          PROSPECTUS OF               INFORMATION STATEMENT OF
       DONLAR CORPORATION           DONLAR BIOSYNTREX CORPORATION
</Table>

     WE ARE REGISTERING 20,793,360 SHARES OF DONLAR COMMON STOCK, NO PAR VALUE.
NO PUBLIC MARKET CURRENTLY EXISTS FOR DONLAR COMMON STOCK. THE AVERAGE BID AND
ASK PRICE OF DONLAR BIOSYNTREX COMMON STOCK AS REPORTED ON THE NASD
OVER-THE-COUNTER BULLETIN BOARD ON DECEMBER 4, 2002, WAS $0.135.

     The boards of directors of Donlar Corporation and Donlar Biosyntrex
Corporation have unanimously approved the merger of the two companies. The
holders of Donlar's common stock and preferred stock, except as otherwise
provided in this information statement/prospectus, will receive approximately
0.49 shares of combined company common stock for each share of Donlar common
stock or preferred stock that they own. The holders of Donlar Biosyntrex's
common stock (other than Donlar) and Series B preferred stock will receive
approximately 0.26 shares of combined company common stock for each share of
Donlar Biosyntrex stock that they own and the holders of Donlar Biosyntrex's
Series A preferred stock will receive one share of combined company common stock
for each originally issued share of Series A preferred stock that they own.
Donlar has adopted a 2002 Equity Incentive Plan as described in this information
statement/prospectus which, if approved by the companies' shareholders, will be
effective upon consummation of the merger.

     Each of us will hold a meeting of our shareholders on February   , 2003 to
consider and vote on the approval of the merger and the adoption of the equity
incentive plan. We are required to send Donlar Biosyntrex shareholders a copy of
this information statement/prospectus at least 20 calendar days prior to the
meeting date. The merger must be approved by a majority of the Donlar Biosyntrex
common and Series A preferred shareholders and by two-thirds of the Donlar
common shareholders. Because Donlar owns approximately 68% of the Donlar
Biosyntrex common stock and Dr. Kamal Modir, Peter LeDonne, Jr. and Kenneth
Hubbard, collectively owning or controlling a majority of the Donlar Biosyntrex
Series A preferred stock, and Dr. Robert Martin, the Willis Stein Group and
Donlar's executive officers, collectively owning or controlling approximately
84% of the voting interests in Donlar, have entered into agreements to vote for
the approval of the merger, Donlar and Donlar Biosyntrex can cause the merger to
occur without the affirmative vote of any other holder of shares. Donlar also
has sufficient votes to cause the approval of the adoption of the equity
incentive plan by the Donlar Biosyntrex shareholders without the affirmative
vote of any other shareholder.

     WE ARE NOT ASKING YOU FOR A PROXY AND DO NOT SEND US A PROXY

     Please read this information statement/prospectus carefully. YOU SHOULD
READ THE "RISK FACTORS" SECTION BEGINNING ON PAGE 10 FOR A DESCRIPTION OF
VARIOUS RISKS YOU SHOULD CONSIDER IN EVALUATING THE MERGER AND THE EQUITY
INCENTIVE PLAN. This document incorporates important business and financial
information about Donlar and Donlar Biosyntrex. See "Where You Can Find More

                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

     Donlar Biosyntrex Corporation will hold a special meeting of shareholders
at its offices at 6502 South Archer Road, Bedford Park, Illinois 60501 on
February   , 2003 at 11:00 a.m. local time to consider and vote upon a proposal
to adopt the Amended and Restated Agreement and Plan of Merger, dated as of June
7, 2002, between Donlar Biosyntrex and Donlar Corporation, an Illinois
corporation and majority shareholder of Donlar Biosyntrex, and, in connection
with the merger, a proposal to approve the adoption of Donlar's 2002 Equity
Incentive Plan. Under the merger agreement, among other things:

     - Donlar Biosyntrex will merge with Donlar, with Donlar being the surviving
       corporation;

     - the articles of incorporation of Donlar will be the articles of
       incorporation of the combined company and will be amended to increase the
       total number of authorized shares of capital stock from 60,000,000 shares
       of common stock and 38,000,000 shares of preferred stock to 200,000,000
       shares of common stock and 100,000,000 shares of preferred stock;


     - the outstanding shares of Donlar Biosyntrex common stock (other than
       those owned by Donlar) and Series A and Series B preferred stock will
       convert into the right to receive approximately 4.0 million and 21,000
       shares of common stock, respectively, of the combined company upon
       completion of the merger which collectively will represent approximately
       19.5% of the outstanding combined company common stock and 4.4% on a
       fully diluted basis;


     - the shares of Donlar common stock and preferred stock owned by Dr. Robert
       Martin, Willis Stein & Partners, L.P. and its affiliate, Star Polymers,
       L.L.C., and the debt and other interests in Donlar and Donlar Biosyntrex
       owned by them, will be exchanged for shares of the combined company
       common and preferred stock in accordance with the restructuring plan
       described in the information statement/prospectus. The shares of Donlar
       common stock owned by TFIC, Inc. will be cancelled. All other outstanding
       shares of Donlar common and preferred stock will convert into the right
       to receive approximately 1.4 million and 7.3 million shares of combined
       company common stock, respectively, upon completion of the merger,
       collectively representing approximately 41.6% of the outstanding combined
       company common stock and 9.4% on a fully diluted basis;

     - all issued and outstanding shares of Donlar Biosyntrex owned by Donlar
       will be cancelled;

     - all outstanding warrants, options or rights of any kind to acquire any
       shares of capital stock or other securities of any kind from Donlar or
       Donlar Biosyntrex will be cancelled except for Donlar's and Donlar
       Biosyntrex's principal lender's right to acquire shares of Donlar's
       common stock upon conversion of certain loans as described in the
       information statement/prospectus; and

     - the board of directors of the combined company will consist of the
       current members of the Donlar board (which is currently identical to the
       Donlar Biosyntrex board).

     The 2002 Equity Incentive Plan will be effective upon approval by the
shareholders and consummation of the merger. The equity incentive plan contains
essentially the same terms as the Donlar Biosyntrex 2001 Equity Incentive Plan.
It will authorize an aggregate of 5.0 million shares of combined company common
stock to be used for awards to directors, management, employees and consultants
of the combined company and its subsidiaries.

     We describe the merger agreement and the equity incentive plan more fully
in the attached information statement/prospectus, which includes as Appendix A,
a copy of the merger agreement and as Appendix B a copy of the equity incentive
plan.

     The affirmative vote of the holders of a majority of the outstanding shares
of Donlar Biosyntrex common stock and Series A preferred stock, on an as
converted basis, voting as a single class, is required to approve the merger
agreement and approve the adoption of the equity incentive plan. The merger must
also be approved by a majority of the outstanding shares of Series A preferred
stock voting as a separate class. Donlar Biosyntrex has written agreements with
the holders of a majority of the outstanding shares of Series A


preferred stock providing that such holders will (a) exchange their Series A
preferred stock for combined company common stock on the basis of one share of
combined company common stock for each share of originally issued Series A
preferred stock (i.e., excluding dividend shares) (totaling approximately 21,000
shares) and (b) vote for approval of the merger agreement and the related
transactions.

     We have fixed the close of business on January 10, 2003 as the record date
for determining the shareholders of Donlar Biosyntrex entitled to vote at the
Donlar Biosyntrex special meeting and any adjournments or postponements of the
meeting. Only holders of record of Donlar Biosyntrex common stock and Series A
preferred stock at the close of business on that date are entitled to notice of
and to vote at the Donlar Biosyntrex special meeting. Because Donlar holds 68%
of the outstanding common stock in Donlar Biosyntrex and has written agreements
with the holders of a majority of the outstanding Series A preferred stock to
vote for approval of the merger agreement and related transactions, it can cause
approval of the merger and the adoption of the equity incentive plan without the
affirmative vote of any other holder of shares.

     The board of directors of Donlar Biosyntrex, in accordance with Nevada law,
unanimously recommends that you vote "FOR" approval of the merger agreement and
"FOR" approval of the adoption of the equity incentive plan.

     Donlar Biosyntrex shareholders have the right to dissent from the merger
agreement and receive a payment in cash of the fair value of their Donlar
Biosyntrex shares by strictly complying with the requirements of Nevada law as
described in the attached information statement/prospectus and Appendix C
thereto.

     WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US A
PROXY.

     Please read this information statement/prospectus carefully. In particular,
you should read the "Risk Factors" section for a description of various risks
you should consider in evaluating the merger.

                                          By Order of the Board of Directors of
                                          Donlar Biosyntrex Corporation

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: WHY ARE THE TWO COMPANIES PROPOSING TO MERGE?

A: The board of directors of Donlar and Donlar Biosyntrex have adopted a
   restructuring plan, which is fully described under "Proposal 1 -- Approval of
   the Agreement and Plan of Merger -- Background of the Merger -- Restructuring
   Plan" and "Proposal 1 -- Approval of the Agreement and Plan of Merger --
   Determination of the Terms of the Merger and Restructuring Plan," that will
   result in the companies' liabilities being reduced from approximately $48.92
   million to approximately $23.66 million. Under this plan, Donlar and Donlar
   Biosyntrex have entered into a Bridge and Consolidated Term Loan Agreement
   with the companies' principal lender, Tennessee Farmers Life Insurance
   Company. Tennessee Farmers, as a condition of making the bridge loan and
   restructuring certain existing loans to Donlar and Donlar Biosyntrex under
   the loan agreement, required that the merger be completed by July 7, 2002,
   unless such date is extended by Tennessee Farmers. Tennessee Farmers has
   extended the date for completion of the merger until February 28, 2003. If
   the companies fail to complete the merger by February 28, 2003, and Tennessee
   Farmers does not agree to extend the completion date, it would constitute a
   default under the loan agreement that would permit the lender to accelerate
   the loans, terminate any commitment to lend additional funds under the bridge
   loan facility (currently with approximately $340,000 of borrowing capacity
   remaining) and charge the default rate of interest. Tennessee Farmers is
   requiring and the companies have agreed to use their best efforts to complete
   the merger because it will simplify the companies' capital structure thereby
   reducing accounting and legal costs and making the companies more attractive
   to potential investors and lenders. In addition, since the bridge loan and
   the restructuring of the existing Tennessee Farmers loans were necessary for
   the companies to continue in operation, and Tennessee Farmers is requiring
   the merger as a condition of those transactions, we believe that the merger
   is in the best interests of the companies and their shareholders.

Q: WHAT WILL BE THE NAME OF THE COMBINED COMPANY?

A: The surviving corporation in the merger will be named Donlar Corporation.

Q: WILL THE COMBINED COMPANY HAVE A NEW SYMBOL ON THE NASD BULLETIN BOARD?

A: Yes. The combined company will apply for authorization to trade on the NASD
   over-the-counter bulletin board and for a new symbol upon completion of the
   merger.

Q: WHAT WILL DONLAR BIOSYNTREX SHAREHOLDERS RECEIVE FOR THEIR SHARES?


A: Donlar owns approximately 68% of the outstanding Donlar Biosyntrex common
   stock and the other Donlar Biosyntrex shareholders own 32%. The holders of
   Donlar Biosyntrex common stock (other than Donlar) and the holders of Donlar
   Biosyntrex Series B preferred stock will receive approximately 0.26 shares of
   common stock of the combined company for each share of Donlar Biosyntrex
   common stock that they own. The holders of Donlar Biosyntrex Series A
   preferred stock will receive one share of combined company common stock for
   each share of originally issued Series A preferred stock (i.e., excluding
   dividend shares). All of the issued and outstanding shares of Donlar
   Biosyntrex owned by Donlar will be cancelled. The combined company will not
   issue fractional shares in the merger. The total number of shares of the
   combined company's common stock that each Donlar Biosyntrex shareholder will
   receive in the merger will be rounded up to the nearest whole number if the
   fractional share exceeds 0.5 and rounded down to the nearest whole number
   otherwise. The Donlar Biosyntrex shareholders (other than Donlar), upon
   completion of the merger and the other restructuring transactions, will own
   approximately 19.5% of the outstanding combined company common stock and 4.4%
   on a fully diluted basis.


Q: WHAT WILL DONLAR SHAREHOLDERS RECEIVE FOR THEIR SHARES?

A: Donlar owns approximately 68% of the outstanding Donlar Biosyntrex common
   stock. The holders of Donlar's common stock and preferred stock (other than
   TFIC, Inc., an affiliate of Tennessee Farmers, Willis Stein & Partners, L.P.
   and its affiliate, Star Polymers, L.L.C., and Dr. Robert Martin) will receive
   approximately 0.49 shares of common stock of the combined company for each
   share of Donlar common stock or preferred stock that they own. The total
   number of shares of the combined company's common

                                        1


   stock that each Donlar shareholder will receive in the merger will be rounded
   up to the nearest whole number if the fractional share exceeds 0.5 and
   rounded down to the nearest whole number otherwise. As a result of shares
   issued in the merger, the Donlar shareholders (other than TFIC, Inc., Willis
   Stein/Star Polymers and Dr. Robert Martin, and excluding the additional
   shares to be issued to Tennessee Rural Health Improvement Association) will
   own approximately 41.6% of the outstanding combined company common stock and
   9.4% on a fully diluted basis.

Q: WHAT WILL WILLIS STEIN & PARTNERS, L.P., STAR POLYMERS, L.L.C. AND DR. ROBERT
   MARTIN RECEIVE FOR THEIR DEBT, EQUITY AND CERTAIN OTHER INTERESTS IN DONLAR
   AND DONLAR BIOSYNTREX?


A: Willis Stein & Partners, L.P. and its affiliate, Star Polymers, L.L.C., will
   collectively receive senior convertible preferred stock of the combined
   company with a stated liquidation value of $9.0 million and convertible into
   approximately 13.23 million shares of common stock of the combined company in
   exchange for $9.0 million of original principal amount of notes plus accrued
   interest and will receive 1.0 million shares of common stock of the combined
   company in exchange for approximately 20.3 million shares of Donlar preferred
   stock. Dr. Martin will receive senior convertible preferred stock of the
   combined company with a stated liquidation value of $9.0 million and
   convertible into approximately 13.23 million shares of common stock of the
   combined company in exchange for approximately $9.9 million of original
   principal amount of notes plus accrued interest, will receive 5.0 million
   shares of common stock of the combined company in exchange for the
   relinquishment of his rights to receive royalty payments and for
   approximately 16.6 million shares of Donlar common and preferred stock and
   will receive a warrant to purchase 3.0 million shares of common stock of the
   combined company for $0.68 per share in exchange for cancellation of existing
   options and warrants to purchase approximately 38.4 million shares of Donlar
   common and preferred stock. Dr. Martin will also receive 1,187,940 shares of
   combined company common stock in exchange for the 4,569,000 shares of Donlar
   Biosyntrex common stock that he owns based on the exchange rate in the
   merger.


Q: WHAT WILL THE COMPANIES' OTHER MAJOR CREDITORS HOLD AFTER THE RESTRUCTURING?

A: Donlar Biosyntrex and Donlar are borrowers under a term loan agreement with
   Tennessee Farmers Life Insurance Company pursuant to which they obtained a
   bridge loan facility and restated certain previously existing secured loans.
   The bridge loan facility is for up to $2.127 million and will be convertible
   into shares of the combined company common stock at a rate of one share per
   $0.29 of outstanding principal amount of the loan. The restated loans are in
   the total amount of $19.2 million and will be convertible into shares of the
   combined company common stock at a rate of one share per $0.68 of outstanding
   principal amount of the loans. The maximum number of shares issuable upon
   conversion of the loans is approximately 34.4 million which after completion
   of the restructuring including the merger would constitute approximately 37%
   of the combined company common stock on a fully diluted basis. As part of the
   restructuring, the combined company will issue approximately 1.6 million
   shares of its common stock to Tennessee Rural Health Improvement Association
   and approximately 3.85 million shares of Donlar common stock owned by TFIC,
   Inc., an affiliate of Tennessee Farmers, will be cancelled with no shares
   being issued in the merger. To further eliminate debt from the balance sheet
   of Donlar and Donlar Biosyntrex, and after the merger, the combined company,
   Donlar has reached agreements with all fifteen of the holders of notes issued
   by Donlar in 1998 and 2000 in a total original principal amount of
   approximately $1.9 million to exchange their notes for shares of senior
   convertible preferred stock with an aggregate stated liquidation value equal
   to the total amount of the notes and convertible into approximately 2.8
   million shares of common stock of the combined company.

Q: HOW WERE THE MERGER EXCHANGE RATIOS DETERMINED?

A: The merger is a merger between Donlar Biosyntrex and Donlar, which is the
   owner of approximately 68% of the outstanding common stock of Donlar
   Biosyntrex. The merger is an integral part of the restructuring plan which
   will result in the elimination of approximately $25.26 million of the
   companies' liabilities. The companies' major creditors, namely Tennessee
   Farmers, Willis Stein & Partners, Dr. Martin and the 1998 and 2000
   noteholders, negotiated with the companies to receive convertible debt or
   preferred stock and, in some cases, shares of common stock of the combined
   company, as part of the restructuring transactions

                                        2



   described above and at "Proposal 1 -- Approval of the Agreement and Plan of
   Merger -- Background of the Merger -- Restructuring Plan" and "Proposal
   1 -- Approval of the Agreement and Plan of Merger -- Determination of the
   Terms of the Merger and Restructuring Plan." These creditors negotiated to
   receive in total approximately 80.5% of the combined company common stock on
   a fully diluted basis and approximately 37.4% on an outstanding basis. It was
   agreed that 5.41% of the combined company common stock on a fully diluted
   basis would be reserved for issuance under an equity incentive plan and 0.5%
   of the combined company common stock on a fully diluted basis (2.24% on an
   outstanding basis) would be issued to certain other creditors in exchange for
   claims against the companies. The remaining 13.6% of the combined company
   common stock on a fully diluted basis would be issued in the merger to the
   Donlar and Donlar Biosyntrex shareholders (other than Donlar, Willis
   Stein/Star Polymers and TFIC, Inc.). The restructuring as negotiated
   contemplates that after completion there will be a total of approximately
   20.8 million shares of combined company common stock outstanding and
   approximately 92.4 million shares on a fully diluted basis. The total number
   of shares to be issued was selected as a means of achieving the negotiated
   percentages.



  To achieve the above stated percentages, 12.7 million shares of the combined
  company common stock, representing approximately 61.1% of the common stock on
  an outstanding basis and 13.7% on a fully diluted basis, will be issued in the
  merger to the Donlar and Donlar Biosyntrex shareholders (other than Donlar,
  Willis Stein/Star Polymers and TFIC, Inc.). The 12.7 million shares is being
  allocated between the Donlar and Donlar Biosyntrex shareholders on the basis
  of the respective ownership of Donlar Biosyntrex common stock by Donlar on the
  one hand (i.e., 68%) and all other shareholders of Donlar Biosyntrex on the
  other hand. Therefore, the Donlar shareholders will receive in the aggregate
  68% of the 12.7 million shares, or 8.7 million shares, and the Donlar
  Biosyntrex shareholders will receive in the aggregate 32% of the 12.7 million
  shares, or 4.0 million shares.


     The following table reflects the allocation of the combined company common
stock as discussed above. A more detailed version of the table is contained
under "Proposal 1 -- Approval of the Agreement and Plan of
Merger -- Determination of the Terms of the Merger and Restructuring Plan."

Q: WHO WILL MANAGE THE COMBINED COMPANY?

A: The board of directors and executive officers of Donlar and Donlar Biosyntrex
   are currently identical. The board of directors and executive officers of the
   combined company will be the same as the board of directors and executive
   officers of the companies immediately prior to the merger.

                                        3


Q: WHAT DO I NEED TO DO NOW?

A: The affirmative vote of the holders of a majority of the outstanding shares
   of Donlar Biosyntrex common stock and Series A preferred stock, on an as
   converted basis, voting as a single class, is required to approve the merger
   agreement and approve the adoption of the equity incentive plan. The merger
   must also be approved by a majority of the outstanding shares of Series A
   preferred stock, voting as a separate class.

   Action by the Donlar Biosyntrex shareholders on the approval of the merger
   agreement and the adoption of the equity incentive plan will be taken at the
   Donlar Biosyntrex special meeting on January   , 2003. Donlar Biosyntrex must
   send you a copy of this information statement/prospectus at least 20 calendar
   days before its special meeting.

  Donlar Biosyntrex is not soliciting proxies and asks that you not send us a
  proxy. Donlar Biosyntrex has written agreements with Dr. Kamal Modir, Peter
  LeDonne, Jr. and Kenneth Hubbard, collectively owning or controlling a
  majority of the outstanding shares of Series A preferred stock, providing that
  such holders will (a) exchange their Series A preferred stock for combined
  company common stock on the basis of one share of combined company common
  stock for each share of originally issued Series A preferred stock (i.e.,
  excluding dividend shares) and (b) vote for approval of the merger agreement
  and the related transactions. Donlar Biosyntrex has an agreement with Donlar,
  the holder of a majority of the voting interest in Donlar Biosyntrex, to vote
  its shares in Donlar Biosyntrex to approve the merger agreement and the
  related transactions and in favor of approving the adoption of the Donlar 2002
  Equity Incentive Plan. Therefore, Donlar Biosyntrex can obtain approval of the
  transactions without the vote of any other shareholder. However, you should
  carefully read this document, may attend the Donlar Biosyntrex special meeting
  and may vote in person or by proxy, as provided below under "How do I vote?".

  The merger agreement must also be approved by the affirmative vote of the
  holders of two thirds of the outstanding shares of Donlar common and preferred
  stock voting as a single class. Donlar has agreements with the Willis Stein
  Group, Dr. Martin and its executive officers, collectively holding in excess
  of two-thirds of the outstanding voting interests in Donlar, to vote their
  shares in Donlar to approve the merger agreement.

Q: HOW DO I VOTE?

A: You can vote by attending the Donlar Biosyntrex special meeting on February
     , 2003, in person or by arranging to have your shares voted by a duly
   authorized proxy. However, Donlar Biosyntrex is not soliciting proxies and
   asks that you not send us one. If you wish to vote by proxy, you must
   properly designate a proxy in accordance with Nevada law and your proxy must
   attend the meeting and vote your shares. Only record holders of shares or
   their designated proxies will be permitted to vote at the meeting.

Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: No. You should not send in your stock certificates at this time. After the
   merger, the certificates currently representing shares of Donlar and Donlar
   Biosyntrex common stock and preferred stock will then represent the right to
   receive a certain number of shares of common stock of the combined company.
   Following the merger, the combined company will mail instructions to all
   Donlar and former Donlar Biosyntrex shareholders for exchanging their stock
   certificates.

Q: WHEN DO YOU EXPECT TO MERGE?

A: We expect to complete the merger shortly after receipt of the shareholder
   approvals.

manufacturing and distributing crop management and oil field products using a
protein technology with the potential to replace a generation of older,
non-biodegradable and potentially toxic chemicals. This new family of
biopolymers, known as thermal polyaspartates or TPA, is non-hazardous,
non-toxic, hypoallergenic, environmentally friendly and biodegradable. These
proteins are used in a broad range of industrial, agricultural and consumer
markets.

NATURE OF THE MERGER (SEE PAGE 29)

     The merger will combine Donlar and Donlar Biosyntrex with Donlar being the

     The merger is part of a restructuring plan, described at "Proposal
1 -- Approval of Agreement and Plan of Merger -- Background of the
Merger -- Restructuring Plan" and "Proposal 1 -- Approval of Agreement and Plan
of Merger -- Determination of the Terms of the Merger and Restructuring Plan,"

PAGES 26-29)

     The holders of Donlar Biosyntrex common stock (excluding Donlar) own
approximately 32% of the outstanding Donlar Biosyntrex common stock and will
receive approximately 0.26 shares of common stock of the combined company for
each share of Donlar Biosyntrex common stock that they own. All issued and
outstanding shares of Donlar Biosyntrex owned by Donlar will be cancelled. The
holders of Donlar Biosyntrex Series B preferred stock will receive approximately
0.26 shares of common stock of the combined company for each share of Donlar
preferred stock that they own (totaling 449). Donlar Biosyntrex has reached
agreement with the holders of a majority of its outstanding shares of Series A
preferred stock providing that such holders will (a) exchange their Series A
preferred stock for combined company common stock on the basis of one

                                        5



share of combined company common stock for each share of originally issued
Series A preferred stock (i.e., excluding dividend shares) and (b) vote for
approval of the merger agreement and the related transactions. The total number
of shares of the combined company's common stock that each Donlar Biosyntrex
shareholder will receive in the merger will be rounded up to the nearest whole
number if the fractional share exceeds 0.5 and rounded down to the nearest whole
number otherwise. The Donlar Biosyntrex shareholders (other than Donlar), upon
completion of the merger and the other restructuring transactions, will own
approximately 19.5% of the outstanding combined company common stock and 4.4% on
a fully diluted basis.


WHAT DONLAR SHAREHOLDERS WILL RECEIVE AS A RESULT OF THE MERGER (SEE PAGES
26-29)

     Donlar owns approximately 68% of the outstanding Donlar Biosyntrex common
stock. The holders of Donlar's common stock and preferred stock (other than Dr.
Robert Martin and Willis Stein/Star Polymers, whose debt, equity and certain
other interests in Donlar and Donlar Biosyntrex will be exchanged for shares of
the combined company in accordance with the restructuring plan, and TFIC, Inc.
whose shares of Donlar stock will be cancelled) will receive approximately 0.49
shares of common stock of the combined company for each share of Donlar common
stock or preferred stock that they own. The combined company will not issue
fractional shares in the merger. The total number of shares of the combined
company's common stock that each Donlar shareholder will receive in the merger
will be rounded up to the nearest whole number if the fractional share exceeds
0.5 and rounded down to the nearest whole number otherwise. As a result of the
shares issued in the merger, the Donlar shareholders (other than TFIC, Inc.,
Willis Stein/Star Polymers and Dr. Robert Martin, and excluding the additional
1.6 million shares to be issued to Tennessee Rural Health Improvement
Association) will own approximately 41.6% of the outstanding combined company
common stock and 9.4% on a fully diluted basis.

WHAT DR. ROBERT MARTIN, WILLIS STEIN & PARTNERS, L.P. AND STAR POLYMERS, L.L.C.
WILL RECEIVE AS A RESULT OF THE RESTRUCTURING PLAN (SEE PAGES 24-28)


     Willis Stein & Partners, L.P. and its affiliate, Star Polymers, L.L.C.,
will collectively receive senior convertible preferred stock of the combined
company with a stated liquidation value of $9.0 million and convertible into
approximately 13.23 million shares of common stock of the combined company in
exchange for $9.0 million of original principal amount of notes plus accrued
interest and will receive 1.0 million shares of common stock of the combined
company in exchange for approximately 20.3 million shares of Donlar preferred
stock. Dr. Martin will receive senior convertible preferred stock of the
combined company with a stated liquidation value of $9.0 million and convertible
into approximately 13.23 million shares of common stock of the combined company
in exchange for approximately $9.9 million of original principal amount of notes
plus accrued interest, will receive 5.0 million shares of common stock of the
combined company in exchange for the relinquishment of his rights to receive
royalty payments equal to one percent of all sales during a ten year period
beginning in 2000 and the cancellation of approximately 16.56 million shares of
Donlar common and preferred stock and will receive a warrant to purchase 3.0
million share of common stock of the combined company for $0.68 per share in
exchange for cancellation of existing options and warrants to purchase
approximately 38.4 million shares of Donlar common and preferred stock at
exercise prices ranging from $0.01 to $5.50. Dr. Martin will also receive
1,187,940 shares of combined company common stock in exchange for the 4,569,000
shares of Donlar Biosyntrex common stock that he owns based on the exchange rate
in the merger.


THE CONVERTIBLE LOANS (SEE PAGES 22-25 AND 26-27)

     Donlar Biosyntrex and Donlar are borrowers under a term loan agreement with
Tennessee Farmers Life Insurance Company pursuant to which they obtained a
bridge loan facility and restated certain previously existing secured loans. The
bridge loan facility is for up to $2.127 million (of which $1.786 million has
been drawn down) and will be convertible into shares of the combined company
common stock at a rate of one share per $0.29 of outstanding principal amount of
the loan. The restated loans are in the total amount of $19.2 million and will
be convertible into shares of the combined company common stock at a rate of one

                                        6


share per $0.68 of outstanding principal amount of the loans. The maximum number
of shares issuable upon conversion of the loans is approximately 34.4 million
which after completion of the restructuring including the merger would
constitute approximately 37.2% of the combined company common stock on a fully
diluted basis. As part of the restructuring, the combined company will issue
approximately 1.6 million shares of its common stock to Tennessee Rural Health
Improvement Association and approximately 3.85 million shares of Donlar common
stock owned by TFIC, Inc., an affiliate of Tennessee Farmers, will be cancelled
with no additional shares being issued in the merger.

THE 1998 AND 2000 NOTEHOLDERS (SEE PAGES 25-28)

     To further eliminate debt from the balance sheet of Donlar and Donlar
Biosyntrex, and after the merger, the combined company, Donlar has reached
agreements with the fifteen holders of approximately $1.9 million of original
principal amount of notes issued in 1998 and 2000 to exchange their notes for
shares of senior convertible preferred stock in an aggregate stated liquidation
value equal to the total amount of the notes and convertible into approximately
2.8 million shares of common stock of the combined company.

OWNERSHIP OF THE COMBINED COMPANY FOLLOWING THE COMPLETION OF THE RESTRUCTURING
PLAN, INCLUDING THE MERGER (SEE PAGE 26)


     As a result of the restructuring plan, which includes the merger, the
pre-merger Donlar shareholders (other than TFIC, Inc., Dr. Martin, Willis
Stein/Star Polymers, and excluding the additional 1.6 million shares being
issued to Tennessee Rural Health) will own approximately 41.6% and the
pre-merger shareholders of Donlar Biosyntrex (other than Donlar) will own
approximately 19.5% of the outstanding common stock of the combined company. On
a fully diluted basis, assuming conversion or exercise of all notes, preferred
equity, warrants and other securities of the combined company that are
convertible into or exercisable for shares of common stock of the combined
company, the pre-merger Donlar shareholders (other than TFIC, Inc., Dr. Martin,
Willis Stein/Star Polymers, and excluding the additional 1.6 million shares
being issued to Tennessee Rural Health) will own approximately 9.4%, the former
shareholders of Donlar Biosyntrex (other than Donlar and Dr. Martin) will own
approximately 4.4%, Tennessee Farmers will own approximately 37.2%, Willis
Stein/Star Polymers will own approximately 15.4% and Dr. Martin will own
approximately 22.9% of the combined company common stock (excluding the shares
he will receive upon conversion of the 4,569,000 shares of Donlar Biosyntrex
common stock that he owns).


INCLUSION OF SHARES OF DONLAR COMMON STOCK FOR TRADING ON THE NASD
OVER-THE-COUNTER BULLETIN BOARD

     Following the merger, the combined company will seek authorization for its
common stock to be traded on the NASD over-the-counter bulletin board and a
stock symbol for such trading.

IT IS NOT ANTICIPATED THAT THE COMBINED COMPANY WILL PAY DIVIDENDS FOLLOWING THE
MERGER

     Neither Donlar nor Donlar Biosyntrex has ever paid dividends on its common
stock. It is not anticipated that the combined company will pay dividends after
the merger.

THE TAX CONSEQUENCES OF THE MERGER ARE UNCERTAIN (SEE PAGE 45)

     The companies have not received a tax opinion regarding the federal income
tax consequences of the merger. The range of possible tax consequences is
described in this information statement/prospectus under the heading "Material
Federal Income Tax Consequences."

THERE ARE NO MATERIAL FEDERAL OR STATE REGULATORY REQUIREMENTS NECESSARY TO
CONSUMMATE THE MERGER

     There are no material federal or state regulatory requirements to be
complied with to consummate the merger. However, the merger will not be
effective until Donlar and Donlar Biosyntrex file articles of merger with the
Secretary of State of the State of Illinois and the State of Nevada.

                                        7


DONLAR BIOSYNTREX SHAREHOLDERS WILL HAVE APPRAISAL RIGHTS (SEE PAGE 31)

     Under the Nevada Revised Statutes, notwithstanding the approval of the
merger by the holders of the requisite number of shares of capital stock of
Donlar Biosyntrex, a Donlar Biosyntrex shareholder who, prior to the vote on the
merger, delivers a written notice to Donlar Biosyntrex of his or her intent to
demand payment for his shares if the merger is effectuated, who does not vote
his or her shares in favor of the merger and who otherwise strictly complies
with the requirements of Nevada law may be able to demand payment from Donlar
Biosyntrex for the fair value of his shares.

BOARD OF DIRECTORS AND MANAGEMENT OF THE COMBINED COMPANY FOLLOWING THE MERGER
(SEE PAGE 39)

     The boards of directors of Donlar and Donlar Biosyntrex are currently
identical. The companies' board of directors will continue as the board of
directors of the combined company.

     Larry P. Koskan, currently serving as president, chief executive officer
and chairman of the board of both Donlar and Donlar Biosyntrex, will be
president, chief executive officer and chairman of the board of the combined
company. Joel H. Lurquin, currently serving as controller, treasurer and
secretary of both Donlar and Donlar Biosyntrex, will be controller, treasurer
and secretary of the combined company. Robert P. Pietrangelo, currently serving
as a vice president and the chief operating officer of both Donlar and Donlar
Biosyntrex, will be a vice president and the chief operating officer of the
combined company.

COMPARATIVE PER SHARE MARKET PRICE INFORMATION (SEE PAGE 47)

     Shares of Donlar Biosyntrex common stock trade on the NASD over-the-counter
bulletin board on which bid and ask prices are quoted. Neither Donlar common
stock nor Donlar preferred stock is quoted or listed on any market or exchange.

DETERMINATION OF EXCHANGE RATIOS (SEE PAGES 26-29)


     The merger is a merger between Donlar Biosyntrex and Donlar, which is the
owner of approximately 68% of the outstanding common stock of Donlar Biosyntrex.
As a result of the negotiation of the restructuring plan by the companies,
Tennessee Farmers, Willis Stein & Partners, Dr. Martin and the 1998 and 2000
noteholders, it was agreed that 12.7 million shares of the combined company
common stock, representing approximately 61% of the shares on an outstanding
basis and 13.6% on a fully diluted basis, would be issued in the merger to the
Donlar and Donlar Biosyntrex shareholders (other than Donlar, Willis Stein/Star
Polymers and TFIC, Inc.). The 12.7 million shares is being allocated between the
Donlar and Donlar Biosyntrex shareholders on the basis of the respective
ownership of Donlar Biosyntrex common stock by Donlar on the one hand (i.e.,
68%) and all other shareholders of Donlar Biosyntrex on the other hand (i.e.,
32%). Therefore, the Donlar shareholders will receive 68% of the 12.7 million
shares, or 8.7 million shares, and the Donlar Biosyntrex shareholders (including
Dr. Martin's shares) will receive 32% of the 12.7 million shares, or 4.0 million
shares.


ACCOUNTING TREATMENT (SEE PAGE 45)

     Donlar intends to account for the merger on the "purchase" method of
accounting in accordance with SFAS 141, "Business Combinations." The transaction
will be treated as a transfer under common control for Donlar's 68% ownership of
Donlar Biosyntrex and as a purchase of minority interest for the remaining 32%.

WHEN WE EXPECT THE MERGER TO CLOSE

     We expect completion of the merger as soon as practicable following
approval of the merger by the shareholders of Donlar and Donlar Biosyntrex at
their respective special shareholders meetings and satisfaction of all other
conditions to the merger. Pursuant to an agreement entered into by Donlar and
Donlar Biosyntrex with their principal lender, Tennessee Farmers, they have
agreed to use their best efforts to complete the merger on or before July 7,
2002. Tennessee Farmers has agreed to extend the date for completion of the
merger until February 28, 2003.

                                        8


OUR REASONS FOR THE MERGER AND ADOPTION OF EQUITY INCENTIVE PLAN (SEE PAGE 35)

     The board of directors of Donlar and Donlar Biosyntrex have adopted a
restructuring plan which is fully described under "Proposal 1 -- Approval of the
Agreement and Plan of Merger -- Background of the Merger -- Restructuring Plan"
and "Proposal 1 -- Approval of the Agreement and Plan of Merger -- Determination
of the Terms of the Merger and Restructuring Plan." Under this plan, Donlar and
Donlar Biosyntrex have entered into a Bridge and Consolidated Term Loan
Agreement with the companies' principal lender, Tennessee Farmers. Tennessee
Farmers, as a condition of making the bridge loan and restructuring certain
existing loans to Donlar and Donlar Biosyntrex under the loan agreement,
required the merger be completed by July 7, 2002, unless such date is extended
by Tennessee Farmers. The date for completion of the merger has been extended
until February 28, 2003. Tennessee Farmers is requiring the merger and the
companies have agreed to use their best efforts to complete the merger because
it will simplify the companies' capital structure thereby reducing accounting
and legal costs and making the companies more attractive to potential investors
and lenders. In addition, since the bridge loan and the restructuring of the
existing Tennessee Farmers loans were necessary for the companies to continue in
operation, and Tennessee Farmers is requiring the merger as a condition of those
transactions, we believe that the merger is in the best interests of the
companies and their shareholders. In connection with the merger, the boards of
directors of Donlar and Donlar Biosyntrex believe that Donlar should adopt, and
the Donlar board of directors have adopted, an equity incentive plan, which is
fully described under "Proposal 2 -- Adoption of Donlar 2002 Equity Incentive
Plan," to provide the combined company greater flexibility in compensating
persons who contribute in the future to the successful operation and growth of
the combined company.

WE RECOMMEND THAT DONLAR BIOSYNTREX SHAREHOLDERS APPROVE THE AGREEMENT AND PLAN
OF MERGER AND APPROVE THE ADOPTION OF THE DONLAR 2002 EQUITY INCENTIVE PLAN (SEE
PAGE 35)

     The Donlar Biosyntrex board believes that the merger is fair to you and is
in your best interests, and, in accordance with Nevada law, unanimously
recommends that you vote FOR the proposal to approve the merger agreement.
Furthermore, the Donlar Biosyntrex board believes that the equity incentive plan
will provide the combined company greater flexibility in compensating persons
who contribute in the future to the successful operation and growth of the
combined company and, in accordance with Nevada law, unanimously recommends that
you vote FOR the proposal to approve the adoption of the Donlar 2002 Equity
Incentive Plan.

THE DONLAR BIOSYNTREX SPECIAL MEETING (SEE PAGE 19)

     Donlar Biosyntrex will hold its special meeting of shareholders at its
offices at 6502 South Archer Road, Bedford Park, Illinois 60501 on February   ,
2003 at 11:00 a.m. local time. Donlar Biosyntrex is required to send you a copy
of this information statement/prospectus at least 20 calendar days before its
special meeting.

                                        9


                                  RISK FACTORS

     The short and long term success of the combined company is subject to
certain risks, many of which are substantial in nature. Because Donlar now has
no operations and serves only as a holding company for the Donlar Biosyntrex
common stock that it owns, the combined company will be subject to substantially
the same risks as Donlar Biosyntrex prior to the merger. You should consider
carefully the following factors, in addition to other information contained in
this information statement/prospectus.

     Donlar Biosyntrex And Donlar Both Have A History Of Operating Losses And
May Never Become Profitable.  Both Donlar Biosyntrex and Donlar have incurred
significant net operating losses since their formations. As of September 30,
2002, Donlar, including the historical financial results of Donlar Biosyntrex,
had a shareholders' deficit of $36.2 million, a loss of approximately $6.8
million for the first three quarters of 2002 and an accumulated deficit of
$148.6 million. The factors contributing to these significant operating losses
include:

     - marketing expenditures;

     - acquisition expenses and costs;

     - expansion of research and development programs;

     - costs associated with pre-clinical studies and clinical trials;

     - nutritional studies;

     - regulatory compliance requirements;

     - trials for other products under development; and

     - implementation of programs to market products ultimately approved for
       distribution.

     Donlar Biosyntrex's, and after the merger, the combined company's, future
success and ability to achieve profitability depends upon its ability to
successfully operate its businesses. Neither Donlar Biosyntrex nor the combined
company may ever achieve significant revenues or profitable operations.

     Donlar's And Donlar Biosyntrex's Recurring Losses Raise Doubt About Their
Ability To Continue As A Going Concern.  The consolidated financial statements
of Donlar and Donlar Biosyntrex have been prepared on the assumption that Donlar
and Donlar Biosyntrex will continue as a going concern. Donlar's and Donlar
Biosyntrex's independent public accountants have issued their reports dated
April 5, 2002 that include an explanatory paragraph stating that Donlar's and
Donlar Biosyntrex's recurring losses and accumulated deficit, among other
things, raise substantial doubt about their ability to continue as a going
concern. Donlar's and Donlar Biosyntrex's historical sales are limited and it
has been necessary to rely upon financing from debt and the sale of equity
securities to sustain operations.

     If The Combined Company Cannot Satisfy Its Substantial Debt Obligations, It
Will Negatively Effect The Value Of Its Stock.  Donlar and Donlar Biosyntrex are
co-obligors under a loan agreement which covers a bridge loan facility totaling
up to $2.127 (of which $1.786 million has been drawn down) million and two prior
loans the terms of which were amended and restated in the loan agreement in the
amount of approximately $19.18 million. Each of the loans made or restated
pursuant to the loan agreement is subject to acceleration and the application of
higher default rates of interest in the event the combined company defaults in
the payment of principal or interest when due, breaches any covenants contained
in the loan agreement that are not remedied within five calendar days or any
other specified event of default occurs. The combined company may not be able to
comply with the covenants and events of default in the loan agreement, some of
which events of default are entirely beyond its control. Even if there are no
future defaults, principal and interest in the amount of approximately $2.02
million on the loans made under the bridge loan facility are due and payable on
March 18, 2003. In addition, approximately $1.34 million is due in March 2003 on
the restated loans. The combined company must either pay these amounts or
refinance them. The combined company may not have the resources to pay this debt
when it is due and the holder of the loans or another source may not be willing
to provide the resources to refinance the debt.

                                        10



     The Restructuring Plan Involves Substantial Dilution To
Shareholders.  Donlar currently owns 68% of the outstanding Donlar Biosyntrex
common stock and all other shareholders own 32% of the outstanding Donlar
Biosyntrex common stock. As part of the restructuring plan, 5.0 million, 1.0
million, approximately 1.6 million and 465,000 shares of the combined company
common stock will be issued to Dr. Martin, Willis Stein & Partners, Tennessee
Rural Health and collectively Messrs. Randy Olshen, Michael Acton, Rudy Monnich
and Charles Brodzki (each creditors of the companies), respectively. In
addition, a warrant will be issued to Dr. Martin for 3.0 million shares of the
combined company common stock, shares of the combined company convertible
preferred stock which are convertible into approximately 29.3 million shares of
combined company common stock will be issued to Dr. Martin, Willis Stein/Star
Polymers, and the 1998 and 2000 note holders, Tennessee Farmers Life Insurance
Company obtained notes in the aggregate amount of in excess of $21.0 million
that are convertible into approximately 34.4 million shares of the combined
company common stock and 5.0 million shares of combined company common stock
will be reserved for issuance under the equity incentive plan. As a result of
the foregoing transactions and completion of the merger, the pre-merger Donlar
shareholders (other than Dr. Martin, Willis Stein/Star Polymers, TFIC, Inc. and
the additional shares being issued to Tennessee Rural Health) will own
approximately 41.6% and the pre-merger Donlar Biosyntrex shareholders (other
than Donlar) will own approximately 19.5% of the outstanding combined company
common stock. On a fully diluted basis, assuming conversion or exercise of all
notes, preferred equity, warrants and other securities of the combined company
that are convertible into or exercisable for shares of common stock of the
combined company, the pre-merger Donlar shareholders (excluding Dr. Martin,
Willis Stein/Star Polymers and the additional 1.6 million shares being issued to
Tennessee Rural Health) will own approximately 9.4%, the pre-merger shareholders
of Donlar Biosyntrex (other than Donlar) will own approximately 4.4%, Tennessee
Farmers will own approximately 38.3%, Willis Stein/Star Polymers will own
approximately 15.4% and Dr. Martin will own approximately 22.9% of the combined
company common stock (excluding the shares he will receive upon conversion of
the 4,569,000 shares of Donlar Biosyntrex stock that he owns). The maximum
combined effect of the issuance of the shares of common stock, upon the exercise
of Dr. Martin's warrant, the conversion of the convertible preferred stock and
the conversion of the notes would be to increase the number of shares of
combined company common stock outstanding by approximately 67 million shares.


     If The Combined Company Sells Additional Equity Securities, It May Result
In Additional Shareholder Dilution.  The combined company may need to sell
additional equity securities or obtain other forms of financing to fund its
operations. The loan agreement prohibits the combined company from issuing
additional equity (except in accordance with the restructuring plan) or
incurring additional indebtedness (except indebtedness incurred under the loan
agreement, extensions or renewals of existing indebtedness as long as the
principal amount is not increased and capitalized leases not exceeded in the
aggregate $25,000) without the lender's approval. Absent such additional
financing, the combined company may find it necessary to postpone or cancel some
or all of its planned business activities. This postponement could adversely
affect the combined company's ability to conduct its business operations,
generate future revenues and introduce new products. Furthermore, additional
financing may not be available, or, if available, may not be available on
acceptable terms or in required amounts. If additional funds are raised by
issuing shares of common stock or securities convertible into common stock,
those sales or conversion could result in further and possibly substantial
dilution of the combined company's shareholders. Substantial dilution may make
it more difficult for investors to sell their shares or may result in a lower
price of the combined company's securities.

     The Trading Price Of The Combined Company's Common Stock Is Likely To Be
Volatile.  The trading price of Donlar Biosyntrex's common stock has been and,
in the future, of the combined company, is likely to continue to be subject to
wide fluctuations in response to the quarter to quarter variations in Donlar
Biosyntrex's, and, in the future, the combined company's operating results,
material announcements by Donlar Biosyntrex, the combined company or its
competitors, governmental regulatory action, conditions in the industries in
which they operate, or other events or factors, many of which are beyond Donlar
Biosyntrex's and the combined company's control. Since March 31, 2000, the
trading or high and low bid and ask price of Donlar Biosyntrex's common stock
has fluctuated from a high of $8.60 and a low of $0.05. The combined company's
operating results in future quarters may be below the expectations of investors.
In such event, the price of the common stock would likely decline, perhaps
substantially. In addition, the stock market has historically experienced
extreme price and volume fluctuations.

                                        11


     The Combined Company Is Unlikely To Pay Dividends.  Neither Donlar nor
Donlar Biosyntrex has ever declared or paid cash dividends on its common stock
and it is not anticipated that any cash dividends will be declared on the
combined company's common stock in the foreseeable future.

     If The Combined Company Is Not Successful In Commercializing Its Products,
It Will Not Be Able To Generate Enough Income To Cover Its Operating Expenses
And Debt Service.  Donlar was founded in 1990 to develop, manufacture and market
an entirely new protein technology with the potential to replace a generation of
older, non-biodegradable and potentially toxic chemicals. This new family of
biopolymers, know as thermal polyaspartates or TPA, is non-hazardous, non-toxic,
hypoallergenic, environmentally friendly and biodegradable. These proteins are
used in a broad range of industrial, agricultural and consumer markets. TPA
products are beta proteins (biopolymers) manufactured from the common biological
amino acid, L-aspartic acid. TPA is a highly active biopolymer that is
completely soluble in water. By varying the manufacturing method, different
properties can be built into the biopolymer, tailoring it to a specific use.
Products are formulated and packaged into both powder and liquid forms.

     Until 1996, Donlar was engaged principally in research and development
activities, and from 1996 through 2000, market development activities related to
several products utilizing TPA. These market development activities have been
continued by Donlar Biosyntrex since its acquisition of Donlar's businesses.
While marketing of the TPA products has commenced in the crop nutrition and oil
field service areas, the products have not achieved full commercialization, and
product applications are in various stages of commercialization. As a result,
the TPA products have been sold only in limited quantities and there can be no
assurance that a significant market will develop for such products with respect
to any of their potential applications. Donlar Biosyntrex's crop nutrition and
performance chemical products have been used commercially for only a short
period of time. Donlar Biosyntrex's current and the combined company's potential
customers in the agricultural, performance chemicals, and other fields in which
Donlar Biosyntrex's and, in the future, the combined company's products have
potential applications require predictable and consistent performance. Although
certain products incorporating the TPA technology have passed product
performance and reliability testing in both laboratory and commercial use, there
can be no assurance that they will continue to do so consistently in the future,
will meet future customer performance standards or will offer sufficient price
or performance advantages required to achieve commercial success. The combined
company's failure to develop, manufacture and commercialize TPA products on a
timely and cost effective basis will prevent it from generating enough revenues
to cover its operating expenses and debt service.

     If The Combined Company's Agricultural Customers Do Not Accept Its
Products, It Will Negatively Affect Revenues.  The combined company's future
success in agriculture depends largely on acceptance of the TPA technology by
agricultural customers and the ability of the combined company to educate those
customers about the proper methods and rates of application required to obtain
the levels of increased yield that the TPA products are capable of generating.
Traditionally, agricultural end users have been slow to adopt new technologies
until their consistent effectiveness and economic value have been evidenced over
several growing seasons. Successful introduction of the combined company's
products will also depend to a large extent on recommendations of prior users.
Although Donlar Biosyntrex's research data have shown that its crop nutrition
products result in increased yields, the level of such increase and, thus, the
economic return from use of such products, depends on the method and rate of
application, the type of crop and prevailing weather and soil conditions. There
can be no assurance that the combined company will be able to demonstrate that
the purchase of its crop nutrition products will be consistently cost effective
for the intended users.

     If The Combined Company Cannot Protect Its Proprietary Information, It May
Lead To Increased Competition And Expenses And Decreased Revenues.  The combined
company's success will depend, in part, on its ability to obtain patent
protection for the thermal polyaspartates processes, materials, and methods of
use, to preserve its trade secrets, and to operate without infringing the patent
or other proprietary rights of others. Donlar has been granted 48 United States
patents. Each time that Donlar filed a patent application in the United States,
it filed similar applications in foreign jurisdictions that Donlar believed were
important to its future business and that afford reasonable protection to
intellectual property rights. Donlar has been granted 92 foreign patents,
including patents granted by the European Community, South Africa, Israel,

                                        12


Japan, Mexico, Russia and Egypt, and currently has numerous patent applications
pending in such jurisdictions. The patent applications filed by Donlar may not
result in issued patents and the scope and breadth of any claims allowed in any
patents issued to Donlar, Donlar Biosyntrex or the combined company may not
exclude competitors or provide competitive advantages to the combined company.
In addition, any patents issued to Donlar, Donlar Biosyntrex or the combined
company may not be held valid if subsequently challenged, others may claim
rights in the patents and other proprietary technology owned by the combined
company, and others may have developed or will develop similar products or
technologies without violating any of the combined company's proprietary rights.

     The combined company's inability to obtain patent protection, preserve its
trade secrets or operate without infringing the proprietary rights of others, as
well as its loss of any rights to technology that it now has or acquires in the
future, could have a negative impact on its ability to maintain or increase
sales revenues. Litigation, which could result in substantial cost to, and
diversion of effort by, the combined company, may be necessary to enforce
patents owned by the combined company, to defend the combined company against
infringement claims made by others, or to determine the ownership, scope or
validity of the proprietary rights of the combined company and others. An
adverse outcome in any such litigation could subject the combined company to
significant liabilities to third parties, require it to seek licenses from third
parties, and/or require it to cease using certain technology, any of which could
increase its operating costs or negatively impact its ability to maintain or
increase sales.

     The combined company may also become involved in interference proceedings
declared by the United States Patent and Trademark Office in connection with one
or more of Donlar's, Donlar Biosyntrex's or, in the future, the combined
company's patents or patent applications to determine priority of invention. Any
such proceeding could result in substantial cost to the combined company, as
well as a possible adverse decision as to priority of invention of the patent or
patent application involved. In addition, the combined company may become
involved in reissue or reexamination proceedings in the patent office in
connection with the scope or validity of its patents. Any such proceeding could
have a material adverse effect on its business, results of operations and
financial condition, and an adverse outcome in such proceeding could result in a
reduction of the scope of the claims of any such patents or such patents being
declared invalid. In addition, from time to time, to protect its competitive
position, the combined company may initiate reexamination proceedings in the
patent office with respect to patents owned by others. Such proceedings could
result in substantial cost to, and diversion of effort by, the combined company,
and an adverse decision in such proceedings could increase its operating costs
or negatively impact its ability to maintain or increase sales revenues.

     Donlar Biosyntrex relies and, in the future, the combined company will
rely, on trade secrets and proprietary know how in the conduct of the its
operations. Donlar Biosyntrex uses employee and third party confidentiality and
non disclosure agreements to protect such trade secrets and know how. The
obligation to maintain the confidentiality of such trade secrets or proprietary
information may be breached by employees, consultants, advisors or others and
the combined company may not have adequate remedies for any breach. In addition,
the trade secrets or proprietary know how may otherwise become known or be
independently developed or discovered by third parties.

     The Combined Company May Not Be Able To Maintain Or Increase Sales Revenues
Due To Competition.  While Donlar Biosyntrex is not aware of any technology
directly competitive with its TPA products in the agricultural field, there are
numerous types of natural ingredients such as humates, alginates, heprins and
other amino acid extract products that act as fertilizers, plant growth
stimulants or immune system aids for which claims have been made regarding their
ability to increase plant yields. These products are marketed by numerous
regional distributors and sold to dealers, who, in turn, sell to farmers and
growers. In the performance chemicals field there is substantial competition by
other chemical products, principally water soluble polymers and similar products
manufactured by companies such as Rohm and Hass, BASF AG, Goodrich and others.
Bayer AG produces limited quantities of a technical grade, highly branched form
of a similar type product using production methods that are outside the scope of
Donlar's production patents. This product has applications that may be outside
the scope of Donlar's methods of use patents. All of these larger producers of
chemical products have substantially greater financial and technical resources,
larger research and development staffs, and greater manufacturing and marketing
capabilities than Donlar Biosyntrex and, in

                                        13


the future, the combined company. There can be no assurance that Donlar
Biosyntrex's and, in the future, the combined company's, performance chemicals
products will compete effectively against products produced by such competitors.

     The Combined Company's Limited Manufacturing Capacity and Experience May
Have A Material Adverse Effect On Its Results Of Operations.  The combined
company's success will depend, in part, on its ability to manufacture its
products in significant quantities, with consistent quality, at acceptable costs
and on a timely basis. The combined company has limited experience in high
volume manufacturing.

     If The Combined Company's Operation Of Its Manufacturing Facility Is
Materially Disrupted, It May Result In Significant Increased Costs And Reduced
Revenues.  The Peru, Illinois plant is Donlar Biosyntrex's and will be the
combined company's sole manufacturing facility and the only facility capable of
producing their products in quantities sufficient to meet its projected needs.
While Donlar Biosyntrex maintains and, in the future, it is expected that the
combined company will maintain, business interruption insurance in the amount of
$15 million, any material disruption in the Peru plant's operations, whether due
to fire, natural disaster or otherwise, and whether or not covered by that
insurance, could significantly increase operating costs and reduce revenues.

     Failure By The Combined Company To Obtain Or Maintain Regulatory Approval
For The Distribution Of Its Products In Key U.S. States Would Significantly
Limit Its Ability To Market Its Crop Nutrition Products.  In each of the fifty
states, the respective departments of agriculture have various requirements for
the registration of different types of agricultural products to be used within
that state. Donlar Biosyntrex's products do not require registration in 26
states. In the remaining 24 states, the purpose for registration is to assure
consumers/growers that the products can be used safely and that they have
demonstrated a variety of benefits such as protection against insects or root
growth enhancement. The state departments of agriculture that require
registration publish guide lines for the submission of several different kinds
of data in order to make a determination for registration. These data include
laboratory, green house, university and field test results, as well as toxicity,
environmental and general safety information. Each state has its own
requirements which range from minimal information coupled with a small fee to
extensive data sets that cover several years of experience and may be very
expensive to comply with. The review process may include several resubmissions
of updated data or other kinds of information and may take years. States may
also give limited registration to products that cover only one or more kinds of
plants.

     Donlar Biosyntrex's products have been registered in 20 of the 24 states
requiring registration, and the company is pursuing registration in the four
other states, South Dakota, Alabama, Mississippi and Pennsylvania. When the
department of agriculture of a specific state registers the products, those
products may then be sold with required information that is printed on the
product's label such as the plants/crops that the product can be used on,
instructions on how to safely apply the product, maximum quantities to use and a
variety of safety and toxicity handling precautions.

     Donlar Biosyntrex's products are also subject to approval by foreign
regulatory authorities, but there are no federal regulatory approvals required
for distribution. A loss of a product registration in a key U.S. state would
significantly limit the combined company's ability to market its crop nutrition
products.

     If The Technology Relied Upon By The Combined Company Fails To Remain
Competitive, It Will Not Be Able To Increase Or Maintain Sales
Revenues.  Although Donlar has developed 50 patents covering manufacturing
processes, composition and methods of use, all of Donlar Biosyntrex's products
are based on its patented TPA technology. The earliest patent for the TPA
technology was issued in 1991 and will expire in 2008 and relates to the initial
manufacturing process. The latest patent was issued in 2002 and, under the new
patent law, will expire in 2022. The fields in which Donlar Biosyntrex, and in
the future, the combined company, intend to sell their products are highly
competitive and intensive research and development is always being undertaken by
governmental entities, educational institutions and private enterprises with
respect to products having practical effects such as those of certain of Donlar
Biosyntrex's products. Competitive products may be introduced by third parties
or competing materials based on different or new technologies may become
commercially available. The combined company's competitors may succeed in
developing or marketing materials, technologies or products that exhibit
superior performance or are more commercially

                                        14


desirable or more cost effective than those developed and marketed by the
combined company. Any of the foregoing could have a negative affect on the
combined company's ability to maintain or increase sales revenues without
improving its products, developing new products or reducing costs.

     The Combined Company's Limited Experience In Marketing TPA Products May
Have A Negative Impact On Its Ability To Increase Sales Revenues.  While the
combined company's sales force has experience in marketing products to
agricultural and performance chemicals end users, the combined company has
limited experience in marketing and selling the thermal polyaspartates products.
To market its products effectively, the combined company will be required to
develop an expanded marketing and sales force that can effectively demonstrate
the advantages of, and recommended methods and rates of application for, the TPA
product applications. The crop nutrition products will also rely heavily on the
availability of recommendations of prior users. In the performance chemicals
field, Donlar Biosyntrex currently sells certain of its TPA products to
companies that typically blend its TPA products as an ingredient with their own
products and then sell the resulting blended product to other companies. The
combined company's future success will depend in part on the continued
relationships with distributors, its ability to enter into other similar
arrangements, the continuing interest of the existing distributors in current
and potential product applications and, eventually, the distributors' success in
marketing and willingness to purchase the combined company's products.

     Currently, Donlar Biosyntrex has no formal purchasing arrangements or
contracts with customers or distributors. The ordering process for the company's
products begins with the customer submitting a purchase order to Donlar
Biosyntrex's customer service department. The purchase order states the terms of
the purchase, such as price, quantities, freight terms and shipping dates. When
the purchase order is approved by management, it is confirmed back to the
customer, and the order is filled.

     Loss of Key Personnel By The Combined Company Would Have A Material Adverse
Effect On Its Business Operations.  Donlar Biosyntrex's principal executive
officers, Larry Koskan and Robert Pietrangelo, have an average of over 25 years
of collective experience in chemicals research, development and sales. The loss
of the services of either one of these executive officers or other key
personnel, or the failure of the combined company to attract and retain other
skilled and experienced personnel on acceptable terms, would have a material
adverse effect on the combined company's business operations. There is no key
person insurance on either of these executive officers. Both of these executive
officers have employment agreements with the company. Mr. Koskan's contract
expires on July 1, 2003 and Mr. Pietrangelo's expires on September 7, 2003,
unless extended.

     Because The Combined Company Has A Relatively Small Group Of Customers, The
Loss Of Any Single Customer May Have A Material Adverse Effect On Its Results Of
Operations, Financial Condition And Business.  Donlar Biosyntrex began
commercial sales of its products in 1999. Donlar Biosyntrex sells its crop
nutrition products primarily to agricultural distributors and its performance
chemicals products to chemical service companies. While the combined company
expects to significantly increase its sales in these product lines and to focus
its sales efforts on a more specifically targeted group of agriculture and
chemical distributors, sales may continue to be concentrated among a relatively
small group of customers, though not necessarily those that represented the
largest portions of Donlar Biosyntrex's sales in the past. In 2001, Donlar
Biosyntrex's top three customers based on net sales revenues, Industri Kapital,
Baker Hughes Incorporated and Clariant International, Ltd., Switzerland
accounted for 23.6%, 21.6% and 12.7% of its net sales revenues, respectively.
The loss of any one of these customers would have a material adverse effect on
the combined company, its results of operations and its financial condition.

     Because The Combined Company's Crop Nutrition Business Is Seasonal, Its
Results Of Operations May Vary Significantly From Quarter To Quarter.  Demand
for Donlar Biosyntrex's crop nutrition products can be expected to be
significantly affected by agricultural conditions, which can be unpredictable
and volatile as a result of a number of factors. The most important factors are
weather conditions and patterns, current and projected grain stocks and prices,
and governmental agricultural policies, including those that directly or
indirectly influence the number of acres planted, the level of grain stocks, the
mix of crops planted, and crop

                                        15


prices. Because of its dependence on agricultural markets, the crop nutrition
business is seasonal and the combined company's operating results may vary
significantly from quarter to quarter.

     New Environmental Or Other Regulations Could Increase The Combined
Company's Operating Costs. Like other manufacturers, Donlar Biosyntrex is
subject to a broad range of Federal, state, local and foreign laws and
requirements, including those governing discharges in the air and water, the
handling and disposal of solid and hazardous substances and wastes, the
remediation of contamination associated with the release of hazardous
substances, work place safety and equal employment opportunities. Donlar and
Donlar Biosyntrex have made expenditures to comply with such laws and
requirements. Donlar Biosyntrex believes, based on information currently
available to management, that it is in compliance with applicable environmental
and other legal requirements and that the combined company will not require
material capital expenditures to maintain compliance with such requirements in
the foreseeable future.

     Governmental authorities have the power to enforce compliance with such
laws and regulations, and violators may be subject to penalties, injunctions or
both. Third parties may also have the right to enforce compliance with such laws
and regulations. As the combined company develops new formulations for thermal
polyaspartates products and combines TPA with other products, such as herbicides
and insecticides, those products may become subject to additional review and
approval requirements governing the sale and use of its products. Donlar
Biosyntrex's manufacturing processes do not currently result in the generation
of hazardous wastes. This may not always be the case and material costs or
liabilities may be incurred by the combined company in the future as a result of
the manufacturing operations. It is also possible that other developments, such
as additional or increasingly strict requirements of laws and regulations of
these types, or enforcement policies thereunder, could significantly increase
the combined company's costs of operations.

     Personal Injury Or Property Damage Claims Relating To The Combined
Company's Products Could Have A Material Adverse Effect On Its Results of
Operations And Financial Condition.  Products sold by the combined company may
expose it to potential liability for personal injury or property damage claims
relating to the use of those products, particularly if used in a manner not in
conformity with the combined company's instructions. Although product liability
claims historically have not had a material adverse effect on Donlar or Donlar
Biosyntrex, the combined company may be subject to or incur liability for such
claims in the future. Although Donlar Biosyntrex maintains and, in the future,
the combined company will maintain, product liability insurance in amounts that
management deems commercially reasonable, a significant claim that is uninsured
or partially insured could result in loss or deferral of revenues, diversion of
resources, or damage to the combined company's reputation, any of which could
have a material adverse effect on the combined company's business, operating
results, and financial condition.


     The Officers and Directors Of Donlar And Donlar Biosyntrex Have Potential
Conflicts Of Interest In The Transaction.  The officers and members of the
Boards of Directors of Donlar and Donlar Biosyntrex are identical. The officers
and members of the Boards of Directors of Donlar and Donlar Biosyntrex will
serve as the members of the Board of Directors of the combined company. Dr.
Martin serves on both boards, will serve on the board of the combined company
and will receive interests in the combined company that are different from the
interests to be received by the Donlar and Donlar Biosyntrex shareholders
generally. In particular, Dr. Martin will receive senior convertible preferred
stock of the combined company with a stated liquidation value of $9.0 million
and convertible into approximately 13.23 million shares of common stock of the
combined company in exchange for approximately $9.9 million of original
principal amount of notes plus accrued interest, will receive 5.0 million shares
of common stock of the combined company in exchange for the relinquishment of
his rights to receive royalty payments and for approximately 16.5 million shares
of Donlar common and preferred stock and will receive a warrant to purchase 3.0
million shares of common stock of the combined company for $0.68 per share in
exchange for cancellation of existing options and warrants to purchase
approximately 38.4 million shares of Donlar common and preferred stock. Dr.
Martin will also receive 1,187,940 shares of combined company common stock in
exchange for the 4,569,000 shares of Donlar Biosyntrex common stock that he
owns. The boards did not seek a fairness determination with respect to the
merger and the related transactions. You should be aware of these potential
conflicts when considering the approval of the merger agreement and the equity
incentive plan by the boards.


                                        16


     If The Restructuring Plan Constitutes A Change Of Control Under The Change
Of Control Agreements With The Two Principal Executive Officers, Substantial
Benefits Could Be Payable Under Such Agreements At Some Time In The
Future.  Donlar has change of control agreements with its two principal
executive officers, Larry Koskan and Robert Pietrangelo, which provide that if
there is a change of control of Donlar and the executive officer is subsequently
terminated without cause or resigns for good reason within the applicable time
periods provided in the agreements, the executive officer would be entitled to
substantial severance benefits. Under the agreements, the approval of a plan of
merger by the Donlar shareholders may be deemed to constitute a change of
control. Mr. Koskan has waived any rights he may have under his agreement as a
result of the merger. Mr. Pietrangelo has declined Donlar's request for a
similar waiver. In the event the merger constitutes a change of control and Mr.
Pietrangelo is terminated without cause or resigns for good reason within the
applicable time periods provided for in his change of control agreement, based
on his current salary, Mr. Pietrangelo would be entitled to benefits currently
valued by Donlar at approximately $670,000.

     The Tax Consequences Of The Merger To Shareholders Are Uncertain And Could
Be Adverse.  The material U.S. federal income tax consequences of the merger are
uncertain and could be adverse. No tax opinion will be issued by Donlar
Biosyntrex's tax advisors prior to the consummation of the merger as to the
material federal income tax consequences of the merger. Donlar Biosyntrex has
not yet filed its federal income tax returns for the taxable years 2000 and 2001
and does not have available the necessary information for its tax advisors to
render an opinion on the federal income tax consequences of the proposed merger.
Once these tax returns are filed and additional information is gathered, Donlar
will seek an opinion on the federal income tax consequences of the merger from
its tax advisors. If such an opinion is obtained, copies will be made available
to shareholders.

                     THE DONLAR BIOSYNTREX SPECIAL MEETING

WHEN AND WHERE THE DONLAR BIOSYNTREX SPECIAL MEETING WILL BE HELD

     Donlar Biosyntrex will hold a special meeting of shareholders at its
offices at 6502 South Archer Road, Bedford Park, Illinois 60501 on February   ,
2003 at 11:00 a.m. local time. Donlar Biosyntrex is required to send you a copy
of this information statement/prospectus at least 20 calendar days before its
special meeting.

WHAT WILL BE VOTED ON AT THE DONLAR BIOSYNTREX SPECIAL MEETING

     Shareholders will consider and vote upon a proposal to approve the
Agreement and Plan of Merger dated as of June 7, 2002, between Donlar and Donlar
Biosyntrex and, in connection with the merger, a proposal to approve the
adoption of the Donlar 2002 Equity Incentive Plan. Under the merger agreement,
among other things:

     - Donlar Biosyntrex will merge with Donlar, with Donlar being the surviving
       corporation;

     - the articles of incorporation of Donlar will be the articles of
       incorporation of the combined company and will be amended to increase the
       number of authorized shares of capital stock from 60,000,000 shares of
       common stock and 38,000,000 shares of preferred stock to 200,000,000
       shares of common stock and 100,000,000 shares of preferred stock;

     - the outstanding shares of Donlar Biosyntrex common stock (other than
       those owned by Donlar) and Series A and Series B preferred stock will
       convert into the right to receive approximately 4.0 million and 21,000
       shares of common stock, respectively, of the combined company upon
       completion of the merger ;

     - the outstanding shares of Donlar common stock and preferred stock (other
       than those owned by TFIC, Inc., Dr. Robert Martin, Willis-Stein &
       Partners and its affiliate Star Polymers) will convert into the right to
       receive approximately 1.4 million and 7.3 million shares of common stock,
       respectively, of the combined company upon completion of the merger; and

     - the board of directors of the combined company will consist of the
       current members of the Donlar board.

     The equity incentive plan will be effective upon approval by the
shareholders and consummation of the merger. The equity incentive plan contains
essentially the same terms as the Donlar Biosyntrex 2001 Equity Incentive Plan.
It will authorize an aggregate of 5.0 million shares of Donlar common stock to
be used for awards to directors, management, employees and consultants of the
combined company and its subsidiaries.

     We may take action on the above matters at the Donlar Biosyntrex special
meeting on February   , 2003, or any later date to which the special meeting is
postponed or adjourned.

     The Donlar Biosyntrex board is unaware of other matters to be voted on at
the Donlar Biosyntrex special meeting.

SHAREHOLDERS ENTITLED TO VOTE

     Donlar Biosyntrex has set January 10, 2003 as the record date to determine
which Donlar Biosyntrex shareholders will be entitled to vote at the Donlar
Biosyntrex special meeting. Only Donlar Biosyntrex shareholders at the close of
business on January 10, 2003, will be entitled to receive notice of and to vote
at the Donlar Biosyntrex special meeting. As of the record date there were
48,816,622 issued and outstanding shares of Donlar Biosyntrex common stock. In
addition, Donlar Biosyntrex's records indicate that as of the record date there
were 39,124 issued and outstanding shares of Donlar Biosyntrex Series A
preferred stock convertible into 449 shares of Donlar Biosyntrex common stock.
Each holder of Donlar Biosyntrex's common stock on the record date is entitled
to one vote per share. Each holder of Donlar Biosyntrex Series A preferred stock
on the record date is entitled to one vote per share of common stock into which
such holder's Series A preferred stock is convertible. The holders of Donlar
Biosyntrex common stock and Series A preferred stock

                                        18


vote together as a single class. Shareholders may cast their votes in person or
by properly executed proxy. However, Donlar Biosyntrex is not soliciting proxies
and asks that you not send us one. If you wish to vote by proxy, you must
properly designate a proxy in accordance with Nevada law and your proxy must
attend the meeting and vote your shares.

     The holders of Donlar Biosyntrex Series A preferred stock are entitled to
vote as a separate class in connection with any merger of Donlar Biosyntrex
which would adversely affect the powers, preferences or rights of the Series A
preferred stock and therefore they are entitled to vote as a separate class on
the merger.

     Donlar, which owns approximately 33,279,520 shares of Donlar Biosyntrex
common stock constituting approximately 68% of the issued and outstanding Donlar
Biosyntrex common stock and 68% of the voting interest in Donlar Biosyntrex, has
agreed that it will vote in favor of adoption of the merger agreement and the
approval of the adoption of the Equity Incentive Plan.

VOTE REQUIRED TO ADOPT THE MERGER AGREEMENT AND APPROVE THE ADOPTION OF THE
EQUITY INCENTIVE PLAN

     The affirmative vote, either in person or by proxy, of a majority of the
issued and outstanding common stock and Series A preferred stock, on an as
converted basis, voting as a single class, is required to approve the merger
agreement and approve the adoption of the Equity Incentive Plan. The merger must
also be approved by a majority of the outstanding shares of Series A preferred
stock voting as a separate class. Donlar Biosyntrex has written agreements with
Dr. Kamal Modir, Peter LeDonne, Jr. and Kenneth Hubbard, collectively owning or
controlling a majority of the outstanding shares of Series A preferred stock,
providing that such holders will (a) exchange their Series A preferred stock for
combined company common stock on the basis of one share of combined company
common stock for each share of originally issued Series A preferred stock (i.e.,
excluding dividend shares) and (b) vote for approval of the merger agreement and
the related transactions.

     Abstentions and broker non-votes on the proposal to adopt the merger
agreement and the proposal to approve the adoption of the equity incentive plan
will effectively count as votes against the proposals.

VOTING YOUR SHARES

     The Donlar Biosyntrex board is not soliciting proxies from the Donlar
Biosyntrex common shareholders because Donlar owns 68% of the outstanding common
stock of Donlar Biosyntrex and Donlar Biosyntrex has reached agreements with the
holders of a majority of the outstanding Series A preferred stock to vote for
approval of the merger agreement and the related transactions. However, Donlar
Biosyntrex will hold a special meeting on February   , 2003, at which you may
vote on the proposals to adopt the merger agreement and approve the adoption of
the equity incentive plan. In order to vote at the special meeting, you must
either attend in person or vote through a duly appointed proxy. If you do not
either vote by proxy or attend the special meeting and vote in person, your vote
will be counted as not present for quorum purposes and will effectively count as
a vote against the proposal to adopt the merger agreement and against the
proposal to approve the adoption of the equity incentive plan.

     If you wish to vote by proxy, you must properly designate a proxy in
accordance with Nevada law and your proxy must attend the meeting and vote your
shares. If you attend the Donlar Biosyntrex special meeting in person, you may
vote your shares by completing a ballot at the meeting.

ESTABLISHING A QUORUM OF SHAREHOLDERS

     If a majority of the total number of votes entitled to be cast at the
special meeting are present at the special meeting, either in person or by
proxy, the special meeting will have the quorum of shareholders required to
transact business.

                                        19


INDEPENDENT AUDITORS TO BE PRESENT AT THE SPECIAL MEETING

     Representatives of Grant Thornton LLP, Donlar Biosyntrex's independent
auditors, will be present at the Donlar Biosyntrex special meeting and will have
the opportunity to make a statement if they desire to do so and be available to
respond to appropriate questions.

APPROVAL AND RECOMMENDATION BY DONLAR BIOSYNTREX BOARD

     The Donlar Biosyntrex board has unanimously approved the merger agreement,
the merger and the related matters including the adoption of the equity
incentive plan. The Donlar Biosyntrex board believes that the merger agreement,
the merger and the related matters are in the best interests of Donlar
Biosyntrex and, as required by Nevada law, recommends the Donlar Biosyntrex
shareholders vote "FOR" adoption of the merger agreement and "FOR" the approval
of the adoption of the Equity Incentive Plan. See "Proposal 1 -- Adoption of the
Merger Agreement -- Recommendation of the Donlar Biosyntrex Board and Donlar
Biosyntrex's Reasons for the Merger" and Proposal 2 -- Approval of the Adoption
of the Donlar 2002 Equity Incentive Plan."

           PROPOSAL 1 -- APPROVAL OF THE AGREEMENT AND PLAN OF MERGER

     The following summary describes the material background and terms and
provisions of the Agreement and Plan of Merger and the merger. We have attached
a copy of the merger agreement to this information statement/prospectus as
Appendix A and we have incorporated it into this information
statement/prospectus by reference. We urge all shareholders to read the merger
agreement carefully in its entirety. We qualify this summary in its entirety by
reference to the merger agreement.

BACKGROUND OF THE MERGER -- RESTRUCTURING PLAN

     In early 2001, as a result of anticipated difficulties in servicing debt
and obtaining necessary additional funding, management of Donlar and Donlar
Biosyntrex began to consider debt restructuring alternatives and sources of
additional funding. In May 2001, management of the companies met with Tennessee
Farmers Life Insurance Company, Willis Stein & Partners and Dr. Robert Martin,
the companies' three largest creditors, to discuss a restructuring plan. The
plan would have, in part, involved the merger of the companies to simplify the
corporate structure. In addition, the plan would have involved the conversion of
$27.0 million of the debt owed to the three creditors ($9.0 million each) in
exchange for preferred stock convertible into approximately 80% of the common
stock of the combined company.

     Subsequent to the meeting in May 2001, management of the companies and the
three creditors engaged in protracted negotiations concerning the terms of the
restructuring. While these negotiations took place, management continued to
explore alternatives for raising additional capital. Management engaged the
services of an investment advisor to assist them in finding sources of private
equity financing and/or a merger partner. Ultimately, management was unable to
find any sources of private equity financing on acceptable terms or any
appropriate merger partner.

     Because sources of private equity financing were not available on
acceptable terms, management sought additional debt financing from Tennessee
Farmers. As discussed in more detail below, Tennessee Farmers ultimately agreed
to provide $2.127 of bridge financing. However, such bridge financing was only
made available as part of the overall restructuring of the companies discussed
in detail below. Tennessee Farmers would not agree to convert any portion of its
debt into convertible preferred stock and, as a condition of the restructuring,
required the issuance of common stock to Tennessee Rural Health Improvement
Association. As discussed in detail below, the companies did reach agreement
with Willis Stein & Partners and Dr. Martin to exchange all of their debt
(exceeding $18.0 million) for convertible preferred stock plus shares of common
stock and, in the case of Dr. Martin, a warrant for the purchase of common
stock.

                                        20


     The specific terms of the restructuring plan include the following:

     As part of the restructuring plan, on March 18, 2002, Donlar Biosyntrex and
Donlar entered into a Bridge and Consolidated Term Loan Agreement with Tennessee
Farmers Life Insurance Company. Pursuant to the terms of the loan agreement,
Donlar Biosyntrex and Donlar obtained a bridge loan facility in the amount of
approximately $2.127 million to be used to refinance certain short term debt,
provide working capital, pay certain accounts payable creditors and pay expenses
of the transaction. As of December 6, 2002, approximately $1.79 million of the
bridge loan had been drawn down. In addition, the terms of existing loans to
Donlar in the original principal amount of approximately $17.64 million were
restated and made the joint and several obligation of Donlar and Donlar
Biosyntrex in the total amount of $19.2 million reflecting the original amount
of the loans and accrued, unpaid interest thereon. Each of the loans is
collateralized by substantially all of the assets of Donlar Biosyntrex and
Donlar.

     Loans under the bridge loan facility bear interest at a rate of eleven
percent per annum with one half of such interest payable on a quarterly basis on
the last business day of March, June, September and December and the other half
payable at maturity on March 18, 2003.

     The restated loans are divided into two loans. The first such loan is in
the principal amount of approximately $10.18 million, bears interest at a rate
of nine percent per annum until March 18, 2003, at which time such interest is
payable, and thereafter bears interest at eleven percent per annum payable on a
quarterly basis on the last business day of March, June, September and December.
The principal balance of the loan is payable in equal quarterly installments of
not less than $222,500 commencing on March 31, 2003 and thereafter on the last
business day of March, June, September and December. Any remaining unpaid
principal and interest is payable on March 31, 2007. The second such loan is in
the principal amount of $9.0 million, bears interest at a rate of one percent
per annum but neither interest nor principal are payable until the first to
occur of one of certain events described in the loan agreement, the latest of
which is March 18, 2005, after which time the interest that has accrued is
payable in full within thirty days and thereafter is payable quarterly on the
last business day of March, June, September and December together with principal
payments of not less than $222,500. Any remaining unpaid principal and interest
is payable on March 31, 2007.

     As a condition of the loans and as part of the restructuring plan, the
combined company will issue approximately 1.6 million shares of common stock to
Tennessee Rural Health Improvement Association, which will represent
approximately 7.8% of the outstanding combined company common stock and 1.8% on
a fully diluted basis. These shares are in addition to the approximately 1.27
million shares of combined company common stock to be issued to Tennessee Rural
Health in the merger in exchange for the approximately 2.6 million shares of
Donlar common stock currently owned by it. Tennessee Rural Health is a provider
of health insurance and other health benefits. It is affiliated with Tennessee
Farm Bureau Federation which owns approximately 7.5% of Tennessee Farmers.

     TFIC, Inc., an affiliate of Tennessee Farmers, will surrender for
cancellation in the merger, without issuance to it of any shares in the combined
company, approximately 3.85 million shares of Donlar common stock.

     As part of the restructuring plan and as permitted by the loan agreement,
the combined company will issue 465,000 shares of common stock to four
creditors, Mr. Randy Olshen, Mr. Michael Acton, Mr. Rudy Monnich and Mr. Charles
Brodzki, in exchange for their forgiveness of all debts and claims by them
against either Donlar or Donlar Biosyntrex.

     Mr. Olshen has a sales contract entitling him to a 20% commission on sales
of certain of Donlar Biosyntrex's products. Mr. Olshen has agreed to the
termination of that contract in exchange for 80,000 shares of combined company
common stock. While there is no current market for the combined company common
stock, based on the average of the bid and ask prices for the Donlar Biosyntex
common stock as reported on the NASD over-the-counter bulletin board on December
4, 2002 ($0.135), the shares to be issued to Mr. Olshen are estimated to be
worth approximately $10,800. During 2001 and 2002, Mr. Olshen was paid by Donlar
Biosyntrex a total of $27,724 in commissions under his sales contract.

                                        21


     Mr. Acton has a consulting contract entitling him to a consulting fee of
approximately $123,000. Mr. Acton has agreed to exchange the approximately
$94,000 remaining due under that contract for 200,000 shares of combined company
common stock.

     Mr. Monnich has an outstanding account payable of approximately $11,000 and
Mr. Brodzki has an outstanding note payable of approximately $50,000. They have
agreed to forgive these amounts in exchange for 60,000 and 125,000 shares of
combined company common stock, respectively. Each of the foregoing agreements
was reached as a result of individual negotiations. The market value of the
shares to be issued cannot be determined at this time because no market
currently exists for them.

     As a further condition of the loans, Donlar Biosyntrex and Donlar have
agreed to use their best efforts to complete the merger on or before July 7,
2002. At the request of the companies, Tennessee Farmers has agreed to extend
the date for completion of the merger to February 28, 2003. Failure to complete
the merger by February 28, 2003, or such later date as agreed to by Tennessee
Farmers, is an event of default which gives Tennessee Farmers the right to
declare the indebtedness under the loan agreement immediately due and payable.

     Donlar Biosyntrex and Donlar made numerous representations, warranties and
covenants in the loan agreement. Among the covenants, Donlar Biosyntrex and
Donlar agreed to limit their ability to incur additional indebtedness, make any
investments or loans, pay dividends, purchase, redeem or issue capital stock or
sell or encumber assets. Each of the loans made or restated pursuant to the loan
agreement is subject to acceleration and the application of higher default rates
of interest in the event Donlar Biosyntrex or Donlar defaults in the payment of
principal or interest when due, breaches any covenants contained in the loan
agreement that are not remedied within five calendar days or any other specified
event of default occurs.

     Each of the loans under the loan agreement is convertible at the option of
the lender at any time prior to repayment into common stock of Donlar Biosyntrex
and, subsequent to the merger, common stock of the combined company. Loans made
under the bridge loan facility convert at a rate of one share per $0.29 of
outstanding principal amount of the loans. The restated loans convert at a rate
of one share per $0.68 of outstanding principal amount of the loans. The maximum
number of shares of combined company common stock issuable upon conversion of
the loans is approximately 34.37 million. The conversion rates are subject to
antidilution protection. The holders of the loans have certain registration
rights with respect to the shares issuable upon conversion.

     As part of the restructuring plan, Donlar has also reached agreements with
Willis Stein & Partners and its affiliate Star Polymers to (i) exchange $9.0
million of original principal amount of notes plus accrued interest for shares
of a new series of senior convertible preferred stock of the combined company
with a stated liquidation value of $9.0 million and convertible into
approximately 13.23 million shares of common stock of the combined company and
(ii) exchange all of the Donlar equity securities held by Willis Stein/Star
Polymers, equaling approximately 20.28 million shares of Donlar common and
preferred stock, for 1.0 million shares of common stock of the combined company.
Willis Stein/Star Polymers will not receive any other common stock of the
combined company as a result of the merger. The obligation of Willis Stein/Star
Polymers to complete the foregoing exchanges is subject to the conditions that
Donlar amend its certificate of incorporation to contain the terms of the senior
convertible preferred, Donlar and Donlar Biosyntrex obtain the requisite
consents and approvals for the exchanges and the amendment to Donlar's
certificate of incorporation, Dr. Martin complete the exchanges described below
and the 1998 and 2000 note holders complete the exchanges described below.
Willis Stein & Partners agreed to vote its shares of voting stock of Donlar in
favor of the merger.

     Donlar has also reached agreement with Dr. Robert Martin, a director of
Donlar and Donlar Biosyntrex, to (i) exchange approximately $9.9 million of
original principal amount of notes plus accrued interest for shares of senior
convertible preferred stock with a stated liquidation value of $9.0 million and
convertible into approximately 13.23 million shares of the combined company's
common stock, (ii) relinquish rights to receive royalty payments from Donlar and
Donlar Biosyntrex equal to one percent of all sales during a ten year period
beginning in 2000 and surrender for cancellation all of the Donlar common and
preferred stock held by him, equaling approximately 16.56 million shares, in
exchange for 5.0 million shares of the common stock of the

                                        22



combined company and (iii) surrender for cancellation options and warrants to
purchase over 38 million shares of Donlar common and preferred stock at exercise
prices ranging from $0.01 to $5.50 for a warrant to purchase 3.0 million shares
of the common stock of the combined company for $0.68 per share. Dr. Martin will
also receive 1,187,940 shares of combined company common stock in the merger in
exchange for the 4,569,000 shares of Donlar Biosyntrex common stock that he
owns. Dr. Martin also agreed to vote his shares of voting stock of Donlar in
favor of the merger.


     Dr. Martin's right to receive royalties is contained in a management
consulting agreement with Donlar. The agreement provides that Dr. Martin will
provide consulting services to Donlar, not to exceed 60 hours without his
consent in any 12 month period, in return for royalties of one percent of all
sales of products during the term of the agreement. The agreement commenced on
April 1, 2000 and expires April 15, 2010. Royalty payments are to be made on
April 15 of each year during the term. Royalties of $46,219 accrued under the
agreement through June 30, 2002, but to date no royalties have been paid.

     To further eliminate debt from the balance sheet of Donlar and Donlar
Biosyntrex, and after the merger, the combined company, Donlar has reached
agreements with all fifteen holders of approximately $1.9 million of original
principal amount of notes issued in 1998 and 2000 to exchange their notes for
shares of senior convertible preferred stock in an aggregate stated liquidation
value equal to the total amount of the notes and convertible into approximately
2.8 million shares of common stock of the combined company. For additional
information about the restructuring plan, see "Determination of Terms of the
Merger and Restructuring Plan" immediately below and "Pro Forma Financial
Information."

     The companies as of September 30, 2002, had approximately $48.92 million of
liabilities. The restructuring including the merger will eliminate approximately
$25.26 million of liabilities, substituting for it approximately $20 million of
senior convertible preferred stock and 465,000 shares of common stock. It is
expected that the combined company will have approximately $23.66 million of
liabilities after completion of the merger and related transactions.

     As stated above, the terms of the merger and restructuring plan were
developed through negotiation beginning in May 2001 with Donlar's principal
lenders: Tennessee Farmers Life Insurance Company,


                                        25


Dr. Robert Martin and Willis Stein & Partners. It was agreed that Tennessee
Farmers would restructure Donlar's indebtedness to it, as described above, and
that the restructured indebtedness would be convertible into common stock of the
combined company following the merger at the rate of $0.68 per share, which
represented the approximate market value of the common stock of Donlar
Biosyntrex in late June 2001, when an initial understanding was reached on the
terms of the restructuring plan. As part of the plan, Dr. Martin and Willis
Stein/Star Polymers agreed to exchange their debt in Donlar in the respective
principal amounts of $9.9 million and $9.0 million plus accrued interest for
combined company senior convertible preferred stock, which is convertible at the
rate of $0.68 per share into combined company common stock. It was further
understood that as a result of the foregoing transactions, Tennessee Farmers,
Dr. Martin and Willis Stein/Star Polymers would own, on a fully diluted basis,
in the aggregate approximately eighty percent of the common equity of the
combined company. The remaining twenty percent would be issued to the holders of
Donlar's 1998 and 2000 Notes and the holders of the preferred and common stock
of Donlar and Donlar Biosyntrex.

     Subsequent discussions with the principal lenders resulted in the following
modifications to the reorganization plan:

     - Tennessee Farmers agreed to make the bridge loan, which is convertible
       into combined company common stock at the rate of $0.29 per share, the
       approximate market value of the Donlar Biosyntrex common stock at the
       time the bridge loan was made in March 2002. As part of that transaction,
       it was agreed that, upon the effectiveness of the merger, Tennessee Rural
       Health, would be issued 1,626,308 shares of common stock of the combined
       company and that the 3,849,377 shares of common stock of Donlar owned by
       TFIC, Inc., an affiliate of Tennessee Farmers, would be cancelled in the
       merger without the issuance to TFIC of any shares in the combined company
       as a result of such cancellation.

     - Dr. Martin agreed to the following in return for the issuance to him of
       5.0 million shares of the combined company common stock and a warrant to
       purchase 3.0 million shares of the combined company common stock for
       $0.68 per share: (i) the relinquishment of the right to receive royalty
       payments equal to one percent of all sales by Donlar or Donlar Biosyntrex
       during a ten year period beginning in 2000; (ii) the surrender for
       cancellation in the merger of 16,557,469 shares of Donlar common and
       preferred stock without the issuance of any shares in the combined
       company as the result of the merger; and (iii) the surrender for
       cancellation of options and warrants to purchase 38,407,063 shares of
       Donlar preferred and common stock at prices ranging from $0.01 to $5.50
       per share.

     - Willis Stein & Partners agreed that, upon the effectiveness of the
       merger, it would be issued 1.0 million shares of the combined company
       common stock and that the 20,278,457 shares of Donlar preferred stock
       owned by Willis Stein/Star Polymers would be cancelled in the merger
       without the issuance to them of any shares in the combined company as a
       result of such cancellation.

     - Certain creditors agreed to accept 465,000 shares of the combined company
       common stock in the satisfaction of contractual and accounts payable
       obligations.

     - 5 million shares of common stock would be reserved for issuance under the
       combined company's equity incentive plan.

     - All other options, warrants and rights to acquire Donlar or Donlar
       Biosyntrex stock would be cancelled.

     The 15 holders of the 1998 and 2000 Notes of Donlar, in the principal
amount of approximately $1.9 million, agreed to exchange their notes for an
equal amount of the combined company senior convertible preferred stock.


     As a result of the foregoing agreements, 12.7 million shares of the
combined company common stock, representing 61.1% on an outstanding basis and
13.7% on a fully diluted basis, will be issued in the merger to the holders of
preferred and common stock of Donlar (other than TFIC, Inc., Dr. Martin, Willis
Stein/Star Polymers, who are treated as specified above, and excluding the
approximately 1.6 million additional shares to be issued to Tennessee Rural
Health) and Donlar Biosyntrex (other than Donlar). That amount is being
allocated between the Donlar and the Donlar Biosyntrex shareholders on the basis
of the respective ownership


                                        26


of Donlar Biosyntrex common stock by Donlar on the one hand, and all other
shareholders of Donlar Biosyntrex, on the other hand.


     Accordingly, 68% of the 12.7 million shares of combined company common
stock, or 8.7 million shares, is being allocated to the Donlar shareholders
(other than TFIC, Inc., Dr. Martin, Willis Stein/Star Polymers with respect to
their Donlar shares, who are treated as specified above, and excluding the
approximately 1.6 million additional shares to be issued to Tennessee Rural
Health) and 32%, or 4.0 million shares, is being allocated to the Donlar
Biosyntrex shareholders (other than Donlar, whose shares are being cancelled).
As a result, and taking into account the cancellation of certain shares as
described above, in the merger each holder of Donlar preferred and common stock
(other than the holders of cancelled shares) will receive approximately 0.49
shares of the combined company common stock for each share of Donlar stock the
holder owns, each holder of Donlar Biosyntrex common and Series B preferred
stock (other than Donlar) will receive 0.26 shares of combined company common
stock for each share of Donlar Biosyntrex stock the holder owns and each holder
of Donlar Biosyntrex Series A preferred stock will receive one share of the
combined company common stock for each originally issued share of Series A
preferred stock the holder owns (excluding dividend shares). As is indicated in
the table above, following completion of the merger, the former shareholders of
Donlar (other than holders of cancelled shares and excluding the approximately
1.6 million additional shares to be issued to Tennessee Rural Health) will own
41.61% (9.36% on a fully diluted basis) of the combined company common stock,
and the former shareholders of Donlar Biosyntrex (other than Donlar) will own
19.48% (4.38% on a fully diluted basis) of such common stock.

     Under the Nevada Revised Statutes, notwithstanding the approval of the

Donlar Biosyntrex, a Donlar Biosyntrex shareholder can refuse the merger
consideration and exercise his or her appraisal rights and obtain payment for
the fair value of his or her capital stock by strictly following the
requirements of the applicable law. A copy of the relevant sections the Nevada
Revised Statutes is attached as Appendix C. You are urged to review the
applicable statute carefully as failure to comply may result in the loss of your
appraisal rights. DONLAR SHAREHOLDERS' APPRAISAL RIGHTS ARE NOT DISCUSSED IN
THIS INFORMATION STATEMENT/PROSPECTUS. WE RECOMMEND THAT DONLAR SHAREHOLDERS
CONSULT WITH THEIR LEGAL ADVISERS TO DETERMINE IF APPRAISAL RIGHTS ARE AVAILABLE
AND THE PROCEDURES THAT MUST BE COMPLIED WITH TO EXERCISE AND MAINTAIN THOSE
RIGHTS. FAILURE TO STRICTLY COMPLY WITH APPLICABLE LAW MAY RESULT IN A
FORFEITURE OF APPRAISAL RIGHTS.

     A beneficial shareholder of Donlar Biosyntrex stock may assert dissenters'
rights as to shares held on the shareholder's behalf only if the shareholder
submits to Donlar Biosyntrex the written consent of the shareholder of record to
the dissent not later than the time the beneficial shareholder asserts
dissenters' rights and the beneficial shareholder does so with respect to all
shares of which he is the beneficial shareholder or over which he has the power
to direct the vote.

     Shareholders who wish to assert dissenters' rights: (i) must deliver to
Donlar Biosyntrex, before the vote is taken, a written notice of the
shareholder's intent to demand payment for his or her shares if the merger is
effectuated and (ii) must not vote his or her shares in favor of merger.

     If the merger is authorized by the shareholders, Donlar Biosyntrex will
send a written dissenters' notice to all shareholders who provided timely notice
of their intent to demand payment for their shares and who did not vote their
shares in favor of the merger, within 10 days after effectuation of the merger.
The notice will:

          (a) state where the demand for payment must be sent and where and when
     certificates for Donlar Biosyntrex's shares are to be deposited;

          (b) supply a form for demanding payment;

          (c) set a date by which Donlar Biosyntrex must receive the demand for
     payment, which may not be less than 30 nor more than 60 days after the date
     the notice is delivered; and

          (d) be accompanied by a copy of Sections 92A.300 through 92A.500 of
     the Nevada Revised Statutes.

     A shareholder to whom a dissenter's notice is sent must, by the date set
forth in the dissenter's notice:

          (a) demand payment;

          (b) certify whether the shareholder acquired beneficial ownership of
     the shares before the date of the first announcement to the news media or
     to the shareholders of the proposed terms of the merger; and

          (c) deposit his or her certificates in accordance with the terms of
     the dissenter's notice.

                                        29


     Shareholders who do not demand payment or deposit their certificates where
required, each by the date set forth in the dissenter's notice, will not be
entitled to demand payment for dissenters' rights under Nevada law.

     Within 30 days after receipt a valid demand for payment, Donlar Biosyntrex
will pay each dissenter who complied with the procedures described by the Nevada
dissenters' rights statute the amount Donlar Biosyntrex estimates to be the fair
value of the shares, plus accrued interest. The payment will be accompanied by:

          (a) Donlar Biosyntrex's balance sheet as of the end of a fiscal year
     ending not more than 16 months before the date of payment, a statement of
     income for that fiscal year, a statement of changes in shareholders' equity
     for that fiscal year and the latest available interim financial statements,
     if any;

          (b) a statement of Donlar Biosyntrex's estimate of the fair value of
     the shares;

          (c) an explanation of how the interest was calculated;

          (d) a statement of the dissenters' rights to demand payment under
     Section 92A.480 of the Nevada Revised Statutes; and

          (e) a copy of Sections 92A.300 through 92A.500 of the Nevada Revised
     Statutes.

     Donlar Biosyntrex may elect to withhold payment from a dissenting
shareholder if such shareholder became the beneficial owner of the shares on or
after the date of the first announcement to the news media or to the
shareholders of the proposed terms of the merger. To the extent Donlar
Biosyntrex elects to withhold payment, after effectuating the merger, it will
estimate the fair value of the shares, plus accrued interest, and will offer to
pay this amount to each dissenter who agrees to accept it in full satisfaction
of the shareholder's demand. Donlar Biosyntrex will send with its offer:

          (a) a statement of Donlar Biosyntrex's estimate of the fair value of
     the shares;

          (b) an explanation of how the interest was calculated; and

          (c) a statement of the dissenters' rights to demand payment pursuant
     to Section 92A.480 of the Nevada Revised Statutes.

     A dissenter may notify Donlar Biosyntrex in writing of the dissenter's own
estimate of the fair value of the shares and interest due, and demand payment of
his or her estimate, less Donlar Biosyntrex's fair value payment or offer for
payment, or reject the offer for payment made by Donlar Biosyntrex and demand
payment of the dissenter's shares and interest due if the dissenter believes
that the amount paid or offered is less than the fair value of the dissenter's
shares or that the interest due is incorrectly calculated. A dissenter waives
his right to demand such payment unless the dissenter notifies Donlar Biosyntrex
of his demand in writing within 30 days after Donlar Biosyntrex made or offered
for payment for the dissenter's shares.

     If a demand for payment remains unsettled, Donlar Biosyntrex will commence
a proceeding within 60 days after receiving the demand for payment and petition
the court to determine the fair value of the shares and accrued interest. If
Donlar Biosyntrex does not commence the proceeding within the 60-day period, it
will be required to pay each dissenting stockholder whose demand remains
unsettled the amount demanded.

     Each dissenter who is made a party to the proceeding is entitled to a
judgment:

          (a) for the amount, if any, by which the court finds the fair value of
     the dissenter's shares, plus interest, exceeds the amount paid by Donlar
     Biosyntrex; or

          (b) for the fair value, plus accrued interest, of the dissenter's
     after-acquired shares for which Donlar Biosyntrex elected to withhold
     payment pursuant to Nevada law.

     The court will determine all of the costs of the proceeding, including the
reasonable compensation and expenses of any appraisers appointed by the court.
The court will assess the costs against Donlar Biosyntrex, except that the court
may assess costs against all or some of the dissenters, in the amounts the court
finds equitable, to the extent that the court finds the dissenters acted
arbitrarily, vexatiously or not in good faith in

                                        30


demanding payment. The court may also assess the fees and expenses of the
counsel and experts for the respective parties, in amounts the court finds
equitable:

          (a) against Donlar Biosyntrex and in favor of all dissenters if the
     court finds Donlar Biosyntrex did not substantially comply with the Nevada
     dissenters' rights statute; or

          (b) against either Donlar Biosyntrex or a dissenter in favor of any
     other party, if the court finds that the party against whom the fees and
     expenses are assessed acted arbitrarily, vexatiously or not in good faith
     with respect to the dissenters' rights provided under the Nevada
     dissenters' rights statute.

     If the court find that the services of counsel for any dissenter were of
substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against Donlar Biosyntrex, the court
may award to those counsel reasonable fees to be paid out of the amounts awarded
to the dissenters who were benefited.

     If a proceeding is commenced because Donlar Biosyntrex did not pay each
dissenter who complied with the procedures described by the Nevada dissenters'
rights statute the amount Donlar Biosyntrex estimated to be the fair value of
the shares, plus accrued interest within 30 days after receipt a valid demand
for payment, the court may assess costs against Donlar Biosyntrex, except that
the court may assess costs against all or some of the dissenters who are parties
to the proceeding, in amounts the court finds equitable, to the extent the court
finds that such parties did not act in good faith in instituting the proceeding.

     The foregoing summary of the rights of dissenting shareholders of Donlar
and Donlar Biosyntrex does not purport to be a complete statement of the
procedures to be followed by shareholders desiring to exercise any available
dissenters' rights. The preservation and exercise of dissenters' rights require
strict adherence to the applicable provisions of Nevada law, a copy of which is
attached hereto as Appendix C.

     After completion of the merger, we will notify you of the date on which the
merger was completed.

RECOMMENDATION OF THE DONLAR BIOSYNTREX BOARD AND DONLAR BIOSYNTREX'S REASONS
FOR THE MERGER

     The Donlar Biosyntrex board of directors has adopted the merger agreement
and has determined that the merger of Donlar Biosyntrex and Donlar is in the
best interests of Donlar Biosyntrex and its shareholders. The Donlar Biosyntrex
board, in accordance with Nevada law, unanimously recommends that you vote to
approve the merger agreement.

     Tennessee Farmers Life Insurance Company, as a condition of making a $2.127
million bridge loan facility available to the Donlar and Donlar Biosyntrex and
of amending and restating the terms of existing loans in the amount of
approximately $19.2 million, has required Donlar and Donlar Biosyntrex to merge.
Under the terms of the Bridge and Consolidated Term Loan Agreement with
Tennessee Farmers, the merger must be completed by July 7, 2002, or such later
date as agreed by Tennessee Farmers. Tennessee Farmers has extended the date for
completion of the merger until February 28, 2003. The Tennessee Farmers' loans
and the merger are part of an overall restructuring plan that will also involve
the elimination of approximately $25.26 million of the companies' liabilities.

     In reaching its decision to recommend the merger, the Donlar Biosyntrex
board of directors considered a variety of positive and negative factors. The
material positive factors considered by the board of directors were:

     - The bridge loan and the restructuring of the existing Tennessee Farmers'
       loans were necessary in order for Donlar Biosyntrex's continuance in
       operation, and Tennessee Farmers has required the merger as a condition
       of those transactions and can accelerate the loans if the merger does not
       occur by February 28, 2003.

     - Approximately $25.26 million of liabilities is being eliminated as part
       of the restructuring transactions.

     - The merger will simplify the two companies' capital structure thereby
       reducing accounting and legal costs and making the companies more
       attractive to potential investors and lenders.

                                        31


     - The overlap of management between the companies and the absence of a
       separate Donlar business should make for a seamless transition.

     The material negative factors considered by the board of directors were:

     - The restructuring would have a dilutive effect on the existing Donlar
       Biosyntrex shareholders.

     - There would be significant legal, accounting and printing costs in
       completing the restructuring.

     The alternatives to the restructuring plan (including the merger)
considered were obtaining additional private equity financing and merging the
companies' operations with a non-affiliate, but no private equity financing on
acceptable terms and in an adequate amount were located and no suitable
non-affiliated merger partners were found.

     The discussion in this section of the information and factors considered by
the Donlar Biosyntrex board is not intended to be exhaustive but includes all
material factors considered by the board. In reaching its determination to
approve and recommend the merger agreement and the merger, the Donlar Biosyntrex
board did not assign any relative or specific weights to the factors considered.
Individual directors may have given differing weights to different factors. The
Donlar Biosyntrex board unanimously approved the merger agreement and the other
transactions contemplated by the merger agreement as being in the best interests
of Donlar Biosyntrex and its shareholders.

     Accordingly, the board of directors of Donlar Biosyntrex, in accordance
with Nevada law, unanimously recommends that holders of its common and Series A
preferred stock vote "FOR" approval of the merger agreement.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendations of the Donlar Biosyntrex board with
respect to the merger, Donlar Biosyntrex shareholders should be aware that
officers and directors of Donlar and Donlar Biosyntrex have interests in the
merger.


     The executive officers and directors of Donlar and Donlar Biosyntrex, who
are identical, will serve as executive officers and directors of the combined
company following the merger. In addition, as of January 8, 2003, the directors
and executive officers of Donlar owned an aggregate of approximately 19,042,029
shares of Donlar common stock, 6,661,797 shares of Donlar preferred stock and
held options to purchase an aggregate of approximately 311,389 shares of Donlar
common stock at an exercise price ranging from approximately $0.30 to $5.50 and
87,000 shares of Donlar preferred stock at an exercise price ranging from
approximately $3.00 to $5.50. Under the terms of the merger agreement, Donlar's
directors (other than Dr. Robert Martin) and executive officers will receive the
same consideration for their shares of Donlar common and preferred stock as the
other Donlar shareholders and all options will be cancelled. As of January 8,
2003, the directors and executive officers of Donlar Biosyntrex owned 8,509,000
shares of Donlar Biosyntrex common stock (owned entirely by Dr. Martin and Mr.
Koskan) and held options to purchase an aggregate of approximately 1,150,000
shares of Donlar Biosyntrex common stock at a weighted average exercise price of
approximately $0.20. Under the terms of the merger agreement, Donlar's directors
and executive officers will receive the same consideration for their shares of
Donlar Biosyntrex stock as the other Donlar Biosyntrex shareholders and all
options to purchase Donlar Biosyntrex stock will be cancelled.


     Donlar has reached agreement with Dr. Robert Martin, who serves as a
director of both Donlar and Donlar Biosyntrex and will serve as a director of
the combined company, to (i) exchange approximately $9.9 million of original
principal amount of Donlar notes plus accrued interest for shares of the
combined company senior convertible preferred stock with a stated liquidation
value of $9.0 million and convertible into approximately 13.23 million shares of
the combined company's common stock, (ii) relinquish rights to receive royalty
payments from Donlar and Donlar Biosyntrex and surrender for cancellation all of
the Donlar common and preferred stock held by him, equaling approximately 10.56
million shares, in exchange for 5.0 million shares of the combined company's
common stock and (iii) surrender for cancellation options and warrants to
purchase over 38 million shares of Donlar stock for a warrant to purchase 3.0
million shares of the combined

                                        32



company's common stock for $0.68 per share. Dr. Martin will not receive any
other stock of the combined company as a result of the merger for his Donlar
shares, but will receive 1,187,940 shares of the combined company common stock
in exchange for the 4,569,000 shares of Donlar Biosyntrex common stock that he
owns. Dr. Martin agreed to vote his shares of voting stock of Donlar in favor of
the merger.


     Donlar owns approximately 33.28 million shares of common stock of Donlar
Biosyntrex which will be cancelled in the merger. The restructuring plan,
including the merger, involves the restructuring of the debt and capital
structure of both Donlar and Donlar Biosyntrex. See "Proposal 1 -- Approval of
Agreement and Plan of Merger -- Background of the Merger -- Restructuring Plan"
for further information.


     Immediately after completion of the restructuring plan, including the
merger, Dr. Martin will own, including the shares he will receive upon
conversion in the merger of the 4,569,000 shares of Donlar Biosyntrex common
stock that he owns, approximately 29.8% of the outstanding combined company
common stock and 24.3% on a fully diluted basis (i.e., assuming all convertible
or exchangeable securities including notes are converted or exchanged), Willis
Stein/Star Polymers will own approximately 4.8% of the outstanding combined
company common stock and 15.4% on a fully diluted basis, Tennessee Farmers will
own none of the outstanding combined company common stock and 37.2% on a fully
diluted basis and Tennessee Rural Health will own approximately 7.8% of the
outstanding combined company common stock and 1.8% on a fully diluted basis.

     Certain information regarding the ownership of Donlar Biosyntrex common
stock by certain beneficial owners and by management is incorporated herein by
reference to the Donlar Biosyntrex annual report on Form 10-KSB for 2001. Mr.
Koskan acquired 4.0 million shares of Donlar Biosyntrex common stock on December
19, 2002 and Dr. Martin acquired 4.0 million shares of Donlar Biosyntrex common
stock on December 23, 2002, increasing his holdings to 4,569,000 shares. Mr.
Koskan and Dr. Martin acquired the shares from a Donlar Biosyntrex shareholder
in private transactions.


DIRECTORS AND EXECUTIVE OFFICERS OF THE COMBINED COMPANY

     Donlar and Donlar Biosyntrex have a complete overlap of directors and
executive officers. These individuals will continue as the directors and
executive officers of the combined company in their same capacities. Information
concerning the identity and compensation of the directors and executive officers
and certain relationships and related transactions is contained in Donlar
Biosyntrex's annual report on form 10-KSB for 2001 which is incorporated in this
information statement/prospectus by reference.

     In addition to the transactions described in the Donlar Biosyntrex annual
report on Form 10-KSB for 2001, Donlar entered into change of control agreements
in 1998 with Larry Koskan, its President and Chief Executive Officer, and with
Robert Pietrangelo, its Chief Operating Officer. The change of control
agreements are for five year terms. They provide, among other things, that the
executive officer shall be paid severance benefits in an amount equal to 2.9
times his annual salary in the event he is terminated without cause (as defined
in the agreements) within twelve months before a change of control of Donlar (as
defined in the agreements) or within thirty-six months after a change of control
or the executive officer resigns for good reason (as defined in the agreements)
within two years a change of control. If an executive officer is entitled to
severance benefits, he shall also receive continuing health, disability and life
insurance coverage in accordance with plans maintained by Donlar for a period of
one year from the date his employment terminates. In addition, the agreements
provide for the acceleration of the vesting of any options to acquire Donlar
securities in the event of a change of control of Donlar or if the executive
officer resigns for good reason.

     The merger may constitute a change of control under the change of control
agreements. Larry Koskan has waived any rights he may have under his change of
control agreement as a result of the merger. In the event the merger constitutes
a change of control and Robert Pietrangelo is terminated without cause or
resigns for good reason within the applicable time periods provided for in his
change of control agreement, based on his current salary, the company estimates
that Robert Pietrangelo would be entitled to $464,000 in salary, $115,000 in
bonus, plus the other benefits described above valued at $89,278.

COMMON STOCK TO BE ISSUED AS PART OF THE RESTRUCTURING PLAN, INCLUDING THE
MERGER

     The common stock of the combined company to be issued in the restructuring
plan, including the merger, has no par value, no preemptive right, no special
dividend rights and one vote per share on all matters on which the shareholders
of the combined company are entitled to vote. In the event that the combined
                                        35


company declares or pays any dividends upon its common stock (whether payable in
cash, securities or other property) other than dividends payable solely in
shares of its common stock, the combined company shall also declare and pay to

ACCOUNTING TREATMENT

     Donlar intends to account for the merger on the "purchase" method of
accounting, in accordance with SFAS 141, "Business Combinations." The
transaction will be treated as a transfer under common control for Donlar's 68%
ownership in Donlar Biosyntrex and as a purchase of minority interest for the
remaining 32%.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

     The following discussion is a summary of the material U.S. federal income
tax consequences of the merger to the common shareholders of Donlar Biosyntrex
who receive Donlar common stock in exchange for their Donlar Biosyntrex common
stock pursuant to the merger. The discussion below is based upon the Internal
Revenue Code of 1986, as amended (the "Code"), Treasury Regulations thereunder
and administrative rulings and court decisions as of the date of this
information statement/prospectus.

                                        40


     No rulings have been, or will be, requested from the Internal Revenue
Service as to the federal income tax consequences of the merger. In addition,
there can be no assurance that the Internal Revenue Service will not take a
position contrary to one or more positions reflected below or that the positions
reflected below will be upheld by the courts if challenged by the Internal
Revenue Service. Future legislative, judicial or administrative changes or
interpretations could alter or modify the statements and conclusions set forth
below, and any such changes or interpretations could be retroactive and could
affect the tax consequences to the holders of Donlar Biosyntrex common stock.

     No tax opinion will be issued by Donlar Biosyntrex's tax advisors prior to
the consummation of the merger as to the material federal income tax
consequences of the merger. Donlar Biosyntrex has not yet filed its federal
income tax returns for the taxable years 2000 and 2001 and does not have
available the necessary information for its tax advisors to render an opinion on
the federal income tax consequences of the proposed merger. Once these tax
returns are filed and additional information is gathered, the combined company
will seek an opinion on the federal income tax consequences of the merger from
its tax advisors. If such an opinion is obtained, copies will be made available
to shareholders.

     The material U.S. federal income tax consequences of the merger are
uncertain. There are two ways the merger transaction could be treated. First,
the merger could be treated as a "reorganization" under Section 368(a)(1)(A) of
the Code, in which case the federal income tax consequences to the Donlar
Biosyntrex common shareholders would be as follows:

          (1) no gain or loss will be recognized by a holder of Donlar
     Biosyntrex common stock upon the exchange of Donlar Biosyntrex common stock
     solely for Donlar common stock;

          (2) the basis of the Donlar common stock received by a holder of
     Donlar Biosyntrex common stock pursuant to the merger will be the same as
     the basis of the Donlar Biosyntrex common stock exchanged therefor; and

          (3) the holding period of the Donlar common stock received by a holder
     of Donlar Biosyntrex common stock pursuant to the merger will include the
     holding period of the Donlar Biosyntrex common stock exchanged therefor,
     provided the Donlar Biosyntrex common stock is held as a capital asset by
     the shareholder at the effective time of the merger.

     If the merger does not qualify as a reorganization, the exchange of Donlar
Biosyntrex common stock by a holder for Donlar common stock will be a taxable
exchange. In such a case, a holder will recognize gain (or loss) to the extent
that the fair market value of Donlar common stock received in exchange for
Donlar Biosyntrex stock held by that holder is greater than (or less than) the
holder's tax basis in the Donlar Biosyntrex stock. Any gain or loss recognized
will be capital gain or loss, provided the Donlar Biosyntrex common stock is
held as a capital asset by the shareholder at the effective time of the merger,
and will be long-term gain or loss if the stock has been held more than one year
at the effective time of the merger. For individuals, the maximum federal income
tax rate applicable to long-term capital gains is generally 20%. Deductions for
capital losses, whether short- or long-term, are subject to various limitations.

     The discussion above does not purport to deal with all tax aspects of
federal income taxation that may affect particular holders of Donlar Biosyntrex
common stock in light of their individual circumstances, and is not intended for
holders subject to special treatment under the tax law (including dealers in
securities, financial institutions, insurance companies, tax-exempt
organizations, non-United States persons, holders who hold their stock as part
of a hedge, appreciated financial position, straddle or conversion transaction,
holders who do not hold their stock as capital assets and holders who acquired
their stock pursuant to the exercise of options or otherwise as compensation).
In addition, the discussion does not consider the effect of any applicable
state, local or foreign tax laws.

     EACH HOLDER OF DONLAR BIOSYNTREX COMMON STOCK IS URGED TO CONSULT ITS TAX
ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO THE SHAREHOLDER OF THE MERGER,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS,
AND OF CHANGES IN APPLICABLE TAX LAWS.

            NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                             FINANCIAL INFORMATION

PRO FORMA ADJUSTMENTS

     The following pro forma adjustments have been made to the unaudited
condensed consolidated pro forma financial statements for the year ended
December 31, 2001 and as of and for the nine-months ended September 30, 2002.

          1.  To record the issuance of 1,626,308 shares of common stock of the
     combined company to Tennessee Rural Health, a 6% shareholder of Donlar and
     holder of approximately $21.3 million of the debt of Donlar and Donlar
     Biosyntrex. Because these shares are to be issued as part of the
     restructuring plan, the expense (fair value of $0.33 per share at date of
     measurement, March 18, 2002) associated with these shares is treated as
     additional debt conversion inducement expenses. The entire expense was
     recognized at March 18, 2002. The pro forma adjustment is non-recurring and
     only included on the pro forma balance sheet.

          2.  To record the exchange with Willis Stein/Star Polymers of
     $9,000,000 in notes plus accrued interest of approximately $2,473,000 for
     shares of a new series of senior convertible preferred stock of the
     combined company with a stated liquidation value of $9,000,000, convertible
     into 13,235,294 shares of common stock of the combined company. No
     dividends may be paid on the senior convertible preferred stock until all
     Tennessee Farmers Life Insurance Company debt has been repaid. This
     transaction has been treated as a conversion of debt with no beneficial
     conversion features and the accrued interest has been treated as additional
     paid in capital. The number of common shares that the $9 million of
     preferred stock can be converted into is determined by the loan agreement
     and the terms of the preferred stock. There is no beneficial conversion
     feature as the conversion rate is not in the money. The interest that would
     have been accrued during the periods presented is shown as a pro forma
     adjustment to the statement of operations, since the debt is being
     exchanged for equity.

          3.  To record the exchange with Dr. Martin of $9,900,000 in notes plus
     accrued interest of approximately $2,139,000 and less related debt discount
     of $530,000 for shares of senior convertible preferred stock with a stated
     liquidation value of $9,000,000 and convertible into 13,235,294 shares of
     common stock of the combined company. No dividends may be paid on the
     senior convertible preferred stock until all Tennessee Farmers debt has
     been repaid. This transaction has been treated as a conversion of debt with
     no beneficial conversion features and the accrued interest has been treated
     as additional paid in capital. The number of common shares that the $9
     million of preferred stock can be converted into is determined by the
     Tennessee Farmers' loan agreement and the terms of the preferred stock.
     There is no beneficial conversion feature as the conversion rate is not in
     the money. The interest and amortization that would have been accrued
     during the periods presented are shown as pro forma adjustment to the
     statements of operations, since the debt is being exchanged for equity.

          4.  To record the issuance of 5,000,000 shares of common stock of the
     combined company to Dr. Martin in relinquishment of rights to receive
     royalty payments from Donlar and for the cancellation of approximately
     16.56 million shares of Donlar common and preferred stock. This transaction
     has been treated as additional conversion expense in an amount equal to the
     fair value of the shares issued ($0.33 per share). This is a non-recurring
     event and as such is only included on the pro forma balance sheet.

          5.  To record the issuance to Dr. Martin of a warrant to purchase
     3,000,000 shares of the combined company common stock for $0.68 per share,
     in exchange for the cancellation of all previously held options and
     warrants to purchase shares of Donlar stock held by Dr. Martin. The fair
     value of the previously held options and warrants is equal to $29,555. The
     fair value of the new warrant is $330,000. This transaction has been
     treated as additional conversion expense equal to the difference of the
     fair values of the old warrants and options and the new warrant. This is a
     non-recurring event and as such is only included on the pro forma balance
     sheet.

            NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                      FINANCIAL INFORMATION -- (CONTINUED)

          6.  To record the exchange of the 1998 and 2000 Notes of approximately
     $1,900,000 plus accrued interest of $850,000 and less related debt discount
     of $138,000 for shares of senior convertible preferred stock with a stated
     liquidation value equal to the amount of the Notes and convertible into
     2,800,000 shares of common stock of the combined company. Because the
     common stock of the combined company has no par value, the entire balance
     has been treated as additional paid in capital. The interest and
     amortization that would have been accrued during the periods presented are
     shown as pro forma adjustments to the statement of operations, since the
     debt is being exchanged for equity.

          7.  To record the conversion in the merger of Donlar Biosyntrex stock
     (except shares held by Donlar) into shares of the combined company at an
     exchange rate of 0.26 shares of common stock of the combined company for
     each share owned by the minority shareholders of Donlar Biosyntrex. These
     minority owned shares of Donlar Biosyntrex consist of 15,537,142 shares of
     common stock, 39,124 shares of Series A preferred stock and 449 shares of
     Series B preferred stock. These shares will be converted in the merger into
     4,049,765 shares of common shares of the combined company. This transaction
     constitutes a step acquisition of the minority interests resulting in an
     acquisition price of approximately $1,336,500. This amount has been
     reflected as goodwill in a preliminary purchase price allocation. The
     purchase price adjustment to goodwill was calculated by taking the number
     of shares converted into by the $0.33 share value at the agreement date.

          8.  To record the issuance of 465,000 shares to pay certain claims. In
     connection with the restructuring plan, Donlar and Donlar Biosyntrex have
     reached agreements to issue 465,000 shares of common stock of the combined
     company to accounts payable and other creditors as payment for open
     payables and claims against either Donlar or Donlar Biosyntrex. The
     issuances will result in an adjustment to debt conversion expense of
     $92,400. The issuances of the shares are contingent upon the completion of
     the merger. The creditors consist of four individuals. Two of these
     creditors had outstanding accounts payable of $61,050. The other two
     creditors had an outstanding sales contract and consulting contract which
     were bought out by these issuances. This is a non-recurring event and as
     such is only recorded in the pro forma balance sheet.

     The following matters took place prior to September 30, 2002 and have been
reflected in the Donlar Corporation financial statements for the nine months
then ended.

          a. Includes the beneficial conversion feature associated with the
     $2,127,000 bridge loan. The bridge loan is convertible into common stock of
     the combined company at the rate of $0.29 per share, an aggregate of
     7,334,483 shares of common stock. This may be done at any time, at the
     option of the lender. The pro forma adjustment is non-recurring and only
     included on the pro forma balance sheet. As of the date of the loan
     agreement, March 18, 2002, the price of Donlar Biosyntrex common stock was
     $0.33 per share. Therefore, a beneficial conversion feature is associated
     with the conversion of these shares, which is the $0.04 difference between
     the share price and the conversion price, resulting in an adjustment of
     $289,655. Since the term of the loan is one year, this expense was
     recognized as of the date of the loan agreement, March 18, 2002.

          b. Reflects the changed terms of outstanding loans to Donlar as of
     March 18, 2002 whereby the principal balance of $17.64 million was restated
     and made the joint and several obligation of Donlar and Donlar Biosyntrex
     in the total amount of $19.2 million, reflecting the original amount of the
     loans and accrued interest. The restated loans are convertible at a rate of
     $0.68 into common stock of the combined company. The original loans were
     also convertible into common stock of Donlar at a rate of $1.01. Because
     there were significant changes in the terms of the restated loans, there is
     no induced conversion associated with these restated loans and they have
     been treated as new debt. This reclassification was recognized as of March
     18, 2002.

                                        48

            NOTES TO THE UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                      FINANCIAL INFORMATION -- (CONTINUED)

     The following transactions did not result in adjustments to the pro forma
financial statements:

     - The conversion in the merger of Donlar stock (except shares owned by
       TFIC, Inc., Willis Stein/Star Polymers and Dr. Martin) into the common
       stock of the combined company at an exchange rate of 0.49 shares of
       common stock of the combined company for each share of Donlar stock.
       These pre-merger shares of Donlar consist of 14,908,335 preferred shares
       and 2,848,735 common shares. These shares will be converted in the merger
       into 8,652,288 shares of common stock of the combined company.

     - The cancellation of all outstanding employee options to acquire shares of
       Donlar or Donlar Biosyntrex. Because none of these securities were in the
       money, there is no compensation expense associated with them.

     - The exchange of all of the equity securities held by Willis Stein/Star
       Polymers for 1,000,000 shares of the combined company common stock.
       Willis Stein/Star Polymers owns 20,278,457 shares of Donlar preferred
       stock, with a stated liquidation value of $15,614,311. These shares will
       be exchanged for 1,000,000 shares of common stock of the combined company
       with no par value. This transaction will be recorded as additional paid
       in capital.

     - The conversion features of the bridge loan and the restated loans. The
       bridge loan is convertible at the rate of one share of the combined
       company common stock per $0.29 of outstanding principal. The restated
       loans are convertible at a rate of $0.68 of outstanding principal. These
       loans are convertible at the option of the loan holder.

     The following is a summary of the shares, warrants and options of the
combined company on a fully diluted basis after the effect of all components of
the merger transaction referenced in the previously discussed pro forma matters.
Also, see tables under "Proposal 1 -- Approval of Agreement and Plan of
Merger -- Determination of the Terms of the Merger and Restructuring Plan."

                           BUSINESS OF THE COMPANIES

DONLAR CORPORATION

BUSINESS

     Donlar Corporation was organized in 1990 to develop, manufacture and market
an entirely new protein technology with the potential to replace a generation of
older, non biodegradable and potentially toxic chemicals. This new family of
biopolymers, known as thermal polyaspartates or TPA, is non hazardous, non
toxic, hypoallergenic, environmentally friendly and biodegradable. These
proteins are used in a broad range of industrial, agricultural and consumer
markets. Donlar has 140 global patents that protect its technology, products and
marketplace. The U.S. Government recognized the environmental benefits of this
technology in 1996 when it awarded Donlar the first Presidential Green Challenge
Chemistry Award.

     TPA products are beta proteins (biopolymers) manufactured from the common
biological amino acid, L-aspartic acid. TPA is a highly active biopolymer that
is completely soluble in water. By varying the manufacturing method, different
properties can be built into the biopolymer, tailoring it to a specific use.
Products are formulated and packaged into both powder and liquid forms.

     In transactions closing in November 2000 and January 2001, Donlar
Biosyntrex, then known as Biomune Systems, Inc., acquired from Donlar in
exchange for 41,279,520 shares of Donlar Biosyntrex's common stock, representing
approximately 96% of Donlar Biosyntrex's shares then outstanding on a fully
diluted basis, substantially all of Donlar's businesses and assets plus cash
consideration. Donlar also transferred to Donlar Biosyntrex all technology, know
how and patents for the crop management and oil field businesses created after
November 3, 2000, as well as all technology resulting from Donlar pharmaceutical
research and development activities after November 3, 2000. Although Donlar
Biosyntrex was the surviving corporation in this transaction, Donlar owned 96%
of the Donlar Biosynrex common stock after the transaction and was, therefore,
treated as the acquiring company for accounting purposes. Purchase accounting
was used for this transaction because it represented a change of control of
Donlar Biosyntrex and a portion of the purchase price was paid in cash. Since
the closing of the foregoing transactions, Donlar has had no substantial
business operations and has been a holding company for Donlar Biosyntrex.

     Since the closing of the foregoing transactions, Donlar's percentage
ownership of Donlar Biosyntrex's common stock has decreased to approximately 68%
as a result of issuances of common stock by Donlar Biosyntrex and the
cancellation of 8.0 million of the shares held by Donlar.

REGULATORY MATTERS

     The marketing of certain of Donlar Biosyntrex's products is subject to
regulatory oversight in certain jurisdictions. In each of the fifty states, the
respective departments of agriculture have various requirements for the
registration of different types of agricultural products to be used within that
state. Donlar Biosyntrex's products do not require registration in 26 states. In
the remaining 24 states, the purpose for registration is to assure
consumers/growers that the products can be used safely and that they have
demonstrated a variety of benefits such as protection against insects or root
growth enhancement. The state departments of agriculture that require
registration publish guide lines for the submission of several different kinds
of data in order to make a determination for registration. These data include
laboratory, green house, university and field test results, as well as toxicity,
environmental and general safety information. Each state has its own
requirements which range from minimal information coupled with a small fee to
extensive data sets that cover several years of experience and may be very
expensive to comply with. The review process may include several resubmissions
of updated data or other kinds of information and may take years. States may
also give limited registration to products that cover only one or more kinds of
plants.

     Donlar Biosyntrex's products have been registered in 20 of the 24 states
requiring registration, and the company is pursuing registration in the four
other states, South Dakota, Alabama, Mississippi and Pennsylvania. When the
department of agriculture of a specific state registers the products, those
products may then be sold with required information that is printed on the
product's label such as the plants/crops that the

                                        51


product can be used on, instructions on how to safely apply the product, maximum
quantities to use and a variety of safety and toxicity handling precautions.

     Donlar Biosyntrex's products are also subject to approval by foreign
regulatory authorities, but there are no federal regulatory approvals required
for distribution. A loss of a product registration in a key U.S. state would
significantly limit the combined company's ability to market its crop nutrition
products.

DESCRIPTION OF PROPERTIES

     Donlar constructed a TPA manufacturing facility in Peru, Illinois on a 40
acre parcel purchased by Donlar in 1996. This 50,000 square foot facility
currently contains two chemical reactors, the larger of which is designed to
produce nominally, 30 million pounds of TPA products annually. The facility is
large enough to accommodate additional reactors and may be expanded modularly
without substantial engineering or technical expenses or delays. The Peru
facility is strategically located near barge, rail and road transportation
facilities. Donlar Biosyntrex, Donlar's majority owned subsidiary, conducts its
manufacturing operations in the Peru, Illinois plant. The Peru facility is
subject to a mortgage under a Bridge and Consolidated Term Loan Agreement with
Tennessee Farmers Life Insurance Company.

     Donlar shares administrative office space with Donlar Biosyntrex in an
approximately 6,700 square foot office and laboratory space in Bedford Park,
Illinois which is leased from the Illinois Institute of Technology. The lease is
currently on a month-to-month basis. The monthly lease obligation is $9,000.

LEGAL PROCEEDINGS

     None.

MARKET FOR COMMON STOCK AND RELATED MATTERS

     Market Information.  There is no public trading market for Donlar's common
or preferred stock. Upon consummation of the Restructuring Plan, including the
Merger, it is expected that the combined company will have outstanding
approximately 20.8 million shares of common stock, approximately $21.0 million
of debt convertible into approximately 34.4 million shares of common stock,
approximately $19.9 million stated liquidation value of senior convertible
preferred stock convertible into approximately 29.3 million shares of common
stock, a warrant to purchase 3.0 million shares of common stock and an employee
stock option plan for which 5.0 million shares of common stock shall be
reserved.


     Holders of Common Stock.  As of January 8, 2003, there were approximately
337 holders of record of Donlar's common and preferred stock. Immediately
following the completion of the restructuring plan, including the merger, it is
expected that there will be approximately 420 holders of record of Donlar common
stock (assuming no Donlar and Donlar Biosyntrex shareholders exercise their
dissenters' rights).


     Dividends.  Donlar has not declared any cash dividends on its common stock
in the last two fiscal years or at any time thereafter. Pursuant to the terms of
the loan agreement, Donlar is prohibited from paying any dividends without the
approval of its lender. In the event that the combined company declares or pays
any dividends upon its common stock (whether payable in cash, securities or
other property) other than dividends payable solely in shares of its common
stock, the combined company shall also declare and pay to the holders of its
senior convertible preferred stock the dividends which would have been declared
and paid with respect to its common stock issuable upon conversion of its senior
convertible preferred stock had all of the outstanding senior convertible
preferred stock been converted immediately prior to declaration of such dividend
upon its common stock.

MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

     The following discussion and analysis of Donlar's financial condition and
results of operations should be read in conjunction with the consolidated
financial statements and the notes thereto appearing elsewhere in this
information statement/prospectus.

                                        52


 OVERVIEW

     From 1997 until November of 2000, Donlar's subsidiary, Donlar Biosyntrex,
was primarily engaged in the distribution and sale of nutritional and
nutraceutical products. Donlar Biosyntrex's principal products were biologic
nutraceutical supplements and sports and nutrition bars. As a result of the
transactions that were completed in 2000 and in early 2001, all of the
operational activities of Donlar are now conducted by its subsidiary, Donlar
Biosyntrex. The former Donlar businesses are now Donlar Biosyntrex's principal
businesses and Donlar Biosyntrex is phasing out its nutritional and
nutraceutical business. Donlar Biosyntrex's marketing, sales, distribution and
administrative operations are conducted from Donlar's headquarters in Bedford
Park, Illinois, and its manufacturing operations are conducted from Donlar's
Peru, Illinois facility.

     Donlar Biosyntrex's reorganized businesses are conducted through three
product lines:

     - BioPolymers, consisting of the performance chemicals business acquired
       from Donlar;

     - AgriSciences, consisting of the agricultural business acquired from
       Donlar; and

     - Optim Nutrition, consisting of Donlar Biosyntrex's nutritional and
       nutraceuticals business (being phased out).

     Donlar Biosyntrex current business is the production and marketing of
products initially developed by Donlar. Historically, Donlar began as a research
and development company to exploit the possibilities of developing,
manufacturing and marketing a new family of biodegradable polymers known as
thermal polyaspartates (TPA). Although there was no market at the time of
Donlar's inception for a new so-called "green chemistry," Donlar concluded that
a market would develop if the technology and products were available. It also
determined that the development of this technology and market would also require
substantial capital.

     It took about ten years and the use of extensive capital to reach the point
of commercialization whereby Donlar Biosyntrex's products and markets are
protected by a global intellectual property portfolio of patents. The products
are manufactured in a modern plant capable of producing high quality products at
low cost and are sold in a marketplace where Donlar Biosyntrex's TPA products
can compete on a cost/performance basis with conventional chemicals.

     As a result of this historical development, Donlar Biosyntrex' revenues
from the sale of its products increased from $1.4 million in 2000 to $2.4
million in 2001. Commercialization of the products began approximately two years
ago focusing on the building of three market's in oil production, agriculture
and detergents.

  YEAR-END RESULTS OF OPERATIONS

  2001 Compared to 2000

     During the year ended December 31, 2001, Donlar had revenues of $2,352,834,
compared to $1,381,994 for the year ended December 31, 2000. The increase in
revenues was due to growth in the BioPolymers product line from both new and
existing customers and new products. Approximately $17,000 is related to new
customers, approximately $104,000 is related to new products and approximately
$818,000 is related to additional business from the established customer base.
These increases are offset by a slight decrease in sales of agricultural
products.

     Cost of revenue was $2,639,022 in 2001, compared to cost of revenue of
$2,097,189 in 2000. This increase was due to the increased sales in 2001, offset
by decreased staff in the manufacturing area, as well as other cost reductions
at the manufacturing facility in Peru, Illinois for plant supplies, plant
repairs and equipment rental.

     Research and development cost decreased from $1,121,749 in 2000 to $821,414
in 2001 due to a reduction in research projects undertaken and a related
reduction in staffing levels for research.

     Selling, general and administrative expenses increased from $3,689,944 in
2000 to $5,864,860 in 2001. This increase in 2001 was the result of a $1.45
million increase in the amortization of goodwill and

                                        53


$3.17 million in non-cash expenditures incurred in 2001. The non-cash
expenditures were in the nature of the issuances of common stock and warrants
exercisable for common stock to service providers in return for consulting
services. The increases were offset by a $440,000 reduction in employee expenses
due to staff reductions, a $75,000 reduction in travel expenses, a $98,000
reduction in consulting fees paid in cash, a $110,000 reduction in professional
fees and $124,000 reduction in advertising expenses. The non-cash expenditures
for consulting services represent payments for these services in the Donlar
Biosyntrex common stock.

     Other expense increased from $7,136,982 in 2000 to $13,302,928 in 2001 as a
result of the loss on the repayment of shareholder receivable discussed in Note
J of the Notes to Donlar Corporation's and subsidiaries consolidated financial
statements for the years ended December 31, 2001 and 2000 and an $864,434 write
down of investments in 2001 partially offset by a reduction in interest expense
from $7.24 million in 2002 to $7.08 million in 2001. In addition, in 2000 Donlar
Biosyntrex realized a gain of $100,000 on the sale of a product line.

     As a result of the foregoing, the net loss increased from $12,663,870 in
2000 to $21,465,313 in 2001.

  2000 Compared to 1999

     During the year ended December 31, 2000, Donlar had revenues of $1,381,994,
compared to $793,723 for the year ended December 31, 1999. The increase in
revenues was due to growth in the BioPolymers segment from new customers and new
products.

     Cost of revenues was $2,097,189 in 2000, compared to cost of revenues of
$3,634,861 in 1999. This decrease was due to a large inventory write down in
1999 to reduce the inventory to lower of cost or market value.

     Operating expenses were $6,908,882 for 2000, compared to $4,896,524 in
1999. This slight decrease was due cost reduction initiatives implemented by
Donlar, partially offset by costs associated with the acquisition of Donlar
Biosyntrex.

     Interest expense increased from $4,443,756 in 1999 to $7,236,982 in 2000.
This increase was due to increases in borrowings and in the amortization of debt
discount.

     As a result of the foregoing, the net loss increased from $12,149,702 in
1999 to $12,663,870 in 2000.

 YEAR-END LIQUIDITY AND CAPITAL RESOURCES

     Historically, Donlar has been unable to finance its operations from cash
flows from operating activities. As a result of the recent agreement with
certain creditors to restructure principal and interest payments, Donlar was
able to pay current operating expenses in the fourth quarter of 2001 and the
first quarter of 2002. As of December 31, 2001, Donlar had cash of $3,746. In
March of 2002, Donlar obtained additional bridge financing in connection with
the restructuring of its debt, but has no other plans for its continued
financing. Donlar believes based on its current budget and sales that it will be
able to pay its expenses for the next year other than payments under its bridge
financing from Tennessee Farmers due in March 2003 and it plans to enter into
additional negotiations with Tennessee Farmers regarding such payments. The
payments due Tennessee Farmers in March 2003 consist of $1,120,255 in interest
and $222,500 in principal due on the restated loans and $188,771 in interest and
$1,827,000 in principal due on the bridge financing. The total of the payments
due in March 2003 is $3,358,526.

     Donlar Biosynstrex reduced its cash flows used in operations from
$6,616,679 in 2000 to $1,672,494 in 2001, due to the continued effort to reduce
costs and the increased revenue during 2001. Donlar Biosyntrex has been able to
decrease its inventory levels by approximately $850,000 from 2000. In addition,
it has increased its accrued liabilities by approximately $3.2 million,
primarily as a result of accrued interest.

     Cash flows used in investing activities decreased to $156,536 in 2001 from
$423,670 during 2000. This is due to Donlar Biosyntrex limiting its capital
expenditures during 2001 and the fact that the costs associated with the reverse
merger transaction with Donlar Biosyntrex were incurred in 2000.
                                        54


     Cash flows provided by financing activities decreased from $7,537,506
during 2000 to $956,341 during 2001. The cash from financing activities in 2000
resulted from the sale of convertible debt and the exercise of warrants.

     The audited consolidated financial statements of Donlar for 2001 have been
prepared on the assumption that it will continue as a going concern. Donlar's
independent public accountants have issued their report dated April 5, 2002,
that includes an explanatory paragraph stating that Donlar's recurring losses,
among other things, raise substantial doubt about Donlar's ability to continue
as a going concern.

 THIRD-QUARTER RESULTS OF OPERATIONS

     Comparison of the nine months ended September 30, 2002 with the nine months
ended September 30, 2001.

     During the nine months ended September 30, 2002, Donlar had revenues of
$2,808,005, compared to $1,687,902 for the comparable nine-month period in 2001.
The increase in sales was due to growth in sales of the Donlar Biosyntrex's
products, principally in the oil field market.

     Cost of revenues was $2,268,876 for the nine months ended September 30,
2002, compared to $2,043,022 for the same period in 2001. This increase in cost
of revenues is related to increased sales offset by decreased staff in the
manufacturing area, as well as other cost reductions at Donlar's manufacturing
facility in Peru, Illinois.

     Operating expenses were $4,348,066 for the nine-month period ended
September 30, 2002, compared to $7,255,803 for the nine month period ended
September 30, 2001. This decrease is due to decreased staff, as well as other
cost reductions related to consulting, outside research products, professional
fees and travel expenses.

     Interest expense decreased from $5,255,854 for the first nine months of
2001 to $4,170,904 for the first nine months of 2002. This decrease was due to a
decrease in the amortization of debt discount.

     During the nine months ended September 30, 2002, Donlar had a net loss of
$6,829,912 compared to a net loss of $16,174,420 for the nine months ended
September 30, 2001. This decrease in the net loss was attributable primarily to
the decrease in interest expense and increased sales offset by the acceleration
of debt discount amortization related to the debt restructuring, which is shown
as extraordinary loss, and the loss on the repayment of shareholder receivable
discussed in Note J of the Notes to Donlar Corporation's and subsidiaries
consolidated financial statements for the years ended December 31, 2001 and
2000.

 THIRD-QUARTER LIQUIDITY AND CAPITAL RESOURCES

     Historically, Donlar has been unable to finance its operations from cash
flows from operating activities. As of September 30, 2002, it had cash of
$15,737. As a result of the recent agreement with its creditors, principally
Tennessee Farmers Life Insurance Company, Willis Stein, Dr. Martin and the 1998
and 2000 noteholders, to restructure principal and interest payments, Donlar was
able to pay current operating expenses in the fourth quarter of 2001 and the
first and second quarter of 2002. In March of 2002, Donlar obtained additional
bridge financing in connection with the restructuring of its debt, but has no
other plans for its continued financing. Donlar, under its bridge financing, has
a quarterly interest payment of approximately $21,000 due on the last business
day of each quarter. Donlar intends to carefully control its use of cash for the
balance of 2002. As a long-term matter, Donlar will require additional financing
to maintain operations. Donlar believes based on its current budget and sales
that it will be able to pay its expenses for the next year other than payments
under its bridge financing and other loans from Tennessee Farmers due in March
2003, approximately $3.36 million, and it plans to enter into additional
negotiations with Tennessee Farmers regarding such payments.

     In the first nine months of 2002, Donlar had a net increase in cash and
cash equivalents of $11,991, compared to a net decrease in cash and cash
equivalents in the same period of 2001 of $872,377. The increase

                                        55


in cash was the result of increased sales and reduced operating costs and the
financing activities discussed below.

     Donlar decreased its cash flows used in operations from $1,499,546 in the
first nine months of 2001 to $1,219,458 in the same period in 2002, due to
decreased staff, as well as other cost reductions related to consulting, outside
research products, professional fees and travel expenses.

     Cash flows used in investing activities decreased to $32,104 in the first
nine months of 2002 from $121,926 in the same period in 2001. This is due to
Donlar limiting its capital expenditures.

     Cash flows provided by financing activities increased from $749,095 during
the first nine months of 2001 to $1,263,553 in the same period in 2002. The cash
flows from financing activities during the first nine months of 2002 resulted
from borrowings of approximately $1.8 million from Tennessee Farmers and the
repayment of a short-term note held by Tennessee Farmers in the amount of
$252,000 and the payment of $270,419 in legal and other costs associated with
the borrowings from Tennessee Farmers.

DONLAR BIOSYNTREX CORPORATION


     This information statement/prospectus is accompanied by a copy of Donlar
Biosyntrex's annual report on Form 10-KSB for the fiscal year ended 2001 and
quarterly report on Form 10-QSB for the fiscal quarter ended September 30, 2002.


                       PROPOSAL 2 -- APPROVAL OF ADOPTION
                    OF THE DONLAR 2002 EQUITY INCENTIVE PLAN

     The board of directors of Donlar and Donlar Biosyntrex have adopted the
Donlar 2002 Equity Incentive Plan, attached hereto as Appendix B, to be
effective as an equity incentive plan of the combined company upon approval by
the shareholders and consummation of the merger. Under the equity incentive
plan, the combined company may grant options to eligible participants for the
purchase of up to an aggregate of 5.0 million shares of the combined company's
common stock. Other than the number of shares issuable under the plan which was
increased from 2.0 million to 5.0 million, the equity incentive plan is
essentially identical to the Donlar Biosyntrex 2001 Equity Incentive Plan which
was adopted by the Donlar Biosyntrex board of directors and approved by the
Donlar Biosyntrex shareholders in 2001.

     Key provisions of the equity incentive plan include the following:

     - The definition of persons eligible to participate in the Equity Incentive
       Plan includes employees and directors of the combined company, as well as
       consultants and other persons who contribute to the business of the
       combined company as selected at the discretion of the committee
       administering the plan.

     - The committee will be comprised of the combined company's compensation
       committee. The committee has broad authority to select persons to receive
       awards under the plan and to establish the terms and conditions
       applicable to the exercise of such awards and the duration of the awards.

     - Total number of shares issuable upon exercise of grants under the equity
       incentive plan is 5.0 million shares of common stock.

     - Awards under the plan will be made in the form of incentive and
       nonqualified stock options to purchase common stock of the combined
       company at prices and on terms consistent with the terms of the plan, as
       established by the committee.

     - The purchase price of the common stock subject to an incentive stock
       option may be not less than 100% of the fair market value of such stock
       on the date the option is granted, as determined by the

                                        56


       committee. The purchase price of the common stock subject to a
       nonqualified stock option may be not less than 85% of the fair market
       value of the common stock on the date the option is granted, as
       determined by the committee.

     - The period within which the option shall vest and may be exercised shall
       determined by the committee; however no option shall be exercisable after
       ten years from the date of grant.

     - No incentive stock options may be granted to any employee if at the time
       the option is granted such employee owns stock possessing more than 10%
       of the total combined voting power of all classes of stock of the
       combined company or its parent or its subsidiaries unless at the time
       such option is granted the option price is at least 110% of the fair
       market value of the stock subject to the option and, by its terms, the
       option is not exercisable after the expiration of five years from the
       date of grant.

     The Donlar Biosyntrex board of directors believes that the equity incentive
plan will provide the combined company with flexibility in compensating persons
who contribute in the future to the successful operation and growth of the
combined company.

     The Donlar Biosyntrex board of directors recommends a vote FOR the approval
of the adoption of the equity incentive plan.

                                 OTHER MATTERS

     Donlar Biosyntrex does not intend to hold a 2002 annual meeting prior to
the scheduled completion of the merger. If the merger is not completed and
Donlar Biosyntrex does hold a 2002 annual meeting, Donlar Biosyntrex will notify
you of such meeting, including the date on which shareholder proposals must be
received at Donlar Biosyntrex's executive offices in order to be considered for
inclusion in the proxy materials relating to such meeting.

     The validity of the issuance of the shares of common stock registered
hereby will be passed upon for Donlar by Duane Morris LLP, Philadelphia,

                      DONLAR CORPORATION AND SUBSIDIARIES

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accompanying unaudited condensed consolidated financial statements of
Donlar Corporation ("Donlar") and subsidiaries (the "Company") for the nine
months ended September 30, 2002, do not include all information and footnotes
necessary for a fair presentation of financial position, results of operations
and cash flows in conformity with accounting principles generally accepted in
the United States of America. For further information refer to the Consolidated
Financial Statements and footnotes of Donlar Corporation and subsidiaries for
the year ended December 31, 2001 contained elsewhere in this information
statement/prospectus.

     In management's opinion, the unaudited condensed consolidated financial
statements include all adjustments, consisting only of normal recurring
adjustments except as discussed below, which the Company considers necessary for
a fair presentation of the results for the period. Operating results for the
period presented are not necessarily indicative of the results that may be
expected for the entire year.

     The accompanying unaudited condensed consolidated financial statements have
been prepared assuming that the Company will continue as a going concern. As of
September 30, 2002, the Company had an accumulated deficit of $148,631,834, a
shareholders' deficit of $36,180,473 and has had substantial recurring losses.
The consolidated operations of the Company have not achieved profitability and
the Company has relied upon financing from the sale of its equity securities,
liquidation of assets and debt financing to satisfy its obligations. These
conditions raise substantial doubt about the ability of the Company to continue
as a going concern. The unaudited condensed consolidated financial statements do
not include any adjustments that might result from the outcome of these
uncertainties.

     The Company's ability to continue as a going concern is subject to the
attainment of profitable operations or obtaining necessary funding from outside
sources. Management's plan with respect to this uncertainty includes
reorganizing the Company and converting debt to equity, increasing sales of
existing products to attempt to maintain a positive cashflow, evaluating new
products and markets, and minimizing overhead and other costs. However, there
can be no assurance that management will be successful.

EQUITY TRANSACTIONS

     In January 2001, Donlar sold 1,500,000 shares of its common stock to an
investor for $714,593.

     In January 2001, the Company entered into an agreement with a media
relations firm. This agreement was for a period of one year, and the Company
issued the firm a warrant to purchase 1,250,000 shares of common stock of the
Company's subsidiary, Donlar Biosyntrex Corporation ("Donlar Biosyntrex"), at an
exercise price of $0.01 per share. This warrant could only be exercised if, in
the Company's opinion, the media relations firm satisfied its obligations under
the agreement. This agreement and the warrant were cancelled in April 2001 when
the Company entered into a new agreement effective January 20, 2001 with the
same media relations firm. The term of the new agreement is one year and the
Company issued 500,000 shares of Donlar Biosyntrex common stock to the media
relations firm in connection with the execution of the agreement. The Company
recorded $468,750 of general and administrative expenses upon the execution of
the agreement, which is the fair value of the stock issued as of that date.
Additionally, in April 2001, the Company issued the media relations firm 750,000
shares of Donlar Biosyntrex common stock which are being held in an escrow
account by the media relations firm until satisfaction of the terms of the
agreement. The fair value of these 750,000 shares was recorded as deferred
expense in the amount of $703,125, representing the fair market value of the
shares as of the date of the agreement, January 20, 2001. This amount was being
amortized over one year, the life of the agreement, as adjusted for changes in
fair value over the term of the agreement. The Company believes that the
conditions for release of the 750,000 shares from escrow have not been satisfied
by the media relations firm and the Company has requested return of the shares.

                      DONLAR CORPORATION AND SUBSIDIARIES

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In March 2001, an investment advisor exercised a warrant to purchase
400,000 shares of Donlar Biosyntrex common stock for $0.01 a share, pursuant to
its August 2000 agreement with the Company.

     In March 2002, the Company issued 2,000,000 shares of Donlar Biosyntrex
common stock to the same investment advisor in satisfaction of a two year
agreement, under which the advisor was entitled to $15,000 per month for 24
months. This agreement was terminated after fifteen months, and in lieu of
additional payments under the agreement, the Company issued to the investment
advisor 2,000,000 shares of Donlar Biosyntrex common stock in full satisfaction
of the Company's obligations to the advisor under the agreement. The fair value
assigned to the shares was $0.40 per share, the closing price of the shares at
the date of the agreement, for consulting expense of $800,000.

     In February 2002, the Company issued a total of 1,000,000 shares of Donlar
Biosyntrex common stock to two investor relations firms as payment for services
rendered pursuant to agreements with these firms. The fair value assigned to the
shares was $0.40 per share, the closing price of the shares at the date of the
agreement, for consulting expense of $400,000.

     Prior to January 1, 2000, Donlar issued 18,717,354 shares of Series A
Preferred stock in excess of the authorized shares of that class of stock. To
eliminate the over-issuance, in June 2002, two shareholders of the Company who
are directors agreed to exchange 18,717,354 shares of Series A Preferred stock
of Donlar owned by them for an equal number of shares of common stock of Donlar.
The shares were exchanged on a one for one basis.

DEBT TRANSACTIONS

     In the first quarter of 2002, the Company began implementing a plan which
is intended to significantly restructure its debt and capital structures in
order to eliminate a substantial portion of its debt and to ultimately result in
the merger of Donlar and Donlar Biosyntrex (the "Restructuring Plan"). The
Restructuring Plan is scheduled to be completed in October 2002.

     As part of the Restructuring Plan, on March 18, 2002, the Company entered
into a Bridge and Consolidated Term Loan Agreement with Tennessee Farmers Life
Insurance Company (the "Loan Agreement"). Pursuant to the terms of the Loan
Agreement, the Company obtained a bridge loan facility in the amount of
$2,127,000 to be used to refinance certain short term debt, provide working
capital, pay certain accounts payable creditors and pay expenses of the
transaction.

     In addition, the terms of existing loans to the Company in the original
principal amount of approximately $17.64 million were restated to the total
amount of $19.20 million, reflecting the original amount of the loans and
accrued, unpaid interest thereon (the "Restated Loans"). Each of the loans is
collateralized by substantially all of the assets of the Company.

     Loans under the bridge loan facility bear interest at a rate of eleven
percent (11%) per annum with one half of such interest payable on a quarterly
basis on the last business day of March, June, September and December and the
other half payable at maturity on March 18, 2003.

     The Restated Loans are divided into two loans. The first such loan is in
the principal amount of approximately $10.18 million, bears interest at a rate
of nine percent (9%) per annum until March 18, 2003, at which time such interest
is payable, and thereafter bears interest at eleven percent (11%) per annum
payable on a quarterly basis on the last business day of March, June, September
and December. The principal balance of the loan is payable in equal quarterly
installments of not less than $222,500 commencing on March 31, 2003 and
thereafter on the last business day of March, June, September and December. Any
remaining unpaid principal and interest is payable on March 31, 2007. The second
such loan is in the principal amount of $9.0 million, bears interest at a rate
of one percent (1%) per annum, but neither interest nor principal is payable
until the first to occur of one of certain events described in the Loan
Agreement, the latest of which is

March 18, 2005, after which time the interest that has accrued is payable in
full within thirty (30) days and thereafter is payable quarterly on the last
business day of March, June, September and December together with principal
payments of not less than $222,500. Any remaining unpaid principal and interest
is payable on March 31, 2007.


     As a condition of the loans and as part of the Restructuring Plan, Donlar
and Donlar Biosyntrex have agreed to use their best efforts to merge on or
before July 7, 2002 (the "Merger"). The date for completion of the Merger has
been extended to February 28, 2003. The merged company is referred to as the
Combined Company. In the Merger, each share of Donlar Biosyntrex common stock
other than shares owned by Donlar will be exchanged for 0.26 shares of the
common stock of the Combined Company. As a result of the Merger and related
transactions described herein, Donlar Biosyntrex's shareholders (other than
Donlar) will collectively receive approximately 4.0 million shares of the
Combined Company common stock representing approximately 19.5% of the shares of
common stock of the Combined Company outstanding following the Merger and
approximately 4.4% of the shares of common stock on a fully diluted basis. The
Merger requires the approval of a majority of the respective shareholders of
Donlar and Donlar Biosyntrex.


     The Company also made numerous representations, warranties and covenants in
the Loan Agreement. Among the covenants, the Company agreed to limit its ability
to incur additional indebtedness, make any investments or loans, pay dividends,
purchase, redeem or issue capital stock or sell or encumber assets. In addition,
the Company agreed to sell or discontinue the nutritional and nutraceuticals
business on or before March 18, 2003.

     There can be no assurance that the Company will be able to comply with the
covenants and events of default in the Loan Agreement, some of which events of
default are entirely beyond its control. Each of the loans made or restated
pursuant to the Loan Agreement is subject to acceleration and the application of
higher default rates of interest in the event the Company defaults in the
payment of principal or interest when due, breaches any covenants contained in
the Loan Agreement that are not remedied within five calendar days or any other
specified event of default occurs.

     Each of the loans is convertible at the option of the holder at any time
prior to repayment into common stock of Donlar Biosyntrex and, subsequent to the
Merger, into common stock of the Combined Company. Loans made under the bridge
loan facility convert into the Combined Company common stock at a rate of one
share per $0.29 of outstanding principal amount of the loans. The Restated Loans
convert into the Combined Company common stock at a rate of one share per $0.68
of outstanding principal amount of the loans. The conversion rates are subject
to antidilution protection. The holders of the loans have certain registration
rights with respect to the shares issuable upon conversion.

     In the first quarter of 2002, the Company also reached agreements with
Willis Stein and Partners, L.P. and Star Polymers, L.L.C. (collectively the
"Willis Stein Group") to (i) exchange $9.0 million of original principal amount
of notes plus accrued interest for shares of a new series of senior convertible
preferred stock with a stated liquidation value of $9.0 million and convertible
into approximately 13.23 million shares of the Combined Company common stock and
(ii) exchange all of the equity securities held by the Willis Stein Group in
Donlar for 1.0 million shares of the Combined Company common stock. The
foregoing exchanges are subject to the satisfaction of certain conditions
precedent. The Willis Stein Group also agreed to vote its shares of voting stock
of Donlar in favor of the Merger.

     The Company also reached an agreement in 2002 with Dr. Robert Gale Martin
("Martin"), a director of the Company, to (i) exchange approximately $9.9
million of original principal amount of notes plus accrued interest for shares
of senior convertible preferred stock with a stated liquidation value of $9.0
million and convertible into approximately 13.23 million shares of the Combined
Company common stock, (ii) relinquish rights to receive royalty payments from
the Company and all of his equity securities in the Company in exchange for 5.0
million shares of the Combined Company common stock and (iii) surrender for
cancellation

                      DONLAR CORPORATION AND SUBSIDIARIES

any warrants to purchase shares of Donlar common stock for a warrant to purchase
3.0 million shares of the Combined Company common stock at an exercise price of
$0.68 per share. Martin also agreed to vote his shares of voting stock of Donlar
in favor of the Merger.

     To further eliminate debt from the Company's balance sheet, the Company has
reached agreement with the holders of convertible notes issued in 1998 and 2000
in the approximate principal amount of $1.9 million, to exchange those notes for
shares of senior convertible preferred stock with a stated liquidation value
equal to the total principal amount of the notes. The senior convertible
preferred are convertible into approximately 2.8 million shares of the Combined
Company common stock.

     In the first quarter of 2002, the Company recorded a debt conversion
expense of $289,655 in connection with the bridge loan transaction. This debt
conversion expense was incurred as a result of the price for converting the
bridge loan into Donlar Biosyntrex common stock of $0.29 per share being below
the market price of the Donlar Biosyntrex common stock as of the date of the
loan agreement, which was $0.33 per share.

     The Restated Loans are convertible at a rate of $0.68 per share into common
stock of the Combined Company. The Restated Loans meet the criteria for new
debt. Because there are no induced conversion features associated with the
transaction, no beneficial conversion expense was recorded.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors and Shareholders
Donlar Corporation

     We have audited the consolidated balance sheet of Donlar Corporation and
Subsidiaries as of December 31, 2001, and the related consolidated statements of
operations, shareholders' deficit and cash flows for the years ended December
31, 2001 and 2000. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
consolidated financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Donlar Corporation and Subsidiaries as of December 31, 2001, and the
consolidated results of their operations, shareholders' deficit and cash flows
for the years ended December 31, 2001 and 2000, in conformity with accounting
principles generally accepted in the United States of America.

     The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in note
B to the consolidated financial statements, the Company has had substantial
recurring losses from operations, liquidation of assets and debt financing and
has relied upon financing from the sale of its equity securities to satisfy its
obligations. These conditions raise substantial doubt about the ability of the
Company to continue as a going concern. Management's plans in regard to this
matter are also described in note B. The consolidated financial statements do
not include any adjustments that might result from the outcome of this
uncertainty.

     As discussed in note R, the accompanying consolidated financial statements
for the years ended December 30, 2001 and 2000, have been restated.

                      DONLAR CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 2001 AND 2000

NOTE A -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     Donlar Corporation ("Donlar") and subsidiaries (collectively the "Company")
are in the early commercialization stage of a new family of environmentally
friendly biodegradable polymers, known as thermal polyaspartates ("TPA"). The
Company manufactures and markets these polymers to agricultural, industrial and
consumer markets. In the agricultural market, the products increase a plant's
ability to absorb nutrients more efficiently. In the industrial and consumer
markets, the products replace nonbiodegradable chemicals, and have been focused
toward the oil field production, water treatment, detergents and cleaners, and
personal care fields. The Company markets these products to service companies
and distributors in the United States of America and Europe.

     The Company also is engaged in the distribution and sale of biologic
nutraceutical supplements. Certain of the nutraceutical supplements incorporate
a patented whey protein technology licensed by the Company and designed to
provide or increase protective immunities to disease and to provide nutritional
supplementation. Nutraceutical products are food supplements that are derived
from a food base and are marketed as a beneficial source of nutrients to promote
good health. The Company sells these products primarily to nutritional companies
located in the United States of America. The Company has discontinued these
nutraceutical operations during 2002. Revenues generated from nutraceutical
products were approximately $300,000 and $180,000 during 2001 and 2000,
respectively.

 PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of Donlar's
68%-owned subsidiaries, Donlar Biosyntrex Corporation ("Donlar Biosyntrex") and
Optim Nutrition, Inc. and Donlar's 90%-owned subsidiary, Donlar Pharmaceutical
Corporation. All significant intercompany balances and transactions have been
eliminated. Minority interest in the majority owned subsidiaries is not shown,
as the entities have negative equity balances.

 USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

 INVESTMENT IN EQUITY SECURITIES

     The Company's investment in equity securities is carried in the financial
statements at the lower of cost or fair market value. Realized gains and losses,
determined using the specific identification method, are included in earnings.
At December 31, 2001, the Company wrote down to fair market value certain equity
security investments. The write down amounted to $864,434 and was due to a
decline in fair value considered to be other than temporary.

 FAIR VALUE OF FINANCIAL INSTRUMENTS

     The Company estimates that the fair value of all financial instruments at
December 31, 2001, does not differ materially from the aggregate carrying values
of its financial instruments recorded in the accompanying balance sheet. The
estimated fair value amounts have been determined by the Company using available
market information and appropriate valuation methodologies. Considerable
judgment is required in interpret-

                                       F-6

                      DONLAR CORPORATION AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

ing market data to develop the estimates of fair value and, accordingly, the
estimates are not necessarily indicative of the amounts that the Company could
realize in a current market exchange.

 INVENTORIES

     Inventories are stated at the lower of cost or market value, using the
first-in, first-out method.

 PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are stated at cost less accumulated
depreciation. Depreciation and amortization are determined using the
straight-line method over the estimated useful lives of the assets. Expenditures
for maintenance and repairs are expensed when incurred and betterments are
capitalized. Gains and losses on sale of property and equipment are reflected in
operations.

     The Company assesses the recoverability of its property, plant and
equipment whenever adverse events or changes in circumstances or business
climate indicate that expected future undiscounted cash flows or the fair value
may not be sufficient to support recorded property, plant and equipment. If
impairment exists, the carrying amount of property, plant and equipment will be
reduced by the shortfall.

 PATENTS AND OTHER ASSETS

     Patents are stated at cost less amortization computed on the straight-line
method, principally over 10 years. These costs include legal fees and
registration fees associated with the patents. The amount capitalized as patents
was approximately $2,807,000 at December 31, 2001. Accumulated amortization
related to patents and other assets was $911,000, at December 31, 2001.

 EARNINGS PER COMMON, COMMON EQUIVALENT AND REVERSE STOCK SPLITS

     The computation of basic earnings per common share is based on the weighted
average number of common shares outstanding during the year.

     The computation of diluted earnings per common share is based on the
weighted average number of common shares outstanding during the year plus common
stock equivalents, which would arise from the exercise of stock options and
warrants outstanding using the treasury stock method and the average market
price per share during the year. Common stock equivalents are not included in
the diluted earnings per share calculation when their effect is anti-dilutive.

     Preferred stock dividends and the impact of beneficial conversion premiums
increase the net loss attributable to common shareholders for purposes of
computing the net loss per common share.

     10,278,000 potentially dilutive shares were excluded from the diluted per
share calculation because their effect was anti-dilutive.

 REVENUE RECOGNITION

     In accordance with SAB 101, sales of product are recognized upon shipment
of the product, which is when title transfers to the customer. The Company
maintains reserves for potential losses on receivables from its customers, and
such losses have generally not exceeded management's expectations. The Company
maintains reserves for returns and allowances from its customers, and such
amounts have not exceeded management's expectations. Revenue by product type for
the years ended December 31, 2001 and 2000 was: Agricultural -- $238,935 and
$307,073; Biopolymer -- $1,812,331 and $890,489; and Nutriceutical -- $301,568
and $184,433.

                      DONLAR CORPORATION AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

 RESEARCH AND DEVELOPMENT EXPENSES

     Research and development expenses include amounts paid to third-party and
related-party consultants related to the Company's product research and
development activities. Costs associated with research and development of new
products are expensed as incurred.

 ADVERTISING

     The Company expenses the cost of advertising when the advertising occurs.
For the years ended December 31, 2001 and 2000, advertising expenses totaled
approximately $92,000 and $216,000, respectively, and are included in other
general and administrative expenses in the accompanying statements of
operations.

 INCOME TAXES

     The Company recognizes deferred income tax assets or liabilities for the
expected future tax consequences of events that have been recognized in the
financial statements or tax returns. Under this method, deferred income tax
assets or liabilities are determined based upon the difference between the
financial statement and income tax bases of assets and liabilities using enacted
tax rates expected to apply when differences are expected to be settled or
realized.

 ACCOUNTING FOR STOCK-BASED COMPENSATION

     The Company has elected to follow Accounting Principles Board Opinion No.
25 ("APB 25"), "Accounting for Stock Issued to Employees," in accounting for its
employee stock options. The Company has adopted the disclosure-only provisions
of Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting for
Stock-based Compensation." Under APB 25, because the exercise price of the
Company's employee stock options approximates the market price of the underlying
stock on the date of grant, no compensation expense is recognized. The expense
associated with stock options and warrants issued to non-employees and
non-directors is reflected in the consolidated financial statements in
accordance with SFAS 123. As permitted by SFAS 123, the intrinsic value of
compensatory options is reflected in the consolidated financial statements in
accordance with APB 25.

 CONCENTRATION OF CREDIT RISK

     Financial instruments which potentially subject the Company to
concentration of credit risk consist primarily of receivables. In the normal
course of business, the Company provides credit terms to its customers.
Accordingly, the Company performs ongoing credit evaluations of its customers
and maintains allowances for possible losses which, when realized, have been
within the range of management's expectations.

     The Company maintains its cash in bank deposit accounts, which may, at
times, exceed federally insured limits. The Company has not experienced any
losses in such accounts and believes it is not exposed to any significant credit
risk on cash and cash equivalents.

 NEW ACCOUNTING PRONOUNCEMENTS

     SFAS 141 "Business Combinations" and SFAS 142 "Goodwill and Other
Intangible Assets" -- On June 29, 2001, the Financial Accounting Standards Board
("FASB") approved for issuance SFAS 141, "Business Combinations," and SFAS 142,
"Goodwill and Other Intangible Assets." The FASB issued these Statements on July
20, 2001. Major provisions of these Statements include the following:

     - All business combinations initiated after June 30, 2001, must use the
       purchase method of accounting. The pooling method of accounting is
       prohibited except for transactions initiated before July 1, 2001.

                      DONLAR CORPORATION AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     - Intangible assets acquired in a business combination must be recorded
       separately from goodwill if they meet explicit criteria in SFAS 141.

     - Any negative goodwill remaining after reducing the carrying value of
       certain acquired assets to zero is recognized as an extraordinary gain.

     - SFAS 141 provisions relating to the initial measurement and recording of
       goodwill and intangible assets, as well as financial statement
       disclosures, are effective for purchase business combinations completed
       after June 30, 2001.

     - Goodwill and those intangible assets that have indefinite lives are not
       amortized but are tested for impairment annually and whenever there is an
       impairment indicator. In certain circumstances, goodwill impairment
       testing need not be done annually. All acquired goodwill must be assigned
       to reporting units for purposes of impairment testing.

     - SFAS 142 is effective for fiscal years beginning after December 15, 2001.
       Early adoption is permitted for companies with fiscal years beginning
       after March 15, 2001, but only if they have not issued their first
       quarter financial statements prior to adoption. Regardless of the full
       adoption date, the nonamortization provisions of SFAS 142 are effective
       for business combinations and other transactions completed after June 30,
       2001.

     - The Statements also include guidance on financial statement presentation
       and disclosures.

     Management does not expect these pronouncements will have an impact on the
2002 financial statements.

     SFAS 143 "Accounting for Asset Retirement Obligations" -- SFAS 143 states
that a liability for an asset retirement obligation should be recognized if the
obligation meets the definition of a liability in the FASB Concepts Statement 6,
"Element of Financial Statements," and if the amount of the liability can be
reasonably estimated. Consequently, an entity should recognize a liability for
an asset retirement obligation if (a) the entity has a duty or responsibility to
settle an asset retirement obligation, (b) the entity has little or no
discretion to avoid the future transfer or use of assets, and (c) the
transaction or other events obligating the entity has occurred. When a
retirement obligation is initially recognized, the asset retirement cost is
capitalized by increasing the carrying amount of the related long-lived asset by
an amount equal to the liability.

     The initial asset retirement obligation should be recorded at fair value.
Subsequent to the initial measurement, an entity should recognize changes in the
amount of the liability resulting from both the passage of time and revisions to
either the timing or amount of the estimated cash flows.

     SFAS 143 is effective for financial statements issued for fiscal years
beginning after June 15, 2002.

     Management does not expect this pronouncement will have an impact on the
2002 financial statements.

     SFAS 144 "Impairment or Disposal of Long-Lived Assets" -- was issued to
address significant implementation issues related to SFAS 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of," and to develop a single accounting model to account for long-lived assets
to be disposed of. SFAS 144 supersedes SFAS 121 as well as the provisions of
Opinion 30, Reporting the Results of Operations -- Reporting the Effects of
Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently
Occurring Events and Transactions, that address the disposal of a segment of a
business. SFAS 144 also amends ARD 51, Consolidated Financial Statements, to
eliminate the exception to consolidate a subsidiary for which control is likely
to be temporary.

     SFAS 144 carries over the recognition and measurement provisions in SFAS
121. Accordingly, an entity should recognize an impairment loss if the carrying
amount of a long-lived asset or asset group (a) is not

                                       F-9

                      DONLAR CORPORATION AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

recoverable, and (b) exceeds its fair value. SFAS 144 requires an entity to test
an asset or asset group for impairment whenever events or changes in
circumstances indicate that its carrying amount may not be recoverable. SFAS 144
also provides guidance on using the probability-weighted approach or the best-
estimate approach in developing estimated future cash flows to test
recoverability.

     Unlike SFAS 121, SFAS 144 includes criteria that have to be met for an
entity to classify a long-lived asset or asset group as held for sale. If the
criteria to classify an asset as held for sale are met after the balance sheet
date but before issuance of the financial statements, the asset group would
continue to be classified as held and used in those financial statements when
issued. The measurement of a long-lived asset or asset group classified as held
for sale is at the lower of its carrying amount or fair value less cost to sell.
Expected future losses associated with the operations of a long-lived asset or
asset group classified as held for sale are excluded from that measurement.

     SFAS 144 is effective for financial statements issued for fiscal years
beginning after December 15, 2001, and interim periods within those fiscal
years.

     Management does not expect this pronouncement will have an impact on the
2002 financial statements.

NOTE B -- GOING CONCERN

     The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As of December 31,
2001, the Company had an accumulated deficit of $136,441,923, a shareholders'
deficit of $30,298,463 and has had substantial recurring losses. The
consolidated operations of the Company have not achieved profitability and the
Company has relied upon financing from the sale of its equity securities,
liquidation of assets and debt financing to satisfy its obligations. These
conditions raise substantial doubt about the ability of the Company to continue
as a going concern. The consolidated financial statements do not include any
adjustments that might result from the outcome of these uncertainties.

     The Company's ability to continue as a going concern is subject to the
attainment of profitable operations or obtaining necessary funding from outside
sources. Management's plan with respect to this uncertainty includes
reorganizing the Company and converting debt to equity, increasing sales of
existing products to attempt to maintain a positive cash flow, evaluating new
products and markets, and minimizing overhead and other costs. However, there
can be no assurance that management will be successful.

NOTE C -- ACQUISITION

     On August 7, 2000, Donlar entered into an agreement with Donlar Biosyntrex
to purchase 427,311 shares of Donlar Biosyntrex common stock, approximately
19.9% of the outstanding shares, in exchange for a $1,115,025, 10% note due
December 31, 2000. On November 3, 2000, Donlar and Donlar Biosyntrex amended
this agreement. The restructured transaction took place in three phases. First,
Donlar Biosyntrex completed a 1 for 5 reverse split of its common stock.
Secondly, Donlar paid $563,500 in cash as a partial payment on the $1,115,025
note and received 1,127,000 shares of Donlar Biosyntrex common stock.

     Thirdly, Donlar transferred the exclusive right to distribute and the
exclusive right to all future sales from Donlar's crop nutrition management and
oil field products to Donlar Biosyntrex. Donlar Biosyntrex also received the
rights to certain research and development activities of Donlar and $1,850,000
in cash in exchange for issuing 40,152,520 additional shares of Donlar
Biosyntrex common stock to Donlar, so that upon completion of these
transactions, Donlar owned 96% of Donlar Biosyntrex common stock. Donlar also
agreed to transfer to Donlar Biosyntrex the balance of its assets and related
liabilities, except for Donlar's existing patent rights and all intellectual
property relating to Donlar's genetic research activities.

                                       F-10

                      DONLAR CORPORATION AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The foregoing transactions represent a change in control of Donlar
Biosyntrex since Donlar Corporation acquired 96% of Donlar Biosyntrex common
stock and Donlar Corporation's senior management and Board of Directors
succeeded to the same positions at Donlar Biosyntrex. Therefore, the transaction
has been accounted for as a reverse acquisition by Donlar Biosyntrex but as a
purchase by Donlar. For the year ended December 31, 2000, these financial
statements include the activity of Donlar, and also include the activity of
Donlar Biosyntrex subsequent to the date of acquisition, (November 3, 2000
through December 31, 2000). The fair value of the Donlar Corporation assets and
businesses transferred to Donlar Biosyntrex was deemed to be more clearly
evident than the fair value of the Donlar Biosyntrex business acquired by Donlar
Corporation. The measure of the fair value of the Donlar Corporation assets and
businesses in this case was 4% of the value of Donlar Corporation's stock. This
was based on the amount of control Donlar Corporation gave up in return for the
business operations of Donlar Biosyntrex. The fair value (4% of Donlar
Corporation) was based on Donlar equity transactions totaling 1,342,084 shares
all at $0.77 per share prior to the November 3, 2000 transaction. The purchase
price of Donlar Biosyntrex is considered to be the estimated fair value of 4% of
Donlar's stock, or $1,700,000, plus acquisition costs incurred of $338,953. In
determining the fair value assigned to Donlar Corporation shares in the purchase
price, the starting point used was a value of $0.77 per share for the common and
preferred shares. This is the price that the shares had been issued to
independent parties in 2000 and also the price at which much of the debt was
convertible. As of the date of the acquisition, Donlar had approximately
56,500,000 shares outstanding, resulting in approximately $43,550,000 in market
capitalization. Since Donlar shareholders gave up a 4% interest in substantially
all of Donlar's assets, the purchase price would be $43,550,000 * 4%, resulting
in a purchase price of approximately $1,700,000, the fair value used in the
acquisition. The acquisition price was allocated as follows:

     The acquisition was accounted for by the purchase method and the excess of
the acquisition price over the fair value of the assets acquired is accounted
for as goodwill and is being amortized over five years.

     Following is the summarized unaudited pro forma combined results of
operations for the year ended December 31, 2000, assuming the acquisition had
taken place at the beginning of the year. The unaudited pro forma results are
not necessarily indicative of future results or results that would have been
reported had the acquisition been completed when assumed.

</Table>

     During 2001, the Company determined its goodwill was impaired. This was due
to negative cash flows from the above-mentioned acquisition and the decrease in
revenue from the product lines included in the purchase. This impairment was
$1,189,923 for the year ended December 31, 2001, and goodwill was reduced to
zero.

     In 2000, the Company issued a note to Dr. Robert G. Martin, a director and
shareholder, in the amount of $3,000,000. This note bears interest at prime plus
2% (6.75% at December 31, 2001) and had a maturity date of April 30, 2001. The
note was amended and now has a maturity date of October 31, 2002. In connection
with that transaction, Donlar issued Dr. Martin a warrant to purchase shares of
its common stock at $0.01 a share. The total number of shares subject to the
warrant is equal to 15% of the total common stock of Donlar (19,558,320 shares)
and will be increased to 30% of the total common stock if the note is not paid
in full at the maturity date. This warrant has an expiration date of December
31, 2006. The value of the warrant on the date of issuance was $14,864,323,
computed using the Black-Scholes option pricing method. The $3,000,000 proceeds
were allocated to the note ($503,798) and paid-in capital for the warrant
($2,496,202) based on the relative fair value of securities issued. The related
debt discount associated with the warrant is being amortized over the life of
the Note, and recognized as interest expense.

     In 1996, Donlar received $26,000,000 from the venture capital shareholders
in exchange for (a) unsecured notes payable, which are convertible into shares
of Donlar Series A and B preferred stock, (b) Series C preferred stock of
Donlar, (c) shares in one of the Donlar's subsidiaries, (d) warrants to purchase
common stock of Donlar and (e) future royalty payments. The proceeds were
allocated to the equity instruments and liabilities based upon estimated fair
market value as follows. The fair value of the expected stream of royalty
payments was estimated to be $3,500,000. The Series C preferred stock's primary
feature was voting rights. The stock had no liquidation preference or redemption
or conversion features, nor did it provide for dividends. Since this stock had
only minimal value, a nominal $1,000 was estimated to be the fair market value.
The shares of Donlar's subsidiary were assigned a value of $1,000, since the
subsidiary had no operations and was subsequently dissolved. The value of the
warrants was estimated to be zero since they were performance-based warrants,
which management estimated would not be exercisable based on projections. The
face amount of the convertible notes was $26,000,000. A debt discount totaling
$3,502,000 was recorded and was amortized over the three-year period of the
related debt.

     The convertible notes contained an automatic conversion provision. In 1997,
holders of convertible notes aggregating $4,000,000 (face amount) surrendered
their notes following a notice and request by Donlar for conversion. In 1999,
the holders of the notes aggregating $22,000,000 entered into a settlement
agreement with Donlar, under the terms of which (a) Donlar paid the note holders
$8 million in cash and $9 million in 10% seven-year notes, (b) the warrants,
royalty rights and Donlar's Series B and C preferred stock held by the note
holders were cancelled, and (c) the convertible notes were converted into
20,278,456 shares of Donlar Series A preferred stock. These convertible note
holders are entitled to receive one share of Donlar's common or Series A
preferred stock for every three shares of common or Series A preferred stock
issued by Donlar in

the future as a result of the exercise or conversion of options, warrants and
convertible debt of Donlar outstanding at December 31, 1999, with exercise or
conversion prices greater than $1.00 per share.

     Dr. Martin deposited into an escrow account $1,000,000, which was paid to
holders of convertible notes in connection with the 1999 settlement described
above. In exchange for the $1,000,000, Donlar issued to Dr. Martin a one-year
unsecured note, bearing interest at 10%, due on December 31, 2000, and a
seven-year warrant to purchase 4,347,826 shares of Donlar Series A preferred
stock at $0.23 per share. The value of the warrant at the time of issuance was
$2,811,739, computed using the Black-Scholes option pricing method. The
$1,000,000 proceeds were allocated to the note ($262,348 net of debt discount)
and paid-in capital ($737,652) for the warrant based on the relative fair value
of the securities issued. The note was paid in full in 2000.

     In 1999, Donlar borrowed $5,131,507 from Dr. Martin, in exchange for a
$5,131,507, 11% note payable due on September 30, 2002. The note requires
quarterly interest only payments prior to the lump-sum principal repayment in
2002. The note is collateralized by a second lien on the patents held by Donlar.
These interest payments were not made in 2001. In connection with this
transaction, Donlar issued Dr. Martin seven-year warrants to purchase 12,000,000
shares of Donlar Series A preferred stock at $0.23 per share. The proceeds from
issuance of the note and warrants, $5,131,507, were allocated to the note
($2,052,603) and paid-in capital ($3,078,904) based on the relative fair values

     In 1998, Donlar received $763,500 from certain shareholders in exchange for
(a) 12% three-year notes convertible into Donlar Series A preferred stock at 90%
of the per share value of an initial public offering or a future equity
investment in Donlar of at least $15,000,000; and (b) ten-year warrants for
$763,500 in Donlar Series A preferred stock, exercisable at the per share value
of the next equity investment in Donlar of at least $15,000,000. A debt discount
of $551,000 recorded to reflect the value of the warrants is being amortized
over

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

a 36-month period beginning April 15, 1998. The number of shares into which the
notes are convertible is subject to a minimum such that, if necessary, at the
time of an initial public offering or the next equity investment in Donlar of at
least $15,000,000, the value of participating shareholders' shares, options and
warrants would be at least 150% of the shareholders' $2,763,586 basis in these
and prior investments.

     During 1997, Donlar borrowed $5,000,000 from a commercial bank
collateralized by a mortgage on Donlar's Peru, Illinois plant and equipment.
This transaction was supported by the commitment of a group of insurance
companies, which were shareholders of Donlar, to purchase the $5,000,000 note
and related mortgage from the bank. The note bore interest at 9.77% and required
quarterly interest only payments in 1998 and quarterly interest and principal
payments based on a 15-year amortization schedule for the next four years with
the remaining balance due on January 1, 2003. The loan was required to be repaid
on completion of an initial public offering with a 1% prepayment penalty if an
offering were completed in 1998.

     In 1998, the $5,000,000 note described in the preceding paragraph and
915,000 shares of Donlar Series A preferred stock owned by the group of
insurance companies (referred to above) were purchased by Donlar and
restructured into a 7% five-year note convertible into shares of Donlar common
stock at $5.00 per share or 85% of the per share value of a future public
offering or strategic equity investment in Donlar of at least $15,000,000. Cash
proceeds to Donlar were $1,400,000. Interest of $478,067 was recorded over the
seven-month period until the outstanding obligation equaled the face amount of
the note, $12,032,357, on February 1, 1999. Thereafter, Donlar was required to
make quarterly principal and interest payments on a 15-year amortization
schedule and a final balloon payment on April 1, 2003. The convertible note was
collateralized by all the tangible assets of the Company.

     With the agreement of the note holders referred to in the preceding
paragraph, the two $323,465 payments of principal and interest scheduled for
July 1 and October 1, 1999, were deferred until December 30, 1999, at which
time, Donlar and the note holder restructured the note, accrued interest and
late fees on the note as well as an additional $5,000,000 of cash proceeds to
Donlar, into a new $17,639,648 convertible note.

     The amended and restated note bears interest at 10% and requires quarterly
interest and principal payments based on a 15-year amortization schedule, with
the remaining balance due January 1, 2005. The note is convertible in whole or
in part into shares of Donlar Series A preferred stock at an exercise price of
$1.01 per share. The note is collateralized by all the Company's tangible and
intangible assets. In connection with the issuance of the note, Donlar granted
the insurance companies a 7-year warrant for the purchase of 6,025,171 shares of
Donlar common stock at an exercise price of $0.01 per share. The $5,000,000
proceeds were allocated to the note ($2,796,146) and paid-in capital
($2,203,854) based on the relative fair value of the securities issued.

     In 2000, Donlar received $1,767,000 from certain shareholders in exchange
for (a) five year 15% notes convertible into shares of Donlar Series A preferred
stock at $1.01 per share, or $0.505 per share in the event of an initial public
offering, and (b) five year warrants to purchase 773,062 shares of Donlar Series
A preferred stock at $0.01 per share. The cash proceeds were allocated to the
note and warrant based on the relative fair value of the securities issued. The
value of the warrants at the time of issuance was $587,527 calculated using the
Black Scholes option pricing model. The $1,767,000 proceeds were allocated to
the note ($1,326,079) and paid-in-capital for the warrants ($440,921) based on
the relative fair value of securities issued.

     In 2000, Dr. Martin paid $1,000,000 for (a) five year 15% note convertible
into shares of Donlar Series A preferred stock at $0.77 per share, or $0.385 per
share in the event of in initial public offering and (b) five year warrant to
purchase 4,069,262 shares of Donlar Series A stock at $0.01 per share. Dr.
Martin was also granted a 1% royalty on all Donlar sales for ten years. The cash
proceeds were allocated to the note, warrant and royalty obligation based on the
relative fair value of the securities issued and the present value of the
projected revenue stream. The value of the warrant at the time of issuance was
$3,092,639 calculated using the Black Scholes option pricing model. The
$1,000,000 proceeds were allocated to the note ($244,341) and paid-in-

capital for the warrant ($755,659) based on the relative fair value of
securities issued. An additional debt discount was recorded on this note because
of its beneficial conversion factor. This additional discount left the book
value of the note at $-0-.

     Another investor purchased for $150,000 a five year 12% note convertible
into shares of Donlar Series A preferred stock at $1.01 per share, or $.505 per
share in the event of an initial public offering.

     The Company's net operating loss carryforward benefit and valuation
allowance were reduced for the expiration of both the investment tax credit
carryforward and a portion of the net operating loss carryforward.

     As of December 31, 2000, the Company had net operating loss carryforwards
("NOL's") for Federal income tax reporting purposes of approximately
$55,000,000. These NOL's will expire over time between 2001

                                       F-16

                      DONLAR CORPORATION AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

through 2020. There can be no assurance that all of these NOL's will be
available to offset future taxable income, if any. An NOL generated in a
particular year will expire for Federal income tax purposes if not utilized
within 15 to 20 years, depending on when the NOL's were generated. Additionally,
the Internal Revenue Code contains other provisions, which could reduce or limit
the availability and utilization of these NOL's. For example, limitations are
imposed on the utilization of NOL's if certain ownership changes have taken
place. In accordance with SFAS No. 109, a valuation allowance is provided when
it is more likely than not that some portion of the deferred income tax asset
will not be realized. Due to the uncertainty with respect to the ultimate
realization of the NOL's, the Company has established a valuation allowance for
all of its deferred income tax assets.

     The Company could be subject to alternative minimum tax, which the NOL's
cannot be used to offset; however, an assessment has not yet been determined.

NOTE H -- GAIN ON SALE OF PRODUCT LINE

     In 2000, the Company's subsidiary sold its Nite Bite product line for
$1,482,000. A retention reserve of 10% was established in the amount of
$148,200. The retention reserve had an allowance booked against it at the date
Donlar Biosyntrex was acquired by Donlar. In 2001, the Company received the full
retention reserve, and a gain of $100,000 was recorded.

NOTE I -- COMMON AND PREFERRED STOCK

     Donlar's authorized common and preferred stock as of December 31, 2001 was
60,000,000 shares of common stock with no par value, and 38,000,000 shares of
preferred stock with no par value.

NOTE J -- EQUITY TRANSACTIONS

     In January 2001, Donlar sold 1,500,000 shares of its common stock to an
investor for $714,593. These shares were issued for cash.

     In January 2001, the Company entered into an agreement with a media
relations firm. This agreement was for a period of one year. The Company issued
the firm a warrant to purchase 1,250,000 shares of Donlar Biosyntrex common
stock at an exercise price of $0.01 per share. This warrant could only be
exercised if, in the Company's opinion, the media relations firm satisfied its
obligations under the agreement. This agreement and the warrant were cancelled
in April 2001 when the Company entered into a new agreement effective January
20, 2001 with the same media relations firm. The term of the new agreement was
one year and the Company issued 500,000 shares of Donlar Biosyntrex common stock
to the media relations firm in connection with the execution of the agreement.
The Company recorded $468,750 of general and administrative expenses which is
the fair value of the stock issued. These shares were issued in exchange for
services rendered. Additionally, the Company issued the media relations firm
750,000 shares of Donlar Biosyntrex common stock which are being held in an
escrow account by the media relations firm until satisfaction of the terms of
the agreement. The fair value of these 750,000 shares were recorded as deferred
compensation in the amount of $703,125. This amount was amortized over one year,
the life of the agreement, as adjusted for changes in fair value over the term
of the agreement. The Company believes that the conditions for the release of
the 750,000 shares to the media relations firm from escrow were not satisfied
and the Company has requested return of the shares.

     In March 2001, an investment advisor exercised a warrant to purchase
400,000 shares of Donlar Biosyntrex common stock for $0.01 a share, pursuant to
its August 2000 agreement with the Company. These shares were issued for cash.

     In April 2001, the Company entered into a management services agreement
with an investment advisor. In exchange for the services performed relating to
potential acquisitions, the Company issued 1,000,000 shares
                                       F-17

                      DONLAR CORPORATION AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

of Donlar Biosyntrex common stock to the investment advisor. The Company
recorded $1,230,000 in general and administrative expenses during April 2001
equal to the fair value of these shares. These shares were issued for services
rendered.

     On May 11, 2001, the Company issued a warrant to purchase 500,000 shares of
common stock at $2.50 a share to the investment advisor referred to above. In
connection with this transaction, the Company recorded $403,900 of general and
administrative expenses, which is the fair value of the warrant issued. The fair
value of the warrant is estimated using the Black-Scholes pricing model, with an
expected volatility of 145%, a risk-free interest rate of 5% and 0% dividend
yield. On June 6, 2001, this investment advisor partially exercised the warrant
to purchase 18,000 shares. This warrant was issued for services rendered and the
partial exercise of the warrant was done in cash.


     In November 2000, Donlar Biosyntrex issued and delivered 8,000,000 shares
of its common stock, representing approximately 17% of Donlar Biosyntrex, to a
shareholder and former director of Donlar so that he could pledge that stock to
a commercial bank as collateral for a loan. Donlar agreed to the surrender for
cancellation of 8,000,000 shares of Donlar Biosyntrex common stock held by
Donlar. The issuance of 8,000,000 shares by Donlar Biosyntrex and the surrender
by Donlar of 8,000,000 shares, together with other unrelated stock issuances by
Donlar Biosyntrex, increased the minority interest from 4% to 32%. Donlar
recognized a receivable from the former director and shareholder in connection
with the transfer of 8,000,000 shares in its subsidiary, Donlar Biosyntrex. The
receivable was recorded by Donlar Biosyntrex and Donlar at fair value,
$8,000,000. In June 2002, the former director and shareholder agreed to cancel
4,289,816 shares of Donlar stock held by him in satisfaction of the receivable.
The relationship of 8,000,000 shares to 4,289,816 is based on the exchange
ratios referred to in the discussion of the merger.



     The original issuance by Donlar Biosyntrex of the 8,000,000 shares of
common stock was recorded as a shareholder receivable at the fair value at the
date of issuance ($1.00 per share). The shareholder was deemed to be an
affiliate of Donlar Biosyntrex, and therefore, the receiveable was recorded as a
contra equity account. On August 13, 2001, in satisfaction of the receivable,
the shareholder surrendered all his shares of Donlar Corporation stock to Donlar
Corporation and Donlar Corporation surrendered 8,000,000 shares of Donlar
Biosyntrex common stock held by Donlar Corporation to Donlar Biosyntrex. The
surrender of shares has been recorded as an acquisition of Treasury Stock.
Donlar incurred a loss on the receivable of $5,360,000 because of the difference
in the fair value of the stock between the issue and the settlement date.


     Prior to January 1, 2000, Donlar in various transactions issued 14,369,528
shares of Series A Preferred stock in excess of the authorized shares of that
class of stock. To eliminate the over-issuance, two shareholders of the Company
who are directors agreed in 2002 to exchange 14,369,528 shares of Series A
Preferred stock of Donlar owned by them for an equal number of shares of common
stock of Donlar.

NOTE K -- STOCK OPTIONS AND WARRANTS

     When accounting for the issuance of stock options and warrants, financial
accounting standards allow entities the choice between adopting a fair value
method or an intrinsic value method with footnote disclosures of the pro forma
effects if the fair value method had been adopted. Donlar has opted for the
latter approach. Had Donlar options and warrants been determined based on the
fair value method, the results of operations would have been reduced to the pro
forma amounts indicated below:

NOTE O -- COMMITMENTS AND CONTINGENCIES

     In 1994, the Company entered into a licensing agreement with a shareholder
for the use of patent rights. The licensing agreement requires the Company to
pay $7,500,000 in cumulative royalties. Annual payments are based upon sales
volume except that minimum annual payments of $50,000 are required to be made
beginning year 2000. Royalty payments, as a percentage of sales, are 4% for the
first $2,000,000 in royalties, decreasing one percentage point to a floor of 1%
for each $2,000,000 in royalties paid until $7,500,000 in cumulative royalties
is paid. Royalty expense relating to this agreement was $9,557 and $10,874 for
the years ended December 31, 2001 and 2000, respectively. The amount accrued at
December 31, 2001, was approximately $163,000.

     The Company has an employment agreement with the President expiring on June
30, 2003, providing for minimum aggregate annual payments of $185,000 and
severance in the event of termination. Under the agreement, the President is
also eligible for cash and stock bonuses.

     The Company has an employment agreement with its chief operating officer
expiring on September 7, 2003, renewing for three additional years if certain
sales goals are met and providing for minimum aggregate annual payments of
$160,000 plus an automobile allowance and severance in the event of termination.
Under the agreement, the chief operating officer is also eligible for incentive
cash and stock bonuses.

     Donlar and the Vice President of Research of its subsidiary, Donlar
Pharmaceutical Corporation, entered into an agreement in May 1997, whereby
Donlar purchased certain patents relating to the use of polyaspartates in a wide
variety of allergic conditions. In return for those patents, the Vice President
was granted a 10% interest in Donlar Pharmaceutical Corporation and the right to
receive royalties on sales of products based on those patents at rates ranging
from 0.5% to 2.0%, to a maximum aggregate royalty of $10 million. No

value has been assigned to the acquired patents. The length of time involved in
realizing the value from a pharmaceutical patent makes such a valuation not
determinable.

 LITIGATION

     Because of the nature of its activities, the Company is subject to legal
actions, which arise in the normal course of business. In the opinion of
management, the disposition of any such matters would not have a material effect
on the consolidated financial position of the Company.

NOTE P -- SIGNIFICANT SOURCE OF REVENUES

     The Company had sales to certain customers that have accounted for at least
10% of the Company's net revenue. Revenues from external foreign customers
totaled $1,791,911 during 2001. Customer information is as follows for the years

NOTE Q -- SUBSEQUENT EVENTS

     On March 18, 2002, the Company entered into a bridge loan of $2.127
million. The loan agreement states proceeds are to be used to pay down certain
accounts payable and certain short-term debt, provide working capital and pay
for expenses related to the restructuring of the Company. The bridge loan bears
interest at 11% and has a maturity date of March 18, 2003. As a condition to
this new loan, the Company had to obtain approval of a debt restructuring from
some of its other noteholders.

     In addition, the terms of existing loans to the Company are expected to be
renegotiated to make the obligation total approximately $19,200,000, which will
reflect the original loans and accrued interest. The restated loans will be
divided into two loans. The first loan will have a principal balance of
$10,180,000, bears interest at 9%, until March 18, 2003, at which time interest
will be payable. Principal payments are to be made at $222,500 per quarter. Any
unpaid principal and interest will be due on March 31, 2007. The second loan
will have a principal balance of $9,000,000 and bear interest at 1%, no payments
of which will be required until March 31, 2005. Any unpaid principal and
interest will be due on March 31, 2007.

     Each of the loans will be convertible at the option of the holder into
common stock of Donlar Biosyntrex. The restated loans will convert at a rate of
one share per $0.68 of outstanding principal of the loans.

     In addition, two major debt holders will exchange approximately $18,800,000
of notes payable into convertible preferred stock.

     The restructuring plan calls for Donlar Biosyntrex to be merged into Donlar
during 2002. The shareholders of Donlar Biosyntrex will receive 0.26 shares of
Donlar common stock for each share of Donlar Biosyntrex.

     In connection with the restructuring plan, the Company has reached
agreements to issue 465,000 share of common stock of Donlar after the merger to
accounts payable and other creditors as payment for open payables and claims
against either Donlar or Donlar Biosyntrex. The issuances will result in an
adjustment to debt conversion expense of $92,400. The issuances of the shares
are contingent upon the merger.

NOTE R -- RESTATEMENT

     At December 31, 2000, debt discount, interest expense, net loss and per
share amounts have been adjusted from previously reported amounts to reverse
repayment of Donlar Corporation debt in the amount of $3,000,000 and the
exercise of warrants to purchase 19,559,432 common shares and 16,408,324
preferred shares of Donlar Corporation stock for a total exercise price of
$3,000,000. The transaction could not be completed due to the lack of authorized
shares. The financial statements have been corrected to reflect the unwinding of
the transaction. Net loss for 2000 was increased by $1,050,103 ($0.03 per
share).


     On November 27, 2002, the Company determined that the November 2000
issuance of 8,000,000 shares of common stock, which had been recorded at no
value, should have been recorded at $8,000,000, or $1.00 per share, offset by a
contra receivable in the same amount as discussed in Note J. Further, the
Company determined that the August 2001 surrender by the Company's shareholders
of 4,289,816 shares of the Company in satisfaction of the $8,000,000 receivable
resulted in a loss on the receivable of $5,360,000 because of the difference in
the fair value of the stock between the issue and the settlement date. The net

                                                                      APPENDIX B

                               DONLAR CORPORATION
                           2002 EQUITY INCENTIVE PLAN

1.  PURPOSE.

     The purpose of the Donlar Corporation 2002 Equity Incentive Plan (the
"Plan") is to enhance the ability of Donlar Corporation (the "Company") and any
subsidiaries to attract and retain the best available personnel for positions of
substantial responsibility, to provide additional incentive to such personnel
and to promote the success of the Company. To accomplish these purposes, the
Plan provides a means whereby employees, directors and consultants of the
Company and any of its subsidiaries may receive stock options to purchase shares
of the Company's Common Stock ("Options").

2.  ADMINISTRATION.

     (a) Composition of the Committee.  The Plan shall be administered by a
committee (the "Committee"), which shall be appointed by and serve at the
pleasure of the Company's Board of Directors (the "Board"). The Committee shall
be comprised of two or more members of the Board. In the event that the Company
registers any class of equity securities pursuant to Section 12 of the
Securities Exchange Act of 1934 (the "Exchange Act"), each member of the
Committee shall be (i) a "non-employee director" within the meaning of Rule
16b-3 under the Exchange Act, and (ii) an "outside director" within the meaning
of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code").
Subject to the foregoing, from time to time the Board may increase or decrease
the size of the Committee, appoint additional members thereof, remove members
(with or without cause), appoint new members in substitution therefor, fill
vacancies or remove all members of the Committee and thereafter directly
administer the Plan.

     (b) Authority of the Committee.  The Committee shall have full and final
authority, in its sole discretion, to interpret the provisions of the Plan and
to decide all questions of fact arising in its application; to determine the
employees, directors and consultants to whom awards shall be made and the type,
amount, size and terms of each such award; to determine the time when awards
shall be granted; and to make all other determinations necessary or advisable
for the administration of the Plan. The Committee shall have the authority to
adopt, amend and rescind such rules, regulations and procedures as, in its
opinion, may be advisable in the administration of the Plan, including, without
limitation, rules, regulations and procedures that: (i) deal with satisfaction
of an optionee's tax withholding obligations pursuant to Section 13 hereof, (ii)
include arrangements to facilitate an optionee's ability to borrow funds for the
payment of the exercise price of an Option, if applicable, from securities'
brokers and dealers, and (iii) include arrangements that provide for the payment
of some or all of an Option's exercise price by delivery of previously owned
shares of Common Stock or other property and/or by withholding some of the
shares of Common Stock being acquired upon exercise of an Option. All decisions,
determinations and interpretations of the Committee shall be final and binding
on all optionees and all other holders of Options granted under the Plan.

     (c) Authority of the Board.  Notwithstanding anything to the contrary set
forth in the Plan, all authority granted hereunder to the Committee may be
exercised at any time and from time to time by the Board. All decisions,
determinations and interpretations of the Board shall be final and binding on
all optionees and all other holders of Options granted under the Plan.

3.  STOCK SUBJECT TO THE PLAN.

     Subject to Section 16 hereof, the shares that may be issued under the Plan
shall not exceed in the aggregate 5,000,000 shares of Common Stock of the
Company (the "Common Stock"). Such shares may be authorized and unissued shares
or shares issued and subsequently reacquired by the Company. Except as otherwise
provided herein, any shares subject to an Option that for any reason expires or
is terminated unexercised as to such shares shall again be available under the
Plan.

                                       B-1


4.  ELIGIBILITY TO RECEIVE OPTIONS.

     Persons eligible to receive stock options under the Plan shall be limited
to those consultants to and those officers, directors and other employees of the
Company and any subsidiary (as defined in Section 425 of the Code or any
amendment or substitute thereto) who are in positions in which their decisions,
actions and counsel significantly impact upon the profitability and success of
the Company and/or a subsidiary. Moreover, consultants and directors who are not
also employees shall not be eligible to be awarded Incentive Stock Options (as
defined in Section 5 hereof).

5.  TYPES OF OPTIONS.

     Grants may be made at any time and from time to time by the Committee in
the form of stock options to purchase shares of Common Stock. Options granted
hereunder may be Options that are intended to qualify as incentive stock options
within the meaning of Section 422 of the Code or any amendment or substitute
thereto ("Incentive Stock Options") or Options that are not intended to so
qualify ("Nonqualified Stock Options").

6.  STOCK OPTIONS.

     Each Option for the purchase of Common Stock shall be evidenced by a
written option agreement in such form not inconsistent with the Plan as the
Committee shall approve from time to time. The Options granted hereunder may be
evidenced by a single agreement or by multiple agreements, as determined by the
Committee in its sole discretion. Each option agreement shall contain in
substance the following terms and conditions:

          (a) Type of Option.  Each option agreement shall identify the Options
     represented thereby as Incentive Stock Options or Nonqualified Stock
     Options, as the case may be.

          (b) Option Price.  Each option agreement shall set forth the purchase
     price of the Common Stock purchasable upon the exercise of the Option
     evidenced thereby. Subject to the limitation set forth in Section 6(d)(ii),
     the purchase price of the Common Stock subject to an Incentive Stock Option
     shall be not less than 100% of the Fair Market Value of such stock on the
     date the Option is granted, as determined by the Committee, but in no event
     less than the par value of such stock. The purchase price of the Common
     Stock subject to a Nonqualified Stock Option shall be not less than 85% of
     the Fair Market Value of the Common Stock on the date the Option is
     granted, as determined by the Committee. The Fair Market Value on any date
     shall mean the closing price of the Common Stock, as reported in The Wall
     Street Journal (or if not so reported, as otherwise reported by the
     National Association of Securities Dealers Automated Quotation ("Nasdaq")
     System), or if the Common Stock is not reported by Nasdaq, the fair market
     value shall be as determined by the Committee in accordance with Section
     422 of the Code.

          (c) Exercise Term.  Each option agreement shall state the period or
     periods of time within which the Option shall vest and may be exercised, in
     whole or in part, which shall be such a period or periods of time as may be
     determined by the Committee, provided that no Option shall be exercisable
     after ten years from the date of grant thereof. Subject to the requirements
     set forth in the Plan, the Committee shall have the power to permit: (i)
     the exercise of unvested Options, or portions thereof, for the purchase of
     shares of restricted Common Stock subject to a repurchase right in favor of
     the Company, with the repurchase price being equal to the lesser of (x) the
     original purchase price or (y) the Fair Market Value of the shares on the
     date of repurchase, or to any other restrictions as the Committee deems to
     be appropriate, and (ii) the acceleration of previously established
     exercise terms, in each case upon such circumstances and subject to such
     terms and conditions as the Committee shall determine.

          (d) Incentive Stock Options.  In the case of an Incentive Stock
     Option, each option agreement shall contain such other terms, conditions
     and provisions as the Committee determines necessary or desirable in order
     to qualify the Option granted thereunder as a tax-favored Option (within
     the meaning of Section 422 of the Code or any amendment or substitute
     thereto or regulation thereunder) including without limitation, each of the
     following, except that any of these provisions may be omitted or modified

                                       B-2


     if it is no longer required in order to have an Option qualify as a
     tax-favored Option within the meaning of Section 422 of the Code or any
     substitute therefor:

             (i) The aggregate Fair Market Value (determined as of the date the
        Option is granted) of the Common Stock with respect to which Incentive
        Stock Options are first exercisable by any employee during any calendar
        year (under all plans of the Company) shall not exceed $100,000.

             (ii) No Incentive Stock Options shall be granted to any employee if
        at the time the Option is granted such employee owns stock possessing
        more than 10% of the total combined voting power of all classes of stock
        of the Company or its parent or its subsidiaries unless at the time such
        Option is granted the Option price is at least 110% of the fair market
        value of the stock subject to the Option and, by its terms, the Option
        is not exercisable after the expiration of five years from the date of
        grant.

          (e) Substitution of Options.  Options may be granted under the Plan
     from time to time in substitution for stock options held by employees of
     other corporations who are about to become, and who do concurrently with
     the grant of such options become, employees of the Company or a subsidiary
     as a result of a merger or consolidation of the employing corporation with
     the Company or a subsidiary, or the acquisition by the Company or a
     subsidiary of the assets of the employing corporation, or the acquisition
     by the Company or a subsidiary of stock of the subsidiary. The terms and
     conditions of the substitute Options so granted may vary from the terms and
     conditions set forth in this Section 6 to such extent as the Committee at
     the time of grant may deem appropriate to conform, in whole or in part, to
     the provisions of the stock options in substitution for which they are
     granted.

7.  DATE OF GRANT.

     The date on which an Option shall be deemed to have been granted under the
Plan shall be the date of the Committee's authorization of the Option or such
later date as may be determined by the Committee at the time the Option is
authorized. Notice of the determination shall be given to each individual to
whom an Option is so granted within a reasonable time after the date of such
grant.

8.  EXERCISE AND PAYMENT FOR SHARES.

     Options may be exercised in whole or in part, from time to time, when
permitted by the respective option agreement, by giving written notice of
exercise to the Secretary of the Company, specifying the number of shares to be
purchased. The purchase price of the shares with respect to which an Option is
exercised shall be payable in full with the notice of exercise in cash, Common
Stock at Fair Market Value, or a combination thereof, as the Committee may
determine from time to time and subject to such terms and conditions as may be
prescribed by the Committee for such purpose. The Committee may also, in its
discretion and subject to prior notification to the Company by an optionee,
permit an optionee to enter into an agreement with the Company's transfer agent
or a brokerage firm of national standing whereby the optionee will
simultaneously exercise the Option and sell the shares acquired thereby through
the Company's transfer agent or such a brokerage firm and either the Company's
transfer agent or the brokerage firm executing the sale will remit the Company
from the proceeds of sale the exercise price of the shares as to which the
Option has been exercised.

9.  RIGHTS UPON TERMINATION OF SERVICE.

     In the event that an optionee ceases to be an employee or consultant of the
Company or any subsidiary for any reason other than death, retirement, as
hereinafter defined, or disability (within the meaning of Section 72(m)(7) of
the Code or any substitute therefor), the optionee shall have the right to
exercise the Option during its term within a period of three months after such
termination to the extent that the Option was vested and exercisable at the time
of termination, or within such other period and subject to such terms and
conditions as may be specified by the Committee; provided, however, that the
period during which an Incentive Stock Option may be exercised may not exceed
three months after the date of such termination. In the event that an optionee
dies, retires or becomes disabled prior to the expiration of his Option and
without having fully exercised his Option, the optionee or his successor shall
have the right to exercise the Option to
                                       B-3


the extent vested at the time he ceases to be an employee of the Company, during
its term within a period of one year after termination of employment due to
death, retirement or disability to the extent that the Option was exercisable at
the time of termination, or within such other period and subject to such terms
and conditions as may be specified by the Committee. As used in this Section 9,
"retirement" shall apply only to employees and not to consultants and means a
termination of employment by reason of an optionee's retirement at or after his
earliest permissible retirement date pursuant to and in accordance with his
employer's regular retirement plan or personnel practices.

10.  GENERAL RESTRICTIONS.

     Each Option granted under the Plan shall be subject to the requirement that
if at any time the Committee shall determine that (i) the listing, registration
or qualification of the shares of Common Stock subject or related thereto upon
any securities exchange or under any state or federal law, or (ii) the consent
or approval of any government regulatory body, or (iii) an agreement by the
recipient of an Option with respect to the disposition of shares of Common Stock
is necessary or desirable as a condition of or in connection with the granting
of such Option or the issuance or purchase of shares of Common Stock thereunder,
such Option shall not be consummated in whole or in part unless such listing,
registration, qualification, consent, approval or agreement shall have been
effected or obtained free of any conditions not acceptable to the Committee.

11.  RIGHTS OF A SHAREHOLDER.

     The recipient of any Option under the Plan, unless otherwise provided by
the Plan, shall have no rights as a shareholder unless and until a certificate
for shares of Common Stock is issued and delivered to him.

12.  RIGHT TO TERMINATE SERVICE.

     Nothing contained in the Plan or in any agreement entered into pursuant to
the Plan shall confer upon any optionee the right to continue in the service of
the Company or any subsidiary as an employee or a consultant or affect any right
that the Company or any subsidiary may have to terminate the employment or
consulting relationship of such optionee.

13.  WITHHOLDING.

     Whenever the Company proposes or is required to issue or transfer shares of
Common Stock under the Plan, the Company shall have the right to require the
recipient to remit to the Company an amount sufficient to satisfy any federal,
state or local withholding tax requirements prior to the delivery of any
certificate or certificates for such shares. If and to the extent authorized by
the Committee, in its sole discretion, an optionee may make an election, by
means of a form of election to be prescribed by the Committee, to have shares of
Common Stock that are acquired upon exercise of an Option withheld by the
Company or to tender other shares of Common Stock or other securities of the
Company owned by the optionee to the Company at the time of exercise of an
Option to pay the amount of tax that would otherwise be required by law to be
withheld by the Company as a result of any exercise of an Option from amounts
payable to such optionee. Any such election shall be irrevocable and shall be
subject to the disapproval of the Committee at any time. Any securities so
withheld or tendered will be valued by the Committee as of the date of exercise.

14.  NON-ASSIGNABILITY.

     No Option under the Plan shall be assignable or transferable by the
recipient thereof except by will or by the laws of descent and distribution or
by such other means as the Committee may approve. During the life of the
recipient such Option shall be exercisable only by such person or by such
person's guardian or legal representative.

15.  NON-UNIFORM DETERMINATIONS.

     The Committee's determinations under the Plan (including without limitation
determinations of the persons to receive Options, the form, amount and timing of
such grants, the terms and provisions of Options,
                                       B-4


and the agreements evidencing same) need not be uniform and may be made
selectively among persons who receive, or are eligible to receive, grants of
Options under the Plan whether or not such persons are similarly situated.

16.  ADJUSTMENTS.

     (a) Changes in Capitalization.  Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and the number of shares of Common Stock that have been
authorized for issuance under the Plan but as to which no Options have yet been
granted or which have been returned to the Plan upon cancellation or expiration
of an Option, as well as the price per share of Common Stock covered by each
such outstanding Option, shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
shares of Common Stock effected without receipt of consideration by the Company;
provided, however, that conversion of any convertible securities of the Company
shall not be deemed to have been "effected without receipt of consideration."
Such adjustment shall be made by the Committee, whose determination in that
respect shall be final, binding and conclusive. Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option.

     (b) Dissolution or Liquidation.  In the event of the proposed dissolution
or liquidation of the Company, all outstanding Options will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Committee. The Committee may, in the exercise of its sole
discretion in such instances, declare that any Option shall terminate as of a
date fixed by the Committee and give each Option holder the right to exercise
his Option as to all or any part of the shares of Common Stock covered by the
Option, including shares as to which the Option would not otherwise be
exercisable.

     (c) Sale or Merger.  In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, the Committee, in the exercise of its sole
discretion, may take such action as it deems desirable, including, but, not
limited to: (i) causing an Option to be assumed or an equivalent option to be
substituted by such successor corporation or a parent or subsidiary of such
successor corporation, (ii) providing that an Option holder shall have the right
to exercise his Option as to all of the shares of Common Stock covered by the
Option, including shares as to which the Option would not otherwise be vested or
exercisable, or (iii) declare that an Option shall terminate at a date fixed by
the Committee provided that the Option holder is given notice and opportunity
prior to such date to exercise that portion of his Option that is currently
vested and exercisable.

17.  AMENDMENT.

     The Board may terminate or amend the Plan at any time with respect to
shares as to which Options have not been granted, subject to any required
shareholder approval or any shareholder approval that the Board may deem to be
advisable for any reason, such as for the purpose of obtaining or retaining any
statutory or regulatory benefits under tax, securities or other laws or
satisfying any applicable stock exchange listing requirements. Neither the Board
nor the Committee may, without the consent of the holder of an Option, alter or
impair any Option previously granted under the Plan, except as specifically
authorized herein.

18.  CONDITIONS UPON ISSUANCE OF SHARES.

     (a) Compliance with Securities Laws.  Shares of the Company's Common Stock
shall not be issued pursuant to the exercise of an Option unless the exercise of
such Option and the issuance and delivery of such shares pursuant thereto shall
comply with all relevant provisions of law, including, without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the Common Stock of the Company may then be listed, and shall be further subject
to the approval of counsel for the Company with respect to such compliance.

                                       B-5


     (b) Investment Representations.  As a condition to the exercise of an
Option, the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the shares of Common Stock 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
representation is required by any of the aforementioned relevant provisions of
law.

19.  RESERVATION OF SHARES.

     The Company, during the term of the Plan, will at all times reserve and
keep available such number of shares as shall be sufficient to satisfy the
requirements of the Plan. Inability of the Company 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 in respect of the failure to issue or
sell such shares as to which such requisite authority shall not have been
obtained.

20.  EFFECT ON OTHER PLANS.

     Participation in the Plan shall not affect an employee's eligibility to
participate in any other benefit or incentive plan of the Company or any
subsidiary. Any Options granted pursuant to the Plan shall not be used in
determining the benefits provided under any other plan of the Company or any
subsidiary unless specifically provided.

21.  DURATION OF THE PLAN.

     The Plan shall remain in effect until all Options granted under the Plan
have been satisfied by the issuance of shares, but no Option shall be granted
more than ten years after the earlier of the date the Plan is adopted by the
Board or is approved by the Company's shareholders.

22.  FORFEITURE FOR DISHONESTY.

     Notwithstanding anything to the contrary in the Plan, if the Committee
finds, by a majority vote, after full consideration of the facts presented on
behalf of both the Company and any optionee, that the optionee has been engaged
in fraud, embezzlement, theft, commission of a felony or dishonest conduct in
the course of his employment or retention by the Company or any subsidiary that
damaged the Company or any subsidiary or that the optionee has disclosed trade
secrets of the Company or any subsidiary, the optionee shall forfeit all
unexercised Options and all exercised Options with respect to which the Company
has not yet delivered the certificates. The decision of the Committee in
interpreting and applying the provisions of this Section 22 shall be final. No
decision of the Committee shall affect the finality of the discharge or
termination of such optionee by the Company or any subsidiary in any manner.

23.  NO PROHIBITION ON CORPORATE ACTION.

     No provision of the Plan shall be construed to prevent the Company or any
officer or director thereof from taking any corporate action deemed by the
Company or such officer or director to be appropriate or in the Company's best
interest, whether or not such action could have an adverse effect on the Plan or
any Options granted hereunder, and no optionee or optionee's estate, personal
representative or beneficiary shall have any claim against the Company or any
officer or director thereof as a result of the taking of such action.

24.  INDEMNIFICATION.

     With respect to the administration of the Plan, the Company shall indemnify
each present and future member of the Committee and/or the Board against, and
each member of the Committee and the Board shall be entitled without further
action on his part to indemnity from the Company for all expenses (including the
amount of judgments and the amount of approved settlements made with a view to
the curtailment of costs of litigation, other than amounts paid to the Company
itself) reasonably incurred by him in connection with or arising out of, any
action, suit or proceeding in which he may be involved by reason of his being or
having been
                                       B-6


a member of the Committee and/or the Board, whether or not he continues to be
such member at the time of incurring such expenses; provided, however, that such
indemnity shall not include any expenses incurred by any such member of the
Committee and/or the Board (i) in respect of matters as to which he shall be
finally adjudged in any such action, suit or proceeding to have been guilty of
gross negligence or willful misconduct in the performance of his duty as such
member of the Committee and/or the Board; or (ii) in respect of any matter in
which any settlement is effected for an amount in excess of the amount approved
by the Company on the advice of its legal counsel; and provided further that no
right of indemnification under the provisions set forth herein shall be
available to or enforceable by any such member of the Committee and/or the Board
unless, within 60 days after institution of any such action, suit or proceeding,
he shall have offered the Company in writing the opportunity to handle and
defend same at its own expense. The foregoing right of indemnification shall
inure to the benefit of the heirs, executors or administrators of each such
member of the Committee and the Board and shall be in addition to all other
rights to which such member may be entitled as a matter of law, contract or
otherwise.

25.  MISCELLANEOUS PROVISIONS.

     (a) Compliance with Plan Provisions.  No optionee or other person shall
have any right with respect to the Plan, the Common Stock reserved for issuance
under the Plan or any Option until a written Option agreement shall have been
executed by the Company and the optionee and all the terms, conditions and
provisions of the Plan and the Option applicable to such optionee (and each
person claiming under or through him) have been met.

     (b) Approval of Counsel.  In the discretion of the Committee, no shares of
Common Stock, other securities or property of the Company, or other forms of
payment shall be issued hereunder with respect to any Option unless counsel for
the Company shall be satisfied that such issuance will be in compliance with
applicable federal, state, local and foreign legal, securities exchange and
other applicable requirements.

     (c) Compliance with Rule 16b-3.  To the extent that Rule 16b-3 under the
Exchange Act applies to Options granted under the Plan, it is the intent of the
Company that the Plan comply in all respects with the requirements of Rule
16b-3, that any ambiguities or inconsistencies in construction of the Plan be
interpreted to give effect to such intention and that if the Plan shall not so
comply, whether on the date of adoption or by reason of any later amendment to
or interpretation of Rule 16b-3, the provisions of the Plan shall be deemed to
be automatically amended so as to bring them into full compliance with such
rule.

     (d) Unfunded Plan.  The Plan shall be unfunded. The Company shall not be
required to establish any special or separate fund or to make any other
segregation of assets under the Plan.

     (e) Effects of Acceptance of Option.  By accepting any Option or other
benefit under the Plan, each optionee and each person claiming under or through
him shall be conclusively deemed to have indicated his acceptance and
ratification of, and consent to, any action taken under the Plan by the Company,
the Board and/or the Committee or its delegates.

     (f) Construction.  The masculine pronoun shall include the feminine and
neuter, and the singular shall include the plural, where the context so
indicates.

26.  SHAREHOLDER APPROVAL.

     The Company shall submit the Plan to the shareholders entitled to vote
hereon for approval within twelve months after the date of adoption by the Board
in order to meet the requirements of Section 422 of the Code and the regulations
thereunder. The exercise of any Option granted under the Plan shall be subject
to the approval of the Plan by the shareholders.

notice described in NRS 92A.430.

     2.  To the extent the subject corporation elects to withhold payment, after

demand payment of his estimate, less any payment pursuant to NRS 92A.460, or
reject the offer pursuant to NRS 92A.470 and demand payment of the fair value of
his shares and interest due, if he believes that the amount paid pursuant to NRS
92A.460 or offered pursuant to NRS 92A.470 is less than the fair value of his
shares or that the interest due is incorrectly calculated.

     2.  A dissenter waives his right to demand payment pursuant to this section
unless he notifies the subject corporation of his demand in writing within 30
days after the subject corporation made or offered payment for his shares.

SECTION 92A.490.  LEGAL PROCEEDING TO DETERMINE FAIR VALUE: DUTIES OF SUBJECT
                  CORPORATION; POWERS OF COURT; RIGHTS OF DISSENTER.

accrued interest. If the subject corporation does not commence the proceeding
within the 60-day period, it shall pay each dissenter whose demand remains
unsettled the amount demanded.

     2.  A subject corporation shall commence the proceeding in the district
court of the county where its registered office is located. If the subject
corporation is a foreign entity without a resident agent in the state, it shall
commence the proceeding in the county where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
entity was located.

     3.  The subject corporation shall make all dissenters, whether or not
residents of Nevada, whose demands remain unsettled, parties to the proceeding
as in an action against their shares. All parties must be served with a copy of
the petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.

     4.  The jurisdiction of the court in which the proceeding is commenced
under subsection 2 is plenary and exclusive. The court may appoint one or more
persons as appraisers to receive evidence and recommend a decision on the
question of fair value. The appraisers have the powers described in the order
appointing them, or any amendment thereto. The dissenters are entitled to the
same discovery rights as parties in other civil proceedings.

     5.  Each dissenter who is made a party to the proceeding is entitled to a
judgment:

          (a) For the amount, if any, by which the court finds the fair value of
     his shares, plus interest, exceeds the amount paid by the subject
     corporation; or

          (b) For the fair value, plus accrued interest, of his after-acquired
     shares for which the subject corporation elected to withhold payment
     pursuant to NRS 92A.470.

SECTION 92A.500.  LEGAL PROCEEDING TO DETERMINE FAIR VALUE: ASSESSMENT OF COSTS
                  AND FEES.

     1.  The court in a proceeding to determine fair value shall determine all
of the costs of the proceeding, including the reasonable compensation and
expenses of any appraisers appointed by the court. The court shall assess the
costs against the subject corporation, except that the court may assess costs
against all or some of the dissenters, in amounts the court finds equitable, to
the extent the court finds the dissenters acted arbitrarily, vexatiously or not
in good faith in demanding payment.

     2.  The court may also assess the fees and expenses of the counsel and
experts for the respective parties, in amounts the court finds equitable:

          (a) Against the subject corporation and in favor of all dissenters if
     the court finds the subject corporation did not substantially comply with
     the requirements of NRS 92A.300 to 92A.500, inclusive; or

          (b) Against either the subject corporation or a dissenter in favor of
     any other party, if the court finds that the party against whom the fees
     and expenses are assessed acted arbitrarily, vexatiously or not in good
     faith with respect to the rights provided by NRS 92A.300 to 92A.500,
     inclusive.

     3.  If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the subject corporation, the
court may award to those counsel reasonable fees to be paid out of the amounts
awarded to the dissenters who were benefited.

     4.  In a proceeding commenced pursuant to NRS 92A.460, the court may assess
the costs against the subject corporation, except that the court may assess
costs against all or some of the dissenters who are parties to the proceeding,
in amounts the court finds equitable, to the extent the court finds that such
parties did not act in good faith in instituting the proceeding.

     5.  This section does not preclude any party in a proceeding commenced
pursuant to NRS 92A.460 or 92A.490 from applying the provisions of N.R.C.P. 68
or NRS 17.115.

                PART II:  INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 8.75 of the Illinois Business Corporation Act of 1983 provides as
follows:

     (a) A corporation may indemnify any person who was or is a party, or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he or she is or was a director, officer, employee or agent of the
corporation, or who is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding, if
such person acted in good faith and in a manner he or she reasonably believed to
be in, or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his or her conduct was unlawful. The termination of any action, suit or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he or she reasonably
believed to be in or not opposed to the best interests of the corporation or,
with respect to any criminal action or proceeding, that the person had
reasonable cause to believe that his or her conduct was unlawful.

     (b) A corporation may indemnify any person who was or is a party, or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that such person is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees) actually and reasonably incurred by such person in connection with the
defense or settlement of such action or suit, if such person acted in good faith
and in a manner he or she reasonably believed to be in, or not opposed to, the
best interests of the corporation, provided that no indemnification shall be
made with respect to any claim, issue, or matter as to which such person has
been adjudged to have been liable to the corporation, unless, and only to the
extent that the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability, but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses as the court shall deem proper.

     (c) To the extent that a present or former director, officer or employee of
a corporation has been successful, on the merits or otherwise, in the defense of
any action, suit or proceeding referred to in subsections (a) and (b), or in
defense of any claim, issue or matter therein, such person shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection therewith, if the person acted in good faith and in a
manner he or she reasonably believed to be in, or not opposed to, the best
interests of the corporation.

     (d) Any indemnification under subsections (a) and (b) (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case,
upon a determination that indemnification of the present or former director,
officer, employee or agent is proper in the circumstances because he or she has
met the applicable standard of conduct set forth in subsections (a) or (b). Such
determination shall be made with respect to a person who is a director or
officer at the time of the determination: (1) by the majority vote of the
directors who are not parties to such action, suit or proceeding, even though
less than a quorum, (2) by a committee of the directors designated by a majority
vote of the directors, even though less than a quorum, (3) if there are no such
directors, or if the directors so direct, by independent legal counsel in a
written opinion, or (4) by the shareholders.

     (e) Expenses (including attorney's fees) incurred by an officer or director
in defending a civil or criminal action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the corporation as

                                       II-1


authorized in this Section. Such expenses (including attorney's fees) incurred
by former directors and officers or other employees and agents may be so paid on
such terms and conditions, if any, as the corporation deems appropriate.

     (f) The indemnification and advancement of expenses provided by or granted
under the other subsections of this Section shall not be deemed exclusive of any
other rights to which those seeking indemnification or advancement of expenses
may be entitled under any by-law, agreement, vote of shareholders or
disinterested directors, or otherwise, both as to action in his or her official
capacity and as to action in another capacity while holding such office.

     (g) A corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the corporation,
or who is or was serving at the request of the corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, against any liability asserted against such person
and incurred by such person in any such capacity, or arising out of his or her
status as such, whether or not the corporation would have the power to indemnify
such person against such liability under the provisions of this Section.

     (h) If a corporation indemnifies or advances expenses to a director or
officer under subsection (b) of this Section, the corporation shall report the
indemnification or advance in writing to the shareholders with or before the
notice of the next shareholders meeting.

     (i) For purposes of this Section, references to "the corporation" shall
include, in addition to the surviving corporation, any merging corporation
(including any corporation having merged with a merging corporation) absorbed in
a merger which, if its separate existence had continued, would have had the
power and authority to indemnify its directors, officers, and employees or
agents, so that any person who was a director, officer, employee or agent of
such merging corporation, or was serving at the request of such merging
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this Section with respect to the surviving
corporation as such person would have with respect to such merging corporation
if its separate existence had continued.

     (j) For purposes of this Section, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries. A person who acted in good faith and in a manner he or she
reasonably believed to be in the best interests of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interest of the corporation" as referred to in
this Section.

     (k) The indemnification and advancement of expenses provided by or granted
under this Section shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer, employee, or
agent and shall inure to the benefit of the heirs, executors, and administrators
of that person.

     The Donlar Amended and Restated Bylaws provide that Donlar shall, to the
fullest extent to which it is empowered to do so by the Illinois Business
Corporation Act of 1983 or any other applicable law, as may from time to time be
in effect, indemnify any person who was or is threatened to be made a party to
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was a director or officer of Donlar, or is or was serving at the request of
Donlar as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding.

     The Amended and Restated Bylaws also provide that Donlar shall have the
power to purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of Donlar or is or was serving at the
request of Donlar as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against any
liability asserted against him and incurred by
                                       II-2


him in any such capacity or arising out of his status as such whether or not
Donlar would have the power to indemnify him against such liability under the
provisions of the Amended and Restated Bylaws.

ITEM 22.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes as follows:

          (1) that insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the provisions described
     under Item 20 above, or otherwise, the registrant has been advised that in
     the opinion of the Securities and Exchange Commission such indemnification
     is against public policy as expressed in the Act and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the registrant of expenses incurred
     or paid by a director, officer or controlling person of the registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person in connection with the
     securities being registered, the registrant will, unless in the opinion of
     its counsel the matter has been settled by controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed in the Act and
     will be governed by the final adjudication of such issue.

          (2) to respond to requests for information that is incorporated by
     reference into the registration statement pursuant to Items 4, 10(b), 11 or
     13 of Form S-4, within one business day of receipt of such request, and to
     send the incorporated documents by first class mail or other equally prompt
     means. This includes information contained in documents filed subsequent to
     the effective date of the registration statement through the date of
     responding to the request.

          (3) to supply by means of a post-effective amendment all information
     concerning the Merger and related transactions and Donlar Biosyntrex that
     was not the subject of and included in the registration statement when it
     became effective.

                                       II-4


                                   SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this registration statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in Bedford Park, Illinois York on this
16th day of January, 2003.
