Mr. Gary Kramer
Badger State Ethanol
12139 Howardsville Road
Lena, IL  61048

Dear Gary:

We have prepared this letter of intent between Badger State Ethanol (BSE) and
Continental Carbonic Products, Inc. (CCPI) to reflect our discussions to date
and to serve as the framework for negotiating definitive agreements between the
parties. If the following is acceptable, please sign and date the original
letter and return it to me. I have included an extra signed copy for your files.

It is the intention of the parties to enter into negotiations beginning with
the execution of this letter to establish contractual agreements by which CCPI
may (a) purchase up to 200 tons per day of raw carbon dioxide from BSE's
Monroe, Wisconsin plant with options for additional tonnage; (b) lease real
property from BSE in Monroe, Wisconsin upon which CCPI can construct a carbon
dioxide liquefaction and dry ice plant; and (c) purchase utilities, goods and
services from BSE in Monroe, Wisconsin in connection with the operation of the
plant to be constructed by CCPI. Neither party shall be obligated to perform
such contractual undertaking until such time as definitive agreements
acceptable to both parties are executed.

BSE recognizes that during this period CCPI will be negotiating with
prospective purchasers for the sale of food grade liquid and solid carbon
dioxide and will be incurring significant expense in planning o the
construction of the liquefaction/dry ice plant. Accordingly, BSE agrees that
from the date of execution of this letter it shall not enter into negotiations
with any third party for the sale of raw carbon dioxide produced at BSE's
Monroe, Wisconsin plant which will be used for the purpose of making food grade
liquid or solid carbon dioxide. This obligations of BSE shall cease when CCPI
notifies BSE in writing that CCPI elects not to construct a liquefaction/dry
ice plant on BSE premises in Monroe, Wisconsin or 4-1-01, whichever occurs
first. Such obligation may be extended by mutual agreement of the parties.

As indicated above, it is understood that the consummation of the transaction
contemplated by this Letter of Intent is subject to the parties negotiating and
executing a mutually satisfactory definitive contract, implementing the terms
indicated in the second paragraph of this letter and additional terms,
including but not limited to:

         (a)      A pricing structure for the raw carbon dioxide or the
                  twenty-year term that includes minimum take or pay provisions.
         (b)      A lease for the liquefaction/dry ice plant site.
         (c)      Easements to be provided by BSE to permit CCPI to supply
                  electrical power, other utilities and access to its facility.
         (d)      An understanding concerning utilities to be supplied to CCPI's
                  facility by BSE and to be determined according to their
                  certain availability.
         (e)      Types and limits of insurance.
         (f)      An understanding concerning non-competition and right of
                  assignability.
         (g)      An option on the part of CCPI to purchase additional
                  raw carbon dioxide.
         (h)      Other mutually agreeable terms.

2.   STATEMENT OF PURPOSE

2.1  Principal  Purposes - The principal purposes of the Plan are to provide the
Company with the advantages of the incentive  inherent in share ownership on the
part of employees,  officers,  directors,  and  consultants  responsible for the
continued  success of the Company;  to create in such  individuals a proprietary
interest in, and a greater  concern for, the welfare and success of the Company;
to encourage  such  individuals  to remain with the Company;  and to attract new
employees, officers, directors and consultants to the Company.

2.2  ISOs and  Non-ISOs - Under this Plan,  the Company may grant either ISOs or
Non-ISOs.  Each ISO granted  hereunder is intended to  constitute  an "incentive
stock  option",  for the purposes of section 422 of the Code,  and this Plan and
each such ISO is intended to comply with all of the  requirements of Section 422
of the Code and of all other  provisions  of the Code  applicable  to  incentive
stock options and to plans issuing the same. Each Non-ISO  granted  hereunder is
intended to constitute an Option that is not an "incentive stock option" for the
purposes  of  section  422 of the  Code,  and  that  does  not  comply  with the
requirements of Section 422 of the Code.

2.3  Benefit to  Shareholders - The Plan is expected to benefit  shareholders by
enabling the Company to attract and retain  personnel of the highest  caliber by
offering such  personnel an opportunity to share in any increase in value of the
Shares resulting from their efforts.

3.   ADMINISTRATION

3.1  Board or  Committee - The Plan shall be  administered  by the Board or by a
Committee appointed in accordance with Section 3.2 or 3.5(b) below.

3.2  Appointment  of  Committee - The Board may at any time appoint a Committee,
consisting of not less than two of its members, to administer the Plan on behalf

prescribe,  consistent  with this Plan.  Once  appointed,  the  Committee  shall
continue to serve until otherwise  directed by the Board. From time to time, the
Board may increase the size of the  Committee  and appoint  additional  members,
remove members (with or

<PAGE>

                                      -5-

without cause) and appoint new members in their place,  fill  vacancies  however
caused,  or  remove  all  members  of  the  Committee  and  thereafter  directly
administer the Plan.

3.3  Quorum and  Voting - A  majority  of the  members  of the  Committee  shall
constitute  a quorum,  and,  subject to the  limitations  in this Section 3, all
actions of the  Committee  shall  require  the  affirmative  vote of members who
constitute  a  majority  of such  quorum.  No member of the  Committee  who is a
director to whom an Option may be granted  may  participate  in the  decision to
grant  such  Option  (but any such  member may be  counted  in  determining  the
existence  of a quorum at any meeting of the  Committee in which action is taken
with respect to the granting of an Option to him).

Notwithstanding  the  foregoing  provisions  of this Section 3, in the event the
Company is or becomes  subject to the  provisions  of Section 16 of the Exchange
Act, the Board shall attempt to provide for  administration of the Plan, insofar
as it relates to the participation of officers, directors or stockholders of the
Company who are subject to the reporting and liability  provisions of Section 16
of the  Exchange  Act,  in a manner  which shall  qualify  the grant,  exercise,

16b-3 under the Exchange  Act, of any Shares  issued upon  exercise of an Option
unless at least six months has  elapsed  between the Date of Grant of the Option
and the date of disposition of the Shares issued upon exercise of such Option.

7.   LIMITATION ON GRANTS OF OPTIONS

7.1  Non-ISO if Exceed  $100,000 (U.S.) - If the aggregate Fair Market Value of:

     (a)  Shares underlying Options which are ISOs which have been granted to an
          Optionee under this Plan, and

     (b)  Shares  underlying  incentive stock options which have been granted to
          such  Optionee  under any other  plan of the  Company  or any  Related
          Company,

which are  exercisable  for the  first  time  during a  calendar  year,  exceeds
$100,000 (U.S.),  as such amount may be adjusted from time to time under Section
422(d) of the Code,  then,  to the extent of such excess,  such Options shall be
treated as Non-ISOs.

7.2  ISO Optionee  Owning Greater Than 10% of Voting  Securities - The Committee
may grant an ISO to an employee of the  Company or any Related  Company  who, at
the Date of  Grant,  owns  securities  of the  Company  or any  Related  Company
representing  more than 10% of the total combined voting power of all classes of
shares of the Company or any Related Company, only if:

     (a)  the  Option  Price is at least  110% of the Fair  Market  Value of the
          Shares at the Date of Grant; and

     (b)  the Term is five years or less.

8.   EXERCISE OF OPTION

8.1  Method of Exercise - Subject to any limitations or conditions  imposed upon
an Optionee  pursuant to the Option  Agreement or Section 6 hereof,  an Optionee
may exercise an Option by giving  written  notice  thereof to the Company at its
principal place of business.

8.2  Payment of Option  Price - The  notice  described  in Section  8.1 shall be
accompanied  by full  payment of the  aggregate  Option  Price to the extent the
Option is so exercised,  and full payment of any amounts the Company  determines
must be  withheld  for tax  purposes  from the  Optionee  pursuant to the Option
Agreement. Such payment shall be:

     (a)  in lawful money (Canadian funds) by cheque;

     (b)  at the  discretion  of the  Committee  and if such form of  payment is
          permitted  under the corporate  laws then  governing  the Company,  by
          delivery of the Optionee's  personal recourse note bearing interest at
          a rate deemed appropriate by the Committee;

     (c)  at the  discretion  of the  Committee,  and subject to all  applicable
          securities laws,  through delivery by the Optionee and/or  withholding
          by the  Company,  of  Shares  having a market  value as of the date of
          exercise equal to the cash exercise price of the Option

<PAGE>

                                      -10-

          plus any amounts that the Company determines must be withheld from the
          Optionee for U.S. or Canadian tax  purposes.  The market value of each
          of the  Shares on the date of  delivery  shall be  determined  in good
          faith by the Committee,  which  determination shall be binding for all
          purposes hereunder; or

     (d)  at  the  discretion  of  the  Committee,  by  any  combination  of the
          consideration contemplated by Sections 8.2(a) to 8.2(c) above.

8.3  Issuance of  Certificates  - As soon as  practicable  after  exercise of an
Option in accordance with Sections 8.1 and 8.2 hereof, the Company shall issue a
certificate  or  certificates  evidencing  the Shares with  respect to which the
Option  has  been  exercised.   Until  the  issuance  of  such   certificate  or
certificates,  no right to vote or receive  dividends  or any other  rights as a
shareholder  shall  exist  with  respect  to such  Shares,  notwithstanding  the
exercise of the Option. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the certificate is issued, except
as provided by Section 11 hereof.

9.   TRANSFERABILITY OF OPTIONS

9.1  Non-Transferable  - Except as provided otherwise in this Section 9, Options
     are non-assignable and non-transferable.

9.2  Death of  Optionee - If the  employment  of an  Optionee  as an employee or
consultant of the Company or any Related Company, or the position of an Optionee
as a director or officer of the Company or any Related Company,  terminates as a
result of his or her death,  any Options held by such Optionee shall pass to the
Qualified Successor of the Optionee, and

     (a)  in the case of an ISO, shall be exercisable by the Qualified Successor
          for a period of six months following such death, and

     (b)  in the  case of a  Non-ISO,  shall  be  exercisable  by the  Qualified
          Successor for a period of 12 months following such death,

provided  that in no case  shall the Term of the Option  extend  beyond 10 years
from the Date of Grant.

9.3  Disability of Optionee - If the employment of an Optionee as an employee or
consultant of the Company or any Related Company, or the position of an Optionee
as a director or officer of the Company or any Related Company, is terminated by
the Company or any Related Company by reason of such Optionee's Disability,  any
Option held by such Optionee that could have been exercised immediately prior to
such  termination of service shall be  exercisable  by such Optionee,  or by his
Guardian,  for a period of one year following the termination of service of such
Optionee.

9.4  Disability  and Death of  Optionee  - If an  Optionee  who has ceased to be
employed  by the  Company or any  Related  Company by reason of such  Optionee's
Disability dies within six months after the termination of such employment,  any
Option held by such Optionee that could have been

<PAGE>

                                      -11-

exercised  immediately  prior to his or her death  shall  pass to the  Qualified
Successor of such Optionee, and shall be exercisable by the Qualified Successor:

     (a)  in the case of an ISO, for a period of six months  following the death
          of such Optionee, and

     (b)  in the case of a  Non-ISO,  for a period  of 12 months  following  the
          death of such Optionee,

provided  that in no case  shall the Term of the Option  extend  beyond 10 years
from the Date of Grant.

9.5  Vesting  -  Options  held by a  Qualified  Successor  or  exercisable  by a
Guardian shall,  during the period prior to their termination,  continue to vest
in accordance with any vesting schedule to which such Options are subject.

9.6  Unanimous  Agreement  - If two or more  persons  constitute  the  Qualified
Successor or the Guardian of an Optionee, the rights of such Qualified Successor
or such Guardian shall be exercisable only upon the unanimous  agreement of such
persons.

9.7  Deemed  Non-Interruption  of  Employment  -  Employment  shall be deemed to
continue  intact  during any  military or sick leave or other bona fide leave of
absence if the  period of such leave does not exceed 90 days or, if longer,  for
so long as the Optionee's right to reemployment  with the Company or any Related
Company is  guaranteed  either by statute or by contract.  If the period of such
leave exceeds 90 days and the Optionee's reemployment is not so guaranteed, then
his or her employment shall be deemed to have terminated on the ninety-first day
of such leave.

10.  TERMINATION OF OPTIONS

10.1 Termination of Options - To the extent not earlier  exercised or terminated
in accordance with section 9 above, an Option shall terminate at the earliest of
the following dates:

     (a)  the  termination   date  specified  for  such  Option  in  the  Option
          Agreement;

     (b)  where the Optionee's  position as an employee,  consultant or director
          of the Company or any Related  Company is  terminated  for just cause,
          the date of such termination for just cause;

     (c)  where the Optionee's position as an employee,  consultant,  officer or
          director of the Company or any Related Company terminates for a reason
          other than the Optionee's  Disability,  death, or termination for just
          cause,  30 days after such date of  termination,  or upon the Optionee
          making written  application to the Committee and receiving the written
          consent of the Committee, which consent may be given at the discretion
          of the  Committee,  no later  than the  original  expiry  date of such
          Option when it was granted;

<PAGE>

                                      -12-

     (d)  the date of any sale,  transfer,  assignment or hypothecation,  or any
          attempted sale, transfer, assignment or hypothecation,  of such Option
          in violation of Section 9.1 above; and

     (e)  the date  specified in Section 11.2 below for such  termination in the
          event of a Terminating Event.

10.2 Lapsed Options - If Options are  surrendered,  terminated or expire without
being  exercised  in whole or in part,  new Options may be granted  covering the
Shares  not  purchased  under  such  lapsed  Options.  If  an  Option  has  been
surrendered  in  connection  with the  regranting  of a new  Option  to the same
Optionee on different  terms than the original  Option granted to such Optionee,
then the new Option is subject to  approval  of the stock  exchange on which the
Shares are listed.

11.  ADJUSTMENTS TO OPTIONS

11.1 Alteration in Capital Structure - If there is a material  alteration in the
capital structure of the Company resulting from a recapitalization, stock split,
reverse stock split, stock dividend, or otherwise, the Committee shall make such
adjustments to this Plan and to the Options then outstanding  under this Plan as
the  Committee   determines   to  be   appropriate   and  equitable   under  the
circumstances,  so that the  proportionate  interest  of the holder of each such
Option shall, to the extent practicable,  be maintained as before the occurrence
of such event. Such adjustments may include,  without limitation (a) a change in
the number or kind of shares of the Company  covered by such Options,  and (b) a
change in the Option  Price  payable  per  share;  provided,  however,  that the
aggregate Option Price applicable to the unexercised portion of existing Options
shall not be altered,  it being intended that any adjustments  made with respect
to such Options shall apply only to the price per share and the number of shares
subject thereto.  For purposes of this Section 11.1, neither (i) the issuance of
additional shares of stock of the Company in exchange for adequate consideration
(including services), nor (ii) the conversion of outstanding preferred shares of
the  Company  into  Shares  shall be deemed to be  material  alterations  of the
capital structure of the Company. If the Committee determines that the nature of
a material alteration in the capital structure of the Company is such that it is
not practical or feasible to make appropriate adjustments to this Plan or to the
Options granted  hereunder,  such event shall be deemed a Terminating  Event for
the purposes of this Plan.

11.2 Terminating Events - Subject to Section 11.3, all Options granted under the
Plan shall terminate upon the occurrence of a Terminating Event.

11.3 Notice of Terminating  Event - The Committee shall give notice to Optionees
not less than thirty days prior to the consummation of a Terminating Event. Upon
the giving of such  notice,  all  Options  granted  under the Plan shall  become
immediately  exercisable,  notwithstanding  any contingent  vesting provision to
which such Options may have otherwise been subject.

11.4 Corporate  Reorganization - In the event of a reorganization  as defined in
this  Section  11.4 in which  the  Company  is not the  surviving  or  acquiring
corporation,  or in which the Company is or becomes a wholly-owned subsidiary of
another corporation after the effective date of the reorganization,  then unless
provision is made by the acquiring corporation for the assumption of each

<PAGE>

                                      -13-

Option granted under this Plan, or the substitution of an option therefor,  such
that no Modification  of any such Option occurs,  all Options granted under this
Plan shall  terminate  and such event shall be deemed a Terminating  Event.  For
purposes of this Section 11.4,  reorganization  shall mean any statutory merger,
statutory  consolidation,  sale of all or substantially all of the assets of the
Company,  or sale,  pursuant to an agreement with the Company,  of securities of
the  Company  pursuant  to  which  the  Company  is or  becomes  a  wholly-owned
subsidiary   of   another   corporation   after  the   effective   date  of  the
reorganization.

11.5 Acceleration  on Change  of  Control  - Upon a Change  in  Control,  at the
discretion of the Compensation  Committee,  all Options shall become immediately
exercisable,  notwithstanding  any contingent  vesting  provisions to which such
Options may have otherwise been subject.

11.6 Acceleration  of Date of Exercise - The  Committee  shall have the right to
accelerate the date of exercise of any installment of any Option; provided that,
without the consent of the Optionee  with respect to any Option,  the  Committee
shall not  accelerate  the date of any  installment  of any Option granted to an
employee  as an ISO (and not  previously  converted  into a Non-ISO  pursuant to
Section  13  below)  if such  acceleration  would  violate  the  annual  vesting
limitation  contained in Section 422(d) of the Code, as described in Section 7.1
above.

11.7 Determinations  to be Made By Committee -  Adjustments  and  determinations
under this Section 11 shall be made by the Committee,  whose decisions as to the
adjustments or determination which shall be made, and the extent thereof,  shall
be final, binding, and conclusive.

11.8 Effect of a Take-over If a bona fide offer (the "Offer") for Shares is made
to an Optionee or to shareholders  generally or to a class of shareholders which
includes the  Optionee,  which  Offer,  constitutes  a take-over  bid within the
meaning of section 89(1) of the Ontario  Securities Act, as amended from time to
time, the Company shall, immediately upon receipt of notice of the Offer, notify
each Optionee of full particulars of the Offer,  whereupon any Option held by an
Optionee  may be  exercised  in whole or in part by the Optionee so as to permit
the Optionee to tender the Shares  received upon such  exercise  (the  "Optioned
Shares") to the Offer. If:

     (a)  the Offer is not completed within the time specified therein; or

     (b)  all of the Optioned  Shares  tendered by the Optionee  pursuant to the
          Offer are not taken up and paid for by the offeror pursuant thereto;

the Optioned Share or, in the case of clause (b) above, the optioned Shares that
are not taken up and paid for,  may be returned  by the  Optionee to the Company
and  reinstated  as  authorized  but  unissued  shares and with  respect to such
returned  Optioned Shares,  the Option shall be reinstated as if it had not been
exercised.  If any  Optioned  Shares  are  returned  to the  Company  under this
Section,  the Company  shall refund the exercise  price to the Optionee for such
Optioned Shares.

12.  TERMINATION AND AMENDMENT OF PLAN

12.1 Termination of Plan - Unless  earlier  terminated as provided in Section 11
above or in Section 12.2 below, the Plan shall terminate on, and no Option shall
be  granted  under the Plan on or after,  the date  which is ten years  from the
Effective Date of the Plan.

12.2 Power of  Committee to Terminate or Amend Plan - Subject to the approval of
any stock exchange on which the Company is listed,  the Committee may terminate,
suspend  or amend the  terms of the Plan;  provided,  however,  that,  except as
provided  in Section 11 above,  the  Committee  may not do any of the  following
without  obtaining,  within 12  months  either  before or after the  Committee's
adoption of a resolution  authorizing  such action,  approval by the affirmative
votes of the  holders of a  majority  of the voting  securities  of the  Company
present,  or  represented,  and  entitled  to vote  at a  meeting  duly  held in
accordance with the applicable  corporate laws, or by the written consent of the
holders of a majority of the securities of the Company entitled to vote:

     (a)  increase the aggregate  number of Shares which may be issued under the
          Plan;

     (b)  materially modify the requirements as to eligibility for participation
          in the Plan,  or change the  designation  of the employees or class of
          employees eligible to receive ISOs under the Plan;

     (c)  materially  increase the benefits  accruing to participants  under the
          Plan; or

     (d)  make any  change in the terms of the Plan  that  would  cause the ISOs
          granted  hereunder to lose their  qualification  as  "incentive  stock
          options" under Section 422 of the Code;

however,  the  Committee  may amend  the  terms of the Plan to  comply  with the
requirements  of any  applicable  regulatory  authority,  without  obtaining the
approval of its shareholders.

12.3 No Grant During  Suspension  of Plan - No Option may be granted  during any
suspension,  or  after  termination,  of  the  Plan.  Amendment,  suspension  or
termination of the Plan shall not, without the consent of the Optionee, alter or
impair any rights or obligations under any Option previously granted.

13.  CONVERSION OF ISOs INTO NON-ISOs

13.1 Conversion  of ISOs  into  Non-ISOs  - At the  written  request  of any ISO
Optionee,  the  Committee  may in its  discretion  take such  actions  as may be
necessary to convert such  Optionee's  ISOs (or any  installments or portions of
installments  thereof)  that have not been  exercised on the date of  conversion
into Non-ISOs at any time prior to the  expiration  of such ISOs,  regardless of
whether the  Optionee is an employee of the Company or a Related  Company at the
time of such  conversion.  Such  actions  include,  but shall not be limited to,
extending  the  exercise  period  of such  ISOs,  provided,  however,  that such
exercise  period shall in no event exceed 10 years  following  the Date of Grant
without approval of The Toronto Stock Exchange.  At the time of such conversion,
the Committee,

<PAGE>

                                      -15-

with the consent of the Optionee,  may impose such conditions on the exercise of
the  resulting  Non-ISOs  as the  Committee  in its  discretion  may  determine,
provided that such conditions are consistent with this Plan. Nothing in the Plan
shall be deemed to give any  Optionee  the  right to have such  Optionee's  ISOs
converted into Non-ISOs, and no such conversion shall occur until and unless the
Committee  takes  appropriate  action.  The  Committee,  with the consent of the
Optionee,  may also terminate any portion of any ISO that has not been exercised
at the time of such conversion.

14.  CONDITIONS PRECEDENT TO ISSUANCE OF SHARES

14.1 Compliance  with Laws - Shares shall not be issued pursuant to the exercise
of any  Option  unless the  Shares  are fully  paid and  non-assessable  and the
exercise of such Option and the issuance and delivery of such Shares comply with
all relevant provisions of law, including, without limitation, the United States
Securities  Act  of  1933,  as  amended,  any  applicable  state  or  provincial
securities or corporate laws, the rules and regulations  promulgated thereunder,
and the  requirements  of any stock  exchange  upon which the Shares may then be
listed or otherwise traded.

14.2 Representations  by Optionee - As a condition  precedent to the exercise of
any Option,  the Company may require the Optionee to represent  and warrant,  at
the time of exercise,  that the Shares are being  purchased  only for investment
and without any present  intention to sell or distribute  such Shares if, in the
opinion of counsel for the Company,  such  representations  and  warranties  are
required by any applicable law.

14.3 Regulatory  Approval  to Issuance of Shares - The  Company's  inability  to
obtain authority from any regulatory body having  jurisdiction,  which authority
is deemed by the  Company's  counsel to be necessary to the lawful  issuance and
sale of any Shares  hereunder,  shall relieve the Company of any liability  with
respect to the failure to issue or sell such Shares.

15.  USE OF PROCEEDS

15.1 Use of Proceeds - Proceeds from the sale of Shares  pursuant to the Options
granted  and  exercised  under the Plan shall  constitute  general  funds of the
Company and shall be used for general corporate purposes.

or permitted to be given under this Plan and the Options granted under this Plan

notice is to be given,  in which case  notice  shall be deemed to have been duly
given on the date of such  service;  telefaxed,  in which case  notice  shall be
deemed to have been duly given on the date the telefax is sent; or mailed to the
party  to whom  notice  is to be  given,  by first  class  mail,  registered  or

obligate  the  Company  or any  Related  Company  to  retain an  Optionee  as an
employee,  officer,  director, or consultant for any period, nor shall this Plan
interfere  in any way with the right of the  Company or any  Related  Company to
reduce such Optionee's compensation.

with an Optionee shall be binding upon such Optionee and the Qualified Successor
