RE:  Complete Appraisal, Self-Contained Report
     Leasehold Going Concern Market Value Analysis
     Proposed 40 Million Gallon Ethanol Fuel Plant to be known as "Northern
     Lights Ethanol"
     48416 144th Street, Big Stone City, SD 57216
     Owner/Borrowers: Northern Lights Ethanol, LLC
     RETECHS Project #CCV-01-06 ROC

Dear Mr. Edstrom:

This COMPLETE APPRAISAL presented in a SELF-CONTAINED REPORT was made in
accordance with your request to develop an opinion of the above captioned
property's leasehold market value in its (1) as-is condition and (2) upon
completion of construction. Typically, the market value of real estate assumes
FEE SIMPLE estate or ownership, often referred to as absolute ownership. It
implies that a property is free of encumbrances or restrictions that would
affect ownership or title. In this particular property, the owner/borrower or
Northern Lights Ethanol, LLC will have ownership in only the completed subject
improvements as the improvements will be located on a site leased from Big
Stone-Grant Industrial Development & Transportation, L.L.C. This land or site
lease is relatively long term (total term of 99 years) and, as the following
report will detail, the specified lease terms have not created a marketable
interest by Northern Lights Ethanol, LLC. Therefore, the owner/borrower will
have only a leasehold interest in the completed subject improvements.

The property's valuation analysis also considered its "going concern" value
concept. This concept, normally created by a proven on-premise business
operation, is a value enhancement resulting from items of intangible personal
property such as marketing and management skills, an assembled work force,
working capital, etc. A profitable ethanol plant, a characteristic that should
be anticipated in the completed property's operation, is or would be purchased
with this going concern value concept incorporated within the transaction. Based
on the preceding, the primary appraisal objective is then to provide an opinion
of the completed subject improvement's LEASEHOLD GOING CONCERN MARKET VALUE. The
appraisal's intended use is to assist you and/or your assigns in loan
underwriting purposes. The appraisal report is NOT intended for any other use or
user.

The description of the subject property, the data and detailed analyses of all
factors pertinent to the development of the appropriate value(s), and ALL
definitions, assumptions, and limiting conditions are detailed in the enclosed
report. In particular, your attention is directed to the following important
limiting conditions:

1.   This letter of transmittal does NOT represent the fully documented
     appraisal of the subject real estate. Sole reliance by the reader on the
     contents of this letter without considering the entire contents of the
     appraisal report (starts with this letter of transmittal and concludes with
     page 128) could lead the reader to erroneous conclusions concerning the
     appraisal of the subject property. Therefore, this letter must not be
     utilized in place of nor represented as the complete appraisal report.

<Page>

Mr. Robert J. Edstrom                 -2-                       November 9, 2001

2.   The completed appraisal was made to conform to the Appraisal Institute's
     Code of Professional Ethics and Standards of Professional Appraisal
     Practice and the most recent edition of the UNIFORM STANDARDS OF
     PROFESSIONAL APPRAISAL PRACTICE (USPAP) adopted by the Appraisal Standards
     Board of the Appraisal Foundation and should meet the minimum requirements
     for all federally related transactions. Additionally, the appraisal was
     made in conformance with OCC-12CFR 34, Subpart C; FDIC-12 CFR 323; Title XI
     of FIRREA; and "U.S. Bank Commercial Reporting Guidelines", dated February
     1, 2000.

3.   It will be assumed that the proposed ethanol plant will be completed per
     plans and specifications provided by the owner/borrower, as detailed in
     this report. Any significant deviation from the plans and specifications
     could render the appraisal and its results void. Likewise, the as-complete
     value is based on a prospective or future date or the date the proposed
     improvements are scheduled for completion. This assumption is deemed an
     "EXTRAORDINARY ASSUMPTION", or by USPAP definition: "AN ASSUMPTION,
     DIRECTLY RELATED TO A SPECIFIC ASSIGNMENT WHICH, IF FOUND TO BE FALSE,
     COULD ALTER THE APPRAISER'S OPINIONS OR CONCLUSIONS." For the purpose of
     this analysis, it will be assumed that market conditions relating to this
     particular property type or that of an ethanol plant would remain unchanged
     through the prospective completion date. This extraordinary assumption is
     clearly required for purposes of reasonable analysis within the appraisal's
     objective(s) and intended use. Use of this extraordinary assumption still
     results in a credible analysis.

4.   A "Phase I Environmental Property Evaluation" was completed on the subject
     site by American Technical Services, Inc (ATS). of Sioux Falls, South
     Dakota, dated May 2, 2001. The report's cover letter, states that "BASED ON
     THE DESCRIBED ENVIRONMENTAL PROPERTY EVALUATION, ATS CONCLUDES THAT NO
     FURTHER SITE ASSESSMENT ACTIVITIES ARE NECESSARY AT THIS TIME. Based on
     this environmental evaluation, it will be assumed that no environmental
     concerns exist within the subject site.

5.   The Americans with Disabilities Act (ADA) became effective January 26,
     1992, or before the proposed subject improvements are scheduled to be
     completed. Therefore, it can only be assumed that the completed subject
     improvements will meet all of the ADA requirements.

6.   The appraisal assignment is based on an impartial or unbiased perspective;
     it is not made for the purpose of favoring a specific cause or any
     particular party. The undersigned has no present or contemplated future
     interest in the real estate that is the subject of this analysis and all
     opinions were developed through the course of accepted analytical
     procedures. Therefore, neither the employment to make the analysis nor the
     compensation is contingent on the outcome of the analysis directly related
     to the appraisal's intended use.

7.   It is assumed that ALL information provided by the owner/borrower, their
     representatives, and various market participant verification sources is
     accurate and that no misrepresentations have been made. This assumption is
     especially pertinent as considerable information was owner/borrower
     provided pertaining to the subject property's projected plant production
     and income and expenses.

8.   The subject property's developed leasehold market value opinion is based on
     a reasonable exposure time (the time needed to market the subject property
     PRECEDING the appraisal's effective date) of one-two years. A reasonable
     marketing period (assumes a sale AFTER the appraisal's effective date) was
     also estimated at one-two years. The market value opinion is a nominal or
     gross value; no adjustment has been made for carrying costs or the time
     value of money which may be incurred over time if the real estate is
     marketed.

Mr. Robert J. Edstrom                 -3-                       November 9, 2001

Careful consideration has been made to the valuation methods employed and to an
accurate analysis of the subject property and its related market. Based on the
results of the appraisal investigation and analysis, it is my opinion that the
subject improvement's respective values are:

<Table>

                                                             
     Objective #1:  Subject Improvement's  PROSPECTIVE
                    AS-COMPLETE LEASEHOLD GOING CONCERN
                    MARKET VALUE, as of November 1, 2002, or
                    the date the improvements are scheduled
                    for completion:                                $50,000,000

     Objective #2:  Partially built improvement's AS-IS leasehold
                    market value as of September 17, 2001, or
                    the appraisal inspection date:                 $10,000,000
</Table>

The concluded going concern market value includes the contributory value of the
(1) improvements (site is excluded as it is subject to a long-term lease) AND
(2) the contributory value of the non-real property items or furniture,
fixtures, and equipment (FF&E), personal property, trade fixtures, and all other
intangible items used in the complete operation of an ethanol plant such as
marketing and management skill, assembled work force, working capital, etc.
Ethanol plants are unique real estate investments since their ability to
generate revenue depends on more than simply real estate. An ethanol plant
simply cannot operate without the inclusion of non-real property items and
reasonable and competent management must be assumed. The UNIFORM STANDARDS OF
PROFESSIONAL APPRAISAL PRACTICE (USPAP) dictates that the appraisal must
"IDENTIFY AND CONSIDER THE EFFECT ON VALUE OF ANY PERSONAL PROPERTY, TRADE
FIXTURES, OR INTANGIBLE ITEMS THAT ARE NOT REAL PROPERTY BUT ARE INCLUDED IN THE
APPRAISAL". Therefore, the following allocation of the leasehold going concern
market value has been made for the purpose of this appraisal:

<Table>
<Caption>
                                                        Leasehold Going Concern
                                                        Market Value Allocation
            Components                                         11-1-2002
            ----------                                         ---------
                                                           
        a.  Improvements Only                                 $30,000,000
        b.  Non-Real Property Items to include
            going-concern (FF&E, personal
            property, etc.)                                   $20,000,000
                                                              -----------

             Total                                            $50,000,000
</Table>

Again, these are value ALLOCATIONS. They do NOT represent individual values for
each component but, rather, it is their estimated contributory value to the
total going concern value conclusion.

It has been a privilege to be of service. If you have any questions or comments
after reading the appraisal report, please inquire. (The only computer software
used in this appraisal is Microsoft Word 97. No computer software was used in
the ANALYSIS of the property.)

Respectfully submitted,

B.   ASSUMPTIONS AND LIMITATIONS OF THE APPRAISAL

     This appraisal report is subject to the limiting conditions:

 1.  No responsibility is assumed for the legal description or for matters
     including legal or title considerations. Title to the property is assumed
     to be intact and marketable and free and clear of any or all liens or
     encumbrances unless otherwise noted. Special assessments have been
     addressed in the appraisal report.

 2.  Responsible ownership and competent property management are assumed.

 3.  The information furnished by others is believed to be reliable. However, no
     warranty is given for its accuracy.

 4.  All engineering is assumed to be correct. The report's plat maps, plans,
     and all other illustrative material are included only to assist the reader
     in visualizing the property.

 5.  It is assumed that no hidden or unapparent conditions exist in the
     property, subsoil, or structures that render it more or less valuable. No
     responsibility is assumed for such conditions or for arranging for
     engineering studies that may be required.

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

 7.  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.

 8.  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.

 9.  It is assumed that the utilization of the site and improvements is within
     the boundaries of the property described and that no encroachment or
     trespass exists unless noted in the report.

10.  While the Appraiser has inspected the subject property and has considered
     the information developed in the course of such inspection together with
     the information provided by the ownership and client, the Appraiser is not
     qualified to verify or detect the presence of hazardous substances or
     environmental liabilities by visual inspection or otherwise, nor qualified
     to determine the effect, if any, of known or unknown substances or
     liabilities present. Unless otherwise stated in the report, the final
     conclusion of value is based on the assumption that the subject property is
     free of hazardous substances, hazardous waste contamination, and all other
     environmental liabilities, and it is specifically assumed that present and
     subsequent ownerships will exercise due diligence to ensure that the
     property does not become otherwise contaminated.

11.  The appraisal and market value estimate is based on cash, its equivalent,
     or on financing terms available for the property type in its locale as of
     the effective appraisal date. No consideration has been given to the
     assumption of favorable existing financing (if any) or favorable
     seller-financing.

12.  The distribution, if any, of the total valuation between site and
     improvements applies only under the stated program of utilization. The
     separate allocations for site and improvements and any other value
     components must not be used in conjunction with any other appraisal and are
     invalid if so used.

13.  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 with proper written qualification and
     only in its entirety.

14.  The appraiser herein by reason of this appraisal is not required to give
     further consultation, testimony, or be in attendance in court with
     reference to the property in question unless arrangements have been
     previously made.

15.  The forecasts, projections, or operating estimates contained herein are
     based on current market conditions, anticipated short-term supply and
     demand factors, and a continued stable economy. These forecasts are,
     therefore, subject to changes with future conditions.

16.  Unless specifically cited in the appraisal report, no value has been
     allocated to mineral rights or deposits.

17.  Unless otherwise addressed within the appraisal report, no consideration
     has been afforded to any potential Natural, Cultural, Recreational, or
     Scientific value that may or may not be inherent to the subject property.

       development with unsold units.                                                 108-109

  10.  There must be a statement in the certification that the appraisal
       assignment was not based upon a requested minimum valuation, a specific
       valuation, or approval of any proposed financing.                                    8

  11.  There must be sufficient documentation to support the appraiser's logic,
       reasoning, judgement, and analysis to enable the client to determine the
       reasonableness of the final market value estimate.                              11-111

  12.  The report must include a legal description of the property in addition
       to the description required by USPAP.                                               14

  13.  Identify and separately value any personal property, fixtures, or
       intangible items that are not real property but are included in the
       appraisal, and discuss the impact of their inclusion or exclusion on               3 &
       the estimate of market value.                                                  102-104

  14.  Follow a reasonable valuation method that addresses the sales comparison,
       income, and cost approaches to market value, reconciles those approaches,
       and explains elimination of each approach not used.                              55&56

                              II. APPRAISAL PROCESS

A.     INTRODUCTION/SCOPE (rev. 8/1/01)

             An appraisal of the subject property is presented in the following
       report; an APPRAISAL is defined as:

             1.   AN ANALYSIS, OPINION, OR CONCLUSION RELATING TO THE NATURE,
                  QUALITY, VALUE, OR UTILITY OF SPECIFIED INTEREST IN, OR
                  ASPECTS OF, IDENTIFIED REAL ESTATE.
                  (Appraisal Institute, THE DICTIONARY OF REAL ESTATE
                  APPRAISAL, THIRD EDITION: 16)

             2.   THE ACT OR PROCESS OF DEVELOPING AN OPINION OF VALUE; AN
                  OPINION OF VALUE.
                  (UNIFORM STANDARDS OF PROFESSIONAL APPRAISAL PRACTICE,
                  2001 Edition)

       An appraisal is based on an impartial or unbiased perspective; it is not
       made for the purpose of favoring a specific cause of any particular
       party. It is essential that the appraisal communicate accurate analyses
       and opinions in such a manner that it will be meaningful to the client
       and not be misleading in the marketplace.

             The UNIFORM STANDARDS OF PROFESSIONAL APPRAISAL PRACTICE (USPAP)
       was developed to reflect the current standards of the appraisal
       profession. These standards deal with the procedures to be followed in
       performing an appraisal; they are referenced throughout the following
       appraisal report. The appraisal process reports the appraisal procedures
       in an orderly manner in which the data used in developing the value(s) of
       the subject property is assembled, classified, analyzed, and interpreted
       into a final opinion or conclusion. The final conclusion of value(s) is
       developed through a course of accepted analytical procedure reflecting
       only the opinion(s) of the appraisers involved in the analysis.

             Standard 1 of the UNIFORM STANDARDS OF PROFESSIONAL APPRAISAL
       PRACTICE (USPAP) states that "IN DEVELOPING A REAL PROPERTY APPRAISAL, AN
       APPRAISER MUST IDENTIFY THE PROBLEM TO BE SOLVED AND THE SCOPE OF WORK
       NECESSARY TO SOLVE THE PROBLEM, AND CORRECTLY COMPLETE RESEARCH AND
       ANALYSIS NECESSARY TO PRODUCE A CREDIBLE APPRAISAL." Two categories are
       allowed in DEVELOPING an appraisal or:

             1.   COMPLETE APPRAISAL: THE ACT OR PROCESS OF DEVELOPING AN
                  OPINION OF VALUE OR AN OPINION OF VALUE DEVELOPED WITHOUT
                  INVOKING THE DEPARTURE RULE.

             2.   LIMITED APPRAISAL: THE ACT OR PROCESS OF DEVELOPING AN
                  OPINION OF VALUE OR AN OPINION OF VALUED DEVELOPED UNDER
                  AND RESULTING FROM INVOKING THE DEPARTURE RULE.

                                                                              12

             The Complete Appraisal incorporates all of Standard 1 but USPAP
       allows certain departures from Standard 1. When departure is invoked, the
       appraisal becomes a Limited Appraisal. In this particular appraisal, the
       client specifically requested that a Complete Appraisal be prepared;
       thus, departure was not invoked.

             Standard 2 of USPAP allows three categories in REPORTING an
       appraisal or:

                            1. Self-Contained Report
                            2. Summary Report
                            3. Restricted Use Report

       Each appraisal option is dependent upon the level of detail required in
       the report. A comprehensive level of detail is presented in the
       Self-Contained Report; a less detailed, yet concise level of information
       is presented in the Summary Report; and a minimal level of detail is
       presented in the Restricted Use Report. USPAP contains specific
       guidelines which determine what constitutes a Self-Contained, Summary,
       and Restricted Use Report and when use of a particular option is
       appropriate. In this particular assignment, the client requested that a
       Self-Contained Report be prepared. Therefore, a COMPLETE APPRAISAL will
       be developed and presented in a SELF-CONTAINED REPORT.

             The first step in this process involves defining the appraisal
       problem: that is, the identification and appropriate inspection of the
       real estate and properly and accurately identifying the appraisal's
       intended use AND user, purpose(s) or objective(s), effective date(s),
       property rights to be appraised, and the type(s) of value sought.
       Detailed market information pertaining specifically to the subject
       property's value is then collected and analyzed. This information
       includes an applicable market analysis, site and improvement description,
       highest and best use analysis, and the application of the relevant
       valuation techniques used in developing an opinion of the property's
       value(s) including complete assemblage, verification, and analysis of all
       appropriate market data. The final step in the appraisal process is the
       reconciliation or correlation of the values as indicated by the relevant
       valuation techniques.

             The subject property's inspection was conducted only within the
       context of the appraisal process to uncover valuation issues. This
       "appraisal inspection" is NOT to be construed as a building inspection in
       which the intent is to uncover defective building or structural
       components.

<Page>

                                                                              13

       Therefore, this appraisal inspection, as it relates to the property (site
       and improvements), will address only the observed conditions that would
       likely impact the property's valuation issues and/or its overall appeal
       and marketability. Any and all references to the property's inspection
       only infers an "appraisal inspection".

             In this particular appraisal, several of the following sources were
       utilized in providing both general and detailed information pertaining to
       the area real estate market, including sales, listings, rents, general
       market statistics, etc.:

             1.  Office files.
             2.  Federal, state, and local agencies relating to general data and
                 trade associations and private business enterprises relating to
                 the specific property type.
             3.  Market participants including brokers/real estate agents,
                 buyers, sellers, lenders, property managers, landlords, and/or
                 tenants.
             4.  County Register of Deeds' records.
             5.  County and/or City Assessor records.
             6.  Multiple Listing Service records.
             7.  City and/or County Planning and/or Engineering Offices.
             8.  Building Inspector's Office.
             9.  Information provided by the property's owner, manager, and/or
                 any other individuals involved in the property.

             Detailed discussions of each sale, listing, rent, or any other
       appropriate section of the report will provide the informational source,
       when the information was verified, and to whom the information was
       verified. "Office files" is considered the initial (and most favored)
       source of information since this type of information is usually provided
       by individuals having first hand knowledge of a transaction. Often, this
       information was obtained just before, immediately after, or even during
       the progression of a particular transaction. The sources and data used in
       this appraisal are considered reliable. When conflicting information was
       provided, the source deemed most reliable was used. Data believed to be
       unreliable was not included in the report nor used as a basis for the
       value conclusion.

             The following report details the entire appraisal process, starting
       with a proper identification of the subject property and concluding with
       the final market value opinion(s). For ease of use, a simple outline
       format has been used in the following appraisal.

B.     IDENTIFICATION OF THE SUBJECT PROPERTY

       1.    Property Type:

             The primary ownership interest in this particular property involves
             only the subject improvements as they will be located on a leased
             site. Specifically, the completed 40 million gallon ethanol fuel
             plant to be known as "Northern Lights Ethanol" will be located on a
             36.59 acre leased site.

       2.    Address/Location:

             The property's street address of "48416 144th Street, Big Stone
             City, South Dakota" places it about two miles northwest of the
             community's city limits or in an area reflecting predominantly
             agricultural uses.

       3.    Standard Metropolitan Statistical Area (SMSA):   None

       4.    Census Tract #:                                  None

       5.    Legal Description:

             The following legal description was copied from the warranty deed
             in which the current site owner acquired title on April 19, 2001:

                  "PARCEL A IN THE SOUTHWEST QUARTER (SW 1/4) OF SECTION TWELVE
                  (12), TOWNSHIP ONE HUNDRED TWENTY-ONE (121) NORTH, RANGE
                  FORTY-SEVEN (47) WEST OF THE FIFTH PRINCIPAL MERIDIAN, GRANT
                  COUNTY, SOUTH DAKOTA, ACCORDING TO THE RECORDED PLAT THEREOF.

                  PARCEL B IN THE SOUTHEAST QUARTER (SE 1/4) OF SECTION ELEVEN
                  (11), TOWNSHIP ONE HUNDRED TWENTY-ONE (121) NORTH, RANGE
                  FORTY-SEVEN (47) WEST OF THE FIFTH PRINCIPAL MERIDIAN, GRANT
                  COUNTY, SOUTH DAKOTA, ACCORDING TO THE RECORDED PLAT THEREOF."

       6.    Parcel #: Not Yet Assigned

       7.    Ownership History:

             Detailing the subject property's ownership history is a mandatory
             element of a fully documented appraisal that conforms to the
             UNIFORM STANDARDS OF PROFESSIONAL APPRAISAL PRACTICE (USPAP).
             Standards Rule 1-5 of USPAP requires that the appraisal "MUST
             CONSIDER AND ANALYZE ANY PRIOR SALES OF THE PROPERTY BEING
             APPRAISED THAT OCCURRED WITHIN ..." three years for all property
             types except one to four family residential. The intent of this
             requirement is to encourage the research and analysis of prior
             sales of the subject; the time frames cited are minimums. A
             complete title search of the subject property has not been made nor
             is an opinion of title intended to be rendered in the following
             discussion. The Grant County Register of Deeds and Director of Tax
             Equalization offices were referenced to formulate recent ownership
             of the subject property but only for the purposes of this
             appraisal.

             Ownership to the identified subject site was deeded to the current
             owner or Big Stone-Grant Industrial Development and Transportation,
             L.L.C. on April 19, 2001, from Ottertail Corporation,
             Montana-Dakota Utilities Company, and Northwestern Public Service.
             (Deed is filed in Book 108, page 161.) Big Stone-Grant Industrial
             Development and Transportation, L.L.C. is a subsidiary of the
             sellers who own the adjacent Big Stone power

                                                                              15

             plant. A search of the Register of Deeds records indicate that the
             related ownership dates back to at least 1986. Thus, the site has
             been part of the Big Stone power plant ownership for well in excess
             of three years preceding the appraisal's effective date. A separate
             ownership group and the subsequent deeding of the identified
             subject parcel to Big Stone-Grant Industrial Development and
             Transportation, L.L.C. was required to establish the lease with the
             owner/borrower. (The "Big Stone Plant Property Lease" will be
             further detailed in the following report.) Based on the preceding,
             the land or site is and will continue to be owned by Big
             Stone-Grant Industrial Development and Transportation, L.L.C. with
             the owner/borrower or Northern Lights Ethanol, LLC securing use of
             the identified subject site through a 99 year lease.

C.     DEFINITION OF THE APPRAISAL PROBLEM

       1.    Appraisal's Intended Use and User:

             This appraisal was made at the request of Mr. Robert J. Edstrom,
             Real Estate Technical Services, representing the client or U.S.
             Bank National Association. Per the engagement letter, the
             "APPRAISAL WILL BE USED AS THE BASIS FOR LOAN UNDERWRITING". This
             report is intended for use only by U.S. Bank National Association
             and/or its assigns; use of this report by others is NOT intended.

       2.    Appraisal Objective(s), Property Rights Appraised, and Effective
             Date(s):

             The engagement letter indicates that "THE PURPOSE OF THE APPRAISAL
             IS TO PROVIDE A SUPPORTED OPINION OF THE MARKET VALUE OF THE REAL
             ESTATE AS OF THE DATE OF YOUR INSPECTION, IN ACCORDANCE WITH THE
             APPRAISAL POLICIES AND PROCEDURES OF U.S. BANCORP, AND AS DEFINED
             BY 12 C.F.R. 34. THE FOLLOWING VALUE(S) ARE REQUESTED:

                          LEASEHOLD MARKET VALUE AS IS
             LEASEHOLD MARKET VALUE UPON COMPLETION OF CONSTRUCTION

             The client specified appraisal objectives require that an opinion
             of market value be provided. MARKET VALUE, is defined on pages 5
             and 6 of the client's "Commercial Appraisal Reporting Guidelines"
             as:

                  "THE MOST PROBABLE PRICE WHICH A PROPERTY SHOULD BRING IN A
                  COMPETITIVE AND OPEN MARKET UNDER ALL CONDITIONS REQUISITE TO
                  A FAIR SALE, 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 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 BEST INTERESTS;

                  (3)  A REASONABLE 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 BY ANYONE ASSOCIATED WITH
                       THE SALE."

             The client also specified that "leasehold" real property interests
             be addressed. According to THE APPRAISAL OF REAL ESTATE, 12th
             Edition, page 8, published by the Appraisal Institute, REAL
             PROPERTY INTERESTS are described as follows:

                  "REAL PROPERTY INCLUDES ALL INTERESTS, BENEFITS, AND RIGHTS
                  INHERENT IN THE OWNERSHIP OF PHYSICAL REAL ESTATE. A RIGHT OR
                  INTEREST IN REAL ESTATE IS ALSO REFERRED TO AS AN ESTATE.
                  SPECIFICALLY, AN ESTATE IN LAND IS THE DEGREE, NATURE, OR
                  EXTENT OF INTEREST THAT A PERSON HAS IN IT.

                  THE TOTAL RANGE OF OWNERSHIP INTERESTS IN REAL PROPERTY
                  IS CALLED THE BUNDLE OF RIGHTS. IMAGINE A BUNDLE OF
                  STICKS WHERE EACH 'STICK' REPRESENTS A DISTINCT AND
                  SEPARATE RIGHT OR INTEREST. THE BUNDLE OF RIGHTS
                  CONTAINS ALL THE INTERESTS

<Page>

                                                                              17

                  IN REAL PROPERTY, INCLUDING THE RIGHT TO USE THE REAL ESTATE,
                  SELL IT, LEASE IT, ENTER IT, AND GIVE IT AWAY, AND EACH
                  'STICK' CAN BE SEPARATED FROM THE BUNDLE AND TRADED IN THE
                  MARKET."

             It is possible to own all or only some of the rights in a parcel of
             real estate. The extent of ownership determines the kind of
             interest, or estate, that is held. A person who owns all the
             property rights is said to have "FEE SIMPLE TITLE" or estate
             defined as:

                  "ABSOLUTE OWNERSHIP UNENCUMBERED BY ANY OTHER INTEREST
                  OR ESTATE, SUBJECT ONLY TO THE LIMITATIONS IMPOSED BY
                  THE GOVERNMENTAL POWERS OF TAXATION, EMINENT DOMAIN,
                  POLICE POWER, AND ESCHEAT."
                  (Appraisal Institute, DICTIONARY OF REAL ESTATE
                  APPRAISAL, 3RD EDITION; 140)

             Fee simple ownership, often referred to as ABSOLUTE, implies that
             the subject property would be free of encumbrances or restrictions
             which could affect ownership or title. In this particular property,
             "fee simple" ownership will not exist as the completed improvements
             will be located on a site leased from the property owner or Big
             Stone-Grant Industrial Development and Transportation, L.L.C.
             Therefore, the tenant or improvement owner/borrower or Northern
             Lights Ethanol, LLC cannot provide fee simple ownership in the
             completed improvements. Only a "LEASEHOLD INTEREST" will exist; it
             is defined as:

                  "THE INTEREST HELD BY THE LESSEE (THE TENANT OR RENTER)
                  THROUGH A LEASE CONVEYING THE RIGHTS OF USE AND
                  OCCUPANCY FOR A STATED TERM UNDER CERTAIN CONDITIONS."
                  (Appraisal Institute, DICTIONARY OF REAL ESTATE
                  APPRAISAL, 3RD EDITION; 204)

             Leasehold interest ownership implies that, when a lease is
             transmitted, a tenant (in this case, the tenant being the
             owner/borrower or Northern Lights Ethanol, LLC) usually acquires
             the rights to possess the property for the lease period, to
             sublease the property if desired, and occasionally improve the
             property under the restrictions specified in the lease. In return,
             the tenant is obligated to pay rent, surrender possession of the
             property at the termination of the lease, remove any improvements
             the lessee has modified or constructed if specified, and abide by
             the lease provisions. Thus, fee simple title to the as-complete
             improved subject property (site and improvements) will not be
             available. The valuation analysis of the subject improvements will,
             therefore, consider the impact the site lease has on the fee simple
             market value by estimating the individual leased fee and leasehold
             interests.

             The first specified appraisal objective alludes to developing an
             opinion of the leasehold market value of the subject property based
             on its "as-is" condition. VALUE AS-IS, as used in the following
             report, is defined as:

                  "THE VALUE OF SPECIFIC OWNERSHIP RIGHTS TO AN IDENTIFIED
                  PARCEL OF REAL ESTATE AS OF THE EFFECTIVE DATE OF THE
                  APPRAISAL; RELATES TO WHAT PHYSICALLY EXISTS AND IS LEGALLY
                  PERMISSIBLE AND EXCLUDES ALL ASSUMPTIONS CONCERNING
                  HYPOTHETICAL MARKET CONDITIONS OR POSSIBLE REZONING."
                  (Appraisal Institute, THE DICTIONARY OF REAL ESTATE APPRAISAL,
                  3RD EDITION; p. 385)

             As of the inspection date or September 17, 2001, the identified
             leased site was partially improved; the construction manager or Mr.
             Kurt Mahon estimated that the improvements were about 25% complete.
             Again, this site is leased and, as the following analysis of the
             leasehold interest will demonstrate, the lease terms and/or the
             site's contributory value are insignificant when compared to the
             property's overall value. For this reason, no marketable interest
             in the lease has been created. Even so, the owner/borrower would
             not have a marketable interest in the underlying site as of the
             inspection date. The only marketable interest would be in the
             partially complete improvements. Thus, one appraisal objective is

<Page>

                                                                              18

             to develop an opinion of the partially built improvements or as-is
             leasehold market value as of September 17, 2001, or the appraisal
             inspection date.

             The other appraisal objective is to provide an opinion of the
             completed subject improvement's leasehold market value as of a
             future or prospective date as completion is not scheduled until
             November 1, 2002, as indicated by the owner/borrower's
             representative or Mr. Larry Ward. Therefore, this objective's
             effective date of valuation would be November 1, 2002. It must also
             be assumed that the proposed project is completed in a workmanlike
             manner according to the plans and specifications provided by the
             owner/borrower and detailed throughout the following appraisal
             report. Any significant deviation from the plans and specifications
             could render the appraisal and its results void.

             Developing an opinion of the subject improvement's leasehold market
             value based on this significant assumption or assuming that the
             project is complete is deemed an "extraordinary assumption" or by
             USPAP definition: "AN ASSUMPTION, DIRECTLY RELATED TO A SPECIFIC
             ASSIGNMENT, WHICH, IF FOUND TO BE FALSE, COULD ALTER THE
             APPRAISER'S OPINIONS OR CONCLUSIONS." For the purpose of this
             analysis, it will be assumed that market conditions relating to
             this particular property type or that of a retail facility would
             remain unchanged through the prospective date. This extraordinary
             assumption is clearly required for purposes of reasonable analysis
             within the appraisal's objective and intended use. Use of this
             extraordinary assumption still results in a credible analysis.

             This particular property type or that of an operating ethanol
             plant, which is anticipated to be a profitable business venture,
             incorporates something more than simply real estate. Specifically,
             a considerable amount of non-real property items are included such
             as furniture, fixtures, and equipment but, more importantly, other
             intangible items are integral components such as marketing and
             management skills, an assembled work force, working capital, or all
             other items needed to create a profitable ethanol plant. In
             essence, the operation and/or purchase of an operating ethanol
             plant would include the GOING-CONCERN VALUE, defined as:

                  "THE VALUE CREATED BY A PROVEN PROPERTY OPERATION;
                  CONSIDERED AS A SEPARATE ENTITY TO BE VALUED WITH A
                  SPECIFIC BUSINESS ESTABLISHMENT."
                  (Appraisal Institute, DICTIONARY OF REAL ESTATE APPRAISAL,
                  THIRD EDITION; 160)

             A profitable ethanol plant, a characteristic that is anticipated in
             the completed subject property's operation, is normally purchased
             with this going concern value concept incorporated within the
             transaction. For this reason, the following appraisal report will
             develop the subject property's "going concern" values. (All
             references to value in the following appraisal report will include
             the going concern concept.) Based on the preceding, the primary
             appraisal objective needs to include the going concern value
             concept.

             Based on the preceding discussion, this appraisal has a twofold
             objective or developing an opinion of the:

               1. As-complete subject improvement's prospective leasehold going
                  concern market value as of November 1, 2002, or the date the
                  improvements are scheduled for completion.

               2. Partially built improvement's as-is leasehold market value as
                  of September 17, 2001, or the appraisal inspection date.

             It must be emphasized that the enclosed written appraisal report
             was completed on November 9, 2001. No evidence exists to suggest
             that market conditions will change measurably between the initial
             appraisal inspection or September 17, 2001, the

<Page>

                                                                              19

             completion date of the written appraisal report or November 9,
             2001, and the prospective valuation date of November 1, 2002.

             The most appropriate appraisal process used in developing an
             opinion of the improvement owner's leasehold market value is to (1)
             first develop an opinion of the subject property's (site and
             improvements) market value assuming fee simple ownership existed
             and then (2) focus on the valuation of Northern Lights Ethanol,
             LLC's or the site tenant's leasehold interest in the improvements.
             This appraisal report will start with first developing an opinion
             of the subject property's fee simple market value which, again,
             would include both the site and improvements. The development of an
             opinion of the subject improvement's as-complete and as-is
             leasehold market values will then follow.

       3.    Special Instructions and Other Conditions:

             The appraisal was made to conform to the Appraisal Institute's Code
             of Professional Ethics and Standards of Professional Appraisal
             Practice and the most recent edition of the UNIFORM STANDARDS OF
             PROFESSIONAL APPRAISAL PRACTICE (USPAP), adopted by the Appraisal
             Standards Board of the Appraisal Foundation, and should meet the
             minimum requirements for all federally-related transactions.
             Additionally, the appraisal was made in conformance with the Office
             of the Comptroller of Currency (OCC)-12CFR 34, Subpart C and/or 12
             CFR 7.3025; Federal Deposit Insurance Corporation (FDIC)-12 CFR
             323; Title XI of Financial Institutions Reform, Recovery, and

D.     STATEMENT OF COMPETENCY

             The competency provision of the UNIFORM STANDARDS OF PROFESSIONAL
       APPRAISAL PRACTICE (USPAP) recognizes that the background and experience
       of appraisers can vary widely, and that a lack of knowledge or experience
       can lead to inaccurate or inappropriate appraisal practice. The
       Competency Provision states:

             PRIOR TO ACCEPTING AN ASSIGNMENT OR ENTERING INTO AN AGREEMENT TO
             PERFORM ANY ASSIGNMENT, AN APPRAISER MUST PROPERLY IDENTIFY THE
             PROBLEM TO BE ADDRESSED AND HAVE THE KNOWLEDGE AND EXPERIENCE TO
             COMPLETE THE ASSIGNMENT COMPETENTLY; OR ALTERNATIVELY:

             1.   DISCLOSE THE LACK OF KNOWLEDGE AND/OR EXPERIENCE TO THE CLIENT
                  BEFORE ACCEPTING THE ASSIGNMENT; AND
             2.   TAKE ALL STEPS NECESSARY OR APPROPRIATE TO COMPLETE THE
                  ASSIGNMENT COMPETENTLY; AND
             3.   DESCRIBE THE LACK OF KNOWLEDGE AND/OR EXPERIENCE AND THE STEPS
                  TAKEN TO COMPLETE THE ASSIGNMENT COMPETENTLY IN THE REPORT."

             This appraisal assignment was accepted by Dakota Appraisal &
       Consulting, Ltd., from the client or U.S. Bank National Association, as
       represented by Mr. Robert J. Edstrom, Real Estate Technical Services for
       U.S. Bank National Association. Prior to receiving the assignment, the
       client requested that an appraisal proposal be submitted. Evidently, the
       client was of the opinion that the undersigned had the competency to
       undertake the assignment as it was awarded. The undersigned has not
       completed prior appraisals on an ethanol plant. However, appraisals on
       other types of processing plants have been completed within the recent
       past. More specific to this project, the undersigned met personally with
       the owner/borrower's representative or Mr. Larry Ward of Broin &
       Associates, Inc. Broin & Associates are deemed one of the country's
       largest ethanol plant developers involved in plant design, engineering,
       construction, and operation. Additionally, contacts were made to various
       sources within the industry relative to present and future markets,
       pricing, supply and demand factors, etc. Many major industry publications
       and sources will be referenced in the following report.

             Additionally, the knowledge and experience of the signatory of this
       appraisal in the valuation of somewhat related properties is well
       established, is confirmed through the successful completion of numerous
       appraisals and educational courses offered by the Appraisal Institute,
       and the signatory appraiser is board-certified through the North Dakota
       Real Estate Appraiser Qualifications and Ethics Board (NDCG-1009) and the
       South Dakota Department of Commerce and Regulation (Certificate
       #324CG-2001R). Lastly, every effort has been made to secure the
       information, knowledge, and applicable data needed to complete this
       assignment. Based on the preceding, it is the opinion of the signatory of
       this appraisal that all necessary and appropriate steps were taken to
       insure that a properly developed appraisal has been made.

E.     MARKET AREA ANALYSIS

       DEFINED --

             Value of real property is dependent upon the recognition and
       understanding of the area market economic trends. Particular trends may
       vary with the appraisal problem and the type of real estate appraised,
       but a probable direction, extent, and impact of economic change must be
       reasonably identified and forecasted to measure their probable impact on
       the property being appraised. Thus, the conditions and potential of the
       local economy, and, possibly, national and regional economics, are
       relevant to most appraisal assignments.

       STATE ECONOMICS--

             The subject property is located in the Grant County, South Dakota,
       area market. South Dakota is still generally considered an agricultural
       state in terms of percentage of land use. However, the percentage of all
       income earned in the state that relates to agriculture has declined in
       recent years since the State is attempting to gradually diversify its
       economic base with increased emphasis generated from non-farm activity.
       South Dakota has been successful in attracting comparatively more
       businesses when compared to most other area states as it offers no
       corporate income tax, no personal income tax, no business inventory tax,
       no personal property tax, and competitive premiums for workers and
       unemployment compensation insurance premiums. With the diversification of
       the economic base, most indicators are revealing a mostly stable economy.

             South Dakota's population increased from 690,768 in 1980 to 696,004
       in 1990 and to 754,844 in 2000 or an increase of 64,087 people or 9.3% or
       about .5% per year over the last 20 years. However, if the increase in
       only Sioux Falls' (states largest city) population of 42,632 people were
       deducted from the state's population increase, the state's overall
       population statistics would show only a modest increase.

       LOCATION AND TRANSPORTATION --

             The completed subject property will be located about two miles
       northwest of the Big Stone City, South Dakota, city limits. As such, it
       will be located in the extreme northeast corner of Grant County; Grant
       County is located in the northeast quadrant of South Dakota. The
       "L-shaped"

<Page>

                                                                              22

       shaped" Grant County has the Minnesota-South Dakota state line as its
       east boundary and its north boundary is located only about 42 miles south
       of the South Dakota-North Dakota state line. The county's extreme
       northwest corner extends about eight miles west of Interstate 29. By far,
       the predominant land use within Grant County and the entire region or
       extending throughout northeast South Dakota, southeast North Dakota, and
       west central Minnesota is for agricultural or farming purposes.

             The predominant mode of area transportation is via the highway
       system. Interstate 29 is the major north-south traffic arterial serving
       the extreme east end of North and South Dakota. The major east-west
       traffic arterial through Grant County is U.S Highway 12. It enters the
       county on the extreme northeast corner or at Big Stone City and exits
       near the county's northwest corner at its intersection with Highway 81. A
       series of state highways also transverse the county with the most
       significant being north-south State Highway 15 through the county's
       central part.

             Other area county transportation facilities include the Burlington
       Northern/Santa Fe (BNSF) Railroad that, for the most part, parallels U.S.
       Highway 12 through the county and the Sisseton-Milbank (SM) Railroad. The
       SM Railroad is simply a 38 mile track extending from Milbank on the south
       to Sisseton, South Dakota, to the northwest. By far, the BNSF Railroad is
       the predominant county rail transportation. (Availability of rail is a
       significant characteristic in site selection for an ethanol plant.) Other
       area transportation modes include a small airport at Milbank, South
       Dakota, and area trucking firms. Collectively, comparatively good modes
       of transportation exist within Grant County, especially as it relates to
       the availability and proximity to rail and the interstate system.

       COUNTY SUMMARY --

             As earlier detailed, South Dakota is primarily an agricultural
       state in terms of land use and Grant County is no exception. The county's
       primary economic base is heavily dependent upon the agricultural
       industry. About 70% of the county land is used as cropland with the
       balance used as pasture or hayland. According to the latest or 1997 Ag
       Census, Grant County had 359,043 acres in farmland with 534 farms;
       average farm size was 672 acres. Crop production is the primary source of
       income derived primarily from the production of corn, spring

<Page>

                                                                              23

       wheat, and soybeans. However, Grant County has been the state's leading
       dairy producer over the last five years (see enclosed agricultural
       ratings). According to the latest industry figures or those for 1998,
       farm employment was the county's third largest employer at 681 employees
       behind services at 1,247 employees and retail at 830 employees.

             The one commodity that has significant importance in the subject's
       plant is that of corn. The state's corn production has increased
       significantly over the last three decades. Specifically, state-wide corn
       production approximated about 100 to 150 million bushels in the mid 1970s
       but has increased to approximately 400 million bushels in the last three
       years with 1999 and 2000 having total production approximating 425
       million bushels. The vast majority of the corn is grown in the eastern
       one-third of the state or in the vicinity of Grant County. As the
       enclosed statistics indicate, Grant County generates about 1.75% of the
       total statewide corn production; Grant County's corn production has
       averaged nearly 7.2 million bushels over the last five years.

             The Grant County seat or Milbank had a 2000 population of 3,640
       which represented 46.4% of the total county population of 7,847. Grant
       County, Milbank, and the closest community or Big Stone City have all had
       significant population declines over the last four decades. Specifically,
       Grant County's population peaked in 1960 at 9,913 people but declined to
       7,847 in 2000 or a total decline of nearly 21%. Milbank's population
       peaked in 1980 at 4,120 but has since declined to 3,640 or a decline of
       11.7%. Lastly, Big Stone City's population peaked at 718 in 1960 but
       declined to 605 in 2000 or a decline of nearly 16%. These population
       declines are consistent for most rural located statewide counties and are
       almost directly attributable to the demise of the agricultural industry.

             The economy of the closest community or Big Stone City relies
       almost entirely on two industries or agriculture and utilities. The Big
       Stone Power Plant, located only about two miles to the northwest of Big
       Stone City is the area's largest non-farm employer; it employs about 76
       people. The area is also known as one of the three leading granite mining
       areas in the United States. Big Stone City offers only limited retail
       services as most are provided in Milbank, located only eleven miles
       southwest of Big Stone City. Only one single family permit per year has
       been issued in Big Stone City since 1993. Milbank is the county's primary
       service center as it offers

                                                                              24

       the county's largest school district, a 35 bed hospital, considerable
       long-term care/assisted living facilities, and a majority of the non-ag
       employment. Single family residential building permits have averaged
       6.6/year from 1993 through 1999. County-wide, a favorable unemployment
       rate exists at about 4% or less.

       AGRICULTURAL ECONOMY --

             The area's agricultural economy is in a constant state of
       uncertainty as comparatively low commodity prices have been received in
       recent years, production costs seem to be ever-increasing, and the simple
       reliance upon Mother Nature creates considerable uncertainty in probable
       profitability. The adjacent exhibit details that the average price per
       acre of statewide farmland has increased every year since the last major
       drought or in the late 1980's. However, farming's profitability has
       resulted from the creation of larger farms, increased yields, and
       increased government subsidies. In turn, the number of farms has
       decreased measurably over the last several decades. The outlook for
       continued increases in farmland values is favorable but, if present, such
       increases tend to reflect a gradual rate of growth perceptible only over
       a long period measured in years. It should also be acknowledged that,
       while the agricultural economy continues to improve, the memory of recent
       depressed conditions would, in all likelihood, continue to shape the
       actions of buyers to some extent in terms of cautious attitudes.

             Most area community leaders and local county and city governments
       have become more proactive in terms of attracting employment beyond the
       agricultural industry. In recent years, value added agricultural
       industries have received considerable interest. Ethanol plant development
       has recently emerged as the most significant value added industry for
       high corn crop production areas. More specific to this region, the 40
       million gallon Dakota Ethanol plant opened on August 1, 2001, in
       Wentworth, South Dakota (a community located about 100 miles south on
       Interstate 29, just outside Madison, South Dakota), and groundbreaking
       for a 40 million gallon ethanol plant, known as Glacial Lakes Corn
       Processors, took place in Watertown, South Dakota (a community located
       about 50 miles southwest), on August 7, 2001. Also, the $260 million
       ProGold corn processing plant (designed to produce corn syrup sweetener)

       North Dakota. (Plant was originally member operated but it has been since
       leased to Cargill.) Wahpeton, North Dakota, is located about 75 miles
       north of the subject.

             Generally, most agricultural value added processing facilities have
       been generally profitable as adequate labor exists, financial incentives
       are readily available, and the area is well known as a major producer of
       raw agricultural products. Specifically, the eastern border of North and
       South Dakota and the western border of Minnesota has some of the most
       productive agricultural farmland in the entire region. As a result, the
       region produces some of the country's highest yields.

       SUMMARY --

             The state's and Grant County's predominant economic base is still
       that of agriculture or an economic base still being viewed as being quite
       static. Any renewal of optimism in the area's overall agricultural real
       estate market is tempered by the still comparatively low commodity prices
       and increased costs of operation. Continued stability appears to be the
       most reasonable anticipation for the area's agricultural real estate
       market. Diversification through value added products within the
       agricultural industry is now perceived by many as an avenue to increase
       farming's profitability. The more local market definitely has the
       potential to provide a continued supply of raw product which, in this
       particular property type, would be corn.

F.     NEIGHBORHOOD ANALYSIS

       DEFINED  --

             A NEIGHBORHOOD is defined as:

             "A GROUP OF COMPLEMENTARY LAND USES; A CONGRUOUS GROUPING OF
             INHABITANTS, BUILDINGS, OR BUSINESS ENTERPRISES."
             (Appraisal Institute, THE DICTIONARY OF REAL ESTATE APPRAISAL,
             THIRD EDITION: 242)

       The Neighborhood Analysis provides information in reference to the
       neighborhood's history, type of development, present land use, and
       present and future potential. Relating the subject's location to the
       neighborhood provides an understanding of how the subject will conform to
       the neighborhood use and neighborhood market.

       BOUNDARY DESCRIPTION --

             The subject property's neighborhood boundaries are somewhat
       nondescript as it is/will be located in a predominantly agricultural use
       area in Grant County's extreme northeast corner. The east border of South
       Dakota is a logical neighborhood boundary but, as would be the case in
       all other perimeter boundaries, similar land use and similar economics
       extend throughout the region. Therefore, no specified neighborhood
       boundaries exist.

       ACCESSIBILITY --

             The same transportation arterials that serve the entire market
       area, as previously defined, would also serve this specific location. The
       two major highways serving Big Stone City are U.S. Highways 12 and 75;
       they intersect just on the east side of the state boundary at Ortonville,
       Minnesota. Also, the BNSF Railroad passes through Big Stone City. Even
       the community's proximity to Interstate 29 or approximately 32 miles west
       via Highway 12 is deemed a favorable access characteristic.

       LAND DEVELOPMENT/USES--

             Again, the completed subject property will be located about two
       miles northwest of Big Stone City. The predominant land use outside the
       city limits is that of agricultural farmland with the exception of
       scattered rural residences and scattered commercial/industrial single
       land users. The most significant commercial/industrial land user in the
       area is the Big Stone Power Plant. This 450 megawatt power plant opened
       in 1975 and currently employs 76. According to "Tom" at Big Stone Power,
       the plant is currently undertaking a feasibility study to determine
       whether the plant should

<Page>

                                                                              27

       expand by an additional 600 megawatts, due primarily to the recent energy
       concerns. The only other noted commercial or industrial users in
       proximity to Big Stone City or even Milbank include some scattered
       warehouses, some commercial users along the area highways, gravel pits, a
       concrete processing plant, and area granite mines. A good maintenance
       level was observed in area improved properties with owner occupancy being
       predominant.

       TRENDS --

             The current predominant land use or agricultural farmland will
       continue as the predominant land use into the foreseeable future. Simply,
       the rural nature of the area precludes any significant commercial or
       industrial development beyond periodic single use projects. As in the
       broader agricultural market, agricultural values within this more
       immediate area will tend to remain stable or increase modestly unless
       agricultural commodity prices increase significantly.

       SUMMARY --

             The overall appeal and marketability of the completed subject
       property will not be significantly impacted by the defined neighborhood.
       Rather, its overall appeal, marketability, and, ultimately, its
       profitability is more impacted by the regional nature of the agricultural
       economy. Even so, the local or more immediate area provides those
       services needed to support the proposed use. Also, this proposed use is
       consistent with the existing neighborhood land use.

G.     SITE DESCRIPTION

       1.    Introduction:

             As paraphrased from page 189 of The Appraisal of Real Estate (12th
             Edition, published by the Appraisal Institute), a land or site
             description is a detailed listing of factual data and information
             on pertinent physical characteristics. A land or site analysis is a
             careful study of the site's factual data in relation to the
             neighborhood characteristics that create, enhance, or detract from
             the utility and marketability of the land or site as compared with
             competing comparable land, sites, or alternate locations. Even
             though a site is described as though vacant, most land parcels have
             been improved to some extent so the term site is used in the
             following description.

             The primary appraisal objective is to develop an opinion of the
             subject improvement's market value as they will be located on a
             leased site. Thus, the site is not part of this ownership interest
             other than a leasehold interest may exist if the contractual land
             rent is far below market rent. (This discussion will be detailed in
             the following report.) Even though a site is not part of the
             ownership interest to be addressed, a description of the site upon
             which the improvements will be located and function is both useful
             and necessary as it provides for a more complete understanding of
             the entire property.

             The subject site involves two separate and distinct parcels or
             Parcel A in the SW 1/4 of Section 12 and Parcel B in the SE 1/4 of
             Section 11, both located in Township 121 North, Range 47 West,
             Grant County, South Dakota. However, only Parcel A will be improved
             with the proposed ethanol plant. Parcel B is located west of Parcel
             A, west and adjacent to 484th Avenue or the north-south street
             between Parcel A on the east and Parcel B on the west. Essentially,
             Parcel B was included as some borrow or fill was needed from this
             parcel to improve Parcel A. Parcel B's limited utility and the lack
             of market precludes it having a separate and distinct use. For this
             reason, it will be simply carried as surplus land or additional
             land that allows for future expansion of the existing improvements.

       2.    Location and Adjacent Site Users:

             Parcel A's street address of "48416 144th Street, Big Stone City,
             South Dakota" places it about two miles northwest of the city
             limits. Specifically, the site is located on the northeast corner
             of 144th Street on the south and 484th Avenue on the west. Parcel B
             is located west and adjacent but across the street (484th Avenue)
             to the west. Adjacent land users include the Big Stone Power Plant
             to the north and agricultural farmland in all other directions.

       3.    Physical Characteristics (Shape, Size, Topography, Etc.):

             a.   Parcel A: This triangular shaped site has 1,625.4 feet of
                  width along the south and its depth along the west boundary is
                  1,519 feet. The plat map details Parcel A's size at 29.56
                  acres but it includes 1.26 acres of right-of-way. This road
                  right-of-way cannot be used as part of the area to be
                  developed. Thus, Parcel A's net acreage is 28.30 acres (29.56
                  acres less 1.26 acres right-of-way). The size is significant
                  for an industrial or commercial user but it is measurably
                  smaller if compared to area farmland parcels. Prior to
                  development of its current use, the parcel was used as
                  farmland.

                  The site has a moderate slope from north to south but site
                  preparation for the existing use will provide for adequate
                  drainage. It can only be assumed that soil tests were
                  conducted for development of the site for the proposed use.
                  These soil tests were not provided. For this reason, it can
                  only be assumed that the soils are

<Page>

                                                                              29

                  sufficient to support development. No obvious limiting
                  physical characteristics were apparent.

             b.   Parcel B: This triangular shaped parcel has 897.3 feet of
                  frontage along its east boundary or along 484th Avenue. It
                  then extends approximately 770 feet west at a point where the
                  triangle connects. The plat indicates a total site size of
                  8.29 acres. The site was used as agricultural farmland but a
                  portion has since been excavated for fill needed to improve
                  Parcel A. It has a rolling topography.

       4.    Access and Visibility:

             Good access is provided to both parcels by the two adjacent
             streets. Both roadways are asphalt surfaced but it became apparent
             that both will need to be upgraded and/or resurfaced to accommodate
             the heavy truck traffic that will service the sites. Parcel A will
             also be accessed by a 100 foot wide railroad spur line that will
             connect through the subject site's southeast corner to the spur
             line off the BNSF main track. This spur line currently connects to
             the Big Stone Power Plant. The availability of rail was a
             significant factor in selecting this site by the current user. Good
             site visibility also exists as the sites afford considerable street
             frontage and the adjacent land users do not prohibit line of sight.

       5.    Flood Plain Status, Easements, Environmental Concerns, and Other
             Encumbrances:

             The enclosed flood map details that only those county areas
             designated "Zone A" are located within a special flood hazard area.
             The subject site is not located within a Zone A area and,
             therefore, is NOT within an identified flood hazard area. Thus,
             flood insurance should not be a required contingency to obtaining
             lender financing. No evidence was provided to indicate that the
             sites are adversely encumbered with easements. It can only be
             assumed that all municipal and public services are provided off the
             adjacent streets. No apparent adverse encumbrances or encroachments
             were evident.

             A "Phase I Environmental Property Evaluation" was completed on the
             subject sites by American Technical Services , Inc. (ATS) of Sioux
             Falls, South Dakota, dated May 2, 2001. Page 9 of the report states
             that "THE ASSESSMENT HAS REVEALED NO EVIDENCE OF RECOGNIZED
             ENVIRONMENTAL CONDITIONS IN CONNECTION WITH THE PROPERTY. BASED ON
             THE EVALUATION OF COLLECTED SUBSURFACE DATA, ATS DOES NOT RECOMMEND
             FURTHER SITE ASSESSMENT ACTIVITIES." Based on this report, it will
             be assumed that no environmental concerns exist within the subject
             site.

       6.    Off-site Improvements:

             Both adjacent streets are standard two lane asphalt surfaced county
             roads that will undoubtedly need to be reconstructed/resurfaced in
             the near future. No other street improvements exist. The site
             is/will be serviced by city water and sewer. The community of Big
             Stone in conjunction with the county will be providing these
             municipal services to the site. Electricity is being provided by
             the adjacent Big Stone Power Plant. The availability of adequate
             electrical power, water, and sewer are significant components in
             development of this site.

       7.    Zoning:

             The subject site is zoned "CI-Commercial/Industrial District".
             According to Section 1102 of the Grant County Comprehensive Zoning
             regulations, this district "IS INTENDED FOR COMMERCIAL AND
             INDUSTRIAL USES WHICH DUE TO THEIR SIZE AND NATURE REQUIRE HIGHWAY
             ACCESS." The only permitted uses are those allowed in the
             agricultural zoning district with the exception of residential
             dwellings. All other uses require a conditional use permit.

<Page>

                                                                              30

             However, a significant number of condition uses are allowed. The
             required lot area is determined by "NEED, SETBACK, SIDE YARDS, ...
             HOWEVER, IN NO CASE SHALL A LOT HAVE LESS THAN TWO (2) ACRES."
             Other yard requirements exist. A copy of the CI zoning district
             regulation is enclosed in the Addenda. (No zoning map was available
             from the county officials.)

       8.    Summary:

             Again, the "subject site" involves both Parcels A and B totaling
             36.59 acres. The sites will be developed with or have availability
             to all municipal services, will feature a corner location adjacent
             to two asphalt surfaced roadways, and have railroad accessibility.
             Thus, the site is deemed to have reasonably good characteristics as
             it relates to a rural located industrial site.

       9.    Subject Site's Representative Photographs:

             The following pictures depict primarily the partially improved
             Parcel A. Parcel B can be viewed from various street scenes. These
             pictures, taken on September 17, 2001, attempt to depict the site's
             overall characteristics and vicinity/street scenes.

H.     DESCRIPTION OF IMPROVEMENTS:

       1.    Introduction:

             The completed subject improvements or that of a 40 million gallon
             ethanol fuel plant will involve extensive building components and
             considerable specialized fixtures and equipment. Therefore, this
             description is intended to familiarize the reader with the general
             construction, finish, and utility of the improvements AND needed
             equipment and fixtures assuming the plant were complete. An
             operating ethanol plant will require the use of considerable
             non-real property items to include all the furniture, fixtures, and
             equipment (FF&E). (For ease of reference, the following appraisal
             will simply reference all FF&E simply as "equipment".) Much of the
             equipment is considered personal property in that it is not
             permanently affixed to the buildings but other equipment such as
             the conveyors, scales, boilers, etc. are normally fixtures or
             equipment permanently affixed to the real estate; they normally
             become part of the real estate.

             The following briefly describes the proposed subject improvements
             and equipment/fixtures based on the (a) owner/borrower provided
             plans and specifications, (b) an on-site inspection by the
             undersigned of a now operating, almost identical ethanol plant
             known as Dakota Ethanol plant located in Wentworth, South Dakota,
             on September 18, 2001, and (c) considerable input provided by the
             developer or Mr. Larry Ward of Broin & Associates, Inc. The
             undersigned personally met with Mr. Ward on September 18, 2001, and
             had numerous phone conversations over the course of completing this
             assignment. The building plans were drawn by Short, Elliot,
             Hendrickson Inc. (SEH) of St. Cloud, MN, and are referenced as File
             No. ABROIN0201.00, dated October 3, 2001. The millwright and
             mechanical package plans were provided by Broin & Associates of
             Sioux Falls, South Dakota, and are referenced as Project NLE, dated
             July 16, 2001. Both firms have been actively involved in the design
             and/or construction of similar ethanol plants throughout the
             region, the most recent being the aforementioned Dakota Ethanol
             plant located in Wentworth, South Dakota. (This plant opened on
             August 1, 2001.) It will be assumed that the proposed improvements
             will be completed per these plans and specifications. Any
             significant deviation from this information could render the
             appraisal and its results void. No attempt was made to detail all
             improvement or equipment characteristics but it should be
             sufficient as to provide a basic overview.

       2.    Environmental and the Americans with Disabilities Act (ADA)
             Concerns:

             The completed subject improvements will be new and, for this
             reason, the building components and the furniture, fixtures, and
             equipment (FF&E) should not contain hazardous materials. The
             Americans with Disabilities Act (ADA) became effective January 26,
             1992, or a date preceding the subject improvement's estimated
             completion date of November 1, 2002. Therefore, it can only be
             assumed that the proposed improvements will be constructed in
             compliance with the ADA requirements.

       3.    History:

             The building permit to construct the improvements was issued on
             April 18, 2001. Site preparation started in mid-May with the first
             concrete poured on June 7, 2001. As of the inspection date or
             September 17, 2001, about 25% of the construction had been
             complete. Completion is scheduled for November 1, 2002. This
             completion date is deemed reasonable, assuming no undue delays
             arising from inclement weather or other unknown factors.

       4.    Site Utilization-Parcel A Only:

             a.   Site Access: Two driveways off 144th Street on the south will
                  be provided. The one located near the site's southeast corner
                  will provide the primary truck access as it leads to the scale
                  house, truck scale, and eventually to the grain receiving
                  area. The second access along 144th Street will be located
                  near the site's approximate center providing access to the
                  parking lot for the administrative office building. No access
                  points are detailed along 484th Avenue. Rail access will also
                  be provided along the site's northeast side from an existing
                  spur line serving the adjacent Big Stone Power Plant. Good
                  site access will be afforded.

             b.   Building Placement: Most areas of Parcel A will be improved
                  with various building or equipment components. Essentially,
                  the building and equipment components are placed as to
                  maximize truck and rail access. Generally, the main processing
                  plant will be located near the site's center with the corn
                  storage bins located to the north or near the railroad line
                  and the ethanol tank farm located on the site's northwest
                  corner. Reference to the enclosed site plan is essential in
                  understanding the improvement's placement.

             c.   Building-to-Site Ratio: This component is generally not
                  applicable to this particular property type as far more land
                  exists than even needed for the plant, especially if Parcel B
                  is added to the entire site size. However, the additional land
                  is not deemed excess or surplus land as the area market simply
                  does not have the economics as to justify value enhancement
                  for additional lands.

             d.   Parking Lot and Parking Requirements: Two lined parking lots
                  will be provided, one located at the scale house and one at
                  the administrative office building. The parking is sufficient
                  for both uses. Additionally, various areas throughout the site
                  can be used for parking. Likewise, the parking requirements
                  are not a significant factor in this particular property type.

             e.   Other Site Improvements: The majority of the site area will be
                  improved with compacted rock based material as to provide
                  sufficient support for the considerable on-site truck traffic.
                  Some landscaped areas will be installed around the site's
                  perimeter, especially along the east side as to enhance the
                  site's initial appearance. Other significant site improvements
                  will include the rail line and earthen bermed retaining walls
                  around the ethanol tank farm.

       5.    Plant Design and Utilization:

             The completed ethanol plant is/will be designed, constructed, and
             finished to accommodate a state-of-the-art ethanol fuel production
             facility with an initial production capacity of 40 million gallons
             per year. Liquid ethanol or ethyl alcohol can be used as a fuel
             when blended with gasoline or even in its original state. Ethanol
             is made by fermenting almost any material that contains starch such
             as corn, sorghum, potatoes, sugar cane, etc. The subject ethanol
             plant will be utilizing grain corn as its starch material. Some
             understanding of the dry mill corn ethanol production process is
             necessary in the valuation analysis. The following five step
             production process was provided by the developer or Broin and
             Associates, Inc.:

             Step 1. Milling
                  -   Objective: The physical breakdown of the corn kernel using
                      mechanical processes.

                  a.  Dried, shelled corn as received is checked for moisture
                      content, bushel weight, and foreign matter. Corn is
                      cleaned in a scalper and then passed through

<Page>

                                                                              35

                      hammermills, which grind it into fine powder called meal
                      to expose the starch to further downstream processing.

             Step 2. Liquefaction and Saccharification
                   -  Objective: Use of heat and enzymes to break down starches
                      into fermentable sugars.
                   a. The meal, mixed with water and alpha-amylase, passes
                      through cookers where the starch is liquefied.
                   b. Heat is applied to facilitate liquefaction.
                   c. Continuous cookers heat the mixture to 190 DEG.-195 DEG.
                      F, after which it is held At 190 DEG. F for three to five
                      hours. In a process that incorporates a jet cooker, steam
                      is injected in to the flow of mash to raise the
                      temperature and the pressure.
                   d. In the saccharification stage, the mash from the cookers
                      is cooled and glucoamylase is added to break the
                      multi-glucose chains into single glucose surgars.

             Step 3.    Fermentation
                   -  Objective: Conversion of sugar to carbon dioxide and
                      ethanol through yeast metabolization.
                   a. Fermentation is carried out in the batch mode where
                      fermentation tanks are filled with mash, yeasted, and left
                      to ferment for a period of time. (There will be four
                      550,000 gallon fermentation tanks.) After fermentation is
                      complete, the batch is transferred to the next step of the
                      process, the tanks are cleaned, and a new batch is
                      started.
                   b. The process of fermentation will be programmed for
                      approximately 48 hours.
                   c. The 692,000 gallon beer well maximizes the conversion for
                      starch to ethanol by allowing additional time for
                      fermentation to be completed. The larger beer well also
                      acts as a buffer between fermentation and distillation.

             Step 4.  Distillation and Dehydration
                   -  Objective: Use of heat and molecular sieve dehydrators to
                      separate ethanol from water.

                   a. The fermented mash (beer) contains about 14% to 16%
                      ethanol plus solids from unfermented corn solids and yeast
                      cells.
                   b. The beer is pumped into a distillation column (rectifier)
                      where the ethanol is boiled and separated from a watery
                      residue called stillage.
                   c. The ethanol vapor exits the top of the continuous process
                      distillation columns at approximately 190 proof.
                   d. The stillage is pumped out of the bottom of the columns,
                      separated and dried through a couple of other steps in the
                      process, and eventually becomes the Distillers Dried
                      Grains with Solubles (DDGS) product.
                   e. The 190 proof ethanol is run through molecular sieve
                      dehydrators for the final step of purification. This
                      system acts like a sponge to remove the remaining water to
                      yield a final ethanol product of at least 199.5 proof.
                   f. Anhydrous ethanol produced by the sieves is metered to a
                      tank farm for storage. Each tank of production is
                      segregated until lab tests have verified the quality.
                      After quality control, the fuel ethanol is denatured to
                      BATF formulations as trucks are loaded. Currently, the
                      fuel ethanol is blended with five gallons of denaturant
                      per one hundred gallons of ethanol.

             Step 5.  By-Product Recovery
                   -  Objective: The use of heat and mechanical processes to
                      process non-fermentable corn components into saleable feed
                      products.

                   a. The stillage leaves the bottom of a distillation column
                      and travels to the centrifuge where it is separated into
                      cake (wet solids) and thin stillage (liquid).
                   b. Evaporators boil away most of the moisture in the thin
                      stillage leaving a thick syrup containing all of the
                      dissolved solids from the mash.
                   c. The syrup is mixed with the centrifuge cake and the
                      mixture is dried to about 10% moisture for sale as
                      Distillers Dried Grains with Solubles (DDGS), a high value
                      animal feed.

             Generally, one 56 pound bushel of No. 2 yellow corn yields about
             (1) 2.6-2.8 gallons of 200 proof ethanol, (2) 17-18 pounds of DDGS,
             and (3) 17 pounds of carbon dioxide. The plant's significant

                      horsepower fire-tube boilers (two in operation, one on
                      standby) 2 air compressors, and water treatment equipment.
                      Water treatment includes a dual R.O. system and green sand
                      filters. Green sand filter backwash water connects to a
                      settling basin before being discharged with the R.O.
                      concentrate water and cooling tower bleed-off water. R.O.
                      water is used primarily for cooling tower make-up and
                      boiler make-up. Process wastewater is filtered and run
                      through a separate R.O. in the mechanical building to be
                      purified into boiler make-up water. The concentrate from
                      this R.O. is sent through the methanator and then used as
                      part of the water needed to slurry the corn flower.

             The industry specifications for the furniture, fixtures, and
             equipment (FF&E) were not provided. Rather, the equipment
             description is best detailed by referencing the borrower/owner
             provided "Contract Schedule of Values" (complete copy enclosed in
             the following Cost Approach) and the previously referenced
             "Millwright and Mechanical Package" plans. The plans accurately
             depict the location of the equipment throughout the plant but,
             again, specific details are not provided. Even so, the information
             provided through the combination of these two sources is sufficient
             for this analysis. It can only be assumed that the building
             components and equipment will be properly sized for the plant's
             planned capacity.

                                                                              38

             Generally, the major building enclosures will be steel framed with
             colored steel exterior wall and roof covering, poured concrete
             ground level floors, considerable structural support steel for
             mounting necessary equipment and fixtures, and generally unfinished
             production areas with the exception of insulation and liners. The
             only exceptions would be the finished office areas, employee areas,
             control room and lab, scale building, etc. Lastly, it can only be
             assumed that the collective design and utilization will result in
             an efficiently operated ethanol fuel plant as the project developer
             or Broin & Associates are industry leaders in this particular
             market segment. (Further specifics relating to their background
             will be detailed in the following Highest and Best Use Analysis.)

             Again, reference to the enclosed exhibits more accurately depict
             the plant's design, layout, and even the plant equipment's location
             and use. The following details primarily the main building
             component's structural and finish components. Their perceived
             overall quality, physical condition, and functional utility will
             also be addressed in this discussion.

       6.    Structural Description:

             a.   Basic Frame: A nationally known cost service or MARSHALL
                  VALUATION SERVICE (MVS) classifies the building's basic
                  construction as predominantly Class "S" with the exception of
                  the scale and administration buildings. Class S construction
                  is detailed by MVS as being primarily incombustible
                  construction featuring generally pre-engineered metal frame
                  buildings with metal exterior wall and roof cover. The scale
                  and administration buildings are classified as Class "D"
                  structures or buildings generally having wood frame or
                  combustible construction components. The majority of the
                  following description will apply to the process/distillation
                  and grains buildings as they comprise 93.5% of the total floor
                  area. The specific details for the scale and administration
                  buildings will follow.

             b.   Foundation Walls: Generally 18" wide poured concrete
                  foundation walls set on poured concrete spread footings below
                  the frost line.

             c.   Floor Structure: Six inch poured concrete slab over compacted
                  base.

             d.   Exterior Wall Construction and Finish: Rigid steel frame with
                  metal panel exterior wall cover. Generally, all interior walls
                  are then insulated with the bottom 10' covered with a panel
                  liner.

             e.   Roof Structure: Rigid steel frame.

             f.   Roof Insulation and Cover: Batt insulation sealed with vapor
                  barrier. Roof cover is metal panels. Complete gutter and
                  downspout systems also installed.

       7.    Interior Construction and Finish:

             Generally, minimal interior finish exists in most of the
             process/distillation and grains buildings other than the 10' high
             panel liners. However, select areas to include needed office areas,
             rest rooms, labs, control rooms, etc. are finished with standard
             tile flooring, and painted drywall and/or metal wall cover and
             drywall and/or suspended ceiling cover.

       8.    Mechanical Systems:

             The ethanol process, in itself, generates most all needed heat
             throughout these buildings with the exceptions of controlled
             employee areas. These areas have forced air heat with central air
             conditioning. Additionally, all plumbing, electrical, lighting, and
             complete wet fire protection system installed to service the plant.

                                                                              39

       9.    Scale and Administration Buildings:

             These two buildings will feature standard 2"x6" wood frame exterior
             wall construction with insulated poured concrete foundation walls
             and spread footings, four inch poured concrete floor over compacted
             base, brick veneer exterior wall cover with the exception of metal
             siding around the eave areas, and asphalt shingled roof cover.
             Interior will feature carpet and vinyl floor covering, painted
             drywall walls, and a suspended acoustical tile ceiling. HVAC will
             be provided by gas forced air furnaces with central air
             conditioning. Additionally, all other electrical, lighting, and
             plumbing needs will be installed.

       10.   Quality of Construction, Physical Condition, and Functional
             Utility:

             a.   Quality of Construction: The plans and specific construction
                  details, input provided by the project developer or Broin &
                  Associates, and even the inspection of the Dakota Ethanol
                  Plant located at Wentworth, South Dakota, suggest that "good"
                  quality will be apparent in this completed processing
                  facility. Specifically, the project developer or Broin &
                  Associates, Inc. have extensive knowledge in developing this
                  particular facility. Thus, this completed plant will have
                  quality equal to, if not exceeding most competitors within the
                  ethanol processing industry.

             b.   Physical Condition: New

             c.   Functional Utility: The last major building component that has
                  a significant impact on the property's overall appeal and
                  marketability is that of functional utility. Functional
                  utility is the ability of the improvements to be useful and to
                  perform the function for which they were intended according to
                  current market tastes and standards; the efficiency of a
                  building's use in terms of architectural style, design and
                  layout, traffic patterns, and the size and type of rooms.
                  (This definition was paraphrased from the Appraisal Institute,
                  THE DICTIONARY OF REAL ESTATE APPRAISAL, THIRD EDITION, page
                  155.)

                  Again, the project developer has incorporated a
                  state-of-the-art design which is undoubtedly consistent with
                  or, most likely, superior to the current market parameters for
                  this particular market segment. Reference to the enclosed site
                  plan will indicate that the plant even has the capability of
                  being expanded as allowances have been made for additional
                  corn and DDGS storage facilities. A virtual replica of this
                  facility was recently completed in Wentworth, South Dakota,
                  and, from all indications, the design or functional utility
                  has been exceptional. Thus, the market would also perceive
                  this completed plant as having exceptionally good functional
                  utility.

             d.   Summary: The completed plant will be new and offer quality and
                  functional appeal exceeding that normally found in this
                  particular market segment, especially if compared to older
                  ethanol plants. Considered collectively, the subject
                  property's overall appeal and marketability will be favorably
                  impacted by the completed improvements good characteristics.

       11.   Age:

             a.   Historical: New

             b.   Effective Age: New

             c.   Estimated Remaining Economic Life: A nationally recognized
                  cost manual or MARSHALL VALUATION SERVICE (MVS) reports on the
                  observed typical life expectancy of most types of
                  improvements. Ethanol processing plants are not specifically
                  detailed. However, it references manufacturing facilities with
                  most Class S

<Page>

                                                                              40

                  manufacturing facilities having life expectancies of about
                  40-50 years. This estimation of life expectancy was based on
                  appraisers' opinions and studies of actual mortality,
                  condition of survivors, and ages at which major reconstruction
                  or change of occupancy have taken place. These life expectancy
                  studies do not include cases of mortality from economic
                  obsolescence or poor business management. As detailed in
                  Section 97, page 5 of MVS, "(SOME OCCUPANCIES, SUCH AS HOTELS,
                  FAST FOOD RESTAURANTS, SERVICE STATIONS, ETC. ARE COMPLETELY
                  REMODELED OR REBUILT LONG BEFORE THE END OF THEIR USEFUL LIFE
                  AS A MATTER OF MARKETING POLICY.)" ECONOMIC life should not be
                  confused with an estimate of remaining physical life. Economic
                  life refers to the period of time in which improvements are
                  anticipated to contribute value to the site, while PHYSICAL
                  life refers to the period of time that the improvements are
                  anticipated to physically exist. The subject improvement's
                  REMAINING ECONOMIC life should approximate 40-50 years as they
                  will be new. The estimate of remaining economic life is
                  important because lenders typically require a remaining
                  economic life equal to or exceeding the term of a loan.

       12.   Floor Plans:

             The floor plans, the appropriate copies are located in the Addenda,
             were provided by the developer or Broin & Associates, Inc. Again,
             it must be emphasized that the appraisal will be based on the
             assumption that the improvements and furniture, fixtures, and
             equipment (FF&E) will be completed and/or installed per plans and
             specifications. Any significant deviation from the plans and
             specifications could render the appraisal and its results void.
             These plans provide considerably more specifics as it relates to
             the entire processing plant facility.

       13.   Representative Photographs of Similar Improvements:

             The following pictures, taken on September 18, 2001, are
             representative of the Dakota Ethanol Plant in Wentworth, South
             Dakota. This facility opened on August 1, 2001. These photographs
             provide a good visual representation of the subject improvement's
             respective composition and finish when complete.

I.     REAL ESTATE TAXES AND SPECIAL ASSESSMENTS DATA

             According to South Dakota state law, a property's real estate taxes
       are based on a formula originating from the County Director of Tax
       Equalization's interpretation of the property's estimated "true and full
       value". As of the inspection date, the property has been assessed only as
       vacant land with Parcel A having a tentative 2002 taxable value of
       $15,051 or $531.84/acre and Parcel B having a taxable value of $4,379 or
       $528.23/acre. The exact assessment level for the completed plant has yet
       to be determined. The owner/borrower has projected real estate taxes of
       about $960,000. They are detailed in the Business Plan which will be
       referenced in the following discussion. This expense computes to 2% of
       the approximate project cost or $48,000,000. This projected expense is
       deemed reasonable; it is probable that it will even be less once the
       total assessment process is complete. As of the inspection date, no
       unpaid special assessment existed.

<Page>

                                                                              44

J.     HIGHEST AND BEST USE ANALYSIS

             The previous discussion detailed the area and neighborhood markets
       and the subject property. Again, the premise for this valuation analysis
       must be stressed. The first appraisal objective is to develop an opinion
       of the completed subject property's market value assuming fee simple
       ownership even though the site is leased. Within the fee simple ownership
       interest concept, the "subject site" has been identified as two parcels
       totaling 36.59 acres. Again, Parcel B comprising 8.29 acres has limited
       utility and is carried simply as surplus land or additional land that
       allows for future expansion of the existing improvements. For this
       reason, the two parcels totaling 36.59 acres will be considered
       collectively as the "subject site".

             The highest and best use analysis attempts to identify the most
       PROBABLE and PROFITABLE, COMPETITIVE use to which the market and property
       can support; key determinants to the concept of value. Highest and best
       use is a market driven concept based on evidence collected from general
       data and analyzed to develop an opinion of a property's value. In
       essence, the Highest and Best Use Analysis reconciles all the previously
       assembled market information into the foundation on which market value
       rests.

             HIGHEST AND BEST USE of the subject real estate, as it will be
       considered in this report, is defined as:

             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 THE HIGHEST AND BEST USE MUST MEET ARE LEGAL
             PERMISSIBILITY, PHYSICAL POSSIBILITY, FINANCIAL FEASIBILITY, AND
             MAXIMUM PROFITABILITY.
             (Appraisal Institute, THE DICTIONARY OF REAL ESTATE APPRAISAL,
             THIRD EDITION: 171)

       Conclusions of highest and best use for real estate are normally made
       according to two premises. The first premise assumes that the site is
       VACANT and AVAILABLE for development and the second premise addresses the
       highest and best use of the site AS IMPROVED. In most cases, as long as
       the value of the improved site is greater than the value of the
       unimproved site, the highest and best use of the site is as improved.

             The highest and best use of a specific property is shaped by the
       competitive forces within the

<Page>

                                                                              45

       market location and, therefore, the analysis and interpretation of
       highest and best use is an economic study of those market forces focused
       on the subject property. Thus, the four criteria that formulate a
       property's highest and best use, as specified in the definition, must be
       detailed and are normally considered sequentially. The first two tests of
       legal permissibility and physical possibility MUST be applied before the
       remaining tests of financial feasibility and maximum productivity. Again,
       the four criteria formulating a property's highest and best use are:

             1.   Legally permissible: What uses are permitted by zoning and
                  deed restrictions on the site in question?

             2.   Physically possible: What uses of the subject site are
                  physically possible as dictated by the physical aspects of the
                  site itself?

             3.   Financially feasible: Which possible and permissible uses will
                  produce a net return to the owner of the site?

             4.   Maximally productive: Among the feasible uses, which use will
                  produce the highest net return or highest present worth?

       These four criteria are now detailed and applied to the subject site
       according to the premise that it is vacant and available for development
       and it is improved to its present or proposed state of improvement.

       HIGHEST AND BEST USE AS VACANT:

             Under this premise, the site's highest and best use AS THOUGH
             VACANT is defined as:

             AMONG ALL REASONABLE, ALTERNATIVE USES, THE USE THAT YIELDS THE
             HIGHEST PRESENT LAND VALUE, AFTER PAYMENTS ARE MADE FOR LABOR,
             CAPITAL, AND COORDINATION. THE USE OF A PROPERTY BASED ON THE
             ASSUMPTION THAT THE PARCEL OF LAND IS VACANT OR CAN BE MADE VACANT
             BY DEMOLISHING ANY IMPROVEMENTS.
             (Appraisal Institute, THE DICTIONARY OF REAL ESTATE APPRAISAL,
             THIRD EDITION: 171)

       The four criteria formulating the site's highest and best use, assuming
       it were vacant, are now applied:

       1.    Legally Permissible:

             The first step in determining the subject site's highest and best
             use, assuming it were vacant, is addressing legal considerations or
             private restrictions, zoning, building codes, environmental
             regulations, etc. Typically, the most obvious legal consideration
             that affects development of a particular site is zoning. The
             previous discussion detailed that the subject site is zoned "C-I or
             Commercial/Industrial". This commercial zoning district allows a
             significant number of commercial and/or industrial uses but all are
             allowed only through a conditional use permit. The only permitted
             uses are those allowed in the agricultural zoning district. No
             other legal considerations were noted that would restrict site
             development.

       2.    Physically Possible:

             The two most significant subject site characteristics that would
             readily impact its probable use(s) would be that of site size and
             site location. Most other physical site characteristics relating to
             elevation, drainage, site preparation, and even the site
             encumbrances would not have a measurable impact on probable uses.
             The site size at 36.59 acres is sufficient so that single or
             multiple uses would be possible. Regardless of the probable number
             of uses that could exist, its location or two miles northwest of
             the city limits of Big Stone City is still deemed a predominantly
             agricultural use area.

       3.    Financially Feasible:

             The predominant land use outside the city limits is that of
             agricultural farmland with the exception of scattered rural
             residences and scattered commercial/industrial single land users.
             The subject site is located next to one of the area's largest
             commercial land users or the Big Stone Power Plant, built in 1975.
             Thus, 26 years was needed before another somewhat similar
             commercial/industrial user located to this area. Essentially, the
             majority of the area land has been and continues to be agricultural
             in nature. Thus, the location still suggests continued agricultural
             use as being probable.

       4.    Maximally Productive:

             Selecting one particular use available within the broader
             agricultural market that would be maximally productive is dictated
             by the current balance of supply and demand. As previously noted,
             the site's zoning allows for commercial and/or industrial users but
             the likelihood of this type of development occurring is greatly
             minimized by the limited demand. Thus, the site's rural location
             suggests that continued agricultural use would be probable until
             such time that, IF and WHEN demand so evolved, the site would be
             commercially or industrially developed.

       5.    Site's Highest and Best Use Conclusion if Vacant:

             Based on the preceding analysis, the subject site's highest and
             best use, if vacant, is concluded to be agricultural related
             development. This use is legally permitted, physically possible
             within the site's constraints, financially feasible, and demand
             would still be sufficient within the area market to represent
             maximum economic productivity.

       HIGHEST AND BEST USE AS IMPROVED:

             The second premise addresses the site's highest and best use AS
             IMPROVED, defined as:

                  THE USE THAT SHOULD BE MADE OF A PROPERTY AS IT EXISTS. AN
                  EXISTING PROPERTY SHOULD BE RENOVATED OR RETAINED AS IS SO
                  LONG AS IT CONTINUES TO CONTRIBUTE TO THE TOTAL MARKET VALUE
                  OF THE PROPERTY, OR UNTIL THE RETURN FROM A NEW IMPROVEMENT
                  WOULD MORE THAN OFFSET THE COST OF DEMOLISHING THE EXISTING
                  BUILDING AND CONSTRUCTING A NEW ONE. (Appraisal Institute, THE
                  DICTIONARY OF REAL ESTATE APPRAISAL, THIRD EDITION: 171)

       The analysis of highest and best use as improved applies the same four
       tests of legal permissibility, physical possibility, financial
       feasibility, and economic profitability to the subject site as proposed
       or presently being improved or that of an ethanol fuel plant.

       1.    Legally Permissible:

             The subject site is being improved with an owner occupied ethanol
             fuel plant or a use that is allowed only through a conditional use
             permit by zoning. The March 12, 2001, teleconference meeting of the
             Grant County Planning Commission approved the use. No other known
             unusual easements or other legal restrictions exist that would
             prohibit the completed subject improvement's development and/or
             continued use. Thus, legal permissibility is suggested.

       2.    Physically Possible:

             The four previously detailed building components will total 73,398
             square feet of main floor footprint area but it does not include
             the grain storage buildings. Even so, the building components will
             occupy only about 6% of Parcel A. More importantly, the completed
             plant's physical design, site placement, and access are entirely
             appropriate within the site's physical constraints. Thus, the
             site's proposed use or that of an ethanol fuel plant is physically
             possible.

       3.    Financially Feasible:

             The anticipated market value of the improved site or that of a 40
             million gallon ethanol fuel plant will far exceed the site's market
             value, if it were vacant. The following analysis will detail that
             the site's underlying market value is insignificant at about
             $20,000-$30,000 as compared to a total project cost approximating
             $45-$50 million. This ethanol plant will have the capability of
             generating income (in this particular property it would be in the
             form of business income generated by operation of the plant to
             include both the improvements and non-real property items) in
             excess of supporting the site's underlying market value, as will be
             demonstrated in the following Income Analysis. The subject site's
             improved state or that of an ethanol fuel plant will conform to the
             neighborhood's already established site uses. Specifically, the
             adjacent land user or the Big Stone Power Plant offers a similar
             use and other, more localized commercial/industrial users are noted
             throughout the broader market. Lastly, the owner/borrower/developer
             is, evidently, of the opinion that the local market is sufficient
             to support the proposed use as being financially feasible. Thus,
             disregarding the site's proposed use or that of an ethanol fuel
             plant is not realistic, implying that this proposed use is
             financial feasible.

       4.    Maximally Productive:

             The subject site's proposed use or that of a 40 million gallon
             ethanol fuel plant is legally permissible, physically possible, and
             all indications are that it should be financially feasible. Even
             so, a sufficient overview of the overall ethanol market should be
             presented to determine if, when complete, the use will be maximally
             productive. This overview should include some insight as to the
             national, regional, and local ethanol market using available
             information. Much of the following information was paraphrased
             and/or copied from various internet websites relating to the
             ethanol fuel industry. These sources include the American Coalition
             for Ethanol (ACE), Broin & Associates website and related links,
             the Renewable Fuels Association (RFA), etc.

             HISTORY - Ethanol has been around since ancient times when it was
             used primarily as an intoxicating drink. During the late 1800's,
             ethanol in the United States was used primarily for lamp fuel with
             sale exceeding 25 million gallons per year. The first large scale
             use of ethanol as a fuel occurred during the early 1900's when
             petroleum supplies in Europe were short. In the U.S., Henry Ford's
             Model T and other early 1920's automobiles were originally designed
             to run on alcohol fuels. Hitler and the U.S. relied on ethanol to
             power their armies during

                                                                              48

             World War II. After World War II, oil prices decreased which caused
             the use of ethanol to decrease. The limited use of ethanol
             continued until the oil crisis developed in the 1970's.

             Increased use of ethanol as a fuel has grown significantly since
             the late 1970's. It was first used as a product extender because of
             gasoline shortages. In 1973, the Organization of Petroleum
             Exporting Countries (OPEC) caused gasoline shortages by increasing
             prices and blocking shipments of crude oil to the United States.
             The OPEC action called attention to the fact that the United States
             was extremely dependent on foreign oil. The focus shifted once
             again to alternative fuels such as ethanol. At that time, gasoline
             containing ethanol was called gasohol. Later, when gasoline was
             more plentiful, ethanol was introduced to increase the octane
             rating and the name gasohol was dropped in favor of names
             reflecting the increased octane. Unleaded plus or super unleaded
             are two examples of names used today.

             Ethanol, when used as a gasoline component, improves combustion and
             reduces carbon monoxide emissions. Use of ethanol benefits the
             areas of the U.S. that are considered to exceed Environmental
             Protection Agency air quality standards during the winter months.
             Some studies have indicated that, used in a correctly formulated
             fuel, the use of ethanol can also reduce emissions which contribute
             to the formation of smog.

             More recently, ethanol supporters have focused attention on other
             advantages. One of these advantages is ethanol's ability to provide
             octane while replacing other environmentally harmful components in
             gasoline. Other studies suggest that using ethanol can slow global
             warming. Ethanol reduces imports by replacing imported gasoline and
             crude oil. Reducing gasoline and crude oil imports reduces American
             dependence on foreign oil. According to a recent poll conducted by
             Research Strategy Management, 75% of American voters believe that
             the country needs to do something to reduce its dependence on
             foreign oil.

             Today, ethanol is widely used and available in most areas of the
             U.S. Ethanol is contained in over 11% of all gasoline sold in the
             United States. It is or has been marketed by such companies as
             Exxon, Sunoco, Texaco, Amoco, Mobile, ARCO, Super-America, Chevron,
             Union, Shell, and Phillips, as well as numerous independent
             marketers. Since ethanol was first sold in 1978, American consumers
             have driven more than two trillion miles (80,000 trips around the
             world) on ethanol blended gasoline.

             The 1990's experienced the introduction and operation of flexible
             fuel vehicles (FFV). FFV vehicles are capable of operating on E-85,
             which is a blend of 85% ethanol and 15% unleaded gasoline. The Ford
             Taurus FFV car was introduced to Iowa in 1996 and was used in the
             state fleet and by some city governments. They became available
             commercially shortly thereafter. FFV's, designed for versatility,
             will operate on unleaded gasoline or any mixture of gasoline and
             ethanol up to an 85% blend.

             The key component in a flexible fuel vehicle is a sensor which
             determines the percentage of ethanol in the fuel and, with the help
             of a computer, makes adjustments automatically for best performance
             and emissions. Beginning with the 1998 model year, Chrysler offered
             FFV minivans. Ford continues to offer the Taurus and added Windstar
             and Ranger in 1999. Explorer and Sport Trac were offered in 2001.
             General Motors Chevrolet S10 and Sonoma, Isuzu Hombre, and Mazda
             B3000 were offered in an FFV version beginning in 2000.

             Two specific pieces of federal legislation, the Clean Air Act
             Amendments of 1990 and the Energy Policy Act of 1992 mandated the
             phased-in adoption of cleaner-burning vehicles. These federal laws
             required that state, municipal, and private fleets must meet
             stricter emission guidelines starting in 1998. One way this was
             accomplished was by replacing existing vehicles with newer
             technology like flexible fuel vehicles. One portion of the law
             requires 70% of all new fleet vehicle purchases meet these new
             standards in 2000.

             Auto manufacturers were also required to meet the new standards.
             Beginning in 1996, new model vehicles were equipped with on-board
             diagnostic monitoring systems capable of

                                                                              49

             monitoring tailpipe and evaporative emissions. New computer
             technology made this possible.

             WHY ETHANOL NOW? - Ethanol use and production has increased
             considerably during the 1980's and 1990's. Growth in use of the
             E-10 blend has taken place because the fuel performs well in
             automotive engines and is competitively priced with "conventional"
             gasoline.

             Proponents of ethanol have identified additional reasons for
             increased production and use, especially in the Midwest:
                  1.  It is in the national interest to reduce dependence on oil
                      imports. Trade deficits are decreased and it allows for a
                      dependable source of fuel if supplies would be cut off by
                      unfriendly countries.
                  2.  Farmers see an increased demand for corn which helps
                      stabilize prices.
                  3.  The quality of the environment improves. Carbon monoxide
                      emissions are reduced and lead and other carcinogens
                      (cancer causing agents) have been removed from gasoline.
                  4.  Car owners gain from increased octane in gasoline which
                      reduces engine knock. It also absorbs moisture and cleans
                      the fuel system.

             Those who challenge the use of ethanol as a fuel and challenge the
             incentives for ethanol argue that:
                  1.  It is more important to use grain for food to reduce world
                      hunger than to use ethanol as a fuel.
                  2.  The ethanol industry should not receive more favorable
                      incentives than manufacturers of other fuels.
                  3.  It damages or plugs fuel system components on some
                      vehicles and causes vapor lock, especially in hot weather.
                  4.  Foreign oil imports are reduced only slightly because of
                      ethanol use.
                  5.  It does little to reduce emissions and improve the
                      environment.
                  6.  It reduces motor fuel tax for ethanol blends.

             WORLDWIDE - Other countries are either producing and using ethanol
             in large quantities or are providing incentives to expand ethanol
             use. Brazil and Sweden are using large quantities of ethanol as a
             fuel. Some Canadian provinces promote ethanol use as a fuel by
             offering subsidies of up to 45 cents per gallon of ethanol. India
             is in the beginning stages of initiating the use of ethanol as an
             automotive fuel. In France, ethanol is produced from grapes that
             are of insufficient quality for wine production.

             Prompted by the increase in oil prices in the 1970's, Brazil
             introduced a program to produce ethanol for use in automobiles in
             order to reduce oil imports. The production and use of ethanol, a
             renewable fuel made from agricultural products, increases economic
             activity, creates jobs, helps to stabilize commodity prices, and
             boosts farm income. It can help us become independent from imported
             oil and improve our balance of trade.

             THE NATIONAL SCENE - The ethanol industry contributes positively to
             the U.S. economy, particularly rural communities where ethanol
             production is based. The economy is increased by providing direct
             and indirect jobs and increasing corn prices and rural income. The
             U.S. Department of Agriculture has concluded that a 100 million
             gallon ethanol facility could create 2,250 local jobs for a single
             community.

             A report by the Renewable Fuel Association about the economic
             outlook of the U.S. ethanol industry over a seven year period, 1996
             to 2002, concluded:

             -    The ethanol industry will add more than $2 billion per year to
                  the entire U.S. economy. The goods and services purchased by
                  ethanol producers represent increased demand for other
                  industries. These include purchases of grain, natural gas,
                  electricity, water, telephone, and accounting and legal
                  services.

             -    Net farm income for crop producers will be $2.2 billion, or
                  nearly 3% higher, each year because of ethanol production.
                  Increased demand for grain grown by American farmers provides
                  market support for prices and incomes.
             -    Ethanol supports 55,000 jobs. Ethanol production directly
                  accounts for over 5,800 jobs in the food/fuel processing
                  industry in 17 states. Additionally, the spending by ethanol
                  manufacturers on goods and services indirectly supports an
                  average of 48,900 jobs annually throughout all other
                  industries in the entire economy. Increases in ethanol
                  production offer enormous potential for overall economic
                  growth and additional employment in rural communities where
                  ethanol production is often based.
             -    Ethanol production will increase total household income by
                  $12.5 billion over the next seven years. The ethanol industry
                  directly pays $277 million in wages to employees. These
                  employees and their families spend this income, thereby
                  creating demand. The indirect impact of ethanol production
                  adds another $1.8 billion to household income annually.
             -    Ethanol generates $555 million of net tax revenue for the
                  Federal treasury annually through personal and business income
                  tax collections. Additional revenues, provided by taxes on
                  household and farm income that are generated and supported by
                  the ethanol industry, offset the cost of the partial ethanol
                  excise tax exemption for ethanol-blended gasoline.
             -    Ethanol contributes over $2 billion annually to the U.S. trade
                  balance. The U.S. currently imports 54% of its petroleum
                  demand. Use of ethanol reduces the trade deficit by about $1.3
                  billion annually by replacing imported MTBE. Another $800
                  million is gained annually due to export of the by-products of
                  ethanol, corn gluten feed and gluten meal.

             According to the American Coalition for Ethanol, more than $3
             billion has been invested in 60 ethanol production facilities
             operating in 20 different states across the country. Additionally,
             news reports have stated that: (1) The federal government has
             devoted $300 million to reimbursing farmers for production costs if
             they join cooperatives to produce renewable fuels. (2) President
             Bush's agenda includes creating a national energy policy, a
             positive sign for renewable fuels. Bush has a strong record of
             support for ethanol. As governor of Texas, Bush joined the
             Governor's Ethanol Coalition, which now has Nebraska Gov. Mike
             Johanns as its chairman. (3) President Bush has endorsed a
             continuation of the ethanol program that gives gasoline marketers
             and blenders a 5.3-cent reduction in the 18.3-cent federal tax on
             gasoline. Lastly, in a report unveiled by Johanns recently at a
             national ethanol conference, economist John Urbanchuk of
             Moorestown, NJ, estimated that quadrupling of ethanol production in
             the next 15 years would save U.S. consumers $57.5 billion a year,
             mostly by replacing imported oil.

             AGRICULTURE - Ethanol is made from farm-produced raw products which
             are usually in surplus. Corn is preferred in ethanol production and
             supplies most of the raw material needed. Ethanol production
             creates domestic markets for corn and, according to the USDA,
             ethanol production adds about 25 to 30 cents to every bushel of
             corn. Better prices mean less reliance on government subsidy
             programs and more income and independence for farmers. Ethanol
             production consumed about 600 million bushels of corn in 2000;
             ethanol production is the third largest user of corn, behind feed
             and export uses. Ethanol production uses about 7% of the nation's
             corn crop.

             As the domestic ethanol industry continues to grow, it is
             witnessing a surge in the construction of farmer owned ethanol
             production facilities. Farmers are realizing the added benefits to
             the ethanol industry through ownership of manufacturing plants.

             The production of ethanol does not mean less corn is available for
             food. Instead, ethanol production produces many valuable high
             protein food and feed co-products. An acre of corn (125 bushels)
             produces 313 gallons of ethanol, 1,362 pounds of 21% distillers
             grains, 325 pounds of 60% gluten meal, and 189 pounds of corn oil.
             Distillers grain can be used for feed in most every type of animal
             system and are used as a cost efficient, nutritional, digestible,
             and palatable protein feed for cattle, swine, and sheep.
             Approximately 1.4 billion tons of distillers grain is produced
             annually.

             PRODUCTION AND PRICE - Advances in technology in ethanol production
             process has substantially reduced costs. A shift to larger
             production plants along with improved yeast strains and enzymes
             have reduced cost by more than 50 percent. These innovations have
             lowered production costs from $1.40 per gallon in 1980 to less than
             $1.00 in 2001. Still newer plants and improved technologies have
             further reduced costs to an approximate current average price of
             $1.09 to produce one gallon of ethanol. This trend is expected to
             continue. The cost of producing ethanol will also be affected by
             corn yields, corn costs, and markets for co-products.

             Consumer prices at the service station pump for E-10 ethanol blend
             is usually the same price per gallon as unblended fuel. This is
             also true for E-85 blends. The price at the retail gas pump
             reflects federal and state tax exemptions, loan guarantees, and
             other government subsidies.

             Offsetting the cost of these tax incentives is a reduction in farm
             subsidies and the increase of tax revenues. According to the U.S.
             Department of Agriculture, if ethanol use does not continue to
             grow, "deficiency payments for corn and other program crops will
             increase by $580 million for crop year 1998 and $740 million by the
             year 2000"-more than the cost of the tax incentives. The economic
             activity attributable to the ethanol industry will generate $3.5
             billion in additional income tax revenue over the next five years
             -- $1 billion more than the cost of tax exemptions. The U.S.
             ethanol industry will create a net gain to the taxpayers of almost
             $4 billion over the next five years.

             The oil industry began receiving federal subsidies as early as 1916
             to promote development of an energy industry. As the oil industry
             became more profitable, the subsidy payments continued. In 1984,
             the oil industry received over $8.5 billion from the federal
             government. During the same time period, renewable fuel industries
             -- solar, wind, geothermal, hydropower, and alcohol fuels --
             received only $1.7 billion.

             The preceding suggests that sufficient demand should continue for
             the ethanol industry into the near future. According to the
             National Corn Growers Association, the market is ripe for expansion
             opportunities with their goal to add an additional 600 million
             bushels of ethanol production over the next ten years. A sufficient
             supply of raw product or corn exists nationwide and, if the prices
             can be enhanced by any measurable amount, production would even
             increase. Since 1981, ethanol production has increased from 175
             million gallons to record production of 1.63 billion gallons in
             2000 with more than 1.8 billion gallons anticipated for 2001 from
             more than 50 ethanol producing facilities operating in 20 different
             states.. The majority of the this growth has been within the last
             decade as ethanol production increased from 900 million gallons to
             the 1.63 billion gallons or an increase of 81%. According to an
             August 7, 2001, news release from the Renewable Fuels Association
             (RFA), more than a dozen ethanol plant facilities have opened since
             1999 and six major expansions to existing facilities were
             completed. To date, 57 ethanol plants can produce over 2 billion
             gallons of ethanol per year. Eleven additional ethanol plants are
             under construction with a combined annual capacity of 245 million
             gallons, 34 existing companies are undergoing expansion totaling
             235 million gallons, and dozens of additional proposed production
             facilities across the country are in various stages of development,
             engineering, and financing. Annual ethanol production capacity is
             expected to reach 3.5 billion gallons in 2003. Ethanol-blended fuel
             sales now represents over 11% of all automotive fuels sold in the
             United States. As stated by Ron Miller, Chairman of the Renewable
             Fuels Association, "NEW PLANTS SCHEDULED TO BEGIN PRODUCTION IN
             2001 WILL CONTRIBUTE TO THE INDUSTRY'S ABILITY TO RESPOND TO
             GROWING MARKET DEMAND FOR CLEAN BURNING OCTANE AND OXYGENATES.
             IMPORTANTLY, THESE NEW FACILITIES WILL PROVIDE MUCH-NEEDED ECONOMIC
             STIMULUS TO RURAL COMMUNITIES FACED WITH RECORD LOW COMMODITY
             PRICES AND SHRINKING EXPORT MARKETS."

             ETHANOL IN SOUTH DAKOTA (paraphrased from the South Dakota Corn
             Growers website) - Although the State of South Dakota does not
             mandate gasoline outlets to sell ethanol, nearly all gasoline
             outlets offer consumers the choice to purchase gasoline containing
             10% ethanol.

<Page>

                                                                              52

             In addition, a number of stations across the state also offer
             consumers the choice to purchase gasoline containing up to 85%
             ethanol for specially designed flex fuel vehicles. Consumers should
             feel secure knowing that ethanol blends of up to 10% are approved
             under the warranties of all major auto manufacturers, domestic and
             foreign, marketed in the U.S.


             Beyond gasoline outlets selling ethanol, South Dakota has and is
             achieving success with the planning and development of ethanol
             plants in various parts of the state. Part of the reason ethanol
             has achieved a large degree of success is attributable to the
             creation of the ethanol producer incentive fund, which sustains
             ethanol's development in the state and South Dakota's $.02 per
             gallon fuel tax exemption for ethanol blends. (According to the
             borrower's Business Plan, "THE STATE OF SOUTH DAKOTA PROVIDES A
             PRODUCTION INCENTIVE OF TWENTY (20) CENTS PER GALLON UP TO A
             MAXIMUM $1 MILLION PER YEAR. A PLANT IS ELIGIBLE TO RECEIVE A
             MAXIMUM OF $10 MILLION." In 1999, South Dakota produced 16 million
             gallons of ethanol. Beginning the twenty-first century, South
             Dakota will produce 68 million gallons of ethanol. South Dakota's
             annual ethanol production is projected to total 218 million gallons
             by 2004.

             South Dakota currently has four ethanol plants operational in the
             communities of Aberdeen, Huron, Scotland, and Wentworth. These four
             plants are capable of producing 68 million gallons of ethanol
             annually. In addition to these plants, other ethanol plants are in
             various stages of development; in the communities of Watertown,
             Rosholt, and Milbank, plants are under construction; in Chancellor
             they will be breaking ground in the spring of 2002; Pierre is just
             ready to start selling shares; and Mitchell is in the research
             stages of the project. If all these plants come to fruition, South
             Dakota will have the capability of supplying over 258 million
             gallons of ethanol annually to South Dakotans and their
             counterparts across the U.S.

             DEVELOPMENT OF SUBJECT PROPERTY OR NORTHERN LIGHTS ETHANOL PLANT
             (Much of the following information was detailed in the borrower's
             "Business Plan".) Northern Growers Cooperative, now known as
             Northern Lights Ethanol, LLC (NLE), stemmed from a steering
             committee that was formed by several area corn farmers and the
             civic leaders in the Grant County area. This group focused on the
             low prices paid to producers for agricultural products. The
             steering committee began researching the possibility of
             constructing and operating a dry mill ethanol plant in the Grant
             County, South Dakota area. The committed elected a temporary Board
             of Directors and established a non-profit corporation to study the
             feasibility and profitability of a plant within the area. This
             study included tours of various corn production facilities in the
             area, availability of critical elements to a successful plant such
             as rail service, water quality, low cost power, site drainage and
             other factors.

             The vision eventually evolved into the formation of a limited
             liability corporation and membership stock was then sold with a
             minimum purchase of 5,000 shares per member available. The equity
             drive raised $18,520,000 with about 700 members. Northern Lights
             Ethanol then selected Broin Enterprises, Inc. and its affiliates to
             design and build the facility (through their affiliate Broin &
             Associates, Inc.), to manage the business operations and facilities
             (Broin Management, LLC), and market the ethanol (Ethanol Products,
             LLC).

             BROIN ENTERPRISES, INC. (BEI) owns and operates an 8.5 million
             gallon per year fuel ethanol plant in Scotland, South Dakota. BEI
             employs 32 individuals and has gross revenues in excess of
             $10,000,000 annually. In addition to producing ethanol, the plant
             generates 23,000 tons of Distillers Dried Grains and compresses
             more than 16,000 tons of Liquid Carbon Dioxide annually. BEI
             operates as a full scale production plant in addition to a research
             and development facility for ethanol process improvement projects.
             Owners of the company are Robert, Jeff, Todd, and Lowell Broin. The
             company has grown from 1 million gallons per year capacity to 8.5
             million gallons per year capacity since its inception.

             BROIN AND ASSOCIATES, INC. (B&A) is an engineering and construction
             firm specializing in the design, engineering, construction, DCS
             system configuration, employee training, and plant start-up of new
             ethanol production facilities in the Midwest. Broin and Associates

             formed in 1991 to fulfill a need for knowledgeable, experienced
             individuals specializing in the design and construction of ethanol
             plants. A Contract for Future Services has been signed with Broin
             and Associates, Inc. Other projects completed to date by B&A
             include:

             1.   The design, construction, and start-up of a 4 million gallon
                  per year capacity ethanol plant for HEARTLAND GRAIN FUELS,
                  L.P. in Aberdeen, South Dakota in April of 1993. The Aberdeen
                  plant has been very successful to date. The facility was
                  constructed $500,000 under budget, turned a profit in its
                  first full month of operation, and operated at 20% greater
                  than design capacity in its first year. The plant has since
                  completed an expansion and is presently operating at 8.5
                  million gallons of production.

             2.   In 1994, completed the expansion of the BROIN ENTERPRISES
                  ethanol plant in Scotland, South Dakota, from 3 to 6 million
                  gallons of annual capacity. It is currently operating at over
                  8.5 million gallons per year. The expansion has been very
                  successful, operating at 115% of design capacity within 90
                  days. The Scotland facility also turned a profit in its first
                  month of operation.

             3.   In 1995, completed the design, engineering, construction
                  oversight, DCS system configuration, employee training, and
                  plant start-up services for the HEARTLAND CORN PRODUCTS 10
                  million gallon ethanol plant in Winthrop, Minnesota. The plant
                  came on-line in April, reaching full capacity in just 8 days.
                  The 16 day performance guarantee was completed 32 days later
                  and the plant is currently operating at 60% over design
                  capacity.

             4.   In 1996, Broin and Associates completed the design,
                  engineering, construction oversight, DCA system configuration,
                  employee training, and plant start-up services for the AL-CORN
                  CLEAN FUEL 10 million gallon ethanol plant in Claremont,
                  Minnesota. The Al-Corn facility is the first in the country
                  that uses traditionally high-yielding technologies and is not
                  connected to a waste treatment facility. Operations have been
                  very successful and the Al-Corn plant is currently operating
                  in excess of 140% of design capacity.

             5.   In 1997, Broin and Associates completed turn-key design and
                  construction of an 11.5 million gallon per year ethanol plant
                  for ETHANOL2000, LLP in Bingham Lake, Minnesota. The plant
                  came on -line in late June and has been very successful. By
                  December 31st, the plant was able to declare a $900,000
                  dividend after only six months of operation. The plant
                  completed a $15,400,000 expansion in August 2000 increasing
                  the nameplate capacity to 27 million gallons per year.
                  Original $2.00 cooperative stock has recently been sold for
                  $4.98/bushel.

             6.   In 1998, Broin and Associates completed turn-key design,
                  engineering, and construction oversight for the PRO-CORN LLC
                  12 million gallon ethanol plant in Preston, Minnesota. The
                  plant reached nameplate capacity in only seven days, turning a
                  profit in its first month of operation. The plant was able to
                  declare a dividend after only four months of operation and is
                  presently running at 60% over design capacity.

             7.   Also in 1998, Broin and Associates completed turn-key design,
                  engineering, and construction oversight for the AGRI-ENERGY
                  LLC 12 million gallon ethanol plant in Luverne, Minnesota. The
                  plant reached nameplate capacity in only six days, also
                  turning a profit in its first month of operation. Operations
                  at Agri-Energy have been highly successful, with the plant
                  currently running in excess of 60% over design capacity.

             8.   In 1999, Broin and Associates completed the turn-key design,
                  engineering, and construction oversight for the EXOL 13
                  million gallon ethanol plant near Albert Lea, Minnesota. The
                  plant came on-line in late March and was operating at design
                  capacity in 5 1/2 days. The 10 day performance guarantee was
                  completed in the first

                  10 days of distillation operations. Within three weeks, the
                  plant was operating in excess of 20% over design capacity. The
                  plant is currently running in excess of 50% over design
                  capacity.

             9.   In 2000, Broin and Associates completed the turn-key design,
                  engineering, and construction oversight for the NORTHEAST
                  MISSOURI RAIN PROCESSORS, LLC 15 million gallon per year
                  facility in Macon, MO. The plant came on-line on May 8, 2000.
                  It is running at 115% of design capacity after only 2 months
                  of operation and is improving weekly.

             10.  In 2001, Broin and Associates designed and built three
                  projects to include the GOLDEN TRIANGLE ENERGY, LLC (15
                  million gallon per year plant completed in February), DAKOTA
                  ETHANOL, LLC (40 million gallon per year plant completed in
                  August), and the EXOL plant expansion (13 to 36 million
                  gallons per year).

             BROIN MANAGEMENT, LLC is a management firm with more than 17 years
             of experience in the ethanol industry. Ethanol facility operations,
             microbiological research, grain hedging, mass in-put purchasing,
             and on-going professional support are specialties of the group,
             along with expertise in the finance and income tax arenas. Current

             ETHANOL PRODUCTS, LLC is engaged in marketing, supply,
             distribution, fuel blending, trading, risk management, and market
             development of fuel ethanol for use in motor gasoline throughout
             the United States. Their primary focus is to develop new
             value-added markets for ethanol and to improve the value of ethanol
             in existing markets. Knowledge of customers, suppliers, substitute
             products, and changing industry structure are important components
             of developing a successful marketing strategy. Ethanol Products
             advantages include concentrated experience and extensive market
             coverage in an affordable manner, the reliability of multi-point
             supply sourcing, and a diversified market base. It provides
             marketing for numerous plants in the region, allowing ethanol
             buyers to purchase ethanol from a single source. This "one call"
             sourcing will result in increased convenience, versatility, and
             security of supply for ethanol buyers and increased market
             knowledge and coverage for ethanol producers.

             The preceding discussion detailed that the subject site's proposed
             use or that of a 40 million gallon ethanol fuel plant is legally
             permissible, physically possible, financially feasible, and should
             be a productive use. The combination of a perceived favorable
             future ethanol market, knowledgeable ownership/management, a
             state-of-the-art processing plant, and a location providing needed
             product, transportation, labor force, etc. supports the observation
             that the subject site's proposed use or that of an ethanol fuel
             plant as being a definite probable use. This use definitely
             represents a maximally productive use as it will generate income
             far in excess of that needed to satisfy the return to the
             underlying site. The following detailed analysis of the income and
             expense projections also will conclude that the resulting net
             income is sufficient to support the total development costs. Thus,
             it is unlikely that any measurable functional or even external
             obsolescence will exist. For these reasons, it is determined that
             the subject site's proposed use or that of a completed ethanol fuel
             plant represents the site's highest and best use. This conclusion
             as to the site's highest and best use provides the basis for the
             following valuation process.

K.     VALUATION PROCESS (rev. 8-27-01)

             The previous discussion and analyses outlined the appraisal
       problem, detailed the subject's area market, neighborhood, and the
       specifics of the subject property, and concluded with a determination of
       the property's highest and best use. Achieving the goal of providing a
       reliable opinion of a property's going concern market value normally
       involves the three traditional valuation techniques or: (1) the Cost
       Approach, (2) the Sales Comparison Approach (also known as the Market
       Approach), and (3) the Income Capitalization Approach. These valuation
       techniques require the assemblage of market data pertaining to such
       factors as sale prices and asking prices of similar properties and
       unimproved tracts of land, cost data on similar construction, rental
       prices of similar properties, and current rates of return on similar
       investments.

             Each valuation technique used in developing a market value
       indication is not an independent system of valuation unrelated to the
       other approaches. The valuation process considered as a whole is
       comprised of integrated, interrelated, and inseparable techniques and
       procedures that have the common objective of providing a convincing and
       reliable market value indication. Each valuation technique normally
       references conclusions from the other technique(s). For these reasons, no
       predetermined sequence exists in the application of the three valuation
       techniques used in developing a market value indication.

             In this particular appraisal, only two valuation techniques used in
       developing a market value opinion will be utilized. The Sales Comparison
       Approach or a valuation technique that relies on the assemblage of
       similar property sales could not be used as few "similar" operating
       ethanol plants even exist and even within those that do exist, few, if
       any, have sold. Most state-of-the-art facilities have evolved only within
       the decade and, according to industry sources, none have sold. The
       alternative would be to use sales of similar use processing plants.
       However, the definite uniqueness of an ethanol fuel plant would create
       few similarities to most other types of processing plants. For these
       reasons, the Sales Comparison Approach could not be utilized.

                                                                              56

             Not utilizing the Sales Comparison Approach does NOT constitute
       departure from the UNIFORM STANDARDS OF PROFESSIONAL APPRAISAL PRACTICE
       (USPAP). Departure is invoked only when a valuation technique is
       applicable and is TYPICALLY used in developing the value opinion. Most
       market participants would not expect the application of the Sales
       Comparison Approach and most appraisal peers would not apply the Sales
       Comparison Approach.

             In this particular appraisal, only two valuation techniques or the
       Cost Approach and Income Capitalization Approach will be used in
       developing a market value opinion. Each technique is presented beginning
       with a brief explanation of the techniques and steps utilized. Data is
       assembled and analyzed, resulting in an indication of market value by
       each valuation technique. Finally, the market value indication by each
       valuation technique is evaluated and reconciled into an opinion of the
       subject property's going concern market value.

L.     COST APPROACH (Rev. 9-26-01)

             The Cost Approach is based on the premise that a property's value
       tends to reflect the site's market value plus the current cost to produce
       all the improvements, less any existing depreciation. The basic
       underlying principle in the Cost Approach is that of substitution. It
       affirms that a prudent buyer will pay no more for a property than the
       cost to acquire a similar site and construct improvements of equivalent
       desirability and utility without undue delay. Simply, an improvement's
       cost as of the appraisal's effective date plus the underlying site/land
       value provides a measure against which prices for similar improved
       properties may be judged.

             The steps used in the Cost Approach are:

       1.    ESTIMATE THE VALUE OF THE LAND AS THOUGH VACANT AND AVAILABLE TO BE
             DEVELOPED TO ITS HIGHEST AND BEST USE.

       2.    DETERMINE WHICH COST BASIS IS MOST APPLICABLE TO THE ASSIGNMENT:
             REPRODUCTION COST OR REPLACEMENT COST.

       3.    ESTIMATE THE DIRECT (HARD) AND INDIRECT (SOFT) COSTS OF THE
             IMPROVEMENTS AS OF THE EFFECTIVE APPRAISAL DATE.

       4.    ESTIMATE AN APPROPRIATE ENTREPRENEURIAL PROFIT OR INCENTIVE FROM
             ANALYSIS OF THE MARKET.

       5.    ADD ESTIMATED DIRECT COSTS, INDIRECT COSTS, AND THE ENTREPRENEURIAL
             PROFIT OR INCENTIVE, TO ARRIVE AT THE TOTAL COST OF THE
             IMPROVEMENTS.

       6.    ESTIMATE THE AMOUNT OF ACCRUED DEPRECIATION IN THE STRUCTURE AND,
             IF NECESSARY, ALLOCATE IT AMONG THE THREE MAJOR CATEGORIES:
             PHYSICAL DETERIORATION, FUNCTIONAL OBSOLESCENCE, AND EXTERNAL
             OBSOLESCENCE.

       7.    DEDUCT THE ESTIMATED DEPRECIATION FROM THE TOTAL COST OF THE
             IMPROVEMENTS TO DERIVE AN ESTIMATE OF THEIR DEPRECIATED COST.

       8.    ESTIMATE THE CONTRIBUTORY VALUE OF ANY SITE IMPROVEMENTS THAT HAVE
             NOT ALREADY BEEN CONSIDERED (SITE IMPROVEMENTS ARE OFTEN APPRAISED
             AT THEIR CONTRIBUTORY VALUE, I.E., DIRECTLY ON A DEPRECIATED-COST
             BASIS.)

       9.    ADD THE LAND VALUE TO THE TOTAL DEPRECIATED COST OF ALL THE
             IMPROVEMENTS TO ARRIVE AT THE INDICATED VALUE OF THE PROPERTY.

       10.   ADJUST THE INDICATED VALUE OF THE PROPERTY FOR ANY PERSONAL
             PROPERTY (E.G., FIXTURES, FURNITURE, AND EQUIPMENT) OR ANY
             INTANGIBLE ASSET VALUE THAT MAY BE INCLUDED IN THE COST ESTIMATE.
             IF NECESSARY, THIS VALUE, WHICH REFLECTS THE VALUE OF THE FEE
             SIMPLE INTEREST, FOR THE PROPERTY INTEREST BEING APPRAISED TO
             ARRIVE AT THE INDICATED VALUE OF THE SPECIFIED INTEREST IN THE
             PROPERTY.

             (Appraisal Institute, APPRAISAL OF REAL ESTATE, TWELFTH EDITION;
             Pg. 356)

             The first step in the Cost Approach is developing the site's MARKET
       VALUE OPINION, as if vacant and available to be developed to its highest
       and best use. The most common method in developing the site's market
       value is known as the Direct Market Comparison technique. This valuation

                                                                              58

       technique is based on the assumption that an informed purchaser will pay
       no more for a site than the cost of acquiring a similar site with the
       same utility (again, the principle of substitution).

             The first indication of the subject site's probable market value
       would be the price/value IMPLIED in the contractual "Ground Lease
       Agreement". A synopsis of this lease includes:

             1. Lessor:       Big Stone-Grant Industrial Development &
                              Transportation, L.L.C.

             2. Lessee:       Northern Lights Ethanol, LLC

             3. Lease Commencement Date: May 1, 2001

             4. Initial Term: 99 years but with "lessee's option to terminate".
                              Specifically, "LESSEE SHALL HAVE
                              THE RIGHT, BY WRITTEN NOTICE TO LESSOR GIVEN AT
                              LEAST 365 DAYS PRIOR TO: (A) THE EXPIRATION OF THE
                              FIRST FIVE-YEAR PERIOD OF THE TERM OF THIS LEASE;
                              OR (B) THE EXPIRATION OF ANY FIVE-YEAR PERIOD OF
                              THE TERM OF THIS LEASE THEREAFTER, TO TERMINATE
                              THIS LEASE AND SURRENDER ITS LEASEHOLD INTEREST
                              UNDER THIS LEASE TO LESSOR, EFFECTIVE ON THE
                              EXPIRATION OF THE FIVE-YEAR TERM AS SPECIFIED IN
                              THE WRITTEN NOTICE..."

             5. Options:      None

             6. Rent:         Years 1-5: $2,400/year
                              Years 6-99: "THE
                              RENTAL TO BE PAID BY LESSEE UNDER THIS LEASE
                              AGREEMENT SHALL BE ADJUSTED ON JANUARY 1, 2006,
                              AND EVERY FIVE YEARS THEREAFTER BY INCREASING THE
                              RENTAL IN EFFECT DURING THE IMMEDIATELY PRECEDING
                              FIVE-YEAR PERIOD BY FIVE PERCENT."

             7. Payment of Expenses: Tenant responsible for paying
                                      all expenses.

             Based on the preceding, the collected rent is "net" rent to the
       landlord in that the tenant is responsible for paying all expenses. The
       contractual rent can be "capitalized" into a market value indication
       applicable to the collective subject site or, again, about 36.59 acres.
       This capitalization process simply divides the net income by an
       appropriate return rate or overall capitalization rate or a valuation
       method commonly known as direct capitalization. (The direct
       capitalization methodology will be detailed in the following Income
       Approach.)

             Only two components are needed in formulating the site's market
       value indication through application of direct capitalization or (1) the
       net income and (2) an appropriate capitalization rate. Again, the
       contractual ground lease agreement is structured for a total of 99 years
       with fixed rent of $2,400 annual in the first five year segment with the
       rent increasing 5% per year for each additional
<Page>

                                                                              59

       five year segment. For the purpose of this analysis, the average annual
       rent over the 99 years of the lease will be used or about $4,000. This
       net income will then be capitalized using return rates or overall rates
       of 6% and 9%. The 6% land capitalization rate is more applicable to
       farmland, whereas, the 9% capitalization rate is more applicable to
       commercial or industrial land. (Support for these capitalization rates
       will be detailed in the following Income Approach.) The following details
       the application of this direct capitalization method to the subject
       site's net income, resulting in an indicated market value for the subject
       site:

<Table>
                                                            
             1.  Average Annual Rent                           $  4,000

             2.  Capitalized into Market Value
                 a.  Using 6% Rate:
                     $4,000 (I) DIVIDED BY .06 (R) =           $ 66,667
                 b.  Using 9% Rate:
                     $4,000 (I) DIVIDED BY .09 (R) =           $ 44,444

             3.  Indicated Price Per Acre. of Site Area
                 a.  $66,667 DIVIDED BY 36.59 acres =          $  1,822/acre
                 b.  $44,444 DIVIDED BY 36.59 acres =          $  1,215/acre
</Table>

             The next step or determining whether this indication of the subject
       site's market value or $1,200 to $1,800/acre is market supported is made
       by assembling and comparing recent sales of vacant sites that are
       considered to be similar to the subject site in physical characteristics,
       location, and, most importantly, use or potential use. The site's highest
       and best use if vacant was previously concluded to be that of
       agricultural farmland. Verification with the local Director of Tax
       Equalization or Mr. Darwin Conrad and South Dakota Department of
       Revenue's state representative or Mr. Kyle Helseth (605-367-5800)
       verified that "good" area cropland sells for approximately
       $600-$700/acre. Applying this value/price range to the subject site would
       indicate an initial contributory value indication of:

                  36.59 acres X $600/acre = $21,954, say, $22,000
                  36.59 acres X $700/acre = $25,613, say, $26,000

       Attempting to further quantify this price/value range with actual area
       market land sales is not entirely relevant as the site's underlying
       market value, especially as it relates to the total project cost of
       around $45-$50 million, is relatively insignificant.

<Page>

                                                                              60

             The lease analysis suggests a probable underlying site market value
       approximating $44,000 or about $1,200/acre to nearly $67,000 or about
       $1,800/acre as opposed to area farmland sales supporting prices/values at
       about $600-$700/acre. If vacant of the present improvements, it is
       unlikely that the site would be purchased for something more than area
       farmland. However, the site would have a comparatively smaller size and,
       for this reason, may be able to generate value/price near the upper end
       of the $600-$700/acre range. Based on this available market evidence, the
       subject site's fee simple market value is concluded at $25,000 or
       $683.25/acre. The site's fee simple market value conclusion is then
       carried through to the end of the Cost Approach.

             The next step in the Cost Approach is estimating the subject
       improvement's replacement or reproduction cost, as of the appraisal's
       effective date. In this particular appraisal, the REPLACEMENT COST is
       appropriate since, by definition, it:

             "THE ESTIMATED COST TO CONSTRUCT, AS OF THE EFFECTIVE APPRAISAL
             DATE, A BUILDING WITH UTILITY EQUIVALENT TO THE BUILDING BEING
             APPRAISED, USING CONTEMPORARY MATERIALS, CURRENT STANDARDS, DESIGN
             AND LAYOUT. WHEN THIS COST BASIS IS USED SOME EXISTING OBSOLESCENCE
             IN THE PROPERTY IS ASSUMED TO BE CURED." (Appraisal Institute, THE
             APPRAISAL OF REAL ESTATE, TWELFTH EDITION, Pg. 357)

       The replacement cost estimate is based on the use of current substitute
       materials and building techniques since they are functional in today's
       market and the structure's value and/or utility would not be diminished
       by their use.

             Several methods are available in which to estimate the replacement
       cost of a particular improvement or (1) the actual cost of the subject
       improvements could be utilized, if the costs were recent, (2) costs of
       reasonably similar newly constructed buildings could be assembled and
       compared, and/or (3) a national cost service could be referenced. In this
       particular appraisal, two sources or the owner provided actual or bid
       costs of the proposed improvements and indirect costs of reasonably
       similar newly constructed ethanol plants will be used to formulate the
       subject improvement's replacement cost estimate.

             The following four pages detail the owner/borrower provided costs.

             The total cost estimate of $48.8 million computes to $1.22/gallon
       of anticipated processing capacity or, as referenced in the industry,
       simply $1.22/gallon. The representative of Broin & Associates or Mr.
       Larry Ward verified that the estimated project cost for the 40 million
       gallon Dakota Ethanol Plant located at Wentworth, South Dakota, which
       opened on August 1, 2001, was $44,400,000 or $1.11/gallon. Actual
       expenditures at the Dakota Ethanol plant were somewhat higher than the
       projected cost but, yet, the initial projection of $1.11/gallon provides
       for an initial cost estimate indication. Broin Enterprises, Inc. was also
       involved in the development, construction, and operation of the
       Ethanol2000, LLP plant at Bingham Lake, MN, in July of 1997. This
       11,500,000 gallon facility was initially constructed at a cost of $19
       million or $1.65/gallon. In 2000, a 18,500,000 gallon/year expansion at a
       cost of $15.4 million was completed. Thus, this 30 million gallon plant
       was constructed at a cost of $34,400,000 or $1.15/gallon. Lastly, the
       Glacial Lakes Corn Processors ethanol plant broke ground on August 7,
       2001, in Watertown, South Dakota. According to the local newspaper
       article, this 40 million gallon facility is being built at a cost of $54
       million or $1.35/gallon. In summary, these three recently built or
       to-be-built ethanol plants indicate costs of $1.11/gallon, $1.15/gallon,
       and $1.35/gallon as compared to the subject's reported cost of
       $1.22/gallon.

             In summary, the owner/borrower is projecting total project costs at
       $48,800,000 or $1.22/gallon. This cost is supported by the available
       market evidence. Also, the anticipated subject plant's costs are deemed
       reliable in that the plant will be state-of-the-art, the costs are based
       on mostly known bids or projections, and the facility is being
       constructed by one of the industry experts. For the purpose of this
       analysis, the anticipated project cost of $48,800,000 will be used.

             The estimated replacement cost of $48,800,000 is all inclusive
       except for ENTREPRENEURIAL PROFIT or effort, sometimes referred to as
       DEVELOPER PROFIT, defined as:

             A MARKET-DERIVED FIGURE THAT REPRESENTS THE AMOUNT AN ENTREPRENEUR
             EXPECTS TO RECEIVE FOR HIS OR HER CONTRIBUTION TO A PROJECT; THE
             DIFFERENCE BETWEEN THE TOTAL COST OF A PROPERTY (COST OF
             DEVELOPMENT) AND ITS MARKET VALUE (PROPERTY VALUE AFTER
             COMPLETION), WHICH REPRESENTS THE ENTREPRENEUR'S COMPENSATION FOR
             THE RISK AND EXPERTISE ASSOCIATED WITH DEVELOPMENT. IN THE COST
             APPROACH, EXPECTED PROFIT IS REFLECTED AS ENTREPRENEURIAL PROFIT.

             Entrepreneurial profit -- sometimes referred to as developer profit
       -- represents the level of risk and expertise associated with the
       development of a project. Entrepreneurial profit can take the form of
       profit on a sale of the property, an additional return on an investment
       in an operating property, or use value to the entrepreneur. Ideally,
       measurements of entrepreneurial profit should be extracted directly from
       the market. In reality, this type of information is rarely available. It
       has been noted within this particular market segment that these plants
       are generally developed by owner/occupants/operators with many in recent
       years developed as farmer owned co-ops. Presently, farmer owned
       cooperatives account for about one-third of all U.S. fuel ethanol
       production. These cooperatives help to insure farmer members a
       value-added market for their crops and offer profit sharing dividends as
       the industry prospers. For these primary reasons, entrepreneurial profit
       is not normally included as part of the plant's cost. This observation
       was confirmed by Mr. Larry Ward of Broin & Associates. Mr. Ward indicated
       that entrepreneurial profit is anticipated in the plant's production or
       business. For these reasons, entrepreneurial profit will not be included.

             The next step in the Cost Approach is estimating depreciation
       accrued to the subject improvements. The concept of DEPRECIATION, as it
       relates to this appraisal, is defined as:

             "...A LOSS IN PROPERTY VALUE FROM ANY CAUSE; THE DIFFERENCE BETWEEN
             THE REPRODUCTION OR REPLACEMENT COST OF AN IMPROVEMENT ON THE
             EFFECTIVE DATE OF THE APPRAISAL AND THE MARKET VALUE OF THE
             IMPROVEMENT ON THE SAME DATE. IN REGARD TO IMPROVEMENTS,
             DEPRECIATION ENCOMPASSES BOTH DETERIORATION AND OBSOLESCENCE."
             (Appraisal Institute, DICTIONARY OF REAL ESTATE APPRAISAL, THIRD
             EDITION; pg. 96)

       Depreciation in an improvement can result from three major causes
       operating individually or in combination that include physical
       deterioration, functional obsolescence, and external obsolescence. The
       market recognizes the occurrence of depreciation but an accurate
       interpretation of how the market perceives the affect of the depreciation
       must be made.

             Physical deterioration occurs as a result of the natural aging
       process of a structure and may also result from the deferring of
       maintenance. Physical deterioration is a continual, on-going process--no
       matter how slow--that is the result of climatic exposure, use, and/or
       neglect. No physical deterioration would exist as the improvements would
       be new.

             Functional obsolescence refers to loss resulting from any reduction
       in an improvement's ability to be useful and to perform its intended
       function, ACCORDING TO CURRENT MARKET TASTES AND STANDARDS. Any reduction
       in the efficiency of a building's utility associated with, or derived or
       influenced from architectural style, design and layout, traffic patterns,
       the size and type of rooms, and/or outdated building techniques and
       materials are examples of functional obsolescence. The subject
       improvements or the ethanol fuel plant will be state-of-the-art as it
       relates to this particular industry. Additionally, the developer or Broin
       & Associates is well versed in plant design, construction, and operation
       as they are a leading expert in this particular improvement type. For
       these reasons, the completed plant will be state-of-the-art with no
       measurable functional obsolescence apparent.

             The third form of depreciation is termed EXTERNAL OBSOLESCENCE or:

             "...AN ELEMENT OF ACCRUED DEPRECIATION; A DEFECT, USUALLY
             INCURABLE, CAUSED BY NEGATIVE INFLUENCES OUTSIDE A SITE AND
             GENERALLY INCURABLE ON THE PART OF THE OWNER, LANDLORD, OR TENANT."
             (Appraisal Institute, THE DICTIONARY OF REAL ESTATE APPRAISAL,
             THIRD EDITION; pg. 128)

       External obsolescence can be either temporary as in an over-supplied
       market or permanent as in having proximity to an environmental disaster.
       Normally, external obsolescence is market-wide when its cause is economic
       such as having insufficient demand for a certain type or use of product
       that the subject property was designed to provide, increased costs
       associated with governmental regulations (good example is ADA
       requirements), changing technology, negative conditions such as high
       interest rates, unaffordable financing, or economic recessions. The
       preceding detailed that the site's proposed use or the 40 million gallon
       ethanol plant substantially represents its highest and best use. The use
       was deemed to be financially feasible and, if operated and managed at its
       capacity, should be maximally productive. For these reasons, no
       measurable external obsolescence will be noted.

             As no depreciation is observed, the subject site's previously
       concluded market value is added to the subject improvement's replacement
       cost resulting in an indication of the subject

M.     INCOME CAPITALIZATION APPROACH

             The market value developed by the Income Capitalization Approach is
       the estimated present worth of future benefits of property ownership,
       commonly referred to as NET INCOME, defined as:

             ...INCOME REMAINING AFTER ALL OPERATING EXPENSES ARE DEDUCTED FROM
             EFFECTIVE GROSS INCOME, BUT BEFORE MORTGAGE DEBT SERVICE AND BOOK
             DEPRECIATION ARE DEDUCTED; MAY BE CALCULATED BEFORE OR AFTER
             DEDUCTING REPLACEMENT RESERVES.
             (Appraisal Institute, The Dictionary of Real Estate Appraisal,
             Third Edition; 243)

       Net income or NET OPERATING INCOME is generated by a property, normally
       in the form of rent but, in some instances, in the form of income
       generated by a business operation (motels, truck stops, restaurants,
       nursing homes, grain elevators, etc.) Though not specifically stated in
       the definition, the term net operating income or net income is also
       presumed to be income before personal or corporate income taxes. Market
       participants engaged in the purchase or sale of income-producing
       properties anticipate a property's ability to generate net income which,
       in turn, can be converted into an indication of a property's value.

             The steps normally used in the Income Capitalization Approach are:

       1.    ESTIMATE THE GROSS POTENTIAL INCOME OF THE SUBJECT PROPERTY BASED
             ON MARKET RENT AND/OR BASED ON THE PROPERTY'S ABILITY TO GENERATE
             NET INCOME FROM ITS BUSINESS OPERATION. (ACTUAL CONTRACTUAL RENT
             MAY OR MAY NOT BE MARKET RENT.)

       2.    ESTIMATE AND DEDUCT A VACANCY/COLLECTION LOSS ALLOWANCE TO DERIVE
             EFFECTIVE GROSS INCOME.

       3.    ESTIMATE AND DEDUCT EXPENSES OF OPERATION TO DERIVE NET OPERATING
             INCOME (NOI) PRIOR TO SATISFYING DEBT SERVICE, PERSONAL INCOME
             TAXES, OR DEPRECIATION.

       4.    SELECT AN APPROPRIATE CAPITALIZATION METHOD OR TECHNIQUE TO CONVERT
             THE NET OPERATING INCOME INTO AN ESTIMATE OF VALUE.

             The first step in the Income Capitalization Approach is estimating
       the subject's net operating income derived from (1) actual contractual
       rent if a property is leased at or near market, (2) the business
       operation within a property, if applicable, and/or (3) an estimation of
       market rent if owner occupied. The completed subject property will be
       entirely owner occupied/operated. Thus, no actual or contractual rent is
       available. Rather, its net operating income will be generated from the
       plant's business operation. (The terms "net income" and "net operating
       income" are interchangeable and will be used as such throughout the
       following appraisal report.)

<Page>

                                                                              71

             Developing an indication of the subject property's going concern
       market value on the basis of its on-premise BUSINESS OPERATION requires,
       at a minimum, REASONABLE management skills. As such, a processing plant
       involves not only the real estate (buildings and site improvements) but
       also many business elements generally not part of income producing
       properties. These elements include furniture, fixtures, and equipment
       (FF&E), specialized and highly trained labor and management, and possibly
       inventories, working capital, and other intangible business assets.
       Additionally, this particular property type will require certain
       expenditures be made to insure continuation of the business such as
       marketing and sales expense, replacement allowances, and even pre-opening
       operating expenses. Therefore, a processing plant's market value extends
       beyond simply the real estate to include the "going concern" value
       concept, again, defined as:

             "THE VALUE CREATED BY A PROVEN PROPERTY OPERATION; CONSIDERED AS A
             SEPARATE ENTITY TO BE VALUED WITH A SPECIFIC BUSINESS
             ESTABLISHMENT." (Appraisal Institute, DICTIONARY OF REAL ESTATE
             APPRAISAL, THIRD EDITION; 160)

             This particular ethanol fuel plant's net income will be derived
       through sales of refined ethanol fuel and distillers dried grains with
       solubles (DDGS) less operating expenses before recognition of
       depreciation, mortgage interest, amortization expenses, and income taxes.
       Normally, a processing plant's historical operating statements would be
       analyzed to determine if they are reflective of the market. In this
       particular assignment, the subject property involves a proposed ethanol
       fuel plant facility and, therefore, no historical operating information
       is available. The Income Approach must then be based on an analysis of
       the owner/borrower projections and, if possible, correlated to direct or
       even indirect market evidence.

             A complete "Business Plan" was developed by Broin & Associates,
       Inc. As has been detailed, Broin & Associates is a well known and
       respected expert in the ethanol industry. Their income and expense
       projections are based on seventeen years of experience in the ethanol
       industry to include the actual design, construction, and operation of
       comparable ethanol plants located throughout this region. For this
       reason, considerable emphasis will be placed on the business plan as
       developed by Broin & Associates. A complete copy of the Business Plan has
       not been included in

<Page>

                                                                              72

       this report as the most significant parts have been copied and
       incorporated by direct or indirect reference. A complete copy has been
       retained on file.

             The following sixteen pages were taken from the "Northern Growers
       Cooperative Ethanol Plant Business Plan" prepared in September of 2000.
       The first several pages detail the market background for ethanol, DDGS,
       and corn. Income and expense projections or "profitability projections"
       are then presented in three scenarios or (1) average case, (2) best case,
       (3) worst case. Following these projections, these three scenarios have
       been combined on one page by the undersigned as to provide for ease of
       comparison. The combined/comparative profitability projections have been
       corrected in that an error was made in the computation of the income
       generated by DDGS. In the worst case scenario, a price of ***/ton was
       used, whereas, it should have been ***/ton. Conversely, ***/ton for
       DDGS was used in the best case scenario when it should have been
       ***/ton. Therefore, the changes in the appropriate areas were "penciled
       in" on the combined or comparative statement. The last four pages are the
       owner/borrower's five year projections using the "average case" scenario
       for the first year and projecting income and expense changes over the
       next four years. Further detailed discussion concerning these entire
       projections will follow. These projections are preceded by significant
       assumptions and followed by supplementary information.

       V.    MARKET EXPLANATION

       A.    ETHANOL

             The target truck marketing area for the ethanol produced at the
       proposed facility would include all the state of South Dakota, as well as
       markets in Minnesota and Northwest Iowa. Markets in Sioux Falls,
       Mitchell, Watertown and Wolsey would be primary targets for the facility,
       along with markets in Milford, LeMars, Rock Rapids and Sioux City, Iowa,
       and markets in Marshall, Alexandria, Mankato, Minneapolis and St. Paul,
       Minnesota. An ethanol facility located in Eastern South Dakota will have
       a definite freight advantage over several out-of-state companies
       currently shipping ethanol into the Twin Cities, Northwestern Minnesota
       and Canada.

             Due to the size of the facility, approximately 2/3 of the ethanol
       would be marketed by rail. The target rail markets for the facility would
       include the West, the Pacific Northwest, the Southern and Southwest
       markets, as well as potential new markets on the East Coast due to MTBE
       phase outs. The phase out of MTBE in California could create a market
       capable of consuming a large percentage of the rail traffic from the
       Northern Growers Cooperative facility.

             Should there be a price advantage shipping to other cities or
       states, the ethanol plant will have the ability to truck or rail product
       to any location that is deemed feasible. Ethanol Products, LLC has been
       marketing fuel ethanol in South Dakota, Nebraska, Minnesota, Illinois,
       Wisconsin, South Dakota, and several Western and Southern states for over
       eleven years. Ethanol Products, LLC personnel have the contacts to market
       ethanol in almost any area of the U.S.

             Selling prices for ethanol (F.O.B. the plant) have been estimated
       by Broin & Associates. In order to estimate future ethanol prices, the
       average price attained by Broin Enterprises fuel ethanol plant in
       Midwestern markets for the years 1992-1998 have been averaged. The
       average price received during this period was ***/gallon, therefore a
       slightly conservative estimate of ***/gallon has been utilized in the 5
       year financial projections.

             The effect of changes in the price of ethanol on net income of the
       project are illustrated in the average, best and worst case profitability
       scenarios of the financial forecasts. The comparison forecasts include
       first year interest and depreciation.

       B.    DISTILLERS DRIED GRAINS

             The main co-product of the ethanol production process is Distillers
       Dried Grains with Solubles (DDGS). DDGS is a high protein, high energy
       feed supplement primarily marketed to the dairy and beef industry. Recent
       research shows new potential in the swine industry. Many poultry rations
       include DDGS. DDGS is a very popular feed supplement, and a very saleable
       product.

             Selling prices (F.O.B. the plant) for financial forecast purposes
       have been estimated by Broin & Associates. In order to estimate future
       DDGS prices, the average

<Page>

                                                                              74

       price attained by Broin Enterprises fuel ethanol plant in nationwide
       markets for the years 1992-1999 have been averaged. The average price
       received during this period was ***/ton. For financial forecast
       purposes, a slightly conservative estimate of ***/ton has been utilized.

             The effect of changes in the price of DDGS on the net income of the
       project are illustrated in the average, best and worst case profitability
       scenarios of the financial forecasts.

       C.    CORN PURCHASING

             The location of the ethanol plant facility, in Grant County, South
       Dakota, allows availability of corn at acceptable basis levels. Northern
       Growers Cooperative members will deliver up to 12 million bushels of corn
       required by the plant. Northern Growers Cooperative will be paid an
       average of market prices at surrounding elevators plus freight from the
       point of origin. Delivery periods will be established, and delivery of
       corn by members will be rotated in each delivery period. The price paid
       to members at the time of delivery will be determined by management
       representatives at the beginning of each marketing period. At the end of
       each delivery period, an additional payment will be made correcting the
       price to equal the actual average of surrounding elevators during the
       delivery period plus freight from the members point of origin.

             The additional bushels required to operate the facility will be
       purchased on the open market at competitive prices. It is anticipated
       that 20-40% of this corn may be purchased from elevators during the first
       1-2 years of operation, or until a substantial customer base is
       established.

             Grant County, South Dakota produces and exports a tremendous
       quantity of corn. The basis between the Chicago Board of Trade and local
       corn prices is one of the most desirable in the country, averaging as
       wide as $.60/bushel at harvest. The accompanying statistics show the
       amount of corn grown in the Northeastern area of South Dakota (see
       Exhibit J).

             Purchase price for corn (F.O.B. the plant) has been estimated by
       Broin & Associates. In order to estimate this price, 10 year historical
       cash prices from the local elevators in the area were analyzed. The
       average on-farm corn price from 1988-1999 was $2.26/bushel. Based on this
       average, a slightly conservative estimate of $2.30/bushel has been used
       in the average case profitability scenario and the 5 year projected
       financials.

             The effect of changes in the price of corn on the net income of the
       project are illustrated in the average, best and worst case profitability
       scenarios of the financial forecasts.

                    SUMMARY OF SIGNIFICANT FINANCIAL FORECAST
                                   ASSUMPTIONS

             This financial forecast is Broin Management, LLC's estimate of the
       most probable results of operations, cash flow, and allocations of income
       (loss) for the forecast period. Accordingly, the forecast reflects
       management's judgment based on historical and present circumstances of
       the most likely set of conditions and its most likely course of action.

             The assumptions disclosed herein are those which management
       believes are significant to the financial forecast or otherwise related
       to key factors upon which the financial results of the Company depend.

             For the purpose of formulating the Financial Statements for this
       Financial Plan, several assumptions have been made, including but not
       limited to the following:

                  1) It is assumed that debt repayment will be the equivalent
       often equal principal payments, with interest on remaining principal paid
       annually.

                  2) Although no one can predict the future of commodity and
       fuel prices, the Financial Statements begin with an Average Case Scenario
       based on conservative estimates relating to historical pricing and
       operational data. The Five Year Proforma Financials are based on the
       Average Case Annual Cash Flow Statements.

                  3) Again, although no one can predict the future of commodity
       and fuel prices, the Best Case and Worst Case Annual Cash Flow Statements
       attempt to simulate how changes in the prices of corn and ethanol can
       impact plant profitability.

                         Financial Forecast Assumptions

             For the purpose of formulating the Financial Statements for this
       Financial Plan, several assumptions have been made, including but not
       limited to the following:

       (1)   It is assumed that debt principal repayment will be as follows:

           Primary Debt            Term            Rate              Amount

</Table>

       (2) Although no one can predict the future of commodity and fuel prices,
       the Financial Statements begin with an Average Case Scenario based on
       historical pricing and operational data. The Five Year Proforma
       financials arc based on the Average Case Annual Cash Flow Statements.

       (3) Again, although no one can predict the future of commodity and fuel
       prices, the Best Case and Worst Case Annual Cash Flow Statements attempt
       to simulate how changes in the prices of corn and ethanol can impact
       plant profitability.

                                                                              89

       The completed ethanol plant will generate revenues from two primary
sources plus a cash incentive provided by the state of South Dakota. The basis
for projecting these revenue sources is summarized as follows:

       1.    Ethanol Fuel: The plant is being designed as a 40 million gallon
             facility. The projections were based on the assumption that the
             plant would generate 4,808 gallons per hour with an average of 160
             hours per week, assuming 52 weeks per year. Thus, total ethanol
             capacity is computed as: 4,808 gal./hr. X 160 hrs./week X 52 weeks
             = 40,002,560 gallons. The processed ethanol would then be sold in
             the open market. The previous highest and best use discussion has
             concluded that a definite market has existed for ethanol fuel and,
             from all indications, this market will continue. According to Broin
             Enterprises, the average price received for processed ethanol from
             1992 through 1998 was */gallon. The worst case scenario used a
             market price of */gallon, the average case used */gallon,
             and the best case used */gallon. As an example, the average
             case scenario indicates total ethanol fuel sales computed as:
             40,002,560 gallons X */gallon = *. In all three scenarios, it was
             assumed that a market would exist for all 40 million gallons of
             processed ethanol fuel. Evidently, a sufficient market will exist
             to sell the entire capacity as no evidence was provided to indicate
             an over supply. Also, many of the plants that were designed,
             constructed, and managed by Broin and Associates have achieved
             production capacities exceeding those originally planned.

       2.    Distillers Dried Grains with Solubles (DDGS): The second largest
             revenue source will be through the sales of DDGS. DDGS is a high
             protein, high energy feed supplement marketed primarily to the
             cattle industry. A definite market also exists for this by-product.
             The worst case scenario used a price of */ton, the average case
             scenario used a price of */ton, and the best case scenario used
             a price of */ton. The average price received for this product
             from 1992 through 1999 has approximated */ton. As earlier
             detailed, about 17-18 pounds of DDGS are generated from one bushel
             of corn. Thus, the DDGS sales in the average case scenario was
             computed as follows: (14,286,629 bushels of corn/year X 17
             lb./bushel) / 2,000/ton X */ton = *.

       3.    State Incentive Payment: Page 7 of the Business Plan states that
             "THE STATE OF SOUTH DAKOTA PROVIDES A PRODUCTION INCENTIVE OF
             TWENTY (20) CENTS PER GALLON UP TO A MAXIMUM OF $1 MILLION PER
             YEAR. A PLANT IS ELIGIBLE TO RECEIVE A MAXIMUM OF $10 MILLION."
             This basic incentive plan was confirmed by Ms. Joan Serfling of the
             South Dakota Department of Revenue (605-773-5124). However, the
             incentive is not guaranteed as the funds available from the Capital
             Construction Fund for ethanol development are generated by
             statewide tank inspection fees of $.02/gallon of gasoline sold plus
             year end sources from interest on the fund and even from some
             on-line lottery capital. The amount available for ethanol
             development will undoubtedly become somewhat diluted as more plants
             are developed and/or monies from the Capital Construction Fund will
             not meet prior year balances, especially since the tank inspection
             fees are showing a downward trend in recent months. Thus, it is
             somewhat speculative to anticipate receiving the maximum of $1
             million per year through the state incentive payment program. Based
             on the preceding, the income from the state incentive plant will be
             reduced from $1 million annually to $500,000 annually for ten
             years. At the end of ten years, the annual income will be reduced
             by $500,000 but this loss of revenue should be offset by revenue
             increases resulting from increased plant production and/or
             increased revenues from the sale of ethanol fuel and DDGS.

             The revenue forecasts with the exception of the state cash
       incentive are reasonable in light of the current market for processed
       ethanol fuel and DDGS. Most market participants would

<Page>

                                                                              90

       undoubtedly utilize revenues generated from the average case scenario as
       it tends to be more representative of the overall ethanol market knowing
       that fluctuations can and will occur. For the purpose of this analysis,
       the first year stabilized revenues, as detailed in the average case
       scenario but reducing the state cash incentive to $500,000, will be
       utilized.

             The next step in the Income Approach is estimating operating
       expenses that are deducted from the estimated potential revenue,
       resulting in net operating income. The total operating expenses are
       typically based on one or a combination of several sources to include:

             1.   The subject property's actual historical and/or operating
                  expenses;
             2.   Estimations based on alternate market sources;
             3.   Overall expense ratios extracted from other similar property
                  types.

       In this particular appraisal, only the owner/borrower provided
       projections and some indirect market evidence is available in which to
       analyze projected expenses.

             Reference to the previous "Combined/Comparative Profitability
       Projections" chart details all expenses. Most listed expenses are
       appropriate to the plant's operation, were based on observations noted
       within other plants currently owned and/or managed by Broin & Associates,
       and, as was the case in the total revenue projections, the average case
       scenario expenses tend to be more appropriate. However, several expenses
       require some further detail or:

       1.    Corn Expense: The largest single expenditure is the purchase of the
             raw product or corn. Specifically, this expense amounts to about
             40%-71% of total revenue, depending on which scenario is selected.
             It amounts to 53% of the total revenue in the average case
             scenario. Page 9 of the Business Plan details the rationale behind
             the corn expense. First and foremost, a sufficient amount of corn
             is grown within the region to supply the plant. As earlier
             detailed, Grant County has produced an average of about 7.2 million
             bushels of corn over the last five years (1996-2000). Thus, Grant
             County alone produces about half the corn needed to operate this
             plant. Combining the corn production in nearby counties, an
             adequate corn supply will exist. The Business Plan then details
             that "THE AVERAGE ON-FARM CORN PRICE FROM 1988-1999 WAS
             $2.26/BUSHEL." The adjacent USDA-South Dakota Agricultural
             Statistics Service details that the average prices received by
             farmers for corn for the same time frame was $2.15/bushel. Thus,
             using a corn expense of $2.30/bushel in an average case scenario is
             deemed reasonable.

       2.    Utilities: Combined, the utility costs will be the second largest
             plant expenditure at slightly more than $5.9 million in the average
             case scenario or 9.6% of total projected revenues. It can only be
             assumed that these collective expenditures have been reasonably
             projected, again based on past operating histories in other plants
             owned and managed by Broin & Associates. However, it is significant
             to note that the boiler fuel expense or the cost of natural gas has
             been subject to substantial fluctuations over recent years.

                                                                              91

       3.    Maintenance and Repairs: This expenditure is attributable to
             everyday maintenance and does not include capital expenditures or
             possibly replacement allowances. The expense appears reasonable.

       4.    Replacement Allowance: No allowance has been made for periodic
             replacement of furniture, fixtures, and equipment and major
             building components as they are essential to maintain the quality,
             image, and income of an ethanol fuel plant. Therefore, a possible
             REPLACEMENT ALLOWANCE may have to be noted; it is defined as:

                  "AN ALLOWANCE THAT PROVIDES FOR THE PERIODIC REPLACEMENT OF
                  BUILDING COMPONENTS THAT WEAR OUT MORE RAPIDLY THAN THE
                  BUILDING ITSELF AND MUST BE REPLACED DURING THE BUILDING'S
                  ECONOMIC LIFE."
                  (Appraisal Institute, DICTIONARY OF REAL ESTATE APPRAISAL,
                  THIRD EDITION; 303)

             Estimating or projecting an appropriate amount for a replacement
             allowance is difficult as many of the building and equipment
             components will deteriorate at substantially different rates and
             precisely allocating costs to the separate building and equipment
             components is difficult. Reference to the previous owner/borrower
             provided cost summary indicates that the non-real property items or
             the furniture, fixtures, and equipment will amount to about $19
             million of the total cost ($48,800,000) if none of the indirect or
             soft costs are allocated. (See adjacent page.) Assuming that the
             non-real property items have an AVERAGE life of fifteen years,
             about $1,267,000/year would be needed to replace the $19 million
             ($19 million / 15 years). If the replacement allowance funds were
             invested and achieved a return of about 5%-6%, about $1 million
             annually would still need to be placed into reserves to replace the
             plant's equipment if a fifteen year life were appropriate. It is
             entirely possible that the equipment will have a longer average
             life but some of the building components will also need periodical
             replacement. Thus, it is conceivable that a replacement allowance
             of $1 million annually should be anticipated even though an annual
             "maintenance/repairs" expenditure of $800,000 is noted.

       5.    Management and Marketing Expenses: These two components will be
             contracted to affiliates of Broin Enterprises. Specifically, a
             "Contract for Future Services" has already been executed between
             Northern Growers Cooperative, now known as Northern Lights Ethanol,
             LLC, and Broin & Associates. (A complete copy of the contract is
             part of the previously referenced Business Plan.) Per the Business
             Plan, "THE COST OF THE MANAGEMENT SERVICES WILL BE $250,000 PER
             YEAR BASE FEE PLUS AN ANNUAL BONUS TOTALING 5% OF NET PROFITS. THE
             INITIAL TERM IS THREE (3) YEARS." The worst case scenario shows a
             minimum management expense of $250,000 as there are no net profits,
             whereas, the other two scenarios have net profits added to the
             $250,000 base. Evidently, this management fee is consistent with
             the market as it has been secured by Broin & Associates in the
             management of numerous other ethanol plants. The marketing expense
             will be fees paid to market the distilled ethanol fuel and the
             DDGS. Again, this marketing expense is consistent with those
             charged in other operating ethanol plants.

       6.    The last two listed expenses or depreciation and interest are not
             applicable to the valuation process. These two expenses need to be
             deducted from the total.

             With the exception of the last two expenditures or depreciation and
       interest, all other listed expenses are appropriate to the plant, were
       based on observations noted within other plants currently owned and
       managed by Broin and Associates, and, again, the expenses listed in the
       average case scenario would tend to be more appropriate. Ideally, these
       expenditures should also be

<Page>

                                                                              92

       compared to direct or indirect market evidence as to ascertain their
       appropriateness and/or reasonableness. However, this information was not
       specifically provided, though Mr. Larry Ward of Broin & Associates made
       the assurance that these expenditures are entirely appropriate.
       Evidently, the stockholders of Northern Lights Ethanol, LLC had verified
       the expenses as being appropriate in their due diligence in determining
       the project's feasibility..

             Again, the expenses reported in the average case scenario are
       deemed to be most applicable. All expenses are appropriate with the
       exception that the depreciation and interest expense need to be deducted
       and a replacement allowance of $1 million needs to be added. Also, the
       $500,000 state cash incentive has to be noted. Based on the preceding,
       the average case scenario revenues and expenses are adjusted as follows:

                                                                say,   $ 11,500,000
</Table>

             This stabilized net income of $11.5 million is based on the
       "average case" scenario as it relates to projected income and expense. It
       is important to reference page 13 of the Business Plan as it summarizes
       the significant financial forecast assumptions. To paraphrase, the
       projections were based on the most appropriate data available plus the
       "MANAGEMENT'S JUDGEMENT BASED ON HISTORICAL AND PRESENT CIRCUMSTANCES OF
       THE MOST LIKELY SET OF CONDITIONS AND ITS MOST LIKELY COURSE OF ACTION."
       Simply, considerable confidence must be placed in the projections made by
       Broin and Associates as they are known experts in the industry. Based on
       the available information, the $11.5 million will be used as the first
       year stabilized net income.

                                                                              93

             A five year pro forma was also prepared or the last four pages of
       the previously copied Business Plan excerpt. The five year projection was
       based on the assumption that annual production would increase from about
       40 million gallons in the first year to * gallons in the fifth year or an
       increase of * over the total five years or about * annually. The
       unadjusted net profit is projected to increase about * over the five
       years or about * annually. The question now arises as to whether a single
       year net income conclusion or a series of probable net income increases
       should be utilized. The answer to this question then determines which of
       the two most common methods of capitalizing net income into a going
       concern market value would be utilized or

       DIRECT CAPITALIZATION and YIELD CAPITALIZATION, defined as follows:

       1.    DIRECT CAPITALIZATION: A METHOD USED TO CONVERT AN ESTIMATE OF A
             SINGLE YEAR'S INCOME EXPECTANCY INTO AN INDICATION OF VALUE IN ONE
             DIRECT STEP--EITHER BY DIVIDING THE NET INCOME ESTIMATE BY AN
             APPROPRIATE INCOME RATE OR BY MULTIPLYING THE INCOME ESTIMATE BY AN
             APPROPRIATE FACTOR. (Appraisal Institute, DICTIONARY OF REAL ESTATE
             APPRAISAL, THIRD EDITION; 100)

       2.    YIELD CAPITALIZATION: THE CAPITALIZATION METHOD USED TO CONVERT
             FUTURE BENEFITS INTO PRESENT VALUE BY DISCOUNTING EACH FUTURE
             BENEFIT AT AN APPROPRIATE YIELD RATE OR BY DEVELOPING AN OVERALL
             RATE THAT EXPLICITLY REFLECTS THE INVESTMENT'S INCOME PATTERN,
             VALUE CHANGE, AND YIELD RATE. (Appraisal Institute, DICTIONARY OF
             REAL ESTATE APPRAISAL, Third Edition; 398)

             Direct Capitalization is direct, easily understood, and is
       frequently used by most area buyers in the purchase of most property
       types. The net operating income (NOI) is simply divided by an overall
       rate (R(O)) resulting in a value indication (V). The net operating income
       (NOI) expectancy is frequently the anticipated income for the forthcoming
       income period. The NOI is then divided by an overall rate (OAR or R)
       which represents (1) the relationship between income and value observed
       in the market and/or (2) the annual rate of return necessary to attract
       investment capital. Direct Capitalization is normally applicable to
       stable levels of net operating income and is used by many buyers
       primarily concerned with value predicated on present income or income
       projected into the very near future. The major disadvantage of direct
       capitalization is that it does not recognize changing levels of income.

             Income changes in an ethanol fuel plant are not scheduled but,
       rather, they are subject to change in commodity prices, climatic
       conditions, management, etc. If a strong market exists for the property's
       products and good management is in place, all indications are that
       revenues should

<Page>

                                                                              94

       increase and, subsequently, net operating income should also increase.
       However, the reverse would be true if these same market conditions were
       to reverse. Therefore, the utilization of Yield Capitalization requires
       that ACCURATE estimations as to these changing market conditions
       anticipated over the course of ownership be made, an almost impossible
       task.

             Typically, most buyers of this particular property type would base
       their purchasing decision on actual income performance from present or
       immediate past operation with only minimal consideration given to
       forecasted income. Increased income beyond the date of sale generally
       results from new ownership and the operation from the buyer's
       perspective. Therefore, most weight would be afforded to the plant's
       "present" income producing capability. For these reasons, Yield
       Capitalization has the least reliability in this analysis. However, some
       weight will be afforded to the observation that a potential does exist
       for increased income when applying Direct Capitalization in developing an
       opinion of the subject property's going concern market value opinion.

             Again, the going concern market value (V) developed through
       application of Direct Capitalization is computed by dividing the net
       operating income (NOI) by an overall rate (OAR or R). An overall rate is
       an income rate as it expresses the relationship between one year's income
       and the corresponding capital value of a property. It may be more than,
       less than, or equal to the expected yield on the capital invested
       (normally the down payment when financing is involved), depending on
       projected changes in income and future value. This rate of return
       represents the annual rate of return necessary to attract investment
       capital for a particular property type. As paraphrased from THE APPRAISAL
       OF REAL ESTATE, Twelfth Edition as published by the Appraisal Institute
       on page 491, the rate of return is influenced by many factors including
       the degree of apparent risk, market expectations regarding future
       inflation, the prospective rates of return for alternative investments,
       the rates of return earned by comparable properties in the past, the
       availability of debt financing, and the prevailing tax law. Generally,
       higher overall rates are associated with less desirable properties and
       more attractive properties are associated with lower overall rates.

             Many accepted methods of deriving an overall rate are available but
       the two that will be utilized in this report are: (1) derivation from
       direct or indirect market evidence and (2) Band of Investment utilizing
       mortgage and equity components. The first method or deriving overall
       rates from

<Page>

                                                                              95

       direct market evidence results from locating "similar use" property sales
       and dividing their respective net operating incomes by the purchase
       price. Again, no similar property sales were available in this particular
       assignment. An alternative source of direct market evidence is made by
       referring to the adjacent REGIONAL MARKET INDICATORS SAMPLING chart. It
       indicates overall rates ranging from about 11%-19% for these property
       types located mostly in North and South Dakota. None of the property
       types are similar to the subject but, yet, the motel and convenience
       store categories reflect overall rates inclusive of the operation of an
       on-premise business. These two property types indicate overall rates
       ranging from about 12% to nearly 19%. The subject property's anticipated
       overall rate would be at least comparable to, if not in excess of even
       the highest overall rate of 19% as the perception of risk in operating an
       ethanol fuel plant is much greater than that found in motels or
       convenience stores.

             The second technique that will be used in the derivation of an
       overall capitalization rate is the "Band of Investment" analysis using
       mortgage and equity components. In this method, an overall capitalization
       rate (R(O)) is built up by mortgage and equity components. This method is
       based on the premise that investments are financed with the equity
       investor seeking to obtain the best available loan or mortgage terms in
       order to maximize the potential benefits of leverage. The analysis of an
       overall rate by the Band of Investment method develops a weighted average
       between the return on investment that is required to cover the mortgage
       portion and the return on the investment that is required to cover the
       equity portion.

             The Band of Investment method is comprised of mortgage and equity
       components, specifically, the mortgage constant derived from an interest
       rate, the equity dividend rate, and mortgage and equity positions. The
       mortgage constant for the selected mortgage interest rate is the
       component for the mortgage return; and the cash on cash return or
       spendable income, more commonly referred to as the equity dividend rate,
       is the latter component. The weights are percentages of the total
       investment represented by the initial equity investment. Therefore, the
       utilization of the Band of Investment method in developing a
       capitalization or overall rate requires the proper selection of a
       mortgage interest constant, loan-to-value ratio, and an equity dividend
       rate.

             The financial projections made in the borrower's aforementioned
       Business Plan had assumed debt repayment based on an interest rate of
       9.5%, an amortization period of ten years, and a loan-to-

<Page>

                                                                              96

       cost ratio of 60%. The client's account representative or Mr. Carl
       Johnson, U.S. Bank Sioux Falls office, indicated that mortgage interest
       rates would undoubtedly approximate 8.25%-8.75% but, yet, would still be
       amortized only over ten years and a loan-to-value ratio not to exceed
       75%. The comparatively shorter amortization period is required due to the
       considerable amount of non-real property items and business component
       within this particular property type. A representative of the local Wells
       Fargo bank also verified that the approximate terms currently quoted by
       the client would be consistent with their lending practices.

             For the purpose of this analysis, a mortgage constant will be
       computed using a loan-to-value ratio of 65%, amortized over 10 years, and
       a stabilized mortgage interest rate of 8.5%. The mortgage interest rate
       of 8.5% attempts to reflect a stabilized rate over the course of normal
       ownership and includes some provision for loan fees. At these terms,
       monthly payments are assumed. An annual mortgage constant of .1488
       results utilizing these financing terms. (The actual computation of the
       mortgage constant is made using a financial calculator but the same
       results can be obtained through the use of financial tables.) The
       mortgage constant represents the return to the mortgage component within
       the Band of Investment Analysis.

             The second component requiring analytical consideration in
       development of the overall rate by the Band of Investment is the equity
       dividend rate (EDR) or the equity capitalization rate. The EQUITY
       DIVIDEND or EQUITY CAPITALIZATION RATE is defined as:

             "AN INCOME RATE THAT REFLECTS THE RELATIONSHIP BETWEEN A
             SINGLE YEAR'S PRE-TAX CASH FLOW EXPECTANCY AND THE EQUITY
             INVESTMENT." (Source: THE APPRAISAL OF REAL ESTATE, Eleventh
             Edition, published by the Appraisal Institute.)

       This rate is many times referred to in the real estate market as the CASH
       ON CASH RETURN or CASH FLOW RATE. Like the overall capitalization rate,
       the equity dividend rate (EDR) depends on projected changes in income,
       value, and amortization of a loan. A knowledgeable investor normally
       attempts to seek a return on invested equity at least comparable to the
       cost of the mortgage (mortgage interest rate). However, it was
       historically common for investors to invest with equity dividend rates
       below the cost of the mortgage or even have negative equity dividend
       returns. The tax benefits of real estate ownership prior to 1986 and also
       the continued inflationary trends of real estate more than offset the low
       equity return rate. The present investor now realizes that the equity
       dividend rate must provide an acceptable equity return.

<Page>

                                                                              97

             Ideally, equity dividend rates should also be extracted from direct
       market evidence. Again, no direct market evidence was available in which
       to extract an equity dividend rate. Alternatively, reference is again
       made to the previously referenced REGIONAL MARKET INDICATORS SAMPLING
       chart. With the exception of one EDR of 11.4%, the balance of the data
       indicates EDRs approximating 15%-21%. An equity dividend rate even in
       excess of this range would be anticipated because of the again perceived
       greater risk inherent in the operation of an ethanol fuel plant.

             Indications of more appropriate equity dividend rates were provided
       by ConAgra's 2001 Annual Report. The adjacent page highlights ConAgra's
       financial performance plus details some of their expectations. Over the
       last six years or through fiscal 2001, ConAgra's annual average return on
       common equity was 27.2% excluding "unusual items". The overall range was
       24.3%-29.9%. The report also states that "ONE OF CONAGRA FOODS' KEY
       FINANCIAL OBJECTIVES OVER THE LONG TERM IS TO AVERAGE MORE THAN A 20%
       AFTER-TAX CASH EARNINGS RETURN ON YEAR-BEGINNING COMMON STOCKHOLDERS'
       EQUITY, AND TO EARN MORE THAN A 15% RETURN IN ANY GIVEN YEAR."
       Collectively, this agricultural industry leader is anticipating pre-tax
       equity dividend rates approximating 20%-30%.

             The anticipated equity return for a specialized ag-related industry
       is comparatively greater than that noted in more standard real estate
       investments. If ConAgra or an agricultural industry leader is
       anticipating 20%-30% OVERALL equity return, it is entirely probable that
       the subject property, as a single source specialty commodity, may have to
       anticipate an equity return approximating the upper end of this range.
       Thus, the available market data suggests that the subject property's
       anticipated equity dividend rate would approximate a range of 25% to 30%,
       especially if the property's probable value change over the course of
       ownership is considered. Specifically, the last component in the mortgage
       equity analysis to consider is the subject property's anticipated value
       change, if any, throughout the anticipated length of ownership. It stands
       to reason that, if a property is appreciating in value, the overall
       return to an investor is partially recaptured in the property
       appreciation. If a property is depreciating in value, added return is
       necessary to keep a desired investment goal. In the absence of sufficient
       market support to substantiate a probable change in this property's
       value, equity dividend rates of 25% and 30% will be used as the return to
       the equity funds within the Band of Investment Analysis.

             Based on the preceding, the Band of Investment development of an
       overall rate will use a mortgage constant based on an interest rate of
       8.5% amortized over 10 years, a loan-to-value ratio of 65%, and equity
       dividend rates of 25% and 30%. The following computations apply these
       conclusions to the Band of Investment analysis, resulting in an overall
       rate range:

</Table>

             The two sources used in deriving an applicable overall rate
       resulted in the following conclusions:

                  1.  Indirect Market Evidence -        In excess of 12%-19%
                  2.  Band of Investment -              18.5%-20%

             Most consideration has to be afforded to the overall rate range
       developed by the Band of Investment analysis. Specifically, the indirect
       market evidence simply does not have true similarity. The Band of
       Investment indicated an overall rate range of about 18.5% to 20%. An
       overall rate at or near the upper end of this range would be anticipated
       as to reflect that the net income is generated by a highly specialized
       business operation, the comparatively higher non-liquidity in this type
       of investment, the considerable dependence on management, the uncertainty
       in the farm commodity prices, etc. For the purpose of this analysis, an
       overall rate of 20.0% is selected and applied to the subject property's
       estimated net income of $11,500,000 as follows:

             1.  Estimated Net Income                      $    11,500,000

             Indication by Income Capitalization Approach  $    57,500,000

             (As a footnote, the previous conversion of the ground rent into a
             market value indication used overall rates of 6% and 9%. The
             overall rate applicable to ONLY the site would be far less than the
             property's 20% overall rate as the 20% overall rate includes a
             return to the site, the improvements, and the non-real property
             components. For this reason, the selected land overall rates of 6%
             and 9.0% were deemed applicable.)

                                                                              99

N.     RECONCILIATION

       The final step in the appraisal process is termed RECONCILIATION; it is
       defined as:

       "THE LAST PHASE OF ANY VALUATION ASSIGNMENT IN WHICH TWO OR MORE VALUE
       INDICATIONS DERIVED FROM MARKET DATA ARE RESOLVED INTO A FINAL VALUE
       ESTIMATE, WHICH MAY BE EITHER A FINAL RANGE OF VALUE OR A SINGLE POINT
       ESTIMATE." (The Appraisal Institute, Dictionary of Real Estate Appraisal,
       Third Edition; 296)

             The primary appraisal objective was to formulate an opinion of the
       subject property's PROSPECTIVE AS-COMPLETE LEASEHOLD GOING CONCERN MARKET
       VALUE, as of November 1, 2002, or the date the proposed subject
       improvements are scheduled to be completed. The most appropriate
       appraisal process available to develop this value opinion is to first
       develop an opinion of the subject property's as-complete going concern
       market value assuming FEE SIMPLE ownership existed. The entire previous
       valuation analysis addresses the subject property's fee simple ownership
       interest or an ownership interest that first disregards the underlying
       land lease. Application of the two applicable valuation techniques used
       in addressing the subject property's going concern market value resulted
       in the following:

<Table>
                                                          
                  Cost Approach                              $ 48,825,000
                  Income Capitalization Approach             $ 57,500,000
</Table>

             Theoretically, these two valuation techniques used in developing
       the going concern market value should result in identical value
       conclusions. As a practical matter, the results are virtually never
       identical since the marketplace does not operate in a perfect
       environment. Reconciliation of the value indications is, therefore,
       necessary in order to formulate the subject property's final going
       concern market value conclusion.

             In this particular assignment, considerable weight is afforded to
       the market value indication developed through the Cost Approach. When
       complete, the subject improvements will be new and the proposed use or
       that of an ethanol fuel plant was found to substantially represent the
       site's highest and best use. As such, sufficient market should exist to
       substantiate the majority of the replacement cost due to the basic
       underlying principal of substitution. To repeat, a prudent buyer would
       pay no more for a property than the cost to acquire a similar site and
       construct improvements of equivalent desirability and utility without
       undue delay. As detailed, the completed

                                                                             100

       improvements will be state-of-the-art and, if placed into the open market
       when complete, the property would have exceptionally good
       characteristics. The market value developed through application of the
       Cost Approach has good reliability because of the underlying support as
       it relates to the predominant component or that of the improvement's
       replacement cost. Furthermore, the application of the Income
       Capitalization Approach definitely supported the replacement cost.

             The completed subject property's primary market appeal will be
       created by its income characteristics; a factor given primary concern in
       the marketability of a profitable ethanol fuel plant. If placed into the
       open market, it is possible that most buyers would consider ONLY the
       property's income producing characteristics. Thus, the subject property's
       revenue and expense potential is a vital component in this valuation
       analysis. For these reasons, considerable weight is also given to the
       going concern market value as indicated by the Income Capitalization
       Approach.

             The two major components within this valuation technique or (1) the
       net operating income estimate and (2) the selected overall capitalization
       rate required a careful analysis of the subject property's anticipated
       business operation and the resulting marketplace anticipations. The net
       operating income was based entirely on projections made by the
       owner/borrower through Broin & Associates. The net income resulted from
       what was considered to be an "average case" scenario but most all
       components had reasonably good market support. The resulting net
       operating income was then capitalized into a going concern market value
       using direct capitalization or through use of an overall rate. The
       overall rate had to consider that the completed plant has the potential
       for increased future revenues but, yet, the associated risk with
       purchasing this property type also had to be incorporated. Collectively,
       the resulting going concern market value indication developed by the
       Income Capitalization Approach was deemed reliable though it exceeded the
       indication through application of the Cost Approach.

             The final element of consideration required for a properly
       developed going concern market value relates to REASONABLE EXPOSURE TIME,
       defined as:

<Page>

                                                                             101

             "THE ESTIMATED LENGTH OF TIME THE PROPERTY INTEREST BEING APPRAISED
             WOULD HAVE BEEN OFFERED ON THE MARKET PRIOR TO THE HYPOTHETICAL
             CONSUMMATION OF A SALE AT MARKET VALUE ON THE EFFECTIVE DATE OF THE
             APPRAISAL; A RETROSPECTIVE OPINION BASED UPON AN ANALYSIS OF PAST
             EVENTS ASSUMING A COMPETITIVE AND OPEN MARKET.

             (Source: Statement 6 of the UNIFORM STANDARDS OF PROFESSIONAL
             APPRAISAL PRACTICE (USPAP), adopted on September 16, 1992.)

             The fact that exposure time is always presumed to occur PRIOR to
       the appraisal's effective date is substantiated by related facts in the
       appraisal process or supply and demand conditions, use of current cost
       information, the analysis of historical sales (the sales sold AFTER
       reasonable exposure and after completion of negotiations between the
       seller and buyer), and/or the analysis of future income expectancy.
       Exposure time is different for various property types and under various
       market conditions. This concept of reasonable exposure time encompasses
       not only adequate, sufficient, and reasonable TIME but also adequate,
       sufficient, and reasonable EFFORT. Likewise, the reasonable exposure
       period is a function of price, time, and use; it is not an isolated
       opinion of time alone. (Much of the previous paragraph was paraphrased
       from page 83 of the USPAP 2001 Edition relating to Statement 6.)
       Therefore, several other elements to the concept of reasonable exposure
       time are implied in the definition or:

             1.   THE PROPERTY IS ACTIVELY EXPOSED AND AGGRESSIVELY MARKETED TO
                  POTENTIAL PURCHASERS THROUGH MARKETING CHANNELS COMMONLY USED
                  BY BUYERS AND SELLERS OF SIMILAR TYPE PROPERTIES.

             2.   THE PROPERTY IS OFFERED AT A PRICE REFLECTING THE MOST
                  PROBABLE MARKUP OVER MARKET VALUE USED BY SELLER OF
                  SIMILAR TYPE PROPERTIES.

             3.   A SALE IS CONSUMMATED UNDER TERMS AND CONDITIONS OF THE
                  DEFINITION OF MARKET VALUE AS USED WITHIN THIS REPORT.

                  (Appraisal Institute, THE APPRAISAL JOURNAL; "User-Friendly
                  Appraisal Reports", October 1992)

             The estimate of reasonable exposure time is normally based on one
       or more of the following: (1) published statistical information, (2)
       information gathered through sales verification, and (3) interviews of
       market participants. In this particular assignment, only indirect market
       evidence and input provided by market participants provided some
       indication as to probable exposure time.

             The previously referenced REGIONAL MARKET INDICATORS SAMPLING chart
       indicated exposure times ranging from about two months to one year. Most
       standard property types will market within

<Page>

                                                                             102

       one year if competitively priced. This particular property type or that
       of an operating ethanol fuel plant is not a standard property type. Most
       market participants interviewed in this assignment indicated that, if
       even competitively priced, an exposure time exceeding one year would have
       to anticipated because of the limited number of available or even
       interested buyers. An exposure time of one to two years should be
       sufficient to adequately expose the property to a regional or even
       national level with every attempt made to achieve optimum value. Based on
       these market observations, a reasonable exposure time or the time needed
       to market the property preceding the appraisal's effective date is
       estimated at one-two years.

             In summary, the two valuation techniques used in developing the
       subject property's as-complete fee simple going concern market value
       resulted in a range of $48,825,000 (as developed by the Cost Approach) to
       $57,500,000 (as developed by the Income Capitalization Approach). The
       going concern market value as developed by the Income Capitalization
       Approach or $57,500,000 needs to be somewhat tempered by the realization
       that even small fluctuations in any of the commodity prices or
       expenditures could have a major impact on the property's profitability.
       In theory, the selection of an overall rate should have incorporated this
       potential risk. In reality, measuring this risk perception is difficult
       because of the simple lack of truly market supported overall rates. For
       this primary reason, most consideration is afforded to the going concern
       market value as developed by the Cost Approach. Based on this analysis
       and considering the subject property's characteristics relative to its
       particular market segment, its as-complete fee simple going concern
       market value, as of November 1, 2002, is projected to be:

                              FIFTY MILLION DOLLARS
                                  ($50,000,000)

             The as-complete going concern market value conclusion for the
       "Northern Lights Ethanol Fuel Plant" includes the contributory value of
       the (1) real property (site and improvements) AND (2) the contributory
       value of the non-real property items or furniture, fixtures, and
       equipment (FF&E), personal property, trade fixtures, and all other
       intangible items required in the complete operation of an ethanol plant.
       Again, this GOING-CONCERN VALUE, defined as "THE VALUE CREATED BY A
       PROVEN PROPERTY OPERATION; CONSIDERED AS A SEPARATE ENTITY TO BE VALUED
       WITH A SPECIFIC BUSINESS

<Page>

                                                                             103

       ESTABLISHMENT." (Appraisal Institute, DICTIONARY OF REAL ESTATE
       APPRAISAL, THIRD Edition; 160). In this particular property, a
       going-concern component will definitely exist as management will be an
       integral part of the property's future profitability, and, in its
       simplest form, the value of an ethanol fuel plant property exists only
       after the assemblage of the site, improvements, labor, equipment, and
       marketing. This assemblage creates an economically viable business that
       is expected to continue.

             Standards Rule 1-2 (e) of the UNIFORM STANDARDS OF PROFESSIONAL
       APPRAISAL PRACTICE (USPAP) states that the appraisal must "IDENTIFY AND
       CONSIDER THE EFFECT ON VALUE OF ANY PERSONAL PROPERTY, TRADE FIXTURES, OR
       OTHER INTANGIBLE ITEMS THAT ARE NOT REAL PROPERTY BUT ARE INCLUDED IN THE
       APPRAISAL". Therefore, an attempt should be made to identify the
       contributory value of all non-real property items. Accurately allocating
       the non-real property items from the concluded going concern market value
       is a controversial topic as it is difficult to determine EXACTLY at which
       point the income attributable to the business stops and the income
       attributable to the real estate begins. Even so, this allocation process
       will be addressed as to comply with USPAP.

             Actual direct market support would provide the most reliable
       indication of the contributory value of the non-real property items. The
       amount of non-real property items to include the intangibles relating to
       the completed subject property's going concern component would be
       comparatively more than most standard property types as it includes a
       significant amount of processing equipment. The adjacent page is the last
       page of the previously referenced cost summary entitled "Contract
       Schedule of Values, Project Estimate" in which the components deemed
       primarily fixtures and equipment have been highlighted. The highlighted
       items on the left column total nearly $19 million. Additionally, a large
       percentage of at least three other cost components would have some costs
       allocated to non-real property items or (1) other construction costs, (2)
       excise tax, and (3) owner's project costs. These three line items have
       simply been divided in half with the total being $5,880,396. Adding this
       amount to the total for the itemized non-real property items of
       $18,977,208 indicates a non-real property component cost estimate of
       $24,877,640 or nearly 51% of the total cost.

<Page>

                                                                             104

             Understandably, some of the equipment may be deemed permanent
       fixtures but yet the non-real property component would still be
       significant. More importantly, the amount of the total going concern
       market value attributable to an economically viable business is as
       important as the processing equipment. In the absence of more definitive
       market support, the contributory value of the completed subject
       property's non-real property items/going concern component is estimated
       at 40% of the total or $20,000,000 ($50,000,000 x 40%).

             Based on this market analysis, the following allocation of the
       subject property's concluded prospective as-complete and stabilized fee
       simple going concern market value is made:

<Table>
                                                                                     
             1.  Real Property (Site and Improvements)                                  $30,000,000 -  60.0%

             2.  Non-Real Property Items to include Going-Concern
                 (FF&E, personal property, etc.)                                         20,000,000 -  40.0%
                                                                                        -----------    ----

                 Total Concluded As-Complete
                 Going Concern Market Value                                             $50,000,000 - 100.0%
</Table>

       Again, these are value allocations. They do NOT represent individual
       market value conclusions for each component but, rather, their estimated
       contributory value to the total fee simple as-complete going concern
       market value.

                                                                             105

O.     LEASEHOLD ESTATE VALUATION

             The previous analysis developed an opinion of the subject
       property's FEE SIMPLE market value that assumed complete ownership in
       both the site and improvements. However, the owner/ borrower or Northern
       Lights Ethanol, LLC leases the underlying site. The right of use or
       interest possessed by the tenant is commonly known as LEASEHOLD INTEREST,
       defined as:

             "THE INTEREST HELD BY THE LESSEE (THE TENANT OR RENTER) THROUGH A
             LEASE CONVEYING THE RIGHTS OF USE AND OCCUPANCY FOR A STATED TERM
             UNDER CERTAIN CONDITIONS." (Appraisal Institute, DICTIONARY OF REAL
             ESTATE APPRAISAL, 3rd Edition; 204)

             Leasehold estate interest implies that, when a lease is
       transmitted, a tenant usually acquires the rights to possess the property
       (in this case, the site only) for the lease period, to sublease the
       property if desired, and/or improve the leased property under the
       restrictions specified in the lease. In return, the tenant is obligated
       to pay rent, surrender possession of the property at the termination of
       the lease, remove any improvements the lessee has modified or constructed
       if specified, and abide by the lease provisions. The property owner or
       landlord (Big Stone-Grant Industrial Development and Transportation,
       L.L.C., simply referenced as Big Stone-Grant Industrial) limited rights
       in this site will eventually be restored to fee simple ownership in the
       event that the existing land lease expires or is terminated. For the
       interim, however, the site owner's or Big Stone-Grant Industrial
       Development rights for use of the site are something less than "absolute"
       due to the presence of the site lease. As such, their encumbered
       ownership in the site is referred to as the LEASED FEE ESTATE or
       ownership, defined as:

             "AN OWNERSHIP INTEREST HELD BY A LANDLORD WITH THE RIGHT OF USE AND
             OCCUPANCY CONVEYED BY LEASE TO OTHERS. THE RIGHTS OF THE LESSOR
             (THE LEASED FEE OWNER) AND THE LEASED FEE ARE SPECIFIED BY CONTRACT
             TERMS CONTAINED WITHIN THE LEASE." (Appraisal Institute, DICTIONARY
             OF REAL ESTATE APPRAISAL, 3rd Edition; 204)

             When considered separately, the interests of "leasehold estate" and
       "leased fee estate" are each readily identified as separate property
       interests that are something less than the absolute ownership known as
       "fee simple estate". Leasehold estate and leased fee estate are
       fractional interests of the property's fee simple estate. The sum of
       these two fractional interests represents the property's complete fee
       simple estate or ownership rights or:

                          A% Leased Fee Estate (Landlord's position)
                     +    B% LEASEHOLD ESTATE  (Tenant's position)

<Page>

                                                                             106

                     =    100% Fee Simple Estate (Absolute Interest)

             Based on the previous discussion, the sum of (1) the leased fee
       estate or Big Stone-Grant Industrial Development's ownership interest in
       the underlying site plus (2) Northern Lights Ethanol's leasehold estate
       or the ownership interest in the completed improvements equals the
       property's 100% fee simple estate (previously concluded at $50,000,000).
       The balance of this discussion then needs to address the matter of
       formulating an opinion of the market value of one of the partial
       interests, deducting this value from the property's previously concluded
       fee simple market value estate or $50,000,000, and the result would be
       the market value of the remaining partial interest. In this particular
       appraisal, the previous valuation analysis has already addressed the
       estimated market value of the underlying site; it was concluded to be
       $25,000.

             A leasehold estate or the tenant's interest (Northern Lights
       Ethanol) in the underlying leased subject site is said to be marketable
       when (1) contract rent is measurably LESS than market rent and/or (2) the
       contract or lease term is of such duration that it would be economically
       feasible to assume the lease. If contract rent is less than market rent,
       a potential incentive exists for a prospective assignee to pay a sum to
       acquire the right to occupy the leased space (right to continue to lease
       the underlying site) at rent that is below prevailing market levels.
       Logically, the market value of a leasehold interest would be represented
       by the price of the contract (actual) rent plus a value enhancement
       recognized by the market. The sum of the two components cannot exceed
       market rent since a prudent tenant would not pay an amount in excess of
       market rent to occupy space if comparable space could be obtained
       elsewhere for less within a reasonable period of time (principle of
       substitution).

             Reference is made to pages 58 and 59 in which the current "Ground
       Lease Agreement" is detailed. As noted, the average annual ground rent
       throughout the 99-year lease term will approximate $4,000. At this rent,
       the tenant would be responsible for paying all expenses relating to the
       site.

             The initial thought in developing the tenant's or Northern Lights
       Ethanol's leasehold interest is simply to subtract the land lease payment
       from the net operating income and capitalize the result into a market
       value estimate. However, this methodology would apply only IF the land

<Page>

                                                                             107

       lease approximated market. The prior lease analysis had capitalized this
       average annual net rent of $4,000 into a market value estimate using
       overall rates of 6% and 9%. The resulting market value estimate of about
       $44,000 to $67,000 or $1,200 to $1,800/acre far exceeds the concluded fee
       simple market value of about $25,000 or about $683/acre. Thus, the
       underlying site is rented above what is deemed to be market levels. Even
       so, the tenant would have no marketable interest in the underlying land
       lease as the rent exceeds market but, more significantly, the
       contributory value of the site is negligible. Simply, a site having a
       contributory value of $25,000 or, even say $67,000, is insignificant when
       compared to the property's overall value conclusion of $50,000,000. For
       these reasons, the initial opinion of the leasehold estate's market value
       of the subject improvements is deemed to be comparable to the fee simple
       market value.

             The concern now relates to whether the market would discount the
       PROPERTY'S fee simple market value estimate of $50,000,000 for the market
       perception of purchasing improvements located on a leased site.
       Specifically, market perception of purchasing most standard or
       non-institutional improvements located on a leased site normally tends to
       be something more than simply deducting the site's value. This market
       observation has been confirmed numerous times over the years with
       individuals involved in the ownership, property management, and/or sale
       of income producing properties located in the upper midwest. However,
       this particular improvement type or that of a large ethanol fuel
       processing plant would appeal to more institutional type users or, in
       other words, more sophisticated users and, ultimately, more sophisticated
       or institutional buyers/investors. Land leases are not unusual in the
       institutional market, especially if the land leases are relatively
       straightforward, are long term, and the lease terms approximate market.
       In this particular instance, all these conditions exist. For these
       reasons, no measurable discount would result in attempting to market this
       leasehold interest. Based on the results of this appraisal investigation
       and analysis, the going concern market value of the as-complete subject
       improvement's leasehold estate, as of November 1, 2002, is projected to
       be:

                              FIFTY MILLION DOLLARS
                                  ($50,000,000)

                                                                             108

             III. OBJECTIVE #2-"AS-IS" LEASEHOLD MARKET VALUE ANALYSIS

A.     APPRAISAL OBJECTIVE:

             The previous appraisal objectives were based on the assumption that
       the subject improvements would be a completed 40 million gallon ethanol
       fuel plant. The client also specified that one last appraisal objective
       be provided or that of developing an opinion of the subject property's
       "as-is" fee simple going concern market value as of the appraisal
       inspection date or September 17, 2001. As previously detailed, a value
       based on the property's as-is condition "RELATES TO WHAT PHYSICALLY
       EXISTS AND IS LEGALLY PERMISSIBLE AND EXCLUDES ALL ASSUMPTIONS CONCERNING
       HYPOTHETICAL MARKET CONDITIONS...". Therefore, this last appraisal
       objective is to develop an opinion of the subject property's as-is fee
       simple going concern market value as of the appraisal inspection date or
       September 17, 2001, or that of a partially completed ethanol fuel plant.

B.     SCOPE:

             The majority of the preceding appraisal process relative to
       definitions, assumptions, appraisal's intended use, ownership rights,
       city/market and neighborhood descriptions, the site description, and
       highest and best use analysis would still be applicable. The following
       analysis will, therefore, begin with the improvement's description in
       their AS-IS condition and conclude with the development of market value.

C.     DESCRIPTION OF IMPROVEMENTS:

             In its as-is condition, approximately 25% of the project was
       complete. Briefly, the site had been graded, most underground utilities
       installed, considerable amount of poured concrete installed, some of the
       storage tanks erected, and other miscellaneous improvements completed.

                                                                             109

D.     VALUATION PROCESS:

             Ideally, an attempt should be made to assemble sales of ethanol
       plants in a similar state of completion or that as found in the subject
       property on September 17, 2001. Again, the improvements were
       approximately 25% complete. In reality, such market data simply does not
       exist. For this reason, development of the subject property's as-is
       market value can only be based only on a simple logical interpretation.

             The subject property's previously concluded market value assuming
       completion of the subject improvements was $50,000,000 with the
       underlying site having no measurable or contributory value. If the
       improvements were 25% complete, the preliminary indication of the
       improvements' contributory value in their as-is condition would
       approximate $12,500,000 ($50,000,000 x 25%).

             Another factor needs to be considered prior to concluding to the
       subject property's final as-is market value. A degree of negative market
       perception may be created if the subject property owner were unable to
       complete the improvements and another developer/owner had to be secured.
       Undoubtedly, the new buyer would incur additional expenditures to
       complete the improvements and, therefore, the existing improvements would
       be worth something less to a different developer or buyer. Additionally,
       the buyer of the incomplete subject improvements would be entitled to
       some entrepreneurial return for the effort and time expended to
       coordinate completion of the improvements. Market support for this
       entrepreneurial effort is virtually impossible to obtain. However, the
       as-is market value would undoubtedly be something less than simply 25% of
       the improvement's contributory value. Based on this analysis and assuming
       an exposure time of about one year, the subject property's as-is fee
       simple market value, as of September 17, 2001, is concluded at:

                              "TEN MILLION DOLLARS"
                                  ($10,000,000)

                                                                             110

                               IV. MARKETING TIME

             The client has also requested that an estimate of MARKETING TIME be
             provided, defined as:

             "AN OPINION OF THE AMOUNT OF TIME IT WOULD TAKE TO SELL A REAL OR
             PERSONAL PROPERTY INTEREST AT THE CONCLUDED MARKET VALUE LEVEL
             DURING THE PERIOD IMMEDIATELY AFTER THE EFFECTIVE DATE OF AN
             APPRAISAL."

             (Source: Advisory Opinion-7, UNIFORM STANDARDS OF PROFESSIONAL
             APPRAISAL PRACTICE (USPAP), adopted September 16, 1992, and last
             revised on September 15, 1999).

       A normal marketing time assumes a sale AFTER the appraisal's effective
       date and is normally anticipated by most lenders. (The client is a lender
       in this particular appraisal.) Lenders are concerned about their interest
       in the identified real estate even after the loan is secured. The
       development of a marketing time estimate uses much of the same
       methodology and sources referenced in developing the previous reasonable
       exposure time estimate. Likewise, it is a function of price, time, use,
       and anticipated market conditions.

             It is possible that a particular property's market value(s) could
       change during a specified marketing time as any significant change in
       economic conditions through the estimated marketing time could impact the
       property's ultimate future value(s). It may be inappropriate to assume
       that a particular property's market value(s) will simply remain stable
       during the marketing period/time. Therefore, it is technically incorrect
       for the appraisal's user to carry the current market value estimate(s)
       forward to the end of a concluded marketing period and simply "discount"
       the value(s) back to the present.

             The assembled market sources used in previously estimating the
       subject's one-two year exposure time indicate that an appropriate
       marketing time would also approximate one-two years. No market evidence
       exists to suggest that the subject property's market value would change
       measurably as it relates to the local or even regional ethanol fuel plant
       market within this one-two year time frame. Thus, this particular market
       segment should sustain the subject property's previously concluded market
       values through the one-two year estimated marketing time.
