated to be 19.08%.

Value from the capitalization of earnings will be determined by the Direct
Capitalization Technique. Net operating income before depreciation, debt service
and income taxes is capitalized by using the formula of:

               Income
               ------  =  Value
                Rate

                  VALUE BY DIRECT CAPITALIZATION TECHNIQUE

                                     SUMMARY

The most recent 3.83 years of financial information has been analyzed by this
appraiser. Adjustments have been made to the operating statement to account for
all interest expense and all depreciation expense. This has resulted in an
addition to net income. Subtractions have been made in the areas of reserve for
wasting assets since this facility is a processing plant with more than half of
its value made up in machinery and equipment. There is a substantial amount of
obsolescence, wear and tear that occurs in this type of equipment over years.
Therefore, reserves must be maintained in order to keep the plant at essentially
the same operating level through its economic life. Also an estimate for working
capital expense has been made based on the business having no "free" working
capital on its balance sheet and borrowing all of its working capital needs.
This has been estimated at 5% of gross margins based on the appraiser's
experience of plants in the agribusiness industry. Patronage accrued has been
adjusted downward (70%) to account for its cash equivalency. Only 30% of the
patronage is paid in cash. The balance has a very long redemption time.

These total adjustments are then added to or subtracted from the stated net
income to arrive at an adjusted net operating income before depreciation, debt
service, and income taxes. This historical 3.83 year average is $6.165 million
dollars (rounded). This industry does have significant changes in its net income
over time because of the volatility in the pricing of its commodities which are
all involved in a world marketplace. Thus, the 3.83 average is considered to be
the best indicator of its near term future.

                            SALES COMPARISON APPROACH

The Sales Comparison Approach is the comparison of like or similar properties
that have sold in comparison to the subject property.

In the appraisal of any income producing property, the analysis of known sales
of comparable properties is generally one of the most reliable tools available
to the appraiser in the formation of his opinion of value. Under the Principle
of Substitution the value of any item cannot reasonably be considered to be in
excess of the amount of money for which an equal or equivalent property can be
acquired.

One means of comparing soybean processing plants is on a dollars per ton day of
crushing capacity (TPD), with the differences reflected as upward or downward
adjustments for dissimilar characteristics. This section contains sales
information or comparisons of soybean crushing facilities. Obsolescences,
functional and economic (external), are also taken into consideration. All of
these factors are an integral part in arriving at our estimate of value of the
subject property.

Exactly what proportion of value relates to the subject facility's management
would be difficult to estimate. Any appraisal of operating properties such as
the subject business must assume reasonably efficient management ("typical
operator") of the operation, as well as maintenance of the property unless
otherwise noted.

                                     EXAMPLE

If a facility sold for $15,000,000 and it had 1,000 tons per day (TPD) of
crushing capacity, it sold for $15,000 per ton of crushing capacity.

Condition:                          Fair

Comments:

*This was part of a multi-plant sell-off by A. E. Staley to Archer Daniels
Midland Company. The sale price of $75 million also included a soybean oil
refinery in conjunction with the Des Moines, Iowa, processing plant. The
refinery has a capacity of approximately 18 cars (60,000 lbs.) per day. It has
an estimated contribution in the sale of $10 million to the total. The sale
price did not include the Mexico, Missouri, facility which was a 1,500 TPD plant
which was part of a separate consideration in a lease agreement. This plant was
on an industrial revenue bond or lease and was not considered in the overall
purchase. Also, there was an additional A. E. Staley plant at Decatur, Illinois,
which was part of another agreement which was later demolished. This sale
indicates that the soybean processing operation sold for approximately $65
million for 6,900 tons of processing capability or $9,420 per TPD of productive
capacity. Verification of this information was from a competitor involved within
the industry at the time of the sale of these plant. Further research indicates
that the reported sales price on the Des Moines, Iowa, plant by itself without
any consideration to value allocation to the other plants was $32.5 million.
Based on the discussion previously of a $10 million contribution for the
refinery, this leaves a remainder of $22.5 million for 3,000 TPD or $7,500 per
TPD for Des Moines.

Comments:                           According to a knowledgeable source,
                                    this plant was reportedly sold at a
                                    premium price because of its strategic
                                    location and fit into the market
                                    place.  It was probably sold somewhat
                                    near its replacement cost new.  But,
                                    because of its location and history as
                                    a viable competitor in the crushing
                                    industry it commanded a good price.
                                    The facility was equipped with two
                                    Crown 1500 TPD extractors located side
                                    by side.  The plant was in the process
                                    of gearing up over time to crush 3,000
                                    TPD.  At the time of sale it had 2,400
                                    TPD of productive capacity.  According
                                    to this source, at the time of sale it
                                    was crushing near 20 million bushels
                                    per year with a total operating cost
                                    of approximately $0.39 per bushel, of
                                    which approximately $0.05 per bushel
                                    was depreciation cost.  There were
                                    approximately 70 people on the payroll
                                    for the operation and administration
                                    of the plant at the time of sale.  As
                                    a going concern, the indicated sale
                                    price of this facility is $13,750 per

                                    added around 1985.  The plant was
                                    originally a country grain elevator
                                    location until 1982.  At that time it
                                    was converted into a vegetable oil

                                    was added in 1985 to improve plant
                                    capacity.  The facility has changed

                                    Northwestern Railway Company.  This

                                    North Dumas Milling, Inc.  During its
                                    history this plant has processed
                                    cotton seed, soybean, and corn germ.
                                    After its contract with Coors to
                                    process corn germ expired, the owners
                                    determined that they had neither the
                                    finances nor the expertise to continue
                                    operating the plant.  It was closed in
                                    1989.  It was not an operating plant
                                    at the time of sale.

                                    Roseland, Inc., the current owner,
                                    opened the plant and is currently
                                    crushing oil seeds.  It is the only
                                    oil seed crushing plant within 350
                                    miles and it is attempting to
                                    participate in a niche market.

Indications:                        $500,000 divided by 120 TPD equals
                                    $4,167 per ton of productive
                                    capacity.

                                    $31.75 million - $7.5 million = $24.25
                                    million / 2,000 tons per day = $12,125 per
                                    ton of crush capacity.

SOUTH DAKOTA SOYBEAN PROCESSORS                               SALES COMPARISION
VOLGA, SOUTH DAKOTA                                                    APPROACH


                           COMPARABLE SALES CONCLUSION

This appraiser has researched the market and found 11 sales that have occurred
in a time period from 1984 through 2000. The sales that occurred in the industry
in the mid-1980's were during a time period of low net operating incomes and
severe financial pressures in the soybean crushing industry. This resulted in
consolidation of the industry into larger, potentially more efficient,
operations. The late 1980's through the mid-1990's was characterized by higher
crushing margins in the industry. The sales that have occurred in the 1990's at
Guntersville, Alabama, and Goodland, Kansas, Chesapeake, Virginia, and Enderlin,
North Dakota indicate a substantially higher price. The recent sales at these
four locations have occurred in a price range from $12,125 per ton of productive
capacity to $17,672 per ton of productive capacity. The plants at Goodland,
Kansas and Enderlin, North Dakota, are sunflower crushing plants; however, they
have all the physical internal and external capabilities of a soybean crushing
plant. They are dedicated to the crushing of sunflowers which is also an oil
seed crop. An interesting note on the Goodland, Kansas, sale is that this was a
leased fee estate sale. The original developer of the property had operated it
for approximately two years, then leased the facility to ADM and later sold its
leased fee estate to a bank as a trustee for an undisclosed third party. A lease
still remains on the facility with ADM as the operator. This Leased Fee Estate
sold for a reported $17,672 per ton of productive capacity for a smaller 500 TPD
plant. The facility at Guntersville, Alabama, sold as a Fee Simple Estate with a
Business Enterprise in it for $13,750 per ton of productive capacity. The sale
at Enderlin, North Dakota, in 1996 was also a sale/lease purchase. It sold for
$15,542 per ton of crushing capacity after removal of the refinery contribution.
Chesapeake, Virginia is a sale in 2000 that after removal of non-crushing assets
that sold for $12,125 per ton of crushing capacity.

The overall average of the four most recent sales is $14,750 per ton of crush
capacity (TPD). Considering the newness of the subject to the comparables and
its location in a good production area, a slight positive adjustment is
considered relevant. However, considering the recent economic downturns in the
industry in the last year and the closure of other plants in the United States
that were less economically viable, there is a continued risk in this market.
This would account for a slight negative adjustment. In my opinion, these
adjustments cancel each other out. Therefore, the average of the four most
recent sales is considered the most reasonable.

Therefore, based on the information available from the soybean crushing sales,
it is my opinion that the market value of the subject property which includes
land, buildings, improvements, rolling and portable equipment as an operating
unit, was $14,750 per ton of crushing capacity. Therefore:

Market Value Estimate (Total)12                  $ 33,900,000

Estimated Contribution of Existing Personal
Property (rolling and portable equipment)
included in the above total                      $    410,000 (rounded)

Estimated Contribution of Real Estate
Components and Going Concern Value               $ 33,490,000

                              MARKET VALUE ESTIMATE

The differences in the values above are due primarily to the area of emphasis on
the approach. The Cost Approach is reproduction or replacement cost new less
estimated depreciation in all forms. The Income Capitalization Approach analyzes
profitability and return on investment and the Sales Comparison Approach is a
comparison of comparable sales with allowances for dissimilar characteristics.

South Dakota Soybean Processors of Volga, South Dakota, owns and operates a
2,400 TPD soybean processing plant. It does not have an edible oil refinery
included in its operation. This requires the plant to sell its oil to a refiner
for further processing. This is typical of many soybean processing plants. The
facility is in near new condition (built in 1996). All three approaches have
been considered in this value conclusion. Based on indications from the Income
Capitalization approach, there is external obsolescence, which is a factor
outside the property that affects its value. It is usually a lack of volume,
gross margins, expense control, competition, or combinations of all these
factors. The most emphasis to value has been placed on the Cost and Income
Capitalization Approaches.

Based on my investigation and analysis of the data gathered, I have formed the
opinion that the Market Value of the subject property which includes the
business enterprise, fee simple estate, leasehold estate (if any), buildings,
improvements, rolling and portable equipment "as is" free and clear of any liens
as outlined in the enclosed report as of June 30, 2001, was a total of
Thirty-Three Million Nine Hundred Thousand Dollars ($33,900,000). The
contribution of personal property (rolling and portable equipment) was estimated
at Four Hundred Ten Thousand Dollars ($410,000). The contribution of the fee
simple estate and leasehold estate (if any) which includes the going concern
(business enterprise) was estimated at Thirty-Three Million Four Hundred Ninety
Thousand Dollars ($33,490,000).

</Table>


An additional question has been asked of this business appraiser in regard to
valuation of certain other assets listed above. Based on my experience in the
business appraisal area, the column labeled "Current Market Value" is my
estimation of the market value of these assets by category. CoBank patronage is
discounted to a net present value based on a 15 year payout and a 12% rate of
return. This soybean processing business has an overall rate requirement in the
range of 19% to justify its values. However, the stock market has been capable
of returning in the range of 11% to 12% over time. Thus, the reason for the 12%
discount.

The Harvest States patronage of $3.25 million has an extremely long redemption
window. On that basis, it has been my experience that this type of stock,
similar to Farmland Industries, has traded in the range of near nothing to
upwards of 10% of its face value. Thus, 5% of its face value has been allocated
as its current market value.

The 4% investment in USSC stock is in a company that has not generated a profit
and is still in the conception/startup stages. It is very similar to "dot com"
with the substantial failures that have occurred in that industry. Thus, only a
minimal value of $10,000 has been allocated to that investment.

The accrued patronage on Harvest States for the current year of $972,250, if it
comes to fruition Harvest States pays 30% in cash. Thus, the face value of this
has been discounted to its cash value equivalent of 30%.

Therefore, the total estimated current market value of these other assets was
$522,133, rounded to $520,000.

ADDITIONAL DISCUSSION - continued

A further question was asked by the management of South Dakota Soybean
Processors in regard to the potential discounts for lack of marketability and
minority stock if the cooperative were to sell its stock. This cooperative is
owned by patrons/shareholders with no one owning control. It is considered to be
a closely held corporation and its stock would suffer from discounts for lack of
marketability and minority issues.

A discount for the lack of marketability has been recognized by courts,
valuation experts, and the IRS as a cost inherent in stock companies in which
there is no ready market for the shares. Usually, the discount for lack of
marketability is tied to the expectation of how long it will take to convert the
business interest into cash. The items that may affect the size of a
marketability discount include:

        -   Size of the interest.
        -   Financial condition of the company.
        -   Limited market for the stock
        -   Dividends paid by the company.

South Dakota Soybean Processors has paid dividends to its shareholders. This
dividend has fluctuated over time. Also, current stockholders must be
"producers" and owning stock has a delivery requirement on soybeans. Excluding
the special nature of current ownership and considering the market as a whole,
this company's stock would suffer from a lack of marketability.

There have been many studies on the lack of marketability discounts.
Collectively, these studies have shown over time a mean discount of up to 32.6%
for lack of marketability.

In an article written by Bruce Johnson, ASA, appearing in the March 3, 1999
edition of BUSINESS VALUATION, he writes that in many cases, discounts for lack
of marketability in business appraisals rely at least partially on studies of
restricted stock transactions. The inability to sell a minority interest in a
company increases an investors exposure to changing market conditions and
increases their risk of ownership. The reason for lack of marketability is to
recognize and quantify the effective value. Revenue Ruling 77-287 recognizes a
need for a discount in the lack of marketability for an interest in a privately
held company. He reports of several studies on restricted stocks that have been
conducted since the beginning of 1960's. The average or median discount for lack
of marketability found in these previous studies has ranged from 23% to 45%.
Two-thirds of the studies performed found the average or median discount to be
31% and 36%. Specifically, Mr. Johnson quotes a study performed by William
Silber published in the FINANCIAL ANALYST JOURNAL. This study reported that the
discounts ranged from a premium of 13% to a discount of 84% with an overall
average discount of 34%. In summary, certainly the lack of marketability can
have a significant impact in regard to selling of an unlisted stock. A minority
position presents an equally challenging area.

                          MINORITY DISCOUNT DISCUSSION

A minority interest discount can be summed up under a discussion called "lack of
control". This is a situation less than 51% of the stock has limited to no
control; thus, causing a minority situation. The discounts for minority purposes
are above and beyond discounts for lack of marketability. The concept of
non-controlling ownership interest deals with a relationship between the
ownership interest being valued in a total business enterprise. The concept of
marketability deals with the liquidity of the subject's ownership interest,
i.e., how quickly it can be converted to cash. These discounts have an
intertwining relationship. It is my opinion in a minority situation discounts by
themselves ranging upwards to 30% would not be considered unusual.

Furthermore, this appraiser has gathered information on a closely held
corporation involved in agribusiness that has repurchased minority stock over a
period of years. A summary is included herein in this report. The company's name
has been eliminated to protect the confidential nature of the clients. However,
these clients have agreed to allow this information to be disclosed as long as
their company names and locations are held by this appraiser in a confidential
basis.

The treasury stock purchases by Company No. 1 are summarized on page 102 with a
table. The actual repurchases of stock over time by this closely held company
provide actual evidence that this company itself recognizes the lack of
marketability and minority discounts within its own transactions. The discounts
collectively could be summarized between 50% and 75% in a time period from 1990
through 1995. The exact allocation between lack of marketability and minority
discounts is not distinguished in the overall purchases. However, the market
itself does recognize these two discounts to be somewhat separate and distinct.
However, in the sale of stock of closely held corporations, no distinction is
usually made, and it is usually lump-summed into a single discount.

In Company No. 2, stock was purchased by other stockholders in this closely held
company. This is summarized on page 103. Based on the stockholders equity for
the year ending, the discounts from net book value per share ranged between
79.56% to 82.44%, which is accumulative discount for lack of marketability and
minority discounts.

                                     SUMMARY

Finally, these discounts must then be utilized in the final valuation of the
stock. A new balance sheet is usually prepared taking the assets to market value
and this adjusted stockholders equity is then subject to the lack of
marketability and minority discounts. These discounts are taken sequentially,
one after the other, on a stair step basis. Thus, the estimated market value of
the shares to be valued are subject to the lack of marketability discount
estimate. The remainder is then subject to a minority discount estimate, which
leaves a remaining value which is the estimation of market value of the subject
stock after all necessary steps in regard to valuation have been considered.
With the marketability and minority discounts taken sequentially, the total
discounts are then a lump sum estimate of the total discount from the starting
value on the subject stock.

                            GOING CONCERN DISCUSSION

The last question asked of this appraiser was my opinion in regard to "going
concern value". The subject property has a tax depreciated book value
substantially less than the current estimate of market value of the business
enterprise as a whole. It is my opinion that the difference between tax
depreciated book value of the assets (business) and the market value estimate of
the assets (business) is considered the going concern value.
